Description

The present invention relates to a bathtub handrail that can be detachably attached to a bathtub side wall, which guarantees smooth movement of the pressing portion, and in particular, a fixed frame mounted on the upper surface of the bathtub side wall and slidable on the fixed frame. In the bathtub handrail consisting of the movable frame attached to the movable frame, the pressing portion movably attached to the movable frame is prevented from being caught by the step formed by the lower surface of the movable frame and the end portion of the fixed frame. Regarding the handrails for bathtubs.

Conventionally, a bathtub handrail that can be detachably attached by clamping the side wall of the bathtub from the washing area side and the bathtub side so that the elderly can easily support the body when entering and exiting the bathtub has been used. Are known.

In addition, many of these bathtub handrails consist of a fixed frame mounted on the upper surface of the bathtub side wall, a movable frame slidably mounted on the fixed frame, and further clamp the bathtub side wall. The pressing portion for moving forward and backward is of a type attached to a fixed frame as described in, for example, Japanese Patent Application Laid-Open No. 2015-173649 (Patent Document 1), and for example, Japanese Patent Application Laid-Open No. 2005-7011 (Patent). It is known that the type is roughly classified into the type attached to the movable frame as described in Document 2).

In the case of the handrail for bathtub of the type described in Patent Document 1, since the fixed frame is placed on the upper surface of the side wall of the bathtub, the pressing portion attached to the fixed frame includes the vertical portion of the fixed frame and the side wall of the bathtub. It will move between the flat surfaces of the horizontal portion of the fixed frame.

On the other hand, in the case of the handrail for bathtub of the type described in Patent Document 2, since the movable frame is mounted on the fixed frame placed beyond the upper surface width of the side wall of the bathtub, it is mounted on the movable frame. The pressed portion moves between the vertical portion of the movable frame and the side wall of the bathtub along the horizontal portion of the movable frame and the horizontal portion of the fixed frame arranged on the lower surface thereof. Further, in the case of this type of bathtub handrail, a step is formed on the lower surface of the horizontal portion of the movable frame by the end portion of the horizontal portion of the fixed frame.

By the way, since the general means of moving the pressing portion is to rotate either the bolt or the nut to screw the bolt back and forth, the pressing portion attached to the bolt is somewhere in the movable frame with respect to the movable frame. It has the characteristic that it rotates until it interferes with the part of. Therefore, in the handrail for bathtub of Patent Document 2, there is a problem that the pressing portion interferes with the step formed by the lower surface of the movable frame and the end portion of the fixed frame when moving, and cannot move smoothly (particularly forward). there were. Further, the rotation of the pressing portion during movement can be stopped by interposing the user's hand when moving the pressing portion so that the pressing portion does not get caught in the step of the movable frame. In this case, the user's hand There is also a problem that the risk of being caught in a movable frame or a fixed frame increases and it is dangerous.

Further, in a bathtub handrail of a type in which a pressing portion is attached to a movable frame, in order to eliminate a step formed on the lower surface of a horizontal portion of the movable frame, for example, Japanese Patent Application Laid-Open No. 2005-95492 (Patent Document 3) As described, after shortening the horizontal part of the fixed frame, the fixed frame and the movable frame can be connected at the same level by using a dedicated connecting plate, or the fixed frame and the movable frame can be connected. A handrail for bathtubs has been developed with the horizontal part of the wall thinned.

However, even in the type of bathtub handrail described in Cited Document 3, the step formed on the lower surface of the horizontal portion of the movable frame is not sufficiently eliminated, and if a dedicated connecting plate is used, the bathtub handrail is used. There is a problem that the structure of the bathtub becomes complicated and the attachment to the side wall of the bathtub becomes complicated. Further, if the horizontal portion of the fixed frame and the movable frame is thinned, there is a problem that a handrail for a bathtub having sufficient strength that can be adapted to a unit bath that does not use a strength member in a part thereof cannot be obtained. there were.

Therefore, the present invention is a handrail for a bathtub including a fixed frame mounted on the upper surface of the side wall of the bathtub and a movable frame slidably mounted on the fixed frame, which is movably attached to the movable frame. It is an object of the present invention to provide a handrail for a bathtub in which the pressed portion is prevented from being caught by a step formed by a lower surface of a movable frame and an end portion of a fixed frame.

As a result of diligent studies on the structure and shape of the fixed frame and the movable frame for eliminating the step formed by the lower surface of the movable frame and the end of the fixed frame, the present inventors have made a part of the movable frame. It was found that the above problem can be solved most effectively by providing a level correction tool that forms the same level as the lower surface of the fixed frame in the fixed frame and providing an opening in the fixed frame that can accept the level correction tool. , The present invention has been completed.

That is, according to the present invention, in a handrail for a bathtub including a fixed frame directly placed on the upper surface of the side wall of the bathtub and a movable frame slidably attached on the fixed frame, the movable frame is a bathtub. In order to press one side surface of the side wall, a pressing portion that is close to and separated from the movable frame and a lower end portion that becomes substantially the same level as the bottom surface of the fixed frame when the movable frame is attached to the fixed frame. A bathtub railing with a skirt provided is provided.

The basic form of the handrail for a bathtub of the present invention is a movable portion having a fixed frame having a mounting portion of a horizontal portion mounted on the upper surface of the side wall of the bathtub and a sliding portion mounted on the mounting portion of the fixed frame. The vertical portion provided with the frame and constituting the vertical portion of the movable frame is equipped with a pressing portion that moves forward and backward with respect to the vertical portion of the movable frame in order to press the side wall of the bathtub. The frame width and slide length of the movable frame are not particularly limited, but in the handrail for bathtub of the present invention, the frame width of the slide portion of the movable frame is narrower than the frame width of the mounting portion of the fixed frame, and the slide is made. By increasing the length, the lightweight structure makes it possible to fit the side walls of bathtubs of various thicknesses.

The slide portion of the movable frame is provided with a skirt having a lower end portion that becomes substantially the same level as the bottom surface of the mounting portion of the fixed frame when the movable frame is attached to the fixed frame. However, the skirt does not need to be provided over the entire length of the slide portion of the movable frame, and it is sufficient if the length is within the range in which the pressing portion moves with respect to the movable frame.

For example, when the bottom surface of the slide portion of the movable frame is flat, the skirt may be in the form of a rib extending downward from the bottom surface of the slide portion of the movable frame and in the slide direction of the movable frame. Further, when the bottom surface of the slide portion of the movable frame is flat as described above, it is preferable that the skirts are arranged in each of the left side region and the right side region in the width direction of the slide portion.

For example, when the movable frame has a downward U-shape in a cross section orthogonal to the slide direction, the side walls formed at both ends of the downward U-shaped cross section of the slide portion are the bottom surface of the mounting portion of the fixed frame. If the lower end portion having substantially the same level is provided, the side wall portion having the lower end surface can be used (also used) as a skirt.

Further, when the skirt forms a wall extending below the slide portion of the movable frame, the skirt can also function as a reinforcing rib of the movable frame.

In the present invention, it is preferable that the skirts are arranged in each of the left side region and the right side region in the width direction of the slide portion, so that the rotation generated when the pressing portion moves is performed at two locations in the width direction of the upper end portion of the pressing portion. This is because the pressing portion can be stably screwed back and forth by restricting from.

That is, since the general means for moving the pressing portion is to rotate either the bolt or the nut to screw the bolt back and forth, the pressing portion attached to the bolt rotates during movement. However, in the present invention, when the pressing portion rotates, the left side region or the right side region of the upper end portion of the pressing portion comes into contact with the lower end portion of the skirt, so that unlimited rotation that occurs when the pressing portion moves is reliably restricted. Moreover, since the lower end of the skirt is set to almost the same level as the bottom surface of the fixed frame mounting portion, when moving, the pressing portion is the lower end of the movable frame skirt and the bottom surface of the fixed frame mounting portion. It can move smoothly without getting caught between them.

In the present invention, the skirt does not have to be configured as an integral part forming a part of the movable frame, and may be configured to be detachably attached to the movable frame as a separate part separated from the movable frame.

For example, when the skirt is configured to have a downward U-shape in a cross-sectional view, the skirt slides into the slide portion of the movable frame by sliding it from the lateral direction or by fitting it from above. Can be easily slid onto the top. Further, since the skirt is not required to have high rigidity like the movable frame if it has a predetermined lower end portion, it is excessive by separating the skirt where the shape is important from the movable frame where the strength is important. It is possible to suppress the use of materials and manufacture efficiently.

When the length of the skirt along the sliding direction of the movable frame is constant, the fixed frame of the bathtub handrail is in contact with the other side surface opposite to the side surface of the bathtub side wall pressed by the pressing part. And preferably have a notch capable of accepting the skirt in the sliding direction.

The handrail for a bathtub of the present invention is a movable frame by providing a contact portion with a contact base constituting a vertical portion (vertical member) of the fixed frame in a fixed frame directly placed on the upper surface of the side wall of the bathtub. Even if the pressing part attached to the bathtub is pressed from the opposite side of the side wall of the bathtub, the fixed frame and the upper surface of the side wall of the bathtub do not come into contact with each other without causing positional deviation or stress (friction force). It can be firmly attached to the side wall of the bathtub by the clamping force of the portion and the pressing portion.

Further, the handrail for a bathtub of the present invention is provided with a notch in the mounting portion constituting the horizontal portion (horizontal member) of the fixed frame so that the rib of the skirt having a predetermined lower end can be received in the sliding direction. As a result, even if the length of the movable frame in the sliding direction cannot be adjusted, the movable frame can be freely brought close to and separated from the fixed frame without causing the skirt to interfere with the fixed frame.

For example, when the movable frame is fixed at the position farthest from the fixed frame, a step is formed on the lower surface of the slide portion forming the horizontal portion (horizontal member) of the movable frame due to the end portion of the mounting portion of the fixed frame that overlaps. Is formed. However, in the handrail for bathtub of the present invention, the bottom surface of the slide portion of the movable frame is connected to substantially the same level as the bottom surface of the mounting portion of the fixed frame via the lower end portion of the skirt within the range in which the pressing portion moves. Therefore, smooth movement of the pressing portion between the movable frame and the fixed frame is guaranteed without causing catching.

On the other hand, when trying to fix the movable frame to the position closest to the fixed frame, the rib of the skirt with the lower end interferes with the mounting part of the fixed frame, and the movable frame is made shorter than the length of the skirt. You will not be able to get close to the fixed frame. However, in the handrail for bathtub of the present invention, since the notch for receiving the rib of the skirt in the sliding direction is provided in the mounting portion of the fixed frame, the rib of the skirt interferes with the mounting portion of the fixed frame. Most of the sliding portion of the movable frame can be brought close to the mounting portion of the fixed frame so as to overlap with each other.

Further, in the bathtub handrail of the present invention, even when most of the sliding portion of the movable frame overlaps with the mounting portion of the fixed frame, the lower end portion of the skirt is in contact with the bottom surface of the mounting portion in the notch of the fixed frame. Since it is held at substantially the same level, the pressing portion between the movable frame and the fixed frame can be smoothly pressed without getting caught, as in the case where the movable frame is fixed at the position farthest from the fixed frame. Movement is guaranteed.

In the bathtub handrail of the present invention, the length of the skirt along the sliding direction of the movable frame is adjusted regardless of whether or not the mounting portion of the fixed frame has a notch for accepting the skirt in the sliding direction. It can also be made possible. In this case, the skirt is preferably configured as a separate part that is separate and independent of the movable frame. For example, all or part of the skirt (for example, ribs) is divided into two or more short split skirts in the sliding direction of the movable frame. Thereby, the length of the entire skirt can be adjusted as a connecting body of the divided skirts.

As one embodiment of the split skirt, a plurality of split skirts having a short length that can be attached to and detached from the movable frame are prepared in advance, and a skirt is selected by selecting the number of split skirts to be attached to the slide portion of the movable frame. The overall length can be adjusted. In this case, the split skirt is preferably flexible and has a downward U-shape in cross-sectional view, and can be fitted into the slide portion of the movable frame from above or from the lateral direction. By inserting the slide, it can be easily attached to and detached from the slide portion.

The length of the split skirt along the sliding direction of the movable frame is arbitrary and is not particularly limited, but the shorter the length of the split skirt, the finer the length of the entire skirt can be adjusted. For example, in the case of a type in which the slide part of the movable frame is fixed to the mounting part of the fixed frame by screwing, at least one type of split skirt has the same length as the pitch of the screw holes used for screwing. It is more preferable that a split skirt having a length equal to or less than the pitch of the screw holes is prepared. Further, if a plurality of divided skirts having different lengths are prepared, the length of the entire skirt can be adjusted more widely and finely.

In the case of a handrail for bathtubs in which a movable frame is mounted on a fixed frame, when the movable frame is fixed at the position farthest from the fixed frame, the slide portion constituting the horizontal portion (horizontal member) of the movable frame. A step is formed on the lower surface of the above by the ends of the mounting portions of the overlapping fixed frames. However, in the case of the present embodiment, by mounting the above-mentioned split skirt in the entire area of the slide portion in the range where the pressing portion moves, the lower end portion of the region where the split skirt of the slide portion is mounted is mounted on the fixed frame. Since it is connected to substantially the same level as the bottom surface of the placement portion, smooth movement of the pressing portion between the movable frame and the fixed frame is guaranteed without causing catching.

On the other hand, when trying to fix the movable frame to the position closest to the fixed frame, the rib of the skirt with the lower end interferes with the mounting part of the fixed frame, and the movable frame is made shorter than the length of the skirt. You will not be able to get close to the fixed frame. However, in the case of the present embodiment, the length of the entire skirt can be freely adjusted by selecting the number of split skirts to be attached to the slide portion of the movable frame, so that the ribs of the split skirt interfere with the mounting portion of the fixed frame. Most of the sliding portion of the movable frame can be brought close to the mounting portion of the fixed frame so as to overlap with each other.

Further, since the split skirts of arbitrary length and number can be attached to the slide portion of the movable frame protruding from the mounting portion of the fixed frame according to the range in which the pressing portion moves, the split skirts are attached. The lower end of the slide portion of the area is held at approximately the same level as the bottom surface of the mounting portion of the fixed frame, resulting in catching as in the case of fixing the movable frame at the position farthest from the fixed frame. The smooth movement of the pressing portion between the movable frame and the fixed frame is guaranteed.

In another embodiment of the split skirt, a fixed frame is mounted by shaping the skirt into a downward U-shape in cross section and splitting only the ribs with the lower ends of the skirt into two or more short split ribs. The length of the ribs on the skirt that interferes with the placement can be adjusted. In this case, each of the plurality of divided ribs is attached to the horizontal portion of the skirt via a rotating means such as a hinge, and is flipped up along a plane orthogonal to the sliding direction of the movable frame. It is preferable that it can be rotated as described above.

The length of the split ribs of the split skirt along the slide direction of the movable frame is arbitrary and is not particularly limited, but the shorter the length of each split rib, the more the entire rib that interferes with the mounting part of the fixed frame. The length can be finely adjusted. For example, in the case of a type in which the slide part of the movable frame is fixed to the mounting part of the fixed frame by screwing, at least one type of split rib length is the same as the pitch of the screw holes used for screwing. It is more preferable that the split ribs having a length equal to or less than the pitch of the screw holes are prepared.

In the case of a handrail for bathtubs in which a movable frame is mounted on a fixed frame, when the movable frame is fixed at the position farthest from the fixed frame, the slide portion constituting the horizontal portion (horizontal member) of the movable frame. A step is formed on the lower surface of the above by the ends of the mounting portions of the overlapping fixed frames. However, in the case of the present embodiment, of the split skirts mounted on the slide portion, only the split ribs in the range where the slide portion is arranged above the mounting portion of the fixed frame are flipped up, and other than the mounting portion of the fixed frame. By tilting only the split ribs in the range where the pressing portion moves with, the lower end of the slide portion in the area where the split ribs are tilted downward is connected to substantially the same level as the bottom surface of the mounting portion of the fixed frame. Therefore, smooth movement of the pressing portion between the movable frame and the fixed frame is guaranteed without causing catching.

On the other hand, when trying to fix the movable frame to the position closest to the fixed frame, the rib of the skirt with the lower end interferes with the mounting part of the fixed frame, and the movable frame is made shorter than the length of the skirt. You will not be able to get close to the fixed frame. However, in the case of the present embodiment, the slide portion is the upper part of the mounting portion of the fixed frame among the split skirts attached to the slide portion, as in the case where the movable frame is fixed at the position farthest from the fixed frame. By flipping up only the split ribs in the range arranged in, and tilting only the split ribs in the range where the pressing part moves other than the mounting part of the fixed frame, the split ribs of the split skirt can be placed in the fixed frame mounting part. Most of the sliding portion of the movable frame can be brought close to the mounting portion of the fixed frame so as to overlap with each other without interfering with the sliding portion of the movable frame.

In addition, the lower end of the split rib that is tilted downward is connected to the slide part of the movable frame that protrudes from the mounting part of the fixed frame at almost the same level as the bottom surface of the mounting part of the fixed frame, so that it can be caught. Smooth movement of the pressing portion between the movable frame and the fixed frame is guaranteed without occurring.

As described above, an object of the present invention is to prevent a pressing portion movably attached to the movable frame from being caught by a step formed on the lower surface of the movable frame by the end portion of the fixed frame. .. For this reason, as a type of moving means for the pressing portion that can most enjoy the benefits according to the present invention, there is one that rotates either the bolt or the nut to screw the bolt while transmitting the rotational power to the bolt.

More specifically, a bolt that supports the pressing portion, a nut that is screwed to the bolt and rotatably attached to the vertical portion that constitutes the vertical member of the movable frame, and a handle for rotating the nut. Rotate the moving means including the knob, the bolt that supports the pressing part, the nut that is screwed with the bolt and fixed to the vertical part that constitutes the vertical member of the movable frame, and the bolt. Transportation means including a handle knob for movement can be cited as the type of transportation means that can most benefit from the application of the skirt and notch, or split skirt according to the present invention.

Further, in the handrail for a bathtub of the present invention, a fixed frame having an inverted L shape in a side view is placed directly on the side wall of the bathtub, and the inverted L is placed on a mounting portion constituting a horizontal member of the fixed frame. By attaching a movable frame having a shape, even if the pressing portion attached to the movable frame is pressed against the side wall of the bathtub, a positional shift or stress (friction force) is generated between the fixed frame and the upper surface of the side wall of the bathtub. It is characterized in that it can be firmly attached to the side wall of the bathtub by the clamping force of the contact portion and the pressing portion.

Therefore, in the present invention, in order to make the best use of the above features, the handrail main body arranged above the side wall for the bathtub and above the fixed frame is displaced in relation to the upper surface of the side wall of the bathtub. It is preferable to attach it to the fixed frame side that does not generate stress (friction force). Further, in the present invention, since the pressing portion and the moving means thereof are attached to the movable frame set on the bathtub side instead of the washing place side, the inside of the bathtub of the handle knob for screwing back and forth the pressing portion and the bolt supporting the pressing portion. It is preferable that the amount of protrusion to the sill is suppressed as much as possible. Therefore, in the handrail for bathtub of the present invention, of the above-mentioned two types of moving means for the pressing portion, the former type of moving means in which the position of the handle knob does not change with respect to the movable frame even when rotated can be adopted. preferable.

According to the handrail for a bathtub of the present invention, the mounting portion constituting the horizontal portion (horizontal member) of the fixed frame is provided with a notch capable of receiving the rib of the skirt having a predetermined lower end portion in the sliding direction. As a result, the bottom surface of the slide portion of the movable frame can be connected to substantially the same level as the bottom surface of the mounting portion of the fixed frame via the lower end portion of the skirt regardless of the proximity and separation position of the movable frame with respect to the fixed frame. It is possible to guarantee smooth movement between the movable frame and the fixed frame without causing catching due to a step.

According to the handrail for a bathtub of the present invention, the length of the entire skirt can be adjusted by dividing the skirt to be attached to the movable frame into a plurality of divided skirts having a short length, so that the length of the entire skirt can be adjusted with respect to the fixed frame. Regardless of the proximity and separation position of the movable frame, the bottom surface of the slide part of the movable frame can be connected to almost the same level as the bottom surface of the mounting part of the fixed frame via the lower end of the skirt, so that the pressing part is caught by a step. Smooth movement between the movable frame and the fixed frame can be guaranteed without causing it.

According to the bathtub handrail of the present invention, a fixed frame having an inverted L shape in a side view is directly placed on the side wall of the bathtub, and a mounting portion constituting a horizontal member of the fixed frame. By attaching a movable frame having an inverted L shape on the top, even if the pressing part attached to the movable frame is pressed against the side wall of the bathtub, the position shift and stress (positional deviation and stress between the fixed frame and the upper surface of the side wall of the bathtub ( It can be firmly attached to the side wall of the bathtub by the clamping force of the contact portion and the pressing portion without generating frictional force).

According to the bathtub handrail of the bathtub handrail of the present invention, the moving means of the pressing portion attached to the bathtub side via the movable frame is a bolt supporting the pressing portion and a bolt screwed with the bolt and of the movable frame. Since it can be composed of a nut that is rotatably attached to the vertical part that constitutes the vertical member and a handle knob for rotating the nut, the position with respect to the movable frame changes even if the handle knob is rotated. However, it is safe for the user because the amount of protrusion into the bathtub can be suppressed.

Hereinafter, the handrail for a bathtub according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the examples shown below, and various modifications can be made without departing from the technical idea of the present invention.

1. 1. The main configuration of the handrail 1 for a bathtub according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 shows an overall outline of bathtub handrails 1, 1a, 1b common to the first, second, and third embodiments of the present invention, and FIG. 2 shows the implementation shown in FIG. Among the embodiments, a mode in which the bathtub handrail 1 of the first embodiment is disassembled into main parts is shown.

As shown in FIGS. 1 and 2, the basic skeleton of the bathtub handrail 1 is connected to a mounting portion 21 which is directly mounted on the upper surface of the bathtub side wall and a mounting portion 21, and is connected to the bathtub side wall. An inverted L-shaped fixed frame 2 having an abutting base 22 abutting on one side surface, a slide portion 31 slidably mounted on a mounting portion 21 of the fixed frame 2, and a slide portion 31. It is composed of an inverted L-shaped movable frame 3 including a vertical portion 32 which is connected to the bathtub and is in contact with another side surface of the side wall of the bathtub. Further, a skirt 4 having a lower end portion 41 which is substantially the same level as the bottom surface of the mounting portion 21 of the fixed frame 2 when the movable frame 3 is attached to the fixed frame 2 is attached to and detached from the slide portion 31 of the movable frame 3. It is attached freely.

Although the frame width and slide length of the movable frame 3 are not particularly limited, in the bathtub handrail 1 of the present embodiment, the frame width of the slide portion 31 of the movable frame 3 is set to the mounting portion 21 of the fixed frame 2. By making the width narrower than the frame width and making the slide length longer, the lightweight structure makes it possible to fit the side walls of bathtubs of various thicknesses.

A contact portion 23 that contacts the side surface of the bathtub side wall is attached to the inside of the contact base 22 of the fixed frame 2, and a main grip 24 for supporting the user's body is attached to the outside of the contact base 22. And the leg portion 25 for preventing the handrail 1 for the bathtub from tilting is attached. On the other hand, the vertical portion 32 of the movable frame 3 includes a moving device 6 for advancing and retracting the pressing portion 5 that presses the side surface of the bathtub side wall opposite to the contact portion 23, and the movement of the user in the bathtub. A sub-grip 33 for assisting is attached. Further, the moving device 6 includes a handle knob 62 for rotating the nut 61 and a cap 620 thereof, and a plate-shaped pressing portion having a rectangular flat surface is provided at the tip of the bolt 63 which is screwed back and forth by the rotation of the nut 61. 5 is attached so as to swing freely.

Further, in the bathtub handrail 1 of the present embodiment, the mounting portion 21 of the fixed frame 2, the sliding portion 31 of the movable frame 3, and the vertical of the movable frame 3 are used by using the removable protective covers 26 and 34. By covering the portion 32, dangerous parts such as uneven parts are reduced, erroneous operations of parts that normally do not need to be operated are prevented, and the appearance is visually improved and cleaned (see FIG. 2).

The main grip 24 includes a ring-shaped upper grip 240 having a substantially rectangular plan view, and a pair of grip support portions 242 connected to the upper grip 240 and provided with a plurality of fixing holes 241. The main grip 24 can be adjustably fixed to an arbitrary height by inserting the insertion pin 270 of the insertion / release means 27 of the fixing frame 2 described later into the fixing hole 241 of the grip support portion 242.

The leg portion 25 is assisted by providing a main landing gear portion 251 screwed to the fixing frame 2 by a screw 250 and a male screw portion screwing with a female screw portion provided inside the main landing gear portion 251 on the outer peripheral surface. It is composed of a leg portion 252. The length of the leg portion 25 can be adjusted by rotating the auxiliary leg portion 252 with respect to the main landing gear portion 251.

FIG. 3 shows a rear view of the fixed frame 2 of the bathtub handrail 1 of the present embodiment. As will be understood with reference to FIG. 3, the mounting portion 21 of the fixed frame 2 of the present embodiment has two reinforcements continuously extending from the mounting portion 21 to the contact base portion 22 described later. The rib 20, a pair of notches 7 for receiving the skirt 4 attached to the slide portion 31 of the movable frame 3, and the width direction of the mounting portion 21 extend outward from the grip support portion 242. An extension 28 is provided.

When a horizontal force is applied to the main grip 24 along the longitudinal direction of the bathtub side wall, the extension portion 28 abuts on the upper surface of the bathtub side wall to resist the rotational moment acting on the main grip 24. Since the grip 24 is supported, the main grip 24 strongly prevents the main grip 24 from rotating or tipping over in the longitudinal direction of the bathtub side wall on the upper surface of the bathtub side wall. The "width direction of the mounting portion 21" means a horizontal direction in a direction orthogonal to the direction in which the contact portion 23 and the pressing portion 5 clamp the side wall of the bathtub in the mounting portion 21 of the fixed frame 2. When the bathtub handrail 1 is attached to the side wall of the bathtub, the direction substantially coincides with the longitudinal direction of the upper surface of the side wall of the bathtub.

On the other hand, the contact base 22 of the fixed frame 2 is provided with a cylindrical grip support accommodating portion 29 for slidably receiving a pair of grip support portions 242. Further, between the pair of grip support accommodating portions 29, a pair of insertion pins 270, a pair of knobs 271 attached to the rear end of the insertion pins 270, and an insertion pin 270 are placed in the grip support portion 242. An insertion / release means 27 including an urging means 272 for urging toward is provided.

The insertion pin 270 is removably inserted into at least one of a plurality of fixing holes 241 (FIG. 2) of the grip support portion 242 through a through hole (not shown) of the grip support portion accommodating portion 29. Further, the vine-wound spring-shaped urging means 272 urges the insertion pin 270 from the outside of the through hole of the grip support portion accommodating portion 29 toward the fixing hole 241 of the grip support portion 242. The knob 271 is operated by the user to apply a force to the urging means 272 in the direction opposite to the urging direction of the insertion pin 270 by the urging means 272.

As described above, in the bathtub handrail 1 of the present embodiment, the grip support portion 242 of the main grip 24 has a height on the back surface of the contact base portion 22 of the fixed frame 2 by the grip support portion accommodating portion 29 and the insertion release mechanism 27. It is fixed in an adjustable manner. That is, when the insertion pin 270 of the insertion release mechanism 27 is inserted into the fixing hole 241 of the grip support portion 242, the main grip 24 is connected and fixed to the fixing frame 2, while the insertion pin 270 is fixed to the grip support portion 242. The main grip 24 is not connected or fixed to the fixed frame 2 when it is not inserted into the hole 241.

Further, the grip support portion accommodating portion 29 includes a reduced diameter portion 290 for fixing the grip support portion 242 while suppressing rattling, and a nut 291 screwed onto the outer peripheral surface of the reduced diameter portion 290. .. The reduced diameter portion 290 is a slit provided in the upper part of the grip support portion accommodating portion 29. Further, a screw thread (thread groove) is provided on the outer peripheral surface of the reduced diameter portion 290, and the outer peripheral surface is tapered so that the outer diameter gradually increases from the upper side to the lower side. Therefore, when the nut 291 is attached to the thread (thread groove) of the reduced diameter portion 290 and the nut 291 is rotated so as to be screwed downward, the reduced diameter portion 290 is reduced in diameter by the nut 291 and thus grips are supported. The portion 242 is fixed into the grip support portion accommodating portion 29 without rattling.

FIG. 4 shows a cross-sectional view of the bathtub handrail 1 according to the present embodiment cut out along the axis of the bolt 63. The fixed frame 2 of the bathtub handrail 1 has a mounting portion 21 and a contact base portion 22 having a contact portion 23 connected to the mounting portion 21 and abutted against one side surface of the side wall of the bathtub. It contains and has an inverted L-shaped cross-sectional shape as a whole. Further, the movable frame 3 that can be slidably and detachably attached to the fixed frame 2 includes a slide portion 31 and a vertical portion 32 connected to the slide portion 31, and has a substantially L-shaped cross section downward as a whole. Have. Further, elastic resin rubbers 210 and 230 are attached to the inner surface of the mounting portion 21 of the fixed frame 2 and the inner surface of the contact portion 23, respectively, to prevent damage to the side wall of the bathtub and prevent slipping.

The nut 61 of the moving device 6 is rotatably attached to the vertical portion 31 of the movable frame 3, and the above-mentioned contact portion 23 is applied to the tip of the bolt 63 that is screwed back and forth by the rotation of the nut 61. A pressing portion 5 that presses the side surface opposite to the side wall of the bathtub that is in contact with the side wall is attached so as to swing freely. Further, the nut 61 is rotated by the handle knob 62 via the torque transmission / shutoff means 64 described later.

As shown in FIGS. 4 and 2, on the upper surface of the mounting portion 21 of the fixed frame 2, a plurality of fixing screw holes 211 arranged at equal pitches along the sliding direction of the movable frame 3 are provided. A pair of guide screw holes 212 are provided in a direction orthogonal to the arrangement direction of the fixing screw holes 211 and arranged at positions symmetrical with respect to the arrangement of the fixing screw holes 211.

On the other hand, the slide portion 31 of the movable frame 3 is provided with a pair of slits 310 that are aligned with the pair of guide screw holes 212 of the fixed frame 2 and are parallel to each other and extend in the slide direction of the movable frame 3. Has been done. Further, the slide portion 31 is provided with a plurality of through holes 311 between the pair of slits 310 along the slide direction of the movable frame 3 at the same pitch as the fixing screw holes 211 of the fixed frame 2. .. The through holes 311 are arranged so that the number of through holes 311 is larger than the number of fixing screw holes 211 of the fixing frame 2 and the distance between the through holes arranged at both ends is longer than the length of the slit 310.

Therefore, the bathtub handrail 1 according to the present embodiment passes through the slit 310 through the guide screw 312 having a head having a diameter larger than the width of the slit 310 into each of the pair of slits 310 of the movable frame 3. By attaching the movable frame 3 to the guide fixing hole 212 of the fixed frame 2, the movable frame 3 can be positioned with respect to the fixed frame 2 so that the sliding direction is restricted in one direction without being separated from the fixed frame 2. it can. Further, after determining the position of the movable frame 3 with respect to the fixed frame 2, the movable frame is passed through the through hole 311 of the movable frame 3 and the fixing screw 313 is screwed into the fixing screw hole 211 of the fixed frame 2. 3 can be firmly fixed at a desired position of the fixing frame 2.

As described above, in the bathtub handrail 1 of the present embodiment, the vertical portion 32 of the movable frame 3 is moved to the contact base 22 and the contact portion 23 of the fixed frame 2 as much as possible in advance according to the thickness of the bathtub side wall. Since they can be kept close to each other, the moving distance of the pressing portion 5 required for clamping the side wall of the bathtub can be suppressed to the minimum necessary. Therefore, the moving device 6 including the bolt 63 and the like for screwing the pressing portion 5 toward the contact portion 23 can be designed compactly.

In FIG. 5, in the bathtub handrail 1 of the first embodiment, the fixed frame 2 and the movable frame 3 are (a) separated, (b) separated and connected, and (c) close to each other. A schematic diagram of each is shown. FIG. 6 shows the side surfaces of the bathtub railing 1 of the present embodiment shown in FIG. 5, in which the fixed frame 2 and the movable frame 3 are (a) separated and connected (b) close to each other. The figure is shown.

As will be well understood with reference to FIGS. 5 and 6, when the movable frame 3 is attached to the fixed frame 2, the slide portion 31 of the movable frame 3 has a bottom surface 213 of the mounting portion 21 of the fixed frame 2. A skirt 4 having a lower end 41 at substantially the same level is provided. However, the length of the skirt 4 is shorter than the total length of the slide portion 31 of the movable frame 3, and is set to the length within the range in which the pressing portion 5 moves with respect to the movable frame 3 (FIGS. 6A and 6B). )).

In the case of the present embodiment, since the bottom surface of the slide portion 31 of the movable frame 3 is flat, the skirt 4 extends downward from the bottom surface of the slide portion 31 of the movable frame 3 and in the slide direction of the movable frame 3 when attached. It has a rib-like shape (Fig. 5 (b)). Further, the skirt 4 is arranged so as to form ribs perpendicular to each of the left side region and the right side region in the width direction of the slide portion 31 (FIG. 5A).

In the present embodiment, when the skirt 4 is attached, the skirt 4 is arranged in each of the left side region and the right side region in the width direction of the slide portion 31, so that the rotation generated when the pressing portion 5 moves is generated by the upper end portion of the pressing portion 5. By restricting from two points in the width direction of the above, the pressing portion 5 can be stably screwed back and forth.

That is, since the moving means 6 of the pressing portion 5 of the present embodiment rotates the nut 61 to screw the bolt 63 back and forth, the pressing portion 5 attached to the bolt 63 rotates during movement. However, in the present embodiment, when the pressing portion 5 rotates, the left side region or the right side region of the upper end portion of the pressing portion 5 comes into contact with the lower end portion 41 of the skirt 4, so that the unlimited rotation that occurs when the pressing portion 5 moves is surely performed. Be regulated. Moreover, since the lower end 41 of the skirt 4 is set to substantially the same level as the bottom surface 213 of the mounting portion 21 of the fixed frame 2 (FIGS. 6A and 6B), the pressing portion 5 is a movable frame when moving. The lower end portion 41 of the skirt 4 of 3 and the bottom surface 213 of the mounting portion 31 of the fixed frame 3 can be smoothly moved without being caught.

In the present embodiment, the skirt 4 is configured to be detachable from the movable frame 3 as a separate component separated from the movable frame 3.

In the present embodiment, the skirt 4 has a downward U-shape in cross-sectional view, and the vicinity of the lower end portion 41a of the skirt 4a is slidably contacted with the lower surface of the movable frame 3 to prevent separation from the slide portion 32. Horizontal ribs 42 are provided so as to face inward. The skirt 4 of the present embodiment can be easily slidably mounted on the slide portion 31 by sliding and inserting the skirt 4 into the slide portion 31 of the movable frame 3 from the lateral direction. Further, if the skirt 4 is provided with a predetermined lower end portion 41, high rigidity unlike the movable frame 3 is not required. Therefore, the skirt 4 in which the shape is important is separated from the movable frame 3 in which the strength is important. As a result, it is possible to suppress the use of excess material and efficiently manufacture the material.

In the present embodiment, since the length of the skirt 4 along the slide direction of the movable frame 3 is constant, the fixed frame 2 of the bathtub handrail 1 is opposite to the side surface of the bathtub side wall pressed by the pressing portion 5. It has an abutting portion 23 that comes into contact with the other side surface of the side, and a notch 7 that can accept the skirt 4 in the sliding direction (FIGS. 2 and 3).

In the bathtub handrail 1 of the present embodiment, in the fixed frame 2 directly placed on the upper surface of the bathtub side wall, the contact portion 23 is attached to the contact base portion 22 constituting the vertical portion (vertical member) of the fixed frame 2. Therefore, even if the pressing portion 5 attached to the movable frame 3 is pressed from the side opposite to the contact portion 23 with the bathtub side wall sandwiched between them, the position is displaced between the fixed frame 2 and the upper surface of the bathtub side wall. It can be firmly attached to the side wall of the bathtub by the clamping force of the contact portion 23 and the pressing portion 5 without generating stress (friction force).

Further, as described above, the bathtub handrail 1 of the present embodiment slides the rib of the skirt 4 provided with the predetermined lower end portion 41 to the mounting portion 21 constituting the horizontal portion (horizontal member) of the fixed frame 2. Since it has a notch 7 that can be accepted in the direction, the movable frame 3 does not interfere with the fixed frame 2 even if the length of the movable frame 3 of the skirt 4 in the sliding direction does not change. Can be freely brought close to and separated from the fixed frame 2. Two notches 7 are opened from the tip edge portion of the mounting portion 21 to the vicinity of the central portion in the sliding direction of the movable frame 3, and two notches 7 are formed according to the positions of the ribs of the skirt 4 having the lower end portion 41. There is.

In the absence of the skirt 4, when the movable frame 3 is fixed at the position farthest from the fixed frame 2, the lower surface of the slide portion 31 of the movable frame 3 is overlapped with the end of the mounting portion 21 of the fixed frame 2. A step (not shown) is formed. However, in the bathtub handrail 1 of the present embodiment, the bottom surface of the slide portion 31 of the movable frame 3 is the mounting portion 21 of the fixed frame 2 via the lower end portion 41 of the skirt 4 within the range in which the pressing portion 5 moves. Since it is connected to substantially the same level as the bottom surface 213 of the above, smooth movement of the pressing portion 5 between the movable frame 3 and the fixed frame 2 is guaranteed without causing catching (FIGS. 5 (b), FIG. 6 (a)).

On the other hand, when the fixed frame 2 is not provided with the notch 7, when the movable frame 3 is fixed at the position closest to the fixed frame 2, the rib of the skirt 4 having the lower end 41 is formed on the fixed frame 2. It interferes with the mounting portion 21, and the movable frame 3 cannot be brought close to the fixed frame 2 below the length of the skirt 4. However, in the bathtub handrail 1 of the present embodiment, since the notch 7 for receiving the rib of the skirt 4 in the slide direction is provided in the mounting portion 21 of the fixed frame 2, the rib of the skirt 4 is fixed to the frame. Most of the slide portion 31 of the movable frame 3 can be brought close to the mounting portion 21 of the fixed frame 2 so as to overlap with each other without interfering with the mounting portion 21 of the movable frame 3 (see FIG. 5C).

Further, in the bathtub handrail 1 of the present embodiment, even when most of the slide portion 31 of the movable frame 3 overlaps with the mounting portion 21 of the fixed frame 2, the lower end portion 41 of the skirt 4 is notched in the fixed frame 2. Since it is held at substantially the same level as the bottom surface 213 of the mounting portion 21 in 7, the movable frame 3 can be moved without being caught in the same manner as when the movable frame 3 is fixed at the position farthest from the fixed frame 2. Smooth movement of the pressing portion 5 between the frame 3 and the fixed frame 2 is guaranteed (see FIG. 6B).

FIG. 7 shows an exploded view of the fixed frame 2 of the bathtub handrail 1 of the present embodiment shown in FIG.

The fixed frame 2 of the present embodiment is provided with a mounting portion 21 mounted on the upper surface of the bathtub side wall and a contact portion 23 connected to the mounting portion 21 and abutted against one side surface of the bathtub side wall. It is composed of a contact base 22, and a grip support accommodating portion 29 for slidably accommodating a pair of grip support portions 242 of the main grip 24 is provided on the back surface of the abut base portion 22. There is. Further, in order to fix the grip support portion 242 of the main grip 24 without rattling on the upper portion of the grip support portion accommodating portion 29, a tapered diameter-reduced portion 290 and a thread of the reduced-diameter portion 290 are screwed together. A nut 291 is provided.

The mounting portion 21 of the fixed frame 2 has two reinforcing ribs 20 that extend continuously from the mounting portion 21 to the contact base portion 22 and, in the width direction of the mounting portion 21, more than the grip support portion 242. An extension 28 extending outward is provided. Further, in order to screw the movable frame 3 to the mounting portion 21 in a variable mounting position, a plurality of fixing screw holes 211 arranged at equal pitches along the slide direction of the movable frame 3 and fixing screws A pair of guide screw holes 212 are provided in a direction orthogonal to the arrangement direction of the holes 211 and arranged at positions symmetrical with respect to the arrangement of the fixing screw holes 211.

Elastic resin rubbers 210 and 230 that prevent damage to the side wall of the bathtub and prevent slipping are attached to the inner surface (back side) of the mounting portion 21 of the fixed frame 2 and the inner surface of the contact portion 23, respectively. Further, on the inner surface of the contact base 22 and below the contact portion 23, a guide portion 231 for preventing the contact portion 23 from riding on the upper surface of the bathtub side wall when the bathtub handrail 1 is attached is provided. It is attached. In this embodiment, the contact portion 23 and the guide portion 231 are made of resin.

FIG. 8 shows a state in which the movable frame 3 of the bathtub handrail 1 of the present embodiment shown in FIG. 1 is disassembled into a frame main body 3, a moving device 6 (including a torque transmission / blocking means 64), and a pressing portion 5. Is outlined.

As shown in FIG. 8, in the bathtub handrail 1 of the present embodiment, the pressing portion 5 includes a resin rubber 51, and the resin rubber 51 has a circular convex portion 510 provided on the back surface thereof. It is attached by fitting it into the circular recess 500 of the pressing portion main body 50.

Further, the pressing portion main body 50 is provided with a fixing hole 501 that fits with the tip portion of the bolt 63, the tip portion of the bolt 63 is inserted into the fixing hole 501, and the screw 502 is used from the side where the tip portion is exposed. By stopping, the pressing portion 5 is attached to the tip end portion of the bolt 63. In this embodiment, since the pressing portion main body 50 is provided with a play at the attachment portion of the bolt 63 to the tip portion, the pressing portion main body 50 can swing its head with respect to the tip portion of the bolt 63. Therefore, the pressing portion 5 of the present embodiment can reliably press against the side wall of the bathtub having a curved surface.

In the bath rail 1 of the present embodiment, the moving device 6 for advancing and retracting the pressing portion 5 toward the contact portion 23 is a nut 61 rotatably attached to the vertical portion 32 of the movable frame 3. It is composed of a handle knob 62 for rotating the nut 61, and a bolt 63 whose tip is connected to the pressing portion 5 and screwed into the nut 61, and the handle is further less than a predetermined force. It includes a torque transmission / shutoff means 64 that transmits the turning power from the knob 62 to the nut 61 and cuts off the transmission of the turning power from the handle knob 62 to the nut 61 at a predetermined force or more.

In the present embodiment, since the moving device 6 is composed of the nut 61 and the bolt 63, the pressing portion 5 can be easily brought close to or separated from the abutting portion 23 by screwing back and forth of the bolt 63, and further The state can be reliably maintained. Further, in the present embodiment, the nut 61 is rotatably attached to the vertical portion 32 of the movable frame 3, and the pressing portion 5 attached to the bolt 63 and its tip by rotating the nut 61 with the handle knob 62. Is screwed back and forth, so that the position of the handle knob 62 does not change with respect to the vertical portion 32. As a result, in the present embodiment, it is possible to prevent the handle knob 62 from protruding from the bathtub handrail 1, which is safe for the user.

Further, since the moving device 6 of the present embodiment includes the torque transmitting / blocking means 64, even if the user turns the handle knob 62 and strongly pushes the pressing portion 5 toward the abutting portion 23, the side wall of the bathtub is damaged. The bathtub handrail 1 of the present embodiment is required and can be attached to the side wall of the bathtub with sufficient pressing pressure (clamping force). Further, even if the above-mentioned torque transmission / blocking means 64 is provided in the moving device 6 of the pressing portion 5, the position of the handle knob 62 does not change with respect to the vertical portion 32 of the movable frame 3.

The torque transmission / shutoff means 64 of the present embodiment includes a substantially circular torque transmission surface 650 orthogonal to the rotation axis of the handle knob 62, and is synchronized with the rotation of the handle knob 62 and the rotation of the handle knob 62. A second annular member 66 having an annular member 65 slidably mounted along the axis and a substantially circular torque transmitting surface 660 that abuts the torque transmitting surface 650 and is orthogonal to the rotation axis of the nut 61. A nut 61 having a flange 610 and a urging means 67 for urging the torque transmission surface 650 of the annular member 65 toward the torque transmission surface 660 of the nut 81, and the torque transmission surface 650. And the torque transmission surface 660 locks the torque transmission surface 650 and the torque transmission surface 660 with each other when the rotational force transmitted to each of them is less than a predetermined force, and the rotational force transmitted is equal to or more than a predetermined force. Is configured by including a recess or a convex portion having an inclined surface that causes slippage between the torque transmitting surface 650 and the torque transmitting surface 660.

The center of the torque transmission surface 650 and the center of the torque transmission surface 660 of the torque transmission / cutoff means 64 are arranged coaxially with the rotation axes of the handle knob 62 and the nut 61. Further, on the torque transmission surface 650 and the torque transmission surface 660, concave / convex portions including a slope inclined from the torque transmission surface 650 or the torque transmission surface 660 are formed, respectively. The inclined surface of the torque transmission surface 650 and the inclined surface of the torque transmitting surface 660 are inclined so as to rise on the opposite inclined surfaces facing each other when the handle knob 62 is turned so as to push the pressing portion 5 into the side wall of the bathtub. Has been done.

The annular member 65 having the torque transmission surface 650 is slidably mounted along the rotation axis of the handle knob 62 and the nut 61, and is attached toward the torque transmission surface 660 by the elastic body urging means 67. It is being pushed. The urging means 67 is not particularly limited as long as it can be elastically deformed, such as a coil spring, a disc spring, and an elastic resin material, and known ones can be used.

Therefore, a constant frictional force is always generated between the inclined surface of the torque transmission surface 650 and the inclined surface of the torque transmission surface 660. When the torque transmitted from the handle knob 62 to the nut 61 is less than a predetermined value, the inclined surface of the torque transmission surface 650 cannot overcome the inclined surface of the torque transmission surface 660 and engages with each other in a state of being meshed with each other. It fits. Then, by this engagement, the torque of the handle knob 62 is transmitted to the nut 61, and the bolt 63 screwed with the nut 61 presses the pressing portion 5 attached to the movable frame 3 toward the side wall of the bathtub.

On the other hand, when the torque transmitted from the handle knob 62 to the nut 61 becomes a predetermined value or more, the inclined surface of the torque transmission surface 650 slips with the inclined surface of the torque transmission surface 660. As a result, the annular member 65 provided with the torque transmission surface 650 retracts against the urging means 67, and the inclined surface of the torque transmitting surface 650 gets over the inclined surface of the torque transmitting surface 660, so that the two are engaged with each other. It will be released. Therefore, even if the handle knob 62 is turned in this state, the handle knob 62 only idles with respect to the nut 61, and torque is not transmitted from the handle knob 62 to the nut 61.

Further, a vertical surface substantially orthogonal to the torque transmission surface 650 is formed at the rear end of the inclined surface of the torque transmission surface 650, and the torque transmission surface 660 is approximately formed at the rear end of the inclined surface of the torque transmission surface 660. Orthogonal vertical planes are formed. The vertical surface of the torque transmission surface 650 and the vertical surface of the torque transmission surface 660 come into contact with each other and engage with each other when the handle knob 62 is turned so as to separate the pressing portion 5 of the movable frame 3 from the side wall of the bathtub. Therefore, when the handle knob 62 is rotated so as to separate the pressing portion 5 from the side wall of the bathtub, the handle knob 62 and the nut 61 always rotate in synchronization with each other regardless of the magnitude of the transmitted torque.

As described above, in the torque transmission / shutoff means 64, the torque transmission surface 660 that rotates in synchronization with the rotation of the nut 61 is attached to the outer peripheral surface of the nut 61. Therefore, since the torque transmission / cutoff means 64 can be partially overlapped with the nut 61 main body, the torque transmission / cutoff means 64 and the movable frame of the handle knob 62 provided with the torque transmission / cutoff means 64 are provided. The protrusion length from 3 can be suppressed.

Further, in the present embodiment, in order to improve the maintainability of the torque transmitting / blocking means 64 by facilitating the replacement of consumable parts, the torque transmitting surface 660 is synchronized with the rotation of the nut 61. It is formed on a second annular member 66 that is detachably attached to.

Further, in order to improve the maintainability of the torque transmission / blocking means 64 by facilitating the attachment / detachment of the nut 61 to / from the vertical portion 32 of the movable frame 3, the nut 61 is provided on the vertical portion 32 of the movable frame 3. A body portion 612 to be inserted through the opening 314 is provided, and the outer diameter of the second annular member 66 is set to an outer diameter larger than that of the opening 314. From the side surface opposite to the side surface of the vertical portion 32 with which the second annular member 66 abuts, the flange member 69 having an outer diameter larger than the opening 314 and the cover 690 are connected to the second annular member 66 by a screw 691. As a result, the nut 81 can be rotatably attached to the vertical portion 32.

Further, in order to prevent the second annular member 85 and the flange member 69 from being worn and to facilitate the rotation of the nut 61, the vertical portion 32 of the movable frame 3 is provided with the second annular member 66 via a resin washer 68. And is sandwiched by the flange member 69.

Further, in the present embodiment, the end portion of the body portion of the handle knob 62 is provided with a diameter-expanded portion 621 having a diameter larger than that of the body portion. The handle knob 62 is rotated in synchronization with the annular member 65 having the torque transmission surface 650, and the upper and lower handle fixing cover 622 has an opening having an inner diameter smaller than that of the enlarged diameter portion 621 so as not to be separated from the nut 61. It is rotatably attached to the vertical portion 32 of the movable frame 3 by.

In the torque transmission / blocking means 64 of the present embodiment, the first locking means 623, which is provided inside the handle knob 62 and is formed of a protrusion or the like formed between the protrusions, and the nut 61 By connecting the second locking means 611, which is a recess such as a notch provided at the end, with an engaging means (not shown) such as a pin, the handle knob 62 to the nut 61 are always connected even if a predetermined force or more is applied. It is possible to transmit the turning power to the nut.

As will be well understood with reference to FIGS. 9, 10, 14 and 15, the bathtub handrail 1a of the second embodiment (including the bathtub handrail 1b of the third embodiment described later) is the first. With respect to the bathtub railing 1 of the first embodiment, the skirt 4a is divided into a plurality of short length divided skirts 40a so that the total length thereof can be freely adjusted, and the entire skirt 4a. Since the length of the fixed frame 2a can be adjusted, the mounting portion 21a of the fixed frame 2a is different only in that the notch for receiving the skirt 4a attached to the slide portion 31 of the movable frame 3 is not provided. The configurations of the above are all the same as the configurations of the bathtub handrail 1 of the first embodiment.

Therefore, the bathtub handrail 1a of the second embodiment will be described in detail mainly in a configuration different from that of the bathtub handrail 1 of the first embodiment, and the bathtub handrail 1a of the other first embodiment will be described in detail.

Further, in the present embodiment, even if the mounting position of the movable frame 3 with respect to the fixed frame 2a, in other words, the separation distance between the contact base portion 22a of the fixed frame 2a and the vertical portion 32a of the movable frame 3 is changed, the fixed frame Adjusting the length of the entire skirt 4a (connecting body of the split skirt 40a) to be attached to the slide portion 31 according to the length of the slide portion 31 of the movable frame 3 protruding from the upper surface of the mounting portion 21a of 2a. Can be done. Therefore, no matter how the mounting position of the movable frame 3 with respect to the fixed frame 2a is changed, the length of the skirt 4a can be freely adjusted so as not to interfere with the contact base 22a of the fixed frame 2a. The placement portion 21a is not provided with a notch for receiving the skirt 4a in the slide direction, and is omitted.

The skirt 4a of the present embodiment is configured as a separate part separated from the movable frame 3, and one split skirt 40a constituting the skirt 4a is the movable frame 3 of the skirt 4 of the first embodiment described above. It is divided into about one-third the length of the slide direction. In the present embodiment, since a plurality of the above-mentioned short length divided skirts 40a are prepared, the length of the entire skirt 4a can be adjusted by adjusting the number of the divided skirts 40a to be attached to the slide portion 31 of the movable frame 3. Can be adjusted.

Further, the split skirt 40a of the present embodiment has a downward U-shape, and the vicinity of the lower end portion 41a of the split skirt 40a is slidably contacted with the lower surface of the movable frame 3 to prevent separation from the slide portion 32. The horizontal rib 42a is provided so as to face inward. Therefore, the divided skirt 40a and the skirt 4a which is an aggregate thereof can be easily attached to and detached from the slide portion 32 by sliding and inserting the split skirt 40a and the skirt 4a which is an aggregate thereof from the lateral direction into the slide portion 32 of the movable frame 3.

In the present embodiment, the length of the split skirt 40a along the slide direction of the movable frame 3 is arbitrary and is not particularly limited, but the shorter the length of the split skirt 40a, the finer the length of the entire skirt 4a is adjusted. can do. For example, in the case of a type in which the slide portion 32 of the movable frame 3 is fixed to the mounting portion 21a of the fixed frame 2a by screwing as in the present embodiment, at least one type of length of the split skirt 40a is screwed. The split skirt 40a has a length equal to or less than the pitch of the fixing screw holes 211a (or through holes 311) used for fixing screw holes 211a (or through holes 311), and further has a length equal to or less than the pitch of the fixing screw holes 211a (or through holes 311). Is more preferable if is prepared. Further, if a plurality of divided skirts 40a having different lengths are prepared, the length of the entire skirt 4a can be adjusted in a wider range and finely.

In the case of the handrail 1a for a bathtub in which the movable frame 3 is mounted on the fixed frame 2a as in the present embodiment, when the movable frame 3 is fixed at the position farthest from the fixed frame 2a, the movable frame 3 A step is formed on the lower surface of the slide portion 31 constituting the horizontal portion (horizontal member) of the above by the end portion of the mounting portion 21a of the overlapping fixed frame 2a. However, in the case of the present embodiment, by mounting the above-mentioned split skirt 40a in the entire area of the slide portion 31 in the range in which the pressing portion 5 moves, the lower end portion of the region in which the split skirt 40a of the slide portion 31 is mounted is mounted. Since the 41a is connected to substantially the same level as the bottom surface 213a of the mounting portion 21a of the fixed frame 2a, smooth movement of the pressing portion between the movable frame 3 and the fixed frame 2a is guaranteed without causing catching. (See FIGS. 12 (b) and 13 (a)).

On the other hand, when the movable frame 3 is fixed at the position closest to the fixed frame 2a, the rib of the skirt 4a provided with the lower end portion 41a interferes with the mounting portion 21a of the fixed frame 2a, and the movable frame 3 Cannot be brought close to the fixed frame 2a below the length of the skirt 4a. However, in the case of the present embodiment, the skirt 4a is further divided into a plurality of shorter divided skirts 40a, and the length of the entire skirt 4a is adjusted by adjusting the number of the divided skirts 40a attached to the slide portion 31 of the movable frame 3. Since the ribs of the split skirt 40a can be freely adjusted, most of the slide portion 31 of the movable frame 3 is close to the mounting portion 21a of the fixed frame 2a without interfering with the mounting portion 21a of the fixed frame 2a. (See FIG. 12 (c)).

In the case of the present embodiment, when the movable frame 3 is fixed at the position closest to the fixed frame 2a, it is attached to the slide portion 31 as shown in FIGS. 12 (c) and 13 (b). The attachment of the split skirt 40a is omitted.

Further, the slide portion 31 of the movable frame 3 protruding from the mounting portion 21a of the fixed frame 2a can be attached with an arbitrary length and number of divided skirts 40a according to the range in which the pressing portion 5 moves. As a result of the lower end portion 41a of the region where the split skirt 40a of the slide portion 31 is mounted is held at substantially the same level as the bottom surface 213a of the mounting portion 21a of the fixed frame 2a, the movable frame 3 is most separated from the fixed frame 2a. As in the case of fixing to the fixed position, smooth movement of the pressing portion 5 between the movable frame 3 and the fixed frame 2a is guaranteed without causing catching (see FIG. 13 (b)).

Therefore, the bathtub handrail 1b of the third embodiment will be described in detail mainly in a configuration different from that of the bathtub handrails 1 and 1a of the first and second embodiments. The description of the same configuration as the bathtub handrails 1, 1a of the second embodiment will be omitted. Further, among the components of the bathtub handrail 1b according to the third embodiment, the same components as the bathtub handrails 1 and 1a of the first and second embodiments are, in principle, the first and second components. It will be described by using the same reference numerals as those of the bathtub handrails 1, 1a of the above embodiment.

As shown in FIGS. 9, 10 and 14, the basic skeleton of the bathtub handrail 1b of the present embodiment is the same as that of the bathtub handrails 1, 1a of the first and second embodiments, and the bathtub. An inverted L-shaped fixed frame 2a including a mounting portion 21a that is directly mounted on the upper surface of the side wall and a contact base 22a that is connected to the mounting portion 21a and is in contact with one side surface of the side wall of the bathtub. A tilted portion 31 provided with a slide portion 31 slidably mounted on the mounting portion 21a of the fixed frame 2a, and a vertical portion 32 connected to the slide portion 31 and abutted on another side surface of the bathtub side wall. It is composed of an L-shaped movable frame 3. Further, a skirt 4b having a lower end portion 41b that is substantially the same level as the bottom surface of the mounting portion 21a of the fixed frame 2a when the movable frame 3 is attached to the fixed frame 2a is attached to and detached from the slide portion 31 of the movable frame 3. It is attached freely.

As shown in FIGS. 10 and 14, the fixed frame 2a of the present embodiment is continuous from the mounting portion 21a to the contact base portion 22 as in the bathtub handrail 1 according to the first embodiment. The two reinforcing ribs 20a extending in the width direction of the mounting portion 21a and the extending portion 28a extending outward from the grip support portion 242 in the width direction of the mounting portion 21a are provided, but the sliding portion of the movable frame 3 The notch 7 for receiving the skirt 4b attached to the 31 is not provided.

As shown in FIG. 15, the movable frame 3 of the present embodiment has a short length that can be flipped up and closed so that the vertical rib having the lower end portion 41b of the skirt 4b can freely adjust its length. It has the same configuration as the bathtub handrails 1 and 1a of the first and second embodiments except that it is divided into ribs 40b. Therefore, the pressing portion 5 of the present embodiment is moved by turning the nut 61 of the moving device 6 including the nut 61 and the bolt 63, so that the bolt screwed with the nut 61 is screwed back and forth. Further, the moving device 6 includes a torque transmission / shutoff means 64, and the nut 61 is rotated by the handle knob 62 via the torque transmission / shutoff means 64.

In FIG. 16, in the bathtub handrail 1b of the third embodiment, the fixed frame 2a and the movable frame 3 are (a) separated, (b) separated and connected, and (c) closely connected. A schematic diagram of each is shown, and FIG. 17 shows a state in which the fixed frame 2a and the movable frame 3 are (a) separated and connected in the bathtub handrail 1b of the third embodiment shown in FIG. And (b) side views of each of the close-coupled states are shown.

The skirt 4b of the present embodiment opens and closes the vertical rib having the lower end portion 41 of the skirt 4 described in the first embodiment, which has a short length along the sliding direction of the movable frame 3 and can be individually flipped up. By dividing into the ribs 40b, the length of the entire vertical rib having the lower end portion 41b of the skirt 4b can be adjusted by adjusting the number of opening and closing ribs 40b. Therefore, the opening / closing rib 40b of the skirt 4b is arranged above the mounting portion 21a of the fixed frame 2a when it is flipped up (opened) with the movable frame 3 attached to the fixed frame 2a, and when it is closed. Is arranged so that the lower end portion 41b of the opening / closing rib 40b is at substantially the same level as the bottom surface 213a of the mounting portion 21a of the fixed frame 2a.

In the present embodiment, each of the opening / closing ribs 40b of the skirt 4b is attached to the horizontal portion of the skirt 4b via a rotating means such as a hinge, and is along a plane orthogonal to the sliding direction of the movable frame 3. Can be flipped up.

In the present embodiment, even if the mounting position of the movable frame 3 with respect to the fixed frame 2a, in other words, the separation distance between the contact base portion 22a of the fixed frame 2a and the vertical portion 32a of the movable frame 3 is changed, the fixed frame 2a The opening / closing rib 40b of the skirt 4b is closed and the remaining opening / closing rib 40b is opened (jumped up) according to the length of the slide portion 31 of the movable frame 3 protruding from the upper surface of the mounting portion 21a. By doing so, the length of the entire vertical rib forming the lower end portion 41b of the skirt 4b can be adjusted.

Therefore, in the present embodiment, the vertical rib length of the skirt 4b can be freely adjusted so as not to interfere with the contact base 22a of the fixed frame 2a no matter how the mounting position of the movable frame 3 with respect to the fixed frame 2a is changed. Therefore, the mounting portion 21a of the fixed frame 2a is not provided with a notch for receiving the vertical rib of the skirt 4b in the sliding direction, and is omitted.

The skirt 4b of the present embodiment is configured as a separate part separated from the movable frame 3, and the opening / closing rib (split skirt) 40b of the skirt 4b is the movable frame 3 of the skirt 4 of the first embodiment described above. It is divided into about one-third the length of the slide direction. In the present embodiment, the length of the entire vertical rib forming the lower end portion 41b of the skirt 4b can be adjusted by adjusting the closed state and the open (jumped up) state of the opening / closing rib 40b.

Further, in the present embodiment, the skirt 4b provided with the opening / closing rib (split skirt) 40b has a downward U-shape or a C-shape. Therefore, the skirt 4b can be easily attached to and detached from the slide portion 32 by inserting the skirt 4b into the slide portion 32 of the movable frame 3 from the lateral direction.

In the present embodiment, the length of the opening / closing rib (split skirt) 40b of the skirt 4b along the sliding direction of the movable frame 3 is arbitrary and is not particularly limited, but if the length of the opening / closing rib (split skirt) 40b is short, The shorter the length, the finer the length of the entire vertical rib of the skirt 4b can be adjusted. For example, in the case of a type in which the slide portion 32 of the movable frame 3 is fixed to the mounting portion 21a of the fixed frame 2a by screwing as in the present embodiment, the length of the opening / closing rib (split skirt) 40b is at least 1. The type is preferably the same length as the pitch of the fixing screw hole 211a (or through hole 311) used for screwing, and further, the length is equal to or less than the pitch of the fixing screw hole 211a (or through hole 311). It is more preferable that the opening / closing rib (split skirt) 40b having the opening / closing rib (split skirt) 40b is prepared.

In the case of the bathtub handrail 1b in which the movable frame 3 is mounted on the fixed frame 2a as in the present embodiment, when the movable frame 3 is fixed at the position farthest from the fixed frame 2a, the movable frame is used. A step is formed on the lower surface of the slide portion 31 forming the horizontal portion (horizontal member) of No. 3 by the end portion of the mounting portion 21a of the overlapping fixed frame 2a. However, in the case of the present embodiment, of the skirt 4b attached to the slide portion 31, only the split ribs in the range where the slide portion 31 is arranged above the mounting portion 21a of the fixed frame 2a are flipped up, and the fixed frame 2a By tilting only the opening / closing rib (split skirt) 40b in the range where the pressing portion 5 moves other than the mounting portion 21a, the lower end of the region where the opening / closing rib (split skirt) 40b of the sliding portion 31 is tilted downward. Since the portion 41b is connected to substantially the same level as the bottom surface 213a of the mounting portion 21 of the fixed frame 2a, the pressing portion 5 can be smoothly moved between the movable frame 3 and the fixed frame 2a without being caught. Guaranteed (see FIGS. 16 (b) and 17 (a)).

On the other hand, when the movable frame 3 is fixed at the position closest to the fixed frame 2a, the opening / closing rib (split skirt) 40b of the skirt 4b provided with the lower end portion 41b interferes with the mounting portion 21a of the fixed frame 2a. Therefore, the movable frame 3 cannot be brought close to the fixed frame 2a below the length of the skirt 4b. However, in the case of the present embodiment, the slide out of the opening / closing ribs (split skirts) 40b of the skirt 4b attached to the slide portion 31 is the same as in the case where the movable frame 3 is fixed at the position farthest from the fixed frame 2a. Only the opening / closing rib (split skirt) 40b in the range where the portion 31 is arranged above the mounting portion 21a of the fixed frame 2a is flipped up, and the opening / closing of the range in which the pressing portion 5 moves other than the mounting portion 21a of the fixed frame 2a. By tilting only the rib (split skirt) 40b downward, most of the slide portion 31 of the movable frame 3 is fixed without causing the opening / closing rib (split skirt) 40b of the skirt 4b to interfere with the mounting portion 21a of the fixed frame 2a. It can be brought close to the frame 2a so as to overlap with the mounting portion 21a (see FIG. 16C).

In the case of the present embodiment, when the movable frame 3 is fixed at the position closest to the fixed frame 2a, it is attached to the slide portion 31 as shown in FIGS. 16 (c) and 17 (b). The opening / closing ribs (split skirts) 40b of the skirt 4b are all flipped up on the mounting portion 21a of the fixed frame 2a.

Further, the slide portion 31 of the movable frame 3 protruding from the mounting portion 21a of the fixed frame 2a has an opening / closing rib (split skirt) 40b adjusted to an arbitrary length according to the range in which the pressing portion 5 moves. Since 4b can be attached, the lower end portion 41b of the area where the skirt 4b of the slide portion 31 is attached is held at substantially the same level as the bottom surface 213a of the mounting portion 21a of the fixed frame 2a, and as a result, the movable frame 3 is fixed. As in the case of fixing at the position farthest from the frame 2a, smooth movement of the pressing portion 5 between the movable frame 3 and the fixed frame 2a is guaranteed without causing catching (FIG. 17 (FIG. 17). b) See).

4. In the bathtub handrails 1, 1a, 1b of the other first, second, and third embodiments, as described above, the pressing portion 5 movably attached to the movable frame 3 is the end of the fixed frame 2, 2a. The purpose is to prevent catching on a step formed on the lower surface of the movable frame 3 by the portion. Therefore, as a means of moving the pressing portion 5 of the type that can most enjoy the benefit according to the present embodiment, there is a means of rotating either the bolt or the nut and screwing it back and forth while transmitting the rotational power to the bolt. ..

More specifically, as in the present embodiment, the bolt 63 that supports the pressing portion 5 and the vertical portion 32 that is screwed with the bolt 63 and constitutes the vertical member of the movable frame 3 are rotatably attached. A moving device 6 including a nut 61 and a handle knob 62 for rotating the nut 61, or a bolt that supports a pressing portion as described in Patent Document 1, is screwed with the bolt. A moving device including a nut that is non-rotatably fixed to a vertical portion constituting a vertical member of the movable frame and a handle knob for rotating a bolt is a skirt 4, 4a, 4b according to the present embodiment. And the type of transportation that can most benefit from the application of the notch 7 or the split skirts 40a, 40b.

Further, in the bathtub handrails 1, 1a and 1b of the first, second and third embodiments, the fixed frames 2 and 2a having an inverted L shape in the side view are directly placed on the side wall of the bathtub and fixed. By mounting the movable frame 3 having an inverted L shape on the mounting portions 21 and 21a constituting the horizontal members of the frames 2 and 2a, the pressing portion 5 attached to the movable frame 3 is attached to the side wall of the bathtub. Even when pressed, it is firmly attached to the side wall of the bathtub by the clamping force of the contact portions 23, 23a and the pressing portion 5 without causing a positional shift or stress (friction force) between the fixed frames 2, 2a and the upper surface of the side wall of the bathtub. It is characterized by being able to do it.

Therefore, in the present embodiment, in order to make the best use of the above features, the main grip 24 arranged above the side wall for the bathtub and above the fixed frames 2 and 2a is connected to the upper surface of the side wall of the bathtub. It is attached to the fixed frame 2 and 2a side, which does not cause misalignment or stress (friction force) due to the relationship. Further, in the present embodiment, since the pressing portion 5 and the moving device 6 thereof are attached to the movable frame 3 set on the bathtub side instead of the washing place side, the pressing portion 5 and the bolt 63 supporting the pressing portion 5 are screwed back and forth. The amount of protrusion of the handle knob 62 into the bathtub is suppressed as much as possible. Therefore, in the bathtub handrails 1, 1a and 1b of the first, second and third embodiments, the position of the handle knob 62 with respect to the movable frame 3 even if it is rotated among the two types of moving devices for the pressing portion described above. The former type of mobile device 6 which does not change is adopted.
