Description

The present invention relates to a shaft mounting member that supports a shaft vertically on a mounting surface such as a ceiling surface, and to a suspender and hanging device that use the same.

For example, a hanging device is known in the past that supports a hanger pipe, such as a clothesline pole, approximately horizontally on a shaft that is attached to a target surface such as a ceiling and hangs down. Also known is a sling that has a ring-shaped hanging ring at the end of a shaft that is attached to a target surface and hangs down, and that suspends a hanger or other suitable object to be hung from the ring. One end of the shaft in such hanging devices or slings is attached to the target surface by some kind of mounting member.

In this case, if the shaft is firmly fixed to the mounting member that is fixed to the mounting surface, when an external force is applied from the side to the hanging shaft, load is placed on the mounting surface (such as the ceiling surface) to which it is fixed and on the mounting member, which may accelerate the deterioration of these. Also, since it is best for users to avoid bumping into things as much as possible, they may be very careful to avoid doing so.

In response to this, a technique is known in which a shaft is supported so as to be freely swingable relative to a mounting member that is fixedly attached to the mounting surface (see, for example, Patent Document 1). When a shaft ("hanging rod 5" in Patent Document 1) is hanging down so as to be freely swingable from the mounting surface, if an object to be hung ("dry hanger 11" in Patent Document 1) is hung from the lower end of the shaft or from a hanger pipe supported by the shaft, the shaft (or even the "hanger pipe") will swing and become unstable, making it difficult to perform the hanging operation. In addition, there is a concern that the application of some kind of lateral force to the shaft will cause the object to be hung to swing together with the shaft (or even with the "hanger pipe"), possibly hitting a surrounding wall, window, etc.

Therefore, the present invention has been made in consideration of the above problems. That is, one of the objects of the present invention is to provide a shaft mounting member that allows a shaft supported in a hanging state to tilt diagonally when a load is applied from the side, but that makes it easy to maintain the hanging state of the shaft when there is no load from the side, as well as a sling and hanging device using the same.

The above object can be achieved by the present invention as described below. That is, the shaft mounting member of the present invention is a shaft mounting member for supporting a shaft in a hanging state on a mounting target surface, comprising:
A base to be attached to the mounting surface;
a connecting member fixed to the base, protruding downward, and having a hook portion at a lower end;
a socket having an upper end, a hook portion that hooks onto the hook portion, and a lower end, which supports one end of the shaft;
An annular elastic member is interposed between the base and the socket with the connecting member passing through it.

In the present invention, a ring-shaped pressing surface is formed on the lower surface of the base so as to surround the connecting member,
When the shaft is supported vertically, an annular abutment surface is formed on the upper end of the socket so as to surround the hook portion,

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
Fig. 1 is a front view of a shaft mounting member and a shaft mounted thereon according to an embodiment of the present invention, Fig. 2 is a longitudinal sectional view taken along a plane including a central axis of the shaft mounting member according to an embodiment of the present invention, and Fig. 3 is an exploded longitudinal sectional view of components of the shaft mounting member according to an embodiment of the present invention disassembled in the central axis direction.

In this embodiment, up and down means up and down in the direction of gravity, and "horizontal" or "horizontal plane" means a plane perpendicular to the direction of gravity. However, "horizontal" and "horizontal plane" do not have to be exactly perpendicular to the direction of gravity, and the concept includes not only planes that can be said to be approximately horizontal, but also planes that are somewhat inclined, as long as the inclination is sufficient to realize the present invention.

The shaft mounting member (hereinafter sometimes simply referred to as the "mounting member") 1 of this embodiment supports the shaft 2 in a hanging state on a ceiling surface 3, which is an example of a mounting target surface. Note that in the present invention, the mounting target surface is not limited to a ceiling surface, and may be any horizontal surface facing downward on a member or part capable of supporting a shaft, such as a beam or lintel of a structure, an attic, or the top surface inside furniture.

As shown in Figures 1 to 3, the mounting member 1 in this embodiment specifically comprises a base 11 that is attached to the ceiling surface 3, a bolt (the "connecting member" in this invention) 13 that is fixed to the base 11 and protrudes downward, and a socket 12 that supports one end (upper end) of the shaft 2.

The base 11 has a disk-shaped base 111 and a cylindrical section 112 that rises downward on its center. The base 111 has two screw holes 115 at positions symmetrical about the center, and wood screws (not shown) are passed through these holes and screwed into the ceiling surface 3, fixing and attaching the base 11 to the ceiling surface 3.

A bolt hole 114 with a female screw groove is formed in the center of the base 111. A circular rib 116 protrudes downward from the periphery of the bolt hole 114 in the base 111, and a toric surface 113 (corresponding to the "pressing surface" in the present invention, as described later) is formed between the rib 116 and the cylindrical portion 112 on the underside of the base 11.

A ring-shaped, thick elastic member 14 is housed in the cylindrical portion 112 of the base 11, sandwiched between two washers 15a and 15b. Of these, the uppermost washer 15a fits into an annular groove formed by the rib 116, the annular surface 113, and the cylindrical portion 112, and the upper surface of the washer 15a abuts against the annular surface 113.

The elastic member 14 is preferably made of a material having elasticity, such as natural rubber, synthetic rubber, silicone rubber, or other rubber, or an elastomer, and is formed into a ring shape. However, the elastic member used here may also be, for example, a ring-shaped coil spring or a leaf spring formed into a ring shape.

The socket 12 is located below the base 11. The socket 12 is composed of a cylindrical portion 121 having a downwardly facing insertion hole 126, and an upper end portion 122 located in a position that closes the upper end of the cylindrical portion 121. The upper end portion 122 has an opening 123 at its center that is centered on the central axis X, and the upper end of the cylindrical portion 121 is not completely closed. An upper end surface 127 (corresponding to the "contact surface" in the present invention, as described below) is formed around the opening 123 in the upper end portion 122 (surrounding the opening 123).

The cylindrical portion 121 is further divided into a large outer diameter portion 121 a on the lower side, which has a larger outer diameter, and a small outer diameter portion 121 b, which continues from the large outer diameter portion 121 a and joins to the upper end portion 122 and has a smaller outer diameter.
An inner peripheral surface 121a' having the same diameter as the insertion hole 126 extends upward inside the large outer diameter portion 121a and is connected to a reduced inner diameter surface 121b' that continues to the inside of the small outer diameter portion 121b via a stepped portion 121c'. One end of the shaft 2 is inserted through the insertion hole 126 in the socket 12 and fits into the inner peripheral surface 121a' and stops at the stepped portion 121c'. In other words, this stepped portion 121c' serves as a positioning means for the shaft 2.

The large outer diameter portion 121a of the cylindrical portion 121 has two holes 124a, 124b with female thread grooves formed on the inner circumferential surface. The holes 124a, 124b are drilled toward the shaft 2 to be inserted. Male screws 125a, 125b with male thread grooves that mesh with the female thread grooves formed in the holes 124a, 124b are screwed into the holes 124a, 124b, respectively.

The bolt 13 consists of a shaft 132 with a male thread groove formed therein, and a head 133 that protrudes radially from the shaft 132. The lower end surface of the head 133 is provided with a hexagonal hole 131 into which the tip of a hexagonal wrench fits. In other words, the bolt 13 is called a "hexagonal socket bolt" or an "internal hexagon bolt."

As shown in FIG. 3, the bolt 13 is screwed into the bolt hole 114 with the shaft 132 passing through the washer 16, the opening 123 of the socket 12, the washer 15b, the elastic member 14, and the washer 15a from below in that order. The horizontal diameter of the head 133 and the washer 16 of the bolt 13 is larger than the opening 123 of the socket 12, and the shaft 132 of the bolt 13 is smaller than the opening 123. Therefore, the opening 123 of the socket 12 is configured to hook onto the head 133 and the washer 16 of the bolt 13. Therefore, the opening 123 of the socket 12 corresponds to the hook portion in this invention, and the head 133 and the washer 16 of the bolt 13 correspond to the latch portion.

The male thread formed on the shaft 132 of the bolt 13 is screwed into the female thread formed in the bolt hole 114, and the socket 12 with the opening 123 hooked on the shaft 132 of the bolt 13 is fixed to the base 11. At this time, the elastic member 14 is sandwiched together with the two washers 15a, 15b between the annular surface (pressing surface) 113 formed on the underside of the base 11 and surrounding the bolt 13, and the annular upper end surface (contact surface) 127 formed on the upper end 122 of the socket 12 and surrounding the opening (hook portion) 123.

The bolt 13 is screwed into the bolt hole 114, and the socket 12 is attached to the base 11 with the elastic member 14 sandwiched between them, completing the mounting member 1 of this embodiment. This mounting member 1 is used by fixing the base 11 to a ceiling surface 3 or the like as a mounting target surface, and supporting the shaft 2 in the socket 12.

The head (hook portion) 133 of the bolt 13 is housed in the space inside the reduced inner diameter surface 121b' of the cylindrical portion 121 of the socket 12, so that the upper end portion 24 of the shaft 2, which is later fitted into the inner peripheral surface 121a' of the socket 12, does not interfere with the head 133. The upper end portion 24 of the pipe-shaped shaft 2 is open, and even if the position of the upper end portion 24 overlaps with the position of the head portion 133 of the bolt 13 in the axial direction X, interference can be avoided to a certain extent. Of course, this is not the case when the upper end portion 24 of the shaft 2 is closed.

When one end of the shaft 2 is inserted through the insertion hole 126 in the socket 12 and fitted into the inner circumferential surface 121a', the male screws 125a and 125b are screwed into the holes 124a and 124b, their tips protrude from the inner circumferential surface 121a' and press against the circumferential surface of the shaft 2. The pressing force of the male screws 125a and 125b fixes and supports one end of the shaft 2 in the socket 12.

The shaft 2 has a straight pipe section 21, a constricted section 22 that is recessed and constricted around the entire circumference just before the upper end 24, and a neck section 23 that is connected to the constricted section 22 and has the same diameter as the straight pipe section 21 up to the upper end 24. When the upper end 24 of the shaft 2, which is fitted into the inner circumferential surface 121a' of the socket 12, is positioned by abutting against the step section 121c', the constricted section 22 comes into a position opposite the tip of the male thread 125a.

The tip of the male screw 125a screwed into the hole 124a therefore protrudes into the constricted portion 22 and presses against the shaft 2, firmly fixing the shaft 2 so that it does not move up and down. On the other hand, the tip of the male screw 125b screwed into the hole 124b protrudes against the outer circumferential surface of the straight tube portion 21 of the shaft 2 and presses against and holds down the shaft 2. In other words, the male screw 125a restricts the up and down movement of the shaft 2, while the male screw 125a and the male screw 125b fix and support the entire shaft 2.

Figures 1 and 2 show the mounting member 1 of this embodiment with the shaft 2 attached and supported in a hanging state under normal conditions. For example, when used as a sling or hanging device as described below, a pushing or pulling force is applied in the forward and backward directions when suspending an object, and a lateral external force may act on the shaft 2. The mounting member 1 of this embodiment is capable of tilting diagonally when a load is applied laterally to the shaft 2 supported in a hanging state.

Hereinafter, the operation and effect of this embodiment, which allows the shaft 2 to be inclined obliquely, will be described with reference to FIG.
4A and 4B are longitudinal cross-sectional views showing a state in which a lateral external force acts (a load is applied from the lateral direction) on the shaft 2 attached to the shaft mounting member 1 of this embodiment, where (a) shows a state in which an external force acts from right to left, and (b) shows a state in which an external force acts from left to right.

When an external force acts from right to left, as shown in Figure 4(a), the shaft 2 is pushed to the left and tends to tilt diagonally. The mounting member 1 to which the shaft 2 is fixed also tends to tilt in the same direction as the shaft 2, but the mounting member 1 has an opening 123 in the socket 12 as a hook, and the upper end surface (abutment surface) 127 on the left side of the mounting member 1 protrudes upward from this point, pressing the elastic member 14 via the washer 15a. On the left side of the opening 123, the elastic member 14 compresses itself while pressing the annular surface (pressing surface) 113 on the underside of the base 11 via the washer 15b. The elastic force caused by the compression of the elastic member 14 attenuates the external force from right to left.

Therefore, when an external force acts from right to left, the above action allows the axis of the shaft 2 in this embodiment to tilt obliquely from the axis X in the hanging state to the axis Xa in the tilted state, as shown in Figure 4(a). Therefore, the load from the side is reduced, and the effect thereof can be suppressed.
Then, when the external force acting on the shaft 2 is eliminated and the lateral load is removed, the elastic force of the elastic member 14 causes the elastic member 14 to restore its shape, and the shaft 2 returns to its suspended position on the axis X.

On the other hand, when an external force acts from left to right, the shaft 2 can tilt obliquely in the opposite direction to the case shown in Figure 4(a) above. Although detailed operation is omitted, as shown in Figure 4(b), the upper end face (abutment face) 127 on the right side of the opening 123 protrudes upward, pressing the elastic member 14, compressing it while pressing the annular surface (pressing face) 113 on the underside of the base 11. The elastic force caused by the compression of the elastic member 14 attenuates the external force from left to right.

Therefore, even if an external force is applied from left to right, in this embodiment, the axis of the shaft 2 can be tilted obliquely from the axis X in the hanging state to the axis Xb in the tilted state, as shown in FIG. 4(b), thereby reducing the load from the lateral direction and suppressing its effects.
Then, when the external force acting on the shaft 2 is eliminated and the lateral load is removed, the elastic force of the elastic member 14 causes the elastic member 14 to restore its shape, and the shaft 2 returns to its suspended position on the axis X.

In the explanation of FIG. 4, for convenience, a case where a lateral external force acts from directions that differ by 180° to the left and right (opposite directions) is illustrated as an example, but the present invention is not limited to this. In other words, in the mounting member 1 of this embodiment in which the annular surface 113, the upper end surface (contact surface) 127, the elastic member 14, etc. are annular or circular, the axis of the shaft 2 can tilt obliquely in the same way even if the shaft 2 receives an external force from any lateral direction of 360°.

Therefore, even if a lateral external force acts on the shaft 2, for example, due to a person bumping into it, the axis of the shaft 2 tilts diagonally, mitigating the effect of the external force. Then, after the external force is eliminated and the lateral load is removed, the elastic force of the elastic member 14 causes the shaft 2 to restore its own shape, and the shaft 2 returns to the hanging state.

The angle between the axis X in the hanging state and the axis Xa in the tilted state, i.e., the maximum value of the tilt angle θ of the axis of the shaft 2 (see Figures 4(a) and (b)), is determined by various conditions such as the amount of deformation of the elastic member 14, which is determined by the thickness and elastic force of the elastic member 14, and the margin of the outer diameter of the small outer diameter portion 121b of the socket 12 relative to the size of the inner diameter of the cylindrical portion 112 of the base 11. The maximum value of the tilt angle θ of the axis of the shaft 2 can be increased by increasing the amount of deformation of the elastic member 14 or by increasing the margin of the outer diameter of the small outer diameter portion 121b relative to the size of the inner diameter of the cylindrical portion 112.

By increasing the maximum value of the inclination angle θ of the shaft 2, it is possible to increase resistance to external forces from the side. Increasing the maximum value of the inclination angle θ of the shaft 2 tends to increase the size of the mounting member 1, so it is preferable to design it appropriately within a practical range. There is no preferred range or restriction for the maximum value of the inclination angle θ of the shaft 2, but it is selected from the range of approximately 1° to 20°.

In addition, in this embodiment, the inner diameter of the opening 123, which corresponds to the hook portion of the socket 12, has a tapered shape that gradually increases in diameter from the lower end to the upper end. Therefore, as shown in FIG. 4, even when the entire socket 12 is tilted at an angle, the margin before the inner surface of the opening 123 interferes with the shank portion 132 of the bolt 13 increases, and the maximum value of the inclination angle θ of the axis of the shaft 2 can be increased. There is no limit to the taper angle of the inner surface of the opening 123, but it can be selected from a range of about 1° to 30°, for example.

In the shaft mounting member 1 of this embodiment, the shaft 2 is detachable (can be attached and removed freely). Therefore, by simply preparing the same mounting member 1 (including all cases including attaching the mounting member to the mounting surface in advance, preparing a single mounting member that does not include a shaft in the lineup of products to be sold, and even preparing multiple types of sets of a single mounting member and different types of shafts), it is easy to combine with shafts of different lengths, shapes, etc., or to change them.

The mounting member 1 of the present embodiment described above can itself be used as a hanging device, for example, by attaching a shaft having a ring-shaped hanging ring portion at its lower end or midway to a ceiling surface 3, etc.
Fig. 5 is a front view showing an example of a suspender using the mounting member 1 according to the present embodiment. Fig. 6 is a vertical cross-sectional view taken along a plane including the central axis of the suspender using the mounting member 1 according to the embodiment of the present invention.

As shown in Figures 5 and 6, it has a mounting member 1 and a shaft 2 having one end supported by the mounting member 1, and the other end (lower end) of the shaft 2 is provided with a hanging ring portion 7 for hanging an object, so that it can be used as a hanging device.
The hanging ring part 7 is composed of a cylindrical fixing part 71 and an annular part 72 fixed to the lower end of the cylindrical fixing part 71. The upper part of the fixing part 71 is open, and the lower end of the shaft 2 is inserted and stopped at the closed lower end to be positioned.

The fixing part 71 has two holes 714a, 714b with female thread grooves formed on the inner circumferential surface, similar to the large outer diameter part 121a of the socket 12. The holes 714a, 714b are drilled toward the shaft 2 that is fitted into the fixing part 71. Male screws 715a, 715b with male thread grooves that screw into the female thread grooves formed in the holes 714a, 714b are screwed into the holes 714a, 714b, respectively.

Near the lower end of the shaft 2, a constricted portion 25 is formed that is recessed and narrowed all around, just like near the upper end, and continues to the constricted portion 25 to the lower end to form a neck portion 26 of the same diameter as the straight pipe portion 21. When the lower end of the shaft 2 inserted into the fixing portion 71 is positioned by abutting against the closed lower end, the constricted portion 25 is positioned opposite the tip of the male thread 715a.

In this state, when the male screws 715a and 715b are screwed into the holes 714a and 714b, their tips protrude from the inner circumferential surface of the fixing part 71 and press against the circumferential surface of the shaft 2. The pressing force of the male screws 715a and 715b fixes the fixing part 71 to the lower end of the shaft 2, and the hanging ring part 7 is provided on the shaft 2.

At this time, the tip of the male screw 715a screwed into the hole 714a protrudes and fits into the necked portion 25 of the shaft 2, pressing against the shaft 2 and firmly fixing the fixing portion 71 so that no up and down movement occurs. Meanwhile, the tip of the male screw 715b screwed into the hole 714b protrudes against the outer circumferential surface of the straight tube portion 21 of the shaft 2 and presses against and holds down the shaft 2. In other words, the male screw 715a restricts the up and down movement of the hanging ring portion 7, while the male screw 715a and the male screw 715b fix the entire hanging ring portion 7 to the shaft 2.

The hanging device configured as described above can be used by hanging, for example, a clothes or laundry hanger, or one end of a clothesline pole 8 as shown in FIG. 6, from the annular portion 72 of the hanging ring portion 7 attached to the shaft 2. When using it to hang a clothesline pole 8, another hanging device can be prepared to make a pair, and both ends of the clothesline pole 8 can be hung from the annular portion 72 of the hanging ring portion 7 to bridge the two.

The hanging device in the example of Figures 5 and 6 allows the shaft 2 to tilt diagonally when a lateral external force acts on the object being hung, such as clothing or a clothesline pole 8, or on the shaft 2. Therefore, the entire hanging device bends diagonally relative to the surface to which it is attached, such as the ceiling surface, reducing the lateral load and suppressing its effects.

When the external force is released and the lateral load is removed, the elastic force of the elastic member 14 built into the mounting member 1 restores the shape of the elastic member 14, and the shaft 2 returns to its hanging position. As a result, the entire sling also returns to its normal shape (a shape in which the entire sling is not bent).

In the hanging device shown in the examples of Figures 5 and 6, the hanging ring 7 is provided only at the lower end of the shaft 2, but the hanging device using the shaft mounting member of the present invention is not limited to this. In other words, the hanging ring may be provided at two or more locations in total, at the lower end of the shaft and at one or more intermediate locations, or may be provided only at one or more intermediate locations.

Furthermore, the mounting member 1 according to this embodiment can be used together with the shaft 2 as a component for supporting a hanger pipe as part of a so-called hanging device.
FIG. 7 is a perspective view showing an example of a hanging device 100 using the mounting member 1 according to this embodiment.

7, the hanging device 100 comprises a hanger pipe 5 used for hanging objects, a pair (two pieces) of mounting members 1 according to this embodiment, a pair (two pieces) of shafts 2, one end of which is supported by each mounting member 1, and a pair (two pieces) of joints 4, which support the end of the hanger pipe 5, at the lower end of each shaft 2. The pair of joints 4 support both the left and right ends of the hanger pipe 5 and hold it approximately horizontally.
The pair of mounting members 1, the shaft 2 and the joint 4 are identical in configuration, and therefore, for convenience, one of them will be described below.

The mounting member 1 has a base 11 that is attached to the ceiling surface 3, which is the mounting surface, with wood screws or the like, and one end of the shaft 2 is inserted into the socket 12 to support it. In other words, the mounting member 1 of this embodiment attaches the shaft 2 to the ceiling surface 3 in a hanging state.

There are no particular limitations on the type of joint 4, and examples include a configuration that includes an upward socket portion into which the lower end of the shaft 2 fits, and a horizontal socket portion into which the end of the hanger pipe 5 fits, and that has a means for preventing each from coming loose, such as a screw fastening means.

In the hanging device 100 shown in FIG. 7, the joint 4 is provided only at the lower end of the shaft 2, but this is not limiting. That is, the joint may be provided, for example, midway along the shaft 2 to support the hanger pipe there, or a total of multiple joints may be provided at one or more midway points and at the lower end to support multiple hanger pipes. In this case, the joint provided midway and the joint provided at the lower end have different shapes, structures, etc., and are designed according to their functions.

The hanger pipe 5 is a straight pipe with a generally rectangular cross section and rounded top and bottom surfaces. An object to be hung, such as a flowerpot 6 in the example of Fig. 7, is hung from the hanger pipe 5 and used as a hanging device. The hanger pipe 5 is made of a material such as aluminum or resin.
The peripheral surface of the hanger pipe 5 may be treated with an anti-slip coating to prevent the object to be hung from slipping or falling off.

In the hanging device 100 shown in the example of Figure 7, the hanger pipe 5 is exemplified as one with a roughly rectangular cross section, which is highly aesthetically pleasing and practical, but the hanger pipe may also be a straight pipe with a circular cross section, such as a typical clothesline pole, or even a solid rod that is not tubular (e.g., a wooden rod) (in other words, the concept of "hanger pipe" in this invention includes any object that is faithful to the shape).

According to the hanging device 100 of the example in FIG. 7, when a lateral external force acts on the hanging object such as the flower pot 6, the hanger pipe 5, or the shaft 2, the shaft 2 can tilt at an angle. Therefore, the entire hanging device 100 bends at an angle relative to the mounting point on the ceiling surface 3, reducing the lateral load and suppressing its effects.

When the external force is released and the lateral load is removed, the elastic force of the elastic member 14 built into the mounting member 1 restores the shape of the elastic member 14, and the shaft 2 returns to its hanging position. As a result, the entire hanging device 100 also returns to its normal shape (a shape in which the entire device is not bent).

The shaft mounting member and hanging device using the same of the present invention have been described above with reference to preferred embodiments, but the shaft mounting member and hanging device using the same of the present invention are not limited to the configurations of the above embodiments. For example, in the above embodiment, the shaft 2 is fixed to the mounting member 1 by pressing the circumferential surface of the shaft 2 with two male screws 125a and 125b, but any conventionally known method may be used.

In addition, in the above embodiment, an example is given in which the elastic member 14 is sandwiched between the annular surface (pressure surface) 113 of the base 11 and the upper end surface (contact surface) 127 of the socket 12 together with two washers 15a and 15b, which are other members, but the elastic member interposed between the pressure surface of the base and the contact surface of the socket may be sandwiched directly between them by itself.

In addition, those skilled in the art may modify the shaft mounting member of the present invention, and the sling and hanging device using the same, as appropriate, in accordance with previously known knowledge. As long as such modifications still provide the configuration of the present invention, they are of course included in the scope of the present invention.
