Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame of a sliding door compatible with barrier-free. [0002] When the lower frame of a sliding door is adapted to be barrier-free, the wheel of a wheelchair has no resistance between the indoor floor surface and the outdoor floor surface across the lower frame. The lower frame is formed so that the upper ends of the rails are aligned with the indoor and outdoor floor levels, as shown in Japanese Utility Model Laid-Open No. 3-66384. [0003] Further, in a part such as an entrance or a bathroom, which requires treatment of rainwater or water in a lower frame, a drainage path is formed through the inside of the lower frame, and the accumulation of dirt and dust inside the lower frame becomes a problem. In order to be able to perform cleaning, the lower frame can be divided into a lower frame body located on the lower side and a rail member on which rails are formed, as in Japanese Utility Model Laid-Open No. 3-66384 and Japanese Utility Model Laid-Open No. 6-32671. Will be needed. The lower frame divided into a lower frame main body and a rail member must be connected in a used state.
In the method using a screw like No. 6384, it is necessary to connect at least two places in the same cross section, it takes time and effort to assemble, and it can not be practically separated after being put in use Therefore, internal cleaning is almost impossible. According to the method in which the rail member is snap-fitted to the lower frame main body as disclosed in Japanese Utility Model Application Laid-Open No. Hei 6-32671, the rail member can be easily separated from the lower frame main body. When passing through, the rail member may be deformed by the load and come off the lower frame body. The present invention proposes a lower frame in which, when the lower frame is divided into a lower frame main body and a rail member, the lower frame has good workability, and the rail member does not separate even when the wheelchair passes. In the present invention, the rail member is restrained to the lower frame body by a restraining member straddling between the lower frame body and the rail member, thereby simplifying the connection between the lower frame body and the rail member. Also, the separation of the rail members due to the load of the wheelchair is prevented. The lower frame main body has a prospective piece and a finding piece rising from both sides in the prospective direction, and the rail member has a shape in which a plurality of rails are formed on the prospective piece. The expected width of the rail member is smaller than the distance between the two finding pieces of the lower frame body, and the rail member is placed on the prospective piece of the lower frame body in a state of abutting any one of the finding pieces of the lower frame body. A restraining member straddling the rail member and the lower frame body is sandwiched between the rail member and the finding piece on the opposite side of the finding piece of the lower frame body against which the rail member abuts, and the rail member is held by the lower frame body by the restraining member. Be bound by. With the lower frame body
The rail member has a pinched portion sandwiched between the restraining members.
Each is formed. The restraining member is a lower frame against which the rail member abuts.
Between the locating piece opposite the locating piece of the main body and the rail member
Is arranged in a state sandwiched between the rail member and the locating piece of the lower frame main body, thereby constraining the rail member together with the locating piece of the lower frame main body with which the rail member abuts in the expected direction. In addition, the restraining member
Between the clamped portion overlapping the clamped portion and the clamped portion of the lower frame body.
Holds the holding part that overlaps below and straddles the rail member and the lower frame body.
The holding part is held between the held part of the lower frame body and the rail member.
By sandwiching the portion from above and below, the lifting of the rail member from the lower frame body is restrained. The rail member is placed in a state of being connected to the lower frame body by being restrained from moving in the expected direction and being lifted up by the restraining member. Since the rail member is supported by the lower frame main body by resting on the prospective piece of the lower frame main body, if the movement in the anticipated direction and the lifting with respect to the lower frame main body are restrained by the restraining member, the load on the wheelchair is reduced. Is prevented from coming off from the lower frame main body due to the passage of the wheelchair, and does not come off from the lower frame main body. The restraining member straddles between the rail member and the lower frame main body so as to be linked with each other, and connects the rail member to the lower frame main body together with a finding piece of the lower frame main body against which the rail member abuts.
In order to keep the device in a stable state, it is not necessary to connect at a plurality of locations in the same cross section as in the case of using a screw, so that the number of operations for connection is reduced, and workability and assembly efficiency are improved. Since the restraining member is disposed between the rail member and the locating piece of the lower frame main body, it can be attached and detached even after the lower frame is put in use. In addition to cleaning, replacement when the rail member is damaged can be easily performed. 1 and 2, the present invention is divided into a lower frame main body 2 and a rail member 3 on which a plurality of rails 32 are formed. It is a sliding door lower frame 1 used in a connected state. FIG. 6 shows a case in which the lower frame 1 is used as a sliding door in a bathroom. The lower frame 1 may be used as an entrance door or a terrace door, such as an entrance sliding door or a terrace door, regardless of an object of use as long as the opening uses the sliding door. It is used as a lower frame of sliding doors installed around water. The lower frame main body 2 has a groove-shaped cross-sectional shape from a prospective piece 21 and finding pieces 22 and 23 rising from both sides in the prospective direction, and the prospective piece 21 is drained from one finding piece 22 side to the other finding piece for drainage. Incline downward toward 23. Prospect
The lower level side of 21 has a step, and a prospective piece 24 of a lower level than the prospective piece 21 is formed. Finding 23 is a prospect
Standing up from 24, the prospective piece 24 becomes a drainage channel that collects water from the prospective piece 21 and leads to a drain hole 27 opened in the finding piece 23. When the lower frame 1 is used as a lower frame of a sliding door of a bathroom as shown in FIG. 6, the prospective piece 24 is on the bathroom side, but when it is arranged on the boundary between the room and the outdoor, the prospective piece 24 is on the side. The 24 side is the outdoor side. The rail member 3 is placed on the prospective piece 21 of the lower frame main body 2 while abutting against one of the finding pieces 22 (23) of the lower frame main body 2. Since the restraining member 4 is disposed as described later, the rail member 3 comes into contact with the finding piece 22 on the higher level side of the prospective piece 21 and rests on the prospective piece 21. On the rail member 3 side of the finding piece 22, a holding piece 25 for sandwiching the prospective piece 31 of the rail member 3 together with the prospective piece 21 to prevent the rail member 3 from floating is formed. In the drawing, the portion of the prospective piece 31 sandwiched between the holding pieces 25 is bent so that the upper surfaces of the holding piece 25 and the prospective piece 31 are aligned. The rail member 3 has a shape in which rails 32 for the number of sliding doors arranged in the viewing direction are formed on the upper surface of the viewing piece 31, and the rail 32 is mounted on the viewing piece 21 of the lower frame body 2. In this state, the upper end is formed so as to have the same height as the upper ends of the finding pieces 22 and 23 of the lower frame main body 2. If the distance between the adjacent rails 32, 32 is large enough to cause the wheelchair wheel to fall, a fall stop 35 between the rails 32, 32 to prevent the wheel from falling when the wheelchair passes is provided. It is protruded. The upper end of the drop stopper 35 is aligned with the upper end of the rail 32. The lower surface of the prospective piece 31 abuts against the prospective piece 21 of the lower frame body 2 and is a leg for being supported by the prospective piece 21.
The rail member 3 is prevented from sinking due to the load of the wheelchair by projecting the leg 33 against the projection piece 21 of the lower frame body 2. The prospective piece 31 has a drain hole 34 for allowing water falling thereon to fall on the prospective piece 21 of the lower frame body 2.
Is dawned. The leg portion 33 is formed intermittently in the length direction of the prospective piece 31 as shown in FIG. 5 so as not to block the water dropped on the prospective piece 21. The expected width of the rail member 3 is smaller than the distance between the two finding pieces 22 and 23 of the lower frame main body 2, and the rail member 3 abuts when the rail member 3 is placed on the lower frame main body 2. The lower frame main body 2 is constrained by a constraining member 4 arranged in a space formed between the railing member 3 and the locating piece 23 opposite to the locating piece 22. The restraining member 4 is disposed on the prospective piece 24 of the lower frame body 2 and is sandwiched between the rail member 3 and the finding piece 23 to restrain the rail piece 3 together with the finding piece 22 from moving in the prospective direction. By straddling the member 3 and the lower frame body 2, the lifting of the rail member 3 is restrained. The restraining member 4 of the lower frame body 2 and the rail member 3
The straddled portion 26 sandwiched between the restraining members 4
36 are each formed. Since the restraining member 4 is disposed between the rail member 3 and the finding piece 23, the pinched portion 26 of the lower frame main body 2 is formed so as to project from the lower level side of the prospective piece 21 to the prospective piece 24 side. The held portion 36 is formed at a position parallel to the held portion 26. Finding pieces in drawings
A clamped portion 36 is formed on the leg 33 closer to 23. When the restraining member 4 sandwiches the clamped portions 26 and 36, the leg 33 and the clamped portion 36, which are ends of the rail member 3 on the side of the finding piece 23, abut against the restraining member 4, and the rail member 3 is located on the finding piece 22. Then, the shape is sandwiched between the restraining members 4. As shown in FIG. 1, when the rail member 3 is placed on the lower frame body 2, the constraining member 4
The lower frame body 23 has a vertical cross-sectional shape that can be slid only in the longitudinal direction of the lower frame main body 2. And a holding portion 42 overlapping below the held portion 26 of the lower frame body 2. When the restraining member 4 is inserted from the lower frame main body 2 and the end of the rail member 3, the holding members 41 and 42 are slid as they are so that the holding portions 41 and 42 sandwich the held portions 36 and 26 from above and below. In FIGS. 3 and 4, in order to allow the attachment and detachment of the restraining member 4 even after the connection between the lower frame 1 and the vertical frame is completed, as shown in FIG.
Is cut out, and the restraining member 4 is dropped from above through the notch 37 so as to be mounted or detachable. The restraining member 4 is attached to the lower frame main body 2 by using a screw penetrating the prospective piece 24 and the finding piece 23 of the lower frame main body 2. However, in the drawing, the finding piece 23 is attached to avoid using screws. A projection 28 is formed on the rail member 3 side, and a groove 43 is formed on the surface of the restraining member 4 on the side of the locating piece 23. When the projection 28 enters the groove 43, the restraining member 4 is lowered. It is configured to be fixed to the frame body 2. The protrusion 28 is formed by a protruding process. The restraining member 4 is attached to and detached from the notch 37 of the held portion 36 of the rail member 3, and the upper holding portion 41 overlaps the held portion 36 of the rail member 3 as shown in FIG. In a position where the holding portion 42 of the lower frame body 2 overlaps the held portion 26 of the lower frame body 2, the rail member 3 and the lower frame body 2 are held in a fixed state. It is formed in two places. Correspondingly, the notch 37 of the pinched portion 36 of the rail member 3 is formed over the width of the restraining member 4 when the restraining member 4 is at the attaching / detaching position. After the restraining member 4 is dropped from the notch 37 onto the prospective piece 24, any of the held portions sandwiching the notch 37
As shown in FIG. 3, the projection 28 fits into the groove 43 by being slid to the side 36, and the projection 28 is fixed. However, the stopper 4 locks the restraining member 4 in the sliding direction to limit the amount of movement by sliding. 29 are formed in the held portion 26. The stopper 29 is formed at a fixed position and a detachable position of the restraining member 4. The stopper 29 is also formed by protruding. As shown in FIG. 4, the mounting of the restraining member 4 is performed by aligning the groove 43 with the projection 28 located at the notch 37, and dropping the restraining member 4 from the notch 37, and between the rail member 3 and the finding piece 23. The stopper member 4 is fixed to the lower frame body 2 when the protrusion 28 is fitted into the groove 43 as described above. To remove the restraining member 4, slide it in the reverse direction until it hits the stopper 29,
It is done by withdrawing from. The restraining member 4 has a sliding contact surface which comes into contact with the finding piece 23.
44 slides while sliding on the find piece 23, and the projection 28 fits into the groove 43 by climbing over the sliding contact surface 44, or
The sliding surface 44 is formed in an arc shape on a plane in order to reduce the resistance when the projection 28 is fitted into the groove 43 and when the projection 28 is removed from the groove 43. If the rail member 3 has the same length as the lower frame main body 2, its movement in the longitudinal direction is restricted when the lower frame 1 is connected to the vertical frame. 6, the movement of the rail member 3 is restricted by a cap 5 that closes the end of the rail member 3. Since the longitudinal end of the rail member 3 only abuts on the cap 5, if the restraining member 4 is removed, the rail member 3 is moved to the lower frame body 2.
Can be separated from FIG. 6 shows the use state of the lower frame 1. The water falling on the rail member 3 falls from the drain hole 34 to the prospective piece 21 of the lower frame main body 2, and falls on the prospective piece 24. Is the drainage hole found in the found piece 23 through the prospect piece 24 as it is
From 27 flows into the bathroom. When the lower frame 1 is used as a lower frame of an opening facing the outside like an entrance sliding door or a terrace door, it is discharged to the outside along the same route. According to the present invention, the rail member is sandwiched between the locating piece of the lower frame body and the rail member, and restrains the movement and lifting of the rail member in the expected direction by a restraining member straddling between the lower frame body and the rail member. In order to keep it connected to the lower frame body,
It is not necessary to connect at a plurality of locations in the same cross section as in the case of using a screw, so that the number of operations for connection is reduced, and workability and assembly efficiency are improved. Further, since the restraining member is disposed between the rail member and the locating piece of the lower frame main body, the rail member can be easily attached and detached even after the lower frame is put in a use state, and the rail member and the lower frame main body can be connected to each other. It is possible to cope with cleaning of the upper surface and replacement when the rail member is damaged. The rail member rests on the prospective piece of the lower frame main body, is supported by the lower frame main body, and is restrained from moving and floating in the prospective direction by the restraining member, thereby preventing deformation due to the load of the wheelchair. It is stable against detachment from the lower frame main body due to passage of a wheelchair, and does not come off from the lower frame main body.
