Description

  The present invention relates to a sliding door type joinery structure installed on a partition wall inside a building.

  Conventionally, when installing furniture for entrance / exit on the partition wall where a wheelchair user lives or uses, the amount of movement when opening and closing is less than that of the hinged door type, and it is easy to use even in narrow corridors etc. It is considered preferable to employ a sliding door type fitting.

  However, sliding doors are relatively small like a house because it is necessary to secure the allowance for retracting the door to secure the opening width, and it is necessary to secure a remnant part for providing a handle for closing the open door. In the case of a building that needs to be divided and used with a partition wall or the like according to the purpose despite its size, a desired opening width cannot be ensured, which may hinder access.

  Patent Document 1 proposes an entrance / exit structure that can solve such a problem. The entrance / exit structure disclosed in Patent Document 1 is a structure in which a main door and a child door having different width dimensions are provided to be different from each other, and can usually be used as a normal one-way door, and the main door and the child door are removed. Thus, a sufficient opening width of the entrance / exit can be secured.

JP 2001-207662 A

  However, the entrance / exit structure of Patent Document 1 cannot widen the opening width while the door is still fitted in the frame, and each time the opening width is widened, both the main door and the child door are framed. There is a problem that it takes time and effort to remove it, and there is also a problem that this operation cannot be performed by a wheelchair user himself and cannot be used without the presence of a caregiver or the like. In addition, as in the usage mode assumed in Patent Document 1, when the door is left off for a wheelchair user and is shielded by simple means such as a curtain, there is a problem that sufficient privacy cannot be secured. there were.

  The present invention solves the above-described problems of the prior art, and allows the wheelchair user to easily widen the opening width while riding on the wheelchair as needed, and also has privacy equivalent to that of a normal sliding door. It is an object of the present invention to provide a sliding door structure that can be secured and does not interfere with the use of healthy people.

  The sliding door structure according to the present invention includes a single-drawing type door and a frame, and the door is disposed on the first door disposed on the retracting side of the frame and on the opening side of the frame. The first door has a width that is greater than or equal to the pull-in allowance of the frame body, and is fitted into the guide portions of the upper and lower frames constituting the frame body. The second door is connected with a hinge in a state where the first door and the lateral hand are opposed to each other, and the first door is rotated by about 180 ° around the hinge. It is characterized by being configured to be able to overlap.

  According to the sliding door structure of the present invention, the door is divided into the first door and the second door, and the portion protruding to the opening side of the frame can be folded with the hinge as an axis. Even when it is not possible to secure sufficient, the opening width of the frame can be increased, and the wheelchair user can easily go in and out.

  Further, when the opening width is widened, a particularly large-scale work is not required, and the independence of a wheelchair user who does not have a hand function obstacle can be promoted.

  In addition, it can be used in the same way as a general sliding door type fitting, and it is not inferior to a general sliding door type fitting in terms of ensuring privacy. Can be used comfortably.

  Hereinafter, the best mode of the sliding door structure according to the present invention will be described. The present invention realizes a sliding door structure that is easy to use for both wheelchair users and healthy persons by making minor changes to the doors that constitute a conventional general sliding door structure.

  The frame constituting the sliding door structure of the present invention is a frame for a general single sliding door comprising an upper frame, a lower frame, a vertical (vertical left and right frame), and a central vertical (intermediate vertical frame). The same configuration may be used. However, the neutral position needs to be set so as to obtain a desired opening width.

  Like the frame for a general sliding door, the upper and lower frames are equipped with grooves and rails that serve as guides for sliding the door. It is preferable to configure so as not to occur. When installing a door at the boundary between a corridor and a room such as a toilet, the door will slide along the surface of the room even if it is configured to slide along the surface of the partition wall. It may be configured.

  The door which comprises the sliding door structure of this invention is comprised by the combination of the 1st door arrange | positioned at the drawing-in part side of a frame, and the 2nd door arrange | positioned at the opening part side of this frame.

  The first door is a general one-way pull type door whose upper end and lower end are fitted into a guide made of upper and lower frame grooves, rails, and the like and slide along the guide.

  The upper end portion is formed with a notch corresponding to the width of the groove of the upper frame, or a protrusion is provided. The lower end may be simply fitted into the groove in the lower frame corresponding to the thickness of the door, and the lower end surface may slide on the bottom surface of the groove, or the door may be moved on the rail of the lower frame by attaching the door But you can. However, in order to make it barrier-free, it is less affected by the step of the groove to install a door wheel with a V-shaped cross section on the outer periphery and run it on a V-shaped narrow groove (V rail). preferable.

  The width of the first door may be set to be equal to or larger than the allowance for the frame body, but in order to make the most effective use of the opening width of the frame body, When the door is fully retracted, it is preferable that the side wall of the door and the neutral lip are substantially aligned.

  The second door is connected to the first door by a hinge and interlocks with the movement of the first door. In a straight line, the hands are facing each other and the first door is flush with the first door. In the folded state as the axis of movement, the surfaces on the same side as the first door are configured to face each other and overlap each other. Therefore, a notch part and a door wheel are not provided, and the upper and lower frame guides are configured so as to freely rotate by cutting an edge. In normal use, the second door does not fold, but opens and closes in the same way as a normal sliding door in a straight line with the first door. When the wheelchair user enters and leaves, the second door is folded to widen the opening width. To use.

  The width of the second door is not particularly limited, but the second door does not interfere with the indoor equipment when the hinge is pivoted, and the wheelchair user evacuates the body and wheelchair. It is necessary to set so that it does not need to be allowed.

  The hinge used for the connection between the first door and the second door is not particularly limited, but a hinge that is excellent in design without causing a large gap in the connecting portion is preferable.

  In the case where the gap between the connecting portions of the first door and the second door impairs privacy, it is preferable to provide an unevenness on the lateral surface so that the unevenness is engaged as a countermeasure.

  Moreover, it is preferable to provide a mechanism for preventing the second door from moving around the hinge in the folded state. However, the folded state of the second door is temporary and does not apply a large force, so a magnet catch, tape fastener (for example, Velcro (registered trademark)), sucker, etc. are simple and relatively weak. It is sufficient to restrict the movement with restraining force.

  Similarly, it is preferable to provide a mechanism for preventing the door from moving in a straight line that is not folded. In this case, since the first door is moved by grasping the puller of the second door, a relatively large force acts on the prevention mechanism, and the state is always in a straight line except when the wheelchair user goes in and out. Therefore, as the prevention mechanism, a mechanism capable of stably maintaining a straight line is preferable. For example, [1] A hook or a sickle lock is attached to the side to connect and release, and [2] A magnet having a relatively large magnetic force is attached to the side.

  The sliding door structure of the present invention is not limited to the door / door fitting structure, but can be applied to a door / door fitting structure.

  Next, an embodiment of the sliding door structure of the present invention will be described with reference to the drawings. In this embodiment, the sliding door structure according to the present invention is applied to an entrance for entering and exiting a toilet from a corridor of a house. 1 is a partial plan view of a house using a sliding door structure, FIG. 2 is a perspective view of the sliding door structure, FIG. 3 is a transverse sectional view of the sliding door structure, FIG. 4 is a longitudinal sectional view of the sliding door structure, and FIG. FIG. 6 is a perspective view of the hinge hinge. FIG. 7 shows a partially enlarged view of FIG.

  The sliding door structure 1 includes a frame body 10 and a door 20, and the frame body 10 is fixed to a partition wall 4 that partitions the hallway 2 and the toilet 3.

  The frame body 10 is composed of an upper frame 11, a lower frame 12, a stand 13, 14, and a center stand 15, and the door 20 is configured to slide on the toilet 3 side. On the lower surface of the upper frame 11, a groove 11a is formed in the longitudinal direction as an upper guide when the door 20 is slid. The lower frame 12 is embedded in the floor 5 so that the upper surface is substantially the same as the finished surface of the floor 5, and a metal V-rail as a lower guide of the door 20 is formed in a groove 12a formed in the longitudinal direction of the upper surface. 12b is accommodated. The uprights 13 and 14 have a width corresponding to the thickness of the partition wall 4 a of the general part of the partition wall 4, and the neutral stand 15 has a thickness of the partition wall 4 b of the lead-in part 16 of the partition wall 4. Have a corresponding width. The dimension from the end face of the stand 13 to the end face of the middle stand 15 is the width Wa of the opening 17 of the frame, and is set to a dimension that allows a wheelchair user to go in and out while riding on the wheelchair. Further, the dimension from the end face of the vertical 14 to the end face of the neutral 15 is the width (retraction allowance) Wb of the retracting portion 16.

  The door 20 includes a first door 21 disposed on the retracting portion 16 side of the frame body 10 and a second door 22 disposed on the opening portion 17 side of the frame body 10.

  The width W1 of the first door 21 is designed to be equal to the retracting allowance Wb of the retracting portion 16. A protruding piece 21a corresponding to the groove 11a formed in the upper frame 11 is provided on the upper end surface of the first door 21, and a shape corresponding to the V rail 12b accommodated in the groove 12a of the lower frame 12 is provided on the lower end surface. There are two door wheels 21b having the following cars.

  The second door 22 has a width W2 and has the same thickness and apparent height as the first door 21 (the height other than the portion fitted in the upper and lower frames), and the same finish. It is given and connected by a hinge 23. The hinge 23 is embedded in the side doors 21a and 22a of the respective doors, and the second door 22 is folded from the state of being aligned with the first door 21 and overlapped with the first door 21. It is pivotally connected. A large pull handle 25 is provided on the surface of the second door 22 on the corridor 2 side.

  The first door 21 and the second door 22 are normally used in a straight line state. Incidentally, in order to prevent the second door 22 from moving freely and maintain the straight state of the door 20, the hinge 23 has a built-in hook mechanism as shown in FIG. The scissors mechanism rotates the operation knob 24b to rotate the pinion gear at the tip end of the shaft 24d connected to the operation knob 24b, and projects the scissor bar 24a formed with a rack gear meshing with the pinion gear to be fitted into the hole 24c. The straight line state between the first door 21 and the second door 22 can be maintained. When the door 20 is pulled in this state, the second door 22 just protrudes from the end face of the neutral stand 15, and the effective width of the opening 17 is (Wa-W2).

  If it is desired to increase the effective width of the opening 17 from this state, the second door 22 can be rotated by turning the operation knob 24b with the door 20 retracted and pulling out the bar 24a from the hole 24c. Then, the second door 22 is folded and overlapped with the first door 21 (or the second door 22 may be folded and overlapped with the first door 21 and then retracted). By maintaining the folded state of the second door 22 in this manner and pulling in the door 20, the effective width of the opening 17 is widened by W2 to become Wa and easy to enter in a wheelchair-mounted state. become.

  After entering the toilet 3, the second door 22 is extended to be in a straight line with the first door 21, and then the door 20 is closed. When leaving the toilet 3, the door 20 is opened in the same manner as when entering. By doing so, it is possible to easily leave while riding on a wheelchair as in the case of entering.

  In addition, the magnet catch 26 is incorporated in the position which the 1st door 21 and the 2nd door 22 oppose in the folded state, and the floating in the state which the 2nd door 22 was folded is prevented. is doing. Since the movement of the first door 21 in the thickness direction is limited by the groove 11a and the V rail 12b, which are guides, the operation of extending the folded second door back to a straight line state is the second door 22 This can be easily performed by gripping only the first door 21 and pulling it away.
