Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door device for a sliding door toilet, and more particularly to a door device that automatically and temporarily holds and stops a sliding door at the end of its moving stroke.
[0002]
[Prior art]
Conventionally, a toilet booth of a sliding door is urged by urging means so that the door is always in an open state or a closed state.
[0003]
[Problems to be solved by the invention]
When the above door is biased to the normally open side, when the user enters the toilet booth and tries to lock the door with the door closed, if the user releases the door, the door moves in the opening direction and cannot be locked. In particular, there is a problem that it is very difficult for a wheelchair user to perform a locking operation while sitting on the wheelchair.
Also, if the door is biased to the normally closed side, when the door is opened and you try to enter or exit the toilet booth, if you take your hand off the door, the door will move in the closing direction. There is a problem that the wheelchair must be pushed forward with one hand while holding with one hand.
[0004]
In order to solve such problems, an object of the present invention is to provide a door device provided with a function of temporarily and automatically stopping a door in a sliding door toilet at the end of its moving stroke. It is said.
[0005]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) By arranging a rail from the opening to the door storage place at the upper part of the side wall, hanging the door on a suspension vehicle movable within the rail, and moving the door along the rail, In the sliding door toilet door apparatus that opens and closes the opening, an urging means for urging the door toward one end of the rail, and the door at the other end of the rail in, setting the holding means for holding with a slightly larger holding force than the biasing force of the door by the biasing means only, said holding means, a plate spring made of two tongues gently bent downward convex It is assumed that the downward convex portions of both tongue pieces fall between two pairs of wheels spaced apart in the longitudinal direction of the rail in the suspension vehicle and are fixed to the mounting brackets at positions where they can be engaged on the respective wheels .
[0006]
(2) In the above item (1), the biasing means is a door normally open type that biases the door to the open side, and the holding means holds the door at the opening closed position.
[0007]
(3) In the above item (2), the side wall is erected on the left and right sides, and the upper part of one side wall is convexly curved toward the side wall, and the upper part of the front opening is convex toward the front side. Curved continuous arc-shaped rails are arranged at the upper part of the left and right side walls, and the arc-shaped door is opened from one side wall side, and the front opening is closed from the inside. Between the locked state and the lockable state, the rail is movably supported on the rail, and the handle is locked inside the one side wall end of the arcuate door, and locked inside the one side wall side. Attach means.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of the sliding door toilet of the present invention.
FIG. 1 shows a door open state, and FIG. 2 shows a door closed state.
[0009]
As shown in FIGS. 1 to 3, the toilet booth (1) is defined by left and right side walls (2) and (3), and an opening (4) is provided in front of the toilet booth (1).
On one side wall of the opening (4) in front of the toilet booth (1), that is, on the front side of the left side wall (2), there is a front wall (5) protruding from the opening (4). A similar short front wall (6) is also attached to the front of the right side wall (3).
[0010]
As shown in FIG. 3, above the opening (4), an arc-shaped rail (7) having a central protrusion as the front has a short column (not shown) and the side wall (2) (3) or It is supported by the front walls (5) and (6) and extends from the opening (4) to the door storage location along the side wall (2).
[0011]
On the arc-shaped rail (7), an arc-shaped door (8) having the same curvature is movably supported by a suspension wheel (9) attached to the upper end near both ends thereof.
[0012]
Inside the rail (7), for example, a known biasing means (10) such as a constant torque spring called a trade name Conston spring is disposed, and the arcuate door (8) is a biasing means. By (10), it is always urged to the opening opening position shown in FIG.
[0013]
A holding means (11) is attached inside the end of the rail (7) on the other side wall (3) side. Holding means (11), as shown in FIG. 4, the two tongues gently bent downward convex leaf spring consisting of (12a) (12), the downward convex portion of Ryozetsu piece (12a) longitudinally of the two pairs of spaced wheels of the rail (7) in the suspension sheave (9) (9a) (9a), it can be engaged on the (9a) depressed between (9a), each of the wheels (9a) At the position, it is fixed to the mounting bracket (13), and the mounting bracket (13) is fixed inside the rail (7).
[0014]
When the door (8) reaches the opening closed position (FIGS. 2 and 3), the holding means (11) engages with the suspension wheel (9) on the side wall (3) side, The door (8) is stopped by temporarily and temporarily locking. At this time, the door (8) is urged in the opening opening direction by the urging means (10), but the force of the holding means (11) overcomes this urging force to hold the door (8). ing.
[0015]
1 and 2, reference numeral (14) is a handle attached to the inner side of one side wall (2) of the door (8), and reference numeral (15) is attached to the inner side of the front wall (5). The locking means engages with the edge of the door (8) to lock the door (8).
[0016]
The door device of the present invention is configured as described above. In use, as shown in FIG. 1, the door device enters the toilet booth (1) from the normally open opening (4) and faces forward. The handle (14) of the door (8) is pushed by hand to move the door (8) against the force of the urging means (10) until the opening is closed as shown in FIG.
Then, the holding means (11) described above with reference to FIGS. 3 and 4 catches the suspension vehicle (9) and holds the door (8) at that position to bring it to a stopped state. In this state, even if the hand is released from the door (8), the door (8) does not move, so the locking means (15) is hung with the released hand.
It goes without saying that when going out of the door booth (1), the procedure is reversed.
The biasing means (10) is not limited to the above-described Conston spring, and may be one using a weight, for example, and the holding means (11) is not limited to a leaf spring type, for example, a magnet. It may be used.
[0017]
If the door (8) is of a normally closed type, the holding means (11) is disposed at a position for holding the opposite side of the door (8). In this case, when the door (8) is moved from the outside to the open position shown in FIG. 1, the holding means (11) is actuated, and the door (8) is held at that position and is placed in the toilet booth (1). If the handle (14) is slightly pushed after entering, the door (8) is automatically moved to the opening closed position shown in FIG. 2 by the urging means (10). At this time, the locking means (15) may be hung.
[0018]
【The invention's effect】
According to the first aspect of the present invention, the door can be temporarily held at the end of the moving process, the door and the locking means can be operated with one hand, and even a wheelchair user cannot use the toilet alone. It can be done easily.
In addition, it is possible to obtain a temporary holding means that is reliable in operation with a simple structure.
[0019]
According to the second aspect of the present invention, when the user enters the toilet booth and closes the door, the door does not open even if the user releases the hand, so that the door can be locked as it is, and the door can be operated with one hand. .
[0020]
According to the third aspect of the invention, since the door that moves in the left-right direction at the front opening is housed in the side portion of the indoor space, the toilet booth is made compact, and the handle of the door is connected to the door end on the side portion side. By providing the locking means on the side portion and the side portion, the convenience during operation is improved.
