Description

[Detailed Description of the Invention] The present invention relates to a sliding door suitable for use in the entrance, exit, back door, etc. of a bathroom.

For example, in a conventional sliding door as shown in FIG. The opening width P is equal to the width W of the opening frame 4, which is equal to the sum of 1/2 of the dimension A of the stile (or door frame) 3 and the dimension B of the vertical frame 5.
When a sliding door is installed in a narrow space, it often causes inconvenience for people to enter and exit, and for goods to be brought in and out.

In view of the above-mentioned conventional problems, the present invention aims to provide a sliding door whose opening width can be adjusted.Auxiliary members are attached to the building opening frame or shoji in a foldable manner, and when the shoji is opened, the sliding door can be adjusted. It is characterized in that the opening width can be increased by folding the auxiliary member.

Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. In the first embodiment shown in FIGS. 2 and 3, numeral 10 is a building opening frame that is attached to the entrance and exit of the melting room, etc. Left and right vertical frames 10a, 10
b, an upper frame 10c, and a lower frame 10d, and a movable shoji 11 and a sliding shoji 12 that can be opened and closed left and right are attached to the opening frame 10.

The movable shoji 11 has left and right vertical frames 13a, 13.
b, an upper stile 13c, and a lower stile 13d are assembled into a rectangular shape, and a glass 14 is attached thereto, and a door wheel 15 and an engagement piece 16 are attached to the lower stile 13d.
The door roller 15 is placed on the flat rail surface 17 provided on the lower frame 10d of the opening frame 10, and the engaging piece 16 is engaged with a guide wall 18 formed downward on the lower frame 10d. The structure is such that the movable shoji 11 can be opened and closed smoothly while being prevented from coming off by the engagement of the shoji 11. And the movable shoji 1
A handle 19 is attached to the vertical stile 13a on the door edge side in 1 for opening/closing operations, and a frame-shaped aid is attached to the vertical stile 13b on the matching side to adjust the opening width when the movable shoji 11 is opened. The member 20 is foldably attached so that it can be folded back 180 degrees, and a locking member consisting of a leaf spring-shaped elastic locking piece 23 and its locking wall 24 is attached to the auxiliary member 20 and the vertical stile 13b. Means 22 are provided, and the auxiliary member 20 is held by this locking means 22 to prevent it from being folded up unnecessarily.

Note that as the locking means 22, it is also possible to use one that utilizes the attraction force of a magnet.

On the other hand, the fitted shoji 12 has left and right 25a, 2
5b, an upper stile 25c, and a lower stile 25d are assembled into a rectangular shape, a glass 26 is stretched over this, and this is fixedly attached to one side of the opening frame 10.

Therefore, as is clear from Figure 4, the above 2
The width D of the two shoji 11 and 12 is formed to be 1/2 of the width W of the opening frame 10 or smaller than that,
Moreover, the width E of the auxiliary member 20 is the same as that of the two shoji 11,
It is formed to be the sum of the distance C between the vertical frames 13b and 25a in 12 and the dimension A of the vertical frame 25a.

Note that 27 in the figure indicates a door stopper.

In the sliding door having the above configuration, the movable shoji 11
When the movable shoji 11 is closed, the auxiliary member 20 is extended so as to be in line with the shoji 11 and held in that state by the locking means 22, as shown by the solid line in FIG. When opening the
The auxiliary member 20 is folded as shown by the chain line, and the shoji 11 is opened in this state. As a result, the opening width becomes wider by the amount by which the auxiliary member 20 is folded.
That is, as shown in FIG. 4, if the dimension of the vertical stile 10a in the opening frame 10 is B, the opening width P is as follows: P=W/2+C/2-B, where C/ If 2=B, then P=W/
2, that is, the opening width can be made 1/2 of the width of the opening frame 10, and if C/2>B, then P>W/
2, that is, the opening width can be made larger than 1/2 of the width of the opening frame 10.

Further, on the upper surface of the lower frame 10d, no wall-shaped rails for the door roller 15 or other partition walls are formed in an upright state, and the entire lower frame 10d is formed in a substantially flat shape. Even if the device is touched with bare feet or bare hands, the user will not be injured or feel pain at the contact portion, and therefore, even a disabled person can easily and safely enter and exit through the opening.

In the above embodiment, a single sliding door made of one movable shoji was described, but it goes without saying that a sliding door having a plurality of movable shoji that can be opened and closed can have a similar configuration.

As described above, according to the present invention, since the auxiliary member is foldably attached to the shoji, the opening width of the sliding door can be increased by folding the auxiliary member when the shoji is opened. Moreover, the above auxiliary members
Since it can be folded back 180 degrees, it is very compact when folded, so the auxiliary member does not protrude to the side of the shoji and become an obstacle to entering and exiting or passing through, or may come into contact with the body and cause injury. Moreover, when the shoji is opened, the auxiliary member will not come into contact with equipment such as a melting tank or a toilet bowl, and will not interfere with the opening/closing operation. Furthermore, since a locking means for holding the auxiliary member in the extended position is provided, the auxiliary member may be folded automatically when it does not need to be folded, or may dangle when opening and closing the shoji. There is no such thing as giving support to someone.
