Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for preventing the removal of a shoji screen installed in a sash frame.

[Prior Art] Japanese Patent Application Laid-Open No. 58-44173, which discloses a technology for a shoji shoji slip-off prevention device, discloses a lower stile in which an outer rail projects upward from an inner rail and a long inner flange is formed on the outer rail. A sliding window is described in which the inner flange contacts the outer rail and prevents the outer shoji from coming off toward the outdoor side even when the outer shoji is erected and the outer shoji is lifted and pulled out to the outside. .

[Problems to be solved by the invention] However, in this prior art shoji slip-off prevention device, it is necessary to manufacture a special lower frame in which the outer rail protrudes longer than the inner rail. easily deforms under the full weight of the outer shoji,
There are problems such as not being able to withstand long-term use.

Therefore, this invention was developed in view of the above-mentioned problems of the prior art, and was designed to solve the problem by using the conventional lower frame to make the shoji room solid and secure without producing a special lower frame. The object of the present invention is to obtain an inexpensive device that can prevent removal to the outside.

[Means for Solving the Problems] As a means for achieving this, this invention includes an engaging body that is slidably attached to the rail and is swallowed by the space between the door wheels provided on the lower stile of the shoji, and The overlapping dimension between the engaging body and the indoor side wall of the lower stile facing it is larger than the lifting dimension of the shoji, and the overlapping dimension between the engaging body and the outdoor side wall of the lower stile facing this is smaller than the lifting dimension of the shoji. This is the setting.

[Example] An example in which the specific configuration of this invention is shown in the drawings will be described in detail below.

The drawing shows an example of a sliding shoji,
1 is a sash frame consisting of an upper frame 2, a lower frame 3, and left and right vertical frames 4, 4, and an upper outer rail 5 and an inner rail 6 are provided protruding from the upper frame 2 at intervals in the viewing direction,
A lower outer rail 7 and an inner rail 8 are protruded from the lower frame 3 facing this so as to correspond to the upper outer rail 5 and inner rail 6, respectively, and an outer shoji screen is provided between the upper and lower outer rails 5 and 7. 9. The inner shoji 10 is slidably built between the upper and lower inner rails 6 and 8, respectively. Matagato Shoji 9
The outdoor side wall 9c of the lower stile 9a is formed shorter than the lower ends of the indoor side wall 9b and both side walls of the lower stile 10a of the inner shoji 10, and furthermore, there are rails running on the outer rail 7 near both left and right ends of the lower stile 9a. The door wheels 11, 11 are attached in the same manner as before, and a space 12 for swallowing the engaging body is formed between the two door wheels 11, 11. Reference numeral 13 denotes an engaging body, which is made of a long and narrow corner member, and is cut into a T-shape from the center of the lower end to form a guide groove 14 along the longitudinal direction, which is fitted into the lower outer rail 7. The engaging body 13 is attached so as to be slidable left and right along the outer rail 7, and is disposed in the space 12 between the double-door rollers 11, 11 of the outer shoji 9 built on the outer rail 7. The overlapping dimension a between the engaging body 13 and the indoor wall 9b of the lower stile 9a facing it is determined by the rail swallowing notch 9e formed on the upper part of the vertical stile 9d of the outer shoji and the outer rail 5 fitting therein. The lifting dimension b of the outer shoji 9 is set larger than the lifting dimension b, and the overlapping dimension c of the engaging body 13 and the outdoor wall 9c is set smaller than the lifting dimension b of the outer shoji 9.

Note that the upper end of the engaging body 13 on the outdoor side is cut into an inclined shape 13a to facilitate removal of the outer shoji 9, and a notch 9e for receiving a rail provided in the vertical frame of the outer shoji 9 makes removal easier. It is widened inward to make it smooth.

With this structure, the outer shoji 9 built in the sash frame 1 can be opened and closed left and right by the door roller 11 running on the lower outer rail 7.
At this time, the engaging body 13 is also located in the space 12 of the lower stile 9a between the door rollers 11, and is pushed by the door roller housing 11a and slides from side to side on the outer rail 7 together, so the outer shoji 9 remains the same as before. Can be moved smoothly. When removing the outer shoji 9, remove the inner shoji 10 and then lift the outer shoji 9. The lower end of the outdoor side wall 9c of the lower stile 9a will be pulled up above the upper end of the engaging body 13, so the outer shoji 9 It can be easily removed by tilting the lower part towards the indoor side and pulling it out. However, when trying to take the outer shoji 9 to the outside, the overlapping dimension a of the engaging body 13 and the indoor wall 9b is larger than the lifting dimension b of the outer shoji 9, so the lower stile 9a of the outer shoji 9 The side wall 9b abuts against the engaging body 13 and cannot be taken out, and removal of the outer shoji 9 to the outside of the room is reliably prevented.

Note that this invention is not limited to the sliding shoji of the above embodiment, but can also be applied to, for example, single sliding doors.

[Effects of the invention] As described above in detail with respect to the embodiment, this invention has the engaging body slidably attached to the rail, so there is no risk of hindrance to the opening/closing operation of the shoji, and it can be done in the same way as the conventional one. The shoji can be run smoothly, and the shoji can be reliably prevented from being removed to the outside. Furthermore, by attaching the engaging body to the rail, it is possible to use the lower frame that has been commonly used in the past, and there is an effect that a robust device can be obtained at low cost without the need to manufacture a special lower frame. It is something.
