Description

[Detailed description of the invention] Industrial application field The present application relates to a sash shoji removal prevention device that can be applied to all types of sliding sashes, such as single-sliding, double-sliding, and bypass sliding sashes. The aim is to prevent this from happening.

Prior Art As is well known, when satsushi shoji is opened and closed, shock or unexpected external force may cause the door roller to come off its wheels or come off the bottom frame and fall. Since there is a risk of serious accidents occurring in high-rise buildings, every possible measure must be taken to prevent them. Furthermore, even when the locking device is in operation, the sash shoji may be stolen by being removed by lifting the shoji from the outside due to various defects such as wear of the locking device.

In order to prevent the above-mentioned satsushi shoji accidents,
A large number of locking devices have been proposed in the past, as described below. For example, (1) two notches are provided on the fins protruding from the opposing surfaces of the two guide rails of the shoji upper frame at an interval approximately equal to the width of the shoji, and a retainer is fixed to the part that overlaps with these notches. Tenaru Mikai Showa 53-
The invention described in Publication No. 122042. (2) One of the male threaded or female threaded members is fixed to the upper frame, and the other member is screwed into this.
The invention described in Publication No. 157538. (3) Japanese Utility Model Application Publication No. 158467/1987, which is attached to the vertical frame of a shoji screen, operates with a stopper in conjunction with the operation of a locking device, and is released by a release member in the closed position. The invention described. (4) Many of the ideas described in Japanese Utility Model Application Publication No. 58-29763, in which a piece-shaped contact part is removably attached to a locking part provided on the upper frame, have been put into practical use. .

Problems to be Solved by the Invention Although some of the conventional techniques are listed above, these conventional techniques only partially attach piece-shaped retainers to the upper frame. 54−
No. 158467 is attached to the vertical stile of the shoji,
As shown in Fig. 4, when a force is applied to lift the entire shoji 1 directly upward, the upper stile 2 of the shoji 1 hits the stopper 100 and the lifting is stopped. Therefore, in this case, accidents such as derailment, falling, and removal from the outside do not occur.

However, when only one side of the shoji 1 is lifted as shown in Fig. 5, the above-mentioned accident occurs because the shoji 1 is lifted in an inclined state centered on the contact point between the stopper 100 and the upper stile 2. It is something.

Means for Solving the Problems In view of the above-described shortcomings of the conventional device, the present application forms a shoji guide rail that projects downward on the upper frame, and also forms two guide grooves separated by the shoji guide rail. In a sliding sash in which the upper part of the shoji is guided by the shoji guide rail so that the upper part of the shoji can be opened and closed, the bottom of one of the guide grooves has an area facing the top surface of the shoji in the closed position and an area facing the top surface of the shoji in the open position. Approximately half the area on the vertical frame side and the other approximately half area in each of the areas facing the shoji are provided with vertical heights that can limit the amount by which the shoji can be lifted to be smaller than the amount by which the shoji can be lifted to a value smaller than the amount required to remove the shoji. Bar-shaped abutting frames with a length slightly shorter than half the width of the shoji in the direction of movement of the shoji are arranged in a straight line, and these abutting frames on the vertical frame side are fixed to the bottom of the guide groove. The abutment frame on the other side is attached to the bottom of the guide groove so that it can slide in the longitudinal direction, and the abutment frame on the vertical frame side and the abutment frame on the other side can be inserted into either one. It is characterized by having a hollow part over the entire length.

Effect With the above configuration, in the present application, the upper stile of the shoji corresponds to the contact frame during the entire opening and closing process of the shoji, so no matter what force is applied to the shoji, it will not fall off its wheels. There is no possibility of removal from the outside. Moreover, when the shoji is installed or removed, it can be done very easily by sliding the two abutment frames on the middle side of the shoji opening/closing area from their respective installation positions to the vertical frame side.

Embodiments Next, the present application will be described in detail with reference to drawings showing embodiments. As mentioned above, the device of the present application is applicable to all types of sliding sashes, such as single-sliding and double-sliding. unit,
That is, only the case where it is applied to a single-stripe sash will be explained.
Needless to say, when the device of the present application is applied to double sliding or other purposes, the device of the present invention shall be added as detailed below depending on the number of satsushi shoji.
