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) one of the fins protruding from the opposing surfaces of the two guide rails of the upper frame of the shoji is provided with two notches at a distance approximately equal to the width of the shoji, and the part that overlaps with the notches is cut out. Utility Model No. 53-122042 with a fixed stop. (2) Either a male thread or a female thread member is fixed to the upper frame, and the other member is screwed into this.

No. 158467. (4) A piece-shaped contact part is removably attached to a locking part provided on the upper frame.
No. 29763, (5) There is a device in which a retaining piece is pivotally attached to the upper frame so as to be freely rotatable downward, and the retaining piece is locked and held in a horizontal position.

Problems to be Solved by the Invention Although some of the conventional techniques have been listed above, these conventional techniques only partially attach the stopper to the upper frame (Utility Model Application No. 54-158467 (The number is attached to the vertical stile of the shoji, but it is the same in that it is partially the same).As shown in Figure 7, when a force is applied to lift the entire shoji 1 directly upward, the shoji Since the upper stile 2 of 1 hits the stopper 100 and is prevented from being lifted, the above-mentioned derailment, falling,
Accidents such as removal from the outside will not occur.

However, when only one side of the shoji 1 is lifted as shown in Fig. 8, 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. (5) Utility Model Application Publication No. 171248/1987 shows a long retaining piece, but the retaining piece is still provided in a part of the opening/closing movement range of the shoji, which causes the above-mentioned accident. It was hot.

Means for Solving the Problems In view of the above-described shortcomings of the conventional device, the present application forms a downwardly projecting shoji guide rail on the upper frame and forms two guide grooves separated by the shoji guide rail. In a slide 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 the two guide grooves has an area facing the top surface of the shoji in the closed position and an area opposite to the top surface of the shoji in the open position. A restraining material having a vertical height dimension that can limit the amount that the shoji can be lifted to be smaller than the amount of lifting required for removing the shoji is provided on each of the upper surface and the opposing area, and each of the restraining materials is placed on the side of the shoji in the direction of movement. Consisting of two rod-shaped contact frames with a length slightly shorter than half the width, one of these two contact frames is placed at the bottom of the guide groove, and the other is placed at the bottom of the other guide groove. Both of them are arranged so that they cooperate to extend substantially the entire length of the shoji in the moving direction of the shoji in the above-mentioned area, and the above-mentioned four contact frames are arranged so that at least two adjacent frames can be removed from that position. It is characterized by consisting of

Effect With the above configuration, in this application, the upper stile of the shoji corresponds to the restraining material during the entire process of opening and closing the shoji, so no matter what force is applied to the shoji, it will not fall off or fall. There is absolutely no possibility of removal from the outside, and when installing or removing the shoji, it is extremely easy to do so by removing at least two adjacent abutment frames from their installation positions.

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.
