DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper for a sliding door that slides horizontally in a window frame such as a sliding sash.

[0002]

2. Description of the Related Art In general, a sliding sash or the like has a structure in which a sliding door can be removed at a predetermined position in a window frame in advance in order to replace a sliding door of a sliding door or to perform a mounting adjustment. ing. However, it is extremely dangerous if the shoji is accidentally detached from the window frame at an open position other than the predetermined position. For this reason, a detachment stopper is used to prevent accidental detachment at a position where a part of the shoji is opened other than the closed state.

For example, as shown in FIG. 5A, an upper frame 80 of a sliding sash is provided between a plurality of guide rails 82 for guiding a shoji (not shown) between each other. A block 86 for adjusting the interval between the frame 80 and the horizontal piece 84 is inserted and fixed to the horizontal piece 84 by a screw 87. A sealant 88 is applied to the tip of a screw 87 that penetrates the horizontal piece 84.

As shown in FIG. 5 (B), a fixed member 101 mounted on the upper frame 90 is inserted between guide rails 92 which guide the upper part of each sash, and a disengagement screw is engaged with the fixed member 101. Shoji disengagement prevention device 1 comprising a stopper 106
No. 00 has also been proposed (see Japanese Utility Model Laid-Open No. 57-78361). This stopper device 100 inserts a flange 102 above a fixing member 101 between a pair of opposed horizontal grooves 98 formed between a horizontal flange 94 and a horizontal piece 96 above the rail 92, and The male screw portion 108 of the stopper 106 is screwed into the female screw portion 104 formed at the center of 101 to make the stopper 106 rotatable.

[0005]

In the block 86 shown in FIG. 5A, it is necessary to form a female screw hole for a screw 87 at a predetermined position of the upper frame 80 and apply a sealant 88. For this reason, there is a problem in that complicated work is required for positioning and fixing the block 86, and also a step of applying and drying the sealant 88 is required. Also,
5B, the fixing member 101 is inserted from one end of the single upper frame 90 in advance and slid to the predetermined position between the horizontal grooves 98, or assembled into a rectangular window frame. The notch of the horizontal flange 94 in the upper frame 90 thus formed requires processing and labor such that the flange 102 of the fixing member 101 is inserted from the notch and then slid to a predetermined position. Further, the fixing member 10
1 to fix the position of the horizontal flange 94 of the upper frame 90.
Since the stopper 106 is screwed together after caulking, the assembly man-hour is increased, which is complicated.

In addition, the block 86 shown in FIG.
(B) can be attached only in the intermediate process of sash assembly, for example, to accommodate the shoji size of each region and to adjust the installation after carrying to the construction site The position of the stopping device 100 or the like cannot be finely adjusted. Furthermore, there has been a problem that, for example, if the battery has been deformed or damaged carelessly after being used for many years, it cannot be replaced. The present invention solves the above-mentioned problems in the prior art, and can be easily attached even after construction, as well as during assembly of the sash, and is hard to come off.
It is an object of the present invention to provide a shoji sliding stopper that can be replaced as necessary.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, each side surface of the guide rail facing the upper frame is prevented from coming off by means of a claw which locks on one side and a screw which abuts on the other side. It was made with the idea of self-holding. That is, the stopper of the sliding door of the present invention has a rectangular main body inserted between a pair of guide rails in an upper frame that guides the sliding sash horizontally, and one side of the guide rail from one side of the main body. A locking claw protruding toward the main body, an inclined surface formed at a position substantially symmetrical to the locking claw on the other side surface of the main body, and screwed into the vicinity of the inclined surface after entering from the bottom side of the main body. And a tip having a tip protruding on the inclined surface, and a pointed tip formed at the tip of the screw and abutting against the other of the guide rails.

In this stopper, the main body is inserted between the guide rails of the upper frame, the locking claws are brought into contact with the side surface of one of the guide rails, and a wrench is inserted into, for example, a hexagonal hole at the base end of the screw. Then, the screw is moved obliquely upward to force the pointed end of the screw into contact with the side surface of the other guide rail, so that the locking claw also contacts the side surface of one guide rail. As a result, the main body can be securely and firmly locked and fixed between the guide rails by the locking claws and the pointed portions of the screws on both sides thereof. Therefore,
It is easily mounted and fixed at a desired position during assembly of the sash and the like, as well as after construction, and is not easily detached, and can be easily removed as necessary.

In addition, a plurality of the locking claws are protruded, and
The same number of the screws may be screwed together so that their tips come out on the inclined surface substantially opposite to the locking claw, or the screws may be mounted on the opposite inclined surface between the plurality of locking claws. Also includes a shoji slip stopper that is screwed so that its tip comes out. According to this, the locking claw and the screw are located at substantially symmetrical positions on both side surfaces of the main body.
The main body can be firmly fixed. Further, when the screw is located on the opposite side between the plurality of locking claws, for example, the main body can be fixed to only two locking claws with only one screw, and the operation can be further simplified.

[0010] Further, the main body includes a rectangular block,
A locking plate fixed to the upper surface of the locking plate, the locking claw protruding from one side surface of the locking plate, and the inclined surface being formed on the other side surface of the locking plate. It also includes a stopper for a sash that penetrates a female screw hole screwed into the screw on the inclined surface. According to this, the block is made of hard resin such as polyimide, and the locking plate is punched from a stainless steel plate or the like,
By bending and forming by female screw processing and assembling them, it is possible to easily and accurately manufacture the stopper. If a recess for accommodating the base end of the screw is formed below the inclined surface of the locking plate in the block, most of the screw body can be accommodated in the recess, and a relatively short screw can be accommodated. Can be used. Thereby, the whole can be downsized.

[0011] In another aspect of the present invention, there is provided a sliding stopper for a sliding door which is inserted between a pair of guide rails in an upper frame for guiding a sliding sliding door. A locking claw protruding toward one of the guide rails, an inclined surface formed at a position substantially symmetrical to the locking claw on the other side surface of the main body, A screw which is screwed in the vicinity of the inclined surface and whose tip comes out on the inclined surface, a moving body which is non-rotatably supported by the tip of the screw, and which comes into contact with and separates from the inclined surface; And a locking projection protruding from the side surface toward the other side of the guide rail. According to this, with a small number of screw operations, the moving body is moved obliquely upward and the locking protrusion is brought into contact with the side surface of the other guide rail, so that the locking claw on the opposite side is moved to the one guide rail. The main body can be securely attached and fixed by being brought into contact with the side surface.

[0012] Further, it is also possible to provide a shoji sliding stopper in which one or more liners are fixed to the bottom surface of each of the above main bodies near one end in the longitudinal direction along the guide rail of the upper frame. Thereby, the gap between the upper frame and the shoji can be further appropriately adjusted at a desired position. In this case,
It is desirable that the locking claw, the screw, or the locking plate having these are provided or fixed at an intermediate position in the longitudinal direction of the main body or the block. However, the locking claw, the screw, or the locking plate having the locking claw, the screw, or the like is provided near one end in the longitudinal direction of the main body or the block, and the stopper that fixes the liner to the bottom surface near the other end is also included.
