Description

[Detailed explanation of the invention] This invention relates to a mechanism for preventing the sliding shoji from falling off.
The present invention proposes a mechanism in which the locking mechanism automatically operates and becomes locked by closing the upper shoji at the end of construction without using any tools.

In the conventional detachment prevention mechanism, a nylon block or the like is attached to the upper stile of the outer shoji, and this nylon block is fixed with a screw through a long hole.By loosening the screw and moving the nylon block downward, there is a gap between the nylon block and the upper sash. The gap is formed so that the shoji can be pushed up toward the upper frame, and the shoji can be removed from the window frame.

Therefore, removing the shoji from the window frame requires a tool to loosen the screws, which is troublesome.

Also, when the shoji is installed in the window frame, the nylon block must be returned to the raised position and the screws must be tightened.

``If you forget this step, the shoji may come off somehow, which is especially dangerous in high-rise buildings.

The purpose of this invention is that it is possible to change the state in which the lock is applied and the lock is released without using any tools, and even when the lock is released, the shoji can be temporarily closed. To provide a locking mechanism that can automatically return to a locked state.

An embodiment of this invention will be described below in detail with reference to the drawings.

In the figure, 1 indicates the upper azusa, and 2 indicates the outer shoji.

In this invention, a housing 3 for housing a retaining mechanism is attached to either one of the door end surfaces of the outer shoji 2.

In this example, as shown in FIG. 2, the housing 3 is attached to the door edge surface of the door frame 4 of the outer shoji 2.

The housing 3 is formed into a flat box shape, and is attached to the upper end of the door edge surface of the door frame 4 with screws 5 so that its flat surface is parallel to the door edge surface.

A movable element 6 having a shape as shown in FIG. 3 is housed inside the housing 3.

The movable element 6 is housed in the housing 3 so as to be movable in a direction perpendicular to the moving direction of the shoji 2, and is supported by a spring 7 so as to be always biased in one of the moving directions.

This example shows a case where the movable element 6 is biased toward the indoor side by the spring 7.

A cutout 3a is formed at the upper end of the housing 3 on the indoor side, and a part of the movable element 6 protrudes from the cutout 3a.

In the cutout 3a, the upper frame 1 faces, for example, the force guide 8 (when the mover 6 protrudes from the notch 3a, a slight gap g is formed between the mover 6 and the lower end of the guide 8).
Therefore, when the mover 6 protrudes from the notch 3f, the outer shoji 2 can only move upward by the amount of the gap g, and is prevented from coming off.

On the other hand, an operating body 9 is supported through the housing 3 in a direction parallel to the moving direction of the shoji 2.

That is, as shown in FIG. 4, a hole 10 penetrating in the moving direction of the shoji 2 is formed in the housing 3 on the side opposite to the mounting position of the spring 7.

Holes are also formed in the door end surface of the shoji 2 opposite to the holes 10 formed in the housing 3, and the operating body 9 is inserted through these holes 10.

The operating body 9 is a mover 6. The biasing force of the spring 7 is received through this projection 6a.

A recess 11 with steep notches at both ends is formed on the surface of the operating body 9 facing the movable element 6, and the protrusion 6a of the movable element 6 is inserted into the recess 11.

In other words, when the protrusion 6a is inserted into the recess 11, the movable element 6 faces the guide 8 of the upper frame 1 and is prevented from coming off.

This state is shown in FIG.

To release the locked state, it is sufficient to push the movable element 6 into the housing 3, and in this state, push the operating body 9 into the shoji 2.

By pushing the operating body 9 toward the shoji 2, the recess 11 of the movable element 6 moves from the position of the protrusion 6a to another position, so the movable element 6 is maintained in a state housed inside the housing 3. .

Therefore, the movable element 6 is not present in the notch 3a of the housing 3, and a large space is formed at the lower end of the guide 8.

In this state, the shoji 2 can be pushed up significantly and removed from the window frame.

□ Here, the dimensions of the operating body 9 are selected so that the operating body 9 will be in a state of protruding to the back side of the stile 4 of the shoji 2 when the lock is released.

In other words, when the locking state is released, the rear end of the operating body 9 protrudes to the position shown by the dotted line in FIG. 2.

In this state, when the shoji 2 is placed on the window frame and the shoji is closed, the stile 12 of the inner shoji collides with the rear end of the operating body 9 and moves in the direction that causes the operating body 9 to protrude. let

By this operation, the position of the notch 11 of the operating body 9 is adjusted to the position of the movable element 6.
The protrusion 6a of the movable member 6 engages with the recess 11.

Due to this engagement, the movable element 6 moves toward the indoor side, and the movable element 6 protrudes from the notch 3a of the housing 39, resulting in the state shown in FIG. 1, in which it is prevented from coming off.

,,1. ,'・As explained above, according to this invention, the locking state can be released without using any tools.

However, by closing the shoji after installation, it can be automatically set to the non-removable state, so even if you forget to set the shoji to the non-removable state, you can always set the shoji to the non-removable state. can.

Therefore, it is safe because it will not be left in a state where it is not secured.

Particularly during construction, the shoji is always closed and the door is checked to see if it can be locked, so at that point it will definitely become stuck.

In addition, since the operating body 9Iζ-shaped recess 11 has a sharp notch at both ends, the movable member 6 can be
1, the movable element 6 will not escape from the recess 11 even if a large force is applied to the operating body 9.

Therefore, the locking state will not be released inadvertently during practical use, and a highly reliable locking mechanism can be provided.
