Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a locking device for a rotating window that locks when the window is not opened.

[Conventional technology]

Conventionally, this type of rotating window and its locking device were the first
-Explained with reference to FIG. Top, bottom, left and right window frames 1A
A shoji frame framed by upper, lower, left and right shoji frames 2A to 2D within ~1D is rotatable by horizontal and horizontal rotation axes 3A and 3B. In the illustrated example, the rotation is clockwise in FIG.

Plate-shaped driven members 4A to 4D are engaged in the grooves of the shoji frames 2A to 2D. These driven members 4
A to 4D are connected at the corners of the shoji by a connecting member 5 made of a chain or a flexible thin plate. 6 is a sliding member at the corner portion. The lower driven member 4B is connected to an operating mechanism (not shown in detail) that is moved by an operating handle 7 located on the indoor side. Now, when the operation handle 7 is rotated, each driven member 4A to 4A is rotated through the operation mechanism.
4D rotates clockwise or counterclockwise in FIG.

On the other hand, at appropriate locations on the window frames 1A to 1D, for example, two locations per each window frame 1A to 1D, as shown in FIG.
Letter-shaped locking receiving portions 8A and 8B are formed. These locking receivers 8A, 8B are connected to the horizontal horizontal rotation shafts 3A, 3.
Above the line connecting B, the protruding piece 8a is deviated toward the indoor side, and below the line, the protruding piece 8b is deviated toward the outdoor side and fixed to the corresponding window frame with screws 9. In addition, locking pins 10A and 10B are provided at positions corresponding to the locking receivers 8A and 8B of each driven member 4A to 4D.
~It is integrated with 4D and protrudes toward the window frame side. Now, close the shoji and operate the operation handle 7.
Move the driven members 4A to 4D, and move the locking pins 10A,
When 10B is moved toward the shoji frame, the locking pin 1
0A, 10B move from the non-corresponding position to the corresponding position of the locking receivers 8A, 8B, and their tips are locked by the protruding pieces 8a, 8b of the locking receivers 8A, 8B. When opening the shoji, press the operating handle 7.
This is done after rotating in the opposite direction and removing the locking pins 10A, 10B from the locking receivers 8A, 8B.

Note that the shoji is equipped with inner and outer glasses 11 and 12 and a blind 13 between them.

[Problem that the invention attempts to solve]

By the way, in order to accommodate the shoji and the window frame, there are cases where the upper locking pin 10A has to be made longer, as shown in FIG. 1, for example. In this case, when the locking pin 10A is locked in the locking receiver 8A, when external wind pressure acts as shown by the arrow, the shoji rotates clockwise in FIG. 1 about the horizontal rotation axes 3A and 3B. As a result, the load is transmitted to the locking pin 10A, causing the locking pin 10A to bend and deform. As a result, attempts to release or relock the lock may not be successful. In addition, if the lock does not work, the shoji will not come into close contact with the window frame, and there is a risk of rainwater getting in.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a locking device that solves the above-mentioned conventional problems, prevents deformation of the locking pin, and allows the locking pin to move smoothly along with the driven member. .

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a guide reinforcing block that is located closer to the window frame than the driven member and is integral with the locking pin to prevent the locking pin from being bent. The block employs means for engaging the shoji frame so as to be movable in its longitudinal direction.

That is, according to the example in FIG. 1, the locking pin 10A integrated with the driven member 4A passes through the guide reinforcing block 20 and becomes integrated, and the guide reinforcing block 20 is integrated with the upper shoji frame 2A. It has a structure in which it is engaged so as to be movable in its longitudinal direction.

[Effect]

The locking pin 10A is integrated with a guide reinforcing block 20 fitted into the upper shoji frame 2A. Therefore, the force acting on the locking pin 10A due to the external wind pressure is also transmitted to the guide reinforcing block 20, and both receive the external wind pressure. Although the locking pin 10A is in a protruding state from the upper surface of the guide reinforcing block 20, the length to the tip of the locking pin 10A is short. Therefore, deformation of the locking pin 10A is substantially eliminated.

On the other hand, the guide reinforcing block 20
As A moves, it moves along the upper shoji frame 10A. As a result, it is possible to move the locking pin 10A at the correct position while regulating the position of the locking pin 10A (preventing displacement in the left-right direction in FIG. 1).

〔Example〕

Next, the present invention will be explained with reference to the embodiments shown in FIG. 1 and FIGS. 4-6.

A through hole 21 communicating vertically is formed in the center of the guide reinforcing block 20, and the locking pin 10A passes through this through hole 21. A protrusion 22 is formed on one side of the block 20, and this is the upper shoji frame 10A.
The groove 10c is formed by the protruding piece 10a and the stepped wall 10b. block 20
A groove 23 is formed on the other side, into which the lip piece 10d of the upper shoji frame 10A is engaged.

Note that since the lower locking pin 10B is short, there is no need to provide a guide reinforcing block.

Further, it is preferable that the block 20 is made of plastic because of its workability. The block 20 and the locking pin 10A may be integrally formed.

[Effect of idea]

As described above, according to the present invention, the deformation of the locking pin is prevented by the presence of the guide reinforcing block, and the lock can always be smoothly attached and detached.
Prevents rainwater from entering. Further, the block serves as a guide member for the locking pin, and the locking pin can be slid while correctly touching the side surface of the locking receiver.
