Description

[Detailed Description of the Invention] The present invention relates to a shoji slip-off prevention device that prevents a shoji housed in a window frame from coming off from the window frame due to strong winds or the like.

Conventionally, this type of shoji removal prevention device was as follows:
As disclosed in Japanese Utility Model Publication No. 51-6953, a removal stopper having an insertion part having a long hole extending vertically and a removal prevention part protruding above the insertion part,
It is known that the shoji is inserted into the hollow part of the vertical stile at the upper end of the stile and fixed to the vertical stile via a screw inserted into the elongated hole.

With this structure, after storing the shoji in the window frame, move and adjust the stopper upwards so that it faces inside the upper frame, and in this state, fix the stopper to the window frame with screws. can be prevented from separating from the window frame.

However, with this type of device, it is necessary to adjust the stopper and fix the screws after the shoji is stored in the window frame, so it is necessary to adjust the stopper and fix the screws, so it is necessary to adjust the stopper and fix the screws. Occasionally, the above-mentioned operation is forgotten or mistakenly performed, and in this case, the removal stopper attached to the shoji stile no longer functions.

As a result, when the shoji housed in the window frame is subjected to wind pressure due to strong winds, the shoji may bend in the direction of the indoor/outdoor direction and detach from the window frame.

In other words, with the above-mentioned retaining device, when the shoji is stored in the window frame, the retainer gets in the way, so it must be moved downward, and after being stored, it must be moved upward and fixed with screws, making it difficult to store the shoji. If you forget or neglect to adjust the upward movement of the stopper or fix the screws afterwards, the shoji may come off from the window frame, which is undesirable.

Therefore, a detachment preventing device that solves the above-mentioned problems is disclosed in Japanese Utility Model Publication No. 55-624.

In other words, the rotary body is installed in the groove of the upper frame so that it can freely rotate between a position where it interferes with the shoji upper stile and a position where it does not interfere, and is biased to rotate toward the interference position, and the rotation of the rotary body to the interference position is prevented. An elastic body is provided to prevent
The elastic body is elastically deformed when the shoji is hung in the groove of the upper frame of the shoji using the Kendon method, and when the shoji is completely housed in the window frame, the rotating body automatically rotates to the interference position to restrict the upward movement of the shoji. This is a device that prevents the shoji from coming off the window frame.

With this structure, when the shoji is housed in the window frame, it automatically performs the function of preventing the shoji from coming off, which eliminates the above-mentioned problems and provides an extremely practical device for preventing the shoji from coming off.

However, with this structure, after the shoji has been stored, the rotating body can be easily rotated to a non-interfering position without the need for special tools, and the function to prevent the shoji from coming off can be released. It is dangerous that the locking function may be intentionally canceled by a third party.

In particular, if it is installed on the window of a hospital, library, school, or other public institution building where an unspecified number of people go in and out, the anti-removal function may be canceled by an unspecified number of third parties. This is extremely dangerous as it is easy for this to occur.

In addition, when installed in the windows of elementary and junior high school buildings, the rotating body attached to the upper frame is exposed to the outside and can be easily seen when the window is open, so children may play with the rotating body out of curiosity. This is not desirable as the locking function may be canceled due to mischief.

Therefore, a device to prevent the shoji from coming off when installed on the windows of buildings such as public institutions where a large number of unspecified third-party people come in and out is a device that automatically prevents the shoji from coming off when the shoji is hung and stored. There is a need for a shoji sliding door retaining device that has a retaining function and cannot be released without using some kind of tool.

The present invention was developed in view of the above points, and its purpose is to automatically prevent the shoji from coming off by hanging and storing the shoji on the window frame, and to prevent unspecified third parties from entering the room. To provide a retaining device which prevents the retaining function from being released by people in a privileged position and which allows a person concerned to release the retaining function by a simple operation without using a simple tool.

The present invention will be explained below based on embodiments shown in the drawings.

In Figures 1 to 3, 1 is the upper frame of the window;
2 is the upper stile of the shoji, 3 is the vertical stile of the shoji, and 4 is the glass. A long operating rod 10 is provided in the groove 5 on the upper side of the upper stile 2 in the longitudinal direction, and a stopper 20 and a braking member 30 are provided spaced apart in the longitudinal direction of the upper stile 2.

The operating rod 10 has a length that is almost the same as the width of the shoji, and is L-shaped with a bottom member 11 and a vertical member 12, and the bottom member 11 is
A vertical side member 12 is provided in contact with an intermediate wall 6 of the upper stile 2 and a vertical wall 7 of the upper stile 2. Notches 13 and 14 are formed in the bottom member 11 of the operating rod 10, and a notch 15 is formed in the vertical member 12 in correspondence with the notch 14,
A pull-out hole 16 is formed at one end in the longitudinal direction. This operating rod 10 is protruded to the side of the pull-out hole 16 when the shoji is hung from the window frame and when the shoji is removed from the window frame.

Of the front surface 17 and rear surface 18 of the bottom member 11 of the operating rod 10 that constitute the notch 13, the operating rod 1
The front surface 17 located on the drawer side (front) of 0 is a concave inclined arc surface with the vertical side member 12 side located at the front and the opposite side, that is, the vertical wall 8 side of the upper stile 2 located at the rear. The other rear surface 18 is a flat surface extending in the normal direction of the vertical wall 7, and the vertical wall 8 side is an arcuate surface extending forward from the end of the flat surface.

The stopper 20 has a flat base 21 and a stop 22 rising from one end of the base.
The notch 13 of the operating rod 10 is shaped like a letter.
It is rotatably attached to the intermediate wall 6 of the upper stile 2 by a pin 23 at a location corresponding to ing.

The front end surface 24 of the base 21 on the front surface 17 side is an inclined surface along the surface 17, and the rear end surface 24 on the rear surface 18 side is an inclined surface along the surface 17.
5 is a plane corresponding to the rear surface 18 and an arcuate surface.

When the end of the operating rod 10 on the pull-out hole 16 side protrudes from the shoji as shown in FIGS. It is located parallel to the longitudinal direction of the frame 2. Further, when the operating rod 10 is retracted into the shoji, the stop portion 22 is inclined with respect to the longitudinal direction of the upper stile 2, as shown in FIG.

Note that the surface 18 may be an inclined plane like the surface 17.

The braking member 30 is a leaf spring bent in a Z shape, and with one piece 31 located in the notch 14 of the operating rod 10, the other piece 32 is attached to the upper frame 2 with a screw 33.

abuts against the flat surface of the rear surface 18 of the bottom member 11 of 0;
As the operating rod 10 moves further, the stopper 20 is rotated counterclockwise in FIG.
As a result, the stop portion 22 of the stopper 20 is positioned parallel to the longitudinal direction of the upper stile 2 on the vertical wall 8 side of the upper stile 2.

It is preferable to provide the stoppers 20 at a plurality of locations in the longitudinal direction of the upper stile 2, as this will ensure the ability to prevent the stoppers 20 from coming off. Further, the braking member 30 is connected to the operating rod 1.
It may be of a type in which the bottom member 11 of 0 is pressed against the upper frame 2.

As described above, the present invention is provided movably in the longitudinal direction in the groove on the upper side of the upper stile, is formed in an L-shape by a bottom member and a vertical member, and has a concave inclined arc surface on the bottom member. The shoji has a notch having a front surface that is flat and a rear surface that is a flat surface on the side of the vertical side and an arc surface on the opposite side, and a long operating rod that can be retracted from the side of the shoji, and a long operating rod that is located within the notch. It is rotatably provided in the concave groove of the upper stile, has a triangular shape with the sides on the side of the vertical member sloping, the rear end surface has a plane and an arcuate surface along the rear surface, and the tip surface slopes along the front surface. Since the locking device consists of a flat base and a stopper having a stopper rising from one end of the base, the locking device can be set in the locking position simply by moving the operating rod in and out of the shoji. Therefore, by hanging and storing the shoji on the window frame, it automatically functions to prevent the shoji from coming off, and it is also possible for an unspecified number of third-party people to prevent the shoji from coming off. The locking function will not be released,
Moreover, the person concerned can release the locking function with a very simple operation using a simple tool.
