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 retainer 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 screen housed in the window frame is subjected to wind pressure due to strong winds, the shoji screen bends in the direction of the indoor/outdoor direction and detaches from the window frame.

In other words, with the above-mentioned retaining device, the retainer gets in the way when storing the shoji in the window frame, so it must be moved up and down, and after being stored, it must be moved upward and fixed with screws, making it difficult to store the shoji. If you later forget to adjust the upward movement of the stopper or fix the screws, or if you are lazy, 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 rotating 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 to the interference position, and the rotation of the rotating body to the interference position is prevented. An elastic body is provided to prevent
When the shoji is hung in the groove of the upper frame using the Kendon method, the elastic body is elastically deformed, 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 storing the shoji, the rotating body can be rotated to a non-interfering position without using any 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 window frame, and to prevent unspecified third parties from To provide a detachment preventing device which prevents the detachment preventing function from being canceled by people in a position and which allows the person concerned to cancel the detachment preventing function by a simple operation even when using a simple tool.

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

In the figure, 1 is the upper frame of the window, 2 is the upper stile of the shoji,
3 is a vertical stile of the shoji, 4 is glass, and 5 is a corner block provided at the connection between the upper stile 2 and the vertical stile 3. In the groove 6 on the upper side of the upper stile 2, a long operating rod 10 is provided in the longitudinal direction, and a stopper 20 and a brake member 30 are also provided.

The operating rod 10 is a plate-shaped body having a length approximately the same as the width of the shoji, and is provided so as to come into sliding contact with the vertical wall 7 at the upper part of the upper stile 2. A pair of notches 11 and 12 are formed adjacent to each other in the longitudinal direction of the operating rod 10, and a notch 13 is formed at a location slightly away from the notch 11. Furthermore, a pull-out hole 14 is formed at one end. This operating rod 10 has a pull-out hole 13 when the shoji is hung on the window frame and when the shoji is removed from the window frame.
is projected laterally from the vertical stile 3 of the shoji.

The stopper 20 includes a flat base 21 and an inverted L-shaped stop 22 rising from one end of the base.
It has a pair of protrusions 23 and 24 that protrude horizontally from the other end of the base 21, and the protrusions 23 and 24 are located in the longitudinal direction of the upper stile 2 and can be operated. The intermediate wall 8 of the upper stile 2 is placed so as to face the pressing part 15 between the notches 11 and 12 of the stile 10.
It is rotatably attached to a base 26 screwed to the base 26 by a pin 27 about a location corresponding to a recess 25 separating the protrusions 23 and 24.

The protrusions 23 and 24 are spaced apart by a width that is approximately the same as the thickness of the pressing portion 15 of the operating rod 10, and the protrusion 23
and 24 have surfaces on the side of the recess 25 that are inclined surfaces.

Incidentally, instead of attaching the stopper 20 to the upper stile 2 via the base 26, it may be supported directly on the upper stile 2 using rivets or the like.

This stopper 20, as shown in FIG.
When the end of the operation rod 10 on the pull-out hole 14 side protrudes from the shoji, the protrusion 23 comes into contact with the pressing part 15, the protrusion 24 enters the notch 12, and the stop part 22 contacts the vertical part of the upper stile 2. It is located parallel to the longitudinal direction of the upper stile 2 on the wall 9 side. Further, when the operating rod 10 is retracted into the shoji, the stopper 20 is stopped by the protrusion 24 coming into contact with the pressing part 15 and the protrusion 23 entering the notch 11, as shown in FIG. The portion 22 is inclined with respect to the longitudinal direction of the upper stile 2.

The braking member 30 is a leaf spring bent in a Z shape, and the other piece 32 is attached to the intermediate wall 8 of the upper stile 2 with screws 33 while one piece 31 is located in the notch 13 of the operating rod 10. It is being In this braking member 30, the length of the piece 31 is almost the same as the thickness of the operating rod 10, and by pressing the bottom part of the notch 13 with this piece 31 and urging the operating rod 10 against the upper frame 2, , the movement of the operating rod 10 relative to the upper stile 2 is braked.

As shown in FIGS. 1 and 2, this retaining device causes the pull-out hole 14 side of the operating rod 10 to protrude from the shoji. As a result, the stopper 20 has the protrusion 23 in contact with the pressing part 15 and the protrusion 24 in the notch 1.
2, and the stop part 22 is attached to the vertical wall 9 of the upper stile 2.
It is positioned parallel to the longitudinal direction of the upper stile 2 on the side and is in a state where the retainer is released.

In this state, the shoji is hung on the window frame, then the shoji is closed, the vertical frame 3 of the shoji is pressed against the vertical frame of the window, and the operating rod 10 is sunk into the shoji.
As the pressing part 15 moves into the recess 25 and then along the slope of the protrusion 24, the stopper 20 is rotated about the pin 27, and as a result, as shown in FIGS. As shown in FIG. 5, the protrusion 24 contacts the pressing part 15, the protrusion 23 enters the notch 11, and the stop part 22 is located at an angle with respect to the longitudinal direction of the upper stile 2 to prevent it from coming off. becomes the state of

When the tip of a screwdriver or the like is inserted into the pull-out hole 14 of the operating rod 10 and the operating rod 10 is pulled out in the state of the retainer set, the pressing portion 15 moves to the recess 25 as the operating rod 10 moves. Then, as the stopper 20 moves along the inclined surface of the protrusion 23, the stopper 20 is rotated about the pin 27 in the opposite direction to that described above, as shown in FIGS. 1 to 3.
The protrusion 23 contacts the pressing part 15, the protrusion 24 enters the notch 12, and the stopper 22 is located parallel to the longitudinal direction of the upper stile 2 on the vertical wall 9 side of the upper stile 2 to prevent it from coming off. It will be in a released state.

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 stopper from coming off. Further, the operating rod may have an L-shaped cross section so that the braking member presses the bottom member of the operating rod.

It is provided so as to be movable in the longitudinal direction in the groove on the upper side of the upper stile, and has one notch part and the other notch part of a pair that are adjacent to each other in the longitudinal direction with the pressing part at the center. a long operation rod that can be retracted and retracted; and a protrusion that is rotatably provided in the groove of the upper stile and that has one protrusion and another protrusion that protrude toward the notch at the other end; The protrusions protrude more than the other protrusion, and the protrusions are spaced apart by a width that is approximately the same as the width of the pressing part. a base having a concave portion with a tapered portion formed toward the top; a stopper having a stop portion rising from one side end of the base; and a stopper provided in the concave groove of the upper stile and configured to move the operating lever relative to the upper stile. Since the locking device consists of a braking member made of a leaf spring that applies a brake to By hanging and storing the shoji, the function of preventing the shoji from coming off is automatically performed, and the function of preventing the shoji from coming off is prevented from being canceled by an unspecified number of third party persons, and the function of preventing the shoji from coming off is prevented from being canceled by an unspecified number of third parties.
