Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for preventing sliding sliding windows from coming off.

Conventional technology A sliding window is a type of sliding window in which the shoji is built into the window frame in a vertical manner and moved inward to open and close. The shoji comes off the window frame.

For this purpose, as shown in Japanese Utility Model Application Publication No. 58-167181, a retaining piece is provided on the upper stile of the shoji so as to be movable up and down, and a sliding member is provided to rotate this outer retaining piece upward. The working rod is provided to be slidable, and when installing the shoji, the working rod is made to protrude laterally from the upper stile, and the sliding member is separated from the retaining piece and rotated downward, thereby closing the window of the shoji. The lifting stroke within the frame is increased so that the shoji can be erected in an up-and-down manner, and when the shoji is moved in the closing direction and butts against the jamb, the working rods will hit the jamb and close the upper stile. A retainer that is pushed inward, engages the sliding member and the retainer piece, rotates the retainer piece upwards, reduces the lifting stroke of the shoji within the window frame, and prevents the shoji from coming off. The device is known.

With a sliding window equipped with such a device to prevent the shoji from coming off, the shoji can be prevented from coming off by placing the shoji inside the window frame and closing it. It is safe because it will not come off.

Problems to be Solved by the Invention With such a retaining device, since the retaining piece, sliding member, and working rod are provided on the upper stile, it is necessary to perform special processing on the upper stile, which is troublesome. ,
The weight of the shoji increases, making it difficult to open and close it smoothly.Furthermore, the shoji needs to be moved to the fully closed position, so the in-plane width of the shoji changes and the distance it takes to close completely. If the shoji are different, the length of the action rod, the dimensions of the sliding member, the mounting position of the retaining piece, etc. must be changed accordingly, resulting in incompatibility, and the installation work must be adjusted to fit the width of the shoji in the in-plane direction. It becomes troublesome because you have to change the position.

Therefore, the present invention does not require troublesome special processing on the upper stile of the shoji or increase the weight of the shoji, and even if the in-plane width of the shoji changes, parts of the same size can be placed in the same position. To provide a device for preventing a shoji from falling off for a sliding window, which can prevent the shoji from coming off by being attached to the shoji.

Means and action for solving the problem A case body equipped with an operating rod having an abutment piece and a retaining member is attached to the upper frame, and the retaining member is opposed to the upper part of the shoji and is in a retaining posture and a non-receiving posture. In addition to being able to freely swing up and down in the posture and always maintaining the non-removal posture, the actuating rod is formed with a regulating portion that comes in contact with the upper part of the non-removal prevention member to prevent it from swinging to the non-removal prevention posture, and the contact piece is When the shoji comes into contact with the matching stile, the operating rod slides and the regulating part comes into contact with the top of the member to prevent it from coming off.If the shoji is built without any member on the top of the shoji and moved to the closed side, it will not come off. This prevents the shoji from coming off by preventing the member from swinging into a non-removal-preventing position.

Embodiment As shown in FIG. 1, a sliding window is a window frame 5 consisting of an upper frame 1, a lower frame 2, and left and right frames 3 and 4.
The outer shoji A and B are built in different sliding ways.
Each shoji has upper stile 6, 7, lower stile 8, 9, and stile 1.
Glasses 14 and 15 are mounted inside a rectangular frame assembly consisting of 0 and 11 and doorstop frames 12 and 13. A shoji removal prevention device C is attached at a position opposite to 11.

As shown in FIG. 2, the shoji removal prevention device C is
Case body 20 and a pair of retaining members 21, 21
The case body 20 has a plate shape having a predetermined width, thickness, and length, and a longitudinal groove 24 is formed in the center of the upper surface in the width direction. A pair of protruding pieces 25 and 26 are integrally formed at intervals on both sides of the lower surface in the longitudinal direction, respectively, and constitute a mounting part 27 of the retaining member 21, and a slit-shaped part is formed on both sides of the longitudinal center of the groove part 24. A pair of openings 28, 28
is formed, and an opening 29 is formed in the center of the bottom, and the bottom of the groove 24 has an uneven shape in the longitudinal direction, with a first step 30 facing one side and a second step 31 facing the other side. It has been formed.

The retaining member 21 is vertically swingably supported by a pin 32 between a mounting portion 27, that is, a pair of protruding pieces 25 and 26, and an upper portion 21a is exposed in the groove portion 24, and one end portion 21b is attached to the matching frame. A stopper 33 is formed at the other end 21c facing the upper part, and due to its own weight, the stopper 33 comes into contact with the lower part of the case body 20, and is held in a position where the lower surface 21d is horizontal to prevent it from coming off.

The operating rod 22 has a long plate shape that fits into the groove 24, and has a pair of restricting portions 34, 34 that contact the upper portion 21a of the retaining member 21, and an abutment piece 35 is fixed to the lower surface of the intermediate portion. At the same time, one end is inclined downward so as not to come into contact with the upper frame, and a bent piece 36 is formed.

The upper windstop plate 23 has a plurality of vertical plates 38 integrally formed at the lower part of the horizontal plate 37, and a pair of hook pieces 39 at the upper part.
39 are integrally formed to constitute a groove 40, and a notch 41 through which the abutment piece 35 is inserted is formed in a portion of the horizontal plate 37 facing the groove 40, as shown in FIG. The upper windshield plate 23 is attached to the case body 20 by engaging the pair of hooks 39, 39 into the pair of slit-shaped openings 28, 28 of the case body 20 in a snap manner. The operating rod 22 is slidably fitted into the groove 40. Note that the upper windstop plate 23 is made of an elastic material such as resin,
The operating rod 22 is held so that it does not wobble.

As shown in FIG. 4, the upper frame 1 has inner and outer upper rails 51, 52 integrally formed on a horizontal plate 50, and projecting pieces 51a, 52a are provided at the bases of the inner and outer upper rails 51, 52. are formed, and these projecting pieces 51a,
52a and the horizontal plate 50 by inserting the both sides 20a, 20a of the case body 20 from the longitudinal direction and caulking them, or inserting screws into the case body 20 to tighten the horizontal plate 5.
A retaining device C is attached to the upper frame 1 by touching the upper frame 1 and moving downward.

As shown in FIG. 1, with the operating rod 22 protruding to one side from the case body 20, that is, in contact with the second step portion 31, the regulating portion 34 is attached to the upper portion 21a of the retaining member 21. If the contacting position is set, as shown in FIG. 7, the retaining member 21 is prevented from swinging counterclockwise about the pin 32, and is held in a retaining position with the lower surface 21d being approximately horizontal. Therefore, as shown in FIG. 4, the upper part of the shoji faces the lower surface 21d of the retaining member 21, so that the lifting stroke of the shoji becomes small and the shoji does not come off.

Further, as shown in FIG. 8, the operating rod 22 is pushed into the case body 20 and brought into contact with the first step part 30, and the regulating part 34 is removed from the upper part 21a of the retaining member 21.
If the shoji is separated from the shoji, the retaining member 21 can be swung counterclockwise to the non-receiving position shown by the imaginary line as shown in FIG.
Since the shoji can be moved further upward after contacting the lower surface 21d of the shoji 1, and the lifting stroke of the shoji can be increased, the shoji can be built into the window frame in an up-and-down manner.

At this time, the shoji is installed not in a completely closed state but in a slightly open state to prevent the abutting pieces 35 from interfering with the matching frame 11.

After the shoji is installed, the shoji is moved in the closing direction, and as shown in FIG. 5, the connecting frame 11 interferes with the abutment piece 35, and the operating rod 22 is moved together with the shoji, as shown in FIG. 1. The regulating part 34 is placed in contact with the upper part 21a of the retaining member 21, thereby preventing the shoji from coming off as described above, and by moving the shoji to the closing side without any special operation, the shoji can be closed. It is possible to prevent it from coming off.

In addition, since the abutment piece 35 interferes with a part of the matching frame 11 when opening and closing the shoji, a notch 11a is formed in that part so that the abutting piece 35 can interfere with the meeting frame 11 when opening and closing the shoji. It is designed not to interfere with frame 11.

In the embodiment, after the indoor shoji A and the outdoor shoji B are installed, the outdoor shoji B is moved to the closing side and the contact piece 35 is brought into contact with the matching frame 11 of the outdoor shoji B. However, the contact piece 35 may be brought into contact with the matching frame 10 of the indoor shoji A.

Effects of the invention If the operating rod 22 is set at a position where the regulating portion 34 separates from the retaining member 21, the retaining member 21 can be swung to the non-receiving position, so the lifting stroke of the shoji can be increased and the shoji can be moved vertically into the window frame. If you move the shoji to the closed side in that state, the contact piece 35 will come into contact with the matching frames 10 and 11, the operating rod 22 will slide, and the regulating part 34 will move the stopper member 21. Since the shoji is prevented from swinging into the non-removal-preventing position in contact with the shoji, it is possible to prevent the shoji from coming off.

Further, since the case body 20, the retaining member 21, the operating rod 22, etc. are attached to the upper frame 1 side, and no members are attached to the upper part of the shoji, there is no need to perform any special processing on the upper part of the shoji. You can open and close the shoji smoothly without adding too much weight.

In addition, since the abutting pieces 35 are brought into contact with the matching frames 10 and 11 and the operating rods 22 are slid, they are prevented from coming off, so even if the in-plane dimensions of the shoji differ, each member can be of the same size and It is sufficient to mount it at a predetermined position using the matching frames 10 and 11 as a reference, which provides compatibility and facilitates the installation work.
