Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for preventing the shoji from coming off, which is attached to the sash frame in a sliding manner.

PRIOR TECHNOLOGY Various types of devices have been proposed to prevent the shoji from falling off, which are attached to the sash frame in an easy-to-understand manner. Many of them have drawbacks such as being difficult to handle because once they become stuck, it is difficult to return them to their original state.

The detachment prevention device disclosed in Japanese Utility Model Application Publication No. 58-161069 has first and second elastic pieces that are removable from each other and are attached to the upper frame groove. ) pushes in the second elastic piece, the engagement of the first elastic piece is disengaged, and the first elastic piece is elastically displaced to the stop position. In order to push up the shoji and disengage it from the first elastic piece, the shoji must be lifted upward beyond the vertical width of the first elastic piece, that is, close to its limit. Therefore, in some cases, the shoji may be erected without the first elastic piece (removal prevention piece) being activated due to insufficient lifting of the shoji.

The device for preventing the shoji from falling off disclosed in Japanese Utility Model Application Publication No. 11862/1986 is the same, and in order to release the engagement between the locking plate and the pressing plate, it is necessary to reach the lower side of the locking plate, which has a width in the vertical direction. In order to ensure that the shoji does not come off, the shoji must be pushed up to its upper limit.

Furthermore, in these structures, there are members at the bottom of the upper stile groove, such as the second elastic piece and the pressing plate.
The range in which the shoji can move upward is narrowed,
It tends to make operation difficult.

Problems that the invention aims to solve This invention allows the shoji to operate reliably with a light effort without pushing the shoji up to the limit when attaching it to the sash frame, and also allows the shoji to be moved with a gentle effort. It is an object of the present invention to provide a locking device that can be built in, has a simple structure, and is inexpensive.

Means to solve the problem A device is used to prevent the shoji from coming off, which is attached to the sash frame in a sliding manner.

The retaining device is installed in an upper stile groove that opens upward in the shoji.

The retaining device includes a retaining body and a protruding piece.

One end of the retaining body is supported by a vertical axis, and the other end is biased to rotate toward the other groove wall.
The vertical axis is located close to one groove wall of the upper frame structure.

The upper edge of the retaining body is formed to be lower than the lower edge of the upper rail when the shoji is running, and higher than the required insertion position of the lower edge of the upper rail into the upper stile groove when the shoji is operated.

One end of the protruding piece is attached to the other end of the retainer so that it can rotate between a substantially horizontal state and a substantially vertical state about an axis parallel to both ends of the retainer.

The protruding piece is biased with a force weaker than the biasing force against the retainer so as to return to the horizontal state.

The protruding piece has a length that extends between the retaining body and the other side wall of the upper stile groove in a horizontal state to retract the retaining body from the region where the retaining body is fitted into the upper stile groove of the upper rail.

Function: When the shoji is in the retracted state, the retaining body allows the shoji to be operated against the sash frame, and when the shoji is in the retracted state, it is disabled. The protruding piece maintains the retainer in the retracted state when in the upper position.

Embodiment In FIG. 3, reference numeral a indicates a sash frame, and reference numeral b indicates a shoji. The shoji b is attached to the sash frame a in a sliding manner. Reference numeral 1 is a retaining device. Further, the upper stile 2 of the shoji b is provided with an upper stile groove 2' that is open upward.

As shown in FIGS. 1 and 2, the retaining device 1 includes a retaining body 4 which is disposed within the upper frame groove 2' and has a tension piece 3 projecting from the upper end thereof.

One end of the retainer 4 is pivotally attached to a support 7 which is installed on the upper surface of the mounting member 5 along the side of the groove wall 6 on the outdoor side with a vertical pin 9, and the other end is attached to the upper frame groove 2. ' is horizontally rotatable from one groove wall 6 on the outdoor side to the other groove wall 10 on the indoor side. Further, the other end of the retainer 4 is always urged by a spring 8 provided between the retainer 4 and the support 7 to move toward the groove wall 10 on the indoor side.

In this embodiment, the retaining body 4 and the mounting member 5 are made of hard synthetic resin or the like.

At the top of the other end of the retaining body 4, there is a horizontal pin 1 with one end of a protruding piece 3 made of a thin metal plate or the like having high rigidity and extending along both ends (longitudinal direction) of the retaining body 4.
1, and is movable in a range from a substantially vertical state along the retainer 4 to a substantially horizontal state with the other end directed toward the indoor groove wall 10.

The protruding piece 3 is always urged upward via a spring 12 provided between it and the retainer 4. The protruding piece 3 is prevented from rotating beyond the horizontal position by having a portion of its one end abutting against the upper surface of the stopper 4, thereby setting the above-mentioned horizontal state. Further, the biasing force of the spring 12 against the tension piece 3 is made weaker than the biasing force of the spring 8 against the retaining body 4.

The retainer 4 is attached by fixing the mounting member 5 to the bottom of the groove of the upper stile 2 with screws 13, with the support 7, that is, one end of the retainer 4 facing the outdoor side. When the retaining body 4 is pushed toward the outdoor side against the bias of the spring 8 in this attached state (FIG. 4), the protruding piece 3 at the other end is pushed against the bias of the spring 12. It rotates upward and assumes a horizontal state, and its tip abuts and engages with the inner surface of the groove wall 10 on the indoor side. That is, the protruding piece 3 is attached to the indoor side wall 10 of the upper stile groove 2' and the retainer 4.
This prevents the other end of the retaining member 4 from rotating toward the indoor side (Fig. 1, Fig. 4 A).
As a result, the retaining body 4 is located along the groove wall 6 on the outdoor side in the upper frame groove 2', and the area where the upper rail 17 fits into the upper frame groove 2' (with a certain width and depth) during the maintenance operation. It will be in a retracted state outside of the This area is marked A-B in Figure 3.
It is between.

A shows upper rail 1 when shoji b is attached to sash frame a and can be run (when the shoji is running)
7, and B is the minimum necessary position where the lower edge of the upper rail 17 is inserted into the upper stile groove 2' for safety when installing the shoji b to the sash frame a. (required insertion position).

In this state, when the protruding piece 3 is pushed downward by an external force, the retainer 4 loses its support, and its tip collides with the inner surface of the groove wall 10 on the indoor side under the force of the spring 8. Move indoors until
It stops diagonally crossing the upper stile groove 2' (Fig. 4b).

In this state, the retainer 4 is in the area A-
Even if you try to operate the shoji b in the range B, the lower edge of the upper rail 17 will collide with the upper edge of the retainer 4, and the shoji b cannot be moved upwards enough. It cannot be removed from the sash frame a. The retaining body 4 is in a retained state within the upper frame groove 2'.

In other words, the upper edge of the retainer 4, when attached to the upper stile groove 2', is lower than the lower edge position A of the upper rail 17 when the shoji is running, and the lower edge of the upper rail when operating the shoji is lower. It is formed at a position higher than the required insertion position B.

In other words, the upper edge of the retainer 4 is located below the lower edge of the guide rail 17 when the shoji is erected, and the vertical distance between the two is sufficient to remove the lower stile from the lower frame. smaller than the required vertical movement.

Now, in order to attach the shoji b, which is equipped with the retaining device 1 of the present invention on the upper stile 2, to the sash frame a, first confirm that the retainer 4 is in the retracted state, and then move the sash frame The upper stile 2 of the sash b is engaged with the upper rail 17 of the upper frame 16 of a, and is pushed up to the extent that the lower stile can be placed on the sash lower frame, although not shown. Then, the protruding piece 3 of the retaining body 4 collides with the lower edge of the upper rail 17 and is still moved upward, so that the retracted state of the retaining body 4 is easily released, and the retaining body 4 is moved upward. The tip of the guide rail 17 comes into contact with the outdoor side surface of the guide rail 17, and is urged toward the indoor side by the spring 8. Next, when the lower stile of the shoji b is fitted into the frame area of the sash and the shoji is lowered onto the lower frame, the upper edge of the retainer 4 becomes lower than the lower end of the upper rail 17 and engages with the upper rail 17. The combination is resolved. Therefore, the retaining body 4 is reliably rotated toward the indoor side by the biasing force of the spring 8, and becomes the aforementioned retaining state in which it is obliquely located within the upper stile groove 2'. In this case, the upper edge of the retaining body 4 is higher than the required insertion position B during the maintenance operation, so even if the shoji is lifted, the lower stile cannot be taken out of the frame area of the sash frame a, and Shoji cannot be removed.

To remove the mounted shoji b from the sash frame a, as shown in FIG. to press against. Then, the protruding piece 3 immediately returns to the horizontal state by the spring 12, and the other end abuts against the indoor side groove wall 10 of the upper stile groove 2', and even if the pushing tool 14 is pulled out, the retainer 4 remains in the retracted state. In this state, lift the shoji and remove the lower stile from the frame area of the lower sill using the Kendon operation. Upper rail 17 during Kendon operation
The protruding piece 3 is pushed down by the lower edge, and the other end of the retaining member 4 moves toward the indoor groove wall 10, but at this time, the lower edge of the upper rail 17 is already lower than the upper edge of the retaining member 4. Since it is fitted downward, the retaining body 4 does not go around below the upper rail 17, and the shoji b can be lifted as much as necessary for the easy operation.

In addition, if the tension piece 3 is attached to the upper part of the tip of the stopper body 4 as in the embodiment, when installing the shoji b, the lower edge of the upper rail 17 and the tension piece 3
The timing of contact is earlier, and the pusher piece 3 can be operated more reliably than when this contact occurs at the end of pushing up the shoji.

In the present invention, the retaining body 4 may be retracted to either the outdoor side or the indoor side within the upper stile groove 2'. However, it is preferable to install it outside the room for security reasons. In addition, in the embodiment, the retaining body 4 and the tension piece 3 are rotatable by pivoting using pins 9 and 11, and biased by springs 8 and 12. It can also be achieved without using pins or springs by taking advantage of its flexibility and elasticity. Furthermore, the shape of the retaining body and the tension piece,
The means for maintaining the protrusion piece upward is not limited to those in the embodiment.

Effect The abutting engagement between the protruding tension piece and the groove wall can be easily removed by pushing the protruding tension piece with the lower edge of the upper rail, and as a result, the retaining body immediately shifts to the retaining state. Therefore, operation is reliable.

Since the functional parts of the retaining body and the tension pieces are not located in the low part of the upper stile groove, there is plenty of room for adjusting the vertical movement when installing and removing the shoji, making it easy to operate.
