Description

[Detailed Description of the Invention] The present invention relates to a shoji falling prevention device, and more particularly to a device that can reliably prevent a sliding door shoji from falling off a window frame.

Conventionally, in sliding doors, an extra gap has been provided between the shoji and the window frame due to construction requirements, but on the other hand, because of this gap, accidents have occurred where the shoji is lifted carelessly and falls off the window frame. was.

In order to prevent such falling accidents, generally, as shown in Fig. 1, a stopper 1 is attached to the upper end of the short root of the outer shoji so that it can move up and down. 1 to the lower position to prevent it from interfering with the erection work, and then, after the shoji is erected, as shown in Figure 2, push the retainer 1 upward to the upper position and hold it in place. Currently, the shoji is prevented from falling off by suppressing the movement.

However, there have been cases where this retainer slides downward due to shocks when opening and closing the shoji and no longer functions as a normal retainer, but even in this situation, there is no problem in opening and closing the shoji. Therefore, the user could not detect the abnormality, and there was a risk of the shoji falling off unexpectedly.

As a result of repeated efforts to eliminate the above-mentioned dangers, the inventor of the present invention has changed the current removal stopper that adjusts the movement in the vertical direction.
They discovered that by making the instrument rotatable, the user could detect any abnormalities in the instrument's installation in advance, and completed the present invention.

If the present invention is explained based on the drawings, the retaining piece 2 is
When the shoji is erected, it protrudes from the upper end of the short roots 5 on the door stop side to prevent it from coming off, and when it falls sideways, it protrudes from the short roots 5 to the side, preventing the shoji from completely closing.
This is a shoji fall prevention device in which one end of the retaining piece 2 is rotatably attached to the upper part of the short root 5 with a screw 13 or the like.

In the device of the present invention, the retaining piece 2 may be rotatably attached directly to the top of the short root 5 on the door stop side, but one end of the retaining piece 2 is fixed inside the box body 3 with openings on the top and one side. This box body 3 is fixed to the upper part of the short root 5 with screws 13 or the like so that the open side of the box body faces the short frame 12 side of the window frame.

The fixing position of the retaining piece 2 attached to the top of the short root 5 is the fourth
As shown in the figure, it should be designed so that it has a retaining effect when standing up, and normally projects sideways from the short roots 5 when it rotates and falls sideways.

The installation of a shoji screen to which the device of the present invention is attached is carried out by first fitting the retaining piece 2 into the window frame in a laid-down state, and then rotating the retaining piece 2 to stand it up.

If the shoji built in this way is opened and closed for a long period of time,
The upright retaining piece may gradually fall down and no longer function as a retainer.

However, if the retaining piece falls sideways, it will protrude laterally from the short roots of the shoji, so when the shoji is closed, the retaining piece will hit the window frame and will not close completely. Therefore, the user can immediately sense that the fall prevention device is not functioning.

Note that the rotating state of the retaining piece is inappropriate because it will not function as a retainer if it can rotate too freely.
On the other hand, if the shoji is completely fixed, it will be impossible to attach or detach the shoji to the window frame.

Therefore, it is preferable to adjust the rotational state so that it does not move due to the impact when opening and closing, and requires human power to rotate.

Furthermore, a supporting protrusion 8 may be provided in order to maintain the erected state of the retaining piece.

In this case, when removing the shoji, the protrusion 8 is deformed by pressing or the like, and the retaining piece 2 is turned sideways so that the shoji can be easily operated.

The shape of the retaining piece 2 in the fall prevention device of the present invention is generally approximately rectangular, but there is no particular limitation.

For example, if the upper part of the retaining piece is shaped so that it does not fall over a certain angle, even if the retaining piece is about to fall diagonally and protrudes to the side of the short root 5, it will be difficult to prevent it from falling over when closing the shoji. The obliquely protruding retaining pieces come into contact with the bag frame and gradually stand up, and when the shoji is completely closed, the retaining pieces also completely stand up at the same time to exhibit a retaining action.

Therefore, the retaining piece always functions normally.

In the case of a shoji of the type that fits into the window rails 10 as shown in FIG. What is necessary is just to cut out the position where the upper rail 10 hangs on the upper side of the opposing side.

Providing such a notch 11 is advantageous because the box body 3 itself also acts as a stopper for the upper frame rail 10 and the upper stile of the shoji.

In the above-mentioned type of shoji, the mounting position should be selected so that the retaining piece 2 comes close to the bottom end of the upper Azusa rail when it is erected.

On the other hand, in the case of a type of shoji that fits into the groove between the rails of the window sill as shown in Figures 3 to 5, a notch as described above is provided in the box body 3 housing the retaining piece 2. Although it is not necessary, the position of the retaining piece above the short root of the shoji should be selected so that when the shoji is erected, it will protrude above the top of the short root of the shoji and come close to the bottom surface of the upper shoji.

The fall prevention device of this invention is usually attached to the top of the short root on the side of the shoji and doorstop, but even if it is attached to the top end of the stile or other parts, if it no longer works to prevent it from falling off, it will protrude from the shoji, creating a dangerous situation. can be easily detected.

In particular, if the retaining piece is painted in a conspicuous color, it will be easier to detect.

As described above, the fall prevention device of the present invention is extremely effective as a device that can prevent shoji sliding doors from falling off.
