Description

[Detailed description of the invention] This invention relates to a device to prevent the shoji from falling off in a sash, and without the use of any special tools, the device automatically becomes locked when the shoji is opened and closed once at the end of construction. The present invention proposes a locking device that is set so that the locking device is set such that the locking device is set so that the locking device is set so that the locking device can visually confirm that the locking state has been reached.

<Background of the invention> In the conventional anti-removal device, a nylon block or the like is attached to the upper stile of the outer shoji, and this nylon block is secured with a screw through a long hole.By loosening the screw and moving the nylon block downward, the nylon block is A large gap is formed between the block and the upper frame, and by forming this gap, the shoji can be pushed up toward the upper frame, and the shoji can be removed from the window frame. Therefore, removing the shoji from the window frame requires a tool to loosen the screws, which is troublesome.

Also, when the shoji is installed in the window frame, the nylon block must be raised to the specified position and the screws must be tightened. If this step is neglected, the shoji may come off at some point, which is especially dangerous in high-rise buildings.

<Purpose of the invention> The purpose of this invention is to be able to set the shoji in a locked and unlocked state without using any tools, and to open and close the shoji once it is installed. To provide a locking device that can automatically return to a locked state.

An embodiment of this invention will be described below in detail with reference to the drawings.

<Summary of the invention> In this invention, rotating levers are attached to both ends of the upper stile of the shoji. This rotating lever has a protrusion that faces toward the upper frame of the window frame, and this protrusion faces a protrusion formed on the upper frame to prevent it from coming off. When erecting the shoji or removing the shoji from the window frame, the opposing relationship between the protrusions and the ridges is removed by rotating a lever, thereby making it possible to push the shoji up toward the upper frame. It is.

A downward protrusion is attached to the upper frame, and the structure is such that when the shoji is once closed during construction, the downward protrusion engages with the lever, and the lever is operated to the locking position. .

Therefore, according to this invention, even if one forgets to set the shoji to the non-removable state during construction, the shoji can always be set to the non-removable state once the shoji is moved to the closed window position.

<Embodiment of the invention> Fig. 1 shows the whole of a shoji shoji equipped with a shoji slip-off prevention device according to this invention. In the figure, 101 is a window frame, 10
2 is a shoji screen. In this example, the shoji 102 is assumed to be an outer shoji.

In this invention, levers 104 and 105 are attached to both ends of the upper stile 103 of the shoji 102. In other words, the levers 104 and 105 are installed in opposite directions so that the free turning ends are located close to the door stop surface of the vertical stile 201 of the shoji 102, as shown in FIG. It is mounted so that it can be rotated in any direction. An upward protrusion 202 that protrudes upward is formed at each free rotation end of these levers 104, 105. In addition, the tips of the free rotation ends of the levers 104 and 105 are attached so that they can be seen on the door stop surface of the shoji 102. On the other hand, as shown in FIG.
01, a protrusion 302 is formed over the entire movement range of the shoji 102. Although such a protrusion 302 does not exist in the upper frame material commonly used in the past, this protrusion 302 is provided in this invention. Although this example shows a case in which it is formed integrally with the upper frame 301, the protrusion 302 may be formed by attaching another member. Furthermore, although the figure shows a case in which the protrusions 302 protrude vertically from the top plate of the upper frame 301, the protrusions 302 protrude horizontally as shown by dotted lines.
03 can also achieve the purpose of this invention.

Furthermore, two blocks 106 (see FIG. 1) made of, for example, nylon resin are attached to the upper frame 301. This block 106 is provided within the movement range of the upward protrusion 202 provided on the shoji, and
As shown in FIG. 4, it has an inclined surface 401 at both ends and a downward protrusion 402 that protrudes downward, and this downward protrusion 402 is formed on the levers 104 and 105 whenever the shoji 102 is brought into the closed state. Upward protrusion 202
When the levers 104 and 105 pass each other, the inclined surface 401 engages with the upward protrusion 202 and rotates the levers 104 and 105 to a certain predetermined position. This rotation position is lever 10
4, the upward protrusion 202 formed at 105 is the protrusion 30
2, and in this state the lever 10
4 and 105 are set at the locking position.

The procedure for erecting a shoji screen equipped with a locking device according to this invention is as follows.

Lever 1 attached to the upper stile 103 of the shoji 102
04, 105 are pivoted toward the outside, for example. When in this position, lever 10
The upward protrusion 202 of No. 4,105 does not face the protrusion 302. In other words, in this position, levers 104 and 1
05 is set to the non-removal locking position. Therefore, the upper stile 103 of the shoji 102 can be pushed up deeply into the upper frame 301. Therefore, the lower stile can be built on the rail of the lower frame.

After installing the shoji 102 on the window frame 101, the shoji 1
02 to the closed window position and check whether the crescent can be locked. At this time, lever 1
04 and 105 each pass through the position of the downward protrusion 402. Therefore, the downward protrusion 402 is the lever 1.
04, 105 to rotate the levers 104, 105 toward the indoor side in this example. When levers 104 and 105 are set to this rotational position (the state shown in Figure 3), lever 1
The upward protrusions 202 of 04 and 105 face the protrusion 302, and the levers 104 and 105 are set at the locking position. In this state, the shoji 102 cannot be pushed up significantly. In this way, the locking state is automatically set.

The procedure for removing the shoji is as follows.

The pivoting free ends of the levers 104 and 105 attached to both ends of the upper stile 103 of the shoji 102 are visible on the door stop side of the vertical stile 102, so rotate the pivoting free ends toward the outdoor side with your fingers or the like. , set the levers 104 and 105 to the non-removal position.

When the levers 104 and 105 are set to the non-removable position, the upward protrusion 202 does not face the protrusion 302. Therefore, if the shoji 102 is pushed upward in this state, the shoji 102 can be lifted significantly upward and removed from the window frame 101.

<Effects of the invention> As mentioned above, according to this invention, no tools are required at all during installation and removal. However, once the shoji 102 is moved to the closed window position during construction, the upward protrusions 202 formed on the levers 104 and 105 will definitely engage with the downward protrusions 402 formed on the block 104, and this engagement will cause the lever 104 to close. , 105 are rotated so that they do not come off. Therefore, it is possible to obtain a highly reliable shoji door locking device that is always set to the locking state without any special setting operation.

In addition, with this invention, installation and removal can be performed at any position, and it is convenient to confirm that the locking state has been reached by looking at the positions of the free rotation ends of the levers 104 and 105.

In the above, an example in which this invention was applied to an outer shoji screen was explained, but it is easy to understand that it can also be applied to an inner shoji screen.
