Description

[Detailed Description of the Invention] This invention relates to a shoji fall prevention device, and particularly aims to provide a shoji fall prevention device with a structure in which the fall prevention device operates reliably when the shoji is erected.

<Background of the invention> In general, window devices can be freely removed from the window frame, but if this is the case, there is a risk that the device may accidentally come off the window frame when opening or closing. It is especially dangerous if a shoji shoji accidentally falls outside on the second or higher floors. For this reason, in order to prevent the shoji from being removed from the window frame once it has been erected, a device for preventing the shoji from falling is attached to the shoji.

<Prior art> Conventional shoji fall prevention devices include, for example, a resin block attached to the upper end of the stile of the shoji so that it can slide freely in the vertical direction, and the resin block is moved upward while the shoji is built into the window frame. Generally used is a structure in which the shoji is secured with screws in the same state and the resin block prevents the shoji from being lifted upwards.

<Conventional Disadvantages> As described above, since the work of screwing the resin block is required during the construction work, if this screwing work is done, the shoji will be left in a state where it can be freely removed, which is dangerous.

<Purpose of the invention> This invention provides a shoji fall prevention device that automatically sets the shoji fall prevention device to an operating state without any special setting work for the fall prevention mechanism during construction work. This is what I am trying to do.

<Embodiment of the invention> An embodiment of the invention is shown in FIGS. 1 to 4. In the figure, 1 indicates the upper frame of the window frame, and 2 indicates the vertical frame of the window frame. 3 indicates the upper stile of the outer shoji, and 4 indicates the vertical stile of the outer shoji.

In this invention, at least the upper stile 3 of the outer shoji is provided with a sliding plate 5. This slide plate 5 is the fourth
As shown in the figure, both sides engage with grooves 6a and 6b formed in the upper stile 3, and the upper stile 3 is supported so as to be freely slidable in the longitudinal direction.

A cam 7 is rotatably attached to the slide plate 5. The cam 7 has a substantially rod-like shape, and one end of the rod-shaped cam 7 is rotatably attached to the slide plate 5. The rod-shaped cam 7 has a long hole 7a along the longitudinal direction.
A pin 8 embedded in the upper stile 3 is inserted into the long hole 7a.
engage. Although only one bar-shaped cam 7 is shown in the figure, it is actually attached to both ends of the upper stile 3, so that a total of two bar-shaped cams 7 are provided. Further, the rod-shaped cam 7 is made of, for example, stainless steel.

An adjustment mechanism 9 is provided on one end side of the slide plate 5, that is, on the side of the doorstop surface 4a of the shoji, and the abutment piece 11 is guided out through this adjustment mechanism 9. The adjustment mechanism 9 includes a member 9a bent in a direction perpendicular to the extending direction of the slide plate 5, a member 9b bent in a direction perpendicular to the extending direction of the abutment piece 11, and these members 9a and 9.
It can be configured by a bolt 12 passed between b. The bolt 12 is threadedly engaged with one member, for example 9a, and loosely engaged with member 9b. With such a structure, by adjusting the rotation of the bolt 12, the member 9a is threaded and connected to the abutment piece 11 and the slide plate 5.
The length between the ends can be adjusted. A hole 4b is formed in the vertical stile 4, and the bolt 12 can be rotated through the hole 4b by a screwdriver, so that the length between the abutment piece 12 and the slide plate 5 can be freely adjusted.

The abutment piece 11 protrudes from the doorstop surface 4a during construction. A claw 13 is formed on the back side of this protruding abutment piece 11.

<Operation of the invention> When installing the shoji in the above-described structure, the abutting pieces 11 are guided out so as to protrude toward the doorstop side of the shoji. This extraction is carried out by lifting the abutting piece 11 upward to lift the claw 13 above the wall 4c of the stile 4, and in this state, the abutting piece 11 is led out to the outside. That is, at this time, the members 9a and 9b are bent, and the abutment piece 11 is lifted upward, allowing the abutment piece 11 to be pulled out.

When the abutment piece 11 is led out, the cam 7 is connected to the pin 8.
Since the cam 7 moves in the direction away from the elongated hole 7a
When engaged with pin 8, it falls down, and its upward height becomes lower. Therefore, the shoji can be erected with the cam 7 lying down.

When the shoji is opened/closed in the erected state, the abutting pieces 11 abut against the vertical frame 2, and the abutting pieces 11
is pushed and pushed into the inside of the upper stile 3 of the shoji. At this time, the slide plate 5 moves to move the cam 7 toward the pin 8, and the cam 7 rises due to engagement between the pin 8 and the elongated hole 7a.

Therefore, when the abutment piece 11 is pushed into the upper frame 3, the cam 7 rises and is in the state shown in FIG. When the cam 7 is up, the gap between the upper end of the cam 7 and the lower surface of the upper frame 1 becomes smaller, and the amount by which the shoji can move upward when the shoji is lifted is limited by the amount formed between the lower stile and the lower frame of the shoji. This is the amount that will prevent it from disengaging from the rail. Therefore, when the cam 7 is in the upright position, the shoji cannot be removed from the window frame.

On the other hand, when the abutment piece 11 is pushed toward the upper stile 3, the claw 13 climbs over the wall 4c of the stile 4 and moves to the opposite side. In this state, even if one attempts to simply pull out the abutment piece 11, the claw 13 abuts against the wall 4c, and the abutment piece 1
1 cannot be extracted easily. In addition, abutting piece 1
1, it is necessary to lift the abutment piece 11 upward while pulling it out. Therefore, it is impossible to pull out the abutment piece 11 and release the operating state of the fall prevention device by mischief.

<Effects of the invention> As explained above, according to this invention, the fall prevention device is set to the operating state by opening and closing the shoji in the erected state and abutting the abutting pieces 11 against the vertical frame 2. can do. Therefore, it is possible to provide a highly reliable fall prevention device that can be reliably set in the operating state without causing any wrinkling of the fall prevention device.

In addition, since the adjustment mechanism 9 is provided between the abutment piece 11 and the slide plate 5, the cam 7
If the upper end is already in contact with the upper frame 1, adjust the rotation of the bolt 12 of the adjustment mechanism 9 to shorten the length between the abutment piece 11 and the slide plate 5, and the cam 7 It can be adjusted to a slightly inclined state as shown in FIG. 3 when it is at its highest point. Therefore, even if there is some variation in the gap between the upper frame and the shoji, it can be adjusted to the optimum state by the adjustment mechanism 9.
