Description

[Detailed explanation of the idea] This invention relates to a locking device for a shoji screen.

Conventionally, to prevent shoji from falling off when fitted into aluminum sash sliding or single-sliding windows, etc., after the shoji has been fitted, a block to prevent the shoji from falling off is screwed onto the inner surface of the upper frame of the fittings, etc. Either reduce the spacing, or make the retaining metal fittings attached to the upper end of the vertical stile of the shoji so that they can slide vertically protrude from the upper end of the upper stile of the shoji into the inside of the upper frame of the fittings frame after the shoji is fitted. The conventional method was to tighten the upper frame with screws and reduce the distance between the inner surface of the upper frame and the retainer.

However, in any of these cases, it is essential to set the external locking blocks and retaining metal fittings completely separately from the fitting operation of the shoji, but this setting operation is often difficult when actually fitting the shoji. Because of this, if the shoji derailed from the rails of the lower frame for some reason, the shoji would come off the fitting frame and fall, causing damage and other problems.

In order to eliminate the above-mentioned disadvantages, this invention aims to provide a shoji retaining device that can be automatically set by the lifting action when fitting the shoji into a fitting frame. purpose.

To explain an embodiment, the shoji slip-off prevention device 1 according to this invention is installed at both left and right ends of the upper stile 5 of the outer shoji 4, of the inner shoji 3 and the outer shoji 4 fitted in the fitting frame 2. One of each can be installed.

As shown in FIGS. 3 and 4, the retaining device 1 has a bottom plate 6a attached to both left and right ends by flanges 6b.

The attachment, which is formed by bending a rectangular metal plate into a concave shape so as to be located slightly below 6b, is attached to the member 6 with a locking piece 7 that is biased upward and a retaining member 8 that is biased toward the indoor side. is attached so that it can be locked.

The locking piece 7 is attached to the hole 7b provided in the boss portion 7a by a shaft 9 with a head fixed to one end of the bottom plate 6a of the member 6, and is attached by a spring wound around the shaft 9. 10, the boss portion 7a is attached such that the upper end surface 7C of the boss portion 7a protrudes slightly upward from the upper surface of the flange 6b of the member 6.

The upper end surface 7C of the boss portion 7a protrudes from the upper surface 7d of the locking piece 7, and the lower end surface 7e of the boss portion 7a is attached to the member 6.
is located below the lower surface of the flange 6b.

The retaining member 8 has an upwardly bent piece 8b formed at a certain length along the outdoor side of a wedge-shaped horizontal plate 8a extending toward the locking piece 7, and one end of the horizontal plate 8a. It is pivotally connected to a headed shaft 11 fixed near the other end of the bottom plate 6a.

One end of the spring 12 wound around the shaft 11 is fixed to the member 6, and the other end is attached to the horizontal plate 8 of the retaining member 8.
a, and urges the retaining member 8 toward the side wall 7f of the locking piece 7.

In order to prevent the retaining member 8 from moving in the vertical direction, a raised piece 6C is formed on the bottom plate 6a of the member 6, and a raised portion 6d of the member 6 on the retaining member 8 side is installed. A horizontal projecting piece 6e is provided.

The detachment prevention device 1 configured as described above is fitted into the opening 13 provided in the horizontal connecting member 5C that connects the indoor and outdoor side panels 5a and 5b of the upper stile 5 of the outer shoji 4. The horizontal connecting member 5 of the upper stile 5 is connected to the flanges 6b, 6b.
C by screws 14 and 14.

Since this invention has the above-mentioned configuration, the outer shoji 4 (see FIGS. 3 and 4) to which the retaining device 1 is attached is attached to the upper frame of the fitting frame 2 as shown in FIGS. 5 and 6. When suspended into the upper frame 2a, the upper end surface 7C of the locking piece boss portion 7a
Since the lower end surface 2C of the shoji guide flange 2b protruding downward within the interior is pressed downward against the biasing force of the spring 10, the retaining member 8 releases its engagement with the locking piece 7. The folded piece 8b is rotated counterclockwise by the biasing force of the spring 12, and the rotation is stopped at the position where the bent piece 8b contacts the shoji guide flange 2b.

Next, when the outer shoji 4 is moved downward to fit into the rail (not shown) of the lower frame 2d, the bent piece 8b of the retaining member 8 is released from contact with the flange 2b, so that the retaining member 8 is held horizontally. The plate material 8a is rotated until it contacts the inner surface of the side plate 5a on the indoor side of the upper stile 5.

In this state, the bent piece 8b of the retaining member 8
As shown in FIGS. 8 and 9, the outer shoji 4 is located diagonally between the side plates 5a and 5b of the upper stile 5, so the distance that the outer shoji 4 can move upward is limited to the distance that the outer shoji 4 can move up. It is narrowed to a distance l between the upper end and the lower end of the flange 2b.

Therefore, if the value of this interval l is set so that the outer shoji 4 will not come off due to derailment, the removal prevention device 1 will be automatically set by the hanging operation when fitting the outer shoji 4 into the fittings frame 2. can do.

In addition, when removing the outside shoji 4 that has been fitted once from the fitting frame 2, a hole 15 (usually closed with a cap 16) provided in the side plate 5a of the upper stile 5 facing the bent piece 8b of the retaining member 8 is provided. It's broken.

) and insert a screwdriver etc. into the side plate 5 to remove the retaining member 8.
When pushed toward the b side, the retaining member 8 is prevented from rotating by the locking piece 7 that is moved upward by the spring 10 and returns to its original state (see Figures 3 and 4), making it easy to remove. can.

Moreover, the locking piece 7 and the retaining member 8 are connected to the opening 1 of the upper stile 5.
The attachment protruding downward from 3 is attached to the bottom plate 6a of the member 6, so that when the shoji guide flange 2b comes into contact with the upper end surface 7C of the locking piece boss portion 7a, the locking piece 7 can be easily moved downward. Because of the structure, the retaining device 1 is attached to the outer shoji 4
There is almost no risk of being damaged by the flange 2b when it is suspended.
