Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener for pulling a window shoji to close it.

[0002]

2. Description of the Related Art As shown in FIG. 6, a fastening device for a window shoji has a body (2) attached to a window frame (1) and a receiver (4) attached to an openable / closable window shovel (3). ing. The main body (2) is provided with a lock pin (6) which moves up and down by the operation of the lever (5), and the receiving tool (4) has an insertion opening (7) for receiving the lock pin (6). A receiving groove (8) extending vertically is provided following the insertion opening (7). When opening the window shoji, use the lever
6 (B) is moved to the position indicated by the alternate long and short dash line in FIG. 6 (B), the lock pin (6) is positioned at the insertion opening (7) of the receiving member (4), and the window shoji is moved in the direction of arrow (9). . Further, when closing, as shown in FIG. 6 (C), when the window screen is closed and the lock pin (6) is inserted into the insertion opening (7) of the receiving tool (4), the lever (5) is closed. The lock pin (6) is operated to move inwardly of the receiving groove (8), and the window shoji is pulled up.
Close as in (A).

In this way, the window shoji can be closed, but a bar is inserted into the gap between the window frame (1) and the window shoji (3) from the outside.
If you insert the lever (10) etc. and pry it open with a strong force, the gap between the window frame and the window shoji will widen and the lock pin (6) will rest on the receiver (4).
There is a possibility that the window screen (3) may be opened by slipping out of the receiving groove (8) and being disengaged from the receiving tool (4). Further, at this time, in order to forcefully open the window shoji, the receiving groove (8) of the receiving member (4) is deformed to widen the space, or the slider (11) protruding from the lock pin (6) is removed. It is deformed and the lock pin is even easier to slip out of the receiving groove (8).

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a tightening metal fitting as described above, in which the lock pin and the receiving member are prevented from being disengaged from each other even when the window shoji is forcibly opened. is there.

[0005]

According to the present invention, a lever is provided.

Further, there is provided the above-mentioned tightening metal fitting, wherein both sides of the receiving groove of the receiving member are surrounded by side walls of a reinforcing plate, and the base portion of the lock pin is held by a guard plate having a guide groove.

[0006]

1 and 2 show an embodiment of the main body of the fastener of the present invention, in which a lever (1) pivotally attached to the main body (15) is shown.
A crank (18) is attached to the pivot shaft (17) of 6), and the tip of the crank (18) is in sliding contact with the leaf spring (19). A slider (21) slidably fitted to a guide strip (20) provided on the main body (15) is formed, and between the legs (22), (22) formed inside the slider (21). A crank pin (23) provided on the crank (18) is fitted in the crankshaft. A lock pin (24) is provided on the outer side of the slider (21).

With the above structure, when the lever (16) is rotated, the lock pin (24) is moved up and down through the slider (21) as shown in FIGS. 2 (A) and 2 (B). Move. At the tip of the lock pin (24), a receiving member (2
A flange (27) wider than the width of the receiving groove (26) of 5) is provided.

A guide groove (2) through which the lock pin (24) is inserted is provided on the front surface of the slider (21) having the lock pin (24) provided in a protruding manner.
A guard plate (29) having 8) is provided (Fig. 3). An enlarged hole (30) into which the flange (27) of the lock pin (24) can be inserted, at the end of the guide groove (28) of the guard plate.
Are formed. The end is an end on the side where the lock pin (24) is located when the window shoji is opened,
Thereby, the guard plate (29) can be attached to the main body (15) afterwards or can be removed if desired. The main body (15) and the guard plate (29) have mounting holes.
Screws are inserted through (31) and (32) to attach to the window frame (33).

FIG. 4 shows an embodiment of the receiver (25), which is a lock pin (24) having the flange (27).
Following the insertion opening (34) and the insertion opening (34) capable of receiving the, in the figure, the receiving groove (26) extending in the vertical direction,
Lock pin (24) from the insertion slot (34) to the receiving groove (26)
An inclined surface (35) is formed so as to draw in. Side plates (37) and (37) are provided on both sides of the surface plate (36) forming the receiving groove (26).
The side plates (37), (37) to surround the side walls (38), (38) to form a substantially U-shaped reinforcing plate (39), the side walls (38), (3)
8) and the side plates (37), (37) are welded together. In addition, the above-mentioned receiving member is press-molded with a stainless material or the like,
The shape shown in FIG. 4 may be integrally formed by die casting or the like. The receiver (25) is attached to the window screen (41) by inserting a screw into the attachment hole (40).

When the main body (15) is attached to the window frame (33) and the receiving member (25) is attached to the window shoji (41), the window shoji (41)
When the lock pin (24) is closed, the lock pin (24) moves into the receiving slot (34) of the receiver (25), and the lever (16) is operated to move the lock pin (24) to the receiving groove (26). Then pull the window shoji (41) (Fig. 5). At this time, the flange (27) is
Located inside (26).

In the closed state as shown in FIG. 5, a ball or the like is inserted into the gap (42) between the window frame (33) and the window shoji (41) to close the window shoji.
When the (41) is forcibly opened, the flange (27) wider than the width of the receiving groove (26) provided at the tip of the lock pin (24) engaged with the receiving groove (26) is received. Since it hits the inner edge of the groove (26),
The lock pin (24) does not come out of the receiving groove (26),
The gap (42) can be prevented from expanding.

Further, since both sides of the receiving groove (26) of the receiving member (25) are surrounded by the reinforcing plates (39), the width of the receiving groove (26) is large even if a large force is applied to the receiving groove. Can be prevented from expanding.
When the guard plate (29) is provided on the front surface of the slider (21), the flange (27) of the lock pin (24) comes into contact with the inner edge of the receiving groove (26) so that the lock pin is closed by the window sliding door. It is possible to prevent the slider from being deformed even if it is pulled in the
It is possible to further prevent the (24) from coming out of the receiving groove (26) of the receiving tool (25).

In the above embodiment, the main body (15) is provided on the window frame (33) and the receiver (25) is attached to the window screen (41) side, but the receiver (25) is attached to the window frame (33) side. 25) may be provided, and the main body (15) may be attached to the window shoji (41) side. Further, although the main body is attached to the vertical frame so as to operate the lever (16) in the vertical direction, the main body may be attached to the horizontal frame to operate the lever in the horizontal direction.

[0014]

The present invention is constructed as described above, and in the tightening metal fitting, a flange is provided at the tip of the lock pin operated by the lever of the main body, and when the window shoji is closed, the lock pin receives the receiver. Since the flange is located inside the receiving groove, the locking pin does not come out of the receiving groove even if you try to open the window shoji by force, and both sides of the receiving groove are safe. Of the receiving groove can be prevented from expanding by surrounding it with a reinforcing plate, and a guard plate can be provided on the front surface of the slider having the lock pin projecting to prevent the slider from being deformed to prevent the lock pin from being deformed. It is possible to prevent it from coming off the receiving tool further, and to enhance the crime prevention effect.
