Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fastening fitting for tightening and fixing an inner shoji of a horizontally rotating double sash to an outer shoji.

In conventional fasteners of this kind, the operating portion was provided on the front surface of the interior side of the shoji, and the operating lock piece was inserted into the shaft of the fastener to be operated.

For this reason, there is a drawback that the operating part of the fastener can be seen from the front.
Furthermore, in a double sash that rotates on the horizontal axis, the vertical stile of the outer shoji and the sash frame are connected by a rotating shaft at the middle part, and are rotatably attached to the upper stile of the inner or outer sash. If the inner shoji is not fixed to the outer shoji with fasteners, but the outer shoji is rotated around the rotation axis, and the lower part of the outer shoji is opened to the outside, the lower part of the inner shoji will pivot downward due to gravity. Then, the inner shoji becomes vertical and the inner shoji separates from the outer shoji.

Since the weight of the inner shoji acts on the upper frame material of the outer shoji, the outer shoji also rotates rapidly and opens, creating a great danger.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a horizontally rotating double sash fastener that eliminates the inconveniences associated with the prior art and eliminates the dangers described above.

Next, description will be given with reference to the drawings.

First, to give an overview of the conventional tightening device for double sashes, as shown in FIGS. 4 was provided on the front surface 5 of the indoor side a of the inner shoji screen, and an operating lock-like piece 7 that engaged with the shaft portion 6 of the fastener 4 protruded from the front surface 5.

8 is a sash frame, and the sash frame and the vertical stile 9 of the outer shoji are rotatably connected by a rotating shaft 11 at an intermediate portion 10;
In addition, the inner shoji 2 is carried by the upper frame material 12 of the outer shoji 3.

Therefore, when the lower part 13 of the outer shoji 3 is opened so as to be exposed to the outdoor side, there are the above-mentioned drawbacks.

In addition, 14 is the lower part of the inner shoji 2. Next, to explain the present invention, as shown in FIG. Placed on the indoor side and with inner shoji 2
There is a certain amount of space 17 between the side wall 16 and the sash frame 8.
is defined.

The feature of the present invention is that the tightening fitting 20 is a component of the tightening device.
is attached to the side wall 16 of the inner shoji 2, and the operating lock piece 21 is operated in the space 17.

Therefore, the width of the side wall 16 is such that the fastener 20 can be attached thereto, and the space 17 is wide enough to allow the lock piece 21 to be operated.

The fastener 20 has a hole 22 through which a lock-like piece 21 is inserted, and a shaft 23 rotatably provided at the back of the hole 22 .
A hook 24 is fixed to one end of the shaft 23.

A catch 25 with which the hook 24 can engage is installed on the indoor side surface 5 of the outer shoji 3.

As clearly shown in FIG. 6, the operating lock piece 21 has a concave portion 26 at one end, and an operating portion 27 on the opposite side, and has a right-angled shape as a whole. It is preferable to be there.

The lock-like piece 21 further has stepped portions on both sides in front of the concave portion 26 to form corner portions 28 and 29.
6 is larger than the width of the connecting portion 31 between that portion and the operating portion 27; j-measure 32.

Further, as shown in FIG. 5, a pair of recessed grooves 33, 34 are provided at opposite positions on the diameter of the hole 22 of the fastener 20, and each protrusion 35, 36 of the portal portion 26 It is inserted through there.

A pair of grooves 37 and 38 are formed in the shaft 23 and engage the protrusions 35 and 36 therein.

When the operating lock piece 21 is attached to the fastener 20, as shown in FIG.
engages the shaft 23 and each projection 35.3 of the concave portion 26
6 are engaged in grooves 37 or 38 provided in the shaft 23, respectively, so that the lock-like piece 21 can be moved approximately 90 degrees in either direction.
By rotating the hook 24 and the catch 25, the hook 24 and the catch 25 are engaged and disengaged.

It goes without saying that in order to fix the inner shoji 2 to the outer shoji 3, the hooks 24 and the receivers 25 must be engaged.

As shown in FIGS. 4 and 5, when the hook 24 is engaged with the catch 25, each protrusion 35° 3 of the lock piece 21
6 are aligned with the corresponding recessed grooves 33, 34, so that the locking piece 21 can be removed from the fastener 20, and by removing the locking piece 21 in this way, the collision with the western part described below is eliminated. , the outer shoji 3 can be rotated so that its lower part is exposed to the outside.

To remove the inner shoji 2 from the outer shoji 3, the hook is 24 gold and the receiver is 2 gold.
5, it is sufficient to rotate the lock-like piece 21 in the engaged state approximately 90 degrees in either direction from that position as shown in FIG. 4, and FIGS. This shows that the gold 24 has separated from the gold 25.

In such a detached state, each protrusion 35.3 of the lock piece 21
6 does not align with the concave grooves 33 and 34, so the corner 2
8.29 cannot pass through the hole 22, and the lock piece 21 cannot be removed from the fastener 20.

Note that the sash frame 8 has a convex portion 3 that protrudes toward the outer shoji 3.
9, and the gap 40 between the convex portion 39 and the side wall of the door shoji 3 is smaller than the amount 41 that protrudes from the side wall 16 of the inner shoji 2 when the lock piece 21 is attached to the fastener 20. .

Therefore, if an attempt is made to open the outer shoji 3 to the outside with the lock piece 21 attached to the fastener 20, the operating portion 27 of the lock piece 21 hits the three convex portions and cannot be rotated.

Therefore, in this tightening device, when the inner shoji 2 is not fixed to the outer shoji 3, the lock-shaped piece 21 cannot be removed from the tightening fitting 20, so the outer shoji 3 cannot be rotated toward the outdoors.

Therefore, according to the present invention, when the inner shoji is poured from the outer shoji, it is prevented from opening the double sash outer shoji to the outside, so that the inner shoji is moved from the vertical shoji as in the past. No more separation and the dangers associated with it.

Seventh, there is an advantage that the fasteners and the operating lock-like pieces do not appear on the inside front of the interior shoji screen, so there is no need to make any improvements to the appearance.
