Description

[Detailed description of the invention] This invention relates to a shoji door locking device used for sliding shoji (including anti-sliding shoji).

Generally, in soundproof sashes, a door locking device is used to draw the outer shoji next to the inner shoji and seal it, and various door locking devices have been devised so far.

This invention is related to the improvement of the above-mentioned door locking device, and when the vertical frame of the shoji to which the door locking fittings are attached is distorted or curved, or the shoji is not completely closed, the door locking fittings may not be able to catch the locking device. To provide a door locking device for a shoji shoji, which can securely lock the metal fitting even when the metal fitting is not at a predetermined locking position, and also facilitates the handle operation of the door locking fitting.

Hereinafter, embodiments of this invention will be described in detail based on the accompanying drawings.

Reference numeral 1 is a movable shoji, and 2 is a sliding shoji.

A door locking fitting 3 and a receiving fitting 4 are fixed to predetermined positions on the end faces of the vertical frames 1a and 2a of both pupils.

The door clamp 3 has a handle 5 that is rotatable in the inside and outside directions of the shoji.
An arm 6 that is coaxial with the handle 5 and rotates with the handle, and an arm head 7 provided at the tip of the arm.

The bracket 4 consists of a mounting seat 8, and a mounting protrusion 9 that stands upright from the mounting seat 8.

In the mounting, the seat 8 has an inclined surface 10 inclined in the direction of rotation of the arm 6, and the protrusion 9 of the receiver has an inclined surface 11 inclined in a direction perpendicular to the direction of rotation of the arm 6.

When the door clamp 3 and the bracket 4 are in the correct position, turn the handle 5 of the door clamp 3 in the direction of the arrow to move the arm head 7, and the bracket of the bracket 4 to the inner surface of the protrusion 9. The door is closed by engaging the movable shoji 1 and drawing the movable shoji 1 so as to seal the gap S' between the movable shoji 1 and the fitted shoji 2.

Further, when the vertical stile 1a of the movable shoji 1 is curved as shown by the chain line, the door locking fitting 3 engages with the receiving fitting 4 through the following process.

When the handle 5 is rotated, the end surface 7a of the arm head 7 comes into contact with the inclined surface 10 of the mounting seat 8.

When the handle 5 is continued to be rotated, the end surface 7a becomes the inclined surface 1.
0 and moves a distance a.

In other words, the curved vertical stile 1a is brought closer to its normal position by a distance a.

At the same time, the arm 6 also moves by a distance a' and its corner 6a hits the inclined surface 11 of the protrusion a.

When the handle 5 continues to be rotated, the corner 6 of the arm 6
A slides on the inclined surface 11 and moves by a distance, and the vertical stile 1a reaches its normal position.

(At this time, the end surface 7a of the arm head 7 is separated from the inclined surface 10 by a distance b'.

) and when the handle 5 is further rotated, the arm head 7
The support engages with the inner surface of the protrusion 9.

In particular, at the tip of the arm head 7, as shown in FIG.
It is rotatably mounted.

In addition, the inclined surfaces 10 and 11 formed on the seat 8 and the protrusion 9 for mounting the bracket 4 will reliably pull the shoji even if the door clamp is misaligned due to distortion or curvature of the vertical stile. The angle of inclination is set so that it can be locked by tilting it.

In FIG. 6, reference numeral 12 is glass fitted into the shoji, and 13 is a tight material that seals the gap in the sliding shoji.

As described above, according to this invention, when the handle of the door locking bracket is operated, the arm head, which rotates as the handle rotates, slides on the inclined surface of the seat and the arm is attached. While the corner part is sliding on the slope of the protrusion,
To reliably lock an arm head to a metal fitting while returning a misaligned or distorted stile of a shoji to its normal position.
