Description

[Detailed Description of the Invention] The present invention relates to a latching device for a sliding door in furniture, in which a latch is released by pressing a latch actuator provided in an opening of a pulling handle in the opening direction, and the sliding door can be opened as it is. It was done like this.

Next, the details will be described with reference to the illustrated embodiment.
In the figure, (1) is the main body of furniture such as a storage cabinet, (2),
(2 ') is a sliding door juxtaposed so as to be flush with the doorway of the main body (1), (3) is a pulling door opening of each sliding door (2), (2'), and is shown for the left sliding door (2). In FIG. 2 and subsequent figures, (4) is a latch actuator, and a seat plate (7) having a substantially concave cross section is fixed to a cover plate (6) provided on the back surface of the front plate (5) of the door body (A). The latch actuator (4) is slidably fitted in the guide groove (7 ') at the center of the seat plate (7) in the left-right direction, and is elastically urged by the return springs (8), (8). The outer working edge (4 ') faces the inner edge of the pull tab opening (3). In the figure, (9) is a stopper of the latch operator (4) provided on the pull tab opening member.

(10) and (10) are approximately L provided above and below the latch actuator (4).
It is a character-shaped rotating plate, and is composed of upper and lower convex portions (7a), (7
(a) is pivotally attached (10 '), and its longitudinal arm (10a) is fitted in the groove (4a) provided in the latch actuator (4), and the long hole (10a' provided in the arm (10a). ) Is a pin fixed to the latch actuator (4)
It is fitted in (11) so that it can slide and rotate freely.

On the other hand, a bearing plate (12) is attached to the lower outer edge of the cover plate (6).
A latch shaft (13) is rotatably supported through (12 '), and a latch (14) is fixed to the latch shaft (13). The latch (14) is a door body (A).
It is fitted to the engaging hole (15) that is projected laterally from the body (1) and is bored in the inner side plate portion of the doorway, and is resilient to the return spring (16) mounted between the body (A) and the door body (A). The hook (14a) at the tip is engaged
It is locked to the hole edge of (15). Latch shaft (13) is latch (14)
Are restrained by the upper plate part (12a) of the bearing plate (12), and the latch shaft (13)
Since the lower end portion of the cover plate is pressed against the inner surface of the lower plate portion of the cover plate (6), the movement in the vertical direction, that is, the axial direction is prevented. In the figure, (17) is a back plate of the door body (A).

Thus, one end of the connecting plate (18) is pivotally attached to the tip (10b ') of the slightly descending lateral arm (10b) of the rotating plate (10) below the latch actuator (4), The other end (18a) of the connecting plate (18) is connected to the lateral arm (10a).
At the position above the tip (10b ') of b), the lateral arm (10
An operating arm formed by bending the upper part of the latch shaft (13) at a substantially right angle so that b) and the connecting plate (18) have a substantially V shape.
It is pivotally attached to (13a).

Since this sliding door latch device has the above-described structure, the operating edge (4 ') of the latch actuator (4) is pushed against the return spring (8) by the fingers inserted into the pull opening (3) in the door opening direction. When pressed, the rotating plate (10) connected to this with the pin (11) rotates, and the lateral arm (10b) of the lower rotating plate (10) rotates upward and the connecting plate (18). Since the actuating arm (13a) of the latch shaft (13) is pivoted outward via the lever, the latch (14) also pivots against the return spring (16) and the hook (14a) engages. Since it is disengaged from the hole (15), the sliding door (2) can be opened in a sliding manner in front of the other sliding door (2 ') by the pull opening (3).

When the sliding door (2) is closed, the inclined portion of the hook (14a) engages with the hole edge of the engagement hole (15) and rotates against the return spring (16) to move the engagement hole (15). After passing through, the hook (14a) is returned to the return spring (16).
By doing so, it returns to its original position and automatically engages with the hole edge.

(19) is a cylinder lock provided on the front plate (5) of the sliding door (2),
By locking the lock (19), the key plate (19a) is rotated from the vertical position to the horizontal position, and the lower extension plate portion (10) of the lower rotation plate (10) is rotated.
It can be locked because it engages with c) and prevents the rotation plate (10) from rotating. Although the left sliding door (2) has been described above, the latch device for the right sliding door (2 ') has a structure similar to that of the left sliding door (2) and is made symmetrical.

As described above, the sliding door latch device of the present invention pushes the operating edge (4 ') of the latch actuator (4) in the door opening direction with the fingers inserted into the pull opening (3) as described above. Since the latch shaft can be unlocked by rotating the latch shaft (13) via the connecting plate (18) and the operating arm (13a), the latch lock can be unlocked and the door opened. In addition, the pressing force of the return spring for pressing the latch (14) is increased in order to securely lock the latch to the hole edge of the engagement hole (15) in the closed state. Therefore, when opening the door,
Although the latch (14) must be rotated in the unlocking direction with a strong force against the pressing force of the return spring, in the present invention, as described above, the lateral arm (of the rotating plate (10) ( 10
b) and the connecting plate (18) are connected in a dogleg shape, and when the latch actuator (4) is pressed, the latch shaft (13) is connected to the lateral arm (10b) of the rotating plate (10) and the connecting plate (10). Since it is designed to rotate strongly by the toggle action of 18), the latch (1
4) is a practical effect in that it can be pivoted in the unlocking direction easily against the return spring to perform the door opening operation very easily, and has a simple structure and is extremely easy to manufacture. have.
