DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door lock device which can be attached to fittings of various thicknesses, and which can increase the range of fitting thickness of the fitting.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
In a, connecting legs c and c are projected from the back surface so as to face each other across the lock body b, and an interlocking bar (square core) e linked to the hub d of the lock body b is connected to the connecting legs c and c. Those engaged with c are commercially available.

[0003]

In the above prior art, the connecting legs of the puller are opposed to each other with the thick lock body interposed therebetween, so that the connecting legs cannot be made longer, and the thickness of the fitting can be increased. There is a problem that the range cannot be increased.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a lock device in which tabs are provided on both sides of a fitting in which a lock body is embedded. The plate is made to protrude out of the lock box, and the operation plate is provided with a linking part and is formed thinner than the lock box.
A connecting leg is projected from the back surface so as to face each other with the operation plate interposed therebetween, and an interlocking bar linked to the linking portion is engaged with the connecting leg.

[0005]

[Function] Since the connecting legs of the tab are opposed to each other across the thin operating plate, the connecting bar can be extended to engage the interlocking bar in a wide range, and the range of the mountable fitting thickness can be increased. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A lock body 1 comprises a lock box 4 and a lock piece 5 and an operation plate 6 in a lock box 4.
Are rotatably supported by a rotation shaft 9 and a rotation shaft 10, respectively. The lock piece 5 can be protruded and retracted from the front of the lock box 4, and a part of the operation plate 6 is always The connecting portion 7 is provided at the protruding portion. The lock piece 5 and the operation plate 6 are linked by a distribution spring 8, so that a locked state and an unlocked state are distributed. A centering hole 23 is provided in the lower rear part of the lock body 1. The lock piece 5 and the operation plate 6 may be integrated.

[0007] The handle 2 is disposed on the indoor side and has a handle portion 2.
A lock piece 11 is provided in the inside of the lock piece 11 so as to be vertically movable, and a cylindrical connecting leg 13 is provided on the upper back surface of the lock piece 11 so as to protrude inward.

The handle 3 is arranged outside the room, and the handle 2
A handle 21 is provided so as to face 0, and a display window 19 is provided above the handle 21. The emergency unlocking piece 12 is provided in the display window 19 so as to be movable up and down, and a cylindrical connecting leg 14 is provided on the back surface thereof so as to face the connecting leg 13, and the front surface is provided at the center. An emergency operation unit 22 having a short cylindrical shape is provided, and the upper part of the emergency operation unit 22 serves as a red lock display unit 15. In addition, two centering legs 17, 17 and 18, 18 are provided in parallel on the upper and lower portions of the upper half of the handle 3, respectively. Note that the centering legs are provided in parallel in order to be able to cope with pulling the fitting right or left.

To attach to the fitting T, first, the lock body 1
Is embedded in the large surface of the fitting T, and the handle 3 is
The lower centering leg 18 is inserted into the centering hole 23 of the lock body 1 and the upper centering leg 17 is connected to the lock body 1.
It is arranged so that it contacts the upper surface of. Next, the interlocking bar 16 is moved through the link 7 of the operation plate 6 of the lock body 1 to pull the handle 3.
And the tab 2 is arranged from the indoor side surface such that the interlocking bar 16 is inserted into the connection leg 13. Finally, the tabs 2 and 3 are connected by the mounting screws 24 and 25, and the fittings T are sandwiched therebetween.

The locking operation will be described. At the time of unlocking, the locking piece 11 is in the upper position, and the emergency operation part 22 is on the display window 19 (the state of FIG. 4). When the locking piece 11 is lowered from this state, the locking piece 11 is inserted into the connecting leg 13. Interlocking bar 1
6 depresses the linking portion 7 to rotate the operation plate 6, and the lock pieces 5 engaged with the rotation also rotate and protrude from the lock box 4 and are locked by receiving members (not shown) (FIG. 5). (A) state. At this time, the emergency unlocking piece 12 is also pushed down by the interlocking bar 16, the emergency operating section 22 is lowered, and the red lock display section 15 is exposed from the display window 19 (the state of FIG. 3A).

Next, the unlocking operation will be described. When the locking piece 11 is raised from the above state (the state of FIG. 3A), the interlocking bar 16 fitted to the connecting leg 13 is
Is pushed up to rotate the operation plate 6, and the lock pieces 5 engaged with the operation plate 6 are also rotated and accommodated in the lock box 4 and unlocked (the state of FIG. 5B). At this time, the emergency unlocking piece 12 is also
6, the emergency operation unit 22 is lowered, and the red lock display unit 15 is not exposed from the display window 19 (the state of FIG. 4). Note that the same operation is performed even when the emergency operation unit 22 is raised from the outdoor side.

The thickness of the fitting T to which the lock device of the present invention can be attached is changed from the state in which the connecting legs 13 and 14 are in contact with both surfaces of the operation plate 6 (the state shown in FIG. 3 (B) of FIG. 3 (the state shown in FIG. 3B).

[0013]

As described above, according to the present invention, since the connecting legs of the puller are opposed to each other with the thin operating plate interposed therebetween, the connecting legs can be extended to engage the interlocking bar in a wide range. This has the effect that it can be attached to a wide range of fittings from small to large in thickness.
