Closure base (16), and a latch interlocking lever (17) which is pivotally attached to the closure base (16) with a shaft (26) and connected to the latch (7) so as to rotate integrally with the latch (7). And a first close lever pivotally attached to the closure base (16) with a shaft (18a), and an arm portion (18b) connected to the eccentric long hole (15b) of the sector gear (15) via a pin (22). (18), a second close lever (19) pivotally attached to the closure base (16) with a shaft (19a), and a second close lever (19) rotatably connected to the second close lever (19) with a shaft (23). 3 Close lever (20) and pivot base (16) are pivotally attached to closure base (16). And a cancel lever (21) in which a pin (25) protruding from the side surface of the lower end portion of the lever (20) is slidably fitted.
As shown in FIG. 5, the shaft (26) is located on the same axis as the latch shaft (9), and the end surface of the shaft (26) is a recess (26a) into which the tip of the latch shaft (9) can be fitted. Is formed.
[0016]
The latch interlocking lever (17) has a latch connecting part (17c) provided with a hole part (17a) into which the pin (7a) of the latch (7) is fitted, and a step part (17b) formed on the outer periphery. doing. The third close lever (20) has a push portion (20a) that can be engaged and disengaged with the step portion (17b) of the latch interlocking lever (17) at the lower end. The cancel lever (21) has a contact portion (21b) that can contact the cancel portion (11c) of the second open lever (11) at the lower end, and the second open lever (11) is opened. The abutting portion (21b) abuts on the canceling portion (11c), and the pushing portion (20a) of the third close lever (20) is disengaged from the step portion (17b) of the latch interlocking lever (17). The link between the close lever (20) and the latch interlocking lever (17) can be cut off.
[0017]
As shown in FIG. 5, the tip of the shaft (19a) of the second close lever (19) is pierced through the connecting hole (5a) of the cover plate (5), and the hole of the latch interlocking lever (17). The pin (7a) of the latch (7) is fitted to (17a), and the recess (26a) of the shaft (26) of the latch interlocking lever (17) and the tip of the latch shaft (9) are fitted in a straight line. By combining, the closure mechanism (3) and the lock body (2) can be easily and accurately coupled.
Instead of caulking solid wear axis (19a) of the cover plate (5), when screwed, it can easily be detached closure mechanism (3) from the lock body (2).
[0018]
When the closure mechanism (3) and the lock body (2) are connected, the latch (7), pole (8), second open lever (11), latch interlocking lever (17), cancel lever (21 ) Is movably arranged along the side of the lock body (2), so that each lever can be placed in a small space, and the first open lever can be opened efficiently with the first open lever (11). (10) and the cancel lever (21).
[0019]
When the lock body (2) is not connected to the closure mechanism (3), the lock body (2) is used as it is as a normal door lock device without a closure function. When the closure mechanism (3) is connected, Used as a door lock device with a closure. When the lock body (2) is used as it is as a door lock device without a closure, the window hole (4b) and the protruding portion of the latch shaft (9) should be covered with an appropriate cover (not shown). .
[0020]
The operation of the closure mechanism (3) is as follows. The sliding door closes to the half latch position, the latch (7) rotates from the open position shown in FIG. 8 to the half latch position shown in FIG. 9, the detection switch (29) is activated, and the half latch signal is output. Then, the motor (13) is controlled to rotate in the forward direction, and the sector gear (14) is rotated in the operating direction from the standby position. The third close lever (20) is inserted into the long hole (21a) of the cancel lever (21) via the first close lever (18) and the second close lever (19) by the rotation of the sector gear (14). Guided and moved downward, the push part (20a) engages with the step part (17b) of the latch interlocking lever (17), and together with the latch interlocking lever (17), the latch (7) is viewed from the half latch position. It is turned to the full latch position shown in FIG. When the latch (7) is rotated to the full latch position and the pole (8) is engaged with the latch (7), a full latch signal is output by the detection switch (29), and the motor (13) is controlled to rotate in reverse. The gear (15) is moved back to the standby position, and each lever is moved back as shown in FIG.
[0021]
When the sector gear (15) contacts the stopper (12a), the stopper (12a) is deformed by a predetermined amount and the controller detects an increase in the load on the motor (13), the reverse rotation of the motor (13) is stopped, Then, the sector gear (15) is stopped after the motor (13) is rotated forward for a certain short time. As a result, the sector gear (15) can be stopped after the hitting sound is eased, and the durability of the stopper (12a) can be improved.
[0022]
While the sliding door is being closed from the half-latch position to the full-latch position by the motor (13), if the handle is opened and the second open lever (11) is rotated, the door is being closed. Even you can open the sliding door. That is, when the second open lever (11) is rotated, as shown in FIG. 12, the first open lever (10) is opened and the pole (8) is released from the latch (7). At the same time, the cancel lever (21) is rotated counterclockwise, and the pushing portion (20a) of the third close lever (20) is released from the step portion (17b) of the latch interlocking lever (17), The latch (7) can be freely rotated in the opening direction, and the sliding door can be opened.
[0023]
