Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an on / off mechanism of a sliding door switch for turning on / off a switch provided in a lock box of a sliding door lock (single sliding door, sliding door).
[0002]
[Prior art]
A sliding door lock for a joinery provided with a trigger (horizontal advance / retract member) that protrudes from the front of the lock box toward the metal fitting and a locking piece (for example, sickle piece) linked to the trigger is disclosed in, for example, Japanese Utility Model Publication No. 57-110260. It is described in the publication.
[0003]
With this type of sliding door lock, when the sliding door is closed, the trigger begins to retract when the tip of the trigger comes into contact with the strike surface, and the sickle piece projects in the direction of engagement through a power conversion mechanism (for example, rack and pinion). To do.
[0004]
By the way, since the sliding door returns due to the “bounce phenomenon of the sliding door (bounce back)” when the sliding door is suddenly closed, generally, the so-called “ "Chile (gap)" is set. This dust is provided, for example, about 0.5 mm to 5 mm.
[0005]
In addition, the rebound phenomenon has a considerable impact on the members that make up the lock-unlocking / unlocking mechanism, so we have devised to move the sickle piece back slightly toward the lock box in response to the rebound of the sliding door. (For example, patent application 2001-125739).
[0006]
The sliding door switch on / off mechanism is no exception, and depending on the configuration of the switch installation location and the switch holding mechanism for the movable contact piece of the switch, the sliding door rebound phenomenon is likely to occur. In particular, in the case of a mechanism that picks up the locking signal when the door is closed or closed by using the movement of the trigger, the trigger moves to the strike side via the power conversion mechanism or the like by the amount of rotation of the sickle piece due to the collision. Because of the advancing relationship, it is required to reliably and stably obtain a closing signal or a locking signal when the door is closed, even if the above-described chisel size of about 0.5 mm to 5 mm changes.
[0007]
Japanese Patent Laid-Open No. 3-12128 is disclosed as a prior art disclosure obligation. The switch of the energizing device described in this publication does not include the switch in the lock box. However, the switch has a “movable contact body” and is provided on either the upper part of the sliding door or the door frame. To pick up.
[0008]
[Problems to be solved by the invention]
An object of the present invention is that a locking signal or a closing signal at the time of closing can be reliably and stably obtained even when the chile size changes corresponding to the rebound generated when the sliding door is suddenly closed. . In particular, in the present invention, even if the control body is further pushed in, or even if the control body corresponds to the dust size, the close relationship between the movable contact piece of the switch and the control body does not change much.
[0009]
[Means for Solving the Problems]
