Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a catch device for a latch lock that is installed on a gate and can be remotely controlled electrically.

[Conventional technology]

Conventionally, this type of seat device operates an electric drive member so that the receiving portion is reversed or moved either up or down when energized (for example, Japanese Patent Publication No. 34634/1989).

[Problem that the invention attempts to solve]

The structure of such a receiving part has the disadvantage that it has a large number of parts, which may cause failure, and since it is visible from the outside, it can be destroyed by unauthorized means.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has a handle that is rotatably provided, a rotating rod that rotates when the handle is operated, and a recess that protrudes from the cutout that opens at the tip of the rotating rod. A latch that is biased in the direction, and a cylinder lock that prevents the rotation of the rotation rod by a locking mechanism. a recess into which the tip of the latch is inserted, a protrusion that protrudes into the latch entry port of the recess and engages with the latch, and a plunger that is provided so as to be retractable toward the recess and that protrudes in response to an unlock signal and pushes the latch. The present invention provides a catch member having an electromagnetic solenoid.

[Effect]

When the gate is closed, the latch that has hit the projection retracts and overcomes the projection, is inserted into the recess, and then projects again and engages with the projection. When the latch lock is locked, the pivot rod cannot rotate, so the gate cannot be opened. However, when an unlock signal is sent to the catch member from the outside, the plunger of the electromagnetic solenoid protrudes and locks the latch. Because it moves,
The engagement between the latch and the protrusion is released and the gate can be opened.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the present invention, in which A represents a seat member and B represents an external perspective view of a latch lock.

This seat member A forms a recess 2 into which the latch 1 fits when the gate is closed, and a protrusion 3 at the entrance of the latch 1. An electromagnetic solenoid 4 is buried in the lower part of the seat member A, and the head 5a of a plunger 5, which is provided in the electromagnetic solenoid 4 and advances when energized, faces into the recess 2.
The plunger 5 of such an electromagnetic solenoid 4 is always urged by a spring 10 and buried in the electromagnetic solenoid 4, but moves forward when energized (for example, a JUM type solenoid manufactured by Hoshi Electric Manufacturing Co., Ltd.).

In addition, a recessed cutout 7a is formed at the tip of a rotating rod 7 provided in the latch B and rotated by the handle 6, and the latch 1 and a spring 8 for biasing the latch 1 are housed in the recessed cutout 7a. do.

The latch 1 accommodated in the pivot rod 7 in this way is
When locked, the latch 1 is fitted into the recess 2 of the seat member A, and the flat portion 1a of the latch 1 is in contact with the protrusion 3 of the seat member A.

Conventionally, when the cylinder lock 9 is unlocked with a key (not shown), the handle 6 can be rotated freely, and the latch 1 can be released by rotating the rotation rod 7. To release the latch 1 from a remote location when the handle 6 cannot be rotated due to Projection 3
The engagement with is released at the same time. The door can be opened in this state.

[Effect of idea]

As described above, in the present invention, an electromagnetic solenoid is buried in the lower part of the catch member, and the plunger of this electromagnetic solenoid is located in the lower part of the latch, so that when the electromagnetic solenoid is energized, the latch is pushed up by this plunger. The release operation can be performed from the ground, the head of the plunger inside the catch member is only slightly exposed to the outside, and the catch member that engages with the latch and the protrusion are integrally formed. This has the effect that there is no captivity that can be destroyed, and damage can be prevented.

Claims (1)

[Scope of utility model registration request] A handle that is rotatably provided, a rotating rod that rotates when the handle is operated, a latch that is biased in a direction protruding from a recessed cutout that opens at the tip of the rotating rod, and A recess into which the tip of the rotary rod is inserted when the door is closed, and a recess into which the tip of the rotary rod is inserted when the door is closed, relative to the position of the latch lock provided on the gate when the gate is closed. The invention is characterized in that it is provided with a catch member having a protrusion that engages with the protrusion latch, and an electromagnetic solenoid having a plunger that is provided so as to be able to protrude and retract toward the recess and that protrudes and pushes the latch in response to an unlocking signal. A catch device for latch locks.
