Abstract

PROBLEM TO BE SOLVED: To easily unlock a lock manually even in a fault or the like of a motorized lock by forming a stop wall where the front end of a lock lever firmly fixed to the output shaft of the motorized lock is engaged or disengaged, in the middle of a slider and interlocking the input shaft of a thumb-turn equipped on the backface side of the lock case with the output shaft of the motorized lock. SOLUTION: A lock lever 8 is firmly fixed to the output shaft 28 of a motorized lock 2 and a stop wall 29 where the front end of the lock lever 8 is engaged or disengaged is formed in the middle of a slider 19. The input shaft of a thumb-turn equipped at the backface side of a lock case is interlocked with the output shaft 28 of the motorized lock 2 through a gear structure. Accordingly, when the motorized lock 2 becomes unworkable owing to a fault in the electric circuit or the like of the motorized lock 2 or a power failure, in a locked state that the dead bolt 4 is engaged with a receive hardware at a fixed frame body side and a lock lever 8 is engaged with the stop wall 29 of the slider 19, the lock lever 8 can be separated from the stop wall 29 and the lock can be released by manually turning the thumb-turn to a specified direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clemon lock device used for a door of a communication device storage shelter or the like, and more particularly to a clemon lock device provided with a motor lock on the back side of the door.

[0002]

2. Description of the Related Art A problem arises when a motor lock is attached to the back side of a door of a clemon lock device and an operating handle of the clemon lock device or an interlocking mechanism between the operating handle and the deadbolt is restrained by a locking signal from an administrator. This is because when the motor lock becomes inoperable due to a failure of the electric circuit or components of the motor lock or a power failure, the door cannot be unlocked from the rear side, and workers etc. It is to be trapped.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a motor lock-equipped clemon lock device which can be quickly unlocked by a simple manual operation from the inside even when a motor lock fails or a power failure occurs.

[0004]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. In a clemon lock device with a motor lock according to the present invention, a main body case 1 fixed to a door 14 is provided.
The lock case 3 of the motor lock 2 is fixed to the rear side portion 1A of the
The operation handle 7 is attached to the front side portion 1B of the main body case 1, and the dead bolt 4 that engages with and disengages from the metal receiving portion 16 of the fixed frame 15 is disposed on the side surface of the main body case 1.
The drive hub 18 is fixed to the handle shaft 17 of the
The upper and lower sliders 19 and 20 are connected to the left and right arm portions 18a and 18b of the drive hub 18 by shaft pins 21 and 22, and the upper and lower lock bars 5 and 6 are connected to the sliders 19 and 20. The base end of the dead bolt 7 is connected to the shaft pin 23 by the
Are returned and urged by the springs 26 and 27. The lock lever 8 is fixed to the output shaft 28 of the motor lock 2 and the slider 19
A stop wall 29 is formed in the middle of the lock lever 8 so that the tip of the lock lever 8 can be engaged and disengaged. The thumb turn 11 is mounted on the rear side of the lock case 3, and the input shaft 30 of the thumb turn 11 is connected to the motor lock via a gear mechanism 31. 2 in conjunction with the output shaft 28.

As shown in FIG. 1, when the dead bolt 4 is engaged with the metal receiving portion 16 on the fixed frame 15, the upper and lower sliders 19, 20 have the lock bars 5, 6 with the main body case. Latches (not shown) connected to the lock rods 5 and 6 are also engaged with separate metal receiving portions on the fixed frame 15 side, and a so-called three-point lock is established. doing. When the door 14 is locked with respect to the fixed frame 15 in this manner, the worker or the manager supplies electricity to the electric circuit of the motor 10 of the motor lock 2 and increases the appropriate gear mechanism 13 in order to increase the security state. Output shaft 2 via
The slider 8 is driven to rotate, and the end of the lock lever 8 abuts against the stop wall 29 of the slider 19. As a result, the downward movement of the slider 19 is prevented, so that it is impossible to rotate the operation handle 7 from the front side of the door 14.

When a worker enters the inside of the shelter for checking the equipment or connecting the cable, the worker or the manager supplies an electric circuit for driving the motor 10 to rotate in the reverse direction, and rotates the output shaft 28 in the reverse direction. Then, the lock lever 8 is released from the stop wall portion 29. As a result, the movement constraint of the slider 19 is unlocked, so that the operation handle 7
The three-point lock described above is released by turning the door 14 by a required angle in a predetermined direction, and the door 14 can be opened.

[0007]

In the illustrated embodiment, the slider 19 is vertically guided by a guide pin 36 and a vertically elongated slot 37 fixed to the main body case 1. The lock bar 5 is connected to the pin 24 at the upper end of the slider 19. Pin 24 is the guide slot 3 of main body case 1
8 is inserted. The shaft pin 21 is inserted into a horizontally elongated slot 40 at the lower end of the slider 19. Shaft pin 22
Is inserted into a horizontally long slot 41 at the upper end of the slider 20, and the connecting pin 25 of the lock bar 6 is inserted into a guide slot 39 of the main body case 1. The dead bolt 4 is inserted into the through hole 43 of the main body case 1,
Are guided in the left-right direction by the horizontally elongated slot 42 of FIG. The slider return biasing springs 26 and 27 are formed of torsion coil springs.

The interlocking cylinder 32 is fitted and connected to the front end of the output shaft 28 of the motor lock 2, and the rotor 44 of the cylinder lock unit 12 with the lid 46 is fitted and connected to the front end of the interlocking cylinder 32. ing. Therefore, when the motor lock 2 breaks down or a power failure occurs, a predetermined key is inserted into the key hole 45 of the rotor 44 from the front side of the door 14 and the rotor 44
By turning in a predetermined direction, the lock lever 8 can be released from the stop wall portion 29 of the slider 19.

The motor lock 2 has two micro switches 3
The switch operation cam plate 9 is fixed to the rear end of the output shaft 28. When the actuator lever is pressed by the cam plate 9, the micro switches 33 and 34 detect a locked state or an unlocked state and output the detected state to a notification means such as a buzzer or a lamp.

[0010]

As described above, in the clemon lock device with a motor lock according to the present invention, the lock lever 8 is fixed to the output shaft 28 of the motor lock 2, and the tip of the lock lever 8 is engaged with the middle part of the slider 19. The lock case 3 is provided with a stop wall 29 to be detached, the thumb turn 11 is mounted on the rear side of the lock case 3, and the input shaft 30 of the thumb turn 11 is connected to the motor lock 2
, The dead bolt 4 is engaged with the metal receiving portion 16 of the fixed frame 15, and the lock lever 8 is engaged with the stop wall portion 29 of the slider 19. In the above, when the motor lock 2 becomes inoperable due to a failure of an electric circuit or a component of the motor lock 2 or a power failure, the worker inside the shelter receives a thumb turn 11.
Can be manually rotated in a predetermined direction to release the lock lever 8 from the stop wall portion 29, and unlock the door 1
4 can be opened from the inside.
