Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door for which appearance is important, such as a door of a store or a front door of a house, and a cylinder lock for locking the door is placed at any place other than the door. The present invention relates to a remote control box lock that can be provided in.

[Conventional technology]

In a box lock that locks and unlocks a door, a cam plate that rotates by a thumb-turn operation from inside the room and a cylinder lock operation from the outside causes a dead bolt to appear and disappear.

To open the unlocked door, turn the door handle (lever handle or knob) and immerse the latch bolt.

Since both the dead bolt and the latch bolt are provided in the box lock installed inside the door, a cylinder lock having a key insertion port is located near the door handle on the surface of the door.

Doors that need to be locked, such as store doors and entrance doors of houses, are also easily noticeable, and because of the design of the door that makes the appearance of the door beautiful, the surface of the door has a conspicuous cylinder lock. It is better not to have.

However, in order to lock and unlock the door from the outside, it was not possible to remove the cylinder lock from the outside surface of the door.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a remote control box lock that can be operated by a cylinder lock provided on a wall of a door frame.

[Means for Solving the Problems]

In order to achieve the above object, in the remote control box lock of the present invention, the rotation amount of the cylinder lock provided at an arbitrary position of the frame wall is transmitted to the cam plate of the box lock through the inside of the strike box. The two driven pieces, which are inserted in the front of the box lock so as to be able to move forward and backward, are pivotally attached to the two opposite positions of the cam plate via the connecting pieces, respectively, and are internally provided at the end of the frame. At the both ends of the arm pivotally attached to the middle of the strike box, two pushers, which can be retracted from the strike box toward the above-mentioned two driven pieces, are pivotally attached, and provided on the frame wall. A lever is fixed to the rotor of the cylinder lock and one end of the wire is fixed to the tip of the lever, and the other end of the wire is fixed to the arm.

[Action]

When the key is inserted into the cylinder lock of the remote control box lock configured as described above and rotated in the locking or unlocking direction, the lever of the cylinder lock rotor rotates and the arm rotates via the wire. Then, one of the two pushers pivotally attached to both ends of the arm moves forward to push the pushed piece in the box lock, and the pushed push piece moves through the connecting piece. A rotational force is transmitted to the cam plate, the cam plate rotates in the locking or unlocking direction, and the door is locked or unlocked.
