Description

Lock for door of double door {Locker for door of double sliding window}

The present invention relates to a lock lock device for a US door, and more particularly, a twist lock portion of a pair of lock doors, which are used to lock a door of a US door that is opened by sliding two doors to one side using a lock. If a spring is installed and a permanent magnet is installed on the vertical bar where the locking piece of the lock is in contact with each other, and the lock is not locked, each locking piece is applied to the elastic force of the spring and the magnetic force of the permanent magnet. By keeping it in close contact with the vertical bar of the door, it is possible to prevent the occurrence of a safety accident due to the protruding of the locking piece, and to prevent the locking device from being damaged or damaged by being stuck or caught by the door frame or the vertical bar of the door. In addition, when the door is locked with a lock, the locks are vertical bars of different doors. Invented to prevent the fixing screws, etc. from being exposed so that the lock can be separated from the vertical bar of the door by using a tool such as a driver without opening the lock while the lock is locked and completely prevented from entering the room. It is.

In general, a locking device used to lock a door or a shutter includes a fastener 1 having a ring-shaped lock hook 11 as shown in FIG. 1 and fixedly installed to a door or a door frame; A locking piece 21 having a rectangular hook insertion hole 211 into which the hook is inserted in the longitudinal direction from one side is provided, and a fixing piece 22 fixed to a door frame or a door by being hinged to the locking piece on the other side. It is composed of the formed lock (2).

In the conventional lock locking device having such a configuration, the hook 11 is inserted into the hook insertion hole 211 of the locking piece 21, and then the lock hook is inserted into the hook 11 to fill the door. Have locked up.

However, such a configuration has a state in which a screw or the like used to secure the fixing piece of the lock to the door or the door frame is exposed to the outside, so an unspecified person can use a tool such as a screwdriver without opening the lock while the lock is locked. Therefore, the fixing piece of the lock can be easily separated from the door or the door frame and invaded into the room, which is vulnerable to crime prevention.

In addition, the lock piece and the lock piece of the lock are simply connected by a hinge, so that the lock piece itself can be freely rotated from the connecting piece in the usual case when the lock piece of the lock is coupled to the hook and the door is not locked by the lock. If there is a form that protrudes there is a risk that a person is hit by a safety accident may occur, as well as a problem such as the door frame or door is stuck or damaged or damaged by the lock.

Therefore, in recent years, a multi-refractive lock locking device has been developed as a solution to solve such a problem, and has been proposed as a Patent Publication No. 10-1002238, which has a configuration in which a lock hook is formed integrally bent and fixed to a door or a door frame. Being a fixture; One end of the locking piece having a rectangular hook insertion hole into which the lock hook is inserted is coupled to one side of the connecting piece having a square plate shape through a second hinge, and the bottom of the fixing piece is connected to the bottom of the connecting piece via a first hinge. It is coupled to the upper surface foldable mutually and the locking piece is fixed directly to the door or the door frame in the state in which the locking piece and the fixed piece has a phase angle of 90 degrees to each other with the connecting piece therebetween;

In addition, the upper end of the fixing piece integrally bent the elastic locking piece toward the front portion to rotate the connecting piece 180 degrees toward the fixing piece about the first hinge, the lower end of the connecting piece is elastic to the elastic locking piece of the fixing piece The locking piece is fixed to the restoring force of the return spring in a state in which the return spring is installed in a second hinge that is secured by a locking mechanism and the lock piece and the connecting piece are foldably connected to each other. It rotates 180 degrees around a hinge, and it is a structure which maintains the form which adheres to the back surface of a connection piece.

However, the multi-refractive lock lock device having such a configuration includes a fastener having a protruding form of the lock hook as an essential component, so it can be applied only to a general sliding door or a sliding door and shutter having one door itself. There is a problem in that the two doors cannot be used by being installed on the middle overlapping vertical bars of the door of the US door that is opened by sliding the door.

In addition, among the components of the multi-refractive lock lock device, the structure of the lock is very complicated and the production cost of the product is greatly increased, and the area occupied by the lock itself is wide, so it is installed on the side of the vertical bar of the US door having a narrow area. Not only can not be used, but also has a very difficult problem operability.
