Description

Locking apparatus of glass door

The present invention relates to a lock for a glass door, and to reduce the inflow of air from the outside to maintain an appropriate room temperature, and also to a glass door lock that is not easy to cut to prevent theft.

In general, the locking device of the glass door is composed of an indoor locking member equipped with a locking lever in each of the inside and the outside of the “??” shaped fixing plate fitted from one side of the door, and an outdoor locking member equipped with a key cylinder.

At this time, the lock rod, which is inundated by the operation of the key cylinder and the lock lever, hangs on the insertion groove of the door frame, is formed only on the indoor lock member, and the key cylinder and the lock lever are interlocked so that only the indoor lock member is operated by these operations. Locking rod is mounted on the insertion groove of the door frame, the locking can be made.

An example of a conventional glass door locking device having such an operation structure is described in detail in Utility Model Registration No. 20-327466 (hereinafter referred to as "registration room").

As shown in FIG. 1, the door locking device in the registration room includes a support piece 10 fitted to both sides from one side of the glass door 1; In the state of being mounted on both sides of the support piece 10, each of the locking rods 22 and 39 are raised by the locking lever 21 and the key cylinder 32, and the insertion groove 2a formed in the door frame 2 is provided. (2b) consists of the interior, the outer locking member 20, 30 to be inserted into.

In more detail, each of the lock lever 21 of the indoor locking member 20 and the key cylinder 32 of the outdoor locking member 30 which are fastened and fixed to both sides of the glass door 1 are operated. A door lock device for allowing the locking rods (22) and (39) to stand out individually to perform the locking and unlocking of the door, comprising: a key cylinder (32) fixed to the through hole of the outdoor case (31); A fixed body 33 penetrating the key cylinder to be stably fixed; A catching jaw (34) for holding the outer surface of the fixture on the inner surface of the case; A rotation cam 35 which is fitted to the rotation shaft 35a of the key cylinder; A moving body 36 moving left and right according to the rotation angle of the rotation cam; It provides a structure characterized in that the locking rods 39 formed with the locking groove (39a) is fitted to each other so that the locking piece (38) formed in the engaging piece 38 formed on one side of the movable body.

However, the conventional glass door locking device having the structure as described above is composed of the interior, the outer locking member is integrally formed, the gap generated when the lock member and the wall is in close contact with the bar, the interior air through such a gap Can be leaked to the outside or the air in the room can be flowed into the room, reducing the airtightness between the interior and the exterior, and in summer or winter, it is a negative factor in controlling the temperature of the room, causing waste of cooling and heating energy. It is.

In addition, the lock bar is horizontally arranged in the conventional glass door locking device, bar insertion can be easily inserted through the gap bar can easily cut the lock bar has a very low anti-theft effect.

The present invention has been devised to solve the conventional problems as described above, by forming one or more grooves in each of the locks, which are coupled and fixed to both ends of the glass door, thereby reducing the gap caused by mutual overlap of the locks from the outside. The object is to provide a glass door lock with reduced ventilation flow.

In addition, another object of the present invention is to provide a glass door locking device to increase the anti-theft effect by forming a cutting prevention projections at the corresponding ends between them so that insertion of the cutting tool in the locked state is not easy.
