Description

Door lock with adjustable length {omitted}

The present invention relates to a lock of a door of adjustable length, and in detail, a locking device for sliding doors in which two doors are in close contact with each other. It is possible to prevent theft and safety accidents caused by outsiders intrusion, and to prevent the child from falling out of the door lock.

In general, sliding doors are used to allow two doors to be in close contact with each other and to be opened in one direction.

The sliding doors are installed in the form of two or more doors in close contact with each other so that they can be installed in a doorway occupying a large space such as a living room door of an apartment or a house. The door is equipped.

In the use of the same sliding door, the living room door is often opened to some extent for indoor ventilation, there is a problem that the door can not be locked when the door is open to either side.

The above problem becomes a necessary factor to close the door as if a person goes out, and if it does not, it sees an open living room door and recognizes that the outsider door is not locked. .

Therefore, in the case of the sliding door as described above, the user is always in the room, there is a need to repeat the operation of opening and closing the door if necessary.

According to the present invention, a sliding door does not allow an outsider to intrude even when a user opens a part of a door by necessity and maintains a locked state even if the user does not close the open door.

The present invention is a means for solving the above problems, the first body formed with a locking jaw and the guide groove and the first inner portion, and the second inner portion and the guide groove is formed by coupling to the first inner portion The locking device comprises a second body for coupling the locking bolt to the bolt ball of the locking jaw and the fixing jaw, and a third body for coupling the locking bolt to the one or more spacing bolts, by coupling to the second inner portion of the locking jaw and the fixed ball. To provide.

According to the present invention, even when the user opens the door for indoor ventilation, the door can remain locked, and the door remains locked even when the door is open or out of the open state, so the door remains open. There is an effect of achieving stability while achieving this.

The present invention has the effect that the lock is not recognized from the outside while acting as a security window without the grate, and performs an auxiliary lock function to lock the door, can be used as a substitute when the existing lock is broken, by the use of the lock Due to this can suppress the opening of the door, there is an effect of preventing the fall of children that occur when children open the door arbitrarily.

The configuration of the present invention is as follows.

The first body 10 having the locking jaw 11, the guide groove 12, and the first indentation part 13 and the first indentation part 13 are coupled to each other to form the second indentation part 21. And a guide groove 22, a second body 20 for coupling the locking bolt 26 to the bolt hole 25 of the locking jaw 23 and the fixing jaw 24, and the second indentation. By coupling to the portion 21, it is composed of a third body 30 coupled to the locking bolt 32 to one or more spacing bolt ball 31.

As described above in detail the locking device 40 by combining the first body 10, the second body 20 and the third body 30 as follows.

Locking device 40 of the present invention, the second body 20 is coupled to the first inner portion 13 of the first body 10, the second inner portion 31 of the second body 20 It is to combine the third body (30).

When the body 10, 20, 30 is coupled as described above, the fixing jaw 24 of the second body 20 via the locking bolt 26 via the guide groove 12 of the first body 10. The third body 30 inserted into and fixed to the bolt hole 25 formed in the second hole 20, and the guide groove 12 and the first body 10 of the second body 20. The locking device 32 is configured by inserting the locking bolt 32 into the gap adjusting bolt hole 31 of the third body 30 in the state via the guide groove 12.

In the locking device 40 configured as described above, the third body 30 and the locking bolt 32 are guided by the guide grooves 12 and 22 of the first body 10 and the second body 20. The gap is adjusted while the locking bolts 26 and 32 move, and the locking bolts 26 of the second body 20 are guided and moved to guide grooves 12 of the first body 10. The length of the lock 40 is to be extended.

Looking at the combined use of the locking device 40 and the door (1) (2) extending in length by sliding the body 10, 20, 30 as described above is as follows.

In a state in which the space C between the door 1 and the locking device 40 is secured by protruding the locking device 40 as shown in FIG. 4 attached to the door frame 3 fixing the doors 1 and 2, The fixing screw 4 is inserted into the screw through hole 40-1 of the locking device 40 to engage with the door frame 3.

When the locking device 40 is fixed to the door frame 3 as described above, the door 2 is locked to the door frame 3 or another door of the sliding door, so that the door 1 is opened and locked when the door 1 is opened. Since the door 40 is opened by the device 40 as much as the space C and is no longer open, the door 1 and 2 remain open for the range specified by the user, so that the user 1) It is to maintain the safety by securing the locked state of the door (1) (2) while achieving the purpose of opening (2).

The locking device 40 of the present invention protrudes only the third body 30 from the first body 10 or the third body 30 together with the size of the doors 1 and 2 to be installed. 2 protrudes the body 20, so that the length of the locking device 40 can be extended, and by selectively fixing the locking bolt 32 coupled to the third body 30 to the space adjusting bolt ball 31 , It is possible to adjust the interval of the third body 30 protruding from the first body (10).

In the present invention, when the second body 20 protrudes from the first body 10, the inclined catching jaw 11 and the inclined catching jaw 23 of the second body 20 formed in the first body 10. This engagement is to prevent the second body 20 from falling out of the first body (10).
