Description

{Locking Device for Hinged Door}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door lock device, and more particularly, to a lock device installed in a hinged door furniture provided with a pair of left and right doors while being used in a home or an office.

In the home or office, a variety of furniture is used to store various documents and articles. Most of these furniture are made of a structure in which a door is opened and closed by a hinge (hereinafter referred to as a "hinged door").

In the above-described hinged door furniture, a locking device is provided, as required, such that the locking device is configured such that the locking device is protruded or inserted inside the locking device by the rotational movement of the key.

The furniture body is provided with a hole through which the locking device protruding from the locking device can be inserted or a separate fixing device.

With such a structure, when the user inserts the key into the keyhole of the locking device and then rotates at a predetermined angle, the locker protrudes from the inside of the locking device and is inserted into the hole or fixture formed in the body of the furniture, It is fixed to the body and the door is locked.

In this case, in the case of a double-door type hinged door having a pair of left and right door openings, a separate latching piece is provided to prevent the other door from being restrained by the door provided with the locking device so that when one door is locked, So that both doors are not opened.

However, the double-door hinged door furniture having the above structure is merely configured not to be opened by the door that is simply fixed by the fastening piece, so that when the large external force acts, the fastening piece is deformed or broken and the door can be opened easily.

In order to prevent this, a door is fixed by attaching a separate latch which is manually operated inside the door where the locking device is not installed. In this case, the user has to open the door by locking the door .

Therefore, in recent years, a locking device capable of firmly fixing both doors in a double door type door furniture has been developed.

The lock mechanism disclosed in this patent document includes a key that is rotatably received and coupled, and a key formed on a part of the first door, A first lock member including a key bundle portion that is received in and coupled to the bundle receiving hole and a latch piece which is extended or retracted in the first direction by rotation of the key to engage or disengage from a part of the inner surface of the second door, A rotary member coupled to the inner surface of the door so as to be rotatable about an axis and adapted to receive linear motion of the engagement member extended or contracted in the first direction and to convert the linear motion into rotary motion, And is accommodated or received in the engaging piece accommodating portion formed on at least one side of the furniture body The sum consists of the second locking member including a fitting piece to be released.

However, the locking device disclosed in the above patent document requires a separate mold for the first locking member, the rotating member, and the second locking member, so that it takes a lot of manufacturing cost, Therefore, it is necessary to use a separate auxiliary tool to precisely adjust the position of each of the components to be installed and then install the lock device. Therefore, it takes much time to install the lock device.

Accordingly, it is required to develop an improved locking device which can easily and firmly lock a pair of left and right doors using a single locking device in a locking device installed in a double door type sliding door furniture.

6, the keypad 40 includes a key block 41, which is rotatably installed in the accommodation space 11 of the housing 10 and in which a keyhole is inserted, The first and second lockers 30A and 30B are protruded from the outer surface of the block 41 so as to be in contact with the first and second lockers 30A and 30B, And second cam blocks 42A and 42B for sliding the first and second cams 30A and 30B.

The key block 41 is formed in a cylindrical shape and protrudes to one side of the housing 10 and has a key hole (not shown) penetrating the inside thereof. A key hole is formed in the key block 41 A plurality of structures selectively pressed by grooves and projections formed in the inserted key are provided. Since the structure of the key block 41 is well known and widely used, a detailed description thereof will be omitted.

1 and 2, the key block 41 is provided with a closing ring 43, which is formed in a ring shape and is detachably attached to the key block 41. As shown in FIG. When the locking device 1 is installed on the rear side of the door and the keyhole of the key block 41 is exposed to the front side of the door through a hole formed in the door, Is installed on the front side of the door so as to cover the gap between the blocks (41).

The first and second cam blocks 42A and 42B are curved portions 42A 'and 42B for sliding the first and second lockers 30A and 30B while being in contact with the first and second lockers 30A and 30B, And 42B 'supporting the first and second lockers 30A and 30B which are slidably connected to the curved surfaces 42A' and 42B '.

When the user inserts the key into the keyhole of the key block 41 and rotates the keyhole 40 at a predetermined angle according to the structure of the keyhole 40 as described above, The first and second rockers 30A and 30B which are in contact with the first and second cam blocks 42A and 42B while the first and second cam blocks 42A and 42B are rotated are provided on the curved surfaces 42A 'and 42B ') And the planar portions 42A' 'and 42B' ', respectively.

In the above description, the locker body 31 of the first and second lockers 30A and 30B is provided so as to protrude outside the housing 10 by a predetermined length. Alternatively, the first and second lockers 30A, And 30B may be accommodated in the housing 10 and protrude outside the housing 10 during the locking operation.

The door lock device of the present invention constructed as described above is installed in a casement door furniture provided with a pair of right and left doors. Hereinafter, the lock device 1 according to the present invention will be described in detail. Will be described according to an installed embodiment.

≪ Example 1 >

Embodiment 1 is an example in which the lock device 1 is installed in the single-layer cabin 2 and the cabin 2 is provided with the first and second lockers 30A Grooves or fasteners 3 and 4 are respectively provided on the left door 2A at the positions corresponding to the first and second door frames 30A and 30B and the upper inner surface 2 '

The fasteners 3 and 4 have a structure in which an insertion groove A having a predetermined size is formed as shown in FIG. 9. The fasteners 3 and 4 are formed by a left door 2A and a cabinet 2, Is inserted into a groove formed in advance on the inner side 2 'of the cabinet 2 and then is firmly fixed with screws to the inner side 2' of the cabinet 2 and the left door 2A.

10, when the lock 40 is rotated at a predetermined angle by inserting the key into the keyhole with the left and right doors 2A, 2B being closed, The first and second lockers 30A and 30B are slid and protruded by the first and second cam blocks 42A and 42B so that the left door 2A and the fasteners 3 and 4 provided on the inner surface 2 ' The front ends of the first and second lockers 30A and 30B are inserted into the first and second lockers 30A and 30B so that the left and right doors 2A and 2B are simultaneously locked by the first and second lockers 30A and 30B .

When releasing the lock of the door, the user inserts the key again into the keyhole, and then rotates the catch 40 in the direction opposite to the direction in which the door is locked. Thus, the first and second cam blocks 42A and 42B The first and second lockers 30A and 30B are unlocked and thereby the first and second lockers 30A and 30B are locked by the elastic restoring force of the elastic spring 33 provided to the first and second lockers 30A and 30B, The front ends of the first and second lockers 30A and 30B inserted into the fasteners 3 and 4 are released while the left and right doors 2A and 2B are simultaneously unlocked.
