Description

Forced locking device for left and right common door lock {FORCED LOCKING DEVICE OF A DOOR LOCK FOR COMMON USE OF LEFT AND RIGHT HANDED PERSON}

The present invention relates to a common left and right door lock, and more particularly to a forced lock of the common left and right door lock that can be used in common for the left and right door.

In general, the door is provided with a door lock for restricting unauthorized access of outsiders. As shown in FIG. 1, the door lock includes a housing 1 fixedly installed in the door D, a “protrusion position” A on the outside of the housing 1, and an “insertion position” B on the inside of the housing 1. Dead bolt (3) which is installed so as to move in and out, and movement means (5) for moving the dead bolt (3) between the "protrusion position" (A) and the "insertion position" (B), for example, driving With a motor.

In addition, the door lock is provided with a force locking device 7 for forcibly locking the dead bolt 3 in the “projection position” A. FIG. The forced locking device 7 is composed of a locker 7a installed in the housing 1 so as to fit into the locking groove 3a of the dead bolt 3 disposed in the “protrusion position” A. As shown in FIG. Here, the locker 7a fitted to the locking groove 3a restricts the motion of the dead bolt 3, thereby forcibly locking the dead bolt 3 disposed at the “projection position” A. FIG.

According to such a door lock, the exercise means 5 is operated by using a key button or a safety key from the outside of the door D. Then, the exercise means 5 moves the dead bolt 3 from the "protrusion position" (A) to the "insertion position" (B), or from the "insertion position" (B) to the "protrusion position" (A). It is to lock or unlock the door (D).

On the other hand, when forcibly fixing the door in the locked state, the locker 7a is manually raised from the inside of the door D. Then, the locker 7a is fitted into the locking groove 3a of the dead bolt 3 disposed at the “protrusion position” A while rising upward. As a result, the dead bolt 3 is limited in motion in the state where it is disposed at the “projection position” A, and thus the door D is forcibly fixed.

However, such a conventional door lock has the advantage of limiting the opening of the door (D) to limit the access of the outsider, according to the opening method of the door to be installed, the left hand-type door lock, excellent door lock, There are disadvantages to be produced in two ways.

That is, the door is divided into a left-handed door that is opened to the left centering on the hinge and a rainy-type door that opens to the right around the hinge. Therefore, there is a disadvantage that the door lock installed on the door must also be designed and manufactured in two ways corresponding to the opening method of the door.

Meanwhile, in consideration of this, recently, left and right common door locks that can be used in common for left and right doors have been developed. As an example, FIGS. 2A and 2B show a configuration showing a common left and right door lock and an example of its use. According to this, the left and right common door lock has a housing 10 fixedly installed in the door D, and the dead bolt assembly 20 is installed in the housing 10.

The dead bolt assembly 20 is installed to move left and right by moving between the “first position” (C) on the left side of the housing 10 and the “second position” (E) on the right side of the housing 10. And a first dead bolt 24 and a second dead bolt 26 fixed to both of the movement rods 22. In particular, the first dead bolt 24 and the second dead bolt 26, the moving rod 22 is moved between the "first position" (C) and "second position" (E) housing ( 10) to protrude to one side or the other, respectively. Here, the first dead bolt 24 and the second dead bolt 26 projecting to one side or the other side of the housing 10, respectively, the housing 10 is a left-sided door (LD) or storm water door (RD) In any case, it is configured to protrude from the doors LD and RD to lock the doors LD and RD.

And the left and right common door lock is provided with a drive motor 30 for moving the dead bolt assembly (20). The drive motor 30 moves the dead bolt assembly 20 from the "first position" (C) to the "second position" (E), or from the "second position" (E) to the "first position" (C). The first dead bolt 24 and the second dead bolt 26 provided at both ends thereof can be projected to one side or the other side of the housing 10, respectively.

And the left and right common door lock is provided with a force lock 40 for forcibly locking the dead bolt assembly 20 disposed in the "first position" (C) or "second position" (E). The force lock 40 has a first locker 42 fitted into the locking groove 20a of the dead bolt assembly 20 disposed at the “first position” C, and a “second position” E. FIG. The second locker 44 is fitted into the locking groove 20a of the dead bolt assembly 20.

According to the left and right common door lock of such a configuration, by configuring the dead bolt assembly 20 for locking the door so as to protrude to one or the other side of the housing 10, the left-right type regardless of the opening method of the door It can be used in both door and rain door.

However, such a conventional left and right common door lock, although there is an advantage that can be commonly used in both the left and right door, the forced lock device 40 for forcibly locking the dead bolt assembly 20 is Since it consists of two lockers 42 and 44, there are disadvantages that are difficult to manufacture and cumbersome to use.

That is, according to the conventional locking device 40, the dead bolt assembly 20 must be locked in the "first position" (C) or lock in the "second position" (E), depending on the manner of the door, Two lockers 42 and 44 are respectively installed to lock the dead bolt assembly 20 in the "first position" (C) or "second position" (E). Therefore, two lockers 42 and 44 need to be installed in the housing 10, and the housing 10 needs to be processed several times to install the two lockers 42 and 44. Therefore, many manufacturing processes and many parts are required. There are disadvantages.

In addition, since the two lockers 42 and 44 are installed in the housing 10, there is a somewhat confusing disadvantage in the process of the user operating it. That is, as shown in FIG. 2A, when the door lock is installed in the even type door RD, the first bolter 42 is operated to lock the dead bolt assembly 20, and as shown in FIG. 2B, the door lock is left-right. When installed in the door LD, the second locker 44 must be operated to lock the dead bolt assembly 20.

Therefore, the door lock user has to operate the first locker 42 and the second locker 44 separately according to the method of the door, and there is a risk of confusion during the operation. In particular, a novice user who is not familiar with the door lock often uses the first locker 42 and the second locker 44 confused, thus causing a problem of misoperating the door lock.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of which is to configure the dead bolt assembly can be locked in the first position or the second position with a single locker, The present invention provides a forced locking device for left and right common door locks that can be manufactured and assembled with a small number of labors, thereby improving productivity and workability and reducing manufacturing costs.

Another object of the present invention is to provide a forced locking device for the left and right common door lock, which is very easy to use by configuring the dead bolt assembly to be locked in the first position or the second position with one locker.
