Description

Mortise lock assembly case for door

The present invention relates to a mortise-integrated case for a door, and more specifically, a mortis lock is a door lock with a deadbolt having high stability, meaning that it is mainly used for a front door, but generally using a lever together with a deadbolt. It relates to a case for a mortis lock for a door to be integrally formed including a ratchet part having a ratchet bolt for easy opening and closing.

Mortise lock is a door lock with dead bolt with high stability, meaning that it is mainly used for front doors, but generally refers to an opening and closing device including a ratchet bolt so that it can be opened and closed easily using a lever along with a dead bolt. .

In relation to the technology of the Mortis Lock, Republic of Korea Patent No. 1455783 (announced on November 4, 2014) states that 'a body including a front plate with a first protrusion hole, a first guide part, a first installation part and a first shaft tongue part, a housing having a cover coupled to the body and a receiving portion surrounded by the body and the cover; It has a ratchet passing in and out of the first protruding hole of the housing body, a first guide bar connected to the ratchet and arranged in the receiving part of the body, and a first insertion hole into which the first guide bar is fitted, and the first installation part of the body The coupled locking piece, the first coil spring extrapolated to the first guide bar and arranged between the ratchet and the locking piece to help the ratchet always in and out, and the second insertion hole guided along the first guide part of the body and into which the first guide bar is fitted and a ratchet bolt including a first guider arranged at the rear of the locking piece; a first lever having a fastening end connected to the first guide bar of the ratchet bolt, a first swing shaft coupled to the first shaft tongue of the body of the housing, and a first shaft hole formed in the first swing shaft; a handle including a shaft coupled to the shaft hole of the first lever and a grip coupled to the shaft shaft; A stop end having a tool coupling portion is provided at the rear end of the first guide bar of the ratchet bolt, and a second coil spring having greater elasticity than the first coil spring is provided between the first guider and the stop end. It is extrapolated to the first guide bar, and an access hole is formed on the opposite side of the first protrusion hole in the body, so that the second coil spring is contracted by the pressure of the tool inserted through the access hole in the tool coupling part of the stop end of the first guide bar. As the first guide bar and the ratchet protrude, the direction is changed by rotating the ratchet out of the area of the first protruding hole, and the front plate of the body further includes a second protruding hole, and the second protruding hole is formed. In and out of the dead bolt; consists of including.

As described above, in the mortis lock, the ratchet part and the deadlock part are integrally formed and used integrally for window doors, system doors, doors, fire doors, etc., or the ratchet part and the deadlock part are used separately. Since the opening/closing direction of the door is different, when it is installed incorrectly, it has to be detached and re-installed again, or it is difficult to assemble because it is cumbersome to install it after loosening and recombining the parts and setting the position when assembling.

In addition, when assembling the deadlock part and the ratchet part, the inside is made of an iron plate material, and the front part uses a separate stainless steel lace material that does not rust. There were problems with damage.

In addition, the conventional mortis lock case shown in FIG. 5 is formed in a structure in which the front plate part 610 and the body part 620 are separated, and is fixed by welding a separate 'C'-shaped bracket 590 when combined. Since the cover plate 630 is fixed and fastened with a fixing piece afterward, there are problems of an increase in the manufacturing cost due to welding and a change in the material of the welding part, and a separate fastening bracket 660 is used to fix the key bundle part. There was a problem in that the production process to be installed was increased in cost.
