Problems solved by technology

That is, the doorknob needs to be grasped and turned to push open, while the user may be nervous enough to grab the handle, and it may be difficult for children to grasp the doorknob and turn
[0006] In addition, when a conventional general ferrule (a ferrule that simply protrudes and pulls in a latchbolt pin) is applied to a sliding door, excessive load and frictional load will Acting on the flat surface of the latchbolt that abuts against the striker of the door requires excessive force to draw the latchbolt, so the user needs to apply excessive force to open the door

Abstract

The invention relates to a latch bolt rotation type for door lock mortise, and more particularly relates to the latch bolt rotation type for door lock mortise with the following features: at combination of a trough, formed in a latch pin, of the latch pin and a round-shaped pin portion of a rotational basis member, a latch pin is fixed or unfixed and is capable of rotating when the round-shaped pin portion of a rotation allowing unit enters or divorces from the trough of the latch pin.

Description

technical field [0001] The present invention relates to a latch rotation type for door lockmortise, and more particularly, to a latch rotation type for door lockmortise characterized in that: a latchbolt groove formed in a latchbolt The circular pin part of the rotation reference part is combined with the circular pin part of the rotation reference part. As the circular pin part of the rotation allowing part enters or disengages from the latchbolt groove part, the latchbolt is fixed or released to be able to rotate. Background technique [0002] Generally, a door lock mortise includes a latchbolt protruding and drawing in toward a side of a door by a rotating unit of a lever or the like. The latchbolt is the unit used to prevent the door from being opened automatically (ie, only perform the function of closing), not the locking unit. Therefore, recently, a dead bolt that is locked and unlocked by a knob or a grip is provided, and a dead bolt that realizes a locking structur...
