JP6978648B2 - Strike for door lock - Google Patents

Description

The present invention relates to a strike for a door lock, and more particularly to a strike for a door lock that can be suitably used for an outset (external) sliding door.

Conventionally, outset (external) sliding doors that can be externally attached to the opening of a house have been known, and have the advantage that they can be installed more easily than sliding doors that are installed inside the opening. It is often used in remodeling and new houses.

By the way, as the outset sliding door, a lock having a type of locking piece that locks in the closing direction of the sliding door, which is widely used in sliding doors mounted inside the opening, cannot be used as it is.

Therefore, a sickle-shaped locking piece that appears in a direction orthogonal to the opening / closing direction of the sliding door (the surface side of the sliding door) (in the present specification, a lock having a sickle-shaped locking piece is referred to as a "sickle lock"). A sickle lock for an outset sliding door that is locked to a strike (seat) arranged on a pillar or the like has been proposed (see, for example, Patent Documents 1 and 2).

On the other hand, a general-purpose door lock strike is usually used for the strike (seat) corresponding to the sickle lock for the outset sliding door.
By the way, there are upper suspension type and lower load type outset sliding doors. In particular, the upper suspension type, specifically, the upper rail is attached to the upper part of the wall, and the sliding door is suspended along the wall surface. It is difficult to align the closing position of the sliding door, that is, the position where the locked piece appears and the opening position of the strike into which the locked piece is inserted. If the adjustment is performed, the relative positions of the two are likely to change significantly, and there is a problem that the alignment work requires a lot of work.

It should be noted that, for example, a strike in which the opening position of the strike into which the lock piece is inserted can be adjusted is also proposed (see, for example, Patent Document 3).
However, in the case of outset sliding doors, which generally do not have high installation accuracy, it is not enough to make the opening position of the strike into which the locking piece is inserted adjustable in one direction in order to achieve perfect alignment. A mechanism that can be adjusted in three directions: up and down, left and right, and front and back (the position where the tip of the sickle-shaped locking piece abuts and hangs) is compact so that it can be installed on the frame member on the fixed side, for example, the wall side. It is necessary to put it together.
