Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a strike of a sliding door lock. More specifically, the present invention relates to an improvement in strike in which a hook protruding from a main frame of a sliding door lock is engaged and disengaged.
[0002]
[Prior art]
The hook of the sliding door lock that is attached to the sliding door door or the sliding door summoning section and the strike that the hook selectively engages with each other will loosen when engaged unless the proper relative position is taken. Will occur and the sliding door will rattle. In extreme cases, engagement is even difficult.
[0003]
Several conventional adjustable strikes have been proposed to properly adjust or readjust the relative position between the hook and the strike when the sliding door lock is installed or after prolonged use. However, each has drawbacks to be solved.
[0004]
In the strike disclosed in Japanese Utility Model Publication No. 58-46194 or Japanese Utility Model Publication No. 61-173665, the engaging member pivotally supported by the strike frame can be oscillated and displaced by a screw adjusting means composed of a male screw and a female screw. However, it is easy to change the engagement member due to the swing of the mounting member (door frame or sliding door) during use, and the engaging member can be easily changed. It has problems such as complexity.
[0005]
In the strike disclosed in Japanese Utility Model Publication No. 58-143947, the engaging member pivotally supported by the strike frame is oscillated and displaced by the sliding means of the slide plate via a linkage means comprising a pair of a pin and a long hole. Although it was made possible, it has a drawback that the structure is too complicated for the function.
[0006]
Furthermore, the strike disclosed in Japanese Utility Model Publication No. 3-30529 is formed by axially supporting an engaging member having a locking portion with respect to a strike frame (fixed frame) in the front-rear direction, and moving the above-mentioned axial support point up and down. It is formed so that it can move in the direction, and the rotation shaft is pivotally supported at a position different from the pivot point of the engaging member, and both ends of the rotation shaft can be moved to the inclined elongated holes formed in the strike frame. A screw hole perpendicular to the axis is formed in the rotation shaft, and an operation screw for moving the rotation shaft is screwed into the screw hole.
[0007]
The strike according to this device has been improved so that the vertical position of the locking portion does not fluctuate greatly even when the engagement member is moved in and out, thereby increasing the flexibility of attachment and ensuring the engagement of the hook. However, when the mounting member (door frame or sliding door) swings during use, the screw adjusting means rotates to the screwing side or the loosening side, the engaging member is likely to fluctuate, and there are many parts and the structure is extremely complicated. There are problems such as high costs.
[0008]
[Problems to be solved by the invention]
The strike of the sliding door lock of the present invention has been proposed for the purpose of solving the above problems. In short, the strike of the sliding door lock of the present invention simplifies the structure, reduces the number of parts, reduces the number of steps in assembly, and consequently reduces costs, and is also an engaging member for long-term use. It is intended to prevent fluctuation due to vibration from an appropriate position with respect to the strike frame of the adjusting member for positioning the.
[0009]
