JPH08296353A - Face plate of strike - Google Patents

Abstract

PURPOSE: To prevent an accident, in which a body and clothes are caught, at low cost without scaling the whole in the face plate of a strike. CONSTITUTION: A strike 1 is composed of the two parts of a face plate 2 and a receiving box 3. The face plate 2 is made of a metal and a rectangular inserting hole 4, into and from which a lock pieces is taken, is bored at approximately a center and mounting faces to the upper and lower sections of the inserting hole 4 respectively while one side is bent slightly to the rear side to form a lip section 6. A plurality of strips of vertically continuously extended recessed strip grooves 7...7 are formed to a rear on the lip section 6 side. The receiving box 2 is manufactured by integrally molding a box body 9 having an opening section 8 in one surface and a collar plate 10 projected from the opening section 8 of a synthetic resin. Mounting holes are bored similarly at places corresponding to the mounting holes in the collar plate 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strike face plate which is attached to a door mounting frame, and is easily bent so that a lip portion does not protrude from the door mounting frame.

[0002]

2. Description of the Related Art The face plate of a strike may project from the mounting frame depending on the thickness of the mounting frame of the door, and if it projects, an accident may occur in which the body or clothing of a passing person is caught. is there. To prevent this accident,
Practical application Sho 62-142524 (Actual Kaihei 1-46358)
No.) is proposed. This invention is to provide a strike plate provided with insertion grooves facing each other vertically on the back surface side and having a ratchet mechanism in one of the insertion grooves, and a latch guide plate capable of being adjustedly inserted into the insertion groove. The gist of the present invention is a strike formed by forming serrated locking teeth on the latch guide plate.

[0003]

In the above-mentioned conventional example, there is a problem that the apparatus is complicated and the whole is large, and the cost is high.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a strike face plate having an insertion hole into which a lock piece is inserted and a lip portion on one side. Is provided with a groove groove extending in the vertical direction on the back surface of the.

[0005]

When the lip portion of the present invention, which is attached to the attachment frame of the door with wood screws, protrudes from the attachment frame, when the lip portion is hit with a hammer or the like, it is bent from the concave groove provided on the back surface.

[0006]

EXAMPLE A strike 1 is composed of two parts, a face plate 2 and a receiving box 3. The face plate 2 is made of a metal and has a rectangular insertion hole 4 into and out of which a lock piece 12 attached to the door 11 is inserted, and mounting holes 5 and 5 are formed above and below the insertion hole 4, respectively.
A lip 6 is formed by slightly bending one side to the back side. A plurality of grooves 7 extending continuously in the vertical direction are provided on the back surface of the lip portion 6 side.

The receiving box 2 is a box body 9 having an opening 8 on one surface.
The collar plate 10 projecting from the opening 8 is integrally molded of synthetic resin. The collar plate 10 is also provided with mounting holes (not shown) at positions corresponding to the mounting holes 5, 5.

In order to mount the present invention, a hole 14 for accommodating the box 9 is made in the mounting frame 13 of the door 11, and a perimeter of the hole 14 is engraved to a depth obtained by adding the thicknesses of the face plate 2 and the collar plate 10. And fasten with wood screws. At this time, when the lip portion 6 of the face plate 2 projects from the mounting frame 13, if it is hit with a hammer or the like, the face plate 2 is straightened from the concave groove 7 ... 7 as shown in FIG. 4 (B). Bent, lip 6
Adheres to the mounting frame 13.

[0009]

As described above, according to the present invention, by providing the recessed groove extending in the vertical direction on the back surface on the lip portion side, the lip portion protruding from the mounting frame can be bent easily and neatly. Thus, there is an effect that it is possible to prevent an accident in which a body or clothes is caught without increasing the size of the whole and at low cost.
