Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bracket for engaging a latch bolt or a lock bolt of a lock when a door is closed.

[Conventional technology]

The engaging bracket for engaging the lock piece includes a bottom plate formed by pressing a metal plate, opposite side plates and end plates connected to the four side edges of the bottom plate and projecting to one side of the bottom plate, and both end plates. It is composed of a mounting piece that protrudes outwards from each other in a row and an immersion guide piece for a lock piece that protrudes outward from one side plate.The mounting method is to mount a receiving bracket in the recess provided in the door frame. After being inserted,
Wooden screws or screws are screwed into the door frame from the mounting piece.

[Problems to be solved by the invention]

When the door is closed, the ratchet bolts or detbolts fitted in the brackets and the side plate with the guide piece are not in contact with the door surface of the door frame when the door surface is not in close contact, for example, rattling may occur when wind pressure acts on the door. In order to prevent the rattling, the door contact surface side of the recess is engraved to widen the width and the adjustment is performed, which causes a problem in that it takes time.

In particular, when the door frame is made of metal, there is a problem that a tool such as a file is required and it is troublesome.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a mounting box having a rectangular concave portion inward from the surface, and is fitted into the concave portion and slides on both side plates facing each other on the left and right sides of the mounting box. A slide box having an open surface, a protrusion protruding toward one plate of the inner surface of the bottom plate of the mounting box, and a rotary shaft penetrating the bottom plate of the slide box so that the operating end is located in the box. A cam attached to the rotation shaft and brought into contact with the protrusion, a plate having an opening of the same shape that matches the opening of the slide box in the center, and pressing a flange protruding from the opening edge of the slide box. The plate is configured with insertion holes for mounting screws provided at the upper and lower edges of the plate.

If the latch bolts or dead bolts fitted in the slide box are loose when the door is closed, loosen the plate mounting screws to release the press-in of the slide box flange.

Next, when the cam is rotated by the rotating operation of the rotating shaft, the slide box is slid by the contact between the cam and the protruding shaft, and the inner surface of the side plate of the slide box is brought into contact with the latch bolt or the det bolt.

After that, tighten the screw and press the flange with the plate.

〔Example〕

In the figure, reference numeral 1 is a mounting box having a rectangular recessed portion from the surface to the inside.

The mounting box 1 is connected to the bottom plate 2, the left and right side plates 3.3 and the upper and lower end plates 4.4 which are continuous from the four side plates of the bottom plate 2 and are opposed to each other, and the both end plates 4.4. It is composed of projecting pieces 5.5 protruding outwardly from each other and an insertion hole 7 of a mounting screw 6 provided on both projecting pieces 5.

8 is a mounting box 1 so that it slides between the side plates 3.3.
It is a slide box with an open surface that is fitted into.

The slide box 8 is connected to the bottom plate 9, the side plates 10.10 and the end plates 11.11 connected from the four side edges of the bottom plate 9 to face each other, and the side plates 10. The flange 12.12 is made to project, and the above-mentioned flange 12.12 is adapted to overlap the opening edge of the side plate 3.3.

A protrusion 13 is provided on the inner surface of the bottom plate 2 of the mounting box 1 near one side plate 3.

Furthermore, the rotary shaft 14 is penetrated through the bottom plate 9 of the slide box 8 so that the operating end is located inside the slide box 8, and the rotary shaft 14 is provided with a cam 15 that is in contact with the protrusion 13. Has been.

The cam 15 is fixed by welding, for example, by fitting the square shaft 14 'of the rotary shaft 14 and the square hole 15' provided in the hole 15, and the operating end of the rotary shaft 14 is fixed to the screwdriver. It is formed by the head part.

The cam 15 is of a type in which the projection is in contact with the peripheral edge as shown in FIG. 1, and is of a type in which the projection is fitted in an arc-shaped long hole as shown in FIGS. 8 and 9. There is one.

Further, the slide box 8 always has the protrusion 13 and the cam 1
Although a pressing force is applied through the spring 16 so as to maintain the contact state with 5, the spring is not necessary in the case of the type shown in FIGS. 8 and 9.

Reference numeral 17 denotes a plate, which is screwed into the through hole 18 provided at the upper and lower edge portions of the plate 17 by screwing,
The slide box 8 is stopped by pressing the flange 12 between the plate 17 and the flange 19 which is continuous from the one side plate 3 of the mounting box 1 and projects outward.

Reference numeral 20 denotes a slightly larger opening having the same shape and provided in the central portion of the plate 17 so as to match the opening of the slide box 8.

As shown in the drawing, two notches 21 parallel to the plate 17 are provided, and two parallel protrusions 22 of the flange 12 are fitted in the notches 21 to slide the slide box 8. Can be smoothly guided.

Further, as shown in FIG. 1, by providing a wavy continuous concave-convex portion 23 into which the protrusion 13 is fitted, the peripheral edge slip of the cam 15 with respect to the protrusion 13 is stopped. be able to.

Next, the adjustment method will be described.

In order to move and adjust the slide box 8 stopped as shown in FIG. 4 due to the contact between the cam 15 and the protrusion 13 as shown in FIG.
After releasing the pressing of 2, the cam 15 is rotated by the rotation of the rotating shaft 14 to displace the contact position between the protrusion 13 and the cam 15 as shown in FIG. 7, and the spring 16 is compressed. Then, the slide box 8 slides to the right in FIG.

After that, the screw 6 is screwed in and the flange 12 is pressed by the plate 17.

〔effect〕

As described above, according to the lock receiving bracket according to the present invention,
When the screw is loosened to release the pressing of the flange, and the cam is rotated by rotating the rotation shaft, the slide box slides due to the contact between the cam and the projection, and the side plate of the slide box is attached to the latch bolt or the det bolt. Since it can be brought into contact with, it can be adjusted very easily without engraving the vertical frame, and rattling of the door can be prevented.

Further, since the projection is engaged with the concave and convex portion of the cam, the peripheral edge slip of the cam with respect to the projection can be stopped.

Therefore, the slide after the adjustment of the slide box can be reliably stopped.
