Abstract

PURPOSE: To prevent movement in service of a receiving box, with which a lock piece is engaged, easily. CONSTITUTION: A lock piece receiver is composed of a face plate and a receiving box 2. The receiving box 2 is manufactured by integrally molding a box body 6 having an opening section in one surface and a collar plate 8 projected from the opening section of a synthetic resin. Slots 10, 10 for adjustment are bored at places corresponding to the mounting holes of the face plate in the collar plate 8. A large number of projecting section 11... 11 are formed around the rears of the slots 10, 10 for adjustment of the collar plate 8, and undercuts 12, 12 lower than the rear of the receiving box 2 at one stage are formed around the projecting sections. The projecting sections 11...11 are projected in height higher than the rear of the receiving box 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock piece receiving device which can be attached to a mounting frame of a door to adjust a position where a lock piece such as a latch bolt is locked. The inbox is improved so that it will not move easily during use.

2. Description of the Related Art Japanese Utility Model Application No. 61-15412
No. -131063) is a lock piece receiving device having a face plate and a receiving box, in which an uneven portion is provided on the back surface of the face plate and the front surface of the receiving box, and a receiving box to which lock pieces such as latch bolts are locked is provided. I keep it from moving.

[0003]

In the above-mentioned conventional example, there is a disadvantage that uneven portions must be provided on both the back surface of the face plate and the front surface of the receiving box, and since the receiving box is slid, there is some play around the periphery. It is necessary to have it,
If the face plate is slightly inclined with respect to the receiving box, the irregularities will not engage with each other, and if the screws are tightened in that state, the engaging portions of the irregularities will be damaged and the slip-prevention effect will be reduced. Also, since both the uneven parts are engaged,
The pitch of the uneven part will be adjusted as the minimum dimension,
If the pitch is small, the catch will be small and it will be slippery,
If it is large, there is a problem that fine adjustment cannot be performed. In any case, stepless adjustment is impossible. Further, since the face plate is usually made of a metal plate, the concave and convex portions on the back surface of the face plate are subjected to press working, and there is a problem that a mark of the working is also formed on the front surface side and the appearance is damaged.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a lock piece receiving device having a face plate and a receiving box, wherein the face plate has a through hole at substantially the center and mounting holes above and below the hole. The receiving box has a box body with an opening on one surface and a collar plate protruding from the opening.The collar plate is provided with an adjusting long hole at a position corresponding to the mounting hole of the face plate. A large number of protrusions are provided around the rear surface of the adjustment slot.

[0005]

In order to adjust the lock piece receiving device of the present invention mounted on the door mounting frame with wood screws, the wood screws may be loosened to move the receiving box, and then the wood screws may be tightened. When the wood screws are tightened, the protrusions provided around the rear side of the adjustment slot of the receiving box cut into the wood of the mounting frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention comprises two parts, a face plate 1 and a receiving box 2. The face plate 1 is made of metal, and the lock piece 1 of the door 13 is formed substantially at the center.
4 has a rectangular through hole 3 in and out, and mounting holes 5 above and below the through hole 3.
.5 are formed respectively, and the lock piece 14 of the through hole 3 is formed.
A rectangular recessed hole 4 is provided continuously to the through hole 3 on the side of the entry side.

The receiving box 2 is a box body 6 having an opening 7 on one surface.
And a collar plate 8 projecting from the opening 7 are integrally molded of synthetic resin, and the collar plate 8 is provided with adjusting long holes 10 and 10 at positions corresponding to the mounting holes 5 and 5. The projection 9 is provided at a position corresponding to the recessed hole 4 and protrudes to the same extent as the thickness of the face plate 1. Then, a large number of protrusions 11 ... 11 are provided around the rear surface of the adjustment elongated holes 10, 10 of the collar plate 8, and further provided with escape grooves 12, 12 that are one step lower than the rear surface of the receiving box 2 around them. is there. The protrusions 11 ... 11 project higher than the back surface of the receiving box 2.

To mount the present invention, a hole 16 having a size obtained by adding a space for adjustment to the width of the box body 6 is formed in the mounting frame 15 of the door 13, and the face plate 1 and the collar plate 8 are provided around the hole 16. Engraved to the depth of plus, and fastened with wood screws. Then, a large number of protrusions 11 ... 11 provided around the adjustment long holes 10 10 bite into the tree of the mounting frame 15 and are firmly fixed. Then, when the protrusions 11 ... 11 bite into the tree, the tree is pushed out and accommodated in the escape grooves 12.

[0009]

As described above, according to the present invention, since a large number of protrusions are provided around the rear surface side of the adjustment long hole, when the wood screw is tightened, the protrusion is separated from the head of the wood screw. It is located directly below, rather than in the vertical position, and the force that bites into the tree of the mounting frame acts strongly, and there is an effect that it can be firmly mounted.

Further, since it is only necessary to provide the protrusion on the back surface of the receiving box and the face plate does not need to be processed, the cost can be reduced and the appearance of the face plate is not unclean.

Further, since the protrusion provided on the back surface of the face plate bites into the tree of the mounting frame and is mounted, stepless adjustment is possible and fine adjustment is possible.
