Description

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 is attached to a door frame to lock a lock piece such as a latch bolt or a dead bolt attached to a door, and the lock position is adjusted. The present invention relates to a lock piece receiving device that can be used.

[0002]

2. Description of the Related Art Conventionally, as a lock receiving device capable of adjusting a locking position, there have been proposed a device of Japanese Utility Model No. 6-49780 and a device of Japanese Utility Model No. 6-43406. These devices have almost the same structure, and a protrusion provided at an eccentric position of the cam is fitted into the hole of the sliding box, and a screwdriver is engaged with an engaging groove provided on the protrusion to rotate the cam. By doing so, the sliding box is slid along with the protrusion for adjustment.

[0003]

In the above-mentioned conventional example, when the driver engages with the engaging groove of the protrusion and rotates,
Since the protrusion rotates leftward or rightward at the same time as the protrusion rotates, the center of rotation of the driver is not stable, and there is a problem that the operation is difficult especially when making fine adjustments.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a lock piece receiver in which a fitting for locking a lock piece is accommodated in a mounting box so as to be slidable laterally by a cam. In the device, the cam is rotatably supported by the mounting box, and the peripheral edge of the cam is in contact with the receiver, and the receiver is laterally slid by rotationally operating the operation portion provided at the eccentric position. It is composed in this way.

[0005]

When the operation portion of the cam is rotated by a tool such as a screwdriver, the cam rotates (it does not slide in the lateral direction but only rotates) and is in contact with the peripheral edge of the cam. Slides laterally.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The lock piece receiving device of the present invention comprises a mounting box 1,
It consists of a receiver 2, a surface plate 3 and a cam 4. Mounting box 1
Comprises a collar portion 8.8 provided on the upper and lower sides of the box portion 5, a circular shaft hole 7 is provided substantially at the center of the bottom plate 6 of the box portion 5, and mounting holes 9 and 9 are provided on the collar portion 8.8. I am doing it.

The receiver 2 is provided on both sides of the box 10 with an edge portion 17
17 is provided. A rectangular operation hole 12 that is long in the horizontal direction is provided in the center of the bottom plate 11 of the box portion 10 in the vertical direction, and the side walls 13 and 14 of the box portion 10 project slightly downward on both sides of the operation hole 12. The sandwiching plate portions 15 and 16 are provided. One of the sandwiching plate portions 15 is cut to almost the middle of the height of the side wall 13 to have elasticity, and the other sandwiching plate portion 16 is provided.
Does not have a notch, but is provided with sawtooth-shaped irregularities on the inner surface in order to increase frictional force. A sliding protrusion 18 is provided on the upper surface of one of the edge portions 17 so as to protrude upward.

The surface plate 3 is provided with a rectangular opening portion 19 at the substantially center thereof, and on one side thereof, the guide portion 2 which engages with the sliding projection portion 18.
The cutout 0 is formed so as to be continuous with the opening 19, and mounting holes 21 are formed in the upper and lower portions.

The cam 4 is a circular metal plate provided with a projecting shaft 22 projecting downward at an eccentric position, and a cross-shaped hole into which a Phillips screwdriver is engaged is provided on the upper surface thereof as an operating portion 23. The same saw-toothed concavo-convex is provided to engage with the concavo-convex of the sandwiching plate portion 16 of the receiver 2 to enhance the frictional force.

To assemble the present invention, the protruding shaft 2 of the cam 4 is used.
2 is loosely fitted in the shaft hole 7 of the mounting box 1, the receiving tool 2 is inserted into the mounting box 1 from above, the peripheral edge of the cam 4 is sandwiched by the sandwiching plate portions 15 and 16, and the surface plate 3 is formed on the surface thereof. Cover
The projections on the rear surface of the mounting holes 21/21 of the front plate 3 are caulked into the mounting holes 9/9 of the mounting box 1 and stopped.

The dimension between the inner surfaces of the sandwiching plate portions 15 and 16 is slightly smaller than the outer diameter of the cam 4, and the cam 4 is sandwiched by the resilience of one of the sandwiching plate portions 15 that is cut. , The concavo-convex on the inner surface of the other sandwiching plate portion 16 meshes with the irregularity on the peripheral edge of the cam 4, and when the cam 4 is rotated, the one sandwiching plate portion 1
Although 5 is elastically deformed slightly outward and rotates beyond the unevenness, it does not easily rotate during use.

To adjust, use a Phillips screwdriver on the cam 4
When it is engaged with the operation portion 23 and rotated, the peripheral edge of the cam 4 pushes either of the sandwiching plate portions 15 and 16 with which the peripheral edge of the cam 4 is in contact, and the receiver 2 slides to the left or right. At this time, the operating portion 23 only rotates and does not move laterally.

[0013]

As described above, according to the present invention, even if the operating portion of the cam is rotated by a tool such as a screwdriver, the cam does not slide laterally and the central axis of the tool does not move and is stable. Because
The effect is that delicate adjustments are easy.
