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, locks a lock piece attached to the door, and can adjust the locking position. This is an improvement so that the lock piece can be securely locked even if the gap between the door frames, the so-called dust size, is large.

[0002]

2. Description of the Related Art Conventionally, various lock piece receiving devices capable of adjusting a locking position of a lock piece have been proposed. Processed and manufactured products have also been proposed.

[0003]

In the above-mentioned conventional example, a metal plate manufactured by pressing a metal plate has an advantage that it can be manufactured at low cost. If the edge of the ear edge bent outward at a right angle from is pressed, it becomes a large arc shape as shown in FIGS. 9 and 10 and the size of the dust between the door and the door frame. When the lock is large, the tip of the lock is applied to the arc-shaped part, and if a force is applied to the door to open it, the tip of the lock will move along the arc and retreat, causing the door to open. is there.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a lock receiving device in which a receiving member is slidably accommodated in a mounting box, wherein the receiving member is formed by pressing a metal plate. Then, a side wall for receiving the lock piece is erected from the bottom plate, an outer edge is provided at the upper end of the side wall to protrude outward, and the upper part of the side wall is cut and raised inward to form a contact part, and the tip of the contact part is It is substantially flush with the inner surface of the side wall.

[0005]

According to the present invention, the cut surface of the contact portion faces inward and is located at the edge of the edge of the receiving member and the corner of the side wall, so that the corner does not have a large arc shape. In addition, a sharply angled state having no extremely small arc-shaped or arc-shaped portions is obtained. Then, the lock piece can be received at the cut surface of the contact portion at the corner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. The lock receiving device includes a mounting box 1 embedded in a door frame, a receiving member 2 slidably received in the mounting box 1, and a surface plate 3 attached to the surface.

The mounting box 1 is provided with flanges 5 on the upper and lower sides of a box 4 provided in the center, and mounting holes 6 are drilled there.

The receiving member 2 is manufactured by pressing a metal plate, and has side walls 8.9 erected upward from both sides of a bottom plate 7, and ear edges 10 projecting outward from upper ends of the side walls 8.9, respectively.・ 1
1 is provided. At the connection corner between the one side wall 8 and the edge 10, there is provided an abutting part 12 in which the upper part of the side wall 8 is cut and raised inward. In order to form the contact portion 12, first, in a state of a flat plate before being bent, three sides around a rectangular portion serving as the contact portion 12 are cut out in a U-shape, and then bent at a right angle. Then, the contact portion 12 remains straight without being bent, and the tip thereof faces inward,
It is flush with the inner surface of the side wall 8.

The surface plate 3 is provided with a rectangular opening 13 substantially at the center and mounting holes 14 at the upper and lower portions.

To assemble the present invention, the mounting box 1
The receiving member 2 is accommodated in the box portion 4 of the
・ 14 correspond to the mounting holes 6.6 of the mounting box 1,
The surface plate 3 may be attached from the surface, and the assembled lock receiving device is inserted into the mounting holes 14 and 14 of the surface plate 3 and the mounting holes 6 and 6 of the mounting box 1 in the dug holes provided in the door frame. Attach with the screw through. In the present embodiment, the mechanism for sliding the receiving member 2 is omitted, but various mechanisms can be applied to the present embodiment.

The tip end surface of the abutment portion 12 of the receiving member 2 is not arcuate but square but has a large size between the door D and the door frame as shown in FIG. Even when the tip portion of L is received above the receiving member 2, the lock piece L is received by the contact portion 12 and is securely locked. On the other hand, according to the conventional example shown in FIGS. 9 and 10, when the size of the dust between the door D and the door frame is large and the lock L is received above the receiving member 41, the lock L Is received at the arc-shaped portion of the connection corner between the side wall 42 and the ear edge 43, and when wind or a person hits the door D and a force is applied in a direction to open the door D,
The tip of the lock L moves along the arcuate portion and retreats, and the door D opens.

A second embodiment of the present invention will be described with reference to FIGS. The lock receiving device includes a mounting box 21 embedded in a door frame, a receiving tool 22 slidably received in the mounting box 21, and a surface plate 23 attached to the surface.

The mounting box 21 is a box 2 provided at the center.
4 are provided with upper and lower flanges 25, 25, and mounting holes 26,
26 is drilled.

The receiving member 22 is manufactured by pressing a metal plate, and has side walls 28 and 29 erected upward from both sides of the bottom plate 27, and an edge 30 protruding outward from the upper ends of the side walls 28 and 29.
・ 31 is provided. At the connection corner between the one side wall 28 and the ear edge 30, there is provided a contact part 32 which cuts and raises the upper part of the side wall 28 inward and bulges upward. In order to form the contact portion 32, first, in the state of a flat plate before bending, three sides around a rectangular portion serving as the contact portion 32 are cut out in a U shape, or at the same time, The character-shaped portion is bulged upward, and then bent at a right angle. Then, the contact portion 32 remains straight without being bent, and the tip thereof faces inward, and the side wall 28
It is flush with the inner surface of

The surface plate 23 has a rectangular opening 33 substantially in the center.
And a guide portion 3 that engages with the contact portion 32 on one side.
5 is cut out so as to be continuous with the opening 33, and mounting holes 34 are formed in the upper and lower portions.

To assemble the present invention, the mounting box 2
The receiving member 22 is accommodated in the first box 24, and the mounting holes 34 of the surface plate 23 are attached to the mounting holes 26 of the mounting box 21.
And the guide portion 35 of the surface plate 23 is
Then, the surface plate 23 may be attached from the surface by engaging with the contact portion 32 of the second plate 2. 34 and the mounting holes 26 of the mounting box 21 with screws passing therethrough. In this embodiment, a mechanism for sliding the receiving member 22 is omitted, but various mechanisms can be applied to the embodiment.

In the second embodiment, as in the first embodiment, the tip end surface of the contact portion 32 of the receiving member 22 is not arc-shaped, but is square, so that the door D as shown in FIG. Even if the size of the dust between the door frame and the door frame is large and the tip end of the lock L is received above the receiving member 22, the lock L is kept in contact with the contact portion 32.
Is received and securely locked. Further, in the second embodiment, the contact portion 32 protrudes upward to the same plane as the surface of the front plate 23, so that the contact portion 32 is larger than in the first embodiment.
Is securely locked even if the hooking size of the lock L is small by the thickness of the lock.

[0018]

As described above, according to the present invention, while being an inexpensive pressed product, the abutment tip end face located at the edge of the receiving edge for receiving the lock and the corner of the side wall has a large circle. Without being arcuate, there is no very small arc or arc-shaped part, so it is sharply angled, so even if the dust size between the door to which the lock is attached and the door frame is large,
The lock piece is securely locked to the receiving member, and there is an effect that the door is not opened unintentionally.
