JPS6013964Y2 - Mounting bracket for surface-mounted lock - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a mounting bracket for a surface-mounted lock.

Conventionally, to attach a surface lock to a wooden door, it was either fixed directly to the door with wood screws, or by placing a plate with screw holes on the other side of the door and holding the door between the plate and the lock case. .

However, since the method of directly fixing the lock case with wood screws has a weak fixing force, there is a risk that the wood screws will come off and the lock case will be removed.

Furthermore, the method of holding the door between a plate having a screw hole and a lock case does not pose the risk of the lock case being removed, but there is a risk that the plate may be destroyed by prying open the gap between the plate and the door surface with a flat instrument.

Furthermore, since the board material is exposed outside the room, it not only has the drawback that the plants are not well-organized, but also the installation work is complicated.

The present invention aims to solve the above-mentioned drawbacks of the conventional method of attaching a surface-mounted lock.

That is, the present invention relates to a mounting bracket 1 for a surface-mounted lock, and by using the mounting bracket 1 of the present invention, it is possible to mount a surface-mounted lock that is easy to install, has high safety, and has a good appearance.

Embodiments of the present invention illustrated in the drawings will be described below.

(Description of Embodiments) In the drawings, reference numeral 1 denotes a mounting bracket which is bent into a U-shape as shown in FIG. 5 and has a screw hole 2.

A lock case 3 has a mounting hole 4, and a cylinder 5 is inserted into a through hole 13 passing through the door.

12 is the outdoor cylinder surface. The screw hole 2 of the mounting bracket 1 is bored at a position corresponding to the mounting hole 4 of the lock case 3.

On the other hand, a mounting bracket insertion hole 7 is bored in the door 6, parallel to the door surface, and perpendicular to the mounting hole 4 of the lock case 3 and the mounting hole 4 of the door 6.

(FIG. 2) 8 hides the mounting bracket insertion hole 7 of the door 6 with a decorative board.

10 is a mounting screw for the decorative board 8.

(Fig. 1) ■ To install a surface-mounted lock in this invention, first insert the mounting bracket 1 into the mounting bracket insertion hole 7 of the door 6, then place the lock case 3 on the door surface and screw the screw 9 into the lock case 3. Attachment Hole 4 Installation is possible by simply inserting the attachment hole 4a of the door 6 into the screw hole 2 of the attachment fitting 1.

(2) In the above embodiment, the mounting bracket 1 of the present invention was bent into a U-shape, but the mounting bracket 1 may be one or more plates or bars.

For example, two parallel fitting insertion holes may be bored from the end surface of the door 6, and one fitting may be inserted into each insertion hole.

Note that the decorative board 8 does not necessarily need to be attached.

(Effects of the present invention) The effects of the present invention are summarized as follows.

(2) By inserting the mounting bracket 1 of the present invention into the mounting bracket insertion hole 7 of the door 6, installation of the surface-mounted lock can be accomplished extremely easily by simply screwing in the screw 9 from the lock case 3.

■ Unlike conventional lock cases, the mounting hole of the lock case is not exposed to the outside, so it looks good, and the structure is strong and safe.
