Description

[Detailed description of the invention] This invention relates to an attachment device for a drop lock used when closing a gate or the like.

Conventionally, an end of the lower horizontal frame is brought into contact with a first side wall of a hollow vertical frame, a screw guide hole is bored in the second side wall of the hollow vertical frame, and a tapped hole is bored in the first side wall, and the screw Screws were inserted into the holes and screwed into the horizontal frame to connect the vertical and horizontal frames.

The screw guide hole in the second side wall was covered with a lid.

In addition, a drop lock was constructed from a combination of a backing plate, a drop bar, and a holding metal fitting, and was attached by a threaded part drilled into the lower end of a hollow vertical frame (Utility Model Application No. 111282/1983, Utility Model Application No. 52-2
No. 5195).

However, with such conventional mounting devices, mounting the lock is troublesome.

Furthermore, since many parts are used in the mounting device, product costs cannot be reduced.

Furthermore, there are also drawbacks such as the inability to provide a clean aesthetic appearance after installation.

This invention was devised in view of the above-mentioned drawbacks of the conventional methods, and cleverly utilizes the holes drilled to connect the horizontal and vertical frames of gates, etc., to improve the effectiveness of the drop lock installation device. To provide a drop lock mounting device which is simplified, can be easily mounted, and can also be adjusted.

Further, according to the drop lock mounting device according to the present invention, the mounting holes visible from the outside are self-closed without being covered, making it possible to provide a gate or the like with a good aesthetic appearance.

This invention will be explained below based on embodiments shown in the drawings.

First of all, referring to FIG. 3, a first screw hole 5 is bored in the first side wall 4 of the hollow vertical frame 3 against which the end 2 of the lower horizontal frame 1 comes into contact.

Then, the first screw 7 is inserted into the first screw "JL5" and screwed into the screw hole 6 of the lower horizontal frame 1 to connect the lower horizontal frame 1 and the vertical frame 3.

Further, a second threaded hole 10 having a diameter larger than the head 9 of the first screw 7 is bored in the second side wall 8 facing the first side wall 4 .

Therefore, to connect the lower horizontal frame 1 and the vertical frame 3, first, the first screw 7 is passed through the second screw hole 10 and inserted into the first screw hole 5.
Just screw it into the screw hole 6 of the lower horizontal frame 1 and tighten it.

At this time, the second screw hole 10 serves as a guide hole for the first screw.

By the way, the drop lock 11 includes a drop bar 12 and a drop bar 12.
A roughly H-shaped holding fitting 1 which is attached so as to be slidable up and down.
It is composed of 3.

The lock 11 is obtained by inserting the base 14 of the holding fitting 13 into the inner surface of the second side wall 8, inserting the second screw 15 into the second screw hole 10 via the washer 16, and attaching the base 14 of the holding fitting 13 to the inner surface of the second side wall 8. It is screwed into the female screw hole 18 of No. 14 and tightened, and is attached to the vertical frame 3 so as to be adjustable.

Here, the outer periphery of the threaded portion 17 of the second screw 15 may be configured to be approximately the same as the outer periphery of the threaded portion 17 of the first screw 7.

In the above configuration, the attachment of the lock attachment device according to the present invention will now be briefly described.

The end portion 2 of the lower horizontal frame 1 is brought into contact with the first side wall 4 of the hollow vertical frame 3 at a substantially right angle.

Next, the first screw 7 is inserted into the first screw hole 5 formed in the first side wall 4, and screwed into the screw hole 6 of the lower horizontal frame 1 to be fastened.

Next, the holding fitting base 14 of the lock 11 is attached to the inner surface of the second side wall 8 of the hollow vertical frame 3.

After that, the second screw 15 is inserted through the washer 16 into the second screw hole 10 bored in the second side wall 8, and the holding metal base 1
It is screwed into the female screw hole 18 of No. 4 and fastened.

By the way, the second screw hole 10 has a large diameter as described above, and is bored considerably larger than the diameter of the threaded portion 17 of the second screw 15.

Therefore, the lock 11 is installed in the second screw hole 10.
The hollow vertical frame 3 can be freely adjusted in the vertical and horizontal directions by the difference between the diameter of the hollow vertical frame 3 and the outer diameter of the threaded portion 17 of the second screw 15.

Thus, this invention has the above-mentioned configuration, but according to the drop lock mounting device according to this invention, by skillfully utilizing the screw holes for connecting the lower horizontal frame and the vertical frame, the drop lock mounting device This makes it possible to simplify the process, and the installation itself can be easily performed.

Furthermore, it is possible to provide a mounting device that allows mounting adjustment.

Further, the number of screw holes exposed on the outside can be minimized, and the holes are automatically closed, thereby providing a gate or the like with a good aesthetic appearance.

Therefore, the practical value of this idea is extremely high.
