Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a post-lock structure for doors, etc., in which a thin front plate and a back plate are arranged at a predetermined interval.

Generally speaking, taking a door as an example, there are cases in which the post-drawing A is attached to the main body of the door B as shown in FIG. 1, and cases in which it is attached to the middle crosspiece of the frame sleeve as shown in FIG.

These are installed as shown in FIGS. 3-4.

That is, as shown in FIG.
1b at a predetermined position on door B.Next, place the postcard A into this notch hole 1, and insert the guide 2 from the opposite side.
(Fig. 6) into the notch hole 1, then insert the long fixing screw 3.
was screwed into the screw hole 4 provided on the back surface of the circumferential side of Posturo A and tightened.

5 is a liner provided around the notch hole 1, and a hole 5a corresponding to the hole 1a (or lb) into which the fixing screw 3 is inserted is provided.

When attaching the postcard constructed in this way to a door leaning against it, it is not easy to insert the long fixing screw 3 into the screw hole 4 provided on the back side of the postcard A.

That is, insert the long fixing screw 3 into the hole 2a of the guide 2 → the hole 1a (or lb) of the surface plate → the hole of the liner 5 in this order,
When the liner hole 5a on the boss drawer A side is approached, there is very little left of the long fixing screw 3 under the neck.

Furthermore, since the liner 5 is hollow in the middle, the tip of the fixing screw 3 tilts downward due to its own weight, making it difficult to guide it into the screw hole 4 on the back side of the postcard A.

Even if one fixing screw 3 is installed, it becomes even more difficult to locate the hole 1a (or 1b) on the other one.

In other words, for the first hole 1a (or lb), the tip of the long fixing screw 3 should be exposed to the opposite side, and then the screw hole 4 provided on the back side of the post-rotator A should be applied.
Since the liner 5 is close to the door, the tip of the fixing screw 3 must be carefully aligned with the hole in the liner 5 and the screw hole 4 when tightening the screw.

For this reason, there was a drawback that there was a large difference in work efficiency depending on the person.

The present invention attempts to solve the above problem.

FIG. 7 shows the mounting structure of the post-rotator according to the present invention, in which the post-role A is attached to the door B by means of a short fixing screw 7 through a connecting rod 6.

The connecting rod 6 has a male threaded portion 6a at one end and a threaded hole 6b at the other end.
is provided.

In order to attach Postro A to door B, insert the male threaded part 6 of the connecting rod 6 into the screw hole 4 previously provided on the back of Postro A.
Screw together a.

Next, if you hold the post drawer A and insert the joint rod 6 into the hole 1a (or lb) provided on both sides of the notch hole 1 of the door surface plate, the joint rod 6 will be attached to the post drawer A. Since it is erected at a right angle, it immediately passes through the hole in the liner 5 and protrudes an appropriate amount to the outside of the door back plate.

Therefore, align the insertion guide 2 with the joint rod 6,
It can be fixed using short fixing screws 7.

Since this work can be done visually, installation can be done quickly.

As described above, according to the present invention, instead of directly inserting the fixing screw into the mounting hole, the connecting rod 6 attached to the post-rotation A is inserted into the hole 1a or 1b drilled on both sides of the notch hole 1 and pushed in. Since it is only necessary to screw in the short fixing screw 7, the installation is extremely easy, and the post-rotation A can be installed efficiently.

Since it is a jointed rod, even if the thickness of the door differs, it can be easily accommodated by simply adjusting the length of the jointed rod to the appropriate size.
