Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a handle whose mounting direction can be determined with a single mounting screw.

Structure of the conventional example and its problems The conventional handle mounting structure is such that the handle B is attached to the door A with one mounting screw 1 or a plurality of screws 1, 1, as shown in Figures 1 and 2. If there is only one mounting screw 1 as shown in Figure 1, when a rotational force is applied to handle B, screw 1 will be removed as shown in Figure 3.
There is a drawback that the handle B becomes loose and the mounting direction cannot be determined, and the handle B comes off during long-term use. Also,
Even when the handle B is attached with the screw 1, there is a drawback that the direction of rotation is not determined because the handle B rotates in the direction of rotation of the screw. In addition, as shown in Fig. 2, a plurality of mounting screws 1,
If installing with 1, drill the mounting holes and screws 1, 1.
The tightening time becomes longer and costs increase.

Purpose of the invention The present invention is to eliminate the drawbacks of the above-mentioned conventional example.
To fix the installation direction of a handle, prevent it from coming off without loosening even when a rotational force is applied to the handle, and prevent the handle from rotating during installation work. Further, the purpose is to shorten the installation work and drilling time and provide the product at a low cost.

Structure of the invention In order to achieve the above object, the present invention provides a plurality of protrusions and recesses that fit into each other on the back surface of the handle and the surface of the mounting side base material. The back surface of the handle and the screw insertion hole of the mounting base material are configured to match, the handle is attached to the mounting base material with a single screw, and the plurality of protrusions and recesses are formed by a plurality of protrusions with different diameters. and a concave portion corresponding to this.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 6.

In FIGS. 4 and 5, reference numeral 2 denotes a metal handle, and a mounting seat 3 is formed at the rear of the handle 2. There are two protrusions 4 on the back side of the mounting seat 3.
a and 4b are provided. And one protrusion 4a
has a large diameter, and the other protrusion 4a has a small diameter. Further, a screw hole 8 is provided in the center of the mounting seat 3. 5
1 is a mounting side base material for a door or the like, and two recesses 6a and 6b are provided on the surface of this mounting side base material 5. Then, the concave portion 6a is made into a diameter hole into which the protrusion 4a is fitted,
The other recess 6b is a diameter hole into which the protrusion 4b is fitted. 7 is a mounting screw, and 9 is a screw insertion hole.

The handle 2 has the projections 4a and 4b of the mounting seat 3 fitted into the recesses 6a and 6b of the mounting base 5, and the screws 7
By tightening with , the mounting direction is determined and it is firmly fixed to the mounting side base material 5.

As described above, according to this embodiment, the protrusions 4a, 4b
And since the diameters of the recesses 6a and 6b are different,
The handle 2 can be moved from side to side, up and down, as well as from above and below, without worrying about each other's protrusions 4a, 4b and recesses 6a, 6.
The direction is determined just by fitting b, and the screw hole 8 and screw insertion hole 9 also match, so it is possible to prevent wrong installation of the handle 2 in the horizontal and vertical directions, and the work of tightening the screw 7 is extremely easy. be. Moreover, with only one screw 7, the handle 2 can be attached without rotating and without being oriented incorrectly. Further, even if a rotational force is applied to the handle 2 during use, since the protrusion 4 and the recess 6 are fitted together, the handle 2 will not rotate and the screw 7 will not loosen and the handle 2 will not come off. Furthermore, since only one screw 7 is required, the installation time can be shortened and the cost can be reduced. FIG. 6 shows another embodiment of the present invention, in which the relationship between the protrusion 4 and the recess 6 is reversed, which also achieves the effects of the present invention.

Effects of the invention As described above, according to the invention, the following effects can be obtained.

(1) Since it is fastened with a single screw, even if a rotational force is applied to the handle during use, it will not rotate due to the convex-concave fitting of the other side, and the screw will not loosen, allowing for strong use for a long period of time.

(2) The protrusion on the handle acts as a reinforcing member against shear stress and prevents the handle from falling off.

(3) Installation time can be shortened and costs can be reduced.

(4) Since the diameters of the multiple protrusions and recesses are different, mistakes in mounting the handle in the left/right and up/down directions can be prevented.
