Description

[Detailed Description of the Invention] The present invention relates to a structure in which a handle for opening and closing a door is attached to the front surface of a door panel of a switchboard or the like.

In the conventional handle mounting structure, a screw hole is provided on the mounting end surface of the No-Doll, and the screw hole is aligned with the mounting hole drilled in the door panel. The handle is tightened and fixed to the door panel by screwing a screw inserted into the mounting hole from the side into the screw hole.

However, with this installation method, it is necessary to simultaneously push the handle against the front side of the door panel and insert and screw in screws from the back side of the door panel.
Misalignment between the screw hole and the mounting hole is likely to occur before the screw is inserted or screwed in, so it was sometimes time consuming to install the handle.

Therefore, an object of the present invention is to provide a repurposed handle mounting structure that allows the handle to be mounted extremely easily and efficiently by a single operation from the front side of the door panel.

Another object of the present invention is to provide a mounting structure that can be applied to various door panels having different thicknesses.

Hereinafter, it will be explained based on the drawings that the mounting structure of the repurposed handle of the present invention includes a screw frame portion 3, which is connected to the screw frame portion 3, and whose outer diameter of the proximal end face 5 is the same as that of the mounting hole 2 of the door panel 1. A fastening tool 6 is used that is attached to a tapered cylindrical portion 4 that is larger than the diameter.

This fastening tool 6 is connected to the diversion handle 7 in advance by screwing the threaded frame portion 3 into the screw hole 9 of the attachment end surface 8 of the diversion bundle 7.

When the anchoring tool 6 is inserted into the mounting hole 2 from the front side of the door panel, the outer peripheral surface of the tapered cylindrical portion 4 is pressed by the hole wall of the mounting hole 2, and the vertically elongated groove 10 provided in the tapered cylindrical portion 4 is pressed. The tapered cylindrical portion 4 is elastically deformed in the diametrical direction by the intervention of.

After passing through the attachment hole 2, the base end surface 5 of the tapered cylindrical portion 4 whose diameter has been expanded and restored comes into contact with the back surface 1b of the door panel 1.

Then, the door panel 1 is held between the mounting end surface 8 of the diversion handle that comes into contact with the front surface 1a of the door panel 1.

Thus, the repurposed handle 1 is fixed to the front of the door panel.

As described above, in the mounting structure of the present invention, when the fastening tool 6 is screwed into the mounting end surface 8 of the diversion handle 7 and the fastening tool 6 is inserted into the mounting hole 2 from the front side of the door panel 1, the tapered cylindrical portion 4
is elastically deformed in the diametrical direction by the interposition of the longitudinally divided groove 10, and after passing through the attachment hole 2, the proximal end surface 5 of the tapered cylindrical portion 4 is restored to an outer diameter larger than the diameter of the attachment hole 2, and the base end surface 5 of the tapered cylinder portion 4 is repurposed. Since the door panel 1 is held between the mounting end face 8 of the handle and the mounting end face 8 of the handle, the work of mounting the repurposed handle 7 to the door panel 1 is as follows: pushing the anchoring tool 6 into the mounting hole 2 from the front side of the door panel. It is extremely simple, single operation, and can be carried out very efficiently at the installation site.

Furthermore, since the fastener 6 is connected to the diversion handle 7 by screwing into the screw hole 9 of the attachment end surface 8 of the diversion handle 7, by adjusting the screwing amount, the proximal end surface of the tapered cylindrical portion can be adjusted. 5 and the mounting end surface 8 can be increased or decreased.

Therefore, with the mounting structure of the present invention, it is possible to fit various door panels with different thicknesses without having to replace the fasteners.
This allows the repurposed handle to be attached accurately.

Although the present invention can be implemented in various ways, in the illustrated embodiment, the tip of the screw frame portion 3 of the fastening device 6 has an outer diameter equal to the diameter of the mounting hole 2; A slightly smaller cylindrical flange 11 is provided, and a cylindrical recess 12 is provided at the open end of the threaded hole 9 of the repurposed handle.

By tightly fitting the cylindrical flange 11 and the recess 12 into each other, the locking tool 6 is prevented from wobbling due to the gearing between the threads of the screw frame 3 and the screw hole 9, and the attachment of the repurposed handle 7 is prevented. It can be done very stably.

The large-diameter proximal end surface of the anchoring device is not limited to the circular shape as in the above embodiment, but may be a tapered cylindrical portion 140 with only the tip end having a tapered surface 13, as shown in FIGS. 5 and 6. A pair of tapered protrusions 15.15 may be provided at the base, and the distance between the outer end surfaces of these protrusions 15.15 may be smaller than the diameter of the mounting hole 2.
