Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle attachment device for electrical equipment.

Conventionally, a mounting device for attaching a handle to the cabinet of a television receiver includes a metal handle shaft, a cotter pin for fixing the handle shaft, and a moltoprene to prevent slight movement of the handle shaft and the cotter pin.
The handle shaft was made up of an insulating plate that was required to approach the high-pressure part (anode) inside the cabin because it was constrained to the center of gravity of the image receiver, but this required a large number of parts and was expensive. It had some drawbacks.

In view of the above points, the present invention aims to provide an inexpensive handle attachment device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The mounting device according to the present invention will be described as follows.
A rotating shaft 3 is integrally formed at the lower end of each elastic side piece 2 of a synthetic resin U-shaped handle 1, and the synthetic resin handle is integrally formed with the rear cabin B of the front and rear cabins A and B of the television receiver. A pair of left and right guide grooves 5 are formed in the mounting frame 4, and a shaft insertion hole 7 with an open upper part and a bearing hole 8 with one end communicating with the lower part of the insertion hole are formed in the side walls 6a, 6b of the grooves. The rotary shaft 3 is rotatably fitted and supported in the bearing hole, and electrically insulating retaining means 9 for preventing the shaft from being pulled out of the bearing hole 8 is provided.

Incidentally, a shaft rotation guiding protrusion 10 is integrally formed with an inclined shape on the inside of both side pieces 2 of the handle 1, and an arc-shaped guide protrusion for rotationally guiding the protrusion 10 is formed on the inner side wall 6a of the guide groove 5. 11 are integrally formed. The retaining means 9 is integrally formed with the protrusion 10, a protrusion retaining portion 12 formed at the front of the protrusion 11, and an outer portion of the frame 4 to prevent the shaft 3 from moving forward. Cantilevered elastic shaft retaining piece 1
3, and a retaining claw 14 formed at the tip of the retaining piece. Further, the handle 1 has a dimension from its axial center 3a to the lower end 2a of the side piece 2.
l ₁ is formed to have the same dimension as l ₂ from the axial center 8a of the bearing hole 8 to the bottom 6c of the guide groove 5, and is switchable between an upright position C and a collapsed position D. In addition, the protrusion 10 and the protrusion retaining portion 12 are as follows:
Slanted surfaces 10a and 12a are formed to facilitate fitting of the shaft 3 into the bearing hole 8, respectively.

In the above configuration, in order to attach the handle 1 to the mounting frame 4, the handle 1 is placed in an upright position C, and the rotating shaft 3 is inserted into the insertion hole 7 from above the mounting frame 4.
Insert into. Next, the rotating shaft 3 is moved toward the bearing hole 8 while maintaining the upright posture C of the handle 1.
Then, the protrusion 10 of the handle 1 rides over the retaining part 12 due to the outward elastic deformation of both side pieces 2 of the handle 1 while abutting against the inclined surface 12a of the protrusion retaining part 12, and the protrusion 10 of the handle 1 rides over the retaining part 12 by the outward elastic deformation of both side pieces 2 of the handle 1. It slides into the side wall 6a. At the same time, the rotating shaft 3 moves while elastically deforming the shaft retaining piece 13, engages with the retaining pawl 14, and is supported in the bearing hole 8 so that it cannot be withdrawn. The handle 1 rotates when the protrusion 10 moves along the guide protrusion 11 of the guide groove 5, and the handle 1 rotates when the protrusion 10 moves along the guide protrusion 11 of the guide groove 5.
4, the position of the rotating shaft 3 does not move and the handle 1
rotation is performed smoothly. And handle 1
is the dimension _l1 from the shaft center 3a to the lower end of both side pieces 2 from the center 8a of the bearing hole 8 to the bottom 6 of the guide groove 5.
Since the dimensions up to c are the same as _l2 , the handle 1 will not rotate more than 90 degrees, and when the handle 1 is attached to the mounting frame 4 and assembled, the handle 1 will not damage the front cabin A. Furthermore, the insertion hole 7 is covered by the front cabin A, preventing the handle 1 from being pulled out and dust from entering into the cabins A and B from the insertion hole 7.

As is clear from the above description, the present invention has a rotating shaft integrally formed at both ends of a U-shaped handle made of synthetic resin, and a pair of left and right guide grooves in a handle mounting frame made of synthetic resin for supporting the handle. A shaft insertion hole with an open top is formed in the side wall of each groove, and a bearing hole whose one end communicates with the lower part of the insertion hole is formed, and the rotating shaft is rotatably fitted and supported in the bearing hole. and is provided with an electrically insulating retaining means for preventing the rotating shaft from being pulled out of the bearing hole.

Therefore, according to the present invention, the rotating shaft is integrally molded into the handle, the handle and the mounting frame are made of synthetic resin, and the retaining means is insulated.
When used in electrical equipment, the insulation of the handle attachment part can be ensured, there is no need for an insulating plate as in the past, the number of parts can be reduced, costs can be reduced, and the time required to attach the handle can be shortened. It has excellent effects.
