Description

[Detailed Description of the Invention] The present invention relates to a built-in handle used for the case door of an electrical device.

Conventionally, a metal embedded handle has a mounting hole provided in the outer periphery of the flange, and is fixed to the door panel from the front of the panel with a screw passed through the hole. However, with this mounting method, the handle can be easily removed from the front side of the door by removing the screws, making it vulnerable to theft and mischief, and potentially causing dangerous electric shocks.

It is therefore an object of the present invention to provide a recessed handle that is resistant to removal from the front of the door. The gist of the present invention will be explained below with reference to the drawings. An inclined cam surface 7 is provided on the outer surface of the locking piece 6, and a receiving groove portion 3 is provided on the hole edge 2a of the handle attachment hole 2 of the door panel 1.
When the entire handle is pushed into the mounting hole 2, the cam surface 7 inclined with respect to the panel 1 is brought into sliding contact with the hole edge 2b of the mounting hole 2, and the elastic locking piece 6
By moving the handle 10 inward within the range allowed by the width of the groove 5, the entire handle 10 is embedded in the mounting hole, and the front end surface 6a of the locking piece 6 is elastically restored by passing through the mounting hole 2. is brought into contact with the hole edge 2b, and a pin 8 is inserted into the split groove 5 to prevent the locking piece 6 from moving inward again.

Therefore, with the embedded handle of the present invention, the contact between the mounting hole edge 2b and the front end surface 6a of the locking piece cannot be released unless the door panel 1 is opened and the pin 8 is extracted from the back side of the panel. Therefore, unauthorized or unnecessary removal of the handle from the front of the door is impossible.

Furthermore, in the handle of the present invention, the hole edge 2 of the mounting hole 2
Since the front end surface 6a of the elastic locking piece 6 that comes into contact with the panel 1 is inclined with respect to the panel 1,
Even if the thickness of the plate changes slightly, the locking piece 6 and the hole edge 2b
There is no possibility that contact with the object will fail. That is, the handle of the present invention can be attached to various door panels having different thicknesses in close contact with each other. In the illustrated embodiment, as shown in FIG. 4, a pin receiving part 9 with a radius of curvature that corresponds to the pin diameter is provided on the opposing inner surface of the split groove 5, and the pin 8 is inserted into this, so that the pin 8 is inserted into the split groove. 5 does not move in the length direction, and the re-movement of the locking piece 6 inward can be more accurately prevented. Note that the pin 8 does not have to be circular, but may be square, hexagonal, etc.; however, a protrusion is provided on the outer circumferential surface of the pin 8, and the protrusion
By making the inner surface bite into the pin receiving portion 9, it is possible to more firmly prevent the pin 8 from coming off. The side wall portion 4 including the elastic locking piece 6 may be molded integrally with the handle body 10, but in order to save material costs, it may be manufactured separately and then screwed, welded, or
They may be combined and integrated using an adhesive or the like.

Claims (1)

[Scope of utility model registration request] A receiving groove portion 3 that engages with the hole edge 2a of the handle attachment hole 2 of the door panel 1, and a side wall portion 4 on the opposite side of the receiving groove portion 3.
, an elastic locking piece 6 provided through a split groove 5 whose front end is open, an inclined cam surface 7 provided on the outer surface of the locking piece 6, and a pin 8 inserted into the split groove 5. The receiving groove portion 3 is engaged with the hole edge portion 2a,
When fitting the handle 10 into the handle mounting hole 2, the panel 1
The locking piece 6 is moved inward by sliding the cam surface 7 inclined to the hole edge 2b, and is elastically returned by passing through the mounting hole 2, so that the inclined front end surface 6a is brought into contact with the hole edge 2b. The embedded handle is configured such that a pin 8 inserted into the split groove 5 prevents the locking piece 6 that has come into contact with the locking piece 6 from moving inward again.
