JP2002043764A - Fall protection structure - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a fall protection structure of a front panel of electronic equipment in which closely-packed assembly can be realized easily, and maintenance and exchange of an operation panel unit can be easily done, and moreover, damages of the operation panel unit or hurts of human bodies due to falls during operation can be surely protected. SOLUTION: Attaching hooking metal fittings which have two or more steps protruding from the inside of a front panel on two or more positions of right and left, each hooking metal fitting protruding from the front panel is inserted in a square hole arranged on the operation panel unit. The first step of the metal fitting is hooked and held in a position so that the operation panel unit is fixed. The structure is considered so that the second or other step is used for protecting fall due to carelessness, and for transferring the operation panel unit to easily movable places and holding it.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation panel unit mounted on a front panel which can be opened and closed with a hinge as an axis, and it is necessary to carry out installation, maintenance and replacement of the operation panel unit with the front panel opened upward. The present invention relates to a fall prevention structure for an electronic device having a feature.

[0002]

2. Description of the Related Art Conventionally, screws are attached to a front panel,
The operation panel unit was provided with a ball-shaped hole to prevent it from being dropped by hooking it on the screw on the front panel, and the operation panel unit was fixed with the screw described above, but the screw was accidentally removed from the front panel Otherwise, the operation panel unit may be damaged due to the fall and may cause harm to the human body. Further, it has been difficult to perform operations such as a screw portion being located at a recessed position or a difficulty in moving an operation panel unit.

[0003]

SUMMARY OF THE INVENTION A high-density mounting of a front panel of an electronic device is possible, and maintenance and operation of an operation panel unit.
Provided is a fall prevention structure that facilitates replacement work and that can reliably prevent damage to an operation panel unit and harm to a human body due to a fall during work.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] A hook fitting provided with two or more steps projecting from the inside of the front panel is attached to the left and right sides.
At least three places are provided, and hooks protruding from the front panel are inserted into square holes provided in the operation panel unit, and hooked on the step.

The first step is hooked and held at a position where the operation panel unit is fixed. The steps after the second step are configured to prevent inadvertent dropping and to move and hold the operation panel unit at a position where it can be easily moved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 relate to a first embodiment of the present invention, and FIG. 1 is a schematic perspective view of the embodiment. The apparatus main body 1 and the front panel 2 are mounted via a hinge 7. 7, the front panel 2 can be opened and closed up and down. To prevent the front panel 2 from dropping when the front panel 2 is open, a gas spring 5 with a stopper is attached. Is locked and the front panel 2 does not fall,
The front panel 2 can hold an open state, and the operation panel unit 3 equipped with a touch panel, an LCD, and the like can be mounted.
Maintenance replacement work can be performed.

The front panel 2 is provided with two hooks 4 installed diagonally and protruding, and the operation panel unit 3 is provided with two square holes 10 corresponding to the hooks 4 provided on the front panel 2. There are two places.

In order to mount the operation panel unit, the square hole 10 is inserted into the hook fitting 4, and is hooked and held on the first step 9 provided on the hook fitting 4 shown in FIGS. At 6, the operation panel 3 is fixed. By making the protrusion amount L of the hook 4 higher than the height L2 of the front panel 2, the position of the hook 4 and the square hole 10 of the operation panel unit can be matched at a position where the operation panel unit 3 can be easily moved. Because it is possible, it can be hooked easily. The height L3 of the first step 9 is the minimum height at which the square hole 10 of the operation panel unit 3 is hooked in the direction of gravity G, and the amount of hooking movement is reduced to save space in the front panel. It is easy to hang and does not need to be always supported by hand, and the fixing screw 6 can be easily attached and detached.

FIGS. 4 and 5 show a first step 9 of the hook 4.
Indicates that the operation panel unit 3 is disengaged from the control panel unit 3. Thus, the second step 8 is provided, and the position of the second step 8 has no obstacle to the movement of the operation panel unit 3. By providing it at the position, the height of the step can be increased and the fall can be reliably prevented and safety can be ensured.

FIGS. 6 and 7 relate to a second embodiment of the present invention.
As shown in FIG. 6, two or more hook holes 4 and square holes 10 of the operation panel unit may be provided. As shown in FIG. 7, two or more steps 11 of the hook 4 may be provided.

[0012]

According to the present invention, the high-density mounting inside the front panel can be performed, and the operation panel unit can be easily mounted, and maintenance and replacement work can be easily performed. it can.
