Abstract

A liquid crystal display device protection structure for electronic equipment having an equipment cabinet made of a plastic material in which a liquid crystal display device is accommodated, the equipment cabinet formed with a viewing window so as to be faced with a display screen of the liquid crystal display device, comprises a reinforcing frame made of a material having a mechanical strength higher than that of the plastic material used for the equipment cabinet, and having a frame shape matched to a periphery of the viewing window, the reinforcing frame being integrally fixed to the equipment cabinet so as to be matched to the periphery of the viewing window, and a display screen protection cover which covers the viewing window and is mounted to the reinforcing frame.

Claims

1. A liquid crystal display device protection structure for electronic equipment having an equipment cabinet made of a plastic material in which a liquid crystal display device is accommodated, the equipment cabinet formed with a viewing window so as to be faced with a display screen of the liquid crystal display device, comprising:

a reinforcing frame made of a material having a mechanical strength higher than that of the plastic material used for the equipment cabinet, and having a frame shape matched to a periphery of the viewing window, the reinforcing frame being integrally fixed to the equipment cabinet so as to be matched to the periphery of the viewing window, and

a display screen protection cover which is mounted to the reinforcing frame and covers the viewing window.

2. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame has a box-like shape, and comprises:

a front plate that is developed so as to be matched to the display screen of the liquid crystal display device, and has an opening for exposing the display screen; and

side plates that are developed from an outer edge of the front plate to a direction along thickness of the front plate so as to surround an entire periphery of the liquid crystal display device.

3. The liquid crystal display device protection structure for electronic equipment of claim 2, wherein the reinforcing frame has four corners each of which is formed by the front plate and the side plates which are adjacent to each other, and the front plate and the side plates which are adjacent to each other are connected to one another.

4. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame is integrally fixed to the equipment cabinet by insert molding of the reinforcing frame to the equipment cabinet.

5. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame is integrally fixed to the equipment cabinet by hooking the reinforcing frame to claws provided at the equipment cabinet.

6. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame is integrally fixed to the equipment cabinet by welding the reinforcing frame to the equipment cabinet.

7. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame is integrally fixed to the equipment cabinet by using screws for fixing the reinforcing frame to the equipment cabinet.

8. The liquid crystal display device protection structure for electronic equipment of claim 1, wherein the reinforcing frame is integrally fixed to the equipment cabinet by hooking hooks provided at the reinforcing frame to the equipment cabinet.
