Abstract

A monitor tilting device capable of tilting the monitor using one hand. In an embodiment, the device comprises a cabinet bottom having a tilting opening at its rear lower surface, a monitor tilting member rotatably downwardly received in the tilting opening, a sliding washer rotatably receiving the upper section of the tilting member, and a torsion spring member elastically supporting the tilting member for supporting a tiled position of the monitor. In another embdiment, the device comprises a bracket integrally formed on the bottom surface of the monitor and a tilting member rotatably engaged with this bracket. In a further embodiment, the device comprises a monitor stand having a sliding depression, a sliding washer slidably coupled to an insert member of the sliding depression, and a bottom surface of the monitor fixedly coupled to the sliding washer. The monitor tilting device of this invention easily achieves the monitor tilting operation by simply pushing the monitor backwards using one hand, and causes easy fabrication of the monitor.

Claims

1. A monitor tilting device comprising:

a front case including a cathode ray tube therein;

a cabinet bottom, said cabinet bottom including a lower protrusion provided on a front lower surface of said cabinet bottom for acting as a point of the center of gravity of said monitor, a stationary support leg provided on a rear lower surface of said cabinet bottom for supporting the rear section of said bottom, a front sliding support shoulder, and an opposed pair of sliding side walls, each of said side walls extending upwards from each side of an inner surface of said cabinet bottom and having an arc-shaped sliding surface at its front edge, said sliding surface being bent backwards at its outer side in order to form an arc-shaped side surface and to define a slide guide groove;

a rear case slidably engaged with said cabinet bottom for tilting a monitor, said rear case including an arc-shaped sliding edge slidably engaged with said slide guide groove of the cabinet bottom, a lower shoulder extending forwards from a top of said sliding edge for limiting a backward tilting of said monitor in cooperation with a top of a corresponding side wall of the cabinet bottom, a first sliding surface extending outwards from said sliding edge, a boss mounted on said first sliding surface at a position under said lower shoulder, a second sliding surface extending inwards from said lower shoulder, and an upper shoulder extending backwards from a lower end of said second sliding surface for limiting a forward tilting of said monitor in cooperation with an upper panel of a back cover;

sliding washer means for elastically pressing said sliding surface of the cabinet bottom when said sliding edge of the rear case is slidably engaged with said slide guide groove of the cabinet bottom, said washer means including a screw hole for mounting this means on said boss of the rear case, and a pushing part for elastically pressing said sliding surface in order to support a tilted position of said monitor; and

said back cover for covering a rear section of said monitor, said back cover including said upper panel, a side panel and a rear panel.

2. A monitor tilting device comprising:

a front case including a cathode ray tube therein;

a cabinet bottom, said cabinet bottom including a lower protrusion provided on a front lower surface of said bottom for acting as a point of the center of gravity of said monitor, a stationary support leg provided on a rear lower surface of said bottom for supporting the rear section of said bottom, a front sliding support shoulder, and an opposed pair of sliding side walls, each of said side walls extending upwards from each side of an inner surface of said bottom and having a monitor tilting part provided on its front edge, and a sliding surface extending inwards from an inner surface of said side wall near said front edge, said monitor tilting part including upper and lower shoulders and a plurality of monitor tilting notches between said upper and lower shoulders, said sliding surface being bent backwards at its outer side in order to form a side surface and to define an arc-shaped slide guide groove;

a rear case slidably engaged with said cabinet bottom for tilting a monitor, said rear case including an arc-shaped sliding edge slidably engaged with said slide guide groove of the cabinet bottom, a sliding surface extending outwards from said sliding edge, and a boss mounted on said sliding surface;

sliding washer means for elastically pressing said sliding surface of the cabinet bottom when said sliding edge of the rear case is slidably engaged with said slide guide groove of the cabinet bottom, said washer means including a screw hole for mounting this means on said boss of the rear case, and a pushing part for elastically pressing said sliding surface, said pushing part being horizontally slit for elasticity and having a protrusion elastically engaged with one of said tilting notches of the cabinet bottom in order to support a tilted position of said monitor; and

a back cover for covering a rear section of said monitor, said back cover including an upper panel, a side panel and a rear panel.
