Method and apparatus for attaching display panels onto wall surface

A method for attaching flat screen display device which is selected from a group consisting of cathode ray tube, liquid crystal, plasma and light emitting diodes included in appliances selected from a group consisting of PC display, data display, graphic display, picture display, television receiver, video monitor, video interphone, video conferencing, video telephone, shopping terminal and a combination thereof, onto a recess mounting box embedded into a flat surface, which is selected from a group consisting of a wall, pole, partition, framework, skeletal structure, fence, bulkhead and a combination thereof, said recess mounting box including a spring guide plate for supporting a retractable holder using a plurality of retractable springs having arms and stoppers, rotatably jointed to said retractable holder and extended into complementary slots in said spring guide plate for guiding a movement of said arms and for compressing said springs during pull-out and for applying a released biasing force of said springs onto said arms against the inner surface of said spring guide plate for propelling said retractable holder toward said spring guide plate during a push-back of said display device toward said flat surface, wherein said retractable holder includes a plurality of springy electrical contacts and a plurality of hooks each having a latch, and a rear surface of said display device includes a plurality of corresponding electrical contacts and plurality of sockets each with a convex corresponding to said hooks each having a latch and wherein a front portion of said display device includes a frame, comprising the steps of:

• pulling out said retractable holder from said mounting box until said stoppers engage said slots, said springs are compressed and said arms are extended and forced against the outer surface of said spring guide plate for clutching said retractable holder in its pull out position;
• mounting said sockets onto said hooks and pushing said display device toward said box by overcoming the biasing force of said springy contacts;
• sliding said display device in a direction opposite to the direction of said hooks, until said springy electrical contacts engage said corresponding electrical contacts and every said convex is latched by every said latch;
• and
• pushing said display device attached to said retractable holder toward said recess mounted box by thrusting said arms inwards through said slots for releasing said clutching and for propelling said retractable holder toward said spring guide plate until said frame engages said flat surface.

A combination of flat screen display device which is selected from a group consisting of cathode ray tube, liquid crystal, plasma and light emitting diodes included in appliances selected from a group consisting of PC display, data display, graphic display, picture display, television receiver, video monitor, video interphone, video conferencing, video telephone, shopping terminal and a combination thereof, and a holder for attaching said display device onto a flat surface which is selected from a group consisting of a wall, pole, partition, framework, skeletal structure, fence, bulkhead and a combination thereof, said holder including a plurality of springy electrical contacts and a plurality of hooks each having a latch and the rear surface of said display device includes a plurality of corresponding electrical contacts corresponding to the plurality of springy electrical contacts and a plurality of sockets each with a convex corresponding to said hooks each having a latch wherein said display device is attached to said holder by mounting said sockets onto said hooks and pushing said display device toward said holder by overcoming a biasing force of said springy contacts and sliding said display device in a direction opposite to the direction of said hooks, until said springy electrical contacts engage said corresponding electrical contacts and every said convex is latched by every said latch, secured by said biasing force for preventing accidental release of said display device.

A combination of flat screen display device which is selected from a group consisting of cathode ray tube, liquid crystal, plasma and light emitting diodes included in appliances selected from a group consisting of PC display, data display, graphic display, picture display, television receiver, video monitor, video interphone, video conferencing, video telephone, shopping terminal and a combination thereof and a recess mounting box for mounting said display device into said box and onto a flat surface selected from a group consisting of a wall, pole, partition, framework, skeletal structure, fence, bulkhead and a combination thereof, said recess mounting box including a spring guide plate for supporting a retractable holder using plurality of retractable springs with arms and stoppers, rotatably jointed to said retractable holder and extended into complementary slots in said spring guide plate for guiding said arms movement during pull-out of said retractable holder from said mounting box until said stoppers engage said slots, said springs are compressed and said arms are extended and forced against the outer surface of said spring guide plate for clutching said retractable holder in its pull out position;

• said retractable holder includes plurality of springy electrical contacts and plurality of hooks each having a latch, and the rear surface of said display device includes plurality of corresponding electrical contacts and plurality of sockets each with a convex corresponding to said hooks each having a latch for mounting said sockets onto said hooks and pushing said display device toward said retractable holder clutched in said pull out position by overcoming a biasing force of said springy contacts and sliding said display device in a direction opposite to the direction of said hooks, until said springy electrical contacts engage said corresponding electrical contacts and every said convex is latched by every said latch and secured by said biasing force;
• said complementary slots further guide said arms movement during push back of said display device attached to said retractable holder by releasing said clutching and applying the released recoiling force of said springs onto said arms against the inner surface of said spring guide plate for propelling said retractable holder toward said spring guide plate, wherein the front portion of said display device includes a frame and pushing said display device attached to said retractable holder toward said recess mounting box by thrusting said arms back through said slots for releasing said clutching propels said retractable holder toward said spring guide plate until said frame engages said flat surface.
