Abstract

A load-adjustable display support device includes a support frame having opposite frame top and bottom ends, a sliding unit slidable along the support frame, and a load-adjusting unit disposed between the sliding unit and the support frame and including at least one tension spring and an adjustment member. The at least one tension spring can generate a tension force to bias the sliding unit to move between upper and lower limiting positions, where the sliding unit is proximate to the frame top and bottom ends, respectively. The adjustment member is disposed on the support frame and is operable to move a spring top end of the at least one tension spring along the length of the support frame for adjusting a tension of the at least one tension spring.

First claim

What is claimed is:

1. A load-adjustable display support device comprising:
a support frame including a main body that has opposite frame top and bottom ends and that defines a receiving space extending between said frame top and bottom ends;
a sliding unit disposed on said support frame and slidable along a length of said support frame, said sliding unit including a sliding member that is slidable in said receiving space and that has outer and inner surfaces, and a mounting seat disposed on said outer surface of said sliding member and configured for mounting a display thereon;
a load-adjusting unit disposed between said sliding unit and said support frame, and including at least one tension spring and an adjustment member, said at least one tension spring having a spring bottom end connected to said sliding unit, and a spring top end opposite to said spring bottom end and connected to said adjustment member, said at least one tension spring being configured to generate a tension force to bias said sliding unit to move between an upper limiting position, where said sliding unit is proximate to said frame top end, and a lower limiting position, where said sliding unit is proximate to said frame bottom end, said adjustment member being disposed on said support frame and being operable to move said spring top end along the length of said support frame for adjusting a tension of said at least one tension spring; and
a limiting member extending through said sliding member to tightly abut against said main body so as to position said sliding unit against said support frame, wherein:
said sliding member defines a passage that extends along the length thereof, and has a pair of through holes that are formed through said outer and inner surfaces thereof in proximity to a lateral edge of said sliding member, that are aligned with each other and that communicate with said passage;
said load-adjusting unit further includes a cover plate that is inserted through said passage and that covers said at least one tension spring and said adjustment member, said cover plate having a cutout that is formed in one lateral edge of said cover plate, that communicates with said pair of said through holes, and that has opposite top and bottom edges;
said limiting member extends through said pair of said through holes in said sliding member and said cutout in said cover plate to tightly abut against said main body of said support frame, said limiting member being loosenable to permit movement of said sliding member relative to said cover plate, and being movable along with said sliding member; and
said sliding member is movable relative to said cover plate between said upper limiting position, where said limiting member abuts against said top edge of said cutout, and said lower limiting position, where said limiting member abuts against said bottom edge of said cutout.

2. The load-adjustable display support device as claimed in claim 1 , wherein:
said support frame further includes a positioning seat that is fixed on said main body within said receiving space and that is proximate to said frame top end; and
said adjustment member is disposed on said positioning seat to move said spring top end toward or away from said positioning seat.

3. The load-adjustable display support device as claimed in claim 1 , wherein:
said load-adjusting unit includes two said tension springs, and further includes a bottom connection seat connected to said sliding unit, and a top connection seat spaced apart from said bottom connection seat;
said adjustment member threadedly extending through said top connection seat; and
said spring bottom ends of said tension springs are connected to said bottom connection seat, and said spring top ends of said tension springs are connected to said top connection seat.

4. The load-adjustable display support device as claimed in claim 3 , wherein said load-adjusting unit further includes a bottom fastener securing said spring bottom ends of said tension springs to said bottom connection seat, and a top fastener securing said spring top ends of said tension springs to said top connection seat.

5. The load-adjustable display support device as claimed in claim 1 , wherein said support frame further includes top and bottom plates that are respectively disposed on said frame top and bottom ends to cover top and bottom ends of said receiving space, and two decorative plates that are respectively disposed on two opposite lateral sides of said main body and that extend along the length of said support frame.

6. A load-adjustable display support device comprising:
a support frame including a main body that has opposite frame top and bottom ends and that defines a receiving space extending between said frame top and bottom ends;
a sliding unit disposed on said support frame and slidable along a length of said support frame, said sliding unit including a sliding member that is slidable in said receiving space and that has outer and inner surfaces, and a mounting seat disposed on said outer surface of said sliding member and configured for mounting a display thereon;
a load-adjusting unit disposed between said sliding member and said support frame, and including at least one tension spring and an adjustment member, said at least one tension spring having a spring bottom end connected to said sliding unit, and a spring top end opposite to said spring bottom end and connected to said adjustment member, said at least one tension spring being configured to generate a tension force to bias said sliding member to move between an upper limiting position, where said sliding member is proximate to said frame top end, and a lower limiting position, where said sliding member is proximate to said frame bottom end, said adjustment member being disposed on said support frame and being operable to move said spring top end along the length of said support frame for adjusting a tension of said at least one tension spring; and
a limiting member extending through said sliding member to tightly abut against said main body so as to position said sliding member against said main body;
said load-adjusting unit further including a cover plate that covers said at least one tension spring and said adjustment member, said cover plate having a cutout that is formed in one lateral edge of said cover plate and that has opposite top and bottom edges;
said limiting member extending through said sliding member and said cutout in said cover plate to tightly abut against said main body of said support frame, said limiting member being loosenable to permit movement of said sliding member relative to said cover plate, and being movable along with said sliding member;
said sliding member being movable relative to said cover plate between said upper limiting position, where said limiting member abuts against said top edge of said cutout, and said lower limiting position, where said limiting member abuts against said bottom edge of said cutout.
