Abstract

A computer table includes a circular fixed tabletop, a table frame, and at least one rotatable table unit. An annular guide rail is connected fixedly to an upper portion of the table frame, and is disposed under the fixed tabletop. The rotatable table unit includes: a rotatable tabletop having an inner end portion with a curved end surface which has a curvature radius the same as that of a periphery of the fixed tabletop and which abuts against the periphery of the fixed tabletop; at least one roller connected rotatably to the rotatable tabletop and movable along the guide rail; and a support frame connected fixedly to the rotatable tabletop and provided with a caster unit so as to permit rotation of the rotatable table unit about the fixed tabletop.

Claims

1. A computer table comprising:

a circular fixed tabletop;

a table frame including a fixed annular guide rail at an upper portion, said fixed tabletop being connected fixedly to said table frame, said annular guide rail being disposed under said fixed tabletop; and

at least one rotatable table unit including

a rotatable tabletop having an outer end portion and an inner end portion that is formed with a curved end surface which has a curvature radius the same as that of a periphery of said fixed tabletop and which abuts against said periphery of said fixed tabletop,

at least one roller connected rotatably to a bottom surface of said rotatable tabletop and adjacent to said end surface of said inner end portion of said rotatable tabletop, said roller being movable along said guide rail of said table frame, and

a support frame having an upper end that is connected fixedly to said bottom surface of said rotatable tabletop at said outer end portion of said rotatable tabletop, and a lower end that is provided with a caster unit which is adapted to be disposed on the ground so as to permit rotation of said rotatable table unit about said fixed tabletop.

2. The computer table as claimed in claim 1, further comprising a horizontal lower support plate, said table frame further including:

two front posts having upper end portions that are connected fixedly to said fixed tabletop;

two rear posts disposed behind said front posts and having upper end portions that are connected fixedly to said fixed tabletop;

two upper long rails, one of said upper long rails being connected fixedly to upper end portions of two of said front and rear posts, the other one of said upper long rails being connected fixedly to upper end portions of the other two of said front and rear posts, said upper long rails abutting against and being connected fixedly to a bottom surface of said fixed tabletop;

two lower long rails, one of said lower long rails being connected fixedly to said upper end portions of two of said front and rear posts, the other one of said lower long rails being connected fixedly to said upper end portions of the other two of said front and rear posts, said lower long rails abutting against and being connected fixedly to a bottom surface of said lower support plate; and

four short rails connected respectively and fixedly to said front and rear posts, each of said short rails extending in a radial direction of said fixed tabletop, said annular guide rail being disposed above and being connected fixedly to said short rails.

3. The computer table as claimed in claim 2, further comprising a horizontal upper support plate and a positioning device, said table frame further including two inverted L-shaped movable rods that are mounted telescopically to upper ends of said rear posts and that have upper ends which are connected fixedly to a bottom surface of said upper support plate, said positioning device being disposed between said movable rods and said rear posts for retaining each of said movable rods at a selected one of a plurality of positions relative to a corresponding one of said rear posts so that position of said upper support plate relative to said fixed tabletop can be adjusted.

4. The computer table as claimed in claim 1, wherein said support frame of said rotatable table unit serves as a compact disk-storing unit, and includes:

a U-shaped plate including

a vertical back wall having an upper end connected fixedly to said bottom surface of said rotatable tabletop, and

two parallel vertical sidewalls extending respectively, integrally, and perpendicularly from said back wall to define a compact disk-storing space between said sidewalls, each of said sidewalls having an inner side surface that is formed with a vertical row of outwardly and upwardly inclined ribs; and

an inverted U-shaped caster-supporting rod connected fixedly a lower end of said back wall and having two ends, said caster unit including two casters that are mounted respectively and rotatably on said ends of said caster-supporting rod.
