Abstract

A side table includes a base unit, a top board, and a telescopic tube unit that is mounted to the base unit, and that includes an outer tube subunit, an inner tube subunit and a roller subunit. The outer tube subunit extends in an up-down direction. The inner tube subunit is coupled telescopically to the outer tube subunit. The roller subunit is mounted to the inner tube subunit, and includes a plurality of rollers that are in slidable contact with the outer tube subunit. The top board corresponds in position to the base unit in the up-down direction, and is mounted co-movably to the outer tube subunit such that a distance between the base unit and the top board in the up-down direction changes during telescopic operation of the telescopic tube unit.

First claim

What is claimed is:

1 . A side table comprising:
a base unit including a bottom board that has a first end part and a second end part opposite to each other in a front-rear direction; a telescopic tube unit mounted to said first end part of said bottom board of said base unit, and including
an outer tube subunit that extends in an up-down direction perpendicular to the front-rear direction, and that has
an outer surrounding surface,
an inner surrounding surface surrounded by said outer surrounding surface, and
a tube space defined by said inner surrounding surface,

an inner tube subunit that is coupled telescopically to said outer tube subunit, and that extends in the up-down direction into said tube space, and
a roller subunit that is mounted to said inner tube subunit, and that includes a plurality of rollers being in slidable contact with said inner surrounding surface of said outer tube subunit; and
a top board corresponding in position to said base unit in the up-down direction, and mounted co-movably to said outer tube subunit such that a distance between said base unit and said top board in the up-down direction changes during telescopic operation of said telescopic unit.

2 . The side table as claimed in claim 1 , further comprising a lifting unit that includes a pneumatic rod connected between said inner tube subunit and said outer tube subunit, and an actuating member that is operable for actuating operation of said pneumatic rod to extend and retract, thereby driving the telescopic operation of said telescopic tube unit.

3 . The side table as claimed in claim 2 , wherein:
said outer tube subunit includes
an outer tube having said outer surrounding surface and said inner surrounding surface, and
a top seat mounted to a top end of said outer tube, said top board being secured on said top seat; and
said actuating member of said lifting unit is mounted to said top seat, and is rotatable relative to said top seat between a free position, where said actuating member is separated from said pneumatic rod, and an abutting position, where said actuating member abuts against said pneumatic rod to actuate the operation of said pneumatic rod to extend and retract.

4 . The side table as claimed in claim 1 , further comprising at least one adjusting unit that includes
an adjusting seat surrounded by said inner tube subunit, movable relative to said inner tube subunit, and having at least one inclined surface that is inclined in the up-down direction, and that abuts against said roller subunit, an adjusting rod rotatably disposed in said inner tube subunit and extending in the up-down direction into said adjusting seat, and a threaded connecting member mounted to said adjusting seat and threadedly connected to said adjusting rod such that rotation of said adjusting rod relative to said threaded connecting member drives movement of said threaded connecting member along said adjusting rod, said adjusting seat being co-movable with said threaded connecting member relative to said adjusting rod in the up-down direction, such that movement of said adjusting seat in the up-down direction keeps said at least one of said rollers, via said inclined surface of said adjusting seat, staying in slidable contact with said inner surrounding surface of said outer tube subunit.

5 . The side table as claimed in claim 4 , wherein said roller subunit of said telescopic tube unit includes at least one pair of adjusting roller members that are spaced apart from each other in the up-down direction, each of said adjusting roller members including one of said rollers, said at least one inclined surface of said adjusting seat of said at least one adjusting unit including at least two inclined surfaces that are spaced apart from each other in the up-down direction and that respectively correspond in position to said at least one pair of said adjusting roller members.

6 . The side table as claimed in claim 5 , wherein:
said at least one adjusting unit includes two adjusting units that are spaced apart from each other in a left-right direction perpendicular to the front-rear direction and the up-down direction; said roller subunit of said telescopic tube unit includes a pair of stationary roller members that are mounted to said inner tube subunit of said telescopic tube unit, that are spaced apart from each other in the up-down direction, and that are in slidable contact with said inner surrounding surface of said outer tube subunit; and said at least one pair of said adjusting roller members of said roller subunit includes two pairs of said adjusting roller members, one pair of said adjusting roller members being arranged perpendicularly to the other one pair of said adjusting roller members, and being arranged to be spaced apart from said pair of said stationary roller members in the front-rear direction.

7 . The side table as claimed in claim 5 , wherein:
said at least one adjusting unit include two adjusting units that are spaced apart from each other in a left-right direction perpendicular to the front-rear direction and the up-down direction; said at least one pair of said adjusting roller members of said roller subunit of said telescopic tube unit includes two pairs of said adjusting roller members, said at least two inclined surfaces of said adjusting seat of each of said adjusting units respectively corresponding in position to a respective one pair of said adjusting roller members; said side table further comprises a lifting unit that includes a pneumatic rod connected between said inner tube subunit and said outer tube subunit of said telescopic tube unit, and being operable to extend and retract, thereby driving the telescopic operation of said telescopic tube unit; and said adjusting units are disposed respectively at opposite sides of said lifting unit.

8 . The side table as claimed in claim 4 , wherein said adjusting seat of said at least one adjusting unit has a through hole extending therethrough in the up-down direction, said through hole having
a first hole section and a second hole section that are located respectively at a top end and a bottom end of said adjusting seat, and an interconnecting section that interconnects said first hole section and said second hole section, a diameter of said interconnecting section being smaller than that of said second hole section, said adjusting seat further having an internal hole-defining surface that defines said first and second hole sections and said interconnecting section, said internal hole-defining surface having a stepped shoulder part at a junction of said interconnecting section and said second hole section, said threaded connecting member being located at said second hole section and abutting against said stepped shoulder part of said internal hole-defining surface.

9 . The side table as claimed in claim 4 , wherein:
said at least one inclined surface of said adjusting seat of said at least one adjusting unit includes a plurality of said inclined surfaces; said roller subunit of said telescopic tube unit includes a plurality of adjusting roller members that respectively correspond in position to said inclined surfaces, each of said adjusting roller members including a mounting seat that is mounted to said inner tube subunit, and one of said rollers that is rotatably mounted to said mounting seat, each of said inclined surfaces movably abutting against said mounting seat of the respective one of said adjusting roller members.
