Abstract

A support device includes a slide frame defining a receiving space that has an opening suitable for facing a wall surface, a sliding unit slidable on the slide frame and suitable for connection with at least one of a display screen and a work platform, and a load-adjusting unit disposed in the receiving space, connected to the slide frame and the sliding unit, and switchable between a movable state, in which it is movable and brings the sliding unit to move therealong, and a locked state, in which it generates a supporting force that supports the sliding unit to maintain at a desired fixed point. A control unit is disposed on the sliding unit and includes an operating member for controlling the movement of the load-adjusting unit.

First claim

What is claimed is:

1. A support device suitable for mounting on a wall surface and suitable for connection with at least one of a display screen and a work platform, said support device comprising:
a slide frame including a front plate extending along a length direction, and two side plates respectively connected to two opposite lateral sides of said front plate and spaced apart from each other in a width direction transverse to the length direction, said side plates and said front plate cooperatively defining a receiving space that has an opening suitable for facing the wall surface, each of said side plates further cooperating with said front plate to define a slide groove that has an opening opposite to said opening of said receiving space;
a sliding unit slidable on said slide frame in the length direction and suitable for connection with the at least one of the display screen and the work platform, said sliding unit having two sliding portions spaced apart from each other in the width direction, each of said sliding portions being slidably disposed in said slide groove defined by said front plate and a corresponding one of said side plates;
a load-adjusting unit disposed in said receiving space and connected to said slide frame and said sliding unit, said load-adjusting unit being switchable between a movable state, in which said load-adjusting unit is movable to extend and retract in the length direction and brings said sliding unit to move therealong, and a locked state, in which said load-adjusting unit generates a supporting force that supports said sliding unit to maintain at a desired fixed point, and
a control unit disposed on said sliding unit and including an operating member for controlling the movement of said load-adjusting unit;
wherein said load-adjusting unit is a locking cylinder, and includes a cylinder bad connected to said front plate, a piston rod retractably disposed in said cylinder body and connected to said sliding unit, and a valve stem extending through said piston rod and driven by said operating member, said valve stem being used for preventing retractable movement of said piston rod to place said load-adjustinq unit in the locked state and being also used for allowing retractable movement of said piston rod to place said load-adjusting unit in the movable state; and
wherein said front plate has a passage formed therethrough and extending in the length direction for communicating said receiving space with an external environment, said control unit further including a bolt rotatably inserted through said sliding member and said passage, said bolt having an eccentric portion located in said receiving space, and a drive portion opposite to said eccentric portion and connected to said operating member, said eccentric portion having a first contact face and a second contact face for contact with said valve stem, said first contact face and said second contact face having a position difference in the length direction, and wherein, when said first contact face contacts said valve stem, said first contact face presses said valve stern and allows said piston rod to extend and retract, and when said second contact face contacts said valve stem, said valve stem is released from being pressed, and said piston rod is prevented from extending and retracting.

2. The support device as claimed in claim 1 , wherein each of said side plates has a flank portion spaced apart from said front plate in the width direction, a plate-connecting portion connected between said front plate and said flank portion and cooperating with said front plate and said flank portion to define said slide groove, and a wall-connecting portion that is connected to a junction of said flank portion and said plate-connecting portion and that is suitable for connection with the wall surface.

3. The support device as claimed in claim 2 , wherein said slide frame further includes a plurality of decorative plates, said flank portion of each of said side plates having a first engaging portion formed on one end thereof, said wall-connecting portion of each of said side plates having a second engaging portion formed on one end thereof, each of said decorative plates being detachably connected to a respective one of said side plates and cooperating with the respective one of said side plates to define a wire-embedding space, each of said decorative plates having a third engaging portion and a fourth engaging portion formed on two opposite ends thereof, said third engaging portion engaging with said first engaging portion, said fourth engaging portion engaging with said second engaging portion.

4. The support device as claimed in claim 3 , wherein one of said first and third engaging portions is a protruding portion, and the other one of said first and third engaging portions is a recess portion, and wherein one of said second and fourth engaging portions is a protruding portion, and the other one of said second and fourth engaging portions is a recess portion.

5. The support device as claimed in claim 1 , wherein said sliding unit includes a sliding member slidable on said slide frame in the length direction and having said sliding portions, each of said sliding portions having an L-shape.

6. The support device as claimed in claim 5 , wherein said sliding unit further includes a mounting seat connected to said sliding member and suitable for connection with the display screen, and a pivot seat connected to said sliding member and suitable for connection with the work platform, said pivot seat being spaced apart from said mounting seat in the length direction, and being located at a height lower than that of said mounting seat.

7. The support device as claimed in claim 1 , wherein said control unit further includes a limiting cap connected to and cooperating with said sliding unit to define a first opening and a second opening for extension of said operating member therethrough, said first opening and said second opening being immediately adjacent to and communicating with each other, said limiting cap limiting the rotation of said operating member from said first opening to said second opening and vice versa.

8. The support device as claimed in claim 1 , wherein said control unit further includes a limiting assembly, said bolt further having two concave portions spaced apart by an angle, a range of the rotation of said operating member between said first opening and said second opening corresponding to said angle between said concave portions, said angle ranging from 60 to 100 degrees, said limiting assembly including a shaft seat, a ball and an elastic member, said shaft seat being connected to said sliding unit and having a through hole extending in the thickness direction for receiving said eccentric portion of said bolt, and a through slot extending in the length direction and communicating with said through hole, said through slot allowing said valve stem and said limiting assembly to pass therethrough in opposite directions, said ball being disposed between said elastic member and said eccentric portion of said bolt, said elastic member generating a biasing force for engaging said ball with any one of said concave portions.
