Abstract

A support device includes a base, a bracket for supporting an object, and an arm and a lever pivotally secured between the base and the bracket for forming a parallelogrammic structure. The arm is pivotally secured to the base with a shaft. The lever is secured to the base with a rod and has a curved groove for slidably receiving the shaft. The lever has an orifice for loosely receiving the rod. The base has a stop for engaging and latching the lever to the base, without additional fasteners, when the lever is elevated relative to the base.

Claims

1. A support device comprising:

a base,

a bracket for supporting an object,

an arm including a lower portion pivotally secured to said base with a shaft, and including an upper portion pivotally secured to said bracket with an axle, and including a curved channel formed therein and formed around said axle,

a lever including a lower portion pivotally secured to said base with a rod, and including a curved groove formed in said lower portion thereof and formed around said rod for slidably receiving said shaft and for allowing said lever to be rotated relative to said base, said lever including an upper portion pivotally secured to said bracket with a post, said post being slidably received in said curved channel of said arm for allowing said upper portion of said lever and said post to be rotated relative to said arm about said axle, and

means for selectively latching said lower end of said lever to said base after said arm and said lever are rotated and adjusted relative to said base.

2. The support device according to claim 1, wherein said selectively latching means includes an orifice formed in said lower portion of said lever for receiving said rod, said orifice of said lever includes an inner diameter greater than an outer diameter of said rod for loosely receiving said rod therein, and for allowing said rod to be moved relative to said base by sliding said rod upward and downward relative to said orifice of said lever.

3. The support device according to claim 2, wherein said selectively latching means includes a stop secured to said base for engaging with said lower portion of said lever and for locking said lever to said base when said rod moves upward relative to said orifice of said lever, said lower portion of said lever is allowed to be disengaged from said stop when said lever is elevated relative to said base and to move said rod downward relative to said orifice of said lever.

4. The support device according to claim 3, wherein said lever includes a peripheral flange formed and provided in said lower portion thereof and provided around said rod for engaging with said stop.

5. The support device according to claim 1 further comprising means for biasing said arm to elevate said bracket.

6. The support device according to claim 1 further comprising means for limiting a rotational movement of said arm relative to said base.

7. The support device according to claim 6, wherein said limiting means includes a stop secured to said base, and a curved passage formed in said lower portion of said arm for slidably receiving said stop.

8. The support device according to claim 7, wherein said arm includes a downwardly curved flap provided on said lower portion thereof for forming and defining said curved passage thereof.

9. The support device according to claim 1 further comprising a coupler pivotally secured to said bracket with a first pin, and a frame pivotally secured to said coupler with a second pin, said first pin being offset and perpendicular to said second pin, for allowing said frame and the object to be rotated and adjusted relative to said bracket.

10. The support device according to claim 1 further comprising a clamp rotatably secured to said base with a pivot spindle, for allowing said base to be rotated relative to said clamp about said pivot spindle.
