A telescoping support stand comprising a first tube partially defining a first enclosed area and a second tube partially defining a second enclosed area. A first end of the second tube may be telescopically slidable within the first tube. The telescoping support stand may also comprise a first locking mechanism attached to the second tube. The first locking mechanism may releasably secure the first tube to the second tube to prevent longitudinal movement of the first tube relative to the second tube. The telescoping support stand may also comprise a first air exchange aperture dimensioned to allow air to flow between the first and second enclosed areas. The telescoping support stand may further comprise a release mechanism and a release rod attached to the first locking mechanism. The release mechanism may comprise a displacement member adjacent to the release rod, the displacement member being configured to displace the release rod and release the first locking mechanism. A corresponding method of assembly is also disclosed.

The telescoping support stand of claim 7, wherein the truncated-cone member is dimensioned to immobilize the bearings relative to an interior surface of the first tube when the bearing assembly is in the first position, the truncated-cone member being dimensioned to allow the bearings to move relative to the interior surface of the first tube when the bearing assembly is in the second position. 10. The telescoping support stand of claim 6, wherein the bearing assembly is movable between first and second positions relative to the truncated cone member. 11. The telescoping support stand of claim 6, wherein the truncated-cone member at least partially defines the first air exchange aperture. 12. The telescoping support stand of claim 6, wherein the bearing assembly at least partially defines the first air exchange aperture. 13. The telescoping support stand of claim 1, wherein the first locking mechanism at least partially defines each of the first and second enclosed areas. 14. The telescoping support stand of claim 1, wherein each of the extendable legs further comprises a release rod attached to the first locking mechanism and arranged in contact with the first displacement member. 15. The telescoping support stand of claim 14, wherein the first air exchange aperture comprises an opening in the release rod. 16. The telescoping support stand of claim 14, wherein the release rod is positioned at least partially within the second tube. 17. The telescoping support stand of claim 16, wherein the release rod is substantially longitudinally parallel to the second tube. 18. The telescoping support stand of claim 14, wherein the release mechanism is configured to displace the release rod of each extendable leg to release the first locking mechanism and allow longitudinal movement of the first tube relative to the second tube. 19. The telescoping support stand of claim 18, wherein the first displacement member is positioned adjacent to the release rods, the first displacement member being configured to displace the release rods. 20. The telescoping support stand of claim 19, wherein the first displacement member is configured to displace the release rod of all of the extendable legs simultaneously. 21. The telescoping support stand of claim 19, wherein the trigger being movable to cause the first displacement member to displace the release rods. 22. The telescoping support stand of claim 19, wherein the release rods are movable relative to the first displacement member. 23. The telescoping support stand of claim 19, wherein an end portion of the release rods contacts a surface of the first displacement member and is movable along the surface of the first displacement member. 24. The telescoping support stand of claim 19, wherein each of the extendable legs is movable relative to the first displacement member. 25. The telescoping support stand of claim 19, wherein an end portion of each of the extendable legs is rotatable about an axis proximate to the first displacement member. 26.
