Telescoping support stand apparatus
View Patent ↗A telescoping support stand comprising an extendable leg that includes 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 locking mechanism attached to the second tube. The 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 include a plurality of extendable legs and a single release member that operates all of the locking mechanisms of the plurality of extendable legs. Corresponding methods of assembly and operation are also disclosed.
1. A telescoping support stand, comprising:
a handle assembly;
a first tube;
a second tube having a first end portion that telescopically slides within the first tube and a second end portion connected to the handle assembly;
a locking mechanism mounted to the first end portion of the second tube and operable to releasably secure the first tube to the second tube;
a release rod extending within the second tube from the handle assembly to the locking mechanism;
a release assembly mounted to the handle assembly and operable to move the release rod to operate the locking mechanism, the release assembly including a trigger and a displacement member interposed between the trigger and the release rod, the displacement member moving in its entirety in an axial direction upon operation of the trigger to move the release rod axially;
a first air exchange aperture at the second end portion of the second tube and configured to allow air to exit the second tube;
a second air exchange aperture defined at least in part by the locking mechanism and configured to allow air to flow between the first and second tubes.
2. The telescoping support stand of claim 1 , wherein the first air exchange aperture is accessed through a distal open end of the second tube.
3. The telescoping support stand of claim 1 , wherein the trigger is accessible outside the handle assembly.
4. The telescoping support stand of claim 1 , wherein the trigger includes first and second ends, the first end being pivotally attached to the handle assembly and the second end being movable radially inward and radially outward during operation.
5. The telescoping support stand of claim 1 , wherein the trigger is biased extending radially outward from the handle assembly to a position wherein the first tube is fixed axially relative to the second tube.
6. The telescoping support stand of claim 1 , wherein the trigger pivots about an axis arranged perpendicular to a length dimension of the first and second tubes.
7. The telescoping support stand of claim 1 , wherein the handle assembly includes a handle grip configured to be grasped by a user's hand while operating the trigger with the same hand.
8. The telescoping support stand of claim 1 , wherein the displacement member is movable longitudinally in the handle assembly.
9. A telescoping support stand, comprising:
a handle assembly;
a first tube;
a second tube having a first end portion that telescopically slides within the first tube and a second end portion connected to the handle assembly;
a locking mechanism mounted to the first end portion of the second tube and operable to releasably secure the first tube to the second tube;
a release rod extending within the second tube from the handle assembly to the locking mechanism;
a trigger mounted to the handle assembly;
a displacement member interposed between the trigger and the release rod, the displacement member moving in its entirety in an axial direction upon operation of the trigger to move the release rod axially.
10. The telescoping support stand of claim 9 , wherein the trigger is accessible outside the handle assembly.
11. The telescoping support stand of claim 9 , wherein the trigger includes first and second ends, the first end being pivotally attached to the handle assembly and the second end being movable radially inward and radially outward during operation.
12. The telescoping support stand of claim 9 , wherein the trigger is biased extending radially outward from the handle assembly to a position wherein the first tube is fixed axially relative to the second tube.
13. The telescoping support stand of claim 9 , wherein the trigger pivots about an axis arranged perpendicular to a length dimension of the first and second tubes.
14. The telescoping support stand of claim 9 , wherein the handle assembly includes a handle grip configured to be grasped by a user's hand while operating the trigger with the same hand.
15. The telescoping support stand of claim 9 , wherein the displacement member is movable longitudinally in the handle assembly.
16. The telescoping support stand of claim 9 , wherein the displacement member is carried by the trigger.
17. The telescoping support stand of claim 9 , further comprising a first air exchange aperture at the second end portion of the second tube and configured to allow air to exit the second tube.
18. The telescoping support stand of claim 17 , further comprising a second air exchange aperture defined at least in part by the locking mechanism and configured to allow air to flow between the first and second tubes.
19. The telescoping support stand of claim 17 , wherein the first air exchange aperture is accessed through a distal open end of the second tube.
20. A telescoping support stand, comprising:
a handle assembly;
a first tube;
a second tube having a first end portion that telescopically slides within the first tube and a second end portion connected to the handle assembly;
a locking mechanism mounted to the first end portion of the second tube and operable to releasably secure the first tube to the second tube;
a release rod extending within the second tube from the handle assembly to the locking mechanism;
a trigger pivotally mounted to the handle assembly;
a displacement member coupled between the trigger and the release rod and configured to move in its entirety axially toward the release rod upon operation of the trigger to move the release rod axially.
