Patent ID: 8506200

Claim:
A rapid locking hand knob construct disposed between a first tube member and a second tube member slidably received within the first tube member, wherein the rapid locking hand knob construct is secured at an end portion of the first tube member by selectively engaging an area defining an aperture formed on the second tube member with a rib member formed on an interior surface of a stop block member, wherein the stop block member is selectively operable to be slidably received within the first tube member, wherein the stop block member is selectively operable to limit displacement of the second tube member relative to the first tube member, comprising: a first ring member, wherein the first tube member is selectively operable to be received in the first ring member; a first sleeve member, wherein the first ring member is selectively operable to be received within the first sleeve member; a seal ring member; a second sleeve member, wherein the seal ring member is selectively operable to engage a surface of the second sleeve member, wherein the first sleeve member is selectively operable to engage an area defining a groove formed on an exterior surface of the second sleeve member, wherein the first ring member is selectively operable to be received within the second sleeve member; a second ring member, wherein the second ring member is selectively operable to engage an area defining a groove formed on an exterior surface of the first ring member; a locking lining member, wherein the locking lining member is selectively operable to engage a surface of the stop block member; a third sleeve member, wherein the third sleeve member is selectively operable to engage an area defining a groove formed on an exterior surface of the locking lining member and is selectively operable to engage the second sleeve member; and a screw member; wherein the first ring member includes an area defining a groove formed on exterior surface thereof and a tapered surface formed on an inner surface thereof; wherein the locking lining member includes a tapered surface formed on an exterior surface thereof that is selectively operable to engage the tapered surface of the first ring member by rotation of the second sleeve member that moves the third sleeve member and locking lining member in an axial direction; and wherein the screw member is selectively operable to interconnect the first ring member, second sleeve member, and second ring member together.
