Pick up device with telescoping tube
This invention provides hand operated portable adjustable length devices for grasping and manipulation of objects as well as methods of their use.
1. An adjustable length device to operably connect at least two components, the device comprising:
a) a cable having a first end and a second end;
b) a toothed rod having a first end and a second end, wherein the toothed rod comprises a plurality of teeth;
c) a toothed rod locking mechanism operably attached to the cable via a movable lever, wherein the movable lever comprises one or more teeth which can mate with the teeth of the toothed rod;
wherein movement of the cable causes the movable lever to operably engage or disengage with the toothed rod.
2. The device of claim 1 , wherein the toothed rod locking mechanism can be moved along the toothed rod when the movable lever is disengaged and is stationary on the toothed rod when the movable lever is engaged.
3. The device of claim 1 , wherein the adjustable length device comprises an adjustable length tube, which tube encloses the toothed rod locking mechanism, at least a part of the cable, and at least a part of the toothed rod.
4. The device of claim 1 , wherein the first end of the cable operably engages or disengages with the toothed rod via the mating of the movable lever of the toothed rod locking mechanism with the toothed rod and wherein the second end of the cable is operably connected to a trigger mechanism and wherein squeezing the trigger mechanism engages the movable lever of the toothed rod locking mechanism with the toothed rod.
5. The device of claim 1 , wherein the second end of the toothed rod operably engages or disengages with the cable via the movable lever of the toothed rod locking mechanism and wherein the first end of the toothed rod is operably connected to one or more additional components.
6. The device of claim 5 , wherein the one or more additional components comprise a pair of opposable jaw members.
