Abstract
A rotatable handle for use with a collet in a wet environment includes a body with an internal passage extending therethrough. The internal passage is at least partially threaded and the body is disposable on a threaded collet base. Upon rotation of the body relative to the threaded collet base, the body can selectively engage a collet such that the collet engages a tube, thereby selectively locating the tube. The body has a longitudinal axis along the passage, a major axis perpendicular to the longitudinal axis, and a minor axis perpendicular to the major axis. The body has a first length along the major axis and a second length along the minor axis, and the first length is longer than the second length.
Claims21
A rotatable handle for use with a collet in a wet environment, comprising:
- a body with an internal passage extending therethrough, the internal passage being at least partially threaded, the body being disposable on a threaded collet base, whereby upon rotation of the body relative to the threaded collet base, the body can selectively engage a collet such that the collet engages a tube, thereby selectively locating the tube;
- wherein the body has a longitudinal axis along the passage, a major axis perpendicular to the longitudinal axis, and a minor axis perpendicular to the major axis, wherein the body has a first length along the major axis and a second length along the minor axis, and the first length is longer than the second length.
An extension pole, comprising:
- an outer tube having a rear end, a front end, and a longitudinal axis;
- a collet base disposed on the front end of the outer tube and being at least partially threaded;
- a collet adjacent the threaded collet base;
- an inner tube with a front end and a rear end disposed at least partially within the outer tube and slidable relative to the outer tube along the longitudinal axis through the collet base and the collet;
- and
- a handle with an internal passage extending therethrough, the internal passage being at least partially threaded, the handle being disposed on the collet base, whereby upon rotation of the handle relative to the collet base, the handle selectively engages the collet such that the collet engages the inner tube, thereby selectively locating the outer tube relative to the inner tube;
- wherein the handle has a major axis perpendicular to the longitudinal axis and a minor axis perpendicular to the major axis, wherein the handle has a first length along the major axis and a second length along the minor axis, and the first length is longer than the second length.
