Rotatable handle attachable to an object having a longitudinal extent

摘要

A rotatable handle assembly attachable to a generally tubular object has an auxiliary handle circumscribing a hand passageway configured to receive a user's hand therein. A clutch biased in an engaged position operatively couples a shank extending from the upper end of a hook attachable to the object to a collar integrally formed as a portion of the auxiliary handle and releasably prevents the shank from rotating relative to the collar. A ratchet on the upper end of the hook cooperates with a pawl on a pivot arm which is attached to the lower end of the hook and which extends toward the ratchet and is rotatable about a transverse axis perpendicular to the longitudinal axis of the shank to adjust the size of the object passageway receiving and releasably retaining the object therein.

1. A rotatable handle assembly attachable to an object and graspable by a user's hand, the rotatable handle assembly comprising:
an auxiliary handle circumscribing a hand passageway configured to receive the user's hand therein; a collar integrally formed as a portion of the auxiliary handle;
a hook having an upper end and a lower end, the hook attachable to the object;a shank integrally formed with and extending from the upper end of the hook, the shank having a longitudinal axis;a clutch operatively coupling the shank to the collar, the shank moveable relative to the collar only in translation along the longitudinal axis when the clutch is in an engaged position;the shank movable relative to the collar in rotation about the longitudinal axis when the clutch is in a disengaged position, the clutch biased in the engaged position; anda ratchet on the upper end of the hook;a pivot arm attached to the lower end of the hook, the pivot arm extending toward the ratchet and rotatable about a transverse axis perpendicular to the longitudinal axis of the shank; anda pawl attached to the pivot arm for rotation therewith, the pawl slideable in translation relative to the pivot arm between a first pawl position in which a free end of the pawl engages the ratchet preventing rotation of the pivot arm and a second pawl position in which the free end of the pawl is disengaged from the ratchet, the pawl biased in the first pawl position.
