A handle assembly attachable to an object includes an auxiliary handle and a hook with a pivot arm pivotably attached thereto to define a passageway for the object. The pivot arm is pivotable between a first position, allowing access to the passageway, and a plurality of second positions, adjusting the size of the passageway to secure the object therein. A pawl, attached to the pivot arm, is movable between a first position, engageable with a ratchet of the hook, and a second position, disengaged therefrom. A shank extends the hook, and a clutch operatively couples the shank to the auxiliary handle. The clutch is actuatable between an engaged position and a disengaged position. The shank is moveable relative to the auxiliary handle in translation when the clutch is in the engaged position and the shank is rotatable relative to the auxiliary handle when the clutch is in the disengaged position. |

1. A handle assembly removably attachable to an object and graspable by a user's hand, the handle assembly comprising:
an auxiliary handle circumscribing a hand passageway to receive the user's hand therein; a hook and a pivot arm pivotably attached to the hook, the hook and the pivot arm defining an adjustably sized object passageway to receive the object, wherein the pivot arm is pivotable between a first position, allowing access to the object passageway, and a plurality of second positions, adjusting the size of the object passageway to secure the object therein; a ratchet positioned on the hook; a pawl attached to the pivot arm for pivoting therewith, the pawl being movable between a first pawl position in which a free end of the pawl is engageable with the ratchet, thereby preventing pivoting of the pivot arm toward the first position thereof, and a second pawl position in which the free end of the pawl is disengaged from the ratchet, thereby permitting pivoting of the pivot arm toward the first position thereof; a shank extending from an upper end of the hook, the shank having a longitudinal axis; and a clutch operatively coupling the shank to the auxiliary handle, the clutch being actuatable between an engaged position and a disengaged position, wherein the shank is moveable relative to the auxiliary handle only in translation along the longitudinal axis when the clutch is in the engaged position and the shank is rotatable relative to the auxiliary handle about the longitudinal axis when the clutch is in the disengaged position. |
