A hand-held device for gripping objects positioned beyond arm's length, comprising a pair of jaws movable relative to each other between an unclamped position and a fully clamped position; a handle spaced apart from the jaws by a central portion, the handle including a trigger connected to the jaws

A hand-held device for gripping objects positioned beyond arm's length, comprising a pair of jaws movable relative to each other between an unclamped position and a fully clamped position; a handle spaced apart from the jaws by a central portion, the handle including a trigger connected to the jaws by a pull member, whereby actuation of the trigger is operative to move the jaws between the unclamped and fully clamped positions thereof, and a locking mechanism selectively operable to lock the jaws in at least one intermediate position defined between the unclamped and fully clamped positions; and wherein the pull member is sufficiently resilient so as to permit the jaws to be temporarily urged away from each other towards the unclamped position when the pair of jaws are locked in the at least one intermediate position.

The invention in which an exclusive property or privilege is claimed is defined as follows: 1. A hand-held device for gripping objects positioned beyond arm's length, comprising: a first pair of jaws movable relative to each other between an unclamped position and a fully clamped position; a handle spaced apart from said pair of jaws by a central portion, said handle including a trigger connected to said pair of jaws by a linkage, whereby actuation of said trigger is operative to selectively position said pair of jaws between the fully opened and fully closed positions thereof; wherein each of the pair of jaws includes a gripping portion freely removably connected thereto, wherein each of the pair of jaws includes an end effector having a bore in which the gripping portion is freely removably seated, wherein each of the gripping portions and bores are provided with complimentary male and female interlocking portions, whereby the gripping portions may each be securely freely removably seated in place within each of the bores, and wherein each gripping portion comprises an upper part having opposite gripping and seating surfaces, and a stem part extending axially from the upper part, the stem part including at least one radially extending tab, and wherein further each of the bores is dimensioned to receive therein the stem part, including the tab, each bore opening adjacent an upper surface opposing the seating surface of the gripping portion upper part, and each bore further communicating with a radiused slot dimensioned to receive therein the tab of the stem part to thereby permit rotational movement of the gripping portion relative to the jaw. 2. The hand-held device of claim 1, wherein the seating surface of each gripping portion includes at least one detent, and the upper surface of each of pair of jaws includes a complementary recess positioned at the limit of rotational movement of the gripping portion relative to the jaw. 3. In a hand-held device for gripping an object positioned beyond arm's length, the device including at least a pair of jaws for gripping an object therebetween, the at least pair of jaws movable relative to each other between a fully opened position and a fully closed position, a handle spaced apart from said at least pair of jaws by a central portion, said handle having a manually-actuatable trigger connected to said at least pair of jaws by a linkage operative to move said at least pair of jaws from the fully open to the fully closed positions thereof upon actuation of the trigger, and a locking mechanism selectively operable to lock said trigger into at least a first locked position thereof, and in which at least first locked position the at least pair of jaws define a first partially-closed position between the fully opened and fully closed positions, the improvement comprising: the linkage being a resilient linkage characterized in that the trigger can be moved into the at least first locked position thereof even when a gripped object prevents the at least pair of jaws from closing further towards the first partially closed position. 4. The hand-held device of claim 3, wherein the resilient linkage comprises a resilient pull rod. 5. The hand-held device of claim 4, wherein the resilient pull rod comprises a substantially inelastic pull rod including along the length thereof a resilient portion. 6. The hand-held device of claim 5, wherein the resilient portion of the pull rod comprises a spring. 7. The hand-held device of claim 6, wherein the pull rod is monolithic, and the spring is defined integrally therewith. 8. The hand-held device of claim 3, wherein the locking mechanism is selectively operable to lock said trigger into any of a plurality of locked positions thereof, and in each of which locked positions the at least pair of jaws define one of a plurality of partially closed positions between the fully opened and fully closed positions, and wherein the improvement further comprises the resilient linkage being characterized in that the trigger can be moved into at least one of the plurality of locked positions thereof even when a gripped object prevents the at least pair of jaws from closing further towards at least one of the partially closed positions thereof. 9. The hand-held device of claim 8, wherein the resilient linkage comprises a resilient pull rod. 10. The hand-held device of claim 9, wherein the resilient pull rod comprises a substantially inelastic pull rod including along the length thereof a resilient portion. 11. The hand-held device of claim 10, wherein the resilient portion of the pull rod comprises a spring. 12. The hand-held device of claim 11, wherein the pull rod is monolithic, and the spring is defined integrally therewith.
