Abstract

The present disclosure is directed to an apparatus for use with an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the remaining parts of the adjustable wrench when the wrench fractures.

First claim

What is claimed is:

1. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
a handle having a handle end and a flat serrated jaw surface;
an L-shaped movable jaw having a hook portion, a lever arm, and a serrated jaw, the lever arm having a terminal end; and
a projection extending from the handle having a tunnel therein for accepting the lever arm of the L-shaped movable jaw;
wherein the restraint device includes a strip of material that extends around the lever arm and the hook portion of the L-shaped movable jaw.

2. The apparatus of claim 1 wherein the strip of material is fastened to itself or a portion of the L-shaped movable jaw.

3. The apparatus of claim 1 wherein the strip of material is constructed of materials selected from the group consisting of a metallic material, a polymeric material, or a combination thereof.

4. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
at least one handle;
a first jaw having a first gripping surface; and
a second jaw having a second gripping surface wherein the second jaw is movable with respect to the first jaw;

wherein the restraint device is a layer or strip of material disposed on a portion of the first or second jaw to limit the displacement of the broken portion of the adjustable wrench after the wrench fails.

5. The apparatus of claim 4 wherein the layer or strip of material is disposed completely around a portion of the first or second jaw.

6. The apparatus of claim 4 wherein the layer or strip of material is disposed on an outer portion of the first or second jaw.

7. The apparatus of claim 4 wherein a second layer or strip of material is disposed over at least a portion of the layer or strip of material.

8. The apparatus of claim 7 wherein the second layer or strip of material is comprised of a material selected from the group consisting of a polymeric material, an elastomeric material, a metallic material, a shrink wrap material, or a combination thereof.

9. The apparatus of claim 4 wherein the layer or strip of material is comprised of a material selected from the group consisting of a polymeric material, an elastomeric material, a metallic material, a shrink wrap material, or a combination thereof.

10. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
at least one handle;
a first jaw having a first gripping surface; and
a second jaw having a second gripping surface wherein the second jaw is movable with respect to the first jaw;

wherein the restraint device is an enclosure device that encapsulates a part of the first or second jaw to limit the displacement of the broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fails.

11. The apparatus of claim 10 wherein the enclosure device encapsulates substantially all of the first or second jaw while leaving the gripping surfaces of the first or second jaw exposed to engage a work object.

12. The apparatus of claim 10 wherein the enclosure device is secured to the handles or the first or second jaw.

13. The apparatus of claim 10 wherein the enclosure device is constructed of a material selected from the group consisting of a polymeric material, a fabric material, a cloth material, or a combination thereof.

14. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
at least one handle;
a first jaw having a first gripping surface; and
a second jaw having a second gripping surface wherein the second jaw is movable with respect to the first jaw;

wherein the restraint device is a rod element that extends through the first or second jaw.

15. The apparatus of claim 14 wherein the rod element is a bolt or a rivet.

16. The apparatus of claim 14 wherein the first jaw and the first gripping surface is disposed on one end of the handle and the second jaw is an L-shaped movable jaw having a hook portion, a lever arm, and a serrated jaw, the lever arm having a terminal end, wherein the rod element extends through the lever arm and the hook portion of the L-shaped movable jaw.

17. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
at least one handle;
a first jaw having a first gripping surface; and
a second jaw having a second gripping surface wherein the second jaw is movable with respect to the first jaw;

wherein the restraint device includes a C-shaped plate secured to the first or second jaw.

18. The apparatus of claim 17 wherein the C-shaped plate is secured to one side of a first handle and a corresponding side of the first jaw.

19. The apparatus of claim 17 wherein the first jaw and the first gripping surface is disposed on one end of the handle and the second jaw is an L-shaped movable jaw having a hook portion, a lever arm, and a serrated jaw, the lever arm having a terminal end, wherein the C-shaped plate includes a first end portion attached to the hook portion and a second end portion attached to the handle, the second end portion having a lip portion disposed thereon to contact a work object when the adjustable wrench fails.

20. The apparatus of claim 19 wherein the C-shaped plate further includes an extension element disposed on the second end portion having an elongated opening disposed therein and the handle has a pin element disposed thereon to engage with the elongated opening to permit the C-shaped plate to extend and retract as the L-shaped movable jaw extends and retracts.

21. A restraint apparatus, the apparatus comprising:
at least one restraint device attached to at least one part of an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the adjustable wrench after the adjustable wrench fractures, the adjustable wrench comprises:
at least one handle;
a first jaw having a first gripping surface; and
a second jaw having a second gripping surface wherein the second jaw is movable with respect to the first jaw;

wherein the restraint device includes a lanyard device attached to the first or second jaw and another part of the adjustable wrench.

22. The apparatus of claim 21 wherein one end of the lanyard device is releasably attachable to the adjustable wrench to facilitate the lanyard device's disposal around a work object for which the adjustable wrench is us
