Abstract

A tool comprises housing, elongated member, trigger, first jaw, and second jaw. Housing comprises housing abutment surface. Elongated member comprises distal end, proximal end, and elongated-member abutment surface. Trigger is pivotally coupled to housing and is coupled to elongated member. Elongated member translates along axis when trigger is moved relative to housing. First jaw abuts housing abutment surface of housing and is configured to engage cable tie. First jaw is located between distal end of elongated member and housing abutment surface. Second jaw abuts elongated-member abutment surface and is configured to engage cable tie. Second jaw translates relative to first jaw along axis when trigger is pivoted with respect to housing.

First claim

What is claimed is:

1. A tool for releasing a cable tie that comprises a head, the tool comprising:
a housing, comprising a housing abutment surface;
an elongated member, at least a portion of which is located within the housing, and which comprises a distal end, a proximal end, and an elongated-member abutment surface;
a trigger, pivotally coupled to the housing and coupled to the elongated member so that the elongated membertranslates along an axiswhen the trigger is moved relative to the housing;
a fixed jaw, abutting the housing abutment surface of the housing, configured to engage the head of the cable tie from a first side of the head, and located between the distal end of the elongated member and the housing abutment surface of the housing so that the elongated member passes through the fixed jaw; and
a movable jaw, abutting the elongated-member abutment surface of the elongated member and configured to engage the head of the cable tie from a second side of the head, opposite the first side; and
wherein
the movable jaw translates relative to the fixed jaw along the axis when the trigger is pivoted with respect to the housing; and
the fixed jaw and the movable jaw are identical to each other, are located opposite each other along a central axis that passes along the elongated member and through the movable jaw and the fixed jaw, and are rotated 180 degrees with respect to each other about the central axis.

2. The tool of claim 1 , wherein:
the housing comprises a handle;
the trigger comprises a grip;
the trigger is pivotally coupled to the housing about a pivot axis;
the trigger is pivotally coupled to the elongated member about a coupling axis; and
the movable jaw is translated along the axis toward the housing abutment surface of the housing when the grip of the trigger is pivoted along a rotational direction toward the handle.

3. The tool according to claim 2 , wherein:
the housing comprises a handle stop surface; and
the trigger contacts the handle stop surface after a predetermined travel of the movable jaw.

4. The tool according to claim 1 , wherein:
the fixed jaw comprises a first base and a first positioning tooth, extending from the first base toward the movable jaw;
the first positioning tooth comprises a first-positioning-tooth distal end, spaced away from the first base;
the movable jaw comprises a second base and a second positioning tooth, extending from the second base toward the fixed jaw; and
the second positioning tooth comprises a second-positioning-tooth distal end, spaced away from the second base; and
the second positioning tooth of the movable jaw is identical to the first positioning tooth of the fixed jaw.

5. The tool according to claim 4 , wherein:
the fixed jaw further comprises a first opening tooth, extending from the first base toward the movable jaw;
the first opening tooth comprises a first-opening-tooth distal end, spaced away from the first base;
the movable jaw further comprises a second opening tooth, extending from the second base toward the fixed jaw;
the second opening tooth comprises a second-opening-tooth distal end, spaced away from the second base;
the second opening tooth of the movable jawis identical to the first opening tooth of the fixed jaw;
the first opening tooth of the fixed jaw is located opposite the second positioning tooth of the movable jaw; and
the second opening tooth of the movable jaw is located opposite the first positioning tooth of the fixed jaw.

6. The tool according to claim 5 , wherein the first opening tooth of the fixed jaw is different in size from the first positioning tooth of the fixed jaw and the second opening tooth of the movable jaw is different in size from the second positioning tooth of the movable jaw.

7. The tool according to claim 5 , wherein:
the fixed jaw further comprises a first pair of opposing jaw wings, extending from the first base; and
the movable jaw further comprises a second pair of opposing jaw wings, extending from the second base.

8. The tool according to claim 1 , wherein:
the housing further comprises a central cavity, extending along the central axis of the elongated member; and
the elongated member is disposed in the central cavity and extends along the axis within the central cavity.

9. The tool according to claim 8 , wherein:
the housing further comprises an assembly opening;
the elongated member further comprises a proximal member and a distal member;
the proximal member of the elongated member is configured to be inserted into the housing via the assembly opening ; and
the distal member of the elongated member is configured to be inserted into the housing via the central cavity.

10. The tool according to claim 8 , further comprising a base compression spring, disposed in the central cavity and configured to urge the distal end of the elongated member away from the fixed jaw.

11. The tool according to claim 8 , wherein the central cavity terminates in a central opening, configured to accept an insertion portion of the fixed jaw.

12. The tool according to claim 11 , wherein the central opening and the insertion portion of the fixed jaw are sized and configured for the insertion portion to be alternatively positioned in a first orientation within the central opening and a second orientation within the central opening.

13. The tool according to claim 11 , wherein the fixed jaw comprises an abutment surface, configured to contact the housing abutment surface of the housing when the insertion portion of the fixed jaw is inserted into the central opening.

14. The tool according to claim 1 , further comprising a jaw-compression spring, disposed between the fixed jaw and the movable jaw, wherein the jaw-compression spring is disposed about the elongated member and is configured to urge the fixed jaw and the movable jaw away from each other.

15. The tool according to claim 14 , wherein the jaw-compression spring biases the fixed jaw against the housing abutment surface of the housing and the movable jaw against the elongated-member abutment surface of the elongated member.

16. The tool according to claim 1 , wherein:
the housing comprises a grip;
the elongated-member abutment surface is located between the distal end and the proximal end of the elongated member;
the elongated-member abutment surface and the housing abutment surface face each other and the elongated-member abutment surface is movable relative to the housing abutment surface;
the movable jaw is interposed between the fixed jaw and the distal end of the elongated member; and
the movable jaw translates with the elongated-member abutment surface toward the fixed jaw and toward the grip along the axis when when the trigger is pivoted with respect to the housing toward the grip.

17. A tool for releasing a cable tie that comprises a head, the tool comprising:
a housing, comprising a grip and a housing abutment surface;
an elongated member, at least a portion of which is located within the housing, and which comprises a distal end, a proximal end, and an elongated-member abutment surface between the distal end and the proximal end;
a trigger, pivotally coupled to the housing and coupled to the elongated member so that the elongated member translates along an axis when the trigger is moved relative to the housing;
a fixed jaw, abutting the housing abutment surface of the housing and configured to engage the head of the cable tie from a first side of the head, and wherein the fixed jaw is located between the distal end of the elongated member and the hous
