Abstract

A clamp for use in a clamping and cutting device comprising a first leg (10), second leg (14) and third leg (22) which together form a cavity capable of receiving an object to be clamped when open, wherein the second leg (14) has a recessed section (20) such that the third leg (22) fits into the recessed section (20) when the clamp is closed, and a clamping and cutting device for clamping and cutting an object.

Claims

1. A clamp comprising:

a first leg having an inner face comprising a clamping bed,

a second leg attached at one end to the first leg at one end of said clamping bed by a resilient hinge by which the legs are sprung apart, said second leg having an inner face comprising a clamping bed extending part of the length of the inner face of said second leg from the hinge attached end of said second leg, and a recessed section extending from the clamping bed of said second leg to an opposite end of said second leg;

a third leg attached to said first leg at an opposite end of said clamping bed of the first leg by a resilient hinge by which the third and first legs are sprung apart, said third leg comprising a clamping bed extending the length of an inner face of said third leg, and a contact section on an outer face of said third leg;

wherein said first leg, said second leg and said third leg together form a cavity capable of receiving an object to be clamped,

wherein pressing said second leg towards the first leg against the resilience of the hinge joining them causes said recessed section of the second leg to contact said contact section on said third leg such that said third leg is pressed towards the first leg against the resilience of the hinge joining them,

wherein said recessed section is recessed such that said third leg fits into said recessed section when said clamp is closed,

wherein the clamping beds of said second and third legs together form a contiguous clamping bed for clamping a received object against the clamping bed of the first leg when said clamp is closed, and

wherein said first leg is parallel to said second and third legs when said clamp is closed.

2. The clamp as claimed in claim 1, wherein said first leg is extended beyond said third leg to form an elongate section.

3. The clamp as claimed in claim 2, wherein said elongate section is capped by a pusher section.

4. The clamp as claimed in claim 3, wherein said pusher section comprises a thumb engaging surface formed on an enlarged head portion.

5. The clamp as claimed in claim 2, wherein said elongate section comprises an abutment surface facing in the direction of said second leg.

6. The clamp as claimed in claim 1, wherein said clamp comprises a T-shaped rail incorporating a flange attached to an outer face of said first leg.

7. The clamp as claimed in claim 6, wherein said flange is spaced from the hinge of said second leg to form a resilient tail, wherein said tail comprises a tooth on an outer face of said flange, said tooth comprising an abutment surface facing in the direction of the third leg.

8. The clamp as claimed in claim 1, wherein said clamp comprises a rail attached to an outer face of the second leg.

9. The clamp as claimed in claim 1, wherein said clamp further comprises a catch mechanism for latching said first leg to said second leg when the clamp is closed.

10. The clamp as claimed in claim 1, wherein said clamp is molded from a plastics material.

11. The clamp as claimed in claim 1, wherein said cavity formed from said first leg, said second leg and said third leg is triangular-shaped.

12. The clamp as claimed in claim 1, wherein said clamping bed of the first leg and/or the clamping beds of the second and third legs comprise a row of teeth.

16. The clamping and cutting device as claimed in claim 13, wherein said first clamp is a clamp as claimed in claim 1.

13. A clamping and cutting device comprising:

a first clamp,

a second clamp including;

a first leg having an inner face comprising a clamping bed, a second leg attached at one end to the first leg at one end or said clamping bed by a resilient hinge by which the legs are sprung apart, said second leg having an inner face comprising a clamping bed extending part of the length of the inner face of said second leg from the hinge attached end of said second leg, and a recessed section extending from the clamping bed of said second leg to an opposite end of said second leg;

a third leg attached to said first leg at an opposite end of said clamping bed of the first leg by a resilient hinge by which the third and first legs are sprung apart, said third leg comprising a clamping bed extending the length of an inner face or said third leg, and a contact section on an outer face of said third leg;

wherein said first leg, said second leg and said third leg together form a cavity capable of receiving an object to be clamped,

wherein pressing said second leg towards the first leg against the resilience of the hinge joining them causes said recessed section of the second leg to contact said contact section on said third leg such that said third leg is pressed towards the first leg against the resilience of the hinge joining them,

wherein said recessed section is recessed such that said third leg fits into said recessed section when said clamp is closed,

wherein the clamping beds of said second and third legs together form a contiguous clamping bed for clamping a received object against the clamping bed of the first lea when said clamp is closed, and

wherein said first leg is parallel to said second and third legs when said clamp is closed,

wherein said first clamp comprises a first leg joined to a second leg by hinge at one end thereof and openable apart to receive an object to be cut,

a clamp holder comprising a blade and a plurality of slots that receive and support said first and second clamps side by side with said blade between them, said plurality of slots guiding said first and second clamps in a sliding movement within said clamp holder to advance said blade between said first and second clamps to cut said object in use whilst compressing the legs of said first and second clamps to clamp said object,

and a thumb engaging surface for sliding said clamps through said clamp holder.

14. The clamping and cutting device as claimed in claim 13, wherein said plurality of slots disengage from said first clamp when said first clamp is slid to a predetermined release point with respect to said clamp holder.

15. The clamping and cutting device as claimed in claim 14, wherein the first clamp can be removed from said clamp holder in two directions each orthogonal to the direction of said sliding movement.

17. The clamping and cutting device as claimed in claim 13, wherein said first clamp is a clamp as claimed in claim 9.

18. The clamping and cutting device as claimed in claim 13, wherein an abutment is provided obstructing removal of said first clamp by sliding movement thereof out of said clamp holder.
