Abstract

A Gripcut Tool comprises two shear bodies co-acting via a means of motion (e.g. a pivot hinge), wherein each shear body incorporates a cutting edge blade, a means of handling, and an integral gripping/holding component, the two shear bodies being arranged such that the active gripping surfaces of the first body are complementary to and fit against the active gripping surfaces of the second shear body when the tool is in the closed position, the Gripcut Tool being characterised in that at least part of the gripping surface/component of the first shear body intersects with and exists in the same plane at least part of the cutting edge of the first shear body (i.e. all or part of the cutting edge of the first shear body borders with/acts as a boundary to part of the gripping component of the first shear body), and further, characterised in that no part of the cutting edge of the second shear body intersects with, or acts as a boundary to the gripping component of the second shear body.

Claims

1. A Gripcut Tool comprising two shear-bodies co-acting via a means of motion (e.g. a pivot-hinge), each body incorporating a cutting edge blade, a means of handling, and a jaw/shank integrally, inflexibly and rigidly integrated with a gripping/holding component, arranged such that the active gripping surfaces of the first body are complementary to and fit against the active gripping surfaces of the second body when the tool is in the closed position, and characterised in that at least part of the gripping surface of the first shear body is intersected by and exists in the plane containing the cutting edge of the first shear body, wherein the gripping surface of the first shear body is bordered in part by the aforementioned cutting edge, and further, exist in the same plane as, or border the gripping surface of the second shear body;

2. as claimed in claim 1 wherein the gripping members exist on one or both planar sides of the device or of the cutting lades (thereby allowing gripping to occur on one or both sides), such that the longitudinal plane and longitudinal axis of gripping members is different to the plane and axis of the longitudinal length of the cutting blades, and the blade and gripping member are not arranged in line one behind the other;

3. a Gripcut Tool as claimed in claim 1 and 2 wherein the planes of the gripping surfaces of the gripping members may be flat, curved in one or more planes, arcuate, angled, non-rectilinear, rounded, some other shape, or a combination of these, and complementary to one another;

4. a Gripcut Tool as claimed in any preceding claim wherein the one of the two shear bodies is notched or otherwise shaped to accept the gripping member of the opposing shear body when the tool is in the closed position;

5. a Gripcut Tool as claimed in any preceding claim wherein the gripping member of one shear body is located between the upper (cutting-edge) border and the lower (non-cutting edge) border of that shear body, so as to allow contact of its gripping surface with that of the opposing shear body when the tool is closed;

6. a Gripcut tool as claimed in any preceding claim wherein the gripping surfaces of one or both of the shear bodies extend at an angle to the plane of the longitudinal axis of the shear body(s), said angle being less than, greater than, or the same as 90 degrees, or a combination of these;

7. a Gripcut Tool as claimed in any preceding claim wherein the blades cut and the gripping members grip at the same time, i.e. when the tool is brought from the open position to the closed position in a single closing motion;

8. a Gripcut Tool as claimed in any preceding claim wherein the gripping surface on only one of the two component shear bodies involves, at least in part, the upper border (cutting-edge border) of the shear body shank, adjacent to the cutting edge;

9. a Gripcut tool as claimed in any preceding claim wherein the co-acting gripping surfaces and gripping members match one another closely;

10. a Gripcut Tool as claimed in any preceding claim wherein the gripping members are not detachable or separate from the device;

11. A Gripcut Tool as claimed in any preceding claim wherein the gripping members may be mounted along part or all of the shank of the tool;

12. A Gripcut Tool as claimed in any preceding claim wherein the tool may be provided with more than one set of gripping elements, and where the two or more sets of co-acting gripping members may exist on the same planar side of the tool;

13. a Gripcut Tool as claimed in acclaim 4 wherein two or more sets of co-acting gripping members are provided, but where they are mounted on opposite planar sides of the tool, thereby allowing both of the two cut halves of the cut object to be gripped by the tool at the same time;

14. a Gripcut Tool as claimed in any preceding claim wherein the tool may be hand-operated or may be operated using a power-source (e.g. a battery);

15. a Gripcut Tool as claimed in any preceding claim wherein the pivot component is located at the handle'"'"'s free end (as in a pair of tweezers);

16. A gripcut Tool as claimed in any preceding claim wherein the means of motion may be a pivot such as a hinge;

17. A Gripcut Tool as claimed in any preceding claim wherein the pivot component at the blade-adjacent end of the handle (as in a pair of scissors);

18. a Gripcut Tool as claimed in any preceding claim wherein the blade non-adjacent ends are joined to one another(as found in the structure of a pair of tweezers);

19. a Gripcut Tool as claimed in any preceding claim wherein a secondary means of motion may be provided in the tool (in the case of a second pivot, it may exist with its axis parallel to or collinear with the axis of the first pivot);

20. a Gripcut Tool as claimed in any preceding claim wherein the lever arms (handles) may be located on the same side of the hub as the means of motion as the blade jaws and gripping members;

21. a Gripcut Tool as claimed in any preceding claim wherein the component blade edges, gripping members, shanks and lever arms may not exist in the same axial plane, and may also exist at an angle to one another, where this angle may be less than, greater than, or the same as 90 degrees;

22. A Gripcut Tool as claimed in any preceding claim wherein the co-acting gripping members are either similar in style, or are dissimilar in style;

23. a Gripcut Tool as claimed in any preceding claim wherein the gripping surfaces contact and fit against one another when the device is in the closed position;

24. a Gripcut Tool as claimed in any preceding claim wherein the lever arms may be located on the opposite side of the hub as the jaws and members;

25. a Gripcut Tool as claimed in any preceding claim wherein a gripping member is provided on only one of the two component shear bodies, being designed to fit against and grip against a pre-existing structural feature on the second, opposing, shear body, e.g. a gripping surface intended to engage with and fit against the notch found on some styles of suture scissors (in effect, the structural feature adopts the role of a second gripping member with a gripping surface);

26. a Gripcut Tool as claimed in any preceding claim wherein the opposing active surfaces of the gripping members that come into contact with each other, and which perform the gripping function when the tool is in the closed position, are smooth, serrated or otherwise patterned/shaped to facilitate and optimise the gripping action;

27. a Gripcut Tool as claimed in any preceding claim wherein the lever-arms (handles) may be rectilinear;

28. a Gripcut Tool as claimed in any preceding claim wherein the lever-arms (handles) may be non-rectilinear, and may be provided with one or more bends between their free ends and their hub-adjacent hub-portions;

29. a Gripcut Tool as claimed in any preceding claim wherein the said gripping members overlie one another;

30. a Gripcut Tool as claimed in any preceding claim wherein the cutting blades generally overlie one another;

31. a Gripcut Tool as claimed in any preceding claim wherein the level of the blade cutting edge on only one of the two co-acting shear bodies is the same as the level of the gripping surface on that same shear body;

32. a Gripcut Tool as claimed in any preceding claim wherein the gripping members and/or cutting blades are disposed side by side;

33. a Gripcut Tool as claimed in any preceding claim wherein the device incorporates a plurality of blade and gripping member arrangements;

34. a Gripcut Tool as claimed in any preceding claim, substantially as herein described, with reference to the embodiments, by way of example, as shown in the accompanying drawings.
