Abstract

A clip for securing sheet material comprising a base; a cam member operably connected to said base for displaceable movement between; an open position for insertion of said sheet material between said base and said cam member; a closed position for gripping said sheet material between said base and said cam.

Claims

1. A clip for securing sheet material comprising:
(a) a base;
(b) a cam member operably connected to said base for displaceable movement between (i) an open position for insertion of said sheet material between said base and said cam member;
(ii) a closed position for gripping said sheet material between said base and said cam.

2. A clip as claimed in claim 1 wherein said base extends outwardly from one edge thereof to present an arm wherein said cam member is rotatably connected to said arm for movement between said open and closed positions.

3. A clip as claimed in claim 1 wherein said base comprises a flat member presenting two spaced arms extending outwardly from one edge of said base, and wherein said cam member is pivotally connected to and between said spaced arms for pivotable movement between said open and closed positions.

4. A clip as claimed in claim 3 wherein each said arm includes a post and said cam member includes two spaced holes for receiving said posts respectively.

5. A clip as claimed in claim 3 wherein said arms including a rod extending between said arms and spaced from said base; and wherein said cam member includes a slot adapted to receive said rod for pivotal movement of said cam about said rod between said open and closed positions.

6. A clip as claimed in claim 1 wherein said base comprises two spaced leg members joined by a connecting member, each said leg member presenting an arm member extending from said leg members in the region remote from said connecting member, said members presenting a circular cross-section, and wherein said cam is pivotally connected to and between said spaced arm members for pivotal movement between said open and closed positions.

7. A clip as claimed in claim 1 wherein said cam member includes a tab operably movable at one end thereof and a cam at another end thereof.

8. A clip as claimed in claim 7 wherein said base presents an upstanding member at said one edge thereof merging with an opposing surface overlying said base, said opposing surface hingedly connected to said cram member for moving said cam member between said open and closed positions.

9. A clip as claimed in claim 8 wherein said base, upstanding member, opposing surface and cam member comprise of one piece plastic material, and said hinge connection comprises a reduction in thickness of said plastic material in the region between said cam member and said opposing surface remote from said upstanding member.

10. A clip as claimed in claim 9 wherein said opposing surface includes an opening for receiving said cam when said tab is operably movable from said open to said closed position.

11. A paper clip for securing paper comprising:
(a) first and second opposed surfaces, each having a forward and rear edge, and connected together at said rear edge, to permit insertion of said paper through said front edge between said first and second surfaces;
(b) a cam member pivotally connected to said front edge of said second surface for displaceable movement between:
(i) an open position where said cam member is displaced away from said first surface to permit insertion of said paper between said first and second surfaces, and (ii) a closed position where said cam member is displaced towards said first member to clamp said paper between said cam member and said second surface.

12. A paper clip as claimed in claim 11 wherein said second surface is substantially flat and includes an upturned forward edge presented by said first member to inhibit the accidental insertion of paper between said first and second surfaces in said closed position, and to deflect paper away from said paper clip in said closed position.

13. A paper clip as claimed in claim 12 wherein said first surface includes a raised portion between said front and rear edge to bend and assist trapping said paper in said closed position.

14. A paper clip as claimed in claim 11 wherein said cam member includes an operably movable tab at one end thereof and a cam surface at another end thereof.

15. A paper clip as claimed in claim 11 wherein said cam member includes an operably movable tab at one end thereof and (i) a first cam surface at another end thereof operably movable to a first closed position to clamp a first thickness of paper between said first cam surface and said first surfaces (ii) a second cam surface at another end thereof operably movable to a second closed position to clamp a second thickness of paper between said second cam surface and said first surface.

16. A paper clip as claimed in claim 11 wherein said second surface includes a recess for receiving said tab in said closed position, and said tab extends beyond said rear edge of said second surface in said closed position.

17. A paper clip as claimed in claim 11 wherein said second surface includes posts and said cam member includes holes for receiving said posts for pivotal movement thereabout.

18. A paper clip as claimed in claim 11 wherein said cam member is integrally connected to said front edge of said second member for rotational movement thereabout.

19. A method of clamping paper in a paper clip having spaced first and second opposed surfaces, each first and second opposed surface having a forward and rear edge, and connected together at said rear edge, and a cam member having a tab at one end thereof and a cam surface at another end thereof comprising the steps of:
(a) moving said tab to a first open position where said cam surface is displaced away from said first surface;
(b) inserting paper through said forward edge between the said first and second opposed surfaces;

(c) moving said tab to a closed position whereby said cam surface is displaced towards said first surface to clamp said paper between said cam surface and said second opposed surface.

20. A method as claimed in claim 19 wherein said paper is clamped by a desired number of said paper clips defining a binder along one edge of said paper to permit said paper to be separately moved about said one edge of said paper.
