Abstract

A binding mechanism assembly for binding a sheet item, the binding mechanism assembly including a backing member having an upper surface, and a binding member directly or indirectly coupled to the backing member. The binding member includes a protrusion shaped and located to protrude through a hole of a sheet item to be bound thereto. The binding member further includes a generally flexible flange that is manually movable into engagement with the protrusion to form a generally closed loop and thereby bind the sheet item thereto. The loop is rotatable relative to the backing member from a first position in which the loop is generally located above the upper surface to a second position wherein at least part of the loop is located below the upper surface. A release mechanism is provided for opening the loop.

First claim

The invention claimed is:

1. A binding mechanism assembly for binding a plurality of sheet items comprising:
a generally flat, planar backing member; and
at least one binding member directly or indirectly coupled to a support portion, wherein said support portion is directly or indirectly pivotally coupled to said backing member, said binding member including a protrusion shaped and located to protrude through a hole of a plurality of sheet items to be bound thereto, said binding member further including a generally flexible flange that is manually deformable to engage the protrusion to form a generally closed loop and thereby bind said plurality of sheet items thereto, said protrusion including an opening shaped to receive a distal end of said flange therein, wherein said loop is movable to a position wherein at least part of said closed loop is located below said backing member by pivotable movement of said support portion, said binding member further including at least one release mechanism moveable between a locked position and an unlocked position, the release mechanism comprising a locking feature to hold said loop closed in the locked position and to release said loop in the unlocked position.

2. The binding mechanism assembly of claim 1 , comprising a plurality of binding members.

3. The binding mechanism assembly of claim 2 , where said release mechanism when moved to the unlocked position releases all of the plurality of binding members simultaneously.

4. The binding mechanism assembly of claim 2 , where said release mechanism when moved to the unlocked position releases the plurality of binding members sequentially.

5. The binding mechanism assembly of claim 2 , further comprising an additional release mechanism, wherein the release mechanism is operatively coupled to at least some of said plurality of binding members, and wherein said additional release mechanism is operatively coupled to others of said plurality of binding members, and wherein said release mechanism and said additional release mechanism are independently operable.

6. The binding mechanism assembly of claim 5 , wherein the release mechanism and the additional release mechanism are located at opposed ends of the binding mechanism.

7. The binding mechanism assembly of claim 1 wherein said closed loop defines a plane, and wherein said binding member is rotatable about an axis oriented generally perpendicular to said plane of said closed loop.

8. The binding mechanism assembly of claim 7 wherein said binding member is rotatable about said axis at least about 15 degrees.

9. The binding mechanism assembly of claim 1 wherein said binding member and said backing member are made of a single monolithic piece of material.

10. The binding mechanism assembly of claim 1 further comprising a generally flexible transition portion coupled to and positioned between said backing member and said binding member such that said binding member is indirectly pivotally coupled to said backing member, wherein said flexible transition portion is deflected when said closed loop is rotated about an axis extending perpendicular to a plane defined by said closed loop.

11. The binding mechanism assembly of claim 10 wherein said support portion supports said protrusion and said flange, and wherein said transition portion is positioned between and coupled to said support portion and said backing member, wherein said support portion and said backing member each have a thickness adjacent to said transition portion, and wherein said transition portion has a thickness less than the adjacent thickness of both said support portion and said backing member.

12. The binding mechanism assembly of claim 1 wherein said backing member has a cut-out formed therein, and wherein said protrusion is located in said cut-out.

13. The binding mechanism assembly of claim 1 wherein when said closed loop is movable from a first position to a second position when said closed loop is pivoted in a first direction away from said backing member, wherein the binding mechanism assembly further includes a stop surface configured to limit significant pivoting of said binding member in a second direction that is generally opposite to said first direction.

14. The binding mechanism assembly of claim 1 wherein said flange is sufficiently flexible to be manually deflected to move said flange into and out of contact with said protrusion.

15. The binding mechanism assembly of claim 1 wherein said backing member has an upper surface, and wherein said binding member is movable by pivotable movement of said support portion to a position wherein said flange and said protrusion are both generally entirely located below said upper surface.

16. The binding mechanism assembly of claim 1 wherein said backing member has an upper surface, and wherein said closed loop is configured to be generally entirely located above said upper surface when no sheet items are bound thereto.

17. The binding mechanism assembly of claim 16 wherein at least part of said bound plurality of sheet items are pivotable about said closed loop to a position wherein said pivoted sheet items are located below said backing member, and wherein said loop is configured to be automatically moved to a position at least partially below said upper surface when said pivoted sheet items are located below said backing member.

18. The binding mechanism assembly of claim 16 wherein said flange includes a base portion oriented generally horizontally when all of said plurality of sheet items are located on a front side of said backing member, and wherein said base portion extends at least partially in a downward direction relative to said backing member when at least some of said pivoted sheet items are located below said backing member to thereby allow said pivoted sheet items to more fully underlie said backing member.

19. The binding mechanism assembly of claim 1 wherein said binding member is configured to bind a plurality of sheet items thereto, and wherein at least part of said bound plurality of sheet items are pivotable about said closed loop to a position wherein said pivoted sheet items are located below said backing member and the remainder of said plurality of sheet items are located above said backing member, and wherein said plurality of sheet items located below said backing member are generally parallel with said plurality of sheet items located above said backing member.

20. The binding mechanism assembly of claim 1 wherein said flange is directly coupled to said protrusion.

21. The binding mechanism assembly of claim 1 wherein said backing member has an inner edge extending generally parallel to a spine of said binding mechanism assembly, and wherein said support portion is pivotable relative to said backing member about a pivot axis, wherein said pivot axis is laterally spaced away from said inner edge.

22. A binding mechanism assembly for binding a plurality of sheet items comprising:
a backing member;
a binding member directly or indirectly coupled to said backing member, said binding member including a protrusion shaped and located to protrude through a hole of a sheet item to be bound thereto, said binding member further including a generally flexible flange that is manually deformable to engage the protrusion to form a generally closed loop and thereby bind said sheet item thereto, wherein said binding member is pivotally mounted relative to said backing member such that said binding member is pivotable
