Claims
- 1. In a ring binder storing hole punched sheets of paper, the ring binder having first and second end leafs respectively forming outer covers of the binder, a plurality of binder rings which hold the sheets in their stored position, each binder ring including a fixed section and a movable section, and a movable bolt on which all of said movable binder ring sections are commonly mounted so to move in unison with the bolt, the improvement comprising:
- a lever arm attached to one end of said bolt for movement of said lever arm to move the bolt and the movable binder ring sections mounted thereon;
- a cover piece to which said bolt is movably mounted for both rotational and sliding movement of said bolt; and,
- latching means formed on said lever arm for latching said lever arm to an endwall of said cover piece and locking said bolt in place when said binder rings are closed thereby to prevent inadvertent movement of the lever arm which might cause the binder rings to open, said latching means including a projection formed on a face of said lever arm adjacent said endwall of said cover piece and extending toward said endwall, and a recess being in said endwall for receiving said projection.
- 2. The improvement of claim 1 wherein said recess has an upper wall surface which is a sloping surface and said projection includes a tab having a sloping surface which engages said sloping upper wall surface.
- 3. The improvement of claim 2 wherein said lever arm further includes means urging said tab against said upper wall surface of said recess.
- 4. The improvement of claim 3 wherein said projection is formed at one end of said lever arm and a lug is formed on a base of the lever arm at the opposite end thereof said lug bearing against a portion of the binder when the lever is captured in said recess.
- 5. The improvement of claim 4 further including a finger pad formed on said lever arm above said projection for depressing said lever arm to release said tab from said recess and allow said bolt to be moved.
- 6. In a ring binder storing hole punched sheets of paper, the ring binder having first and second end leafs respectively forming outer covers of the binder, a plurality of binder rings which hold the sheets in their stored position, each binder ring including a fixed section and a movable section, and a movable bolt on which all of said movable binder ring sections are commonly mounted so to move in unison with the bolt, the improvement comprising:
- a lever arm attached to one end of said bolt for movement of said lever arm to move the bolt and the movable binder ring sections mounted thereon;
- a cover piece to which said bolt is movably mounted for both rotational and sliding movement of said bolt;
- latching means formed on said lever arm for latching said lever arm to an endwall of said cover piece and locking said bolt in place when said binder rings are closed thereby to prevent inadvertent movement of the lever arm which might cause the binder rings to open;
- attachment means formed an underside of said cover piece for movably securing said bolt to said cover piece; and,
- storage means by which a user of said ring binder can store a writing instrument in said ring binder.
- 7. The improvement of claim 6 wherein said attachment means includes a recess formed on said underside of said cover piece and extending from one end of the cover piece to the other end thereof, said bolt snap fitting into said recess so as to be positively mounted therein for both rotatable and longitudinal movement.
- 8. The improvement of claim 6 wherein said storage means includes a flap formed on said cover piece and extending outwardly to one side thereof, a writing instrument being securable between said flap and an inner face of said binder cover to hold said writing instrument in place.
- 9. The improvement of claim 8 wherein said storage means includes a pair of spaced flaps are formed on said cover piece on a side of said cover piece opposite that on which said bolt is secured to said cover piece, each flap accommodating a separate writing instrument.
- 10. A ring binder storing hole punched sheets of paper comprising:
- first and second end leafs respectively forming outer covers of the binder;
- a binder ring mechanism including a plurality of binder rings which hold the sheets in their stored position, each binder ring including a fixed section and a movable section, a movable bolt on which all of the movable binder ring sections are commonly mounted so to move in unison with the bolt, and a cover piece to which said bolt is movably mounted for both rotational and sliding movement of the bolt; and,
- a lever arm attached to one end of the bolt for movement of the lever arm to move the bolt and the binder ring sections mounted on the bolt, said cover piece having a recess formed in an endwall thereof, and the lever arm having a latch member received in said recess to latch the lever arm in place when the binder rings are closed so to prevent inadvertent movement of the lever arm which might cause the binder rings to open, said latch member including a projection formed on a face of said lever arm said endwall of said cover piece and extending toward said endwall, and said recess being formed in said endwall for receiving said projection.
- 11. The improvement of claim 10 wherein said recess has an upper wall surface which is a sloping surface and said projection includes a tab having a sloping surface which engages said sloping upper wall surface.
- 12. The ring binder of claim 11 wherein said lever arm further includes means urging said tab against said upper wall surface of said recess.
- 13. The ring binder of claim 12 wherein said projection is formed at one end of said lever arm and a lug is formed on a base of the lever arm at the opposite end thereof, said lug bearing against a portion of the binder when the lever is captured in said recess.
- 14. The ring binder of claim 13 further including a finger pad formed on said lever arm above said projection for depressing said lever arm to release said tab from said recess and allow said bolt to be moved.
- 15. A ring binder storing hole punched sheets of paper comprising:
- first and second end leafs respectively forming outer covers of the binder;
- a binder ring mechanism including a plurality of binder rings which hold the sheets in their stored position, each binder ring including a fixed section and a movable section, a movable bolt on which all of the movable binder ring sections are commonly mounted so to move in unison with the bolt, and a cover piece to which said bolt is movably mounted for both rotational and sliding movement of the bolt;
- a lever arm attached to one end of the bolt for movement of the lever arm to move the bolt and the binder ring sections mounted on the bolt, said cover piece having a recess formed in an endwall thereof, and the lever arm having a latch member received in said recess to latch the lever arm in place when the binder rings are closed so to prevent inadvertent movement of the lever arm which might cause the binder rings to open;
- attachment means formed an underside of said cover piece for movably securing said bolt to said cover piece, said attachment means including a recess formed on said underside of said cover piece and extending from one end of the cover piece to the other end thereof, said bolt snap fitting into said recess so as to be positively mounted therein for both rotatable and longitudinal movement; and,
- storage means by which a user of said ring binder can store a writing instrument in said ring binder and including a flap formed on said cover piece and extending outwardly to one side thereof, a writing instrument being securable between said flap and an inner face of said binder cover to hold said writing instrument in place.
