Abstract
A binding assembly includes first and second sheet retaining members which are releasably attached to a base member by first and second latching mechanisms. The sheet retaining members include a pair of side members which support a pair of pins and tubes onto which sheets of paper or other materials are placed. Each of the side members includes an engaging rod which is receivable in a channel provided in the base member to retain the sheet retaining members to the base member. Each of the latching mechanisms are independently pivotable about an axis perpendicular to the pins and tubes from a retaining position where the sheet retaining members are constrained to the base member, to a releasing position where the sheet retaining members may be detached from the base member.
Claims22
A binding apparatus comprising:
- a base member;
- a sheet retaining apparatus having at least one pin;
- one of said sheet retaining apparatus and said base member including an engaging rod;
- and
- a remaining one of said sheet retaining apparatus and said base member including a latching member for securing said sheet retaining apparatus to said base member, said latching member being pivotable from a retaining position where a portion of said latching member engages said engaging rod so that said sheet retaining apparatus is secured to said base member, to a releasing position where said portion of said latching member releases said engaging rod so that said sheet retaining apparatus may be detached from said base member.

A binding apparatus comprising:
- a base member;
- a sheet retaining apparatus having at least one pin;
- one of said sheet retaining apparatus and said base member including an engaging rod;
- and
- a remaining one of said sheet retaining apparatus and said base member including a latching member for securing said sheet retaining apparatus to said base member, said latching member being pivotable from a retaining position where said sheet retaining apparatus is secured to said base member, to a releasing position where said sheet retaining apparatus may be detached from said base member,
- wherein said sheet retaining apparatus includes said engaging rod, and said base member includes said latching member, and
