Abstract
An expandable loose-leaf binder for releaseable insertion of perforated paper sheets consisting of two separate perforated covers joined by means of separate flaccid lace sheet retainers. Each retainer has a small, capsule-shaped connector which can be drawn through the sheet perforations and opened at any place in the binder to insert a sheet. An elastic band which may be adjusted or removed without releasing the retainers is used to take up slack.
Claims14
A loose-leaf binder for perforated paper sheets comprising,
- a first and second cover, each cover having a plurality of perforations proximate to an edge,
- at least two flaccid lace sheet retainers including a first and a second retainer, each retainer spaced apart from adjacent retainers and having connector members at opposed ends to selectively lock said opposed ends of the retainer, each retainer penetrating perforations of said first and second cover and locked at opposed ends to form an endless loop, and
- means for biasing each of said first and second retainers in the direction of the other, said means for biasing including an elastic band and a first and a second hook, said first hook connected to said elastic band and to the endless loop formed by said first retainer, said second hook connected to said elastic band and to the endless loop formed by said second retainer, each hook having a slit and a configuration permitting wrapping of said elastic band onto said hook, thereby altering the effective length of said elastic band.
A loose-leaf binder for perforated paper sheets comprising,
- a first and a second cover, each cover having a plurality of spaced apart perforations proximate to an edge,
- a back identification strip having a pair of parallel folds and having perforations along said folds, said perforations aligned with the perforations of said cover,
- at least two flaccid lace retainers, each of said lace retainers passing through aligned perforations of said first and second covers and said identification strip, each lace retainer having a male connector member and a female connector member joined together to form an endless loop,
- means for biasing a pair of spaced apart lace retainers toward an area between said lace retainers, said means for biasing including an elastic band and a first and a second hook, each hook connected to said elastic band and to an endless loop formed by a lace retainer of said pair of lace retainers, each hook having a slit and said elastic band wrapped through said slit at least one time, the number of wrappings about said slits of the hooks determining the effective length of said elastic band, and
- an elongate lacing needle having means for selectively coupling with one of said connector members of a lace retainer.

A loose-leaf binder for perforated paper sheets comprising,
- first and second parallel covers, each cover having a length and a width and a plurality of spaced apart perforations proximate a lengthwise edge,
- a back identification strip having a pair of parallel folds and having perforations along each fold, said perforations aligned with the perforations of said covers,
- a tension band folder positioned between said first and second covers, said tension band folder having a centerfold and a plurality of perforations proximate said centerfold, said perforations aligned with the perforations of the covers,
- at least two flaccid lace sheet retainers including a first and a second retainer, each retainer spaced apart from adjacent retainers and having a male connector member and a female connector member at opposed ends of the retainer, each retainer being laced through the perforations of said covers, said identification strip and said tension band folder, each retainer locked at said opposed ends to form an endless loop,
- means for biasing each of said first and said second retainer in the direction of the other, said means for biasing including an elastic band and a first and a second hook, said first hook connected to said elastic band and to the endless loop formed by said first retainer, said second hook connected to said elastic band and to the endless loop formed by said second retainer, each hook having a slit and a configuration permitting wrapping of said elastic band onto said hook, thereby altering the effective length of said elastic band, and
- an elongate lacing needle having means for selectively coupling said lacing needle to a connector member of a retainer.
