Abstract
A file (100), provided with at least a front cover (2), a back cover (3), a spine (4) and at least one arch for fastening paper and the like, wherein the front cover (2), the back cover (3) and the spine (4) are manufactured in one piece, preferably by injection molding from plastic, hinges (5, 6) being co-formed for connecting the covers with the spine (4), coupling means being provided for fastening the or each arch to one of the covers (3,4) or the spine (4).
Claims16
A file comprising:
- a cover provided with at least a front cover portion, a back cover portion, a spine and coupling means provided on one of the cover portions or the spine for fastening an arch to the cover after it has been injection molded, said coupling means being co-injection molded in the file, wherein the front cover, the back cover and the spine are manufactured in one piece from plastic, and include hinges being co-formed therebetween for connecting the covers with the spine, and wherein the coupling means comprise clamping means, with which the arch can be fixed to the cover, said clamping means including a flange spaced from one of the cover portions and/or the spine and a recess formed in said flange;
- and
- an arch coupled to said coupling means for fastening paper in said cover, said arch including a substantially planar base plate having an edge and at least one leg extending upwardly from said base plate, said base plate edge being retained under said clamping means flange and said upwardly extending leg being received in said flange recess, wherein said arch is snap-fit coupled to said coupling means without having to fold over any part of said coupling means to establish said snap-fit coupling between said arch and said coupling means.
In combination:
- a set of plastic covers, each cover comprising at least a front cover portion, a back cover portion and a spine interconnected by hinges, wherein first coupling means are integrally molded in the cover, said first coupling means including clamping means having a flange spaced from the cover and a recess formed in the flange;
- and
- a set of metallic arches for clamping paper, each arch being provided with second coupling means cooperating with the first coupling means for selective coupling of said arches to said covers, said second coupling means comprising a substantially planar base plate having an edge and at least one leg extending upwardly from said base plate, said base plate edge being retained under said clamping means flange and said upwardly extending leg being received in said flange recess upon coupling of said arch to said cover, wherein said arch is snap-fit coupled to said first coupling means without having to fold over any part of said first coupling means to establish said snap-fit coupling between said arch and said first coupling means.
A method for presenting files comprising the steps of:
- providing plastic covers, each cover comprising a front cover portion, a back cover portion and a spine interconnected by hinges, which covers are integrally molded with first coupling means comprising clamping means, said clamping means including a flange spaced from the cover and a recess formed in said flange;
- and
- providing metallic arches adapted to fix paper, said arches including second coupling means cooperating with the first coupling means for selective coupling of said arches to said covers, said second coupling means comprising a substantially planar base plate having an edge and at least one leg extending upwardly from said base plate, said base plate edge being retained under said clamping means flange and said upwardly extending leg being received in said flange recess, upon coupling of said arch to said cover,
- wherein the covers and arches are provided apart from each other, such that a cover and at least one arch can be combined to a file directly before use, and wherein said arch is snap-fit coupled to said first coupling means without having to fold over any part of said first coupling means to establish said snap-fit coupling between said arch and said first coupling means.
