Abstract

Clasp element consisting of a U-shaped retaining bar with beaded edges and connected with a file cover, of two slides, which are mounted slidably to and fro between a suspension setting and a stacking setting, are clippable from above onto the retaining bar and which are bringable into engagement by side webs with the beaded edges of the retaining bar, with hookshaped end sections and longitudinal webs which engage into the U-profile of the retaining bar for the formation of a central groove for flexible filing spikes, the ends of which are pluggable through openings of the retaining bar and in bent-over state lockable by the slides, wherein tongues forming a catching space for the filing spike are provided at the end of the slide pointing towards the middle of the bar, an end strip covering the cross-sectional profile of the retaining bar is provided at the end of the slide lying opposite the tongues, and wherein the central groove displays a ramp in the region of the catching space.

Dependent claims

In a clasp element for a loose-leaf binder which comprises a U-shaped retaining bar with beaded edges aadapted to be connected with a file cover, a slide which engages said beaded edges and is mounted to slide to and fro thereon between a filing setting and a stacking setting and has longitudinal webs which depend into the U-profile of the retaining bar to form a central groove for a flexible filing spike the end of which is adapted to be inserted through an opening in the retaining bar and to be bent over on movement of the slide, from stacking setting toward filing setting, the improvement which comprises;

tongues (51) dispersed over said beaded edges and spaced to form a catching space (48) for the filing spike (8) at the inner end of the slide (38), an end strip (56) covering the cross-sectional profile of the retaining bar (26) at the outer end of the slide (38) and, a ramp (76) in said central groove 66 sloping downwardly from the catching space (48) and away therefrom, whereby, on movement of said slide, said filing spike is engaged by the inner end of said ramp and then, on further inward movement of said slide, it is bent over and pressed down by said ramp.
