Definitions

  • the invention relates to binding devices for perforated sheets, in particular for sheets coming from a computer.
  • binding devices comprising, on the one hand, two flexible pins of high tensile plastic material, one end of which is tapered, while the other has an overhanging head, which passes through the homologous perforations of each sheet respectively in the vicinity of each end of one of its edges with the interposition of a suitable cover, on the other hand, a retaining strip plastic material in the form of a flattened "C” gutter having at each of its ends a plurality of openings, one of which is crossed by the tapered end of one of the pins, the back of the gutter being applied to the last connected sheet, and finally, on the side opposite the back, two slides each having two laterally two heels slidably engaged under the edges opposite the strip which thus forms a slide for said slides whose heels are joined by a central part in the form of a bridge under which are engaged, without play, respectively the free ends of the pins for blocking after tightening the bundle of sheets between the head of the
  • the object of the invention is to avoid these drawbacks while retaining the advantages of cost price and simplicity of manufacture described above.
  • each of its ends carries on the face opposite the back, a thin metal plate slidably engaged under the edges forming a slide, said plate having an openwork with sharp edges of diameter very close to the diameter of section of the pins and which is, after being placed in coincidence with the suitable openwork of the strip crossed by the corresponding pin.
  • l denotes the suspension strip which has in section a general shape of a flattened "C", the middle branch of which carries it at each end with a series of oblong openings 4 intended to be crossed by a flexible plastic pin 3 which comprises, on the one hand, a large projecting head 3a and, at the opposite end, an end part which is tapered 3b so as to facilitate its penetration through the openings such as 5 of the sheets to be bound 6.
  • the middle branch 1a of the strip has a face Ib which constitutes its back and a face opposite it and which is oriented towards the inside of the "C".
  • the strip On either side of said middle branch, the strip has two longitudinal wings ld straightened square, extended by the opposite edges the end portions 1f of which are, in the example, folded down towards the face lc of so as to constitute with it a slide for the lateral heels 2a of the slider 2 substantially in the shape of an "Omega", the central part 2b connected to the heels 2a by the edges at right angles 2d, constitute a bridge which can be slid over the free end of the middle part of the spindle 3.
  • edges 2d which are presented transversely to the longitudinal face the of the strip constitute, in cooperation with the end parts If, opposite, of the latter , longitudinal guide elements for the slides which, after the positioning of the pins through the openings 5 of the sheets and of the cover are slid over the said pins (FIG. 3) on which they exert a compression intended to wedge the latter in the openings 4, so as to avoid their sliding through the latter, sliding which, obviously, would determine the loosening of the bundle of sheets 6.
  • a metal plate 8 preferably made of steel and which has an aperture 7 of diameter very close to the diameter of the section right of the pins 3, the aperture being produced for example by punching, so that at least its edge 7a of the same orientation as the face lc, is in the form of a sharp edge; in particular, when the aperture 7 is produced by a punching operation, one will choose, to constitute the edge 7a, the side of the plate which carries the unblocking burrs, inevitable during such an operation.
  • the plate has a width such that it can slide under the longitudinal edges 1f of the strip so as to be retained by them when the slide is not plumb. It can thus be brought opposite that of the openings 4 which is chosen taking into account the spacing of the perforations of the sheets to be connected.
  • FIGS. 2 and 3 represent only a few sheets held between the head 3a of the spindle and the head 1b of the strip
  • FIG. 5 shows, although schematically, a device complete binding according to the invention in which we recognize the strip 1, its slide 2, the pins 3 which pass through their suitable perforations the bundle of sheets 6.
  • two covers 10, 11 have been interposed respectively between the strip 1 and the top sheet of the bundle and between the head 3a of the pins and the bottom sheet of said bundle so as to constitute, according to use, a binding capable of effectively protecting the sheets it contains.
