Definitions

  • the invention relates to a metal-free file connector made of plastic for stringing and releasably connecting perforated documents, with two retaining strips, in which spherical extensions alternate with web-like parts in the manner of a string of pearls, and with a clamping web with clamping bumps for lateral clamping of each through a hole in the clamping web guided and laterally folded holding strips, each clamping hump having a longitudinal slot open at the top for receiving a web-like part of the respective ball strand of the holding strip.
  • Such file connectors are already known. They serve to releasably combine punched documents into a more or less thick stack for archiving or other storage.
  • Some known file connectors are made of metal, and the holding strips are designed as bendable, unfortunately sharp-edged metal strips with a width that is slightly smaller than the diameter of the stitching holes.
  • the two stitching holes that are made with the usual stitching holes all have the same diameter of 5 mm and a distance of 8 cm).
  • the holding strips of these known metal file connectors represent the two-sided extension of the likewise metallic base web in the non-bent state, which can also be widened compared to the holding strips.
  • the clamping web made of metal or plastic, consists of a strip with two holes rounded on both sides. More demanding versions contain sliding clamping tabs for the bent holding strips.
  • Another file connector made of plastic has become known and is also located on the Market.
  • the clamping web has a gripper on the outside next to each hole, under which the holding strip bent outwards can be clamped horizontally, ie sideways.
  • This known file connector requires a special tool consisting of two parallel, thin-walled tubes connected by a web, onto which the documents to be filed are first pushed. Then the holding strips mentioned are inserted into the tubes and the stack of documents is transferred from the tubes to the holding strips. Even if this tool is not absolutely necessary, filing single sheets is difficult due to the relatively narrow and sharp-edged holding strips.
  • DE-A1-1 436 207 discloses a stapling device for perforated sheet documents according to the preamble of the present patent claim 1.
  • the perforated sheet documents are connected to one another by two generic, but unconnected, holding strips which pass through the stitching holes and then up and down be fixed by means of a support plate.
  • a disadvantage of this solution is in particular the requirement of two support plates, therefore a loose, easily slipping from the hands and difficult to control, as well as a construction of the support plates, which does not allow reliable fixing of the holding strips ("pearl rods").
  • the object of the invention is to provide a file connector which does not have the disadvantages described and in particular is metal-free, since metal strips are firstly sharp-edged and damage the stitching holes, secondly cause rust stains on the documents, thirdly metal-containing file connectors are not solvent-resistant and fourthly catch high-frequency drying of the stack of documents after deacidification (see below).
  • the file connector according to the invention forms the subject of independent claim 1, while special embodiments are defined in the dependent claims.
  • the archivists are afraid of losing the written and printed cultural assets of the past 150 years (i.e. since the production of the industrially manufactured alum paper). Work is being carried out feverishly on a system which is to make it possible to treat relatively large throughputs of books and documents at low cost in such a way that cellulose decay is at least slowed down by the acid ions if it cannot be stopped.
  • the aim is to send the stored documents in packages through a system in which the documents are treated with chemicals and solvents, some of which are gaseous.
  • the file connector according to the invention must consist entirely of plastic, specifically of a plastic that can withstand the chemicals to be used in the deacidification, does not absorb anything and does not itself release anything.
  • the file connector which can be produced with its two parts in one tool by injection molding, preferably consists of a plastic which is thermoplastic but contains elastomer parts. Not particularly preferred is a mixture of thermoplastic and elastomeric plastics, but block copolymers with hard, crystalline segments made of polyalkylene terephthalates and soft, amorphous segments based on long-chain polyether glycols.
  • plastics e.g. the Hytrel types (Du Pont) are characterized by solvent resistance, high toughness and springback, high flexural strength and good flexibility; the surface is smooth and reminiscent of polytetrafluoroethylene.
  • the plastics are resistant to aging and should not become brittle; this property is important for long-term retention of documents.
  • Plastics of type HYTREL® 7248 are preferred.
  • the file connector initially has a base web 10 on which two are spaced apart by 80 mm Holding strips 12, 14 are molded.
  • the holding strips have a cylindrical, approx. 15 to 40 mm long lower length 13, 15 with a diameter of approx. 4.5 mm.
  • This is followed by a ball strand 16, 17, which is approximately 50-100 mm long.
  • the diameter of the spherical extension is at most equal to that of the stitching holes (5 mm).
  • the clamping web 18 has two clamping or holding bumps 20, which have a circular passage 21 and a longitudinal slot 22 made on the top.
  • the distance d of the balls in the ball strands 16 and 17 corresponds to the length of the longitudinal slots 22 such that one ball lies against the holding bump 20 at the front and the next ball with slight axial tension on the rear side of the same holding bump when the ball strand 16 or 17 passes through the longitudinal slot 22 is pulled or pressed into the passage 21, see FIG. 2.
  • the clamping hump 20 is preferably provided with a front, partially spherical recess 23 into which the corresponding ball of the spherical strand 16, 17 can be inserted.
  • the holding bumps 20 are not insulated on the clamping web 18, but are formed on reinforcing ribs 26, 28 on the longitudinal edges of the clamping web 18. This significantly improves the stability of the clamping web.
  • Each of the two holes 19 in the clamping web 18 is provided on the outside, ie toward the clamping hump 20, with a semicircular and slot-shaped recess 24 into which a web but not a ball of the ball strands 16, 17 fits.
  • a ball lies under tension on the one hand on the circumference of the recess 24 and on the other hand on the adjacent end surface of the retaining bump.
  • the above-mentioned distance of the holding strips (80 mm) is not provided between the centers of the holes 19, but between the centers of the recesses 24.
  • the longitudinal slot 22 has a width, i.e. Opening that is a little smaller than the thickness of one of the webs mentioned. The holding strip is therefore reliably clamped.
  • Figure 4 now shows a variant of the file connector according to the invention, which enables punched files from a stack 29, e.g. to transfer a folder 30 with two upright pins 32 slightly bent at the top, quickly and easily onto the file connector according to the invention.
  • the foremost pearl of both spherical strands 16, 17 (FIG. 1) is replaced by a sleeve 34, the inside diameter (e.g. 4.2 mm) of which fits on the pins 32; the length of the cavity of the sleeve is e.g. 8-12 mm.
  • the file connector as shown in FIG. 4, is plugged onto the pins 32. After transfer of the stack 29 to the holding strips 12, 14, the sleeve 34 is pulled off, and the clamping web can be put on.
  • the documents to be filed are guided with their stitching holes up to descenders 13, 15.
  • the clamping web 18 is placed so that the upper sections of the spherical strands 16, 17 project beyond it. These are then pressed into the longitudinal slots 22 of the holding bumps 20 under tension until they are held in the passage 21. It should be noted that this clamping is done by an approximate vertical movement and that clamping and releasing is therefore easier and is effected faster than with the known file connectors.
  • the ball strands 16, 17 can have, for example, 6 to 15 balls.
  • the holding bumps 20 can also have spherical shell-shaped recesses (such as 23) at both ends of the passage 21 for better contact with the spherical extensions.
