Sweden-Sweden (SE) 751 ^ 322-2 (71) Produnik AB, c / o Rune Olsson, Hasselviksvägen 10, 230 12 Höllviksnäs,

The present invention relates to a device for assembling torn papers into bundles by passing a device through two holes in a paper hole, Sweden-Sweden (SE) (72) Rune Olsson, Höllviksnäs, Sweden-Sweden (SE) (74) 0y Kolster consisting of a resilient strip which, via the shoulders at the ends, joins protruding end strips parallel to the strip. Such a device is hereinafter referred to as a safety connector *

According to the invention, a safety connector of the type described has the features of claim 1. Thus, it is possible to place torn papers fastened together by a safety connector in covers provided with a fork mechanism, etc., te. for all exposed lids where the distance between the holes is in accordance with the SIS standard.

The safety connector can alternatively be designed for use in the two upper or lower holes of the torn papers. It can be made of plastic in different colors.

Two embodiments of the invention are explained below with reference to the drawing.

Fig. 1 is a plan view of a safety connector according to the invention, which connector 2 6318 6 is intended for assembling torn document papers with four holes, whereby the backup connector is fitted in the two inner holes.

Figure 2 is a longitudinal sectional view of the safety connector.

Figure 3 is a plan view of the safety connector seen from the opposite side.

Fig. 4 is a plan view corresponding to Fig. 1 of a safety connector for fitting into two upper or lower holes in four-hole torn papers.

Figures 3-8 are views similar to those in Figures 1-4 and show an embodiment in which the safety connector is molded. In addition, it should be noted that in said embodiment, the end strips run in the longitudinal direction of the strip.

The security connector shown comprises a strip 10 of resilient plastic material so that the strip can be bent from its uniform shape shown and then returned to this uniform shape when released. The ends of the strip have strips 11 which, in the embodiment according to Figures 1-4, are stamped and bent out of the strip and which are turned in opposite directions. Due to the stamping of the strips, the strip 10 has openings 12. The strip extends over the strips by a portion 13 at both ends and, together with the adjacent strip 11, delimits a groove 14 *

The distance between the two grooves 14 at these bases is adjusted to the distance between the distal edges of the innermost holes in a standard type four-hole perforation, i.e. this distance is 75 »5» a * When the safety connector strips 11 are inserted into the holes, the spaced apart edges into the grooves 14 «so that a plurality of torn papers secured together by a safety connector according to the invention remain properly together in the groove 14 between each strip 11 and the protrusion 13. However, the maximum distance between both inner fork brackets and since the maximum distance between the openings 12, i.e. from the spaced-apart edges of the openings, those edges closest to the projections 13, is 74 nm in the safety connector according to the invention, the fork mechanism can be passed through the openings 12 of the safety connector when the muesli connector is attached to the torn paper stack. This is a substantial advantage, as the papers can also be assembled with a safety connector on the covers, whereby the safety connector not only reinforces the holes in the papers.

Claims (3)

3 63186 The safety connector of Figure 4 is similar in embodiment to that of Figures 1-3, but is shorter to be inserted into the upper or lower holes of the torn papers. Figures 3-8 are a molded safety connector made of a suitable plastic material. In this case, while maintaining the good properties of the connector according to Figures 1 to 4, it is possible to shape more precisely the transition area between the strip and the strip, which forms a abutment surface against the holes in the papers. As can be seen from the partial views shown in connection with Figures 3 and 6, said abutment surface in this case is substantially in the shape of a part of a circle. A circular abutment surface having a radius substantially equal to the radius of the holes in the papers allows the papers to be tightened with a certain force without damaging the holes. It will, of course, be appreciated that by appropriate sizing of the height of the abutment surface, i.e., the distance between the strip and the strip, these safety connectors can be made to hold and tighten the desired maximum amount of paper. A paper holder for assembling perforated sheets of paper into bundles by passing it through two holes in the sheets of paper, which holder consists of a flexible strip (10) with openings (12) for passing the forks of the fork mechanism and a strip parallel to the outer edges that the end strips (11) have shoulder portions (14) at the transition point from the edges of the openings (12) which are softly shaped to rest against the distal edges of the holes, and that the strip (10) and the end strips (11) are so flexible that the end strips can be pass the stack of paper through the holes without changing its shape. Holder according to claim 1, characterized in that the strip (10) extends over the shoulder parts (14) of the strips in the direction of the strips, bounded by sheets of paper outside the spaced-apart edge portions of the holes. Holder according to Claim 1 or 2, characterized in that it is molded in such a way that the radius and height of the shoulders (14) are determined. o '. of
