Description

Compression strips and perforation devices

technical field

This invention relates to compression strips for use in lever arch file folders, and more particularly, the present invention relates to compression strips incorporating perforators for punching holes in the paper.

Background technique

Hold down bars for securing files in file folders are known. One of the structures has a base with a pair of holes through which the ring frame of the file folder protrudes, and a pair of elastic rods held on the base and extending between the pair of holes, the base The seat is elongate and the holes are separated by a certain distance in the general longitudinal direction; an arm, which includes a part for bending the rod at a position between the two holes, said arm can bend the rod at the bending part movement between a first position and a second position in which the bending member does not bend the rod or is slightly bent; The stopper is used as a fulcrum, and under the action of the bending member, each rod can swing and bend around the fulcrum, so that the distance between the rods in the hole changes between the first distance and the second distance, and in The first spacing rod can fasten the ring frame protruding from the hole, and the second spacing is wider than the first spacing. In such a compression strip, the arm (known as a transverse button) is pivotally mounted on the base, which is pivotable about an axis which runs on the base in substantially the same direction as the longitudinal extending between the holes. The arm is preferably pivotally mounted to one of the bars for movement between first and second positions, and includes a cam surface that causes the arm to move when pressed into the space between the bars. The rods are separated from each other and thus bend them. The curved member may also include another surface which maintains the rod in a stable configuration in the curved state. Furthermore, said arm (known as a longitudinal button) can also be pivoted about an axis extending transversely to the longitudinal direction, while the bending member acts on said lever. Such a device is disclosed by EP, European Patent No. 0941870.

Other devices are for example shown in UK 1 531 891, while perforating elements are shown in UK 1 522 991 and devices with simple opening elements are shown in DE 4 238 783.

Typically, when documents are to be placed in a folder, such as the ring holder of a lever-arch ring folder, a hole punch is first used to perforate the pages. If such a device is not used, as a last resort, the sheets can be threaded on the ring by hand, but this is difficult and results in irregular perforations, making the sheets prone to tearing, and the excess paper folded in the between adjacent sheets so that the sheets cannot be stacked flat together.

Detailed ways

The pressing and perforating device is assembled on the ring frame of the lever arch ring folder, and compresses the sheets mounted on the ring frame. Perforating devices, although known in the prior art, have not heretofore been combined with hold-down strips, and perforating devices can be manufactured in a simple and cheap manner without the need for conventional punching machines before the files are loaded into the folder. A hole machine pre-punches holes in a sheet of paper. In addition, punched files can be aligned with the folder itself or with files already in the folder to ensure the punched holes are in the correct place.

Figures 1 and 7 show a conventional lever arch folder with the compression and perforation device 16 of the present invention mounted on the ring frame 2 of the folder. The compression and piercing device shown in Figure 1 has a longitudinal release arm or button arrangement 24, see Figure 2; however a different arrangement 25 as shown in Figure 8, or a transverse button arrangement as described in EP0941870 is also possible .

Figures 2 and 8 show the arrangement of the compacting and perforating device, wherein Figure 8a is a general view, Figure 8b shows a detailed view in a free position, and Figure 8c shows a detailed view in a locked position, with the rod 20 deflected. A plurality of holes 14 are provided on the handle part 8 , and the holes 14 pass through the body of the handle 8 . These eyelets 14 are spaced at a distance so as to correspond to the teeth 12 into which it can be seen that the teeth 12 are housed. The eyelets and teeth are arranged such that their respective distances correspond to the ring frame 2 on the file folder. Figure 1 shows two eyelets and teeth and Figure 7 shows three eyelets and teeth.

Figures 3 and 9 show the underside of the compacting and perforating device. Here one can see the usual rods and lugs in a compression strip, as well as some rivets 26 for holding each tooth 12 on the base 6 of the compression and perforating device.

Figures 4 and 10 show the pressing and perforating means of the handle part 8 in the open position. The teeth 12 protruding from the base 6 can be seen, as well as the eyelets 14 formed into the handle. The teeth 12 have metal sharp edges pressed and formed at their tubular upper ends. While the arrangement described above effectively perforates the paper, an alternative embodiment has teeth protruding from the handle with holes cut out in the base.

Figures 5 and 11 show exploded views of the compacting and perforating device. It can be seen that the teeth are surrounded and supported by a set of three tangs 36 made from the base 6 . Teeth 12 are held in place by rivets 26 . The tang 36 also acts as a stop, which limits the closing movement of the handle part 8 . Pairs of mounting lugs 28 are formed from the base 6 . A pair of arms 27 integrally formed with the handle part 8 has transverse projections 32 which engage holes 29 in the lugs 28 forming a hinged connection between the base 6 and the handle part 8 .

Figures 6a and 6b and Figures 12a and 12b show cross-sectional views of the compacting and perforating device in use. The sheet 4 is placed between the open handle part 8 and the base 6 on the teeth 12 . Then when the handle part 8 is closed, the teeth 12 and the eyelets 14 cooperate to perforate the paper sheet 4 under the shearing action, and the cut paper pieces 30 are left on the teeth 12 as shown in FIGS. 6b and 12b.

Other embodiments are also possible. For example, the arrangement of the teeth and eyelets could be reversed so that the teeth protrude from the handle part and the eyelets are formed in the base. The type of compression strip used may also vary. Although the device used in file folders has been described in this embodiment as having two and three ring stands, it is conceivable that the pressing and punching device used in file files could have four or more ring stands and corresponding teeth and eyelets.
