Description

30th

The invention relates to a binding device with a suspension device for one on the edge of the brother with holes provided pack of leaves, consist of a wire element at a distance and essentially running transversely Wire sections bent around a longitudinal axis and penetrating through the holes.

From the German utility model 71 40 669 a wall calendar is known in which the hanging device consists of a piece of wire separated from the binding device, which recess which area of the binding device is free, is bulged so as to form a larger opening for the hook. The binding device consists of loops that engage in slit-shaped holes in the pack of leaves.

Such a binding device with a suspension device is disadvantageous because there are several individual ones Operations must be carried out to obtain a ready-to-use fixture with a hanging facility to accomplish.

From the German utility model 17 32 042 a holding device for hangable calendars is known, in which a pack of two sheets of paper forming the calendar sheets extends from the sides over a certain one Blade section inwardly extending spirals is held together.

At the same time, the spirals overlap a holding rod that extends over the entire width of the sheet, in des- eo sen middle a retaining eyelet is formed.

This device is also relatively expensive, since several manufacturing and work steps are necessary. to close the pack of calendar sheets on the one hand with the spirals and on the other hand with the holding rod Mistake.

From British patent specification GB-PS 6 29 448 a binding device with a hanging device is known, which is similar to the one known from utility model 71 40 669. The difference to the first described consists in the fact that the wire forming the suspension device is separated into the two is inserted from the center outwardly extending spirals, is still bent downwards and something protrudes into the pack of leaves. The disadvantages of this binding device with hanger are thus similar to those described in connection with the utility model discussed above are.

The invention is based on the object of providing a binding device with a suspension device as described in the introduction to create mentioned type, in which the manufacture and use of the binding device complicates Multipartism is avoided.

The object is achieved in that the suspension device consists of a in the plane of the Blattpacks twisted arcuate wire section is formed.

Internal element and suspension element or

iangeor-

Gane are therefore in one piece and the binding of the pack of leaves can be done in the simplest way by that the wire element before twisting off the loop provided as a suspension element in the usual manner is introduced into the row of holes, whereupon the z. B. located in the respective back section of the pack of leaves Loop using a suitable tool, e.g. B. a pair of pliers, grasped and at least approximately around Is turned 90 ° in the sheet packing level. Both the manufacture of the device parts and the binding the pack of leaves by means of this device is thus considerably simplified compared to the known solutions.

In the drawing are exemplary embodiments of the invention shown; it shows

F i g. I a wire element designed as a wire screw before inserting into the leaf pack,

F i g. 2 that by means of the rotary slide according to FIG. 1 bound Leaf pack with hanging loop.

Fig. 3 is provided with hook-shaped loops Wire element, the loops being shown in their closed position (after being inserted into the leaf pack), and

FIG. 4 shows that by means of the wire element according to FIG. 3 bound pack of pages with hanging hook.

The binding device according to FIGS. 1 and 2 has a wire element 1 designed as a wire screw, the binding loops 3 of which are formed by the individual wire windings. To bind the pack of leaves 2, this wire screw 1 is screwed in the usual way into a row of holes 2a parallel to the back of the pack of leaves. In its longitudinal center, the back of the pack of leaves is provided with a recess 2b which interrupts the row of holes at this point. The turn or loop 3a of the wire screw 1 located in the area of this recess 2b is turned at least approximately into the sheet packing plane from its original plane lying approximately transversely to the screw axis; it still forms a piece with the wire element parts extending on both sides of the recess 2b. This twisted loop 3a serves as a suspension element for the pack of leaves. The insertion of the wire element 1 into the pack of leaves and the twisting off of the loop 3a can easily be carried out in directly successive operations on one and the same machine.

In the example shown in Figs. 3 and 4, this is

Wire element 11 is provided with double-wire round loops 13 bent out of the wire axis in the shape of a hook. These round loops are slightly opened during the manufacture of the wire element 11 and are only bent into the closed position shown in FIG. 3 after they have been inserted into the back of the leaf pack 12. Here, too, the pack of leaves 12 has, on both sides of a central back recess i2b, a row of holes 12c parallel to the back. in which the hook loops 13 of the wire element 11 are suspended. The loop 13a lying in the area of the recess 126 is at least approximately twisted from its original plane, which runs perpendicular to the wire axis, into the plane of the sheet packing and at the same time is bent upwards so that its hook opening is directed downwards; the one-piece loop 13a with the wire element parts engaging in the row of holes 12a on both sides of the recess 12b thus forms a hanging loop of the wire element 11 in the sheet pack. the closing of the loops 13 and. the twisting off of the loop 13a can be carried out in immediately successive operations on one and the same machine.

The embodiments described above each have only one centrally arranged suspension element. Of course, by twisting off several loops over the length of the back of the Leaf packs arranged distributed a corresponding back recess having points two or more suspension organs must be created on the wire element: this is especially true for relatively heavy packs of leaves (e.g. maps, posters, etc.) appropriate.
