Description

Strapping device for boxes, bales or the like. The previously known Strapping devices are mostly larger or smaller machines and consist of many Parts assembled. The clamps on these machines grip the ends the strapping means and by means of levers, screw devices or the like: are now the strapping means stretched. The ends are then connected the means of strapping, again mostly with the use of devices intricate design.

In contrast, the present invention is an extremely simple strapping device, which essentially consists of a U-shaped, rigid, one-piece clamping bracket and the clamping lever combined with the clamping devices. The thighs or Arms of this U-shaped bracket have slotted mouths at the ends, which with Tensioning screws or the like are closed to each end of the strapping means to hold on. By pivoting the bracket about its central axis, the strapping means stretched, the ends of the same lying next to each other or crosswise on top of each other come so that they are connected when it is a matter of wire or, when it is used as a means of tying Band iron is chosen, laid flat on top of one another and, for example, riveted can.

The invention is shown in the drawing, namely Fig. r such a bracket with slots and clamping screws. Fig.2 shows the example Execution of the tool which is used to twist the ends of the tensioned wire should serve.

Fig. 3 and 4. are schematic representations of the operation at Tensioning the strapping means.

Fig. 5 shows the closure of a wire lacing achieved by twisting. To a box, a bale or the like. With z. B. to provide a wire lacing, the bracket a, as shown in the schematic (Fig. 3) shows, on the the object to be strapped d.

The ends of the tying means are then inserted into the slots b placed and clamped by means of the screws c.

The bracket a is then, as in Fig. Q. visible, folded, and as a result, (the strapping means is tightened.

It does not matter whether the stirrup is at the initiation of tensioning vertically, as in Fig. r, or flat, as in Fig. 3. For bracing As can be seen, a rotation of the bracket around the axis A-B is required.

The tensioned wire can now lie in the bracket, as in Fig. I or Fig. 4 shown. A slight movement of the bracket (Fig. Q.) Can be achieved that the wire end coming from the left is also under the bracket a.

Now the twisting device n (Fig. 2) with its slot e brought over the adjacent wires f, g, so that the same next to each other in the slot e.

The twisting tool is now rotated by means of a pivotable angle lever 1z, i in the direction of arrow C in a second slot which is perpendicular to the first slot.

As soon as the lever arm h reaches approximately the position k shown in dotted lines has, the angle lever is pivoted in the direction of arrow D about go °, so that the lever arm i comes into the working position, whereupon the operation in the direction arrow C follows, etc.

This creates a wire connection as shown in Fig. 5.

Now the twisting tool is lifted off the tying means, the screws c are loosened and the bracket a from the tensioned and locked Wire lifted.

By means of the bracket a, which instead of the screws c also arbitrarily known other pressure means, e.g. B. eccentric, can also except wire other tying means, e.g. B. band-shaped, are stretched.

Are these tying means so wide that they can be twisted cannot be closed with the device according to Fig.2, a connection must be made the ends are made in a known manner using buckles or rivets.

Claims (2)

PATENT CLAIMS: r. Strapping device for boxes, bales, etc. Like., characterized by a one-piece rigid bracket (a) in U-shape, whose The legs or arms have slotted mouths (b) at the ends, which have clamping screws (c) or the like are closed in order to hold one end (l, na) of the strapping means and that with the ends of the strap means captured about the central axis (A-B) _ or around one of its thighs supported on the object to be strapped (d) is rotated and thereby the strapping center ends (wire, band iron or the like.) tensioned and the tensioned wire ends placed next to each other in the bow bulge, so that they are twisted together with a wire winding device or otherwise known Way can be closed. 2. Wire winding device for the strapping device according to claim r, characterized by a longitudinally slotted cylinder (s), in whose longitudinal slot (e) the wires to be twisted (f, g) are inserted and which by an angle lever (la, i), which in a second, perpendicular to the first longitudinal slot of the cylinder (n) is rotatably mounted about a pin, is driven in such a way that the angle lever (h, i) is alternately pivoted around the pin in such a position that always one of its Legs serve as drive levers and through it the slotted cylinder (s) can be rotated each time by r80 ° around the wire axis, whereupon the other leg of the angle lever is pivoted into the working position and the cylinder (x) is rotated further by this, and so on.
