CABLE TIE

Abstract

A cable tie has a head piece and a strap, which can be pushed into the head piece, thereby fixing itself in a latching manner, wherein a wedge-shaped compensation piece, which can be positioned in the region of the head piece, is threaded onto the strap in order to bound a hollow space together with the strap.

Claims

1. A cable tie having a head piece and a strap, which can be pushed into the head piece, thereby fixing itself in a latching manner, wherein a compensation piece (5, 7, 25, 44), which can be positioned in the region of the head piece (4, 8), is threaded onto the strap (6, 9) in order to bound a hollow space together with the strap, wherein the compensation piece (5, 7, 25, 44) has a wedge-shaped cross section in the plane of the perimeter of the hollow space (15), with two long arms (33, 34) and a short base (35), and a surface, which forms a long arm (33) is designed planar as an abutment for the head piece (8).

Description

[0034] Different design variants of cable ties and compensation pieces are shown in the drawings and are explained in more detail below. Shown are:

[0035] FIG. 1 a schematic representation of a section through a known cable tie,

[0036] FIG. 2 a perspective view of a cable tie with compensation piece,

[0037] FIG. 3 a section through a cable tie with a compensation piece,

[0038] FIG. 4 a first perspective view of the cable tie shown in FIG. 3,

[0039] FIG. 5 a second perspective view of the cable tie shown in FIG. 3,

[0040] FIG. 6 the compensation piece as shown in FIG. 3 as a detail,

[0041] FIG. 7 a partial section of a cable tie with a compensation piece, which has a flexible contact surface,

[0042] FIG. 8 a front view shown in FIG. 7 on the compensation piece,

[0043] FIG. 9 a rear view of the compensation piece shown in FIG. 7,

[0044] FIG. 10 a side view of the compensation piece shown in FIG. 7,

[0045] FIG. 11 a plan view of the compensation piece shown in FIG. 7,

[0046] FIG. 12 a view of a section through the compensation piece shown in FIG. 7,

[0047] FIG. 13 a perspective view of a compensation piece according to FIG. 7 with an implied elastic support, and

[0048] FIG. 14 a compensation piece as shown in FIG. 7 with an implied printable plate.

[0049] The cable tie 1 shown in FIG. 1 consists of a head piece 2 and a strap 3.

[0050] In the exemplary embodiment shown in FIG. 2, a compensation piece 5 is in contact with the head piece 4 and the strap 6 has been pulled through the compensation piece 5 and the head piece 4. A similar design is shown by the exemplary embodiment according to FIG. 3. Here, the compensation piece 7 is in contact with the head piece 8 and the strap 9 has been threaded through an opening 10 in the compensation piece 7 and through the head piece 8. A set of teeth 11 on the head piece 8 interacts with a set of teeth 12 on the strap 9 in order to hold the end 13 of the strap 9 in the head 8.

[0051] In addition, the edge 14 on the compensation piece 7 can interact with the teeth 12 on the strap 9. However, this is not necessary for the functioning of the invention.

[0052] In the exemplary embodiment shown in FIG. 3, the hollow space 15 bounded by the strap 9 is circular with a diameter 16 of ? inch. In a matching manner to this exemplary embodiment, FIG. 6 shows the compensation piece 7 with a concave or convex outer contact surface 17 on the opening 10, with a radius 18 of, for example, 10.7 cm. The opposite surface 19 is designed concave with a radius 20 of, for example, 7.0 cm. The contact surface 21 facing the hollow space 15 has a length 22 of 4.6 mm and a radius 23 of 8.3 cm. As the shoulder 24, on both sides of the contact surface 21 a height of 0.5 mm is provided.

[0053] FIG. 7 shows the interaction of the head piece 8 and the strap 9 with a compensation piece 25, which has a flexible contact surface 26, which is preferably elastic. The flexibility ensures a planar contact, for example with a piece of hose (not shown) arranged in the hollow space 15 and an elasticity compensates for any reduction in the contact pressure due to an elongation of the strap 9 or a shrinking of the hose piece.

[0054] An enlarged labelling area 27 and an additional contact surface 28 of the compensation piece 25 on the head piece 8 is obtained by the projection 29 on the compensation piece 25.

[0055] Cumulatively or as an alternative to the flexible surface 26, in the region 30 between the compensation piece 7 and the head piece 8 or in the region of the surface 19 between the compensation piece 7 and the strap 9, a flexible and preferably elastic surface (not shown) can also be provided, in order to exert adequate long-lasting pressure on the component (not shown) surrounded by the cable tie.

[0056] These flexible contact surfaces can also be designed as a shoulder.

[0057] The compensation piece 25 can have, for example, a height 31 of 3.5 mm, a length 32 of 9.1 mm and a width B of 7 mm. The wedge-shaped cross section is formed by two long arms 33, 34 and a short base 35.

[0058] Each of the junctions 36 from the long arm 33 to the short base 34 and that 37 between the long arm 34 to the short base 35 is rounded off. The contact surface 30 of the long arm 33 for the contact with the head piece 8, on the other hand, is flat.

[0059] As a through passage 10 for the strap 9, the compensation piece 25 has a slot 38, the longer side 39 of which having a width B in the exemplary embodiment of 5.5 mm matches the width 40 of the strap 9, so that the compensation piece 25 can be displaced on the strap 9 and does not slip off the strap 9.

[0060] The shorter side 41 of the slot 38 has an elastically designed contact surface, which presses against the strap 9 and thus forms a slight resistance when the compensation piece 25 is moved along the strap 9.

[0061] The edge 14 shown in FIG. 6 forms a stop 42 on a toothed outer surface 12 of the strap 9 and interacts with the strap 9 as a counterpart.

[0062] FIG. 12 shows an elastic part 43 on the compensation piece 44, which can deform under pressure and ensures a good contact of the compensation piece 44 against an object which is surrounded by the strap 9.

[0063] A compensation piece 45 with an elevation 46, implied by dotted lines, designed as a preferably elastic contact surface of the compensation piece 45 against a head 8 of the cable tie, is shown in FIG. 13.

[0064] FIG. 14 shows a compensation piece 47 with an enlarged contact surface 48 on the short base of the compensation piece. This surface is suitable for marking or affixing a label.
