## Abstract

A high strength multiple-use cable tie (1), formed in a ladder-shaped construction comprising two substantially linear side rails (2) of generally uniform cross-section. These rails are interconnected by a plurality of closely spaced curved or chevron rungs (3) which define between them similarly shaped apertures (4). The free end (51) of the strip can readily pass through an aperture in a forward direction and form a closed loop, but when pulled in the reverse direction, the rungs engage to form a co-operative latch and thereby prevent withdrawal.

## Claims

### Claim 1

A high strength multiple-use tie, formed in a ladder-shaped construction comprising two substantially linear side rails of generally uniform cross-section, the rails being interconnected by a plurality of closely spaced curved or chevron rungs which define between them similarly shaped apertures, wherein the free end of the strip can readily pass through an aperture in a forward and form a closed loop, but when pulled in the reverse direction, the rungs engage to form a co-operative latch and thereby prevent withdrawal.

### Claim 2 (depends on 1)

A tie according to claim 1, which is formed from a polymer material.

### Claim 3 (depends on 2)

A tie according to claim 2, wherein the tie is formed from nylon.

### Claim 4 (depends on 1)

A tie according to claim 1, wherein the side rails and interconnecting runs have a cross section of approximately 0.8 mm2.

### Claim 5 (depends on 4)

A tie according to claim 4, wherein the side walls are formed with a rhomboidal cross section with side angles of approximately 5° to 10°.

### Claim 6 (depends on 1)

A tie according to claim 1, wherein the interconnecting rungs have longitudinal and vertical rakes of approximately 20° to 30°.

### Claim 7 (depends on 6)

A tie according to claim 6, wherein the rungs are tapered outwardly the centreline both laterally and vertically.

### Claim 8 (depends on 7)

A tie according to claim 7, wherein the vertical rake of the top rung is approximately 15° and the vertical rake of the bottom rung is approximately 25°.

### Claim 9 (depends on 1)

A tie according to claim 1, wherein the leading edges of the rungs are rounded.

### Claim 10 (depends on 1)

A tie according to claim 1, wherein a cutaway notch is provided on the underside of the rear portion of each rung.

### Claim 11 (depends on 1)

A tie according to claim 1, wherein each rung includes a flattened section which widens the centerline portion of the rung.

### Claim 12 (depends on 1)

A tie according to claim 1, wherein the tie has a tapered front end having a pointed tip leading to a tapered feed portion.

### Claim 13 (depends on 12)

A tie according to claim 12, wherein the front tip is provided with raised grips or knurls.
