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.
Claims18
A multiple-use tie strip, 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 spaced curved or chevron rungs which define between them similarly shaped apertures,
- wherein the tie strip is constructed such that a front end of the tie strip can pass through one of said apertures in a first forward direction and form a closed loop, but when pulled in a second reverse direction, at least two of the plurality of rungs form a boundary around said one aperture and engage to form a co-operative latch and thereby prevent withdrawal,
- wherein each of the plurality of rungs has a central part with an apex and side arms defining a basal portion that forms a rotation joint where each rung meets the side rails, and wherein the side arms are inclined at least longitudinally towards a rear end of the tie strip and vertically to create a double rake angle of each rung that points both backwardly and upwardly.
