  • Patent number: 10407226
    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.
    Type: Grant

  • Patent number: 8709568
    Abstract: A sheet of cellular tie strips, where each strip is composed of a series of unit cell portions connected end-to-end, is formed in a single molding process. Lateral webs join one or more strips side-by-side to form a sheet such that each strip can be readily separated by tearing, stamping, cutting, leaving only a very thin vestige which does not interfere with the tying of the strips in use.

  • Patent number: 7704587
    Abstract: A flexible, integrally formed tie strip for forming a loop when passed through itself comprises a plurality of identical cells formed in a strip, the cells forming generally loop-shaped enclosed apertures (10) bounded by wall portions of the cells, each aperture allowing the passage of further cells through it. The cells are further provided with one or more latching members (11) allowing passage of one cell through another in one direction but preventing passage of the cell in the reverse direction. The walls (9) bounding the apertures can be folded to a saddle shape about radial and longitudinal axes, so as to increase the width of the aperture without stretching the material of the walls, thereby facilitating the passage of a penetrating cell through the aperture of another cell. Moreover the penetrating cell is designed to fold so as to pass through still more easily. This three-dimensional deformation is promoted by a notch (15) in the rear of each aperture wall.

  • Patent number: 5799376
    Abstract: An integrally formed tie strip (10) is formed with a series of apertures (14), at respective locations that are spaced apart in succession along the strip, and is formed with a series of laterally projecting latch members (11), at respective locations that are spaced apart in succession along the strip, for resisting withdrawal from one of the said apertures after having been passed therethrough.
