Cable harness

Claim 2

A cable harness comprising: a flexible strap having a ratchet lock and a plurality of ratchet engaging members disposed thereon so as to define therebetween operative strap lengths corresponding to different workpiece bundle sizes, said ratchet lock having a channel orientated in the longitudinal direction of said flexible strap and sized to permit the passage of said flexible strap therethrough in said longitudinal direction only, said channel having a plurality of ratchet teeth disposed therein to engage said ratchet engaging members on said flexible strap when in operation, said flexible strap is moved through said channel to tighten said cable harness about a bundle and to restrain, by virtue of that engagement, the movement of said flexible strap in a cable harness loosening direction while permitting movement in the tightening direction, thereby locking said cable harness, and a ratchet lock lateral opening means serving to open a side of said ratchet lock channel so as to enable a flexible strap of a locked cable harness to be removed from the ratchet lock of said cable harness laterally with respect to the path travelled by said flexible strap through said ratchet lock, said opening means comprising a side wall or tab extending at least partially across said ratchet lock channel side.

Claim 3

The cable harness of claim 1, wherein said flexible strap has a loop shape and said ratchet lock is joined to said flexible strap at an end thereof, said joining being on the surface of said ratchet lock which is radially innermost with respect to the enclosure defined by the loop shape of said flexible strap, whereby when in operation said flexible strap is moved through said ratchet lock channel to tighten said harness about a bundle, any portions of said flexible strap passing entirely through said channel do so externally to the strap enclosure.

Claim 4

The cable harness of claim 2, further including a means for attaching said cable harness to another object, whereby said cable harness may be used to retain a bundle in a fixed location.

Claim 5

A cable harness comprising: a loop shaped flexible strap having a ratchet lock on one end thereof and a plurality of ratchet flaps spaced along the surface of said flexible strap which is radially outward with respect to the enclosure defined by said flexible strap so as to define between said ratchet lock and said ratchet flaps a plurality of operative strap lengths corresponding to different enclosure sizes, said ratchet lock having a channel therethrough orientated in the longitudinal direction of said flexible strap, said channel being sized to permit said flexible strap to pass therethrough and having a plurality of ratchet teeth disposed on the interior surface thereof which is radially distal with respect to the flexible strap enclosure orientated for interlocking ratchet engagement with said ratchet flaps, said channel having a radial dimension which is slightly less than the ratchet flaps on said flexible strap required for free clearance through said channel thereby urging said ratchet flaps into ratchet locking engagement with said ratchet teeth when said flexible strap is moved through said channel, said ratchet lock having a lateral surface divided by a slot extending the length of the channel in said ratchet lock and dividing said lateral surface into a radially inner lateral surface and a radially outer lateral surface which surfaces are radially moveable with respect to each other, said slot having a normal width over at least part of its length which is insufficient to permit the passage of said flexible strap laterally from said channel.

Claim 6

A cable harness comprising: a loop shaped flexible strap having a ratchet lock on one end thereof and a plurality of ratchet flaps spaced along the surface of said flexible strap which is radially outward with respect to the enclosure defined by said flexible strap so as to define between said ratchet lock and said ratchet flaps a plurality of operative strap lengths corresponding to different enclosure sizes, said ratchet lock having a channel therethrough orientated in the longitudinal direction of said flexible strap, said channel being sized to permit said flexible strap to pass therethrough and having a plurality of ratchet teeth disposed on the interior surface thereof which is radially distal with respect to the flexible strap enclosure orientated for interlocking ratchet engagement with said ratchet flaps, said channel having a radial dimension which is slightly less than the ratchet flaps on said flexible strap required for free clearance through said channel thereby urging said ratchet flaps into ratchet locking engagement with said ratchet teeth when said flexible strap is moved through said channel, said ratchet lock having a lateral surface divided by a slot extending the length of the channel in said ratchet lock and dividing said lateral surface into a radially inner lateral surface and a radially outer lateral surface which surfaces are radially moveable with respect to each other, said slot having a normal width over at least part of its length which is insufficient to permit the passage of said flexible strap laterally from said channel.

Claim 7

The cable harness of claim 4, wherein the distance between the first ratchet tooth and the last ratchet tooth engaged by a ratchet flap passing through said channel is not less than the distance between each of the ratchet flaps on said flexible strap, whereby when in operation said flexible strap is moved through said ratchet lock channel to tighten said cable harness about a bundle, as a leading ratchet flap disengages from the last ratchet tooth in said channel the following ratchet flap will already be in engagement with the ratchet teeth in said channel, thereby preventing any cable harness loosening backwards movement of said flexible strap.

Claim 8

The cable harness of claim 5, wherein said flexible strap has a substantially annular shape and is joined to said ratchet lock at the surface thereof, which is radially innermost with respect to the enclosure defined by said flexible strap, whereby when in operation said flexible strap is moved through said ratchet lock channel to tighten said cable harness about a bundle any portions of said flexible strap passing entirely through said channel do so externally to the strap enclosure.

Claim 9

The cable harness of claim 6, further including at least one grippable projection extending from the radially inner and/or outer lateral surfaces of said ratchet lock for use in effecting the radial movement of said inner and outer lateral surfaces with respect to each other, whereby the slot therebetween can be widened to enable the passage of the flexible strap laterally from said ratchet lock to unlock the cable harness.

Claim 10

The cable harness of claim 6, further including a means for attaching said cable harness to another object, whereby said cable harness may be used to retain a bundle in a fixed location.

Claim 11

The cable harness of claim 8, wherein the means for attaching said cable harness to another object is affixed to said cable harness on the radially outermost surface of the ratchet lock and further including a grippable projection extending from the radially inner lateral surface of said ratchet lock for use in effecting the radial movement of the inner and outer lateral surfaces with respect to each other, whereby said slot between said inner and outer surfaces can be widened to enable the passage of the flexible strap laterally from the channel when the cable harness is unlocked.
