Abstract
Abstract A tarpaulin or other similar protective cover of flexible sheet material is adapted to be tied down securely with the aid of a single tie-down line extending around its periphery. The periphery is edge-finished with a continuous hollow conduit laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into the hollow conduit. Each cut-out defines a hole in the conduit wall which, in use of the tarpaulin with a tie-down line loosely contained in, and longer than, the conduit, permits a length portion of the line to be pulled outwardly from the conduit in a looped configuration for anchoring attachment to a respective tie-down device. Tearing of the tarpaulin by anchoring forces exerted thereon by way of the single tie-down line is effectively resisted, notwithstanding the absence of grommets or other relatively expensive reinforcement measures.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A tarpaulin or other similar protective cover of flexible sheet material, wherein the periphery of the tarpaulin is uniformly edge-finished with a continuous hollow conduit, said edge-finished periphery being laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into said hollow conduit, each cut-out defining in the conduit wall a hole whose diameter is substantially exceeded by each of said equally spaced intervals; and wherein means for anchoring said tarpaulin to external tie-down devices are provided at the periphery of said tarpaulin, said means comprising a tie-down line loosely contained, and freely movable, within said continuous hollow circuit, said tie-down line having a length sufficiently exceeding that of said conduit to permit concomitant withdrawal from said conduit through said holes of respective length portions of said tie-down line in looped configurations for anchoring attachment to respective ones of said external tie-down devices.
Claim 2
Dependent Claim
144 words
A tarpaulin or other similar protective cover of flexible sheet material, wherein the periphery of the tarpaulin is uniformly edge-finished with a continuous hollow conduit, said edge-finished periphery being laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into said hollow conduit, each cut-out defining in the conduit wall a hole whose diameter is substantially exceeded by each of said equally spaced intervals; and wherein means for anchoring said tarpaulin to external tie-down devices are provided at the periphery of said tarpaulin, said means comprising a tie-down line loosely contained, and freely movable, within said continuous hollow circuit, said tie-down line having a length sufficiently exceeding that of said conduit to permit concomitant withdrawal from said conduit through said holes of respective length portions of said tie-down line in looped configurations for anchoring attachment to respective ones of said external tie-down devices.
Claim 3
Dependent Claim
40 words
A tarpaulin or other similar protective cover of flexible sheet material according to claim 1, wherein said continuous hollow conduit, with which the periphery of the tarpaulin is uniformly edge-finished, is incorporated in a frill made integral with said tarpaulin.
Claim 4
Dependent Claim
38 words
A tarpaulin or other similar protective cover of flexible sheet material according to claim 1, wherein said continuous hollow conduit, with which the periphery of the tarpaulin is uniformly edge-finished, is incorporated in a hem of said tarpaulin.
