Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A cover, particularly for covering a guide element of predetermined cross-section, comprising a single-ply elongated channel-shaped cover element provided with a plurality of accordion pleats, each having an outer folded edge region; and shape-retaining reinforcing members of flexible but kink-resistant sheet material mounted in said edge regions of at least some of said pleats and extending across the free cross-section of said cover element, said members being formed with cut-outs adapted to matingly interengage with the guide element being covered, whereby such mating interengagement prevents said cover from accidentally lifting off the guide element.
Claim 2
Dependent Claim
94 words
A cover, particularly for covering a guide element of predetermined cross-section, comprising a single-ply elongated channel-shaped cover element provided with a plurality of accordion pleats, each having an outer folded edge region; and shape-retaining reinforcing members of flexible but kink-resistant sheet material mounted in said edge regions of at least some of said pleats and extending across the free cross-section of said cover element, said members being formed with cut-outs adapted to matingly interengage with the guide element being covered, whereby such mating interengagement prevents said cover from accidentally lifting off the guide element.
Claim 3
Dependent Claim
28 words
A cover as defined in claim 1; and further comprising additional ones of said reinforcing members mounted in the edge regions of the remaining ones of said pleats.
Claim 4
Dependent Claim
16 words
A cover as defined in claim 1, wherein said single-ply elongated element is of channel-shaped configuration.
Claim 5
Dependent Claim
35 words
A cover as defined in claim 1, wherein said single-ply elongated element is of fabric having an inner and outer side, at least one of which is provided with a coating of synthetic plastic material.
Claim 6
Dependent Claim
132 words
A channelshaped cover, particularly for covering a guide element of predetermined cross-section, comprising a single-ply elongated channel-shaped fabric cover coated with synthetic plastic material and provided with a plurality of accordion pleats each having an outer folded edge region and a seam region; and shape-retaining reinforcing members of flexible but kink-resistant sheet material mounted in at least some of said pleats and extending across the free cross-section of said cover, said members having cutouts adapted to matingly interengage with the guide element being covered and bounded by inner marginal portions facing the interior of said cover and outer marginal portions located within the confines of said edge regions, said outer marginal portions being sewn to said edge regions along the respective seam regions; and synthetic plastic sealing means sealing said seam regions.
Claim 7
Dependent Claim
132 words
A channelshaped cover, particularly for covering a guide element of predetermined cross-section, comprising a single-ply elongated channel-shaped fabric cover coated with synthetic plastic material and provided with a plurality of accordion pleats each having an outer folded edge region and a seam region; and shape-retaining reinforcing members of flexible but kink-resistant sheet material mounted in at least some of said pleats and extending across the free cross-section of said cover, said members having cutouts adapted to matingly interengage with the guide element being covered and bounded by inner marginal portions facing the interior of said cover and outer marginal portions located within the confines of said edge regions, said outer marginal portions being sewn to said edge regions along the respective seam regions; and synthetic plastic sealing means sealing said seam regions.
