Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
64 words
Protection equipment for a plurality of flexible elongated members, comprising a link having a support component adapted to be pivotally connected adjacent its ends to two other support components of adjacent links, respectively, and two retaining components securable to opposed sides of the support component, respectively, to define two closed-sided passages extendable around the flexible elongated members which in use pass through the passages.
Claim 2
Dependent Claim
64 words
Protection equipment for a plurality of flexible elongated members, comprising a link having a support component adapted to be pivotally connected adjacent its ends to two other support components of adjacent links, respectively, and two retaining components securable to opposed sides of the support component, respectively, to define two closed-sided passages extendable around the flexible elongated members which in use pass through the passages.
Claim 3
Dependent Claim
29 words
Equipment as claimed in claim 1, in which the retaining component comprises a U-shaped element the ends of the limbs of which are releasably securable to the support component.
Claim 4
Dependent Claim
59 words
Equipment as claimed in claim 2, in which at least one end of the U-shaped element defines a bore, and in which at least one lug is provided on the support component, the lug defining a bore, a pin being locatable in said bores to retain said at least one end of the U-shaped element to the support component.
Claim 5
Dependent Claim
69 words
A chain for protecting a plurality of flexible elongated members, comprising a plurality of links, each link having a support component adapted to be pivotally connected adjacent its ends to two other support components of adjacent links, respectively, and two retaining components securable to opposed sides of the support component, respectively, to define two closed-sided passages extendable around the flexible elongated members which in use pass through the passages.
