Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
In a support for flexible conduit; a plurality of support bars carrying the flexible conduit; a link assembly fixed to each side of said support bars, each of the links therein having an opening at each end; each of said openings having an axis extending transversely of said links; a plurality of pins with each pin having an axis and extending into one of the openings of at least two links with the axes of said pins remaining fixed relative to the axes of said openings to connect two successive links together for relative pivotal movement so that the plurality of links are connected together to form a chain on each side of said support bars with the two chains carrying the support bars and the flexible conduit carried thereby; limiting means on each of said pins; and restricting means on said links for engagement with the limiting means on said pins to limit the pivotal movement between two successive links to thereby establish the minimum radius that will be formed by the chain.
Claim 2
Dependent Claim
174 words
In a support for flexible conduit; a plurality of support bars carrying the flexible conduit; a link assembly fixed to each side of said support bars, each of the links therein having an opening at each end; each of said openings having an axis extending transversely of said links; a plurality of pins with each pin having an axis and extending into one of the openings of at least two links with the axes of said pins remaining fixed relative to the axes of said openings to connect two successive links together for relative pivotal movement so that the plurality of links are connected together to form a chain on each side of said support bars with the two chains carrying the support bars and the flexible conduit carried thereby; limiting means on each of said pins; and restricting means on said links for engagement with the limiting means on said pins to limit the pivotal movement between two successive links to thereby establish the minimum radius that will be formed by the chain.
Claim 3
Dependent Claim
52 words
A support according to claim 1 wherein said limiting means on each of said pins comprises a cam face; and said restricting means in said link comprises a cam stop for engagement with the cam face on the cooperating pin to limit the pivotal movement of the link relative to the pin.
Claim 4
Dependent Claim
46 words
A support according to claim 2 wherein said cam stop on said link comprises a flat formed in the opening of said link complementary to the cam face on said pin for engagement therewith to limit the pivotal movement of the links relative to the pin.
Claim 5
Dependent Claim
61 words
A support according to claim 2 wherein said cam stop on said link limits the pivotal movement of said link relative to said pin in one direction, and said restricting means includes a second stop for engagement withe the cam face on The cooperating pin to limit the pivotal movement of the links relative to the pin in the opposite direction.
Claim 6
Dependent Claim
85 words
A support according to claim 4 wherein said stops are two flats formed in each of the openings of the links said flats being disposed at an angle to each other so that the first stop engages the cam face on the pin to limit the pivotal movement of the link relative to the pin in one direction and the second stop engages the cam face on the pin to limit the pivotal movement of the links relative to the pin in the opposite direction.
Claim 7
Dependent Claim
76 words
A support according to claim 1 wherein said restricting means comprises a projection extending from the periphery of each of the openings in said links towards the center of the opening; and said limiting means comprises a peripheral slot in each of said pins for receiving said projections, said slot being large enough to permit limited movement of said projections in said slot to thereby limit the pivotal movement of said links relative to said pin.
Claim 8
Dependent Claim
160 words
In a support for flexible conduit; a plurality of support bars carrying the flexible conduit; a chain assembly connected to each side of said support bars to carry the support bars and the flexible conduit carried thereby in a predetermined path of travel, each of said chains being formed by a plurality of links having an opening at each end; a pin connecting each of said links to the succeeding link by said opening for relative pivotal movement within prescribed limits; and limiting means operative to limit the pivotal movement between two successive links to thereby establish the minimum radius that will be formed by the chain, said limiting means comprise a projection extending inwardly from the periphery of each of said openings; and each of said pins being provided with peripheral slots for receiving said projections to permit limited movement of said projection in said slots to thereby limit the pivotal movement of said links relative to said pin.
