Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A combination of inter-connecting extruded members comprising: short lengths of connecting members each having a hollow interior, a periphery which is substantially circular in cross-section and a plurality of integral connecting means formed on said periphery; an engaging member having engaging means; each connecting means comprising a locking groove running lengthwise along said connecting member, and each engaging means comprising a locking tongue running lengthwise along said engaging member, said groove and tongue inter-locking to prevent withdrawal except by sliding said members relative to each other in a direction parallel to their lengths; and an extruded elongate intermediate member passing through the hollows of each of the lengths of connecting member and on which said lengths of connecting member are mounted, said engaging member inter-connecting with each of the lengths of connecting member, said intermediate member having a hollow interior provided with at least one securing portion, each securing portion comprising two projecting lips extending from the interior of the hollow of the intermediate member along the length of the intermediate member and which is circular in cross section over at least a major part of its circumference.
Claim 2
Dependent Claim
188 words
A combination of inter-connecting extruded members comprising: short lengths of connecting members each having a hollow interior, a periphery which is substantially circular in cross-section and a plurality of integral connecting means formed on said periphery; an engaging member having engaging means; each connecting means comprising a locking groove running lengthwise along said connecting member, and each engaging means comprising a locking tongue running lengthwise along said engaging member, said groove and tongue inter-locking to prevent withdrawal except by sliding said members relative to each other in a direction parallel to their lengths; and an extruded elongate intermediate member passing through the hollows of each of the lengths of connecting member and on which said lengths of connecting member are mounted, said engaging member inter-connecting with each of the lengths of connecting member, said intermediate member having a hollow interior provided with at least one securing portion, each securing portion comprising two projecting lips extending from the interior of the hollow of the intermediate member along the length of the intermediate member and which is circular in cross section over at least a major part of its circumference.
Claim 3
Dependent Claim
132 words
A combination of inter-connecting extruded members comprising: a connecting member having a periphery which is substantially circular in cross section and a plurality of integral locking grooves about and formed on said periphery, grooves running lengthwise along said connecting member; and an engaging member having two locking tongues running lengthwise along the engaging member and interlocking with two of said locking grooves to prevent withdrawal except by sliding said members relative to each other in a direction parallel to their lengths, said engaging member being substantially channel shaped having a base and two projecting and inwardly converging walls which do not touch, the walls having the locking tongues at their free ends, and a pair of projecting lips on the interior of said base defining a captive groove receiving an electrical cable.
Claim 4
Dependent Claim
132 words
A combination of inter-connecting extruded members comprising: a connecting member having a periphery which is substantially circular in cross section and a plurality of integral locking grooves about and formed on said periphery, grooves running lengthwise along said connecting member; and an engaging member having two locking tongues running lengthwise along the engaging member and interlocking with two of said locking grooves to prevent withdrawal except by sliding said members relative to each other in a direction parallel to their lengths, said engaging member being substantially channel shaped having a base and two projecting and inwardly converging walls which do not touch, the walls having the locking tongues at their free ends, and a pair of projecting lips on the interior of said base defining a captive groove receiving an electrical cable.
Claim 5
Dependent Claim
15 words
A combination as claimed in claim 2 wherein said connecting member has a hollow interior.
Claim 6
Dependent Claim
13 words
A combination as claimed in claim 3 wherein said hollow interior is threaded.
Claim 7
Dependent Claim
71 words
A combination as claimed in claim 4 wherein a male threaded member which screws into the hollow interior has a threaded hole passing though it in an axial direction, and the combination includes a threaded shaft which screws into the threaded hole, the shaft bearing a pressure pad at an end, the constructions and arrangement being such that the distance between the pressure pad and the connecting member can be varied.
Claim 8
Dependent Claim
31 words
A combination as claimed in claim 2 wherein the base of the substantially channel shaped engaging member is provided with an outwardly opening dovetail slot running lengthwise along the engaging member.
Claim 9
Dependent Claim
36 words
A combination as claimed in claim 2 wherein the walls of the substantially channel shaped engaging member have side portions extending at right angles from the base before converging, the side portions having apertures in them.
Claim 10
Dependent Claim
70 words
A combination as claimed in claim 2 wherein said engaging member is provided with said locking tongues at only intervals along its length and wherein the connecting member is provided with said locking grooves along only a portion of its length, the construction and arrangement being such that the two members can be engaged or disengaged by relative lengthwise or axial sliding movement over only a portion of their lengths.
