Abstract
Abstract An elongated structural member adapted to many uses is made in separable, coaxially aligned sections to permit the sections to be stored in a short space. The sections are readily secured together in end to end relationship to form a strong member which may take both tension and compression.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said element, and a sleeve adjacent the juncture of each pair of adjacent sections and movable along said member from a position uncovering such juncture to a position covering such juncture for preventing relative lateral movement of the adjacent sections.
Claim 2
Dependent Claim
90 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said element, and a sleeve adjacent the juncture of each pair of adjacent sections and movable along said member from a position uncovering such juncture to a position covering such juncture for preventing relative lateral movement of the adjacent sections.
Claim 3
Dependent Claim
39 words
A member according to claim 1 wherein a sleeve is received on one end section, said tension element being connected to said sleeve, means on said one section for holding said sleeve in a position tensioning said tension element.
Claim 4
Dependent Claim
53 words
A member according to claim 1 wherein a handle is provided at one end section and connected to said tension element, said handle being swingable from a position outside said one end section to tension said tension element, to a position substantially within said end section to permit said sections to be separated.
Claim 5
Dependent Claim
22 words
A member according to claim 3 wherein said handle is formed with a portion for pivotally engaging a sidewall of said member.
Claim 6
Dependent Claim
21 words
A member according to claim 4 wherein said sidewall includes means for axially moving the point on which said handle pivots.
Claim 7
Dependent Claim
130 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said element, and elongated interengaging locking elements at the juncture of each pair of adjacent sections for preventing relative lateral movement of said adjacent sections, said locking elements comprising an elongated extension of reduced cross section in one element and a complementarily formed opening in the adjacent element, a sleeve received on one end section, said tension element being connected to said sleeve, means on said one end section for holding said sleeve in a position tensioning said tension element.
Claim 8
Dependent Claim
130 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said element, and elongated interengaging locking elements at the juncture of each pair of adjacent sections for preventing relative lateral movement of said adjacent sections, said locking elements comprising an elongated extension of reduced cross section in one element and a complementarily formed opening in the adjacent element, a sleeve received on one end section, said tension element being connected to said sleeve, means on said one end section for holding said sleeve in a position tensioning said tension element.
Claim 9
Dependent Claim
142 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said elements, elongated interengaging locking elements at the juncture of each pair of adjacent sections for preventing relative lateral movement of said adjacent sections, said locking elements comprising an elongated extension of reduced cross section in one element and a complementarily formed opening in the adjacent element, a handle provided at one end section and connected to said tension element, said handle being swingable from a position outside said one end section to tension said tension element to a position substantially within said end section to permit said sections to be separated.
Claim 10
Dependent Claim
142 words
An elongated multipart structural member comprising: a plurality of elongated sections of substantially uniform cross section adapted to be joined together coaxially in end to end relationship to form said member, an elongated tension element secured at opposite ends of said member for holding said sections together, means for tensioning said elements, elongated interengaging locking elements at the juncture of each pair of adjacent sections for preventing relative lateral movement of said adjacent sections, said locking elements comprising an elongated extension of reduced cross section in one element and a complementarily formed opening in the adjacent element, a handle provided at one end section and connected to said tension element, said handle being swingable from a position outside said one end section to tension said tension element to a position substantially within said end section to permit said sections to be separated.
Claim 11
Dependent Claim
22 words
A member according to claim 7 wherein said handle is formed with a portion for pivotally engaging a sidewall of said member.
Claim 12
Dependent Claim
21 words
A member according to claim 8 wherein said sidewall includes means for axially moving the point on which said handle pivots.
