Abstract
Abstract An interconnecting spacer is interposed between a pair of channel members, each having a central portion and substantially normally extending flanges. The spacer is H-shaped in cross section, having a central cross-bar and a pair of lateral side walls. The ends of the side walls and flanges of the channel members have cooperative engagement means. A plug is inserted within the cavities formed by the spacer and the channel members having a dimension such that the engagement means are placed under stress to lock the same.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
190 words
A frame assembly comprising a pair of open channel members, each having a central portion and substantially normally extending flanges along the longitudinal edges thereof, a spacer interposed between said channel members, said spacer being H-shaped in cross-section having a pair of lateral side walls and a central cross-bar, the ends of the lateral walls of said spacer and the flanges of said channel members being formed with cooperative engagement means, a removable plug inserted within each of the cavities formed by the lateral walls of said spacer, and the respective channel members, said plug comprising a body having a wedge shape cross-section, the larger base of said plug having a surface conforming to the central portion of said channel member and being provided with laterally extending shoulders, said surface being arranged so that it abuts the central portion of its associated channel member, and the laterally extending shoulders are compressively interposed between the flat central portion and the ends of the lateral walls of said spacer the body of said plug having a lateral dimension so as to place said cooperative engagement means under stress to lock the same.
Claim 2
Dependent Claim
190 words
A frame assembly comprising a pair of open channel members, each having a central portion and substantially normally extending flanges along the longitudinal edges thereof, a spacer interposed between said channel members, said spacer being H-shaped in cross-section having a pair of lateral side walls and a central cross-bar, the ends of the lateral walls of said spacer and the flanges of said channel members being formed with cooperative engagement means, a removable plug inserted within each of the cavities formed by the lateral walls of said spacer, and the respective channel members, said plug comprising a body having a wedge shape cross-section, the larger base of said plug having a surface conforming to the central portion of said channel member and being provided with laterally extending shoulders, said surface being arranged so that it abuts the central portion of its associated channel member, and the laterally extending shoulders are compressively interposed between the flat central portion and the ends of the lateral walls of said spacer the body of said plug having a lateral dimension so as to place said cooperative engagement means under stress to lock the same.
Claim 3
Dependent Claim
17 words
The assembly according to claim 1, wherein said channel members, said spacer and said inserts are elongate.
Claim 4
Dependent Claim
42 words
The assembly according to claim 1, wherein said plugs have a dimension perpendicular to the lateral so that each is compressed between the cross-bar and the channel members to have a force vector extending parallel to the lateral walls of said spacer.
Claim 5
Dependent Claim
15 words
The assembly according to claim 1, wherein said plugs are formed of solid resilient material.
Claim 6
Dependent Claim
14 words
The assembly according to claim 4, wherein said spacer is formed of rigid material.
Claim 7
Dependent Claim
25 words
The assembly according to claim 1, wherein said cooperative engagement means comprises cooperating hooks, bent from said flanges and lateral walls opposite to each other.
Claim 8
Dependent Claim
35 words
The assembly according to claim 6, wherein the ends of said lateral walls are recessed laterally inward from the outer surface thereof by an amount at least equal to the width of said lateral wall.
Claim 9
Dependent Claim
153 words
Apparatus for joining assembly having a pair of open channel members, each having a central portion and substantially normally extending flanges along the longitudinal edges thereof, having engaging means, comprising a spacer adapted to be interposed between said channel members, said spacer being H-shaped in cross-section having a pair of lateral side walls, and a central cross-bar, the ends of the lateral walls of said spacer being formed with means for cooperatively engaging said flanges, a separate plug inserted within each of the cavities formed by the lateral walls of said spacer comprising an elongated body having a wedge-shaped cross-section, the large base of which has laterally extending shoulders adapted to be compressively interposed between the channel and the ends of the lateral walls of said spacer, said body having a lateral dimension so as to place said cooperative engagement means under stress to lock the same, when inserted fully in said cavity.
Claim 10
Dependent Claim
153 words
Apparatus for joining assembly having a pair of open channel members, each having a central portion and substantially normally extending flanges along the longitudinal edges thereof, having engaging means, comprising a spacer adapted to be interposed between said channel members, said spacer being H-shaped in cross-section having a pair of lateral side walls, and a central cross-bar, the ends of the lateral walls of said spacer being formed with means for cooperatively engaging said flanges, a separate plug inserted within each of the cavities formed by the lateral walls of said spacer comprising an elongated body having a wedge-shaped cross-section, the large base of which has laterally extending shoulders adapted to be compressively interposed between the channel and the ends of the lateral walls of said spacer, said body having a lateral dimension so as to place said cooperative engagement means under stress to lock the same, when inserted fully in said cavity.
Claim 11
Dependent Claim
44 words
The apparatus according to claim 8, wherein said plugs having a dimension perpendicular to the lateral so that each is compressed between the cross-bar of the spacer and the channel member to have a force vector extending perpendicular to the cross-bar of said spacer.
Claim 12
Dependent Claim
15 words
The assembly, according to claim 8, wherein said plugs are formed of solid resilient material.
Claim 13
Dependent Claim
14 words
