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.
Claims12
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.
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.
