Abstract
Abstract A display stand for use as shelving having vertical corner members joined by horizontal members adapted to support flat shelves or plates of any suitable material. The corner members and support members are tubular, and are telescopingly connected together by a channel or U-shaped stub or projection secured to one of said members and adapted to telescope into the open end of the other member, a clip frictionally held in the projection, an internally threaded bearing member supported in the clip and having a top bearing surface to frictionally engage the interior surface of the telescoping tubular member, and a threaded stud received in the bearing and acting to urge the bearing against the interior surface of the tubular member for detachably but rigidly joining said members.

Claim 1
Independent Claim
242 words
A tube connecting means for joining an open-ended tubular member to a second member, comprising a generally channel-shaped stub secured to the second member and telescopingly received in the open end of the tubular member, a clip member received and adjustable in the channel of the stub, a bearing member supported by said clip member, and means to urge the bearing member into frictional engagement with the interior surface of the tubular member, said stub has a base and generally parallel sides with the clip member longitudinally adjustable of the stub, said clip member is generally U-shaped with a base having an opening therein and generally parallel sides, the sides of the clip member frictionally engaging the sides of the stub, said bearing member having an internally threaded generally cylindrical stem received in said opening and a generally flat flange integral with said stem and positioned adjacent the exterior surface of the clip member base, and said urging means comprises a set screw adapted to be received in said bearing member and clip member with the inner end of the screw engaging the interior surface of the stub base to force said bearing member outwardly into engagement with the interior surface of the tubular member, said tubular member having an opening adapted to be axially aligned with the opening in the clip member and said cylindrical stem and set screw when the tubular member is telescoped in operative position on said stub.

Claim 3
Dependent Claim
192 words
A tube connecting means for joining an open-ended tubular member to a second member, comprising a generally channel-shaped stub secured at one end to the second member and telescopingly received in the open end of the tubular member, a bearing member in said tubular member having a flanged base seating upon the interior wall of said tubular member, an internally threaded stem projecting upwardly with its threaded opening in alignment with an opening in said inner wall, and a set screw threaded into said stem with the inner end of the screw when tightened frictionally engaging the interior surface of the base of the stub and the flanged base of the bearing member held against the interior wall of the tubular member, said stub having a base and depending generally parallel sides, a U-shaped clip member received in the channel of the stub and longitudinally adjustable therein, the clip member having an opening movable into alignment with an opening in the adjacent wall of the tubular member for access to the bearing member, and means to urge and maintain the bearing member in engagement with the inner surface of the tubular member.
