Abstract
A frame member is provided for a structure. The frame member includes a generally flat, elongated first surface having an elongated slot therein extending along an axis. The slot is defined by first and second converging sidewalls lying in corresponding planes which are at acute angles to the first surface. A first diverging outer abutment wall is generally perpendicular to the first converging sidewall and a second diverging outer abutment wall is generally perpendicular to the second converging sidewall. A first diverging inner abutment wall is generally perpendicular to the second converging sidewall and a second diverging inner abutment wall is generally perpendicular to the first converging sidewall.

A frame member for a structure, comprising:
- a generally flat, elongated first surface having an elongated slot therein extending along an axis, the slot being defined by:
- first and second generally flat, converging sidewalls, the first and second converging sidewalls lying in corresponding planes which are at acute angles to the surface and having terminal ends;
- first and second diverging outer abutment walls which extend from the terminal ends of the first and second converging sidewalls and have terminal ends, the first and second diverging outer abutment walls being non-parallel to the first surface;
- first and second diverging inner abutment walls extending from the terminal ends of the first and second outer diverging sidewalls toward the surface, the first and second diverging inner abutment walls having terminal ends;
- and
- a generally concave terminal wall interconnecting the terminal ends of the first and second diverging inner abutment walls.
