ABSTRACT:
A kit for assembling wood legs to form an A-frame to support the end of a cross beam for a children's play gym includes a trapezoidal frame bracket to connect the upper ends of the legs to each other and to the cross beam and a special frame brace for reinforcing that connection which will accommodate a tubular metal cross beam or a cross beam consisting of a single board or a plurality of boards. The frame brace has a generally rectangular top wall and a pair of laterally spaced apart side walls extending down from the top wall at an angle such that the side walls have more or less the same slope as the side edges of the frame bracket. Portions of the frame brace top wall define a first set of holes spaced apart along the longitudinal centerline of the top wall, there being two such holes in the first set and a second set of holes containing at least two holes spaced along the top wall on each side of that centerline. There also may be a third set of holes containing at least two holes spaced along the top wall on each side of the centerline and being displaced from the second set of holes. The kit also includes fasteners arranged to extend through the first set of holes into the cross beam when the cross beam is a unitary member and through the second and third sets of holes into the cross beam when the cross beam is of wood so that the same hardware can be used to construct play gyms having a variety of different type cross beams.
