ABSTRACT:
A roller bracket apparatus includes a roller assembly which includes a carriage portion and a link portion projecting from the carriage portion. A push/pull assembly is provided, and a pivot assembly is connected between the link portion of the roller assembly and the push/pull assembly. The carriage portion includes a wheel-support portion and a plurality of axle/wheel assemblies supported by the wheel-support portion. Each of the axle/wheel assemblies includes an axle and a roller wheel connected to the axle. The link portion extends from the carriage portion at an oblique extension angle. The push/pull assembly includes a first member connected to the pivot assembly, and a second member is connected to the first member. The push/pull assembly also includes a third member connected between the first member and the second member. The second member of the push/pull assembly is oriented with respect to the link portion of the roller assembly substantially in a straight line when the second member of the push/pull assembly is oriented with respect to the wheel-support portion of the roller assembly at a right angle. On the other hand, the second member of the push/pull assembly is oriented with respect to the link portion in an oblique link-to-second-side orientation angle when the second member is oriented with respect to the wheel-support portion in a straight line. The link-to-second-member orientation angle is less than the extension angle.
