Abstract: A portable, foldable basketball backboard assembly. In an upright deployed position the assembly is erected to provide a regulation size basketball backboard. The assembly may be folded downwardly into a compact, folded assembly that is sufficiently compact in size and short in height to permit it to be transported and stored in ordinary storage facilities. In the folded position the assembly is transportable on integral caster wheel assemblies. The assembly is raised and lowered by a lift mechanism which facilitates raising of the assembly while also preventing the assembly from being lowered suddenly or unexpectedly. An extendible goal post, which supports a foldable backboard and a hoop, extends upwardly and outwardly from the base so as to provide a clear playing space beneath the backboard.

Abstract: A portable, foldable basketball backboard assembly is disclosed. In an upright deployed position the assembly is erected to provide a regulation size basketball backboard. The assembly may be folded into a compact assembly sized for storage and transportation. In the folded position the assembly is transportable on integral wheel assemblies. The assembly includes an integral spring biasing mechanism to assist in raising the assembly to the upright position.

Abstract: A power driven wrench includes a rotatable drive rotor journalled between fixed arms of a yoke affixed to one end of a wrench handle containing a motor. Disposed between the yoke arms is a ratchet head which is driven in reciprocal angular motion by the motor. The ratchet head is engaged with the drive rotor by means of a pawl in the ratchet head and a ratchet gear on the drive rotor. A direction switching lever within the ratchet head permits the direction of rotation of the drive rotor to be manually selected. The switching lever extends from the sides of the ratchet head, such that the direction of rotation of the wrench can be easily changed even if the wrench is inadvertently backed up against an immovable object while removing a nut or bolt. The location of the switching lever enables it be actuated with the same hand holding the wrench, and also results in the wrench having a thin profile which is useful in confined spaces.
