Abstract: A device for preventing vehicles having conventional tandem wheels from moving when parked. The friction of novel dual opposing horizontal shoes pressing against the tires of the tandem wheels prevents the wheels from rotating. A cam and lever action locks the shoes in position against the tires.

Abstract: A retractable wheel assembly for attachment to a boat or other objects to be transported over a hard surface. The assembly comprises a mounting bracket for mounting to the object to be transported. A wheel strut having foldable arm portions pivotally connected to the mounting bracket, a first lock assembly for locking the folded arm portions in a stowed or wheel deployable position and a second lock assembly for locking the arms in both a wheel stowed position and in a wheel deployed position.

Abstract: An outboard boat motor handling and storing apparatus which may be mounted in the back of a vehicle, i.e., pickup truck, van, sportwagon, etc. for the field handling, transporting and storing of an outboard motor. The apparatus comprises an elongated member which is mounted for translation between a stowed position within the confines of the vehicle to a deployed position where it extends beyond the confines of the bed of the vehicle and the lowered tail gate if the vehicle is a pickup truck; and motor attachment member which is attached to and rotates longitudinally relative to the elongated member, the attachment includes a base which pivots vertically relative to the elongated member attachment. With the elongated member in a deployed position, the motor is attached to the base, which is positioned perpendicular relative to the elongated member; the base member is then pivoted substantially parallel with that elongated member, and the motor attachment member is then rotated approximately 180.degree.

Abstract: The collapsible hand truck disclosed includes a pair of spaced-apart, segmented, upright frame members, their segments each being pivotly connected to a "U" bracket; The upright frame members each having a handle and a wheel at opposite ends; The handles and wheels extending in the same direction from the upright members; A load-carrying bracket is rotatably connected between the upright members near the handle ends; Brace members are rotatably connected to the upright members between the "U" bracket and wheel ends; and A weight support bracket is rotatably and pivotly connected between the upright frame members and when in an operable position extends outwardly from the upright frame members on the opposite side from the handles and wheels.
