Locking wheel block

A lockable wheel block adapted to be releasably connected between the rims and tires of a dual wheeled vehicle so as to prevent movement of the wheels in either direction comprising:

• (a) a pair of base members each providing spaced apart curved ramp faces having inner and outer surfaces, said outer surfaces being adapted to engage the circumferential periphery of the tires,
• (b) a horizontal support extending between and fixedly connecting said base members together with said ramp faces in side-by-side spaced apart relation,
• (c) an elongated restraining arm mounted upon said support between said base members and extending in a raised radial direction with respect to said ramp faces,
• (d) mounting means on said support through which said arm is rotatable and longitudinally movable through a raised radial path with respect to said ramp faces,
• (e) means for releasably connecting said restraining arm to said support at preselected positions throughout its length and in a non-rotatable condition, and
• (f) a rim engaging member carried at one end of said restraining arm and rotatable and movable therewith to a position between and behind the rims of the wheeled vehicle when the tires mounted upon the rims are in facial contact with said ramp faces and further rotatable and movable as required to bring said rim engaging member into rim engagement to attach said wheel blocks thereto and to prevent movement of the wheels in either direction.
