Adjustable dual-wheel caddy

An adjustable wheel caddy comprising:

• a normally horizontally disposed U-shaped support having opposed legs and a connecting bight therebetween, said bright having an integral rack on an upper surface thereof, one of said legs being integral with said bight and one of said legs being movable, said support being adapted to receive a wheel on the upper portion of said legs;
• opposed roller members mounted internally to said support, said members extending along the internal surfaces of said opposed legs and disposed so that when a wheel is resting on said caddy it will be supported on said rollers;
• wheel means affixed to the lower surface of said U-shaped support for permitting horizontal movement of said caddy;
• and
• adjustment means connecting said movable leg and the bight for displacing said leg toward or away from the leg, said adjustment means including a manual actuator means for permitting displacement of said movable leg only in response to said actuator means so that when a wheel is supported thereon the weight thereof will not displace the leg, said adjustment means comprising
• a sleeve and upwardly extending housing mounted on an end of said movable leg adjacent said bight, said sleeve slidably receiving said rack, a spur gear rotatably mounted within said housing in mesh with said rack, a worm gear rotatably mounted within said housing in mesh with said spur gear and a crank handle integral with said spur extending upwardly and outwardly from said housing and being rotatable relative thereto to drive said spur which in turn translates rotation to linear movement of said sleeve, housing and movable leg along said rack whereby said bight will be increased or decreased in length only in response to rotation of said crank handle.
