Abstract
A three wheel vehicle having an operator seat at its forward end and a step assembly swingably mounted to the vehicle at a point forward of the seat. A control plate of the step assembly is swingably positioned by a powered actuating device. First and second steps are raised and lowered simultaneously by the control plate and in their lowermost position provide step access to the vehicle seat while in an elevated position provide a footrest for a seated operator. Pairs of links interconnect the steps. An additional pair of links connect the control plate to one of the steps. A pair of control bars are attached to and brace the forwardmost step and the vehicle body. A fully retracted position of the step assembly swings the control plate forwardly so that it may serve as a hitch component for coupling to a towing vehicle.
Claims7
A step assembly for a vehicle having a forwardly disposed seat, said assembly comprising,
- a control plate pivotally attached to said vehicle for movement about a horizontal axis,
- step means pivotally secured to said control plate and located forwardly of said vehicle seat and including a step member,
- linkage means pivotally coupling said control plate to said step means,
- control bars releasably attached at one of their ends to said step means and at their opposite ends to the body of said vehicle, and
- powered actuator means carried by said vehicle and coupled to said control plate for positioning said plate about said horizontal axis, wherein control plate movement by said actuator means will position said step means between a lowermost, generally horizontal ground engaging position to function as a step and an inclined elevated position for permitting said step means to function as a footrest for an occupant in said vehicle seat, and wherein said step means may be pivoted from said inclined elevated position to a generally vertical, fully elevated position after said control bars have been disconnected from said step means.
