Utility machine with dual-mode steering
View Patent ↗An apparatus for transporting carts including a machine body, a steering control arranged on the body, a steering pedestal pivotally arranged with respect to the body, and a selection mechanism adapted to be selectively coupleable between the body and the steering pedestal providing for a caster mode and a steering mode respectively. A method of using a dual mode utility machine including depressing a first lever thereby engaging a pivoting selector into a steering pedestal engaging position and controlling the direction of the machine by rotatably manipulating a tiller, and depressing a second lever thereby disengaging the pivoting selector from a steering pedestal engaging position to a body engaging position and controlling the direction of the machine by pushing and/or pulling a machine from side to side via a fixed tiller.
1. An apparatus for transporting carts comprising:
a machine body;
a steering control arranged on the body;
a steering pedestal pivotally arranged with respect to the body;
at least one caster;
a hitch positioned on the body opposite said steering pedestal and adapted to engage a cart; and
a selection mechanism the selection mechanism adapted to be selectively coupleable between the body and the steering pedestal providing for a caster mode and a steering mode respectively, wherein in steering mode, the steering pedestal is operably coupled to the caster such that a change in the pivotal direction of the steering pedestal relative to the machine body causes a substantially corresponding change in the pivotal direction of the at least one caster relative to the machine body, wherein the selection mechanism further comprises a pivoting selector pivotally positionable between a body engaging position and a pedestal engaging position, wherein the body further comprises a fixing element, the fixing element being engageable with the pivoting selector in a body engaging position, wherein the fixing element further comprises a turn center plate, wherein the turn center plate further comprises a centering notch, wherein the pivoting selector includes a body engagement feature adapted to engage the fixing element,
wherein the body engagement feature includes a stepped feature adapted to engage the centering notch.
2. The apparatus of claim 1 , wherein the pivoting selector comprises a guide bar.
3. The apparatus of claim 1 , wherein the pivoting selector further comprises a pedal fixedly connected to the pivoting selector, wherein depressing the pedal positions the pivoting selector in the pedestal engaging position.
4. The apparatus of claim 1 , further comprising a locking latch adapted to engage the pivoting selector.
5. The apparatus of claim 4 , further comprising a pedal pivotally positioned on the steering pedestal, the locking latch being positioned on the pedal, wherein depressing the pedal releases the pivoting selector.
6. The apparatus of claim 5 , further comprising a biasing mechanism configured to bias the pivoting selector in a body engaging position, wherein depressing the pedal pivotally disengages the locking latch from the pivoting selector and the biasing mechanism causes the pivoting selector to rotate into the body engaging position.
7. The apparatus of claim 1 , wherein the steering pedestal is operably coupled to the caster by way of a tiller.
