Abstract
The various embodiments disclosed herein relate to an interchangeable hitch mechanism that is coupleable to a pusher device. Other implementations relate to a pusher device having such an interchangeable hitch mechanism that can be removably coupleable to a manual jack pallet.
Claims20
An interchangeable hitch mechanism comprising:
- (a) a distal hitch body;
- (b) an angled coupling feature defined at or near the distal end of the distal hitch body;
- (c) a mateable coupling structure disposed on the distal hitch body;
- (d) a proximal hitch body;
- (e) a tensioned piston assembly comprising:
- (i) a stationary piston body fixedly coupled to the proximal hitch body;
- and
- (ii) an extendable tensioned piston rod extending from the stationary piston body, the extendable tensioned piston rod fixedly coupled to the distal hitch body;
- and
- (f) a pusher device coupling mechanism disposed at a proximal end of the proximal hitch body.

A pusher device for coupling to and propelling a manual jack pallet, the pusher device comprising:
- (a) a pusher body;
- (b) at least two wheels operably coupled to the pusher body;
- (c) an actuator operably coupled to at least one of the at least two wheels;
- (d) a steering mechanism coupled to the at least one of the at least two wheels;
