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
A manual pallet jack propelling system comprising:
- (a) a motive device comprising a motive device coupling structure;
- (b) a hitch mechanism removably coupled to the motive device coupling structure, the hitch mechanism comprising:
- (i) a proximal hitch body comprising a motive device coupling mechanism at a proximal end thereof, wherein the coupling mechanism is removably coupleable with the motive device coupling structure;
- (ii) a tensioned piston assembly comprising:
- (A) a stationary piston body fixedly coupled to the proximal hitch body;
- and
- (B) an extendable tensioned piston rod extending from the stationary piston body;
- (iii) a distal hitch body fixedly coupled to the extendable tensioned piston rod, wherein the distal hitch body is removably coupleable to a manual pallet jack at a mateable coupling structure;
- (iv) a mateable coupling structure disposed on the distal hitch body;
- and
- (v) an actuation assembly operably coupled to the distal hitch body, wherein actuation of the actuation assembly can urge the distal hitch body between a raised position and a lowered position;
- and
- (c) a release actuation mechanism disposed on the manual pallet jack, wherein the release actuation mechanism is disposed in contact with a hydraulic release button, wherein actuation of the release actuation mechanism causes actuation of the hydraulic release button.

A hitching system for coupling to a manual pallet jack, the system comprising:
- (a) a hitch mechanism comprising:
- (i) a distal hitch body comprising a mateable coupling structure disposed on the distal hitch body;
- (ii) a proximal hitch body;
- (iii) a tensioned piston assembly coupled to the proximal hitch body and the distal hitch body;
- and
- (iv) an actuation assembly operably coupled to the distal hitch body, wherein actuation of the actuation assembly can move the distal hitch body between a raised position and a lowered position;
- and
- (v) a motive device coupling mechanism disposed at a proximal end of the proximal hitch body;
- and
- (b) a release actuation mechanism disposed on the manual pallet jack, wherein the release actuation mechanism is disposed in proximity with a release button, wherein actuation of the release actuation mechanism causes actuation of the release button.
