DUMP CART
A dumping cart is disclosed. The cart allows for complete dumping while maintaining four wheels on the ground and can rotate the rear set of wheels to allow the bed of the cart to be completely turned over for emptying. Also disclosed is a method of attaching an article retaining bed to a cart.
1 . A dumping cart for use on the ground, comprising:
a chassis;
an article retaining bed pivotably coupled to the chassis along an articulation axis, the article retaining bed comprising a retaining bed floor;
a set of front wheels having a front wheel rotation axis and operably coupled to the chassis;
a set of rear wheels having a rear wheel rotation axis and operably coupled to the article retaining bed;
wherein the articulation axis is shiftable between:
a carry orientation wherein the articulation axis is intermediate article retaining bed floor and the rear wheel rotation axis and both the set of front wheels and set of rear wheels contact the ground; and
a full-dump orientation wherein the articulation axis is intermediate the rear wheel rotation axis and the ground; and
wherein the cart is used on the ground and the article retaining bed floor is parallel to the ground when the articulation axis is in carry orientation and when the articulation axis is in the full-dump orientation.
2 . The dumping cart of claim 1 wherein the set of front wheels contacts the ground and the rear wheels do not contact the ground when the articulation axis is in the full-dump orientation.
3 . The dumping cart of claim 1 wherein the articulation axis is further shiftable to an over-dump configuration wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the article retaining bed floor.
4 . The dumping cart of claim 1 , wherein the articulation axis is further shiftable to a dump orientation wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the articulation axis.
5 . The dumping cart of claim 3 , wherein the retaining bed floor is not parallel to the ground when the articulation axis is in the over-dump configuration.
6 . The dumping cart of claim 2 , wherein the rear set of wheels is above the article retaining bed.
7 . The dumping cart of claim 2 , wherein the article retaining bed is comprised of a front wall, a rear wall, a right side wall, and a left side wall, and wherein the front wall, rear wall, right side wall, and left side wall all contact the ground when the dumping cart is in the full-dump orientation.
8 . The dumping cart of claim 4 , wherein the set of rear wheels is intermediate the set of front wheels and the article retaining bed when the articulation axis is in the dump orientation.
9 . The dumping cart of claim 8 , wherein the set of rear wheels is intermediate the front wheel rotation axis and the bed floor when the articulation axis is in the dump orientation.
10 . A dumping cart for use on the ground, comprising:
a chassis;
an article retaining bed pivotably coupled to the chassis along an articulation axis, the article retaining bed comprising a bed floor;
a set of front wheels having a front wheel rotation axis and operably coupled to the chassis;
a set of rear wheels having a rear wheel rotation axis and operably coupled to the article retaining bed;
wherein the articulation axis is shiftable between:
a carry orientation wherein the articulation axis is intermediate the article retaining bed floor and the rear wheel rotation axis and both the set of front wheels and set of rear wheels contact the ground; and
a full-dump orientation wherein the set of rear wheels do not contact the ground; the articulation axis is intermediate the rear wheel rotation axis and the article retaining bed floor;
and the set of front wheels maintains contact with the ground.
11 . The dumping cart of claim 10 , wherein the set of rear wheels is above the article retaining bed when in the full-dump orientation.
12 . The dumping cart of claim 11 , wherein the article retaining bed floor is parallel to the ground when in the full-dump orientation.
13 . The dumping cart of claim 10 , wherein the article retaining bed is comprised of a front wall, a rear wall, a right side wall, and a left side wall, and wherein the front wall, rear wall, right side wall, and left side wall all contact the ground when the dumping cart is in the full-dump orientation.
14 . The dumping cart of claim 13 , wherein the articulation axis is further shiftable to an over-dump orientation wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the articulation axis.
15 . The dumping cart of claim 14 wherein the retaining bed floor is not parallel to the ground when the articulation axis is in the over-dump configuration.
16 . The dumping cart of claim 15 , wherein the articulation axis is further shiftable to a dump orientation wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the articulation axis and the set of rear wheels is intermediate the set of front wheels and the article retaining bed.
17 . A dumping cart for use on the ground, comprising:
a chassis;
an article retaining bed pivotably coupled to the chassis along an articulation axis, the retaining bed comprising a bed floor;
a pair of front wheels having a front wheel rotation axis and operably coupled to the chassis;
a pair of rear wheels having a rear wheel rotation axis and operably coupled to the article retaining bed;
wherein the articulation axis is shiftable between:
a dump orientation wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the articulation axis;
an over-dump orientation wherein the rear wheel rotation axis is intermediate the front wheel rotation axis and the articulation axis and the articulation axis is intermediate the rear wheel rotation axis and the ground; and
a full-dump orientation wherein the articulation axis is intermediate the rear wheel rotation axis and the article retaining bed floor.
18 . The dumping cart of claim 17 , wherein the bed floor is parallel to the ground when the articulation axis is in the full-dump configuration.
19 . The dumping cart of claim 17 , wherein the set of rear wheels is intermediate the front wheel rotation axis and the article retaining bed when in the dump orientation.
20 . The dumping cart of claim 17 , wherein the articulation axis is further shiftable to a carry orientation wherein the articulation axis is intermediate article retaining bed floor and the rear wheel rotation axis and both the set of front wheels and set of rear wheels contact the ground.
