A plurality of support ribs span between the body and the skirt. The support ribs establish a lifter receiving area together with an outwardly facing surface of the body and an inwardly facing surface of the skirt. A feature is disposed on an outwardly facing surface of the skirt. The feature indicates the location of the lifter receiving area.
Description
BACKGROUND

This invention relates to indicators for carts, and more particularly, to lifter alignment indicators for the carts.


Carts for moving trash, recyclables, and other items are well known. Some municipalities provide residents with carts, especially roll-out carts. The residents load these carts with trash, for example, and, once filled, move the filled carts to a collection location. A trash truck then maneuvers to a position adjacent the collection location. A lifter extending from the trash truck engages a lifter receiving area on the cart before lifting and rotating the cart to a position where the trash pours from the cart into the trash truck. Moving trash from the cart to the truck in this manner is often referred to as “tipping” the cart. Once emptied, the lifter returns the cart to the collection location.


Carts include portions that establish the lifter receiving area. Receiving the lifter within the lifter receiving area facilitates moving or tipping the cart.


SUMMARY

An example cart includes a body establishing an opening for loading and unloading items from the body and a skirt extending downwardly from a portion of the body. A plurality of support ribs span between the body and the skirt. The support ribs establish a lifter receiving area together with an outwardly facing surface of the body and an inwardly facing surface of the skirt. A feature is disposed on an outwardly facing surface of the skirt. The feature indicates the location of the lifter receiving area.


Another example cart includes a body extending axially and establishing an opening for loading and unloading items from the body. A skirt is secured to the body. A plurality of support ribs extend between the skirt and the body. The plurality of ribs, the skirt, and the body establish a lifter receiving area. The skirt includes at least one feature indicating the location of the lifter receiving area.


These and other features of the example disclosure can be best understood from the following specification and drawings, the following of which is a brief description.

DETAILED DESCRIPTION

Referring to FIG. 1, an example roll-out trash cart 10 includes a hollow, axially extending body 14 coverable with a lid member 18. A hinge member 22 connects the lid member 18 to the body 14. The body 14 establishes an opening 20 for loading and unloading items from the body 14. The cart 10 includes handle members 26 and wheels 30 for manipulating the position of the cart 10. Other example uses for the cart 10 include collecting other items, such as recyclable items, non-recyclable items, or leaves.


Referring now to FIGS. 2-6 with continuing reference to FIG. 1, the cart 10 includes a skirt 34 that extends downwardly from an area of the body 14 near the opening 20. The skirt 34 includes an outwardly facing surface 38 and an inwardly facing surface 42. A portion of the skirt 34 is spaced from an outwardly facing surface 46 of the body 14.


In this example, a group of support ribs 50 span between the outwardly facing surface 46 of the body 14 and the inwardly facing surface 42 of the skirt 34. The support ribs 50, the inwardly facing surface 42 of the skirt 34, and the outwardly facing surface 46 of the body 14 establish a lifter receiving area 58 between a portion of the skirt 34 and a portion of the body 14. The lifter receiving area 58 is configured, for example, to receive a lifter 62 from a trash truck. The lifter 62 moves into the lifter receiving area 58 to engage the cart 10. Once engaged with the cart 10, the lifter 62 begins tipping the cart 10.


The support ribs 50a are vertically truncated relative to others of the support ribs 50. In this example, the lifter receiving area 58 is established by the lower edge portions of the support ribs 50a and sides of others of the support ribs 50. The lifter 62 contacts at least some of the support ribs 50 as the lifter 62 engages the cart 10 within the lifter receiving area 58. As can be appreciated, aligning the lifter 62 as the lifter 62 engages the cart 10 facilitates engagement.


In this example, the skirt 34 includes a plurality of alignment features 66 disposed on or near the outwardly facing surface 38 of the skirt 34. The alignment features 66 are corrugations 70a and 70b of the skirt 34 in this example. The corrugations 70a extend axially further than the corrugations 70b. In this example, the corrugations 70a correspond to the horizontal boundary or width of the lifter receiving area 58. The corrugations 70b are horizontally aligned with the support ribs 50a.


An operator (not shown) directing the lifter 62 into the lifter receiving area 58 would understand to align the lifter 62 horizontally between the corrugations 70a. The varied axial lengths of the corrugations 70a and 70b thus facilitates aligning the lifter 62 as the lifter 62 moves to an engaged position with the cart 10. That is, the varied axial lengths of the corrugations 70a and 70b provides a visual hint to location of the lifter receiving area 58, which facilitates aligning the lifter 62 as the lifter 62 is received within the lifter receiving area 58.


Referring to the FIG. 7 example, the alignment features 66 comprise corrugations 70c and indicator ribs 74. The indicator ribs 74 extend away from the outwardly facing surface 38 of the skirt 34. In this example, the corrugations 70c extend axially similar distances and the indicator ribs 74 correspond to the horizontal boundary or width of the lifter receiving area 58. The corrugations 70c and indicator ribs 74 thus provide a visual hint to location of the lifter receiving area 58, which facilitates aligning the lifter 62 as the lifter 62 is received within the lifter receiving area 58.


Referring to the FIG. 8 example, the alignment features 66 comprise corrugations 70a and 70b, and indicator ribs 78. In this example, the indicator ribs 78 extend outwardly from the corrugations 70a. The axial lengths of the indicator ribs 78 correspond generally to the axial lengths of the corrugations 70a. As can be appreciated, the axial length of the indicator ribs 78 and the corrugations 70a is greater than the axial length of the corrugations 70b. The differences between axial lengths of the corrugations 70b, and the indicator ribs 78 and the corrugations 70a provide a visual hint to location of the lifter receiving area 58, which facilitates aligning the lifter 62 as the lifter 62 is received within the lifter receiving area 58.


Features of the disclosed examples include providing a visual hint to the location the lifter receiving area. The visual hint is provided near an outwardly facing surface of the lifter.
