Collapsible utility cart
A cart includes a platform assembly, a handle assembly, first wheel assembly and a second wheel assembly. In use, the cart may folded from a deployed position in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may be further integrated into a chair, chaise lounge, garden cart, bicycle utility cart or a bicycle passenger cart.
1. A cart comprising:
a support assembly including:
a seat member comprising a frame and supporting material coupled to the frame, wherein the seat member defines a seating surface configured to support an object,
a first leg member coupled to the seat member frame, and
a second leg member coupled to the seat member frame, the second leg member includes a first portion and a second portion laterally spaced from the first portion;
an axle coupled to the first portion and second portion of the second leg member, the axle extending from the first portion to the second portion, the axle including a distal end and a proximal end, the distal end of the axle extending beyond the first portion of the second leg member and the proximal end of the axle extending beyond the second portion of the second leg member, the distal end of the axle includes a first aperture and a second aperture laterally spaced from the first aperture;
a resilient member disposed within the axle and at least partially extending through the first aperture and the second aperture on the distal end of the axle; and
at least one wheel rotatably coupleable to the distal end of the axle between the first aperture and the second aperture.
2. The cart of claim 1 , wherein the first leg member and second leg member are pivotally coupled to the seat member frame.
3. The cart of claim 2 , wherein the first leg member and second leg member are pivotable from a stowed position to a deployed position, wherein, in the deployed position, the first and second leg members cooperate to support the seat member over a surface.
4. The cart of claim 1 , wherein the proximal end of the axle includes a first aperture and a second aperture laterally spaced from the first axle.
5. The cart of claim 4 , wherein the resilient member is a first resilient member and further comprising:
a second resilient member is disposed within the axle and at least partially extending through the first aperture and the second aperture of the proximal end of the axle.
6. The cart of claim 4 , wherein at least one wheel is a first wheel and further comprising:
a second wheel rotatably coupleable to the proximal end of the axle between the first aperture and the second aperture of the proximal end of the axle.
7. The cart of claim 5 , wherein the first and second resilient members are snap buttons.
8. The cart of claim 1 , further comprising a first bearing and a second bearing, the first and second bearings coupleable to the wheel.
9. A cart comprising:
a support assembly including:
a seat member comprising a frame and supporting material coupled to the frame, wherein the seat member defines a seating surface configured to support an object,
a first leg member coupled to the seat member frame, and
a second leg member coupled to the seat member frame, the second leg member includes a first portion and a second portion laterally spaced from the first portion;
at least one axle slidingly coupled to the first portion of the second leg member, the axle including a distal end and a proximal end, the axle slidingly repositionable between a deployed position and a stored position, where in the deployed position the proximal end of the axle is positioned adjacent to the first portion of the second leg member, and in the stored position the distal end of the axle is positioned adjacent to the first portion of the second leg member; and
at least one wheel rotatably coupleable to the distal end of the axle when the axle is positioned in the deployed position, and decoupled from the distal end of the axle when the axle is positioned in the stored position.
10. The cart of claim 9 , wherein the first leg member and second leg member are pivotally coupled to the seat member frame.
11. The cart of claim 10 , wherein the first leg member and second leg member are pivotable from a stowed position to a deployed position, wherein, in the deployed position, the first and second leg members cooperate to support the seat member over a surface.
12. The cart of claim 9 , wherein the first portion of the second leg member further comprises:
an aperture.
13. The cart of claim 12 , wherein the axle is slidingly engaged to the first portion of the second leg member through the aperture.
14. The cart of claim 9 , wherein the axle further comprises:
a first opening in the distal end of the axle and a second opening in the proximal end of the axle.
15. The cart of claim 14 , wherein the axle further comprises:
a resilient member disposed within the axle and at least partially extending through the first opening the distal end of the axle.
16. The cart of claim 15 , wherein the resilient member is a snap button.
17. The cart of claim 14 , wherein the axle further comprises:
a bolt disposed through the second opening in the proximal end of the axle.
18. The cart of claim 17 , further comprising:
a handle assembly having a substantially U-shaped frame with a first arm, a second arm spaced from the first arm, and an end arm connecting the first arm and the second arm, the handle assembly being pivotally coupled to the support assembly, the handle assembly pivoting from a deployed position, in which the end arm is positioned away from the support assembly, to a stowed position, in which the end arm is positioned proximate to the support assembly.
19. The cart of claim 18 , wherein the handle assembly further comprises:
a support portion that is detachable from the first and second arms of the frame of the handle assembly and pivotable about the end arm of the frame of the handle assembly.
