Abstract

A shade assembly for a wagon having a collapsible shade frame that transitions between an assembled state for providing shade and a disassembled state for stowing. The shade frame has at least a pair of long rods each having a distal end and a mounting end removably mountable to a mounting holder on a frame of the wagon. The long rods each has a plurality of rod sections in the disassemble state, and the rod sections are removably connected end-to-end to form corresponding long rods arranged in a cross configuration to form a support frame in the assembled state. A canopy comprising a shade material is supported on the support frame of the shade frame in the assembled state. Under the weight of the canopy, the shade frame is cantilevered at the mounting ends of the long rods by the mounting holder.

Claims (25)

1. A shade assembly for a wagon, comprising:

a collapsible shade frame that transitions between an assembled state for providing shade and a disassembled state for stowing, comprising at least a pair of long rods each having a distal end and a mounting end removably mountable to a mounting holder on a frame of the wagon, wherein the long rods each comprises a plurality of rod sections in the disassemble state, and wherein the rod sections are removably connected end-to-end to form corresponding long rods arranged in a cross configuration to form a support frame in the assembled state; and

a canopy comprising a shade material supported on the support frame of the shade frame in the assembled state,

wherein under weight of the canopy, the shade frame is cantilevered at the mounting ends of the long rods by the mounting holder.

2. The shade assembly as in claim 1 , wherein the distal ends of the long rods are not supported and are free to move under the weight of the canopy.

3. The shade assembly as in claim 2 , wherein the shade frame is flexible in the assembled state to allow bending/bowing to support the shade material to form generally a dome shaped canopy.

4. The shade assembly as in claim 3 , the long rods are flexible overall, to apply biasing force on the shade material to keep it taut to form the dome shaped canopy.

5. The shade assembly as in claim 4 , wherein the canopy has a lateral span of an area larger than a total area of the wagon footprint.

6. The shade assembly as in claim 5 , wherein the mounting holders are located at mounting locations aligned on a same side of the wagon.

7. The shade assembly as in claim 1 , wherein the canopy extends with the long rods cantilevered from the mounting holders at mounting locations along a same side of the wagon.

8. The shade assembly as in claim 7 , wherein the mounting holders are located at rear and front frames along the same side of the wagon.

9. The shade assembly as in claim 8 , wherein the mounting holders each has a cylindrical holder that is sized to receive insertion of the mounting end of the long rod.

10. The shade assembly as in claim 1 , wherein the rod sections are coupled by a cord running through all the rod sections of the respective long rods in the disassembled state to facilitate connection of the rod sections in a specific desired order.

11. The shade assembly as in claim 8 , wherein the cord is elastic.

12. The shade assembly as in claim 8 , wherein the rod sections are made of at least one of aluminum, plastic, carbon fiber, and a combination thereof.

13. The shade assembly as in claim 1 , wherein the canopy further comprises guides provided on the surface of the shade material, wherein a first one of the long rods is inserted through the guides in a longitudinal direction from an edge of the shade material, diagonally across the underside and through a center portion of the shade material, and a second one of the long rods is inserted through the guides in a longitudinal direction crossing (e.g., generally orthogonal to) the longitudinal direction of the first one of the long rods, thus forming the cross configuration of the support frame for the shade material.

14. The shade assembly as in claim 13 , wherein the guides for the two long rods run along a top surface or a bottom surface of the shade material.

15. The shade assembly as in claim 13 , wherein at least one of the rod sections has at least one anchoring loop or anchoring hook, and the shade material has a corresponding anchoring hook or anchoring hoop at a guide near the edge of the shade material to keep the shade material taut to form the dome shaped canopy.

16. The shade assembly as in claim 1 , wherein the canopy comprises at least a flap on a side for providing shading from oblique sun rays and/or providing privacy from view from a lateral side.

17. A wagon, comprising:

a wagon frame assembly; and

a shade assembly as in claim 1 , removably coupled to the wagon frame assembly.

18. The collapsible wagon as in claim 17 , wherein the mounting holders are provided at mounting locations of a front frame and a rear frame, which are aligned on the same side of the wagon.

19. The collapsible wagon as in claim 18 , wherein the wagon frame structure is collapsible into a folded structure.

20. The collapsible wagon as in claim 19 , wherein the rear frame supports rear wheels at the base of the rear frame, and wherein the collapsible wagon frame assembly further comprises a collapsible frame having a front frame supporting front wheels at a base of the front frame, and a pair of side frames that are each pivotally collapsible, wherein the front frame, the rear frame and the pair of side frames in their extended state define a space for receiving a basket for holding items to be transport by the collapsible wagon.
