Abstract

A trailer assembly is provided for a wagon. The trailer assembly has a trailer frame comprising a first frame pivotally connected to the wagon, a second frame pivotally connected to the wagon, and a first link pivotally connecting the first frame to the second frame. The trailer frame is positionable between a first or use position and a second or folded position, A wheel is rotatedly connected to the trailer frame to support the trailer frame in the use position.

First claim

What is claimed is:

1. A trailer for a wagon, comprising:
a first trailer frame pivotally connected to the wagon;
a first platform secured to the first trailer frame, an opening through the first trailer frame at a location adjacent the first platform;
a second trailer frame pivotally connected to the wagon;
a second platform secured to the second trailer frame, and wherein the second platform is below the opening in the first trailer frame when the trailer is in the use position;
a first link pivotally connecting the first trailer frame to the second trailer frame;
a second link pivotally connecting the first trailer frame to the second trailer frame;
a first wheel rotatedly connected to one of the first link and the second trailer frame; and,
a second wheel rotatedly connected to one of the second link and the second trailer frame, wherein the trailer is positionable between a first or use position and a second or folded position.

2. The trailer of claim 1 , wherein in the use position the first trailer frame is positioned in a first plane, the second trailer frame is positioned in a second plane, and wherein the first plane and the second plane are spaced apart a first distance and are in different but generally parallel planes.

3. The trailer of claim 2 , wherein in the folded position the first trailer frame is positioned in a third plane, the second trailer frame is positioned in a fourth plane, wherein the third plane and the fourth plane are spaced apart a second distance and are in different but generally parallel planes, and wherein the second distance is less than the first distance.

4. The trailer of claim 1 , further comprising a first bracket connected to the wagon and the first trailer frame being pivotally connected to the first bracket at a first pivot point, and a second bracket connected to the wagon and the second trailer frame being pivotally connected to the second bracket at a second pivot point, and wherein the second pivot point is positioned further from the wagon than the first pivot point.

5. The trailer of claim 4 , further comprising a stop connected to the second bracket to engage the second trailer frame and prevent the second trailer frame from continued rotation beyond the second position.

6. The trailer of claim 1 , further comprising a receiver connected to the first trailer frame, the receiver engaging the second trailer frame in the folded position to retain the second trailer frame adjacent the first trailer frame in a substantially vertical position.

7. The trailer of claim 1 , further comprising a first platform secured to the first trailer frame, an opening through the first trailer frame at a location adjacent the first platform, a second platform secured to the second trailer frame, and wherein the second platform is below the opening in the first trailer frame when the trailer is in the use position.

8. The trailer of claim 1 , wherein the first wheel and the second wheel are caster wheels.

9. A trailer for a wagon, comprising:
a trailer frame comprising a first upper trailer frame pivotally connected to the wagon, a second lower trailer frame pivotally connected to the wagon, a first link pivotally connecting the first upper trailer frame to the second lower trailer frame, a first platform secured to the first upper trailer frame and an opening through the first upper trailer frame at a location adjacent the first platform, and a second platform secured to the second lower trailer frame, wherein the trailer frame is positionable in a first or use position and a second or folded position, and wherein the second platform is positioned below the opening in the first upper trailer frame when the trailer frame is in the use position; and,
a first wheel rotatedly connected to the trailer frame to support the trailer frame in the use position.

10. The trailer of claim 9 , wherein in the use position, the first upper trailer frame is positioned in a first plane, the second lower trailer frame is positioned in a second plane, and wherein the first plane and the second plane are spaced apart a first distance and are in different but generally parallel planes.

11. The trailer of claim 10 , wherein in the folded position, the first upper trailer frame is positioned in a third plane, the second lower trailer frame is positioned in a fourth plane, wherein the third plane and the fourth plane are spaced apart a second distance and are in different but generally parallel planes, and wherein the second distance is less than the first distance.

12. The trailer of claim 9 , further comprising a receiver connected to the first upper trailer frame, the receiver engaging the second lower trailer frame in the folded position to retain the second lower trailer frame adjacent the first upper trailer frame in a substantially vertical position when the trailer is in the second position.

13. The trailer of claim 9 , further comprising a first bracket connected to the wagon and the first upper trailer frame being pivotally connected to the first bracket at a first pivot point, and a second bracket connected to the wagon and the second lower trailer frame being pivotally connected to the second bracket at a second pivot point, and wherein the second pivot point is positioned further from the wagon than the first pivot point.

14. The trailer of claim 13 , further comprising a stop connected to the second bracket to engage the second lower trailer frame and prevent the second lower trailer frame from continued rotation beyond the second position.

15. A trailer for a wagon, comprising:
a trailer frame comprising a first frame pivotally connected to the wagon, the first frame having an upper and lower surface, a second frame pivotally connected to the wagon, the second frame having an upper and lower surface, and a first link pivotally connecting the first frame to the second frame; and,
a wheel rotatedly connected to the trailer frame, wherein the trailer frame is positionable between a first or use position and a second or folded position, wherein in the use position the first frame is positioned in a first plane and the second frame is positioned in a second plane, and the lower surface of the first frame is adjacent the upper surface of the second frame, the first plane and the second plane being spaced apart a first distance and being in different but generally parallel planes, and wherein in the folded position the first frame is positioned in a third plane and the second frame is positioned in a fourth plane, and the lower surface of the first frame is adjacent the upper surface of the second frame, wherein the third plane and the fourth plane being spaced apart a second distance and being in different but generally parallel planes, and wherein the second distance is less than the first distance.

16. The trailer of claim 15 , further comprising a receiver connected to the first frame, the receiver engaging the second frame in the folded position to retain the second frame adjacent the first frame in a substantially vertical position.

17. The trailer of claim 16 , further comprising a first bracket connected to the wagon and the first frame being pivotally connected to the first bracket at a first pivot point, and a second bracket connected to the wagon and the second frame being pivotally connected to the second bracket at a second pivot point, and wherein the second pivot point is positioned further from the wagon than the first pivot point.

18. The trailer of claim 17 , further comprising a stop connected to the second bracket to engage th
