Abstract

Claims (63)

1. A ladder tray system comprising:

a ladder having an in-use orientation and a stored orientation comprising:

a front rail comprising a front rail width dimension and a front rail depth dimension;

a rear rail coplanar with the front rail in the in-use orientation comprising a rear rail depth dimension;

a step;

a platform; and

a tray comprising:

a tray width dimension;

a tray height dimension;

a tray depth dimension; and

a tray shoulder comprising a tray shoulder depth dimension and a tray shoulder width dimension, the tray shoulder depth dimension being less than the tray depth dimension;

a ladder width boundary;

a combined rail depth boundary; and

wherein the tray width dimension fits within the ladder width boundary when the ladder is in the stored orientation;

wherein the tray depth dimension fits within the combined rail depth boundary when the ladder is in the stored orientation; and

wherein the tray shoulder depth dimension is less than or equal to the rear rail depth dimension.

2. The ladder tray system of claim 1 wherein the tray shoulder width dimension is less than or equal to the front rail width dimension.

3. The ladder tray system of claim 2 further comprising a platform gap dimension and wherein the tray height dimension fits within the platform gap dimension when the ladder is in the stored orientation.

4. The ladder tray system of claim 2 wherein the shoulder comprises a tool aperture.

5. The ladder tray system of claim 2 further comprising a hanging bar.

6. The ladder tray system of claim 2 further comprising a link between the tray and platform wherein pivoting the platform with respect to the front rail or rear rail results in pivoting of the tray.

7. The ladder tray system of claim 6 further comprising a tray bottom surface wherein the tray bottom surface is substantially parallel to the rear rail when the ladder is in the stored orientation.

8. The ladder tray system of claim 6 wherein the tray rests entirely within a combined rail depth boundary when the ladder is in the stored orientation.

9. The ladder tray system of claim 2 wherein the tray depth dimension is larger the rear rail depth dimension and larger than the front rail depth dimension.

10. The ladder tray system of claim 2 further comprising a rail interior width dimension wherein the wherein the tray width boundary fits within the rail interior width dimension when the ladder is in the stored orientation.

11. The ladder tray system of claim 3 wherein the tray depth dimension is larger the rear rail depth dimension and larger than the front rail depth dimension.

12. A tray for use in combination with a ladder, the tray comprising:

a tray width dimension;

a tray height dimension;

a tray depth dimension; and

a tray shoulder comprising a tray shoulder depth dimension and a tray shoulder width dimension, the tray shoulder depth dimension being less than the tray depth dimension;

wherein the tray has an in-use orientation and a stored orientation and is pivotably attached to a ladder, the ladder comprising:

a front rail comprising a front rail width dimension and a front rail depth dimension;

a rear rail coplanar with the front rail in the in-use orientation comprising a rear rail depth dimension;

a step; and

a platform;

wherein the tray shoulder width dimension is less than or equal to the front rail width dimension and the tray shoulder depth dimension is less than or equal to the rear rail depth dimension.

13. The of claim 12 further comprising a platform gap dimension and wherein the tray height dimension fits within the platform gap dimension when the tray is in the stored orientation.

14. The tray of claim 12 wherein the ladder further comprises:

a ladder width boundary;

a combined rail depth boundary; and

wherein the tray width dimension fits within the ladder width boundary when the tray is in the stored orientation; and

wherein the tray depth dimension fits within the combined rail depth boundary when the tray is in the stored orientation.

15. The tray of claim 14 wherein the tray rests entirely within a combined rail depth boundary when the tray is in the stored orientation.

16. The tray of claim 15 wherein the tray depth dimension is larger than the rear rail depth dimension.

17. The tray of claim 16 wherein the tray depth dimension is larger than the front rail depth dimension.

18. The ladder tray system of claim 12 wherein the shoulder comprises a tool aperture.

19. The ladder tray system of claim 16 further comprising a link between the tray and platform wherein pivoting the platform with respect to the front rail or rear rail results in pivoting of the tray.

20. A ladder having an in-use orientation and a stored orientation comprising:

a front rail comprising a front rail width dimension and a front rail depth dimension;

a rear rail coplanar with the front rail in the in-use orientation comprising a rear rail depth dimension;

a step;

a tray comprising:

a tray width dimension;

a tray height dimension;

a tray depth dimension; and

a tray shoulder comprising a tray shoulder depth dimension and a tray shoulder width dimension, the tray shoulder depth dimension being less than the tray depth dimension;

a ladder width boundary;

a combined rail depth boundary; and

wherein the tray width dimension fits within the ladder width boundary when the ladder is in the stored orientation;

wherein the tray depth dimension fits within the combined rail depth boundary when the ladder is in the stored orientation;

wherein the tray shoulder depth dimension is less than or equal to the rear rail depth dimension; and

wherein the tray shoulder width dimension is less than or equal to the front rail width dimension.
