Abstract

A roof assembly for a work vehicle includes a roof panel having a vertical peak positioned longitudinally between a forward end and a rearward end of the roof panel. In addition, the roof panel includes a forward surface extending from the vertical peak to the forward end of the roof panel, and the roof panel includes a rearward surface extending from the vertical peak to the rearward end of the roof panel. The roof panel also includes a ridge extending around a periphery of the roof panel. The ridge has a first gap positioned at the rearward end of the roof panel, a second gap positioned at the forward end of the roof panel, and a third gap positioned at a first lateral end of the roof panel. In addition, the roof panel does not include a channel extending along the roof panel.

First claim

The invention claimed is:

1. A roof assembly for a work vehicle, comprising:
a roof panel comprising:
a vertical peak positioned longitudinally between a forward end and a rearward end of the roof panel;
a forward surface extending from the vertical peak to the forward end of the roof panel;
a rearward surface extending from the vertical peak to the rearward end of the roof panel; and
a ridge extending around a periphery of the roof panel, wherein the ridge has a first gap positioned at the rearward end of the roof panel, a second gap positioned at the forward end of the roof panel, and a third gap positioned at a first lateral end of the roof panel;
wherein the roof panel does not include a channel extending along the roof panel.

2. The roof assembly of claim 1 , wherein the forward surface has a first portion extending from the vertical peak, the forward surface has a second portion extending from the forward end of the roof panel, the forward surface has a third portion extending between the first and second portions along a longitudinal axis of the roof assembly, and a slope of the third portion relative to a horizontal plane is greater than slopes of the first and second portions relative to the horizontal plane.

3. The roof assembly of claim 1 , wherein the ridge has a fourth gap positioned at the forward end of the roof panel and spaced apart from the second gap along a lateral axis of the roof assembly.

4. The roof assembly of claim 3 , wherein the ridge has a first curved surface extending from a lateral central portion of the ridge to the second gap, and the ridge has a second curved surface extending from the lateral central portion of the ridge to the fourth gap.

5. The roof assembly of claim 1 , wherein the third gap is configured to be substantially aligned with a door hinge of the work vehicle along a longitudinal axis of the roof assembly.

6. The roof assembly of claim 1 , wherein the ridge has a fifth gap positioned at a second lateral end of the roof panel, opposite the first lateral end.

7. The roof assembly of claim 1 , wherein the third gap is positioned on a sloped surface of the roof panel.

8. The roof assembly of claim 1 , wherein the roof panel has a substantially flat surface configured to facilitate mounting of an antenna.

9. A roof assembly for a work vehicle, comprising:
a roof panel comprising:
a vertical peak positioned longitudinally between a forward end and a rearward end of the roof panel;
a forward surface extending from the vertical peak to the forward end of the roof panel, wherein the forward surface is configured to direct water toward the forward end of the roof panel;
a rearward surface extending from the vertical peak to the rearward end of the roof panel, wherein the rearward surface is configured to direct water toward the rearward end of the roof panel; and
a ridge extending around a periphery of the roof panel, wherein the ridge is configured to control water flow from the roof panel, the ridge has a first gap positioned at the rearward end of the roof panel and configured to enable water flow through the ridge, the ridge has a second gap positioned at the forward end of the roof panel and configured to enable water flow through the ridge, and the ridge has a third gap positioned at a first lateral end of the roof panel and configured to enable water flow through the ridge;
wherein the roof panel does not include a channel extending along the roof panel.

10. The roof assembly of claim 9 , wherein the ridge has a fourth gap positioned at the forward end of the roof panel and spaced apart from the second gap along a lateral axis of the roof assembly, and the fourth gap is configured to enable water flow through the ridge.

11. The roof assembly of claim 10 , wherein the ridge has a first curved surface extending from a lateral central portion of the ridge to the second gap, the first curved surface is configured to direct water toward the second gap, the ridge has a second curved surface extending from the lateral central portion of the ridge to the fourth gap, and the second curved surface is configured to direct water toward the fourth gap.

12. The roof assembly of claim 9 , wherein the third gap is positioned on a sloped surface of the roof panel.

13. The roof assembly of claim 9 , wherein the ridge has a fifth gap positioned at a second lateral end of the roof panel, opposite the first lateral end, and the fifth gap is configured to enable water flow through the ridge.

14. The roof assembly of claim 9 , wherein the third gap is configured to be substantially aligned with a door hinge of the work vehicle along a longitudinal axis of the roof assembly to direct water toward the door hinge.

15. The roof assembly of claim 9 , wherein the roof panel has a substantially flat surface configured to facilitate mounting of an antenna.

16. A roof assembly for a work vehicle, comprising:
a roof panel comprising:
a vertical peak positioned longitudinally between a forward end and a rearward end of the roof panel, wherein the roof panel is sloped downwardly from the vertical peak to the forward end of the roof panel to direct water toward the forward end, and the roof panel is sloped downwardly from the vertical peak to the rearward end of the roof panel to direct water toward the rearward end;
a ridge extending around a periphery of the roof panel, wherein the ridge is configured to control water flow from the roof panel, the ridge has a first gap positioned at the rearward end of the roof panel and configured to enable water flow through the ridge, the ridge has a second gap positioned at the forward end of the roof panel and configured to enable water flow through the ridge, and the ridge has a third gap positioned at a first lateral end of the roof panel and configured to enable water flow through the ridge;
wherein the roof panel does not include a channel extending along the roof panel.

17. The roof assembly of claim 16 , wherein the ridge has a fourth gap positioned at the forward end of the roof panel and spaced apart from the second gap along a lateral axis of the roof assembly, and the fourth gap is configured to enable water flow through the ridge.

18. The roof assembly of claim 17 , wherein the ridge has a first curved surface extending from a lateral central portion of the ridge to the second gap, the first curved surface is configured to direct water toward the second gap, the ridge has a second curved surface extending from the lateral central portion of the ridge to the fourth gap, and the second curved surface is configured to direct water toward the fourth gap.

19. The roof assembly of claim 16 , wherein the ridge has a fifth gap positioned at a second lateral end of the roof panel, opposite the first lateral end, and the fifth gap is configured to enable water flow through the ridge.

20. The roof assembly of claim 16 , wherein the third gap is configured to be substantially aligned with a door hinge of the work vehicle along a longitudinal axis of the roof assembly to direct water toward the door hinge.
