Abstract

A conveyor joint assembly (600) is provided including a support ledge (501) operably coupled to and extending from a first sealing surface (602), a first side wall and second side wall (507) operably coupled to opposite ends of the support ledge (501), a receiver (504) operably coupled to the first sealing surface (602), and at least one protrusion (503) operably coupled to a second sealing surface (604). The second sealing surface (604) is configured to engage the support ledge (501) and the receiver (504) is configured to retain the at least one protrusion (503) causing the first sealing surface (602) to engage the second sealing surface (604).

First claim

That which is claimed:

1. A conveyor joint assembly comprising:
a support ledge operably coupled to and extending from a first sealing surface,
a first side wall and second side wall operably coupled to opposite ends of the support ledge;
a receiver operably coupled to the first sealing surface;
at least one protrusion operably coupled to a second sealing surface; and
a hood operably coupled to a receiving end of the conveyor,
wherein the second sealing surface is configured to engage the support ledge and the receiver is configured to retain the at least one protrusion causing the first sealing surface to engage the second sealing surface,
wherein the hood comprises the second sealing surface, and
wherein the hood further comprises a biasing element configured to bias the second sealing surface toward the first sealing surface.

2. The conveyor joint assembly of claim 1 , wherein the first sealing surface is operably coupled to a working deck of a yard care vehicle, and the second sealing surface is operably coupled to a conveyor.

3. The conveyor joint assembly of claim 1 , wherein the at least one protrusion is disposed in a first half of the second sealing surface and the receiver is disposed in a first half of the first sealing surface, and
wherein a width of the first sealing surface and second sealing surface is at least 50 percent wider in a respective second half than the width of the first sealing surface and second sealing surface in the respective first half, enabling axial rotation of the conveyer joint while maintaining engagement of the first sealing surface and the second sealing surface.

4. The conveyor joint assembly of claim 3 , wherein the second sealing surface further comprises an engagement member configured to retain the second half of the second sealing surface in contact with the first sealing surface,
wherein the engagement member enables the first sealing surface and second sealing surface to pivot while maintaining contact.

5. The conveyor joint assembly of claim 4 , wherein the engagement member comprises a hook configured to extend from the second sealing surface and around at least a portion of the first sealing surface.

6. The conveyor joint assembly of claim 1 further comprising a resilient material operably coupled to the first sealing surface or second sealing surface to increase engagement of the first sealing surface with the second sealing surface.

7. A conveyor joint assembly comprising:
a support ledge operably coupled to and extending from a first sealing surface,
a first side wall and second side wall operably coupled to opposite ends of the support ledge;
a receiver operably coupled to the first sealing surface;
at least one protrusion operably coupled to a second sealing surface; and
a hood operably coupled to a receiving end of the conveyor,
wherein the second sealing surface is configured to engage the support ledge and the receiver is configured to retain the at least one protrusion causing the first sealing surface to engage the second sealing surface,
wherein the hood comprises the second sealing surface, and
wherein the hood is pivotably coupled to the receiving end of the conveyor by the at least one protrusion.

8. A conveyor joint assembly comprising:
a support ledge operably coupled to and extending from a first sealing surface,
a first side wall and second side wall operably coupled to opposite ends of the support ledge;
a receiver operably coupled to the first sealing surface;
at least one protrusion operably coupled to a second sealing surface; and
a hood operably coupled to a receiving end of the conveyor,
a conveyor lift assembly configured to lift the conveyor vertically a predetermined distance causing the conveyor to move to a disengaged position, wherein moving to the disengaged position comprises the at least one protrusion to disengaging the receiver,
wherein the second sealing surface is configured to engage the support ledge and the receiver is configured to retain the at least one protrusion causing the first sealing surface to engage the second sealing surface, and
wherein the hood comprises the second sealing surface.

9. The conveyor joint assembly of claim 8 , wherein the first sealing surface is operably coupled to a working deck, and
wherein the working deck is pivotable between a cutting position and a service position when the conveyor is in the disengaged position.

10. The conveyor joint assembly of claim 9 , wherein the cutting deck is configured to be locked in the service position by a service lock.

11. The conveyor joint assembly of claim 8 , wherein transitioning the cutting deck to the service position requires only a lever tool configured to release a front cover of the cutting deck.

12. A lawn care vehicle comprising:
a conveyor joint assembly comprising:
a support ledge operably coupled to and extending from a first sealing surface,
a first side wall and second side wall operably coupled to opposite ends of the support ledge;
a receiver operably coupled to the first sealing surface; and
at least one protrusion operably coupled to a second sealing surface,

wherein the at least one protrusion is disposed in a first half of the second sealing surface and the receiver is disposed in a first half of the first sealing surface,
wherein a width of the first sealing surface and second sealing surface is at least 50 percent wider in a respective second half than the width of the first sealing surface and second sealing surface in the respective first half, enabling axial rotation of the conveyer joint while maintaining engagement of the first sealing surface and the second sealing surface, and
wherein the second sealing surface is configured to engage the support ledge and the receiver is configured to retain the at least one protrusion causing the first sealing surface to engage the second sealing surface.

13. The lawn care vehicle of claim 12 , further comprising a resilient material operably coupled to the first sealing surface or second sealing surface to increase engagement of the first sealing surface with the second sealing surface, and
wherein the first sealing surface is operably coupled to a working deck of a yard care vehicle, and the second sealing surface is operably coupled to a conveyor.

14. The lawn care vehicle of claim 12 wherein the conveyor joint assembly further comprises:
a hood operably coupled to a receiving end of the conveyor, and
wherein the hood comprises the second sealing surface.

15. The lawn care vehicle of claim 14 , wherein the hood is pivotably coupled to the receiving end of the conveyor by the at least one protrusion, or
wherein the hood further comprises a biasing element configured to bias the second sealing surface toward the first sealing surface.

16. The lawn care vehicle of claim 14 , wherein the conveyor joint assembly further comprises:
a conveyor lift assembly configured to lift the conveyor vertically a predetermined distance causing the conveyor to move to a disengaged position, wherein moving to the disengaged position comprises the at least one protrusion to disengaging the receiver.

17. The lawn care vehicle of claim 16 , wherein the first sealing surface is operably coupled to a working deck,
wherein the working deck is pivotable between a cutting position and a service position when the conveyor is in the disengaged position, and
wherein the cutting deck is configured to be locked in the service position by a service lock.
