Abstract

A header bar assembly has a row of header bar elements mounted on a fixed header bar section. The assembly includes a first moveable wing having mounted thereon one or more further header bar elements, the fixed header bar section supporting at the first end a first pillar extending generally perpendicular to the fixed header bar section and via which the first moveable wing is retained moveably captive relative to the fixed header bar section. The first moveable wing is moveable relative to the first pillar vertically and rotatably from an operative, deployed position in which it extends generally parallel to the fixed header bar section to a stowed position through vertical movement on the first pillar and rotation such that the first moveable wing lies adjacent the fixed header bar section inboard of the first pillar.

First claim

The invention claimed is:

1. A header bar assembly comprising
a row of header bar elements mounted on a fixed header bar section; and
a first moveable wing having mounted thereon one or more wing header bar elements,
wherein the fixed header bar section supports at a first end a first pillar extending generally perpendicular to the fixed header bar section and a first eye received over the first pillar and supporting the first moveable wing relative to the fixed header bar section, the first eye and the first moveable wing being moveable relative to the first pillar vertically and rotatably from an operative, deployed position in which the first movable wing is an extension of the fixed header bar section to a stowed position through vertical movement on the first pillar and rotation such that the first moveable wing lies adjacent the fixed header bar section inboard of the first pillar, and
wherein the header bar assembly further comprises a motor mechanically connected to the first eye for rotating and elevating the first eye between the deployed position and the stowed position.

2. The header bar assembly according to claim 1 , further comprising:
at a second end of the fixed header bar section opposite the first end a second moveable wing having mounted thereon one or more header bar elements, the fixed header bar section supporting at the second end a second pillar extending generally perpendicular to the fixed header bar section and a second eye received over the second pillar and supporting the second moveable wing relative to the fixed header bar section, the second eye and the second moveable wing being moveable relative to the second pillar vertically and rotatably from an operative, deployed position in which the second moveable wing is an extension of the fixed header bar section to a stowed position through vertical movement on the second pillar and rotation such that the second moveable wing lies adjacent the fixed header bar section inboard of the second pillar; and
a motor mechanically connected to the second eye for rotating and elevating the second eye between the deployed position and the stowed position.

3. The header bar assembly according to claim 1 , wherein the first movable wing is movable from the stowed position through rotation of the first moveable wing out of parallel with the fixed header bar section before the vertical movement.

4. The header bar assembly according to claim 1 , wherein the first pillar extends vertically upwardly relative to the fixed header bar section.

5. The header bar assembly according to claim 2 , wherein the rotations of the first and second moveable wings are through horizontal arcs.

6. The header bar assembly according to claim 1 , wherein the first moveable wing is moveable from its stowed position to its deployed position through horizontal rotation relative to the associated said first pillar away from the fixed header bar section, vertical movement on the first pillar, and further horizontal rotation such that the first moveable wing lies parallel to the fixed header bar section.

7. The header bar assembly according to claim 1 , further comprising a drive mechanism for causing movement of at least one of the header bar elements and at least one of the one or more wing header bar elements relative to the header bar section, a respective drive coupler/decoupler disengaging the drive mechanism from the at least one of the one or more wing header bar elements upon, during, or before movement of the first moveable wing between the deployed position and the stowed position.

8. The header bar assembly according to claim 7 , wherein the drive coupler/decoupler couples the drive mechanism to the at least one of the one or more wing header bar elements of the first moveable wing when the first moveable wing lies parallel to the fixed header bar section.

9. The header bar assembly according to claim 1 , wherein the row of header bar elements comprises forwardly projecting elements for engaging a crop to be harvested.
