Abstract

A finger ( 118 ) for mounting on a of an agricultural harvesting head has a front flange ( 212 ), a rear flange ( 214 ), a web ( 216 ) connecting the front flange ( 212 ) to the rear flange ( 214 ), and struts ( 218 ) that are formed integral with the web ( 216 ) and with the rear flange ( 214 ) and that extend in a transverse direction.

First claim

The invention claimed is:

1. A finger ( 118 ) that is elongate and has a longitudinal extent, for a reel ( 102 ) of an agricultural harvesting head, the reel ( 102 ) having a plurality of bats ( 114 ) disposed about a longitudinal rotational axis ( 116 ), wherein each of the plurality of bats ( 114 ) is configured to support a plurality of the fingers ( 118 ) that are spaced apart and mounted side-by-side on each of the plurality of bats, the finger ( 118 ), as considered in an upright position and facing in a forward direction of travel, comprising:
an upper end configured for being mounted to one of the bats and an elongate upper portion joined to, and extending downwardly from, the upper end, the upper portion being in the form of an I-beam including a front flange ( 212 ) that extends in a longitudinal and a transverse direction, relative to a length of said upper portion;
a rear flange ( 214 ) that extends in the longitudinal and the transverse direction and is spaced apart from the front flange ( 212 );
a web ( 216 ) that extends between the front flange ( 212 ) and the rear flange ( 214 ) and is integrally formed with the front flange ( 212 ) and the rear flange ( 214 ) and wherein a thickness of the web ( 216 ) in the transverse direction is less than the thickness of each of the front flange ( 212 ) and the rear flange ( 214 ) in a fore-and-aft direction; and
struts ( 218 ) that are formed integrally with the web ( 216 ) and with the front flange 212 and the rear flange ( 214 ) and extend in a transverse direction.

2. The finger of claim 1 , wherein adjacent struts ( 218 ) form a triangular box ( 220 ) with the front flange ( 212 ).

3. The finger of claim 1 , wherein adjacent struts ( 218 ) form a triangular box ( 220 ) with the rear flange ( 214 ).

4. The finger of claim 1 , wherein adjacent struts ( 218 ) form a rectangular box ( 222 ) with the front flange ( 212 ) and the rear flange ( 214 ).

5. The finger of claim 1 , wherein adjacent struts ( 218 ) are generally parallel to each other and perpendicular to the front flange ( 212 ) and the rear flange ( 214 ).

6. The finger of claim 1 , wherein the struts ( 218 ) extend in a lateral direction a greater distance adjacent to the rear flange ( 214 ) than adjacent to the front flange ( 212 ).

7. The finger of claim 1 , wherein each adjacent pair of struts ( 218 ) meets at an acute angle at the front flange ( 212 ) and one strut ( 218 f ) of each adjacent pair of struts ( 218 ) extending both upward and rearward from the front flange ( 212 ) to the rear flange ( 214 ), and another strut ( 218 r ) of said adjacent pair of struts ( 218 ) extending both downward and rearward from the front flange ( 212 ) to the rear flange ( 214 ).

8. The finger of claim 7 , wherein the one strut ( 218 f ) of each adjacent pair of struts ( 218 ) meets the another strut ( 218 r ) of a next adjacent pair of struts ( 218 ) at an acute angle at the rear flange ( 214 ), thereby connecting the struts ( 218 ) connected together in a zigzag pattern.

9. The finger of claim 8 , wherein each strut ( 218 ) is disposed at an acute angle with respect to the front flange ( 212 ), and is disposed at an acute angle with respect to the rear flange ( 214 ).

10. The finger of claim 1 , wherein an extent of each of the front flange ( 212 ) and of the rear flange ( 214 ) in the transverse direction is at least three times the thickness of the web ( 216 ) in the transverse direction.

11. The finger of claim 1 , wherein an extent of each of the front flange ( 212 ) and an extent of the rear flange ( 214 ) in the transverse direction is at least four times the thickness of the web ( 216 ) in the transverse direction.
