Harvesting Tool

Abstract

A paddle tine for use over a pickup tine previously fixed with a harvester reel tube of a harvesting header comprises an elongated body having a central cavity therethrough and is adapted to slide over the pickup tine of the harvester reel tube. An attachment mechanism, such as one or more resilient clips with a fastening clip, is fixed with the proximal end of the elongated body to secure the paddle tine to the harvester reel tube over the pickup tine. Two opposing paddle webs project laterally away from the elongated body proximate the distal end.

Claims

1. A paddle tine for use with a pickup tine fixed with a harvester reel tube, comprising: an elongated body having a central cavity therethrough from a proximal end to proximate a distal end, the elongated body adapted to slide over the pickup tine of the harvester reel tube, the central cavity being only open at ends thereof, enclosing the pickup tine therein; and an attachment mechanism fixed with the proximal end of the elongated body; the attachment mechanism including one or more resilient clips fixed with opposing sides of the proximal end of the elongated body, each clip having at least one retaining ledge oriented facing substantially towards the distal end of the elongated body; the attachment mechanism including a fastener clip adapted to encompass the harvester reel tube and at least a portion of the resilient clips, the fastener clip having inwardly-projecting flanges adapted to engage and hold the retaining ledges of the resilient clips; whereby the paddle tine may be slid over the pickup tine and secured to the harvester reel tube by securing the retention clip about the harvester reel tube, the fastener clip then being fastened over the harvester reel tube and the resilient clips of the proximal end of the elongated body to secure the paddle tine to the harvester reel tube.

2. The paddle tine of claim 1 wherein the distal end of the elongated body further includes two opposing paddle webs projecting laterally away from the elongated body proximate the distal end;

3. The paddle tine of claim 1 wherein the elongated body is arced from the distal end to the proximal end when looking at the elongated body from either side.

4. The paddle tine of claim 1 wherein front and rear sides of the elongated body proximate the proximal each include a longitudinally-aligned notch.

5. The paddle tine of claim 2 wherein each of the two opposing paddle webs include a reinforced bottom portion having a thickness greater than a web portion thereof.

6. The paddle tine of claim 1 wherein a distal side of the resilient clips each include a smooth outer surface from the retaining ledge to the proximal end of the elongated body, whereby the inwardly-projecting flanges of the fastening clip contact the smooth outer surface to separate the inwardly-projecting flanges mutually apart as the fastening clip engages the resilient clips, whereby once the inwardly-projecting flanges clear the retaining ledges the inwardly-projecting flanges snap back towards each other to engage the retaining ledges.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0020] Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

[0021] FIGS. 1 and 2 illustrate a paddle tine 10 for use with a pickup tine 16 fixed with a harvester reel tube 15 of a harvesting header or other machine (not shown). The paddle tine 10 comprises an elongated, rigid body 20 having a central cavity 25 therethrough from a proximal end 22 to proximate a distal end 28 thereof. The elongated body 20 is adapted to slide over the pickup tine 16 of the harvester reel tube 15 (FIG. 4). As most pickup tines 16 are curved or arched, preferably the elongated body 20 is arched from the distal end 28 to the proximal end 22 from a side view (FIG. 4). A front side 21 of the elongated body 20 forms a concave face 24 (FIGS. 3 and 4). The front side 21 and rear side 29 preferably each include a longitudinally-aligned notch 50 for receiving therein portions of the pickup tine 16. Preferably the elongated body 20 is made from a rigid injection-molded plastic material.

[0022] An attachment mechanism 30 is fixed with the proximal end 22 of the elongated body 20. Preferably the attachment mechanism 30 includes one or more resilient clips 31 (FIGS. 1, 3 and 4). In some embodiments each resilient clip 31 includes a relatively resilient inner portion 36 fixed within a relatively rigid outer portion 35, the resilient inner portion 36 accommodating a shoulder of the pickup tine 16.

[0023] In some embodiments, the attachment mechanism 30 includes a pair of loops 32 (FIG. 2) projecting away from each of the clips 31, such that the paddle tine 10 may be slid over the pickup tine 16 and secured to the harvester reel tube 15 with the resilient clips 31, a pair of plastic, resilient fastening ties 33 being threaded through each of the loops 32 and about the harvester reel tube 15 to further secure the paddle tine 10 to the harvester reel tube 15. In some embodiments the fastening ties 33 are replaced with hook-and-loop fastening strips 34. In some embodiments the fastening ties 33 or hook-and-loop fastening strips 34 are applied to embodiments of the paddle tine devoid of the loops 32 (not shown), and simply fasten around the resilient clips 31.

[0024] Two opposing paddle webs 40 project laterally away from the elongated body 20 proximate the distal end 28. Preferably each of the two opposing paddle webs 40 includes a reinforced bottom portion 41 having a thickness greater than a web portion 42 thereof (FIGS. 1 and 3).

[0025] In some embodiments, the attachment mechanism 30 includes at least one retaining ledge 37 (FIGS. 5A-6) formed as part of each resilient clip 31. Such a retaining ledge 37 preferably is oriented facing substantially towards the distal end 28 of the elongated body 20. A fastener clip 60 is further included for encompassing the harvest reel tube 15 and at least a portion of the resilient clips 31. The fastener clip 60 has inwardly-projecting flanges 65 and is resilient, such that the retention clip 31 may be secured over the harvest reel tube 15 and the resilient clips 31 of the proximal end 22 of the elongated body 20 to secure the paddle tine 10 to the harvester reel tube 15.

[0026] Preferably in such embodiments a distal side of the resilient clips 31 each include a smooth outer surface 38 (FIG. 5A) from the retaining ledge 37 to the proximal end 22 of the elongated body 20, such that the inwardly-projecting flanges 65 of the fastening clip 60 contact the smooth outer surface 38 to separate the inwardly-projecting flanges 65 apart as the resilient fastening clip 60 engages the resilient clips 31. Once the inwardly-projecting flanges 65 clear the retaining ledges 37 the inwardly-projecting flanges 65 snap back toward each other to engage the retaining ledges 37 and maintain the elongated body 20 on the harvester reel tube 15. Further, each resilient clip 31 preferably includes an outer lip 39 to laterally retain the resilient fastening clip 60 thereon.
