Oar Snubber

Abstract

The Oar Snubber is a device to prevent a rower from falling out of a whitewater rowing vessel when using oars and oar locks. The device prevents an oar shaft from sliding out of its oarlock when extreme angles are encountered in whitewater conditions without limiting the rotational movement of the oar blade. It performs as a rotational retention device with adjustable but limited lateral movement.

Claims

1. An Oar Snubber comprising of a clamp and shock cord retention strap.

2. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 1, wherein the clamp has a 3.8-inch diameter, 3-D printed thermoplastic ring which is 0.8-inch thick by 0.8-inch width and has a print-in-place hinge at zero degrees along its circumference and a 0.1-inch offset notch opposing the hinge.

3. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 2, wherein the offset notch acts as the point of securement and the contact point for the elastic shock cord.

4. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 1, wherein the clamp uses a stainless-steel bolt and nut to secure it in place and retain the loop of webbing connected to the elastic shock cord.

5. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 2, wherein hinge can open approximately 80 degrees but less than 90 degrees, allowing the device to be placed around the oar shaft.

6. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 1, wherein the internal circumferential surface is patterned with a raised notched coil which grips on to the rope wrap of an oar's shaft.

7. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 1, wherein the shock cord retention strap has a clamp end and a frame end and is comprised of six individual components.

8. The Oar Snubber comprising of the clamp and shock cord retention strap as in claim 7, wherein the components for the shock cord retention strap are 0.75-inch Polypropylene webbing loops stitched to both ends of the shock cord, a 3/16-inch triple looped marine grade shock cord which is 7 inches in length, a 1-inch tubular polypropylene webbing encapsulating the shock cord which is 12 inches in length, an adhesive back industrial-strength, heat shrink wrap, a 0.75-inch Side Release Buckle Dual Adjustable buckle-metal female, with a plastic male portion, and a bar tacked loop of 0.75-inch polypropylene webbing.

9. A method of manufacturing an Oar Snubber comprising of a clamp and shock cord retention strap.

10. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 9, wherein the clamp has a 3.8-inch diameter, 3-D printed thermoplastic ring which is 0.8-inch thick by 0.8-inch width and has a print-in-place hinge at zero degrees along its circumference and a 0.1-inch offset notch opposing the hinge.

11. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 10, wherein the offset notch acts as the point of securement and the contact point for the elastic shock cord.

12. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 9, wherein the clamp uses a stainless-steel bolt and nut to secure it in place and retain the loop of webbing connected to the elastic shock cord.

13. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 10, wherein hinge can open approximately 80 degrees but less than 90 degrees, allowing the device to be placed around the oar shaft.

14. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 9, wherein the internal circumferential surface is patterned with a raised notched coil which grips on to the rope wrap of an oar's shaft.

15. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 9, wherein the shock cord retention strap has a clamp end and a frame end and is comprised of six individual components.

16. The method of manufacturing the Oar Snubber comprising of a clamp and shock cord retention strap as in claim 15, wherein the components for the shock cord retention strap are 0.75-inch Polypropylene webbing loops stitched to both ends of the shock cord, a 3/16-inch triple looped marine grade shock cord which is 7 inches in length, a 1-inch tubular polypropylene webbing encapsulating the shock cord which is 12 inches in length, an adhesive back industrial-strength, heat shrink wrap, a 0.75-inch Side Release Buckle Dual Adjustable buckle-metal female, with a plastic male portion, and a bar tacked loop of 0.75-inch polypropylene webbing.
