Summary for Patent: 8,210,969

Title:	Ergonomic sports handle
Abstract:	A sports utility handle is provided for use with a sports equipment shaft including an upper shaft surface having an upper shaft plane, a lower shaft surface having a lower shaft plane, two side shaft surfaces having side surface planes and a shaft centerline. The handle includes a shaft engagement end, a handle termination end opposite thereto, an upper handle surface, a lower handle surface comprising a lower surface spline extending inwards from the lower shaft plane towards the upper shaft plane in a first lower handle surface beginning at the shaft engagement end. The lower surface spline extending outwards in the lower shaft plane direction in a second lower handle surface beginning at the first lower handle surface and extending towards the handle termination end. A curved stop element runs between the upper handle surface towards the lower handle surface at the handle termination end and is sized to fit within a human palm. Two handle side surfaces run generally parallel to the two side shaft surfaces. The lower surface spline is configured to provide a relaxed wrist grip such that the shaft centerline is generally aligned with a user forearm centerline.

Patent Claims:	1. A sports utility handle for use with sports equipment shaft including an upper shaft surface having an upper shaft plane, a lower shaft surface having a lower shaft plane, two side shaft surfaces having side surface planes, a shaft depth and a shaft centerline, the sports utility handle comprising: a shaft engagement end; a handle termination end opposite said shaft engagement end; a upper handle surface; a lower handle surface comprising a lower surface spline, said lower surface spline extending inwards in the direction of the lower shaft plane towards an upper surface plane in a first lower handle surface portion beginning at said shaft engagement end, said lower surface spline extending outwards in a direction back towards the lower shaft plane in a second lower handle surface portion beginning at said first lower handle surface portion and extending towards said handle termination end; a rounded downward protrusion portion running between said upper handle surface towards said lower handle surface at said handle termination end; and two handle side surfaces running generally parallel to the two side shaft surfaces; wherein said lower surface spline is configured to provide an ergonomic wrist grip such that the shaft centerline is generally aligned with a user forearm centerline. 2. The sports utility handle according to claim 1 further comprising: an upper surface spline extending from the upper shaft plane in a direction away from the lower shaft plane in a first upper handle surface portion and extending back in the upper shaft plane direction in a second upper handle surface portion. 3. The sports utility handle according to claim 1 wherein: said rounded downward protrusion portion configured to point generally in a lower shaft plane direction, said rounded downward protrusion protruding past the lower shaft plane for a distance less than the shaft depth. 4. The sports utility handle according to claim 1 wherein said shaft engagement end is integrated into a tennis racket. 5. The sports utility handle according to claim 1 wherein said rounded downward protrusion portion is sized to fit within a human palm. 6. The sports utility handle according to claim 1 wherein said lower surface spline is configured to generate a wrist rotation of less than 20 degrees when gripped. 7. The sports utility handle according to claim 1 wherein second lower handle surface portion generates a palm centre at or above the lower shaft plane. 8. The sports utility handle according to claim 1 wherein said lower surface spline is configured to generate a related wrist grip angle less than 30 degrees and a palm centre less than 0.5 inches below the shaft centerline. 9. The sports utility handle according to claim 1, wherein said first lower handle surface portion includes an initial downward bulge. 10. An piece of sports equipment comprising: a sports equipment shaft including an upper shaft surface having an upper shaft plane; a lower shaft surface having a lower shaft plane, said upper shaft plane and said lower shaft plane defining a shaft depth; two side shaft surfaces having side surface planes; a shaft centerline; and an ergonomic handle comprising: a shaft engagement end; a handle termination end opposite said shaft engagement end; an upper handle surface; a lower handle surface comprising a lower surface spline, said lower surface spline extending inwards from the lower shaft plane towards an upper surface plane in a first lower handle surface beginning at said shaft engagement end, said lower surface spline extending outwards in the lower shaft plane direction in a second lower handle surface beginning at said first lower handle surface and extending towards said handle termination end; a rounded downward protrusion running between said upper handle surface towards said lower handle surface at said handle termination end; and two handle side surfaces running generally parallel to the two side shaft surfaces; wherein said second handle surface portion is configured to provide a relaxed wrist grip and forearm centerline approximately parallel to said shaft centerline, and said first handle surface portion is configured to raise said user forearm centerline until it is approximately coincident with said shaft centerline. 11. The piece of sports equipment according to claim 10 further comprising: an upper surface spline extending from the upper shaft plane in a direction away from the lower shaft plane in a first upper handle surface portion and extending back in the upper shaft plane direction in a second upper handle surface portion. 12. The piece of sports equipment according to claim 10, wherein said sports equipment shaft comprises a tennis racket shaft. 13. The piece of sports equipment according to claim 10, wherein said sports equipment shaft comprises a fishing rod shaft. 14. The piece of sports equipment according to claim 10, wherein said sports equipment shaft comprises a baseball bat shaft. 15. The piece of sports equipment according to claim 10, wherein said sports equipment shaft comprises a golf club shaft. 16. The piece of sports equipment according to claim 10, wherein said sports equipment shaft comprises a lacrosse stick shaft. 17. An piece of sports equipment comprising: a sports equipment shaft including an upper shaft surface having an upper shaft plane; a lower shaft surface having a lower shaft plane, said upper shaft plane and said lower shaft plane defining a shaft depth; two side shaft surfaces having side surface planes; a shaft centerline; and an ergonomic handle comprising: a shaft engagement end; a handle termination end opposite said shaft engagement end; an upper handle surface; a lower handle surface comprising a lower surface spline, said lower surface spline extending inwards from the lower shaft plane towards an upper surface plane in a first lower handle surface beginning at said shaft engagement end, said lower surface spline extending outwards in the lower shaft plane direction in a second lower handle surface beginning at said first lower handle surface and extending towards said handle termination end; a rounded downward protrusion running in a constant downward direction between said upper handle surface and said lower handle surface at said handle teimination end; and two handle side surfaces running generally parallel to the two side shaft surfaces; wherein said second handle surface portion is configured to provide a relaxed wrist grip and forearm centerline approximately parallel to said shaft centerline, said rounded downward protrusion configured to be contained within a users palm when said relaxed wrist grip is achieved and said forearm centerline is parallel to said shaft centerline, and said first handle surface portion is configured to raise said user forearm centerline until it is approximately coincident with said shaft centerline while maintaining a wrist rotation of less than 30 degrees.
