Abstract
An improved piano tuning lever includes a handle with a loop or ring large enough to fit the fingers of a user's hand, thereby providing a grip around the perimeter of the loop or ring which is independent of the axis of the handle. The resulting grip affords improved ergonomics and may lessen stress in the user's wrist and hand when having to conform to various angles of the handle axis as the tuning lever is moved from tuning pin to tuning pin over the course of a piano tuning. The improved handle and loop or ring may be made any size or shape, symmetrical or asymmetrical and with its core being solid, hollow, or filled. Another embodiment of the piano tuning lever includes a spline designed to mate with an inventive piano tuning lever head having complementary splines.
Claims20
A musical instrument tuning lever kit comprising
- a handle having
- a loop portion at a proximal end,
- a stem portion extending along a first axis from said loop portion to a distal end, and
- an axially extending aperture at said distal end,
- a shaft component
- extending along a second axis and receivable within said aperture of said stem portion of said handle and
- having means for attachment of a head component,
- said head component having
- at a first end complementary means for attachment to said shaft component and
- at a second end means for attachment of a tip component,
- said tip component having
- a first end comprising complementary means for attachment to said head component, and
- a second end comprising a socket aperture extending along a third axis for engagement with a tuning pin.
A musical instrument tuning lever kit comprising
- a handle having
- a loop portion at a proximal end,
- a stem portion extending along a first axis from said loop portion to a distal end, and
- an axially extending aperture at said distal end,
- a ferrule component,
- a shaft component
- extending along a second axis and
- receivable within said ferrule component and
- having means for attachment of a head component,
- said head component having
- a first end comprising complementary means for attachment to said shaft component and
- a second end comprising means for attachment of a tip component,
- said tip component having
- a first end comprising complementary means for attachment to said head component and
- a second end comprising a socket aperture extending along a third axis for engagement with
- a tuning pin.
A musical instrument tuning lever assembly, comprising
- a handle having a loop portion at a proximal end defining a first plane, a stem portion extending along a first axis from said loop portion to a distal end, and an axially extending aperture at said distal end,
- a tip component comprising
- a first end having a shaft portion receivable within said handle aperture and extending along a second axis, and
- a second end comprising a socket aperture extending along a third axis for engagement with a tuning pin, whereby said second and third axis define a second plane orientable at an angle to said first plane, and
- a collet nut threadably coupled to said stem portion of said handle to secure said tip component within said axially extending aperture of said handle.
