String clamping device

Claim 2

A clamping device for clamping the strings of a stringed musical instrument comprising: a base, the base including a plurality of threaded shank elements, and a plurality of spaced stationary clamping plates forming an array extending across and spaced between the strings of the musical instrument when positioned on the musical instrument; a plurality of threaded nuts, each threaded on a respective shank element; and a plurality of actuation means, each interposed between a respective threaded nut and stationary clamping plate for selectively applying clamping pressure to a string positioned between a respective actuation means and stationary clamping plate by engaging and rotating with a respective threaded nut as clamping pressure is applied to the string.

Claim 3

The clamping device of claim 1 wherein each threaded nut includes means for supporting the respective one of the plurality of actuation means.

Claim 4

The clamping device of claim 1 wherein each actuation means is freely rotatable and axially slidable on the respective shank element.

Claim 5

The clamping device of claim 1 wherein each threaded nut and respective actuation means include respective face means for selective frictional engagement with each other.

Claim 6

The clamping device of claim 4 wherein at least one of the face means is a rough surface.

Claim 7

The clamping device of claim 4 wherein each face means includes a generally axial surface.

Claim 8

The clamping device of claim 1 wherein the outer radial surface of each threaded nut is knurled.

Claim 9

The clamping device of claim 1 wherein each actuation means includes a lever portion.

Claim 10

The clamping device of claim 1 wherein the plurality of threaded shank elements constitute portions of a single threaded shank extending through each of the stationary clamping plates.

Claim 11

The clamping device of claim 1 wherein the base includes an integral string nut for the musical instrument.

Claim 12

A clamping device for clamping the strings of a stringed musical instrument comprising: a base, the base including a plurality of threaded shank elements, and a plurality of spaced stationary clamping plates forming an array extending across and spaced between the strings of the musical instrument when positioned on the musical instrument; a plurality of threaded nuts, each threaded on a respective shank element; a plurality of movable clamping plates each in opposed relation to a respective stationary clamping plate, each movable clamping plate freely slidable relative to the threaded shank elements; and a plurality of actuation means, each interposed between a respective threaded nut and movable clamping plate for selectively applying clamping pressure to a respective movable clamping plate by engaging and rotating with a respective threaded nut while rotating relative to a respective movable clamping plate for clamping a string between each of a respective movable clamping plate and a respective stationary clamping plate.

Claim 13

A clamping device for clamping the strings of a stringed musical instrument comprising: a base, the base including a plurality of threaded shank elements, and a plurality of spaced stationary clamping plates forming an array extending across and spaced between the strings of the musical instrument when positioned on the musical instrument; a plurality of threaded nuts, each threaded on a respective shank element; a plurality of movable clamping plates each in opposed relation to a respective stationary clamping plate, each movable clamping plate freely slidable relative to the threaded shank elements; and a plurality of actuation means, each interposed between a respective threaded nut and movable clamping plate for selectively applying clamping pressure to a respective movable clamping plate by engaging and rotating with a respective threaded nut while rotating relative to a respective movable clamping plate for clamping a string between each of a respective movable clamping plate and a respective stationary clamping plate.

Claim 14

The clamping device of claim 11 wherein each movable clamping plate includes means for preventing rotation of the movable clamping plate relative to the base.

Claim 15

The clamping device of claim 11 also including a plurality of stops, and wherein each threaded shank element extends between a respective one of the plurality of stops and a respective one of the plurality of stationary clamping plates, and wherein each respective threaded nut, actuation means and movable clamping plate are interposed between a respective one of the plurality of stops and a respective one of the plurality of stationary clamping plates.

Claim 16

The clamping device of claim 13 wherein each actuation means includes an aperture, and each threaded nut includes a radial surface complementary to the respective aperture for supporting the respective actuation means.

Claim 17

The clamping device of clain 13 wherein each actuation means includes an aperture and each threaded nut includes a step complementary to the respective aperture for supporting the respective actuation means.

Claim 18

The clamping device of clain 13 wherein each actuation means includes an aperture and each threaded nut includes a step complementary to the respective aperture for supporting the respective actuation means.
