Abstract
An adjustable neck joint for a stringed instrument includes a neck with a heel portion formed as a first half of a rotating joint and a body with a neck block formed as a second half of the rotating joint. The first half of the rotating joint and the second half of the rotating joint may each be configured to connect with the other and movably interface with each other such that the neck is rotatable with respect to the body about an axis located immediately adjacent to and above a position along the neck.
Claims18
An adjustable neck joint for a stringed instrument comprising:
- a neck with a heel portion formed as a first half of a rotating joint;
- and
- a neck block formed as a second half of the rotating joint;
- wherein
- the first half of the rotating joint and the second half of the rotating joint are each configured to connect with each other and movably interface with each other such that the neck is rotatable with respect to the neck block about an axis perpendicular to a longitudinal axis of the neck;
- the first half of the rotating joint is one of an arcuate mortise or an arcuate tenon structure;
- and
- the second half of the rotating joint is an opposing one of the arcuate mortise or arcuate tenon structure to the first half of the rotating joint.
A stringed instrument comprising:
- a neck with a heel portion formed as a first half of a rotating joint;
- and
- a body with a neck block formed as a second half of the rotating joint;
- wherein
- the first half of the rotating joint and the second half of the rotating joint are each configured to connect with each other and movably interface with each other such that the neck is rotatable with respect to the body about an axis perpendicular to a longitudinal axis of the neck;
- the first half of the rotating joint is one of an arcuate mortise or an arcuate tenon structure;
- and
- the second half of the rotating joint is an opposing one of the arcuate mortise or arcuate tenon structure to the first half of the rotating joint.
A method for adjusting an action of a stringed instrument, wherein the stringed instrument comprises:
- a neck with a heel portion formed as a first half of a rotating joint;
- a body with a neck block formed as a second half of the rotating joint, wherein:
- the first half of the rotating joint and the second half of the rotating joint are each configured to connect with each other and movably interface with each other such that the neck is rotatable with respect to the body about an axis perpendicular to a longitudinal axis of the neck;
- the first half of the rotating joint is one of an arcuate mortise or an arcuate tenon structure;
- and
- the second half of the rotating joint is an opposing one of the arcuate mortise or arcuate tenon structure to the first half of the rotating joint;
- and
- an adjustment mechanism attached at a first end to the heel portion in the first half of the rotating joint and constrained with respect to the neck block at a second end;
- wherein
- the method comprises operating the adjustment mechanism to finely move the heel portion with respect to the neck block within the rotating joint through an angle of at least one degree, the angle having a vertex located on the axis, such that the a surface of the neck is movable toward and away from strings of the stringed instrument while the strings remain in tune.
