Neck connection for stringed musical instrument
View Patent ↗A stringed musical instrument having, a body portion and a neck connected thereto. The neck connection utilizes a neck block which has an angled surface into which connection bolts are inserted to secure the neck to the body. The angled surface results in offset bolts which resist loosening and provides for an angled force for a more stable connection between the neck and the body.
1. An instrument comprising:
a body having an inside, a top, a bottom and a side wall, which define the inside of the body, the side wall connected to both, and separating, the bottom and the top, wherein the top, the bottom and the side wall form an inner space of the body, the body further comprising a block associated with the side wall, the block having a front surface, a back surface, a top portion and a bottom portion, the block having at least one through hole, the through hole having a longitudinal axis running in the direction of the inner space and extending from the front surface to the back surface, the through hole having at its end an opening on the front surface, the opening defined by a perimeter, wherein the perimeter of the opening on the front surface is on a plane which is off set from a plane which is perpendicular to the longitudinal axis of the through hole,
and
a neck having a first end and a second end, the first end being connected to the block, wherein the first end of the neck faces the back surface of the block, the first end of the neck having at least one hole aligned with the at least one through hole of the block.
2. The instrument of claim 1 , the top portion having a first thickness between the front and back surfaces and the bottom portion having a second thickness between the front and back surfaces, wherein the first thickness is greater than the second thickness.
3. The instrument of claim 1 , wherein the front surface of the block is angled relative to the back surface from the top portion to the bottom surface, wherein the top portion is thicker than the bottom portion.
4. The instrument of claim 1 , wherein the neck is connected to the block via at least one threaded bolt extending through the at least one through hole in the block and into the at least one hole of the first end of the neck.
5. The instrument of claim 4 , wherein there are two through holes extending from the front surface to the back surface and the first end of the neck having two holes aligned with the two through holes of the block, wherein the neck is connected to the block via two threaded bolts extending through the block, each in a separate through hole, and into the corresponding holes of the first end of the neck and wherein each through hole having a longitudinal axis running in the direction of the inner space and extending from the front surface to the back surface, each through holes having at its end opening on the front surface, the opening defined by a perimeter, wherein the perimeter of the opening on the front surface is on a plane which is off set from a plane which is perpendicular to the longitudinal axis of the through hole.
6. The instrument of claim 5 , wherein the front surface is substantially off set relative to the back surface.
7. The instrument of claim 5 , wherein a portion of the sidewall is between the block and the first end of the neck.
8. The instrument of claim 5 , wherein the first end of the neck comprises a tongue and a connecting brace, the tongue and the connection brace being generally perpendicular to one another, wherein the tongue extends over the top of the body and the connection brace faces the back surface of the block and wherein the two holes of the neck are in the connection brace.
9. The instrument of claim 8 , wherein the through holes of the block and the holes in the neck are substantially perpendicular to the back surface of the block and the sidewall.
10. The instrument of claim 9 , the tongue and the connection brace forming an inner corner, wherein the bolts, when tightened, urge a portion of the body into the inner corner.
11. The instrument of claim 1 , wherein the neck is connected to the block via a threaded bolt having a head, the bolt being screwed into the through hole such that the head of the bold is urged against the perimeter of the opening.
