Total Claims: 14
Claim 1
Independent Claim
110 words
A guitar provided with a body, a neck connected to said body, and a fingerboard disposed upon said neck, means for fastening said neck to said body, said guitar body being formed partially solid from moldable material, in which said guitar body includes a plurality of hollow areas separated by upstanding ribs, and wherein said guitar body is formed from a top and bottom section defining a clam shell type of structure, guide means are provided between said top and bottom sections to facilitate alignment of the respective portions and at least some of said hollow areas contain foam of selected densities to control the resonance of the guitar body.
Claim 2
Dependent Claim
110 words
A guitar provided with a body, a neck connected to said body, and a fingerboard disposed upon said neck, means for fastening said neck to said body, said guitar body being formed partially solid from moldable material, in which said guitar body includes a plurality of hollow areas separated by upstanding ribs, and wherein said guitar body is formed from a top and bottom section defining a clam shell type of structure, guide means are provided between said top and bottom sections to facilitate alignment of the respective portions and at least some of said hollow areas contain foam of selected densities to control the resonance of the guitar body.
Claim 3
Dependent Claim
89 words
The device of claim 1 in which said neck is provided with a central channel having varying depths disposed along its longitudinal extent, and a torsion rod is disposed therein, and said finger board comprises a top portion adapted to overlie the top of said neck, and a medially downwardly disposed web which resides within said channel in juxtaposition with said torsion rod so as to provide a link between said torsion rod and said finger board for adjusting and compensating for stresses imposed by strings on a guitar.
Claim 4
Dependent Claim
47 words
The device of claim 2 in which said finger board is provided with integral frets parallelly oriented to each other and orthogonally disposed relative to the longitudinal axis of said finger board, and further including a nut at a terminal portion thereof for orienting the strings thereover.
Claim 5
Dependent Claim
22 words
The device of claim 3 in which position markers are provided within said fingerboard through means defining openings on said finger board.
Claim 6
Dependent Claim
60 words
The device of claim 4 in which position markers are provided within said finger board through means defining openings on said finger board, and said position markers include a cylindrical solid fashioned to reside within said opening, having a semicylindrical extension disposed on a bottom edge thereof, said semicylindrical extension traversing from said finger board to an outer edge thereof.
Claim 7
Dependent Claim
40 words
The device of claim 1 in which a molding trim is disposed around an outer periphery of the guitar body along a seam between said top and bottom sections and wherein said top and bottom sections are injected molding elements.
Claim 8
Dependent Claim
60 words
The device of claim 6 in which said molding is defined by a depending flap portion which extends from said top section of the guitar body, and terminates thereafter into a stem portion, which supports a triangular wedge adapted to nest within corresponding grooves on said top and bottom sections of said guitar body so as to be affixed thereto.
Claim 9
Dependent Claim
47 words
The device of claim 7 in which said wedge coacts against a region along said bottom section of the guitar body and through a lip downwardly extending from said top section which tends to secure the bottom portion of the guitar between said wedge and said lip.
Claim 10
Dependent Claim
22 words
The device of claim 8 in which said molding is fastened to said top and bottom sections by means of an adhesive.
Claim 11
Dependent Claim
