Abstract
Abstract A case for a stringed musical instrument has its enclosure or body in the form of a right triangular prism to present spaced apart parallel panels with right triangular perimeters and a peripheral wall extending between such perimeters of the panels and having right angularly related portions with contiguous ends, and preferably of different lengths, and a diagonal portion extending between the other ends, and the carrying handle extends from the peripheral wall at a location between the ends of the diagonal portion which is selected so that with the longer of the right angularly related portions of the peripheral wall extending substantially vertical, the handle will be substantially in vertical alignment with the center of gravity of the case with the instrument therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
A case for a stringed musical instrument; comprising an enclosure including spaced apart, substantially parallel panels with right triangular perimeters and a peripheral wall extending between said perimeters of the panels and having right angularly related portions with contiguous ends and a diagonal portion joined at its ends with the other ends of said right angularly related portions, each of said triangular perimeters having sides of unequal lengths so that said right angularly related portions of the peripheral wall are similarly of unequal lengths, and a carrying handle joined to said peripheral wall at a location which is disposed along said diagonal portion and spaced from said ends of the latter so that, with the longer of said right angularly related portions extending substantially vertical, a vertical line through the center of gravity of the case with an instrument therein passes substantially through said handle.
Claim 2
Dependent Claim
145 words
A case for a stringed musical instrument; comprising an enclosure including spaced apart, substantially parallel panels with right triangular perimeters and a peripheral wall extending between said perimeters of the panels and having right angularly related portions with contiguous ends and a diagonal portion joined at its ends with the other ends of said right angularly related portions, each of said triangular perimeters having sides of unequal lengths so that said right angularly related portions of the peripheral wall are similarly of unequal lengths, and a carrying handle joined to said peripheral wall at a location which is disposed along said diagonal portion and spaced from said ends of the latter so that, with the longer of said right angularly related portions extending substantially vertical, a vertical line through the center of gravity of the case with an instrument therein passes substantially through said handle.
Claim 3
Dependent Claim
38 words
A case for a stringed musical instrument according to claim 1; in which at least the shorter of said right angularly related portions of the peripheral wall is substantially flat so that said enclosure can stand erect thereon.
Claim 4
Dependent Claim
55 words
A case for a stringed musical instrument according to claim 2; in which said peripheral wall is joined integrally to one of said panels at said perimeter of the latter, and the other of said panels forms a lid which is hingedly connected to said peripheral wall at one of said portions of the latter.
Claim 5
Dependent Claim
36 words
A case for a stringed musical instrument according to claim 1; in which said carrying handle extends fron said diagonal portion substantially parallel with the shorter of said right angularly related portions of the peripheral wall.
