Abstract

Abstract The invention is for an instrument carrying case comprising an open-topped box, a lid having a substantially planar panel for covering the top of the box, and a flexible hinge joining the rear edge of the lid to the top edge of the rear wall of the box such that the lid is movable through an angle of about 270° from a position at which its panel covers the box to an "inside-out" position for the lid at which such panel is adjacent and substantially parallel to the outside of the rear wall of the box, and in which the normally forward part of the lid projects laterally beyond the bottom of the box. The case further comprises a fastening means for securing the box and the lid together when the latter is in such inside-out position.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 442 words
A carrying case for an electrical instrument comprising, an open topped box having a bottom, a front wall, a rear wall and a pair of side walls, said side walls being about three times longer than the height of said rear wall, and the width of said front and rear walls being about twice greater than said height, a lid having a rectangular top panel having a length and width approximating that of, respectively, said side walls and said rear wall, and having, also, respectively, said side walls and said rear wall, and having, also, side flanges depending from the side edges of said panel, said lid being adapted to fit over and close the top of the box with said flanges being on the outside of, and overlapping with, the corresponding walls of said box, all said elements of said box and lid being relatively rigid and having a laminated structure comprising an inner layer of stiff material and an outer layer of flexible material, a flexible hinge joining the top edge of said rear wall of said box to the rear edge of said panel of said lid, said hinge being provided by a strip of said flexible material constituting a portion longitudinally central of, and transversely extending across a sheet of said flexible material providing on longitudinally opposite sides of said strip the flexible material of the laminated structure of, respectively, said rear wall and said panel, said hinge enabling said lid to be swung about 270 degrees thereabout from its box closing position to an inside out position at which the normal outside of said panel is adjacent and substantially parallel to the rear wall of said box, fastening means comprising mutually engageable parts carried by, respectively, said rear wall and said panel and adapted by engagement of said parts to releasably fasten said panel in said inside-out portion to the rear of said box so as to provide a prop raising said rear when said box and lid are placed on a horizontal support surface, and a pair of eyelets formed at a longitudinally central location in the bottom of said box along the longitudinally centerline thereof in longitudinally spaced relation from each other, said eyelets being adapted, in conjunction with a screw passed through either thereof into a hole formed in the bottom of such an instrument to be centrally located in the width thereof, to provide instrument securing means enabling such instrument to be secured to the bottom of said box either inside or outside such bottom, and forwardly or reversely in relation thereto, and, in all such cases, in centered relation with such bottom.
Claim 2
