Abstract

Abstract A trough-like container for holding a high powered generator unit of electronic photoflash apparatus, useful especially in studio photography or in commercial or industrial photography, where it is desirable to have a power unit of considerably greater power capacity than those normally used in amateur photography. For holding a high power generator of this kind, it is important to have a carrying case which is light, sturdy with respect to external blows or knocks, readily transportable, shock proof and safe so far as electrical hazards are concerned, and as compact as possible with relation to the volume of the electrical generator equipment to be contained therein. The present container is formed of foamed plastic material having a metal bearing ring integrally molded within the trough-like container near the top thereof, the ring having bore-holes for attaching the electronic flash generator carried within the container, as well as for attaching a carrying strap.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 95 words
A container for a portable high voltage electronic flash power unit comprising a hollow body having side walls of foamed plastic material, a metallic bearing ring extending along said side walls embedded in the thickness thereof near the top edges thereof, means for attaching a carrying strap to said metallic bearing ring, and means for attaching a flash power unit within the container to said metallic bearing ring so that the weight of said power unit is transferred to the carrying strap mainly through said metallic bearing ring rather than through said foamed plastic material.
Claim 2
Dependent Claim 95 words
A container for a portable high voltage electronic flash power unit comprising a hollow body having side walls of foamed plastic material, a metallic bearing ring extending along said side walls embedded in the thickness thereof near the top edges thereof, means for attaching a carrying strap to said metallic bearing ring, and means for attaching a flash power unit within the container to said metallic bearing ring so that the weight of said power unit is transferred to the carrying strap mainly through said metallic bearing ring rather than through said foamed plastic material.
Claim 3
Dependent Claim 90 words
A container as defined in claim 1, wherein said means for attaching a strap and a power unit to said bearing ring includes a plurality of metal bushes firmly secured to said bearing ring, each of said bushes having a length corresponding substantially to the thickness of the wall where the bush is located and having a bore extending through the bush in the direction of the thickness of the wall, through which bore a fastening element may extend, for attachment to the carrying strap or the power unit, respectively.
Claim 4
Dependent Claim 42 words

Claim 5
Dependent Claim 18 words
A container as defined in claim 2, wherein said bushes are riveted into openings in said bearing ring.
Claim 6
Dependent Claim 26 words
A container as defined in claim 1, wherein said container includes a bottom wall integral with said side walls and also formed of foamed plastic material.
Claim 7
Dependent Claim 23 words
A container as defined in claim 5, further comprising fireproof insulation plates lining the inner faces of said side walls and bottom wall.
Claim 8
Dependent Claim 31 words
A container as defined in claim 1, wherein said foamed plastic material is colored black and has a waterproof leather grain type coating on the exterior surfaces of the container walls.
Claim 9
Dependent Claim 40 words
A container as defined in claim 1, wherein said carrying strap is attached to the container at the inner faces of the walls of the container so that the strap may be folded into the container when not in use.
