Abstract
Abstract A folding camera including first and second housings pivotally mounted for movement between operative and inoperative positions and being interconnected by a flexible bellows. When the housings are in the operative position, areas of the bellows which would ordinarily be exposed to ambient light and to engagement by the fingers of a user are shielded therefrom by three planar, substantially rigid, opaque members which occupy a minimum of space when the housings are in the inoperative position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
308 words
A folding camera comprising: a first housing having a leading end wall, a trailing end wall, and a pair of laterally spaced side walls interconnecting the lateral ends of said leading end and trailing end walls so as to define a chamber therebetween; a second housing having a leading end, a trailing end, and first and second laterally spaced side walls; a module including a lens and shutter assembly fixedly supported at said leading end of said second housing; a flexible bellows interconnecting said first and second housings; means for pivotally coupling said trailing end of said second housing to said first housing at a point adjacent said trailing end wall for pivotal movement between a folded inoperative position wherein substantial portions of said first and second side walls of said second housing and said module are located within said chamber, and an erected operative position wherein said module is spaced from said leading end wall of said first housing, and said side walls of said first and second housings define triangular shaped openings on each side of said camera adjacent sides of said bellows; first and second laterally spaced skirts fixedly secured to said second housing so as to close off said triangular shaped openings when said second housing is in said erected position; and a plate having one end pivotally coupled to said first housing and an opposite second end located in enagement with a lower surface of said module when said second housing is in said erected position, said plate having a width substantially equal to the lateral distance between said first skirt and one of said side walls of said first housing to thereby close off the space between said leading end wall and said module, whereby said bellows is shielded from the ambient light and from contact by the user of said camera.

A folding camera comprising: a first housing having a leading end wall, a trailing end wall, and a pair of laterally spaced side walls interconnecting the lateral ends of said leading end and trailing end walls so as to define a chamber therebetween; a second housing having a leading end, a trailing end, and first and second laterally spaced side walls; a module including a lens and shutter assembly fixedly supported at said leading end of said second housing; a flexible bellows interconnecting said first and second housings; means for pivotally coupling said trailing end of said second housing to said first housing at a point adjacent said trailing end wall for pivotal movement between a folded inoperative position wherein substantial portions of said first and second side walls of said second housing and said module are located within said chamber, and an erected operative position wherein said module is spaced from said leading end wall of said first housing, and said side walls of said first and second housings define triangular shaped openings on each side of said camera adjacent sides of said bellows; first and second laterally spaced skirts fixedly secured to said second housing so as to close off said triangular shaped openings when said second housing is in said erected position; and a plate having one end pivotally coupled to said first housing and an opposite second end located in enagement with a lower surface of said module when said second housing is in said erected position, said plate having a width substantially equal to the lateral distance between said first skirt and one of said side walls of said first housing to thereby close off the space between said leading end wall and said module, whereby said bellows is shielded from the ambient light and from contact by the user of said camera.
Claim 3
Dependent Claim
34 words
A folding camera as defined in claim 1 wherein said first skirt includes a latch engageable with a pin on said first housing for releasably securing said second housing in said folded inoperative position.
Claim 4
Dependent Claim
29 words
A folding camera as defined in claim 1 wherein said plate is located in face-to-face relation to said module when said second housing is in said folded inoperative position.
Claim 5
Dependent Claim
35 words
A folding camera as defined in claim 1 wherein said first and second skirts are dimensioned so as to be located wholly within said chamber when said second housing is in said folded inoperative position.
