Abstract
Abstract A non-folding adapter for use with a photographic camera having an optical axis in a nonparallel orientation with respect to a supporting base of the camera. The adapter permits a realignment of the camera''s optical axis to a horizontal position such that it may be conveniently coupled with a conventional tripod or positioned on a flat surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
A non-folding adapter for a photographic camera having an objective lens and a plurality of housing elements, the optical axis of said lens being oriented at an acute angle with respect to a supporting base element of said housing elements, said adapter comprising: a first planar section engageable with said supporting base element for receiving and supporting said camera; a second section angularly disposed with respect to said first section, the planes of said first section and said second section being oriented at an angle substantially equal to said acute angle between said optical axis and said base element; flexible detent means for releasably attaching said adapter to said camera, said flexible detent means being frictionally engageable with a portion of said base elEment, and said detent means including forward limiting means, formed as a portion thereof for preventing said photographic camera from moving longitudinally forwardly on said adapter when said adapter is attached to said camera, said limiting means being configured to abuttably engage one of said housing elements; and means extending from said first planar section for limiting rearward longitudinal movement of said camera on said adapter when said adapter is attached to said camera.
Claim 2
Dependent Claim
197 words
A non-folding adapter for a photographic camera having an objective lens and a plurality of housing elements, the optical axis of said lens being oriented at an acute angle with respect to a supporting base element of said housing elements, said adapter comprising: a first planar section engageable with said supporting base element for receiving and supporting said camera; a second section angularly disposed with respect to said first section, the planes of said first section and said second section being oriented at an angle substantially equal to said acute angle between said optical axis and said base element; flexible detent means for releasably attaching said adapter to said camera, said flexible detent means being frictionally engageable with a portion of said base elEment, and said detent means including forward limiting means, formed as a portion thereof for preventing said photographic camera from moving longitudinally forwardly on said adapter when said adapter is attached to said camera, said limiting means being configured to abuttably engage one of said housing elements; and means extending from said first planar section for limiting rearward longitudinal movement of said camera on said adapter when said adapter is attached to said camera.
Claim 3
Dependent Claim
16 words
The adapter according to claim 1 in which said detent means extend from said first section.
Claim 4
Dependent Claim
48 words
The adapter according to claim 1 in which said second section is formed having a bore therein through which said adapter may be coupled to a tripod, said bore being located substantially below the center of gravity of said camera when said camera is mounted to said adapter.
Claim 5
Dependent Claim
52 words
The adapter according to claim 1 in which said means for limiting the rearward longitudinal movement of said camera is formed as a vertical wall member at a rearward edge of said first section, said vertical wall member being engageable with at least a portion of said base element of said camera.
Claim 6
Dependent Claim
38 words
The adapter according to claim 1 in which a portion of the area between the plane of said first section and the plane of said second section is hollowed out for permitting the storage of photographic camera accessories.
Claim 7
Dependent Claim
24 words
The adapter according to claim 1 in which the area between the planes of said first section and of said second section is solid.
Claim 8
Dependent Claim
23 words
The adapter according to claim 1 in which said first section has an inside width substantially equal to the width of said camera.
Claim 9
Dependent Claim
23 words
The adapter according to claim 7 in which said second section has a width substantially less than the width of said first section.
Claim 10
Dependent Claim
84 words
The adapter according to claim 1 in which foot means are provided on the bottom of said first planar section, said foot means and a linear bottom portion of said second section establishing a plane for providing a supporting base for said adapter, said plane established by said foot means and said linear bottom portion of said second section and said plane of said first section being oriented at an angle substantially equal to said acute angle between said optical axis and said base.
Claim 11
Dependent Claim
31 words
The non-folding adapter according to claim 1 in which said forward limiting means abuttably engages a housing element adjacent to said base element when said adapter is attached to said camera.
Claim 12
Dependent Claim
49 words
The non-folding adapter according to claim 10 in which said forward limiting means is formed as a selectively sloped portion of said flexible detent means, said sloped portion of the flexible detent means being configured to fit between said housing element adjacent said base element and said base element.
