Abstract

Abstract A cover plate is provided which is especially suited to an instant picture type camera employing mirror image deflection for picture taking. However, this cover plate is suited to any still camera having a substantially planar contiguously grouped optical element arrangement. The cover plate is longitudinally slidably mounted in the camera housing relative to the normal viewing position of the camera, and is reciprocally movable between a first position overlying the optical elements mounted in the camera housing and a second position vertically distal thereto.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 178 words
A slidable protective cover for the optometric elements of a camera of the type having the optometric elements thereof contiguously transversely aligned on the front panel of the camera housing thereof comprising, a substantially planar panel overfitting said front panel of said camera, first means mounted on said planar panel, said front panel of said camera housing including a second means corresponding to said first means and complementary thereto, said first and second complementary means being cooperatively connectable for sliding said panel thereon between first and second positions, said first position of said planar panel corresponding to a position of said planar panel overlying said optometric elements, said second position of said planar panel corresponding to a position of said planar panel longitudinally distal to said optometric elements, said camera housing having an interior slot in which said planar panel is reasonably housed in said second position thereof, and cooperating corresponding complementary means on said planar panel and in said camera housing for releasably securing said planar panel in said first and second positions, respectively, on said housing.
Claim 2
Dependent Claim 178 words
A slidable protective cover for the optometric elements of a camera of the type having the optometric elements thereof contiguously transversely aligned on the front panel of the camera housing thereof comprising, a substantially planar panel overfitting said front panel of said camera, first means mounted on said planar panel, said front panel of said camera housing including a second means corresponding to said first means and complementary thereto, said first and second complementary means being cooperatively connectable for sliding said panel thereon between first and second positions, said first position of said planar panel corresponding to a position of said planar panel overlying said optometric elements, said second position of said planar panel corresponding to a position of said planar panel longitudinally distal to said optometric elements, said camera housing having an interior slot in which said planar panel is reasonably housed in said second position thereof, and cooperating corresponding complementary means on said planar panel and in said camera housing for releasably securing said planar panel in said first and second positions, respectively, on said housing.
Claim 3
Dependent Claim 69 words
The slidable cover as claimed in claim 1, said first means mounted on said planar panel comprising at least one rib formed on the surface thereof, said corresponding complementary second means comprising at least one longitudinally formed recess in said housing, said at least one recess extending upwardly on said camera housing past said optometric elements mounted therein, said at least one rib being slidably engageable in said recess.
Claim 4
Dependent Claim 53 words
The slidable cover as claimed in claim 2, said at least one rib comprising a pair of said ribs formed on said surface of said panel in closely spaced parallel relationship, and said at least one recess formed in said housing comprising a pair of said recesses corresponding to said pair of ribs.
Claim 5
Dependent Claim 108 words
The slidable cover as claimed in claim 1, said cooperating corresponding means on said panel and in said camera housing for releasably securing said planar panel in said first and second positions, respectively, on said housing comprising a first and second vertically aligned laterally elongated depression formed in said housing respectively successively spaced from said optometric elements therein, said first and second depressions corresponding respectively to said first and second positions of said panel on said camera housing, and said planar panel including a resiliently elastic tongue depending therefrom, said tongue carrying a rib therein registrable in said first and second depressions for releasably securing said panel therein.
Claim 6
Dependent Claim 29 words
The slidable cover as claimed in claim 1, said housing including a channel member, said planar panel being slidably receivable in said channel member in said second position thereof.
Claim 7
Dependent Claim 95 words
The slidable cover as claimed in claim 1, said second means comprising a first and second operatively connected gear wheel, said first and second gear wheels being rotatably mounted on said camera housing, said first means comprising means for translating rotative motion of said first and second gear wheels to linear movement, said first means sliding said panel linearly on said housing as said first and second gear wheels are rotated, and means for rotating said first and second gear wheels in at least one respective direction, said rotating means being mounted on said housing.
Claim 8
Dependent Claim 42 words
The slidable cover as claimed in claim 6, said means for translating rotative motion of said gear wheels to linear movement comprising first and second racks mounted on said panel, each of said racks being operatively connected to a corresponding gear wheel.
Claim 9
Dependent Claim 79 words
The slidable cover as claimed in claim 7, said means for rotating said gear wheels comprising a sector gear pivotally mounted on said housing, said sector gear being operatively connected to at least one of said gears when said panel is in said second position thereof on said housing, and means for biasing said sector gear from a first to a second position, said sector gear rotating said gears as it moves from its first to its second positions.
Claim 10
Dependent Claim 33 words
The slidable cover as claimed in claim 8 including a brake means releasably connectable to said sector gear in said first position thereof for releasably securing said sector gear in said first positon.
Claim 11
Dependent Claim 36 words
The slidable cover as claimed in claim 9, said brake means comprising a pivotally mounted pawl having a leaf engageable with said sector gear, and means for biasing said pawl into engagement with said sector gear.
