Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A photographic camera, comprising: a camera housing having an aperture in the front face thereof; a retractable lens tube positioned in said aperture of said camera housing; a platelike control handle mounted on said camera housing so as to be slidable in a plane parallel to the front of said camera housing and pivotable about an axis of rotation located at a first edge of the front of said camera housing, a storage position wherein said platelike control handle is parallel to the front of said camera housing substantially covering said retractable lens tube, and an operating position wherein said platelike control handle is pivoted at an angle with respect to the front of said camera housing forming a rocking lever; and coupling means mechanically connected between said platelike control handle and said retractable lens tube, for projecting said retractable lens tube beyond the front of said camera housing when said platelike control handle is in said operating position.
Claim 2
Dependent Claim
159 words
A photographic camera, comprising: a camera housing having an aperture in the front face thereof; a retractable lens tube positioned in said aperture of said camera housing; a platelike control handle mounted on said camera housing so as to be slidable in a plane parallel to the front of said camera housing and pivotable about an axis of rotation located at a first edge of the front of said camera housing, a storage position wherein said platelike control handle is parallel to the front of said camera housing substantially covering said retractable lens tube, and an operating position wherein said platelike control handle is pivoted at an angle with respect to the front of said camera housing forming a rocking lever; and coupling means mechanically connected between said platelike control handle and said retractable lens tube, for projecting said retractable lens tube beyond the front of said camera housing when said platelike control handle is in said operating position.
Claim 3
Dependent Claim
54 words
A camera as set forth in claim 1, wherein said platelike control handle comprises a masking slider which is shifted in a plane parallel to the front of said camera housing and a rocker plate connected to said masking slider and pivotably connected to said first edge of the front of said camera housing.
Claim 4
Dependent Claim
32 words
A camera as set forth in claim 2, further comprising a slide guide member mounted on the front of said camera housing, said masking slide being slidable on said slide guide member.
Claim 5
Dependent Claim
20 words
A camera as set forth in claim 3, wherein said masking slider is also slidably mounted on said rocking plate.
Claim 6
Dependent Claim
47 words
A camera as set forth in claim 4, wherein said masking slider has a protruding portion which extends beyond said first edge of said camera housing when said platelike control handle is in said operating position, whereby said platelike control handle is operated as a rocking lever.
Claim 7
Dependent Claim
101 words
A camera as set forth in claims 1, 2 or 5, wherein said coupling means comprises: a coupling lever having a free leg, a coupling leg and a hook region pivotally connected to said control handle; a spring positioned between said control handle and said coupling leg; a feeler lever engaging said free leg and mounted on said rocker plate; and a coupling key engaging said feeler lever such that when said coupling key is depressed said feeler lever pushes on said free leg causing said coupling lever to pivot thereby moving said coupling leg against the bias of said spring.
Claim 8
Dependent Claim
26 words
A camera as set forth in claim 6, wherein said hook region of said coupling lever comprises a hook shaped capture region and an input region.
Claim 9
Dependent Claim
108 words
A camera as set forth in claim 7, wherein said coupling means further comprises: lens tube retracting means, engaging said retractable lens tube, for projecting and retracting said retractable lens tube; a drive lever, having a tenon, positioned between said hook region and said lens tube retracting means, said tenon normally resting in said input of said hook region, and upon said coupler key being depressed moving said coupling lever such that said tenon rides in said capture region of said hook region, whereby said lens tube is retracted when said control handle is rocked towards the front of said camera housing as said coupling key is depressed.
Claim 10
Dependent Claim
80 words
A camera as set forth in claim 5, further comprising: a bent rack mounted on said control handle; a driving gear, having a cam portion, in mesh with said bent rack; film transport means, driven by said driving gear, for advancing camera film having a plurality of sprocket holes, into a position to be exposed; and a cocking lever, engaging said cam portion, for cocking the shutter of said camera, whereby said film is advanced by rocking said control handle.
Claim 11
Dependent Claim
121 words
A camera as set forth in claim 9, wherein said film transport means comprises: a spring mounted on said camera housing; a pivotable control lever, having a feeler finger and a control leg, and having a free leg biased by said spring; a pinion, rotatably mounted on said control leg and in mesh with said drive gear; and winding means, mounted to be rotatable with said pinion, for advancing said camera film, wherein said feeler finger engages said camera film, such that when said feeler finger is forced into one of said plurality of sprocket holes said pivotable control lever is pivoted thereby pivoting said pinion out of mesh with said drive gear and stopping the advance of said camera film.
Claim 12
Dependent Claim
16 words
A camera as set forth in claim 10, wherein said bent rack has a scanning slot.
Claim 13
Dependent Claim
44 words
A camera as set forth in claim 11, further comprising detent means positioned to engage said scanning slot when said feeler finger falls in said sprocket hole, whereby said control handle is locked in a position parallel to the front of said camera housing.
