Underwater one-time-use camera with combination film winding clutch and shutter release

Claim 2

A camera comprising a film winding knob manually rotatable to rotate a spool to wind a filmstrip onto the spool, clutching means located between said film winding knob and the spool for allowing the film winding knob to be manually rotated without rotating the spool, and a shutter release button manually depressible to initiate picture-taking, is characterized in that: said clutching means includes a clutch component supported to be depressed to initiate picture-taking responsive to manual depression of said shutter release button.

Claim 3

A camera as recited in claim 1, wherein resilient means urges said clutch component against said shutter release button to make manual depression of the shutter release button depress the clutch component.

Claim 4

A camera as recited in claim 2, wherein a latch restrains a high energy actuator from striking a shutter blade to initiate picture-taking, and said clutch component is supported to move said latch to release said high energy actuator responsive to manual depression of said shutter release button.

Claim 5

A camera as recited in claim 1, wherein a film winding thumbwheel is manually rotatable in engagement with the spool to rotate the spool and film metering means can engage the thumbwheel to prevent rotation of the thumbwheel, an outer watertight housing encases said camera, said film winding knob and said shutter release button are located on said watertight housing in coaxial relation with said film winding thumbwheel, and said clutch component engages said film winding knob and said film winding thumbwheel to make manual rotation of the knob rotate the clutch component to in turn rotate the thumbwheel but which can disengage the knob and/or the thumbwheel when said film metering means engages the thumbwheel to permit the knob to be manually rotated without rotating the thumbwheel.

Claim 6

A camera as recited in claim 4, wherein said clutching means includes a circular array of teeth projecting from said film winding knob into a central opening in the knob and a mating array of teeth projecting from said clutch component into engagement with said circular array of teeth in said central opening to make manual rotation of the knob rotate the clutch component, and at least one of said arrays of teeth being constructed to displace the other when said film metering means engages said film winding thumbwheel to permit said film winding knob to be manually rotated without rotating the thumbwheel.

Claim 7

A camera as recited in claim 5, wherein said teeth projecting from said clutch component are supported on respective flexible beams of the clutch component to allow said teeth projecting from said film winding knob to displace the teeth projecting from the clutch component when said film metering means engages said film winding thumbwheel.

Claim 8

A camera as recited in claim 1, wherein said shutter release button, said film winding knob and said clutch component are arranged in coaxial relation.

Claim 9

A watertight housing for encasing a camera comprises a film winding knob manually rotatable to rotate a spool to wind a filmstrip onto the spool in the camera, clutching means located between said film winding knob and the spool for allowing the film winding knob to be manually rotated without rotating the spool, and a shutter release button manually depressible to initiate picture-taking with the camera, is characterized in that: said clutching means includes a clutch component supported to be depressed to initiate picture-taking with the camera responsive to manual depression of said shutter release button.

Claim 10

A watertight housing for encasing a camera comprises a film winding knob manually rotatable to rotate a spool to wind a filmstrip onto the spool in the camera, clutching means located between said film winding knob and the spool for allowing the film winding knob to be manually rotated without rotating the spool, and a shutter release button manually depressible to initiate picture-taking with the camera, is characterized in that: said clutching means includes a clutch component supported to be depressed to initiate picture-taking with the camera responsive to manual depression of said shutter release button.

Claim 11

A watertight housing as recited in claim 8, wherein said shutter release button, said film winding knob and said clutch component are arranged in coaxial relation.
