Abstract
Abstract A camera has a housing and a T-shaped handgrip turnably mounted on a side wall of the housing. A shutter release element is mounted in the housing. A trigger button is mounted in the handgrip. A coupling is interposed between the button and the shutter release element and is composed of two slidable pins extending normal to each other and having cooperating cam faces so arranged that when one pin moves towards the other in response to depressing of the trigger button, it causes the other pin to slide toward and actuate the shutter release element.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
197 words
A photographic camera, particularly a still camera, comprising a housing provided with a lens having an optical axis; a shutter release element in said housing; a handgrip mounted on said housing turnable about a pivot axis transverse to said optical axis and including one part extending along said pivot axis and another part extending in a direction transverse to said pivot axis; a trigger button mounted in said other part for sliding movement in said direction; and means for coupling said trigger button with said shutter release element to actuate the latter in response to said sliding movement of the former, comprising a first pin slidable in said one part lengthwise of said pivot axis from a rest position to an operating position in which it operates said shutter release element, a second pin slidable in said other part together with said button in said direction from a starting position towards and away from said first pin, and cooperating portions on said pins engageable with one another in response to sliding of said second pin towards said first pin and operative for imparting to said first pin upon such engagement a sliding movement to said operating position.
Claim 2
Dependent Claim
197 words
A photographic camera, particularly a still camera, comprising a housing provided with a lens having an optical axis; a shutter release element in said housing; a handgrip mounted on said housing turnable about a pivot axis transverse to said optical axis and including one part extending along said pivot axis and another part extending in a direction transverse to said pivot axis; a trigger button mounted in said other part for sliding movement in said direction; and means for coupling said trigger button with said shutter release element to actuate the latter in response to said sliding movement of the former, comprising a first pin slidable in said one part lengthwise of said pivot axis from a rest position to an operating position in which it operates said shutter release element, a second pin slidable in said other part together with said button in said direction from a starting position towards and away from said first pin, and cooperating portions on said pins engageable with one another in response to sliding of said second pin towards said first pin and operative for imparting to said first pin upon such engagement a sliding movement to said operating position.
