Abstract

Abstract A lens mount configured to permit relative movement between the camera axis and lens axis while maintaining the image plane and focal plane in substantially parallel relation relative to each other wherein the lens mount comprises an inner and outer movable circular disc disposed in fixed spaced relationship relative to each other by a movable circular disc spacer, an inner stop plate including a circular stop aperture disposed in surrounding relationship relative to the movable circular disc spaces, a tiltable lens mounting ring to operatively receive a lens thereon attached to the outer movable disc, a rear base plate attachable to a camera and a forward housing plate disposed on opposite sides of the inner stop plate, and an inner and outer disc stop plate each including a circular stop aperture disposed in surrounding relationship relative to the inner and outer movable circular discs respectively, the inner and outer movable circular discs, movable circular disc spacer and tiltable lens mounting ring each including a central aperture formed therein in axial alignment relative to each other which together form a lateral adjustment unit movable within the housing comprising the rear base plate and forward housing plate such that the movement of the lateral adjustment unit is limited by the engagement of the lateral adjustment unit with the stop apertures.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 212 words
A lens mount configured to permit relative movement between the camera axis and lens axis while maintaining the image plane and focal plane in substantially parallel relation relative to each other: said lens mount comprising a housing to operatively retain an adjustment means in limited movable relation relative to a stop means, said adjustment means comprising an inner and outer movable disc held in a fixed spaced relation relative to each other by a movable disc spacer disposed therebetween, a movable lens mounting ring to operatively receive a lens thereon coupled to said outer movable disc, said inner and outer movable disc, said movable disc spacer and said movable lens mounting ring each including a centrally disposed aperture formed therein, each said central disposed aperture coaxially aligned relative to said other centrally disposed aperture, said stop means comprising an inner stop plate including a centrally disposed stop aperture formed therein affixed to said housing, said movable disc spacer being movably disposed within said stop aperture such that the outer periphery of said movable disc spacer is engagable with the periphery of said stop aperture as said adjustment means is moved relative to said housing and said inner stop plate to limit the lateral movement of said adjustment means relative to said housing.
Claim 2
Dependent Claim 212 words
A lens mount configured to permit relative movement between the camera axis and lens axis while maintaining the image plane and focal plane in substantially parallel relation relative to each other: said lens mount comprising a housing to operatively retain an adjustment means in limited movable relation relative to a stop means, said adjustment means comprising an inner and outer movable disc held in a fixed spaced relation relative to each other by a movable disc spacer disposed therebetween, a movable lens mounting ring to operatively receive a lens thereon coupled to said outer movable disc, said inner and outer movable disc, said movable disc spacer and said movable lens mounting ring each including a centrally disposed aperture formed therein, each said central disposed aperture coaxially aligned relative to said other centrally disposed aperture, said stop means comprising an inner stop plate including a centrally disposed stop aperture formed therein affixed to said housing, said movable disc spacer being movably disposed within said stop aperture such that the outer periphery of said movable disc spacer is engagable with the periphery of said stop aperture as said adjustment means is moved relative to said housing and said inner stop plate to limit the lateral movement of said adjustment means relative to said housing.
Claim 3
Dependent Claim 109 words
The lens mount of claim 1 where in said stop means further include an inner and outer disc stop disc stop plate each including a centrally disposed aperture formed thereon affixed to said housing on opposite sides of said inner stop plate, said inner and outer movable discs being movably disposed with said centrally disposed apertures of said inner and outer disc stop plates respectively such that the outer periphery of said inner and outer movable discs are engagable with the periphy of said centrally disposed apertures of said inner and outer disc stop plates respectively to limit the lateral movement of said adjustment means relative to said housing.
Claim 4
Dependent Claim 54 words
The lens mount of claim 2 wherein said inner and outer movable disc comprise an inner and outer movable circular disc respectively and said movable disc spacer comprises a movable circular disc spacer, and said centrally disposed apertures of said inner stop plate and inner and outer disc stop plates are circular in configuration.
Claim 5
Dependent Claim 27 words
The lens mount of claim 1 wherein said adjustment means further includes a control arm attached thereto to laterally adjust said adjustment means relative to said housing.
Claim 6
Dependent Claim 72 words
The lens mount of claim 4 wherein said control arm comprises an inner leg attached to said movable lens mounting ring and an outer leg including an aperture formed therein to receive post extending outwardly from said outer movable disc, a bias mounted on said post and a fastner movably coupled to said post such that movement of said fastner relative to said post tilts said adjustment means relative to said housing.
Claim 7
Dependent Claim 31 words
The lens mount of claim 5 wherein said outer movable circular disc and said movable circular disc spacer each include a notch to receive the inner portion of said inner leg.
