Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
257 words
A camera mounting device including a base member and a head member attached to said base member, said head member including a planar camera mounting surface, a retractable spindle having a threaded external surface meshing with a complimentary threaded opening in said mounting surface, said spindle being movable between a retracted position wherein substantially all of said spindle is located below the plane of said mounting surface and internally of said head and a fully extended position projecting substantially perpendicular to the plane of said mounting surface wherein a substantial proportion of said spindle projects out of the plane of said mounting surface while a proportion is maintained in engagement with the threaded opening of said surface, said spindle during movement between said positions being capable of engaging and meshing with complimentary threads of camera to be mounted on said surface, first gear means mounted on the underside of said mounting surface internally of said head for rotation about an axis substantially parallel to that of said spindle, ring gear means meshing with said first gear means and mounted for rotation relative to said mounting surface about the axis of said spindle, third gear means fixedly mounted to said spindle and meshing with said first gear means in translational manner, whereby upon rotation of said ring gear means the motion imparted thereby to said first gear means causes the third gear means to rotate and to translate along the surface of said first gear means, thereby to move said spindle between said retracted and fully extended positions.
Claim 2
Dependent Claim
257 words
A camera mounting device including a base member and a head member attached to said base member, said head member including a planar camera mounting surface, a retractable spindle having a threaded external surface meshing with a complimentary threaded opening in said mounting surface, said spindle being movable between a retracted position wherein substantially all of said spindle is located below the plane of said mounting surface and internally of said head and a fully extended position projecting substantially perpendicular to the plane of said mounting surface wherein a substantial proportion of said spindle projects out of the plane of said mounting surface while a proportion is maintained in engagement with the threaded opening of said surface, said spindle during movement between said positions being capable of engaging and meshing with complimentary threads of camera to be mounted on said surface, first gear means mounted on the underside of said mounting surface internally of said head for rotation about an axis substantially parallel to that of said spindle, ring gear means meshing with said first gear means and mounted for rotation relative to said mounting surface about the axis of said spindle, third gear means fixedly mounted to said spindle and meshing with said first gear means in translational manner, whereby upon rotation of said ring gear means the motion imparted thereby to said first gear means causes the third gear means to rotate and to translate along the surface of said first gear means, thereby to move said spindle between said retracted and fully extended positions.
Claim 3
Dependent Claim
25 words
The device of claim 1 wherein said camera mounting surface is circular and the axis of said spindle passes through the centre of said circle.
Claim 4
Dependent Claim
16 words
The device of claim 2 wherein said spindle is movable perpendicularly of said camera mounting surface.
Claim 5
Dependent Claim
36 words
The device of claim 2 wherein said ring gear is fixedly mounted on the internal wall of a hollow cylindrical ring element, said ring element having a vertical axis coinciding with the axis of said spindle.
Claim 6
Dependent Claim
180 words
The device of claim 1 wherein said head member is pivotally mounted relative to said base member for pivotal movement about a substantially horizontal axis, and said head member includes a disc having arm projecting downwardly therefrom and terminating in opposite ends of a horizontal pivot pin pivotally connecting said head member to said base member, an abutment secured to the upper surface of said disc and having a flange extending upwardly and attached to the underside of said mounting surface, said mounting surface being circular, and a hollow cylindrical ring element extending between said disc and the underside of said mounting surface and being rotatable about the axis thereof relative thereto, the axis of said ring element passing through the centre of the circle of the mounting surface, said ring element enclosing said abutment and said flange and the inner wall of said ring element being spaced from said abutment, said ring gear means being fixedly mounted on the inner wall of said ring element and the axis of said spindle passes through said circle of the mounting surface.
Claim 7
Dependent Claim
34 words
The device of claim 1 including means for pivoting said head member relative to said base member about a substantially horizontal axis and means for rotating said base member about a substantially vertical axis.
Claim 8
Dependent Claim
126 words
The device of claim 6 wherein said head member is mounted on a horizontal pivot pin for pivotal movement relative to said base member about said axis, and said means for pivoting said head member relative to said base member includes a first bevel gear fixedly mounted on the pivot pin, a second bevel gear meshing with said first bevel gear and fixedly mounted on an axle mounted perpendicularly to said pivot pin and means for rotating said axle about its axis, and said means for rotating said base member about a vertical axis includes a stationary element and a rotatable element, spindle means fixedly mounted on said rotatable element and journalled for rotation relative to said stationary element, and means to rotate said spindle means.
Claim 9
Dependent Claim
136 words
The device of claim 7 wherein said base member is cylindrical and includes hollowed-out sections in which are located said axle and said spindle means, said means for rotating said axle includes fourth gear means fixedly mounted on said wall, fifth gear means meshing with said fourth gear means and fixedly mounted on a first spindle projecting through the external wall of said base member into one of said hollowed-out portions and first knob means on the latter spindle, and said means for rotating said spindle means includes sixth gear means fixedly mounted on said spindle means, seventh gear means meshing with said sixth gear means and fixedly mounted on a second spindle projecting through the external wall of said base member into another of said hollowed-out portions and second knob means on the latter spindle.
