Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A binocular construction comprising a pair of barrels within each of which are lenses and a prism defining a light path; means mounting said barrels side by side for relative rotation about an axis therebetween; a filter support for each of said barrels; means mounting one of said filter supports wholly within one of said barrels and the other filter support wholly within the other of said barrels for rotation about parallel axes of rotation offset from the associated light path; at least one filter carried by each of said filter supports for rotation therewith and extending radially outwardly from its axis a distance sufficient to intercept light traversing the associated light path; driving means; means mounting said driving means between said barrels for rotation about the axis of rotation of said barrels; and drive transmitting means extending from said driving means into said barrels and coupling said driving means to each of said filter supports for rotating said filter supports conjointly about their axes.
Claim 2
Dependent Claim
165 words
A binocular construction comprising a pair of barrels within each of which are lenses and a prism defining a light path; means mounting said barrels side by side for relative rotation about an axis therebetween; a filter support for each of said barrels; means mounting one of said filter supports wholly within one of said barrels and the other filter support wholly within the other of said barrels for rotation about parallel axes of rotation offset from the associated light path; at least one filter carried by each of said filter supports for rotation therewith and extending radially outwardly from its axis a distance sufficient to intercept light traversing the associated light path; driving means; means mounting said driving means between said barrels for rotation about the axis of rotation of said barrels; and drive transmitting means extending from said driving means into said barrels and coupling said driving means to each of said filter supports for rotating said filter supports conjointly about their axes.
Claim 3
Dependent Claim
37 words
A construction according to claim 1 wherein said driving means comprises a driving gear, a driven gear carried by each og said filter supports, and a rotary shaft extending from each driven gear to said driving gear.
Claim 4
Dependent Claim
12 words
A construction according to claim 2 wherein said rotary shaft is flexible.
Claim 5
Dependent Claim
20 words
A construction according to claim 1 wherein each of said filter supports has a section thereof which is optically clear.
Claim 6
Dependent Claim
20 words
A construction according to claim 1 wherein each of said filter supports has a plurality of circumferentially spaced, different filters.
Claim 7
Dependent Claim
17 words
A construction according to claim 5 wherein one of the filters of each filter support is polarized.
Claim 8
Dependent Claim
20 words
A construction according to claim 6 wherein each of said polarized filters has a circumferential length of at least 90°.
Claim 9
Dependent Claim
24 words
A construction according to claim 1 including detent means acting on said filter supports for releasably maintaining them in a selected position of adjustment.
Claim 10
Dependent Claim
18 words
A construction according to claim 1 including indicia for identifying said filter; and means for viewing said indicia.
Claim 11
Dependent Claim
13 words
A construction according to claim 9 wherein said viewing means is a magnifier.
Claim 12
Dependent Claim
11 words
A construction according to claim 9 wherein said indicia is luminescent.
