Abstract
Abstract A snorkel lens system having a first tubular member and a second tubular member or vertical relay tube, disposed perpendicular with respect to the first tubular member. A first axis of rotation is centrally disposed through the first tubular member and a second axis of rotation is centrally disposed through the second tubular member. The first axis of rotation is perpendicular to the second axis of rotation. The second tubular member or vertical relay tube can be rotated about both of the two perpendicular axes in two perpendicular planes to provide a three dimensional filming special effect.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
A snorkel lens system comprising: a first tubular member having a fixed portion connected to a camera, and a rotatable portion having an opposite end, said first tubular member including a first axis of rotation centrally disposed therethrough; a mirror housing having a first opening connected to said opposite end of said rotatable portion of said first tubular member and a second opening perpendicular to said first opening; a second tubular member having a first end connected to said second opening of said mirror housing and a second opposite end, said second tubular member including a second axis of rotation centrally disposed therethrough, said second axis being perpendicular to said first axis; a prism housing having a first opening connected to said second opposite end of said second tubular member and a second opening disposed perpendicular to said first opening; and a lens housing connected to said second opening of said prism housing and having a front adapter for receiving additional attachment lenses, whereby said second tubular member in conjunction with said mirror housing and said rotatable portion of said first tubular member is rotatable about said first axis and said second tubular member is independently rotatable about said second axis, so that the lens attachments connected to said front adapter can be rotated about said two perpendicular axes in two perpendicular planes to provide a three dimensional filming effect.
Claim 2
Dependent Claim
230 words
A snorkel lens system comprising: a first tubular member having a fixed portion connected to a camera, and a rotatable portion having an opposite end, said first tubular member including a first axis of rotation centrally disposed therethrough; a mirror housing having a first opening connected to said opposite end of said rotatable portion of said first tubular member and a second opening perpendicular to said first opening; a second tubular member having a first end connected to said second opening of said mirror housing and a second opposite end, said second tubular member including a second axis of rotation centrally disposed therethrough, said second axis being perpendicular to said first axis; a prism housing having a first opening connected to said second opposite end of said second tubular member and a second opening disposed perpendicular to said first opening; and a lens housing connected to said second opening of said prism housing and having a front adapter for receiving additional attachment lenses, whereby said second tubular member in conjunction with said mirror housing and said rotatable portion of said first tubular member is rotatable about said first axis and said second tubular member is independently rotatable about said second axis, so that the lens attachments connected to said front adapter can be rotated about said two perpendicular axes in two perpendicular planes to provide a three dimensional filming effect.
Claim 3
Dependent Claim
62 words
The snorkel lens system according to claim 1, wherein said first tubular member further comprises: a camera mount disposed on an end of said first fixed portion for connecting the super snorkel lens to the camera; a lens mounted within said first tubular member; an iris diaphragm disposed within said second rotatable portion; and a focus adjustment disposed within said fixed portion.
Claim 4
Dependent Claim
54 words
The snorkel lens system according to claim 1, further comprising: a gear mechanism connecting the second opening of said mirror housing with the first end of said second tubular member, said gear mechanism for rotating said second tubular member about the second axis, said gear mechanism including a dampener for providing smooth rotational movement.
Claim 5
Dependent Claim
21 words
The snorkel lens system according to claim 3, wherein said second tubular member further comprises a plurality of lenses disposed therein.
Claim 6
Dependent Claim
32 words
The snorkel lens system according to claim 3, wherein said mirror housing includes an angularly disposed mirror for transmitting light images directly from said second tubular member into said first tubular member.
Claim 7
Dependent Claim
21 words
The snorkel lens system according to claim 4, wherein at least one of said plurality of lenses is an achromatic lens.
Claim 8
Dependent Claim
29 words
The snorkel lens system according to claim 1, wherein said prism housing includes a 90° prism for transmitting images received through said lens housing into said second tubular member.
Claim 9
Dependent Claim
20 words
The snorkel lens system according to claim 3, wherein said lens housing is watertight and includes a lens mounted therein.
