Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
An open air duct bicycle saddle adjustable mounting device including; a base mounting support means; vertical support means comprised of two vertical structural elements extending perpendicularly upwards from outside edges of said base mounting support means, said vertical structural elements supporting a bicycle saddle at their upper ends, and being spaced and shaped to form a hollow air duct when viewed from a frontal cross-section view, specifically to receive and direct forward air flow into the turbulent wake of a rider; said vertical structural elements having at their upper ends a mounting surface for said bicycle saddle, fastening means for said bicycle saddle, and adjustment means for vertical, horizontal, and inclination adjustment of said bicycle saddle.
Claim 2
Dependent Claim
116 words
An open air duct bicycle saddle adjustable mounting device including; a base mounting support means; vertical support means comprised of two vertical structural elements extending perpendicularly upwards from outside edges of said base mounting support means, said vertical structural elements supporting a bicycle saddle at their upper ends, and being spaced and shaped to form a hollow air duct when viewed from a frontal cross-section view, specifically to receive and direct forward air flow into the turbulent wake of a rider; said vertical structural elements having at their upper ends a mounting surface for said bicycle saddle, fastening means for said bicycle saddle, and adjustment means for vertical, horizontal, and inclination adjustment of said bicycle saddle.
Claim 3
Dependent Claim
274 words
The open air duct bicycle saddle mounting device of claim 1, wherein said base mounting support means is comprised of a seat post with interior threads, a frame mounting plate with a horizontal groove in its interior for horizontal adjustments, and bolt, wedge, and lock washer assembly, and wherein said frame mounting plate has lugs and fasteners for attachment of said vertical structural elements, and wherein said vertical structural elements consist of side walls of an inverted u-shaped, elongated, telescopic, air duct sleeve with two vertical grooves mounting plate, and wherein said saddle and inverted, u-shaped, elongated, telescopic, air duct sleeve are made of one of the following materials, including: metal, fiber reinforced composites, and injected molded plastic, and any combination thereof; and wherein said adjustment means for vertical adjustment of said structurally integrated bicycle saddle consists in the sliding of said seat post in the seat tube of a bicycle frame and clamping said seat post in its proper position and in sliding said inverted, u-shaped, elongated, telescopic, air duct sleeve along said two vertical grooves relative to said base mounting plate and fastening said inverted, u-shaped, elongated, telescopic, air duct sleeve in its proper position with said fasteners, and wherein horizontal adjustment means consists in moving said base mounting plate along said horizontal groove and then fastening said base mounting plate in its proper position with said bolt, wedge, and lock washer assembly, and wherein said inclination adjustment means consist in making independent adjustments of said inverted, u-shaped, elongated, telescopic, air duct sleeve along one of said vertical grooves and then fastening said inverted, u-shaped, elongated, telescopic sleeve in its proper position.
Claim 4
Dependent Claim
40 words
The open air duct bicycle saddle mounting device of claim 1, wherein said base mounting support means is adapted for use on a custom fiber composite frame, wherein a frame mounting plate is mounted directly to a mating mounting surface.
Claim 5
Dependent Claim
54 words
The open air duct bicycle saddle mounting device of claim 2, wherein the cross-sectional shape of said seat post of said base mounting support means is varied to an aerodynamic cross-section including an elliptical and a tear drop cross-section and as necessary to fit the seat tube of any bicycle requiring a seat post.
Claim 6
Dependent Claim
171 words
The open air duct bicycle saddle mounting device of claim 2, wherein said base mounting support means consists of a seat post to which said hollow air duct is affixed, said vertical structural elements having at each of their upper ends a mounting surface and bracket and bolt fastening means for fastening said bicycle saddle to said mounting surface and wherein said adjustment means for vertical adjustment consists in sliding said seat post in a seat tube of a bicycle frame and clamping said seat post in its proper position, and wherein said adjustment means for horizontal adjustment consists in sliding mounting rails of said bicycle saddle in brackets and clamping them in their proper position, and wherein adjustment means for said inclination adjustment comprises an elongated slot formed in each of the mounting surfaces, lower bolt of said bracket and bolt fastening means may be adjustably clamped along said slot to its proper position, and wherein internal stiffening fins may be added to said hollow air duct and added thereto.
Claim 7
Dependent Claim
36 words
The open air duct bicycle saddle mounting device of claim 5, wherein said saddle is of a shape to enhance air flow and may be made of one of: fiber reinforced composites, and injected molded plastic.
Claim 8
Dependent Claim
34 words
