Abstract
This skateboard invention has novel swiveling caster wheels mounted on a cross carriage (axle) holding spaced apart swivel caster wheels in place on the undersurface of the board by fixed in place fastening brackets. Dual front and dual rear caster wheels—two in front and two in the rear—as well as a three caster wheeled skateboard is disclosed. Inwardly directed axle stubs (angled toward the center of the board, front and back) are employed with said stubs holding long front and long rear caster arms with wheel hubs supported by the long caster arms. A centering movement for the cross axles—whether front and/or rear—and each caster wheel is disclosed such that the cross axle and/or wheel returns itself to an initial straight line position.
Claims15
A skateboard of a tear drop shape with said board having a front end, a rear end, a centerline that runs longitudinally the length of the board with front end and rear end mounting studs on said center line, said skateboard comprising:
- said board having a single deck consisting of a unitary construction of rigid essentially unyielding material;
- at least three caster wheels for said board with all of said wheels selected of the long caster variety wherein the distance between a mounting point for a caster wheel to the caster wheel axis is a distance of about 4 to 6 inches;
- and further wherein said at least three wheels are oriented from the bottom of said single board in the following manner:
- a front caster wheel of said three is fixed on a front end mounting stud underneath the front end of said single unitary board and adapted with a swivel movement about the board's longitudinal line;
- a cross arm axle mounted on said rear end mounting stud;
- a pair of said long caster wheels spaced apart to form an opposed pair of rear caster wheels mounted on a cross arm axle for providing swivel movement of said pair of rear caster wheels about said rigid, unitary board's longitudinal axis;
- and
- spring loaded centering means incorporated within the swivel for each one of said caster wheels and said cross arm axle for maintaining said cross arm axle and said caster wheels in a neutral or in line position except during turns and maneuvers of said skateboard as initiated by a rider shifting his/her weight on said simile unitary board.
A skateboard comprising;
- a single deck consisting of a unitary construction of rigid essentially unyielding material;
- at least three caster wheels for said board with all of said wheels selected of the long caster variety wherein the distance between a mounting point for a caster wheel to the caster wheel axis is a distance of about 4 to 6 inches;
- and further wherein said at least three wheels are oriented from the bottom of said single board in the following manner:
- a front caster wheel of said three is fixed on a front end mounting stud underneath the front end of said single unitary skateboard deck and adapted with a swivel movement about the board's longitudinal line
- a cross arm axle mounted on said rear end mounting stud;
- a pair of said long caster wheels spaced apart to form an opposed pair of rear caster wheels mounted on said cross arm axle for providing swivel movement of said pair of rear caster wheels about said rigid, unitary board's longitudinal axis;
- spring loaded centering means incorporated within the swivel for each one of said caster wheels and for said cross arm axle for maintaining said cross arm axle and said caster wheels in a neutral or in line position except during turns and maneuvers of said skateboard as initiated by a rider shifting his/her weight on said single unitary board;
- a self centering spring connected at an anchor bracket along the longitudinal axis;
- the skateboard further characterized by said other end of said centering spring is connected by a Y-shaped brace rigidly spanning across the rear cross axle with the open part of the Y shape being rigidly fixed to the rear long caster wheel pair;
- a skateboard braking mechanism formed at the rear end of said board, with said braking mechanism being normally biased in an upward non-braking position;
- but
- readily activated downward by the user's heel for braking purposes;
- and
- a frictional plug that is linked to said rear end of said single unitary board for providing a frictional drag as said plug is forced downward by the user into frictional contact against the surface upon which the skateboard is operated when said braking system is activated by the skateboard rider.
