摘要:
A vehicle comprising: - a resting board (2) for the feet of a user; - a first wheel support (9) and a second wheel support (9) for a pair of front and/or rear wheels; wherein said first wheel support (9) is mounted on said board so that it can turn about a first steering axis (8') and defines a first axis of rotation of the wheel (9'), and wherein said second wheel support (9) is mounted on said board so that it can turn about a second steering axis (8') and defines a second axis of rotation of the wheel (9'); - elastic means operatively connected to said first and second supports for bringing said first and second supports into a reciprocal arrangement, which is designed to determine, in operation, a motion of advance of the vehicle that is substantially rectilinear. The vehicle is characterized in that it comprises a torsion spring (13) arranged with its axis coinciding with one of said first and second steering axes.

The present invention refers to a steering device for sports articles (1) adapted to slide on a supporting surface (2) by means of a plurality of supporting and sliding elements (3) provided in an in-line arrangement; the steering device comprises a chassis (5), to which there is associated at least a carriage 6a adapted to swing relative to said chassis (5), against the force of elastic means (17, 18), about an axis (7) that is inclined by an angle (x with respect to said supporting surface (2) and lies substantially on the median longitudinal plane (4) of the chassis (5). The carriage (6)a is adapted to support at least two supporting and sliding elements (3) in a manner that the respective support axes (25, 26) come to lie substantially parallel to said supporting surface (2) on opposite sides with respect to the pivoting, i.e. swinging centre (27) of said carriage 6a relative to said chassis (5).

A wheeled apparatus for board sports is provided. The wheeled apparatus includes a board, a plurality of wheels supported by a plurality of steering knuckles, and at least one linkage between the board and the steering knuckles. The at least one linkage enables a camber and/or a caster and/or a toe angle of the wheels to be adjusted by pivoting the board.

A track structure capable of returning wheels to a neutral position by using elastic blocks in a steering operation for automatically returning the wheels to a neutral position by body weight shifting is provided. The track structure is provided with a bearing containing chamber having a pivotable attachment section composed of a recess which is formed in one of a support base or a rockable section and is open to the other; an operation section formed on the other of the support base or the rockable section and rotatably fitted in the bearing containing chamber; a pivot shaft section for rotatably supporting the operation section within the bearing containing chamber; and elastic blocks arranged in plural within the bearing containing chamber at equal intervals about the axis of the pivot shaft section, the elastic blocks holding the operation section at the neutral position and, when the operation section pivots to right and left, biasing the operation section in a direction in which the operation section returns to the neutral position.

A skateboard truck assembly with an integrated combination of a system of gears that resemble planetary gears that allow both wheels and a caster to remain on the ground while the skateboard is traveling in a lengthwise manner. At the same time, when the rider leans to one side or the other of the skateboard, the gear assembly causes the "downhill" wheel to rise in the air and the caster to be displaced such that the skateboarder can laterally "slide" or "drift" the skateboard as though it was a snowboard. Because the downhill wheel is raised well above the ground, there is less of a tendency for the downhill wheel to catch on any street irregularities or rocks and stop sliding at inopportune times.

A roller skate having enhanced steerability and stability is disclosed The skate includes a platform for supporting a skater's foot and front and rear wheel trucks secured to the underside of the platform. A pair of front wheels is rotatably mounted in transverse axial alignment on the front wheel truck and a pair of rear wheels is rotatably mounted in transverse axial alignment on said rear wheel truck. The pairs of front and rear wheels are also in parallel axial alignment with each other and mounted on their respective wheel trucks for resiliently controlled, tilting movement about downwardly inclined longitudinal axis. In addition, a fifth wheel is rotatably mounted on the front wheel truck between the pairs of front and rear wheels and in parallel axial alignment with the wheel pairs. An additional preferred roller skate includes a single wheel rotatably mounted to the front toe plate.
