摘要:
A vehicle for the movement of a driver includes a rolling element, a carrier element supported by the rolling element, a drive arrangement supported by the carrier element and configured to drive the rolling element, and a control unit, by way of which the drive arrangement is steered in a desired travel direction depending on the inclination of the carrier element and the inclination direction of the carrier element. The vehicle is configured such that during operation of the vehicle, the driver stands freely and balances on the carrier element. In a particular embodiment, the rolling element rolling is a ball and the vehicle can be moved in any desired travel direction via the drive arrangement, with the driver being in contact with the vehicle exclusively by way of the driver's feet, and as the case may be, further by way of the driver's lower legs.

An apparatus for receiving one or more attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a coupling mechanism and configured to receive one of the one or more attachments. Each attachment providing the exercise accessory to the deck and the coupling mechanism of each of the one or more openings being configured to couple the attachment with the opening after the opening has received the attachment and to attach the exercise accessory with the deck and provide the exercise mode associated with the exercise accessory.

A braking device is provided for an in-line skate where the braking device selectively alters the motion of the in-line skate depending upon the angulation of the in-line skate relative to a surface. As a user angulates or tilts the in-line skate, the braking device increasingly engages the surface to provide a braking force to alter the motion of the in-line skate.

A wheel for an inline skate type roller skate includes a wheel rim portion, a tread surface on the wheel rim portion and at least one ball bearing located entirely within the outer contour of the wheel. Disk-type seals mounted on the inner race of the ball bearing cover the axially outer surfaces of the bearing to protect the bearing against the entry of contaminants. The seals are also located entirely within the outer contour of the wheel.

A urethane wheel including a hard urethane hub formed with a rim facing radially outward, and including stand-off ribs spaced equidistant thereabout. The stand-off ribs having centering notches opening radially outward. A thin wall polyurethane annular bladder with an interior annular stand-off skirt facing radially inward, contacting the centering notches of the stand-off ribs, and cooperating to position the bladder both radially and axially about the rim. The tire body is formed of soft polyurethane which surrounds the rim, encapsulates the bladder creating and integral cavity, and forms a contoured surface. A method of manufacturing the wheel which includes selecting a pressurized annular bladder, locating the bladder both axially and radially about the rim, forming a concentric bridge space having axial communication channels between the rim and bladder, and then pouring liquid urethane in a mold to form the tire.
摘要:
A multidirectional in-line roller skate (12) comprising a boot (14) to receive a foot of a skater (16). The boot (14) has a sole (18). A frame (20) is provided. A facility (22) is for securing the frame (20) to a bottom surface of the sole (18) of the boot (14). A plurality of spherical wheel assemblies (24) are also provided. A subassembly (26) is for mounting each spherical wheel assembly (24) in a removable manner to a bottom surface of the frame (20) centrally along a common place, so that each spherical wheel assembly (24) can rotate horizontally along a riding surface (28). An assemblage (30) is for revolving each spherical wheel assembly (24) vertically three hundred and sixty degrees in a clockwise and counterclockwise direction upon the riding surface (28), to allow the skater (16) to perform tight figure skating maneuvers on the riding surface (28).
摘要:
A novel skate platform wheel truck and wheel design is disclosed which permits reconfiguration of the wheels and truck to incorporate three wheels per truck, with a larger center wheel with a convex running surface, and smaller side wheels with a beveled edge. This configuration permits more fluid and responsive turning of the skateboard.

A balance board having a deck and a pair of parallel spaced rails supported on the deck. An underlying roller is rotatably mounted to a carriage having a pair of spaced wheel assemblies which rollingly engage respective ones of the rails. The roller engages the underside of the deck when the wheel assemblies engage the rails, and may be tapered to allow multi-directional use of the board.
摘要:
A wheel for an in-line skate includes a hub having a central core. First and second anchors extend radially from the core. The anchors are positioned on the core in spaced apart relation to define a material receiving volume between the anchors. A synthetic plastic material is molded to the core surrounding each of the anchors and filling the material receiving volume.
摘要:
The invention provides systems and methods for slowing or stopping a roller skate. In one exemplary system, a roller skate is provided having a frame with a longitudinal axis, a piece of footgear securely attached to the frame, and a plurality of wheels operably attached to the frame in alignment with the longitudinal axis. A braking mechanism is operably attached to the roller skate, with the braking system having a braking pad in alignment with the longitudinal axis. The braking pad is movable between a first position above a skating surface and a second position in contact with the skating surface. An actuator is provided which moves the braking pad between the first and the second positions while the angle of the skate relative to the skating surface remains constant.
