A front wheel can be provided with two springs the longitudinal axes of which are oriented in the extent between the horizontal and vertical directions with the bottom ends of the springs being placed in front of the top ends of the springs or under them. Other wheels may be equipped with four springs having the longitudinal axes of the spring oriented vertically. At least two wheels can be provided with a braking system including clips with brake pads on both sides. The roller skate may be used and maintained on a specially configured assembling stand.

Abstract: An improved braking system is disclosed in which a pair of conical braking members engage a pair of skate wheels through vertical movement of a pushrod that is actuated by movement of the skater's foot within a cuff. The braking members are separated by a spring disposed on an axel to maintain the braking members in optimal braking position. The braking members are serrated to promote frictional contact with the wheels, and a disk is positioned on the axel to act as a clutch to control the braking force.

Abstract: In-one aspect, a leg activated brake for a foot supporting rolling device, such as a roller ski. Roller skis generally have one wheel mounted to each end of the foot supporting frame which houses a ski binding for the skier's boot. The brake system mounts to the frame of the roller ski and when the brake is activated by the leg, the brake applies frictional force to the rear wheel to stop the roller ski.

Abstract: An in-line skate which includes a plurality of wheels mounted to a frame each having a primary contact surface which contacts a skating surface to support the skater when the skate is in a generally upright position, and at least one secondary rotatable contact surface disposed at a level above the primary contact surfaces when the skate is in a generally upright position and positioned to contact the skating surface only when the in-line skate is inclined beyond a selected angle from the vertical. The length of the wheelbase formed by the secondary contact surface is shorter than the length of the wheelbase formed by the primary contact surfaces. By effectively changing the length of the wheelbase of the in-line skate when the in-line skate is at a certain angle from the vertical, a tighter turning radius may be achieved.

Abstract: A skate brake particularly suited for an inline skate includes a braking carriage formed of left and right plates spaced apart by axles that support rollers thereon. The rollers engage the wheels of the skate when the carriage is maneuvered to the appropriate elevation, and the momentum of the wheels is arrested as a result of a frictional bearing of the rollers against the carriage surface. The carriage is raised and lowed by a rocker mounted below the skate and coupled to the carriage plates, where rotation of the rocker drives the plates and the carriage downward such that the rollers contact one or more wheels. The rocker is actuated by a linkage that includes a pushrod and a second rocker that is mounted to the skate boot, allowing the user to control the braking carriage by applying pressure to a rear location of the boot.

Abstract: An inline skate with a braking system has a boot and a braking assembly. The boot has a bottom, a rear end and rollers. The rollers are rotatably mounted on the bottom of the boot. The braking assembly is pivotally mounted on the bottom near the rear end of the boot. When the braking assembly abuts the ground, the braking assembly pivots toward the rollers of the boot to stop the rotation of the rollers of the boot so that the ground does not have a trace of the stain. The total length of a combination of the boot and the braking assembly can be short so that a skater has a smooth movement when the skater is skating and the inline skate has better control. The inline skate with shorter length has a neat appearance.
