Abstract: The invention discloses a technology to safely control speed and brake on in-line skates using a ski-like technique, wherein in-line skate wheels can rotate both vertically and at an angle. When angled (or “canted”) the wheels contact a friction strip within the wheel frame or a friction disk on the axle. The friction caused by the angled wheels contacting friction strips or friction disks is comparable to the canted “edging friction control” action of skis. The novel means that allows both vertical and angular rotation is a cohesive 2-element plastic hub shown in FIG's 1–C & D. The inner element 2a has a convex perimeter and fits inside outer element 2's convex bore, allowing 2a to rotate freely within outer element 2. Within inner element 2a are axle bearings 5 or 9 and axle 8. External elastomer springs 7a or internal elastomer spring 7b keep each wheel in a vertical coasting position.

Abstract: A skate wheel including a tire support structure adapted to reduce roll resistance generally encountered from a tire comprising a 60 A to 75 A Shore hardness material. The tire support structure comprises a flexible torus portion proximal to an inner core, and a substantially rigid radially extending portion extending radially outward from the flexible torus portion. The flexible torus portion cooperates with the inner core to form a cavity. The radially extending portion extends to approximately eighty to ninety five percent of the total wheel diameter. When a load is placed on the wheel, the radially extending portion is pressed against the flexible torus portion, and the flexible torus portion deforms into the cavity. The combination of the radially extending portion and the flexible torus portion moderates distortion of the soft tire, thereby reducing roll resistance.

The skew-mounted illuminating devices allow the skate wheel to be fitted on in-line skates and skate boards that can only use small wheels. Further, the present design can prevent scratching of the illuminating devices against the ground that would otherwise cause abrasion on the surface of the illuminating devices and attenuate the light given out by the illuminating devices.

Abstract: A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms. The pivot arms are biased forward which is in a clockwise direction with respect to their pivot point. When skating normally, the pivot arms bias the wheel against the brake pad, but the wheel is elevated from the skating surface and thus the brake is not engaged. When skating in a rearward direction, or desiring a push start, the skater rotates the toe portion of the skate downward and raises the heel. The front wheel will engage the skating surface and the reaction force on the wheel due to friction between it and the skating surface will urge the wheel forward and increase the contact pressure between it and the brake pad.
