摘要： A skate wheel for an in-line skate includes a skate wheel hub having an inner hub, an outer rim, and, extending therebetween, a plurality of blade-form spokes. A skate tire is mounted upon an outer surface of the outer rim of the skate wheel hub. Opposed surfaces of adjacent blade-form spokes, in cooperation with opposed surfaces of the inner hub and the outer rim, define airflow passageways through the skate wheel. Each blade-form spoke includes a radially-aligned first spoke-edge surface exposed at a skate wheel face, a radially aligned opposite, second spoke-edge surface exposed in a region of a center plane defined by the skate wheel, and a body extending smoothly between the first and second spoke-edge surfaces. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.

摘要： An integral, one-piece, metallic chord for use as the top and bottom chords of a roof truss. The chord comprises an elongated member of generally U-shaped, singly symmetric cross-section, having a base terminating at its longitudinal edges in mirror image legs. The base portion is planar with a central depressed rib formed therein and extending the length thereof. Each leg comprises a first planar portion perpendicular to and extending from its respective longitudinal edge of the base, followed by an inwardly sloped planar portion leading to a planar attachment portion which is perpendicular to the base portion and which terminates in a flange portion extending outwardly of the attachment portion and then upwardly and inwardly, ending in a longitudinal edge facing the attachment portion. The flange portions form semi-closed reinforcement members. The legs and their flange portions constitute the sides of the chord. The first planar portion of each leg and the outermost part of the flange portion of each leg are co-planar, so that the chord will lie flat on either of its sides.

摘要： Disclosed is an in-line skate wheel that includes: (a) a braking portion including a high friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.45 to about 1.5; and (b) a skating portion including a low friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.1 to about 0.45. The skating portion includes a higher proportion of low friction surface material than the braking portion. The wheel delivers variable traction in response to the angle of wheel contact with the ground, without sacrificing a smooth ride or wheel durability. Utilizing the variable traction of the wheel a skater can stop safely and reliably, using known ice-skating maneuvers, wherein the wheel is turned away from the skater's direction of travel.

摘要： An improved fastener securing framing members to metal studs is provided. The fastener has rigid shank, an integral head, a self-tapping or drilling tip, and a first and a second spaced apart buttress threads. The shank has a generally circular cross-section and a longitudinally extending axis. The head integrally extends a first end of the shank and has a top portion and an underside. The self-drilling tip is extends from a second end of the shank. The first buttress thread is formed in said shank and is adjacent the head and partially traverses the shank, terminating from the shank's second end. The second buttress thread is formed in the shank and sufficiently spaced apart from the first buttress thread such that the first thread does not continue to threadingly feed the shank through an aperture formed by the self-drilling tip, the second buttress thread terminating adjacent the tip.

摘要： An in-line wheeled skate which includes one or more rollers located between the wheels and above the ground plane, thereby enabling the skater to jump up on a rail (or other supporting surface) and roll down the rail sideways, as in `extreme skating` maneuvers, by placing the skate on the rail with the rollers bearing upon the rail surface. The rollers may be, for example, cylindrical or spherical, and are preferably located between left and right side planes of the skate wheels.
