Abstract: A trailer of the type for securing to and following a bicycle. The trailer includes a frame, a wheel rotatably mounted on the frame, and an extension member having first and second ends. The first end is hingedly connected to the frame such that the extension member is selectively positionable between an extended position wherein the extension member extends outwardly from the frame and a folded position wherein the extension member is disposed adjacent the frame for compactness of storage and transport.

Abstract: An in-line roller skate including a main chassis (1) supporting at least two rollers (5, 6), and an auxiliary chassis (8) which is articulated onto the main chassis and bears at least the rear roller (10). The skate includes a pair of discs (13) which are mounted so as to rotate and the frustoconical faces of which are applied onto the two rear rollers (6, 10) when the skate tilts rearward, braking being ensured by friction of the discs on the rotationally fixed parts of the skate.

Abstract: There is disclosed herein a suspension fork assembly particularly for use with bicycles. The assembly comprises an outer steer tube which is adapted to be mounted in and extend through the head tube of the bicycle frame, and an inner steer tube telescopes within the outer steer tube. A shock absorbing system is provided within the tubes. The inner surface of the outer steer tube and the outer surface of the inner steer tube each have a plurality of axially arranged opposing longitudinal flat sections, such as four on each tube. A plurality of needle bearings are disposed between the tubes on these flat sections. This arrangement, with the needle bearings arranged on the flat sections between the inner and outer tubes, allows the two tubes to freely telescope in and out with respect to one another without any significant static friction, and also serves to transmit the torsional steering force from the outer tube to the inner tube.
