  • Publication number: 20100290726
    Abstract: In order to provide a plain bearing, in which the efficiency in particular in the case of dry-running is increased and which in particular in these conditions also tolerates higher than previously usual running speeds over long periods of operation, it is proposed that the plain bearing has a bearing body, in which a bearing bush is configured, the surface of which is produced at least in some areas from a plastic material, wherein the plastic material comprises a fully fluorinated thermoplastic polymer material, optionally compounded with a proportion of one or more further high-performance thermoplastics selected from polyether ketones, polyphenylene sulphide (PPS), polyphenylene sulphone (PPSO2), polyamide (PA), polyimide (PI), polyamide-imide (PAI) and/or polyether imide (PEI), as well as copolymers and derivatives of these polymers and copolymers.

  • Patent number: 7316411
    Abstract: A board for gliding over snow, more particularly for children, includes a structure made of just one homogeneous material of an injected thermoplastic polymer, two metal side edges with wings, bordering the bottom surface forming the gliding surface. The structure includes a top surface and a bottom surface forming a gliding surface, and defines a hollow volume. The wings of the metal side edges are embedded in the homogeneous material of an injected thermoplastic polymer material of the structure.

  • Ski
    Patent number: 7083183
    Abstract: A short ski (1) having a length LT of less than 110 cm, in particular for skiing by children, having a reduced-thickness region (3) in its central zone (2), which is bounded at the front and the rear by maximum-thickness regions (4, 5) each capable of holding the elements (6, 7) of a safety binding, said ski having an overall flexibility (SG), that is to say a flexure under deformation by a force F of 20 decanewtons applied to the upper surface of the ski midway between the two supporting points respectively lying level with the front contact line (LCFR) and rear contact line (LCRE), which is between: L p 3 H max 2 × 10 - 5 ? ? and ? ? L p 3 H max 2 × 2.10 - 5 expressed in millimeters, where Lp is the bearing length as defined between the front and rear contact lines and Hmax is the maximum thickness of the ski, both expressed in millimeters.

  • Publication number: 20050161909
    Abstract: A board for gliding over snow, more particularly for children, comprises a running surface forming a bottom-surface element (6) bordered by two metal side edges (8) with wings (18), a top surface (7) and a core (13) defined between the running surface (6) and the top surface (7), produced by injection of a thermoplastic polymer material, said core (13) having a hollow volume (14). The running surface forming the bottom-surface element (6) is produced with the polymer material of the core (13). The wings (18) of the metal side edges (8) are embedded in said polymer material of the core (13) and of the running surface forming the bottom-surface element (6).
