Abstract:
PROBLEM TO BE SOLVED: To provide a support drive means of a synthetic fiber cable by appropriate transmission of tensile force from a strand layer to another strand layer. SOLUTION: In this synthetic fiber cable 1, the strands of the strand layer are mutually spaced apart. With the mutual spacing d1, the strands 7 of the outer strand layer 2 can move radially in the direction of the cable center and exert a radial pressure on the strands 8, 9 of the first inner strand layer 3. The radial pressure is passed on from the strands 8, 9 of the first inner strand layer 3 to the strands 10 of the second inner strand layer 4. The radial pressure is passed on from the strands 10 of the second inner strand layer 4 to the core strand 5. The radial pressure increases inwardly from strand layer to strand layer. The soft cable sheathing 6 does not act as a support between the strands 7 in circumferential direction Ur. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To create a support driving means which keeps a flexure stress lower in a tension carrier. SOLUTION: The support driving means (11) has a geometric form of a belt made up of a belt main body (12) or a sheath (12) which surrounds the tension carrier (1). A belt running surface (16) is flat and can be parallel with a backside (13) of the belt or can have a trapezoidal or semi-circular rib (14) and a groove (15). A contour of a driving pulley or a biasing pulley is approximately complementary with the belt running surface. One or more tension carries (1) are provided for each rib (14) and the tension carriers (1) are twisted alternately or together in Z and S directions. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an optimized support means end connection part certainly transmitting baggage-resistance force of a support means at a maximum. SOLUTION: This invention relates to the support means end connection part for fastening the support means end in the elevator device. The support means comprises a cable or a cable strand; and a cable casing for surrounding the cable or a cable strand composite body. According to the invention, the cable casing substantially comprises a thermoplastic synthetic material or an elastomer and the cable or the cable strand is adhered, fused or mechanically connected to the cable casing at an area of the support means end connection part. Friction force transmitted from the support means end connection part to the cable casing is directly transmitted to a core receiving load of the support means and is directed to the cable or the cable strand. Allowable tension in the support means is increased. The support means preferably comprises a large number of cables. COPYRIGHT: (C)2007,JPO&INPIT
