PROBLEM TO BE SOLVED: To provide a reliable solving measure used for a lift installation for preventing pulling-up of an empty or near empty lift cage called overrunning. SOLUTION: This lift installation 10 has a support means 13 and a driven drive pulley 16 driving the lift cage 11. The support means 13 is wound at least partially around the drive pulley 16, and also has a safety part 17. This safety part 17 is constituted so that the safety part 17 interacts with the drive pulley 16 when the lift cage 11 or a counterweight 12 approaches the upper elevator hoistway end 14.1 after overrunning in an upper position X. The safety part 17 is formed so as to generate " a slip " by interaction of the driving pulley 16 and the support means 13. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an optimized support means end connection part. SOLUTION: This invention relates to the elevator device having the support means end connection part and support means and the method of fastening the support means 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. The support means is retained in a wedge pocket by a wedge. According to the invention, the cable casing of the support means substantially comprises a thermoplastic plastic material or an elastomer. A wedge groove in a longitudinal axis direction is provided at an area of the wedge or an area of the wedge pocket and/or a means for reducing friction coefficient is provided at an area of the support means end connection part at an area of the wedge or an area of the wedge pocket or an area of the cable casing. The support means preferably comprises a large number of cables. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an improved elevator system, widely using a belt, one side of which is shaped. SOLUTION: A roller device includes two rollers 10, 20 having rotating shafts 12 or 22 and substantially parallel to each other. The rollers 10, 20 have structured outer peripheral surfaces 13, 23 including a parallel roller rib17.1 and a roller groove 17.2 and the rollers are reversed when an elevator car is moved. The belt 30 forms an under loop to support the elevator car, travels directly from the roller 10 to the roller 20, and the roller structures 10, 20 have a complementary structured belt main surface 33. In an area A disposed between two rollers 10, 20, the belt 30 is twisted round the vertical axis 32 of the belt, whereby when the belt 30 travels on the reversed rollers 10, 20, the main surface 33 of the belt is engaged with the outer peripheral surfaces 13, 23 of the two rollers 10, 20.

Abstract:
PROBLEM TO BE SOLVED: To create a further miniaturizable elevator device by avoiding a disadvantageous point of a publicly known apparatus. SOLUTION: In this elevator, deflection rollers 16, 18 and 20 are integrated into a cage floor 21 or a counterweight 4. A support driving means 11 is guided by the cage floor 21 by passing through a floor channel 21.1. When compared with a conventional cage floor having the deflection roller (a bottom part block) arranged under the cage floor 21, the cage floor 21 is made so that the whole height is very low, and this imparts the direct effect to the depth 8 of an elevator shaft pit. The height provided by the cage floor 21 can reduce the depth 8 of the elevator shaft pit. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an elevator device in which the possibility of failure due to damage to a belt is suppressed. SOLUTION: The belt 12 for the elevator device comprises a first partial belt 13 made of a first material, a tension support body mechanism having at least one tension support body 14 and disposed on the first partial belt, and a second partial belt 15 made of a second material. The first material has a thermoplastic resin material for accepting and distributing a local surface pressure introduced into the belt by the tension support body. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To use an elevator belt in which only a small elastic deformation occurs in the wedge-like rib. SOLUTION: This elevator belt 12 of an elevator device comprises a wedge-like structure 15 extending in the longitudinal direction of the elevator belt and having at least two wedge-like ribs 15.1 forming contact side surfaces for engaging with the drive wheel 4.1 of the elevator device, a tension supporter structure 14 having at least two tension supporters 14.1, 14.2 disposed on two wedge-like ribs of the wedge-like rib structure adjacent to each other, and a rear surface layer 13 forming the rear surface of the elevator belt. The rear surface layer has an outline in which at least one web 13.1 projecting toward the contact surface is formed in the wedge-like structure. COPYRIGHT: (C)2008,JPO&INPIT
