PROBLEM TO BE SOLVED: To realize an economical elevator capable of simplifying its installation and maintenance and updating an existing elevator provided with constituent elements of this elevator easily and quickly. SOLUTION: This invention relates to the elevator, a maintenance method for the elevator, a method for updating the elevator, and a clamp device for the elevator. This elevator has a cage and a suspension means or respective hoisting means 1 for carrying an operation weight. A power transmission means 2 moves the suspension means and the hoisting means over at least one moving surface 20 of the power transmission means 2. The power transmission means and the suspension means or respectively hoisting means are a rope-shaped and/or belt shaped. The power transmission means and the suspension means or each winding-up means are physically separated from each other. The power transmission means and the suspension means or respectively hoisting means are physically separated from each other. The power transmission means and the suspension means or respectively hoisting means are stretched against at least one supporting body 3. COPYRIGHT: (C)2004,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide fixing points for fixing a cable, and an elevator having the fixing points for cable ends and transporting a load carrier by the cable movable in a longitudinal direction. SOLUTION: The cable fixing points 12, 13 comprise cable end fastenings 50 for cable ends 7', 7'' of the cable 7, and rotary mounting parts 40 for the cable end fastenings, wherein each rotary mounting part allows the rotation 46 of the cable end fastenings around an axis L, and the axis can be aligned with a tension force F applied to the cable. The fixing points are used for fixing one end of the cable, and the cable at the cable end is disposed under the tension force, the direction α of which is variable according to the position of the load carrier. The cable is rotatable at the cable fixing points around the axis L aligned in each direction of tension force and/or in the respective longitudinal directions of cable segments 7.1, 7.5 adjoining the cable fixing points.

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 a countermeasure against the transmission of energy and/or a signal to a movable door leaf of an elevator door drive, without impairing convenience of a user, by guaranteeing availability of a high level, by requesting a minimum space in the door leaf. SOLUTION: This door drive 10 has a drive unit 12 and a belt-like drive means 11 for moving the door leaves 14.1 and 14.2. Conductive elements 15.1 to 15.n extending in the longitudinal direction of the drive means and transmitting the signal or the energy, are arranged in the drive means. A first contact means 16 is arranged in an area of the drive means. The drive means has a longitudinal directional groove capable of making access of the first contact means to the conductive elements. The first contact means travels by passing through the first contact means when the drive means moves, and is constituted so that the first contact means generates permanent contact with the conductive elements.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for avoiding defects of known devices, and a system and a method for assuring generation of elevator shaft information usable for elevator control in any case. SOLUTION: In the system for generating the elevator shaft information, an image of a surface of a guide rail 1 is recorded using a CCD linear camera 3, and an absolute position of an elevator cage is determined based on a surface pattern read from the image. Image data is inputted to a first correlation device I using an increment position of a new image and an absolute position i of a preceding image to generate an estimated position to be inputted to a second correlation device II. The estimated position is used for searching a related data base sector where an image stored in a data base is positioned at the time of calibration. The second correlation device II compares the new image with the stored image, and determines the absolute position i+1 to be transmitted to an elevator control means based on a position index of the stored image.
Abstract:
The invention relates to a lift (1) comprising at least one belt (11) which is used as a carrier or a drive means and is provided with a 2:1 belt guide. When the mechanical linear drive (12), which is arranged laterally in the shaft head (2.1), drives the belt (11) one unit forward by encircling it around a drive wheel (13), the lift cage (3) or the counter weight (4) is displaced by half a unit. One of the extremities of the belt (11) is arranged at a first fixed point (14) of the belt and the second extremity of the belt (11) is arranged at a second fixed point (15) of the belt. The belt (11) is guided via a first deflection roller (16), a profile roller (17), a second deflection roller (18), a third deflection roller (19), via the drive wheel (13) and via a fourth deflection roller (20). Deflection rollers (22) of the linear drive (12) determine the angle of encirclement of the belt (11) on the drive wheel (13).

A lightweight glass plate includes a first glass plate, a second glass plate and an intermediate layer that connects the first and the second plates together. The lightweight glass plate further includes at least one connection element that allows the lightweight glass plate to be connected to an abutting component. The connection element is embedded into the intermediate layer in an edge area of the lightweight glass plate and the intermediate layer extends to surfaces located between the connection element and the glass plates. The lightweight glass plate is preferably used in the preparation of elevator doors and/or car walls. The lightweight glass plates are lightweight and can transfer large forces.
Abstract:
A door drive has a drive unit and a belt-like drive for moving at least one door leaf. At least one electrically conductive element extends in a longitudinal direction of the belt-like drive for transmission of electrical signals or energy to/from the at least one door leaf. A first contact device extends into a longitudinal groove formed in the belt-like drive enabling access to the at least one electrically conductive element. When the belt-like drive is moving past the first contact device, the first contact device produces a permanent contact with the at least one electrically conductive element.
