Abstract:
PROBLEM TO BE SOLVED: To provide an elevator cage reducing bending moment around a point through which a pulley box is mounted to the cage. SOLUTION: The elevator cage 1 comprises a car 2, a support member 6 connected to the car 2, and the pulley box 8 housing a pair of pulleys 9 mounted to the pulley box 8 by pulley axles 10, wherein the pulley box 8 is mounted to the support member 8 through one or more points located below a first line P bisecting the pulley axles 10 and above a second line Q defining a lowest common tangent between the pulleys 9.

Abstract:
PROBLEM TO BE SOLVED: To propose an elevator car having a structure of a car wall, and having no conventional problem of a device cited as a conventional technology. SOLUTION: This elevator car 2 has adjacently arranged wall panels (4.1 and 4.2). Two joining elements (7.1 and 7.2) exist in areas of adjacent end surfaces (9.1 and 9.2) of the wall panels (4.1 and 4.2). One is fixed to the main surface (8.1) of the first wall panel (4.1), and the other is fixed to the main surface (8.2) of the second wall panel (4.2) existing on the same plane. The respective joining elements (7.1 and 7.2) also overlap with the main surface of the wall panel unfixed with the joining element. Among the joining elements (7.1), one has an oblique boundary surface (10). and the other joining element (7.2) has the opposed contours (11) sliding on the oblique boundary surface (10) when the wall panels (4.1 and 4.2) are arrayed.

Abstract:
PROBLEM TO BE SOLVED: To provide a lift cage having no conventional problems, and to provide a maintenance method. SOLUTION: The lift cage 1 comprises a cage roof 2 which can be lowered to a passenger compartment by a lifting device and which is functioned as a maintenance platform for a maintenance worker to do maintenance work at a lowered position. The lifting device has several Bowden pulls. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A method for carrying out maintenance and inspection operations at an elevator installation with an elevator car having a lowerable car roof that serves as maintenance platform, comprises at least the following steps: positioning the elevator car at a selected floor and opening the elevator doors; lowering the car roof into the elevator car to work level; climbing of the maintenance person with the help of climbing equipment from the selected floor through the elevator doors onto the lowered car roof, closing the elevator doors; and moving the elevator car to maintenance positions.
Abstract:
A load carrying means (1) for cable operated elevators comprising an under loop cable arrangement is equipped with a load measurement device, at least one of the pulleys (9) mounted underneath the load carrying means (1) is fixed to said load carrying means (1) by a support structure (7) containing an elastic element (7.1, 16, 22) which is deformed by the load dependant cable forces (14) exerted on the pulley(s) (9). A single sensor (15, 16) determines the extent of this deformation and produces a corresponding signal representing the weight of the load carrying means (1) as the input for the elevator control system.
Abstract:
The cabin has cabin walls with wall units (4.1, 4.2) arranged in parallel, and two connecting units (7.1, 7.2) provided in an area of front surfaces (9.1, 9.2) of the wall units. The connecting unit (7.1) has a limitation surface (10) slanting to longitudinal direction of the front surfaces of the wall units. The connecting unit (7.2) has a counter-contour, which slides when joining the wall units along the slided limitation surface. The wall units are provided in a form of connection plates, metallic plates or plastic plates. An independent claim is also included for a method for installing wall units of an elevator cabin.
Abstract:
The present invention provides an elevator cage 1 comprising a car 2, a support member 6 connected to the car 2, and a pulley box 8 housing a pair of pulleys 9 mounted to the pulley box 8 by pulley axles 10, wherein the pulley box 8 is mounted to the support member 6 through one or more points located below a first line P bisecting t he pulley axles 10 and above a second line Q defining a lowest common tangent between the pulleys 9.
Abstract:
A load carrying and measuring apparatus for cable elevators includes a support construction attached to an underside of a base frame or a carrier frame for an elevator car and a pair of cable rollers attached below the support construction for engaging a support cable. A resilient element attaches at least one of the cable rollers to the support construction whereby the resilient element is deformed by load-dependent cable forces acting through the cable roller. A sensor detects the deformation of the resilient element and sends a signal to the elevator control. A resilient isolating element can be connected between the support construction the base frame or the carrier frame.
Abstract:
A load-carrying means (1) for cable-operated elevators comprising an under- loop cable arrangement is equipped with a load measurement device. At least one of the pulleys mounted underneath the load-carrying means (1) is fixed t o said load-carrying means by a support structure containing an elastic elemen t (7.1, 16, 22) which is deformed by the load-dependant cable forces exerted o n the pulley(s) (9). A single sensor (15, 16) determines the extent of this deformation and produces a corresponding signal representing the weight of t he load-carrying means (1) as the input for the elevator control system.
