Abstract:
PROBLEM TO BE SOLVED: To provide a door frame capable of facilitating maintenance and mounting, being not an eyesore, and having a control unit manufacturable at low cost and to provide a method for accessing a control unit in the door frame. SOLUTION: This door frame 14 of the passage door is provided with the control mechanism for elevator facility having the elevator passage 11 and the control unit 18, and the control unit is a part of the control mechanism. The control unit 18 is fixed and arranged in a chamber 16 of a door frame member 14.1 of the door frame 14. The chamber 16 has an outer side opening, which is opened at a story 9 and has a cover 17. The cover 17 can move from an operation position where the outer side opening is closed by removing the cover from a service position completely. It can access the chamber 16 freely at the service position. The door frame 14 has an inner side opening 16.21 allowing access from the elevator passage 11. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an evacuating device of an elevator's passenger allowing even an unexperienced person to move an elevator car to a next floor by releasing a brake of an elevator driving device. SOLUTION: This device equips with a handle 4.2 with which the brake 4.4 can be manually released. After the brake 4.4 is released, the elevator car 2 moves upward or downward depending on weight difference between the elevator car 2 and a balance weight 2.1. A position of the elevator car 2 in an elevator hoistway 1 is important for an elevator controller 4. A toothed belt 10 expanded over the length of the hoistway contacts with an encoder 11 for detecting an absolute position of the elevator car 2. A signal device is provided for allowing evacuation without looking at the inside of the elevator hoistway 1 for the evacuation.
Abstract:
A brake monitor for monitoring a brake system of an elevator system that includes a drive and a drive controller checks for a travel signal generated by the elevator system. If a brake-release signal is not received within a time-window after the occurrence of the travel signal, the brake monitor activates a relay circuit for interrupting a safety circuit of the elevator system or for interrupting a control voltage of the drive controller so that the elevator system can be stopped.
Abstract:
An elevator drive (1.1) with traction sheave (1.2) over which ropes (1.3) are passed moves an elevator car (2) and a counterweight (2.1) up and down in an elevator hoistway (1). An elevator control (4.1) arranged in a control cabinet (4) on a landing (E2) is connected with an elevator control (1.4) and with the elevator car (2), and controls how the elevator car (2) moves. Arranged in a control cabinet (4) is also a handle (4.2) which is part of a Bowden cable (4.3), the Bowden cable (4.3) acting on a brake (4.4) of the elevator drive (1.1). There is a handle (4.2) with which the brake (4.4) can be released manually. With the brake (4.4) released, the elevator car (2) moves up or down depending on the difference in weight between the elevator car (2) and counterweight (2.1). For the elevator control (4) the position of the elevator car (2) in the elevator hoistway (1) is of significance. A tensioned toothed belt (10) spanning the height of the hoistway is in contact with an encoder (11) which detects the absolute position of the elevator car (2). For evacuation, a signal device is provided which allows evacuation without looking into the elevator hoistway (1).
Abstract:
The sliding door for a lift shaft (11) has a door leaf (12.1) which slides across so that its edge closes the gap between itself the edge of a frame (16) containing the box (18). The box is accommodated in a vertical frame member (14.1) extending from the floor to the top of the frame opening. There is a floor indicator (20) on the front of the box and an access lid (17) on the side. The frame member has a joggle and the width at the front (16.1) is greater than the width (16.21) of the side facing the shaft.

Abstract:
Brake monitor (100) for monitoring a brake system (13) of an elevator system (10) that comprises a drive (11) and a drive controller (12) in addition to the brake system (13). The brake monitor (100) comprises a first brake signal input (KB) for electrically connecting the brake monitor (100) to a first brake contact of the brake system (13). The brake monitor further comprises a driving signal input (AF) for connecting the brake monitor (100) to a first electrical driving signal line (12.1) of the drive controller (12). Also provided are a power supply (101), a microprocessor (102) and a relay circuit (103). The relay circuit (103) is configured such that it can be activated for interrupting a safety circuit (20) of the elevator system (10) or for interrupting a control voltage of the drive controller (12) so that the elevator system (10) can be stopped.

An elevator drive has a traction sheave over which ropes are passed to move an elevator car and a counterweight up and down in an elevator hoistway. An elevator control in a control cabinet on a landing is connected with another elevator control in the hoistway and with the elevator car, and controls how the elevator car moves. The control cabinet also has a handle that is part of a Bowden cable acting on a brake of the elevator drive. The handle can be used to manually release the brake which permits the elevator car to move up or down depending on the difference in weight between the elevator car and the counterweight. The position of the elevator car in the hoistway is of significance to the elevator control. A tensioned toothed belt spanning the height of the hoistway is in contact with an encoder that detects the absolute position of the elevator car for the elevator control. For evacuation, a signal device is provided which allows evacuation of the car without looking into the elevator hoistway.
