Abstract
A sway reduction device having a cable receiving section, the cable receiving section being formed of a shock-absorbing material and comprising a flexure portion and an aperture for receiving a cable therethrough. The sway reduction device also includes a mounting section with subsections and at least one mounting member for mounting the sway reduction device to a surface. The subsections are moveable generally toward and away from each other whereby the flexure portion is flexed when the subsections are moved away from each other for installing the sway reduction device around a cable.
Claims42
An elevator system comprising:
- an elevator car;
- a counterweight;
- an elevator compensating cable operably engaged between the elevator car and the counterweight, the elevator compensating cable being adapted to be at least partially disposed in spaced and substantially parallel relation to a wall disposed adjacent to the elevator car;
- and
- a sway reduction device operably engaging the wall and for receiving the elevator compensating cable therethrough, the sway reduction device comprising:
- a cable-receiving structure having opposed engagable distal portions and a flexible medial portion with at least the distal portions being comprised of a flexible shock-absorbing substance so as to be capable of at least partially dissipating an impact energy resulting from contact of the elevator compensating cable with the cable-receiving stricture, the medial portion being configured to define an aperture upon engagement of the distal portions such that the aperture defines an axis, the cable-receiving structure being configured to receive the elevator compensating cable within the aperture through the distal portions and such that the elevator compensating cable is capable of passing freely through the aperture in the axial direction, the distal portions being configured to correspondingly engage so as to extend transversely in substantially perpendicular relation to the aperture axis;
- and
- a mounting member extending from each distal portion so as to be disposed perpendicularly to the aperture axis, the mounting members being configured to extend in substantially the same direction upon engagement of the distal portions and being adapted to engage the wall so as to secure the cable-receiving structure thereto.
A sway reduction device adapted to operably engage a wall having an elevator compensating cable at least partially disposed in spaced and substantially parallel relation thereto, the sway reduction device comprising:
- a cable-receiving structure having opposed engagable distal portions and a flexible medial portion, the medial portion being configured to define an aperture upon engagement of the distal portions such that the aperture defines an axis, the cable-receiving structure being configured to receive the elevator compensating cable within the aperture through the distal portions such that the elevator compensating cable is capable of passing freely through the aperture in the axial direction, at least the distal portions being comprised of a flexible shock-absorbing substance so as to be capable of at least partially dissipating an impact energy resulting from contact of the elevator compensating cable with the cable-receiving structure, the distal portions further being configured to correspondingly engage so as to extend transversely in substantially perpendicular relation to the aperture axis;
- and
- a mounting member extending from each distal portion so as to be disposed perpendicularly to the aperture axis, the mounting members being configured to extend in substantially the same direction upon engagement of the distal portions and being adapted to engage the wall so as to secure the cable-receiving structure thereto.
