Claims20
A flat elongated compensating member comprising:
- (a) a plurality of spaced apart strength members each with their respective axis arranged in a line and in substantially coplanar relationship with one another;
- and,
- (b) a jacket of flexible material containing a plurality of elongated spaced apart cavities therein, the axis of said cavitites arranged in a line and in substantially coplanar relationship with one another, each of said cavities containing at least one of said strength members and the volume of said cavities, not otherwise occupied by said strength member, substantially occupied by a mixture of metal particles and a plastic.
An elevator system comprising a car, a counterweight, a flat compensating member and a hoist rope, the hoist rope being connected to the car and the counterweight, the flat compensating member connected to the counterweight and the car, the improvement wherein said flat compensating member is composed of:
- (a) a plurality of spaced apart strength members each with their respective axis arranged in a line and in substantially coplanar relationship with one another;
- and,
- (b) a jacket of flexible material containing a plurality of elongated cavities therein, the axis of said cavities arranged in a line and in substantially coplanar relationship with one another, each of said cavities containing at least one of said strength members and the volume of said cavities, not otherwise occupied by said strength member, substantially occupied by a mixture of metal particles and a plastic.
