Abstract
A tensioning device for an elevator air cord that forms a loop has: a support having a relatively accessible first surface and a relatively inaccessible second surface; a holder on the second surface for fixedly holding a first end of the air cord; a tensioning device on said second surface for holding a second end of said air cord such that the tension of the loop of air cord may be adjusted; and key communicating between the first and second surfaces for manipulating the tensioning device to adjust the tension of the air cord loop.
Claims9
A device for adjusting the tension of an elevator air cord forming a loop, characterized by;
- a support having a relatively accessible first surface and a relatively inaccessible second surface;
- a holder on the second surface for holding a first end of the air cord;
- a tensioning means on said second surface for holding a second end of said air cord such that the tension of said loop of air cord may be adjusted by moving said second end towards said first end;
- and
- means communicating between the first and second surfaces for manipulating the tensioning means to move said second end towards said first end.
A device for adjusting the tension of a cable forming a loop, characterized by;
- a support having a relatively accessible first surface and a relatively inaccessible second surface;
- a holder on the second surface for holding a first end of the air cord;
- a tensioning means on said second surface for holding a second end of said air cord such that the tension of said loop of air cord may be adjusted by moving said second end towards said first end;
- and
- means communicating between the first and second surfaces for manipulating the tensioning means to move said second end towards said first end.
