US 11,447,367 B2 · Magnetic tape stabilizing systems

Abstract

A stabilizing system may be utilized to reduce or eliminate sway of magnetic tape that is suspended in an elevator hoistway and provides a positional reference to an elevator cab. The stabilizing system may include a stabilizing mechanism fixed within a hoistway and a roller cam disposed on the elevator cab. The stabilizing system may include a telescoping member attached to a guide having opposing flanges that restrict movement of the tape. The telescoping member and the guide may be biased in an extended position, where the guide partially surrounds the tape. In a retracted position, the guide is horizontally spaced apart from the tape. When the elevator cab passes the stabilizing mechanism, the roller cam may force the guide and the telescoping member into the retracted position to prevent any contact between the stabilizing mechanism and components disposed on the elevator cab.

Dependent claims

A stabilizing system comprising:

a stabilizing mechanism that is configured to be fixed within an elevator hoistway, the stabilizing mechanism including:
a telescoping member,
a mount for the telescoping member, wherein the telescoping member is positionable in a retracted position and in an extended position relative to the mount, and
a guide disposed on the telescoping member, the guide being configured to partially surround and stabilize tape suspended in the elevator hoistway when the telescoping member is in the extended position;
and
a roller cam that is configured to be disposed on an elevator cab, wherein the roller cam is configured to force the telescoping member from the extended position into the retracted position when the roller cam engages with the stabilizing mechanism.
