Sheet metal guide rail for an elevator system

摘要

A guide rail (14) for an elevator system (10) includes a base (20) connectable with a wall of a hoistway (12) of the elevator system (10) and a web section (24) connected to and extending from the base (20). A tip section (26) is located at an end of the web section (24) and is operably connectable to an elevator car (16) of the elevator system (10). The base (20), the web section (24) and the tip section (26) are formed of one or more thicknesses (28) of sheet metal material. An elevator system (10) includes an elevator car (16) located in a hoistway (12) and a guide rail (14) extending along the hoistway (12) and operably connected to the elevator car (16) for guiding the elevator car (16) along the hoistway (12). The guide rail (14) is configured such that braking forces applied to the guide rail (14) by a braking mechanism (36) successfully reduce the speed of the elevator car (16) without resulting in failure of the guide rail (14).

主权项

1. A guide rail for an elevator system in a hoistway, comprising:
a base connectable with a wall of the hoistway; a web section connected to and extending from the base, the web section having a web cross-sectional width; and a tip section disposed at an end of the web section and operably connectable to an elevator car of the elevator system, the tip section having a tip cross-sectional width greater than the web cross-sectional width; wherein the base, the web section and the tip section are formed of one or more thicknesses of sheet metal material and configured such that braking forces applied to the guide rail by a braking mechanism reduce the speed of the elevator car without resulting in failure of the guide rail; wherein the tip section includes a tip cavity disposed therein; and wherein the tip section includes a stiffener disposed in the tip cavity extending along an entire length of the guide rail to reinforce and provide rigidity to the tip section.
