Embodiment Construction

[0019] FIG. 1 schematically shows selected portions of an elevator car 20 . The structure of the cab 20 includes a floor 22 , a ceiling 24 , and side walls 26 and 28 . In this frameless car example, side walls 26 and 28 of car 20 each include at least one sheet 32 ​​supporting a roller guide assembly 30 for guiding elevator car 20 along guide rails 31 of the mobile. The sheet 32 ​​may be the upright of the car 20 and may be formed by bending and / or folding a sheet of steel into the desired shape. The car may alternatively include a frame (not shown) supporting the car 20, and the sheet 32 ​​may be part of the frame.

[0020] The car (framed or frameless) and guide rails 31 may be part of an elevator system which may include (but not shown) a counterweight, ropes for suspending and driving the car and / or counterweight, and machines that drive the traction sheave to move the rope and convey the car and / or counterweight.

[0021] The roller guide assemblies 30 each include a ...

Abstract

The invention discloses an elevator system component capable of vertically moving. The elevator system component comprises a top, a bottom and multiple vertical oriented side parts between the top andthe bottom, wherein at least one of the side parts comprises a roller guide support sheet; a first roller guide roll is supported by the sheet, so that a first roller is at least partially arranged on the first side of the sheet, and the axis of the first roller is roughly equal to the sheet; a second roller and a third roller are supported by the sheet, so that the second roller and the third roller are located on the second opposite side of the sheet; the axis of each of the second roller and the third roller is roughly perpendicular to that of the first roller; and the axis of each of thesecond roller and the third roller is kept in the fixed position relative to the sheet.

Description

[0001] This application is a PCT patent application submitted on February 24, 2014 that has entered the Chinese national phase (Chinese national application number is 201180073027.8, international application number is PCT / US2011 / 048916, and the invention name is "elevator roller guide") Divisional application. Background technique [0002] Elevator systems include various components to ensure the system works as intended. Some type of guide is associated with the elevator car and counterweight to guide the movement of the car and counterweight along the guide rails. Many elevator guides include rollers that roll along surfaces on the rails as the elevator car moves up and down. Other guide assemblies include sliding elements that slide along the surface of the guide rail. [0003] There are known reasons for choosing rollers or sliding elements for elevator guides. Sliding guide elements are usually chosen for installations involving space constraints since guides comprisi...
