Publication number: 20170362059Abstract: A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave.Type: ApplicationFiled: May 2, 2017Publication date: December 21, 2017Inventors: Pedro S. Baranda, Ary O. Mello, Hugh J. O'Donnell

Patent number: 9010495Abstract: An elevator sheave (20) includes a belt guiding surface (26) having a surface profile along at least a portion of the belt guiding surface. The surface profile preferably is defined by an nth order polynomial equation where n is a number greater than 2. In one example, the reference point (40) is a central point along the width of the belt guiding surface (26). In one example, a central portion (42) of the surface profile preferably is aligned to be generally parallel with the central axis (34) of the sheave body. Some examples have curvilinear side portions (44,46) between the central portion (42) and the edges (28,30) of the sheave. Other examples also include second side portions (48,50) that have linear profiles.Type: GrantFiled: August 4, 2004Date of Patent: April 21, 2015Assignee: Otis Elevator CompanyInventors: Dilip Prasad, Brice N. Cassenti, Pedro S. Baranda, William Veronesi, William C. Perron, Ary O. Mello, Jr., Paul A. Stucky, John T. Pitts, John P. Wesson, Mark S. Thompson

Patent number: 8734203Abstract: An illustrative method of making a load bearing member for use in an elevator system includes mechanically roughening at least one surface on an exterior of a jacket of the load bearing member to establish a friction characteristic that facilitates engagement between an elevator system sheave and the roughened surface.Type: GrantFiled: May 3, 2013Date of Patent: May 27, 2014Assignee: Otis Elevator CompanyInventors: John T. Pitts, Ary O. Mello, Hugh J. O'Donnell, John P. Wesson, William A. Veronesi, Douglas E. Logan, Mark Steven Thompson, Kathryn Rauss Sherrick, Bill Perron

Patent number: 8449349Abstract: An elevator load bearing member assembly includes at least one roughened surface (46) on a polyurethane jacket (44). In one example, mechanical roughening is used to roughen the surface (46) after the jacket has been extruded onto tension members (42). In another example, the temperatures used for molding a jacket (44) are controlled to induce melt fracture and roughen the surface (46) during the forming process. Other examples include chemically roughening the jacket surface and using localized heating to roughen the surface. The roughened jacket surface improves friction characteristics of a load bearing member assembly.Type: GrantFiled: March 15, 2004Date of Patent: May 28, 2013Assignee: Otis Elevator CompanyInventors: Mark S. Thompson, William A. Veronesi, John Pitts, Ary O. Mello, Hugh J. O'Donnell, John P. Wesson, William C. Perron, Douglas E.

Publication number: 20110108371Abstract: An elevator load bearing member assembly includes at least one traction enhancing surface (46) on a jacket (44). In one example, a mechanical removal process is used to strip away at least some of an amide-rich layer from the surface (46) after the jacket has been extruded onto tension members (42). In another example, a chemical removal process is used. Another disclosed example includes disrupting the surface.Type: ApplicationFiled: December 29, 2010Publication date: May 12, 2011Inventors: Mark S. Thompson, John P. Wesson, William A. Veronesi, Hugh J. O'Donnell, John Pitts, William C. Perron, Ary O. Mello, Kathryn Rauss

Patent number: 7886878Abstract: A tension member termination device optimized for terminating flexible flat tension members, the device including a socket with a compression portion and a bulbous portion and a compression plate on each side of the compression portion fastenable by fasteners extending through all of these feature. The device provides a pathway for the tension member through the device and upon torquing the fasteners reliably secures the tension member while avoiding deleterious pressure and stress therein. The invention also provides a safety clamp for optional use with the invention.Type: GrantFiled: October 10, 2003Date of Patent: February 15, 2011Assignee: Otis Elevator CompanyInventors: Richard J. Ericson, Hugh J. O'Donnell, Ary O. Mello, Dale R. Barrett, Dennis J. Rehmer
