Patent number: 7971687Abstract: An elevator load bearing assembly (20) includes a plurality of cords (22) within a jacket (24). The jacket has a plurality of grooves (32, 34, 36, 38 40) spaced along the length of the belt assembly. Each groove has a plurality of portions (50, 52, 54, 56) aligned at an oblique angle (A, B) relative to a longitudinal axis (48) of the belt (20). In one example, the grooves are separated such that there is no longitudinal overlap between adjacent grooves. In another example, transitions (60, 64) between the obliquely aligned portions are at different longitudinal positions on the belt. Another example includes a combination of the different longitudinal positions and the non-overlapping groove placement.Type: GrantFiled: February 7, 2003Date of Patent: July 5, 2011Assignees: Otis Elevator Company, ContiTech Antriebssysteme GmbHInventors: Goldino Alves, Ary Mello, Xiaodong Luo, Bill Perron, Hugh O'Donnell, Paul von Hardenberg, Mark Marler, John Pitts, Randy Roberts, Hubert E.

Patent number: 7361007Abstract: Tubular-shaped flexible members for air springs are made of rubber or rubber-like elastomers and are reinforced by reinforcement layers. In order that the air spring flexible member can roll telescopically off a roll-off piston, the tubular-shaped flexible member sections must be brought into a slightly conical or bottle-like configuration and then vulcanized in this form. A method forms and vulcanizes an air spring flexible member blank and utilizes an apparatus which includes a mold defining a bellied inner wall defining a common hollow space for receiving the air spring flexible member blank therein. A pressure bellows unit includes a pressure bellows extending axially in the common hollow space as well as first and second end pieces joined to the pressure bellows at corresponding longitudinal ends thereof.Type: GrantFiled: September 28, 2005Date of Patent: April 22, 2008Assignee: ContiTech Luftfedersysteme GmbHInventors: Christoph Bederna, Hubertus Gawinski

Patent number: 7267152Abstract: An arrangement (1) for guiding individual reinforcement filaments (2) onto a carrier (3) has a positioning disc (4) with a plurality of filament guides (9) arranged distributed on a circular ring of the positioning disc (4). The carrier is moveable in the direction of the carrier axis (X). The arrangement also includes a rotationally symmetrical deflecting element (5). The positioning disc (4) and the deflecting element (5) each concentrically surround the carrier (3). The deflecting element (5) is mounted within the positioning disc (4) and aligned axially to the positioning disc (4). The inlet-end peripherally extending inner edge (6) of the deflecting element (5) faces toward the carrier (3) and is curved. The filament guides (9) open directly at the curved inner edge (6).Type: GrantFiled: May 16, 2003Date of Patent: September 11, 2007Assignee: Contitech Luftfedersysteme GmbHInventors: Markus Berger, Rainer Oehl, Klaus Binder, Christoph Bederna

Patent number: 7001553Abstract: Tubular-shaped flexible members for air springs are made of rubber or rubber-like elastomers and are reinforced by reinforcement layers. In order that the air spring flexible member can roll telescopically off a roll-off piston, the tubular-shaped flexible member sections must be brought into a slightly conical or bottle-like configuration and then vulcanized in this form. A method forms and vulcanizes an air spring flexible member blank and utilizes an apparatus which includes a mold defining a bellied inner wall defining a common hollow space for receiving the air spring flexible member blank therein. A pressure bellows unit includes a pressure bellows extending axially in the common hollow space as well as first and second end pieces joined to the pressure bellows at corresponding longitudinal ends thereof.Type: GrantFiled: October 10, 2003Date of Patent: February 21, 2006Assignee: ContiTech Luftfedersysteme GmbHInventors: Christoph Bederna, Hubertus Gawinski

Patent number: 6868747Abstract: A linear drive includes a toothed belt (2) driven by direction-changing rollers (1) in the pretensioned state. The toothed belt (2) has at least one tension reinforcement. The teeth (3) of the belt (2) engage in the teeth gaps (4) of a linear toothed counterpiece (5) over a specific length. The pitch of the teeth (3) of the belt is slightly less, up to 0.8%, than the pitch of the toothed counterpiece (5) in the pretensioned state of the toothed belt (2) and during loading of the toothed belt which occurs during operation under load. The tooth flank (6) of the tooth (3) of the belt is at right angles or almost at right angles to the plane of the tension reinforcement (7) and the tooth gap (4) of the toothed counterpiece (5) is approximately 20% to 80% wider than the width of the tooth (3) of the belt. The belt teeth (3) are elastically configured compared to the high stiffness of the tension reinforcement (7).Type: GrantFiled: June 20, 2002Date of Patent: March 22, 2005Assignee: ConiTech Antriebssysteme GmbHInventors: Hubert Göser, Christoph Bederna
