Patent number: 9828213Abstract: In an elevator installation an elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. An elevator braking device includes a brake element, a force store, which is constructed to press the brake element against the brake surface, and an actuator, which can act on the brake element. A method of operating the braking device includes the actuator pressing, in a first operational setting, the brake element against the force of the force store away from the brake surface or to hold it at a spacing therefrom, and the actuator freeing, in a second operational setting, the brake element and allowing the force store to press the brake element against the brake surface.Type: GrantFiled: July 24, 2015Date of Patent: November 28, 2017Assignee: INVENTIO AGInventors: Daniel Meierhans, Faruk Osmanbasic, Marcus Junig, Michael Geisshüsler, Nicolas Gremaud, Josef A.

Patent number: 9457989Abstract: An elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. The elevator braking device has a brake housing and a force store. The brake housing is mounted to be displaceable between a first position and a second position. The force store acts on the brake housing and pushes the brake housing in the direction of a second position. In addition, the elevator braking device includes an actuator which can act on the brake housing and keep the brake housing in a first position. The actuator in its first setting can hold the brake housing in the first position against the force of the force store. In a second setting the actuator enables pushing of the brake housing into the second position. A brake element is thereby brought into contact with the brake rail.Type: GrantFiled: September 24, 2012Date of Patent: October 4, 2016Assignee: Inventio AGInventors: Daniel Meierhans, Faruk Osmanbasic, Marcus Junig, Michael Geisshusler, Nicolas Gremaud, Josef A.

Patent number: 8157060Abstract: An elevator installation has an elevator car that moves in a vertical direction along guide tracks and is braked or held at standstill by a braking equipment. The braking equipment includes at least two brake units, at least one of the brake units, but preferably each of the brake units, is provided with a wear-compensating device which, when the brake unit is opened or released, sets a clearance distance between a brake lining and an associated brake surface, which clearance arises on opening of the brake unit, in correspondence with a substantially constant value. Thereby, use may be made of customary and thus economic brake materials which may wear during braking.Type: GrantFiled: May 29, 2007Date of Patent: April 17, 2012Assignee: Inventio AGInventors: Nicolas Gremaud, Hans Kocher, Josef A. Muff

Patent number: 8020671Abstract: An elevator installation includes a guide rail and brake equipment for guiding, holding and braking the elevator installation. The brake equipment has a brake lining which co-operates with a brake surface, advantageously with the brake surface of the guide rail, for the purpose of the braking and holding. The brake surface has at least one longitudinal wedge groove or wedge elevation which is oriented in the braking direction and on which the brake lining acts in case of need. An amplification of the braking force is achieved by the longitudinal wedge groove or wedge elevation.Type: GrantFiled: November 28, 2007Date of Patent: September 20, 2011Assignee: Inventio AGInventors: Hans Kocher, Josef A. Muff

Patent number: 7232012Abstract: An elevator shaft door having a door panel composed of a front wall and rear wall, which walls are connected together by a thermally releasable material, wherein at least a part of the closing edge of the respective door panels consists of a profile member that is formed by the back wall or thermally non-detachably fastened to the back wall. In the case of a fire, the back wall separates from the front wall through release of the thermally releasable material, wherein the front wall curves by heat effect while the back wall with the closing edge retains the original shape.Type: GrantFiled: December 30, 2003Date of Patent: June 19, 2007Assignee: Inventio AGInventors: Josef A.

Patent number: 6758310Abstract: A safety brake for the load receiving portion of an elevator includes a fixing device that is displaceable relative to the load receiving portion in the direction of the guide rail between two abutments fastened to the load receiving portion. The unlocking of the safety brake after a braking process is achieved by moving the load receiving portion with the assistance of the elevator drive unit oppositely to the direction of movement before the braking process, so that one of the abutments fastened to the load receiving portion strikes the fixing device to unlock it from the guide rail.Type: GrantFiled: November 21, 2001Date of Patent: July 6, 2004Assignee: Inventio AGInventors: Josef A.
