Patent number: 11897731Abstract: A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.Type: GrantFiled: December 11, 2020Date of Patent: February 13, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Heinz Widmer, Volker Zapf

Patent number: 11891274Abstract: A method and a catching device are used to catch a traveling body in an elevator system wherein traveling body is movable along a rail. The catching device includes a first braking element, a second braking element, a first guide element, a second guide element and an actuating element. The first braking element and the second braking element are brought into contact with the rail for braking. A first linear bearing is formed between the first braking element and the first guide element and a second linear bearing is formed between the second braking element and the second guide element. Both guide elements are moved between a rest position and a braking initial position, the actuating element moving the two guide elements from the rest position into the braking initial position.Type: GrantFiled: November 20, 2020Date of Patent: February 6, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Astrid Sonnenmoser, Faruk Osmanbasic, Adrian Steiner, Christian Studer, Julian Stähli, Volker Zapf, Urs Camenzind

Patent number: 11891275Abstract: A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.Type: GrantFiled: December 1, 2020Date of Patent: February 6, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Heinz Widmer, Volker Zapf

Patent number: 11884514Abstract: A method and device for safety braking an elevator having an upright guide rail wherein the device includes a housing having braking elements on both sides of and being movable along the guide rail, a safety restraint on both sides between the housing and the braking elements, and a clampable and lockable actuating device that unlocks and unclamps in response to a triggering event and brings the braking elements into braking engagement with the guide rail. The actuating device, when unclamped, develops a feed force and movement transverse to the guide rail longitudinal axis engaging the braking elements with the guide rail from a laterally distanced initial position, wherein the braking elements are entrained by frictional contact on the guide rail and enter the safety restraint, and wherein the actuating device is moved back into the initial position, clamped and locked by the braking elements located in the safety restraint.Type: GrantFiled: March 13, 2020Date of Patent: January 30, 2024Assignee: INVENTIO AGInventors: Hans Blochle, Adrian Steiner, Daniel Meierhans, Julian Stahli

Patent number: 11840425Abstract: A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.Type: GrantFiled: December 11, 2020Date of Patent: December 12, 2023Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Volker Zapf

Patent number: 11807496Abstract: A catching device for a traveling body in an elevator system and a method for unblocking the catching device include at least two retaining units that can be brought into a blocked state and into an unblocked state, the retaining units retaining the traveling body on a rail in the blocked state. The retaining units are connected to the traveling body such that each of the retaining units and the traveling body can be slid relative to each other within a limited sliding displacement. A first sliding displacement of a first of the retaining units is longer than a second sliding displacement of a second of the retaining units.Type: GrantFiled: December 6, 2018Date of Patent: November 7, 2023Assignee: INVENTIO AGInventors: Adrian Steiner, Christoph Schuler, Daniel Meierhans, Julian Stähli, Philipp Müller

Publication number: 20230049908Abstract: An apparatus for guiding and braking an elevator system traveling body movable along a guide track includes a holder fastened to the body, a guide device and a braking device. The holder transmits guiding forces between the guide device, guided on at least one track surface in the longitudinal direction, and the body. The guide device is held on and is elastically movable relative to the holder transverse to the longitudinal direction by at least a predetermined tolerance distance. The braking device includes a carrier and a braking element movable between a deactivated configuration, in which a braking surface of the braking element is laterally spaced apart from the guide track, and an activated configuration, in which the braking surface abuts the guide track, in a reversible manner by an activation distance transverse to the guide track. The carrier of the braking device is rigidly coupled to the guide device.Type: ApplicationFiled: December 2, 2020Publication date: February 16, 2023Inventors: MICHAEL GEISSHÜSLER, FARUK OSMANBASIC, ADRIAN STEINER, JULIAN STÄHLI, VOLKER ZAPF

Patent number: 9273739Abstract: A brake system of an elevator, an escalator or a moving walkway includes a brake device with at least one brake shoe. The brake shoe has an effective surface which during brake use is pressed against a friction surface, which is moving or movable relative to the effective surface, of a counter-member. The brake system also includes a feed device which is supplied by a fluid source. A fluid can be fed between the effective surface of the brake shoe and the friction surface, which faces it, by means of the feed device. The friction between the effective surface and the friction surface can be influenced by the feed of the fluid.Type: GrantFiled: February 15, 2013Date of Patent: March 1, 2016Assignee: Inventio AGInventors: Daniel Meierhans, Faruk Osmanbasic, Julian Stahli, Kurt Infanger, Roland Rothenfluh
