Patent number: 12065113Abstract: A toothed holding brake for a vehicle door has a shaft, an armature plate, a magnet device and a detection device. The armature plate has a first and second main surfaces arranged opposite one another, wherein an armature-plate toothed rim having a plurality of armature teeth is arranged on the second main surface. The armature plate is arranged in a locking position such that the armature teeth mesh in the carry-along teeth to prevent rotation of the shaft in at least one direction, and is arranged in a release position such that the armature teeth are arranged at a distance from the carry-along teeth to enable rotation of the shaft in both directions. The magnet device has a magnet main surface arranged facing the armature plate, wherein the magnet device is designed to move the armature plate between the locking position and the release position.Type: GrantFiled: August 14, 2019Date of Patent: August 20, 2024Assignee: KNORR-BREMSE GESELLSCHAFT MIT BESCHRÄNKTER HAFTUNGInventors: Thomas Hirtenlehner, Peter Jetzinger

Patent number: 11834886Abstract: A device for protection against entrapment for a door for a vehicle includes an extruded profile extruded from an elastomer material, wherein the extruded profile includes a door leaf wall, which faces a contact edge of a door leaf of a door when the device is mounted on the door, a sealing wall arranged in an opposing position relative to the door leaf wall and a plunger for transferring a compression force into the extruded profile. The plunger is mounted on the sealing wall and extends along a transverse axis of the extruded profile away from the door leaf wall. The device also includes at least one switching element for detecting a compression of the extruded profile, wherein the at least one switching element is arranged in the region of the plunger between the door leaf wall and the plunger.Type: GrantFiled: September 18, 2018Date of Patent: December 5, 2023Inventors: Thomas Hirtenlehner, Peter Jetzinger, Helmut Schaffer

Patent number: 9963923Abstract: A door leaf for a vehicle, in particular a rail vehicle, wherein the door leaf has a door leaf frame, a first skin mounted on a first main surface of the door leaf frame, and a second skin mounted on a second main surface opposite the first main surface. The door leaf has a heat path from the first skin to the second skin through at least two different materials, wherein the at least two different materials have a different thermal conductivity, wherein a first material of the at least two different materials has a poorer thermal conductivity than metal, in particular a poorer thermal conductivity than aluminum.Type: GrantFiled: August 9, 2013Date of Patent: May 8, 2018Assignee: KNORR-BREMSE GESELLSCHAFT MIT BESCHRÄNKTER HAFTUNGInventors: Peter Jetzinger, Thomas Witzelnig, Gerald Hölzl

Patent number: 9340216Abstract: A door leaf for a vehicle, in particular for a rail vehicle. The door leaf includes a door leaf frame for supporting a first shell, which is or can be arranged on a first main surface of the door leaf frame, and a second shell, which is or can be arranged on a second main surface of the door leaf frame opposite the first main surface. The door leaf has at least one connecting piece for thermally decoupling the first shell from the second shell, the connecting piece is or can be arranged or arrangeable on the door leaf frame. The at least one connecting piece is or can be arranged on the door leaf frame so the first shell and the second shell are movable relative to each other in at least one section of movement as a result of temperature variations.Type: GrantFiled: January 30, 2014Date of Patent: May 17, 2016Assignee: KNORR-BREMSE GESELLSCHAFT MIT BESCHRANKTER HAFTUNGInventors: Peter Jetzinger, Thomas Witzelnig, Andreas Mair

Patent number: 8517433Abstract: The invention relates to a locking device for sliding doors, or for swinging-sliding doors of vehicles, particularly of rail vehicles, by which a locking pin connected to a door leaf is fixed in the closed position thereof. The device is characterized in that in the closed position of the locking pin the same is fixed in this position by a latch, a guide bar connected to the latch and having a notch assumes a position in which a locking element of a locking lever projects into the notch, thus fixing the position of the guide bar and the locking lever in turn is held in the closed position by a toggle lever mechanism that is located in the beyond dead point position.Type: GrantFiled: December 19, 2008Date of Patent: August 27, 2013Assignee: Knoor-Bremse GmbHInventors: Christian Pritz, Peter Jetzinger, Reinhold Jarolim

Publication number: 20110209306Abstract: The invention relates to the suspension of a door leaf of a sliding door in rail-bound, mass transportation vehicles, such as underground railways, passenger train cars, means of local public transportation, and the like. The suspension mechanism includes carrying rollers in a carrying rail arranged in the upper region of the door leaf or above the door leaf. The invention includes a steel insert having an at least substantially circular track inserted into the carrying rail; the carrying rollers are designed as steel rollers having a concave cross-sectional shape on the running surface, and an adjustment roller is provided, which abuts the adjustment surface of the carrying rail opposite of the steel insert under preload.Type: ApplicationFiled: October 30, 2009Publication date: September 1, 2011Applicant: KNORR-BREMSE GMBHInventors: Christian Pritz, Peter Jetzinger
