Patent number: 11673771Abstract: According to an aspect, there is provided an elevator car parking brake comprising brake pads and an actuator configured to move the brake pads with respect to a guide rail. The elevator car parking brake further comprises levers, each having an associated brake pad; and at least one screw associated with the actuator and rotatably fixed to at least one lever via at least one attaching member. In a braking operation, the actuator is configured to rotate the at least one screw in a first direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move towards the guide rail. In a brake release operation, the actuator is configured to rotate the at least one screw in a second direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move away from the guide rail.Type: GrantFiled: December 30, 2019Date of Patent: June 13, 2023Assignee: Kone CorporationInventors: Antti Koskinen, Hilkka Hamalainen, Timo Vlasov, Mikko Puranen, Antti Saarelainen, Henri Wenlin

Patent number: 11618647Abstract: According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.Type: GrantFiled: December 30, 2019Date of Patent: April 4, 2023Assignee: Kone CorporationInventors: Antti Koskinen, Antti I Maki, Jukka Turpeinen, Hilkka Hamalainen, Antti Saarelainen, Henri Wenlin, Mikko Puranen, Timo Vlasov, Jukka Penttila, Jorma Sarkkinen

Publication number: 20230032978Abstract: An apparatus for actuating a safety gear of an elevator includes a first stage actuation mechanism; and a second stage actuation mechanism. The second stage actuation mechanism includes a wedge arrangement configured to grip a guiderail associated with the elevator when the first stage actuation mechanism is triggered; a casing including the wedge arrangement and configured for vertical linear movement along the guiderail; and a transmission member coupled to the casing from a first end and to the safety gear from a second end. The apparatus is configured to cause the safety gear to actuate when the first stage actuation mechanism is triggered, the first stage actuation mechanism causing the wedge arrangement of the second stage actuation mechanism to grip the guiderail of the elevator and to decelerate vertical movement of the casing in relation to the guiderail, the deceleration of the casing causing the transmission member to engage the safety gear to the guiderail to stop the elevator.Type: ApplicationFiled: October 14, 2022Publication date: February 2, 2023Applicant: KONE CorporationInventors: Antti Koskinen, Petri Hartikainen, Pekka Hallikainen, Antti I Mäki

Patent number: 11498803Abstract: According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.Type: GrantFiled: December 19, 2019Date of Patent: November 15, 2022Assignee: Kone CorporationInventors: Antti Koskinen, Jani Renvall

Patent number: 11459208Abstract: The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.Type: GrantFiled: November 25, 2019Date of Patent: October 4, 2022Assignee: Kone CorporationInventors: Pekka Hallikainen, Antti I Maki, Antti Koskinen, Petri Hartikainen
