Publication number: 20230272845Abstract: The present invention relates to a linear actuator with an improved electric motor. In particular, the invention focuses on improved technical solutions for braking or locking of a rotating electric motor by using an electro-mechanical locking mechanism. The mechanism uses a solenoid having a nonrotating locking element, which is displaceable by solenoid action and arranged to engage with a rotating locking element. In particular, solutions have been found in which a surprisingly small solenoid with a much-reduced requirement on stroke length may be deployed to effectively unidirectionally or bidirectionally lock against rotation of the motor.Type: ApplicationFiled: June 2, 2021Publication date: August 31, 2023Inventors: Ulrik Nytoft Rasmussen, Frederik Hedevang Lyngdorf, Michael Randløv, Jesper Madsen Wolf

Patent number: 11712110Abstract: Electrical operating unit comprising a first and a second part, where the two parts can be mutually adjusted. The Operating unit (1) comprises a first part constructed as a housing (2), which contains the electric equipment with at least one electric switch and a second part constructed as a mounting unit (3) for the first part. The two parts are interconnected about a shaft (17), or pivot, so they can rotate mutually. When the operating unit is mounted the housing (2) will assume a first position, an initial position. By pressing the housing (2) it rotates about the shaft (17) and is brought into a second position, an activation position, where the switch(es) is/are activated in that they are pressed against the second part (3). With this embodiment of the operating unit the piece of furniture can be adjusted in either direction by pressing the housing (2). The housing (2), besides from functioning as a switch, can also be equipped with other switches and displays.Type: GrantFiled: November 24, 2021Date of Patent: August 1, 2023Assignee: Linak A/SInventor: Jesper Madsen Wolf
