Publication number: 20190061864Abstract: A steering device for small vehicles has a transverse control arm which is situated on a height-adjustable handlebar formed form two telescopic tubes. The inner tube has at least two openings or grooves which are formed at different heights and into which a latching element mounted in the outer tube can latch into position. A height-adjustment and locking device in the form of a clamping sleeve surrounds the two tubes at their connection point and is displaceable along the inner tube in the direction of the outer tube against the force of a spring. The locking device is provided, on its inner side, with a conically tapering end portion which engages around the outer tube and, in the relaxed state of the spring, acts on an outer surface of the latching element, which protrudes radially outward through an opening in the outer tube, and presses the latching element radially inward.Type: ApplicationFiled: August 28, 2018Publication date: February 28, 2019Applicant: Brake Force One GmbHInventors: STEFAN STARK, PETER VOITL

Patent number: 9631304Abstract: A variable timing system for a sewing machine is provided comprising a shuttle hook having a hook tip, a first helical gear mounted on the shuttle hook, a lower shaft configured to rotate the shuttle hook in synchronization with a needle bar, and a second helical gear mounted on the lower shaft and capable of engaging with the first helical gear. In accordance with embodiments, at least one of the helical gears is axially movable. The variable timing system may comprise a control device configured to generate a control signal representative of a current sewing situation. A drive force mechanism may receive the control signal and in response, transmit axial movement to the axially moveable helical gear to move the gear into proper position relative to a threaded needle of the sewing machine.Type: GrantFiled: March 12, 2014Date of Patent: April 25, 2017Assignee: Singer Sourcing Limited LLCInventors: Bertil Friman, Rolf Wahlström, Kent Askenmalm, Stefan Stark

Patent number: 9260008Abstract: The invention relates to a closure device (2) for closing a refill opening of a tank such as, a fuel tank or a lubricant tank. The closure device includes a body portion (20) for engagement with the refill opening. The closure device (2) further includes a pivotal member (6) provided with a grip portion (3). The grip portion (3) may be switched between a retracted position and a protruding position. In protruding position, the grip portion (3) extends outwardly of the body portion (20) to form a convenient grip to an operator. A holding member (13, 14, 17) may be provided to hold the pivotal member (6) in the protruding position. The holding member (13, 14, 17) may be secured to the pivotal member (6) and to the body portion (20). The closure device (2) may further comprise a biasing member (11) arranged for urging the pivotal member (6) towards the retracted position.Type: GrantFiled: February 23, 2010Date of Patent: February 16, 2016Assignee: HUSQVARNA ABInventors: Pär Martinsson, Stefan Stark

Patent number: 9156183Abstract: A chainsaw may include a guide bar, a cutting chain and a driving unit arranged to drive the cutting chain around the guide bar. The guide bar defines a first longitudinal axis extending along a center of the guide bar. The chainsaw further comprising a handle section for carrying and operating the chainsaw, wherein the handle section includes a control portion disposed on the upper side of the chainsaw. The control portion in turn includes a throttle lever for controlling the speed of the driving unit and the control portion has a left and a right side. The control portion defines a second longitudinal axis substantially extending along an upper side of at least a part of the control portion. An angle, A, between the first and the second longitudinal axes is between 14° and 45°.Type: GrantFiled: November 8, 2011Date of Patent: October 13, 2015Assignee: HUSQVARNA ABInventors: Mats Andersson, Rikard Rydberg, Stefan Stark

Patent number: 9091235Abstract: An air inlet system (100) for an internal combustion engine includes an air filter (1) and a flow resistance means (2). The air filter (1) includes one or more filter elements (12), an interior chamber (3) and a suction opening (6). The suction opening (6) is provided to connect the interior chamber (3) to a suction channel (7) of an engine. During operation of the engine, the combustion air flows through the one or more filter elements (12) into the interior chamber (3) and from the interior chamber (3) into the suction channel (7). Further, the interior chamber (3), the suction opening (6) and the suction channel (7) together define a combustion air flow path. The flow resistance means (2) is provided in the combustion air flow path. During the operation of the engine, a portion of the combustion air flows through the flow resistance means (2).Type: GrantFiled: January 14, 2010Date of Patent: July 28, 2015Assignee: HUSQVARNA ABInventors: Stefan Stark, Cecilia Åkesson
