Publication number: 20240124285Abstract: A lift device includes a base, a platform, and a scissor assembly coupling the base to the platform. The scissor assembly includes a first scissor layer, a second scissor layer, and a third scissor layer each including an inner arm pivotally coupled to an outer arm. The first scissor layer has a first middle axis offset vertically from a first end axis center point. A kicker assembly couples an actuator configured to raise and lower the platform to the second scissor layer and the third scissor layer. The kicker assembly includes a kicker with opposing first and second kicker ends. The kicker is pivotally coupled to the second scissor layer and releasably coupled to the third scissor layer. The actuator rotates the kicker relative to the second scissor layer. A guide is coupled to the kicker and configured to limit the rotation of the kicker.Type: ApplicationFiled: October 17, 2022Publication date: April 18, 2024Applicant: Oshkosh CorporationInventors: Mark G. Neubauer, Benjamin C. Bruno, Devin J. Rosencrance, Patrick Dingman

Publication number: 20230286790Abstract: A lift device includes a scissor assembly coupling a base to a platform. The scissor assembly includes a first scissor layer including a first inner arm configured to rotate relative to a first outer arm about a middle axis. The first scissor layer has an end axis center point defined based on the positions of the end axes about which the first inner arm and the first outer arm rotate. The first middle axis is offset from the first end axis center point. The scissor assembly further includes a second scissor layer coupled to the first scissor layer and extending between the first scissor layer and the platform. The second scissor layer includes a second inner arm pivotally coupled to a second outer arm.Type: ApplicationFiled: May 19, 2023Publication date: September 14, 2023Applicant: Oshkosh CorporationInventors: Mark G. Neubauer, Benjamin C. Bruno, Devin J. Rosencrance

Publication number: 20230271815Abstract: A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, a scissor assembly coupling the base to the platform, and a booster. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm, a pulley coupled to the scissor layer, a tensile member wrapped around the pulley, and an actuator configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base. A booster is positioned to engage a portion of the tensile member and apply an upward force on the scissor assembly when the platform is in the fully lowered position.Type: ApplicationFiled: May 5, 2023Publication date: August 31, 2023Applicant: Oshkosh CorporationInventor: Devin J.

Patent number: 11691858Abstract: A lift device includes a base, a platform configured to support an operator, and a scissor assembly coupling the base to the platform. The scissor assembly includes a first scissor layer including a first inner arm pivotally coupled to a first outer arm. The first inner arm is configured rotate relative to the first outer arm about a first middle axis. The first scissor layer has a first end axis center point. An actuator is configured to move the platform between a fully raised position and a fully lowered position relative to the base. The first middle axis is offset vertically from the first end axis center point.Type: GrantFiled: March 6, 2020Date of Patent: July 4, 2023Assignee: Oshkosh CorporationInventors: Mark G. Neubauer, Benjamin C. Bruno, Devin J. Rosencrance

Patent number: 11679966Abstract: A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, and a scissor assembly coupling the base to the platform. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm. The first scissor arm is configured to rotate relative to the second scissor arm about a middle axis that extends laterally. A pulley is coupled to the first scissor arm. A tensile member is wrapped around the pulley and coupled to the second scissor arm. An actuator is configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base.Type: GrantFiled: March 6, 2020Date of Patent: June 20, 2023Assignee: Oshkosh CorporationInventor: Devin J.

Patent number: 11498819Abstract: A lift device includes a base, a platform configured to support an operator, and a scissor assembly coupling the base to the platform. The scissor assembly includes an actuator configured to extend and retract the scissor assembly to move the platform between a fully raised position and a fully lowered position, a first scissor arm pivotally coupled to a second scissor arm, and a prop pivotally coupled to the first scissor arm such that the prop rotates about a lateral axis. The prop is configured to selectively engage an engagement surface defined by at least one of the second scissor arm and a protrusion coupled to the second scissor arm, thereby preventing the platform from reaching the fully lowered position.Type: GrantFiled: March 6, 2020Date of Patent: November 15, 2022Assignee: Oshkosh CorporationInventors: Benjamin C. Bruno, Devin J. Rosencrance
