Patent number: 11851845Abstract: Power machines with implement carriers that can sense the proximity of an implement to the implement carrier with a plurality of sensors. Such sensing is indicative of the likelihood of an implement being positioned adjacent to the implement carrier. In some embodiments, a sensor detects whether a locking mechanism is activated.Type: GrantFiled: November 1, 2018Date of Patent: December 26, 2023Assignee: DOOSAN BOBCAT NORTH AMERICA INC.Inventors: Cody Erhardt, Jonathan J. Roehrl

Patent number: 10711431Abstract: A clamp implement and a control system for controlling the clamp implement such that the clamp implement can be caused to follow motion of a bucket or other primary implement in a selected mode of operation. In another mode of operation, the claim implement can be caused to move independently of the primary implement.Type: GrantFiled: November 1, 2018Date of Patent: July 14, 2020Assignee: CLARK EQUIPMENT COMPANYInventors: Kevin J Zent, Jonathan J.

Patent number: 10597846Abstract: A method of controlling a lift arm actuator and a tilt actuator to control positioning of an implement carrier coupled to a lift arm of a power machine. An activation signal is received from an enabling input device. A lift arm control signal is received from a lift arm control input commanding movement of the lift arm. The lift arm actuator is controlled responsive to receipt of both of the activation signal and the lift arm control signal to move the lift arm to a target lift arm position and to move the implement carrier to or maintain the implement carrier at a target implement carrier orientation relative to a gravitational direction.Type: GrantFiled: April 20, 2018Date of Patent: March 24, 2020Assignee: Clark Equipment CompmanyInventors: Kevin J. Zent, Trevor W. Krause, Jonathan J. Roehrl, Marty Carpenter

Patent number: 10480154Abstract: Disclosed embodiments include implement carriers and power machines with implement carriers. In some embodiments, the implement carriers have a mounting structure having first and second mounting structure surfaces with first and second pluralities of mounting features located along the first mounting structure surfaces, respectively. Each of the second plurality of mounted features is aligned with one of the first plurality of mounting features. The mounting structure is configured to receive an implement in a first attitude and a second attitude different from the first attitude.Type: GrantFiled: February 22, 2013Date of Patent: November 19, 2019Assignee: Clark Equipment CompanyInventors: Jim M. Breuer, Kevin J. Zent, Jonathan J. Roehrl, Scott N. Schuh

Patent number: 10336292Abstract: Disclosed seat belt assemblies or mechanisms include a seat belt guide which positions the seat belt for convenient ingress and egress by an operator, but in a position which reminds the operator to fasten the seat belt. The seat belt guide is configured to be stiffer in one direction of movement to maintain the metal tab of the seat belt at a raised position to one side of the operator seat, for example at a position adjacent to an operator joystick or control, but to allow the guide and the seat belt to be moved across the operator seat (and operator) for buckling.Type: GrantFiled: August 29, 2017Date of Patent: July 2, 2019Assignee: Clark Equipment CompanyInventors: Brian P. Dehnert, Jonathan J. Roehrl

Patent number: 10189512Abstract: A mechanical linkage between operator input devices and actuators including a junction having a first portion operably coupled to an operator input device and a second portion operably coupled to an actuator. The first and second portions of the junction are connected when a cab is in an operating position and disconnected when a cab is in a service position. When connected, the first and second portions create a solid connection between the operator input device and the actuator. When the first and second portions are disconnected, the operator input will be not be operably coupled to the actuator. Movement of the cab to the operating position will cause the first and second portions to become connected and movement away from the operating position will cause the first and second portions to become disconnected.Type: GrantFiled: February 3, 2017Date of Patent: January 29, 2019Assignee: Clark Equipment CompanyInventors: Brian P. Dehnert, Ronald S. Hansen, Matthew J. Kaldor, Jeret L. Hoesel, Jonathan J. Roehrl
