Patent number: 11661324Abstract: A materials handling vehicle comprises an operator compartment, a compartment tower, a multi-field scanning tool, and mechanisms that facilitate movement along a travel plane in a warehouse. The tool establishes a scan field, and, within scan field bounds, an occupancy detection field and an obstacle detection field. Tool scanning hardware is configured to generate the scan field from a point of origin that is elevated relative to the operator compartment and to expand the scan field such that it intersects the operator compartment and extends laterally beyond lateral edges of the operator compartment such that the occupancy detection field falls within the operator compartment, the obstacle detection field falls outside of the operator compartment, and the multi-field scanning tool is configured to indicate the presence of an occupant in the occupancy detection field and obstacles in the obstacle detection field.Type: GrantFiled: May 31, 2022Date of Patent: May 30, 2023Assignee: Crown Equipment CorporationInventors: Franz Pöschl, Timothy A. Wellman, Stefan Hanneman, Martin Okroy, Stefan Sauer, Jess Donnely

Patent number: 11565923Abstract: A materials handling vehicle includes a mast, a load handling structure supported on the mast, one or more operator controls, and a lifting structure having a chain structure for performing a lifting and lowering of the load handling structure. The materials handling vehicle further includes a height sensor for generating a height signal corresponding to vertical movement of the load handling structure relative to the mast, and a vehicle control module for processing the height signal received from the height sensor and an operator control signal received from the one or more operator controls. The vehicle control module evaluates the height signal and the operator control signal and disables one or more vehicle functions if the height signal does not correspond to the operator control signal.Type: GrantFiled: February 19, 2019Date of Patent: January 31, 2023Assignee: Crown Equipment CorporationInventors: Martin Okroy, Masoud Karimi

Patent number: 10647559Abstract: A materials handling vehicle is provided comprising a pair of forks to be inserted in a longitudinal direction of the forks into a pallet having one or more stringers. A pallet clamp device is provided including first and second operating devices, one mounted in each fork for actuating respective punch members into engagement with an adjacent surface on the pallet. Each operating device comprises a module located within a cavity in one of the forks, the module including an actuator, one of the respective punch members, and a linkage structure connecting the actuator and the respective punch member.Type: GrantFiled: May 24, 2018Date of Patent: May 12, 2020Assignee: Crown Equipment CorporationInventors: Sebastian Schwarz, Martin Okroy

Patent number: 9926178Abstract: An actuator includes a ram structure slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. A fluid passageway structure in the ram structure defines a path for fluid to flow through the ram structure and includes an outlet in a sidewall of the ram structure. A cushioning seal located between the ram structure and the cylinder structure can engage the ram structure and a cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward an open end of the cylinder structure. The cushioning seal can move during ram structure retraction in a direction of ram structure retraction such that fluid flowing out of the ram structure sidewall outlet, when the outlet is in the gap first portion, flows between the seal and the cylinder cap.Type: GrantFiled: August 20, 2014Date of Patent: March 27, 2018Assignee: Crown Equipment CorporationInventors: Martin Okroy, Jason Kremer, Lee Wente, Kevin A.

Publication number: 20160052759Abstract: An actuator may comprise: cylinder structure, ram structure and a cushioning seal. The cylinder structure may comprise a cylinder tube, a cylinder base and a cylinder cap. The ram structure is slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. The ram structure may comprise fluid passageway structure for defining a path for fluid to move internally through the ram structure. The path may communicate with an outlet in a sidewall of the ram structure. The cushioning seal may be located between the ram structure and the cylinder structure and engage the ram structure and the cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward the cylinder structure outer open end.Type: ApplicationFiled: August 20, 2014Publication date: February 25, 2016Inventors: Martin Okroy, Jason Kremer, Lee Wente, Kevin A.
