Patent number: 10781898Abstract: A motorized positioning apparatus for a seating unit includes a motor assembly that is configured to move a linkage assembly though a series of positions that arrange the seating unit in a closed position, open position, or extended position. The motor assembly attaches directly to a footrest drive link by way of a mounting tube. In addition, the motor assembly may attach either to a base rail of the seating unit or to a rear pivot link by way of a rear mounting tube.Type: GrantFiled: December 7, 2017Date of Patent: September 22, 2020Assignee: L&P PROPERTY MANAGEMENT COMPANYInventors: Gregory Lawson, Michael Crum

Patent number: 10571038Abstract: A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.Type: GrantFiled: July 17, 2018Date of Patent: February 25, 2020Assignees: OPW Engineered Systems, Inc., Operations Technology Development, NFPInventors: Joseph P Roth, Michael Crum, Dennis R. Jarnecke, Krzysztof Wejdman, Narendar Venkatachalapathy

Patent number: 10299597Abstract: A mechanism is provided for a seating unit that moves the seating unit between closed, TV, and fully reclined positions. The mechanism allows positively holds a footrest in a closed position, preventing the footrest from sagging over time. The mechanism includes a linkage that forces a link connected to the footrest to move initially upwards as the footrest moves from a closed position to an extended position. The weight of the mechanism holds the footrest positively closed, until a force is exerted that is great enough to move past the point where the link on connected to the footrest can descend.Type: GrantFiled: February 13, 2018Date of Patent: May 28, 2019Assignee: L&P PROPERTY MANAGEMENT COMPANYInventor: Michael Crum

Publication number: 20180094711Abstract: A motorized positioning apparatus for a seating unit includes a motor assembly that is configured to move a linkage assembly though a series of positions that arrange the seating unit in a closed position, open position, or extended position. The motor assembly attaches directly to a footrest drive link by way of a mounting tube. In addition, the motor assembly may attach either to a base rail of the seating unit or to a rear pivot link by way of a rear mounting tube.Type: ApplicationFiled: December 7, 2017Publication date: April 5, 2018Inventors: Gregory Lawson, Michael Crum

Patent number: 9581276Abstract: A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.Type: GrantFiled: June 19, 2013Date of Patent: February 28, 2017Assignee: OPW-ENGINEERED SYSTEMS, INC.Inventors: Michael Crum, Krzysztof Wejdman

Patent number: 8696054Abstract: Provided is a linkage mechanism for a recliner that includes a seat rail, an arm mounting plate that is vertically supported by one or more legs, a footrest assembly adapted to extend ottoman(s) when the recliner is adjusted from a closed to an extended position, and a roller link that translates forward when the recliner is adjusted from the extended position to a reclined position. The arm mounting plate includes a forward guide slot and a rearward guide slot having respective tracks installed thereto. The roller link includes a forward roller and a rearward roller that are rotatably coupled thereto. Further, the forward and rearward rollers are moveably engaged to the tracks of the forward and rearward guide slots, respectively, facilitating the forward translation of the roller link. A pair of substantially parallel-spaced TV links act in cooperation to pivotably couple the roller link to the arm mounting plate.Type: GrantFiled: November 14, 2011Date of Patent: April 15, 2014Assignee: L & P Property Management CompanyInventor: Michael Crum
