Patent number: 11866799Abstract: A method of producing a shaped structure support, e.g., for a vehicle, is disclosed. The method includes: heating a hollow workpiece of a steel material to a material transformation temperature range; deforming the hollow workpiece in a press into the shaped structure support having a predefined complex geometry while the hollow workpiece is in the material transformation temperature range; and quenching the hollow workpiece through contact with a press tool of the press to provide the shaped structure support with a martensitic microstructure.Type: GrantFiled: April 23, 2021Date of Patent: January 9, 2024Assignee: L & W EngineeringInventors: Dean Richardson, Jason Bigelow

Patent number: 10040108Abstract: A support may include a hollow metallic tube extending over an axis and may include two opposing ends. The tube may include a plurality of sections disposed along the axis. A first section may be disposed at an end of the tube and include a first inner diameter, a first outer diameter, and a first wall thickness. A second section may be separated from the first section via a first transition zone. The second section may include a second inner diameter, a second outer diameter, and a second wall thickness. A third section may be disposed remote from the first section and be separated from the second section via a second transition zone. The third section may have a third inner diameter, a third outer diameter, and a third wall thickness. The wall thickness, inner diameter and outer diameter may vary along the tube between the plurality of sections.Type: GrantFiled: August 27, 2015Date of Patent: August 7, 2018Assignee: L&W EngineeringInventor: Jim Wines

Patent number: 9546746Abstract: A support structure may include a metallic tube having two opposing ends. The first end may have a first length, a first wall thickness, and a first outer diameter. The second end may have a second length, a second wall thickness, and a second outer diameter. A transition area may be disposed between the first length and the second length. The first wall thickness may be greater than the second wall thickness thereby providing variable thickness.Type: GrantFiled: January 6, 2014Date of Patent: January 17, 2017Assignee: L & W ENGINEERINGInventors: Scott Jones, Joshua Forquer

Patent number: 7407221Abstract: A support structure for components within a vehicle is provided. The support structure includes a beam comprising a hollow metal tube coupled to vehicle's body. The tube is constructed of a single piece of tubing having first and second portions. The first portion has a first diameter and a first thickness, the second portion has a second diameter and a second thickness. The second diameter is larger than the first diameter and the second thickness is greater than the first thickness.Type: GrantFiled: November 24, 2004Date of Patent: August 5, 2008Assignee: L&W Engineering IncorporatedInventors: James Kring, Gene Goins, Dean Richardson

Patent number: 6837518Abstract: An energy absorbing knee bolster for use in an interior of a vehicle is disclosed. The knee bolster is configured to absorb energy from the vehicle's occupants during a crash. The knee bolster is formed of a collapsible cylinder which is welded to an impact plate on its first end and to a vehicle's cross-car beam at its second end. A coupling flange is disposed between the impact plate and a medial portion of the collapsible cylinder. The collapsible cylinder is configured to axially collapse at a predetermined force when impacted by a moving occupant.Type: GrantFiled: August 23, 2002Date of Patent: January 4, 2005Assignee: L&W Engineering IncorporatedInventor: Brian J. Mullan

Patent number: 5549319Abstract: A toe-in angle adjustment mechanism is provided which comprises a geared adjustment plate that is attached to a suspension arm for a rear wheel. The adjustment plate has a bushing centrally mounted therein and is connected to the wheel spindle. A locking plate is provided to prevent unwanted frame movement of the wheel angle during adjustment. The locking plate has an access for a geared adjustment tool for engaging the teeth of the adjustment plate to pivot the adjustment plate and thus the spindle to adjust the toe-in angle of the wheel.Type: GrantFiled: August 24, 1994Date of Patent: August 27, 1996Assignee: L & W Engineering CompanyInventor: James T.
