Publication number: 20070267841Abstract: A vehicle step tube comprising a one-piece elongated extrusion having a plurality of vertical ribs extending from the upper surface. The ribs are relatively short in a step portion of the extrusion to form a step platform. The ribs are relatively tall in the non-step portions flanking the step portion. The ribs define transverse recesses in the step portion to enhance traction and aesthetics.Type: ApplicationFiled: August 1, 2007Publication date: November 22, 2007Applicant: STEFFENS ENTERPRISES, INC.Inventor: Craig Mulder

Patent number: 7007765Abstract: A powered wheeled carriage includes a patient support and a wheeled base. An auxiliary wheel mechanism includes an auxiliary wheel spring support for biasing an auxiliary wheel into contact with a floor. Operating a control apparatus moves the auxiliary wheel away from the floor. A drive handle pivots about a single axis to control a drive motor that powers the auxiliary wheel. The drive handle controls driving of the wheeled carriage in forward and rearward directions. A decision/drive circuit ramps the speed of the wheeled carriage for a few second after start-up to prevent a jerking motion. A display/control panel displays the condition of the carriage brake and the condition of the auxiliary wheel to assist an operator.Type: GrantFiled: April 28, 2004Date of Patent: March 7, 2006Assignee: Stryker CorporationInventors: Keith Waters, Dennis Reed, Mark Friedman, Craig Mulder, Steve Nichols

Publication number: 20050264024Abstract: A latching and locking system for a cover for the cargo bed of a vehicle having a tailgate. The system includes a cover latch, a first manual operator for releasing the cover latch, and a second automatic operator for automatically releasing the cover latch if the tailgate is moved to its closed position when the cover is closed and locked. The system includes a single cable interconnecting the latch and the first and second operators. The second operator carries a movable tailgate latch. Finally, the system includes a single lock operatively connected to both the first operator and the tailgate latch.Type: ApplicationFiled: May 27, 2004Publication date: December 1, 2005Inventors: Craig Mulder, John Arend

Publication number: 20050263975Abstract: A vehicle step tube comprising a one-piece elongated extrusion having a plurality of vertical ribs extending from the upper surface, the ribs define a plurality of channels between the ribs. The ribs may be relatively short in a step portion of the extrusion to form a step platform, and may be relatively tall in the flanking portions flanking the step portion. The ribs may further define transverse recesses in the step portion to enhance traction and aesthetics. A pair of end caps may be provided to cover the ends of the extrusion. The ends caps include openings aligned with the channels to allow fluid flow through the channels and the openings and into an environment.Type: ApplicationFiled: November 19, 2004Publication date: December 1, 2005Inventors: Craig Mulder, Charles Steffens

Publication number: 20040200646Abstract: A power assisted wheeled carriage includes a patient support having a length, a wheeled base supporting the patient support, and an auxiliary wheel mechanism including an auxiliary wheel spring support for biasing an auxiliary wheel into contact with a floor. The carriage further includes a control apparatus for moving the auxiliary wheel away from the floor. The auxiliary wheel spring support can be a spring steel member having an opening and biased to move the auxiliary wheel into contact with the floor. The control apparatus can include a foot pedal for turning a rotatable shaft that enables a cam apparatus to apply an upward force to the auxiliary wheel. The wheeled carriage also includes a drive handle pivotable about a single axis to control a drive motor for the auxiliary wheel. The drive handle controls driving of the wheeled carriage in forward and rearward directions. Safety sensors on the drive handle require grasping thereof at a specific location to operate the carriage.Type: ApplicationFiled: April 28, 2004Publication date: October 14, 2004Applicant: Stryker CorporationInventors: Keith Waters, Dennis Reed, Mark Friedman, Craig Mulder, Steve Nichols

Patent number: 6073371Abstract: A vehicle snowplow system with an adjustable-bias tripping mechanism. The system includes a snowplow blade or moldboard which is pivotally mounted to a frame, the latter being adapted for mounting to a vehicle. The moldboard "trips" or pivotally moves between a normal plowing position and a displaced position when a lower region of the moldboard contacts a rigid obstruction. The system includes at least one biasing assembly operable to bias the moldboard toward the normal position with a biasing force, the biasing assembly configured so as to provide an adjustment to the biasing force to compensate for variances in roadway or environmental conditions.Type: GrantFiled: December 22, 1997Date of Patent: June 13, 2000Assignee: Henderson Manufacturing CompanyInventors: Mary T. Goos, Glen A. Galloway, Jeffery L. Jacobson, Janet A. Kelley, Craig A. Mulder, Terry L. Solomon, Richard A. Nachtman, Leslie L. Shaw, Jeffrey D. Johnson
