Patent number: 9944475Abstract: A dock leveler for an edge of a loading dock which includes a frame, a two-piece lip, a lift assist spring and an assist bar. The lift assist spring is connected on a first end to the bottom side of the lip at the pivot point and connected on a second end to the frame. The assist bar is used to move the lip between the extended/engaged and retracted/disengaged positions. By attaching the lip assist spring to the bottom of the distal lip portion, the force exerted on the lip causes it to maintain closure at the pivot point between the distal and proximal lip portions when in the extended/engaged position. Additionally, the distance between the lift assist spring and lip is minimized thereby dampening a fall distance when the lip becomes unsupported by a truck trailer; and the amount of force needed to actuate the assist bar is minimized.Type: GrantFiled: March 6, 2017Date of Patent: April 17, 2018Assignee: Leum Engineering, Inc.Inventors: Grant Leum, Eric Demerath

Patent number: 9938094Abstract: A dock leveler for an edge of a loading dock which includes a frame, a two-piece lip, a lift assist spring, an assist bar and an integral safety barrier. The lift assist spring is connected on a first end to the bottom side of the lip at the pivot point and connected on a second end to the frame. The assist bar is used to move the lip between the extended/engaged and retracted/disengaged positions. The dock leveler includes a bracket with a vertical portion and a horizontal portion, the horizontal portion is secured to the frame on a frame-end and secured to the vertical portion on free-end. The lip can rotate above and over the bracket when in an extended/engaged position; the lip contacts the horizontal portion when in the retracted/disengaged position acting as a safety barrier.Type: GrantFiled: April 13, 2017Date of Patent: April 10, 2018Assignee: Leum Engineering, Inc.Inventors: Grant Leum, Eric Demerath
