| 1996 | Invention patented by James C. Alexander on October 21th, 1996. Abstract: A dock leveler having a frame, a deck hingedly mounted at on end to the frame and a lip hingedly mounted to the deck at another thereof. The lip has a hinge tube affixed to the lip and a gusset joined to both the lip and the hinge tube. The gusset has an end joining the lip having a width greater than an end joining the hinge tube. The gusset may have a trapezoidal shape and the end of the gusset joining the lip is affixed by two welds each spanning the width of the end joining the hinge tube and disposed between the gusset and the hinge tube. The two welds are joined to each other by extending around edges of the gusset. A single gusset may span the lip and be joined to multiple hinge tubes. |
| 2000 | Invention patented by James C. Alexander on August 13th, 2000. Abstract: A lip assembly for a dock leveler comprises a substantially flat plate forming a lip, and an integral hinge extending for substantially the width of the lip. The integral hinge in a first embodiment is formed by shaping a plate into an arcuate configuration. The integral hinge has a series of slots to engage the hinge lugs and the hinge is welded to said lip along two edges thereof. In a second preferred embodiment the lip assembly for a dock leveler comprises a substantially flat plate forming a lip, a series of hinge lugs attached to on surface of the plate in a spaced arrangement, and an integral gusset extends for substantially the width of the lip. The integral gusset is coupled to each hinge lug and is welded to the lip along a continuous edge thereof. |
