Abstract
A lift gate for loading and unloading cargo from a vehicle. The lift gate includes a moveable load platform and a ramp. The ramp is coupled to the load platform such that the ramp rotates between various positions at the selection of a user.
Claims17
A lift gate arranged to be attached to a vehicle for use in loading and unloading cargo from the vehicle, the lift gate comprising:
- a lift mechanism arranged to be coupled to the vehicle, and
- a load platform coupled to the lift mechanism and moveable between a lowered position and a raised position at the selection of a user, the load platform comprising:
- a deck section including a proximal end coupled to the lift mechanism and a distal end spaced apart from the proximal end,
- an end ramp coupled to the distal end of the deck section and configured to rotate relative to the deck section between a closed position where the end ramp is positioned to lie along the deck section, a retention position where the end ramp is in a generally upright position, and an operational position where the end ramp extends away from the distal end of the deck section, and
- a ramp positioner coupled between the end ramp and the deck section and configured to allow the end ramp to move between the closed position, the retention position, and the operational position at the selection of a user,
- wherein the end ramp includes a proximal end and a distal end spaced apart from the proximal end, the ramp positioner includes a pair of plates coupled to the distal end of the deck section on opposing sides of the end ramp and at least one pin coupled to the end ramp between the proximal end and distal end, the pair of plates are each formed to include a slot positioned to receive the at least one pin, the at least one pin slides within the slots of the plates when moving the end ramp between the closed position, the retention position, and the operational position, and the portion of the end ramp between the pin and the proximal end defines a tab to engage the deck section and limit rotation of the end ramp relative to the deck section at the selection of a user when the end ramp is in the retention position.
