Abstract

Abstract A combination tailgate and ramp assembly 10 formed of a pair of ramps 14 and 20, which when fastened together with fastener brackets 32 and 72 form a conventional tailgate hinged and rotatable about a transverse sliderail 30. Swing pin hinge 68 supports the lower left corner of ramp 14 and swing pin hinge 70 supports the lower right hand corner of right ramp 22 and provides three dimensional rotational ability. When unfastened, ramps 14 and 22 can be rotated down, out and over to form a loading ramp.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 340 words
A combination tailgate and ramp assembly for use with a vehicle having a truck bed, side walls, a longitudinal axis and a transverse axis, which comprises: a slide rail for serving as a pivot axis for movement of the tailgate assembly from a substantially vertical position to a substantially horizontal position attached to the end of the truck bed parallel to the transverse axis; a first ramp and a second ramp, each having a longitudinal axis, and each adapted for attachment, at one corner to a first and second swing pin hinge, respectively, and each further configured in size and shape to serve, in a orientation with its longitudinal axis parallel to the transverse axis of the truck bed, as a tailgate closure panel; said first swing pin hinge for rotatable attachment to said first ramp at a corner of said ramp, said first swing pin hinge configured for rotation about the axis of the slide rail, for transverse displacement along the slide rail, for angular rotation of the first ramp from a transverse orientation of its longitudinal axis to an orientation parallel to the longitudinal axis of the truck bed, and for axial rotation of the first ramp panel normal to the axis of the slide rail; said second swing pin hinge for rotatable attachment to said second ramp at a corner of said ramp, said second swing pin hinge configured for rotation about the axis of the slide rail, for angular rotation of the second ramp from a transverse orientation of its longitudinal axis to an orientation parallel to the longitudinal axis of the truck bed, and for axial rotation of the second ramp panel normal to the axis of the slide rail; means for rotatably and slidably attaching the first swing pin hinge to the slide rail; means for rotatably attaching the second swing pin hinge to the slide rail; means for rotatably attaching the first swing pin hinge to the first ramp; and means for rotatably attaching the second swing pin hinge to the second ramp.
Claim 2
Dependent Claim 340 words
A combination tailgate and ramp assembly for use with a vehicle having a truck bed, side walls, a longitudinal axis and a transverse axis, which comprises: a slide rail for serving as a pivot axis for movement of the tailgate assembly from a substantially vertical position to a substantially horizontal position attached to the end of the truck bed parallel to the transverse axis; a first ramp and a second ramp, each having a longitudinal axis, and each adapted for attachment, at one corner to a first and second swing pin hinge, respectively, and each further configured in size and shape to serve, in a orientation with its longitudinal axis parallel to the transverse axis of the truck bed, as a tailgate closure panel; said first swing pin hinge for rotatable attachment to said first ramp at a corner of said ramp, said first swing pin hinge configured for rotation about the axis of the slide rail, for transverse displacement along the slide rail, for angular rotation of the first ramp from a transverse orientation of its longitudinal axis to an orientation parallel to the longitudinal axis of the truck bed, and for axial rotation of the first ramp panel normal to the axis of the slide rail; said second swing pin hinge for rotatable attachment to said second ramp at a corner of said ramp, said second swing pin hinge configured for rotation about the axis of the slide rail, for angular rotation of the second ramp from a transverse orientation of its longitudinal axis to an orientation parallel to the longitudinal axis of the truck bed, and for axial rotation of the second ramp panel normal to the axis of the slide rail; means for rotatably and slidably attaching the first swing pin hinge to the slide rail; means for rotatably attaching the second swing pin hinge to the slide rail; means for rotatably attaching the first swing pin hinge to the first ramp; and means for rotatably attaching the second swing pin hinge to the second ramp.
Claim 3
Dependent Claim 46 words
