Abstract
Abstract A ramp is provided for use with vehicles having tailgates. The ramp is attached to the tailgate. The ramp is capable of folding into a bed of the vehicle and against the tailgate when not in use, and is folded away from the vehicle and the tailgate to extend toward the ground or other loading surface for use. A hinge controls the movement of the device relative to the tailgate of the vehicle to allow the device to be pivoted into position for use, and to be pivoted into the storage position against the tailgate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
A loading ramp for vehicles having tailgates, comprising: a. generally rectangular, planar ramp means; b. clamping means which attaches to a tailgate of a vehicle; and c. a hinge which attaches said ramp means to said clamping means, wherein said hinge is attached to said ramp means by a first pivot point which allows said ramp means to rotate about said pivot point, and said hinge is connected to said clamping means by a second pivot point which allows said hinge to rotate relative to said clamping means.
Claim 2
Dependent Claim
88 words
A loading ramp for vehicles having tailgates, comprising: a. generally rectangular, planar ramp means; b. clamping means which attaches to a tailgate of a vehicle; and c. a hinge which attaches said ramp means to said clamping means, wherein said hinge is attached to said ramp means by a first pivot point which allows said ramp means to rotate about said pivot point, and said hinge is connected to said clamping means by a second pivot point which allows said hinge to rotate relative to said clamping means.
Claim 3
Dependent Claim
206 words
A loading ramp for vehicles having tailgates, comprising: a. a first ramp section; b. a second ramp section; c. a first hinge for connecting said first ramp section and said second ramp section, wherein said first ramp section pivots about said first hinge relative to second ramp section, and a top plane of said first ramp section is pivoted to a position which is generally in the same plane as a top plane of said second ramp section, and said top plane of said first ramp section is pivoted to a position wherein a bottom surface of said first ramp section is between said top plane of said first ramp section and said top plane of said second ramp section; d. clamping means which attaches to a tailgate of a vehicle; and e. a second hinge which attaches said second ramp section to said clamping means, wherein said second hinge is attached to said second ramp section by a first pivot point which allows said first ramp section and said second ramp section to rotate about said pivot point, and said second hinge is connected to said clamping means by a second pivot point which allows said second hinge to rotate relative to said clamping means.
Claim 4
Dependent Claim
206 words
A loading ramp for vehicles having tailgates, comprising: a. a first ramp section; b. a second ramp section; c. a first hinge for connecting said first ramp section and said second ramp section, wherein said first ramp section pivots about said first hinge relative to second ramp section, and a top plane of said first ramp section is pivoted to a position which is generally in the same plane as a top plane of said second ramp section, and said top plane of said first ramp section is pivoted to a position wherein a bottom surface of said first ramp section is between said top plane of said first ramp section and said top plane of said second ramp section; d. clamping means which attaches to a tailgate of a vehicle; and e. a second hinge which attaches said second ramp section to said clamping means, wherein said second hinge is attached to said second ramp section by a first pivot point which allows said first ramp section and said second ramp section to rotate about said pivot point, and said second hinge is connected to said clamping means by a second pivot point which allows said second hinge to rotate relative to said clamping means.
Claim 5
Dependent Claim
72 words
A loading ramp for vehicles having tailgates as described in claim 2, further comprising a tailgate which is pivotally attached to a vehicle, and wherein said first ramp section and said second ramp section each have a height which is less than a corresponding height of said tailgate, and wherein said first ramp section and said second ramp section have a width which is less than a corresponding width of said tailgate.
Claim 6
Dependent Claim
51 words
A loading ramp for vehicles having tailgates as described in claim 1, wherein said clamping device comprises a clamp having generally parallel members, with one of said generally parallel members positioned on one side of a tailgate, and a remaining generally parallel member positioned on an opposite side of said tailgate.
Claim 7
Dependent Claim
51 words
A loading ramp for vehicles having tailgates as described in claim 2, wherein said clamping device comprises a clamp having generally parallel members, with one of said generally parallel members positioned on one side of a tailgate, and a remaining generally parallel member positioned on an opposite side of said tailgate.
Claim 8
Dependent Claim
51 words
A loading ramp for vehicles having tailgates as described in claim 3, wherein said clamping device comprises a clamp having generally parallel members, with one of said generally parallel members positioned on one side of said tailgate, and a remaining generally parallel member positioned on an opposite side of said tailgate.
Claim 9
Dependent Claim
197 words
A loading ramp for vehicles having tailgates, comprising: a. a first ramp section; b. a second ramp section; c. a first hinge for connecting said first ramp section and said second ramp section, wherein said first ramp section pivots about said first hinge relative to second ramp section, and a top plane of said first ramp section is pivoted to a position which is generally in the same plane as a top plane of said second ramp section, and said first ramp section and said second ramp second are pivoted to a position wherein said first ramp section, said second ramp section and a tailgate of a vehicle are in a generally parallel relationship; d. clamping means which attaches to said tailgate; and e. a second hinge which attaches said second ramp section to said clamping means, wherein said second hinge is attached to said second ramp section by a first pivot point which allows said first ramp section and said second ramp section to rotate about said pivot point, and said second hinge is connected to said clamping means by a second pivot point which allows said second hinge to rotate relative to said clamping means.
