Abstract
Abstract A vehicle tail gate ramp including a tail gate frame movably attached to a vehicle for receiving at least two air-permeable, foldable ramps. Each ramp preferably includes first and second rectangular frame members pivotally connected to each other by a hinge. When folded, the ends of each first rectangular frame member are received by the tail gate frame to be used as a tail gate. When unfolded, the free end of each second rectangular frame member attaches to the tail gate frame and the free end of each first rectangular frame member abuts the ground to form a spaced-apart pair of loading and unloading ramps.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
255 words
A vehicle tail gate ramp assembly, comprising: (a) a first tail gate member having a pivoting base and two side extensions extending therefrom attached to the vehicle for movement between a substantially vertical and a substantially horizontal position; (b) separate second and separate third air-permeable, relatively rigid members of equal length adapted to be removably received by the first member; wherein each second and third member includes (i) a first element having a first end and a second end, and (ii) a second element having a first end and a second end, wherein the second end of the second element is pivotally connected to the first end of the first element by first hinge means between a first position substantially coplanar with the first element and a second position at an angle to the first element, wherein, when each second element is in the first position and the first member is in the substantially vertical position, the first end of each second element can be received by the base of the first, movable member, with the second and third members substantially parallel and in spaced relation to form ramp means extending from the vehicle, and, wherein, when each second element is in the second position and the first member is in the substantially vertical position, the first and second ends of each respective first element can be removably received by the side extensions of the first, movable member so that the first, second and third members form a substantially air-permeable tail gate for the vehicle.
Claim 2
Dependent Claim
255 words
A vehicle tail gate ramp assembly, comprising: (a) a first tail gate member having a pivoting base and two side extensions extending therefrom attached to the vehicle for movement between a substantially vertical and a substantially horizontal position; (b) separate second and separate third air-permeable, relatively rigid members of equal length adapted to be removably received by the first member; wherein each second and third member includes (i) a first element having a first end and a second end, and (ii) a second element having a first end and a second end, wherein the second end of the second element is pivotally connected to the first end of the first element by first hinge means between a first position substantially coplanar with the first element and a second position at an angle to the first element, wherein, when each second element is in the first position and the first member is in the substantially vertical position, the first end of each second element can be received by the base of the first, movable member, with the second and third members substantially parallel and in spaced relation to form ramp means extending from the vehicle, and, wherein, when each second element is in the second position and the first member is in the substantially vertical position, the first and second ends of each respective first element can be removably received by the side extensions of the first, movable member so that the first, second and third members form a substantially air-permeable tail gate for the vehicle.
Claim 3
Dependent Claim
41 words
The assembly as recited in claim 1, wherein at least one of the first and second elements comprises: a metal rectangular frame having metal mesh attached thereto and reinforcing means extending substantially from the first end to the second end thereof.
Claim 4
Dependent Claim
43 words
The assembly as recited in claim 2, wherein the first end of each second element comprises: a rigid lip member capable of being received in hooking relation by the base of the first member when the second elements are in the first position.
Claim 5
Dependent Claim
188 words
The assembly as recited in claim 3, wherein each second and third member further comprises: a third element having a first end and a second end, the first end thereof being pivotally connected to the second end of the first element by a second hinge means between a first position substantially coplanar with the first element and a second position at an angle to the first element, wherein, when the second and third elements are in the first position and the first member is in the substantially vertical position, the first end of each second element can be received by the base of the first member, with the second and third members substantially parallel and in spaced relation to form ramp means extending from the vehicle and, wherein, when the second and third elements are in the second position and the first member is in the substantially vertical position, the first and second ends of each respective first element can be received by the side extensions of the first, movable member so that the first, second and third members form a substantially airpermeable tail gate for the vehicle.
Claim 6
Dependent Claim
36 words
The assembly as recited in claim 4, wherein the third element comprises: a metal rectangular frame having metal mesh attached thereto and reinforcing means extending substantially from the first end thereof to the second end thereof.
Claim 7
Dependent Claim
52 words
The assembly as recited in claim 5, wherein the first and second hinge means comprise: (i) a plurality of colinear holes formed in each of the ends of the first, second and third elements connected by the hinge means, and (ii) a rod extending through each of the plurality of colinear holes.
Claim 8
Dependent Claim
211 words
The assembly recited in claim 1, further comprising: a separate fourth, air-permeable, relatively rigid member also adapted to be removably received by the first member, including (i) a first element having a first end and a second end, and (ii) a second element having a first end and a second end, wherein the second end of the second element is pivotally connected to the first end of the first element by first hinge means between a first position substantially coplanar with the first element and a second position at an angle to the first element, wherein, when each second element is in the first position and the first member is in the substantially vertical position, the first end of each second element can be received by the base of the first, movable member, with the second and third members substantially parallel and in spaced relation to form ramp means extending from the vehicle, and wherein, when the second element is in the second position and the first member is in the substantially vertical position, the first and second ends of each respective first element can be removably received by the first, movable member so that the first, second, third and fourth members form a substantially air-permeable tail gate for the vehicle.
