Claim 1
Independent Claim
223 words
A mounting assembly for use in supporting a loading ramp from a truck tailgate in an operative position inclined rearwardly and downwardly when the tailgate is in an open position and also in a manner allowing the ramp to be swung to a stored position overlying the inner surface of and supported from the tailgate when the latter is in its raised closed position, said mounting assembly comprising an elongated guide member including means carried by its opposite end portions for securement to the inner surface of a tailgate adjacent the free swinging edge portion thereof, a pair of followers slidingly disposed on said guide member for movement therealong and also supported from said guide member for rotation thereabout, a pair of anchor members for support from opposite side portions of one end of a loading Ramp, one of said anchor members being oscillatably supported from one of said followers for angular displacement relative thereto about an axis disposed generally normal to said guide member, the other anchor member being readily removably secured to the other follower, a third anchor member for securement to the side portion of the other end of said loading ramp corresponding to the side portion thereof from which said other anchor member is to be secured, said third anchor member being readily removably securable to said other follower.
Claim 2
Dependent Claim
223 words
A mounting assembly for use in supporting a loading ramp from a truck tailgate in an operative position inclined rearwardly and downwardly when the tailgate is in an open position and also in a manner allowing the ramp to be swung to a stored position overlying the inner surface of and supported from the tailgate when the latter is in its raised closed position, said mounting assembly comprising an elongated guide member including means carried by its opposite end portions for securement to the inner surface of a tailgate adjacent the free swinging edge portion thereof, a pair of followers slidingly disposed on said guide member for movement therealong and also supported from said guide member for rotation thereabout, a pair of anchor members for support from opposite side portions of one end of a loading Ramp, one of said anchor members being oscillatably supported from one of said followers for angular displacement relative thereto about an axis disposed generally normal to said guide member, the other anchor member being readily removably secured to the other follower, a third anchor member for securement to the side portion of the other end of said loading ramp corresponding to the side portion thereof from which said other anchor member is to be secured, said third anchor member being readily removably securable to said other follower.
Claim 3
Dependent Claim
28 words
The combination of claim 1 wherein said elongated guide member comprises a cylindrical member, said followers each including sleeve portions slidably and rotatably mounted on said guide member.
Claim 4
Dependent Claim
44 words
The combination of claim 2 wherein each of said sleeve members includes an integral pivot pin portion projecting outwardly therefrom at generally right angles relative thereto, said anchor members each comprising an eye member rotatably and telescopically receivable over the corresponding pivot pin portion.
Claim 5
Dependent Claim
35 words
The combination of claim 3 including retaining means readily removably engageable with each of said pivot pin portions outwardly of the corresponding eye member for releasably securing said eye members on said pivot pin portions.
Claim 6
Dependent Claim
33 words
The combination of claim 1 wherein said means carried by the opposite end portions of said guide member define opposing sockets in which the opposite ends of said guide member are captively retained.
Claim 7
Dependent Claim
48 words
The combination of claim 1 wherein said assembly further includes an abutment member for securement to a hinged lateral extension of said loading ramp and to be carried by the end of the free swinging edge portion of the ramp extension for abutting engagement with said guide member.

Dependent Claim
162 words
In combination with a vertically swingable vehicle tailgate, an elongated ramp structure, an elongated guide member supported from and extending along the free swinging edge of said tailgate, a pair of followers slidably and oscillatably mounted on said guide member for movement therealong and angular displacement about axes generally paralleling said guide member, said ramp including opposite end and opposite side marginal portions, the opposite ends of one of said end marginal portions including first and second attaching means readily releasably attached to said followers, said first attaching means and the corresponding follower including coacting means attaching the first attaching means to the corresponding follower for angular displacement of the ramp relative to the follower about an axis disposed generally normal to said axes, and third attaching means carried by the other end of said ramp at the side thereof from which the first attaching means is supported readily releasably attachable to the follower to which the first attaching means if attached.
Claim 9
Dependent Claim
162 words
In combination with a vertically swingable vehicle tailgate, an elongated ramp structure, an elongated guide member supported from and extending along the free swinging edge of said tailgate, a pair of followers slidably and oscillatably mounted on said guide member for movement therealong and angular displacement about axes generally paralleling said guide member, said ramp including opposite end and opposite side marginal portions, the opposite ends of one of said end marginal portions including first and second attaching means readily releasably attached to said followers, said first attaching means and the corresponding follower including coacting means attaching the first attaching means to the corresponding follower for angular displacement of the ramp relative to the follower about an axis disposed generally normal to said axes, and third attaching means carried by the other end of said ramp at the side thereof from which the first attaching means is supported readily releasably attachable to the follower to which the first attaching means if attached.
Claim 10
Dependent Claim
