Claim 9

In a motor vehicle and the like having a bumper member rigidly attached to the main frame thereof, an improvement for rigidly but removable mounting adapters to the bumper member wherein the adapter can be in the form of a plurality of flat elongated arms extending in a common direction perpendicular to at least one cross-bar which interconnects the adapter arms and wherein each said arm is of a common rectangular cross-section and has a bore transversely therethrough comprising: a plurality of assemblies each having sidewalls defining an elongated slot of a rectangular cross-section with said slots each being dimensioned for receiving one of the adapter arms in closely-fitting relation, each said assembly having a wall portion adjacent said bumper configured to conform to the shape of the surface of said bumper on the side thereof away from the main frame, means rigidly attaching said assemblies integrally with the bumper member so that said slots terminate in rectangular openings in a common plane exteriorly of the bumper member on the side away from the main frame in fixed, rigid relation to said main frame, the length of said rectangular opening being generally parallel to the length of the bumper member, said slot assemblies each having a hole through said sidewalls thereof perpendicular to the length of said rectangular cross-section with said hole being externally accessible relative to the bumper member, said hole being positioned for aligning with an adapter arm bore when the associated adapter arm is inserted into said slot, and means cooperating with said holes and the adapter bores aligned therewith for securing the adapter arms internally in the receiving said slots.

Claim 10

In a motor vehicle and the like having a bumper member rigidly attached to the main frame thereof, an improvement for rigidly but removable mounting adapters to the bumper member wherein the adapter can be in the form of a plurality of flat elongated arms extending in a common direction perpendicular to at least one cross-bar which interconnects the adapter arms and wherein each said arm is of a common rectangular cross-section and has a bore transversely therethrough comprising: a plurality of assemblies each having sidewalls defining an elongated slot of a rectangular cross-section with said slots each being dimensioned for receiving one of the adapter arms in closely-fitting relation, each said assembly having a wall portion adjacent said bumper configured to conform to the shape of the surface of said bumper on the side thereof away from the main frame, means rigidly attaching said assemblies integrally with the bumper member so that said slots terminate in rectangular openings in a common plane exteriorly of the bumper member on the side away from the main frame in fixed, rigid relation to said main frame, the length of said rectangular opening being generally parallel to the length of the bumper member, said slot assemblies each having a hole through said sidewalls thereof perpendicular to the length of said rectangular cross-section with said hole being externally accessible relative to the bumper member, said hole being positioned for aligning with an adapter arm bore when the associated adapter arm is inserted into said slot, and means cooperating with said holes and the adapter bores aligned therewith for securing the adapter arms internally in the receiving said slots.

Claim 11

In a vehicle adapter attachment in accordance with claim 8, said plurality of assemblies including at least four said assemblies, said rigidly attaching means including means positioning said four assemblies for defining the corners of a rectangle in said common plane, said cooperating means including a pair of shafts each dimensioned for fitting through the bores in a pair of said assemblies.

Claim 12

In a vehicle adaptor attachment improvement in accordance with claim 8, said cooperating means including a plate member and a shaft rigidly attached to said plate member in extending relation thereto with said shaft being dimensioned for fitting through the aligned said hole and bore, said plate member having a passage opening therethrough, at least one of said assemblies including an element rigidly attached thereto in externally extending relation and including means cooperatively alignable with said plate member passage for allowing locking said plate member to said assembly.

Claim 13

In a bumper hitch apparatus for attaching an accessory to the frame of a vehicle and the like, a bumper comprising an elongated frame including at least three elongated slotted passageways extending transversely of the length of said frame and in a horizontal direction, two of said passageways oriented on a common horizontal line and the other of said passageways oriented in spaced vertical relation to said line, said passageways each having parallel top and bottom walls including bores extending vertically through said frame to intersect said passageways, one of said top and bottom walls of each of said passageways being coextensive with a portion of said bumper.

Claim 14

In a bumper hitch apparatus for attaching an accessory to the frame of a vehicle and the like, a bumper comprising an elongated frame including at least three elongated slotted passageways extending transversely of the length of said frame and in a horizontal direction, two of said passageways oriented on a common horizontal line and the other of said passageways oriented in spaced vertical relation to said line, said passageways each having parallel top and bottom walls including bores extending vertically through said frame to intersect said passageways, one of said top and bottom walls of each of said passageways being coextensive with a portion of said bumper.
