Claim 12

The carrier of claim 10, wherein said receiving member bar structure is a hollow, approximately 1/4 inch thick, 11/4 to 2 inch inside dimension square metal stock.

Claim 13

The carrier of claim 10, wherein said receiving member has a spring biased locking pin disposed on a top surface a predetermined distance from its proximal end for emergency mating connection with said first frame connection aperture on said connection member, said receiving member further having a locking aperture disposed on a bottom surface a predetermined distance from its distal end, said locking aperture being for lock receiving alignment with said second frame connection aperture of said connection member.

Claim 14

The carrier of claim 9, wherein said box support member is a rectilinear frame structure of predetermined peripheral dimensions and having means to secure said box member to a top surface thereof.

Claim 15

The carrier of claim 1, wherein said box member has predetermined dimensions and includes a body and has a rear opening top lid pivotally attached thereto.

Claim 16

The carrier of claim 1, further comprising a safety chain coupling said frame member to the vehicle hitch.

Claim 17

An adjustable, extensible cargo carrier for attachment to the rear portion of a vehicle via a receiver-type trailer hitch having a rectilinear tubular configuration with an open central channel of a predetermined length, comprising: (a) a stationary, non-extensible connection member for attachment to the vehicle trailer hitch, said connection member having a straight bar structure of a predetermined length and having a proximal end which is fully inserted, fixed and locked into the vehicle trailer hitch channel and an opposing distal end extending rearwardly from the vehicle, said bar structure having predetermined outside dimensions which are substantially equivalent to inside dimensions of the trailer hitch channel, said bar structure proximal end further having a reduced outside dimension; (b) a frame member slidably attached to said connection member, said frame member including a receiving member slidably connected to said connection member and a box support member attached to said receiving member, said receiving member having a straight, hollow bar structure of a predetermined length and having a proximal end for insertion over said connection member and an opposing distal end, said bar structure having predetermined inside dimensions which are substantially equivalent to outside dimensions of said connection member, said receiving member further having a hand operable locking set screw member disposed at said distal end, said set screw member being adapted to engage said connection member in said hollow receiving member and lock it in position therein, said receiving member being telescopingly slidable over said connection member, whereby said frame member is positionable on said stationary connection member with respect to the rear portion of the vehicle and is easily locked in position via said hand operable locking set screw member; and (c) a box member attached to said box support member, said box member having predetermined dimensions and including a body and at least one top lid pivotally attached thereto.

Claim 18

An adjustable, extensible cargo carrier for attachment to the rear portion of a vehicle via a receiver-type trailer hitch having a rectilinear tubular configuration with an open central channel of a predetermined length, comprising: (a) a stationary, non-extensible connection member for attachment to the vehicle trailer hitch, said connection member having a straight bar structure of a predetermined length and having a proximal end which is fully inserted, fixed and locked into the vehicle trailer hitch channel and an opposing distal end extending rearwardly from the vehicle, said bar structure having predetermined outside dimensions which are substantially equivalent to inside dimensions of the trailer hitch channel, said bar structure proximal end further having a reduced outside dimension; (b) a frame member slidably attached to said connection member, said frame member including a receiving member slidably connected to said connection member and a box support member attached to said receiving member, said receiving member having a straight, hollow bar structure of a predetermined length and having a proximal end for insertion over said connection member and an opposing distal end, said bar structure having predetermined inside dimensions which are substantially equivalent to outside dimensions of said connection member, said receiving member further having a hand operable locking set screw member disposed at said distal end, said set screw member being adapted to engage said connection member in said hollow receiving member and lock it in position therein, said receiving member being telescopingly slidable over said connection member, whereby said frame member is positionable on said stationary connection member with respect to the rear portion of the vehicle and is easily locked in position via said hand operable locking set screw member; and (c) a box member attached to said box support member, said box member having predetermined dimensions and including a body and at least one top lid pivotally attached thereto.

Claim 19
