A suitcase with a tank track roller assembly comprises a first segment and a second segment. At least one of the segments is formed as a hollow generally rectangular shaped box with one open side. One segment includes a carry handle affixed to its upper extent and one segment includes a long indentation. A track roller assembly is comprised of a flexible track and a plurality of wheels. The wheels are formed in a cylindrical configuration with holes at their center. A base is formed as the lower extent of the suitcase which includes a plurality of downwardly extending members with a centrally located aperture extending therethrough. A plurality of axles is centrally positioned within the apertures in the members. Each axle has a wheel mounted on each end thereof. The track is positioned around the wheels forming an oval shaped configuration. A hinge has two generally planar rectangular wings. The wings join the first and second segments. A pull handle consists of a long cylindrically shaped rod. The rod is positioned within the indentation in one segment. The handle includes a locking mechanism adapted to allow fastening of the handle at different angles with respect to the plane of the top section.

A new and improved suitcase with a tank track roller assembly comprising, in combination: a rear segment formed as a hollow generally rectangular shaped box with parallel vertical sidewalls, a top section, a bottom section with a horizontal portion and a large back wall, the top section, bottom section with a horizontal portion and sidewalls having a small width, the rear segment having a front portion with an open end positioned opposite the large back wall, with the back wall of the rear segment having edges extending vertically below the horizontal portion of the bottom section, the rear segment also including a carry handle with coupling means on its free ends, the rear segment having an open edge including coupling means for attachment of the handle, a generally rectangular shaped buckle being centrally positioned between the carry handle and each side wall, each buckle having a portion which extends over the edge in the operative orientation; a front segment formed as a generally rectangular shaped box with a hollow interior and with parallel vertical sidewalls, a top section with an upper surface, a bottom section with a horizontal portion and a large front wall, with the top section, bottom section and sidewalls having a small width, the front segment having a back portion with an open end positioned opposite the large front wall, the large front wall having edges extending vertically below the horizontal portion of the bottom section, the top section including an open edge with upwardly extending pieces adapted to be coupled with the buckles on the rear segment, corners formed at the intersection of the top section and sidewalls having large generally rectangular shaped indentions with a long thin generally rectangular indentation with long side edges connecting the two therebetween; a track roller assembly comprised of a flexible track, a base and a plurality of wheels and axles, the wheels being formed in a generally cylindrical configuration with two flat ends having a circular hole at their center, the circumference of the wheels including a centrally located groove, the base being formed in a generally planar rectangular configuration with a plurality of centrally located downwardly extending brackets positioned equidistantly throughout its extent, each bracket including an upper screw hole and a centrally located circular hole extending therethrough, the base including a screw hole located to the side of each bracket, the brackets being cooperatively coupled to the bottom section of the rear and front segments by a short threaded bolt positioned through the aligned screw holes of the base and bracket, the wheels being coupled to each side of the downwardly extending bracket by an axle threaded through the aligned holes in the wheels and bracket, the axles including coupling means at each end to securely retain the wheels thereupon, the track being comprised of a flexible material and formed in a generally planar oval configuration with a small thickness and a width equal to that of the wheels, the track including a centrally located raised rib extending the full extent of the track, the rib adapted to fit securely within the groove in the wheels when in the operative orientation; a plurality of hinges having two generally planar rectangular wings joined by a cylindrical pivot, the pivot being positioned at the lowermost extent of the hinge, the wings of the hinges including coupling means and affixed to one side of each segment, the wings being positioned on the portion of the long side edges which extend below the horizontal portion of the bottom section of each respective segment, the hinge adapted to permit opening of the case to a ninety degree position; a pull handle consisting of a long cylindrically shaped pull handle with an upper end and a lower end, the upper end and lower end both being formed in an L-shaped configuration and contoured to fit securely within the indentations in the upper surface of the front segment, the lower end including a centrally located aperture, a pin coupled to each end of the indentation being threaded through the aperture to permit circular rotation of the lower end of the handle, the lower end of the handle also including a hole extending therethrough; and a handle assembly being located within the hollow interior of the front segment, a compression spring in the assembly being located adjacent to the lower end of the handle, the compression spring including a cylindrically shaped pin at its upper extent, a locking plate being vertically positioned adjacent to the compression spring, the plate consisting of a planar rectangular member with at least one circular hole, the plate also including the lower end of the handle affixed thereto about a pivot point, the pin portion of the compression spring being adapted to couple through the hole in the handle and a hole in the rectangular plate when positioned in alignment due to rotation of the handle, such coupling locking the handle in place to permit towing of the apparatus, the handle assembly including a cable with one of its ends being connected to the lower extent of the compression spring, a pulley wheel being positioned near one of the corners of the front segment with the cable being threaded thereupon, an L-shaped member being located at the opposite corner of the front segment, the member having apertures at both ends and at the intersection of its short and long ends, the member being mounted to one of the sidewalls at the aperture in the intersection, with the short end being coupled to the cable which extends across the large front wall of the front segment, the long end of the member being connected to a long cylindrical rod with a push button at its upper extent, the push button adapted so that when depressed the cable extends causing the compression spring below the lower end of the handle to uncouple from its locked position within the holes, thereby permitting the user to adjust the angle of the handle.
