An improved suitcase base and an improved pulling handle for use in a soft-sided suitcase and a hard-sided suitcase, giving the luggage, easy pulling characteristics. The base is nearly symmetrical in shape, with a V-shaped bottom wall forming an obtuse angle, which creates good ground clearance for the suitcase bottom under all conditions of towing over flat or uneven surfaces. Provision is made for securely latching the pulling handle while stored, and for quick, easy release from storage for pulling handle deployment. A duffle bag luggage carrier that incorporates the improved base, is also described. The improved base and quick-release pulling handle are easily adaptable to different styled soft-sided and hard-sided suitcases, and for non-suitcase luggage carriers.

Having described the invention, what is claimed is: 1. In a soft-sided suitcase, said suitcase including a rigid metal frame and a soft fabric material which is fastened to said frame at a top and sides, forming a frame enclosure with an open bottom; said frame enclosure having a sliding fastener openable portion on one side that serves as a cover; a suitcase base and pulling handle comprising: (a) a base made of a hard, rigid material, formed in a tray-like trough; said base having an open top, elongate opposing parallel planar side walls, a bottom wall, a planar front end wall and an opposing rear end wall; said bottom wall having a V shape forming an obtuse angle of approximately 163 degrees; said base including: a pair of main wheels, that are rotatably mounted transversely to said side walls on an axle and fastened to an underside of said bottom wall at a proximate midway point between said front end wall and said rear end wall; a caster wheel which is swivel mounted on said bottom wall adjacent to said front end wall; and a first latch plate which is mounted and fastened to said front end wall of said base on an outer surface midway between said side walls; said frame enclosure being placed vertically and fastened at ends of said open bottom to said open top of said base; (b) a quick-release pulling handle that is pivotably mounted on a side of said frame enclosure which is fastened to said front end wall of said base; said pulling handle being constructed with an elongate, hollow metal tube that includes plugs which are fastened in said tube, inset near each end, said plugs having an axial bore cut through their length, a handlebar which is attached to one end of said tube at an angle of 90 deg. to said tube, and two curved metal handle mounting strips that are fastened to opposing edges of a distal end of said tube, defining a "U" shaped mounting member for pivotally mounting said pulling handle; said pulling handle including a first means for latching and quickly releasing said pulling handle from a stored and latched position; and (c) second means for fixing said pulling handle rigidly in place to facilitate lifting the suitcase at a front end while pulling said suitcase. 2. The suitcase base and pulling handle as defined in claim 1, wherein said first means for latching and quickly releasing said pulling handle from a stored and latched position includes: a metal ring that is located between said handle mounting strips, a spring latch mechanism that is disposed axially inside said tube of said handle and through a center hole in said handlebar, and a wire cord connecting said ring to an end of said mechanism inside said tube; said spring latch mechanism comprising a metal rod having a tie-ring on one end and a threaded distal end; a helical compression spring, a metal washer and a latchpin, said rod being disposed in said axial bore of said second plug, with said threaded distal end extending beyond the plug, said washer and said spring being axially disposed on said rod and said latchpin screwed on to said rod at said threaded end; said latchpin normally extending beyond said handlebar and ready to be engaged by said first latch plate on said base and thereby latching said pulling handle; said pulling handle being released by pulling on said ring which is located at one end of said pulling handle and withdrawing said latchpin from said first latch plate, releasing said pulling handle and making ready for handle deployment. 3. The suitcase base and pulling handle as defined in claim 1, wherein said second means for fixing said pulling handle rigidly in place includes two elongate strut members, pivotably fastened opposing each other at one end to said pulling handle tube, and an elongate guide plate which is fastened to a side of said frame enclosure which is fastened to said front wall of said base, below the pivoting end of said pulling handle; the distal portion and distal ends of said strut members being permanently bent outwards and springy, forming a wide opening between the sides of said strut members at their distal ends, said distal ends of said strut members each including a portion permanently bent at an acute angle outward, forming fastening lips; said guide plate shaped having a wide flared lower end a narrow upper end, with side walls folded inwards having a U-shaped cross-section, sufficient to store said pulling handle against the front end of said suitcase and to catch and hold the sides and ends of said strut members when the pulling handle is deployed, said guide plate including a notch and slot in both side edges to catch and hold said fastening lips of said strut members, thereby fixing said pulling handle rigidly in place when the pulling handle is deployed. 4. The suitcase base and pulling handle as defined in claim 1, wherein said base is made of a hard plastic material. 5. The suitcase base and pulling handle as defined in claim 1, wherein said base is fabricated from a composite material. 6. The suitcase base and pulling handle as defined in claim 1, wherein said base is fabricated from a metal material.
