Abstract

A luggage case having a large pocket (40) carried by the main packing door (30). The pocket is formed by portions of the rail (20) releasably attached to the main case by a sinuous path zipper track (32), and a gusset (44) along the lower, self hinged portion (34) of the door. The resulting compartment protrudes into the interior of the case, and over at least one of the wheels (26), thus providing good organization within the case while helping to keep the case balanced on the wheels.

Description

SOFTSIDE LUGGAGE CASE HAVING A SINGLE PERIPHERAL FRAME AND TWO SIDE-BY-SIDE COMPARTMENTS

Background of the Invention This invention relates to so-called pullman cases-luggage cases with two or more wheels arrayed along one elongated side. This particular style of pullman has a so-called drum construction, that is, a relatively rigid frame extending around the perimeter or rail, that is the four narrow sides of the case. Each of the opposite front and back sides are closed by a flexible textile membrane. One of these sides is usually releasably attached to the framed perimeter by a zipper or the like. Most such cases include a main packing compartment and at least one small zippered compartment, usually accessible from the outside of the zippered side or door. This zippered pocket on the door usually consists of nothing more than a narrow envelope of fabric receiving only the smallest amount of clothing and the like. Alternatively, such pullman cases have had a gusseted pocket that protrudes from 2 to 6 centimeters beyond the overall peripheral dimension of the case. This gives at least the illusion that the combination of this gusseted pocket and the main compartment has enhanced packing capacity. There are many problems with these prior designs. The slit pocket in the door has very little packing space, leaving most of the packing space in one very large compartment that may be difficult for the traveler to organize. Also, once packed, the very deep main compartment presents a formidable obstacle to finding an article that has been packed. The pullman cases with the large gusseted pockets present a better organization scheme. However, such gusseted compartments, since they project beyond one side of the framed rail, can result in an imbalance, perhaps causing the case to tip towards the packed and protruding pockets.

A third alternative case provides for a packing scheme that divides the main packing compartment in two. This case uses two frames parallel with one another and separated by the zippered access that divides this main compartment. In this way, such a pullman luggage case would be divided approximately in half at a plane parallel to the rail and through the center of the rail, and each of the two resulting compartments would have a frame running around its periphery. Such a case could have wheels, one or two, on each of these framed compartments. This generally would require a sturdy hinge connecting the two compartments so that the case would stand erect when the two compartments were zipped face to face.

Such a case, unfortunately, has several disadvantages. First, it tends to be heavier than a single frame case because of the extra frame. Secondly, the extra cost and complexity of this more complex construction has made such a case less popular than the traditional lid-opening pullman case described previously.

Brief Description of the Invention Accordingly, this invention comprises an overall luggage construction that utilizes a single plastic or metal peripheral frame and an otherwise conventional drum construction to form the main body of the luggage case. However, instead of the usual flat lid zipped on to one edge of the peripheral rail, the subject invention provides a case that zips to the main body along a sinuous path or on an angled connecting plane. The zippered attachment releasably attaches the top and two side edges of the lid and the lid is self-hinged to the main body of the case along or near the intersection of this lid face and the bottom side of the rail where wheels or glides are attached. The zipper path runs from this self-hinged edge and curves towards a central dividing plane of the rail to define a second compartment (in addition to the main compartment to which it is releasably attached) having a substantial depth. Thus, the lid comprises the one side face and three walls, the walls spanning the ends and top of the lid. The depth of these walls of the lid compartment comprises ideally one-third of the total width (or depth) of the overall luggage case. The fourth wall of the case can be closed by a textile gusset usually made of lining material (in contrast with the case body material which forms the front face or lid and the three side walls mentioned above). A light, stiff material, such as a polyethylene sheet, holds the shape of these three walls and the gusset formed by the lining material. These stiffening plastic layers, however, do not constitute a structural frame. When the lid is closed, this fourth gusset wall rests on the bottom board of the rail, and is thus inboard of, or at least positioned over, one set of wheels in the case of a pullman case.

Detailed Description of the Preferred Embodiment Figure 1 shows a perspective view of a pullman case 10 in accordance with the instant invention. Shown here are the fixed axis wheels 12 and 14 at the lower rear comer of the luggage case. Preferably another pair of wheels, such as caster wheels 16, 18 of a known construction (shown by dashed lines in Figure 1 , and from the front end of the case in Figure 4), are positioned at the forward lower corners of the case so that the case can be pulled on all four wheels, or alternatively, the front corner of the case can be lifted and the suitcase wheeled on just the two back wheels as shown. The rail 20 extends around the rest of the periphery of the case, having a frame 22 (see Figure 2) that structurally stabilizes this rail and thus the rest of the case. The bottom of the case is made structurally stable by an interior bottom board 24 (Figure 2) and a molded bezel 26 that holds and positions each pair of wheels (see Figures 3 and 4). The back wall 40 is attached to the rail along one edge to form a main packing compartment. The main packing door 30 is attached to the rail by a main access slide fastener or zipper 32. The zipper track of the main zipper 32 is sewn, using conventional means, along a path that divides the rail and defines about one-third of the total width of the rail around three of the four sides of the rail. Note that the zipper track curves away from this one-third/two-thirds path to intersect the edge of the lid face of the case at the intersection 34 of the bottom side of the rail and the face of the lid 30. In this embodiment, the lid also includes an additional slit pocket accessed from the outside by conventional zipper 38. While the zipper track 32 is shown to take a sinuous or curving path at 33, this path could also be generally straight in this region 33, forming a diagonal line between the self hinging portion 34 and the straight path nearer the center line of the rail. In this way, a substantial portion of the rail, at least along the top and side portions, forms substantial portions of the main packing door.

Figures 5 and 6 show this main access zipper in the open condition. The two- thirds/one-third split is clearly shown, as is the construction of the gusseted compartment wall within the case. The single narrow frame 22 of conventional rolled steel or extruded extends along the center line of the rail 20 and around the inside of the rail 20 and the bottom of the case includes a wider board 24 that extends from the intersection of the front face of the case to the rear face of the case.

Figure 3 shows a detail of the hinged portion of the main packing door. As can be seen, the zipper track 32 is at the intersection of each of these zipper tracks. The interior textile gusset wraps around the corner and has an interior wall attached around to its inner face. This inner wall has its own zipper access as well. Figure 5 shows an interior view of the same corner shown in Figure 4. Clearly seen in this view is the peripheral frame passing around the inside of the rail. The bottom board extends underneath this frame as is conventional, all the way out to the terminal ends of the main access zipper.

Figure 6 shows a detail from the rear side of the case showing the depth of the interior rail and its relationship to the curving zipper track. A stiffening material, such a as a conventional thin sheet 46 of polyethylene, is positioned within the otherwise flaccid cloth gusset 44 that the full volume of this door compartment can be easily utilized by the traveler. The path of the most interior corner 45 of the gusset 44 is shown by the dashed arrow line. Note how the volume defined by the second compartment 40 is thus positioned over the wheel 14, and the traveler's goods in the compartment 40 would thus be supported by the wheels 14 thereunder. This construction permits easy and organized packing, but does not encourage over packing and unbalancing of the case. In contrast with other pullman and even upright style cases which offer one or a series of gusseted auxiliary packing pockets protruding from the side of the case, the instant invention keeps such potentially unbalanced loads to a minimum, and does this with only a single perimeter frame such as frame 22 for structural stability.

Figure 4 clearly shows the unique sinuous path which the main access zipper forms at each of its terminal ends. This sinuous path is most striking at the front and rear corners of the main access door where it curves through a path that first is parallel to the front and rear faces of the case, then bends smoothly towards the front face, continues at an acute angle and then curves again as it approaches the front face to be parallel to the front face, terminating at the self-hinged portion as mentioned above. Figure 3 shows this sinuous path continuing around the rounded corner that characterizes the drum construction of the basic case, and terminates where the bottom board flattens out. While the invention is described in terms of a pullman case execution, it should be understood that this concept could be applied to roll-on cabin luggage, so-called upright luggage (where the main access is in the vertical direction), soft business cases, and beauty cases.
