Description
- The present disclosure relates generally to luggage articles, and more specifically to a bottom frame structure for a luggage article.
- Some softside luggage cases include a frame structure or arrangement to support a luggage case. Traditional frame configurations, however, often include a one-piece bottom pan assembly, which may add unnecessary weight to the luggage case, and may limit design options. Traditional frame configurations may also include frame structures providing insufficient rigidity to the luggage case. For example, some frame structures may allow undesirable deformation of the luggage case when a user tows the luggage case from a tow handle.
- It is therefore desirable to provide an improved luggage case, and more specifically an improved frame structure that addresses one or all of the above described problems and/or which more generally offers improvements or an alternative to existing arrangements.

For example, theframe structure 260 may be operable to maintain a degree of rigidity of one or more panels of theluggage case 102 to the extent needed for holding a shape of theluggage case 102 and supporting a load therein when in use. Theframe structure 260, which may be positioned at least partially internal to theluggage case 102, may include various elements, either interconnected together, positioned separately from one another, or a combination of both. For example, theframe structure 260 may include one or more pan assemblies and/or one or more frame assemblies connected together to define a skeletal framework of theluggage article 100, as explained below. - The
frame structure 260 may be associated with only select portions of theluggage case 102. For instance, theframe structure 260 may be associated with only therear panel 112 and the bottom panel 122. Theframe structure 260 may be operable to maintain a degree of rigidity of at least therear panel 112 and the bottom panel 122 to the extent needed for holding a shape of theluggage case 102 and supporting a load therein when in use. In some examples, theframe structure 260 may be associated with therear panel 112, the bottom panel 122, and select portions of the left andright side panels 124, 126, as described below. In such examples, theframe structure 260 may not be associated with thefront panel 110, thetop panel 120, and the remaining portions of the left andright side panels 124, 126. - In this manner, the
frame structure 260 may provide sufficient strength and/or rigidity to theluggage case 102 to allow theluggage article 100 to be rolled, carried, lifted, etc. while also allowing portions of theluggage case 102 to collapse, bend, compress, etc., such as for storing of theluggage article 100. For example, theframe structure 260 may be arranged such that at least one, or portions, of thefront panel 110, thetop panel 120, theleft side panel 124, and the right side panel 126 is movable and/or deformable relative to theframe structure 260 to open, close, expand, or collapse theluggage case 102 depending on the particular application. Such configurations may also reduce the weight of theluggage article 100 compared to traditional case constructions with a full skeletal framework along each panel of the case. The examples shown and described herein are for illustrative purposes only, and theframe structure 260 may include additional frameworks and/or structural members. For instance, depending on the particular application, theframe structure 260 may include a top framework or pan assembly, a front framework, and/or additional rods or wire loops to structure the first andsecond halves - Referring to

For example, once connected together, the first andsecond pan members luggage case 102. This vertical rigidity may help limit vertical deflection of thefirst pan member 280 relative to thesecond pan member 282 along thesplit line 160, or together or separately may also help limit the vertical deflection of the combined bottom pans when secured together. As also described below, theside panel frame 272 may include a plurality of structural elements coupled together, such as elongate rods, pulltrusions, or pan structures connected together. As shown inFIG. 3 , the one ormore tubes 240 of the tow handle 224 may be attached to thebottom pan assembly 270, such as to thesecond pan member 282. - Referring to
FIG. 2 , theluggage case 102 may cover at least a portion of theframe structure 260. For example, at least portions of thebottom pan assembly 270 and/or theside panel frame 272 may be positioned within theluggage case 102 of theluggage article 100. In this manner, theframe structure 260 may be covered by the material of theluggage case 102, such as covered by softside material. In one example, theluggage case 102 may be defined by a fabric cover covering at least portions of theframe structure 260. Theframe structure 260 may be secured to theluggage case 102, such as by one or more panels, hems, pockets, loops, sleeves, etc., secured (e.g., stitched) to theluggage case 102. In examples having a hybrid case construction, theframe structure 260 may be coupled to the hardside material and/or to the softside material. For example, portions of thebottom pan assembly 270 and/or theside panel frame 272 may be formed integrally with the hardside material defining a portion of at least one panel of theluggage case 102. In some examples, theframe structure 260 may be coupled to the hardside material via fasteners, corresponding retention features, adhesive, or the like. - As shown in

In some examples, the first and secondelongate elements bottom pan assembly 270, such as with at least a portion of thesecond pan member 282. - In some examples, the first and second
elongate elements elongate elements more housing portions 530 of respective spinner wheel assemblies. The first and secondelongate elements housing portions 530, such as by adhesive, fasteners, heat or sonic welding, corresponding retention features, or the like. In some examples, the first and secondelongate elements housing portions 530. Thehousing portions 530 may be coupled to thebottom pan assembly 270 in a similar manner, such as by adhesive, fasteners, heat or sonic welding, corresponding retention features, or the like. Thehousing portions 530 may also be formed integrally with at least a portion of thebottom pan assembly 270. - With continued reference to
FIGS. 3-5 , therear frame 500 may include across frame member 540 coupling distal ends of the first and secondelongate elements cross frame member 540 may be defined as one element or more than one element. In some embodiments, thecross frame member 540 may be defined as one or more elements in combination with other structure(s) of theluggage article 100, such as with at least a portion of the tow handle 224, a bezel structure, theluggage case 102, or any combination thereof. For example, the tow handle 224 may include atop support 550 positioned distally from thebottom pan assembly 270. Thetop support 550, which may form a bezel connected to theluggage case 102, may be positioned on a distal end of one ormore tubes 240, such as spanning between a pair oftubes 240 of thetow handle 224. In such examples, thecross frame member 540 may include a pair offrame elements 560 connecting the distal ends of the first and secondelongate elements top support 550 of thetow handle 224. As shown, therear panel 112 may includecorner pieces 568 connecting theframe elements 560 to the distal ends of the first and secondelongate elements corner piece 568 may be curved and may be formed integrally with the elongate elements and/or theframe elements 560. - The
rear frame 500 may be formed from a variety of materials and means. For example, the firstelongate element 510, the secondelongate element 512, and theframe elements 560 of thecross frame member 540 may be a pulltrusion to provide a lightweight characteristic to theframe structure 260. In addition, the pulltrusion molding process may provide a composite structure of therear frame 500 that is relatively strong for its weight. The firstelongate element 510, the secondelongate element 512, and theframe elements 560 of thecross frame member 540 may include a diameter ranging between about 5mm to about 10mm (preferably between about 6mm to about 8mm), though other dimensions are contemplated depending on the size, weight, and/or strength requirements of theframe structure 260. -
FIG. 9 is an isometric view showing theluggage article 100 in a folded configuration.FIG. 10 is a schematic cross-sectional view showing theluggage article 100 in an additional folded configuration. As shown inFIGS. 9 and 10 , thefirst half 150 may be received at least partially in thesecond half 152 to reduce an overall dimension of theluggage article 100 for storage. For example, once theclosure mechanism 210 is sufficiently disengaged, the connectingedges second pan members first pan member 280 moved away from the second pan member 282 (seeFIG. 5 ). Once thefirst pan member 280 is disengaged from thesecond pan member 282, thefirst half 150 of theluggage case 102 may be positioned at least partially within thesecond half 152. For instance, thefirst pan member 280 may be positioned at least partially within thesecond half 152. In one example, such as shown inFIG. 10 , thefirst pan member 280 may fold into thesecond half 152 and overlie thesecond pan member 282 to fold theluggage article 100. As shown inFIG. 10 , thefirst pan member 280 may be folded towards thetop panel 120 and positioned at least partially within thesecond half 152, such as thefirst half 150 folding along or adjacent to the intersection between the front andbottom panels 110, 122. Depending on the particular application, thefirst pan member 280 may be tucked or rolled into thesecond half 152 such that the spinner wheel assemblies connected to thefirst pan member 280 and the spinner wheel assemblies connected to thesecond pan member 282 extend in generally opposite directions, though other positional arrangements are contemplated. Additionally or alternatively, the fabric material of thefirst half 150, such as the fabric material of at least thefront panel 110, may be folded, bunched, rolled, or otherwise compressed and positioned at least partially within thesecond half 152. In such examples, thefirst pan member 280 may be tucked or rolled under the front cover material and positioned within thesecond half 152. The compression of the fabric material of thefirst half 150 may occur generally in a top portion of thefirst half 150 due to theframe structure 260 within thefirst half 150 being positioned within only a bottom portion of thefirst half 150. - The
luggage article 100 may be formed from a variety of materials and means. For example, theframe structure 260 may be formed from a thermoplastic material (self-reinforced or fiber reinforced), ABS, polycarbonate, polypropylene, polystyrene, PVC, polyamide, and/or PE, among others. In some examples, the first and secondelongate elements frame elements 560, and/or the one ormore tubes 240 of the tow handle 224, among others, may be extruded from aluminum or other similar metal. In addition, the first and secondelongate elements frame elements 560 may be formed from fiber reinforced epoxy, resin, or other similar material. Theframe structure 260 may be formed or molded in any suitable manner, such as by plug molding, blow molding, injection molding, extrusion, casting, or the like. As noted above, theluggage article 100 may be formed from softside material and/or hardside material. The softside material may be nylon, canvas, polyester, leather, PVC, polypropylene, polyethylene, and/or PE, among others. The hardside material may be a thermoplastic material (self-reinforced or fiber reinforced), ABS, polycarbonate, polypropylene, polystyrene, PVC, polyamide, and/or PE, among others. - All relative and directional references (including: upper, lower, upward, downward, left, right, leftward, rightward, top, bottom, side, above, below, front, middle, back, vertical, horizontal, and so forth) are given by way of example to aid the reader's understanding of the particular examples described herein. They should not be read to be requirements or limitations, particularly as to the position, orientation, or use unless specifically set forth in the claims. Connection references (e.g., attached, coupled, connected, joined, and the like) are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements. As such, connection references do not necessarily infer that two elements are directly connected and in fixed relation to each other, unless specifically set forth in the claims.
