DETAILS DESCRIPTION

[0022] In this specification and the claims which follow, spatial terms such as vertical, horizontal, up, down, above, and below may be used with respect to the normal orientation of the suitcase. For example, if the suitcase has wheels, then the normal orientation is with its wheels on the ground. In any event, these terms are not intended to be limiting or absolute.

[0023] Throughout this specification and the claims which follow, the word comprise and variations such as comprises and comprising, will be understood to mean that the following integer, step, group of integers or group of steps is included but that other integers, steps, groups of integers or groups of steps are not excluded.

[0024] A frame assembly for a suitcase panel may be a structure made up of rigid, or substantially rigid, components which supports a panel of a suitcase. The frame assembly may give shape to the suitcase panel. The frame assembly may comprise all of the components that are required to give a suitcase panel its structural integrity. A suitcase panel comprising the frame assembly, together with other suitcase panels, may define a volume for storing belongings inside the suitcase.

[0025] The frame assembly may be constructed from components that are secured together so that no components will fall off the frame assembly, and the frame assembly will not fall apart, regardless of the orientation in which the frame assembly is held. This may be true even if the frame assembly is not stitched into a covering. Alternatively, some frame assemblies may require that they are stitched into at least a section of the covering to prevent them from falling apart, and to prevent one or more components from falling off the frame assembly.

[0026] A frame assembly may not require a covering to be held together. That is, the frame assembly may have structural integrity without a covering. Stated another way, the frame assembly can be securely assembled independently of a covering. As will be explained in more detail below, in some embodiments component(s) of a frame assembly may comprise features such as internal protrusions(s) or adhesive or other fastening means to allow the components of the frame assembly to be held together in place.

[0027] A suitcase panel covering can be made of flexible material. A suitcase panel covering may be made entirely from flexible material other than some of the fastening means that may be attached to a suitcase panel covering. A suitcase panel covering may enclose a whole frame assembly when fixed together.

Suitcase and Suitcase Panel

[0028] FIG. 1 shows a front perspective view of a suitcase 1 according to an embodiment of the present disclosure. The suitcase 1 is cuboidal in shape. The suitcase 1 comprises a front panel 10, a first side panel 20, a top panel 30, a second side panel (not shown) which is opposite to first side panel 20, a back panel (not shown) which is opposite to front panel 10, a bottom panel (not shown) which is opposite to top panel 30, a handle 40, and wheels 50. The front panel 10 may correspond to a lid of the suitcase 1, and the lid may include one or more fastening members 11, 12 which can be provided in the form of zips to allow the lid to be at least partially removably connected to the remaining panels of suitcase 1.

[0029] Each of the front panel 10, first side panel 20, top panel 30, second side panel, back panel, and bottom panel of the suitcase 1, in particular the front panel 10, may comprise a frame assembly (not shown) and a covering 15 extending over the frame assembly. In this embodiment, the covering 15 is secured to the frame assembly. The covering 15 may comprise a single piece of material or a plurality of pieces of flexible material (e.g. an outer layer and an inner lining) fixed together, for example by being stitched together. In some embodiments, covering 15 can be described as single-piece. That is, while it is made up from a plurality of pieces of flexible material which have been fixed together, it is one combined piece to which the frame assembly may be secured. The covering 15 may be dimensioned so that it is held taut by the frame assembly when the frame assembly is attached to the covering 15. When the frame assembly is secured to the covering 15, the covering 15 can extend over the entirety of the frame assembly and enclose the frame assembly. Also, in some embodiments, the covering 15 may be made entirely of flexible material. Usually, a fabric material is used, and in particular polyester, nylon, cotton, leather, vinyl and other fabrics that are lightweight, durable and flexible.

[0030] The handle 40 may be directly connected to a structure of the back panel of suitcase 1. For example, in some embodiments, the handle 40 may be part of an integrated handle assembly (not shown) which is connected to a frame assembly of the back panel. Each wheel 50 is positioned at a respective corner of the bottom panel of the suitcase 1, and is capable of freely rotating about an axis perpendicular to the bottom panel to enable suitcase 1 to be easily steered during use.

[0031] While suitcase 1 of FIG. 1 is understood as having four wheels (three of which are explicitly shown), it is not necessary for suitcases of the present disclosure to have any wheels, and different numbers of wheels are possible. In particular, suitcases of the present disclosure may have two wheels and optionally at least one support member. Also, while the suitcase 1 is illustrated as having a handle, it is not necessary for suitcases of the present disclosure to have a handle at all.

Frame Assembly

[0032] FIG. 2 shows a front view of a frame assembly 100 according to an embodiment of the present disclosure. Frame assembly 100 is a quadrilateral frame comprising a first frame corner component 110A, a second frame corner component 110B, a third frame corner component 110C, a fourth frame corner component 110D, a first support rod 120A, a second support rod 120B, a third support rod 120C, and a fourth support rod 120D. Each frame corner component 110A-D is configured to connect two respective support rods so as to form the quadrilateral frame. Description of the frame corner components 110A-D and the contact between each frame corner components and two respective support rods will be provided in more detail under the section Frame Corner Component. In some parts of this disclosure, each of the first to fourth frame corner components may be generally referred to as a frame corner component 110, and each of the first to fourth support rods 120A-D may be generally referred to as a support rod 120.

[0033] Each of the first, second, third, and fourth support rods 120A-D may comprise fiberglass. In some embodiments, each of the first to fourth support rods 120A-D may be a fiberglass pultrusion rod. Other materials may be used instead or in combination with fiberglass if this is desirable. Each support rod 120A-D has a first and second end. By connecting the first and second ends to respective frame corner components, frame assembly 100 is formed.

[0034] In more detail, when the frame assembly 100 is fully formed, the first support rod 120A connects the first and second frame corner components 110A, 110B, the second support rod 120B connects the second and third frame corner components 110B, 110C, the third support rod 120C connects the third and fourth frame corner components 110C, 110D, and the fourth support rod 120D connects the fourth and first frame corner components 110D, 110A. Specifically, each end of each support rod 120A-D connects to a respective frame corner component through respective connection portions at the frame corner components. Furthermore, each end of each support rod 120A-D is received within a respective connection portion when frame assembly 100 is fully formed. Fastening means such as adhesive can be used to keep the ends in place within respective connection portions, as will be explained in further detail below.

[0035] The frame assembly 100 is a fully formed frame assembly, in that it contains all the rigid, or substantially rigid, components necessary to support a covering (e.g. the covering 15 of FIG. 1) and give shape to a suitcase panel (e.g. the front panel 10 of FIG. 1).

[0036] When the frame assembly 100 is assembled as shown in FIG. 2, the frame assembly 100 has structural integrity. That is, components of frame assembly 100 are sufficiently secured together that no components will fall off the frame assembly 100, regardless of the orientation in which the frame assembly 100 is held. That can be true even if the frame assembly 100 is not fixed to a covering (e.g. the covering 15 as shown in FIG. 1). The frame assembly 100 may comprise all of the components that are required to give a corresponding suitcase panel its structural integrity and maintain its shape. In some embodiments, features such as an internal protrusion on an internal surface of a connection portion of a frame corner component can be used to maintain the ends of the support rods in place within respective connection portions, such that structural integrity of frame assembly 100 can be maintained or improved.

[0037] As mentioned above, a covering (e.g. the covering 15) can extend over the frame assembly 100 to form a suitcase panel, such as the front panel 10. In more detail, the frame assembly 100 can be fixed to one or more sections on an interior side of the covering 15. For coverings that include at least an outer layer (such as a strong durable fabric made of nylon) and an inner lining, the interior side may correspond to the inner lining, meaning that the frame assembly 100 can be fixed to the inner lining by being stitched inside or underneath one or more sections of the inner lining. For example, the frame assembly 100 may be stitched between the inner lining fabric and the outer layer fabric. By fixing the frame assembly 100 to an interior side of the covering 15, rather than the exterior side, the frame assembly 100 is better protected from high impact forces or heavy loads.

Frame Corner Component

[0038] As described above and illustrated in FIG. 2, the frame assembly 100 comprises four frame corner components 110A, 110B, 110C, 110D. These frame corner components 110A-D are lightweight while still being strong and robust enough to survive rough handling. In some embodiments, each frame corner component 110 may comprise fiberglass. Each frame corner component 110 may be moulded, for example by injection moulding, or 3D printed, or formed by an alternative manufacturing technique if this is desirable.

[0039] As best illustrated FIGS. 3 to 6, each frame corner component 110 in the present embodiment comprises a body 111 joining a first connection portion 112 and a second connection portion 113. Furthermore, in the present embodiment, each frame corner component 110 comprises a first end 114 and a second end 115, where first connection portion 112 corresponds to the first end 114 and the second connection portion 113 corresponds to the second end 115.

[0040] As mentioned above, each support rod 120 in frame assembly 100 comprises a first end and a second end, and when the frame assembly 100 is fully formed, the first and second ends of each support rod 120 are received in the openings of respective connection portions of the frame corner components 110 the frame assembly 100 is constructed. Each opening may be in the form of a blind hole, specifically a hole that is blind along an axis of the connection portion. This is illustrated in FIG. 3 which shows that the first connection portion 112 comprises an opening 116 configured to receive an end of a respective support rod, and the second connection portion 113 comprises an opening 117 configured to receive an end of a respective support rod (not shown). Taking the first frame corner component 110A as illustrated in FIG. 2 as an example, the opening 116 of first connection portion 112 of the first frame corner component 110A may be configured to receive an end of first support rod 120A, and the opening 117 of the second connection portion 113 of this frame corner component 110A may be configured to receive an end of fourth support rod 120D. The opposite arrangement is also possible, where the opening 116 of the first connection portion 112 may be configured to receive an end of fourth support rod 120D, while the opening 117 of the second connection portion 113 may be configured to receive an end of first support rod 120A.

[0041] In the present embodiment as shown in FIGS. 3 to 8, each of first connection portion 112 and second connection portion 113 comprises four apertures. More specifically, first connection portion 112 comprises a first pair of apertures 118A, 118B and a second pair of apertures 118C, 118D, and the second connection portion 113 comprises a third pair of apertures 119A, 119B, and a fourth pair of apertures 119C, 119D. The relative positions of the first pair 118A, 118B and second pair 118C, 118D of apertures of the first connection portion 112 are best illustrated in FIG. 5, while the relative positions of the third pair and fourth pair of apertures at second connection portion 113 are best illustrated in FIG. 8.

[0042] As shown in FIG. 5, the first pair of apertures 118A, 118B are arranged on a first side of the first connection portion 112, while the second pair of apertures 118C, 118D are arranged on a second side of the first connection portion 112, the second side being opposite to the first side. The first pair of apertures include a first distal aperture 118A and a first proximal aperture 118B. The second pair of apertures include e a second distal aperture 118C and a second proximal aperture 118D. The positions of the first and second distal apertures 118A, 118C are symmetrical with respect to a central lateral axis of first connection portion 112, and the positions of the first and second proximal apertures 118B, 118D are symmetrical with respect to the central lateral axis of the first connection portion 112. This symmetry in positions makes the frame corner component easy to manufacture, and thereby reduces the associated manufacturing costs. However, alternative arrangements are possible.

[0043] Similarly, as shown in FIG. 8, the second connection portion 113 comprises a third pair of apertures 119A, 119B, and a fourth pair of apertures 119C, 119D. The third pair of apertures include a third distal aperture 119A and a third proximal aperture 119B, and the fourth pair of apertures include a fourth distal aperture 119C and a fourth proximal aperture 119D. The third pair of apertures 119A, 119B are arranged on a first side of the second connection portion 113, and the fourth pair of apertures 119C, 119D are arranged on a second side of the second connection portion 113, the second side being opposite to the first side. The positions of the third and fourth distal apertures 119A, 119C are symmetrical with respect to a central lateral axis of second connection portion 113, and the positions of the third and fourth proximal apertures 119B, 119D are symmetrical with respect to the central lateral axis of the first connection portion 113.

[0044] Each of the apertures 118A-D, 119A-D is configured to allow access to at least a part of a support rod when the respective support rod is received in the opening of the respective connection portion. For example, referring to FIG. 6, it is shown that a support rod 120 is resting within the opening 116 of the first connection portion 112. In this example, the second pair of apertures 118C, 118D of first connection portion 112 can allow access to at least at part of the support rod 120, such that adhesive 140 can be applied through the apertures 118C, 118D to a contact area or contact areas between the first connection portion 112 and the support rod 120, in particular contact areas adjacent to the apertures 118C, 118D. The adhesive 140 may be liquid adhesive, for example. The same applies to the first pair of apertures 118A, 118D and also to apertures positioned at the second connection portion 113.

[0045] The apertures may be specifically dimensioned to allow the adhesive 140 to be applied to a contact area between the support rod that is received within a respective opening and an internal surface of the respective opening. For example, each aperture may be dimensioned to have a diameter that is proportionate with respect to the size of a nozzle of a typical bottle of liquid adhesive. In some embodiments, each aperture may have a diameter within any one of the following ranges: 1 mm to 10 mm, optionally 2 mm to 5 mm, further optionally 3 mm to 4 mm. Hence, in some embodiments, at least one of the first and second portions 112, 113 of the frame corner component 110 may comprise applied adhesive 140 at one or more contact areas adjacent to the aperture, the one or more contact areas being between the internal surface of the respective opening and the support rod 120 that is received within the respective opening. The use of adhesive instead of other fastening means such as screws, rivets, and bolts can help further reduce the weight of the frame assembly and therefore the suitcase panel comprising the frame assembly, and can also improve the ease of manufacture of the frame.

[0046] By providing two apertures on each side and arranging the two pairs of apertures on opposite side of a connection portion, multiple different points of access are provided which increases the convenience of applying or injecting adhesive into the apertures, thereby speeding up the process of manufacturing or constructing the frame assembly, which in turn facilitates the process of manufacturing a corresponding suitcase panel. Furthermore, the provision of more than one aperture along the connection portion on each side allows adhesive to be injected or applied at different areas of contact between a respective support rod and the internal surface of the opening of the respective connection portion, thus improving the bonding strength between the connection portion and the support rod.

[0047] In some embodiments, the opening of a connection portion may comprise an internal protrusion that is configured to engage an external surface of a respective support rod when the respective support rod is received in the opening, so as to maintain the end of the respective support rod in place. For example, as best illustrated in FIG. 6, the opening 116 of the first connection portion 112 comprises a first internal protrusion 130, which is formed on an internal surface of the opening 116. FIG. 6 in particular show an end of a support rod 120 being received in the opening 116 of the first connection portion 112 of the frame corner component 110. In this case, the first internal protrusion 130, which may be formed at a position between the first/second distal apertures 118A,118C and the first/second proximal apertures 118B, 118D, can engage an external surface of the support rod 120 to maintain the end of the support rod 120 in place. Similarly, as shown in FIGS. 7 and 8, the opening 117 of the second connection portion 113 also comprises a second internal protrusion 131, which may be formed at a position between the third/fourth distal apertures 119A, 119C and the third/fourth proximal apertures 119B, 119D. When an end of a support rod 120 is received in the opening 117. The second internal protrusion 131 can engage an external surface of the support rod 120 to maintain the end of the support rod 120 in place.

[0048] In the present embodiment, each of the first and second internal protrusions 130, 131 is provided in the shape of a ridge. This is best illustrated in FIG. 7 which shows the second internal protrusion 131 as a ridge that is formed along a section of an inner circumference of the opening 117 of the second connection portion 113. More specifically, in the present embodiment the internal protrusion is formed along at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 100% of the inner circumference of the opening of the connection portion-this arrangement provides increased surface area contact between the internal protrusion 131 and an external surface of the respective support rod received in the opening, thus improving the grip of the internal protrusion (and the opening) on the support rod. Nevertheless, it will be appreciated that, in alternative embodiments, one or more internal protrusions may be provided in other shapes, forms and dimensions, and they may be arranged at different positions along the internal surface of the respective opening if desired.

[0049] Furthermore, the first and second internal protrusions 130, 131 may be integrally formed on the internal surface of respective openings, for example by a moulding process, for example an injection moulding process. The first and second internal protrusions 130, 131 may be formed using a process that does not involve hammering, or denting, or applying a force to an external surface of any part or component of the frame corner component 110.

[0050] By providing one or more internal protrusions at the connection portion(s), respective ends of support rods can be at least temporarily held in place while fastening means such as adhesive is applied. For example, the first and second internal protrusions 130, 131 can hold respective ends of the support rods in place while adhesive 140 is applied or injected (via the apertures) to contact areas between the support rod and an internal surface of the opening of the respective connection portion. This arrangement helps prevent situations in which the adhesive loses its effectiveness or adhesive properties due to unwanted or unexpected movement of the support rod with respect to the connection portion before it dries and bonds the areas of contact between the external surface of the support rod and the internal surface of the opening.

[0051] Although not shown in the drawings, in some embodiments at least one end of each support rod 120 may comprise a groove on the external surface, the groove having a corresponding position to an internal protrusion of a connection portion 110 that is configured to receive the respective support rod 120. Furthermore, the groove may have a complementary shape to the internal protrusion of a connection portion 110. In these embodiments, when the support rod 120 is received in the opening of the respective connection portion, the internal protrusion 130, 131 engages the groove at the end of the support rod 120 to maintain the support rod 120 in place.

[0052] Although the embodiment as illustrated in FIGS. 3 to 8 show that each connection portion of frame corner component 110 comprises four apertures to allow access to a support rod 120 received in the opening of the respective connection portion, it will be appreciated that in other embodiments a single aperture or other numbers of apertures at a connection portion are possible. For example, in an alternative embodiment, each connection portion may only comprise a single aperture. It will also be appreciated that in other embodiments, apertures may be omitted entirely for some or all of the connection portions.

[0053] Although the embodiment as illustrated in FIGS. 6 to 8 show that the opening of each connection portion comprises an internal protrusion, it will be appreciated that in alternative embodiments internal protrusions can be entirely omitted. It will also be appreciated that in alternative embodiment internal protrusions may be positioned at different locations of the opening of a connection portion, if desired. Furthermore, in some embodiments, more than one internal protrusion may be provided in the opening of one or more connection portions, in order to strengthen the connection between a connection portion 110 and a respective support rod 120. In a further embodiment, protrusions may instead be provided on one or more support rods, and in this embodiment grooves may optionally be provided on the internal surface of one or more respective connection portions.

[0054] Although frame corner component 110 is shown in the present embodiment to include a body 111 (e.g. as shown in FIG. 3), in alternative embodiments, a frame corner component 110 may not comprise a body. In these embodiments, the first connection portion 112 may be directly connected to the second connection portion 113 at the frame corner component 110. As shown, body 111 may take the form of a smooth continuous curve between the first connection portion 112 and the second connection portion 113, but other configurations are possible.
