Description

Technical Field

[0001] The present invention relates to the field of luggage trunks, in particular to luggage trunks which can be moved by rolling via a set of casters.

[0002] It should be noted that luggage can be distinguished from suitcases and other smaller luggage items. Thus, luggage is known to be defined as a large rigid piece of luggage. In particular, luggage is typically larger (taller and longer) and more rigid than a suitcase and has a parallelepiped shape. Background Art

[0003] The prior art includes descriptions of luggage pieces and methods for manufacturing such luggage pieces, characterized by the steps of assembling a frame, for example a frame consisting of corner pieces defining a substantially parallelepiped structure to which panels are then assembled to form a box, and a cover allowing the luggage piece to be opened and closed.

[0004] Document EP3476241A1 describes such an assembly method for a luggage piece of this type. However, a luggage piece of this type is not a suitcase and does not have a comparable structure.

[0005] There is also a need for larger pieces of luggage, in other words, suitcases. A suitcase can transport a larger volume and mass and is usually designed to be more sturdy and durable. This means that the suitcase is very sturdy. The sides of this type of suitcase are parallel to each other, and the adjacent sides form a right angle. The edges of this type of suitcase need to be protected by sockets that strengthen these edges.

[0006] However, it is difficult to ensure the rigidity and flexibility required for such luggage.

[0007] The object of the present invention is to provide a luggage case having both high rigidity and moderate flexibility. Therefore, the luggage case according to the present invention is strong and durable. The present invention also relates to a method for manufacturing such a luggage case. Summary of the invention

[0008] More precisely, the object of the invention is a luggage case system comprising a case and an opening cover, each of which comprises a parallelepiped frame formed by a set of rigid panels, one of which forms a bottom and four of which form side walls, each parallelepiped frame having an opening defined by the absence of a rigid panel facing the bottom, the side walls being parallel in pairs and being orthogonal when they are adjacent, the rigid panels engaging in grooves provided in corner pieces, the corner pieces being assembled by means of assembly members, each of which has three legs, each of which comprises a fastening member engaged with a complementary fastening member belonging to the end of each corner piece, in order to fix the three corner pieces to the assembly members so as to form the right-angle vertices of the corresponding parallelepiped frame, the corner pieces defining The edge of the parallelepiped frame of a box or an opening cover, the opening of the parallelepiped frame of the box is intended to be closed by the opening cover that can be pivotally mounted on the box, the opening of the box is opposite to the opening of the opening cover, at least one edge of the parallelepiped frame of the box and / or the opening cover is covered from the outside by at least one corresponding edge of the rigid panel assembled to either side of the corner piece corresponding to the edge by mechanical fastening means, the mechanical fastening means being configured to connect at least one edge to the rigid panels on either side of the corner piece by passing through the rigid panel, and the mechanical fastening means does not pass through the corner piece or the assembly member, at least one edge ensuring the connection between adjacent and orthogonal rigid panels on both sides of the corresponding corner piece, and the rigid panels are thus engaged in the corner piece without being fixed to the corner piece.

[0009] The luggage system according to the invention has the obvious advantages of being flexible and very strong, since the solid edging provides protection for the edges, increasing the rigidity of the luggage structure, while being, for example, directly sewn or nailed or riveted into the panels on either side of the corner pieces, but not into the corner pieces themselves, nor into the assembly members or “connectors” connecting the different corner pieces at each vertex of the parallelepiped structure of the luggage system.

[0010] Thus, there is flexibility, in other words a degree of freedom, at each interface between corner pieces and panels, thereby ensuring appropriate flexibility of the structure (flexibility also ensured by the choice of the panels themselves).

[0011] Advantageously, the mechanical fastening means comprises a stitch which passes through the rigid panels on both sides of the corner piece and which does not pass through the corner piece or the assembly member.

[0012] According to one embodiment, the corner piece has a groove with an L-shaped cross-section and the rigid panel has a folded portion on at least a portion of its edge, in particular at right angles towards the inside of the corresponding parallelepiped frame, so as to form a peripheral edge with at least a portion of the L-shaped cross-section, the peripheral edge of the rigid panel engaging in the groove arranged in line with the corner piece, so as to ensure that the rigid panel is engaged on the corner piece.

[0013] According to one embodiment, the corner piece is fixed to the assembly member by means of fastening screws.

[0014] Advantageously, the luggage case system comprises a reinforcement frame attached to the case at the opening of the parallelepiped frame of the case and / or at the opening of the parallelepiped frame of the opening cover.

[0015] In particular, the reinforcement frame may be made of carbon fibers.

[0016] According to one embodiment, at least one of the following accessory components is attached to the reinforcement frame: one or more grab handles, one or more locks, one or more hinges, a lining, one or more fasteners, one or more hasps.

[0017] According to one embodiment, the luggage system comprises a strip of a parallelepiped frame of the case with a peripheral edge on the opening side, the strip protruding, the protrusion being configured to guide the opening cover during closing and to help increase the rigidity between the case and the opening cover when the luggage system is in use.

[0018] Advantageously, the luggage system further comprises removable corner wraps to protect the vertices of each parallelepiped frame.

[0019] The invention also relates to a method for manufacturing a luggage system as briefly described above, according to which, for each parallelepiped frame:

[0020] Cutting rigid panels,

[0021] folding a portion of the peripheral edge of the rigid panel at a right angle so as to form a peripheral edge of the rigid panel having at least a portion thereof being L-shaped in cross-section,

[0022] The peripheral edge of each rigid panel is engaged in a groove having an L-shaped cross section arranged on the corner piece,

[0023] The corner pieces in which the rigid panels are joined are assembled to the assembly members to form each parallelepiped frame, and then

[0024] The rigid panels belonging to each parallelepiped frame are wrapped with fabric from the outside,

[0025] Set the hemming on each edge of each parallelepiped frame,

[0026] implanting mechanical fastening means to secure each edge to two adjacent rigid panels, the mechanical fastening means being implanted on each side of the corresponding corner piece, the mechanical fastening means passing through and penetrating the edge and the corresponding rigid panel, and the mechanical fastening means not passing through any of the corner pieces or the corresponding assembly members,

[0027] In this way, a box is formed on the one hand and an opening cover is formed on the other hand.

[0028] Assemble the box body and the opening cover, which is pivotally mounted on the box body.

[0029] According to the invention, the fabric may be made of leather or any other suitable facing material.

[0030] According to one embodiment, the mechanical fastening means comprises sutures.

[0031] According to an advantageous embodiment, the rigid panel is marked to facilitate folding of at least a portion of its peripheral edge.

[0032] According to one embodiment, the reinforcement frame is also attached to the parallelepiped frame of the box and / or to the parallelepiped frame of the opening cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention relates to a luggage case system and a corresponding method of manufacturing. Figures 1 to 3 An example of a luggage case system 1 according to the invention is shown in an isometric view, a top view and a side view, respectively.

[0050] like[ Figure 2 ]or[ Figure 3 ], such a luggage system 1 may sometimes also be referred to as a "trolley" type luggage, i.e., it includes casters 4 and a telescopic handle 6 for rolling on the ground. The luggage system includes a box body 110 and an opening cover 120. The opening cover 120 is pivotally mounted to the box body 110, for example, by a hinge 9.

[0051] like[ Figure 4 ], the box 110 is formed by an assembly of corner pieces 2. The corner pieces 2 are assembled to form a parallelepiped frame. Figure 5] as shown, five rigid panels 11 are engaged in grooves 21 arranged in the corner pieces 2, thereby forming such a parallelepiped frame. Generally speaking, the rigid panels 11 are preferably made of a material suitable for the intended use, and are therefore selected because of their strength and lightness, as well as compatibility with the method of attaching the edging to the rigid panels (in particular sewing), as described in detail below. In particular, the rigid panels 11 can be made of a self-reinforced thermoplastic series of materials, such as srPET ("self-reinforced polyethylene terephthalate"), srPLA ("self-reinforced polylactic acid"), etc. The rigid panels can, for example, be made of srPP ("self-reinforced polypropylene"). The parallelepiped frame of the box body 110 has an upper opening designed to be closed by an opening cover 120, which itself is configured to be, for example, pivotally mounted on the box body 110.

[0052] Reference [ Figure 6 ], the corner pieces 2 of the parallelepiped frame of the box body 110 are connected by an assembly member 3. The assembly member 3 is a connecting element with three axes, called a tripod.

[0053] Preferably, the groove 21 arranged in the corner piece 2 has an L-shaped cross section and the rigid panel 11 has a fold 12 along all or part of its peripheral edge. To this end, for example, a weakening is created by digging a groove in the material of the rigid panel 11 so as to reduce the thickness of the rigid panel 11 along an axis parallel to the edge, for example at a distance between 2 mm and 6 mm from the edge. This local weakening makes it easier to fold the rigid panel 11. A rigid panel 11 is thus obtained, at least part of its peripheral edge having a fold 12 and therefore having an L-shaped cross section.

[0054] Reference [ Figure 7 ], which shows a cross-sectional view of the vertices of the parallelepiped frame of the luggage system 1, a fabric 90 can be installed from the outside around the perimeter of the frame formed by assembling the corner pieces 2 and the rigid panels 11 attached together via assembly members 3. The fabric 90 is used to wrap the panels 11. The fabric 90 can be made of leather or another facing material. For example, the fabric 90 can be a metal strip, a film exterior or any other material suitable for the purpose of facing and covering the luggage.

[0055] Still refer to [ Figure 7 ], the edging 50 is placed on the edge of the parallelepiped frame, outside the volume defined by the frame, so as to protect the edges of the luggage system 1.

[0056] Also refer to [ Figure 7], according to the present invention, the hem 50 is assembled to the rigid panel 11 by installing a mechanical fastening device that can pass through (in other words, perforate) the hem 50 and the rigid panel 11 so as to attach the hem 50 to the rigid panel 11. The mechanical fastening device can be, for example, a nail or a rivet, a combination of the two, or any other similar device. In the embodiment described in more detail below, the mechanical fastening device includes a suture, i.e., a stitching line.

[0057] like[ Fig.12 ], the stitching 51 thus passes through each hem 50 and each rigid panel 11 of the box 110. The stitching 51 passes neither through the corner piece 2 nor through the assembly member 3 of the box 110. If the fastening means are nails or rivets or any other similar means, the same applies: the fastening means passes through the hem 50 and the corresponding rigid panel 11 on both sides of the corner piece 2, without passing through the corner piece 2 or the fastening member 3.

[0058] The opening cover 120 is also formed by an assembly of corner pieces 2, in which the rigid panels 11 are joined by translation, and the corner pieces 2 are connected by [ Fig. 9 ] are attached together with the assembly members 3 shown in FIG. The binding 50 is arranged on the edge of the opening cover 120 and is mechanically attached (e.g., sewn, in other words, sewn) to the rigid panel 11, and the seam 51 does not pass through the corner piece 2 or the assembly member 3 of the cover 120. The stitches 51 pass through each binding 50 and each rigid panel 11 of the opening cover 120.

[0059] A method for manufacturing the luggage system 1 according to one embodiment is described below.

[0060] Manufacturing method

[0061] The rigid panel 11 is, for example, a panel of a self-reinforced thermoplastic material (such as srPLA, srPET or srPP), cut from a semi-processed or consolidated sheet of the selected self-reinforced thermoplastic material, for example comprising a plurality of folds, in particular, for example, seven folds. Figure 8 ] can be obtained by laser cutting or by any other suitable method.

[0062] The weakened portion to facilitate folding can also be produced, for example, by partial cutting in thickness, in particular by laser cutting technology or by another suitable technology. The rigid panel 11 is particularly preferably cut in this way a few millimeters from the edge, for example 3 mm from the edge, to cut part of its thickness, for example half of its thickness, to facilitate folding.

[0063] The rigid panel 11 made of self-reinforced thermoplastic material is cut to the same size as each face of the outer shell of the luggage system 1 , which corresponds to the parallelepiped structure of the luggage system 1 and has two parts, one for the box 110 and the other for the lid 120 .

[0064] The cut, for example made by laser cutting, forms a groove, ie a “weak part”, for example about 3 mm from the edge at mid-thickness of the rigid panel 11 .

[0065] Reference [ Fig.10 ]as well as[ Figure 7 ], the folded portion 12 of the rigid panel 11 is then engaged in one or more grooves 21 provided in each corner piece 2.

[0066] According to one embodiment of the proposed manufacturing method, the rigid panel 11 is firstly decorated, in other words covered and wrapped, by wrapping it from the outside with a fabric 90 (made of leather or any other finishing material suitable for this purpose, as previously shown).

[0067] The corner piece 2 is assembled to an assembling member 3 attached thereto by means of, for example, screw connection. The assembling member 3 is used to join and attach the corner piece 2 together in three directions to form a three-dimensional right angle.

[0068] like[ Figure 8 ] As shown in FIG. 1 , in order to produce a parallelepiped frame of a box 120 for the luggage system 1, multiple sets of corner pieces 2 and rigid panels 11 are assembled to form a rectangular parallelepiped, wherein one rigid panel 11 forms the bottom of the box 110, and four rigid panels 11 form the side walls of the box 110, and the box 110 is open along its last face. The opening of the box 110 is configured to be closed via an opening cover 120 manufactured in a similar manner to the box 110.

[0069] Thus, the three panels are assembled by engaging them in corresponding grooves in the corner piece 2, and the three corresponding ends of the corner piece 2 are attached to an assembling member 3, which may be a connector made of plastic or other suitable material, in particular as [ Fig. 9 ] is a "triangle" shown in FIG. The assembly member 3 is used to connect three corner pieces 2. Three rigid panels 11 with folded edges 12 are joined in each corner piece 2, thereby forming a parallelepiped frame of the box 110. The parallelepiped frame of the opening cover 120 is manufactured in a similar manner.

[0070] The assembly member 3 (also called a tripod) engages into three corner pieces 2 forming a three-dimensional right angle to connect them together. The corner pieces 2 are then attached to the tripod by screwing or by any other suitable assembly means, such as by screws and inserts.

[0071] One advantage of the present invention is that by assembling a flat rigid panel 11 (except for its right-angled folded peripheral edge (folded portion 12)) via a corner piece 2 and an assembly member 3 (or tripod), a rectangular parallelepiped is formed without the need for a draft angle required when using thermoforming and / or plastic injection or hot pressing techniques.

[0072] In contrast to luggage piece shells manufactured by thermoforming and / or hot pressing and / or any other forming method, including those luggage piece shells made of self-reinforced thermoplastic materials, the faces of the frame of the box body 110 (like those of the opening cover 120) are planar and regular in this document, without concave or convex parts.

[0073] As a manufacturing method, it should also be noted that according to the present invention, this technology of assembling the rigid panel 11 assembled by the corner pieces 2 and the tripod-type assembly components 3 (or other equivalent assembly components) also makes it easy to change the corresponding volumes of the box body 110 and the opening cover 120 of the luggage system 1.

[0074] The fabric 90 (made of leather or any other facing material suitable for the purpose, as previously shown) is arranged to provide an outer sheathing for the rigid panel 11 of the frame of the box 110. The same applies to the opening cover 120.

[0075] The next step is to provide hemming 50, such as [ Fig.11 ] as shown in order to protect the edge of the frame of the case 110. The same applies to the opening cover 120. As is well known in the technical field of luggage systems, the edging 50 constitutes a fastener in the form of a right-angle piece attached to the outside of the case 110 or the opening cover 120. The edging is therefore an elongated part with a V-shaped cross-section, which is made of a flexible, durable material and is configured to cover the edge of the luggage system 1 at the junction between the two rigid panels 11. The edging 50 thus protects the edge of the luggage system 1. The edging 50 is made, for example, of leather or lozine (a soft, strong material made of vulcanized paper) or any other material with similar softness and strength properties.

[0076] The edging 50 is provided on each edge at the joint of the two rigid panels 11 and is mechanically attached. For example, the edging 50 is sewn and sewed through the rigid panels 11 on each side of the corner piece 2 without sewing the corner piece 2 or the assembling member 3, so as to consolidate, strengthen and reinforce the frame of the box 110 composed of the corner piece 2 and the rigid panels 11, which is assembled by engaging the L-shaped edge of each rigid panel 11 in the groove 21 of the corner piece 2 and by attaching the corner pieces 2 together via the assembling member 3. The same applies to the opening cover 120.

[0077] This makes the luggage system 1 more robust.

[0078] like[ Fig.12 ], according to one embodiment, the hemming 50 is sewn to the rigid panel 11. This is achieved by passing a stitch through the hemming 50 and through the rigid panel 11. The stitch 51 passes through the rigid panel 11 (in particular made of a self-reinforced thermoplastic material) and the hemming 50 so as to sew the hemming 50 to the rigid panel 11, thereby consolidating the frame of the box 110. The same applies to the opening cover 120. This therefore protects the edge of the frame of the box 110 and conceals the assembly joint between the corner piece 2 and the rigid panel 11. The same applies to the opening cover 120.

[0079] At the same time, the luggage system 1 according to the invention remains flexible enough to absorb the mechanical stresses to which the luggage system 1 is subjected, thereby increasing its strength and durability. In fact, in embodiments particularly involving seams, the seams do not pass through the corner piece 2 or the assembly member 3. As a result, the rigid panel 11 can still slide in the groove 21 of the corner piece 2 and can only pivot around the corner piece 2 to a very limited extent. This effect can also be obtained by fixing the hem 50 to the rigid panel 11 using other mechanical fastening means, such as nails or rivets.

[0080] The faces of the resulting parallelepiped structure of the housing 110 are therefore completely parallel. The same applies to the opening cover 120 .

[0081] Therefore, the opening cover 120 is assembled in a similar manner to the box body 110. Fig.13 ], the cover frame is made of an angle piece 2 and a rigid panel 41. The angle piece 2 has a groove 21 in which the edges 42 of the rigid panel 41, for example made of a self-reinforced thermoplastic material, are respectively engaged. The angle pieces 2 are attached together by assembly members 3. The assembly members 3 include, for example, three legs 31, each of which includes a fastening member that engages with a complementary fastening member belonging to the end of each angle piece 2, so as to attach the angle piece 2 to the assembly member 3 so as to form a right angle corresponding to the vertices of the parallelepiped frame of the opening cover 120.

[0082] Then, according to one embodiment, the reinforcement means (reinforcement frame, straps) and accessories (wheels, telescopic pole, handles, locks) can be assembled, as [ Fig.14 ] as shown.

[0083] To this end, one or more reinforcement frames 81 are provided. Preferably, one of these reinforcement frames is located in the box 110 and another identical reinforcement frame is located in the opening cover 120 and extends over a rigid panel 11 attached to a vertical angle piece 2, i.e., an angle piece 2 orthogonal to the bottom of the parallelepiped frame forming the box 110 and / or the opening cover 120.

[0084] The reinforcement frame 81 can be wrapped with fabric or any other suitable finishing material, such as leather, decorative metal sheet, etc. This means that a thermoformed or non-thermoformed lining can be installed inside at least one of the parallelepiped frames, in particular inside the box 110.

[0085] According to one embodiment, the sheathed strap 82 is placed against the thermoformed liner of the case 110. As is known, the strap 82 is a strap, particularly made of metal or any other suitable rigid material, used to strap and reinforce the luggage system 1.

[0086] In the opening cover 120, in a similar manner, a liner may be installed inside the opening cover 120. A divider or any other functional accessory, such as an elastic or rigid strip, etc., may also be installed within the volume of the opening cover 120.

[0087] The reinforcement frame 81 is locked to the frame of the box 110 and / or the frame of the opening cover 120, in particular to the corner piece 2 of the corresponding parallelepiped frame. The reinforcement frame 81 is pressed against the parallelepiped frame of the box 110 and is attached to it. The same applies to the opening cover 120 if necessary.

[0088] The presence of the reinforcement frame 81 increases the robustness of the luggage system 1. Optionally, functional accessories such as locks 7, buckles (movable metal parts attached to the opening cover of a luggage piece (such as a suitcase) to enable it to be closed), hinges 9, fasteners (leather, metal or fabric straps used to keep the luggage piece open) can be attached. Threaded connections are used to lock the structure of the luggage system and attach these accessories.

[0089] The reinforcement frame 81 is preferably made of a rigid, lightweight and strong material, such as aluminum, carbon fiber, ABS, srPP or other self-reinforcing thermoplastic materials.

[0090] The strip 82 can be part of the reinforcing frame 81 or a separate part. The strip 82 protrudes relative to the edge of the rigid panel 11, surrounding the opening in the parallelepiped frame of the box 110. The protrusion formed by the strip 82 is thus orthogonal to the peripheral edge of the opening around the box 110, forming a small wall, for example 2 mm to 8 mm high, which can guide the opening cover 120 of the luggage system 1 during its closure. The strip 82 also helps to increase the rigidity between the box 110 and the opening cover 120 during the use of the product (rolling, carrying, etc.).

[0091] Therefore, for example, one reinforcement frame 81 is attached in the volume of the box body 110 , and another reinforcement frame is attached in the volume of the opening cover 120 .

[0092] According to one embodiment, the vertices of the luggage system 1 are protected by removable rigid corner wraps 15. The removable nature of the rigid corner wraps 15 protecting the vertices of the parallelepiped-shaped luggage system 1 improves the repairability of the luggage system 1 according to the invention.

[0093] According to one embodiment, the suture 51 may be stopped before reaching the apex, in particular at a distance between 10 mm and 15 mm upstream of each apex.

[0094] For example, the distance between the stitching and the edge of the binding 50 is about 2 mm.

[0095] For the leather or lozine edging 50 sewn into a suitable srPP panel, the thickness of the composite to be sewn is, for example, 0.9 mm, wherein the leather or lozine edging 50, the fabric 90 with a thickness between 0.5 mm and 1 mm, and the rigid multilayer srPP panel 11 with a thickness of about 1.2 mm, i.e., the total thickness is between 2.6 mm and 3.1 mm.
