Description

Technical Field

[0001] The present invention relates to the field of trunks, and more specifically, to a trunk that can be moved by rolling on a set of casters.

[0002] It should be noted that a trunk can be distinguished from a suitcase and other smaller travel bags. Thus, a trunk is known to be defined as a large and rigid travel bag. Specifically, a trunk is generally bulkier (taller and longer) than a suitcase, more rigid, and has a parallelepiped shape.

Background Art

[0003] The state of the art features a step of assembling a frame, for example, a frame composed of angle pieces defining a substantially parallelepiped structure in which panels are assembled to form a barrel, and a lid enabling the opening and closing of a travel bag, including an explanation of a travel bag and a method of manufacturing such a travel bag.

[0004] European Patent Application Publication No. 3476241 (A1) describes such an assembly method for this type of travel bag. However, this type of travel bag is not a trunk and does not have an equivalent structure.

[0005] Furthermore, there is a need for larger travel bags, in other words, trunks. Trunks are designed to be able to transport more volume and mass and are generally stronger and more durable. This means that trunks are very robust. The sides of this type of trunk extend parallel to each other, and adjacent sides form right angles. The edges of such a trunk need to be protected by sockets that reinforce these edges.

[0006] However, it is difficult to reconcile the rigidity and flexibility required for such a trunk.

[0007] The object of the present invention is to provide a trunk having both high rigidity and suitable flexibility. Therefore, the trunk according to the present invention is robust and durable. The present invention also relates to a method of manufacturing such a trunk.

Summary of the Invention

[0008] More precisely, the object of the present invention is a trunk system comprising a barrel and an opening lid, wherein the barrel and the opening lid each comprise a parallelepiped frame composed of a set of rigid panels, one of the rigid panels forming a bottom, four rigid panels forming 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 perpendicular when adjacent, the rigid panels being engaged in grooves provided in angle pieces, the angle pieces being assembled by assembly members, each assembly member having three legs, each leg having a fastening member engaging a complementary fastening member belonging to the end of each angle piece so as to fasten three angle pieces to the assembly member to form a right vertex of the corresponding parallelepiped frame, the angle pieces defining an edge of the parallelepiped frame of the barrel or the opening lid, the opening of the parallelepiped frame of the barrel being intended to be closed by an opening lid pivotally attached to the barrel, the openings of the barrel and the opening lid facing each other, at least one edge of the parallelepiped frame of the barrel and / or the opening lid being covered from the outside by at least one respective socket assembled by mechanical fastening means to the rigid panels on both sides of the angle piece corresponding to the edge, the mechanical fastening means being configured to connect at least one socket to the rigid panels on both sides of the angle piece by passing through the rigid panel, the mechanical fastening means not passing through the angle piece or the assembly member, at least one socket ensuring the joint between adjacent and perpendicular rigid panels on both sides of the corresponding angle piece, and the rigid panel being engaged with the angle piece without being fastened to the angle piece thereby, a trunk system.

[0009] The trunk system according to the present invention has a robust socket protecting the edge, improving the rigidity of the trunk structure, and at the same time, for example, being stitched or stapled or riveted directly to the panels on both sides of the angle piece. However, neither the angle piece itself nor the assembly member or "connector" connecting different angle pieces at each vertex of the parallelepiped structure of the trunk system is stitched or stapled or riveted, so it has the particular advantage of being flexible and very robust.

[0010] Therefore, there is flexibility, in other words, degrees of freedom, at each interface between the angle piece and the panel, ensuring that the structure is appropriately flexible (the flexibility is also ensured by the choice of the panel itself).

[0011] Advantageously, the mechanical fastening means includes stitching, which is performed through the rigid panels on both sides of the angle piece and does not pass through the angle piece or the assembly member.

[0012] According to one embodiment, the angle piece has a groove with an L-shaped cross-section, and the rigid panel has a fold at at least a part of the edge of the rigid panel, specifically at a right angle, so as to form a peripheral part having an L-shaped cross-section at least in part, and the peripheral part of the rigid panel engages with a groove provided to fit the angle piece so as to ensure the engagement of the rigid panel with the angle piece.

[0013] According to one embodiment, the angle piece is fastened to the assembly member by fastening screws.

[0014] Advantageously, the trunk system includes a reinforcing frame attached to the barrel at the opening of the parallelepiped frame of the barrel and / or the parallelepiped frame of the opening lid.

[0015] Specifically, the reinforcing frame can be made of carbon fiber.

[0016] According to one embodiment, at least one of the accessories, which are one or more handles, one or more locks, one or more hinges, an inner lining, one or more fasteners, and one or more latches, is attached to the reinforcement frame.

[0017] According to one embodiment, the trunk system includes a strap that surrounds the parallelepiped frame of the barrel at the peripheral edge on the opening side, the strap protrudes, and the protruding portion is configured to guide the opening lid when closing the opening lid and contribute to the rigidity between the barrel and the opening lid during the use of the trunk system.

[0018] Advantageously, the trunk system also includes removable corners for protecting the vertices of each parallelepiped frame.

[0019] The present invention also relates to a method of manufacturing a trunk system as briefly described above, according to which, for each parallelepiped frame, a rigid panel is cut, a part of the peripheral edge of the rigid panel is bent at a right angle so as to form the peripheral edge of the rigid panel having at least a part with an L-shaped cross-section, the peripheral edge of each rigid panel is engaged with a groove provided in the angle piece with an L-shaped cross-section, the angle piece with the rigid panel engaged is assembled on the assembly member to form each parallelepiped frame, and then, the rigid panels belonging to each parallelepiped frame are covered with fabric from the outside, sockets are provided at each edge of each parallelepiped frame, mechanical fastening means are embedded to fasten each socket to two adjacent rigid panels, the mechanical fastening means are embedded on each side of the corresponding angle piece, the mechanical fastening means are drilled through the socket and the corresponding rigid panel, and the mechanical fastening means do not pass through either the angle piece or the corresponding assembly member, forming the barrel on one hand and the opening lid on the other hand, The barrel and the opening lid are assembled, and the opening lid is pivotally attached to the barrel.

[0020] According to the present invention, the fabric can be made of leather or any other suitable exterior material.

[0021] According to one embodiment, the mechanical fastening means consists of stitching.

[0022] According to an advantageous embodiment, the rigid panel is marked to facilitate the bending of at least a part of the peripheral edge of the rigid panel.

[0023] According to one embodiment, the reinforcing frame is also attached to the parallelepiped frame of the barrel and / or the parallelepiped frame of the opening lid.

Embodiments for Carrying Out the Invention

[0027] The present invention relates to a trunk system and a corresponding manufacturing method. Figures 1 - 3 show an example of a trunk system 1 according to the present invention in an isometric view, a top view, and a side view, respectively.

[0028] As seen in Figure 2 or Figure 3, such a trunk system 1 may be called a "trolley" - type trunk, that is, it includes caster wheels 4 for rolling on the floor and a telescopic rod handle 6. The trunk system includes a barrel 110 and an opening lid 120. The opening lid 120 is pivotally attached to the barrel 110 by, for example, a hinge 9.

[0029] The barrel 110 is formed from the assembly of the angle pieces 2 as seen in FIG. 4. The angle pieces 2 are assembled to form a parallelepiped frame. Five rigid panels 11 engage with the grooves 21 arranged in the angle pieces 2 so as to form such a parallelepiped frame as shown in FIG. 5. Generally, the rigid panels 11 are preferably made of a material suitable for the intended use, and as a result, their strength and light weight, as well as the method of attaching the socket to the rigid panel, which will be described in detail below, specifically the compatibility with stitching, are selected. Specifically, the rigid panels 11 can be made of materials from the group of self-reinforcing thermoplastic plastics such as srPET (representing "self-reinforced polyethylene terephthalate"), srPLA (representing "self-reinforced polylactic acid"). The rigid panel can be made of, for example, srPP ("self-reinforced polypropylene"). The parallelepiped frame of the barrel 110 has an upper opening designed to be closed by an opening lid 120 configured to be pivotally attached, for example, onto the barrel 110 itself.

[0030] Referring to FIG. 6, the angle pieces 2 of the parallelepiped frame of the barrel 110 are connected to each other by assembly members 3. The assembly members 3 are connecting elements having three axes called tripod legs.

[0031] Preferably, the grooves 21 arranged in the angle pieces 2 have an L-shaped cross-section, and the rigid panels 11 have folds 12 along all or part of their peripheral edges. For this purpose, for example, 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 of 2 mm to 6 mm from the edge, a weakened part is formed. This local weakened part makes it easier to fold the rigid panel 11. In this way, a rigid panel 11 is obtained in which at least part of the peripheral edge has a fold 12 and thus has an L-shaped cross-section.

[0032] Referring to FIG. 7 showing a cross-sectional view of the vertices of the parallelepiped frame of the trunk system 1, by assembling the angle piece 2 and the rigid panel 11 attached to each other by the assembly member 3, a fabric 90 can be attached to the outer periphery of the frame thus formed from the outside. The fabric 90 is used to cover the panel 11. The fabric 90 can be made of leather or another exterior material. For example, the fabric 90 can be a metal strip, a film appearance, or any other material suitable for the purpose of exterior and covering of the trunk.

[0033] Referring further to FIG. 7, the socket 50 is disposed on the edge of the parallelepiped frame from the outside of the volume defined by the frame to protect the edge of the trunk system 1.

[0034] Referring also to FIG. 7, according to the present invention, the socket 50 is assembled to the rigid panel 11 by installing mechanical fastening means that can pass through, in other words, pierce the socket 50 and the rigid panel 11 to attach the socket 50 to the rigid panel 11. The mechanical fastening means may be, for example, nails or rivets, a combination of both, or any other similar means. In the embodiment described in more detail below, the mechanical fastening means consists of stitching, in other words, seams.

[0035] As seen in FIG. 12, the stitching 51 thus passes through each rigid panel 11 of each socket 50 and barrel 110. The stitching 51 does not pass through either the angle piece 2 of the barrel 110 or the assembly member 3. The same applies when the fastening means is a nail or rivet or any other similar means. The fastening means passes through the socket 50 and each respective rigid panel 11 on both sides of the angle piece 2 without passing through either the angle piece 2 or the fastening member 3.

[0036] Also, the access lid 120 is also formed from the assembly of angle pieces 2 with which the rigid panel 11 is engaged by translation, and the angle pieces 2 are attached to each other via the assembly members 3 as seen in FIG. 9. The sockets 50 are arranged at the edges of the access lid 120 and are mechanically attached to the rigid panel 11, for example stitched, or rather sewn, and the stitching 51 does not pass through either the angle pieces 2 or the assembly members 3 of the lid 120. The stitching 51 is performed through each socket 50 of the access lid 120 and each rigid panel 11.

[0037] Hereinafter, a manufacturing method of the trunk system 1 according to an embodiment will be described.

[0038] Manufacturing method

[0039] The rigid panel 11 is a panel of a self-reinforced thermoplastic material such as, for example, srPLA, srPET or srPP, and is cut from a semi-processed or consolidated sheet of the selected self-reinforced thermoplastic material, for example, including a plurality of folds, specifically, for example, seven folds. These rigid panels 11 shown particularly in FIG. 8 can be obtained by laser cutting or any other suitable method.

[0040] The weakened portions for facilitating bending can also be produced, for example, by partial cutting of the thickness, specifically by laser cutting technology, or by another suitable technology. The rigid panel 11 is particularly preferably cut in this way over a few millimeters from the edge, for example 3 mm from the edge, and over a part of the thickness of the rigid panel 11, for example half of the thickness of the rigid panel 11, in order to facilitate bending.

[0041] The rigid panel 11 of the self-reinforced thermoplastic material is cut to the size of each face of the shell of the trunk system 1, and the shell has two parts corresponding to the parallelepiped structure of the trunk system 1, one for the barrel 110 and the other for the lid 120.

[0042] For example, a cut created by laser cutting forms a groove, i.e., a "weak part", about 3 mm from the edge in the central part of the thickness of the rigid panel 11.

[0043] Referring to FIGS. 10 and 7, the fold(s) 12 of the rigid panel 11 are then engaged with one or more grooves 21 provided in each angle piece 2.

[0044] According to one embodiment of the proposed manufacturing method, the rigid panel is first finished with a fabric 90 that covers the rigid panel 11 from the outside (made of leather or any other suitable exterior material for this purpose as shown previously), in other words, covered and coated.

[0045] The angle piece 2 is assembled, for example, by screwing onto the assembly member 3 to which the angle piece 2 is attached. The assembly member 3 is used to join and attach the angle piece 2 in three directions to form a three-dimensional right angle.

[0046] As shown in FIG. 8, to fabricate a parallelepiped frame for the barrel 120 of the trunk system 1, a set of the angle piece 2 and the rigid panel 11 is assembled such that one rigid panel 11 forms the bottom of the barrel 110 and four rigid panels 11 form a rectangular parallelepiped that forms the side walls of the barrel 110, and the barrel 110 is open along its last face. The opening of the barrel 110 is configured to be closed via an opening lid 120 manufactured in the same manner as the barrel 110.

[0047] Thus, the three panels are assembled by engaging each in a respective groove within the angle piece 2, and each of the three ends of the angle piece 2 is attached to an assembly member 3, which can be a connector made of plastic or another suitable material, specifically a "tripod" as shown in FIG. 9. The assembly member 3 is used to join the three angle pieces 2. The three rigid panels 11 with the bent edges 12 are engaged with each angle piece 2 and thus form the parallelepiped frame of the barrel 110. The parallelepiped frame of the access lid 120 is made in a similar way.

[0048] The assembly member 3, also called a tripod, engages three angle pieces 2 that form a three-dimensional right angle and connects them to each other. Next, the angle pieces 2 are attached to the tripod by screwing or by any other suitable assembly means, such as screws and inserts.

[0049] One advantage of the present invention is that a right-angled parallelepiped is formed without the draft required when using thermoforming and / or plastic injection or thermocompression bonding techniques, by assembling the rigid panels 11, which are planar (except for the peripheries bent at right angles (folds 12)), via the angle pieces 2 and the assembly member 3 (or tripod).

[0050] In contrast to travel bag shells manufactured by thermoforming and / or thermocompression bonding and / or any other forming method, including those made from self-reinforcing thermoplastic materials, the surfaces of the frame of the barrel 110, as well as those of the access lid 120, are flat and regular herein, without recesses or protrusions.

[0051] It should also be noted that this technique according to the invention of assembling the rigid panels 11 assembled by the angle pieces 2 and the tripod-shaped assembly member 3 (or other equivalent assembly members) also facilitates varying the respective volumes of the barrel 110 and the access lid 120 of the trunk system 1.

[0052] The cloth 90 (made of leather or any other suitable outer material for this purpose, as shown previously) is arranged to provide an outer covering for the rigid panel 11 of the frame of the barrel 110. The same applies to the opening lid 120.

[0053] The next step is to provide a socket 50, as shown in FIG. 11, to protect the edges of the frame of the barrel 110. The same applies to the opening lid 120. As is well known in the technical field of trunk systems, the socket 50 constitutes an assembly in the form of a right-angled part attached to the outside of the barrel 110 or the opening lid 120. Thus, the socket is an elongated part having a V-shaped cross-section, made of a flexible resistant material, and configured to cover the edges of the trunk system 1 at the junction between the two rigid panels 11. Thus, the socket 50 protects the edges of the trunk system 1. The socket 50 is made of, for example, leather or lozine (a flexible and strong material made from vulcanized paper), or any other material having similar flexibility and strength characteristics.

[0054] The socket 50 is provided at each edge of the junction of the two rigid panels 11 and is mechanically attached. For example, the socket 50 is assembled by engaging the L-shaped edges of each rigid panel 11 in the groove 21 of the angle piece 2 and attaching the angle pieces 2 to each other via the assembly member 3. To strengthen, reinforce, and rigidify the frame of the barrel 110 composed of the angle piece 2 and the rigid panel 11, the rigid panel 11 is stitched and sewn through on each side of the angle piece 2 without stitching the angle piece 2 or the assembly member 3. The same applies to the opening lid 120.

[0055] This improves the robustness of the trunk system 1.

[0056] As shown in FIG. 12, according to one embodiment, the socket 50 is stitched to the rigid panel 11. This is achieved by stitching through the socket 50 and the rigid panel 11. The stitching 51 passing through the rigid panel 11 and the socket 50, specifically the rigid panel 11 made of a self-reinforcing thermoplastic material, for sewing the socket 50 to the rigid panel 11 strengthens the frame of the barrel 110. The same applies to the access cover 120. Thus, this protects the edge of the frame of the barrel 110 and hides the assembly joint between the angle piece 2 and the rigid panel 11. The same applies to the access cover 120.

[0057] At the same time, the trunk system 1 according to the present invention retains a flexibility suitable for absorbing mechanical stresses received by the trunk system 1, thereby improving its strength and durability. In fact, especially in embodiments including stitching, the sewing thread does not pass through the angle piece 2 or the assembly member 3. Thereby, the rigid panel 11 can still slide within the groove 21 of the angle piece 2 and can pivot only within a very limited range around the angle piece 2. This effect can also be obtained by using other mechanical fastening means such as nails or rivets to fasten the socket 50 to the rigid panel 11.

[0058] Therefore, the faces of the resulting parallelepiped structure of the barrel 110 are completely parallel. The same applies to the access cover 120.

[0059] In this way, the access cover 120 is assembled in the same manner as the barrel 110. The frame of the cover is made of an angle piece 2 and a rigid panel 41 as shown in FIG. 13. The angle piece 2 is characterized by grooves 21 in which the edges 42 of the rigid panel 41, made of, for example, a self-reinforcing thermoplastic material, are respectively engaged. The angle pieces 2 are attached to each other by the assembly members 3. The assembly member 3 includes, for example, three legs 31, and each leg 31 has 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 to form a right angle corresponding to the vertex of the parallelepiped frame of the access cover 120.

[0060] Next, according to one embodiment, as shown in FIG. 14, the reinforcing means (reinforcing frame, strap) and accessories (wheel, telescopic rod, handle, lock) can be assembled.

[0061] For this purpose, one or more reinforcing frames 81 are provided. Preferably, one of the reinforcing frames 81 is within the barrel 110 and another identical one is within the opening lid 120 attached to the vertical angle piece 2, that is, the angle piece 2 extends orthogonally to the rigid panel 11 forming the bottom of the parallelepiped frame of the barrel 110 and / or the opening lid 120.

[0062] The reinforcing frame(s) 81 can be covered with a fabric or any other suitable exterior material, such as leather, decorative sheet metal, etc. This means that a thermoformed or non-thermoformed lining can be installed inside at least one of the parallelepiped frames, specifically inside the barrel 110.

[0063] According to one embodiment, the covered strap 82 is arranged against the thermoformed lining of the barrel 110. As is well known, the strap 82 is particularly a band of metal or any other suitable rigid material and is used to tie and reinforce the trunk system 1.

[0064] Similarly, in the opening lid 120, a lining can be installed inside the opening lid 120. Also, a separator can be installed within the volume of the opening lid 120, or any other functional accessory, such as an elastic strap or a rigid strap, etc., can be installed.

[0065] The reinforcing frame(s) 81 is / are locked to the angle piece 2 of the parallelepiped frame of the barrel 110 and / or the frame of the opening lid 120, specifically. The reinforcing frame 81 is pressed against the parallelepiped frame of the barrel 110, and the reinforcing frame 81 is attached to the frame. If necessary, the same applies to the opening lid 120.

[0066] Due to the presence of the reinforcing frame 81, the robustness of the trunk system 1 is improved. Optionally, functional accessories such as the lock 7, the catch (a movable metal part attached so as to be able to close the opening lid of a travel bag such as a trunk), the hinge 9, the fastener (a leather, metal or fabric strip used to keep the travel bag open) can be attached. Screwing is used to lock the structure of the trunk system and attach these accessories.

[0067] The reinforcing frame 81 is preferably made of a rigid, lightweight and strong material such as aluminum, carbon fiber, ABS, srPP, or another self-reinforcing thermoplastic material.

[0068] The strap 82 may be part of the reinforcing frame 81 or a separate part. The strap 82 protrudes with respect to the edge of the rigid panel 11 and surrounds the opening of the parallelepiped frame of the barrel 110. Therefore, the protrusion formed by the strap 82 is orthogonal to the peripheral edge extending around the opening of the barrel 110, forms a small wall with a height of, for example, 2 to 8 mm, and can guide when closing the opening lid 120 of the trunk system 1. The strap 82 also contributes to the rigidity between the barrel 110 and the opening lid 120 during the use of the product (rolling, carrying, etc.).

[0069] Therefore, one reinforcing frame 81 is, for example, installed within the volume of the barrel 110, and another reinforcing frame is installed within the volume of the opening lid 120.

[0070] According to one embodiment, the vertices of the trunk system 1 are protected by removable rigid corners 15. The removability of the rigid corners 15 that protect the vertices of the parallelepiped-shaped trunk system 1 improves the reparability of the trunk system 1 according to the present invention.

[0071] According to one embodiment, the stitching 51 may stop in front of the vertex, specifically at a distance of 10 mm to 15 mm upstream of each vertex.

[0072] For example, the stitching is performed at a position about 2 mm from the edge of the socket 50.

[0073] In the case of leather or lozine sockets 50 stitched to a suitable srPP panel, the thickness of the composite material to be stitched is, for leather or lozine sockets 50, for example 0.9 mm, a fabric 90 with a thickness of 0.5 mm to 1 mm, and a rigid multi-layer srPP panel 11 with a thickness of about 1.2 mm, that is, a total thickness of 2.6 mm to 3.1 mm.
