Description

Trunk system and assembly process

The present invention relates to the field of trunks, in particular movable by rolling by means of a set of casters.

It should be noted that trunks are distinct from suitcases and other luggage of smaller volume. It is thus known that trunks are defined as large rigid luggage. In particular, trunks are generally more voluminous (taller and longer) and more rigid than suitcases and have a parallelepiped shape.

STATE OF THE ART

The state of the art includes the description of luggage and methods of manufacturing such luggage which present a step of assembling a framework, for example a framework composed of angles which define a substantially parallelepiped structure on which are then assembled panels, to form a barrel, and a lid allowing the luggage to be opened and closed.

Document EP3476241A1 describes such a method of assembling this type of luggage. However, this type of luggage is not a trunk and does not have a comparable structure.

However, there is a need for larger luggage, in other words trunks. Trunks allow for more volume and mass to be carried and are generally designed to be stronger and more durable. This implies that the trunks have significant robustness. The faces of this type of trunk are parallel in pairs, with adjacent faces forming right angles. The edges of such trunks must be protected by sockets which ensure the reinforcement of these edges.

However, it is difficult to ensure both the rigidity and flexibility necessary for such trunks.

The invention aims to provide trunks having both high rigidity and suitable flexibility. The trunks according to the invention are thus robust and durable. The invention also relates to a method of manufacturing such trunks.

PRESENTATION OF THE INVENTION

More precisely, the subject of the invention is a trunk system comprising a barrel and an opening lid, the barrel and the opening lid each comprising a parallelepiped frame composed of a set of rigid panels, including a rigid panel forming a bottom and four rigid panels forming side walls, each parallelepiped frame having an opening defined by the absence of rigid panel facing the bottom, the side walls being parallel in pairs and being orthogonal when adjacent, the rigid panels being engaged in grooves provided in angles, the angles being assembled via assembly members, each assembly member having three feet, each foot comprising a fixing member cooperating with a complementary fixing member belonging to each end of the angle, so as to fix three angles to an assembly member to form a right angle vertex of the corresponding parallelepiped framework, the angles defining edges of the parallelepiped framework of the barrel or the opening cover, the opening of the parallelepiped frame of the barrel being intended to be closed by the opening cover pivotally mounted on the barrel, the openings of the barrel and of the opening cover being placed opposite each other, at least one edge of the parallelepiped frame of the barrel barrel and/or the opening cover being covered from the outside by at least one respective socket assembled by means of mechanical means of fixing to the rigid panels on either side of the angle corresponding to the edge, the mechanical means fixing devices being configured to connect, by crossing them, the at least one socket to the rigid panels on either side of the angle, and the mechanical fixing means not passing through the angles or the assembly members, the at least one socket ensuring a joint between adjacent and orthogonal rigid panels on either side of the corresponding angle, and said rigid panels thus being engaged in the angles without being fixed to them.

The trunk systems according to the invention have in particular the advantage of having both suitable flexibility and great robustness because the solid sockets ensure the protection of the edges, improving the rigidity of the structure of the trunk, while being stitched or nailed or riveted, for example, directly in the panels, on each side of the angle, but not in the angle itself nor in the assembly members or "connectors" which ensure the connection between the different angles at the level of each vertex of the parallelepiped structure of the trunk system.

There is thus flexibility, in other words a degree of freedom, at each interface between an angle and a panel, ensuring the structure has adequate flexibility (flexibility is also ensured by the choice of the panels themselves).

Advantageously, the mechanical fixing means include a stitching, the stitching being carried out through the rigid panels on either side of the angle and the stitching not passing through the angles or the assembly members.

According to one embodiment, the angles have grooves having an L-shaped section and the rigid panels have a fold over at least a portion of their edges, in particular at right angles, towards the interior of the corresponding parallelepiped framework, so as to form a peripheral edge having at least one portion having an L-shaped section, the peripheral edges of the rigid panels being engaged in the corresponding grooves provided in the angles, so as to ensure engagement of the rigid panels on the angles.

According to one embodiment, the angles are fixed to the assembly members via fixing screws.

Advantageously, the trunk system comprises a reinforcing frame fixed to the barrel at the level of the opening of the parallelepiped frame of the barrel and/or the parallelepiped frame of the opening lid.

In particular, the reinforcing frame can be made of carbon fiber.

According to one embodiment, at least one accessory part from: one or more grip handles, one or more locking locks, one or more hinges, an interior lining, one or more fasteners, one or more hasps, is fixed to the frame reinforcement.

According to one embodiment, the trunk system comprises a strip encircling the parallelepiped frame of the barrel at the level of a peripheral edge on the side of the opening, the strip projecting, the projection being configured to guide the opening cover when its closure and to contribute to the rigidity between the barrel and the opening lid when using the trunk system.

Advantageously, the trunk system also includes removable corners to protect the tops of each parallelepiped frame.

The present invention also relates to a method of manufacturing a trunk system as briefly described above, according to which, for each parallelepiped frame:

we cut rigid panels,

we make folds at right angles of portions of the peripheral edge of the rigid panels, so as to form a peripheral edge of the rigid panels having at least one portion having an L-shaped section,

the peripheral edge of each rigid panel is engaged in grooves having an L-shaped section arranged on angles,

the angles in which the rigid panels are engaged are assembled on assembly members to form each parallelepiped frame, then,

a canvas is placed to sheathe the rigid panels belonging to each parallelepiped frame from the outside,

we have sockets on each edge of each parallelepiped frame,

mechanical fixing means are installed to fix each socket to two adjacent rigid panels, the mechanical fixing means being installed on each side of the corresponding angle, the mechanical fixing means passing through, by perforating them, the socket and the rigid panel corresponding and the mechanical fixing means not passing through the angle or any of the corresponding assembly members,

so as to form the barrel on the one hand and the opening lid on the other hand,

the barrel and the opening lid are assembled, the opening lid being pivotally mounted on the barrel.

According to the invention, the canvas can be made of leather or any other suitable facing material.

According to one embodiment, the mechanical fixing means consist of a tapping.

According to an advantageous mode of implementation, rigid panels are marked to facilitate the folding of at least a portion of their peripheral edge.

According to one mode of implementation, a reinforcing frame is also fixed to the parallelepiped frame of the barrel and/or to the parallelepiped frame of the opening cover.

DETAILED DESCRIPTION OF THE INVENTION

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

As can be seen on the or the , such a trunk system 1 can sometimes be referred to as a “trolley” type trunk, that is to say comprising casters 4 and a telescopic handle-cane 6 to be moved while rolling on the ground. The trunk system comprises a barrel 110 and an opening lid 120. The opening lid 120 is for example pivotally mounted on the barrel 110, via hinges 9.

The barrel 110 is formed from an assembly of angles 2 visible on the . The angles 2 are assembled to form a parallelepiped framework. Five rigid panels 11, as shown in the , are engaged in grooves 21 arranged in the angles 2 so as to form such a parallelepiped framework. Generally speaking, the rigid panels 11 are preferably composed of a material adapted to the intended use, and therefore chosen for its properties of strength and lightness, and compatibility with the method of fixing the sockets to the rigid panels. , in particular stitching, described in detail below. In particular, the rigid panels 11 may be composed of a material from the family of self-reinforced thermoplastics, such as srPET (for “self-reinforced polyethylene terephthalate”), srPLA (for “self-reinforced polylactic acid”), etc. Rigid panels could, for example, be made of srPP (for “self-reinforced polypropylene”). The parallelepiped frame of the barrel 110 has an upper opening intended to be closed by the opening cover 120, itself configured to be mounted, for example in a pivoting manner, on the barrel 110.

In reference to the , the angles 2 of the parallelepiped framework of the barrel 110 are connected together by assembly members 3. The assembly members 3 are connecting elements with three axes, designated tripods.

Preferably, the grooves 21 provided in the angles 2 have an L-shaped section and the rigid panels 11 have a fold 12 on all or part of their peripheral edge. To this end, for example, a weakness is created by digging a wake 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 weakness created locally allows easier folding of the rigid panel 11. We thus obtain rigid panels 11 having at least a portion of their peripheral edge having a fold 12 and therefore an L-shaped section.

In reference to the , which shows a sectional view of a top of a parallelepiped frame of the trunk system 1, a canvas 90 can be placed from the outside on the periphery of the frame thus created by the assembly of angles 2 fixed between them by means of assembly members 3, and rigid panels 11. The canvas 90 makes it possible to sheath the panels 11. The canvas 90 can be made of leather or another facing material. For example, the canvas 90 can be a metal strip, a look film, or any other material suitable for this use of facing and covering a trunk.

Still with reference to the , sockets 50 are placed on the edges of the parallelepiped framework, from outside the volume defined by said framework, to protect the edges of the trunk system 1.

Also in reference to the , according to the invention, the sockets 50 are assembled to the rigid panels 11 by installing mechanical fixing means capable of crossing, in other words perforating, the sockets 50 and the rigid panels 11 in order to ensure fixing of the sockets 50 to the rigid panels 11. Mechanical means of attachment may consist of nails or rivets, a combination of both, or any other similar means, for example. In the embodiment described in more detail below, the mechanical fixing means consist of a stitching, in other words a seam.

As can be seen on the , the connection 51 is thus produced through each socket 50 and each rigid panel 11 of the barrel 110. The connection 51 does not pass through either the angles 2, nor the assembly members 3 of the barrel 110. In the case where the fixing means are nails or rivets, or any other similar means, the same applies: the fixing means pass through the socket 50 and the respective rigid panel 11, on either side of the angle 2, without crossing either the angle 2 nor the assembly members 3.

The opening cover 120 is also formed from an assembly of angles 2 in which rigid panels 11 are engaged, by translation, the angles 2 being fixed together via assembly members 3 visible on the . Sockets 50 are arranged on the edges of the opening cover 120 and mechanically fixed, for example stitched, in other words sewn, to the rigid panels 11, the stitching 51 passing through neither the angles 2 nor the assembly members 3 of the cover 120. The connection 51 is made through each socket 50 and each rigid panel 11 of the opening cover 120

The method of manufacturing a trunk system 1 is described below, according to one embodiment.

Manufacturing process

The rigid panels 11 are for example panels of self-reinforced thermoplastic material, such as srPLA, srPET or srPP for example, cut from semi-transformed or consolidated plates of the chosen self-reinforced thermoplastic material, for example comprising a plurality of plies, in particular , for illustration purposes, seven folds. These rigid panels 11 represented in particular on the can be obtained by laser cutting or by any other suitable process.

Producing the weakness to facilitate folding can also be carried out, for example, by means of partial cutting in the thickness, in particular by means of a laser cutting technique or by means of another suitable technique. The rigid panels 11 are in particular preferably incised in this way a few millimeters from the edge, for example 3 mm from the edge, over part of their thickness, for example half their thickness, in order to facilitate folding.

The rigid panels 11 of self-reinforced thermoplastic material are cut to the size of each face of the shell of the trunk system 1, the shell corresponding to the parallelepiped structure of the trunk system 1 and having two parts, one for the barrel 110 and the other for cover 120.

Thanks to the incision, for example made by laser cutting, a furrow is created, in other words a “weakness”, for example approximately 3 mm from the edge at mid-thickness of the rigid panel 11.

In reference to the , as well as the diagram of the , we then engage the fold(s) 12 of the rigid panel 11 in one or more grooves 21 provided in each angle iron 2.

According to one embodiment of the proposed manufacturing process, the rigid panels are first dressed, in other words covered and sheathed, with canvas 90 (made of leather or any other facing material suitable for this use, as indicated previously) coming sheath the rigid panels 11 from the outside.

The angles 2 are assembled on the assembly members 3 to which they are fixed, for example by screwing. The assembly members 3 make it possible to join together and fix together the angles 2 in three directions forming a three-dimensional right angle.

As shown on the , for the production of a parallelepiped frame for a barrel 120 of the trunk system 1, the sets of angles 2 and rigid panels 11 are assembled so as to form a rectangular parallelepiped with a rigid panel 11 forming the bottom of the barrel 110 and four rigid panels 11 forming the side walls of the barrel 110, the barrel 110 being open along its last face. The opening of the barrel 110 is configured to be closed via the opening lid 120 manufactured in a similar manner to the barrel 110.

Thus, three panels are assembled by engaging them in respective grooves of angles 2 and the three respective ends of said angles 2 are fixed on an assembly member 3, which can be a plastic connector or another suitable material, in particular a “tripod” as shown on the . The assembly member 3 makes it possible to join together three angles 2. Three rigid panels 11 with folded edges 12 being engaged in each angle 2, the parallelepiped framework of the barrel 110 is thus produced. The parallelepiped framework of the barrel is thus produced in a similar manner. opening cover 120.

The assembly member 3, also designated tripod, engages in the three angles 2 forming a three-dimensional right angle to connect them together. From then on, the angles 2 are fixed on the tripods by screwing or by any other suitable assembly means, for example by means of screws and inserts.

We note that an advantage of the invention, by this assembly of rigid panels 11 planes - apart from their folded peripheral edge (folds 12) at right angles, via the angles 2 and the assembly members 3 (or tripods) , we produce a rectangular parallelepiped having right angles, without a draft angle as is necessary when using thermoforming and/or plastic injection or thermocompression technology.

The faces of the frame of the barrel 110, like those of the opening cover 120, are here flat and regular, without concave or convex portion, unlike luggage shells manufactured by thermoforming and/or thermocompression and/or any other method of obtaining by molding, including in self-reinforced thermoplastic material.

As a manufacturing process, we also note that this technique, according to the invention, of assembling rigid panels 11 assembled via angles 2 and assembly members 3 of the tripod type (or other assembly members equivalents) also makes it possible to easily vary the respective volumes of the barrel 110 and the opening lid 120 of a trunk system 1.

A canvas 90 (made of leather or any other facing material suitable for this use, as indicated previously) is arranged to provide an exterior sheathing of the rigid panels 11 of the frame of the barrel 110. The same goes for the opening cover 120.

Then, we have the sockets 50, as visible on the , to protect the edges of the frame of the barrel 110. The same goes for the opening cover 120. As is known in the technical field of trunk systems, the sockets 50 constitute consolidations in the form of fixed right-angled angles outside the barrel 110 or the opening lid 120. A socket is thus a longiform part having a V-shaped section, made of flexible and resistant material and configured to cover an edge of a trunk system 1 at the junction between two rigid panels 11. The sockets 50 thus make it possible to protect the edges of the trunk system 1. The sockets 50 are for example made of leather or lozine (which is a flexible and resistant material made from vulcanized paper) or entirely other material with similar characteristics of flexibility and resistance.

A socket 50 is placed on each edge at the junction of two rigid panels 11 and is fixed mechanically. For example, we stitch and sew the socket 50 through the rigid panel 11, on each side of the angle 2, without stitching the angle 2 nor the assembly member 3, to consolidate, reinforce and stiffen the framework of the barrel 110, composed of angles 2, rigid panels 11 assembled by engaging the L-shaped edges of each rigid panel 11 in a groove 21 of an angle 2 and by fixing the angles 2 between them via the assembly members 3. The same goes for the opening lid 120.

This increases the robustness of the trunk system 1.

As shown on the , according to one embodiment, we therefore stitch the sockets 50 onto the rigid panels 11. To this end, we stitch through the sockets 50 and through the rigid panels 11. The stitching 51 through the rigid panels 11, in particular in self-reinforced thermoplastic material, and the sockets 50, to sew the sockets 50 to the rigid panels 11, makes it possible to consolidate the framework of the barrel 110. The same goes for the opening cover 120. This protects the edges of the framework of the barrel 110 and the junctions of the assemblies of angles 2 and rigid panels 11 are masked. The same goes for the opening cover 120.

At the same time, the trunk system 1 according to the invention maintains a flexibility adapted to absorb mechanical stresses suffered by the trunk system 1, making it possible to increase its strength and durability. Indeed, in the embodiment involving stitching in particular, the sewing threads do not pass through the angles 2 nor the assembly members 3. As a result, there remains a possibility of the rigid panels 11 sliding in the grooves 21 of the angles 2 and a very limited possibility of pivoting around the angles 2. This effect is also obtained with other mechanical means of fixing the sockets 50 to the rigid panels 11, such as nails or rivets.

The faces of the parallelepiped structure of the barrel 110 obtained are thus perfectly parallel. The same goes for the opening lid 120.

The opening cover 120 is thus assembled in a similar manner to the barrel 110. A cover frame is made from angles 2 and rigid panels 41 like those shown in the figure. . The angles 2 have a groove 21 in which is respectively engaged an edge 42 of a rigid panel 41, for example made of self-reinforced thermoplastic material. The angles 2 are fixed together via an assembly member 3. The assembly member 3 comprises for example three feet 31, each foot 31 comprising a fixing member cooperating with a complementary fixing member belonging to each end of the angle iron 2, so as to fix angles 2 to an assembly member 3 to form a right angle corresponding to the vertices of the parallelepiped framework of the opening cover 120.

Then, according to one embodiment, reinforcement means (reinforcement frame, strap) and accessories (wheels, telescopic rod, handles, locks) can be assembled, as shown in the figure. .

To this end, one or more reinforcing frames 81 are provided. There is preferably one in the barrel 110 and another identical in the opening cover 120 fixed on the vertical angles 2, that is to say the angles 2 extending orthogonally to the rigid panel 11 forming the bottom of the parallelepiped framework of the barrel 110 and/or the opening cover 120.

The reinforcing frame(s) 81 can be sheathed using canvas or any other suitable facing material, such as leather, decorative sheet metal, etc. Therefore, it is possible to install a thermoformed or non-thermoformed lining from the inside of at least one of the parallelepiped frames, in particular inside the barrel 110.

According to one embodiment, a sheathed strip 82 is placed against the thermoformed lining of the barrel 110. As is known, a strip 82 is a strip, in particular metallic or of any other suitable rigid material, used for strapping and reinforcing the trunk system 1.

In the opening cover 120, in a similar manner, a lining can be installed on the interior side of the opening cover 120. A separator can also be installed in the volume of the opening cover 120 or any other functional accessory such as elastic or rigid straps, etc.

The reinforcing frame(s) 81 are locked on the framework of the barrel 110 and/or on the framework of the opening cover 120, in particular on the angles 2 of the corresponding parallelepiped framework. We come, through the reinforcing frames 81, in support against the parallelepiped framework of the barrel 110 and we carry out the fixing of the reinforcing frames 81 to the framework. Where applicable, the same applies to the opening cover 120.

The presence of reinforcing frames 81 makes it possible to increase the solidity of the trunk system 1. Optionally, functional accessories are fixed there such as locks 7, hasps (term which designates the movable metal part fixed on the opening lid of luggage such as a trunk to allow it to be closed), hinges 9, fasteners (term which designates leather or metal or textile strips allowing luggage to be kept open). Screw connections are made for locking the structure of the trunk system and fixing these accessories.

The reinforcing frames 81 are preferably made of rigid, light and resistant material, for example aluminum, carbon fiber, ABS, srPP or another self-reinforced thermoplastic material.

The strip 82 can be part of a reinforcing frame 81 or be a separate part. The strip 82 projects relative to the edge of the rigid panels 11, going around the opening of the parallelepiped framework of the barrel 110. The projection produced by the strip 82 is thus orthogonal to the peripheral edge going around the the opening of the barrel 110, constituting a small wall of 2 to 8 mm in height for example, capable of ensuring the guidance of the opening cover 120 of the trunk system 1 during its closing in particular. The strap 82 also contributes to the rigidity between the barrel 110 and the opening cover 120 when using the product (rolling, carrying, etc.).

A reinforcing frame 81 is thus, for example, fixed in the volume of the barrel 110 and another reinforcing frame is fixed in the volume of the opening cover 120.

According to one embodiment, the tops of the trunk system 1 are protected by rigid and removable corners 15. The removable nature of the rigid corners 15 protecting the tops of the trunk system 1 of parallelepiped shape improves the repairability of the trunk system 1 according to the invention.

According to one embodiment, the connection 51 can stop before the vertex, in particular at a distance of between 10 mm and 15 mm upstream of each vertex.

The stitching is for example made approximately 2 mm from the edge of the socket 50.

The thickness of the complex to be stitched, for sockets 50 in leather or lozine stitched in suitable srPP panels, is for example 0.9 mm, with sockets 50 in leather or lozine, a canvas 90 thick between 0.5 mm and 1 mm, rigid panels 11 in multi-ply srPP with a thickness approximately equal to 1.2 mm, i.e. a total thickness of between 2.6 mm and 3.1 mm.
