Abstract

The invention relates to bags, such as transport bags, in particular hand bags, which can be individually customised, using a rigid frame. The invention also relates to the method for the production of said bags, as well as to the various elements relating thereto, such as the packagings thereof.

Description

Customizable bags

The object of the present invention relates to bags, such as transport bags, in particular handbags, individually customizable, involving the use of a rigid frame, their manufacturing process, as well as the various related items, such as their packaging.

The transport bags, in particular the handbags, generally group together often very personal effects such as identity papers, mobile phones, even portable computers, medicines to take regularly, beauty products, jewelry, etc. They are thus considered by their users as intimate goods. However, these transport bags and more particularly handbags, are often produced on a large scale, thus limiting their personalization.

The state of the art reports some examples of bags that can be industrialized on a large scale with means of personalization. For example FR978474 is characterized by a possibility of rapid transformation of the bag. Similarly EP0414656 discloses interchangeable elements at the level of the bag at the whim of the owner. EP2163169 also discloses handbags with interchangeable linings. US2016183649 discloses handbags that can be “customized” with replaceable and interchangeable elements.

However, throughout the state of the art, the general shape of these bags cannot be configured by the user. The state of the art is content to graft and / or interchange elements on bags whose general shapes are already determined by the manufacturer. Indeed, the state of the art considers that the user can, presumably according to their wishes, change the external appearance of their bag with prefabricated elements. Personalization ultimately consists of a combination that can be personalized by each user of prefabricated elements. Moreover, in reality, the user rarely changes regularly the combination of the elements forming his bag. In addition, in all cases, the user does not really have a way out of the possibilities offered by the manufacturer, especially in terms of the general shape of the bag. The object of the present invention differs from this state of the art by proposing additional means for personalizing bags, in particular handbags, by giving the technical means so that the user can obtain a general external shape. of the bag that is the one she / he determined. This general shape is obtained according to the present invention by means of a frame integrated in the bag. This frame is customizable by the computer tool, which makes it possible to implement modular manufacturing tools, such as 3D printing, and in particular laser sintering. By proposing new technical means, the present invention allows the user to actively participate in the manufacture of his bag, at least in its design, and thus obtain a bag which is personal to him.

SUMMARY OF THE INVENTION

The object of the present invention therefore relates to a transport bag frame, such as a handbag, comprising:

- at least one rigid basal part (B) of polygonal shape, and / or

- At least one lateral face (L) at least partly rigid, preferably fixedly attached and / or movable to the basal part (B), where appropriate.

The subject of the present invention also relates to a method of laser manufacturing a metal part for a transport bag, such as a handbag, comprising the following steps:

(a) 3D computer design of said metal part;

(b) transfer of the 3D data obtained in step (a) to a 3D laser manufacturing device;

(c) applying a laser from the device of step (b) to at least one metal, such as a metal powder; and

(d) recovery of the metal part thus obtained in step (c).

In addition, the object of the present invention relates to a transport bag, such as a handbag, comprising a frame as described herein. In addition, the subject of the present invention relates to a transport bag packaging, such as a handbag, intended to contain a transport bag according to the present invention. In particular, the bag intended to contain a bag according to the present invention may include an indication, such as a trademark and / or a suitable shape, making it possible to identify its content, ie the bag according to the present invention.

DEFINITIONS

In the context of the present invention by "frame", it is understood at least one rigid part intended to support and / or maintain the arrangement in the space of the transport bag, such as a handbag. The frame may or may not be visible from the outside of the bag. The frame may or may not be visible from at least one of the useful pockets of the bag. In a particular embodiment, the frame is fully inserted into the bag and is visible neither from the outside, nor from the inside (useful pocket) of the bag. In another embodiment, the frame can be used in technical fields close to that of handbags, such as the field of jewelry boxes, purses or even wallets. The frame can be used as such or with trim.

In the context of the present invention, “transport bag” includes a container, preferably with at least one flexible material, comprising at least one rigid frame as defined above, said bag being designed on the one hand for contain the attributes of one or more people, and on the other hand allow its transport by at least one person. The transport bag includes a base, and at least one side face connected to the base. Preferably, said transport bag, such as a handbag, comprises at least one external gripping means, such as a shoulder strap, a handle, attachment point, etc. allowing its user to grab it and carry it with him / her. Preferably, the transport bag is adapted to be positioned between the arm and a side blank of the body of the user; it is then preferably a handbag containing the personal attributes of the user. The transport bag, such as a handbag, can be made of any flexible material useful for this purpose. Preferably, the materials are high quality materials, such as natural leather, cotton, velvet, wool, silk and even cashmere.

In the context of the present invention, “handbag” includes a transport bag as defined above for daily or occasional use containing often very personal effects such as identity papers, mobile phones , a wallet, wallet, bank cards, jewelry, etc. said personal effects may be intended for everyday use.

In the context of the present invention by "basal part" is understood the basal part of the frame, which is integrated into the base of the transport bag. The basal part of the frame is delimited by its edges and its surfaces. The thickness of the basal part (corresponding to the edge if the thickness of the basal part is constant and homogeneous) is significantly smaller than the length of the latter. Typically, the thickness of the edge is less than one tenth of the length of the edge considered. The basal part of the frame can take any possible polygonal shape. Preferably, this polygonal shape comprises at least one corrugated surface, generally curved and / or twisted.

Preferably, the basal part of the frame is merged with the basal part of a bag, that is to say the part on which the bag rests when it is placed during normal use. It is often referred to as the "bottom of the bag" when it is a handbag because this basal part is merged or adjoins the bottom of the useful pocket of the handbag. Thus, in the case of a handbag with an opening from above, the basal part is the lowest surface facing the opening.

In the context of the present invention by “rigid”, it is understood a material resistant to the forces of torsion, shearing and which does not bend or with difficulty (on a human scale). For example, a rigid material according to the present invention has a Young's modulus greater than or equal to 1 GPa, preferably greater than or equal to 2 GPa, more preferably greater than or equal to 3 GPa, even more preferentially greater than or equal to 5 GPa. Examples of rigid materials according to the present invention include metals or metal alloys including aluminum, silver, chromium, copper, tin, iron, magnesium, manganese, nickel, gold , palladium, lead, platinum, titanium, zinc, zirconium. For example, it can be steel, such as steel stainless steel, rolled copper or alloys comprising titanium.

For example, it may be alumina, chromium carbide, titanium carbide, titanate, barium titanate, carbon, glass fibers, carbon fibers, polyamides, polycarbonates, polystyrene (eg extruded) from epoxy resin, wood, such as bamboo, mahogany, oak, maple, etc.

In the context of the present invention, "polygonal shape" includes a shape having several angles, and therefore several sides.

In the context of the present invention by "lateral face" is understood a planar element adjacent to an edge delimiting the basal part of polygonal shape. In the context of the present invention, the lateral face can be attached directly to the basal part. The side face can be fixedly or movably attached to the basal part. Generally, a movable fastener allows at least two elements to be connected to each other while allowing them certain significant movements with respect to each other. Generally, a fixed attachment, on the contrary freezes the at least two elements and prevents them from any significant movement with respect to each other. The lateral face can be linked to the basal part by its arrangement in the bag, ie it is a flexible material, even elastic, which can make the link between the basal part and the lateral face. A side face can comprise a flexible and / or rigid material. In a particular embodiment, one or more lateral faces may consist of one or more flexible, even elastic, materials. In the case of a side face made of a rigid material, said side face may comprise at least one axis of rotation inscribed in the plane of a surface considered. Thus in a particular embodiment, a lateral face can comprise several facets (F) attached to each other in a mobile manner and giving the necessary flexibility to the lateral face as a whole to allow an opening of the frame (and therefore of the bag according to the invention). Typically, one of the ways to obtain flexibility is to inscribe a Y in a triangular face so that the three ends of the Y correspond to the vertices of the triangle. Rotation axes are then represented by the 3 branches of the Y connected to the vertices of the triangle. In a particular embodiment according to the invention, the facets (F) are of any applicable shape, such as a polygonal shape, for example a triangular, rectangular shape (including of square shape), or of the shape d 'a diamond. Preferably, the facets (F) are triangular in shape.

In the context of the present invention by “laser manufacturing process”, it is understood any manufacturing process involving a laser to physically delimit a part. This process can involve, for example, cutting a part from a material sensitive to laser radiation, or the laser can heat a powder made of a material sensitive to said laser, thus causing the grains making up said powder to be welded. In the latter case, it involves a powder, a process known as "laser sintering". Preferably, the “laser manufacturing method” in the context of the present invention is a method by laser sintering. Examples of applications of such a method can be found in the literature such as documents US5597589, or more recently WO2018115767.

In the context of the present invention, “metallic part” includes any part comprising at least one metal, for example in an alloy. Preferably, the part is completely metallic.

In the context of the present invention by "3D computer design", it is understood that a spatial representation is made using a computer tool, such as a computer (fixed or portable), a touch pad, a notebook, a telephone. portable or even a fablette.

In the context of the present invention by "transfer of 3D data", it includes any means allowing the exchange of data generated by 3D computer design as defined above, from one computer tool to another. Preferably, the data transfer is done from a computer tool dedicated to 3D design in a virtual way to a computer tool dedicated to 3D manufacturing, that is to say linked to tools for real product manufacturing, such as lasers, machining tools, etc. The means allowing the exchange of data generated by 3D computer design can be done by any suitable medium, such as a cable, a wireless network, a USB key, a CD-ROM, a DVD, etc. In the context of the present invention by “3D laser manufacturing device”, it is understood a laser manufacturing device as defined above, dedicated to 3D manufacturing, that is to say using data generated by computer design 3D, as defined above.

In the context of the present invention by "metallic powder" is understood a substance consisting of metallic particles, that is to say particles comprising at least one metal. A powder is characterized by its particle size. Granulometry is the study of the statistical distribution of the sizes of a plurality of solid units (or pieces / granules) of natural or fractionated matter (ie a collection). Particle size analysis is the set of operations used to determine the size distribution of the elements making up a powder. The size distribution is the representation in the form of number tables or graphs of the experimental results of the size analysis. The metal powders which can be used for laser sintering typically have particles with a diameter of between lOpm and 500mth, for example between 20mth and IOOmhi, such as 50mhi ± 20mih.

In the context of the present invention by “recovery”, it is understood any means making it possible to isolate an element from its environment. In this case, it may be a metal part formed by laser sintering in a metal powder used for its manufacture.

In the context of the present invention, “bag packaging” includes an external packaging covering said bag. This packaging can be opaque and / or translucent. The packaging is necessarily larger than the bag it contains. This packaging can be made of a flexible and / or rigid material. The packaging may include or consist of an elastic material allowing it to adapt to the bag that it is supposed to contain. Preferably, the bag packaging according to the present invention is of similar external shape, if not identical to the external shape of the bag which it contains.

The software can also be configured so as to limit the thicknesses of reinforcement in order to obtain a product which can hold and be sufficiently solid. Of course, all of these conceptualization steps can be done directly in a store with the help of a person who will help the client in his design. The software can automatically generate the data necessary for carrying out the packaging for the bag that has been defined by the client. This packaging can be either any flexible or rigid material. The packaging can be carried out by the same techniques as described for the reinforcement of the bag itself (for example by sintering, 3D printing, laser cutting, etc.). Alternatively, the packaging can be made using flexible materials that are more or less elastic in order to adapt to the bag produced by the client.
