Description

FIGURES

[0068] FIG. 1: This is an overview of different elements of the frame, which can be combined with specific shapes. The base (B) is here rectangular, slightly wavy. The two opposite triangular side faces (L1, L2) are positioned (fixed or mobile) on the shortest edges (A1, A2) of (B). These two opposite triangular lateral faces (L1, L2) can be made of a flexible or rigid material, possibly with at least one axis of rotation inscribed in their plane. The two opposing side faces (L3, L4) of rectangular shape are curved towards each other. The two opposite side faces (L3, L4) of curved rectangular shape are positioned (fixed or movable) on the longest edges (A3, A4) of (B). The two opposite side faces (L3, L4) fit the wavy shape of (B) and consist of a plurality of triangular facets (F) advantageously connected in a movable manner to each other (not shown, for example by a fabric), facilitating thus the opening of the useful pocket of the bag, once the latter has been made

[0069] FIG. 2: This is a plurality of example bases (B) according to the invention. The FIG. 2.1., FIG. 2.2. and FIG. 2.3. represent bases (B) of very slightly wavy rectangular shapes, solid (FIG. 2.1.) or hollowed out (cavities (V)) according to FIGS. 2.2. and 2.3. FIG. 2.2. represents a base (B) consisting of four rods connected to each other at the ends, thus forming a large cavity (V). FIG. 2.3. represents a base (B) comprising several cavities (V), here the cavities are rectangular in shape. The FIG. 2.4., FIG. 2.5. and FIG. 2.6. represent 3 solid bases with more marked undulations or twists than in the cases of FIG. 2.1, 2.2. or 2.3.

[0070] FIG. 3: This figure represents some examples of possible shapes of bags that can be obtained according to the present invention. The shape represented in FIG. 3.1. is characterized by a marked twist of the base (B). In contrast, the shape shown in FIG. 3.2. is characterized by a lack of torsion of the base (B), but which presents a domed shape. The form shown in FIGS. 3.3. and FIG. 3.4. are characterized by two opposite side faces (L1, L2) of different shapes. In FIG. 3.3., The opposite faces (L1, L2) are for one triangular and for the other oval. In FIG. 3.4., the opposite faces (L1, L2) are for one triangular and for the other rectangular. The bag of FIG. 3.4 is also characterized by the presence of a cover (C). In FIG. 3.5., The opposite faces (L1, L2) are hexagons.

[0071] FIG. 4: This figure represents a classic type handbag (with conventional fillings/covers) according to the present invention.

[0072] FIG. 5: This figure represents an embodiment of a handbag according to the invention. The general shape corresponds to FIG. 3.1. FIG. 5.1. represents the bag closed, whilst FIG. 5.2. represents the bag open, revealing the useful pocket (P). A series of magnets (A) enable to keep the bag closed. The side face (L1) is constituted of three moving parts (E1, E2, E3) one with each other; these parts can be rigid or flexible. The intersection of these three pieces defines an upside-down Y. It is the same for the opposite face (L2). The side faces (L3, L4) consist of a plurality of twisted and/or curved rectangles (R) fixed in a movable manner to the base (B), and in a movable manner with respect to each other (for example by the bias of a fabric placed/glued inside the useful pocket (P)).

[0073] FIG. 6: This figure represents another embodiment of a handbag according to the invention. The exterior shape is similar to the bag of FIG. 3.1. The embodiment according to FIG. 6 distinguishes itself by side faces (L1, L2) made of elastic fabric, by hollow frame elements and lined with fabric, and by its lateral faces (L3, L4) made up of a plurality triangular facets F hollowed out of their rigid material and lined with fabric, arranged “head to tail”. The triangular facets F are distributed in a movable manner relative to the base and can be movable to one another.

[0074] FIG. 7: This figure represents another embodiment of a handbag according to the invention. The exterior shape is similar to the bag of FIG. 6. The embodiment according to FIG. 7 distinguishes itself by several (two, here) basal parts (B) connected to each other by an axis of rotation inscribed in the plane of each basal part. The axis of rotation (and therefore of attachment of the basal sub-parts) is in the longitudinal direction of the bag, and the rigid lateral faces L are arranged sequentially in the longitudinal direction and attached in a fixed (or mobile, not shown) manner to the basal part (B)

EXAMPLES

Example 1: Frame

[0075] Different materials have been used to make the frame according to the present invention.

[0076] The general shape of the frame is described in FIG. 6.

[0077] The plastic 3D printing process (A) used an EOSINT M280 machine with Nylon PA12 powder.

[0078] The laser method (B) (DLMS “Direct Metal Laser Sintering”) described used an EOSINT M280 machine with titanium powder TI64 or TiCP.

[0079] The molding process with plastic (C) referenced here by way of comparison concerns one of the classic molding methods using machined molds and conventional plastic polymers (polyethylenes, polypropylenes, epoxy polymers, polyesters, polyacrylates, polystyrenes, etc.).

Example 2: Bag Comprising a Frame According to the Invention

[0080] Handbags according to the invention were made according to FIG. 4, 5 or 6. The linings were placed on the frames using techniques customary in the art (by stitching with reinforcements discreetly glued to the areas of greatest wear). The frame can be more or less visible from the outside. For example, the handbag according to FIG. 4 does not show any frame which is fully lined (covered with fabric. In contrast, the embodiments according to FIGS. 5 and 6 clearly show the different elements of the frame.
