Description

TECHNICAL FIELD

The disclosure concerns a reinforced-support bra adapted for athletic use.

BACKGROUND

There are essentially two familiar types of bra adapted for sports use, namely, the compression type and the encapsulation type bra.

The compression type bra has a front portion, generally in the form of a band, which compresses the breasts to limit their movements and swaying.

This type of bra is felt as being uncomfortable by the users.

Furthermore, by compressing the breasts this type of bra can injure the breasts.

The encapsulation type bra comprises a first cup and a second cup to enclose each breast and thus act independently on the movements of each breast.

This type of bra does not compress the breasts and it respects the health of the breasts.

Whether of compression or encapsulation type, the bra comprises a front portion, in contact with the breasts, which is generally made by molding or by sewing.

By molding, the front portion of the bra is shaped by a molding process, such as thermal molding, of one or more materials, especially textile materials.

By sewing, the front portion of the bra is shaped by a traditional tailoring of one or more pieces of textile materials which are arranged according to their mechanical properties.

Furthermore, it is known how to reinforce the front portion by adding resin or accessories of framing type, regardless of the fabrication process.

These different types of bras, in order to be effective and adapted to athletic use, require a complex and difficult fabrication owing to the many materials used and their fabrication process.

SUMMARY

The present disclosure intends in particular to solve these inconveniences and in doing so it involves a bra adapted for athletic use, of the type comprising:

• • a first cup and a second cup belonging to a front portion of the bra, each of them bounded laterally by an outer edge and by an inner edge, and
  • a back fixation strap which is connected to the outer edge of the first cup and to the outer edge of the second cup,

characterized in that each cup is outfitted with a support structure and a base structure, the support structure comprising at least one support strap of overall cradle shape which is elastically deformable and which extends at least from the outer edge to the inner edge of the associated cup, to support the breast.

The bra according to the disclosure makes it possible to limit the weight of the materials needed for its manufacture while still guaranteeing an effective supporting of the breasts.

Moreover, the elongated support elements, thanks to their slender shape and their elasticity, contribute to the comfort, the lightness, the aesthetics and the ergonomics of the bra.

According to one preferred embodiment, the support structure comprises at least one second support strap of overall cradle shape which is elastically deformable and which extends at least from the outer edge to the inner edge of the associated cup, to support the breast, the first strap and the second strap being arranged so as to cross and form a support meshing zone at each cup.

The crossing of the straps allows an interaction between the straps and makes it possible to create “fastening points” contributing to the supporting of the breasts.

Preferably, the meshing zone is arranged in at least a lower half of each cup.

According to another characteristic, the first second support strap of the first cup and the second support strap of the second cup form a central reinforcement zone in which said straps are crossed, said central reinforcement zone being arranged in an upper central part of said front portion of the bra, to support the breasts.

Advantageously, the first strap is at least partly shared by the first cup and the second cup.

This characteristic favors the realization of the first strap.

According to another characteristic, the first strap and the second strap form a central reinforcement zone in which said straps are crossed, said central reinforcement zone being arranged in an upper central part of said front portion of the bra, to support the breasts.

The crossing of the straps enables an interaction between the straps and makes it possible to create “fastening points” contributing to the supporting of the breasts.

Likewise, the bra has a plane of symmetry of general design extending vertically between the first cup and the second cup.

The disclosure also concerns a manufacturing process for a bra of the type comprising at least:

• • an assembly step consisting in assembling the first strap and the second strap of the support structure on the base structure, and
  • a molding step which consists in molding the assembly comprised of the base structure and the support structure, to form the front portion of the bra.

According to a first embodiment of the process, the assembly step consists in applying the first strap and the second strap to the base structure of the bra by silk screening.

According to a second embodiment of the process, the assembly step consists in assembling the front portion of the bra by superpositioning a front layer, a back layer, and an intermediate layer, the intermediate layer forming the internal support structure.

In this second embodiment, said layers are assembled by hot gluing.

According to a third embodiment of the process, the assembly step consists in embroidering the first strap and the second strap on the base structure of the bra.

According to a variant embodiment, the process involves a single molding stage which consists in simultaneously molding the base structure and the support structure to form the front portion of the bra.

DETAILED DESCRIPTION

There is shown in FIG. 1 a bra 10 adapted for athletic use, being shown in a configuration as worn by a person standing upright.

The bra 10 has a first cup 12a and a second cup 12b which belong to a front portion 13 of the bra 10.

The two cups 12a, 12b are aligned transversely and arranged on either side of a plane of symmetry P of general layout of the bra 10, visible in FIG. 1.

To facilitate an understanding of the specification, the identical and symmetrical elements according to the plane of symmetry P are distinguished by a reference numeral followed by the letter “a” or “b”.

Each cup 12a, 12b is bounded transversely by an outer edge 14a, 14b and by an inner edge 16a, 16b, respectively.

Moreover, each cup 12a, 12b has an overall hemispherical shape, with convexity oriented to the front in a longitudinal direction.

The bra 10 has a back fixation strap 18, visible in FIG. 3, which is composed here of a first web 20a and a second web 20b which can be connected to each other at the back of the person using the bra by a movable attachment means (not shown) of the type with a hook and complementary catches, for example.

The first web 20a of the fixation strap 18 is joined to the outer edge 14a of the first cup 12a and the second web 20b of the fixation strap 18 is joined to the outer edge 14b of the second cup 12b.

In a nonlimiting fashion, the bra 10 can also be designed for attachment in front, between the two cups 12a, 12b, according to a sample embodiment not represented.

Likewise, the bra 10 can be made into a tube without attachment means, to be slipped on over the head.

The back fixation strap 18 is made of knit which can stretch in a transverse direction corresponding to its long dimension, for example.

Moreover, the bra 10 is outfitted with a pair of suspenders (i.e., shoulder straps) 24a, 24b which are designed to support the bra 10 on the shoulders of the person wearing it.

According to the disclosure, each cup 12a, 12b is equipped with a support structure applied to a base structure 11 which forms the backbone of the bra 10. The base structure 11 is made of knit, for example.

The support structure of each cup 12a, 12b comprises a first support strap 25a, 25b and a second support strap 27a, 27b, respectively, each having an overall cradle shape, that is, a concave curved shape with concavity oriented overall toward the top.

The first straps 25a, 25b and the second straps 27a, 27b are elastically deformable and they extend from the outer edge 14a, 14b respectively of the associated cup 12a, 12b, to the inner edge 16a, 16b respectively of the associated cup 12a, 12b, in order to support the breasts.

Moreover, the first support straps 25a, 25b are formed by a first series of elongated elements 28a, 28b respectively, which are elastically deformable and which extend in overall parallel manner to each other, and the second support straps 27a, 27b are formed by a second series of elongated elements 30a, 30b respectively, which are elastically deformable and which extend in overall parallel manner to each other.

It is meant by elongated element, any slender element, such as a strap or a cord, for example.

Also, the elongated elements 28a, 28b, 30a, 30b can have different elasticities.

The elongated elements 28a, 28b of the first series, being six in number according to the sample embodiment described here, are superimposed and comprise three upper elongated elements 28a, 28b each of which has an upper piece 32a, 32b extending overall vertically from the base of the suspender 24a, 24b.

The upper pieces 32a, 32b thus constitute a support sling which works overall vertically as shown by the arrows F1, to support the cups 12a, 12b respectively, participating in the supporting of the breasts.

Moreover, as can be seen in FIG. 2, the upper elongated elements 28a, 28b of the first series each have an inner piece 34a, 34b which extends overall transversely from the central plane of symmetry P, such that the upper elongated elements 28a, 28b of the first series are shared by the first cup 12a and the second cup 12b.

According to another aspect, the elongated elements 30a, 30b of the second series, likewise six in number according to the sample embodiment described here, are superimposed and comprise five elongated elements 30a, 30b each of them having an upper piece which extends in oblique manner from the neckline 38 of the bra 10, such that the upper pieces belonging to the first cup 12a and the upper pieces belonging to the second cup 12b form a central reinforcement zone Z1 in which these elongated elements are crossed in an X to promote the support at the center of the bra 10, as illustrated by the arrows F3.

Advantageously, each crossing of two elongated elements creates an anchoring point enabling an interaction between these two elongated elements to favor their mechanical strength.

As can be seen in FIG. 2, the upper elongated elements 30a, 30b of the second series each have an outer piece 40a, 40b which extends overall transversely to the straps 20a, 20b respectively.

According to another aspect of the disclosure, the elongated elements 28a, 28b of the first series and the elongated elements 30a, 30b of the second series are arranged so that they cross to form a first support meshing zone Z2 at the first cup 12a and, by symmetry, a second meshing zone Z2 at the second cup 12b.

Preferably, each meshing zone Z2 is arranged in at least a lower half of the associated cup 12a, 12b.

The crossing of two elongated elements 28a, 28b, 30a, 30b in each meshing zone Z1, Z2 produces an essentially cradle shape providing a bidirectional elasticity to each cup 12a, 12b, as illustrated by the arrows F2 in FIG. 2. This crossing makes it possible to increase the elastic rebound force of the elongated elements 28a, 28b, 30a, 30b so as to support the breasts and reduced the vertical movements.

The bra 10 according to the disclosure can be manufactured by a manufacturing process as described below.

The process involves an assembly step which consists in assembling the elongated elements 28a, 28b, 30a, 30b of the support structure on a base structure forming the backbone of the front portion 13 of the bra 10.

The assembly step is followed by a molding step which consists in molding the assembly comprised of the base structure and the support structure to form the front portion 13 of the bra 10.

The molding step is preferably accomplished by thermal molding, which makes it possible to give shape to the two cups 12a, 12b and reinforce the mechanical bonding between the base structure and the support structure.

According to a first embodiment of the process, the assembly step consists in applying the elongated elements 28a, 28b, 30a, 30b to the base structure of the bra 10 by silk screening.

According to this first embodiment of the process, the elongated elements 28a, 28b, 30a, 30b are preferably made of silicone, which makes it possible to lighten the bra while still providing a satisfactory elastic rebound.

As an example, the material used to manufacture the base structure of the front portion 13 of the bra 10 has a molding temperature lower than the melting temperature of the silicone so that the elongated elements 28a, 28b, 30a, 30b preserve their physical elasticity characteristics.

According to a preferred example, the base structure is made of knit of three-dimensional type, known as “3D knit”, or of a three-dimensional monofilament separation fabric, composed of 89 percent polyamide fibers and 11 percent elastane fibers, and having a density of 375 grams per square meter.

According to a second embodiment of the process (not represented), the assembly step consists in assembling by hot gluing the front portion of the bra 10, involving a superpositioning of a front layer and a rear layer designed to be in contact with the skin, the front layer and the rear layer forming the base structure.

As a supplement, an intermediate layer is interposed between the front layer and the rear layer.

The intermediate layer here forms the internal support structure, the elongated elements 28a, 28b, 30a, 30b being cut in the intermediate layer for example in the form of thin strips by a laser cutting process.

According to this second embodiment of the process, the intermediate layer is preferably made of three-dimensional monofilament separation fabric of the type composed of 87 percent polyester fibers and 13 percent elastane fibers, and it has a density of 255 grams per square meter.

Likewise, the front layer is preferably made of jersey knit of the type composed of 80 percent polyamide fibers and 20 percent elastane fibers, and having a density of 80 grams per square meter.

Likewise, the rear layer is preferably made of jersey knit of the type composed of 78 percent polyamide fibers and 22 percent elastane fibers, and having a density of 330 grams per square meter.

According to a third embodiment of the process (not represented), the assembly step consists in embroidering the elongated elements 28a, 28b, 30a, 30b on the base structure of the bra 10.

The elongated elements 28a, 28b, 30a, 30b are, for example, elastically deformable cords or threads which are resistant to heat.

In fact, according to this third embodiment, the molding step of the assembly formed by the elongated elements 28a, 28b, 30a, 30b and the base structure is preferably carried out by thermal molding.

Finally, according to one variant of the previously described embodiments, the process involves a single molding step which consists in simultaneously molding the base structure 11 and the support structure made from a single piece of material in order to form the front portion 13 of the bra 10.

For this purpose, the base structure and the support structure of the bra 10 are placed for example in a mold and thermally molded together, so as to assemble them and shape them at the same time.

The present specification of the disclosure is given as a nonlimiting example.
