Description

Adjusted sportswear

The present invention relates to fitted sportswear, in particular it relates to sportswear for the endurance race.

The application FR 2 889 033 describes fitted sportswear comprising portions composed of a laminated compound, one of whose layers comprises a plurality of cuts. Such clothing improves blood circulation and facilitates recovery after exercise but does not provide sufficient muscle support. By WO 98/36652 it is known to produce fitted garments consisting of an elastic base fabric such as lycra ® on which elastic resistance bands are sewn. These elastic bands exert an elastic resistance to the movement so as to help bodybuilding. However such a garment is made to strengthen the body so that it is rather made to resist muscle rather than to give a postural support. The document US Pat. No. 7,631,367 also describes a sports garment which comprises elastic bands stuck or sewn on the textile, the objective of which is to store a portion of energy produced by a muscle during a movement, in order to be able to restore it. during the next opposite movement. Such tape has a small width between 1 and 5 cm because wider bands, for example that would go around a thigh or arm would be too much resistance and would be an embarrassment for the athlete rather than help.

All the prior art documents showing sportswear that have been designed for jogging or running have been for sports practicing on the flat, athletic track, road, etc. and they are suitable not perfectly to the new practice of "Trail-running", or race on the road, in particular running in the mountains. The trail-running is characterized by a race in a rugged environment with in particular portions with high elevation gain (amount) and portions with high altitude drop (down). When it comes up, the muscular energy developed is a power energy that requires a good blood circulation with an optimal venous return but also a good ventilation of the body. On the way down, the muscular energy developed is mainly directed towards postural maintenance. The athlete must maintain at each step his posture and not collapse under pain of losing much of its inertia. This is what makes the difference between walking down where a relative slump of the posture with each step helps to dampen the pace, and the descent by walking where the slump is much less and where there is continuity of time. inertia. The trail-running is characterized on the other hand by a very large variety of land on which the practitioners run, rocks, scree, sand, grass, earth, mud, etc ... but also by the fact that the land is usually not flat and are dotted with stones, roots, ruts, puddles, etc .... Adaptation to this variety of terrain and obstacles solicits not only the feet as it is the case in the traditional jogging, but the whole body so that it maintains permanently its balance whatever the local inclination of the ground. The practice of trail running is very recent, there is no specific product developed for it.

The objective of the invention is to provide sportswear that allow the athlete to free themselves from the disadvantages of current clothing, including providing a garment that offers an optimal compromise between compression, ventilation and postural support. The object of the invention is also to provide clothing particularly adapted to the practice of trail running.

The object of the invention is solved by providing a sportswear intended to cover at least one member of a user having a textile base carried essentially in contact with the body and comprising a compression zone surrounding said member, said compression zone being obtained by affixing a mesh film on the textile base, and comprising a postural holding zone which is included in said compression zone. Said compression zone is provided to surround a part of a limb or part of the trunk of the user and said postural retention zone is placed along a limb or part of the trunk of the user without go around. Preferably, said mesh film comprises a plurality of openings separated by a grid, and the openings are formed according to a repeating pattern of cutting.

In practice, said compression zone can be decomposed into an exclusive compression zone, which is obtained by the apposition of a first film on the textile base and in a postural holding zone, which is obtained by the apposition of a second film on the textile base, the portions of the garment constituted by the textile base and the second film having an elongation resistance lower than that of the portions constituted by the textile base and the first film. Preferably, said second film is also a grid film comprising a multitude of openings. In one is the other of the films, the openings have an area of between 30 and 200 mm 2, preferably between 60 and 170 mm 2. Preferably, in the compression zone, respectively in the postural holding zone, the proportion of area not covered by the first film, respectively the second film, is between 40% and 80%. In one embodiment of the invention, the first film is a PU elastic film and the second film is a textile film, said first and second film being affixed by gluing to the textile base. In one embodiment of the invention, the first film and the second film are affixed to the same side of the textile base, preferably the outer side. In one embodiment of the invention, the first film is affixed to a first side of the textile base and the second film is affixed to the opposite side.

Preferably, the postural support zone extends beyond said compression zone. When said textile base is made by assembling at least two panels, it will be possible to affix the first strand on a first panel and the second strand on a second panel. FIG. 1 depicts a trail-running practitioner equipped with three pieces of clothing according to the invention: a T-shirt 1, a shorts 2, and a pair of leggings 3. In accordance with the invention, each of its garments comprises areas where a compression effect is obtained by a particular configuration. In a nonlimiting manner, four zones are described here: compression zone of the calf 4, compression zone of the thigh 5, compression zone of the thorax 6 and the compression zone of the arm 7. Of course, the clothes being symmetrical right / left, there is a right thigh area and a left thigh area and the same for the arm and calf, but for reasons of simplicity we will speak later of the thigh area. In addition, it is possible to envisage other common compression zones at the forearm level in the case of a long-sleeved T-shirt. Figures 2, 3 show respectively a T-shirt of the invention in front and back view. T-shirt 2 consists of a textile base 10 on which are placed at different locations films. The textile base 10 is made up of different main panels: a front panel 101, two side panels 102, a back panel 103, two handle panels 104, and a number of secondary panels such as that used to make the neckline. 11. The main panels can be assembled by different processes such as sewing, gluing or welding. The textile base can be woven or knitted. In the various embodiments described herein, the textile base is extensible and is obtained by knitting. A first compression zone is provided on the T-shirt 2, which is the compression zone of the thorax, which completely surrounds the thorax in a band of average thickness of between 5 and 15 cm. In some places, such as the sternum, the local thickness of the strip may be slightly less than 4 cm. However, a certain continuity of the compression band is always carried out so that the compression zone completely surrounds the member concerned, here the torso. According to the invention, the compression zone is not uniformly made. It is decomposed into an exclusive compression zone 61 in which only a compression effect is desired and a dorsal postural retention zone 62. The dorsal postural retention zone 62 is obtained by gluing a textile film on the back panel 103 The bonding is for example achieved by the establishment of a thermofusible film between the textile panel and the textile film. The exclusive compression zone 61 is obtained by bonding a polyurethane film on the side panels 102 and on the front panel 101.

FIG. 4 shows a portion of the exclusive compression zone 61. The elastic polyurethane film which is bonded to the textile base 10 is, beforehand, cut so as to provide a grid 17 which surrounds a plurality of openings 16 of shape hexagonal. In this position hexagons where two opposite sides are horizontal, we speak of horizontal position of the grid constituted by the elastic film. FIG. 5 represents a portion of the dorsal postural retention zone 62 showing the detail of the cuts formed in the textile film 12 before its bonding. The textile film 12 is a tight weave much less elastic than the textile base of the main panel 10 constituting the T-shirt. The thickness of this film is between 5 and 30 microns, preferably between 10 and 15 microns. It is provided, for example by laser cutting, a plurality of cuts in a repetitive pattern. We choose to make the cuts in a hexagonal form given the advantages offered by this form, although other forms of cuts are also possible. We are talking here about the vertical position of the hexagons or the grid. The size of the hexagons and the thickness of the links of the grid that surrounds them are chosen so that the compromise between postural support, compression effect and aeration of the skin is optimized. In practice, a pattern whose area is between 30 mm 2 and 200 mm 2 and preferably between 60 and 170 mm 2 is chosen. The thickness of the links of the grid is between 1 and 7 mm, preferably between 1.5 and 5 mm. Another way of determining the correct sizing of the patterns of the cuts and the width of the links of the grid is to consider the percentage of area of openings relative to the percentage of area covered by the grid on an area entirely covered by the textile film 12 It will be possible to choose a repeating cutting scheme such as the total area not covered by the film 12 and comprised between 40% and 80% of the total area of the area under consideration.

In the example described in Figure 4, the dimensions of the hexagon are 10 mm between two sides and each link of the grid is 3 mm thick, so that the uncoated area corresponds to about 60% and the area covered by the film 12 corresponds to about 40% of the area of the postural maintenance zone. It should be noted that these measurements are made while the garment is not worn, and since it is a garment intended to be adjusted to the body of the user and to compress in some places, there is has an elongation of certain portions of the garment when it is worn. It is estimated that the average elongation of the garment when in place on the user is between 5% and 25%. An optimal elongation would be about 15%. Figure 6 illustrates two particularly interesting effects of the device according to the invention.

This is a detail sectional view of the garment worn at the dorsal postural support zone 62. When the garment is worn, the epidermis 13 is compressed mainly at the portions of the back panel 103 covered by the film 12. The regions of the epidermis 13 which are only covered with the back panel have a certain ease and as can be seen, they can very slightly swell. Thus in these regions, the epidermis breathes better and can aerate more easily because the physiological functions that manage the thermoregulation are not hindered by too much compression. On the other hand, the effect of compression is partial insofar as unlike medical clothing, it does not apply to the entire area of the muscle. Thus, it is a compression that is better suited to a sport. Preferably, the sportswear according to the invention will be worn directly on the skin of the user so that the effects of compression, postural maintenance, massage and aeration of the skin are maximum. According to the invention, the area of compression at the level of the thorax is constituted by the exclusive compression zone 61 and the lower part of the dorsal postural holding zone 62, the one which in alignment with the exclusive compression zone 61 constitutes a bandage completely surrounding the thorax. Relative to the circumference of the compression zone, the lower part of the dorsal postural support zone corresponds to a portion between 10% and 40% of the circumference of the compression zone. For an "L" size T-shirt with a chest measurement of 76 cm, the width of the lower part of the dorsal postural support zone is approximately 13 cm. For reasons of aesthetics, the cutting patterns of the PU film 14 (polyurethane) are identical to those of the textile film 12, they give an impression of continuity. The dorsal postural support zone 62 extends upwards to join another postural support zone, the postural support zone of the shoulders 73.

The choice of a PU elastic film for the compression zone and a textile film for the postural support zone is not limiting in the context of the invention. Indeed, the compression zones and the postural support zones can be made in different ways. For example, the compression zone may be made by printing, that is to say depositing a material in a repeating grid pattern in liquid or semi-pasty form on a textile base. The postural support zone can also be made by affixing a PU film. In another embodiment, the textile base, the areas of compression and postural support are integrally performed by knitting. In this case, the knitting of the compression zone defines a grid tightening the garment by a certain factor relative to the rest of the garment and the holding zone included in the compression zone defines an even more compressive grid.

The postural shoulder support zone 73 extends from the compression zone of the right arm 71 to the compression zone of the left arm, passing near the neck of the T-shirt. Figures 7 and 8 respectively show front and rear views of shorts according to one embodiment of the invention. This is a fitted shorts or jogging shorts mainly made by assembling different textile panels. For example, these textile panels may be made of a material similar to that sold under the trade name Lycra. Of course, many equivalent textile bases may be used in the context of the invention.

Contrary to what was done for the description of the T-shirt, we will not go into the details of the assembly of the different textile panels. Moreover, apart from the hems and the belt, these panels are not shown in the figures. According to the invention, the short is improved by the presence of compression zone and postural support zone, the postural holding zone being partly included in the compression zone. The compression zone of each thigh 5 is provided to completely transversely surround the entire limb, here the right or left thigh, or most of it. Longitudinally, the compression zone covers a large part of the main muscles of the thigh, namely, the adductors, the hamstrings and the femoral quadriceps. In practice, the longitudinal extension of the compression zone of the thigh is between 5 and 40 cm, preferably between 8 and 30 cm. In this case, for shorts of size L (wide), the compression zone of the thigh extends over 20 cm. The compression zone of the thigh 5 comprises an exclusive compression zone 51 placed in particular on the front and the back of the thigh, and an internal postural support zone thigh 52 and the lower part of an external postural retention zone. Thigh 53. Relative to the circumference of the compression zone, the postural internal and external support zones of the thigh represent a proportion comprised between 10% and 40% of the total circumference of the thigh compression zone.

The external postural support zone 53 extends upwards beyond the compression zone of the thigh 5. Associated with the internal postural support zone 52, it ensures a very good stability of the posture of the sportsman, especially during the phases of descent. In a variant not shown, only an external postural holding zone 53 is placed on the textile base, the inner zone being replaced by the extension of the exclusive compression zone 51. With such shorts, the postural support will remain present but in a lesser extent. As for the T-shirt described above, the exclusive compression zone 51 is made by bonding an elastic rope on the textile base. The film is cut in a repetitive pattern of openings all having a diamond shape. The area of the areas not covered by the film represents between 40 and 80% of the area of the exclusive compression area thigh 51. The postural support zone outer thigh 53 and the postural support zone inner thigh 52 are made by bonding a textile film 12 on the textile base 10. The textile film 12 is cut in a repetitive pattern of cuts so as to produce a grid framing a plurality of apertures each having a diamond shape. The size of the lozenges is slightly smaller than that of the diamonds of the exclusive compression zone of the thigh 51, thus giving it greater resistance to elongation. In a variant (not shown) of the shorts of FIGS. 7 and 8, the postural external support zone thigh 53 extends to and including in the belt 15.

Figure 9 shows a detail view of a short according to another embodiment of the invention. The shorts are made in the same manner as the shorts described with reference to FIGS. 6 and 7 and comprise compression zones and postural support zones placed in the same places as those of the short of FIGS. 6 and 7. The difference lies in the shape of the openings in the polyurethane elastic film of the exclusive compression zone and in the textile film of the postural support zones. These are of identical shape and size to those described with reference to FIGS. 2 to 5, that is to say hexagonal. In addition, as can be seen in Figure 9, the textile film 12 is placed on the inner face of the textile base while the elastic film 14 is placed on the outer face.

Thus, the mesh film which constitutes the postural support zone is directly in contact with the skin. This has the effect of improving proprioception to help the user to balance his posture, especially in the descent phase. TABLE 1 Traction / Textile Base Traction / Hex Force (N) Gap / Textile Base Gap / Compression Zone Short: Textile Base Single Chain 2 Weft 1.5 Short: Horizontal Chain Area 5.5 x 2.8 Compression Vertical Weft 6.25 x 4.2 Shorts: horizontal chain support zone 10 x 5 x 1.8 vertical grid 9 x 6 x 1.4 Test tube 1: vertical chain base 7.75 x 3.9 textile + PU film horizontal grid 5.5 x 3 , 7 Test specimen 2: vertical chain base 10 x 5 x 1,3 textile + textile film horizontal weave 10 x 6,7 x 1,8 Table -1- above shows different tensile measurements performed on the short of the figure 8 and two test pieces. The measurement protocol is as follows: two layers of one portion of the shorts are attached to 25 mm wide and 100 mm apart shores are pulled until an elongation of 15%. This pulling force is measured in Newton. As the measurement is made on two layers, it is easier to carry out non-destructive measurements on clothes already made. The shorts are made by assembling the textile panel, knitted in a chain, placed in such a way that the warp threads extend vertically. The hexagonal grid is arranged vertically (see fig.5), so that a traction made in the direction "chain" is made in the horizontal direction of the hexagons while a traction made in the direction "frame" is made according to the vertical direction of the hexagons.

Specimens 1 and 2 consist of a textile base identical to that of the shorts on which is fixed a PU elastic film 14, respectively a textile film 12, similar to those used for shorts, but with the hexagonal grid placed in such a way that the horizontal direction of the grid is parallel to the "warp" direction of the textile base.

The presence of the PU elastic film increases the tensile strength of the textile base in the transverse (horizontal) direction by a factor of between 2 and 7, preferably between 3 and 6. The increase in tensile strength due to the presence of the postural holding textile film is of the order of a factor of between 3 and 9, preferably between 4 and 8 in the "warp" direction as in the "weft" direction. For example, for the short described in Figure 8 this factor is 4.2 for the increase in transverse tensile strength of the exclusive compression zone and 6 and 5 respectively for the increase in tensile strength transverse and vertical of the postural support zone. The postural support zone is more resistant to traction than the exclusive compression zone, in both vertical and horizontal directions by a factor between 1.1 and 3.

Specimens 1 and 2 show that it is possible to obtain similar results by modifying the relative orientation of the hexagonal grid with respect to the "warp" direction of the textile base. In practice, to make a sportswear according to the invention, it is possible to combine different textile panels having non-parallel "chain" directions and / or mesh films whose grids have different orientations (see FIGS. .

Figures 10 and 11 respectively show the front view and back of a leg 3 according to the invention. It consists of a textile base made of an assembly of different woven or knitted panels having a certain elasticity on which is attached a textile rope 12, defining the calf postural support zone 42 positioned along the tibia and an elastic film 14 defining an exclusive compression zone calf 41.

According to the invention, the calf compression zone 4 surrounds the calf of the user and is constituted by the juxtaposition of the exclusive compression zone calf 41 and the calf postural support zone 42.
