Description

Cool clothing.

The present invention relates to a refrigerant garment and more particularly to a refrigerant suit.

In. normal conditions, and particularly when metabolic activity is high, heat and humidity are factors that can impair an individual's sporting performance. For this reason it is advantageous to provide active cooling to the individual.

Clothing is known which is maintained under pressure by gas, for example carbon dioxide (CO2), contained in a pressure vessel. The document FR2619315 describes such a garment.

WO1991 / 04722A1 discloses a cooling device for cooling a body by evaporation of liquid on the outer surface of the garment.

EP0348835A2 discloses a protective clothing congre accelerations comprising a heat transfer fluid circulating in a closed loop in a heat exchanger.

WO2004 / 064554A1 discloses a coolant sportswear comprising a cooling zone formed by a hydrophilic textile surface. All of the achievements of the prior art are generally complex and not adapted for high-level physical exercises. Indeed, the clothing associated with the achievements of the prior art are heavy, often do not allow great freedom of movement and are limited in effective heat exchange with the individual in physical activity.

The invention improves the situation. To this end, the invention introduces a cooling jacket, comprising a woven structure shaped according to a human bust, on which are mounted one or more heat accumulators. The woven structure comprises applied inner side pockets that surround the top of the shoulders, said pockets enclosing a heat accumulator and said woven structure being substantially integrally made of light and elastic fiber.

According to one embodiment, the heat accumulator (s) are of heat accumulator gel bag character. According to another embodiment the woven structure further comprises applied inner side at least one upper back pocket.

According to another embodiment, the woven structure further comprises, applied internally, at least one upper pocket of the torso.

They are an integral part of the description, and may therefore not only serve to further the understanding of the present invention, but also contribute to its definition, if any.

We return briefly to the effects of heat during exercise.

As discussed above, heat and humidity are factors that can impair the physical performance of an individual. To limit the deleterious effects of heat, especially during endurance events, there are various methods that use body cooling before exercise (also called precooling).

These methods increase the ability to evacuate body heat, thereby allowing an athlete to maintain a high level of performance in a warm and humid environment. However, the mechanisms used in body cooling are still poorly known.

The Applicant has discovered that targeted cooling, on selected parts of the human bust, allows a lowering of the average body temperature in unexpected proportions. The lowering of temperature is associated with an increase in performance. According to one embodiment, the invention allows an improvement of about 8% to 11% of the average power developed during a physical exercise of about 20 minutes.

It will be understood in what follows, that the invention also allows a return of cold during or after physical activity.

The targeted cooling of the invention is achieved by means of thermal accumulators. According to one embodiment of the invention said thermal accumulators are heat accumulator gel bags. The gel-type heat accumulators have the advantage of conforming to the shape of the body, thus allowing a plating against the skin to increase the heat exchange surface.

The gel bags suitable for carrying out the invention are especially the Gelpack bags sold by the company PEARL Diffusion [reference: PE4716-903]. These Gelpack bags allow a return of cold for a relatively long period, and have proved to be particularly suitable for incorporation into a light garment, close to the skin contact, against which it is tightened elastically.

Gelpack bags have the advantage of cooling quickly in a freezer or by immersion in cold water. Generally 1 hour is sufficient for refrigeration. Figures 1 to 4 show different perspective views of an inverted cool suit. It will be understood that by returned refrigerant jersey is meant a jersey whose inner side is turned outward to show its structure. During the implementation of the invention, the jersey is obviously in the place as in Figure 4 or 5.

Figure 1 shows a side perspective view of a jersey 100 refrigerant returned. The jersey 100 is a short-sleeved T-shirt (T-shirt or T-shirt) and is entirely made of a woven structure 102 made of material including elastane (also known as spandex or elastane). It is a copolymer of polyurethane and elastic polyethylene glycol, lightweight and resistant to perspiration. A material of this type makes it possible to press the heat accumulator (s) against the body for the reasons of exchanges of heat mentioned above. In addition, elastane is known to almost not deform after repeated deformations. Thus, the plating of the heat accumulators against the body is ensured even after persevering use of a suit according to the invention.

According to one embodiment, the material of the woven structure 102 of the jersey 100 is of the so-called Lycra 150g type, available in France in particular from the company Yalouz Sport in Besançon. Such a jersey allows great freedom of movement due to its elasticity and good breathing of the skin. Lycra 150g lets pass and evacuate sweat.

The jersey 100 includes a shoulder pocket 110 substantially at each shoulder. A shoulder pocket 110 is entirely made of woven structure 102 and forms a lining. By pocket is meant a housing adapted to receive one or more heat accumulators of the gel bag type as shown in Figure 6. The pockets may be formed by lining material.

Generally, the thermal accumulator gel bags 600 preferably used for combination with the shirt 100 have a width of about 13 cm and a length of about 26 cm. This allows a heat exchange surface sufficient for good thermal cooling.

According to the embodiment of Figure 1, the thermal accumulator gel bag 600 is slid by a shoulder opening 104 giving access to the shoulder pocket 110. Once slipped, the gel bag 600 marries the shape of the shoulder human and surrounds the upper shoulders to allow effective heat exchange.

Figure 2 shows a perspective view of the back of a jersey 100 refrigerant returned. According to the embodiment described here, the jersey 100 includes a back pocket 112 located substantially at the top of the human back. In a similar manner to that described for the / shoulder pockets 110, the back pocket 112 is adapted to receive a heat accumulator gel bag 600 through a back opening 106.

Figure 3 shows a front perspective view of a jersey 100 refrigerant returned. According to the embodiment described here, the jersey 100 further comprises a chest pocket 114 located at the top of the torso. The chest pocket 114 is adapted to receive a thermal accumulator gel bag 600 through a thorax opening 108.

FIG. 4 shows a front perspective view of a 100 refrigerant jersey comprising several heat accumulator gel bags 600, namely a bag at each shoulder, a bag at the level of the upper back and a bag at the top level. torso.

A shirt 100 like that shown in Figure 4 can effectively control the body temperature of people exercising intense physical activity and particularly in hot and humid environmental conditions. The manufacture of the jersey 100 in a material comprising elastane allows adaptation to any human morphology and great freedom of movement. In addition, an elastane textile and heat accumulation gel bags 600 are particularly light and allow a realization of the jersey 100 in a weight not exceeding 1300g. A jersey according to the embodiment described in the present description makes it possible to sustainably diffuse a cold of approximately 6 ° C against the body.

Figure 5 shows a side perspective view of a short refrigerant suit. A short jersey is commonly called top and differs from a classic jersey, like that of Figures 1 to 4, due to the lack of material at the bottom of the human bust. Generally, a short jersey does not cover the belly button and allows a great freedom of movement and a high ventilation.

The short jersey 200 is, like the jersey 100, entirely made of a woven structure 202 made of a material comprising elastane.

According to one embodiment, the jersey 200 comprises two shoulder pockets 210, a back pocket (not shown in FIG. 5) and a breast pocket 214.

Each pocket is made by lining and accessible through openings for accommodating heat accumulator gel bags 600. According to the embodiment described here (see FIG. 5), a lateral opening 204 allows access to a breast pocket 214 of a part and a first shoulder pocket 210. A similar opening (not shown in Figure 5) allows accessibility to a second second shoulder pocket 210. The back pocket is accessible by any suitable opening and the like to the side opening 204 , placed dorsally on the shirt 200.

It is noted that the invention described herein relates essentially to body cooling before physical exercise and a return of cold during or after physical activities. However, the invention is not limited to this embodiment. In particular, the jersey described here also allows an active restitution of the heat by the use of appropriate thermal accumulators. Indeed, Gelpack bags can be used for such an application. To warm the gel bags, simply place them in a micro oven for example. The jersey described above in combination with heated gel bags, thus allows a return of heat for activities or this is necessary, especially in winter sports.
