Abstract

The system has a ventilation device (10) and a channel (30). The channel is opened or closed to open/to close the ventilation device. Edges (13, 14) of the ventilation device are sensibly non-rectilinear. The channel is constituted with two clothes (33, 34) with zip track. The clothes are stitched along the respective edges of the opening in pieces of clothes (11, 12).

Description

The present invention relates to a ventilation system, in particular for clothing, such as as everyday clothing, sportswear, technical clothing, etc ...

The invention is more particularly adapted to the ventilation of sportswear and in the open air and in particular to clothing such as a sports jacket, windbreaker, winter sports jacket, but also pants, shorts, etc.

People working outside or involved in sports or outdoor activities open air are often equipped with waterproof clothing or at least acting as a windbreaker.

A significant disadvantage of windproof or waterproof clothing is their poor ventilation.

Indeed, as the material constituting the garment is waterproof, or at least at wind, it generally constitutes a barrier to the evaporation of moisture emitted by the body during physical exercise, so that the clothes worn underneath can end up completely wet.

The breathability of such waterproof or windproof clothing can be improved by the use of so-called breathable materials, i.e. materials permeable to water vapor but not condensed water (rain). However, these clothes are very fragile and very expensive. Furthermore, their degree of breathability is limited to a given ratio of transmission of water vapor which is not always sufficient for the user, and it occurs therefore always humidity phenomena.

Another way to improve the breathability of such garments is to provide them with means ventilation such as openings that can be opened or closed. The problem of this type of ventilation is to keep the opening actually open so as to allow the air intake, especially when the user is not in motion.

Indeed these openings are generally only slots and means must be provided enlarging these slots and keeping them wide open to obtain a satisfactory ventilation.

The US 6,339,845 plans to combine a system of enlargement of the opening with a slit type ventilation system.

In the examples described, the enlargement system is an elastic means of the type elastic v-shaped pin each of whose branches is associated with an edge of opening and which is compressed during closing.

When the zipper of the opening is opened, it expands automatically under the effect of the elastic pin, thus providing the ventilation system wish.

The aim of the present invention is to improve such a ventilation system, in particular so as to simplify and reduce the manufacturing and assembly costs.

This object is achieved in the ventilation system according to the invention which is of the type comprising a ventilation opening of the slit type and closing means associated with the opening for opening / closing said opening, by the fact that the slot in the opening is substantially non-rectilinear.

Preferably the slot has a substantially oval shape. So in the closed position the material of the edges of the opening is prestressed due to the very cutting of said opening and it therefore widens automatically so as to return to its original shape, not rectilinear, in this case oval, from the opening of its closing means.

With a simple suitable cutting of the opening, we obtain very simply and at a minimum cost the desired goal.

In any case, the invention will be better understood and other characteristics of the latter will be highlighted with the aid of the description which follows with reference to the appended schematic drawing showing, by way of nonlimiting examples, certain modes of preferred realization and in which:

• Figure 8 is a view similar to Figure 1 showing another example of positioning of the device according to the invention.

FIG. 1 shows a garment such as a sports jacket or windbreaker 1 comprising ventilation devices 10, 20 respectively at the armholes and the chest.

Figures 2 to 5 illustrate more precisely the construction of the ventilation device 10 located at the armholes.

As shown in Figure 2, the ventilation device 10 according to the invention is shown between two panels 11 and 12 of the garment, namely in this case a front panel 11 and a sleeve 12 of the garment, and is intended to be closed by a zipper 30.

Of course the inserts 11, 12 can also be provided in different places of the garment and constituted for example by front or rear half-panels of the clothing.

At the mounting zone of the zipper 30 the edge of each yoke 11, 12 is cut into a semi-circular arc respectively 13, 14. The slot defined by these edges 13, 14 is therefore not straight or rectilinear, but of curved shape and in the occurrence substantially oval. These edges 13, 14 are arranged opposite one another and the zipper 30, closed or open, is assembled, for example by seams 40, by each of its ribbons respectively 33, 34 at each of said edges 13, 14.

Of course, other assembly methods than seams (for example by gluing, welding) can be provided between the zipper tapes and the edges 13, 14 of the opening.

Of course the inserts 11, 12 are also assembled together by a seam 50 or similar on either side of the zipper 30. This seam 50 can moreover, at least in part the same as the seam 40.

Once the zipper 30 is mounted, it exerts on each of the edges 13, 14 a tensile force since in fact, due to the circular arc shape of the latter, it "lack" of fabric.

A prestress is therefore exerted on each of the inserts 11, 12, so that as soon as the zipper 30 is open, the edges 13, 14 will automatically move apart and that the ventilation device 10 will offer a wide opening, sufficient for good ventilation.

By a very simple cutting and sewing device, we thus obtain at minimum cost a ventilation device whose opening is enlarged, that is to say the edges of which deviate from each other, automatically when the closing system is opened.

Preferably and as shown in FIGS. 1 and 4, a thread 36 or the like, that is to say a ventilated material, connects the edges 13, 14 of the opening, so that the air inlet takes place, once the zipper is open, through said ventilated material. In the Figures, the teeth of the slide fastener are indicated by the reference numeral 35.

FIG. 6 shows an alternative embodiment in which the opening 20 is made in the fabric itself outside of any yoke.

In this case the edges 13, 14 of the opening in an arc are cut, for example at the hand or cookie cutter in the piece of fabric itself and the zipper is assembled as described above.

Of course the operation after assembly is the same as indicated above.

Figures 7 and 8 illustrate a particularly discreet embodiment in which the zipper 130 is of the type known as invisible closure.

In such a zipper, the tapes 134 supporting the teeth 135 are turned over inward as it closes so that the teeth 135 remain completely hidden when the zipper 130 is closed.

To further perfect the invisibility of such a closure, the inserts 111, 112 are assembled by a turned edge and a hidden seam 140 to each of the ribbons 134 of the zipper.

As a result, almost only the edges of the inserts 111, 112 remain visible when the zipper 130 is closed and only a "line" underlines the presence of the device ventilation 120.

In addition, in the case shown in FIG. 8, the ventilation device 120 is arranged at level of a pliers, that is to say transversely to the garment and therefore remains most discreet.

Of course the present invention is not limited to the embodiments described above by way of nonlimiting examples.

This is how, for example, the slot could have a shape other than oval, or that closing means other than a zipper could be provided without any is therefore outside the scope of the present invention.
