Description

VENTILATED CLOTHING

Technical area

The invention relates to the field of clothing incorporating ventilation means capable of capturing the outside air to distribute it inside the garment.

The invention can be applied to a large number of garments. Preferably, the invention relates to a garment for covering at least an upper part of the human body, such as jackets, anoraks, coats, cardigans, parkas and coveralls.

The invention finds a particularly advantageous application for ski clothing which protects from the cold and includes ventilation means to improve the comfort of the user.

Previous techniques

Ski clothing conventionally comprises an outer layer and an inner lining. The outer layer provides the interface between the garment and the outside air. This outer layer is generally made of an insulating material impermeable to water and air. The internal lining provides the interface between the garment and the user. This internal lining is conventionally made in a comfortable and breathable fabric. The cold insulation of the garment can be provided both by the material of the outer layer and by the presence of an air space between the outer layer and the inner lining or, an additional insulating and warm layer can be added between the outer layer and the inner lining for example.

However, this insulation from the outside cold also forms a tight barrier which prevents the evacuation of perspiration due to the efforts of the user. As a result, the user may experience too much warmth.

To solve this problem, document WO 2014/002067 proposes a ski jacket with vents between the external layer and the internal lining to ventilate the interior of the jacket. Two front vents are provided on the front face of the jacket substantially facing a user's chest region. These front vents collect outside air to ventilate the user's chest areas. Two rear vents are provided on the rear face of the jacket substantially facing a region of the user's lumbar vertebrae. These vents allow ventilation of the sides of the user's back.

However, the ski jacket described in this document WO 2014/002067 does not allow specific regions to be effectively ventilated because the vents cause air to propagate throughout the volume of air present between the outer layer and the lining.

Typically, it is desired to ventilate the armpits or specific regions of the back of the user in which the phenomenon of sweating is most important during efforts. With the solution of document WO 2014/002067 it is not possible to ventilate these regions effectively without ventilating important regions of the jacket due to the constraints linked to the positioning of the vents. Indeed, it is preferable to position the vents facing the direction of movement of the outside air to capture a maximum amount of air. Thus, it is not possible to effectively capture the outside air by positioning vents facing the armpits because the sleeves of the jacket would at least partially block the arrival of air. Likewise, the vents positioned in the back of the jacket of document WO 2014/002067 do not effectively capture the outside air because they are not arranged facing the direction of movement of the outside air when the user moves on a track. ski.

The technical problem of the invention is therefore to ventilate specific regions of a garment by limiting the constraints of positioning the vents in order to effectively capture the outside air.

Statement of the invention

The invention proposes to respond to this technical problem by providing at least one air conduction channel having air-impermeable walls between an air inlet opening formed on an external layer and an extraction opening d air formed on an inner layer.

Way of carrying out the invention

Figures 1 and 2 illustrate a ski jacket 10 having an outer layer 11 structured to form a front face 46 and a rear face 49 of the jacket 10 to which two sleeves 12 are fixed. The sleeves 12 are arranged symmetrically with respect to a central longitudinal axis A1 of the front face 46. The opening and closing of the front face 46 is ensured by a zipper 14 or zipper extending along the longitudinal axis central Al. The front face 46 extends between a neck 47 and a lower front edge 48. The central longitudinal axis A1 is defined as the axis passing through the middle of the neck 47 and the middle of the lower front edge 48 .

Although Figures 1 and 2 illustrate a jacket 10, the type of clothing is not limiting and the invention can be applied to anoraks, coats, cardigans, parkas and combinations, with or without sleeves, with possibly a hood. Likewise, the shape of the jacket 10 in FIGS. 1 and 2 is not limiting and the invention can be adapted to an asymmetrical garment 10, from the point of view of its structure or even of its closure means. The jacket 10 of Figures 1 and 2 can be cut into two parts 19-20 in the height direction: an upper part 19 extending above a horizontal axis A2 and a lower part 20 extending below of this horizontal axis A2. The upper part 19 is intended to come opposite a pectoral region of the user while the lower part 20 is intended to come opposite a ventral region of the user.

The upper part 19 is provided with a hood and two pockets 15 symmetrically arranged with respect to the central longitudinal axis A1. The openings of the pockets 15 are arranged parallel to the axis A1 and at a distance of between 0.5 and 5 cm of the central longitudinal axis A1. The volume of each pocket 15 is understood to be under the outer layer 11 in the direction of the sides of the jacket 10.

The lower part 20 also includes two pockets 16 symmetrically disposed with respect to the central longitudinal axis A1. The openings of these pockets 16 are also arranged parallel to the axis A1 but at a distance of between 10 and 35 cm from the axis central longitudinal Al as a function of the size of the jacket 10 so that these pockets 16 are accessible on the front face of the jacket 10 close to the side of the jacket 10. The volume of each pocket 16 is understood to be under the outer layer 11 in the direction of the central longitudinal axis Al.

In another embodiment, the pocket openings could be inclined relative to the longitudinal axis A1, and the number of pockets could also vary.

The outer layer 11 is made of a more or less extensible material which is impermeable to water and air, such as a polyester fabric possibly based on elastane covered with an impermeable membrane, for example by heat welding. As a variant, the external layer 11 can also be formed by a complex of several juxtaposed and / or superimposed materials. In the example of FIGS. 1 and 2, two pieces 17, symmetrically arranged in the upper part 19 facing the armpits of the user, are produced by a knit of extensible polypropylene so as to improve the freedom of movement of the user .

Besides the outer layer 11, the jacket 10 also has an inner lining or inner layer 45, illustrated in FIG. 4. This inner layer 45 provides the interface between the user's body and the outer layer 11.

It can be glued or sewn with the outer layer 11 at several points to guarantee the passage of an air layer between the outer 11 and inner layers 45, the air being in particular a good insulator. The internal layer 45 is produced by a breathable material, of the lycra, mesh or polycotton type for example.

As a variant, the internal layer 45 can also be formed by a complex of several juxtaposed materials and include specific parts intended to increase the comfort and / or elasticity, or even the heat of the internal layer 45, for example by using parts of neoprene, or fleece pieces.

Other layers of the wadding or down type, in particular insulating against the cold, can also be added between the inner layers 45 and the outer layers 11.

The invention relates to the communication, by an air conduction channel 40a-40b, of at least one air inlet opening 21a-21a ', 21b-21b' capable of capturing the air present at Exterior of the garment 10 with an air extraction opening 41, 42, 43 formed in the internal layer 45.

In the example of FIG. 1, the lower part 20 of the outer layer 11 is provided with two air inlet openings 21a-21a 'symmetrically arranged with respect to the central longitudinal axis A1 above the openings in the pockets 16 In the example of FIG. 2, two air inlet openings 21b-21b 'are symmetrically arranged with respect to the central longitudinal axis A1 between the openings of the pockets 16 and central longitudinal axis A1.

Other positions can also be used for the air intake openings 21a-21a ’, 21b-21b’ without changing the invention, for example in place of the pocket openings 15 in the upper part 19.

Figures 3a-3b illustrate an example of an air inlet opening 21a-21a, but other types of air inlet opening can be used without changing the invention. This air inlet opening 21a has two lips 22-23 arranged opposite one another and joined at their upper 26 and lower 27 ends.

The lips 22-23 can be joined by closing means 24 of the zipper or zipper type. Alternatively, the closure means 24 may correspond to loops and hooks or to at least one press button.

In a preferred but non-limiting embodiment of the invention, the air inlet opening is provided with a blade-type spacing means 28 to keep this air inlet opening open and thus favor the air intake and efficiency of the ventilation system.

When the zipper 24 is closed, as illustrated in FIG. 3c, the two lips 22-23 are joined. The length XI of the opening 21a is between 100 and 200mm, preferably about 150mm. The distance Y1 between the two lips 22-23 depends solely on the thickness of the zipper and can be between 5 and 15 mm. A spacer means such as a blade 28 is fixed between these two lips. A first end 29 of the blade 28 is fixed substantially in the middle of a length of a first lip 22 and a second end 30 is fixed substantially in the middle of a length of a second lip 23.

The blade 28 has a longitudinal axis A4 extending perpendicular to a median longitudinal axis A3 of the air inlet opening 21a. The blade 28 is fixed by gluing or sewing on the lips 22-23. Preferably, the blade 28 corresponds to a semi-rigid blade produced by a thermoplastic material.

In the closed position of FIG. 3c, the blade 28 is deformed and partially or totally folded back on itself inside the air inlet opening 21a.

When the zipper 24 is open, as illustrated in FIGS. 3a and 3b, the lips 22-23 are separated from one another by forces F1 of deployment of the blade 28. These forces F1 are imposed according to the longitudinal axis A4 of the blade 28. The blade 28 is then partially or completely unfolded and returns to its initial shape which can be flat or curved.

The spacing of the lips 22-23 by the blade 28 makes it possible to reach a maximum distance Y2 between the lips 22-23. Thus, the distance Y2 is between 30 and 50mm depending on the blade 28 chosen which is a good compromise to promote the entry of air through the air intake openings 21a-21a ’, 21b-21b’. The distance Y2 corresponds at most to the length of the blade 28 or may be less than this length if the blade 28 is still deformed.

The thickness, width and length of the blade 28 are chosen to obtain a desired force F1. In the example of FIGS. 3a-3c, the spacing of the lips 22-23 is obtained with a single blade 28.

Alternatively, several blades can be used in a complementary manner in order to reduce the thickness or the width of these blades to obtain the same force F1. In addition, the shape and orientation of the blade 28 can vary as long as the blade 28 crosses the air inlet opening 21a to spread the lips 22-23.

In addition to moving the lips 22-23 in the plane of the outer layer 11, the air inlet opening 21a may include a reinforcing rod 31 capable of moving a lip perpendicular to the plane of the outer layer 11.

This rod 31 is preferably made of plastic material such as polyurethane or nylon for example. Its section can be of various shapes of circular or oval or even polygonal type. This rod 31 is elongated and very thin. In the case of a circular section, its diameter is preferably between 1 and 3mm.

In the example of FIGS. 3a-3c, a reinforcing rod 31 is arranged along the lip 23 and the ends 32-33 of the rod 31 exceed the ends 26-27 of the lips 22-23. The rod 31 is fixed on the lip 23 and on the outer layer 11 at its ends 32-33 and is mounted prestressed. In particular, its curvature is oriented towards the outside of the jacket 10 in a plane perpendicular to the outer layer 11 to further promote the entry of air.

In the example of Figures 3a-3c, a single rod 31 is used. Alternatively, the air inlet opening 21a may include a rod 31 on each lip to stiffen these lips 22-23. A rod 31 can also be placed on each air inlet opening 21a in FIG. 1 at the lips 22-23 closest to the zipper 14.

According to the invention, the air inlet openings 21a-21a ', 21b-21b' are used to ventilate an area arranged opposite air extraction openings 41 to 43 connected to the inlet openings d 'air 21a-21a', 21b-21b 'by at least one air conduction channel 40a-40b.

In the example of FIG. 4, a rear face 49 of the jacket 10 has three air extraction openings 41 to 43 arranged in an upper part of the jacket 10. The rear face 49 extends between a neck 47 and a rear lower edge 50 of the jacket 10. The upper part extends above a horizontal median axis A6 positioned midway between the neck 47 and the rear lower edge 50.

In this upper part of the rear face 49, the three air extraction openings 41 to 43 are arranged according to the diagram of the flower petals. To do this, the three air extraction openings 41 to 43 have a teardrop shape with a base and a profile extending from the base. The three bases are grouped together towards the same central point disposed on an axis A5 passing through the middle of the neck 47 and the middle of the rear lower edge 50. A first air extraction opening 41 has a profile oriented on the axis A5 towards the rear lower edge 50 to ventilate the upper back at the level of the user's spine. The two other openings 42-43 are arranged at a distance of between 0.5 and 5 cm from the axis A5 and extend symmetrically with respect to the axis A5 towards the edges of the neck 47, to ventilate the upper back and in particular the user's shoulder blades area.

FIG. 4 illustrates an example of air extraction openings 41 to 43 but other types of air extraction openings 41 to 43 can be used without changing the invention, these openings 41 to 43 possibly be more or less numerous depending on the use of the garment 10. For example, two air extraction openings can each be arranged under a sleeve 12 on each side of the jacket 10. Likewise, the extraction openings of air can have many and varied shapes.

In addition, the air extraction openings 41 to 43 may be covered with an airy fabric provided with holes, the fabric being able to be a mesh fabric of the net or mesh type, or even a fabric of the perforated polyester or polyamide type.

In this example, the shape of the holes can also vary without changing the invention and the holes of diameter or width greater than 1 mm, preferably between 1mm and 5mm, make it possible to obtain efficient evacuation of the air ducted in the air conduction channels 40a-40b. The holes can also be obtained by perforating the fabric and in particular by laser perforation.

In the example of FIG. 4, the air conduction channel has an inverted T shape with two branches 40a-40b and a vertical branch 40c. The vertical branch 40c of the T extends along the vertical axis A5 and the lateral branches 40a-40b of the T extend along the horizontal axis A6. Each lateral branch 40a-40b of the inverted T is connected to an air inlet opening 21a-21a ’and the vertical branch of the T is connected to the air extraction openings 41 to 43.

The vertical branch of the T has a width Y4 less than a width Y3 of the rear face 49. The lateral branches 40a-40b of the T have a width X4 at a junction with the vertical branch of the T which is less than a width X3 at the air inlet openings 21a, thus forming a narrowing of section 51, to create a Venturi effect which makes it possible to accelerate the air coming from the air inlet openings 21a-21a ', 21b -21b 'to the air extraction openings 41 to 43.

The air conduction channel 40a-40b can be made by an airtight sleeve with a first end fixed with at least one air inlet opening 21a-21a ', 21b-21b' and a second end fixed with at least one air extraction opening 41 to 43.

As a variant, the air conduction channel 40a-40b can be produced with an air-impermeable part connected with the internal layer 45 or the external layer 11 so that the air conducts through the air conduction channel 40a-40b is channeled between the impermeable part and the inner layer 45 or the outer layer 11.

The invention thus makes it possible to conduct the air captured by at least one air inlet opening 21a-21a ', 21b-21b' to at least one air extraction opening 41 to 43, distant from the air inlet opening 21a-21a ', 21b-21b', to ventilate specific areas of a garment 10.

In the case where the air extraction openings are positioned under the sleeves 12 of the garment 10 in the inner layer 45, the garment 10 then has two distant air extraction openings and two independent ventilation channels are necessary for provide ventilation.

Each of these channels makes it possible to connect an air inlet inlet 21a21a ’, 21b-21b’ located on the front of the garment 10 to an air extraction opening located under the user's arm.
