Description

INVENTION FIELD

The present application claims the priority benefit of Brazilian Patent Application No. BR 1020120310589 of 6 Dec. 2012.

The present invention describes a clothing for the practice of aquatic sports equipped with lumens for filling in of air and the respective welding method of the lumens' periphery through sinuous or broken welding lines which assure the maintenance of the elasticity and amplitude of movements, avoiding the rigid areas that appear when the technique of straight line collage is used.

INVENTION PRECEDENTS

The clothing for aquatic sports is generally made of neoprene, an elastomeric material provided with elasticity and high resistance which allows thermal comfort to the user. However, this clothing does not present means to assure the user's survival in case of water immersion for a long time, or, yet, does not present means for assuring its floating.

Thus, deaths of surfers and other aquatic sports practitioners through drowning are not avoided. For example, in case of a consciousness loss in water or immersion for a long time, the clothing does not present any means to maintain the user floating, in a manner to assure oxygenation and life.

Patent number BR0104789, from the same holder, describes a life-saving clothing made of waterproof material having a series of lumens or compartments positioned next to the neck, throughout its front and back portions, whereby such compartments retain a special gas derived from a chemical reaction which maintain the lumens inflated in order to keep the user's head and nose outside of the water, avoiding death through drowning in case of eventual unconsciousness.

The state of the technique describes other solutions, such as the document BRPI9600469, which presents an anti-drowning safety device attachable to pieces of clothing that involves an inflatable vest made of waterproof thermoplastic material, which is rolled down in the form of a thick belt and attached to the waist of a piece of clothing by means of a Velcro® fastener or the like, said of a device having a small reservoir containing air under pressure, having a needle valve commanded by a pin next to its shaft.

The document BR0102839 describes an inflatable multiple multi-user life-saver which involves an inflatable recipient with a cavity that crosses it from one side to the other, forming a type of tunnel or chamber, whose interior contains a fastening device destined to fix and maintain the individual totally safe and protected, during rescue, and devices capable of inflating and/or emptying and shooting gases with great expansion power in the container's inside.

Considering the clothing used for the practice of aquatic sports, generally with elastic surface, the conformation of lumens for the filling in of air is obtained through the collage of two superimposed tissue blades with waterproof properties, where neoprene is conventionally used. However, the collage in straight line or in extense straight segments generates an area deprived of elasticity, which makes the amplitude of the user's movements difficult, mainly in the shoulder region. Still, the collage can generate air overflow in between the tissue fibers, in case it's not accurately made.

Thereby, clothing for the practice of aquatic sports is the object of the present invention, which presents the conformation of lumens with periphery provided of sinuous or angled welding lines that generate a spring effect, providing elasticity which does not limit the user's movement amplitude, situation required in aquatic sports.

Additionally, it's the object of the present invention a welding method for obtaining such lumens applied in clothing for the practice of aquatic sports where alternative forms of tissue welding are predicted in a manner to provide a barrier to air dissipation between the clothing fibers.

DETAILED DESCRIPTION OF THE INVENTION

The clothing for the practice of aquatic sports having lumens for the filling in of air involves a Neoprene® clothing (100), an elastomer made up of dubbed polycloropen rubber with nylon tissue on both faces and with impermeability properties, isothermal and elastic.

The clothing (100) presents in specific areas the disposition of lumens (10) obtained by the welding of two neoprene and/or similar blades superimposed (110), such lumens (10) limited on the periphery by sinuous or angled welding lines (20), in a manner to avoid the formation of an inelastic area when the welding occurs in straight lines.

The lumens (10) can be positioned in the chest's region and/or in the proximity of the neck and/or on the dorsal or lumbar regions.

The sinuous and/or angled welding lines (20) eliminate the conformation of long straight lines that form inelastic areas which make the amplitude of movements more difficult. On the contrary, the sinuous and angled welding lines (20) provide a spring effect, particularly useful in the shoulder's area, where an intense motion of the region for the rowing is required, such as flexion, extension, abduction, hyperextension, adduction and internal rotation.

Optionally, the lumen (10) presents on the inside the arrangement of an inner tube made up of of elastic material (101), as presented in FIG. 4, whose tube (101) can present on the internal surface the application of a layer of paint or similar (21), preferably through silk screen or spatuling process, whose layer of paint or similar (21) which provides a physical barrier to the overflow of air contained in the lumen (10) through the tissue's fibers, as presented in FIG. 6.

Optionally, the lumen (10) presents on its inside the disposition of a tube (102) with its surface provided with intercalated reliefs and undulation, called flat springs (1021), as described in document PI8702823, from the same holder, allowing elasticity to inelastic surfaces, as presented in FIGS. 5 and 5A.

For the filling in of air from the lumen (10) or from the inner tube (101) a bidirectional biting valve (11) is predicted, preferably positioned at the front of the clothing (100), whose valve (11) is within easy access to the user's mouth when wearing such clothing (100), allowing the entrance of air into the lumen(10) or into the tube (101) and return to the lungs, in case of a complementary oxygenation need, through the disposition of the mouth on the valve (11).

Preferably, on the inside of the lumen (10) profiles (12) which move according to the air flow established from the valve (11) aspiration are laid out, such profiles (12) which configure internal protuberances which facilitate the passage of air in its totality, be it on the filling in or emptying of the lumen (10), mainly in strangulation areas, where the material's elasticity can imply in the restriction of exit or entrance of air, as presented in FIGS. 1 and 2.

The lumens (10), by being filled in with air, keep the chest elevated, lessening the effort during the rowing, as is the case when surfing. Still, the lumens (10) assure the user's floating and, according to the form, volume and location, assure the keeping of the head outside the water, added of the possibility of complementary oxygenation, with the air reservoir accessed through the bidirectional biting valve (11).

For the welding of the neoprene, or similar, blades superimposed (110) are applied, in a first modality, at least one layer of an elastomeric adhesive (22) is applied to the welding's internal line (20) from the lumen (10), in a manner to configure a mechanical barrier which can block the exit of air through the permeation by the tissues' fibers, as indicated in FIG. 7.

As a second modality, as presented in FIG. 8A, the lumen's (10) welding line (20) is limited by flaps to make the chemical attack of the tissue's internal face effective by the application of an acid, such as the hydrochloric acid, collapsing the neoprene's lining (110) and configuring an area with thickness reduction and pores elimination (23), as presented in FIG. 8B, conforming a mechanical barrier which impedes the escape of air contained in the inflatable tube (10), as highlighted in FIG. 8C.

The collapsed area (23) from the welding line (20) receives the application of adhesive or similar (22) for the collage, as presented in FIG. 8D.

In a third modality, as presented in FIG. 9, at the lumen's welding line (20) is a trench configured (24) by removing the neoprene blade's internal lining (110), in a manner to eliminate any area with fibers which allow the entrance of air. At the trench (24) is applied, at least, a layer of adhesive product or the like (22) which impedes air overflow, being the welding line (20) next sympathized to the opposing blade (100) through an adhesive (22).
