Abstract

Made from a sheet of neoprene (1) which is punched by hand with a predetermined template, depending on the model, thereby supplying the shape of the glove (9), which is similar to the shape of standard gloves (9), but leaves the medial and distal phalanges of the fingers (11) bare. Said sheet (1) is covered with one or two layers of polyamide (2) by means of a thermal-sealing system. Although it is not a feature of all models, the back is normally formed by a double mesh of nylon (5). An interdigital elastic textile (6) joins these two meshes (5) to the neoprene. The finger (11) ends have a edging (8). In the wrist zone a velcro strip (4) closes the glove and is finished in a narrow strip of polyamide (2).

Description

POLYAMIDE COATED NEOPRENE GLOVES FOR SPORTS USE.

The present invention relates to gloves for sports use, made of neoprene and coated with polyamide. Neoprene, a common name for polychloroprene, is a polymer of the chloroprene elastomer. It is the object thereof to have gloves for use in sports that are capable of maintaining their initial state for years. The main characteristics of said initial state are flexibility and elasticity. Another important advantage to highlight is its hygiene, since the neoprene is hydrophobic, its easy cleaning, rinsing and rapid drying minimizes the fixation of microbial agents to its tissue and the consequent presence of unpleasant odors. The polyamide coated areas, due to their composition, make the gloves very breathable. Another important advantage is due to the nature of the neoprene itself: its hypoallergenic nature. This property gives the gloves a pleasant and comfortable touch while providing good protection in the areas covered. If this is added to the fact that the grip of the neoprene on most of the dry and wet surfaces is unbeatable and that it is an excellent thermal insulator, the object of the present invention is perfectly justified. It has its field of application in the glove industry, specifically sports gloves and even more specifically sports neoprene gloves.

Numerous sports gloves are known in the market, made of different synthetic materials, such as rayon, nylon, latex or natural, such as leather, cotton, rubber. It is also known to use silicone gels or breathable membranes such as Gorotex or others, and some for specific sports, for example, diving or cycling. The use of cotton fabrics, skins or synthetic materials in

The development of gloves, presents as its main drawback its poor stability, since they lose the characteristics of their initial state quickly with use. The elasticity, flexibility or hygiene of this type of gloves is quickly lost with the passage of time and its use, while they wear out or bulge, accumulating odors or dirt.

Neoprene gloves are also known for surgical use, such as those described in the translation of European patent ES 2 208 747 T3, developed to combat allergic responses produced by medical gloves of natural rubber in people predisposed to develop an allergic reaction to latex . Part of the medical literature has suggested that the response to the allergen is especially high in the use of rubber gloves in areas of medicine, due to the continuous exposure of health professionals. However, the resistance to dispense with natural latex has always been associated with the unpleasant sensation, or different, of all other synthetic offers, including neoprene, silicones and other types of materials.

Neoprene surgical gloves now on the market have not had the desired acceptance and popularity, because they give a feeling of compression and consequently reduce the flexibility of the users' hands, preferring these to be soft for use in the field of Ia surgery. Hence, the neoprene surgical glove attempts to give a feeling of softness equal to or better than that of the usual surgical glove constructed of natural latex. But the neoprene surgical glove is very different from the one used in sports, since it does not seek the isolation of the skin, but the best grip of the hand, reasons why the neoprene sports gloves do not cover the tips of the fingers

In this same sense, document ES 2 263 270 T3 refers to gloves made from neoprene copolymers for medical use free of the need to powder with talc, puncture resistant, tensile, tensile, 500% and stretching to breakage, also presenting an insignificant discoloration and minimal adhesiveness to themselves and to the glove conditioning materials, after irradiation sterilization.

The advantages that the neoprene offers for the sports gloves proposed herein are based on the fact that they maintain the characteristics of flexibility and elasticity typical of their initial state for years, that is to say, they have a much greater stability. They are also easy to clean, rinse and dry quickly, since the neoprene is water-repellent, which implies greater hygiene, absence of odors, also collaborating in it the polyamide that covers them, which makes them very breathable. Its touch is pleasant and comfortable while providing good protection in the areas it covers. Another advantage of neoprene is its excellent grip on both dry and wet surfaces. It is also an excellent thermal insulator. If we add to this the specific properties of the neoprene we will have gloves that resist degradation due to sun, ozone and weather, which has acceptable resistance to solvents and chemical agents, which is resistant to damage caused by flexion and The torsion.

The polyamide coated neoprene gloves for use in sports object of the present invention are constituted from a neoprene sheet that is hand cut on a specific template, according to model, to give rise to the shape of the glove, which is similar morphologically to that of gloves common, but exposing the middle and distal phalanges of the fingers. Said sheet is covered by one or both sides of polyamide by means of a heat sealing system and has different thicknesses depending on the piece to be made. Although not in all models, the normal thing is that the back is made of nylon, forming a double mesh with an inner face made up of 0.5 mm pores and an outer one with ellipsoidal pores whose axes have 2 to 4 mm. respectively. Between the fingers, these two meshes are joined to the neoprene by an elastic fabric composed of 80% polyamide and 20% elastane. This double mesh while protecting, greatly facilitates the perspiration of the hand. The nylon pieces are obtained by the same die-cutting process as the neoprene ones. The said nylon pieces with their grid structure are sewn to the neoprene and the elastic fabric between the fingers, being arranged on the back of the hand, thus making it possible to better aerate the limb by not covering a non-contact area with neoprene with the object. Another detail is the fact that the end of the fingers is edged in the extreme area of the fingers, preventing the tissue from degrading as it is a zone of high friction.

The closure, by means of a sailboat, is carried out in the area of the wrist where a finish consisting of a narrow polyamide band is determined. On models in which the neoprene is coated with Polyamide only on one side, the one that remains uncoated can be smooth or rough.

The neoprene sheets that are intended to reinforce the palmar area of the gloves are also punched, without them necessarily being covered with polyamide. If so, the thickness of the polyamide is 2 mm. In one of the models this same sheet is used to make the thumb. The neoprene that forms the reinforcement sheets and the thumb shows rugged relief. Different pieces and accessories are added to each model by sewing, such as the thumb, the bridges to accommodate the fingers, the neoprene band that surrounds the thumb, the sailboat that forms the closing system and in almost all The models are added a piece of neoprene, previously punched, 2 mm thick, in order to reinforce the palm of the hand. In addition to sewing, this piece is glued with a contact adhesive along its surface, and can take various forms, depending on the model.

In a different embodiment of the invention metal clips are incorporated into the gloves that allow their closure in replacement of the sailboat. For this purpose, the neoprene is punctured in the area destined for this purpose and the automatic clips are fixed by pressure. In this embodiment the glove is cut in the form of a mitten fingers clipped, fixing the clips, some at the ends of the central area and others, in turn, at the ends of a piece that bends over itself at the level of the finger openings until closing by said system, thus leaving the mitten ready to introduce the fingers of the hand. The clips fit the two pieces with snap or snap.

Alternatively, the outer face of the palmar area of the glove can be reinforced in its central part with an ellipsoidal piece of 2 mm neoprene, attached entirely to the first sheet and sewn on the periphery. In this case, it is punched out with an elliptical central area and wings-shaped extensions, on both sides. On these wings a sailboat is sewn, which will be the one that allows, when folding the glove on itself, that it can be closed for use, by introducing the hand through the channel that forms. Its final disposition will be on the palm of the hand.

In another embodiment, it is the neoprene sheet itself that has extensions that form bridges when sewing, thus allowing the fingers of the hand to be accommodated, the proximal part being straight as a continuation of the wings and the closing system also by sailboat in the wings

Regarding the thickness of the neoprene and the dimensions, it must be said that these may differ between the different models, according to the resistance and areas of the hand to be covered, always respecting the structure and shape of each model. Also the reinforcement of the palm, like the wings, can encompass and protect a larger area in the palm of the hand. Also, the size of the sailboat may differ between some models and others, depending on the greater or lesser support that is desired.

An alternative embodiment has a band that originates in the inner wing of the glove and is inserted in the middle of the edge next to the glove, so that when it closes, it surrounds the thumb giving it greater coverage, protection and support to the hand.

In another model _^, wings and the center cover much of Ia wrist, and the die is open just below the thumb, which allows adding and gluing the part backseamed neoprene form the finger. When the piece is closed, it is like gloves on the hand, exposing the knuckles and a large part of the fingers. The part of neoprene that is in contact with the fingers is trimmed to give a greater protection and therefore duration to the material.
