Description

Ventilated glove

description

The present invention relates to a glove, in particular winter sports glove with an air chamber which is filled by at least one opening with air, or can circulate through the air.

From the prior art generic gloves are known. Such gloves are used especially in winter for skiing and snowboarding, to protect the hands from the cold.

Although these gloves have been continually improved over time, for example by the use of so-called climate membranes, which are to prevent the ingress of moisture into the interior of the glove, but it is still very common, especially at low temperatures or humid weather, that the wearer such gloves gets cold hands and especially cold fingers. Of course, this problem also occurs in motorcycle, work, or other gloves. To solve this problem, in the prior art, for example in DE 81 11 943 Ul and DE 37 25 337 Al electrically heatable garment items such as gloves are proposed in which an electrical power source is used to generate heat. However, this solution comes at the expense of handling and wearing comfort. In addition, this solution is dependent on the provision of external energy sources such as a battery. Furthermore, when using such heaters with batteries of disadvantage that uneven heating or overheating occurs, so that the heater must be turned off in between.

It is therefore an object of the present invention to provide a glove which is able by simple means to remedy the above-described cold problem.

According to the invention this object is achieved in that at least in an area of the glove, preferably in the upper hand part, an air chamber is created, whereby the property of air is used as an excellent insulator to advantage.

Accordingly, the present invention relates to a glove, in particular sports glove, with an upper hand part and an inner hand part, which cover the palm, the back of the hand and possibly the fingers of the glove wearer, characterized in that at least in a hand part, preferably in the upper hand part, an air chamber is present, in which from the outside at least one opening for blowing air into the interior of the air chamber. In the prior art gloves have been proposed, in which one can blow air through a valve and thus warm his hand; See, for example, the German utility model DE 200 15 105 Ul. The disadvantage here, however, is that the breath is moist, and thereby the glove can become clammy. Furthermore, one can not warm up his hand during a sports activity. Finally, when blowing through only a limited area of the hand is heated for a short time.

In contrast, with the use of an air chamber according to the invention by the blowing warm breath this is not supplied directly to the hand, but a warming and insulating layer formed in the glove, and thus created an air-heat pad. Due to the inventive design of the glove with an air chamber, the hand fitting glove lining remains dry and the glove can not be clammy.

This air cushion, or hereinafter called air chamber, typically extends from the back of the hand to preferably over the individual fingers and is inflatable by means of an opening, preferably a valve on the back of the hand. In other embodiments of the glove according to the invention, the air chamber can also extend over the palm of the hand to the fingers or parts thereof.

The air chamber in the glove is preferably located between the inner lining and the outer material layer of the glove, for example an outer leather, wherein in one embodiment the material layers of the air chamber are formed such that they themselves form the outer and / or inner end layer of the glove.

The glove of the invention is preferably provided on the glove waistband with at least one opening through which air can enter the interior of the air chamber.

In a preferred embodiment, the hand-facing inner material layer of the air chamber has the properties of a semi-permeable membrane, ie, its permeability to air and moisture is selective. This prevents the penetration of moisture into the interior of the glove. Furthermore, the hands get under power, for example when skiing, slightly sweat, whereby the glove interior can be humid and the feeling of cold hands occurs. By using a semipermeable membrane with appropriate selectivity, this moisture can be dissipated via the air chamber and the inlet and possibly outlet openings adjacent to the glove. Semipermeable membranes are known per se in particular of polytetrafluoroethylene (PTFE), and / or a laminate formed from polyvinyl chloride, polyurethane, polyetheramide, polyetheresteramide, polyolefin components, polyester components, or a mixture thereof. Particularly preferred are polytetrafluoroethylene (PTFE), in particular Goretex material, preferably brand name products such as Aktivent, DryLoft, Gore-Tex (GTX) and Windstopper GTX.

In an advantageous embodiment of the glove according to the invention is located on the side facing the hand of the inner material layer of the air chamber another material layer, which is preferably cuddly. In this regard, especially textile materials are considered, but also leather and imitation leather. In one embodiment, the further material layer essentially consists of nonwoven fabric which gives a pleasant wearing comfort, in particular for winter sports gloves. Furthermore, it can be seen from the above list of substances for the further material layer that preferably breathable, air-permeable materials are used.

In an advantageous embodiment of the glove according to the invention can be provided that the at least one opening is provided with an element for closing the opening. In this way, on the one hand, the air chamber closed after blowing the air to maintain an air cushion, and on the other hand, the penetration of moisture into the air chamber can be prevented.

In a preferred embodiment of this element for closing the at least one opening, this is designed as a valve. In order to keep moisture contained in the injected breath air from the inside of the glove, may be provided in a further advantageous embodiment of the glove according to the invention that in the valve, a membrane for preventing the penetration of moisture is disposed in the air chamber.

If the at least one opening is arranged on the glove closure, in particular on the upper hand part of the glove, this least disturbs the functionality of the glove and also hardly affects the aesthetics of the glove. At this point, the opening and any associated with the opening valve is not considered disturbing and can be achieved very easily with the mouth.

In a further embodiment, the glove according to the invention has at least one second opening, which may be designed in the same way as the at least one opening described above. This embodiment is particularly advantageous when the air chamber is configured so that its inner material layer is permeable to air, so that when openings open air flow to the palm and / or the fingers of the glove wearer -A- can get. In one embodiment, the glove according to the invention can be designed so that it has at least two air chambers, either as completely separate units or separated from an air chamber by, for example, a membrane, wherein the two air chambers have as internal material layer a semi-permeable membrane which is permeable to air, and each of the two air chambers having at least one opening, so that when opened for both air chambers openings when blowing air into the one air chamber, an air flow over the inner material layer and the hand of the glove wearer on the inner material layer of the second air chamber up to their can form the outlet opening. In this embodiment of the glove according to the invention, the at least second opening or the at least one opening of the second air chamber is preferably in the region of the end of the inner hand part, in particular if the at least first opening of the optionally first air chamber is arranged correspondingly on the upper hand part.

However, the desired air circulation does not necessarily have to be accomplished by the presence of at least a second opening, for example when the opening into which the glove-holder inserts his hand may serve as such at least a second opening.

The embodiment described above is particularly advantageous for operations in summer, since outside air can reach the hand with open valves and the cooling of the hand is achieved. In this case, it may also be appropriate to form the at least one opening such as a grille for receiving "wind", in particular when the at least one opening is arranged on the upper hand part of the glove.

In the warm season, it is desirable to be able to lower the body temperature, wherein heat dissipation to the environment is desirable. If it is not possible to dissipate heat sufficiently through conduction or heat flow, the body will use evaporation and in this case the result will be sweat. In order to be able to ensure the well-being of the body, it is advantageous to keep away the moisture thus formed, as is effected by the use of a semipermeable membrane (5) in combination with the air chamber according to the invention.

As can be seen from the foregoing, the glove of the invention is particularly suitable for outdoor activities such as winter sports, especially skiing, snow-mobile, cross-country skiing, Nordic walking but also for other sports, such as hiking, hiking, climbing, etc. However the glove of the invention is not limited to these sports, but may in particular preferably in the last-presented embodiments are also used for summer sports, especially in those in which a cooling or ventilation of the hand is desired.

In particular, when performing winter sports, such as skiing or snowboarding, it is advantageous if the glove includes an outer layer of material, such as shell material, which protects the glove or the hand of the wearer against external influences such as impacts or extreme weather. In a further preferred embodiment of the glove according to the invention, the latter therefore has, as the outer material layer, an insulation or insulation layer, which preferably consists of a substantially weather-resistant and possibly impact-resistant material or has corresponding regions. Corresponding materials are known to the person skilled in the art and include, for example, plastics and pressure-resistant elements made from other materials.

Furthermore, the air chamber according to the invention as described above and explained in the following embodiment is basically used in equipment intended for at least temporary covering of body parts, in particular articles of clothing, blankets, sleeping bags and other clothing suitable for accommodating extremities. In this regard, the present invention also relates to a piece of equipment containing an air chamber according to the invention and which, as described above, provides an opening for the admission of air.

The items of equipment according to the invention are, in particular, clothing, in particular for upper extremity gloves, for lower extremities socks, shoes, boots, trousers, underwear, for the head cap, cap, cap, mask, and for the torso jacket and coat.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

Show it:

Fig. 1 is a plan view of a glove according to the invention.

2 shows a section through an air chamber with several layers of material.

Fig. 1 shows a schematic representation of a glove (1) with an integrated in the upper hand part of the glove air chamber (2), which is indicated for simplicity by means of an open line. Furthermore, the glove (1) in a conventional manner a Opening for importing the hand, an area for housing the palm, not shown, and an area for housing the finger, also not shown. The glove (1) is provided in the following case for skiing or snowboarding, but it may of course also be another sports glove or a glove for any other function as well as a street or fashion glove.

In the case of the glove (1) according to FIG. 1, a first opening (8) and optionally a second opening (10) are provided. In the present case, the air chamber (2) extends over the entire upper hand part of the glove. By the at least one opening (8) in the air chamber (2) injected breath the upper hand and the fingers within the glove (1) are heated by the formation of a "heat pad" or protected from the cold by the insulating layer thus obtained.

Furthermore, it can be seen that the at least one opening (8) is provided with an element (9) for closing the at least one opening (8), which in the present case is designed as a valve. In a manner not shown, a membrane may be disposed in the valve to prevent the ingress of moisture into the interior of the glove. By blowing over the valved at least one opening (8) in the air chamber (2) a heat air cushion is generated, which keeps the hand warm even after the warm air has been blown in and during the sport operation or isolated from the cold, whereby the up to the The problem of cold hands during exercise is nowadays being alleviated in all gloves.

In contrast to the present representation, an air chamber may alternatively or additionally also be arranged on the inside of the hand with an opening (10) which can be filled with warm respiratory air.

As shown in the illustration of Fig. 1 is preferably attached to the glove finishing tape, approximately where usually a wristwatch is worn, the at least one opening (8) and the at least second opening (10). It is not shown here that the respective at least one opening (8) or at least the second opening (10) does not have to open directly into the air chamber, but is optionally connected by a suitable line to the air chamber.

In contrast to the present illustration, the glove (1) can also be designed with only two finger parts, ie as a mitten or mitten. Fig. 2 shows a section of an air chamber (2) according to the invention, which consists of several layers of material. It is understood by those skilled in the art that the air chamber (2) is usually designed so that the final material layers, even in the case that no air is blown, not directly to each other, and they could possibly "stick together" due to possibly injected moisture but that for example by the use of "spacers" a possible clinging or "sticking together" of the material layers can be avoided. Such "spacers" may include, for example, materials such as foam or nonwoven or sponge rubber. An air chamber (2) according to the invention essentially comprises an outer material layer (3) made of a woven and / or knitted fabric or plastic film, which is substantially impermeable to air, a cavity (4) for receiving the respiratory air, an inner material layer (5), for example from a semipermeable membrane, and optionally an additional material layer (6) of a woven and / or knitted fabric, for example a nonwoven fabric. In the case of a semipermeable membrane, the inner material layer (5) can be formed, for example, from polytetrafluoroethylene (PTFE), in particular from Gore-Tex. However, other materials come into consideration, which have air-permeable properties. Alternatively, the inner material layer (5) is substantially impermeable to air, if no air circulation with the palm area is desired. Materials that can be used in particular for the design of the inner material layer and possibly further subsequent material layers of the air chamber can also be found in German Utility Model DE 20 2005 008 041.
