cooling suit.

[0001] The present invention relates to a body suit for cooling the body to work and recreational and/or at high humidity at high outside temperatures that is to say, in humid, pushing weather.

[0002] Many activities in the professional world or even with armies and protective force it needs to take place under more severe operating conditions, notably at elevated outside temperatures and/or high humidity. The produce work at high outside temperatures, in particular when the humidity is high in addition, the operation performance reduced striking. Construction workers on construction sites in hot climate zones are exhausted after a short time. Firefighters, in fires are in use, or rescue forces, have to intervene in the event of disasters in hot zones in, suffer from the large heat and come soon to their limits by the performance. Another example are [...]jet-powered fighter planes during the preparatory and pilots and crew from. Bis in the benefits of the on-board air conditioning of the aircraft come, they wait in a standby mode often carry out preparatory work on their insert or outside the aircraft. To quickly to be operational, but they bear the employment clothing already that is to say, a full aviators and/or [...]. This is difficult and allows hardly a body respiration. Very rapidly one goes into the sweating and long phases at high outside temperatures therein and/or high humidity outdoor are for torture. Also pilots and crew members of helicopters, as well as other, however, transport and special airplanes -are often high temperatures and/or during the pre-and exposed to a high humidity [...] account of their special and must employment clothes, the incentives for is predestined, bring about a heat build-up. This is particularly the case during extreme inserts, in which the aircraft and thus their air-conditioned cars-if these have to be air-conditioned to leave are at all. But not only flight crews, including those of ships and land vehicles, which operate in hot climates for special inserts, face the problem of high temperatures and/or the high humidity faced. In Principle whose performance is reduced at high prevailing temperatures and/or at high humidity prominent.

[0003] Precisely insert-specialists of fire brigades, hazardous substance-squads or special units, for disarming unexploded ordnance and explosive bodies are sent out approximately, suffer particularly, when the outside temperatures and/or the air humidity are high and they have to work with corresponding special protective clothing under full protection. But professional groups, the work under extreme conditions, such as tunnel farmer, mine buddy or spout in the range of blast furnaces, or in hot climates or in hot desert areas workers to oil wells on drilling platforms are often exposed to high temperatures and be correspondingly more stifling air and claimed. The same applies to all land and Forest Worker and seamen, the working in the open air or in rooms and areas have to carry elevated temperature and/or humidity, their performance and well-being directly dependent on the prevailing temperature and the current air humidity. Finally this issue cuts and recreational activities. Gardening wherein more breeding heat and/or humid weather weld-rubbing and are very tedious, but also outdoor sporting activities, ranging from walks, hikes, of becoming an ordeal run training to games and cycling are then often be omitted or, when the weather is too hot or to oppressive.

[0004] so far there is no good solutions for the cooling of the body of working and employment personnel, when in hot ambient temperature and/or high humidity required to be active. The known proposals include usually electrically operated cooling systems, for example, protective suits with built-in electrical mini-fans, or suits with liquid cooling, wherein the cool liquid through channels in the protective suit circulates and is cooled by a cooling aggregate flows externally over a cycle and therein. This is a function of electric current to its operation, or at least from an internal combustion engine. Therefore a permanent hose connector having such a relatively heavy conditionally This solution external aggregate.

[0005] The known solutions are all little practicable, cumbersome in the handling and expensive. They Close many components a, some of which are difficult and they need for their use an external energy source. The many components in the high cost of such a strike out Whereas cooling suit lower. The operation and management of these are also not be described as particularly easily cooling suits.

[0006] In view of this situation it is the task of the present invention, to create a cooling suit for everyone, hot ambient air and/or high humidity in the work or actively wants to be or must, wherein this cooling suit easily, efficiently, simply operable, inexpensive and fool-proof in its function in the purchase and is to be in the maintenance.

[0007] This problem is solved by a cooling suit, consisting of a suit for legs, torso and arms, the branching from an outwardly opening includes inwardly Hose Multi-orifice gas channels, as well as an associated compressed gas cylinder for carry or an associated stationary Hose output hose with the coupling piece, to the pressure vessel for connecting a roll, wherein a valve with adjusting wheel to said cylinder or at the suit is present, for the metered delivery of relaxed gas from said cylinder or the stationary pressure vessel into said gas channels.

[0008] Unlike all the currently available air powered body cooling systems, the work of warm and/or humid air from the environment with the amount of sucked in, this is operated with a dry cooling suit, compressed gas is carried in a pressurized-gas cylinder. Strategically flat gas channels placed the dry and direct cold gas after expansion to the different distinct sweating places of the body, whereby a more efficient and of physiologically acceptable cooling effect is achieved. The cooling by natural convection will be supported by the system and at the surface by the permanent gas supply over the breathable fabric Welding transported away.

[0009] This cooling suit by reference to the drawings and described below as embodiment disclosed. His function and handling is explanatory work.

It shows:

Fig. 1 : cooling suit viewed from front stage rotation of the, cooling suit arranged on the inside of the outer skin of the flat gas channels with the, the are shown as a broken line, because they are not visible from the outside;

Fig. 2:1 when viewed from the rear the institution of the cooling suit according Fig., cooling suit arranged on the inside of the outer skin of the flat gas channels with the, the are shown as a broken line, because they are not visible from the outside;

Fig. 3: Den cooling suit of obliquely rear view of the carrier, with a compressed gas cylinder in a carrier carrying at the back, and the hose connection to the gas channels in the suit.

[0010] 1 on a carrier is shown in Fig. cooling suit The, wherein this is represented as viewed from the front. The textile suitcooling suit is a, here in the form of a so-called combi-suit 1 that is to say, in one piece with the legs of the pants for torso and arms carried out and an upper part. Zum easy entry and an exit for the putting on or taking off is equipped with a slide fastener 16 1 the suit, which extends from the step to completely upwards to the collar. As specificity is 1 on the inner side of its outer layer with different gas channels 3-6 these Garment provided. Their course is here shown as a broken line, because the gas channels 3-6 from the outside will not be seen. This textile channels carried out for example as a flat 3-6 are gas channels, are provided with a gas-impermeable layer the inside or outside, and 1 are mounted on the inside of the suit, by laminating, welding, or they are sewn onto the inside sewn to the inner side of the suit or 1.

[0011] In the shown example this gas channels at a channel system 2 with clutch begin branching out Hose as 3-6, in the waist region protrudes laterally out of the suit the 1. However, it is clear that these Hose elsewhere could project from the suit, for example, in the chest region. From one gas channel 6 leads into a ring by the Hose, which remains comprises the hip, which ring 16 open in the front region in order to open the slide fastener. From that ring 3 downwardly and a respective gas channel, branches off from the waist region on the outer side the length of the leg is guided and leads piece far Femoral Orthopaedic a downwardly onto the rear side of the trouser leg further below, so as to terminate in the finally knee cave range.

[0012] as units of 2 Fig., which said carrier of the 1 when viewed from the rear shows cooling suit according Fig., open itself the further course of the gas channels. From ring, surrounds the hip, branch in gas channel 15 extends upwardly from the range of the cross and into a further along the spinal column, annularly applied gas channel 5, which surrounds the neck and neck of the wearer. Also this ring is open at the front, 1 recognizes how in Fig., so that the continuous slide fastener 16 can be opened. From the ring 16 on the front of the suit two sections extend downwardly and terminate along the slide fastener in the chest region 11 of the carrier. From the annular gas channel 4 over the shoulders 5, branches off a respective gas channel further in the sleeves of said suit ab. These two gas channels 4 extend along the sleeves, preferably on the side of the sleeves, the lie the inside of the arms of the support opposite to. Finally there is one from the ring at the hip from the rear into the center downwardly branching gas channel, the leads downward into the bottom area and terminates in the region of the step 8.

[0013] 2 and 3-6 are all supplied via the gas channels These various Hose by a coupled hose from a compressed gas bottle with related expanded gas therefrom, as the later is clear on the basis of 3 Fig.. The by the depressurization cooled gas, in the simplest case, ordinary air, flows from the 2 is brought into the entire branching Hose to very specific locations and each gas channels-system for the outflow to a part, wherein the remaining gas in the channel system proceeds. This 1 and 2 with arrows leaking out places are entered into the Fig.. It are those locations, at which the body perspires and above all where it can remove heat efficiently. A first outlet opening is located in the region of the cross 15 of the support and on the front side of the ring surrounding the hip in the region of the belly 14 is located in the region of the neck 9 and. A next outlet opening in the region of the breast 4 gas or air channels 11. The, which are guided in the sleeves over the shoulders, in the region of the armpits point 10 on outlet openings, and in the area of the 12 arm joints that is to say, on the inside of the joints, and finally on the side in the front region of the sleeves, the opposite of the inner side 13 of the forearm of the wearer. Precisely interior arm a great deal of heat from the region of the can are discharged 13 of the lower arm, because that is where the blood in strands, veins and vessels circulates, the run close to the major surfaces. In the lower region of the body are arranged in the region of the gas outlets 7 knee caves, and furthermore at the end of the gas channel, which leads along the region of the crotch [...] for 8, where also is arranged an outlet opening. The largest gas duct system prevails in the pressure in the section, before the gas reaches a first outlet opening that is to say, ring, which encloses the hip. After each passage an outlet opening is reduced the gas pressure and is finally in the regions of the lowest knee cavesinterior arms the forearms, as well as in the. This the cooling gas or the cooling air is distributed as desired, against the outer ends of the branching gas duct system towards the outlet openings must be always a little larger, so as to bear the pressure drop Invoice. In the area of the cross is the outlet opening at the smallest sized, because that is where the pressure in the still is greatest gas duct system, and in the region of the forearms are sized larger the outlet openings. This is increasing the pressure drop compensate for, so that depending on the size and design of the outlet ports everywhere approximately equal in number or gas. Air flows out per time. The outlet openings can be formed as slots or as fine perforations in the gas channels 4-6.

[0014] In one variant the gas channel into a number of separated gas channels for certain or can-system for each of the outlet ports be divided, so that therefore the gas pressure in each channel and each outlet opening runs can be operated by the same pressure the same. Then but each separate gas channel are supplied separately with compressed gas from the compressed-gas cylinder must. It can then be fitted with a separate valve and to each tube, so that each outlet port can be operated with an adjustable pressure.

[0015] In another variant the suit can also as a two-piece suit be made from a textile material from pants and jacket. The branching can be connected via an additional hose coupling between Pants and jacket are then gas channels. Both Garments that is to say, independently of one another by such a jacket and pants can also be fitted cooling system that is, a jacket with its own supply hose and one for the for the trousers with also a private supply hose.

[0016] The gas channels are on the inside of the outer layer of the suit [...] 1 as before described. The Garment is equipped with a liner, which covers these gas channels 3-6, so that only said inner liner everywhere contiguous relationship with the wearer. This is of a good skin-compatible, breathable absorbent textile material is prepared and also Welding, for example, from pure cotton or of cotton with only a minor proportion of synthetic fibres. A cotton inside lining makes the Garment comfortably for supporting and furthermore such an inner lining, of the effluent gas to flow through them at the outlet openings, and this protecting itself quite freely along the body and then a path outwardly and flows finally sleeve openings predominately at the suit, at the neck and at the lower ends of the legs outwardly.

[0017] 3 shows the carrier of the rear view of obliquely cooling suit Fig. The. He 21 in a carrier 17 carries at the back with a compressed gas cylinder. This bottle contains compressed air or other suitable 17 for example, 3 kg, dry gas, for example nitrogen, at a pressure of 300 bar for example. For these bottle compressed air contents an energy store 17 and their forms, and it is this energy is used for efficient cooling of the body of the wearer. Through the metered outflow Pamper of the compressed gas or of the compressed air is adiabatically expanded this during the outflow. The is discharged in the form of pressure energy stored in the form of heat to the surroundings, whereby the gas or the experiences a significant slow-down. The in this way completely passively cooled air then flows over the hose coupling 20 in accordance with the cooling gas or gas duct system of said suit and by giving way to the various outlet openings in this gas duct system from. The air or gas takes heat from the body of the wearer in at said locations on. or cools and finely adjustable Mass in physiologically acceptable. The cooling by natural convection will be supported by the system to the surface of the body of the carrier is received and the Welding from the permanent air flowing past or over the breathable fabric of the inside lining and the gas finally outwardly transported away.

[0018] 18 equipped with a valve 17 is pressurized gas bottle The, in several positions by means of an adjusting wheel 24 being separated into two parts that can be snapped. Depending on the degree of opening of the valve 18 flows from the compressed-gas cylinder more or less compressed gas per time is released. The more compressed gas 17, all the greater the cooling effect is in the suit, but the shorter the time is. With a cylinder of compressed gas for example, air at a pressure of from 2 liters volume and 300bar 600 litre can be carried with air. A 3 litres volume contains 600bar even at 900 liter pressure bottle with compressed air. In the lowest open position continuously from the bottle flows about 1 litres of air per minute, so as to obtain a maximum of 10 hours reaches leaking out duration. Higher to 20 litres of air per minute from the bottle can cooling capacity to be based, in which case the time to cool to 30 minutes is reduced. A high-speed cooling function permits the release of air or 40 litres. Cooking per minute. The condition that is intensively cool a body during 15 minutes, when about an insert near a fire is necessary.

[0019] The institution at any time by adjusting the valve 18 can adjust the cooling power on a measure, the him is pleasantly. It is clear that this valve 18 with setting wheel 17 can be arranged directly on the bottle 24 as elsewhere, for example on a belt carried with the suit, or front 12 on the carrier device, so that the adjusting wheel 24 and also visible is in reach. In this case a hose leads from the bottle 24 to the valve 17, and from the valve 2 the pressure bottle 17 can optionally thereafter for Hose. Whereas be fitted with a manometer, what can be drawn which conclusions about the current, so that there is always white, how long you still has over an intact cooling function. It is understood that the minimum and maximum cooling duration is dependent on the pressure prevailing therein compressed gas contents and from the. 2 litres capacity or even more gas or with pressure bottle A air content offers still longer cooling periods.

[0020] in order to have to carry as little as possible weight, the pressurized-gas cylinder 17 is preferably made of lightweight material, for example based on carbon reinforced fibers and provided with an airtight coating. Such are bottles fair marketable quality. Whereas custom-made carrier device is insertable into a 17 the pressurized-gas cylinder 21, with which it can be supported very comfortably on the back. To this end the supporting device is equipped with two wide shoulder- carrier loops 22,23 and with a lap belt is also easily bend the carrier 21 can. This carrier device, or it can lie on the side and also genuflect, to perform jobs. Compact and easily and it disturbs when performing its The device is little or no work. With the entire system, due to its low weight of the carrier must carry an extra of about 5 kg with it just, therefor it can operate in perfect body-climatic conditions. The weighs about 1.5 kg alone Garment. The 2 liter pressure bottle for example, a weight 21 together with a carrying device brings of just a total of less than 6.5 kg on the scales.

[0021] the pressurized-gas cylinder Will or. Compressed air bottle during insertion of empty, so it can be replaced by a filled with a few handles. This the hose connection is solved at the 2 Hose, the pressure bottle 17 17 21 removed and a filled pressure bottle from the carrier device is used. Their hose 19 is coupled to the 1 and 2 is again ready for operation at the already Hose cooling suit the cooling system. As A hose coupling is a commercially available quick connector for gas hoses, for example a pivotal coupling for pressureless coupling ora Linear clutch.

[0022] This cooling suit can be used not only with a directly but also backed pressure bottle, but existing pressure vessel with compressed air from a separately established pressure bottle or a separately, particularly then, when the user sitting on seats carry out their activities, in helicopters or aircraft and for riding about for flies or [...]ride along in vehicles of all types and. In this manner he used is suitable to use for example in helicopters, transport aircraft, tanks, civil and military vehicles, ships, U-boats, etc., in which case the relaxed compressed air from a pressure bottle or a stationarily installed pressure vessel based can be provided. It can then be connected to a large pressure vessel also more cooling suits collectively, which can be recharged from an on-board compressor, in which case the pressure vessel can be cooled actively by a cooling device separately, for example to the normal internal temperature of the relevant aircraft, vehicle or other space. This cooling suit therefore offers a great relief of all kinds for a great many members of their working conditions and it forces quite crucial boosting their working efficiency. He, however, can also be used by each private individual, for any work or outdoor sports activities, whenever the prevailing temperatures are high or leads to a high humidity stifling weather conditions.
