Abstract

The invention concerns a shoe, in particular a sports shoe, with a sole including an underfoot part, and with an upper part. In order to improve the heat-transfer properties in the underfoot zone, the invention proposes that a closed refrigeration circuit containing a refrigerant is fitted in the sole. The energy necessary to compress the refrigerant is obtained from the reciprocating motion of the foot when the wearer of the shoe walks or runs.

Description

Beschreibung description
Schuh, insbesondere SportschuhShoe, in particular sports shoe
Die Erfindung betrifft einen Schuh mit einer ein Fußbett ent¬ haltenden Laufsohle und einem Schaftteil.The invention relates to a shoe with an outsole containing a footbed and a shaft part.
Im fortwährenden Bestreben, insbesondere im Freizeitbereich Schuhe zu schaffen, die den tatsächlichen Bedürfnissen ange¬ paßt sind, werden verschiedene Wege beschritten. Die wesent¬ lichsten Ziele bestehen darin, dem Fuß einen optimalen Halt zu geben, ohne daß hierdurch Bänder und Sehnen mehr als not¬ wendig beansprucht werden. So sind beispielsweise Schuhe be¬ kannt, deren Fußanpaεsung durch in einen Innenschuh einzupum¬ pende Luft oder aufschäumbares Material gewährleistet werden soll. Andere Konstruktionsmerkmale schaffen eine erhöhte me¬ chanische Stabilität bzw. Elastizität, was sowohl durch spe¬ zielle Materialauswahl als auch durch Dä pfungε- und/oder Torsionεkörper, die zusätzlich in die Schuhsohle eingebracht werden, bewirkt wird.In the constant endeavor, in particular in the leisure sector, to create shoes which are adapted to the actual needs, various paths are taken. The most important goals are to give the foot an optimal grip without the ligaments and tendons being more than necessary. For example, shoes are known whose foot adjustment is to be ensured by air to be pumped into an inner shoe or by foamable material. Other design features create increased mechanical stability or elasticity, which is brought about both by special material selection and by damping and / or torsion bodies which are additionally introduced into the shoe sole.
Ungelöst ist jedoch bisher das Problem, wie die bei Bewegung im Schuh auftretende Wärme abgeführt werden kann. Als unzu¬ reichend haben sich Belüftungslöcher erwiesen, die meist in¬ nen am Mittelfußbereich des Schuhes angeordnet sind. Daß das Wohlbefinden des Schuhträgers, insbesondere bei sportlichen Aktivitäten, die hohe Energieleiεtungen erfordern, erheblich davon abhängt, wie gut die Wärmeabfuhr auch im Fußbereich ist, ist unbestritten. Das Problem der unzureichenden Wär¬ meabführung vergrößert sich bei solchen sportlichen Betäti¬ gungen, die auf heißen Asphaltbelägen stattfinden.So far, however, the problem of how the heat generated during movement in the shoe can be dissipated has not been solved. Ventilation holes, which are usually arranged in the midfoot area of the shoe, have proven to be inadequate. It is undisputed that the well-being of the shoe wearer, particularly in sporting activities that require high energy levels, depends significantly on how good the heat dissipation is in the foot area. The problem of inadequate heat dissipation increases in the case of such sports operations that take place on hot asphalt surfaces.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Schuh zu schaffen, der ohne hohen konstruktiven Aufwand eine einfa¬ che und ausreichend wirksame Wärmeabfuhr bzw. Kühlung gewähr- leistet. Die hierzu verwendeten baulichen Mittel sollen dar¬ über hinaus so dimensioniert sein, daß der nach dem Stand der Technik bekannte Schuh in seiner äußeren Formgestaltung un¬ verändert bleibt.It is therefore an object of the present invention to provide a shoe which allows simple and sufficiently effective heat dissipation or cooling without high structural outlay. accomplishes. The structural means used for this purpose should also be dimensioned such that the shape of the shoe known from the prior art remains unchanged.
Diese Aufgabe wird durch einen Schuh, insbesondere Sportschuh gelöst, bei dem in der Laufsohle ein geschlossener ein Kühl¬ mittel enthaltener Kältemaschinenkreislauf derart angeordnet ist, daß an der dem Fuß zugewandten Fußbettεeite ein als Ver¬ dampfer wirksamer weitgehend- inelastischer erster Raum, ein im Fersen- und/oder im Vorderfußbereich als Kompressor wirk¬ samer zweiter elastischer- Hohlraum und ein als Kondensator wirksamer dritter Raum vorgesehen und miteinander über Ein¬ wegventile und/oder Sinterdrosseln verbunden sind. Der Grund¬ gedanke der vorliegenden Erfindung beruht darauf, die Ver¬ dampfungskühlung ohne Zufuhr weiterer Energie auszunutzen. Die zur Kompression des Kühlmittels notwendige Energie, die in großindustriell üblichen Kältemaschinen, aber auch Kühl¬ schränken in Form elektrischer Energie zum Betrieb einer Pumpe bereitgestellt wird, wird bei dem Schuh aus der Arbeit gewonnen, die der Schuhträger beim Gehen oder Laufen leistet. Energielieferant des Kältmaschinenkreiεlaufeε ist daher ein im Fersen- und/oder Vorderfußbereich wirksamer elastischer Hohlraum, der beim Auftreten zusammengedrückt wird, womit das Auspressen des Kühlmittels über ein Einwegventil oder eine Drossel in einen weiteren als Kondensator wirksamen Hohlraum einhergeht. Zur Kälteerzeugung wird folgender physikalische Effekt ausgenutzt. Wenn man eine bestimmte Gas- oder Flüssigkeitsmenge rasch komprimiert, steigt ihre Temperatur, ohne daß weitere Wärme zugeführt wird, da durch die Kompression die innere Energie des gasförmigen oder flüssigen Kühlmittels erhöht wird. Besitzt das komprimierte Kühlmittel eine Temperatur, die über der Umgebungstemperatur liegt, wird Wärme abgegeben, so daß der Wärmegehalt des Kühlmittels ge- - ringer ist. Läßt man das Kühlmittel adiabatisch unter Ar¬ beitsleistung entspannen, so erniedrigt sich die Temperatur weiter, d.h., die Kühlmitteltemperatur sinkt zwangsläufig un¬ ter die Umgebungstemperatur mit der Folge, daß im Verdampfer Wärme benötigt wird, die dem Fußbett des Schuhes entzogen wird. Bei abermaligem Ansaugen des Kühlmittels aus dem Ver¬ dampfer in den Kompressorraum schließt sich der geschilderte Kältemaschinenkreislauf.This object is achieved by a shoe, in particular a sports shoe, in which a closed refrigerating machine circuit containing a coolant is arranged in the outsole in such a way that on the foot bed side facing the foot there is a largely inelastic first space effective as an evaporator, one in the heel - and / or in the forefoot area as a compressor effective second elastic cavity and a third space acting as a condenser are provided and are connected to one another via one-way valves and / or sintering throttles. The basic idea of the present invention is based on utilizing the evaporation cooling without supplying further energy. The energy required to compress the coolant, which is provided in refrigeration machines customary in large industrial scale, but also in the form of electrical energy for operating a pump, is obtained in the shoe from the work that the shoe wearer does when walking or running. The energy supplier of the refrigeration cycle is therefore an elastic cavity effective in the heel and / or forefoot area, which is compressed when it occurs, which is accompanied by the squeezing out of the coolant via a one-way valve or a throttle into a further cavity which acts as a condenser. The following physical effect is used to generate cooling. If one compresses a certain amount of gas or liquid rapidly, its temperature rises without additional heat being added, since the compression increases the internal energy of the gaseous or liquid coolant. If the compressed coolant has a temperature which is above the ambient temperature, heat is emitted so that the heat content of the coolant is lower. If the coolant is allowed to relax adiabatically under operating power, the temperature lowers further, ie the coolant temperature inevitably drops below the ambient temperature, with the result that heat is required in the evaporator, which is removed from the footbed of the shoe. When the coolant is sucked in again from the evaporator into the compressor space, the refrigeration cycle described closes.
Wie prinzipiell auch aus Kühlanlagen bekannt, kann der zuvor geschilderte Effekt noch verεtärkt werden, wenn das Kühlmit¬ tel im komprimierten Zustand flüssig wird und bei der Ent- . Spannung verdampft, da dem Fußbett dann zusätzlich noch die zur Verdampfung notwendige Wärme entzogen wird. Kühlmittel dieser Art sind prinzipiell bekannt, z.B. Ammoniak oder ver¬ schiedene Fluorkohlenwasserεtoffe. Nach oben geschildertem Kreislauf richten sich auch die Anforderungen an das Schuh¬ sohlenmaterial. Im Übergangsbereich vom Fußbett zu dem ersten als Verdampfer wirksamen Raum muß gewährleistet sein, daß die im Fußbett vorhandene Wärme rasch in den Verdampferr um abgeleitet wird. Weiterhin müssen der Ort und die Lage bzw. Geometrie des zweiten elastischen Hohlraumes so beschaffen sein, daß die beim Auftreten und Abheben des Fußes gewinnbare Pumpenergie optimal genutzt wird. Hierbei ist zu berücksichten, daß insbesondere beim Laufen die Zeitspanne, während der Kompressionsarbeit verrichtet wird, weitaus ge¬ ringer ist als die Zeit, die zur Materialentspannung zur Ver¬ fügung steht. Schließlich verbessert sich die Funktionsfä- higkeit des Kältemaschinenkreislaufes mit der optimierten Wärmeabfuhr im Kondensator.As is also known in principle from cooling systems, the effect described above can be further enhanced if the coolant becomes liquid in the compressed state and during removal. Voltage evaporates because the footbed is then also extracted from the heat necessary for evaporation. Coolants of this type are known in principle, e.g. Ammonia or various fluorocarbons. The requirements for the shoe sole material also apply to the cycle described above. In the transition area from the footbed to the first space acting as an evaporator, it must be ensured that the heat present in the footbed is rapidly dissipated into the evaporator. Furthermore, the location and the position or geometry of the second elastic cavity must be such that the pump energy that can be obtained when the foot appears and is lifted is optimally used. It must be taken into account here that, especially when running, the time span during which the compression work is carried out is far less than the time available for material relaxation. Finally, the functionality of the refrigeration cycle improves with the optimized heat dissipation in the condenser.
Prinzipell ist jedeε Kühlmittel der folgenden Gruppe verwert¬ bar: Ammoniak, Schweifeldioxid, Kohlendioxid, Methylchlorid, Methylenchlorid, Ethylchlorid, Ethyldichlorid, Difluorchlor- methan, Monofluortrichlormethan, Trifluormonochlormethan, Difluormonochlormethan, Trichlortrifluorethan und Dichlorte- trafluorethan. Die letztgenannten Stoffe sind auch als Freon bekannt. Mit angesprochen sind jedoch auch all diejenigen Stoffe, die in geeigneter Weise die genannten Fluor ohlenwas- serstoffe als Kühlmittel ersetzen können.In principle, each coolant from the following group can be used: ammonia, sulfur dioxide, carbon dioxide, methyl chloride, methylene chloride, ethyl chloride, ethyl dichloride, difluorochloromethane, monofluorotrichloromethane, trifluoromonochloromethane, difluoromonochloromethane, trichlorotrifluoromethane and trichloro-trifluoromethane and dichloromethane. The latter substances are also called Freon known. However, all those substances are also addressed which can appropriately replace the hydrofluoric hydrocarbons mentioned as coolants.
Nach einer weiteren Ausgestaltung der Erfindung ist der Kon¬ densatorraum im wesentlichen an der Außenperipherie der Sohle und/oder an der Unterseite der Sohle angeordnet oder er besitzt zur Sohlenaußenseite gerichtete Lüftungskanäle. Der Kompressionsgrad ist bei dem genannten Schuh im wesentlichen durch die Art der sportlichen Betätigung des Schuhträgers vorgegeben, so daß die Kompressionsarbeit eine weitgehend bei der Schuhkonstruktion unbeeinflußbare Größe anzusehen ist. Hingegen führt eine verstärkte Wärmeabfuhr vom Kondensator¬ raum zu einer erhöhten Erniedrigung der inneren Energie des Kühlmittels, die anschließend im Verdampferraum nutzbar ge¬ macht werden kann. Daher kommt der Wärmeabfuhr vom Kondensa¬ torraum eine wesentliche Bedeutung zu.According to a further embodiment of the invention, the condenser space is arranged essentially on the outer periphery of the sole and / or on the underside of the sole, or it has ventilation channels directed towards the outside of the sole. The degree of compression in the shoe mentioned is essentially predetermined by the type of sporting activity of the shoe wearer, so that the compression work can be seen as a parameter largely uninfluenced by the shoe construction. In contrast, an increased heat dissipation from the condenser chamber leads to an increased lowering of the internal energy of the coolant, which can subsequently be used in the evaporator chamber. Therefore, the heat dissipation from the capacitor space is of major importance.
Nach einer weiteren Ausgestaltung der Erfindung erstreckt sich der als Verdampfer wirksame erste Raum im wesentlichen vollständig über die gesamte Fußbettfläche, um ein Optimum an Wärmeübergangszonen zu erzeugen.According to a further embodiment of the invention, the first space, which acts as an evaporator, extends essentially completely over the entire footbed area in order to produce an optimum of heat transfer zones.
Vorzugsweise sind die genannten Kammern (Verdampfer, Kompres¬ sor und Kondensator) sowie deren Verbindungεleitungen mit ei¬ ner gegen das Kühlmittel inerten Auskleidung versehen, die Korrosionen erhindern soll.The above-mentioned chambers (evaporator, compressor and condenser) and their connecting lines are preferably provided with a lining which is inert to the coolant and is intended to prevent corrosion.
Weiterhin vorzugsweise besteht die Laufεohle aus einem ein- oder mehrteiligen Kunststoff, insbesondere Polyurethan, der sich leicht im Spritzgießverfahren verarbeiten läßt.Furthermore, the outsole preferably consists of a one-part or multi-part plastic, in particular polyurethane, which can easily be processed by injection molding.
Schließlich besitzt nach einer Weiterbildung der Erfindung der Kühlkreislauf eine wiederverschließbare Öffnung, die es erlaubt, das Kühlmittel im Bedarfsfall zu entnehmen bzw. Kühlmittel nachzufüllen. Nach einer weiteren Ausgestaltung der Erfindung sind die Ein¬ wegventile oder Drosseln einstellbar, um den Kühlmitteldurch¬ fluß bei Bedarf erhöhen oder erniedrigen zu können. .Finally, according to a further development of the invention, the cooling circuit has a reclosable opening, which allows the coolant to be removed when necessary or the coolant to be refilled. According to a further embodiment of the invention, the one-way valves or throttles can be adjusted in order to be able to increase or decrease the coolant flow as required. ,

Die Kältemaschine besitzt folgende wesentliche Beεtandteile: Einen Verdampfer 10, einen Verdichter 11, einen Verflüεεi- ger 12 sowie eine Droεseleinrichtung 13.The refrigeration machine has the following essential components: an evaporator 10, a compressor 11, a condenser 12 and a dropper device 13.
Durch den im Verdampfer 10 bei niedrigem Druck und Raumtempe¬ ratur aufgenommenen Wärmestrom W]_ wird flüssiges Kältemittel verdampft. Der entstehende Dampf wird von dem Verdichter II angesaugt und komprimiert, so daß im Verflüεsiger 12 eine höhere Temperatur als die Umgebungstemperatur vorliegt; dasLiquid refrigerant is evaporated by the heat flow W ] _ taken up in the evaporator 10 at low pressure and room temperature. The resulting steam is sucked in and compressed by the compressor II, so that a higher temperature than the ambient temperature is present in the condenser 12; the
Kühlmittel befindet sich in flüεsigem Zustand. Der Verflüεεi- ger 12 gibt Wärme W2 an die Umgebung ab. Wird nun das Kühl¬ mittel durch die Drosεel 13 auf einen niedrigeren Druck im Verdampfer 10 entspannt, erniedrigt sich die Temperatur des Kühlmittels, was durch die bei der Verdampfung des Kühlmit¬ tels notwendige Verdampfungswärme noch erhöht wird. Die niedrigere Temperatur des Kühlmittels im Verdampfer 10 wird durch Wärmeaufnahme von außen, nämlich aus dem Fußbett (Wärmemenge W^) wenigstenε teilweise ausgeglichen.The coolant is in a liquid state. The condenser 12 releases heat W 2 to the surroundings. If the coolant is now expanded to a lower pressure in the evaporator 10 by the throttle 13, the temperature of the coolant lowers, which is further increased by the heat of evaporation necessary for the evaporation of the coolant. The lower temperature of the coolant in the evaporator 10 is at least partially compensated for by heat absorption from the outside, namely from the footbed (heat quantity W ^).
Die Umsetzung dieses Kaltdampf-Verdichtungsverfahrens auf einen Schuh iεt in Fig. 2 skizziert. Diese zeigt eine Schuh¬ sohle 14 im Querschnitt; der Schaft bzw. das Obermaterial 15 sind nur angedeutet. Unmittelbar an das Fußbett 16 anschlie¬ ßend liegt ein erster Raum 17, der als Verdampfer 10 wirksam wird. Mit dem ersten Raum 17 ist ein elastischer Hohlraum 18 über eine Leitung 19 verbunden, die zur Vermeidung des Rück¬ flusses ein entsprechendes Einwegventil besitzt. Von dem elastischen Hohlraum 18 führt eine ebenfalls mit einem Ein¬ wegventil ausgestattete Leitung 20 zu einem dritten Raum 21, der als Kondensator wirkt. Dieser dritte Raum 21 besitzt eine möglichst große Außenoberfläche, worüber ein optimaler Wär¬ meaustausch mit der Umgebung möglich ist. Wie oben beschrie¬ ben, erfüllen der elastische Hohlraum 18 die Funktion des Verdichters 11, der Raum 21 die des Verflüssigers 12 und der mit dem Raum 21 über eine eine nicht dargestellte Drossel aufweisende Leitung 22 verbundene erste Raum 17 die des Ver¬ dampfers 10. The implementation of this cold vapor compression process on a shoe is outlined in FIG. 2. This shows a shoe sole 14 in cross section; the shaft or the upper material 15 are only indicated. Immediately adjacent to the footbed 16 is a first space 17, which acts as an evaporator 10 becomes. An elastic cavity 18 is connected to the first space 17 via a line 19, which has a corresponding one-way valve to avoid backflow. A line 20, which is also equipped with a one-way valve, leads from the elastic cavity 18 to a third space 21, which acts as a condenser. This third space 21 has the largest possible outer surface, by means of which an optimal heat exchange with the surroundings is possible. As described above, the elastic cavity 18 fulfills the function of the compressor 11, the space 21 that of the condenser 12 and the first space 17 connected to the space 21 via a line 22, which does not have a throttle, that of the evaporator 10.
