Abstract

There is a sports shoe with a sole (4) and an inflating device which is arranged under a convex part of the foot (3) and delimits a compression chamber (16) with a chamber body (1) as well as a chamber roof (14), the compression chamber having an inlet opening (17) and an outlet opening (18). It is desirable to improve the effect of the inflating device by minimizing the clearance space in the compression chamber. This is accomplished by forming the compression chamber (16) as a semi-lentil-shaped (dished) bowl which is conformed to fit the convex contour of the region of the foot (3) loading it and by having the inlet opening (17) as well as the outlet opening (18) arranged in the central area of the chamber (16). Since, on compression, the chamber cover will hug the bottom of the compression chamber, it is possible to produce a positive pressure commensurate with the down-stepping force applied.

Description

Die Erfindung betrifft einen Sportschuh mit einer Sohle, die mit zur Aufnahme von Luft unter Überdruck dienenden Kammern und einer daran angeschlossenen fußbetätigten pneumatischen Ladevorrichtung versehen ist, die unter einem von einem balligen Fußbereich zu belastenden Bereich eines Sohlenteiles angeordnet ist und mit einem Kammerkörper sowie einem dem Sohlenteil zugeordneten Kammerdach einer Stauchkammer begrenzt, die über eine Einlaßöffnung sowie ein Einlaßventil mit der Außenatmosphäre und über eine Auslaßöffnung sowie ein Auslaßventil mit den Kammern verbunden ist.The invention relates to a sports shoe with a sole, which is provided with chambers for receiving air under positive pressure and a foot-operated pneumatic charging device connected to it, which is arranged under an area of a sole part to be loaded by a spherical foot area and with a chamber body and one The chamber roof assigned to the sole part is delimited by a stuffer box, which is connected to the outside atmosphere via an inlet opening and an inlet valve and to the chambers via an outlet opening and an outlet valve.

Bei einem bekannten (DE-OS 30 31 818) Sportschuh die­ser Art ist die Stauchkammer im senkrechten Quer­schnitt im wesentlichen rechteckig. Die Einlaßöffnung und die Auslaßöffnung sind an im wesentlichen verti­kalen Wandungsbereichen dicht unter dem Kammerdach angeordnet. Wenn die Ladevorrichtung betätigt wird, indem das Kammerdach und der Kammerkörper unter Ver­ringerung des Stauchkammervolumens gegeneinander ge­drückt werden, so bleibt auch bei starkem Druck ein relativ großer Totraum übrig. Dieser verbleibende Totraum vermindert die Leistungsfähigkeit der Lade­vorrichtung, weil sich nur relativ geringe Drücke er­reichen lassen. Wegen des unvermeidbaren großen ver­bleibenden Totraumes muß eine relativ große Höhe der Stauchkammer, d.h. ein großer Hubweg der Ladevorrich­tung in Kauf genommen werden, was mit Nachteilen bei der Benutzung des Sportschuhes verbunden ist.In a known (DE-OS 30 31 818) sports shoe of this type, the stuffer box is essentially rectangular in vertical cross section. The inlet opening and the outlet opening are arranged on substantially vertical wall areas close below the chamber roof. If the loading device is actuated by pressing the chamber roof and the chamber body against one another while reducing the stuffer box volume, a relatively large dead space remains even under high pressure. This remaining dead space reduces the performance of the loading device because only relatively low pressures can be achieved. Because of the inevitable large remaining dead space, a relatively large height of the stuffer box, i.e. a large stroke of the loading device can be accepted, which is associated with disadvantages when using the sports shoe.

Eine Aufgabe der Erfindung ist es daher, einen Sport­schuh der eingangs genannten Art zu schaffen, bei dem eine verbesserte Wirkung der Ladevorrichtung unter Minimierung des Totraumes der Stauchkammer gegeben ist. Der erfindungsgemäße Sportschuh ist, diese Auf­gabe lösend, dadurch gekennzeichnet, daß die Stauch­kammer als halblinsenförmige, der Balligkeit des be­lastenden Fußbereiches angepaßte Mulde ausgebildet ist und die Einlaßöffnung sowie die Auslaßöffnung im Mittenbereich der Kammer angeordnet sind.An object of the invention is therefore to provide a sports shoe of the type mentioned, in which an improved effect of the loading device is given while minimizing the dead space of the stuffer box is. The sports shoe according to the invention is solving this problem, characterized in that the stuffer box is designed as a semi-lenticular trough which is adapted to the crowning of the stressful foot region and the inlet opening and the outlet opening are arranged in the central region of the chamber.

Durch die halblinsenförmige Gestalt der Stauchkammer ist bei zusammengedrückter Stauchkammer der Totraum minimiert, da sich das Kammerdach dem Grund der Stauchkammer anschmiegt. Dadurch läßt sich ein dem auftretenden Kraftstoß entsprechender pneumatischer Überdruck erzeugen. Bei verringerter Hubbewegung wird ein verbessertes Aufpumpen der Kammern erreicht. Das Volumen der Stauchkammer läßt sich verringern, wo­durch das Verhalten des Sportschuhes beim Tragen ver­bessert ist. Da der vertikale Querschnitt der Stauch­kammer zu deren Rand hin abnimmt, sind Einlaßöffnung und Auslaßöffnung im Bereich der Mitte angeordnet, damit sie auch bei stark zusammengedrückter Stauch­kammer nicht von Stauchkammerwandungen versperrt sind. Die Ladevorrichtung ist mit der Einlaßöffnung und der Auslaßöffnung etwa im "Zenit" der Balligkeit des belastenden Fußbereiches, der in der Regel die Ferse ist, angeordnet.Due to the semi-lenticular shape of the stuffer box, the dead space is minimized when the stuffer box is compressed, since the chamber roof clings to the bottom of the stuffer box. As a result, a pneumatic excess pressure corresponding to the power surge that occurs can be generated. With a reduced stroke movement, an improved inflation of the chambers is achieved. The volume of the stuffer box can be reduced, which improves the behavior of the sports shoe when worn. Since the vertical cross section of the stuffer box decreases towards the edge thereof, the inlet opening and outlet opening are arranged in the region of the center, so that they are not blocked by stuffer box walls even when the stuffer box is strongly compressed. The loading device is arranged with the inlet opening and the outlet opening approximately at the "zenith" of the crowning of the stressful foot area, which is usually the heel.

Die Stauchkammer-Mulde muß im waagerechten Quer­schnitt nicht unbedingt kreisrund sein, ist es aber in der Regel. Besonders zweckmäßig und vorteilhaft ist es, wenn die Stauchkammer-Mulde ein Verhältnis von Durchmesser zu Höhe von 5 : 1 bis 12 : 1 aufweist, was die Flachheit der Stauchkammer des er­findungsgemäßen Sportschuhes verdeutlicht. In der Praxis wird die mittige Höhe bei 5 - 7 mm und der größte Durchmesser, z.B. oben bei dem Kammerdach, bei 27 - 37 mm liegen.The stuffer box trough does not necessarily have to be circular in the horizontal cross section, but it is usually. It is particularly expedient and advantageous if the stuffer box trough has a ratio of diameter to height of 5: 1 to 12: 1, which illustrates the flatness of the stuffer box of the sports shoe according to the invention. In practice, the central height will be 5 - 7 mm and the largest diameter, for example at the top of the chamber roof, will be 27 - 37 mm.

Mit der Ladevorrichtung werden in der Regel Drücke von 0,28 - 1,4 atm (=Atmosphärenüberdruck) erzeugt, wobei beim Springen auch 2,4 - 2,8 atm erzeugt werden. Darauf wird die Ladevorrichtung abgestellt. Die Ladevorrichtung bzw. der Sportschuh wird in sei­ner Dimensionierung an die Durchschnittswerte des üb­lichen Benutzers angepaßt. Die erfindungsgemäße Lade­vorrichtung stellt auch wegen der Stauchkammer-Mulde eine verbesserte Abstützung der Ferse dar. Es findet ständig eine leichte Entladung der Sohle-Kammern statt, da diese nicht ganz dicht nach außen sind.With the loading device, pressures of 0.28-1.4 atm (= atmospheric pressure) are generally generated, with jumping also producing 2.4-2.8 atm. The loading device is placed on it. The dimensions of the loading device or sports shoe are adapted to the average values of the normal user. The loading device according to the invention also provides an improved support for the heel because of the stuffer box trough. The sole chambers are constantly unloaded slightly since they are not completely tight to the outside.

In der Regel ist das Einlaßventil dicht bei der Ein­laßöffnung angeordnet, um einen Kanal zwischen Ein­laßöffnung und Einlaßventil zu vermeiden. Besonders zweckmäßig und vorteilhaft ist es ebenso, wenn das Auslaßventil dicht bei der Auslaßöffnung angeordnet ist, da hierdurch ebenfalls Totraum vermieden ist.As a rule, the inlet valve is arranged close to the inlet opening in order to avoid a channel between the inlet opening and the inlet valve. It is also particularly expedient and advantageous if the outlet valve is arranged close to the outlet opening, since this also avoids dead space.

Besonders zweckmäßig und vorteilhaft ist es weiter­hin, wenn das Einlaßventil und/oder das Auslaßventil in vertikaler Richtung oberhalb der Einlaßöffnung bzw. unterhalb der Auslaßöffnung angeordnet ist. Die­se Anordnung ergibt sich, wenn jeglicher Totraum zwi­schen Öffnung und Ventil vermieden ist, und ist er­möglicht, weil wegen der äußerst flachen Stauchkammer in vertikaler Richtung genügend Platz für die Ventile zur Verfügung steht.It is also particularly expedient and advantageous if the inlet valve and / or the outlet valve is arranged in the vertical direction above the inlet opening or below the outlet opening. This arrangement results when any dead space between the opening and the valve is avoided, and is possible because there is enough space for the valves in the vertical direction because of the extremely flat stuffer box.

Bei der Verwirklichung des Einlaßventiles und des Auslaßventiles sollten starre Teile und feste Verbin­dungen von Ventilteilen mit sonstigen Teilen der La­devorrichtung mit der Sohle vermieden sein, da hier­durch in Verbindung mit der Elastizität des Sohlenma­terials Schäden auftreten. Die Ventilteile sollten den sonstigen Teilen der Sohle und der Ladevorrich­tung auch wegen der Materialschrumpfung angepaßt sein.When realizing the inlet valve and the outlet valve, rigid parts and firm connections of valve parts with other parts of the loading device with the sole should be avoided, since this causes damage in connection with the elasticity of the sole material. The valve parts should also be adapted to the other parts of the sole and the loading device because of the material shrinkage.

Besonders zweckmäßig und vorteilhaft ist es daher, wenn beim Auslaßventil der Ventilkörper als dünne, biegbare Kunststoff-Scheibe und/oder wenn beim Ein­laßventil eine randseitig dichtend befestigte Ventil­lamelle dichtend lose aufliegt, die mit seitlichem Abstand angeordnete Öffnungen abschließt.It is therefore particularly expedient and advantageous if the valve body in the outlet valve is in the form of a thin, bendable plastic disc and / or if in the inlet valve a valve lamella which is fastened in an edge-sealing manner lies sealingly and which closes off openings arranged at a lateral distance.

Diese Ventile sind ausnehmend flach gebaut und daher für die Anordnung über und unter dem Stauchraum be­sonders geeignet. Die Ventil-Scheibe ist luftdicht aus Kunststoff. Ein bei Zusammendrückung federnd ela­stischer Schaumstoff-Block ist ein luftdurchlässiges Federelement und dient als Druckfeder. Ein Mittenbe­reich der Ventillamelle z.B. deckt bei einer Bela­stung durch den Fuß die Einlaßöffnung ab. Die Rück­stellbewegung der Ventillamelle erfolgt aufgrund der ihr eigenen Elastizität unterstützt durch die Rück­stellelastizität der Ladevorrichtung. Die Durchbrüche sind in der Regel als feine Perforation ausgebildet.These valves are exceptionally flat and therefore particularly suitable for arrangement above and below the stowage space. The valve disc is airtight from plastic. A foam block that is resilient when compressed is an air-permeable spring element and serves as a compression spring. A central area of the valve lamella e.g. covers the inlet opening when loaded by the foot. The return movement of the valve lamella takes place due to its own elasticity supported by the resilience of the loading device. The openings are usually designed as fine perforations.

Besonders zweckmäßig und vorteilhaft ist es eben­falls, wenn von den bei voll zusammengedrückter Stauchkammer aneinander liegenden Flächen von Kammer­dach und Kammerkörper zumindest die eine mit kleinen elastisch zusammendrückbaren Noppen besetzt ist, und/oder wenn von den bei belasteter Ladevorrichtung aneinander liegenden Flächen von Ventillamelle und Kammerdach zumindest die eine mit kleinen elastisch zusammendrückbaren Noppen besetzt ist. Diese z.B. 0,2 mm dicken Noppen verhindern ein Verkleben und fördern die Trennung der einander zugeordneten Flächen und beschleunigen damit die Wirkungsweise der Ventile.It is also particularly expedient and advantageous if at least one of the surfaces of the chamber roof and chamber body lying against one another when the compression chamber is fully compressed is occupied by small elastically compressible knobs, and / or if at least the surfaces of the valve lamella and chamber roof lying against one another when the loading device is loaded one is studded with small elastically compressible knobs. These e.g. 0.2 mm thick nubs prevent sticking and promote the separation of the surfaces assigned to each other and thus accelerate the operation of the valves.

Eine besonders zweckmäßige und vorteilhafte Ausfüh­rungsform der Erfindung liegt vor, wenn die Ladevor­richtung eine Baueinheit ist, welche den Kammerkör­per, das Kammerdach, das Einlaßventil und das Aus­ laßventil umfaßt und in eine Ausnehmung der Sohle eingesetzt ist. Wegen der erfindungsgemäßen Ausbil­dung der Stauchkammer ist die Herstellung von Kammer­körper und Kammerdach aufwendiger. Dies läßt sich durch die Baueinheit in etwa ausgleichen. Die Bauein­heit vereinfacht auch die Integrierung der Ventile. Es lassen sich nun Kammerkörper und Kammerdach ge­meinsam aus einem Kunststoff fertigen, der etwas un­terschiedlich von dem Kunststoff der sonstigen Sohle ist, zumal das Kammerdach eine einer Pumpmembran ähn­liche Funktion hat und etwas dehnbar ist. Die Lade­vorrichtung bzw. deren Teile bestehen z.B. aus einem Silikon-Kautschuk.A particularly expedient and advantageous embodiment of the invention exists if the loading device is a structural unit which comprises the chamber body, the chamber roof, the inlet valve and the off Laßventil includes and is inserted into a recess in the sole. Because of the configuration of the stuffer box according to the invention, the manufacture of the chamber body and chamber roof is more complex. This can be compensated for by the unit. The assembly also simplifies valve integration. It is now possible to manufacture the chamber body and chamber roof together from a plastic which is somewhat different from the plastic of the other sole, especially since the chamber roof has a function similar to that of a pump membrane and is somewhat stretchable. The loading device or its parts consist, for example, of a silicone rubber.

Eine besonders zweckmäßige und vorteilhafte Ausfüh­rungsform der Erfindung liegt vor, wenn die Einlaß­öffnung seitlich neben der Auslaßöffnung angeordnet ist und die Ventillamelle des Einlaßventiles sowie die Ventilscheibe des Auslaßventiles an einander ent­gegengesetzten Seiten des gleichen Kammergehäuse-­Bereiches angeordnet sind. Hierdurch ist die Bauweise der Ladevorrichtung vereinfacht, ist das Einlaßventil geschützter angeordnet und ist die seitliche Zufuhr von Luft vereinfacht.A particularly expedient and advantageous embodiment of the invention is present when the inlet opening is arranged laterally next to the outlet opening and the valve lamella of the inlet valve and the valve disk of the outlet valve are arranged on opposite sides of the same chamber housing area. This simplifies the design of the charging device, the inlet valve is arranged more protected and the lateral supply of air is simplified.

Bei dem eingangs erörterten bekannten Sportschuh er­strecken sich die Kammern über nahezu die gesamte Sohle und sich im waagerechten Querschnitt eckig, wobei sie durch relativ schmale Wände voneinander ge­trennt sind. Die Festigkeit dieser Sohle gegen Knickungen und Zug in waagerechter Richtung ist rela­tiv gering. Die großen und sich weit erstreckenden Ausnehmungen bilden auch ein relativ großes Volumen, das von der Ladevorrichtung gefüllt werden und ge­füllt gehalten werden muß. Dies führt zu Schwierig­keiten, wenn man mit einem möglichst kleinem Volumen der Stauchkammer auskommen will.In the known sports shoe discussed at the beginning, the chambers extend over almost the entire sole and are angular in the horizontal cross section, being separated from one another by relatively narrow walls. The strength of this sole against buckling and tension in the horizontal direction is relatively low. The large and wide recesses also form a relatively large volume that must be filled and kept filled by the loading device. This leads to difficulties if you want to get by with the smallest possible volume of the stuffer box.

Eine weitere Aufgabe der Erfindung ist es daher, einen Sportschuh mit Sohle zu schaffen bei dem die Kammern in der Gestaltung und Verteilung verbessert sind. Ein erfindungsgemäßer Sportschuh ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Kam­mern auf die vom Fuß primär belasteten Bereiche der Sohle beschränkt sind und als vereinzelte in waage­rechter Ebene abgërundete Ausnehmungen ausgebildet sind, die durch durchgehend offene Kanäle miteinander verbunden sind.Another object of the invention is therefore to provide a sports shoe with a sole in which the chambers are improved in design and distribution. A sports shoe according to the invention solves this problem, characterized in that the chambers are limited to the areas of the sole which are primarily loaded by the foot and are designed as isolated recesses rounded off in a horizontal plane, which are connected to one another by continuously open channels.

Durch Beschränkung der Kammern auf die Bereiche von Ferse, äußerem Fußgewölberand und Mittelfuß-Ballenbe­reich ist der von Kammern besetzte Bereich der Sohle verringert, ohne daß die erwünschten Feder- und Dämp­fungseigenschaften beachtlich beeinträchtigt sind. Durch die Verringerung wird die Festigkeit der Sohle verbessert, wozu ebenso entscheidend die Abrundung der Kammern beiträgt, die z.B. ellipsenförmig sind. Es ist auch eine Verringerung des Gesamtkammervolu­mens erreicht, weshalb die erfindungsgemäße Kammerge­staltung in Verbindung mit der erfindungsgemäßen La­devorrichtungs-Gestaltung von besonderem Vorteil ist, wobei die erfindungsgemäße Ladevorrichtung bei klei­nem Stauchkammervolumen hohe Drücke ermöglicht.By restricting the chambers to the areas of the heel, outer arch edge and midfoot ball area, the area of the sole occupied by the chambers is reduced without the desired spring and damping properties being significantly impaired. The reduction improves the strength of the sole, to which the rounding of the chambers, which e.g. are elliptical. A reduction in the total chamber volume is also achieved, which is why the chamber design according to the invention in connection with the loading device design according to the invention is particularly advantageous, the charging device according to the invention allowing high pressures with a small stuffer box volume.

Der Sportschuh gemäß Fig. 1 besitzt einen Oberschuh (1), dessen Sohlenteil (2) im Fersenbereich in nicht näher gezeigter Weise luftdurchlässig ist. Der Sohlenteil ist z.B. im Fersenbereich mit gekreuzten Schlitzen versehen, um Luftdurchlässigkeit und Nach­giebigkeit zu erreichen. Im Oberschuh (1) ist ein Fuß untergebracht, dessen Ferse (3) angedeutet ist, die nach unten hin ballig ausgebildet ist. Der Oberschuh (1) ist auf einer Sohle (4) befestigt, deren Absatz (5) in Fig. 1 gezeigt ist und sich unter der Ferse (3) befindet.1 has an upper shoe (1), the sole part (2) of which is permeable to air in the heel region in a manner not shown in detail. The sole part is e.g. Crossed slits in the heel area to achieve air permeability and compliance. A foot is housed in the upper shoe (1), the heel (3) of which is indicated and which is convex downward. The upper shoe (1) is attached to a sole (4), the heel (5) of which is shown in Fig. 1 and is located under the heel (3).

Die Sohle (5) besitzt unten eine Profillage (6), da­rüber eine Kernlage (7) und darauf eine Oberlage (8), die sehr viel dünner ist als die Kernlage (7). Die Profillage (6) besteht aus einem relativ festen, we­nig zusammendrückbaren, vollen Kunststoff. Die Kern­lage (7) und die Oberlage (8) bestehen aus unterein­ander gleichem Material und zwar aus einem elastisch zusammendrückbaren, geschäumten Kunststoff. Die Sohle bzw. die Summe von Kernlage und Oberlage ist im Ab­satzbereich dicker als im übrigen Teil der Sohle. Die Oberlage (8) besitzt im Bereich des Absatzes (5) un­ter der Ferse (3) und dem luftdurchlässigen Bereich des Sohlenteiles (2) als feine Perforation ausgebil­dete Durchbrüche (9), die jeweils mit waagerechtem Abstand von einer Mitte angeordnet sind.The sole (5) has a profile layer (6) at the bottom, a core layer (7) above it and an upper layer (8) on top, which is much thinner than the core layer (7). The profile layer (6) consists of a relatively solid, little compressible, full plastic. The core layer (7) and the top layer (8) consist of the same material as one another, namely of an elastically compressible, foamed plastic. The sole or the sum of the core layer and the top layer is thicker in the sales area than in the rest of the sole. The upper layer (8) has in the area of the heel (5) under the heel (3) and the air-permeable area of the sole part (2) as perforations (9) which are each arranged at a horizontal distance from a center.

Im Bereich dieser Durchbrüche (9) ist im Absatz (5) und zwar in der Kernlage (7) eine im waagerechten Querschnitt kreisförmige Ausnehmung (10) vorgesehen, die nach unten hin geschlossen ist und zu der Oberla­ge (8) hin offen ist. Die Ausnehmung (10) geht unten mittig in eine kleine Aussparung (11) über und nimmt eine eingesetzte Baueinheit (12) auf, auf der die Oberlage (8) unverklebt lose aufliegt. Die Baueinheit (12) umfaßt einen Kammerkörper (13), ein Kammerdach (14) und eine auch mittig volle Ventillamelle (15), die jeweils aus Silikon-Kautschuk hergestellt sind, wobei die Ventillamelle auf dem Kammerdach (14) dicht und lose aufliegt und entlang dem Umfangsrand (19) mit dem Kammerdach (14) verklebt ist.In the area of these openings (9) in paragraph (5), namely in the core layer (7), a circular cross section (10) is provided, which is closed towards the bottom and is open towards the top layer (8). The recess (10) merges into a small recess (11) in the center at the bottom and receives an inserted structural unit (12) on which the top layer (8) lies loosely without being glued. The assembly (12) comprises a chamber body (13), a chamber roof (14) and a valve lamella (15), which is also full in the middle, which are each made of silicone rubber, the valve lamella resting tightly and loosely on the chamber roof (14) and being glued to the chamber roof (14) along the peripheral edge (19) .

Der Kammerkörper (13) und das Kammerdach (14) bilden ein Kammergehäuse, sind einstückig hergestellt und begrenzen eine Stauchkammer (16), die halblinsenartig ausgebildet und hier nach unten hin ausgewölbt ist. Das Kammerdach (14), das eine Art Pumpmembran dar­stellt, besitzt mittig eine Einlaßöffnung (17), und unter dieser bildet der Kammerkörper mittig eine Aus­laßöffnung (18). Das Kammerdach (14) bildet an der der Ventillamelle (15) zugewandten Seite kleine, ela­stisch zusammendrückbare Noppen (20) und auch eine der beiden einander gegenüberliegenden Flächen der Stauchkammer (16) ist mit solchen Noppen (20) verse­hen, wobei die Noppen einstückig mit dem Kammerdeckel bzw. dem Kammerkörper sind.The chamber body (13) and the chamber roof (14) form a chamber housing, are made in one piece and delimit a stuffer box (16) which is designed like a half lens and here is curved downwards. The chamber roof (14), which represents a type of pump membrane, has an inlet opening (17) in the center, and below this the chamber body forms an outlet opening (18) in the center. The chamber roof (14) forms on the side facing the valve lamella (15) small, elastically compressible knobs (20) and also one of the two opposite surfaces of the stuffer box (16) is provided with such knobs (20), the knobs being integral with the chamber cover or the chamber body.

Die Auslaßöffnung (18) geht in eine Höhlung (21) über, die in dem Kammerkörper (13) untergebracht ist und eine unter der Auslaßöffnung angeordnete Ventil-Scheibe (22) aufnimmt, die von unten von einem Feder-Block (23) aus Schaumstoff beaufschlagt ist. Die Höhlung (21) ist nach unten über einen Durchbruch (24) mit der kleinen Aussparung (11) verbunden. Wenn die Ladevorrichtung nicht arbeitet, dann ist die Ven­til-Scheibe (22) dichtend gegen die Auslaßöffnung (18) gedrückt und zwar aufgrund Belastung durch den Feder-Block (23) und durch Luftdruck, der von der kleinen Aussparung (11) her wirkt.The outlet opening (18) merges into a cavity (21), which is accommodated in the chamber body (13) and receives a valve disk (22) arranged under the outlet opening, which from below is supported by a spring block (23) made of foam is acted upon. The cavity (21) is connected at the bottom via an opening (24) to the small recess (11). When the loading device is not working, the valve disc (22) is pressed sealingly against the outlet opening (18) due to the load from the spring block (23) and air pressure acting from the small recess (11).

Bei Belastung der Ladevorrichtung wird durch Druck auf die Ventillamelle (15) die Einlaßöffnung (17) versperrt und wird die Stauchkammer (16) zusammenge­ drückt. Sobald der Druck in der Stauchkammer (16) groß genug ist, wird die Ventil-Scheibe (22) abwärts gedrückt und strömt Luft durch die Auslaßöffnung (18) zur kleinen Aussparung (11). Bei Entlastung schließt die Ventil-Scheibe (22) die Auslaßöffnung (18) und wird Luft über die Durchbrüche (9), die Durchbrüche (25) der Ventillamelle (15) und die mittige Einlaß­öffnung (17) in die Stauchkammer (16) nachgesaugt. Bei der Entlastung kommt die elastische Rückstell­kraft von Kammerkörper, Kammerdach und Ventillamelle zur Wirkung.When loading the loading device is blocked by pressure on the valve lamella (15), the inlet opening (17) and the stuffer box (16) is merged presses. As soon as the pressure in the stuffer box (16) is high enough, the valve disc (22) is pressed down and air flows through the outlet opening (18) to the small recess (11). When relieved, the valve disc (22) closes the outlet opening (18) and air is sucked into the stuffer box (16) via the openings (9), the openings (25) of the valve lamella (15) and the central inlet opening (17). The elastic restoring force of the chamber body, chamber roof and valve lamella comes into effect when the load is released.

Gemäß Fig. 2 ist die mit der kleinen Aussparung (11) versehene Ausnehmung (10) in der Kernlage (7) und zwar im Bereich des Absatzes (5) vorgesehen. Die Kernlage (7) der Sohle ist in den die Last des Schuh­benutzers primär aufnehmenden Bereichen mit Kammern (26) versehen, die hier kreisrung und im Durchmesser kleiner als die Ausnehmung (10) sind. Die nach unten geschlossenen und nach oben offenen Kammern (26) wei­sen über die Höhe gleichbleibenden Querschnitt auf. Die Kammern sind untereinander und mit der Ausnehmung (10) durch kleine, schmale Kanäle (27) verbunden und zwar in Reihe. Die Kammern (26) sind gleich groß und die Kanäle (27) erstrecken sich nur über einen Bruch­teil der Höhe der Kammern. Die Länge eines Kanales zwischen zwei benachbarten Kammern ist kleiner als der Durchmesser der Kammern.2, the recess (10) provided with the small recess (11) is provided in the core layer (7), specifically in the area of the shoulder (5). The core layer (7) of the sole is provided with chambers (26) in the areas primarily absorbing the load of the shoe user, which here are circular and smaller in diameter than the recess (10). The chambers (26) which are closed at the bottom and open at the top have a constant cross section over the height. The chambers are connected to each other and to the recess (10) by small, narrow channels (27) in a row. The chambers (26) are the same size and the channels (27) extend only over a fraction of the height of the chambers. The length of a channel between two adjacent chambers is smaller than the diameter of the chambers.

Bei der Ausführungsform gemäß Fig. 3 und 4 ist die Ladevorrichtung ebenfalls als Baueinheit (12) ausge­bildet. In Abweichung von der Ausführungsform gemäß Fig. 1 ist das Kammerdach (14) durchgehend voll, das heißt ohne Durchbruch und befinden sich seitlich ne­ben der mittigen Auslaßöffnung (18) noch im Mittenbe­reich der Mulde dicht bei der Auslaßöffnung (2) Ein­laßöffnungen (17). Jede Einlaßöffnung befindet sich am inneren Ende eines Kanales (28), der im Kammerkör­per (13) radial nach außen führt. Die Ventillamelle (15) bildet den gewölbten Boden der Stauchkammer (16) und ist von der Mitte her radial nach außen bis zu einem gestrichelten Kreis (29) lose vom übrigen Kam­merkörper. Sie besitzt oberhalb der Auslaßöffnung (18) einen Durchbruch (30) und besitzt eine radial nach außen zunehmende Dicke. Zwischen dem Durchbruch (30) und den Einlaßöffnungen (17) befindet sich je­weils ein Bereich, in dem die Ventillamelle (15) dichtend auf dem Ventilkörper (13) aufliegt.In the embodiment according to FIGS. 3 and 4, the loading device is also designed as a structural unit (12). In a departure from the embodiment according to FIG. 1, the chamber roof (14) is completely full, that is to say without a breakthrough, and is located laterally next to the central outlet opening (18) and in the middle region of the trough close to the outlet opening (2). Every inlet opening is located at the inner end of a channel (28) leading radially outwards in the chamber body (13). The valve lamella (15) forms the curved bottom of the stuffer box (16) and is loose from the center radially outwards to a dashed circle (29) from the rest of the chamber body. It has an opening (30) above the outlet opening (18) and has a radially increasing thickness. Between the opening (30) and the inlet openings (17) there is in each case an area in which the valve lamella (15) lies sealingly on the valve body (13).

Wenn die Ladevorrichtung sich entspannt und die Stauchkammer (16) Luft ansaugt, so hebt die Ventilla­melle (15) ab, so daß Luft durch den Kanal (28) und den Durchbruch (30) in die Stauchammer (16) strömen kann. Die Ventillamelle (15) ist dort, wo sie Dicht­funktion hat, sehr dünn, und dort, wo sie den Kanal (28) abdeckt, dicker und damit fester.When the loading device relaxes and the stuffer box (16) sucks in air, the valve lamella (15) lifts off, so that air can flow through the channel (28) and the opening (30) into the stuffer box (16). The valve lamella (15) is very thin where it has a sealing function and where it covers the channel (28) it is thicker and therefore firmer.

Wenn Pumpdruck in der Stauchkammer (16) herrscht, wird die Ventillamelle im Dichtbereich gegen den Kam­merkörper gedrückt, wodurch die Verbindung zwischen Stauchkammer und Kanal (28) gesperrt wird. Die Höh­lung (21) ist nach unten durch eine perforierte Mem­bran (31) abgesperrt und die Ventil-Scheibe arbeitet ohne besondere Druckfeder.If there is pump pressure in the stuffer box (16), the valve lamella in the sealing area is pressed against the chamber body, as a result of which the connection between the stuffer box and the channel (28) is blocked. The cavity (21) is shut off at the bottom by a perforated membrane (31) and the valve disc works without a special compression spring.
