Description

  • Die vorliegende Erfindung bezieht sich auf einen Sportschuh, insbesondere für Laufdisziplinen über größere Distanzen, gemäß dem Oberbegriff des Anspruches 1. The present invention relates to a sports shoe, in particular for running disciplines over longer distances, according to the preamble of claim 1.
  • Ein derartiger Laufschuh ist aus der US-PS 4 364188 bekannt. Such a running shoe is known from US-PS 4 364,188th Dort ist zur guten Dämpfung der beim Laufen insbesondere im Ballenbereich und im Fersenbereich auftretenden hohen Druck- und Schockbelastungen in diesen beiden Bereichen je ein inselförmiges Polster in der weichen Zwischensohle vorgesehen, das noch weicher ist als der übrige Teil der Zwischensohle. There, occurring when running especially in the ball area and the heel area high pressure and shock loads in these two areas is provided in each one island-shaped upholstered in soft midsole for good cushioning, which is softer than the rest of the midsole. Zur Steuerung der Dämpfung und zur Stabilisierung der Laufeigenschaften im Fersenbereich sind dort angrenzend an das inseiförmige Polster zur Innenseite des Laufschuhes hin mehrere zylindrische Stöpsel aus härterem elastischem Material als der Zwischensohle in diese Zwischensohle eingesetzt. For controlling the damping and stabilizing the running properties in the heel area there are inserted adjacent to the inseiförmige pad to the inside of the running shoe towards a plurality of cylindrical plug made of a harder elastic material than the intermediate sole in this midsole. Um den Schuh an die spezifischen Bedürfnisse des jeweiligen Läufers anpassen zu können, sind Stöpsel unterschiedlicher Härte in die Bohrungen der Zwischensohle von der Laufsohle her einsteckbar. In order to adapt the shoe to the specific needs of each rotor, plugs of different hardness in the holes of the midsole of the outsole ago can be inserted. Meherere solcher Stöpsel können an einen Träger angeformt sein und gemeinsam in die Zwischensohle eingesetzt werden, wobei der Träger nach dem Einsetzen einen Teil der Laufsohle mitbildet. Meherere such plugs can be formed on a support and are used together in the midsole, wherein the carrier after insertion of co-forms a part of the outsole.
  • Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, einen Sportschuh der eingangs erwähnten Art bezüglich der Fixierung der Dämpfungsglieder und der Erweiterung des Dämpfungs-Einstellbereiches zu verbessern. With the present invention, the problem to be solved relative to improve a sports shoe of the type mentioned in the fixing of the damping members and the expansion of the attenuation setting range.
  • Gelöst wird diese Aufgabe durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale. This object is achieved by the features specified in the characterizing part of claim 1. Durch das angewendete Zylinder-Kolben-Prinzip erhält man eine bessere Fixierung der Dämpfungselemente gegen seitliche Ausweichung in der weichen Zwischensohle und außerdem können mehrere Dämpfungsscheiben unterschiedlicher « Härte bzw. Kompressibilität übereinander angebracht und damit eine fast beliebige Dämpfungs- bzw. Federcharakteristik erreicht werden. By the applied cylinder-piston principle, a better fixation of the damping elements against lateral evasion in the soft midsole and also a plurality of damping discs can different "hardness or compressibility one above the other and thus an almost arbitrary damping and spring characteristics are achieved.
  • Weitere vorteilhafte Einzelheiten der Erfindung sind in den Unteransprüchen angegeben und werden nachfolgend anhand der in der Zeichnung veranschaulichten Ausführungsbeispiele näher beschrieben. Further advantageous details of the invention are specified in the subclaims and will be described in more detail below with reference to the illustrated embodiments in the drawing. Dabei zeigen : They show:
    • Figur 1 einen Abschnitt einer mehrschichtigen Sohle eines erfindungsgemäßen Sportschuhes und 1 shows a portion of a multi-layered sole of an athletic shoe according to the invention and
    • Figur 2 die Unteransicht auf die Zwischensohle eines derartigen Sportschuhes. 2 shows the bottom view of the midsole of such a sports shoe.
  • Mit 1 ist eine Sohle eines Sportschuhes, insbesondere für Laufdisziplinen, vorzugsweise für Langstrecken, bezeichnet. 1 is a sole of a sport shoe, in particular for running disciplines, preferably for long-distance referred to. Diese besteht aus der eigentlichen Laufsohle 2 aus abriebfestem Material, einer Zwischensohle 3 aus weichelastischem, insbesondere hochporösem Material, wie geschäumtem Polyurethan, mit einem spezifischen Gewicht von 0.02 bis 0,04 g/cm 3 , und einer oberen Brandsohle 4 oder einer entsprechend ausgebildeten Innensohle aus wieder härterem, elastischem Material, wie beispielsweise Leder, Preß-oder Faserstoff oder auch aus Kunststoffen. This consists of the actual sole 2 made of abrasion resistant material, a midsole 3 made of flexible, especially highly porous material such as foamed polyurethane having a specific gravity of 0.02 to 0.04 g / cm 3, and an upper-insole 4, or a correspondingly formed inner sole from a harder again, elastic material, such as leather, pressing or fibrous material or of plastics. Die einzelnen Sohlenteile sind beispielsweise durch Ausschäumen oder durch Kleben miteinander verbunden. The individual parts of the sole are connected together, for example, by foaming or by gluing. Die Laufsohle 2 kann auf der Lauffläche mit an sich bekannten, je nach Verwendungszweck unterschiedlichen Profilen versehen sein. The outsole 2 may be provided on the tread surface are known per se, depending on the intended use different profiles.
  • Erfindungsgemäß sind zur Einstellung der Dämpfungseigenschaft bzw. der Federcharakteristik der gesamten Sohle in der Zwischensohle 3 senkrecht stehende Zylinder vorgesehen. According to the invention the damping characteristic and spring characteristic of the entire sole in the midsole 3 perpendicular cylinders are provided for adjustment. In diese sind vorzugsweise von der Laufsohle 2 aus Dämpfungsscheiben 6 aus gleichem Material oder aus Material mit unterschiedlichen Dämpfungseigenschaften einsetzbar. In these are preferably of the outsole 2 of damping discs 6 of the same material or of material having different damping characteristics can be used. Die Zylinder 5 sind von unten durch ein Verschlußteil 7 fest verschließbar. The cylinders 5 are fixedly closable from below by a closure member. 7 In die Zylinder 5 taucht je ein Kolben 8 ein, der zumindest beim Laufen, also bei Belastung, gegen die Dämpfungsscheiben 6 drückt. In the cylinder 5, a piston 8, depending immersed, at least suppressed while running, thus under load against the damping discs. 6
  • Beim dargestellten Ausführungsbeispiel sind die Kolben 8 alle an der Brandsohle 4 bzw. Innensohle angebracht bzw. sie bilden mit dieser ein einheitliches Bauteil, beispielsweise ein Kunststoffspritzteil. In the illustrated embodiment, the pistons 8 are mounted all of the insole or inner sole 4, or they form with this a single component, for example a plastic injection-molded part. Zugleich stützen sich die Zylinder 5 von innen an der Laufsohle 2 ab, oder sie sind an dieser befestigt, beispielsweise durch Kleben und/oder Verrastungen und/oder durch Vernieten oder dergleichen, oder aber sie bilden vorzugsweise mit dieser eine bauliche Einheit. At the same time the support cylinder 5 to the inside of the outsole 2 from, or are fixed thereto, for example by gluing and / or latching devices and / or by riveting or the like, or they preferably form with this a structural unit. Die Zylinder 5 können auch an der Brandsohle 4 angebracht sein, während die Kolben 8 dann an der Laufsohle 2 sitzen oder durch die Zwischensohle 3 gehaltert sind. The cylinder 5 may also be attached to the insole 4, while the piston 8 then sit on the outsole 2 or are supported by the midsole. 3 In diesem Falle kann das Verschlußteil 7 zugleich als Kolben ausgebildet sein, wie in Figur 1 in den beiden rechten Ausführungsbeispielen vorgesehen, bei dem das Verschlußteil 7 in die Laufsohle 2 einschraubbar oder einrastbar und/oder einklebbar ist und noch in den Zylinder 5 eintaucht. In this case, the shutter member 7 may be also formed as a piston, as provided in Figure 1 in the two right-hand embodiments, in which the closing part 7 is screwed into the outsole 2 or snapped and / or be glued and immersed still in the cylinder. 5 Zwischen Brandsohle 4 und Zwischensohle 3 oder im Anschluß an die Brandsohle 4 zum Schuhinneren hin kann noch eine Innensohle aus hartem, elastischem Material vorgesehen sein und diese kann dann die Kolben 8 oder die Zylinder 5 tragen oder mit diesem eine bauliche Einheit bilden. Between the insole 4 and the midsole 3, or subsequent to the insole 4 to the shoe towards the inside of yet an insole made of hard, elastic material may be provided and this can then the pistons 8, or the cylinder 5 carry or form with the latter a structural unit. Auch ist es grundsätzlich möglich, die Zwischensohle 3 aus mehreren Schichten mit gleichem oder unterschiedlichem Schäumungsgrad und damit Dämpfungscharakteristik auszubilden. Also, it is in principle possible to form the midsole 3 from a plurality of layers with the same or different degree of foaming and thus damping characteristics.
  • Das äußere linke Ausführungsbeispiel der Figur 1 zeigt ein topf- oder haubenförmiges Verschlußteil 7, das in den an der Laufsohle 2 mittels eines Flansches 9 anliegenden oder befestigten Zylinder 5 einschraubbar ist. The outer left embodiment of Figure 1 shows a cup-shaped or dome-shaped closure member 7, which is screwed into the adjacent or on the sole 2 by means of a flange 9 of fixed barrels. 5 Der Topfboden 10 ist mit einem Dreh-Angriffselement 11, beispielsweise einer Leiste oder einem Schlitz- oder Innenvielkant der dergleichen versehen. The cup bottom 10 is 11, for example a bar or a slot or the like of the internal polygon provided with a rotary engaging member. Durch die Einschraubmöglichkeit des Verschlußteiles 7 . By Einschraubmöglichkeit the closure part. 7 kann zusätzlich je nach Einschraubtiefe eine Feineinstellung der Dämpfungs- oder Federcharakteristik vorgenommen werden. can be carried out in addition, depending on the screw, a fine adjustment of the damping or spring characteristic. Vorzugsweise kann die verbleibende Laufsohlenöffnung 12 mit einem beispielsweise einspreizbaren oder einpreßbaren Blinddeckel 13, insbesondere aus Aluminiumblech, Kunststoff oder dergleichen verschlossen sein. Preferably, the remainder of the outsole opening 12 can be closed by an example einspreizbaren or einpreßbaren blind cover 13, in particular from sheet aluminum, plastic or the like.
  • Günstigerweise können die Zylinder 5, zumindest auf der Kolbeneintauchseite am freien Rand 14 nach außen, beispielsweise trichterförmig erweitert sein. Conveniently, the cylinder 5 can, at least on the piston side of immersion at the free edge 14 to the outside, for example, be flared.
  • Die Anordnung der Zylinder 5 mit den Dämpfungsscheiben 6 und den Kolben 8 kann über die gesamte Sohle 1 verteilt sein. The arrangement of the cylinders 5 with the damper discs 6 and the piston 8 may be distributed over the entire sole. 1 Vorzugsweise sind sie jedoch, wie in Figur 2 dargestellt, um die beim Laufen besonders beanspruchten Bereiche, nämlich im Ballenbereich 15 und insbesondere im Fersenbereich 16 vorgesehen. Preferably, they are as shown in Figure 2, however, provided to the particularly stressed when running areas, namely in the ball region 15 and in particular in the heel area sixteenth Bei letzteren sind sie vorzugsweise zu beiden Seiten und im Ballenbereich 15 zu beiden Seiten und dahinter angeordnet. In the latter case they are preferably arranged on both sides and in the ball region 15 on both sides and behind. Hierdurch werden die Schockbeanspruchungen in diesen Bereichen vermindert, indem sie auf einen größeren Druckbereich mit gezielt einstellbarer Dämpfungscharakteristik verteilt werden. Thereby, the shock stresses are reduced in these areas in that they are distributed over a larger pressure range with selectively adjustable damping characteristic.
  • Die Zylinder 5 und die Kolben 8 sind derart ausgebildet, daß die Zylinder 5 mindestens 40 % bis maximal 80 % in die Mittelsohle 3 eingreifen, wobei die Kolben 8 mindestens 5 % bis maximal 90 % in die Zylinder 5 eintauchen können. The cylinders 5 and the pistons 8 are formed such that the cylinders engage at least 40 5% and 80% in the midsole 3, wherein said piston 8 can immerse at least 5% up to 90% into the cylinders. 5 Hierdurch wird gewährleistet, daß die Kolben 8 ausreichend in die Zylinder 5 eingreifen und in diesen geführt sind. This ensures that the piston 8 sufficiently engage into the cylinder 5 and is guided in this. Andererseits sind auch die Zylinder 5 in ausreichendem Maße in der Mittelsohle 3 gegen seitliche Auslenkung gehaltert, selbst wenn sie nicht an der Laufsohle 2 bzw. an der Brandsohle 4 oder einer zwischen der Brandsohle 4 und der Mittelsohle 3 vorhandenen Innensohle befestigt sind. On the other hand, the cylinders are supported 5 sufficiently in the midsole 3 against lateral displacement, even if they are not fixed to the outsole 2 or on the insole 4 or an existing between the insole 4 and the midsole 3 insole.
  • Wie bereits angedeutet, können in den einzelnen Zylindern 5 eine odermehrere Dämpfungsscheiben 6 untergebracht werden. As already indicated, one or more damper discs 6 can be accommodated in the individual cylinders. 5 Im Falle der Verwendung mehrerer Dämpfungsscheiben 6 je Zylinder-Kolbenpaar 5,8 können auch Dämpfungsscheiben 6 mit unterschiedlicher Dämpfungs- oder Federcharakteristik verwendet werden, um je nach Art der Belastung die optimale Dämpfung einstellen zu können. In the case of using a plurality of damping discs 6 for each cylinder-piston pair 5,8 may be used with different damping or spring characteristic and damping disks 6, depending on the type of load in order to set optimal damping. Die Dämpfungsscheiben 6 bestehen vorzugsweise aus elastisch nachgiebigem, volumenkompressiblem Material, wie geschäumten Kunststoffen mit höherem oder niedrigerem Schäumungsgrad. The damping plates 6 are preferably made of an elastically resilient, volumenkompressiblem material, such as foamed plastics with a higher or lower degree of foaming.
  • Insbesondere im Falle der Anordnung der Kolben 8 an der Laufsohle 2 und der Lagerung der Zylinder 5 in der Zwischensohle 3 ist auch eine Beschickung der Zylinder-Kolbenpaare 5,8 mit den Dämpfungsscheiben 6 brandsohlenseitig möglich, falls die Brandsohle 4 und/oder Innensohle als herausnehmbare Sohlenschicht, beispielsweise durch eine Klettenverschlußverbindung ausgebildet ist. Particularly in the case of the arrangement of the pistons 8 on the sole 2 and the mounting of the cylinder 5 in the midsole 3 is also a feed to the cylinder-piston pairs 5.8 insole side possible with the damping discs 6, if the insole 4, and / or insole as removable , for example, is formed by a velcro connection sole layer.
  • Grundsätzlich kann die Anordnung der Zylinder-Kolbenpaare 5,8 auch so getroffen werden, daß sie die « weichen Ballen- und Fersenbereiche 15, 16 vollkommen koaxial in einer oder mehreren Reihen umgeben. In principle, the arrangement, the cylinder-piston pairs 5,8 also be such that it totally 16 coaxially surround the "soft ball and heel areas 15, in one or more rows. Auch ist es möglich, laufsohlenaußenseitig eine Dämpfung mit weicherer Dämpfungscharakteristik als laufsohleninnenseitig vorzusehen. It is also possible, sole on the outside to provide a damping with a softer damping characteristic as outsole inside.
