Description

SOHLENKONSTRUKTION FÜR EINEN FLEXIBLEN SCHUH  SOLE STRUCTURE FOR A FLEXIBLE SHOE
GEBIET DER ERFINDUNG FIELD OF THE INVENTION
Die vorliegende Erfindung betrifft eine Sohlenkonstruktion für einen flexiblen Schuh mit einer zumindest teilweise beim Laufen mit dem Boden in Kontakt kommenden, weichelastischen Mittelsohle, welche quer zu ihrer Längsrichtung ausgerichtete, nach unten gegen den Boden vorstehende, seitlich offene, rinnenförmige Elemente mit flachem Boden aufweist. Weiter weist die Mittelsohle eine die rinnenförmigen Elemente jeweils überbrückende Randleiste auf, welche den Querschnitt der Rinnen in den rinnenförmigen Elementen verengt, und die Höhe der seitlichen Öffnungen der rinnenförmigen Elemente bestimmt. Die nach aussen gerichteten Stirnseiten der rinnenförmigen Elemente sind mit horizontalen Sollfaltkerben versehen. Unter der Wirkung von vertikal und/oder in Längsrichtung wirkenden, beim Laufen auftretenden Kräften sind die rinnenförmigen Elemente bis zum Verschluss ihrer seitlichen Öffnungen im Bereich der Randleiste vertikal und/oder in Längsrichtung verformbar. The present invention relates to a sole construction for a flexible shoe having a soft-elastic midsole in contact at least in part with running, which has transversely to its longitudinal direction, downwardly projecting towards the bottom, laterally open, channel-shaped elements with flat bottom. Next, the midsole on the channel-shaped elements each bridging skirt, which narrows the cross section of the grooves in the channel-shaped elements, and determines the height of the lateral openings of the channel-shaped elements. The outwardly directed end faces of the channel-shaped elements are provided with horizontal Sollfaltkerben. Under the effect of vertically and / or longitudinally acting forces, the trough-shaped elements are deformable vertically and / or in the longitudinal direction until their side openings are closed in the region of the edge strip.
STAND DER TECHNIK STATE OF THE ART
Eine solche Sohlenkonstruktion ist aus DE20201400301 6 U 1 bekannt. Beim Verschluss der seitlichen Öffnungen der rinnenförmigen Elemente unter den beim Auftreten wirken- den Kräften kommt es der bekannten Sohlenkonstruktion zu einer Berührung der Rinnenböden mit der Randleisten-Unterseite. Dadurch wird die Verformung der rinnenförmigen Elemente im wesentlichen gestoppt und eine feste Standfläche für das Abstossen beim nachfolgenden Schritt erzeugt. Durch Reibung wird zudem die horizontale Verschiebbarkeit, d.h. die Verschiebbarkeit in Längsrichtung der sich berührenden Flächen gegeneinander behindert, was dem erwähnten Schwimmeffekt entgegenwirkt. Such a sole construction is known from DE20201400301 6 U 1. When closing the lateral openings of the channel-shaped elements under the forces acting on the occurrence of the known sole construction comes to a touch of the channel bottoms with the edge strip bottom. As a result, the deformation of the channel-shaped elements is substantially stopped and creates a solid footprint for the repulsion in the subsequent step. Friction also causes the horizontal displaceability, i. the displacement in the longitudinal direction of the touching surfaces obstructed against each other, which counteracts the aforementioned swimming effect.
Günstig für diese gewünschten Effekte ist es, wenn sich die rinnenförmigen Elemente durch Scheren flach ablegen und dabei die flachen Rinnenböden flächig an der Randleisten-Unterseite zur Anlage kommen. Dieses Deformationsverhalten soll unterstützt wer- den durch die Sollfallkerben, welche sich bei der bekannten Sohlenkonstruktion durch mehrere übereinander angeordete, horizontale Rillen ergeben, die sowohl auf Höhe der seitlichen Öffnungen der rinnenförmigen Elemente als auch im Bereich der Randleiste gleichmässig verteilt angeordnet sind. It is favorable for these desired effects if the channel-shaped elements lay flat by shearing and thereby the flat channel bottoms come to rest flat against the edge of the edge strip. This deformation behavior should be supported the by the desired fall notches, which result in the known sole construction by several übereinordete each other, horizontal grooves, which are arranged evenly distributed both at the level of the lateral openings of the channel-shaped elements and in the region of the edge strip.
ALLGEMEINE BESCHREIBUNG DER ERFINDUNG GENERAL DESCRIPTION OF THE INVENTION
Die Erfindung stellt sich die Aufgabe, eine Sohlenkonstruktion der eingangs genannten Art funktionell weiter zu verbessern. The invention has as its object to functionally improve a sole construction of the type mentioned.
Diese Aufgabe wird erfindungsgemäss gelöst durch eine Sohlenkonstruktion gemäss An- spruch 1 . Die erfindungsgemässe Sohlenkonstruktion ist demnach dadurch gekennzeichnet, dass die Sollfaltkerben eine der Höhe der seitlichen Öffnungen der rinnenförmigen Elemente entsprechende vertikale Breite aufweisen und mit den seitlichen Öffnungen der rinnenförmigen Elemente jeweils fluchten. This object is achieved according to the invention by a sole construction according to claim 1. The sole construction according to the invention is accordingly characterized in that the desired folding notches have a vertical width corresponding to the height of the lateral openings of the channel-shaped elements and are in each case aligned with the lateral openings of the channel-shaped elements.
Auf Grund ihrer Ausbildung mit grosser Breite und ihrer Anordnung in Flucht mit den seitlichen Öffnungen der rinnenförmigen Elemente ist die Wirkung der Sollfaltkerben nach der Erfindung erheblich ausgeprägter, lokal konzentriert sowie die Deformation dadurch stärker führend als dies mit der Vielzahl von über einen grösseren Bereich Rillen bei der an bekannten Sohlenkonstruktion möglich ist. Due to their design with a large width and their arrangement in alignment with the lateral openings of the channel-shaped elements, the effect of Sollfaltkerben invention is considerably more pronounced, locally concentrated and the deformation thereby more leading than this with the large number of grooves over a larger area which is possible on known sole construction.
Die Rillen der bekannten Sohlenkonstruktion erleichtern zwar ebenfalls die Deformation der rinnenförmigen Elemente, doch unterstützen sie eher eine über deren Höhe gleichmässig verteilte Deformation ähnlich wie beim Faltenbalg einer Ziehharmonika. Unter schiefer Belastung wird vornehmlich nur eine Flanke der rinnenförmigen Elemente komprimiert wodurch es zu einer Verformung ihrer flachen Böden mit Wulstbildung kommt. Bei der erfindungsgemässen Ausbildung neigen die rinnenförmigen Elemente bereits bei nur leicht schiefer Belastung zum Scheren unter weitgehender Beibehaltung ihrer flachen Bodenform ohne Wulstbildung. Although the grooves of the known sole construction also facilitate the deformation of the channel-shaped elements, but rather support a uniform over the height uniformly distributed deformation similar to the bellows of a concertina. Under oblique load, only one flank of the channel-shaped elements is primarily compressed, resulting in a deformation of their flat bottoms with bead formation. In the inventive design, the channel-shaped elements tend even with only slightly slated stress for shearing while largely maintaining their flat bottom shape without bead formation.
Die Sollfaltkerben können eine Tiefe aufweisen, die 2,0 - 8,0 mm, vorzugsweise ein Drittel ihrer vertikalen Breite entspricht. Weitere bevorzugte Ausbildungen der erfindungsgemässen Sohlenkonstruktion sind in den abhängigen Ansprüchen 2 - 5 angegeben, wobei diese Ausbildungen allerdings auch schon bei der bekannten Sohlenkonstruktion bevorzugt vorhanden sind. The Sollfaltkerben may have a depth which corresponds to 2.0 - 8.0 mm, preferably one third of its vertical width. Further preferred embodiments of the sole construction according to the invention are specified in the dependent claims 2-5, but these embodiments are preferably already present in the known sole construction.
Die Mittelsohle kann rationell einstückig durch Spritzgiessen hergestellt werden. The midsole can be rationally manufactured in one piece by injection molding.
KURZE BESCH REI BUNG DER ZEICH NU NGEN BRIEF DESCRIPTION OF THE NUMBER
Nachstehend wird ein Ausführungsbeispiel der Erfindung mit Bezug auf die Zeichnungen beschrieben . Es zeigen: Hereinafter, an embodiment of the invention will be described with reference to the drawings. Show it:
Fig. 1 einen rechten Schuh mit einer erfindungsgemässen Sohlenkonstruktion von seiner lateralen Seite perspektivisch schräg von hinten; und Figure 1 shows a right shoe with a novel sole construction from its lateral side in perspective obliquely from behind. and
Fig. 2 den Schuh von Fig. 1 von unten. Fig. 2 shows the shoe of Fig. 1 from below.
WEG ZUR AUSFÜ HRUNG DER ERFINDUNG WAY FOR IMPLEMENTING THE INVENTION
Bei dem in Fig. 1 dargestellten Schuh bezeichnet 1 0 das den Fuss umschliessende Ober- teil und 20 eine weichelastische Mittelsohle einer erfindungsgemässen Sohlenkonstruktion. Unter weitgehendem Verzicht auf eine Aussensohle ist die Mittelsohle 20 zum Teil direkt mit dem Boden in Kontakt. In Fig. 1 ist von der Sohlenkonstruktion nur die M ittelsohle 20 sichtbar. In the shoe illustrated in FIG. 1, 1 0 denotes the upper part enclosing the foot, and 20 a soft-elastic midsole of a sole construction according to the invention. Substantially dispensing with an outsole, the midsole 20 is in part directly in contact with the ground. In Fig. 1 of the sole construction, only the m ittelsohle 20 is visible.
Die Mittelsohle 20 weist in Längsrichtung des Schuhs mehrere, sich quer zur Längsrich- tung erstreckende, etwa gleich breite sowie etwa gleichmässig verteilt angeordnete rin- nenförmige Elemente auf. Lediglich eines dieser Elemente ist in Fig. 1 mit 2 1 bezeichnet. The midsole 20 has, in the longitudinal direction of the shoe, a plurality of annular elements which extend transversely to the longitudinal direction and have approximately the same width and are distributed approximately uniformly. Only one of these elements is designated in Fig. 1 with 2 1.
Durch eine Randleiste 23 ergibt sich aussenseitig eine Verstärkung der rinnenförmigen Elemente 2 1 . Die Randleiste 23 umrahmt eine in Fig . 1 nicht sichtbare, inkompressible aber elastisch biegsame Platte, die etwa auf Höhe des oberen Randes der Randleiste 23 bündig mit diesem oberen Rand zwischen dem Oberteil 1 0 und der Mittelsohle 20 eingebettet und mit diesen Teilen verbunden ist. Die Platte weist nur eine Dicke von ca. 2 mm auf, so dass die lichte Höhe der Rinnen in den rinnenförmigen Elementen 2 1 innerhalb der durch die Randleiste 23 bewirkten Umrahmung etwa doppelt so gross ist wie die Hö- he der seitlichen Öffnungen 24 unterhalb er Randleiste 23. Anders ausgedrückt überbrückt die Randleiste 23 ) die rinnenförmigen Elemente 2 1 aussenseitig unter Verengung von deren Querschnitt. By a skirt 23 results on the outside a gain of the channel-shaped elements 2 first The skirt 23 frames a in Fig. 1 invisible, incompressible but elastically flexible plate which is embedded approximately at the height of the upper edge of the skirt 23 flush with this upper edge between the upper part 1 0 and the midsole 20 and connected to these parts. The plate has only a thickness of about 2 mm, so that the clear height of the grooves in the channel-shaped elements 2 1 within the framing caused by the skirt 23 framing is about twice as large as the height In other words, the edge strip 23) bridges the channel-shaped elements 2 1 on the outside under the narrowing of their cross-section.
Durch die von der Randleiste 23 umrahmte Platte wird die Mittelsohle 20 ausgesteift, wobei die Platte im wesentlichen die integrale, elastische Flexibilität der Sohlenkonstruktion bestimmt. Die eher lokale, elastische Flexibilität wird durch die rinnenförmigen Elemente 21 der Mittelsohle 20 bestimmt. The midsole 20 is stiffened by the plate surrounded by the skirt 23, wherein the plate essentially determines the integral, elastic flexibility of the sole construction. The more local, elastic flexibility is determined by the channel-shaped elements 21 of the midsole 20.
An ihren nach aussen gerichteten Stirnseiten sind die rinnenförmigen Elemente 2 1 an ihrer vorderen und hinteren Flanke jeweils mit einer horizontalen Sollfaltkerbe 25 verse- hen. Die Sollfaltkerben 25 weisen eine der Höhe der seitlichen Öffnungen 24 etwa entsprechende vertikale Breite auf und fluchten sowohl miteinander als auch mit den seitlichen Öffnungen 24 jeweils auf gleicher Höhe. At their outwardly directed end faces, the channel-shaped elements 2 1 are each provided with a horizontal desired fold groove 25 on their front and rear flanks. The Sollfaltkerben 25 have a height of the lateral openings 24 approximately corresponding vertical width and are aligned both with each other and with the lateral openings 24 at the same height.
An den hintersten Elementen 2 1 ist eine den Sollfaltkerben25 entsprechende Einbuchtung 26 vorhanden, die sich zum Teil noch um den Fersenteil herum erstreckt. Die Sollfaltkerben 25 weisen eine Tiefe auf, die 2,0 - 8,0 mm, vorzugsweise jedoch ein Drittel ihrer vertikalen Breite entspricht. In Fig. 1 sind die Sollfaltkerben abgerundet dargestellt, doch könnten sie auch v-förmig ausgebildet sein. At the rearmost elements 2 1 is a Sollfaltkerker25 corresponding recess 26 is present, which extends in part still around the heel part. The Sollfaltkerben 25 have a depth which corresponds to 2.0 - 8.0 mm, but preferably one third of its vertical width. In Fig. 1, the Sollfaltkerben are shown rounded, but they could also be V-shaped.
Vom Fersenbereich zum Ballenbereich hin nimmt die Dicke der rinnenförmigen Elemente tendenziell ab. In Längsrichtung des Schuhs nimmt bei gleicher äusserer Breite auch die Wandstärke der rinnenförmigen Elemente 21 vom Fersenbereich zum Ballenbereich hin ab. Im Fersenbereich sind die rinnenförmigen Elemente 21 vorderseitig zudem etwas dicker als rückseitig, im Mittelfussbereich vorder- und rückseitig etwa gleich dick und im Ballenbereich vorderseitig etwas dünner als rückseitig. From the heel area to the ball area, the thickness of the channel-shaped elements tends to decrease. In the longitudinal direction of the shoe, with the same outer width, the wall thickness of the channel-shaped elements 21 also decreases from the heel area to the ball area. In the heel area, the channel-shaped elements 21 are also slightly thicker on the front side than on the back, slightly thicker on the front and rear sides of the midfoot area and somewhat thinner on the front side in the ball area.
Die Böden 27 der rinnenförmigen Elemente 21 sind jeweils flach ausgebildet und zwar sowohl auf ihrer Oberseite in den Rinnen als auch auf ihrer Unterseite. Zusammen mit der Randleiste 23 und etwas geneigten Flanken der Rinnen ergeben sich dadurch etwa trapezförmige Querschnitte für die seitlichen Öffnungen 24. The bottoms 27 of the channel-shaped elements 21 are each formed flat both on its upper side in the grooves and on its underside. Together with the edge strip 23 and slightly inclined flanks of the grooves, this results in approximately trapezoidal cross-sections for the lateral openings 24th
Der gegenseitige Abstand der rinnenförmigen Elemente 21 ist in Längsrichtung des Schuhs so gross gewählt, dass sie individuell durch Scherung in dieser Richtung bis zum Verschluss ihrer seitlichen Öffnungen 24 durch flaches Ablegen verformbar sind. Diese Art der Verformung wird durch die Sollfaltkerben 25 wesentlich begünstigt bzw. unterstützt. The mutual distance of the channel-shaped elements 21 is chosen so large in the longitudinal direction of the shoe that they individually by shearing in this direction until Closure of their lateral openings 24 are deformed by laying flat. This type of deformation is much favored or supported by the Sollfaltkerker 25.
Wie dies in Fig. 2 mit Blick von unten auf die Lauffläche des Schuhs erkennbar ist, erstreckt sich ein Längsschlitz 22 in der Mittelsohle 20 vom Fersenbereich bis in den Ballenbereich annähernd über die gesamte Länge des Schuhs, wodurch die Mittelsohle 20 in einen medialen und einen lateralen Teil unterteilt ist. Die beiden Teile sind lediglich hinten am Schuhende und vorn an der Schuhspitze miteinander verbunden. Durch den Längsschlitz 22 ergeben sich lateralseitig und medialseitig nebeneinander angeordnete Paare von rinnenförmigen Elementen 21 , die unabhängig voneinander verformbar sind. As can be seen in Fig. 2 seen from below on the tread of the shoe, a longitudinal slot 22 extends in the midsole 20 from the heel area to the ball area approximately over the entire length of the shoe, whereby the midsole 20 in a medial and a lateral part is divided. The two parts are connected only at the back of the shoe end and front of the toe. The longitudinal slot 22 results in lateral and medial side by side pairs of channel-shaped elements 21, which are deformable independently of each other.
Gemäss Fig. 2 ist der Längsschlitz 22 in sich gebogen und so angeordnet, dass die rinnenförmigen Elemente 21 im Fersenbereich und Mittelfussbereich medial kürzer als lateral und im Ballenbereich medial länger als lateral sind. Durch die Form und Lage des Längsschlitzes lässt sich insbesondere die Abrollcharakteristik der Sohlenkonstruktion beeinflussen und einstellen. According to FIG. 2, the longitudinal slit 22 is bent in itself and arranged such that the channel-shaped elements 21 are medially shorter in the heel area and midfoot area than laterally and in the area of the bale medially longer than laterally. Due to the shape and position of the longitudinal slot, in particular the rolling characteristics of the sole construction can be influenced and adjusted.
Die nach unten offenen Vertiefungen zwischen den rinnenförmigen Elementen 21 sowie der Längsschlitz 22 erweitern sich vorzugsweise jeweils etwas nach unten, was dem Einklemmen beispielsweise von Steinen entgegenwirkt und die Selbstreinigung der Sohlenkonstruktion unterstützt. The downwardly open recesses between the channel-shaped elements 21 and the longitudinal slot 22 preferably each extend slightly downwards, which counteracts the pinching example of stones and supports the self-cleaning of the sole construction.
Zum Schutz der Sohlenkonstruktion gegen Abrasion sind die am stärksten belasteten rinnenförmigen Elemente 21 im Fersen- und im Ballenbereich mit dünnschichtigen Auflagen aus einem hartelastischen Material wie Gummi versehen, wobei in Fig. 2 nur eine dieser mit einer schrägen Rippung dargestellten Auflagen mit 30 bezeichnet ist. An den übrigen rinnenförmigen Elemente 21 ist das Material der Zwischensohle 20 direkt dem Bodenkontakt ausgesetzt. BEZUGSZEICH ENLISTE To protect the sole structure against abrasion, the most heavily loaded channel-shaped elements 21 are provided in the heel and ball area with thin layers of hard-elastic material such as rubber, wherein in Fig. 2, only one of these with an oblique ribbing shown pads 30 is designated. At the other channel-shaped elements 21, the material of the midsole 20 is exposed directly to the ground contact. REFERENCE LIST ENLIST
