i 5 Opfindelsen angår en sko, fortrinsvis en løbesko, bestående af en sålenhed med bindsål og en slidsål samt en dertil fastgjort overdel, hvor sålenheden yderligere er forsynet med på tværs af skoens akselinie forløbende fjedrende ribber, der er placeret mellem 10 bindsålen og slidsålen og danner en vinkel med bindsålens overflade.The invention relates to a shoe, preferably a running shoe, consisting of a sole unit with a sole and a wearing sole, and a top attached thereto, the sole unit being further provided with resilient ribs extending transversely of the shaft line, located between the sole of the sole and the wear sole. forming an angle with the surface of the insole.

Hidtil kendte løbesko af denne art er forsynet med en sål, som er mere eller mindre eftergivelig. Dette 15 sker fortrinsvis ved hjælp af en pude anbragt mellem bindsålen og slidsålen. Puden er fortrinsvis fremstillet af skumplast, som fungerer som en støddæmper for foden, som i en bevægelsescyklus ved nedslaget skal overføre vægten fra kroppen.Hitherto known running shoes of this kind are fitted with a sole which is more or less resilient. This is preferably done by means of a cushion placed between the sole and the wear sole. The cushion is preferably made of foam, which acts as a shock absorber for the foot, which in a movement cycle during the impact must transfer the weight from the body.

20 Sådanne puder fungerer som passiv-støddæmpere, der alene har til formål at beskytte fodens og benets knogler og led samt blodlegemerne, som navnlig i hælnedslaget er udsat for et stort tryk.20 Such cushions act as passive shock absorbers for the sole purpose of protecting the bones and joints of the foot and leg as well as the blood cells, which are subjected to high pressure, especially in the heel strike.

Dette passive dæmpningssystem giver en udmærket kontakt mellem fodsålen og skobunden, idet foden vil synke lidt ned i sålen, således at fladetrykket bliver mindst muligt.This passive cushioning system provides excellent contact between the sole of the foot and the shoe bottom, as the foot will sink slightly into the sole so that the surface pressure becomes as low as possible.

Desuden kendes en sko med fjedrende såler, hvor fjedervirkningen skyldes ribber på tværs af sålen. Sådanne ribber trykkes under gang en smule sammen, hvilket giver en blød og fjedrende gang. Dette komFurthermore, a shoe with resilient soles is known in which the spring effect is due to ribs across the sole. Such ribs are compressed slightly over time, providing a soft and resilient gait. This came

2 pressionsprincip er ikke hensigtsmæssigt til løbesko, idet sålen nødvendigvis bliver temmelig tyk, hvis en passende fjedervirkning skal opnås ved sammentrykning af ribberne.2 compression principle is not suitable for running shoes, since the sole necessarily becomes rather thick if an appropriate spring action is to be obtained by compressing the ribs.

Det er opfindelsens formål at forbedre en sål af den nævnte type, således at dens gode egenskaber bevares samtidig med, at den kan udformes lettere og dermed mere behagelig. Sålen skal have lavt fladetryk og 10 passende støddæmpning og skal udnytte sammentrykningen af sålen som et energitilskud i afsættet.It is the object of the invention to improve a sole of the said type so that its good properties are retained while being easier to design and thus more comfortable. The sole must have low surface pressure and adequate shock absorption and must utilize the compression of the sole as an energy supplement in the outlet.

Dette opnås ved, at ribberne forløber skråt bagud mod bindsålen i skoens fremføringsretning. Ved hjælp af 15 disse fjedrende ribber bevares den støddæmpende og kontaktskabende egenskab ved sålen. Idet ribberne er anbragt på sålen og peger bagud opnås, at sålen ikke behøver have samme tykkelse som tidligere kendte såler for at opnå en given fjedervirkning. Dette har 20 betydning ved løbesko, der jo ønskes så lette som muligt. Sålen ifølge opfindelsen opnår nemlig sin fjedervirkning ved hjælp af udspænding og ikke ved kompression, således at der kan opnås en god fjedervirkning af en tynd sål.This is accomplished by the ribs extending obliquely toward the sole of the shoe in the direction of feeding of the shoe. With the aid of these resilient ribs, the shock-absorbing and contact-forming property of the sole is retained. As the ribs are positioned on the sole and pointing backwards, it is achieved that the sole need not have the same thickness as previously known soles to achieve a given spring effect. This has 20 significance for running shoes, which are as easy as possible. Namely, the sole of the invention achieves its spring action by tension and not by compression, so that a good spring effect of a thin sole can be obtained.

Idet sålens fjederegenskaber fremkommer ved udspænding af ribberne opnås endvidere en meget effektiv fjedring. Dette bevirker, at sålen kan gøres meget let i forhold til såler, hvor fjedervirkningen opstår 30 på grund af sammentrykning af ribberne.Furthermore, as the spring properties of the sole are obtained by stretching the ribs, a very effective suspension is obtained. This means that the sole can be made very light compared to soles where the spring action occurs due to compression of the ribs.

Ved at give ribberne en hældning på ca. 40°, som omhandlet i krav 2, opnås en særdeles god fjederfunktion.By giving the ribs a slope of approx. 40 °, as claimed in claim 2, a very good spring function is achieved.

Endelig er det, som omhandlet i krav 3, fordelagtigt at fremstille sålen i et polyurethanmateriale på æ-terbasis, hvorved der dannes en sej ribbeoverflade, 5 som øger ribbernes fjedrende egenskaber.Finally, as claimed in claim 3, it is advantageous to fabricate the sole in an ether-based polyurethane material, thereby forming a tough rib surface 5 which enhances the resilient properties of the ribs.

Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvor 10 fig. 1 viser venstre sålenhed set fra oven, fig. 2 viser et snit II-II i fig, 1, og fig. 3 viser i snit III-III i fig. 1 og 2.The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a top view of the left sole unit, FIG. 2 shows a section II-II of FIG. 1; and FIG. 3 shows in section III-III of FIG. 1 and 2.

Som vist på fig. 1, der forestiller en venstre skosål set ovenfra, har sålen en fodformet ydre kontur. På langs af sålen forløber dens akselinie a-a. Endvidere er med skravering vist de zoner, hvor foden trykker 20 mod sålen, nemlig bagtil hælbalden 5, fortil storetå-balden 8 og fodbalden 7 samt forbindelsen mellem disse zoner, den såkaldte landtange 6.As shown in FIG. 1, depicting a left shoe sole seen from above, the sole has a foot-shaped outer contour. Along the sole, its axis line a-a extends. In addition, shading shows the zones where the foot presses 20 towards the sole, namely the heel heel 5, the front toe ball 8 and the foot 7 and the connection between these zones, the so-called shingles 6.

På tværs af akselinien a-a forløber i hele skoens 25 længde et antal parallelle ribber 1, som antydet med stiplet linie. Endelig ses med kraftig stiplet linie fodens afviklingslinie 4, der forløber fra hælbalden 5, over landtangen 6 tværs over tåbalden 7 og gennem tåbalden 8.Across the axis line a-a the entire length of the shoe 25 extends a number of parallel ribs 1, as indicated by a dotted line. Finally, with a strongly dashed line, the unwinding line 4 of the foot extending from the heel bale 5 is seen across the shore 6 across the toe bale 7 and through the toe bale 8.

30 Sålenheden er vist på fig. 2, der viser et snitbillede gennem sålen på fig. 1 set i retning II-II. Foroven har sålen en bindsål 3, der kan være af læder eller lignende.30 The sole unit is shown in FIG. 2, showing a sectional view through the sole of FIG. 1 seen in direction II-II. Above, the sole has a binding sole 3 which may be made of leather or the like.

Under denne er der en ribbesål, som på undersiden er forsynet med et antal tværløbende udsparinger, der danner de tværgående indbyrdes parallelle ribber 1.Below this there is a ribbed sole, which is provided on the underside with a number of transverse recesses forming the transversely parallel ribs 1.

5 Disse ribber har en hældning på omkring 40° med bindsålen, men denne vinkel kan varieres, som det senere vil blive forklaret. Endelig er der til ribbesålen fastgjort en slidsål 2.5 These ribs have a slope of about 40 ° with the sole, but this angle can be varied, as will be explained later. Finally, a wear sole 2 is attached to the rib sole.

10 På fig. 3 er vist et snitbillede på tværs af sålen set i retning III-III på fig. 1 og 2. Det ses, at slidsålen 2 fortsætter opad omkring ribbesålen og omslutter denne. Slidsålen er hele vejen rundt om sålen afrundet langs ydersiden 11, som vist på fig. 3.10 In FIG. 3 is a cross-sectional view of the sole seen in the direction III-III of FIG. 1 and 2. It is seen that the wear sole 2 continues upward around the rib sole and encloses it. The wear sole is rounded all the way around the sole along the outer surface 11, as shown in FIG. Third

Ribbesålen er fortrinsvis fremstillet ved støbning i polyurethan på æterbasis. Herved får ribberne på o-verfladen en sej hinde, som virker fremmende på ribbernes fjedrende egenskaber, som det senere vil blive 20 forklaret.The rib sole is preferably made by ether-based polyurethane casting. In this way, the ribs on the o-surface get a tough membrane which promotes the resilient properties of the ribs, as will be explained later.

Sålen er konstrueret med maksimal kontaktflade mellem fodsål og skobund, hvilket givet det mindste fladetryk. Endvidere vil sålens almindelige eftergivelig-25 hed ved belastning bevirke, at fodsålens kontaktflade med skobunden som helhed forøges, da foden synker mere eller mindre ned i sålen. Endvidere giver ribberne med luftmellemrum en forøgelse af sålens sammenpresselighed, og der akkumuleres maksimal energi i de 30 sammenpressede ribber.The sole is designed with maximum contact surface between the sole of the foot and the shoe bottom, which gives the least surface pressure. Furthermore, the general resilience of the sole under load will increase the contact surface of the foot sole with the shoe bottom as a whole as the foot sinks more or less into the sole. Furthermore, the air-spaced ribs increase the compressibility of the sole, and maximum energy accumulates in the 30 compressed ribs.

Da luftmellemrummet mellem ribberne således sammenpresses og udvides kan man ved at forsyne mellemrummet med en eller flere kanaler eller åbninger 12, seThus, since the air gap between the ribs is compressed and widened, one can provide one or more channels or openings 12, see

5 fig. 2, der passerer bindsålen 3, opnås en effektiv ventilation af skoen, idet luften vil blive presset op under fodsålen ved ribbernes sammentrykning. Sådanne ventilationsåbninger kan anbringes jævnt for-5 delt over hele sålen eller i bestemte zoner efter behov.5 FIG. 2, passing through the insole 3, effective ventilation of the shoe is achieved as the air will be compressed under the foot sole by the compression of the ribs. Such ventilation openings may be evenly distributed throughout the sole or in specific zones as required.

Ribbernes hældning bevirker, at de kan sammenpresses ved fodens nedad- og bagudrettede tryk, for derpå i 10 afsætsfasen at blive udløst i form af en slags fjedervirkning.The inclination of the ribs allows them to be compressed at the downward and backward pressure of the foot, to be released during the deposition phase in the form of a kind of spring action.

Denne sammentrykning af ribberne, og dermed akkumulering af energi, vil i fodens afsætsfase udløses og 15 give et bevægelsestilskud til afsættet som først ophører, når ribben har indtaget den ubelastede stilling.This compression of the ribs, and thus the accumulation of energy, will be triggered during the deposition phase of the foot and provide a movement supplement to the deposition which ceases only when the rib has taken the unloaded position.

Endvidere sammenpresses ribberne i en successiv bevæ-20 gelse fra hælen mod tåen, hvilket vil fremkalde en bølgebevægelse i bindsålen, som virker kredsløbsfremmende på fodsålen.Furthermore, the ribs are compressed in a successive movement from the heel to the toe, which will cause a wave movement in the sole which acts as a circuit enhancer on the foot sole.

Ved dimensionering af ribberne skal der tages hensyn 25 til fodens afviklingslinie, idet ribbehøjden er en af de faktorer, som bestemmer fjederfunktionen. Yderligere faktorer er afstanden mellem ribberne og deres vinkel a. Endvidere betyder materialets elasticitet også noget.When sizing the ribs, consideration should be given to the winding line of the foot, the rib height being one of the factors determining the spring function. Further factors are the distance between the ribs and their angle a. Furthermore, the elasticity of the material also matters.

Dette kan udnyttes til at give foden jie bedst mulige arbejdsvilkår, herunder at understøtte fodens torsionsfunktion under fodens isætning og afsæt. Denne funktion betyder, at foden styres gennem den på fig.This can be utilized to give the foot the best possible working conditions, including supporting the torsion function of the foot during insertion and starting of the foot. This function means that the foot is guided through the one shown in FIG.

6 1 stiplede afviklingslinie 4. Således er ribbehøjden 9 på fig. 3 i højre side større end i venstre side 10. Dette betyder, at ribberne omkring afviklingslinien 4 kan have en ribbehøjde 9 på for eksempel 18 mm 5 mens ribbehøjden 10 iøvrigt kan være for eksempel 15 mm. Herved bliver der større eftergivelighed og affjedring omkring afviklingslinien end ved den øvrige del af sålen.6 1 is a dotted winding line 4. Thus, the rib height 9 in FIG. 3 on the right side larger than on the left side 10. This means that the ribs around the unwinding line 4 may have a rib height 9 of, for example, 18 mm 5, while the rib height 10 may otherwise be, for example, 15 mm. This results in greater resilience and suspension around the settlement line than at the other part of the sole.

10 Ved en sål ifølge opfindelsen er der skabt betingelser som svarer til den bedste udnyttelse af musklernes fjederfunktion. Dette kan udnyttes af folk med for eksempel stillestående arbejde, hvor kroppen kan forskydes fremad og bagud i ankelledet med aktive 15 ryg- og lægmuskler og fuld aktivitet i tæerne, idet fødderne kan "gå" i sålen.In a sole according to the invention, conditions are created which correspond to the best utilization of the spring function of the muscles. This can be utilized by people with, for example, stagnant work, where the body can be moved forward and backward in the ankle joint with active back and leg muscles and full activity in the toes, as the feet can "walk" in the sole.
