Description

BANDE ANTIDERAPANTE NON-SLIP TAPE
On cherche depuis longtemps à réaliser des bandes présentant sirmultané ment les qualités suivantes :It has been sought for a long time to produce tapes having the following qualities:
-une bonne adhérence, c'est-à-dire un contact très intime avec les surfaces contre lesquelles elles sont appliquées, -un pouvoir antidérapant élevé, c'est-à-dire une forte résistance à toute action qui tend à les faire glisser ou déraper sur ces surfaces, -une forte résistance à l'usure lorsque ces actions, conjuguées ou non, se répètent fréquernnent. L'adhérence et le pouvoir antidérapant sont évidemment des propriétés étroitement liées qui dépendent des états de surfaces en présence, des gradients de pression, etc.-a good adhesion, that is to say a very intimate contact with the surfaces against which they are applied, -a high non-slip power, that is to say a strong resistance to any action which tends to make them slide or slip on these surfaces, -a strong resistance to wear when these actions, combined or not, are repeated frequently. Adhesion and non-slip properties are obviously closely related properties which depend on the surface conditions present, pressure gradients, etc.
Les surfaces antidérapantes réalisées jusqu'à ce jour ont été obtenues avec des matériaux naturellement rugueux (caoutchouc, crêpe, etc.) ou présentant des aspérités artificielles rigides ou souples, pleines ou creuses, telles que des crampons, des clous, des taquets, des dents, qui accrochent les inégalités des surfaces avec lesquelles elles sont mises en contact.The non-slip surfaces produced to date have been obtained with materials which are naturally rough (rubber, crepe, etc.) or which have rigid or flexible, full or hollow asperities, such as crampons, nails, cleats, teeth, which catch the unevenness of the surfaces with which they are contacted.
La présente invention a pour objet une bande présentant des qualités d'adhérence et antidérapantes exceptionnelles. Cette bande, qui emporte des aspérités creuses en relief, est caractérisée par le fait que l'épaisseur desdites aspérités d écro it d e leur base à leur scπimet de manière que leur base offre une forte résistance à toute action mécanique qui tend à les déformer tandis que leur partie supérieure forma une m≈mbrane élastique . Le dessin ci-annexë représente, a titre d'exemple, deux formes d'exécution de l'objet de l'invention constituant respectivement une bande de roulement de pneumatique et une semelle de chaussure. La figure 1 est une vue en coupe de la bande de roulement, la figure 2 en est une vue partielle en plan, la figure 3 est une vue en gros plan en coupe d'une aspérité, les figures 4 et 5 sont des vues analogues à la figure 3 illustrant le comportant de l'aspérité sous l'action de diverses forces.The present invention relates to a strip having exceptional adhesion and non-slip qualities. This strip, which carries hollow asperities in relief, is characterized by the fact that the thickness of said asperities decreases from their base to their scπimet so that their base offers strong resistance to any mechanical action which tends to deform them while that their upper part formed an elastic m≈mbrane. The accompanying drawing shows, by way of example, two embodiments of the subject of the invention constituting respectively a tire tread and a shoe sole. Figure 1 is a sectional view of the tread, Figure 2 is a partial plan view, Figure 3 is a close-up sectional view of an asperity, Figures 4 and 5 are similar views in Figure 3 illustrating the asperity under the action of various forces.
La figure 6 est une vue par-dessous de la semelle, la figure 7 en est une vue en coupe par la Ligne VII-VII de la figure 6. La bande de roulement représentée aux figures 1 à 5 est constituée par un manteau 10 recouvert d'une enveloppe 11, en caoutchouc naturel ou synthétique, présentant une pluralité d'aspérités 12 cr eus es réparties régulièrement (surface S1). L'épaisseur des parois des aspérités décroît régulièrement de leur base à leur sαrmet de manière à offrir à leur naissance une forte résistance à toute action mécanique qui tend à les déformer et qu'à partir d'une certaine hauteur la paroi forme une membrane élastique 13. Lorsque cette bande est appliquée par une force normale F contre une surface S (figure 4), les membranes élastiques 13 se déforment en épousant localement les inégalités de la surface S2 tandis que les bases des aspérités développent une réaction résultante qui équilibre la force Fn.Figure 6 is a view from below of the sole, Figure 7 is a sectional view through the Line VII-VII of Figure 6. The tread shown in Figures 1 to 5 is constituted by a coat 10 covered an envelope 11, made of natural or synthetic rubber, having a plurality of hollow asperities 12 regularly distributed (surface S 1 ). The thickness of the walls of the asperities decreases regularly from their base to their sαrmet so as to offer at birth a strong resistance to any mechanical action which tends to deform them and that from a certain height the wall forms an elastic membrane 13. When this strip is applied by a normal force F against a surface S (FIG. 4), the elastic membranes 13 deform by locally matching the unevenness of the surface S 2 while the bases of the asperities develop a resulting reaction which balances the force F n .
Si la bande est soumise non seulement à une force normale Fn mais encore à une force tangentielle Ft qui tend à faire glisser les surfaces S1 et S2 l'une sur l'autre (figure 5), les membranes élastiques 13 s'agrippent aux inégalités de la surface S2 en même temps que leurs bases opposent, en s'arqueboutant, une forte résistance à l'action de dérapage de la force Ft .If the strip is subjected not only to a normal force F n but also to a tangential force F t which tends to make the surfaces S 1 and S 2 slide one on the other (FIG. 5), the elastic membranes 13 s 'grip the unevenness of the surface S 2 at the same time as their bases oppose, by arching, a strong resistance to the skidding action of the force F t .
La bande de roulement décrite assure une execellente tenue de route sur tous les genres de sols et une très grande efficacité lors des freinages. La semelle représentée aux figures 6 et 7 est constituée par une plaque 20, en matériau naturel ou synthétique, sur laquelle est collée une bande 21, souple et élastique, présentant des aspérités creuses 22. L'épaisseur des aspérités décroit de manière régulière de leur base à leur sαrmet de manière à offrir jusqu' à une certaine hauteur "une forte résistance à toute action mécanique qui tend à les déformer, tandis qu'à partir de cette hauteur, la paroi est assimilable à une membrane élastique. Des trous 23 prévus au sαπmεt des aspérités permettent à de l'air de s'écouler de l'intérieur vers l'extérieur et inversement.The tread described ensures excellent road holding on all types of ground and very high efficiency during braking. The sole shown in Figures 6 and 7 consists of a plate 20, of natural or synthetic material, on which is glued a strip 21, flexible and elastic, having hollow asperities 22. The thickness of the asperities decreases steadily in their base to their sαrmet so as to offer up to a certain height "a strong resistance to any mechanical action which tends to deform them, while from this height, the wall is comparable to an elastic membrane. Holes 23 provided rough edges allow air to flow from the inside to the outside and vice versa.
Lorsque la semelle est pressée contre une surface irrégulière, les aspérités 22 se défornent, carme illustré aux figures 3 à 5, puis reprennent leurs formes initiales lorsque la pression cesse. Ce cas se distingue du précédent par le fait que durant l'intervalle de temps pendant lequel la pression s'exerce, de l'ait s'échappe à travers les trous 23. Il en résulte que les membranes épousent plus rapidement le relief de la surface contre laquelle la semelle est appliquée que dans le cas où il n'y pas de trous. On augmente ainsi dans des proportions notables l'effet antidérapant. De plus, l'air qui est ainsi puisé chasse les particules, les grains de sable ou de gravier ou encore la pellicule grasse ou liquide qui recouvrent le sol et qui favorisent les glissades et les dérapages. Bien qu'un effet anti-choc ne soit pas spécialement recherché, on observe qu'il existe et qu' il se superpose à l'effet anti-dérapant . La semelle décrite allie"ainsi un confort appréciable à une sécurité totale.When the sole is pressed against an irregular surface, the asperities 22 are deformed, as shown in FIGS. 3 to 5, then resume their initial forms when the pressure ceases. This case is distinguished from the previous one by the fact that during the time interval during which the pressure is exerted, air escapes through the holes 23. As a result, the membranes marry more quickly the relief of the surface against which the soleplate is applied only in the case where there are no holes. This increases the anti-slip effect in significant proportions. In addition, the air which is thus drawn out drives out particles, grains of sand or gravel or even the oily or liquid film which covers the ground and which promotes slips and slips. Although an anti-shock effect is not specially sought, it is observed that it exists and that it is superimposed on the anti-slip effect. The sole described thus "combines appreciable comfort with total security.
Les trous 23 pourraient être situés ailleurs qu'au sαimet des aspérités sans que l'effet anti-dérapant obtenu soit modifié. The holes 23 could be located elsewhere than in the rough surface without the anti-slip effect obtained being modified.
