  • French patent 2,220,128 provides not spikes, but spikes whose penetration into the ground is limited. These points cooperate in the first place with recesses which could be assimilated to suction cups but whose edges do not project from the sole and therefore cannot behave like the deformable lips according to the invention.
  • Said tips also cooperate with two types of projections called in the patent "first and second projections"; these projections (21 and 22, for example) do not at all resemble those of the invention because they are peduncles spaced from each other and arranged around the corresponding tip; these peduncles have in most cases the shape of small cylindrical lugs (21) or small points (22) or small notched bars (122); in any case, these projections seem rigid and undeformable instead of being flexible and flattenable as are the lips of the present invention.

Description

La présente invention concerne une semelle perfectionnée pour chaussures de sport, à saillies sous-jacentes de tenue sur le terrain, pour la pratique notamment du football, du rugby, du hockey sur gazon ou autres.The present invention relates to an improved sole for sports shoes, with underlying projections for holding on the ground, for the practice in particular of football, rugby, field hockey or others.

Actuellement, une telle semelle est spécifique à chaque nature de terrain et, si elle convient parfaitement pour jouer sur le terrain pour lequel elle a été conçue, elle ne donne évidemment pas satisfaction pour jouer sur les autres terrains.Currently, such a sole is specific to each type of terrain and, if it is perfectly suitable for playing on the terrain for which it was designed, it obviously does not give satisfaction for playing on other terrains.

Certaines semelles sont équipées de crampons métalliques interchangeables de hauteurs différentes (6 à 8) et conviennent pour des pelouses grasses ou tendres. D'autres semelles sont pourvues de crampons moulés (12 à 20) et sont différenciées suivant un échantillonnage adapté aux pelouse tendres à dures ou aux terrains stabilisés. Il existe aussi des semelles présentant-en saillie des crampons et des crans dont les situations mutuelles sont choisies pour satisfaire spécialement au jeu sur terrains stabilisés, éventuellement sur pelouse sèche ou gelée. D'autres semelles encore comportent un très grand nombre de petits crampons répartis au plus près les uns des autres pour jouer sur terrains synthétiques ou en salles.Some soles are fitted with interchangeable metal studs of different heights (6 to 8) and are suitable for oily or tender lawns. Other soles are provided with molded crampons (12 to 20) and are differentiated according to a sampling adapted to soft to hard lawns or stabilized grounds. There are also soles with protruding studs and notches, the mutual situations of which are chosen to specially satisfy the game on stabilized grounds, possibly on dry or frozen lawn. Still other soles have a very large number of small studs distributed as close as possible to each other for playing on synthetic pitches or in indoor courts.

Par conséquent, le footballeur, le rugbyman, le hockeyeur ... devrait disposer d'autant de paires de chaussures qu'il rencontrera de surfaces de jeu différentes durant la saison. Il est bien évident que, pour des raisons financières, les joueurs, dans leur grande majorité, ne peu- vant pas satisfaire à cette contrainte et se contentent d'une ou deux paires de chaussures seulement, de sorte que, durant la saison, ils ne peuvent pas mettre parfaitement et régulièrement en valeur leurs qualités de jeu.Consequently, the footballer, rugby player, hockey player ... should have as many pairs of shoes as he will encounter different playing surfaces during the season. It is quite obvious that, for financial reasons, the vast majority of players cannot meet this constraint and settle for only one or two pairs of shoes, so that during the season they cannot perfectly and regularly enhance their playing qualities.

La présente invention a pour but de remédier à ces inconvénients, en proposant une semelle polyvalente dont les saillies sous-jacentes pourront convenir, sous réserve de l'interchangeabilité de certaines, pratiquement à un jeu très satisfaisant sur tous les terrains, cette semelle étant en outre légère et très résistante à l'usure, plus souple que jusqu'à présent et cependant suffisamment rigide localement pour que le pied du joueur ne sente pas les saillies à travers la semelle proprement dite.The object of the present invention is to remedy these drawbacks by proposing a multi-purpose sole, the underlying projections of which may be suitable, subject to the interchangeability of some, practically a very satisfactory clearance on all terrains, this sole being in besides light and very resistant to wear, more flexible than so far and yet sufficiently rigid locally so that the player's foot does not feel the projections through the sole itself.

Conformément à l'invention, la semelle présente en saillie, en combinations avec les bossages taraudés coopérant sélectivement avec un échantillonnage diversifié de crampons, des lèvres saillantes déformables élastiquement et tendant lors de l'utilisation de la semelle à s'aplatir, les lèvres saillantes entourant concentriquement certains au moins des bossages taraudés; chacune s'amincit de sa base vers son extrémité libre, sa fibre neutre penchant du côte où elle doit s'aplatir, à l'opposé du bossage taraudé.In accordance with the invention, the sole projecting, in combination with the threaded bosses cooperating selectively with a diversified sampling of studs, projecting lips elastically deformable and tending when the sole is flattened, the projecting lips concentrically surrounding at least some of the threaded bosses; each thins from its base towards its free end, its neutral fiber leaning from the side where it must flatten, opposite to the threaded boss.

Pour illustrer l'arrière plan technologique, le brevet français 2220128 et le modèle d'utilité allemand 8 022 761 sont cités.To illustrate the technological background, French patent 2220128 and the German utility model 8 022 761 are cited.

Le brevet français 2 220 128 prévoit, non pas des crampons, mais des pointes dont la pénétration dans le sol est limitée. Ces pointes coopèrent en premier lieu avec des évidements qui pourraient être assimilés à des ventouses mais dont les bords ne font pas saillie de la semelle et ne peuvent par conséquent pas se comporter comme les lèvres déformables selon l'invention. Lesdites pointes coopèrent également avec deux types de saillies dénommées dans le brevet »premières et secondes saillies«; ces saillies (21 et 22, par exemple) ne ressemblent pas du tout à celles de l'invention car il s'agit de pédoncules écartés les uns des autres et disposés autour de la pointe correspondante; ces pédoncules présentent dans la plupart des cas la forme de petits ergots cylindriques (21) ou de petites pointes (22) ou de petites barrettes crantées (122); de toute façon, ces saillies semblent rigides et indéformables au lieu d'être souples et aplatissables comme le sont les lèvres de la présente invention.French patent 2,220,128 provides not spikes, but spikes whose penetration into the ground is limited. These points cooperate in the first place with recesses which could be assimilated to suction cups but whose edges do not project from the sole and therefore cannot behave like the deformable lips according to the invention. Said tips also cooperate with two types of projections called in the patent "first and second projections"; these projections (21 and 22, for example) do not at all resemble those of the invention because they are peduncles spaced from each other and arranged around the corresponding tip; these peduncles have in most cases the shape of small cylindrical lugs (21) or small points (22) or small notched bars (122); in any case, these projections seem rigid and undeformable instead of being flexible and flattenable as are the lips of the present invention.

En réalité, la semelle de ce brevet français est destinée à permettre aux coureurs et aux sauteurs de »s'accrocher« sans la détériorer à une piste élastique caoutchouteuse étanche, en évitant d'être victime, en cas de pluie, du phénomène »d'aquaplanning«; par contre, dans l'invention il s'agit pour le footballeur, le rugbyman, le hockeyeur ... de pouvoir évoluer dans les meilleures conditions avec une seule paire de chaussures sur des surfaces des jeu différentes durant toute la saison.In reality, the sole of this French patent is intended to allow runners and jumpers to "hang on" without damaging it on a waterproof rubbery elastic track, avoiding being a victim, in the event of rain, of the phenomenon "d 'aquaplanning'; on the other hand, in the invention it is a question for the footballer, the rugby player, the hockey player ... of being able to evolve in the best conditions with a single pair of shoes on different playing surfaces throughout the season.

Le modèle d'utilisé 8 022 761 décrit une semelle présentant des aspérités qui semblent destinées à placer des »tranchants« 16 à 21 à distance suffisante de la semelle. Ces aspérités sont rigides car la souplesse, lorsqu'elle est évoquée dans la description, concerne la semelle et les espace qui séparent lesdites aspérités. En d'autres termes, ces aspérités ne ressemblent absolument pas aux lèvres déformable et aplatissables de la présente invention. En outre, les aspérités sont parallèles entre elles et ne coopèrent pas avec des crampons.The model used 8 022 761 describes a sole with roughness which seems intended to place "cutting edges" 16 to 21 at a sufficient distance from the sole. These asperities are rigid because the flexibility, when it is mentioned in the description, concerns the sole and the spaces which separate said asperities. In other words, these asperities absolutely do not resemble the deformable and flattenable lips of the present invention. In addition, the asperities are parallel to each other and do not cooperate with studs.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention et des modes d'utilisation variés sont représentés, à titre d'exemples non limitatifs, sur le dessin annexé.An embodiment of the subject of the invention and various modes of use are shown, by way of nonlimiting examples, in the appended drawing.

Sur ce dessin:

  • - la figure 1 est une vue en plan de dessous d'une semelle conforme à l'invention;
  • - la figure 2 est une coupe longitudinale prise suivant le ligne II-II de la figure 1;
  • - les figures 3 à 5 sont des coupes transversales partielles prises à plus grande échelle suivant la ligne IV-IV de la figure 1 et montrant plusieurs modes d'utilisation de la semelle adaptés au terrain sur lequel le jeu doit être pratiqué;
  • - la figure 6 est un profil agrandi d'une lèvre saillante voisine d'un bossage, illustrant la conformation idéale.
On this drawing:
  • - Figure 1 is a bottom plan view of a sole according to the invention;
  • - Figure 2 is a longitudinal section taken along the line II-II of Figure 1;
  • - Figures 3 to 5 are partial cross sections taken on a larger scale along the line IV-IV of Figure 1 and showing several modes of use of the sole adapted to the terrain on which the game is to be played;
  • - Figure 6 is an enlarged profile of a projecting lip adjacent to a boss, illustrating the ideal conformation.

Ainsi que cela ressort clairement des figures 1 et 2, la semelle 1 est en matière plastique moulée. De préférence, cette matière est un élastomère de polyuréthane choisi par exemple parmi les élastomères thermoplastiques proposés à la vente par Bayer, BASF, Europolymeres, Goo- drich ...; elle peut aussi être sélectionnée parmi les produits de la nouvelle génération de copolymères polyéther ou polyester avec des polyamides, l'un de ces produits étant commercialisé par ATO sous la dénomination Pebax.As is clear from Figures 1 and 2, the sole 1 is molded plastic. Preferably, this material is a polyurethane elastomer chosen for example from the thermoplastic elastomers offered for sale by Bayer, BASF, Europolymers, Goodich ...; it can also be selected from the products of the new generation of polyether or polyester copolymers with polyamides, one of these products being marketed by ATO under the name Pebax.

De toute façon, le choix de ces matériaux est dicté par leurs propriétés particulièrement intéressantes que l'invention se propose d'exploiter. Ils possèdent une remarquable résistance à l'abrasion et sont facilement moulables en faible épaisseur; dès lors, la semelle peut être utilisée sur n'importe quel terrain, y compris sur ceux qui sont notablement abrasifs, et elle peut être très légère. Ces matériaux présentent une dureté Shore comprise entre 20 et 40, ainsi qu'un module élastique compris entre 100 et 200 NM par m2, de préférence égal à 150; par suite, la semelle est très souple et confortable, propriété qui, alliée à la légèreté, améliore la qualité du jeu, atténu la fatigue du joueur et rend le port de la chaussure ni douloureux ni contraignant; par contre, cette semelle manque de rigidité à l'endroit où, comme cela est indiqué dans ce qui suit, des inserts, de préférence métalliques et parfois en matière plastique, sont rendus prisonniers et pour annihiler ce défaut, en évitant ainsi que ces inserts ne se déchaussent et qu'ils ne soient sensibles au pied du joueur lors des contact violents de la semelle sur le terrain, une surépaisseur de ladite semelle est prévue au moins à ces endroits.In any case, the choice of these materials is dictated by their particularly advantageous properties which the invention proposes to exploit. They have remarkable resistance to abrasion and are easily moldable in small thicknesses; therefore, the sole can be used on any terrain, including those that are significantly abrasive, and it can be very light. These materials have a Shore hardness between 20 and 40, as well as an elastic modulus between 100 and 200 NM per m 2 , preferably equal to 150; as a result, the sole is very flexible and comfortable, a property which, combined with lightness, improves the quality of the game, reduces player fatigue and makes wearing the shoe neither painful nor restrictive; on the other hand, this sole lacks rigidity at the place where, as indicated below, inserts, preferably metallic and sometimes made of plastic, are taken captive and to eliminate this defect, thus avoiding these inserts do not take off and they are not sensitive to the player's foot during violent contact with the sole on the ground, an extra thickness of said sole is provided at least at these locations.

La semelle 1 présente un dessous 2 (figure 1 et 2) sensiblement plan dont le contour est adapté à celui du pied dans les parties antérieure 3 et postérieure 4, alors que, dans la partie intermédiaire 5 correspondant sensiblement à la cambrure, ce contour s'amincit progressivement en largeur; le contour aminci du dessous est raccordé au contour normal du dessus 6 dont la largeur est celle du pied, par des parties latérales en pente remontante arrondie 7, 8.The sole 1 has an underside 2 (FIGS. 1 and 2) substantially planar, the contour of which is adapted to that of the foot in the anterior 3 and posterior parts 4, while, in the intermediate part 5 corresponding substantially to the camber, this contour s '' gradually thins in width; the thinned outline of the bottom is connected to the normal outline of the top 6, the width of which is that of the foot, by lateral parts with a rounded upward slope 7, 8.

Ce dessus 6 (figure 2) est progressivement ascendant dans la partie intermédiaire 5 pour que la partie antérieure 3 relativement mince soit au niveau du bout du pied en appui normal de repos sur le sol, que la partie postérieure 4 globalement plus épaisse soit au niveau du talon dans cette position de repos la moins fatigante et que la partie intermédiaire 5 soit conformée suivant la cambrure du pied. Pour obtenir un tel dessus 6 sans alourdir la semelle, celle-ci présente des nervures longitudinales 9 et transversales 10 convenablement disposées et réparties pour recevoir la première de montage sans que celle-ci ne se déforme à l'usage et ne transmette au pied la géométrie du nervurage auquel ledit pied doit être insensible.This upper 6 (FIG. 2) is gradually ascending in the intermediate part 5 so that the relatively thin anterior part 3 is at the level of the end of the foot in normal rest support on the ground, that the generally thicker posterior part 4 is at the level of the heel in this least tiring rest position and that the intermediate part 5 is shaped according to the camber of the foot. To obtain such a top 6 without weighing down the sole, the latter has longitudinal 9 and transverse ribs 10 suitably arranged and distributed to receive the first mounting without the latter deforming in use and transmitting to the foot the geometry of the ribbing to which said foot must be insensitive.

Comme le montrent les figures 1 et 2, la semelle présente en saillie sur son dessous quatre bossages 11 dans la partie antérieure 3 et deux bossages 11 dans la partie postérieure 4; ces bossages sont beaucoup plus épais que le reste de la semelle (figures 3 à 5); dès lors, des inserts taraudés 12 de préférence métalliques sur lesquels ladite semelle est surmoulée se trouvent prisonniers desdits bossages dont la rigidité est accrue, en raison de leur surépaisseur, et suffisante pour que le pied du joueur ne puisse pas les sentir.As shown in Figures 1 and 2, the sole projecting from its underside four bosses 11 in the front part 3 and two bosses 11 in the rear part 4; these bosses are much thicker than the rest of the sole (Figures 3 to 5); therefore, threaded inserts 12 preferably metallic on which said sole is molded are trapped in said bosses whose rigidity is increased, due to their extra thickness, and sufficient for the player's foot can not feel them.

Chaque bossage 11 (figures 3 à 5) est entouré par une gorge annulaire 13 et son insert taraudé 12 débouche sur une face circulaire centrale 14 reliée à la gorge par un épaulement coronal épaulé et cranté 15.Each boss 11 (FIGS. 3 to 5) is surrounded by an annular groove 13 and its threaded insert 12 opens onto a central circular face 14 connected to the groove by a shouldered and notched coronal shoulder 15.

Chaque bossage coopère avec des lèvres saillantes 16 déformables élastiquement et tendant à s'aplatir, comme cela apparaît sur la figure 3 en comparant la position de repos représentée en trait plein avec l'une des positions de sollicition illustrée en trait pointillé.Each boss cooperates with projecting lips 16 which are elastically deformable and tend to flatten, as appears in FIG. 3 by comparing the rest position shown in solid lines with one of the stress positions illustrated in dotted lines.

Dans l'exemple représenté sur la figure 1, les lèvres 16 combinées à un même bossage sont arquées concentriquement à celui-ci.In the example shown in Figure 1, the lips 16 combined with the same boss are arcuate concentrically thereto.

Lorsqu'il s'agit de la partie antérieure 3, ces lèvres sont au nombre de trois et chacune un secteur angulaire, sensiblement égal à 90; elles sont séparées l'une de l'autre, du côte de l'axe médian de la semelle, par des fentes 17 et, du côté périphétique, par un très large évidement 18 pour que le bossage 11 et les deux lèvres qui lui sont diamétralement opposées soient situés au plus près du bord de la semelle.When it comes to the front part 3, there are three of these lips and each one has an angular sector, substantially equal to 90; they are separated from each other, on the side of the median axis of the sole, by slots 17 and, on the periphery side, by a very large recess 18 so that the boss 11 and the two lips which are attached to it diametrically opposite are located closest to the edge of the sole.

Lorsqu'ils s'agit de la partie postérieure 4, lesdites lévres (16) ne sont qu'au nombre de deux et sont séparées les unes des autres pour les deux bossages par des évidements pérépheriques 18 et un évidement médian commun 19. Ainsi, ces lèvres sont situées au plus près des bords de la semelle et occupent la surface la plus grande.When it is a question of the posterior part 4, said lips (16) are only two in number and are separated from each other for the two bosses by perepherical recesses 18 and a common median recess 19. Thus, these lips are located as close as possible to the edges of the sole and occupy the largest surface.

Il résulte de l'exposé qui précède que certaines lèvres peuvent se coucher, lorsqu'elles sont sollicitées, dans la direction antéroposté- rieure et, d'autres, dans la direction transversale.It follows from the foregoing description that certain lips can lie down, when they are pressed, in the anteroposterior direction and others in the transverse direction.

Ces lèvres 16 sont séparées des bossages correspondants 11 par les gorges annulaires 13 et elles s'amincissent de leur base vers leur extrémité libre. Dans l'exemple illustré par les figures 3 à 5 et favorable au démoulage, chaque lèvre 16 est délimitée par une paroi extérieure 20 perpendiculaire à la semelle, par une paroi intérieure 21 incurvée en inclinaison vers l'extérieur du bossage 11 correspondant et en s'écartant du dessous 2 de la semelle et par une crête arrondie 22. La fibre neutre de la lèvre 16 considérée penche donc du côte où cette lèvre doit s'aplatir, c'est-à-dire à l'opposé du bossage 11 précité. L'idéal pour favoriser ce fléchissement et son orientation est que le profil de chaque lèvre soit celui représenté sur la figure 6; dans ce cas, la lèvre est délimitée également par une paroi extérieure 23 en pente incurvée comme la paroi intérieure 21.These lips 16 are separated from the corresponding bosses 11 by the annular grooves 13 and they become thinner from their base towards their free end. In the example illustrated by FIGS. 3 to 5 and favorable to demolding, each lip 16 is delimited by an external wall 20 perpendicular to the sole, by an internal wall 21 curved in inclination towards the outside of the corresponding boss 11 and in s 'deviating from below 2 of the sole and by a rounded ridge 22. The neutral fiber of the lip 16 considered therefore leans to the side where this lip must flatten, that is to say opposite to the aforementioned boss 11 . The ideal way to promote this deflection and its orientation is for the profile of each lip to be that shown in FIG. 6; in this case, the lip is also delimited by an outer wall 23 in a curved slope like the interior wall 21.

Par ailleurs et pour que l'aplatissement élastique des lèvres s'effectue dans de bonnes conditions, celles-ci font saillie du dessous 2 de la semelle au-delà de la face libre 14 des bossage 11 correspondants; de préférence, la distance d de la crête 22 des lèvres à la face 14 des bossages, lorsque ces lèvres sont au repos, est comprise entre 2 et 5 mm.Furthermore and so that the elastic flattening of the lips takes place in good conditions, they protrude from the underside 2 of the sole beyond the free face 14 of the corresponding bosses 11; preferably, the distance d from the crest 22 of the lips to the face 14 of the bosses, when these lips are at rest, is between 2 and 5 mm.

Bien entendu, il y a avantage à ce que les lèvres soient arquées mais il n'est pas impératif qu'elles soient centrées sur les bossages et cela peut être intéressant pour mieux les répartir sur le dessous 2 de la semelle et occuper l'espace à l'endroit qui convient le mieux. D'autre part, certains bossages peuvent être exempts de lèvres.Of course, there is an advantage in that the lips are arched but it is not imperative that they are centered on the bosses and this can be interesting to better distribute them on the underside 2 of the sole and occupy the space where it works best. On the other hand, some bosses can be free of lips.

En outre, et ainsi que cela ressort des figures 1 et 2, la semelle 1 peut présenter en saillie sur son dessous 2 des crans transversaux de retenue 24 et 25 situés de préférence en bout avant et respectivement en bout arrière; de plus, elle peut comporter des languettes incurvées longitudinales 26 s'étendant en saillie sur la partie intermédiaire 5 du dessous 2; elle peut encore présenter en creux des rainures transversales 27 favorisant la pliure de la semelle en correspondance avec l'articulation du bout du pied.In addition, and as is apparent from Figures 1 and 2, the sole 1 may have projecting on its underside 2 transverse retaining notches 24 and 25 preferably located at the front end and respectively at the rear end; in addition, it may include longitudinal curved tongues 26 projecting from the intermediate part 5 from below 2; it may also have hollow transverse grooves 27 promoting the folding of the sole in correspondence with the articulation of the end of the foot.

Le joueur dispose normalement d'un échantillonnage de crampons et, dans le cas présent, cela est nécessaire pour équiper suivant la nature du terrain les bossages taraudés 11.The player normally has a sample of studs and, in this case, this is necessary to equip the threaded bosses 11 according to the nature of the terrain.

S'il s'agit de jouer sur une pelouse ou un terrain gras, le joueur monte des crampons métalliques destinés à pénétrer plus ou moins dans le sol, tout en permettant aux lèvres 16 de s'aplatir plus ou moins. Pour respecter cet impératif, il choisit alors des crampons courts 28 ou des crampons moyens 29 ou bien des crampons hauts 30 (figure 4); les crampons sélectionnés sont vissés par leur queue filetée 31 dans l'insert correspondant 12 jusqu'à ce que le fond 32 de la cuvette de base de leur tête bute contre la face 14 du bossage conjugué 11 et que la collerette annulaire périphérique de base 33 de leur tête écrase les crans de l'épaulement 15 de ce bossage.If it is a question of playing on a lawn or a greasy ground, the player mounts metal cleats intended to penetrate more or less into the ground, while allowing the lips 16 to flatten more or less. To comply with this requirement, he then chooses short spikes 28 or medium spikes 29 or else high spikes 30 (Figure 4); the selected studs are screwed by their threaded tail 31 into the corresponding insert 12 until the bottom 32 of the base cup of their head abuts against the face 14 of the conjugate boss 11 and that the basic peripheral annular collar 33 of their head crushes the notches of the shoulder 15 of this boss.

S'il s'agit de jouer sur un terrain gelé, le joueur monte des crampons de grand diamètre 34 en polyuréthane, offrant une surface de contact au sol suffisamment grande pour que les lèvres 16 ne s'aplatissent pas (figure 5). La queue filetée 35 de ces crampons est alors vissée dans l'insert correspondant 12 jusqu'à ce que la collerette périphérique saillante 36 de ces crampons s'écrase et s'appuie solidement contre le fond de la gorge annulaire 13 entourant le bossage conjugué 11.If it is a question of playing on frozen ground, the player mounts large diameter spikes 34 in polyurethane, providing a contact surface with the ground large enough so that the lips 16 do not flatten (FIG. 5). The threaded tail 35 of these studs is then screwed into the corresponding insert 12 until the projecting peripheral flange 36 of these studs is crushed and bears firmly against the bottom of the annular groove 13 surrounding the conjugate boss 11 .

S'il s'agit de jouer sur un terrain dur, seules les lèvres 16 doivent intervenir en s'aplatissant et le joueur s'abstient alors de monter des crampons; cependant, pour éviter l'obstruction des trous taraudés par la terre, les brins d'herbe ..., ceux-ci sont obturés par des bouchons 37 (figure 3).If it is a question of playing on hard ground, only the lips 16 must intervene by flattening and the player then refrains from mounting crampons; however, to avoid obstruction of the tapped holes by the ground, the blades of grass ..., these are closed by plugs 37 (Figure 3).

L'invention n'est pas limitée à la forme de réalisation représentée et décrite en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiment shown and described in detail, because various modifications can be made without departing from its scope.
