Description
CHAUSSON D'ESCALADE COMPORTANT UN INSERT DE RENFORTCLIMBING SHOE HAVING REINFORCEMENT INSERT
L' invention se rapporte au domaine des chaussons d' escalade. The invention relates to the field of climbing shoes.
Les chaussons d'escalade presentent une semelle relativement simple constituee pour l'essentiel d'une semelle externe en materiau tres adherent, generalement a base de caoutchouc. Le document US-5,142,797 decrit un chausson d'escalade dans lequel la semelle comporte une semelle interne et une semelle externe, la semelle interne etant realisee en un materiau relativement rigide. Cette semelle interne presente une cambrure particuliere pour soulager les muscles de la voute plantaire lorsque le grimpeur est en appui par la pointe du chausson. Cette semelle interne relativement rigide vise done a modifier les caracteristiques de flexion de la Climbing shoes have a relatively simple sole consisting essentially of an outer sole of very adherent material, generally based on rubber. Document US Pat. No. 5,142,797 describes a climbing shoe in which the sole has an inner sole and an outer sole, the inner sole being made of a relatively rigid material. This insole has a special arch to relieve the arch muscles when the climber is supported by the tip of the shoe. This relatively rigid insole therefore aims to modify the flex characteristics of the
semelle sur sa longueur.sole along its length.
L'invention a pour but de proposer un chausson d'escalade qui presente notamment des caracteristiques ameliorees de resistance en torsion. En effet, tres souvent, le grimpeur est amene a prendre des appuis non pas par le bout du chausson, mais par les bords lateraux de la partie avant de la semelle, du cote interne ou du cote externe, que l'on appelle aussi les carres du chausson. Un tel appui, nettement decale par rapport a l'axe du pied et du chausson, tend done a provoquer une torsion (ou vrillage) du pied et du chausson autour de leur axe longitudinal. Dans ce but, ['invention propose un chausson d'escalade comportant une semelle en materiau adherent, caracterise en ce que le chausson comporte un insert de renfort dont le The object of the invention is to provide a climbing shoe which in particular has improved torsional strength characteristics. Indeed, very often, the climber is brought to take supports not by the end of the slipper, but by the lateral edges of the front part of the sole, on the internal or external side, which are also called the liner edges. Such support, clearly offset from the axis of the foot and the liner, therefore tends to cause a twist (or twist) of the foot and the liner around their longitudinal axis. To this end, the invention provides a climbing shoe comprising a sole of adherent material, characterized in that the shoe includes a reinforcing insert, the
contour coincide, au moins dans une partie avant de la semelle, avec le contour de la semelle. contour coincides, at least in a front part of the sole, with the contour of the sole.
D'autres caracteristiques et avantages de ['invention appara^tront a la lecture de la Other characteristics and advantages of the invention will appear on reading the
description detaillee qui suit, ainsi qu'au vu des dessins annexes dans lesquels: detailed description which follows, as well as in light of the annexed drawings in which:
- la figure 1 est une vue schematique en perspective d'un chausson muni d'un insert de 2 5 renfort conformement aux enseignements de ['invention; - la figure 2 illustre, en plan, un premier exemple de realisation d'insert de renfort, - la figure 3 est une vue similaire a celle de la figure 2 illustrant un insert muni d'un orifice central; - la figure 4 illustre un insert qui est de plus pourvu d'un contrefort arriere integre; 3 0 - la figure 5 est une vue partielle en coupe transversale du chausson de la figure 1; - les figures 6 et 7 illustrent en plan deux autres variantes de realisation d'un insert de renfort. On a illustre sur les figures 1 et 5 un chausson d'escalade 10 qui, de maniere connue, est pour l'essentiel compose d'une tige 12, en ['occurrence une tige basse souple, d'une semelle 14 et d'une bande laterale externe de protection 16 qui suit, au moins dans la partie avant du chausson, le bord inferieur de la tige 12. Certains types de chaussons d'escalade vent appeles - Figure 1 is a schematic perspective view of a liner provided with a reinforcement insert in accordance with the teachings of the invention; - Figure 2 illustrates, in plan, a first exemplary embodiment of a reinforcement insert, - Figure 3 is a view similar to that of Figure 2 illustrating an insert provided with a central orifice; - Figure 4 illustrates an insert which is further provided with an integrated rear buttress; Figure 5 is a partial cross-sectional view of the boot of Figure 1; - Figures 6 and 7 illustrate in plan two other alternative embodiments of a reinforcing insert. FIGS. 1 and 5 illustrate a climbing shoe 10 which, in known manner, is essentially composed of a rod 12, in this case a flexible lower rod, a sole 14 and an external lateral protective strip 16 which follows, at least in the front part of the boot, the lower edge of the upper 12. Certain types of climbing shoes are called
ballerinas, et ['invention s'applique aussi a ce type de chaussons. ballerinas, and the invention also applies to this type of booties.
La tige 12 est une tige souple, destinee a etre tres ajustee au pied, et elle comporte par exemple un systeme de lacage 18 pour faciliter ['entree du pied dans le chausson 10 et le serrage du chausson sur le pied. La tige 12 est ici une tige basse, qui ne remonte pas au-dessus de la cheville, mais on pourrait mettre en aeuvre ['invention dans le cadre d'un chausson a tige haute. La tige peut etre realisee en tous types de materiaux couples, notamment en cuir ou en tissue. Wile peut aussi etre realisee en un materiau tisse tridimensionnel qui favorisera ['evacuation de la transpiration. La semelle 14 comporte tout d'abord une semelle premiere 20 qui est par exemple assemblee a la tige selon la technique strobe!. Comme on peut le voir sur la figure 5, la semelle premiere 20 est ainsi reliee bord a bord par une couture 22 avec le bord inferieur de la tige 12. Tres souvent, pour un chausson d'escalade, cette semelle premiere 20 vient 1 0 directement au contact du pied de l'utilisateur, ceci pour eviter la multiplication des epaisseurs qui peuvent nuire a la sensibilite de la perception du terrain par le grimpeur. Dans un chausson The rod 12 is a flexible rod, intended to be very adjusted to the foot, and it comprises for example a lacing system 18 to facilitate ['entry of the foot into the boot 10 and tightening the boot on the foot. The rod 12 is here a low rod, which does not rise above the ankle, but one could implement the invention in the context of a slipper with a high rod. The upper can be made of all types of paired materials, in particular leather or fabric. Wile can also be made of a three-dimensional woven material which will promote the evacuation of perspiration. The sole 14 firstly comprises a first sole 20 which is for example assembled to the upper according to the strobe technique !. As can be seen in Figure 5, the first sole 20 is thus connected edge to edge by a seam 22 with the lower edge of the rod 12. Very often, for a climbing shoe, this first sole 20 comes 1 0 directly in contact with the foot of the user, this to avoid the multiplication of thicknesses which can harm the sensitivity of the perception of the terrain by the climber. In a slipper
traditionnel, cette semelle premiere 20 est directement recouverte par une semelle externe 24. traditional, this first sole 20 is directly covered by an external sole 24.
La semelle externe est realisee en un materiau a kres fort pourvoir adherent et presentant une b onne souple s se, par exempl e un materi au a base de caoutchouc. C ette semel le externe 2 4 presente generalement une epaisseur de l'ordre de 4 mm, au moins dans la partie avant de la The outer sole is made of a material with strong kres to provide adherent and having a flexible b on s se, for example a material based on rubber. This outer sole 2 4 generally has a thickness of the order of 4 mm, at least in the front part of the
semelle 14. La semelle 14 traditionnelle est done une semelle qui est essentiellement souple. sole 14. The traditional sole 14 is therefore a sole which is essentially flexible.
En effet, la nature des materiaux employee, et leur faible epaisseur, font que la semelle n'a que peu de resistance a la deformation face aux efforts qui lui vent imposes. Dans un chausson traditionnel, ce vent done les muscles du pied de l'utilisateur qui encaissent quasi 2 0 integralement les efforts dus aux appuis. Dans les chaussons traditionnels, il arrive que lton trouve, enke la semelle externe et la semelle premiere, des elements de repartition de pression situes soit au centre de la partie avant, soir sur un bord du chausson. Toutefois, ces elements de repartition, localises, presentent des caracteristiques mecaniques tres faibles ayant pour role essentiel de repartir la surpression due par exemple a un appui sur une asperite. Ces elements de repartition de pression ne peuvent, du fait de leurs faibles caracteristiques mecaniques, In fact, the nature of the materials used, and their small thickness, mean that the sole has little resistance to deformation in the face of the forces imposed on it. In a traditional slipper, this wind makes the muscles of the foot of the user which almost fully absorb the forces due to the supports. In traditional slippers, it may happen that, along with the outer sole and the sole, pressure distribution elements located either in the center of the front part, evening on an edge of the liner. However, these localized distribution elements have very weak mechanical characteristics, the essential role of which is to distribute the overpressure due for example to pressing on an asperity. These pressure distribution elements cannot, because of their poor mechanical characteristics,
conferer a la semelle une reelle rigidite globale. give the sole a real overall stiffness.
Au conkaire, le chausson 10 selon ['invention comporte un insert de renfort 26 de maniere In the conkaire, the liner 10 according to the invention comprises a reinforcement insert 26 so
a ma^triser au mieux les deformations de la semelle lors de la mise en appui. to better control the deformations of the sole during the bearing.
Selon un premier mode de realisation de ['invention illustre a la figure 2, ['insert 26 se presente sous la forme d'un element de plaque plan qui presente un contour sensiblement According to a first embodiment of the invention illustrated in FIG. 2, the insert 26 is in the form of a planar plate element which has a substantially contour
identique a celui de la semelle premiere 20, au moins dans la partie avant de la semelle 14. identical to that of the first sole 20, at least in the front part of the sole 14.
Dans les exemples de realisation illustres, le renfort 26 s'etend sur toute la longueur de la semelle, c'est-a-dire jusqu'a une zone de talon de la semelle. Cette configuration est In the illustrated exemplary embodiments, the reinforcement 26 extends over the entire length of the sole, that is to say up to a heel area of the sole. This configuration is
particulierement performante car elle permet de repartir au mieux les contraintes de torsion. particularly efficient because it makes it possible to distribute torsional stresses as well as possible.
Cependant, on peut aussi envisager de realiser ['invention avec un insert qui ne s'etend que However, it is also possible to envisage carrying out the invention with an insert which only extends
sur la partie avant de la semelle, a condition d'en suivre le contour. on the front part of the sole, provided you follow the outline.
Dans la partie arriere de la semelle 14, le contour de ['insert 26 illustre a la figure 2 peut presenter un contour different de celui de la semelle premiere 20, par exemple en presentant In the rear part of the sole 14, the outline of the insert 26 illustrated in FIG. 2 may have a different outline from that of the first sole 20, for example by presenting
une largeur moindre.less width.
Cet insert 26 peut etre realise en differents types de materiaux, a condition qu'ils presentent une rigidite suffisante, c'est-a-dire superieure a celle du materiau de la semelle adherente. Le materiau formant ['insert aura de preference un module d'elasticite (module de Young) superieur a 1 GPa. L'insert pourra ainsi etre realise a ['aide d'une matiere plastique injectee telle que du polyethylene ou du polyurethane rigide. Pour augmenter leurs caracteristiques This insert 26 can be made of different types of material, provided that they have sufficient rigidity, that is to say greater than that of the material of the adherent sole. The material forming the insert will preferably have a modulus of elasticity (Young's modulus) greater than 1 GPa. The insert can thus be produced using an injected plastic material such as polyethylene or rigid polyurethane. To increase their characteristics

L' insert pourra aussi etre realise par exemple par moulage par compression en utilisant une The insert can also be produced for example by compression molding using a

Cependant, le meilleur compromis poids/rigidite sera obtenu en utilisant des materiaux composites a hautes performances tels que des nappes de fibres (de preferences tissees) However, the best compromise between weight and stiffness will be obtained by using high performance composite materials such as plies of fibers (of woven preferences).

Les nappes de fibres seront de preference des tissue de verre ou de carbone. Differents types de tissage et d'orientations de fibres vent envisageables. De meme le grammage des tissue utilises pourra etre adapte aux performances que l'on souhaite obtenir. Ces materiaux composites a hautes performances (ifs presentent un module d'elasticite de l'ordre de 15 a 120 Gpa) seront plus chers que les materiaux cites precedemment, mais ils permettront d'obtenir The fiber layers will preferably be glass or carbon fabric. Different types of weaving and wind fiber orientations possible. Similarly, the grammage of the fabrics used can be adapted to the performance that one wishes to obtain. These high performance composite materials (ifs have an elastic modulus of the order of 15 to 120 Gpa) will be more expensive than the materials mentioned above, but they will make it possible to obtain
un insert plus leger, a caracteristiques mecaniques equivalentes. a lighter insert, with equivalent mechanical characteristics.
Par sa geometric, et par la rigidite intrinseque des materiaux qui le composent, ['insert 26 permet d' augmenter de maniere tres importante la tenue du chausson lorsque le grimpeur prend appui sur une surface uniquement par les carres 34 du chausson, ctest-a-dire par les bords lateraux de la partie avant de la semelle. En effet, grace au fait que ['insert de renfort 26 se prolonge lateralement jusqu'aux bords de la semelle 14, les efforts d'appui imposes aux carres seront directement repris par ['insert. Ces efforts, qui imposent a la semelle des contraintes de torsion, vent transmis jusque vers l' arriere de la semelle, c' est vers la partie du 2 5 pied qui transmet les efforts d'appui vers la jambe du grimpeur. Contrairement a un element de repartition de pression localise, on obtient une bien meilleure tenue en deformation de la By its geometric, and by the intrinsic rigidity of the materials which compose it, [insert 26 makes it possible to increase in a very important way the holding of the boot when the climber is supported on a surface only by the edges 34 of the boot, that is to say - say by the lateral edges of the front part of the sole. Indeed, thanks to the fact that the reinforcing insert 26 extends laterally to the edges of the sole 14, the support forces imposed on the edges will be directly taken up by the insert. These forces, which impose torsional stresses on the sole, wind transmitted as far as the rear of the sole, it is towards the part of the foot which transmits the bearing forces towards the climber's leg. Unlike a localized pressure distribution element, a much better deformation resistance of the
semelle, et on soulage mieux les efforts a fournir par les muscles du pied. sole, and it relieves better the efforts to be provided by the muscles of the foot.
De plus, le fait que ['insert s'etend jusqu'a l'endroit precis de l'appui, c'est-a-dire au niveau des carres, permet a la semelle externe de mieux remplir son role d' adherence. En 3 0 effet, le materiau de cette semelle externe est obligatoirement relativement deformable. Aussi, sous la contrainte de l'appui, le materiau aurait tendance, sans la presence de ['insert, a se deformer exagerement, au point de nuire a ['adherence de l'appui. Au contraire, la carre etant renforcee par ['insert selon ['invention, la deformation du materiau de la semelle externe au niveau de l'appui se trouve limitee et le materiau peut remplir au mieux sa fonction d'adherence. Le meme avantage se retrouve bien entendu en rapport au travail d'adherence qui est parfois rempli par la bande de protection 16, laquelle est generalement realisee avec le In addition, the fact that the insert extends to the precise location of the support, that is to say at the edges, allows the outer sole to better fulfill its role of grip. In fact, the material of this outer sole is necessarily relatively deformable. Also, under the constraint of the support, the material would tend, without the presence of the insert, to deform exaggeratedly, to the point of damaging the adhesion of the support. On the contrary, the edge being reinforced by the insert according to the invention, the deformation of the material of the outer sole at the level of the support is limited and the material can best fulfill its adhesion function. The same advantage is of course found in relation to the adhesion work which is sometimes completed by the protective strip 16, which is generally carried out with the
meme materiau que celui de la semelle externe 24 ou avec un materiau similaire. same material as that of the outer sole 24 or with a similar material.
Sur la figure 3, on a illustre une variante de realisation particulierement interessante de ['invention. En effet, on peut voir que ce second mode de realisation d'un insert de renfort 26 differe du premier par la presence d'un orifice central 28, qui tel qu'illustre, s'etend sur la partie avant de la semelle 14 mais aussi sur une bonne part de la partie arriere de celle-ci. Par la presence de cet orifice 28, ['insert 26 se presente, au moins dans la partie avant de la semelle, comme un cadre peripherique de largeur sensiblement constante qui suit presque exactement le contour externe de la semelle mais qui est evide au centre. La largeur du cadre In Figure 3, there is illustrated a particularly interesting alternative embodiment of the invention. Indeed, it can be seen that this second embodiment of a reinforcing insert 26 differs from the first by the presence of a central orifice 28, which as illustrated, extends over the front part of the sole 14 but also on a good part of the back part of it. By the presence of this orifice 28, the insert 26 presents itself, at least in the front part of the sole, as a peripheral frame of substantially constant width which almost exactly follows the external contour of the sole but which is hollow in the center. The width of the frame
peripherique est par exemple comprise entre 4 et 20 mm. peripheral is for example between 4 and 20 mm.
La presence de ltorifice central 28 presente l'avantage de renforcer la tenue de la semelle au niveau des bords lateraux, sans pour autant degrader de maniere trop importante la capacite de la semelle a transmettre des informations sensorielles au pied quant aux micro-reliefs de la 1 0 surface sur laquelle le pied prend appui. En effet, dans la partie centrale de la semelle, celle qui correspond a ltorifice central 28, la semelle 14 possede la meme capacite de deformation qu'une semelle kaditionnelle, au moins selon une direction perpendiculaire au plan de la semelle. Ainsi, par cette partie centrale, le grimpeur peut sentir les asperites du terrain sur lequel il prend appui, sans que ces asperites ne soient filtrees par la presence d'un insert couvrant la totalite de ['avant-pied. Avec cette configuration, ['insert 26 conserve une bonne partie de ses capacites a ameliorer la tenue en torsion de la semelle. On note d'ailleurs que ltorifice central 28 pourrait ne s'etendre que sur la partie avant de la semelle, la ou s'effectue la majeure partie de la perception sensorielle, les parties centrales et arriere de ['insert pouvant The presence of the central opening 28 has the advantage of strengthening the grip of the sole at the level of the lateral edges, without however degrading in too great a way the ability of the sole to transmit sensory information to the foot as to the micro-reliefs of the 1 0 surface on which the foot is supported. Indeed, in the central part of the sole, that which corresponds to the central hole 28, the sole 14 has the same deformation capacity as a conventional sole, at least in a direction perpendicular to the plane of the sole. Thus, by this central part, the climber can feel the asperites of the ground on which it is supported, without these asperites being filtered by the presence of an insert covering the whole of the forefoot. With this configuration, the insert 26 retains much of its ability to improve the torsional strength of the sole. It should also be noted that the central opening 28 could extend only over the front part of the sole, where most of the sensory perception takes place, the central and rear parts of the insert being able to
etre pleines pour renforcer l'effet anti-torsion de ['insert. be full to enhance the anti-twist effect of the insert.
Aux figures 6 et 7, on a illustre deux variantes de realisation de ['invention qui visent a conferer une rigidite progressive a [' insert entre le contour lateral, que l' on veut rigide, et la partie centrale correspondent a ['orifice 28. Cet objectif peut etre atteint en prevoyant que ['insert presente des lamelles 34 qui s'etendent selon une direction radiale vers le << centre >> de ['orifice 28, dans le plan de ['insert. Dans l'exemple de la figure 6, ces lamelles 34 vent obtenues simplement en prevoyant, dans le cadre peripherique de ['insert qui entoure ['orifice central 28, des decoupes 36 d'orientation sensiblement radiales qui debouchent dans le bord interne delimitant ['orifice 28. Bien entendu, ces decoupes 36 ne s'etendent pas jusqu'au bord externe de ['insert. Dans l'exemple de la figure 7, les lamelles 34 vent espacees les une des In FIGS. 6 and 7, two alternative embodiments of the invention have been illustrated which aim to impart progressive rigidity to the insert between the lateral contour, which one wishes to be rigid, and the central part correspond to the orifice 28 This objective can be achieved by providing that the insert has lamellae 34 which extend in a radial direction towards the "center" of the orifice 28, in the plane of the insert. In the example of FIG. 6, these strips 34 are obtained simply by providing, in the peripheral frame of the 'insert which surrounds the central orifice 28, cutouts 36 of substantially radial orientation which open out into the internal edge delimiting [ orifice 28. Of course, these cutouts 36 do not extend to the outer edge of the insert. In the example of FIG. 7, the slats 34 wind the spaces one of the
autres par des interstices 38, et elles stetendent vers le centre sur une plus grande longueur. others by interstices 38, and they extend towards the center over a greater length.
Les lamelles 34 presentent une forme sensiblement trapezodale, c'est-adire que leur largeur decroit et est minimale a leur extremite radiale interne libre. Bien entendu, les lamelles pourraient presenter encore d'autres formes, par exemple une forme triangulaire. Dans tous les cas, les lamelles 34 travaillent en flexion selon une direction perpendiculaire au plan de la semelle, leur extremite radiale externe etant << ancree >> sur le cadre peripherique de ['insert 26 et leur extremite radiale interne suivant les deformations de la semelle au centre de ['orifice 28. On obtient ainsi une rigidite decroissante radialement de l' exterieur vers l' interieur de The slats 34 have a substantially trapezoidal shape, that is to say that their width decreases and is minimal at their free internal radial end. Of course, the lamellae could have other shapes, for example a triangular shape. In all cases, the lamellae 34 work in flexion in a direction perpendicular to the plane of the sole, their outer radial end being "anchored" on the peripheral frame of the insert 26 and their inner radial end according to the deformations of the sole in the center of the orifice 28. This gives a decreasing stiffness radially from the outside to the inside of
['orifice central 28.['central opening 28.
On pourrait aussi prevoir que la rigidite differentielle selon la direction radiale soit formee par une variation d'epaisseur de ['insert selon cette direction. Dans tous les cas, une telle conception evite que la rigidite de la semelle varie brutalement au niveau du bord de ['orifice It could also be provided that the differential stiffness in the radial direction is formed by a variation in thickness of the insert in this direction. In all cases, such a design prevents the rigidity of the sole from suddenly varying at the edge of the orifice.
central 28.central 28.
A la figure 4, on a illustre un insert de renfort similaire a celui de la figure 3 mais dont la partie arriere se prolonge par un contrefort 30. Le contrefort 30 remonte verticalement, selon une direction sensiblement perpendiculaire au plan de la semelle, pour venir couvrir l'arriere du talon de l'utilisateur. En associant le contrefort 30 a ['insert, on renforce considerablement la capacite du chausson a transmettre les efforts de torsion du pied vers la jambe. Dans l'exemple illustre, le contrefort 30 presente une faible largeur au niveau de sa partie basse de liaison avec le reste de ['insert 26, et il s'evase vers le haut. De plus, on peut voir que le contrefort est evide en son centre 40 pour limiter son contact avec le tendon d'Achille qui est une zone particulierement sensible du pied. L'insert 26 avec son contrefort 30 forment une piece tridimensionnelle. Pour des raisons de facilite de construction, ils pourront etre realises en deux elements (la partie semelle de ['insert etant alors sensiblement plane) assembles l'un a In FIG. 4, a reinforcing insert is illustrated similar to that of FIG. 3 but the rear part of which is extended by a buttress 30. The buttress 30 rises vertically, in a direction substantially perpendicular to the plane of the sole, to come cover the back of the user's heel. By associating the buttress 30 with the insert, the capacity of the liner is considerably strengthened to transmit torsional forces from the foot to the leg. In the example illustrated, the buttress 30 has a small width at its lower connecting part with the rest of the insert 26, and it widens upwards. In addition, it can be seen that the buttress is hollow at its center 40 to limit its contact with the Achilles tendon which is a particularly sensitive area of the foot. The insert 26 with its buttress 30 form a three-dimensional piece. For reasons of ease of construction, they may be produced in two elements (the sole part of the insert then being substantially planar) assembled one at a time.
l'autre, par exemple par collage.the other, for example by gluing.
Le contrefort 30 pourra etre concu de maniere a exercer, par effet ressort, un effort de pression sur la partie arriere du talon. Cet effort de pression participera a un meilleur maintien du chausson sur le pied. En effet, un grimpeur est rarement en appui sur le talon et, au cours de certains gestes, le talon de la chaussure a tendance a se decoller du pied. Le contrefort, en ayant un effet ressort, permettra de tonjours maintenir le talon du chausson an contact du pied, The buttress 30 may be designed so as to exert, by spring effect, a pressure force on the rear part of the heel. This pressure effort will contribute to better support of the liner on the foot. Indeed, a climber is rarely supported on the heel and, during certain gestures, the heel of the shoe tends to come off the foot. The buttress, having a spring effect, will always keep the heel of the bootie in contact with the foot,
2 0 empechant ainsi toute ebauche de dechaussage. 2 0 thus preventing any sketch of heaving.
Dans tous les exemples decrits jusqu'a present, la partie de ['insert correspondent a la semelle est plane. Cependant, on peut prevoir que cette partie de ['insert presente une forme tridimensionnelle adaptee, au moins partiellement, a la forme du pied. Cela sera particulierement facile a obtenir si ['insert est realise par moulage, que ce soit par injection ou par compression. De plus, en donnant un caractere fortement tridimensionnel a la partie arnere de ['insert, on pourra augmenter de maniere tres importante la rigidite de cette partie arriere, done la capacite de la semelle a resister aux contraintes de torsion et a reporter les efforts vers la jambe du grimpeur. On aura au contraire interet a conserver une partie avant de ['insert relativement plane pour conserver une certaine flexibilite dans cette partie de la In all the examples described so far, the part of the insert corresponding to the sole is flat. However, it can be expected that this part of the insert has a three-dimensional shape adapted, at least partially, to the shape of the foot. This will be particularly easy to obtain if the insert is produced by molding, whether by injection or by compression. In addition, by giving a strongly three-dimensional character to the rear part of the insert, it will be possible to very significantly increase the rigidity of this rear part, therefore the capacity of the sole to resist torsional stresses and to transfer the forces to the climber's leg. On the contrary, it will be of interest to keep a front part of the relatively flat insert to keep a certain flexibility in this part of the
semelle.sole.
A la figure S. on a illustre un mode d'assemblage particulierement avantageux du chausson In Figure S. there is illustrated a particularly advantageous method of assembling the liner
muni d'un insert de renfort selon ['invention. provided with a reinforcement insert according to the invention.
On peut ainsi voir que ['insert est plaque directement contre la face inferieure de la semelle premiere 20. On volt par ailleurs que la bande laterale de protection 16, qui stetend pour l'essentiel le long du bord inferieur de la tige 12, comporte une partie rabattue 32 qui vient recouvrir, par en dessous, au moins partiellement ['insert 26. La semelle externe 24 est ensuite rapportee par en dessous. Avec cette construction, le bord de ['insert est parfaitement cache It can thus be seen that the insert is plate directly against the lower face of the first sole 20. It is also known that the lateral protective strip 16, which essentially stretches along the lower edge of the rod 12, comprises a folded portion 32 which covers, from below, at least partially ['insert 26. The outer sole 24 is then attached from below. With this construction, the edge of the insert is perfectly hidden
par la bande de protection 16.by the protective strip 16.
L' insert selon [' invention permet done d' avoir un chausson dans loquel la transmission des efforts de torsion se fait par un travail homogene de ['ensemble de la semelle, sans rigidifier cette derriere outre mesure dans le sens de sa flexion, ce qui permet d'apporter de la precision dans le contrGle des appuis. Dans les versions munies d'un orifice central, l'effet de cadre de ['insert assure une tres bonne tenue des carres du chausson, tout en conservant au grimpeur une tres bonne capacite de ressentir la nature et les asperites de la surface sur laquelle il prend appu'. The insert according to the invention therefore makes it possible to have a liner in which the transmission of the torsional forces is done by a homogeneous work of the whole of the sole, without stiffening the latter excessively in the direction of its flexion, which allows to bring precision in the control of the supports. In the versions provided with a central orifice, the frame effect of the insert ensures very good hold of the edges of the liner, while retaining to the climber a very good ability to feel the nature and the asperites of the surface on which he takes support.
