Abstract

Artificial structure elements for training sportsmen in climbing: removable holds. Arrangements providing these holds with a structure such that the part subjected to a traction force resists this force particularly well, for example: glass laminate fabric 3 on the back of the hold 2.

Description

La présente invention concerne des éléments de structures artificielles pour l'entraînement des sportifs à l'escalade rocheuse. The present invention relates to elements of artificial structures for training athletes in rock climbing.

Traditionnellement1 les stuctures artificielles d'escalade, ou murs d'escalade, sont construits suivant plusieurs techni -ques.Les plus courantes consistent à recouvrir un mur existant par du béton projeté sur un support gillagé, de modeler ce béton et d'y insérer des pierres choisies pour leurs formes et leurs possibilités de préhension. Traditionally1 artificial climbing structures, or climbing walls, are built using several techniques, the most common of which are to cover an existing wall with concrete sprayed on a gillage support, to mold this concrete and to insert stones chosen for their shapes and their grip possibilities.

Il y a une dizaine d'années sont apparue des murs en béton sur lesquels-sont fixées des prises artificielles par l'intermédiaire de vis assujetties dans le mur au moyen de chevilles à expansion.Ces prises sont constituées par des pièces de bois taillées de différentes façons, le plus souvent ces prises sont grossièrement parallélépipèdiques avec des pans plus ou moins inclinés pour obtenir des préhensions plus ou moins difficiles. Concrete walls appeared about ten years ago, on which artificial sockets are fixed by means of screws fixed in the wall by means of expansion plugs. These sockets are made of pieces of wood cut from different ways, most often these grips are roughly parallelepipedic with sides more or less inclined to obtain more or less difficult grips.

Plus récement sont apparues des prises en béton de résine, technique offrant une grande souplesse d'utilisation et une possibilité de production/moulage en série. More recently, resin concrete plugs have appeared, a technique offering great flexibility of use and the possibility of mass production / molding.

Ces prises, les plus performantes actuellement sur le marché, tant sur le plan du toucher que sur le plan de l'adhé- -rence, présentent un inconvénient majeur: elles ont tendance à se casser dès que le support n'est pas parfaitement plan. These sockets, the most efficient currently on the market, both in terms of touch and adhesion, have a major drawback: they tend to break as soon as the support is not perfectly flat .

Les bétonsde résine employés courament ont une mauvaise résistance à la traction.  The resin concretes commonly used have poor tensile strength.

Ces prises travaillent toujours comme des poutres en flexion simple, la fibre tendue étant contre le mur d'appui, et l'effort de flexion étant imprimé par la vis de fixation. These sockets always work like beams in simple bending, the stretched fiber being against the bearing wall, and the bending force being printed by the fixing screw.

L'idée est donc d'utiliser un matériau plus performant en trction dans les parties tendues et de garder le béton de résine aux autres endroits où sa résistance à la compression est suffisante. The idea is therefore to use a more efficient material in trction in the stretched parts and to keep the resin concrete in the other places where its resistance to compression is sufficient.

Par exemple et sans limitation, ce matériau peut être : des fibres de verre1 de carbone de Kevlar ou une plaque d'un matériau ayant un module d'elasticité supérieur à celui du béton de résine employé, plaque métallique ou synthétique. For example and without limitation, this material can be: glass fibers1 of Kevlar carbon or a plate of a material having a modulus of elasticity greater than that of the resin concrete employed, metallic or synthetic plate.

Suivant une disposition préférentielle non exclusive : la partie tendue sera constituée d'un tissu de fibres de verre stratifié sur le dos de la prise. According to a non-exclusive preferential arrangement: the stretched part will consist of a fiberglass fabric laminated on the back of the socket.

Par ailleurs, et suivant une disposition préférentielle ces prises, si elles sont amenées à être fixées à l'aide de vis, ont la face d'appui 5 figure 2 légèrement concave de sote que le contact se fasse d'abord sur les bords extèrieurs le plus loin possible du point de fixation et que, par ltélas- -ticité du matériau, le contact s'étende de l'extèrieur vers l'interieur par resserrement de la vis. Cette disposition permet d'avoir : un couple de frottement maximum et une sur -face de frottement ce qui évite à cette prise de tourner lors de son utilisation. Furthermore, and according to a preferential arrangement, these sockets, if they are to be fixed using screws, have the bearing face 5 in FIG. 2 slightly concave so that the contact is made first on the outer edges as far as possible from the fixing point and that, by the elasticity of the material, the contact extends from the exterior towards the interior by tightening the screw. This arrangement makes it possible to have: a maximum friction torque and a friction surface which prevents this plug from turning during its use.

La concavité est fonction du module d'élasticité du matériau : plus celui-ci est faible, plus la concavité a besoin d'être importante; pour un matériau infiniment rigide cette face pourrait être plane. Cette disposition assure une répartition de pression à peu près uniforme. The concavity is a function of the elastic modulus of the material: the lower the latter, the greater the concavity needs to be; for an infinitely rigid material this face could be plane. This arrangement ensures an almost uniform pressure distribution.

Il est évident qu'une prise peut présenter plusieurs structures caractéristiques d'un type de roche ou même de plusieurs types de roches differentes, cette disposition est particulièrement avantageuse pour les prises fixées par une vis centrale, car en faisant tourner ces prises sur ellesmêmes on peut alors faire évoluer les passages du mur d'esca -lade, ajuster les difficultés aux utiltsateurs et gagner ainsi en diversité donc en intérêt. It is obvious that a socket can have several structures characteristic of a type of rock or even of several different types of rock, this arrangement is particularly advantageous for the holds fixed by a central screw, because by rotating these holds on themselves we can then make the passages of the climbing wall evolve, adjust the difficulties for the users and thus gain in diversity therefore in interest.

L'innovation sera mieux comprise à la lumière des dessins sur lesquels --- la figure 1 représente une prise en béton de résine suun support irregulier avec
1. la vis de fixation
2. la prise d'esca lade
3. le renfcrt en stratifié de verre par exemple
4. le support (en béton pra exemple) --- la figure 2 représente une prise avec un dos légèrement concave pour maximiser le couple de frottement.
The innovation will be better understood in the light of the drawings in which --- FIG. 1 represents a socket in resin concrete on an irregular support with
1. the fixing screw
2. the escalation
3. the glass laminate for example
4. the support (in concrete pra example) --- figure 2 represents a catch with a slightly concave back to maximize the couple of friction.
