Description
DESCRIPTIONDESCRIPTION
L'invention concerne un dispositif de cheville de fixation destiné à fixer des éléments plus ou moins rigides sur des panneaux de mousse plus ou moins souple en usage dans le domaine des airs de jeux aquatiques.The invention relates to a fixing peg device intended to fix more or less rigid elements on more or less flexible foam panels in use in the field of water play tunes.
Etat des connaissances :State of knowledge:
Les dispositifs de cheville destinés à être fixés dans des matériaux en mousse (dit aussi chevilles pour ancrage dans le polystyrène : marques « Tox », « Fischer », « Rawl fixings » ...) sont plus particulièrement connus dans le secteur du bâtiment, notamment pour assurer la fixation d'objets sur la vêture de bâtiments ayant reçu un isolant polystyrène. Ce type de dispositif subit un effort mécanique statique avec une limite de charge recommandée ne dépassant pas 10kg. Cette technologie reçoit uniquement des vis de type bois ou aggloméré/bois, qui se caractérisent par un filetage fin et taillant avec un pas de vis de faible dimension, tandis que le diamètre de vis est réduit pour être en capacité de pénétrer le matériau en bois qui présente par ailleurs des qualités de résistances mécaniques plus ou moins importantes selon la densité des essences utilisées. De plus ces chevilles ne reçoivent aucun taraudage dans le logement de la vis, puisque c'est la vis elle-même qui officie le taraudage au moment de la fixation. La caractéristique des vis employées et la conception des chevilles à l'effet de cet emploi indisposent une reprise de charge pour un effort dynamique du fait que le pas de vis de la cheville sur son périmètre n'est pas étudié pour empêcher l'arrachement de charges lourdes ou oscillantes.Anchor devices intended to be fixed in foam materials (also known as anchors for anchoring in polystyrene: brands "Tox", "Fischer", "Rawl fixings" ...) are more particularly known in the building sector, in particular to ensure the fixing of objects on the clothing of buildings having received a polystyrene insulation. This type of device undergoes static mechanical stress with a recommended load limit not exceeding 10kg. This technology only receives wood or chipboard / wood type screws, which are characterized by a fine thread and cutting with a small screw pitch, while the screw diameter is reduced to be able to penetrate the wooden material which also has more or less important mechanical resistance qualities depending on the density of the species used. In addition, these dowels do not receive any tapping in the housing of the screw, since it is the screw itself which officiates the tapping at the time of fixing. The characteristic of the screws used and the design of the ankles to the effect of this use induce a load recovery for a dynamic effort because the pitch of the ankle on its perimeter is not studied to prevent tearing of heavy or oscillating loads.
Dans le domaine des jeux aquatiques, qui font appel à des équipements en matière mousse ou polymère de faible densité (airs de jeux aquatiques notamment), le seul moyen connu actuellement consiste à fixer des éléments en faisant appel à des dispositifs d’écrous et de boulons qui ont pour particularité de pénétrer en totalité les éléments assemblés, si bien que ces dispositifs présentent un risque de choc et de blessure auprès de usagers, que ceux-ci tentent de limiter par des formes et matières particulières aux fins de limiter ces risques.In the field of water games, which use equipment made of low density foam or polymer (water games air in particular), the only means currently known is to fix elements using nuts and fittings. bolts which have the particularity of fully penetrating the assembled elements, so that these devices present a risk of shock and injury to users, which they try to limit by particular shapes and materials in order to limit these risks.
Présentation de l'inventionPresentation of the invention
L'invention concerne un dispositif de cheville de fixation destiné à fixer des éléments plus ou moins rigides sur des panneaux de mousse plus ou moins souple en usage dans le domaine des aires de jeux aquatiques. Le système de cheville se distingue des dispositifs connus en milieu aquatique de type piscine en ce que la fixation n'est pas destinée à pénétrer en totalité les surfaces assemblées, mais est destinée à se fixer dans ces dernières, tout en offrant une résistance aux efforts dynamiques de plus de 30Kg.The invention relates to a fixing peg device intended to fix more or less rigid elements on more or less flexible foam panels in use in the field of aquatic play areas. The ankle system differs from known devices in the aquatic environment of the swimming pool type in that the fixing is not intended to penetrate the entire assembled surfaces, but is intended to be fixed in the latter, while offering resistance to forces. dynamics of more than 30Kg.
Le dispositif de cheville se caractérise par :The ankle device is characterized by:
- Un taraudage (a) contenu dans le logement destiné à recevoir une vis à pas métrique, Un pas de vis (b) positionné sur le périphérique extérieur de la cheville, d'au moins 0,8 centimètres. A cet effet il importe de tenir compte de la caractéristique mécanique faible du support en mousse qui est très vite rendu vétuste par l'action de vissage détériorant ce support. Selon ce principe, plus le pas de vis est faible et plus il contrevient à la préservation de la mousse en périphérie du vissage, en ce que le mouvement du pas de vis en pénétration ne laissant pas assez d'espace suffisant à la mousse pénétrée, la déchire dans son périmètre au-delà de l'espace de la pénétration. C'est pourquoi la dimension du pas de vis d'au moins de 0,8cm est indispensable à la préservation de la mousse pénétrée,- A thread (a) contained in the housing intended to receive a metric thread screw, A thread pitch (b) positioned on the external device of the ankle, of at least 0.8 centimeters. For this purpose it is important to take into account the weak mechanical characteristic of the foam support which is quickly rendered dilapidated by the screwing action deteriorating this support. According to this principle, the weaker the pitch of the screw and the more it contravenes the preservation of the foam at the periphery of the screwing, in that the movement of the pitch of the screw in penetration does not leave enough sufficient space for the penetrated foam, tears it in its perimeter beyond the space of penetration. This is why the dimension of the screw pitch of at least 0.8 cm is essential for the preservation of the penetrated foam,
- Un filetage extérieur (c) sur le périmètre de la cheville, filetage de type triangulaire et désaxé présentant une forme perpendiculaire au corps de la cheville (d) selon le principe que le flanc du filet exposé à la pénétration (e) de la mousse est incliné à un angle supérieur à 90° par rapport au sens de pénétration ; ceci aux fins d'éviter l'arrachement du support en phase de vissage et d'offrir moins d'effort à la pénétration,- An external thread (c) on the perimeter of the dowel, triangular and offset type thread having a shape perpendicular to the body of the dowel (d) according to the principle that the side of the thread exposed to the penetration (e) of the foam is inclined at an angle greater than 90 ° to the direction of penetration; this in order to avoid the tearing of the support during the screwing phase and to offer less effort to penetration,
- Une hauteur de filetage (c) d'au moins un tiers du diamètre du corps la cheville, aux fins d'amplifier les surfaces d'appui entre la cheville et la mousse et ainsi de mieux les solidariser. Si la cheville dispose d'un corps de diamètre 15 mm, la hauteur de filetage devra être de 5mm minimum.- A thread height (c) of at least one third of the diameter of the ankle body, in order to amplify the bearing surfaces between the ankle and the foam and thus better secure them. If the dowel has a 15 mm diameter body, the thread height must be at least 5 mm.
- L'arrête (f) du filet dispose d'un tranchant permettant d'amplifier la pénétration nette du support sans endommager le périmètre immédiat de la pénétration par des phénomènes d'arrachement du support,- The stop (f) of the net has a cutting edge allowing to amplify the net penetration of the support without damaging the immediate perimeter of the penetration by phenomena of tearing of the support,
Une collerette (g) placée sur le dessus de la cheville, le diamètre de cette collerette (g) étant au moins égal au diamètre hors-tout de la cheville en sa partie recevant le filetage (c).A flange (g) placed on top of the dowel, the diameter of this flange (g) being at least equal to the overall diameter of the dowel in its part receiving the thread (c).
La collerette (g) évite que la cheville ne s'enfonce dans la mousse au-delà de sa garde. Ainsi la mousse qui reçoit la cheville est retenue par la collerette, ce qui provoque un phénomène de compression de la mousse au point de contact avec la collerette, point de compression qui renforce la tenue mécanique de la fixation dans la mousse.The collar (g) prevents the ankle from sinking into the foam beyond its guard. Thus the foam which receives the ankle is retained by the flange, which causes a phenomenon of compression of the foam at the point of contact with the flange, a compression point which strengthens the mechanical strength of the fixing in the foam.
