Abstract

The ejectable fin has a root (3) shaped to fit into a recess in the board and separate from it in the event of a shock to prevent damage. The root of the fin has projections at both ends, one engaging with a notch (5) in the board recess, and the other engaging with an elastic pusher (4) contained in the opposite end of the recess. The fin is attached by a flexible line (6) to the inside of the recess so that it does not get lost on separation. When the fin strikes a solid object it is pushed back against the elastic pusher (4), becoming detached from the notch and is then ejected from the board recess. USE/ADVANTAGE - Easier fitting and less damage on collision. For a surfboard or sailboard.

Description

La présente invention concerne un dispositif à l'usage de la planche à voile et des planches de surf relative à l'emplanture d'aileron arrière éjectable en cas de choc. The present invention relates to a device for the use of windsurfing and surfboards relating to the root of the rear wing which can be ejected in the event of an impact.

La fixation d'aileron arrière est traditionnellement effectuée à l'aide de vis mécanique bloquant l'aileron dans le logement de l'emplanture. Avec ce mode de fixation l'aileron arrière avec son emplanture se brisent ou s'arrachent de la planche en cas de choc. The fixing of the rear wing is traditionally carried out using mechanical screws blocking the rear wing in the seat of the root. With this method of attachment, the rear spoiler with its root will break or tear off the board in the event of an impact.

Ce dispositif selon l'invention permet de remédier à cet inconvénient. I1 comporte en effet un boîtier (1) présentant un orifice (2) par laquelle est introduit la partie supérieure de l'aileron (3).  This device according to the invention overcomes this drawback. I1 in fact comprises a housing (1) having an orifice (2) through which the upper part of the fin (3) is introduced.

Selon une forme de réalisation préférentielle ( Fig. t) ce dispositif se caractérise par un crant-d'arrêt (5) muni à son extrémité d'un poussoir élastique (4) permettant le maintient de l'aileron (3) dans sa cavité (2).  According to a preferred embodiment (Fig. T) this device is characterized by a catch-stop (5) provided at its end with an elastic plunger (4) allowing the retention of the fin (3) in its cavity (2).

Ce dispositif se caractérise par le fait qu'il a l'avantage lors d'un choc éventuel de se déclancher permettant à l'aileron (3) de sortir de sa cavité (2) sans endommager l'emplanture (f) ou le flotteur. This device is characterized by the fact that it has the advantage, in the event of a possible impact, of being released allowing the fin (3) to exit from its cavity (2) without damaging the root (f) or the float. .

Ce dispositif se caractérise par le fait que lorsque l'aileron (3) est éjecté de son logement (t) à la suite d'un choc l'aileron (3) est retenu par un bout (6) à l'emplanture (1) évitant sa perte. This device is characterized by the fact that when the fin (3) is ejected from its housing (t) following an impact, the fin (3) is retained by an end (6) at the root (1 ) avoiding its loss.

Ce dispositif d'emplanture se caractérise par le fait qu'il peut recevoir tous types d'aileron ayant la même embase (3). This rooting device is characterized by the fact that it can receive all types of fin having the same base (3).

Ce dispositif se caractérisant par sa nouvelle forme
Fig. 1 et Fig. 2 peut-être réalisé soit individuellement en moulage injecté ou moulage manuel soit incorporé directement au flotteur lors de sa fabrication.This device is characterized by its new shape
Fig. 1 and Fig. 2 can be carried out either individually in injected molding or manual molding or incorporated directly into the float during its manufacture.

Ce dispositif se caractérise par le fait outil peut-8tre fabriqué de toutes les dimensions et dans tous les matériaux.  This device is characterized by the fact that the tool can be made of all sizes and in all materials.
