Title (EN) VARIABLE ANGLE FIN
(FR) AILERON A ANGLE VARIABLE
Abstract:
(EN) A fin (1), used on water craft (25) such as surfboards, giving an adjustable angle (A) to the transverse axis of the water craft (25). The fin (1) is frictionally or mechanically locked in a selected one of a number of possible angular positions. One form includes a box (22), placed in the water craft (25), having a circular sectioned groove (9) which closely houses a cylindrical intermediate section (21), the fin closely sits in a slot within the section (21) and the assembly is clamped tight by screws (19) which force the root (2) of the fin (1) against the bottom of the groove (9).
(FR) Un aileron (1), utilisé dans une petite embarcation (25) telle une planche de surf, fournit un angle réglable A à l'axe transversal de l'embarcation (25). L'aileron (1) est verrouillé par friction ou mécaniquement dans une position choisie à partir d'un certain nombre de positions angulaires possibles. Un modèle comprend un boîtier (22) placé dans l'embarcation (25) et doté d'une rainure à section circulaire (9) qui loge étroitement une partie intermédiaire cylindrique (21). L'aileron se fixe étroitement dans une fente ménagée dans la partie (21) et l'ensemble est fortement fixé par des vis (19) qui reserrent la base (2) de l'aileron (1) contre le fond de la rainure (9).
