<p>Mast heel for a windsurfing board consisting in a support (1) fixed on the windsurfing board in a swivel joint connected to the support; a multidirectional mobility between both parts is thus obtained. These parts are provided with a half-shell or a ring shaped shell (8), and with a sphere acting as a bearing or with a ring (4) in the shape of a pudding (5), these elements being engaged with one another. The support (1) and the swivel joint (6) are held together by a rod (12), which on the one hand, facilitates the separation of the swivelling connection by means of the resilient elongation of the rod (12) and on the other hand, makes it possible, after separation, to reassemble the elements of the swivelling connection. In order to facilitate the displacement of the mast on the windsurfing board, the support (1) is connected to a curser which is longitudinally displaceable on the board or the support and the curser are integral. </p> |
