Definitions

• This patent of Utility Model refers to a constructive disposition of adjustment of the removable lateral fins in surfboard that allows multiple tuning options by means of juxtaposition of the fin to the graduate rift in the fitting cup, guaranteeing to the surfers the possibility to adapt the surfboards to their own ability degree in practice of the surf, as well as to the marine conditions, without for so be compelled to use different types of boards.
• the fins while willing material bodies in the part of bass of the surfboards, elaborated with plastic foam (polyurethane) molded and covered by fine layer of polyester resin reinforced with fiber, usually of glass, since approximately the 1950 decade, consubstantiate in an important accessory of the surfboards, in view of the fact that the surfers depend on the positioning adopted to the fins and it disposition in the surfboard to have larger projection and speed or larger stability or larger perform maneuvers. In that way, different fin fitting techniques and positioning have been adopted.

• Figure 2 Lateral view of the outside face of the lateral fitting cup that it is addressed to the inside of the board;
• Figure 3 Lateral view of the outside face of the lateral fitting cup that it is addressed to the outside of the board;
• Figure 4 Frontal outside view of the fitting cup;

• Figure 7 Plan view of lateral fin in the fitting positioned in the graduate tuning rifts to the left or turn aside exterior of the surfboard;
• Figure 8 Plan view of the lateral fin juxtaposed in the fitting cup, allowing observe the fin base in the fitting in the graduate rift at central position;
• Figure 9 Plan view the lateral fin in the fitting positioned in the graduate tuning rifts to the right or turn aside interior of the surfboard;
• Figure 10 Perspective view of the fitting cup
• Figure 11 Plan view of the tail portion of a surfboard, evidencing the positioning of the lateral fins related to the central fin;
• the constructive disposition of adjustment of the removable lateral fins in surfboard is composed by the surfboard fin (2) with specific base (5) set, juxtaposed to the fitting cup (1), endowed with opening or incision (3), that possesses in tip front graduate rifts (4), which will address the fin to the user's need.
• the fitting cup (1) is built-in inside the surfboard tail portion (16), and it is produced in plastic or similar material, of equal or superior lightness and resistance. It is characterized by possessing middle opening or incision (3) in which in it back tip there is a semi-circumference (5), from where fit in the posterior tip (13) of the fin's (2) base (6), that it is rounded; and in the front tip of the middle opening or incision (3) is endowed of graduate rifts (4) that allow, preferentially, three degrees of direction of the fin (2) fastened by the front tip (12) of the fin's (2) base (6), that it is triangular sharp, influencing in the performance of the surfboard.
• the fin (2) is juxtaposed to the fitting cup (1) by the fixation of the edge (7), that blunts from the lateral of the fin's (2) base (6), to the void accommodation space (8), through a flat head screw (9) that passes in the duct (10) existent in the lateral edge (7) and attaches on the spiraled hole (11), horizontality to the center fitting cup (1), close to the inside lateral face of the opening or incision (3).
• this saliency aids in the fitting of the fin's (2) base (6), accommodating the reentrance (14) of the fin's (2) base (6), a little superiors dimensions to that, vertically disposed in the inferior extremity of the lateral edge (7).
• the exhibit attributes allow to catalog the constructive disposition of adjustment of the removable lateral fins in surfboard as a totally efficient and practical way for several types of users application that needs a accurate, security and versatile conditional of multiple surfboard lateral fins' (2) tuning accomplishing (attack angles), because it allows the manual packaging of lateral fin (2) to the fitting cup (1) in the surfboard by the surfer before the practice of the sport.
