Fin Fixing System

Abstract

This invention is directed toward a fin box capable of accepting either a Futures or an FCS fin without the need for any additional products being added to either the fins or the fin box. The box has an internally-adjustable wedge that can force the bottom of a fin into an indent, thereby giving it a cant or angle. The box also has channels for both FCS and Futures fins, such that a user can easily exchange either brand of fin without adding or subtracting items from the fins or fin boxes.

DETAILED DESCRIPTION OF THE FIGURES

[0076] Many aspects of the invention can be better understood with references made to the drawings below. The components in the drawings are not necessarily drawn to scale. Instead, emphasis is placed upon clearly illustrating the components of the present invention. Moreover, like reference numerals designate corresponding parts through the several views in the drawings. Before explaining at least one embodiment of the invention, it is to be understood that the embodiments of the invention are not limited in their application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The embodiments of the invention are capable of being practiced and carried out in various ways. In addition, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0077] FIG. 1 is a lateral cross section of a fin fixing system according to the invention. The general concept behind this fin box is that through the movement of basically five screws and a wedge, a single fin box can handle fins from both FCS and Futures. There are no inserts needed or anything else to adhere to a fin or insert into the fin box the box; the fin box comes with everything a surfer needs to use either an FCS or a Futures fin. The fin box, 1 shows the parallel channel 3 created by the encroachment of the wedge 2 and the indent 5 for the acceptance of an FCS fin base. The wedge 2 can be adjusted by the wedge adjustment screw 6 which lies in a wedge screw access 12. On the other side of the fin box 1 is a grub screw hole 11 in which a grub screw 7 can be placed, which can be used to exert pressure on the other side of the fin thus retaining the fin in place.

[0078] FIG. 2 is a lateral cross section of the fin fixing system according to the invention. In this figure, the wedge 2 has been retracted from an active position through the screwing down of the wedge adjustment screw 6 which rests in the wedge screw access 12. Due to the retraction of the wedge 2 the parallel channel 4 now becomes available for the acceptance of a Futures fin base as shown in FIG. 6.

[0079] FIG. 3 is a lateral cross section of the fin fixing system shown in FIG. 1. With an FCS fin 8 and Base 9 inserted into the fin box 1. The FCS fin base 9 resides in the parallel channel 3 created by the indent 5 and the wedge 2. The grub screw 7 is exerting pressure on the FCS fin base 9 to keep it in the channel 3. Wedge 2 has been activated by the wedge adjustment screw 6 and in cooperation with the indent 5 the channel 3 creates the required cant angle for FCS fin 8. Thereby creating the required cant angle for the FCS fin 8

[0080] FIG. 4 is a side and front view representation of a typical Futures fin 13 indicating the cant angle 14 between the fin 13 and base 10. canted fin in the fin fixing system according to the invention. A Futures fin 13 has been inserted into the Futures fin base 10, which has created a Futures fin angle at base 14.

[0081] FIG. 5 is a side and front view representation of a typical FCS fin 8 with and FCS fin base 9 which indicates an FCS fin with no cant angle at base 15.

[0082] FIG. 6 is a lateral cross section of the fin fixing system shown in FIG. 2. With The Futures fin 13 and base 10 inserted into the fin box 1. The Futures fin 13 has a canted angle, such that the Futures fin base 10 is not parallel to the direction of the Futures fin 13. The wedge 2 has been pulled back and down, by wedge adjustment screw 6 such that the channel 4 is available for the acceptance of the Futures base 10. Force from the grub screw 7 holds the fin 13 in place.

[0083] FIG. 7 is a top, perspective view of the fin fixing system of FIG. 6 showing the fin or adaptor not in the slot. On one side of the fin box 1 is the wedge 2 and wedge adjustment screws 6. On the other side are two grub screw holes 11 and an angled lock screw hole 16 which functions to provide access for a further grub screw to lock in the leading edge of the fin.

[0084] FIG. 8 is a top, perspective view of the fin fixing system of FIG. 7 showing the fin or adaptor not in the slot. This figure is identical to FIG. 7, except that the wedge 2 has been extended in this figure.

[0085] FIG. 9 is an angled perspective view of FIG. 6 of a Futures fin 13 being restrained in the fin box 1. The Futures fin 13 has a canted angle, such that the Futures fin base 10 is not parallel to the direction of the Futures fin 13. The wedge 2 has been pulled back and down, by force from the grub screw 7 holds the fin in place.

[0086] FIG. 10 is a an angled perspective view of FIG. 3 of an FCS fin 8 and base 9 being restrained in a fin box 1. The FCS fin base 9 resides in the parallel channel 3 created by the indent 5 and the wedge 2. The grub screw 7 is exerting pressure on the FCS fin base 9 to keep it in the channel 3. Wedge 2 has been activated by the wedge adjustment screw 6 and in cooperation with the indent 5 the channel 3 creates the required cant angle for FCS fin 8. Thereby creating the required cant angle for the FCS fin 8.

[0087] FIG. 11 is top view of the channel created for an FCS fin without the fin in the box. The wedge 2 is shown as encroached into the channel by the wedge adjustment screws (not shown) creating the required specifications in channel 3 for the insertion of an FCS fin.

[0088] FIG. 12 is a top view of the channel 4 for a Futures fin without the fin in the box. It shows the channel 4 available for insertion of a Futures fin without the fin in the box. The channel 4 is shown without the wedge 2 of FIG. 11.

[0089] FIGS. 13 through 14 are top views of an alternate embodiment of the fin box.

[0090] FIG. 15 is a top view of yet another embodiment of the fin box.

[0091] FIG. 16 is a side view of yet another embodiment of the fin box.

[0092] FIG. 17 is a top view yet another embodiment of the fin box.

[0093] FIG. 18 is a cross-sectional view of one embodiment of the invention. Drawing 18 indicates the FCS type fin 8 and base 9 being inserted into the box 1 the fin engages the clip/latch/button 22 at the engagement point 26 that starts pushing the clip/latch/button 22 into the cavity 24 compressing the resilient/compressible material spring 23 (shown un-compressed). The cap 25 provides an assembly access to the cavity 24. The channel 3 is provided by the wedge 2 being in the up position after being adjusted by the adjustment screw 6.

[0094] FIG. 19 is a cross-sectional view of one embodiment of the invention. Drawing 19 shows the fin 8 and base 9 encroaching further into the channel 3 and moving the clip/latch/button 22 further into the cavity 24 and compressing the spring 28 (shown being compressed therefore different number).

[0095] FIG. 20 is a cross-sectional view of one embodiment of the invention. Drawing 20 shows the fin 8 and base 9 encroaching to the point whereby the engagement point 26 is compressing the spring 28 to maximum compressed state.

[0096] FIG. 21 is a cross-sectional view of one embodiment of the invention. Drawing 21 show the fin 8 and base 9 having being fully inserted into the channel 3 and the spring 23 now fully un-compressed pushing the clip/latch/button 22 into the channel and occupy the space in the fin 27 thus locking the fin into place.

[0097] FIG. 22 is a cross-sectional view of one embodiment of the invention. Drawing 22 indicates Futures type fin 13 and base 10 being inserted into the channel 4 created by the withdrawal of wedge 2 by adjustment screw 6
