Abstract
Abstract A structure for mounting fins to the under side of a surfboard includes an elongated molded fin socket member which defines an interior rectangular slot configured to receive a rectangular base of a fin member. The fin socket further defines an upwardly extending cover recess coextensive with the slot. The fin socket is adhesively secured within a contoured recess within the surfboard foam core prior to the laminating operation. After the surfboard has been laminated with the fin socket in place such that the laminating materials overlap the fin socket, the upwardly extending portion of the fin socket is removed and ground flush to the laminated surface of the surfboard to expose the rectangular slot. Thereafter, the fin is adhesively secured within the slot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
For use in permanently securing a surfboard fin having a base portion to a surfboard wherein the surfboard defines a bottom surface and an elongated recess having a side surface and a top surface at the desired location of the surfboard fin, a surfboard fin socket comprising: an elongated housing defining an upper surface, a side surface joined thereto, said upper and said surfaces being configured to be received within the elongated recess of the surfboard; an outwardly extending flange forming a portion of a lower surface of said housing; and an elongated internal cavity within said housing extending above said flange and configured to receive the base portion of the surfboard fin in an adhesive bonding attachment.
Claim 2
Dependent Claim
118 words
For use in permanently securing a surfboard fin having a base portion to a surfboard wherein the surfboard defines a bottom surface and an elongated recess having a side surface and a top surface at the desired location of the surfboard fin, a surfboard fin socket comprising: an elongated housing defining an upper surface, a side surface joined thereto, said upper and said surfaces being configured to be received within the elongated recess of the surfboard; an outwardly extending flange forming a portion of a lower surface of said housing; and an elongated internal cavity within said housing extending above said flange and configured to receive the base portion of the surfboard fin in an adhesive bonding attachment.
Claim 3
Dependent Claim
32 words
A surfboard fin socket as set forth in claim 1 wherein said flange is positioned with respect to said bottom surface such that said flange is substantially flush with said surfboard surface.
Claim 4
Dependent Claim
59 words
A surfboard fin socket as set forth in claim 2 wherein said upper surface of said housing is substantially planar and wherein said side surface defines a continuous inclined wall surface joined to said upper surface and forming an outwardly extending surface configured to be received within said elongated recess of said surfboard and terminating in a lower edge.
Claim 5
Dependent Claim
27 words
A surfboard fin socket as set forth in claim 3 wherein said flange extends to and is joined to said lower edge of said inclined side wall.
Claim 6
Dependent Claim
24 words
A surfboard fin socket as set forth in claim 4 wherein said flange defines an exterior surface and a plurality of raised ribs thereon.
Claim 7
Dependent Claim
27 words
A surfboard fin socket as set forth in claim 5 wherein said elongated internal cavity includes an extension and a cover forming a closure of said cavity.
Claim 8
Dependent Claim
106 words
For use in securing a surfboard fin to a surfboard fabricated by laminating a plurality of laminations, a shaped core wherein the surfboard core defines a bottom surface and an elongated recess at the desired location of the surfboard fin, the combination comprising: a surfboard fin defining a fin member and a mounting base having a continuous outer surface; a socket housing configured to be received within said elongated recess of said surfboard core prior to the lamination of said core, said socket defining an extending cavity configured to receive said mounting base of said surfboard fin in a permanent adhesive attachment to said outer surface.
Claim 9
Dependent Claim
106 words
For use in securing a surfboard fin to a surfboard fabricated by laminating a plurality of laminations, a shaped core wherein the surfboard core defines a bottom surface and an elongated recess at the desired location of the surfboard fin, the combination comprising: a surfboard fin defining a fin member and a mounting base having a continuous outer surface; a socket housing configured to be received within said elongated recess of said surfboard core prior to the lamination of said core, said socket defining an extending cavity configured to receive said mounting base of said surfboard fin in a permanent adhesive attachment to said outer surface.
Claim 10
Dependent Claim
49 words
The combination set forth in claim 7 wherein said laminations of said surfboard are applied to said core after said socket housing is assembled within said elongated recess such that said laminations extend over a portion of said socket housing and wherein said extending cavity extends beyond said laminations.
Claim 11
Dependent Claim
24 words
The combinations set forth in claim 8 wherein said extending cavity includes a closed portion which is removed after said lamination are in place.
Claim 12
Independent Claim
148 words
A method of mounting a surfboard fin to a surfboard fabricated by laminating a shaped core wherein the surfboard core defines a bottom surface comprising the steps of: cutting a contoured recess within the surfboard core at the desired location of the fin; adhesively securing a surfboard fin socket within said contoured recess, said socket defining an internal extending elongated cavity extending beyond said bottom surface; applying one or more lamination layers of fiberglass and fiberglass resin to said surfboard core such that said socket is secured beneath the laminations with the extending elongated cavity extending above the lamination surface; removing a portion of the extending elongated cavity and a portion of the surrounding lamination material such that the elongated cavity is substantially flush with the surface of the lamination material; and assembling a fin member by adhesive assembly within the elongated cavity of the fin mounting socket.
