연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

What is claimed is: 1. A skateboard comprising, in combination: a board having a tip portion and a tail portion; a substantially U-shaped first aperture formed in the tip portion and defining a first cantilever, an open end of the first aperture opening toward a central portion of the board; and a substantially U-shaped second aperture formed in the tail portion and defining a second cantilever, an open end of the second aperture opening toward a central portion of the board. 2. The skateboard of claim 1, wherein the board comprises a plurality of layers laminated together. 3. The skateboard of claim 1, wherein the board comprises a core layer, a first inner layer adjacent an upper surface of the core layer, a second inner layer adjacent a lower surface of the core layer, a first outer layer adjacent an upper surface of the first inner layer, and a second outer layer adjacent a lower surface of the second inner layer. 4. The skateboard of claim 3, wherein the core layer is formed of a foam material. 5. The skateboard of claim 3, wherein the first and second inner layers are each formed of fiberglass. 6. The skateboard of claim 3, wherein the first and second inner layers are each formed of wood. 7. The skateboard of claim 3, wherein the first and second outer layers are each formed of wood. 8. The skateboard of claim 1, further comprising a spine positioned within the board. 9. The skateboard of claim 8, wherein the spine is comprised of a carbon fiber composite. 10. The skateboard of claim 8, wherein the spine extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture. 11. The skateboard of claim 8, wherein the spine comprises an elongate first portion that extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture; a substantially figure-eight shaped second portion that extends around a first peripheral lip defined by the first aperture and around a second peripheral lip defined by the second aperture; and a pair of elongate lateral portions, each of which is positioned outward of the first portion and is connected at opposed ends thereof to the substantially figure-eight shaped second portion. 12. The skateboard of claim 1, wherein the board comprises a spine, a pair of inner layers adjacent the spine, and a pair of outer layers adjacent the inner layers. 13. A skateboard assembly comprising, in combination: a board having a tip portion and a tail portion; a first truck secured to the tip portion of the board and having an axle and a wheel rotatably secured to each end of the axle; a second truck secured to the tail portion of the board and having an axle and a wheel rotatably secured to each end of the axle; a substantially U-shaped first aperture formed in the board and defining a first cantilever and substantially surrounding the first truck, an open end of the first aperture opening toward a central portion of the board; and a substantially U-shaped second aperture formed in the board and defining a second cantilever and substantially surrounding the second truck; an open end of the second aperture opening toward a central portion of the board. 14. The skateboard assembly of claim 13, wherein the board comprises a plurality of layers laminated together. 15. The skateboard assembly of claim 13, wherein the board comprises a core layer, a first inner layer adjacent an upper surface of the core layer, a second inner layer adjacent a lower surface of the core layer, a first outer layer adjacent an upper surface of the first inner layer, and a second outer layer adjacent a lower surface of the second inner layer. 16. The skateboard assembly of claim 15, wherein the core layer is formed of a foam material. 17. The skateboard assembly of claim 15, wherein the first and second inner layers are each formed of fiberglass. 18. The skateboard assembly of claim 15, wherein the first and second inner layers are each formed of wood. 19. The skateboard assembly of claim 15, wherein the first and second outer layers are each formed of wood. 20. The skateboard assembly of claim 13, further comprising a spine positioned within the board. 21. The skateboard assembly of claim 20, wherein the spine extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture. 22. The skateboard assembly of claim 20, wherein the spine comprises an elongate first portion that extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture; a substantially figure-eight shaped second portion that extends around a first peripheral lip defined by the first aperture and around a second peripheral lip defined by the second aperture; and a pair of elongate lateral portions, each of which is positioned outward of the first portion and is connected at opposed ends thereof to the substantially figure-eight shaped second portion. 23. The skateboard assembly of claim 20, wherein the spine is comprised of a carbon fiber composite. 24. The skateboard assembly of claim 13, wherein the board comprises a spine, a first inner layer adjacent an upper surface of the spine, a second inner layer adjacent a lower surface of the spine, a first outer layer adjacent an upper surface of the first inner layer, and a second outer layer adjacent a lower surface of the second inner layer. 25. A skateboard comprising, in combination: a board having a tip portion and a tail portion, the board comprising a core layer; a first inner layer adjacent an upper surface of the core layer; a second inner layer adjacent a lower surface of the core layer; a first outer layer adjacent an upper surface of the first inner layer; and a second outer layer adjacent a lower surface of the second inner layer; a spine positioned within the board; a substantially U-shaped first aperture formed in the tip portion and defining a first cantilever, an open end of the first aperture opening toward a central portion of the board; and a substantially U-shaped second aperture formed in the tail portion and defining a second cantilever, an open end of the second aperture opening toward a central portion of the board. 26. The skateboard of claim 25, wherein the spine is comprised of a carbon fiber composite. 27. The skateboard of claim 25, wherein the spine extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture. 28. The skateboard of claim 25, wherein the spine comprises an elongate first portion that extends from the first cantilever defined by the first aperture to the second cantilever defined by the second aperture; a substantially figure-eight shaped second portion that extends around a first peripheral lip defined by the first aperture and around a second peripheral lip defined by the second aperture; and a pair of elongate lateral portions, each of which is positioned outward of the first portion and is connected at opposed ends thereof to the substantially figure-eight shaped second portion.
