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, Kafe, Webinar 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.

초록

An oil filter change method and apparatus for use with Harley Davidson motorcycles employs a filter funnel adapted to fit beneath the oil filter prior to removal. A drain hose may be attached to a spout portion of the funnel, the filter is punctured, and oil allowed to drain therefrom. Once drained, the filter is fully removed, and is held in the funnel for removal, with minimal or no oil spillage onto the engine of the motorcycle.

1. A funnel for use in oil filter change operations, comprising: a filter receiving portion having a shape for placement adjacent a filter for capturing oil draining from the filter, said filter receiving portion having left and right upper edges along a region where said filter is received; andat least one contact surface area reduction member defined on an interior face of the filter receiving portion at a position away from the left or right upper edges, for reducing surface area of contact between an oil filter face and a surface of the funnel, to assist in allowing the filter to slide longitudinally in the funnel, by minimizing the surface area of contact between the surface of the funnel and the oil filter face. 2. The funnel according to claim 1, further comprising: a sealing surface for providing a temporary seal against an engine surface to assist in directing oil into the funnel. 3. The funnel according to claim 2, wherein said sealing surface comprises a substantially hemispherical region at an end of the funnel. 4. The funnel according to claim 1, further comprising: a drain channel formed as a depression along a longitudinal portion of an interior face of the funnel for directing draining oil away. 5. The funnel according to claim 1, wherein said contact surface area reduction member comprises a longitudinal rib extending along a portion of an inner face of the funnel. 6. The funnel according to claim 4, further comprising: a spout portion defined at an end of the drain channel for discharging oil from the drain channel. 7. The funnel according to claim 1, wherein said funnel is a motorcycle oil filter change funnel. 8. The funnel according to claim 7, wherein said motorcycle oil filter change funnel is adapted for use for changing oil on a HARLEY DAVIDSON brand motorcycle. 9. A method of changing an oil filter in a motorcycle, comprising the steps of: positioning, at a location of the oil filter, a funnel member having at least one at least one contact surface area reduction member, for reducing surface area of contact between an oil filter face and a surface of the funnel member, to assist in allowing the filter to slide longitudinally in the funnel member, by minimizing the surface area of contact between the surface of the funnel member and the oil filter face, said funnel member having an oil filter receiving portion having a shape for placement adjacent a filter for capturing oil draining from the filter, said funnel member having a drain channel formed as a depression along a longitudinal portion of an interior face of the funnel for directing draining oil away; andforming an opening in the oil filter near a peripheral edge of a face of the filter to allow oil to drain therefrom into the funnel. 10. The method according to claim 9, further comprising: said forming an opening step comprising piercing the oil filter to create a hole therein. 11. The method according to claim 9, further comprising the step of moving the oil filter to position the opening formed therein so as to be adjacent the funnel member. 12. The method according to claim 9, further comprising pressing a portion of said funnel member against a surface of the motorcycle to form a temporary seal against oil drainage at said portion. 13. The method according to claim 9, further comprising removing a dipstick and oil drain plug after said positioning and forming steps. 14. The method according to claim 9, further comprising, after oil has drained from said filter a desired amount, removing the filter from the motorcycle. 15. The method according to claim 9, further comprising directing oil away from said funnel through a drain tube. 16. The funnel according to claim 4 wherein said drain channel begins slightly inwardly of a filter end of the filter receiving portion. 17. The funnel according to claim 4 wherein said drain channel extends substantially a length of the funnel. 18. The method according to claim 9 wherein said drain channel begins slightly inwardly of a filter end of the oil filter receiving portion. 19. The method according to claim 9 wherein said drain channel extends substantially a length of the funnel member. 20. The funnel according to claim 1, wherein said contact surface area reduction member comprises a raised portion on the surface of the funnel. 21. A motorcycle oil filter change funnel for use with motorcycles, comprising: a filter receiving portion having a hemispherical shape for placement adjacent a filter for capturing oil draining from the filter;a sealing edge adapted for engagement with a filter seal surface of the motorcycle for providing a temporary seal against oil leakage along the sealing edge;plural rib members on an inner face of said funnel for minimizing surface area of contact between the inner face and the filter, to assist in allowing the filter to slide longitudinally in the filter receiving portion, by minimizing the surface area of contact between the surface of the filter receiving portion and the oil filter face; anda drain channel formed as a depression along a longitudinal portion of an interior face of the filter receiving portion for conveying away oil draining from the filter. 22. The motorcycle oil filter change funnel according to claim 21, further comprising a spout member at an end of the funnel opposite the sealing edge, for directing oil away from the funnel. 23. The motorcycle oil filter change funnel according to claim 21, further comprising a stop member for providing a stop against which the filter rests, to define a limit of longitudinal movement of the filter along an inner surface of the funnel. 24. The motorcycle oil change funnel according to claim 21 wherein said drain channel begins slightly inwardly of the sealing edge. 25. The motorcycle oil change funnel according to claim 21 wherein said drain channel extends substantially a length of the funnel. 26. The funnel according to claim 21, wherein said rib portions comprise raised portions on the inner face of the funnel.
