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, 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

A movable pullout step attachable to a vehicle and which has a spring actuated latching mechanism that selectively allows and restrains positioning of the pullout step in either a retracted position under the vehicle or a step position wherein a tread extends away from the vehicle to allow a person to stand thereon to facilitate the access to desired portions of the vehicle.

The arrangement defined in claim 1 wherein: each of said pair of guides comprises a generally “U” shaped guide member having an inner upright wall and an outer upright wall, and the base of said “U” shaped guide members fixedly connected to said base plate;said outer upright wall of a first of said pair of generally “U” guide members in regions adjacent to and extending substantially parallel to a first of said pair of side walls and said inner wall of said first of said pair of “U” shaped guide members spaced inwardly therefrom;each of said pair of rails comprises a generally box shaped rail member, and a first of said box shaped rail members slidingly movable in said first of said “U” shaped guide members and the second of said pair of box shaped rail members slidingly movable in the second of said “U” shaped guide members. 3. The arrangement defined in claim 2 wherein: said first of said pair of spaced apart rail apertures in said alignment with said guide aperture for said latch member in said first position thereof and said second of said pair of spaced apart rail apertures in said alignment with said guide aperture for said latch member in said second position thereof;said tread member has a manually graspable lip portion or allowing manual manipulation of said tread member between said retracted position thereof and said step position thereof for the condition of said latch member in said second position thereof. 4. The arrangement defined in claim 3 and further comprising: said outer wall of said first of said “U” shaped guide members having slot walls defining a retaining slot there through extending from regions adjacent said inner end thereof to regions spaced from said outer end thereof. 5. The arrangement defined in claim 4 and further comprising: an alignment pin extending through said first side wall and into said retaining slot. 6. The arrangement defined in claim 5 wherein: said base plate, said pair of side walls, said flange members and said spring stop are unitarily formed from sheet metal. 7. A retractable, pull-out step for a vehicle, comprising, in combination: a base plate;a tread mounted on said base plate and reciprocally movable thereon between a retracted position and a step position;a latching mechanism mounted on said base plate, said latching mechanism having: a lever pivotally mounted on said base plate and said lever having a latch member thereon having a first position for selectively restraining said tread in each of said retracted position and said step position thereof, and said latch member movable to a second position for selectively releasing said tread from said retracted position and said step position;wherein said lever further comprises a first arm and a second arm spaced from said first arm;a pivot mounting on said lever intermediate said first arm and said second arm; anda pivot pin mounted on said base plate and extending through said pivot mounting on said lever to allow pivotal movement of said lever thereon;a flexible cable having a first end operatively connected to said lever for selectively moving said latch member out of said first position to allow movement of said tread between said retracted position and said step position, and a second end, said second end spaced from said first end and said second end having a handle thereon;a spring means operatively connected to said lever for yieldingly resisting movement of said latch member out of said first position to said second position and urging said latch member into said first position, whereby pulling on said handle moves said cable to move said latch member from said first position thereof to said second position thereof. 8. The arrangement defined in claim 7 and further comprising: a spring stop mounted on said base plate and spaced from said second arm of said lever;a cable stop on said second arm of said lever, and said first end of said cable connected to said cable stop for movement therewith;said spring comprising a coil spring mounted around said cable between said spring stop and said cable stop to provide said yieldingly resisting movement of said latch member out of said first position to said second position and urging said latch member into said first position. 9. The arrangement defined in claim 8 and further comprising: a cable cover on said cable and said cable cover extending between said spring stop and said handle of said cable. 10. The arrangement defined in claim 9 and further comprising: a cable guide operatively connected to said base plate for restraining movement of said cable cover, whereby said cable cover is maintained in said position between said spring stop and said cable guide, and said cable moves in said cable cover. 11. The arrangement defined in claim 10 wherein: said cable cover further comprises: a first portion having a first end at said spring stop and a second end spaced from said cable guide;a second portion extending between said second end of said first portion of said cable and said cable guide, said second portion fixedly connected to said cable guide. 12. The arrangement defined in claim 11 and further comprising: said cable guide has an outer surface and an inner surface;said second portion of said cable cover fixedly connected to said inner surface of said cable guide and said handle abutting against, said outer surface of said cable guide for the condition of said latch member in said first position thereof. 13. The arrangement defined in claim 12 wherein: said handle is movable outwardly away from said cable guide to move said latch member from said first position thereof to said second position thereof. 14. The arrangement defined in claim 13 wherein: said second portion of said cable cover has a threaded section extending between said inner surface of said cable guide and said outer surface of said cable guide, and further comprising: a first stop threadingly engaging said threaded section and abutting against said inner surface of said cable guide; and,a second stop threadingly engaging said threaded portion and abutting against said outer surface of said cable guide for restraining said second portion against said cable guide. 15. The arrangement defined in claim 14 and further comprising: a manually graspable lip portion on said tread for moving said tread between said step position thereof and said retracted position thereof for the condition of said latch member in said second position thereof. 16. The arrangement defined in claim 15 wherein: said tread has an outer edge and an inner edge;said lip portion connected to said outer edge of said tread and extending downwardly therefrom; and further comprising:a toe stop connected to said inner edge of said tread and extending upwardly therefrom.
