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.

A manual release mechanism for disengaging a king pin on a truck trailer from a fifth wheel of a truck cab includes a substantially straight lever arm with a first end being pivotally attached to the fifth wheel and a second end being spaced away from the fifth wheel extending horizontally from the first end. A pair of flat disks and a pair of slide bars are provided for slideably coupling to a release rod of the fifth wheel, such that a manual movement of the second end of the lever arm will cause pivoting thereof horizontally about the first end, thereby causing the release rod to be pulled outwardly to disengage the king pin from the fifth wheel. The lever arm is provided with an adjustable extension arm so that the length of the lever arm can be adjusted to an extent desired to best facilitate manipulation thereof. A lock pin is provided for securing the extension arm to the lever arm. A flexible cable secures the extension arm to the frame of the truck cab.

We claim: 1. A manual release mechanism for attachment to a fifth wheel of a truck cab for disengaging a king pin on a truck trailer combination from such fifth wheel of a truck cab, such fifth wheel having an elongated release rod extending outwardly therefrom through an opening in a side wall of such fifth wheel and adapted to be pulled outwardly to disengage such king pin from such fifth wheel, said manual release mechanism comprising: a) a lever arm having a predetermined length, a first end pivotally attachable to such fifth wheel at a location spaced from such opening through which such release rod extends and a second end spaced away from such fifth wheel extending generally horizontally from said first end; and b) a means engageable with said lever arm intermediate said first end and said second end for slideably coupling said lever arm to such elongated release rod such that a manual movement of said second end of said lever arm will cause said lever arm to be pivoted generally horizontally about said first end to cause such release rod to be pulled outwardly from such fifth wheel sufficient to disengage such king pin from such fifth wheel, wherein said means for slideably coupling said lever arm to such elongated release rod includes a first member disposed generally horizontally and abutting said lever arm and a second member disposed generally horizontally and abutting said lever arm opposite said first member, said first and second members extending past a predetermined width of said lever arm, said first and second members include at least one pair of mating and opposed apertures for attachment of said first member to said second member and to an end of such release rod disposed intermediate said first and second members, said first and second members adapted for slidable movement along at least a portion of said lever arm sufficient to disengage such king pin from such fifth wheel. 2. A manual release mechanism, according to claim 1, wherein said first and second members are generally flat and generally round. 3. A manual release mechanism, according to claim 1, wherein said manual release mechanism includes a predetermined plurality of said pairs of said mating and opposed apertures disposed in a predetermined pattern. 4. A manual release mechanism, according to claim 1, wherein said means for slideably coupling said lever arm to such elongated release rod further including a first slider bar rigidly attached to a first longitudinal edge of said lever arm and abutting said first member and a second slider bar rigidly attached to an opposite longitudinal edge of said lever arm parallel to said first slider bar and abutting said second member, said first and second slider bars forming a gap for receiving said end of such release rod. 5. A manual release mechanism, according to claim 1, wherein said means for slideably coupling said lever arm to such elongated release rod further includes a guide means abutting said lever arm opposite said end of such release rod, said guide means pivotally attached to said first and second members. 6. A manual release mechanism, according to claim 1, wherein said manual release mechanism further includes a visual indication means disposed for ease of distant recognition of said manual release mechanism and a status thereof in one of an engaged position and a disengaged position. 7. A manual release mechanism, according to claim 6, wherein said visual indication means is a reflective tape for easy identification at night. 8. A manual release mechanism for attachment to a fifth wheel of a truck cab for disengaging a king pin on a truck trailer combination from such fifth wheel of a truck cab, such fifth wheel having an elongated release rod extending outwardly therefrom through an opening in a side wall of such fifth wheel and adapted to be pulled outwardly to disengage such king pin from such fifth wheel, said manual release mechanism comprising: a) a lever arm having a predetermined length, a first end pivotally attachable to such fifth wheel at a location spaced from such opening through which such release rod extends and a second end spaced away from such fifth wheel extending generally horizontally from said first end; and b) a means engageable with said lever arm intermediate said first end and said second end for slideably coupling said lever arm to such elongated release rod such that a manual movement of said second end of said lever arm will cause said lever arm to be pivoted generally horizontally about said first end to cause such release rod to be pulled outwardly from such fifth wheel sufficient to disengage such king pin from such fifth wheel, wherein said means for slideably coupling said lever arm to such elongated release rod includes a link having a first portion with at least one first aperture for connection to said end of such release rod, a second portion outwardly extending from one end of said first portion, a third portion extending from a second end of said first portion parallel to said second portion, said second and third portions forming an open end and including at least one pair of mating and opposed second apertures for attachment to said lever arm, and a forth portion substantially closing said open end of said link. 9. A manual release mechanism, according to claim 8, wherein said means for slideably coupling said lever arm to such elongated release rod further includes a guide means attached to said fourth portion, said guide means manufactured from a polymer material having a low friction coefficient.
