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.

1. A leverage device comprising: (a) an elongated mounting bracket having a first end portion and a second end portion;(b) an actuating lever having a first end portion and a second end portion, said actuating lever being pivotally attached at said first end portion thereof to said first end portion of said mounting bracket to thereby form a pivotal attachment between said actuating lever and said mounting bracket;(c) a first linkage member having a first end portion and a second end portion, said first linkage member being pivotally attached at said first end portion thereof to said actuating lever, said first linkage member being pivotally attached to said actuating lever at a location spaced apart from said pivotal attachment between said actuating lever and said mounting bracket;(d) a second linkage member having a first end portion and a second end portion, said second linkage member being pivotally attached at said first end portion thereof to said second end portion of said first linkage member to thereby form a pivotal attachment between said first linkage member and said second linkage member, said pivotal attachment between said first linkage member and said second linkage member being supported for rectilinear motion relative to said mounting bracket by said mounting bracket;(e) a cam having a projecting finger and being rotationally supported by said mounting bracket at said second end portion of said mounting bracket for rotational motion about an axis of rotation, said second linkage member being pivotally attached at said second end portion thereof to said cam at a location offset from said axis of rotation of said cam,wherein pivotal movement of said actuating lever between a folded-down position and a fully raised position causes rotation of said cam between a first position and a second position. 2. The leverage device of claim 1, wherein said mounting bracket is adapted for mounting to a first member and wherein said cam is capable of engaging a second member such that the leverage device forces the first member into a final installed position relative to the second member during movement of said actuating lever from said fully raised position to said folded-down position. 3. The leverage device of claim 2, wherein said projecting finger of said cam engages an opening in the second member. 4. The leverage device of claim 2, wherein said mounting bracket is a first mounting bracket, said actuating lever is a first actuating lever, and said cam is a first cam, and said leverage device further comprises: a second elongated mounting bracket having a first end portion and a second end portion;a second actuating lever having a first end portion and a second end portion, said second actuating lever being pivotally attached at said first end portion thereof to said first end portion of said second mounting bracket to thereby form a pivotal attachment between said second actuating lever and said second mounting bracket;a third linkage member having a first end portion and a second end portion, said third linkage member being pivotally attached at said first end portion thereof to said second actuating lever, said third linkage member being pivotally attached to said second actuating lever at a location spaced apart from said pivotal attachment between said second actuating lever and said second mounting bracket;a fourth linkage member having a first end portion and a second end portion, said fourth linkage member being pivotally attached at said first end portion thereof to said second end portion of said third linkage member to thereby form a pivotal attachment between said third linkage member and said fourth linkage member, said pivotal attachment between said third linkage member and said fourth linkage member being supported for rectilinear motion relative to said second mounting bracket by said second mounting bracket;a second cam having a projecting finger and being rotationally supported by said second mounting bracket at said second end portion of said second mounting bracket for rotational motion about an axis of rotation, said fourth linkage member being pivotally attached at said second end portion thereof to said second cam at a location offset from said axis of rotation of said second cam; anda handle extending between said second end portion of said first actuating lever and said second end portion of said second actuating lever such that said handle, said first actuating lever, and said second actuating lever move as a unit,wherein pivotal movement of said handle, said first actuating lever, and said second actuating lever between a folded-down position and a fully raised position causes rotation of each of said first cam and said second cam between a first position and a second position. 5. The leverage device of claim 2, wherein said actuating lever is pivotally attached to said mounting bracket by a pin passing through an elongated opening provided in said first end portion of said actuating lever such that said actuating lever can move between said folded-down position and an intermediate position without causing any movement of said second linkage member and of said cam. 6. The leverage device of claim 4, wherein said handle, said first actuating lever, and said second actuating lever form a lever assembly, wherein said first actuating lever is pivotally attached to said first mounting bracket by a first pin passing through a first elongated opening provided in said first end portion of said first actuating lever, and wherein said second actuating lever is pivotally attached to said second mounting bracket by a second pin passing through a second elongated opening provided in said first end portion of said second actuating lever, such that said lever assembly can move between said folded-down position and an intermediate position without causing any movement of said second linkage member, said first cam, said fourth linkage member, and said second cam. 7. The leverage device of claim 6, further comprising a push-button latch that is capable of attachment to the first member and engaging said handle to selectively secure said lever assembly in said folded-down position. 8. The leverage device of claim 7, said push-button latch further comprising a pawl that is capable of engaging the second member when said lever assembly is in said fully raised position so as to aid in maintaining the first member in a proper position relative to the second member for engagement of the first and second cams with the second member as the lever assembly is moved to the folded-down position.
