Claims17
A device for opening and closing a lid for opening and closing an opening of a housing, comprising:
- first link means having one end linked to a first end of one side edge of said housing and the other end linked to a second end of one side edge of said lid, said one side edge of said housing and said one side edge of said lid facing each other;
- and
- second link means extending parallel to said first link means and having one end like said one end of said first link means linked to a first end of said one side edge of said lid and the other end like said other end of said first link means linked to a second end of said one side edge of said housing, said first end of said housing and said first end of said lid facing each other, said second end of said housing and said second end of said lid facing each other;
- first locking means provided on said one side edge of said housing for locking said first ink means;
- and
- second locking means provided on said one side edge of said housing for locking said second link means.
A device for opening and closing a lid on a housing, said device comprising:
- a first link having a first end rotatably fixed to said housing and a second end rotatably fixed to said lid;
- and
- a second link having a first end rotatably fixed to said lid and a second end rotatably fixed to said housing;
- said first link being pivotable about said first end of said first link while said second link is held stationary with respect to said housing, thereby allowing said lid to be opened to a first open position, and
- said second link being pivotable about said second end of said second link while said first link is held stationary with respect to said housing, thereby allowing said lid to be opened to a second open position.
A housing having a lid alternatively pivotable about first and second pivot axes, comprising:
- a first link having a first end rotatably fixed to said housing allowing said first link to be pivoted about said first pivot axis, said first link also having a second end rotatably fixed to said lid allowing said lid to be pivoted relative to said first link about said second pivot axis;
- a second link having a first end rotatably fixed to said lid allowing said lid to be pivoted relative to said second link about said first pivot axis, said second link also having a second end rotatably fixed to said housing so as to allow said second link to be pivoted about said second pivot axis;
- wherein said second link is maintained in a fixed relationship with respect to said housing and said first link is pivoted about said first pivot axis to open said lid to a first open position, and wherein said first link is maintained in a fixed relationship with respect to said housing and said second link is pivoted about said second pivot axis to open said lid to a second open position.
