Abstract

A rotor 10 of a centrifuge 100 having a rotor axis R, a receiving space 18 for samples to be centrifuged, a lid 40 which limits the receiving space 18 at the top, which is concentrically mounted relative to the rotor and which has, on its side remote from the receiving space 18, a handle 44 for carrying the rotor and the lid 40, and a locking mechanism of lid 40 and rotor, which mechanism is mounted in a support 52, 54 in the lid 40, said locking mechanism 50, 34b comprising a locking element 50 adapted to be movable between a locking position and an unlocking position and which has an actuating member 56 and a latching element 58, with the actuating member 56 and the latching element 58 being axially spaced from each other relative to the rotor axis R. The invention is characterized in that the locking element 50 is formed by a tilt lever which has the actuating member 56 mounted on its upper end and the latching element 58 mounted on its lower end, with its pivot axis being aligned perpendicular to the rotor axis R.

First claim

What claimed is:

1. A rotor ( 10 ) of a centrifuge ( 100 ), comprising:
a rotor axis (R);
a receiving chamber ( 18 ) in said rotor for a sample container to be centrifuged;
said receiving chamber includes a top;
a pin ( 34 );
said pin ( 34 ) resides in said receiving chamber ( 18 );
said pin ( 34 ) is coaxial with said rotor axis (R);
said pin includes recess ( 34 b ) for engaging a latching element ( 58 );
a lid ( 40 );
said lid ( 40 ) resides at said top of said receiving chamber ( 18 );
said lid ( 40 ) is concentrically mounted relative to said rotor;
a handle ( 44 ) for carrying said rotor and said lid ( 40 );
said handle ( 44 ) mounted remotely with respect to said receiving chamber ( 18 );
a locking mechanism for locking said lid ( 40 ) to said rotor;
said lid includes an aperture ( 42 a );
said pin ( 34 ) at least partly engages said handle ( 44 ) through said aperture ( 42 a ) in said lid ( 40 );
a support ( 52 , 54 ) in said lid ( 40 );
said locking mechanism is mounted in said support ( 52 , 54 ) in said lid ( 40 ), and said locking mechanism is adapted to be movable between a locking position when said lid is affixed to said rotor and an unlocking position when said lid is not affixed to said rotor;
said locking mechanism comprises:
a tilt lever ( 50 ), said tilt lever includes an upper end, a lower end, and a pivot axis aligned perpendicular to said rotor axis (R);
an actuating member ( 56 ) and said latching element ( 58 );
said actuating member ( 56 ) resides on said upper end of said tilt lever ( 50 ) and a latching element ( 58 ) resides on said lower end of said tilt lever ( 50 ), said actuating member ( 56 ) and said latching element ( 58 ) being axially spaced from each other relative to said rotor axis (R), and, said tilt lever being rotatable about said pivot axis enabling locking of and unlocking of said lid and said rotor.

2. A rotor ( 10 ) of a centrifuge ( 100 ), comprising:
a rotor axis (R);
a receiving chamber ( 18 ) in said rotor for a sample container to be centrifuged;
said receiving chamber includes a top;
a pin ( 34 );
said pin ( 34 ) has an end;
said pin ( 34 ) resides in said receiving chamber ( 18 );
said pin ( 34 ) is coaxial with said rotor axis (R);
said pin ( 34 ) includes a coaxial shoulder ( 35 );
said pin is partially conical and tapers toward said end;
said pin ( 34 ) includes a recess ( 34 b ) for engaging a latching element ( 58 ) of a tilt lever ( 50 );
a seal ( 43 ) is mounted in said coaxial shoulder and surrounds said pin ( 34 );
a lid ( 40 );
said lid resides at said top of said receiving chamber ( 18 );
said lid is concentrically mounted relative to said rotor;
said lid ( 40 ) includes an aperture ( 42 a ) therein;
a support ( 52 , 54 ) in said lid ( 40 );
a handle ( 44 ) for carrying said rotor and said lid ( 40 );
said handle ( 44 ) is mounted remotely with respect to said receiving chamber ( 18 );
a locking mechanism ( 50 , 34 b ) for locking said lid ( 40 ) to said rotor;
said locking mechanism is mounted in said support ( 52 , 54 ) in said lid ( 40 );
said locking mechanism is adapted to be movable between a locking position when said lid is affixed to said rotor and an unlocking position when said lid is not affixed to said rotor;
said locking mechanism comprises:
said tilt lever ( 40 ) includes an upper end, a lower end, and a pivot axis aligned perpendicular to said rotor axis (R);
an actuating member ( 56 ) and said latching element ( 58 );
said actuating member resides on said upper end of said tilt lever and said latching element resides on said lower end of said tilt lever, said actuating member ( 56 ) and said latching element ( 58 ) being axially spaced from each other relative to said rotor axis (R), and, said tilt lever being rotatable about said pivot axis enabling locking of and unlocking of said lid and said rotor;
said lid ( 40 ), when in said locking position, abuts and engages said seal ( 43 );
said seal ( 43 ) is adapted to seal said receiving chamber ( 18 ) of said rotor from said pin ( 34 ); and,
said seal ( 43 ) is adapted to seal receiving chamber ( 18 ) of said rotor from said aperture ( 42 a ) of said lid ( 40 ).
