Abstract:
1. A buckle mechanism for releasably and adjustably connecting an attachment member ( 3 ) to a tongue member ( 5 ), comprising a fixed buckle member ( 2 ) connected to or adapted for being connected to the attachment member ( 3 ), a movable element ( 4 ) that is adapted to be connected to the tongue member ( 5 ) and is slidably mounted inside the fixed buckle member ( 2 ) between a first stable position and a second stable position for varying a distance along a pulling direction between said tongue member ( 5 ) and said attachment member ( 3 ), and a manually-operable lever system ( 6 , 6 ′) for moving the movable element ( 4 ) between its first and second stable positions, characterized in that the manually-operable level system ( 6 , 6 ′) comprises an actuating lever ( 6 ) that is tiltable through about 180.degree. to move the movable element ( 4 ) between its first and second stable positions, and characterized in that the manually-operable lever system comprises a first lever member ( 6 ) pivotally connected to the movable element ( 4 ) about a first axis ( 7 ), said first lever member ( 6 ) being further pivotally connected to a second lever member ( 6 ′) about a second axis ( 8 ), the second lever member ( 6 ′) being pivotally connected to the fixed buckle member ( 2 ) about a third axis ( 9 ), the movable element ( 4 ) being able to slide between the first stable position and the second stable position with tilting of the lever member ( 6 ) through approximately 180 degrees by pivoting of the first lever member ( 6 ) about said first and second axes ( 7 , 8 ) while the second lever member ( 6 ′) pivots about the third axis ( 9 ).
