Patent ID: 8590590

Claim:
A machine for fitting and removing a tire ( 1 ) from a rim ( 2 ) of a wheel ( 3 ) comprising a frame ( 10 ), a table ( 11 ) capable of having the rim attached thereto and of rotating said rim in a centered manner about an axis (Y) and a lever ( 12 ) articulated on the frame ( 10 ), said lever ( 12 ) comprising a control point (A), a pressure element ( 13 ) for exerting a pressure on a bead ( 6 ) and/or a wall ( 5 ) of the tire at a working point (B) of the tire, a first articulation about a point (C) in order to bring the pressure element ( 13 ) closer to or further from the axis (Y), and a second articulation about a point (E) in order to bring the pressure element ( 13 ) closer to or further from a central plane (PC) perpendicular to the axis (Y) and passing through a center (D) of the rim, a radial plane (PR) comprises the axis (Y) and the point (B), a tangential plane (PTA) is parallel to the axis (Y), is perpendicular to the radial plane (PR) and comprises the point (B), the radial plane (PR) and the tangential plane (PTA) define four successive spatial quadrants (Q 1 ,Q 2 ,Q 3 ,Q 4 ) of which the first quadrant (Q 1 ) is that immediately following the axis (Y) in the direction of rotation of the rim ( 2 ), wherein the point (C) is in the first quadrant (Q 1 ) or in the third quadrant (Q 3 ).
