Abstract
A cantilever includes a spar connected rotatably about a rear fixed axis to a fastening device for a vehicle, a tool lever connected rotatably about a front fixed axis to the spar, a deflecting triangle connected rotatably about a central fixed axis to the spar, a rear strut connected rotatably about a first strut pivot axis to the fastening device and rotatably about a second strut pivot axis to the deflecting triangle, a front strut connected rotatably about a third strut pivot axis to the deflecting triangle and rotatably about a fourth strut pivot axis to the tool lever. The rear and the central fixed axis span a first plane. The rear strut intersects the first plane. The central and the front fixed axis span a second plane. The front strut intersects the second plane.
Claims11
A cantilever (1), for a vehicle, the cantilever comprising:
- a fastening device (5) that fastens the cantilever to the vehicle,
- the fastening device including a rear fixed axis (4) and a first strut pivot axis (12);
- a spar (3) having a front end and a rear end,
- the rear end of the spar being connected so as to rotate around the rear fixed axis (4) with the fastening device (5),
- the spar having a sharp bend (22) located between the front end and the rear end,
- the sharp bend (22) having an inner side and an outer side,
- the front end of the spar including a front fixed axis (7);
- a deflecting triangle (8) located in an area of the sharp bend (22),
- the deflecting triangle (8) including a central fixed axis (9), a second strut pivot axis (13), and a third strut pivot axis (15),
- the deflecting triangle (8) being connected so as to rotate around the central fixed axis (9) with the spar (3);
- a tool lever (6) connected so as to rotate around the front fixed axis (7) with the spar (3),
- the tool lever (6) including a fourth strut pivot axis (16);
- a rear strut (11) connected so as to rotate around the first strut pivot axis (12) with the fastening device (5) and so as to rotate around the second strut pivot axis (13) with the deflecting triangle (8);
- and
- a front strut (14) connected so as to rotate around the third strut pivot axis (15) with the deflecting triangle (8) and so as to rotate around the fourth strut pivot axis (16) with the tool lever (6),
- wherein the rear fixed axis (4) and the central fixed axis (9) span a first plane,
- wherein the rear strut (11) intersects the first plane,
- wherein the central fixed axis (9) and the front fixed axis (7) span a second plane,
- wherein the front strut (14) intersects the second plane,
- wherein the central fixed axis (9) is arranged at a first distance from the inner side of the sharp bend (22),
- wherein the second strut pivot axis (13) is at a second distance from the inner side of the sharp bend (22),
- the third strut pivot axis (15) is arranged at a third distance from the inner side of the sharp bend (22),
- wherein the first distance is less than the second distance and the first distance is less than the third distance so that the second and third strut pivot axes (13, 15) are arranged at a greater distance from the inner side of the sharp bend than the first distance at which the central fixed axis (9) is arranged from the inner side of the sharp bend, and
- wherein the rear and front struts (11, 14) are arranged entirely inside the spar (3).
A cantilever (1), for a vehicle, the cantilever comprising:

- the rear end of the spar being connected so as to rotate around the rear fixed axis (4) with the fastening device (5),
- the spar having a sharp bend (22) located between the front end and the rear end,
- the sharp bend (22) having an inner side and an outer side,
- the front end of the spar including a front fixed axis (7);
- a deflecting triangle (8) located in an area of the sharp bend (22),
- the deflecting triangle (8) including a central fixed axis (9), a second strut pivot axis (13), and a third strut pivot axis (15),
