Removable fixing device

A removable fixing device (1) fixing equipment (A) on a support (B), an assembly comprising said equipment and said support being able to be disposed in an enclosure, such that said support (B) comprises a planar part which extends in a plane (P) and which corresponds with a complementary planar part of said equipment (A), said device comprising:

• an assembly rod (3) extending from the support along a rod axis (z) perpendicular to the plane and having a first end linked mechanically to said planar part of the support (B) and a second end;
• a compressible planar piece (5) disposed between the planar parts of the support and the equipment, the compressible planar piece and the planar part of the equipment each having an open slot for receiving the assembly rod therethrough;
• a two-branch fork (8) with an open slot defined between opposing teeth of the fork for receiving the assembly rod therethrough;
• an operating lever comprising a cam lever (2), the cam lever comprising two parallel identical cams, each rotatably mounted on the fork about a lever axis (y) perpendicular to the rod axis (z) of the assembly rod, the cams being situated on outer sides of the fork on opposing sides of the slot;
• and
• a tightening means (4) provided on said second end of the assembly rod (3) capable of being arranged in a tightened position for applying a clamping force against the fork;
• wherein said compressible planar piece (5), said planar part of the equipment (A), said fork (8), and said tightening means (4) arranged in the tightened position are successively disposed parallel to the plane (P) around said assembly rod (3) in an assemblage such that the tightening means applies a clamping force to the fork and the cams of the cam lever apply a clamping force to the planar part of the equipment to compress the compressible planar piece;
• and
• wherein said cam lever (2) is arranged so that a rotation of the cam lever (2) about the lever axis (y) induces a displacement of the earn lever (2) between a tightened position in which the compressible planar piece (5) is compressed and the assemblage is fixed, and a loosened position in which said assemblage is removable via removal of the assembly rod from the open slots of the fork, the equipment and the compressible planar piece;
• wherein each of the cams comprises, on its outer surface, a point of contact (M) with the equipment, said point (M) being displaced on said equipment and on the outer surface of said cam, during the displacement of the cam lever (2) from the tightened position to the loosened position;
• wherein the outer surface of each of the cams comprises a first part (10) and a second part (11) such that:
• when the cam lever (2) is in the tightened position, said first part of the outer surface of the cam (10) is in contact with the equipment at a distance (d) relative to the lever axis (y) and said first part of the outer surface of the cam compresses the compressible planar piece (5);
• during the displacement of the cam lever (2) from the tightened position to the loosened position, sad second part of the outer surface of the cam (11) is in contact with the equipment at least one point M which changes in approaching the lever axis (y);
• when the cam lever is in the loosened position, the distance (e) between said point (M) and the lever axis (y) is chosen so that the assemblage is removable.
