Abstract (en)
The device comprises a rack 3, integral with a bar 4 and in alignment therewith, two rods 5 and 6, respectively, side-by-side in a longitudinal plane, each provided at the lower extremity with a corresponding transverse tailpiece 13 able to move axially from a non-operative to an operative position and vice versa, as well as to oscillate longitudinally from an internal position I to an external position E and vice versa, transverse abutment means 16a and 16b, respectively, that define, in cooperation with elastic means 17, the said internal position I of the rods 5 and 6, and to conclude, a transverse slide 18 that is positioned in between the said rods and is able to move alternately, in a longitudinal direction, between two extreme positions M and K, respectively. When one rod is in the operative position, the tailpiece 13 of this is inserted in a space 3b in between two teeth 3a of the rack 3. The displacement of the slide 18 in one direction causes the interception thereof with the rod that is in the operative position and, consequently, the rack 3 to be carried in the said direction.
