These two crosspieces also have a U-shaped cross section. Relative to the quadrangular opening determined by the frame, the wings of the profiles constituting the uprights 2 and the crosspieces are parallel to the plane of the opening and oriented opposite the latter. while the web of these sections is perpendicular to the plane of said opening. More precisely, the opening is delimited on the left and on the right by the upper surface of the core of the left and right uprights and above and below by the upper surface of the core of the upper and lower crosspieces.
• the quadrangular opening as defined receives shutters 4 of generally rectangular shutter each mounted in attachment to a rotary bar 3. Horizonating with an actuating mechanism which is mounted in the vertical housing formed by one of the uprights.
• each flap is offset from its bar so that its center of gravity is also offset from the axis of rotation of its bar. Behind the bar, the flap forms a heel. In the closed position, the flaps overlap each other and extend downward from their bar. Still in this closed position, the heel of each flap develops above the corresponding bar and is covered by the lower part of the flap positioned immediately above. Such a closed position is shown in Figure 9. In the open position the flaps develop perpendicular to the opening.
• Each pivot piece 9 passes right through the wall 13 of the corresponding upright by passing through the bearing 13A and comprises a stud 11 engaged and locked in a housing 12 formed in the corresponding end of the bar, said housing being of complementary shape to that of the tenon, a cylindrical bearing 9A axially extending said tenon cooperating in guiding in rotation with the bearing 13A and an end portion 9B axially extending the cylindrical bearing 9A in the vertical housing formed by the corresponding upright and separated from the latter by a shoulder constituting stop and opposing the passage of the terminal part 9B through the bearing 13A.

Furthermore, the assembly is removably attached to said upright. Furthermore, the link 21 is not fixed to the hinge pin 31 but only engaged on the latter. Thus, by lateral movement of the housing, taking the dimensions of the opening 27 into account, it is possible to disengage the link 21 from the axis 31 and to proceed with the removal of the engine assembly with a view to its replacement or replacement. repair.
