• This force of pressure is directed towards the interior of the basket 120 and will deform each flexible tongue 128 so that the basket 120 can continue its movement through the reception opening 115 of the frame 107.
• a pressing force is again exerted in contact of the stop rim 125A of each flexible tab 128 with the frame 107.
• each flexible tab 128 protrude from the frame 107 to end up in line with the panels 118 (FIG. 8).
• the top of each flexible tab 128 extending between the other ratchet tooth 125B and the stop flange 125A is located opposite the accessibility window 118A of the panel 118.
• Each tab flexible 128 remains subjected to a pressure moving it away from its position of stable equilibrium, thanks for example here to the contact between the upper edge of the accessibility window 118A and the corresponding stop rim 125A (see FIG. 8).
• each flexible tongue 128 resiliently return to their position of. stable equilibrium.
• the latching tooth 119 of each panel 118 hooks to the hooking edge 129A of the hooking window 129 provided in each flexible tongue 128 of the wall. side 127 of the basket 120.
• the other latching tooth 125B of each flexible tongue 128 hooks onto the other hooking edge 118D provided in each panel 118 of the frame 107.
• the basket 120 is therefore assembled by double snapping the flexible tongues 128 of the basket 120 onto the flaps 118 of the frame 107.
• a further inward movement of the basket 120 increases the retention of the basket 120 on the frame 107 by the abutment of the abutment flange 125A of each flexible tongue 128 with the abutment edge 111A provided in each panel 118 of the frame 107 ( figure 10).
• the fitting mechanism 20, 30 can then be introduced therein.
• the disassembly of the basket 120; 220 is carried out from the front of the frame 107 by sequential pinching of each flexible tongue 128; 228 towards the interior of the reception opening 115. This disassembly is carried out after having removed the fitting mechanism 20; 30 of the device support 100.
• the pinching of the flexible tongues 128; 228 is here produced by the introduction of a tool inside the housing for receiving the basket 120; 220.
• This tool is introduced into the accessibility window 118A of each panel 118 in order to disengage the stop flange 125A from the corresponding flexible tongue 128 of the stop edge 111A of the panel 118.
• the disengagement of each stop flange 125A also results in the disengagement of the associated ratchet teeth.
• the electrical switchgear support described here can be used to mount one or more switchgear mechanisms (simultaneously). It also authorizes the horizontal or vertical mounting of one or more mechanisms in order to guarantee a position of the earth pin of the switchgear mechanisms always upwards.
• the frame of the electrical equipment support comprises an outer border and interior branches which will delimit several openings for accommodating the equipment mechanisms. Each reception opening is then bordered by the four branches as described above and which will allow the assembly and disassembly from the front of a basket which will house the fitting mechanism.
