• Tray 16 can here be positioned on carriage 76.
• the carriage 76 comprises at the front, at each corner, a roller 80 which is intended to roll against the rear face of the associated door 74, during the opening and closing of the doors 74.
• the plate 38 is equipped at the front with two actuating arms 82 which are capable of causing the opening of the doors 74 during an opening phase.
• the actuating arms 82 are here pivotally mounted on the plate 38 and they are actuated by lugs 83 positioned under the carriage 76 so that the sliding of the carriage 76 towards the open position causes the pivoting of the actuating arms 82 towards the outside, towards the doors 74 in the direction of their opening.
• the actuating arms 82 comprise at each end a right-angled portion 85 provided at its free end with a pad 87 which bears against the rear of the associated door 74.
• the carriage 76 advantageously comprises members for elastic connection with the doors 74. These elastic connection members can be hooked to the rear of the doors 74 and on the carriage 76 so that, when the carriage 76 slides backwards, c ie during a closing phase, he pulls on the doors 74 to return them to their respective closed positions.
• the elastic connecting members can also be hooked onto the actuating arms 82.
• the operation of the motorization assembly 32 according to the second embodiment is similar to that of the first embodiment.
• the user triggers the opening of the cabinet by means of the control interface 72.
• the electric motor 62 is powered so that the actuator 34 causes the longitudinal displacement of the carriage 76 from its closed position, or stored position, illustrated by figure 8, towards its open position illustrated by figure 9.
• the carriage 76 pushes the doors 74 by means of the rollers 80 and the actuating arms 82, pivoting the doors 74 around their hinges outwards.
• the user triggers the closing of the cabinet 10 by means of the control interface 72.
• the electric motor 62 is powered so that the actuator 34 causes the longitudinal displacement of the carriage 76 from its position opening to its closed position.
• the electromagnet 54 is energized which allows the pallet 50 to hook onto the carriage 76 and pull it rearwards.
• the carriage 76 drives the doors 74 towards their respective closed positions thanks to the elastic connection members 84.
• the carriage 76 is equipped with weight sensors 86 which are connected to the control unit 60. They make it possible to regularly measure the weight of the elements loaded in the tray 16 and to provide this information to the control interface 72.
• the motorization assembly 32 allows the cabinet 10 to operate manually, without electricity, when the actuator 34 is not activated.
• the control method can cause a disengagement of the motorization assembly 32 when an obstacle is detected on the path of the drawer 14 or of the carriage 76.
• the drawer 14 or the carriage 76 are automatically controlled by the actuator 34 to return to the rest position, or closed position.
