Folding support device for smart doors

Hinged support device for intelligent doors, which can be housed inside a door leaf (A), comprising:

• a folding element (1) that can rotate between an inactive position, in which the folding element (1) is contained within the door leaf (A), and an active position, in which the folding element (1) is folded out at a right angle to the inactive position,
• a fastening element (2) which is fixed to the inside of the door leaf (A) and to which the folding element (1) is hinged at a first hinge point (3), and
• driving means (4), housed inside the door leaf (A), which act on the folding element (1) to cause it to rotate,
• characterised by the fact that
• the driving means (4) comprise a rod (5) which can move linearly between two extreme positions defining the inactive and active positions, wherein the free end of the rod (5) is connected to a first end of a first transmission element (6), the second end of which is hinged at a second hinge point (7), with a first end of a second transmission element (8) whose second end is hinged, at a third hinge point (9), to a middle section of the folding element (1), where the linear movement of the second hinge point (7) is limited by a first guide (10) comprising the fastening element (2) whose direction is parallel to the direction of movement of the rod (5) of the driving means (4).
