Thus, an apparatus according to the present invention does not require specific skills for installation, also, the high voltage electrical components is enclosed in the second container 25 therefore it does not expose the installer to risks and does not require the intervention of qualified operators.
The transformer 24 is advantageously connected to a socket / plug which defines the second connector 26 and is placed on the external of the second container 25 to be connected to the electricity grid and has also a low voltage electrical connection 25a, to connect to the primary group 16 to power it.

The beam 12 is preferably configured to support the first container 21 in its own central portion with respect to its longitudinal direction C of development.
More particularly, the beam 12 advantageously comprises a base section 12a to be fixed to the wall 13 and a support 12b which can be fixed to the base section 12a and configured to mate with the first container 21.
Advantageously, the support 12b includes threaded pins 120 and the first container 21 comprises through holes 210 adapted to receive in insertion the threaded pins 120 to fix, by means of nuts screwed onto the threaded pins, the primary group 16 to the beam 12.
To avoid that an inexperienced or careless operator from damaging the primary group 16 by excessively tightening the nuts, advantageously inside of the through holes 210 are inserted cylindrical elements 211 having a length less than that of the hole and such that they limit the tightening of the nuts so to avoid clamping tension that may damage the first container 21.
The geared motor 33, when the door 11 is of two leaves 11 a and 11 b, preferably comprises two pulleys, mutually coaxial, or a single pulley adapted to be coupled to both sides of the dragging elements of a leaf 11 a or 11 b of the door 11.
The actuating apparatus 10 in this case preferably comprises a pair of timing pulleys for the dragging element, fixed to the beam 12 on opposite sides of first container 21.

In particular, preferably the apparatus 10 comprises a clamping element 35 adapted to be fixed to a bar 36, which slides along the beam 12 and can be fixed to the door to sustain a leaf 11 a or 11 b.
The clamping element 35 preferably comprises a seat in which the two extremes of a dragging element is forced to close the ring and at the same time to connect it to the bar 36 so as to allow the dragging of the latter and the leaf.
When the door 11 is a leaf, the beam 12 is advantageously configured to support the first container 21 in a lateral portion, next to its first end, with respect to a longitudinal direction C of development.
In this case, the actuating apparatus comprises a single timing pulley for the dragging element, conventional per se and not illustrated, fixed to the beam 12 at the second end of the latter.
To facilitate the transportation and warehouse management of the components of the device 10, the beam 12, or more precisely the base section 12a, preferably consists in two pieces having the same profile and connected in an aligned manner with respect to the respective longitudinal directions of development, which in figure 1 coincide and are illustrated as the development direction C.
For structural simplicity and in order to simplify the installation and the management of components in stock, the pieces preferably are mutually connectable by means of the first container 21 or by means of a bracket also adapted to support the first container 21.
Advantageously, to limit the noise of the apparatus 10, elastic supports are anticipated, connecting the motor 17 to the first container 21.
Furthermore, to obtain a high safety of the apparatus, a kinematic mechanism 37 which can act on the electro-block 27 to prevent rotation of the pulley 34 is envisaged.
Such kinematic mechanism 37 can also be operated manually to lock or unlock the rotation of the pulley 34 and consequently the opening / closing of the door 11.
The kinematic mechanism 37 particularly is provided with a pivoting arm 39 which, by tilting, is coupled with a ring gear 40 coaxial and integral or fixed to the pulley 34.
Functionally, the kinematic mechanism 37 may be:

In a first configuration, exemplified in figure 16, in which the tilting arm 39 inserts between two teeth of the ring gear 40, preventing rotation of the pulley 34;
In a second configuration, exemplified in figure 15, in which the rocker arm 39 disengages the ring gear 40 and thus liberates the pulley 34 to rotate freely.

The electro-block 27 is provided with a small piston 27a adapted to actuate the kinematic mechanism 37 to make it pass from the second to the first configuration.
Preferably, the apparatus 10 includes a button 41, preferably envisaged on an exposed face, in use, of the first container 21; the button 41 is connected to the kinematic mechanism 37 to be able to operate the transition from the first to the second configuration.
To facilitate installation, the base section 12a is preferably constituted by two portions 200a and 200b and by a connecting element 200c provided with a slotted hole 201.
This solution is preferable when it is useful to reduce the overall dimensions during transportation, providing the base section mountable, for union of the two portions 200a and 200b by means of the connecting element 200c.
The two portions 200a and 200b each have one end preferably shaped to not obstruct the slotted hole 201 when they are assembled with the connecting element so as to allow the insertion of a screw 202 through the hole.
On assembly, preferably, the base section is mounted, assembled, pivoted to the wall by means of the screw 202, then it is leveled and, thus, fixed to the wall.
This construction is clearly very simple to implement.
In corresponding manner, the casing element 14 can constitute two longitudinal portions 141 and 142 corresponding to the two portions 200a and 200b, preferably in PVC.
Advantageously, the two longitudinal portions 141 and 142 are substantially C-shaped to be fixed to the pieces 200a and 200b so as to form tubular elements, opened below, on which the track trolleys 15 roll.
To avoid deformation of the longitudinal portions 141 and 142, advantageously the apparatus 10 comprises support elements 201 and 202, a first 201 of which is preferably fixed to or integral with the primary group 16, a second support 202 being fixed to a corresponding portion 200a or 200b in an intermediate position along the development of the latter.
The supports 201 and 202 are preferably shaped so as to maintain the form and the desired position of each longitudinal portion 141 or 142, in particular preventing twist, so as to reduce the material used to construct the latter with the advantage of lightness and simplicity of production of the device 10.
It is then observed how the present invention achieves the intended aim and purposes.
In particular, the actuating apparatus according to the present invention is easier to install, being sufficient to fix the beam to the wall and thus, fix the primary group and eventually the secondary group, electrically connecting this / these to the electricity grid, and eventually between them, and kinematically connects the leaves, and finally the assembly plans to close the beam with the casing element 14.
All this without having to assemble the electrical and electronic components directly on the beam as it happens for the traditional apparatuses.
Then, the actuating apparatus according to the present invention allows for a simple logistics of warehousing and distribution of the product and does not require specialized personnel for its assembly.
It is also more compact, in particular by envisaging for the beam to be assembled by the pieces.
The invention thus conceived is susceptible to numerous modifications and variants, all falling within the protective scope of the appended claims.
Moreover, all the details may be replaced with other technically equivalent elements.
In practice, the materials employed, as well as the forms and the dimensions, may be varied depending on the contingent requirements and state of the art.
Where the constructional characteristics and techniques mentioned in the following claims are followed by reference signs or numbers, such signs and reference numbers have been applied with the sole purpose of increasing the intelligibility of the claims and consequently, they do not constitute in any way limiting the interpretation of each element identified, purely by way of example, by such signs and reference numbers.
