    [0001] The invention relates to the field of opening drive systems. BACKGROUND OF THE INVENTION To move an opening such as a door, a window, a gate, a flap, a hatch, a flap, a partition, or to wind a fabric, a net, a protective film, a tarpaulin between a closed position and an open position of the opening, there is a large number of drive systems. For example the document US6382005 B1 describes a drive system of an opening, in this case a garage door. This system comprises an electric motor for driving the opening, position sensors for sensing the displacement of the opening relative to a frame of the opening and thus to determine stopping positions of the engine. These position sensors of the opening must be adjusted to ensure a correspondence between the position sensed by the sensor and the position actually adopted by the opening. Improper adjustment of the drive system can lead to damaging the sash, if for example the motor forces the sash when it is already in an end position and it bears against a stop. Similarly, a wrong setting can lead to a sash detection in the closed position when in fact, the sash is always in an intermediate position, between its open and closed positions. The setting of the sash drive system is particularly difficult for the user. OBJECT OF THE INVENTION An object of the present invention is to provide a control system of an engine which has features facilitating its adjustment by a user and a repeatability of the closed and open positions. SUMMARY OF THE INVENTION To this end, it is proposed according to the invention, a drive system of an opening comprising: a motor driving a shaft for controlling the movement of an opening such as a door or an entrance ; at least a first motor control means adapted to selectively adopt an electrical power supply configuration of the motor and a non-power supply configuration of the motor. The drive system according to the invention is essentially characterized in that it comprises: a shaft threaded over at least a portion of its length, this threaded shaft being rotatably mounted along a first axis of rotation and being adapted to be rotated by the motor along this first axis of rotation; at least one first nut cooperating with said threaded shaft so as to form a screw-nut connection between the threaded shaft and the first nut; at least first indexing means arranged to engage selectively with said first nut and when engaged with this first nut, these first indexing means prohibit the rotation of said first nut with respect to these means; indexing while permitting the axial displacement of said first nut along said threaded shaft; said at least one first motor control means is arranged to be in its feed configuration when the first nut is positioned along a first axial portion of the threaded shaft and to be in its configuration. non-feeding when this first nut is positioned along a second axial portion of the threaded shaft which is distinct from said first axial portion. When the first indexing means are engaged with said first nut, they then prohibit the rotation of the nut and thus, if the threaded shaft is rotated by the motor, this first nut moves along the length of the nut. threaded shaft. This displacement of the first nut moves it from the first axial portion towards the second axial portion of the threaded shaft, or conversely according to the direction of rotation of the threaded shaft relative to the first nut. The first motor control means is in the feed configuration when the first nut is along the first axial portion of the threaded shaft and is in the non-feed configuration when the first nut is along the second axial portion of this threaded shaft.
    [0002] Thanks to the screw-nut connection between the threaded shaft and the first nut, it is certain that at any given rotation of the threaded shaft, there corresponds a proportional axial displacement of the nut, which limits the risk of have a phase shift between the rotation of the shaft driven by the motor and the axial position of the first nut. Thus, each closed position and each open position memorized by the drive system according to the invention is stable over time and can be repeated with each cycle of operation of the drive system.
    [0003] When the first indexing means are engaged vis-à-vis the first nut, they then prohibit the rotation of the first nut relative to the first indexing means which forces the first nut to move along the first threaded shaft in response to rotating the threaded shaft. Conversely, when the first indexing means are disengaged with respect to the first nut, the rotation of the first nut relative to the first indexing means is then allowed and the first nut can then rotate with the threaded shaft. when the latter is rotated. Thus, when the first indexing means are disengaged with respect to the first nut, the rotation of the threaded shaft causes the first nut to rotate without this nut moving along the threaded shaft. .
    [0004] 3037607 Thus, when the user wants to define a first position of the engine in which he wishes that there is no possible power supply of the engine via the first engine control means, it suffices for successively: - disengage the first indexing means vis-à-vis the first nut; then - operating the engine until it reaches a first desired position of the engine which corresponds to a given position of the opening; then - screwing the first nut along the threaded shaft until it is along the second axial portion of the threaded shaft, the first motor control means then passes into its feed; then - engaging the first non-indexing configuration means with the first nut to cause the first nut to move along the threaded shaft in response to a rotation of the threaded shaft.
    [0005] Thanks to the sash drive system according to the invention, the user can simply set and memorize the first position of the engine in which this motor can not be powered via the first control means. For this, it suffices to move the first nut along the threaded shaft while the first indexing means are disengaged from the first nut, then to re-engage the first nut. Since the first position of the engine corresponds to a first given position of the opening leaf, it suffices for the user to manually control the motor to position the opening in its first given position, then to cut off the power supply of the motor and to memorize the position reached by the engine. According to a preferred embodiment of the engine control system according to the invention, this system further comprises: a second nut cooperating with the threaded shaft so as to form a screw-nut connection between the threaded shaft; and this second nut; and at least second indexing means arranged to engage selectively with said second nut and when engaged with this second nut, these second indexing means prohibit the rotation of said second nut relative to these second means. indexing while permitting the axial displacement of said second nut along said threaded shaft; at least one second motor control means adapted to selectively adopt an electrical power supply configuration of the motor and a non-power supply configuration of the motor; and said at least one second engine control means is arranged to be in its feed configuration when the second nut is positioned along the first axial portion of the threaded shaft and to be in its drive configuration. non-feed 20 when the second nut is positioned along a third axial portion of the threaded shaft, the first axial portion being between the second and third axial portions of the threaded shaft. With this embodiment the motor can be powered via the first control means or via the second control means. Thus, the first control means and the motor can be arranged so that when the first control means is in its power supply configuration of the motor, then this motor moves in a first direction. Similarly, the second control means and the motor can be arranged so that when the second control means is in its power supply configuration of the motor, then this motor can be controlled to move in a second direction which is opposite to said first direction.
    [0006] As the second engine control means is arranged to be in its non-feed configuration when the second nut is positioned along a third axial portion of the threaded shaft, the drive system according to The invention makes it possible to define: a first position of the motor in which the motor can not be powered via the first control means, the motor then being able to be powered only via the second control means; and a second motor position, which is distinct from the first position of the motor, and in which the motor can not be powered via the second control means, the motor then being able to be powered only via the first control means . The adjustment of this second position of the motor is done in the same way as for the first position, with the difference that instead of engaging or disengaging the first indexing means with respect to the first bolt, the user engages or disengages the second indexing means vis-à-vis the second nut. When the second indexing means are engaged with said second nut, they then prohibit the rotation of the nut and thus, if the threaded shaft is rotated by the motor, this second nut then moves along the length of the nut. threaded shaft. The second engine control means is in the feed configuration when the second nut is along the first axial portion of the shaft. The second control means is in a non-supply configuration when the second nut is along the third axial portion of the shaft.
    [0007] When these second indexing means are engaged vis-à-vis the second nut, they then prohibit its rotation relative to the second indexing means which forces the second nut to move along the threaded shaft in response to the rotation of this tree.
    [0008] In contrast, when the second indexing means are disengaged, even if the threaded shaft is rotated the second nut, the second nut can remain fixed relative to this shaft and thus not move along this shaft threaded.
    [0009] When the first and second indexing means are disengaged with respect to the first and second nuts, the user can control the motor to move the sash to reach a desired end position. memorize, without the nuts moving along the shaft. There is therefore no risk that a disengaged nut comes to lock axially during this storage. The operator can thus freely maneuver the engine without worrying about the position of the nut (s) he has disengaged (s).
    [0010] When the user wants to define a second position of the engine in which he wishes that there is no possible engine power via the second motor control means, it is sufficient for successively: - disengage the second means indexing vis-à-vis the second nut; then - to operate the engine until it reaches the second desired position of the engine which corresponds to a given position of the opening; then - screw the second nut along the threaded shaft 30 until it is along the third axial portion of the threaded shaft which corresponds to the portion of the threaded shaft in which the second motor control means is in its non-power configuration; and then engaging the second indexing means with the second nut to cause this nut to move along the threaded shaft in response to rotation of this threaded shaft. According to an alternative embodiment of the above, the sash drive system (s) according to the invention: - comprises at least a second engine control means adapted to selectively adopt a power supply configuration of the engine and a non-power configuration of the engine; and said at least one second motor control means is arranged to be in its feed configuration when the first nut is positioned along the first axial portion of the threaded shaft and to be in its configuration. non-feed 15 when the first nut is positioned along a third axial portion of the threaded shaft, the first axial portion being between the first and second axial portions. According to this alternative a single nut is threaded onto the threaded shaft to move along the shaft and thereby control the configuration changes of the first and second control means as a function of its position along the threaded shaft. Here, when this first nut is deindexed vis-à-vis the first indexing means, the adjustment in position of the first nut can be done. For this, it is sufficient to translate this first nut along said threaded shaft by pivoting the first nut relative to this threaded shaft. In addition to this mode, to enable the amplitude of the first axial portion to be defined, it is possible for at least one of the engine control means to have a first position sensor of the first nut which is independent of the first threaded shaft and movable along this shaft threaded between several axial positions respectively indexable. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood on reading the following description of nonlimiting embodiments, with reference to the figures of the attached drawings in which: FIG. 1 illustrates a horticultural greenhouse provided with a motorized opening between open and closed positions via sash drive system according to the invention; FIG. 2 shows an external view of a casing of the sash drive system according to the invention, here the motor is integrated in the casing and an engine shaft extends through the casing for a part of the opening with which it is mechanically coupled via coupling means and secondly drive a threaded shaft of the drive system via a motion transmission; FIG. 3 is a diagrammatic front view of the sash drive system according to the invention; and FIG. 4 is a schematic sectional view A-A of the opening drive system of FIG. 3, this FIG. 4 illustrating the second nut indexing means. DETAILED DESCRIPTION OF THE INVENTION The invention relates to a drive system 1 of at least one opening 2 that can be used to drive one or more openings.
    [0011] FIG. 1 shows an assembly 0, in this case a horticultural greenhouse comprising: a drive system 1 according to any one of the embodiments of the invention; and - an opening 2 movable along a stroke of the opening 35 extending between first and second positions of the opening (open and closed positions), this opening 2 3037607 10 being driven along its stroke via a shaft 3 driven by the engine. As indicated previously and illustrated in FIGS. 2 and 3, the opening drive system 1 comprises: a motor M driving the shaft 3 to control the movement of the opening 2 such as a door or a door; portal; first motor control means 4 adapted to selectively adopt an electrical power supply configuration of the motor and a non-power supply configuration of the motor; a second control means 8 of the motor M adapted to selectively adopt a power supply configuration of the motor M and a non-power supply configuration of the motor M; a shaft 5 threaded over at least a portion of its length, this shaft being mounted for rotation along a first axis X-X of rotation and being adapted to be rotated by the motor M along this first axis of rotation X-X; first and second nuts 6a, 6b each cooperating with the threaded shaft 5 to each form a screw-nut connection with the shaft 5; first indexing means 7a arranged to be selectively engaged with said first nut 6a and when they are engaged with this first nut 6a, these first indexing means 7a prohibit the rotation of said first nut 6a with respect to these means indexing 7a while permitting the axial displacement 30 of said first nut 6a along said threaded shaft 5; second indexing means 7b arranged to be selectively engaged with said second nut 6b and when engaged with this second nut 6b, these second indexing means 7b prohibit the rotation of said second nut 6b with respect to these second indexing means 7b while permitting axial displacement 3037607 11 of said second nut 6b along said threaded shaft 5. Said at least one first control means 4 of the motor is arranged to be in its feed configuration when the first nut 6a is positioned along a first axial portion P1 of the threaded shaft and to be in its non-feed configuration when this first nut 6a is positioned along a second axial portion P2 of the threaded shaft 5 which is distinct from said first axial portion Pl.
    [0012] Said second control means 8 of the motor M is arranged to be in its feed configuration when the second nut 6b is positioned along the first axial portion P1 of the threaded shaft and to be in its configuration of no. supply when this second nut 6b is positioned along a third axial portion P3 of the threaded shaft 5, the first axial portion P1 being between the second P2 and third P3 axial portions of the threaded shaft 5. The shaft 3 of the motor M used to drive the opening 20 is also coupled to the threaded shaft 5 via a motion transmission to drive it with a fixed drive ratio such that any given displacement of the engine corresponds to a given drive of the shaft 5. Here, this transmission of movement is achieved by a driving pinion 25 carried by the shaft 3 of the motor M, by a driven pinion carried by the threaded shaft 5 and by a chain which connects these pinions m and between them. Any other transmission of motion between the motor M and the threaded shaft could be used to implement the invention. For example, this transmission of motion could be by pulleys / belt OR by a cascade of gears OR by a bead with conical torques. The sash drive system 1 according to the invention allows an operator to memorize in the system, mechanically and without tools, the limit positions of the engine M in which he wishes that the engine 3037607 12 can no longer move towards a given meaning. When one of these limit positions is reached, that is to say when the first nut 6a passes into the second portion P2 or when the second nut 6b passes into the third portion P3, the motor M can not then be controlled only in a direction of movement to move it away from this limit position, that is to say, necessarily a direction allowing the return of the nuts to the first portion P1 which is placed between the threaded shaft portions P2 and P3 . The system 1 according to the invention limits the need to use end stops to measure directly on the opening reaching a limit position.
    [0013] For the understanding of the invention, the term power supply configuration of the motor, when applied to the first control means 4, indicates that the first control means 4 allows the power supply of the motor, which does not imply that the motor is necessarily fed. Likewise, the term power supply configuration of the motor, when applied to the second control means 8, indicates that this second control means 8 opposes the power supply of the motor, which does not imply that the engine is necessarily not powered. A motor can indeed be powered if only one of the two control means 4 and 8 is in the power configuration and this even if the other of these control means 4 or 8 is in the non-power configuration.
    [0014] The wiring of the motor and the first and second control means is such that: - when the first control means 4 is in a non-supply configuration, it then opposes a power supply of the motor which would induce a rotation of the motor towards a first direction, in this case the first direction is that which forces the first nut to go from the first portion P1 of the shaft 5 to the second portion P2; and when the second control means 8 is in a non-supply configuration, it then opposes a power supply to the motor which would induce a rotation of the motor towards a second direction opposite to said first direction, in this case the second direction is the one that forces the second nut 6b to go from the first portion P1 of the shaft 5 to its third portion P3 of the shaft 5. The first nut 6a is a piece of revolution having a proper axis of symmetry which is confused with the first axis of rotation of said threaded shaft 5. This first nut has notches at its periphery which, in a particular case, are external grooves each extending parallel to the axis of symmetry of the first nut 6a. The first indexing means 7a have a movable index 70a between: an indexing position in which this index 70a can penetrate into one of the notches or grooves of said first nut (6a) in order to engage said first nut 6a and thus prohibit its rotation relative to these first indexing means 7a; and a release position in which this index 70a is spaced from the notches or grooves of said first nut 6a. The second nut 6b is a part of revolution 30 having an axis of symmetry of its own and which coincides with said first axis XX of rotation of said threaded shaft 5. This second nut has notches at its periphery which may be external grooves . The second indexing means 7b have a movable index 70b between: an indexing position of the second nut 6b in which this index 70b can penetrate into one of the notches or grooves of said second nut in order to engage said second nut and thus prohibit the rotation of said second nut 6b with respect to these second indexing means 7b; and - a release position of the second nut 6b wherein the index 70b is spaced from the notches or splines of said second nut. In FIG. 3, the first and second indexing means 7a 7b are shown in broken lines while they are in their respective release positions with their indexes 70a, 70b apart from the corresponding nuts 6a and 6b. In this figure 3, the first and second indexing means 7a 7b shown in solid lines are in their respective indexing positions, the indexes 70a and 70b are respectively engaged with the respective nuts 6a, 6b. For each of the respective first and second nuts, the external notches or grooves 12 are respectively formed and evenly distributed around the nut. This regular distribution of notches or grooves 12 allows to have an adjustment angle in the nut position which is the regular angle between two grooves of the nut. In the example of Figure 4, the nut has a number of male or female notches which allows a finer adjustment as the number of notches is important. In this case, here there are 12 notches which are here splines regularly distributed around the periphery of the nut which allows adjustment by twelfth turn of the nut. This number is chosen according to the fineness of adjustment desired for the positioning of the nut. For example, each nut can have 22 splines which allows a very precise angular adjustment of the indexing position of the nut 35 thus accurately memorizing the associated end positions of the motor M.
    [0015] The first indexing means 7a are slidably mounted along a guide axis YY parallel to said first axis of rotation XX of said threaded shaft 5. In the same manner, the second indexing means 7b are slidably mounted along the axis guide YY parallel to said first axis of rotation XX of said threaded shaft. Thus these first and second indexing means 7a, 7b are movable as carriages along the Y10 axis Y. When the first indexing means 7a index the first nut 6a to rotate, any axial displacement of the first nut 6a along the threaded shaft 5 also causes the axial displacement of the first indexing means 7a. For this, the first nut has an annular groove in which is positioned a finger-shaped portion of the first indexing means 7a when indexing the first nut 6a. Similarly, when the second indexing means 7b index the second rotating nut 6b, any axial displacement of the second nut 6b along the threaded shaft 5 also causes the axial displacement of the second indexing means 7b. For this, the second nut 6b has an annular groove in which is positioned a finger-shaped portion of the second indexing means 7b when they index the second nut 6b. As illustrated in particular in Figures 2 and 3, each first and second indexing means 7a, 7b and 30 each first and second nut 6a, 6b is disposed within a same housing 9. This housing protects the screw connections nut, the connector 15 and the control means 4 and 8. Ideally, this housing 9, when closed is sealed, 35 which allows the drive system 1 of the invention to withstand moisture conditions. Note that the connector 15 is part of the system wiring and includes a multi-pin plug and a complementary socket for ease of system installation and replacement 1.
    [0016] The first indexing means 7a comprise a manual actuation zone 72a, manually actuable, preferably without tools, by an operator to control the disengagement of the first indexing means 7a vis-à-vis said first nut 6a.
    [0017] In the same way as for the first indexing means 7a, the second indexing means 7b comprise a manual actuating zone 72b, manually operable, preferably without tools, by an operator to control the disengagement of the second means. indexing 7b vis-à-vis said second nut 6b. It is noted that the manual actuation zones 72a and 72b are accessible to be handled manually and without tools by the operator. As can be seen in FIG. 2, this access to the manual actuation zones 72a, 72b is via an opening 10 of the housing selectively closed off by a not shown hatch. A slider 11 has a lumen through which the manual operating zones 72a, 72b pass to prevent the operator from forcing the manual actuation zones 72a, 72b beyond actuating limit positions. This strip 11 also forms a cover to limit the manual access area of the operator and thus limit the risk that it does not hurt or damage a masked element placed inside the housing.
    [0018] The first indexing means 7a comprise an elastic return means 71a of said index 70a towards its indexing position. In this case, as can be seen in FIG. 3, this elastic return means 71a is a spring that bears against a rear part of the index 70a. In the same way as for the first indexing means 7a, the second indexing means 7b comprise an elastic return means 71b, in this case a spring which bears against a rear part of the index 70b. , to recall this index 70b 5 of said second indexing means 7b to its indexing position. As seen in Figure 3, the first control means 4 of the motor comprises first and second switches 4a, 4b. The first switch 4a is actuated by the first nut 6a when it is opposite a first axial position placed in the second axial portion P2 of the threaded shaft 5. The second of these switches 4b is actuated by the first nut 6a when it is facing a second axial position 15 placed in the second axial portion P2 of the threaded shaft. This second axial position is offset from the first axial position and further from the first portion P1 than is the first position of the first nut.
    [0019] According to this preferred embodiment, the first and second switches 4a, 4b of the first motor control means are connected in series so that in case of malfunction of one of these switches, the other detects the passage of said first nut. in the second axial portion of the shaft. Similar to what has just been described for the first control means 4, the second control means 8 of the motor M comprises first and second switches 8a, 8b. This first switch 8a is actuated by the second nut 6b when it is facing a first axial position, specific to this second nut, placed in the third axial portion P3 of the threaded shaft 5. The second of these Switches 8b is actuated by the second nut 6b when it is opposite a second axial position, which is specific to this second nut 6b and placed in the third axial portion P3 of the threaded shaft. This second axial position of the second nut is offset from the first axial position of the second nut and further from the first portion P1 than is the first position of the second nut.
    [0020] According to this preferred embodiment, the first and second switches 8a, 8b of the second control means 8 of the motor M are connected in series so that in case of malfunction of one of these switches 8a, 8b, the other detects passing said first nut into the second axial portion of the shaft. Although it has been described that the first and second control means 4 and 8 may comprise switches, they may also include nut proximity sensors with or without contact.
    [0021] Thanks to the manual operating zones 72a and 72b and the knurled nuts 6a and 6b, the drive system according to the invention can be adjusted manually, without any tools, which greatly facilitates the operations of the operator while he to memorize precise 20 positions of motor end M.
