Description

Opening / closing device comprising at least one door leaf and

  actuating means acting on return means causing said leaf to move.

  The invention relates to the field of opening / closing devices.

  More specifically, the invention relates to the opening / closing means using a leaf or several leaves which it is desired to remotely trigger the displacement.

  In the field of the invention, there are known systems for opening or closing a leaf or several leaves using motorization means, the opening or closing being controlled by a transmitter held by a user and communicating with a fixed receiver which transmits a control signal to the motorization means.

  This technique is commonly used, and is particularly applied to the opening / closing of gates of individual houses or others.

  Conventionally, the motorized opening / closing systems applied to the gates comprise electric actuators for driving the leaves of the gate between their two extreme positions.

  According to this technique, the user is provided with a remote control by means of which it can trigger the actuation of the cylinders which then causes the opening or closing of the leaves of the gate.

  It is therefore understood that such a technique allows the user to control the opening or closing of his gate without having to get off his vehicle.

  The use of these motorized kits using electric cylinders gives the most often satisfaction, but nevertheless has several disadvantages.

  In the first place, these cylinders provide the portal a particularly unsightly appearance, this despite attempts to reduce the size of the cylinders in question.

  However, some portals are said to have a style or have a relatively elaborate design, such portals suffering from the aesthetic point of view of their association with cylinders.

  This disadvantage in terms of aesthetics, combined with the significant size of the cylinders, reduces the scope of possible applications. For example, it is difficult to report such jacks on window shutters.

  In addition, the pivoting of the doors of the gate can be performed only under the action of the cylinders. In other words, the cylinders used, not being disengageable, are by default in engagement, which prevents the manual movement of the leaves, except to deploy relatively large efforts.

  This therefore usually requires to provide, next to the gate, a non-motorized gate to allow entry or exit free people who do not have the portal control means.

  However, such a gate is in itself an additional cost item. In addition, there is not always enough room for the installation of such a gate.

  In addition, in case of failure of the cylinders, it is no longer possible or almost to move the gate leaves.

  Another disadvantage of current engine kits incorporating electric cylinders is their relatively high cost. It is indeed common that such kits represent a greater investment than the portal itself.

  Note that this technique is not exclusively reserved for gates, and can of course be transposed for example to garage doors using one or more leaves.

  However, for the automatic opening / closing of garages, it is more generally used one of the following doors: sectional door, consisting of several sections hinged together allowing the door to take a curved shape to be moved along. curvilinear rails; tilting door, moved in a curvilinear translation between a vertical position and a horizontal position, or vice versa.

  These solutions appear clearly reserved for building doors, and are therefore not suitable for all types of applications. For example, such solutions are incompatible in the field of portals.

  The invention particularly aims to overcome the disadvantages of the prior art.

  More specifically, the invention aims to provide a device for opening / closing leaf including motorization means that allow to consider new configurations in terms of ergonomics and / or aesthetics and / or features.

  In this sense, one of the objectives of the invention is to provide such a motorized opening / closing device which can be associated with any type of leaf in a discrete or even hidden manner.

  The invention also aims to provide such a device whose opening or closing can be triggered and / or obtained both through a manual operation directly on the device that by issuing a specific control signal.

  The invention also aims to provide such a device that can be easily adapted to many applications, whether in terms of building openings or openings in external perimeters.

  Another object of the invention is to provide such a device that can be manufactured easily and inexpensively.

  The invention also aims to provide such a device that is simple in design, easy to implement and install.

  These objectives, as well as others which will appear later, are achieved thanks to the invention which has for object an opening / closing device comprising at least one mobile leaf in rotation about an axis between at least two positions extremes, an open position and a closed position, and means for actuating said leaf or said leaves, characterized in that it comprises means for retaining said leaf or said leaves, movable between a retaining position and a release position of said leaf or said leaves, said actuating means acting essentially when said leaf is placed in one of the extreme positions, or in the vicinity thereof, on return means so that they tend to move said leaf to the other extreme position when said retaining means are in the release position of said leaf.

  The invention therefore proposes a fundamentally new approach to the motorization of the opening / closing devices.

  Indeed, the actuating means are not active during the phase of movement of the leaves. On the contrary, they intervene essentially when the displacement is finished, this in order to prepare the next displacement.

  The return means are thus tensioned and ready to cause the leaves to move (which therefore occurs independently of any action of the actuating means during the movement), this displacement occurring only when the retaining means pass into a position of release of the corresponding leaf.

  The principle of the invention therefore allows to consider a completely new type of operation, as will appear more clearly later.

  According to a preferred solution, said return means comprise at least one torsion element extending at least partially along said axis or in the vicinity thereof, said torsion element being coupled to said leaf, said actuating means being coupled to said element torsible and being capable of causing the torsion of said torsion element when said leaf is placed in one of the extreme positions so as to generate a restoring force on said leaf tending to move it towards the other extreme position In this way, the motor element causing the movement of the leaf is the torsion element which extends at the axis of rotation of the leaf.

  It is therefore understood that such an element can be associated in a much more discreet way to a leaf, compared to the electric cylinders of the motorization devices of the prior art.

  The motorization device according to the invention can therefore be associated with many types of opening / closing without degrading their aesthetics or that of their immediate environment.

  It is therefore possible to envisage applying the device according to the invention to gates, garage doors, but also to shutters or to any other type of casement opening.

  According to an advantageous solution, the device comprises at least one sensor for detecting said extreme position in which said actuating means are capable of acting on said return means, said detection sensor being connected to said actuating means so as to trigger these when said sensor detects said leaf.

  Thus, the activation of the actuating means is performed automatically after each movement of the leaf.

  Preferably, the device comprises a detection sensor for each end position, said actuating means being capable of being triggered by each of said sensors, the device comprising inverter means provided for inverting the restoring force exerted on said leaf by an extreme position with respect to the restoring force exerted on the leaf in the other extreme position.

  According to this arrangement, the same actuating means can act for the two extreme positions of the leaf, which tends to facilitate the installation of the device and to limit the cost.

  Advantageously, said actuating means comprise at least one electric motor connected to a power supply circuit in which said detection sensors act back and forth.

  An electric power supply circuit is thus implemented which is of current design and inexpensive to produce.

  Advantageously, the device comprises a movable element carried by said leaf intended to come into contact with said detection sensor or sensors.

  This gives an actuator (the mobile element) of mechanical type ensuring high reliability, insofar as it is subject to the position of the leaf and where it provides mechanical contact with the corresponding detector when the leaf is in one extreme positions.

  Advantageously, said inverter means act on the power supply of said one or more motors.

  Preferably, said inverter means comprise at least one fixed element intended to be actuated by said movable element during the rotation of said leaf between said extreme positions.

  In this way, the mobile element has a dual function: that of contacting the sensors to trigger the motor at each end position, and that of inverting the motor power at each movement between the extreme positions.

  According to an advantageous solution, the device comprises means for stopping said actuating means, said stop means being carried by said torsion element and being intended to act on the detection sensor having triggered said actuating means.

  In this way, it is possible to implement a relatively simple design engine, and in particular not disengageable. This therefore contributes to limiting the cost of the device.

  According to an advantageous variant, said torsion element is a flexible element.

  It is thus possible to move the drive means of the torsion element towards a discrete zone in the immediate environment of the leaf. This allows in some cases to avoid embedding the drive means in a wall or burial.

  According to a preferred embodiment, said retaining means are capable of passing from a holding position of said leaf to a release position of said leaf either under the effect of a manual action or under the effect of an electrical signal. remotely triggerable.

  Thanks to the principle of the invention, the opening or closing of the leaf can be obtained both by a person holding a specific control means (such as a remote control) than by a person who does not hold.

  Indeed, in one of the extreme positions, the return means tending to move the leaf towards the other extreme positions are systematically tense. It is therefore sufficient to place the retaining means in the release position as will be explained in more detail later, to allow the movement of the leaf which then operates freely.

  Also, insofar as the retaining means are designed to be operated manually or on specific order, the opening and closing of the leaf can be performed by anyone.

  In addition, in the event of failure of the actuating device, it is always possible to move the leaf, unlike the motorization device implementing actuators according to the prior art.

  Other characteristics and advantages of the invention will emerge more clearly on reading the following description of a preferred embodiment of the invention, and of one of its variants, given by way of illustrative and non-illustrative example. and in the accompanying drawings in which: Figure 1 is a front view of a gate leaf equipped with a device according to the invention; Figure 2 is a detailed view of the retaining means associated with a gate leaf equipped with a device according to the invention; Figure 3 is a detail view of the device illustrated in Figure 1; Figure 4 is a view of an alternative embodiment of a device according to the invention; Figure 5 is a schematic representation of an electrical circuit implemented in a device according to the invention; Figure 6 is a schematic bottom view of a device according to the invention.

  As already mentioned above, the principle of the invention consists in associating with a mobile leaf in rotation between two extreme positions, leaf retaining means and actuating means acting essentially when the leaf is retained by the retaining means. , so as to tension the return means which tend to move the leaf when it is released from the retaining means.

  Figure 1 illustrates a preferred embodiment of the invention applied to a gate leaf 1.

  As it appears, the leaf 1 is rotatably mounted about an axis xx ', the return means according to the invention being constituted by a torsion bar 2 secured by one of its ends to leaf 1 and coupled by the other of its ends to a motor 3.

  According to the present embodiment, the motor 3 and the associated electrical means are placed in a cavity made in the ground.

  In addition, retaining means 4 are provided to cooperate with a housing 11 provided for this purpose in the leaf 1 to hold the latter in each of these extreme positions (open leaf and closed leaf).

  Referring to Figure 3, the device comprises a movable member 5 constituted by a rod carried by the leaf 1 and intended to come alternately in contact with a sensor 6a and a sensor 6b placed in correspondence with the extreme positions of the leaf 1.

  This contact with the sensors 6a and 6b is established via a termination 51 carried by a rod 52 forming a right angle with the rod 5.

  In addition, the device comprises an inverter 7 whose function will be explained later.

  It is noted that, according to the present embodiment, the leaf is mounted on bearings 8 so as to limit the friction exerted on the leaf during the rotation thereof, in order to limit the torsional force to produce on the torsion bar 2 by the engine 3 while allowing a complete movement of the leaf between these two extreme positions.

  FIG. 5 illustrates an electric circuit implemented in a device according to the invention.

  As shown, the sensors 6a and 6b are reciprocated in the motor supply circuit 3.

  Furthermore, the inverter 7 consists of a toggle system for reversing the power supply of the motor 3.

  The operation of the device according to the invention will now be explained with reference to FIG.

  When the leaf is moved to one of its extreme positions, the leaf 1 is held in position by the retaining means 4.

  At the same time (or with a slight offset), the rod 52 is moved along the arrow F1 simultaneously with the leaf and brings the termination 51 into contact with one of the sensors, in this case the sensor 6a in FIG.

  This contact closes the supply circuit of the motor 3 which rotates and drives by any appropriate means (for example by a worm system) the torsion bar 2 so that the latter can exert on the leaf a return force tending to bring it back to the other extreme position.

  The stopping of the motor is controlled by a stop rod 9 carried by the torsion bar 2, this rod being moved according to the arrow F2 corresponding to the direction of rotation imposed by the motor 3 to the torsion bar 2 in the illustrated position FIG. 6. The engine is thus stopped when the stop rod 9 comes into contact with the sensor 6b which opens the motor supply circuit 3.

  Note that the rod 9 as shown extends at right angles to the rod 52. However, it may have another configuration depending on the torsion angle that is desired to exert on the torsion bar.

  Note also that the dimensions of the termination 51 can be adapted as necessary so as to cause a slight contact before the leaf occupies its extreme position. Thus, one begins to actuate the torsion bar before the leaf reaches the retaining means, which causes a braking of the leaf and avoids too much impact of it against the retaining means.

  When the retaining means release the leaf, the torsion bar 2 exerts a restoring force on the leaf which can then rotate freely.

  When the leaf is turned, the end 51 carried by the rod 52 actuates the inverter 7 (of course placed on the path of the termination 51), which inverts the future power supply of the motor 3 (the sensors 6a and 6b having remained in a position that the supply circuit is open).

  The rotation of the leaf then continues until the leaf reaches its other extreme position in which it is retained by the retaining means 4.

  The actuator 51 triggers the motor 3 by contacting the sensor 6b, the bar is set in torsion (with a direction of rotation opposite to that of the other extreme position thanks to the action of the inverter 7), then the motor is stopped by the stop rod 9 when it comes into contact with the sensor 6a.

  Referring to Figure 2, there are provided retaining means 4 for cooperating with a housing 11 provided in the leaf 1, so that the release of the leaf 1 relative to the retaining means can be obtained either through an action manually, either by means of an electric control.

  This is obtained by providing, on the one hand, that the retaining means 4 are carried by a pedal 41 that is elastically deformable, making it possible to manually release the means for retaining the housing 11.

  On the other hand, this housing 11 comprises a keeper 111 pivotally mounted in the leaf, and movable between a retaining position (in solid lines) and a release position (in dashed lines).

  Such a striker 111 is actuated electrically according to an implementation known to those skilled in the art, and controlled by a remote control system.

  According to an alternative embodiment illustrated in FIG. 4, the leaf 1 is mounted on hinges 10 and the device according to the invention is mounted at the top of the leaf being supported by the element 101 carrying the hinges 10.

  Note that according to another embodiment possible, the torsion bar is made of a flexible material, which allows to deport the actuating means in a position other than in the extension of the axis of rotation of the leaf.

  Moreover, the actuating means may comprise a simple 12V motor, a battery that may be suitable for powering it.

  The device according to the invention may be proposed in the form of a ready-to-assemble assembly comprising: an electrical circuit as described above, including in particular the extreme position sensors and an inverter; a motor; a battery; a torsion bar; an electric strike; a receiver of a signal to be associated with the electric strike and a corresponding remote control. 25
