Definitions

• the invention relates to motorized opening and closing devices for gates and more particularly to devices intended for sliding gates.
• Automated devices for opening and closing a sliding gate between two columns or other fixed structures are already known. These devices generally include a motor fixed to the ground which drives a toothed pinion. The pinion meshes with a rack fixed to a portal to drive the latter in translation.
• the gate also has wheels which allow it to move along the ground during opening and closing. To facilitate guiding the wheels, grooves can be provided on the ground between the two columns.
• These types of gates are generally equipped with a presence detector between the two columns which makes it possible to stop the movement of the gate if an object or a person is in its path. These detectors generally include an infrared emitter fixed on one of the columns and a receiver placed opposite the emitter on the other column and capable of detecting the light rays emitted by the emitter.
• a disadvantage of these systems is that they require the machining of a pinion and a rack whose length is at least equal to the distance over which the gate moves. The manufacture of these mechanical parts is therefore expensive. Another drawback is that the installation of the rack can be tricky, in particular on openwork gates. In addition, the motor must be fixed on sufficiently hard ground and at a height allowing the contact of the pinion and the rack. Generally, a concrete screed is made to consolidate the ground and adjust the height of the engine. Another disadvantage of these systems is that they require the installation of connections allowing the supply of the motor and the presence detector.
• the object of the invention is to overcome these drawbacks by proposing a motorized assembly for driving a sliding gate, characterized in that it comprises a motorized block and a support in which the block is mounted with play and can slide in a generally vertical direction, the motorized unit comprising a motor, at least one wheel driven by the motor and a battery for supplying the motor, the wheel being able to come into contact with the ground under the effect of the unit's own weight motorized.
• the motorized drive assembly has the advantage of being autonomous and of not requiring a material link with an external power supply. This characteristic allows very rapid installation of the opening and closing device.
• the motorized block being mounted with play in the support, it can tilt in the plane of the wheel (s). In this way, the block keeps most of the time at least one wheel in contact with the ground despite the irregularities thereof. This advantageously allows it to adapt to the surface of the ground and to overcome the irregularities encountered.
• the support is fixed to the sliding portal and the motorized unit is capable of coming into horizontal abutment on said support so as to tow the sliding portal,
• the motorized unit comprises projecting support elements by means of which it comes to bear on a wall of the support fixed on the sliding gate.
• the motorized unit comprises at least two wheels aligned in the direction of movement of the sliding gate. This characteristic makes it possible to increase the contact surface of the wheels with the ground and to multiply the torque allowing the assembly to tow the sliding gate.
• the block may include a transmission element and the motor is capable of driving at least two of the wheels in rotation via the transmission element. Since the motor drives two wheels, the block can tilt while keeping at least one drive wheel in contact with the ground. This characteristic makes it possible to ensure the drive of the gate despite the presence of elements of small dimensions being on its trajectory.
• the motorized drive assembly comprises means forming a contact engaging with external power supply means when the sliding gate is in an extreme position of its trajectory and causing the battery to be charged
• the motorized assembly d drive includes a solar panel connected to the battery
• the motorized drive assembly also comprises a control module capable of cutting off the power to the motor or of controlling the rotation of the motor in the opposite direction,
• the detection means are connected to the control module and the module is capable of cutting off the power to the motor when a presence is detected on the path of the sliding gate,
• the control module includes means for detecting a battery charging phase.

• FIG. 11 is a front sectional view of an example of supply means of the locking device.
• FIGS 1 and 2 are front and side views of a motorized block 100.
• This block 100 comprises a frame 1 consisting of a plate in the general shape of U in horizontal section.
• a horizontal sole 2 and a vertical plate 3 are fixed between the two wings of the chassis 1.
• the sole 2 supports an electric motor 4 (of the vehicle window motor type for example) as well as a battery 5 and an electronic card control 6.
• Two wheels 7 are mounted in cantilever on the vertical plate 3.
• the motor 4 rotates the two wheels 7 via a reducer 13 fixed to the vertical plate 3 by buttoning.
• the electronic control card 6 has four connections 7, 8, 9 and 10. This card 6 is connected to the battery 5 at connection 7.
• the power supply cable 11 of the motor 4 is connected to connection 8.
• the connections 9 and 10 are respectively connected to a presence detection cell and to end of stroke detection means not shown in FIGS. 1 and 2.
• Projecting support elements 12 are fixed to the wings of the U-shaped chassis 1 so as to come to bear on a fixing support 200 shown diagrammatically in FIG. 3, in which the motorized block 100 is inserted.
• These elements supports 12 are in the form of a half-cylinder slice made of polymer material (for example Delrin® or Teflon®), the support surface being constituted by the surface portion cylindrical.
• These elements 12 may have lateral chamfers making it possible to reduce their contact surface with the support 200 and to limit friction.
• the mounting support 200 shown in Figure 3 has a general U-shape in horizontal section with a bottom plate 14 and two wings 15. It has a length L2 slightly greater than the length L1 of the motorized unit 100 so as to allow the sliding but also a certain tilting of the motorized block 100 in the support 200. Preferably the length L2 is longer than the length L1 from l to 2%.
• FIGS. 4 to 6 represent bottom, front and top views of the motorized unit 100 of FIGS. 1 and 2 inserted in the fixing support 200 of FIG. 3.
• FIG. 5 also shows the motorized unit 100 inserted in the fixing support 200 such that they can be integrated into a device for opening and closing a sliding gate 17.
• the fixing support 200 is mounted integral with a portal 17 at one of its lower ends.
• the motorized unit 100 has been inserted into the U-shaped mounting support 200. In this way, the wheels 7 are in contact with the ground 18. When the wheels 7 are driven in rotation by the motor 4, the unit 100 moves on the ground 18 and the elements 12 come to bear on one of the wings 15 of the fixing support 200 situated in the direction of movement.
• the motorized unit 100 drives the portal 17 in translation via the fixing support 200.
• the block 100 includes two wheels 7 and is mounted in the fixing support 200 with play, it is free to tilt.
• the block 100 mostly retains its two wheels 7 in contact with the ground 18 despite the irregularities thereof. This characteristic guarantees good adhesion of the block 100 on the ground 18. Since the motor drives the two wheels 7 in rotation, the block 100 can tilt while keeping at least one drive wheel 7 in contact with the ground 18. This characteristic makes it possible to drive the gate 17 despite the presence of elements of small dimensions being on its trajectory.
• the support fixing 200 has a pair of power contactors 19 disposed on the outer surface of the wing of the fixing support 200 located on the side corresponding to the direction F of closing the gate. These contactors 19 are connected to the connector 10 of the electronic control card 6 of the motor 4. This pair of contactors 19 is positioned opposite a second pair of contactors 20 fixed on one of the columns 21, so that the two pairs of contactors 19 and 20 come into contact with one another when the gate 17 is in the closed position.
• the contactors 20 fixed on the column 21 are connected to an electrical power source.
• the electronic control card 6 comprises means for detecting the passage of the charging current from the battery 5 (by example in the form of a resistance associated with a threshold detector) which allow it to detect the end of travel of the gate when it is closed F.
• An infrared emitter 22 is fixed to the column 21 and connected to the aforementioned power source. This transmitter 22 is positioned opposite the detection cell 16 secured to the fixing support 200.
• the detection cell 16 is connected to the electronic control card 6.
• the electronic card 6 controls the stopping of the motor 4 and, if necessary, its rotation in the opposite direction.
• the electronic card 6 commands the stop and then, if necessary, the reopening O of the gate 17.
• the electronic card 6 commands the stop of the portal 17.
• the motorized unit 100 advantageously constitutes an autonomous assembly which does not require constraining wiring with an external power supply.
• a solar panel can be fixed on the gate and the emitter and the photosensitive cell can both be fixed on the fixing support 200 opposite a mirror or reflector installed on one of the columns.
• the motorized unit no longer requires any energy input via the contactors placed on one of the columns.
• the device opening and closing thus implemented is even faster to install since it does not require any installation of contactors or external energy sources.
• the invention also relates to electric locks for sliding gates.
• Manually operated sliding gates are generally provided with a lock comprising a hook-shaped bolt which can engage in a slot forming a keeper situated on the column on which the portal abuts.
• a lock comprising a hook-shaped bolt which can engage in a slot forming a keeper situated on the column on which the portal abuts.
• This device is particularly ill-suited to motorized sliding gates operated from a distance. Indeed, it requires that the user manually unlocks the lock each time he wants to control the opening of the gate.
• C. describes an automated hook lock that can be actuated either electrically or with a key.
• the device described comprises a mechanism that can be controlled electrically.
• This device comprises coils, a magnetic plate, levers and spring means making it possible to maintain a hook-shaped bolt in a lowered position.
• the magnetic field created causes the magnetic plate to move, which then releases a lever.
• the released lever disengages from the spring means which made it possible to maintain the hook-shaped bolt in the low position.
• the bolt is then driven by a succession of levers in the raised position. In this position, it can be disengaged from the keeper.
• the device also includes a barrel enabling the lock to be actuated using a key. When the user turns the key in the barrel, the barrel panet pushes the magnetic plate and in the same way as before, by a lever system, the hook-shaped bolt is moved to the raised position.
• This type of lock can therefore be controlled electrically by the automatic gate opening device. In the event of a power cut or the automatic opening and closing device not working, the lock can be released manually.
• the disadvantage of this device is that it includes many mechanical parts. It is therefore relatively expensive to manufacture and unreliable in the long term.
• the object of the present invention is to provide an electric lock for a sliding gate that is simple, robust, inexpensive and can be controlled by an automatic opening and closing device.
• the invention provides a locking device for a sliding gate, characterized in that it comprises an actuator, a lever element, one of the ends of which has a general hook shape, said end being able to be engaged in a keeper, and elastic means to keep the end of the element engaged in the keeper, the actuator being able to exert a force directly on the lever element to disengage the end of the hook-shaped element waste.
• This locking device can be installed on a motorized gate or not. If the gate is motorized, this locking device can be used with any type of motorized gate drive assembly.
• the proposed locking device comprises a simple mechanism, presenting a minimum of parts. This characteristic gives it several advantages.
• this device because it comprises few mechanical parts, this device has an advantageous cost and great ease of assembly. In addition, it can be made using mechanical elements with simple geometric shapes, therefore easy to machine and robust. This gives the locking device great reliability.
• the actuator is a linear output stroke motor capable of being controlled in two extreme positions.
• the actuator is able to be controlled by an automated gate opening and closing device
• the locking device comprises a manual lock capable of exerting a force on the lever-forming element to disengage the end of the hook-shaped element from the keeper,
• the manual lock is a cylinder lock having a swivel pin capable of exerting a force on a double lever system to disengage the hook from the strike,
• the locking device comprises a guide finger capable of being engaged in an orifice when the gate is in the closed position
• the end of the bolt forming a hook has an inclined outer surface capable of coming into contact with a rim of the keeper and of causing the element to engage in the keeper,
• the locking device comprises a cover to prevent access to the element when the gate is in the closed position

• the contact means comprise contactors capable of coming into contact with supply studs when the gate is in the closed position, the studs being movable in translation and comprising elastic means for keeping them in contact with the contactors as long as the hook element is not completely extracted from the keeper, -
• the external supply means are able to be controlled by an automated device for opening and closing the gate.
• the locking device 300 comprises an actuator 1 (of the car electric lock motor type) fixed to the bottom of the housing 82 and whose output axis 30 can translate between two extreme positions corresponding to a minimum extension and maximum extension along the axis X.
• the device 300 further comprises a bolt 50 in the general shape of a hook mounted pivoting about an axis 70 and having an extension 50 forming a lever.
• the hook portion 40 of the bolt 50 extends outside the housing, the hook 40 being oriented downwards.
• a torsion spring 60 keeps the part of the bolt 50 forming a lever resting on the end of the axis 30 of the engine.
• the translation of the axis 30 of the motor along the X axis causes the bolt 40 to rotate about the axis 70.
• the hook end 40 of the bolt is in the raised position.
• the spring 60 exerts a restoring force on the part of the bolt 50 forming a lever and brings the hook end 40 back to the low position.
• the device 300 is fixed to a sliding gate 17 by means of screws 80.
• a column 21 constitutes a stop when the gate 17 is in the closed position.
• the hook portion of the bolt 40 is located opposite a slot 90 formed in the column 21 constituting the keeper in which it can come to engage.
• a horizontal guide finger 83 is fixed to the housing 82. This finger
• the 83 is for example constituted by a rod whose end has a chamfer.
• This finger 83 is capable of coming to engage in an orifice 110 formed in the column 21 when the gate 17 is in the closed position.
• the gate 17 is closed, it is moved in the direction F.
• the hook 40 is in the low position.
• the finger 83 enters the orifice 110, guiding the portal 17.
• the end of the hook bolt 40 comprises an inclined outer surface 120 coming into contact with the lower edge 13 of the keeper 90 and constituting a guide allowing the rotation of the bolt 40 about its axis 70 in the opposite direction to the needles of a watch. This rotation generates the lifting of the hook end 40.
• This lifting allows the progressive engagement of the hook 40 in the keeper 90.
• the return spring 60 causes the rotation of the bolt 40 in the direction clockwise and engagement of the hook 40 in the keeper 90.
• a cover 140 secured to the housing 82 prevents access to the bolt 50 when the gate is in the closed position.
• This cover 140 consists of a U-shaped piece which envelops the horizontal part of the hook 40 of the bolt 50. In this configuration, it advantageously makes it possible to prevent a person from being able to lift the bolt 50 by sliding an element between portal 17 and column 21.
• the opening of the gate 17 is controlled.
• the motorized opening and closing device connected to the motor by the connections 150 controls the supply of the motor 81 for a predetermined period.
• the axis 30 of the motor 81 moves to the position of maximum extension, causing the bolt 50 to rotate about the axis 70 in an anticlockwise direction. This rotation generates the lifting of the hook 40 and its disengagement of the keeper 90.
• the gate 17 can then move in the opening direction O.
• the power supply to the motor 81 is cut, the axis 30 returns to the minimum extension position and the hook 40 returns to the low position.
• the gate 17 is opened manually.
• a cylinder lock 160 is actuated using a key.
• the bit 170 of the barrel 160 pivots and comes to bear on a lever 180 which can pivot around an axis 190 and comes to bear on the part of the bolt 50 forming a lever.
• This double lever system advantageously allows to multiply the torque exerted by the user on the key.
• the rotation of the key in the barrel 160 causes the rotation of the bolt 50 anticlockwise. The same way as in FIG. 3, this rotation generates the lifting of the hook 40 and its disengagement of the keeper 90.
• the gate 17 can then be moved manually in the direction O.
• FIG. 11 shows an example of means for supplying the device for locking the gate 17.
• These supply means comprise two fixed contactors 29 positioned on the lateral face of the housing 82 coming into contact with the column 21. These two contactors 29 are connected by two conductive wires 32 to the connections 150 for supplying the motor 81.
• the means of 'supply also include two movable pads 31 positioned on the column 21, facing the contactors 29. The pads 31 are connected to a source of electrical power. These studs 31 come into contact with the fixed contactors 29 when the gate 17 is in the closed position.
• the supply pads 31 are movable in translation in the opening direction of the gate 17. Elastic means (not shown) keep the movable pads 31 in a position of maximum extension in the direction of the gate 17.
• the motorized opening and closing device controls the supply of the motor 81 for a predetermined period. A voltage is then applied between the supply studs 31. The motor 81 actuates the bolt 50 and causes it to disengage from the keeper 90. Simultaneously, the gate 17 moves in the opening direction O.
• the pads 31 are kept in contact with the contactors 29 by the elastic means. These studs 31 have a sufficient length to ensure this contact during the start of the opening of the gate 17. The hook 40 is thus held in the high position as long as the studs 31 are in contact with the contactors 29. This contact is not broken and the supply to the motor 81 is only cut off when the hook 40 is completely extracted from the keeper 90.
• these comprise a solar panel and a battery integrated in the housing 82.
• the battery makes it possible to supply the voltage necessary to control the motor 81.
