Definitions

  • the present invention relates to a motorized control device for opening and closing a gate. It is more particularly, although not exclusively, a device intended for an external gate with two pivoting leaves and comprising, for actuating each leaf, an "tubular" electric motor mounted along the vertical pivot axis of the leaf and housed in the upper part of a hollow vertical lateral element of the leaf, the motor stator being integral with the upper pivot of the leaf while its rotor is linked in rotation with an element of the leaf, by means of a speed reducer.
  • a motorization device of this kind for a portal with two leaves, is already described in French patent 2,450,334.
  • the main advantage of such a motorization device is that it is entirely housed inside the elements of the portal. that it must operate, in particular being integrated inside the lateral uprights of the two leaves, these uprights having a tubular structure.
  • the present invention aims to eliminate these drawbacks by providing an improved motorized control device in which the same mechanism provides for each leaf the functions of pivoting in both directions, of stopping at the end of the opening stroke or of closing, and locking in extreme positions, with the aim of constructive simplification, greater reliability, security, economy and rapid adaptation in the event of conversion of a manual gate.
  • the invention essentially relates to a motorized control device for the opening and closing of a gate, of the type specified above, in which the drive shaft of the or each leaf, shaft of which the axis coincides with the vertical pivot axis of the leaf, is coupled to an element of the leaf by means of the "cam" type, which on the one hand ensure a rotational connection between the drive shaft and the leaf when the latter is free to pivot around the aforementioned axis, and which on the other hand are capable of causing a limited vertical movement of the leaf, by transforming the rotational movement of the drive shaft into a movement of translation of the element considered of the leaf along the aforementioned axis, when this element is prevented from pivoting.
  • the “cam” type connection means, between the drive shaft and an element of the leaf are constituted, in a first embodiment of the invention, on the one hand, by at least one roller mounted rotating on a horizontal axis carried by the drive shaft, and on the other hand, by at least one inclined double ramp forming an inverted "V" and integral with the aforementioned element of the leaf, the or each roller cooperating with the double ramp corresponding inclination so as to cause a limited lifting of the leaf, when the latter is prevented from pivoting.
  • the rollers remain at the upper point of the inverted "V” formed by the double ramps, and any rotation of the drive shaft is accompanied by a rotation of the same value of the ramps , so the leaf.
  • the device also advantageously comprises an electrical end-of-travel contact, causing the motor to stop, which is arranged so as to be actuated by an element of the leaf after the latter has been raised to a predetermined height. Stopping the motor when the leaf reaches an extreme position can thus be automatically controlled, simply by placing a stopper on the path of the leaf whose height is greater than the predetermined height mentioned above. This stopper constitutes for the leaf an obstacle which, when encountered, causes the leaf to be raised to the height for which the limit switch is actuated. After cutting off the power supply to the motor, the leaf can return by itself to the low position, if a "reversible" motor-reduction unit is provided.
  • spring means which create an additional force for applying double ramps inclined on the rollers.
  • It may be a mechanical spring, in particular of the helical type and coaxial with the drive shaft, or a gas spring, also forming a damper.
  • the gas spring coaxial with the drive shaft, has its upper end connected to said shaft, and its lower end linked to a tube with a vertical axis, integral with the part comprising the double inclined ramps.
  • the leaf is rotated in the "low” position
  • the “cam” type connecting means between the drive shaft and an element of the leaf, consist, on the one hand, of at least one roller mounted rotating on a horizontal axis carried by the drive shaft and, on the other hand, by at least one double ramp inclined in the general shape of "V" and integral with the aforementioned element of the leaf, the or each double ramp inclined being applied under the roller or one of the rollers by spring means exerting on the aforementioned element of the leaf a vertical force oriented from bottom to top and of value greater than the weight of the leaf.
  • the connecting means of the "cam” type still advantageously comprise, on either side of the or each double inclined ramp forming a "V", two secondary parts with concavity facing towards the top, less deep than the main "V” part and separated from the latter by beaks. Thanks to this particular cam profile, when the roller “rises” along one of the ramps, it finally crosses the spout located at the top of the ramp to “fall” in one of the concave abutments.
  • roller and the cam profile are thus immobilized relative to each other in a relative position for which the leaf is held in the "low” position, which ensures the stopping and the locking (in cooperation with the stop ), in the closed and open positions, the leaf is immobilized in the locking stop safely, even in the wind.
  • the inclined double ramp or ramps can be formed on a part which has a central passage through which the drive shaft passes, and which is connected axially and in rotation with the aforementioned element of the leaf.
  • the part provided with inclined ramps can be directly secured to the leaf element, such as an upright, or be linked in rotation to this element by means of a torque limiter.
  • all the components of the device are housed inside the leaf, more particularly by being grouped in the lateral upright situated on the side of the pivot axis, below the upper pivot.
  • the operating principle obviously requires that the mounting of the upper part of the leaf, as well as the lower pivot, allow a vertical translational movement, over a stroke of a few centimeters, to allow the leaf to be raised.
  • the motorized control device eliminates all the electromagnetic locking means placed at distance, or other independent locking devices, and consequently any passage of electric cables in the elements of the leaves.
  • the vertical movement of the leaf also makes it possible to solve the problems of blocking on the ground by the effect of frost in winter, or due to small obstacles present in the path of the leaf.
  • a gate with a motorized control device can be easily equipped, in particular with regard to the arrangement of the locking stops, so as to be maneuverable also manually, in particular in the event of power cut. power supply.
  • the portal shown in FIG. 1 comprises two leaves 1 and 2 which are pivotally mounted, around vertical axes, by means of upper lateral 3 and lower 4 pivots, anchored for example in masonry posts 5.
  • Each leaf 1 or 2 has a rectangular frame formed mainly by two tubular lateral uprights 6 and 7, connected together by at least one upper horizontal element 8 and at least one lower horizontal element 9.
  • the interior lining of the leaves 1 and 2 can be produced by a bar 10 and / or a filling 11, according to any known arrangement.
  • each leaf 1 or 2 describes a pivoting of approximately 90 °, between a first extreme position defined by a common central stop 12 is the closed position, and a second extreme position determined by a lateral stop respectively 13 , 14, which is the full opening position (indicated briefly by the dashed line), the stops 12, 13 and 14 being fixed to the ground.
  • the two leaves 1 and 2 being equipped with similar motorization devices, only the device associated with one of these leaves, such as the leaf l, will be described below. More particularly, a first embodiment will first be described, with reference to FIGS. 2 to 8.
  • the motorization of the opening and closing of the leaf 1 is ensured by an electric "tubular" geared motor 15, with two directions of rotation, arranged along the vertical pivot axis 1-6 of the leaf 1.
  • the motor- reduction gear 15 is housed in the upper part of the lateral upright 6 of the leaf, below the upper pivot 3, the stator of the motor being made integral with the upper pivot 3.
  • the lateral upright 6 of the leaf 1 is pivotally mounted around the vertical axis 16, and also sliding along this axis 16, by means of at least two guide rings 17 and 18 surrounding the stator of the geared motor 15 This mounting allows an additional movement of vertical translation of the entire leaf 1, the lower pivot 4 being produced so as to allow this translational movement.
  • the drive shaft 19 is crossed diametrically by a horizontal axis 20, on which are mounted rotating two opposite rollers 21 and 22, of frustoconical external shape.
  • the piece 23 has a central passage 24 crossed by the drive shaft 19 , and it mainly comprises two double inclined ramps 25 and 26, diametrically opposite.
  • Each double ramp 25 or 26 has a rising part and a falling part, which are connected at their upper part so as to form an inverted "V", the running surfaces of the ramps being turned downwards.
  • the two rollers 21 and 22 respectively cooperate with the two double ramps 25 and 26, each double ramp bearing on one of the rollers which can roll along this double ramp.
  • the drive shaft 19 forms, at its lower end, a yoke to which is linked, by means of a pin 27, the upper end of a gas spring 28 also arranged along the vertical axis 16, at the interior of the lateral upright 6.
  • the rod 29 of the gas spring 28 ends, at its lower end, by a nozzle 30 which is linked, by means of a small horizontal axis 31, to the lower end d 'a tube 32 of vertical axis, surrounding the gas spring 28.
  • the upper end of the tube 32 is made integral with the cam part 23, therefore of the upright 6.
  • the gas spring 28, acting from top to bottom on the part 23 via the tube 32, tends to apply the double inclined ramps 25 and 26 against the respective rollers 21 and 22, pulling the upright 6 downwards.
  • the own weight of the leaf 1 and the additional effort created by the gas spring 28 tend, normally, to maintain the two rollers 21 and 22 in the region of the tip of the " ⁇ " 'formed by the double ramps 25 and 26, as shown more particularly in FIG. 2.
  • the leaf 1 then occupies its normal low position, also indicated in FIG. 3.
  • the torque imparted by the gear motor 15 to the drive shaft 19 can be transmitted to the leaf 1 via the roller carrier axis 20. the rollers 21 and 22, and the cam-forming part 23, to pivot the leaf in the opening or closing direction around the axis 16.
  • the gear motor 15 has a built-in electrical limit switch 34, which is actuated by the upper guide ring 17 of the upright 6 if the leaf 1 has been raised from a predetermined height h, for example equal to 3 centimeters. At the moment when the ring 17 actuates this contact 34, the electrical supply to the geared motor 15 is immediately interrupted, so that the drive shaft 19 no longer communicates, by means of the door shaft. -galets 20, the torque converted into lifting force by the part 23.
  • the ring 17 does not actuate the electrical limit switch 34. This occurs in the case where the leaf 1 encounters in its path an obstacle of height less than the height h; in such a case, after lifting the leaf 1 over a height equal to that of the obstacle, the gear motor 15 continues to transmit a torque to the leaf 1 and the latter crosses the obstacle, after which it descends into position low and can still continue its pivoting movement.
  • the lower part of the leaf 1 comes first to abut against the external flank of the raised part 36.
  • the leaf 1 After having been thus lifted, the leaf 1 is again driven in rotation and it completely crosses the raised part 36, as shown in FIG. 6, then it "falls" on the hollow part 38, the width of which corresponds substantially to the leaf thickness I.
  • the raised parts 36 of the stops can be removable, to also allow the gate to operate in the event of a temporary cut in the electrical supply to the geared motors.
  • the gas spring 28 ensures the descent of the leaf 1 or 2 after each obstacle crossing, whether it is an obstacle placed voluntarily (stop) or involuntarily on the past of the leaf. This spring 28 also opposes the effect that the wind could have on the rotation of leaf 1 or 2, and it also opposes manual lifting of the leaf by a malicious person.
  • FIGS 9 to 16 relate to another embodiment; in these figures, the elements which correspond to those previously described are designated by the same references.
  • FIG. 9 again partially shows a leaf 1, comprising on the side of its articulation a tubular lateral upright 6, at the top of which a horizontal element 8 is connected.
  • the leaf 1 is pivotally mounted, around a vertical axis 16, by means of lateral pivots, FIG. 9 showing only the upper pivot 3 anchored in a masonry part 5, such as a post.
