Definitions

  • the subject of the invention is a device for stopping a mechanism driving a member such as a door leaf, window or sliding roof and in particular a device intended to make it possible to shut down the motors which drive the windows of a motor vehicle.
  • patent publication DE AS 12 10690 describes a device for shutting off the drive motor of a window sash: in the event of an overload, a safety relay establishes a connection between the power supplies of the power relays controlling one and the other of the directions of rotation of the motor, so as to excite the two relays to stop this motor independently of the position of the contacts of its manual control.
  • This device eliminates the need for limit switches; on the other hand, it must also stop the engine when the user, by carelessness, leaves his hand on the edge of the glazing.
  • the criterion used to stop the motor is the increase in torque which occurs in the event of an overload and leads to an increase in the current draw of the motor. It therefore stops only when it supports excessive effort, which creates a significant risk of injury to the part of the body that is caught.
  • Patent publication DE AS 15 30992 describes an electrical solution: in this case, a third brush lowers the torque characteristic of the mo speed as a function of the movement in the closing direction of the leaf.
  • the friction clutch can be locked by a dog clutch engaged by means of an additional hand switch.
  • the dog clutch takes place automatically when operating in the direction of opening the window.
  • Patent publication DE OS 15 80284 also envisages fitting light barriers to the doors of vehicles with automatic closing, but it should be noted that the operating requirements of such doors differ significantly from those of the sliding windows of vehicles.
  • the edge of the leaf at least on the part which, in the open position appears bare inside the frame, is provided with a detector formed of an electrical conductor wire connected to a circuit electronic servo placed downstream of a manual control reversing contactor and which, when closing, reverses in turn supplying the motor as soon as a foreign conductive body comes into contact with it or approaches it sufficiently to modify its capacity.
  • the detector is inserted at the output of an oscillator stage preceding a detection stage and an all or nothing control stage.
  • the detector dampens the oscillations of the oscillator.
  • the detection stage detects the attenuation of the signal and reverses a contact via the all or nothing control stage.
  • this solution has a serious defect if the sensitivity of the device is sufficient to cause the operation not only when the body comes into direct contact with the contactor but also, for example, when a piece of clothing is interposed so that the triggering of the safety is due only to the capacitive action. Indeed, at the moment when the edge of the glazing approaches the closing zone, the presence of the metal frame of the bodywork or of the window frame is detected a little before the complete closing has cut the power supply to the motor. and it triggers the reopening. As a result, if the sensitivity is high, the circuit does not allow the window to be closed.
  • the main object of the invention is to avoid this drawback. To this end, it uses a similar circuit but where the oscillating stage is a stage of high sensitivity of which at least during the closing, the damping causes the opening of a contact which cuts the control of the motor, and where a auxiliary circuit temporarily deactivates the detector when it is energized. Thanks to the circuit according to the invention, it becomes possible, by a new closing order using the contactor, to complete the closing of the window if the detector placed on the edge of the window prematurely cut the power supply to the motor. when this edge approached the metal frame, or even, thanks to an approach signal, to cause the automatic crossing of the incomplete closed position in question. The opening of the window is made possible by the fact that the detection is neutralized at least at the start of the race, when the position of the manual control switch is reversed.
  • the auxiliary circuit according to the invention is a tilting circuit which passes from its first state to the second for a short time when its input is energized, then neutralizing the detection stage of the main circuit; this short duration may be, for example, of the order of 0.5 seconds.
  • this tilting circuit will be subordinated to an approach contact which will put it out of service in the intermediate positions of the leaf, thus restoring the immediate functioning of the safety.
  • the servo circuit can be supplied symmetrically, thus operating on opening and closing subject to its neutralization in the extreme zones.
  • the invention which is of particular interest when leaves are used without framing and in particular on light windows such as windows of motor vehicles, can however be applied to the fencing of bays such as French windows or one or more sliding leaves and ensures, under the same conditions, the safety of manually operated or automatically closing devices such as elevator doors.
  • a motor vehicle door 1 comprises a window frame 2 mounted on a box 3, inside of which there are slides, not shown, which carry the window 4.
  • the box 3 contains a motor 5 connected to the lower edge of the latter by means of a connecting rod not shown.
  • the edge 6 capable of coming to the inside of the frame in some position of the glass is coated with a detector 7 formed of a conduc- : electric eur.
  • this detector extends from location 8 to location 9; in fact, here, it covers the edge of the glass over the entire distance between location 8 and location 10.
  • Location 8 is external to the guide post so that there is no contact between it and the detector 7. If the latter extends to the location of one of the slides supporting the glass 4, it is necessary to isolate this slide. Finally, where the window 4 enters the box 3 there are rubber sealing profiles; these are not in contact with the detector 7 which is only deposited on the edge of the glass.
  • the detector 7 On the lower edge 11 of the window 4 the detector 7 is connected to the central conductor, or core 12, of a coaxial cable 13 whose sheath 14 is not connected at this location.
  • the coaxial cable 13. is connected to a servo circuit 15 inserted in the motor supply circuit 5.
  • the circuit 15 is represented by blocks in FIG. 2. It has an oscillator stage 16 to which the outputs of the detector 7 or, if preferred, coaxial cable 13, are connected, and a detection stage 17.
  • the oscillator 16 supplies the detector 7 with a frequency of the order of MHz, for example with 200 kHz.
  • the detector 7 thus works as an antenna and the oscillator 16 is mounted in such a way that when a foreign body comes into contact with it, the amplitude of the transmitted signal is attenuated.
  • the attenuation occurs not only when the body in question is truly conductive but also when its conductivity, quite reduced in itself, however constitutes a mass of sufficient capacity to dampen the oscillations of the circuit.
  • the attenuation of the signal from the oscillator is perceived by the detection stage 17 which then supplies an all or nothing signal to a control stage 18, which in this case cuts the power supply to the motor 5.
  • the oscillator 16 consists of two inverters JI, J2 connected in series, the output of the inverter J2 being looped over the input of the inverter J1 via a capacitor CI.
  • a resistor R1 is inserted between the input of the inverter J2, that is to say the output of the inverter J1 and the capacitor C1.
  • the resistor RI and the capacitor C1 determine the oscillation frequency.
  • the output of the oscillator 16 is connected on the one hand to the core 12 of the coaxial cable, therefore to the detector 7 by the coupling capacitor C2, on the other hand to an impedance adapter OP by the coupling capacitor C3.
  • a voltage divider made up of resistors R2 and R3 determines the working point of the amplifier OP; the latter is coupled to a frequency compensator circuit which includes in series the resistor R4 and the capacitor C4.
  • the output of the amplifier OP is connected via a coupling capacitor C5 to the sheath 14 of the coaxial cable 13 so that the two con - ducers 12 and 14 are driven in phase by two signals of the same frequency.
  • the capacity of the coaxial cable 13 is thus compensated because there is never at any point of the latter a potential difference between its core 12 and its sheath 14, which allows the cable length to be adapted without other precautions from door 1.
  • connection cable moves in the box 3, which would have a very difficult influence on signal damping if it were not for not a coaxial cable.
  • the output of the oscillator connected to the core 12 therefore to the detector 7 is of high impedance; towards the sheath 14 due to the presence of the amplifier OP, it is on the contrary of low impedance. As a result, the detector 7 is sensitive to damping.
  • the core 12 and with it the output of the oscillator 16 are connected by a coupling capacitor C6 to the detection stage 17, formed of two inverters J3 and J4, of which a resistor R5 fixes the working point. Between the two inverters J3 and J4 is a rectifier diode D1. In addition, the input of the inverter J4 has a resistor R6 and a capacitor C7 in bypass.
  • the inverter stages J1 to J4 can belong to a single integrated circuit such as the IC HCF 4069 circuit from SIGNETICS.
  • CMOS complementary metal-oxide-semiconductor
  • a charge adapter stage 19 is provided, consisting for example of an integrated circuit in TTL technique. It includes two inverters J5 and J6 which may belong to a commercial integrated circuit of the SN 75 491 type.
  • Resistors R7 and R8 regulate the working points of the reversers J5 and J6.
  • the output of the inverter J6 is connected by a resistor R9 to the base of a DARLINGTON amplifier formed by two transistors T1 and T2.
  • the damping circuit described is connected by a blocking diode D3 to the pole 20 of the vehicle supply network and by a diode D4 to the pole 21 of this network.
  • the relay contact K connects the pole 20 to the terminal 22 of the motor 5.
  • the transistors T1 and T2 are made conductive by the logic signal 1 which comes out of the power amplifier 19 so that the relay contact K, open by winding W, cut the motor 5.
  • a filter capacitor C8 is placed between the diodes D3 and D4 to eliminate the parasitic voltages.
  • the servo circuit cannot itself generate parasites around the detector 7 because the emission voltage of the antenna formed by the latter is much lower than the disturbing voltages generated by the engine of the vehicle in which the device is incorporated and the latter is only in service when the con engine ignition tact is on.
  • FIG. 4 represents the electrical connection of the motor 5 via the servo circuit 15 and of a window control switch 23 of the current type equipped with a control button 24 connected to the positive pole 25 and to the negative pole 26 of the on-board network.
  • the contactor 23 has two change-over contacts 23 'and 23 ". In the position shown in FIG. 4, these two contacts are placed so that the motor 5 raises the window 4.
  • the contact K opens so that the motor 5 stops and the closing of the window is interrupted as a last limit, the contact K opens when the window 4 arriving in the closed position, the detector is influenced by the frame 2.
  • the contactor button 24 is pressed so as to reverse the two contacts 23 'and 23 ", connecting the first to the negative pole 26 and the second to the positive pole 25.
  • a negative potential then appears on pole 20 of the circuit 15 which blocks the diode D3 Likewise the positive potential appeared on the pole 21 blocks the diode D4
  • the control circuit 15 is therefore no longer supplied so that the oscillator 16 ceases to operate and the detector 7 is neutralized.
  • the relay contact K therefore closes, and the motor 5, the supply of which, between the contacts 23 'and 23 ", is reversed, causes the window 4 to descend.
  • FIG. 3 finally shows the auxiliary circuit A according to the invention and which makes it possible to avoid this drawback.
  • the auxiliary circuit which is practically in parallel with the filtering capacitor C8, is shown in FIG. 5. It is a tilting circuit controlled by a monostable rocker KS, for example in the form of an integrated circuit NE555, sold as the integrated circuit SN 75 491 by the firm TEXAS INSTRUMENTS.
  • KS monostable rocker
  • the control input of the flip-flop KS is mounted in bypass on a resistor R10 and a capacitor C9 connected to the input terminal 27. As soon as the voltage appears on the auxiliary circuit A, a voltage is established in the branch C9 -R10. A start pulse is thus transmitted to the KS flip-flop when the control switch 23 closes.
  • This starting pulse switches the output of the flip-flop KS, to which is connected, by means of a resistor R15, the base of a transistor T3 which is thus made conductive.
  • the transistor T3 is connected via a resistor R16 to the input resistor 9 of the base of the transistor T1.
  • the DARLINGTON amplifier consisting of the transistors T1 and T2 is therefore blocked independently of whether the detector 7 dampens the oscillations of the oscillator 16 or not, so that the winding W cannot open the contact K.
  • the duration during which the flip-flop KS makes the transistor T3 conductive and therefore neutralizes the detector 7 is fixed by the connection of this flip-flop to the circuit consisting of the capacitor C10 and the resistor R13. These last two members are dimensioned so that the blocking time is of the order of 0.5 s for example. Resistors R12 and R14 provide the necessary initial supply voltage.
  • the time during which the KS rocker keeps the DARLINGTON amplifier blocked is fixed in such a way as to allow the window 4 to reach without any doubt until its closed position.
  • the diodes D5 and D6 are blocked and the operation of the circuit is identical to that which has been described above.
  • the diodes D3 and D4 are blocked as before but the diodes D5 and D6 are made conductive and supply power normally the circuit, as a result of which the contact of the detector with a foreign body interrupts the movement of the window both during opening and closing.
  • the presence of the lever does not only allow the window to be brought into the fully closed position either by manual action in the closing direction on the control button 24, or automatically as described above. It ensures in both directions, both during opening and closing, the crossing of the imperfect closing zone and, if desired, plays a similar role at the end of opening thanks to a symmetrical action on the contact 29.
