Definitions

  • ABSTRACT A sliding door is operated automatically by means of a nut and threaded rod which are driven by a reversible motor and constitute a reversible-action motion converter.
  • the motor supply circuit comprises a switchable speed-reduction resistor, a protective resistor in series with the motor and a switchable voltage-1imiter which can be connected in shunt across the motor terminals at the end of travel of the door-leaf.
  • doors of the type comprising a leaf which operates only in sliding motion or in other words remains substantially in the same plane during the entire operation of the door. It should be understood, however, that the invention also applies to doors in which a sliding movement is combined with various other movements. For example, the invention also applies to doors having multiple leaves articulated in a bellows arrangement or to doors of the type which may or may not comprise a single leaf and operate in a movement of translation and disengagement.
  • doors of the sliding motion type There are various known types of doors of the sliding motion type and various systems for controlling these doors.
  • the invention applies to doors in which the movement is controlled in rotation by a motor and in particular to doors of the type having at least one leaf, the sliding motion of said leaf controlled by a nut associated with a threaded operating rod driven in rotation by a motor which is capable of operating in both directions. Doors of this type are employed especially in public transport vehicles and in public buildings. These doors are often required to operate automatically at a very high rate with the minimum of incidents and maintenance contingencies while satisfying strict conditions of safety.
  • the aim of the invention is to overcome these disadvantages by making it possible to provide for a door of the sliding-motion type a control system which offers complete safety and is both economical and rugged as well as being easy to mount and to maintain.
  • the invention is directed to an automatic control system for a sliding-motion door having at least one leaf rigidly fixed to a nut associated with a threaded operating rod driven in rotation by a reversible motor associated with an elastic coupling system which is deformable in rotation; the supply circuit of the motor comprises a speed-reduction resistor which can be changed-over by means of a switch controlled by the displacement of the door-leaf.
  • the system aforesaid is characterized by the combination of the following particular features:
  • the supply circuit of the motor comprises a protective resistor permanently mounted in series with the motor, and a voltage limiter which can be changed-over by means of a second switch controlled by the displacement of the door-leaf so as to connect the voltage limiter in shunt across the motor terminals at the end of the travel of the door-leaf, the nut and the threaded operating rod being such as to constitute a reversible-action motion converter.
  • the longitudinal force applied to the door-leaf can thus be also limited by making a consequent selection of values of the elements of the electric supply circuit. This makes it possible to prevent any bodily injury during closure since the driving torque on the operating rod has then decreased to a considerable extent. If the motor has been stopped prior to the normal end of travel of the door-leaf, said leaf can then continue its automatic closing movement if so required, this being achieved by virtue of the elastic coupling system and the permanent motor torque.
  • FIG. 1 is a general diagram of a door equipped with an automatic control system in accordance with the invention
  • FIG. 2 is a detailed illustration of the deformable elastic coupling system and the supply circuit of the motor shown in FIG. 1.
  • the door which is equipped with the automatic control system comprises a sliding leaf 1 rigidly fixed to a nut 2 which is associated with a threaded operating rod 3. Said rod can be driven in rotation by a reversible electric motor 4 associated with an elastic coupling system 5 which is deformable in rotation.
  • the motor 4 comprises a supply circuit 6 connected to the terminals 6a of a supply line by a change-over switch 6b.
  • a speed-reduction resistor 7 can be changed-over by means of a switch 8 controlled by contactors 8a, 8b which are actuated as a result of the displacement of the door-leaf 1. This device makes it possible to moderate the speed of the door-leaf at preselected points of its opening and closing travel.
  • the device aforesaid is characterized by the combination of the subsequently described features of the supply circuit 6 of the motor 4 and of the motion converter constituted by the nut 2 and the threaded operating rod 3.
  • the supply circuit 6 of the motor 4 comprises a protective resistor 11 permanently connected in series with the motor 4 and a voltage limiter 12 which can be changed-over by means of a second switch 13 associated with the switch 8 and controlled in the same manner as this latter by the displacement of the door-leaf 1 so as to connect the voltage limiter 12 in shunt across the terminals of the motor 4 at the end of travel of the door-leaf l.
  • the nut 2 and the operating rod 3 constitute a reversible-action motion converter for actuating the doorleaf 1 in translational motion under the action of rotational motion of the rod 3 or conversely to drive the rod 3 in rotational motion when action is produced on the door-leaf 1 so as to displace this latter in translational motion. especially under conditions of emergency hand operation by means ofa handle 14 as is explained hereinafter.
  • the operating rod 3 of ground steel for example. has a hollow screw-thread of trapezoid profile.
  • a thread pitch of 60 to 120 mm which permits both rapid operation by the motor and easy emergency operation by hand when making use of the handle 14.
  • the nut 2 is a ball circuit nut and has bearings so adjusted as to slide with the minimum friction over the cylindrical surface of the threaded rod 3.
  • a separate control device 15 placed within the reach of users serves to cut-off the current supply to the motor 4 by means of an emergency switch 16 (as shown in FIG. 2).
  • the elastic coupling system 5 comprises a cage 21 substantially of revolution and keyed along its axis on one end of the shaft of the motor 4.
  • An axial rod 22 mounted on two bearings contained within the cage 2] is capable of rotating with respect to said cage and is coupled to the threaded rod 3 which serves to operate the door-leaf l.
  • the axial rod 22 which is similar to the threaded rod 3 is provided in the same manner as this latter with a hollow screwthread having a trapezoidal profile and associated with a nut 23 which is similar to the nut 2 and capable of sliding within the cage 21 without rotating.
  • Oppositely-acting helical springs 24a, 2417 which are mounted around the axial rod 22 between each end of the cage 21 and the nut 24 serve to maintain this latter substantially at the mid-length of the cage when the system is at rest and when the torque exerted between the motor 4 and the threaded rod 3 is Zero.
  • the motion converter constituted by the axial rod 22 and the nut 23 is a reversible-action converter of the same type as the unit constituted by the threaded operating rod 3 and the nut 2.
  • the strength of the springs 24a, 24b which determines the elasticity of the elastic coupling system 5 is chosen so as to take various operating conditions into account as explained hereinafter.
  • the values of the two resistors 7, 11 as well as the value of the voltage defined by the voltage limiter 12 are preferably chosen so as to ensure complete slowing-down and stopping of the motor 4 without any danger, this being achieved under the action of the resisting torque exerted on the operating rod 3 by the nut 2 when said torque attains a value corresponding to a predetermined longitudinal effort on the door-leaf 1.
  • the values and characteristics mentioned in the foregoing are advantageously selected so as to limit the current intensity within the stationary motor 4 to a value which is sufficiently low to allow the normal operating voltage at the terminals of the motor supply circuit to be maintained without any difficulty.
  • the motor 4 tends to drive the elastic coupling system 5 and the rod 3 so as to displace the nut 2 and the door-leaf l in the direction of opening or closing of this latter.
  • one of the contactors 8a, 8b is accordingly actuated by the door-leaf and initiates the remote operation of the switch 8 (as shown in FIG. 2) of the supply circuit 6 of the motor 4.
  • the switch 8 thus connects the motor 4 in series with the speed-reduction resistor 7.
  • the second switch 13 associated with the switch 8 connects the voltage-limiter 12 in shunt across the terminals of the motor 4.
  • the device is arranged by means of a follow-up control relay (not shown) so that the above-mentioned action of the switches 8, l3 continues as long as the control changeover switch 6b is maintained in the same position.
  • the torque of the motor 4 is accordingly limited so as to permit complete slowing-down and stopping of the motor and of the threaded rod 3 without excessive shock under the action of the resisting torque exerted on the rod 3 by the nut 2 (shown in FIG. 1) when said resisting torque attains a predetermined value corresponding to a predetermined longitudinal force applied to the door-leaf 1.
  • the elasticity of the coupling system 5 ensures damping of the rotational motion of the motor 4 and of the rod 3 at the end of travel of the door-leaf l.
  • the resultant deformation of the springs 24a, 24b provides favorable conditions for starting of the system in the reverse direction by virtue of the storage of energy which is thus acheived.
  • a motor 4 of commercial type which is designed to operate normally at a direct-current voltage of 220 volts, and a running speed of 1000 revolutions per minute on low load corresponding to a power level of the order of 250 watts.
  • the supply voltage at the terminals 6a is only 90 volts.
  • the ohmic resistance of the motor 4 is 13 ohms.
  • the resistors 11 and 7 have values of 15 and 62 ohms respectively.
  • the voltage-limiter 12 which is constituted by a Zener diode limits the voltage developed across the terminals of the motor 4 to 24 volts. This value is substantially eight times lower than the rated operating voltage.
  • the motor 4 operates at an effective voltage of the order of volts, at an intensity of approximately 0.7 amp, and at a running speed in the vicinity of 400 revolutions per minute.
  • said running speed corresponds to a linear velocity of the order of 0.5 in per second in the case of the door-leaf 1.
  • the running speed of the motor 4 is only revolutions per minute corresponding to a velocity of l 1 cm per second in the case of the door-leaf l.
  • the current intensity is then 0.7 amp in the motor 4 and 0. l6 amp in the voltage-limiter l2.
  • the longitudinal force applied to the door-leaf 1 is accordingly of the order of Kg, for example.
  • the deformation of the springs 24a, 24b then corresponds substantially to one-quarter of a revolution of the axial rod 22, namely mm of deflection for a screw-thread having a pitch of 80 mm per revolution.
  • the longitudinal force applied to the door-leaf l by the motor 4 in the stationary position can be adjusted to a predetermined value by selecting in consequence the torque of the motor 4 and the thread pitch of the operating rod 3.
  • the mechanisms and the circuit 6 of the motor 4 are particularly simple, rugged and economical.
  • the elasticity of the elastic coupling system 5 facilitates start-up of the system in each direction and makes it possible to employ a motor 4 of relatively limited power which is less cumbersome and easier to maintain at a suitable temperature.
  • all the elements of the circuit 6 can take up relatively little space, taking into account the low power of the motor 4.
  • the elastic coupling system may be designed in a number of different alternative forms such as in particular a spring which works in torsion.
  • the voltage-limiter 12 need not be a Zener diode but can comprise a number of dif- 6 ferent equivalent complementary resistors connected in series with the motor 4.
  • the operation of the switch 13 of the voltage-limiter 12 can be retarded or advanced with respect to the operation of the switch 8 of the speed-reduction resistor. This makes it possible to obtain a more progressive variation of the speed of the door-leaf 1, especially if this latter has high inertia.
  • An automatic control system for a sliding-motion door having at least one leaf rigidly fixed to a nut associated with a threaded operating rod driven in rotation by a reversible electric motor associated with an elastic coupling system which is deformable in rotation, the supply circuit of the motor being provided with a first switch and a second switch, a speed-reduction resistor which can be changed-over by means of the first switch controlled by the displacement of the door leaf.
  • the supply circuit of the motor includes a protective resistor permanently mounted in series with the motor, and a voltage limiter which can be changedover by means of the second switch controlled by the displacement of the door leaf so as to connect the voltage limiter in shunt across the motor terminals at the end of travel of said door leaf, the values of the two resistors and the threshold values of the voltage limiter as well as the characteristics of the motor being so selected as to limit the current intensity in the motor, when said motor is at a standstill, at a sufficiently low value to maintain the normal operating voltage at the terminals of the motor supply circuit, said nut and said threaded operating rod moreover constituting a reversible-action motion converter.
  • said elastic coupling system comprises a cage containing a nut capable of sliding within the cage without rotating and an axial rod similar to said operating rod of the door, oppositely acting springs mounted between said cage and said sliding nut, said cage and said axial rod being respectively coupled to the shaft of said motor and to the
