Definitions

  • This invention relates to an automatic system for swinging doors, that is a device for automating the operations of opening and closing swinging doors.
  • command and control means combined with suitable sensors to open the door when a person is ready to pass through it and close it immediately afterwards.
  • swinging doors have a leaf weighing less than 150-180 kg and a width not exceeding 1200-1600 mm they can be defined as being "light". Such doors find particular application in entrances for pedestrians, for example for offices or shops.
  • the dimensions and weight of the door therefore determine the maximum torque which must be capable of being transmitted to the operating arm in order to move the door, and therefore the measuring of the entire automatic system.
  • Automatic systems for swinging doors essentially comprise a driving electric motor and a reduction unit connected thereto which transmits the rotation of the motor to an arm operating the door.
  • the motor is generally an electric motor with a rotation speed of the order of 1000-2000 r.p.m. and the reduction unit must therefore reduce this rotation speed to values capable of controlling the movement of the leaf, both when accelerating and when braking.
  • a worm-gearwheel coupling is not suitable for reversing the transmission of forces and therefore the application of an external force to the door opposite that exerted by the automatic system at that moment runs the risk of causing structural failure of one of the gears in the force transmission chain.
  • the object of this invention is to provide a device for swinging leaves provided with a reduction unit which can overcome at least some of the problems mentioned above, while at the same time maintaining the properties of high reliability and regular operation.
  • 1 indicates the device (an automatic system) for opening and closing swinging leaves as a whole.
  • Device 1 comprises a motor 2 equipped with a drive shaft 3 rotating about a first axis X1-X1, the reduction unit 4 rotating about a second axis X2-X2 and capable of receiving the rotation of drive shaft 3 and transmitting it to an output shaft 5 and a torque limiter.
  • the output shaft can be connected to the operating arm, which may be either a rigid articulated arm connected so as to operate the door from the side opposite that from which it is opened, or a moving pulling arm to operate the door from the side on which it is opened.
  • the operating arm may be either a rigid articulated arm connected so as to operate the door from the side opposite that from which it is opened, or a moving pulling arm to operate the door from the side on which it is opened.
  • the torque limiter comprises a toothed coupling 6, comprising two toothed surfaces 7, 8 facing each other.
  • Motor 2 is connected to reduction unit 4 through a coupling comprising a worm 9 which engages a toothed wheel 10, advantageously made of a yielding material, such as for example bronze, an aluminium alloy, a low alloy steel or a polymer material, preferably selected from the group comprising polyacetal or polyamide resins, such as for example POM or PA.
  • a yielding material such as for example bronze, an aluminium alloy, a low alloy steel or a polymer material, preferably selected from the group comprising polyacetal or polyamide resins, such as for example POM or PA.
  • Toothed wheel 10 can rotate about second axis X2-X2, which may advantageously be perpendicular to first axis X1-X1.
  • the torque limiter constructed as a coupling 6, and then a second toothed wheel 11 and a third toothed wheel 12 constituting the second and final toothed connection to reduce the rotation speed of motor 2 to values compatible with the speeds for opening and closing leaves.
  • the arm operating the swinging leaf may be mounted on output shaft 5, of one piece with third toothed wheel 12 and rotating about third axis of rotation X3-X3, which is advantageously parallel to second axis of rotation X2-X2.
  • Thrust means 14 are mounted on second rotation axis X2-X2, in addition to first and second toothed wheels 10, 11 and coupling 6, in order to keep coupling 6 normally engaged, exercising an axial force F in the direction of second axis of rotation X2-X2.
  • the axial force exerted by thrust means 14 is determined in such a way as to permit coupling 6 to disengage before the coupling between first toothed wheel 10 and worm 9 or another coupling in the drive chain transmitting the motion of toothed wheel 10 to the arm operating the door gives way.
  • toothed wheel 10 is located between thrust means 14 and disk 15 of coupling 6.
  • Thrust means 14 may advantageously comprise a spring, for example a helical spring.
  • thrust means 14 more properly comprise both the spring and toothed wheel 10.
  • the embodiment illustrated in the figures is particularly compact; in particular the use of a coupling comprising worm 9 makes it possible to achieve a high reduction in rotation speed and to use only one further coupling instead of two as in other known devices.
  • Toothed wheel 10 which engages worm 9 does not have teeth located in a radial direction, but teeth inclined with respect to axis of rotation X2-X2; worm 9 therefore also exerts a force F2 directed along second axis of rotation X2-X2 on toothed wheel 10.
  • This force is vectorially added to force F1 exerted by the spring and increases or decreases axial force F acting on coupling 6 to press the two disks 15 and 16 together, depending upon the direction of rotation.
  • toothed wheel 10 and disk 15 of coupling 6 are mounted in such a way as to move in an axial direction with respect to second axis of rotation X2-X2, at least over a distance such as to permit the two disks 15 and 16 to disengage.
  • Coupling 6 may therefore be asymmetrical, so as to compensate for this effect and provide a limiting value for the torque beyond which coupling 6 is no longer able to transmit rotation regardless of the direction of rotation in motor 2.
  • asymmetrical coupling is meant here a coupling comprising two elements pressed together, in which the ratio between the force with which the two elements are pressed together and the maximum torque which can be transmitted by the coupling also depends on the direction of the torque which is transmitted to the coupling.
  • coupling 6 would transmit a torque up to a first threshold value in one direction and up to a second threshold value, different from the first, in the opposite direction.
  • toothed surfaces 7, 8 may face each other frontally and be constructed on two disks 15, 16 located in planes which are parallel to each other and perpendicular to second axis of rotation X2-X2.
  • Toothed surfaces 7, 8, which can be seen in the figures, each comprise nine teeth 17, but a different number of teeth is possible, for example, four, six, ten, twelve, sixteen or more.
  • teeth 17 illustrated in the figures have a trapezoidal profile comprising a surface 20 parallel to the plane of disks 15, 16 located between lateral surfaces 18, 19.
  • teeth 17 are asymmetric; for example, oblique surfaces 18, 19 may have a different inclination with respect to the plane of disks 15, 16 or, in other words, with respect to second axis of rotation X2-X2.
  • the inclination of surface 18 with respect to a plane perpendicular to second axis of rotation X2-X2 is 33°, while that of surface 19 is 50°; however it is clearly conceivable that these angles may be varied, for example the first between 20° and 45° and the second between 40° and 60°, depending upon the geometry and dynamics of the coupling between worm 9 and toothed wheel 10.
  • Clearly device 1 comprises a suitable housing which may in turn comprise a portion indicated by 21 in Figure 1 which is intended for reduction unit 4 only.
  • Coupling 6 may advantageously be made of metal material, such as zinc-based alloys, for example Zama alloy.
  • helical spring part of thrust means 14 may be replaced by equivalent elements, such as for example other types of mechanical spring, or hydraulic or gas springs.
