Definitions

  • the invention relates to mechanical activating devices for doors, which can be swing doors or sliding doors.
  • the invention relates to an automatic activating device, which commands opening of the door on receiving a signal caused by a presence of a person about to pass through the door, and commands automatic reclosing of the door after a predetermined time.
  • the door rotates about a vertical axis located in proximity of one of the vertical edges thereof, and is connected by means of at least two hinges to the adjacent side of the doorway.
  • the movement of the door in the containing door-way is given by a device fixed to the wall in which the door-containing space is afforded.
  • the device exhibits a main vertical output shaft to an end of which a crank is fixed which crank moves in a horizontal plane and is connected by a connecting rod to a point of the upper edge of the door.
  • the shaft of the crank is rotated by a mechanism which comprises a driven pinion and a suitable gear reduction.
  • the pinion is generally driven by a linear actuator to which it is coupled by a rack-and-pinion coupling.
  • a gear reduction is provided between the driven pinion and the main shaft, located in cascade, which in known devices is the origin of mass and efficiency problems which grow in importance as the weight of the door to be activated increases.
  • the aim of the invention is attained by a device having the characteristics recited in the independent claim.
  • a device comprising a main shaft destined to transmit motion to the door by means of a special mechanism.
  • the shaft is supported idle in a fixed casing, and bears, inserted thereon, a freely-rotatable bush, provided with an upper pinion for input of motion, and a lower pinion for transmission of motion.
  • the lower pinion is connected to the fixed casing by means of at least a planet gear rotating on a pin which is parallel to the main shaft supported thereby, the at least a planet gear enmeshing with both the lower pinion and the bush, as well as with the internal cogging of a body fixed to the casing.
  • the figures illustrate a doorway closed by a door 2 which rotates about an axis 3 defined by coaxial pivots.
  • the activating device 4 of the invention is fixed by known means to the upper part of the doorway occupied by the door 2.
  • the device of the invention exhibits a casing 41 in which a main shaft 5 is rotatably supported, which main shaft 5 terminates inferiorly with the output shank 51.
  • crankshaft 6 is fixed to the shank 51, which shank 51 is hinged to an end of the con rod 7, which con rod 7 is in turn connected by hinging to the door 2.
  • the device 4 comprises an external casing 41 internally of which the main shaft 5, which extends up to the top of the casing 41, is supported by the bearing 42.
  • the main shaft 5 is made in differentiated sections and comprises a broad flange 52, located above the bearing 42.
  • the flange 52 supports four equidistant vertical pivots 53, on which four gearings 54 rotate idle.
  • the gearings 54 constitute the planet gears of a planetary gear unit, and enmesh on an internal cogged crown 420 fixed to the casing 41.
  • the planet gears 54 are also enmeshed with the external cogging 81 of a bush 8 mounted idle on the shaft 5, the external cogging 81 realising the lower drive-transmission pinion and functioning as the sun element of the planetary gear unit.
  • a helically-cogged pinion 82 is keyed and blocked on the bush 8, in a position overlying the external cogging 81, which helically-cogged pinion constitutes the upper drive input pinion of the mechanism of the device.
  • the pinion 82 is in turn enmeshed in the helical cogging 83 of a shaft 9 having an axis which is perpendicular to the shaft 5, and which is rotated by an electric motor denoted schematically by 10 in figure 5 .
  • the top of the shaft 5 is connected to the end of a spiral spring 11, another end of which is fixed to the cover 43 of the casing 41.
  • the spring 11 can also be left out, as will be better understood from the following.
  • the device functions as follows.
  • the electric motor 10 When the sensor, not illustrated, signals the presence of a person about to pass through the doorway, the electric motor 10 is activated by means of a first gearing realised by the helical coupling between the pinion 82 and the shaft 9, and a second gearing, realised by the coupling between the bush 8 and the planet gears 54 and the cogging 420, sets the shaft 5 in rotation which draws the door open, overcoming the resistance of the spring 11.
  • An encoder (not illustrated) applied on the shaft of the motor 10, signals the complete opening of the door.
  • the motor After a predetermined time, the motor is short-circuited to effect a brake, and the spring causes the door to close.
  • the motor is activated in an opposite direction and causes closure of the door.
  • the device of the present application can be coupled to the respective door by different means than the con rod-crankshaft coupling. It can be, for example, coupled to a sliding door by means of a rack-and-pinion coupling, with the pinion being supported by the shank 51 of the shaft 5, and the rack being fixed to the edge of the door.
