Definitions

  • the invention concerns an electric gearmotor for metal rolling gates counter-weighed by springs, equipped with a mechanical irreversibility device fitted between the gearmotor and the motor according to the introductory part of claim 1.
  • said irreversibility mechanism is fitted at one end of the driving shaft which performs a short axial stroke thanks to which it is possible to move away and uncouple the mechanism from the gearmotor.
  • the gearmotor in question is mounted above all on rolling gates counter-weighed by springs which, as such, may also be lifted manually in that the weight of the rolling gate is balanced by a series of springs which wind during the downward stroke of the gate and unwind during the upward stroke.
  • the irreversibility of the gearmotor prevents the rolling gate from being lifted manually by burglars when lowered; in this sense the irreversibility of the gearmotor offers further security against burglary attempts with respect to the locks or keys generally used on compensated rolling gates.
  • the start-up of the motor entails the automatic deactivation, even if not instantaneous, of the electric brake, which is operated by a spring and automatically and instantaneously stops the driving shaft as soon as the electric supply is cut off.
  • gearmotors are always fitted with a device for the manual release of the electric brake, for emergency situations, when it is necessary to lift or lower the rolling gate even in the case of temporary power failure of the electric plant or the mains.
  • Said manual release device is generally operated by pulling a metal cable attached to the electric brake.
  • This free-wheel is combined to means which drive an electric contact set to invert the rolling way of said shaft during the gate descent, as soon as said free-wheel starts working.
  • This gearmotor does not provide for means which allow the temporary interruption of the connection between the free-wheel and the gearmotor's shaft.
  • the purpose of this invention is to design a new gearmotor model for metal rolling gates, counter-weighed by springs, whose movement irreversibility is provided by a completely mechanical device in which the emergency cable that excludes said device is attached to one end of the driving shaft.
  • said mechanical irreversibility device offers two main advantages: the first is an economical saving in that the mechanical device is less expensive than the above electric brake; the second is an operating advantage in that said device can instantaneously stop the driving shaft in the case of a power failure, contrary to the electric brake whose action is not instantaneous.
  • the gearmotor according to the invention uses a mechanical irreversibility device which is commonly known which permits the drive of the rotary motion only if said motion is introduced on one of the two elements of the drive which is on the other hand prevented in the reverse direction.
  • Said irreversibility device is mounted at the end of the driving shaft immediately in front of the gearmotor which is connected to the irreversibility device by a mobile front connecting coupling.
  • the driving shaft is supported so as to perform a backward axial stroke in order to release the irreversibility device from the gearmotor, in case of emergency in order to allow the manual movement of the rolling gate.
  • the backward stroke of the driving shaft can be activated by a special emergency cable attached to the driving shaft on the opposite end with respect to the end on which the irreversibility device is mounted.
  • the gearmotor according to the invention consists of a conventional electric motor (1) and a gearmotor (2) between which is fitted an irreversibility device (3) consisting of two elements (3a and 3b) coupled so as to allow transmission of the motion only in one direction.
  • the other element (3b) of this device (3) is provided with teeth (3c) which permit a front connection type coupling between the device (3) and the gearmotor (2).
  • the shaft (1a) of the motor (1) is supported so as to perform a short axial stroke (d) which makes it possible to engage and disengage the device (3) and the gearmotor (2) which are coupled by means of a spring (4) fitted on the shaft (1a) and pressing against the element (3a) keyed on the shaft in order to push and keep the device (3) pressed against the gearmotor (2).
  • a fork bracket (5), sliding within a housing (6) and fixed to the motor (1) casing, is hooked at the end of the shaft (1a) opposite to the end on which the device (3) is keyed.
  • the emergency cable (7) is in turn attached to said bracket (5); it being provided that by pulling the cable (7) it is possible to slide back the shaft (1a) in order to disengage the device (3) from the gearmotor (2). Naturally said cable (7) should be pulled with enough force to overcome the resistance of the spring (4) which presses against the above element (3a) - belonging to the irreversibility device (3) - keyed on shaft (1a).
