Definitions

  • the present invention falls within the technical field of automatic actuating devices for rolling blinds or rolling doors of the type used, for example, in garages, shops or some dwellings. More particularly, the present invention describes a device the object of which is the automatic actuation of doors or blinds in a more silent manner with respect to known devices, and which, in the event of locking, can be manually lifted without having to overcome the resistance of the automatic actuating motor.
  • the devices known in the state of the art have the drawback that, in the event of failure or locking of the actuating mechanism, they must be manually lifted and the force exerted must also overcome the force of the resistance of the automatic actuating motor. Therefore, depending on the size of the door, a single person may not be able to lift and open it.
  • the present invention aims to solve some of the problems mentioned in the state of the art. More particularly, the present invention describes an automatic actuating device for a rolling door or a rolling blind intended to be rolled up on an outer portion of a wheel comprising:
  • the present invention aims to incorporate an unlocking mechanism to the device described above that enables the actuating force of the motor to be disengaged with respect to the outer portion of the wheel that moves the rolling blind or rolling door, thus enabling, in the event of locking or breakdown, the door to be manually moved without having to overcome the force of the resistance of the motor.
  • said unlocking mechanism is preferably arranged on the inside of a container that is rigidly attached to the inner portion of the wheel, wherein the unlocking mechanism comprises:
  • the device comprises, for example, an electromagnetic actuator, or a cable attached to said tab so that when the tab is rotated, it drags the mobile cam through the perimeter ramp moving longitudinally and in turn moving the transmission gear wheel that is attached to the mobile cam, and, consequently, removing the pins from the holes and disengaging the force of the motor from the outer portion of the wheel wherein the door or blind is rolled up and therefore opens or closes it.
  • the device with the technical features described enables the door to be lifted manually in the event of a breakdown, without having to overcome the resistance of the motor.
  • the device can have a spring adapted to perform a thrust force which, once the thrust of the actuator element stops, said thrust force enables the part and the mobile cam to move longitudinally, causing it to rotate and therefore causing the pins to penetrate inside the holes again.
  • the force of the actuator or actuator element will then have to overcome the force of the spring, and once it stops, said spring makes it possible to return to the initial position with the pins inside the holes.
  • the device with the technical elements and with the interactions between elements of the mechanism described above has been shown to make less noise than known commercial devices. Specifically, a maximum acoustic emission of between 44 and 55 dB has been measured.
  • the mobile cam in a locked position with the pins inside the holes fits into the one or more perimeter openings of the fixed cam, both cams forming a cylindrical outer configuration.
  • the fixed cam is provided with two perimeter openings so that when the fixed cam travels along the ramp, another portion of the mobile cam can abut at the second rear opening defining a rear abutment.
  • the motor is a direct current motor and as it is mounted in the manner described above, it has been successfully used with rolling doors weighing up to 100 Kg with direct current motors of between 30 and 100W, without observing a noticeable heating with very intensive use.
  • Figure 1 shows an example of a wheel (2) for a rolling door or a rolling blind intended to be rolled up on the outer portion (16) of said wheel (2).
  • the wheel (2) comprises an internal disc (15) which comprises through holes (4) and is solidly attached to the outer portion (16).
  • the wheel further comprises an inner portion (17) that houses said disc (15) in a rotatable manner, the inner portion (17) having a relative rotational movement with respect to the disc (15).
  • wheels (2) of this type are used and a shaft is longitudinally coupled to the disc (15), wherein said shaft is actuated by a motor longitudinally mounted therein.
  • the shaft of the motor rotates the disc (15) which has an internal pinion that in turn meshes with a gear wheel mounted on the inside of the outer portion (16), such that the motor rotates the disc (15) that meshes with the gear wheel that rotates the outer portion (16) and therefore the blind or door rolled up therein.
  • the disc (15) has through holes (15) to lighten the weight.
  • Figure 2 shows an exploded view of a preferred embodiment of the present invention wherein it illustrates the automatic actuating device comprising a motor (18) perpendicularly mounted with respect to a transmission gear wheel (5) by means of a worm screw-gear wheel mechanism (20).
  • the device comprises an unlocking mechanism (7) arranged on the inside of a container (8) that is rigidly attached to the inner portion of the wheel (2).
  • the unlocking mechanism (7) comprises a fixed cam (9) operatively attached to the inner portion (17), said fixed cam (9) comprises a perimeter opening (11) that defines a perimeter ramp, and a mobile cam (10) attached to the transmission gear wheel (5) wherein said mobile cam (10) has a portion adapted to fit into the at least one perimeter opening (11) of the fixed cam (9) and is attached to a part (12) which comprises a tab (13) that penetrates and protrudes through a window (14) of the container (8), such that, when actuating the motor (18) with the pins (6) housed inside the through holes (4), the transmission gear wheel (5) rotates the mobile cam (10) which in turn pushes the fixed cam (9) thus enabling the joint movement of the assembly to open or close the rolling door or rolling blind that is rolled up on the outer portion of the wheel (2),
  • the tab (13) is intended to be actuated tangentially by an actuator element that rotates the tab (13) which in turn rotates the mobile cam (10) through the ramp, consequently, causing it to move longitudinally to move the transmission gear wheel (5), thus removing the pins (6) from the holes (4).
  • the device has a spring adapted to perform a thrust force which once the thrust of the actuator element stops, said thrust force moves the part (12) and the mobile cam (10) longitudinally, causing it to rotate and therefore causing the pins (6) to penetrate inside the holes (4) again.
  • Figure 3A shows an unlocked or normal operating position with the adjoining mobile cam (10) and pushing the fixed cam (11).
  • Figure 3B shows an unlocked position with the mobile cam (10) after being moved, with the pins (6) of the transmission gear wheel (5) outside the through holes (4).
  • the wheel (2) is used with the piston-gear wheel mechanism used in the state of the art as shown in Figure 1 , and the invention describes a mounting kit to be mounted on said wheel (2), wherein the mounting kit comprises the unlocking mechanism (7), the container (8) and the motor (18) tangentially mounted to the transmission gear wheel (5) by means of a worm screw mechanism (20).
