Definitions

  • the invention relates generally to a tubular actuator for a roller shutter (e.g., such as awnings or blinds), in particular to a actuator equipped with a device to facilitate the connection between an electrical connector and the gearmotor.
  • a roller shutter e.g., such as awnings or blinds
  • a device to facilitate the connection between an electrical connector and the gearmotor e.g., awnings or blinds
  • tubular gearmotors which are equipped with an electric motor and installed inside the tube around which the shutter is wound,. See, for example, EP 2 397 647 B1 .
  • an external connector 10 equipped with a head 12 to be inserted inside an axial cavity 14 made in the tubular body 18 of the gearmotor, is used.
  • the head 12 has a tab 16 with a protrusion that snaps into an undercut of the cavity 14 to lock the head 12 in place inside the gearmotor.
  • the cavity 14 is very deep, due to construction issues, which leads to obvious inconvenience when connecting the head 12 and especially during release, when one wants to disconnect the connector 10 from the gearmotor.
  • the operation is basically done blindly, levering the protrusion by using a screwdriver, see Figure 1 , to undo the engagement between the protrusion and the undercut.
  • the main object of the present invention is to improve the state of the art.
  • Another object is to avoid the above inconveniences by facilitating the connection and disconnection of the connector 10.
  • roller shutter actuator e.g. such as blinds or awnings
  • a roller shutter winding drum comprising:
  • the pressing/actuating member makes it possible to detach the connector from the gearmotor without the use of any tools, being enough for the purpose to simply push the pressing member toward the head from the outside of the gearmotor.
  • the pressing/actuating member there is the advantage of greatly speeding up maintenance or installation of the gearmotor.
  • the pressing/actuating member is particularly advantageous because, as it does not require permanent connections to the head, it is easy to apply and a displacement of the pressing/actuating member relative to the head is sufficient to move the movable member.
  • the actuating member is connected to the head and/or the movable member, e.g. simply with a cable or a rigid arm.
  • the tubular body has a longitudinal axis parallel or coincident, when installation is completed, with the rotation axis of the drum.
  • said cavity is a blind tunnel.
  • the axial cavity or the blind tunnel has a depth that develops parallel to the longitudinal axis of the tubular body.
  • the pressing/actuating member is conformed to contain or embrace the electrical cable while remaining free to slide relatively to the cable along the direction of the cable length. It should be noted that another advantage of this configuration is the reduction of overall dimensions, because the volume of the cable is "absorbed" into the pressing/actuating member. Another advantage of this configuration is that the cable acts as a guide for the pressing/actuating member.
  • the pressing/actuating member comprises a superficial concavity or channel for containing or embracing the electrical cable, the superficial concavity or channel extending linearly between two opposite ends of the pressing/actuating member, wherein one of such ends is configured to abut - in use - against the head.
  • the central portion of the pressing/actuating member that is conformed to contain or embrace the electrical cable, for greater stability and symmetry.
  • An additional advantage of the pressing/actuating member anchored to the cable and abutting against the connector head is that the pressing/actuating member remains always available to the operator for the operations of replacement and/or maintenance of the tubular motor. For example, the operator does not always have at hand the screwdriver.
  • the pressing member comprises a protruding tooth and/or an inclined plane, configured to contact and push the movable member of the head as a result of a displacement of the pressing member toward the head.
  • the protruding tooth and/or inclined plane is placed at the end of the pressing member which is configured to abut - in use - against the head.
  • the movable member is a flexible tab protruding cantilevered from the head, but it could be something else, e.g. a retractable pin.
  • the pressing/actuating member is configured to move the movable member along a direction orthogonal to the axis of the cavity or tunnel, either toward the center of the head or toward the outside of the head.
  • the pressing/actuating member and the head are configured to be applied next to each other along a common axis, so the pressing/actuating member and the head can be mounted in a row behind each other (simplicity of mutual application and to the tubular body).
  • the common axis is parallel to the longitudinal axis of the tubular body.
  • one end of the pressing/actuating member comprises two cross-section expansions, which in particular are placed on opposite sides of the linear concavity, respectively.
  • the cross-section expansions are configured to snugly plug the inlet of the cavity into the tubular body. This prevents the entry of dirt, and mechanical play between the parts is nulled.
  • the pressing/actuating member is configured to be attached to the cable and abutting against the head, so that the assembly of the pressing/actuating member and the head are insertable inside the axial cavity.
  • the relative dimensions of the cavity, the head, and the pressing/actuating member are such that the two cross-section expansions go flush with the outer profile of the tubular body when the pressing/actuating member and head assembly are inserted. Then the cross-section expansions remain accessible on the outer surface of the tubular body, and an operator can conveniently push them in to activate the pressing member and detach the head from the axial cavity.
  • Another aspect of the invention is a method for disconnecting an actuator for a roller shutter (e.g. such as blinds or awnings) from an external electrical connector, the actuator being structured to be installed inside a winding drum for the shutter, and comprising:
  • a gearmotor 30 for roller shutters comprises a tubular body 32 that has a longitudinal X axis and at one end 36 is equipped with a blind tunnel 34 whose depth develops parallel to the X axis.
  • An electric motor (not shown) is installed in the tubular body 32 to rotate about the X axis a drum on which the roller shutter is wound.
  • the bottom of the tunnel 34 has electrical terminals (not shown) to electrically power the gearmotor.
  • the power supply is carried by an external connector 40 equipped with a head 42 that comprises electrical terminals that can be coupled to those inside the tunnel 34.
  • An electrical cable 38 extends from the head 42 to the power supply mains.
  • the head 42 also comprises a movable member 44 (like a flexible tab) that can engage its tooth 46 in a corresponding cavity or inner undercut of the tunnel 34, so that the head 42 can be locked in place by interference inside the tunnel 34.
  • a movable member 44 like a flexible tab
  • the connector 40 also comprises a pressing member 50 separate from the head 42 but approachable to it.
  • the pressing member 50 is conformed to contain or embrace the electrical cable 38 thanks to a central surface concavity 52 ( fig. 3 ) that extends linearly between two opposite ends 54, 56 of the pressing member 50: one end 54 is configured to abut - in use - against the head 42, the other end 56 remains free.
  • the pressing member 50 comprises at the end 54 a protruding tooth 58, which is configured, e.g. via an inclined plane converging toward the center of the member 50, to contact and push the movable member 44. Then, when the pressing member 50 and the head 42 are applied to each other along a common axis by making the end 54 abut against one side of the head 42, the displacement of the tooth 58 toward the head 42 (arrow F1) causes the movable member 44 to flex toward the center of the head 42 (arrow F2).
  • the end 56 of the pressing member 50 comprises two cross-section expansions 60 placed on opposite sides of the linear concavity 52, respectively.
  • the cross-section expansions are configured to snugly plug the entrance of the tunnel 34.
  • the pressing member 50 is applied to the cable 38 and abutted to the head 42, so that the tooth 58 rests on the free end of the movable member 44.
  • the resulting assembly is insertable - and inserted - inside the tunnel 34. After such insertion, the electrical contacts of the head 42 are connected to those inside the tunnel 34, and the two cross-section expansions 60 are brought flush with the outer profile of tubular body 32. Thus, the cross-section expansions 60 remain accessible on the outer surface of the tubular body 32.
  • An operator can push the cross-section expansions 60 to activate the pressing member 50: the tooth 58 moves along the F1 direction, pushes the movable member 44 along the F2 direction, the tooth 44 disengages from the walls of the tunnel 34, and the head 42 (and the pressing member 50) can then be extracted from the tunnel 34.
  • the convenience of maneuvering allowed by the pressure member 50 is evident.
  • the connector 40 can be detached from the gearmotor without the aid of any tools and very quickly.
