Definitions

  • the present invention relates to a motorized device for opening/closing a door or window, particularly suitable for doors or entrance doors.
  • cylinder-and-piston unit which is actuated electromechanically or hydraulically and is provided on each leaf of the door or the window to be automated.
  • the cylinder is pivoted to the respective post of the door or window and the piston is designed to slide telescopically within the respective cylinder at one end and to rotatably engage the respective leaf at the other end by means of a pivot that protrudes from the leaf.
  • each piston with respect to its cylinder in fact forces the respective leaf to perform a preset angular stroke in a corresponding direction of rotation about its own hinge, so as to respectively open or close the door or window.
  • Such devices though being currently widely used, especially for moving doors or entrance doors, have the characteristic that they are not easy to operate manually, for example if there is a power outage, since they require a specific intervention, aimed at disengaging actuation mechanisms, which almost always requires the use of a key or the actuation of a disengagement lever system.
  • the motorized devices currently used to move doors or windows can sometimes be a factor for risk of injury, since a person who happens to be nearby can involuntarily injure his hands, especially if such devices are mounted at such a height from the ground that places them within the reach of children.
  • the aim of the present invention is to provide a motorized device for opening and/or closing a door or a window that does not have the drawbacks noted above regarding the devices currently in use.
  • Another object of the present invention is to provide a device that is to be installed adjacent to the upper fixed part of the door or window (lintel of the frame), which normally cannot be reached by people and is further easily concealable, thus ensuring maximum safety during its operation, with considerable advantages from the aesthetic point of view as well.
  • a motorized device for opening/closing a door or a window comprising: a supporting frame formed by at least two lateral posts and by an upper lintel; at least one leaf mounted rotatably on said supporting frame; and a pivot or hinge for each leaf, which is suitable to rotatably support the respective leaf on said supporting frame and to rotate, during use, rigidly therewith; characterized in that it comprises articulated transmission means, which rotate rigidly with said pivot or hinge and are suitable to transmit to said leaf a rotary motion about the respective pivot or hinge, and actuation means that is kinematically connected to said articulated transmission means and is suitable to impart thereto a preset angular stroke about the pivot or hinge, so as to move the respective leaf between a closure position and at least one open position.
  • the actuation means comprises at least one reversible motor, which is mounted on the supporting frame so that it can perform angular strokes about an articulation axis that is substantially parallel to the pivot or hinge.
  • the articulated transmission means comprises: an actuation shaft, which is actuated by said reversible motor so as to receive a rotary motion for a preset number of turns in either direction of rotation; at least one female-thread element, which is mounted so that it can slide along said actuation shaft; and at least one lever, one end of which rotates rigidly with said pivot or hinge and the other end of which is articulated to said female-thread element, so as to convert the rotary motion of said actuation shaft in one direction or in the opposite direction into a corresponding angular stroke of the respective leaf about its pivot or hinge.
  • a motorized opening/closure device can be installed at a door or window 2, such as for example a door or entrance door, which is generally composed of a supporting frame 3, comprising two posts 4 and 5 and an upper lintel 6, and of a leaf 7 which is mounted rotatably on the supporting frame 3 by means of a pivot or hinge 8.
  • the hinge 8 which can lie vertically or horizontally depending on the opening/closure system to be used for the leaf 7, is designed to support the leaf 7 so as to rotate rigidly therewith, so that an angular stroke of said hinge about its own main axis x-x is matched by an angular stroke of equal breadth of the respective leaf 7.
  • the above cited figures show a door or a window 2 that has the structure of a door, with a leaf 7 articulated to the supporting frame 3 by means of a vertical hinge 8.
  • the motorized device 1 first of all comprises actuation means, which can be constituted by a reversible motor 9, which is mounted on the leaf 7 so that it can perform angular strokes with respect to a substantially vertical axis y-y (see Figure 1 and the letter A of Figure 2) and is suitable to generate a rotary motion (designated by the letter B in Figure 1) about a substantially horizontal axis z-z.
  • actuation means which can be constituted by a reversible motor 9, which is mounted on the leaf 7 so that it can perform angular strokes with respect to a substantially vertical axis y-y (see Figure 1 and the letter A of Figure 2) and is suitable to generate a rotary motion (designated by the letter B in Figure 1) about a substantially horizontal axis z-z.
  • the device 1 further comprises transmission means 10 designed to convert the rotary motion B generated by the reversible motor 9 into a corresponding angular stroke of the respective leaf 7 about its own hinge 8 (designated by the letters C' and C" in Figure 2).
  • the transmission means 10 preferably comprise an actuation shaft 12, which is actuated by the reversible motor 9 so as to receive a rotary motion B for a preset number of turns in either direction of rotation; a female-thread element 13, which is mounted so that it can slide along the actuation shaft 12; and at least one lever 14, one end 15 of which rotates rigidly with the hinge 8 of the respective leaf 7 and the other end 16 of which is articulated to the female-thread element 13.
  • the actuation shaft 12 has a helical thread 17 (see Figures 3 and 4), at least along a portion that corresponds to the stroke of the female-thread element 13, which in turn has female-thread means 18 designed to engage, during use, the helical thread 17 of the actuation shaft 12 in order to convert the rotary motion B of the actuation shaft 12 in either direction into a corresponding linear stroke, respectively an outgoing or return stroke (designated by the letters D' and D" in Figure 2), of the respective female-thread element 13 along said actuation shaft 12.
  • Figures 3 and 4 in fact show that a female-thread element 13 is preferably composed of a hollow element 19, which internally delimits a hollow portion 20 that acts as a sliding seat for the actuation shaft 12 and as a seat for the female-thread means 18.
  • the female-thread means 18 is configured so as to engage only an angular portion of the actuation shaft 12 and can be moved on command within the respective hollow portion 20 between an active position, in which it engages the actuation shaft 12, and an inactive position, in which it is retracted and disengaged with respect to said actuation shaft 12.
  • the coupling of the female-thread means 18 to the helical thread 17 of the actuation shaft 12 can be provided by way of an actuation device 21, for example of the electromagnetic type, supported by the female-thread element 13 and powered by an external electrical power source (not shown in the figures).
  • the actuation device 21 preferably comprises a supporting housing 23, which is fixed in any suitable manner to the hollow element 19 that composes the female-thread element 12; a solenoid 24, which is accommodated within the supporting housing 23 with a longitudinal axis j-j that lies transversely to the actuation shaft 12; and a keeper element 25, which is arranged inside the respective solenoid 24 and has an end that is mechanically connected to the female-thread means 18.
  • a return means 26 is provided between the keeper element 25 and the female-thread means 18 and comprises, for example, a spring suitable to apply a constant force for spacing the female-thread means 18 from the respective actuation shaft 12, so as to ensure that when the solenoid 24 is not energized the female-thread means 18 is disengaged from the actuation shaft 12.
  • the female-thread means 18 move toward the actuation shaft 12 by supplying the solenoid 24 with a current having a predefined orientation and intensity.
  • the current that flows through the solenoid 24 in fact induces therein a magnetic field suitable to act on the keeper element 25 with a force whose direction coincides with the axis j-j of the solenoid 24 and whose orientation is opposite to the orientation of the elastic force applied by the spring 26.
  • a control unit (not shown in the figures) makes the electric current source supply the solenoid 24 with a preset orientation through its turns 22 that induces inside it a magnetic field directed toward the actuation shaft 12. Accordingly, a force which is opposite to, and greater than, the return force of the spring 26 is applied to the keeper element 25 affected by said induced magnetic field, so as to make it move toward the axis z-z, until the female-thread means 18 engages the helical thread 17 of the actuation shaft 12.
  • the control unit drives the motor 9 so as to turn the actuation shaft 12 about its own axis z-z, so as to make the female-thread element 13 perform a stroke D' along the axis z-z, the length of the stroke depending on the number of turns of the actuation shaft 12, such number being in turn controlled for example by an encoder (not shown in the figure) associated with the motor 9.
  • control unit interrupts the supply of current to the solenoid 24 and thus removes the electromagnetic force that ensures, during use, the mutual engagement of the female-thread means 18 and the actuation shaft 12.
  • return spring 26 in fact forces the female-thread means 18 to move away from the axis z-z and disengage from the actuation shaft 12.
  • the control unit After a preset time interval, the control unit starts the step C" for closing the leaf 7, energizing the solenoid 24 so as to return the female-thread means 18 to the active position, i.e., into the condition in which it engages the helical thread 17 of the actuation shaft 12, and driving the motor 9 so as to turn the actuation shaft 12 in reverse with respect to the opening step.
  • the female-thread element 13 is thus forced to perform a movement D" toward the motor 9, such movement being matched by an angular return stroke E" of the lever 14 whose breadth is equal to the outgoing stroke E' in order to return the respective leaf 7 to the closed position.
  • the actuation device 21 is not provided with the return spring 26, in which case it has a rigid and direct coupling between the solenoid 24 and the female-thread means 18.
  • the solenoid 24, depending on the direction in which the current flows through its turns 22, generates internally a magnetic field that is suitable to apply to the respective keeper element 25 a force meant to move the keeper element 25 respectively toward or away from the actuation shaft 12, in order to respectively produce the engagement or disengagement of the female-thread means 18 with respect to the actuation shaft 12.
  • the actuation device 21 requires an auxiliary power source (not shown in the figures) capable of supplying at least the current required to disengage the female-thread means 18 from the actuation shaft 12 in order to allow the free sliding of said shaft within the hollow portion 20 of the female-thread element 13 and therefore allow the manual opening and/or closure of the respective leaf 7.
  • a device 1 can comprise, as actuation means, a linear actuator 30 composed of, for example, a cylinder-and-piston unit 31 having a cylinder 32 mounted on the lintel 6 of the supporting frame 3 so that it is free to perform angular strokes about an articulation axis y-y, which is substantially parallel to the hinge 8 of the respective leaf 7, and a piston 34, which is supported by the cylinder 32 and is suitable to slide telescopically, on command, within cylinder 32, so as to perform outgoing and return strokes (designated by the letter F) on a plane that is substantially perpendicular to the articulation axis y-y.
  • a linear actuator 30 composed of, for example, a cylinder-and-piston unit 31 having a cylinder 32 mounted on the lintel 6 of the supporting frame 3 so that it is free to perform angular strokes about an articulation axis y-y, which is substantially parallel to the hinge 8 of the respective leaf 7, and a piston
  • the piston 34 is articulated, at its free end 35, to the end 16 of the lever 14, which in turn rotates rigidly, at its end 15, with the hinge 8 of the respective leaf 7, as in the preceding configuration.
  • the device 1 further comprises a control unit (not shown in the figure) which is suitable to drive, during use, the cylinder-and-piston unit 31 in order to move the piston 34 along its main axis z-z between an initial position and a final position, so as to force the lever 14, and therefore the respective leaf 7, by means of the hinge 8, to perform a corresponding angular stroke whose predefined breadth depends on the stroke F that the piston 34 is made to perform.

  • the above-described embodiment of the device 1 can be provided with clutch means 48 in order to allow the disengagement of the device 1 from the respective leaf 7, so as to allow manual opening and/or closure of said leaf.
  • the clutch means 48 which can be constituted for example by an electric clutch, is preferably mounted at the coupling between the lever 14 and the hinge 8.
  • the control unit of the device 1 drives the electric clutch 48, by means of which it is possible to make the lever 14 rotate rigidly with the hinge 8 and thus automatically open or close the leaf 7.
