Definitions

  • the present invention relates to an apparatus for the automated actuation of windows and doors.
  • One of these apparatuses is provided with a gear motor having, at its output side, a driven shaft equipped with appropriated transmission organs able to interact, in the opening and closing operations, with a movable closure structure such as, for instance, a wing, a gate, a door, etc.
  • the subject apparatus is constituted by a linear actuator and comprises an electric motor whose rotating shaft, thanks to a connection which can comprise, for instance, a series of cascaded gears to vary the transmission ratio, moves a driven shaft keyed onto a pinion which in turn meshes with a rack associated, at the free end, to the structure to be actuated.
  • This apparatus can be used, for instance, to actuate, in opening and closure, tilting wings for industrial sheds, greenhouses, etc., which can be positioned at a considerable height from the ground.
  • This irreversibility function is necessary to prevent the window(s) or door(s) from closing and, thus, to allow a safe aeration with the evacuation of the fumes outside the space.
  • the aim of the present invention therefore is to enhance traditional apparatuses for the automated actuation of windows and doors used in closed spaces with the function, also, of locking in the open position in the case, for instance, of a fire in the space; this through a structural variation of the apparatus that is extremely simple, economical, and with few variants in the constructive architecture of the traditional apparatus which, however, at the same time is always safe and reliable both under normal operating conditions and in emergencies.
  • the specified aim is substantially achieved by an apparatus for the automated actuation of windows and doors comprising motorising unit connected, through a kinematic motion transmission set, to means for actuating a closure element, which means move said closure element between two extreme positions, respectively open and closed; the apparatus further comprises means for the irreversible locking of the actuation of the closure element in the open position, located in proximity to and acting on the kinematic motion transmission set, when a predetermined ambient temperature is exceeded in proximity to the closure element.
  • the subject apparatus is used for the automated actuation of windows and doors, such as doors, wing and/or swivelling windows etc.
  • the apparatus 1 comprises a motorising unit 2 connected, by means of a kinematic motion transmission set 3, to means 4 for the actuation of a closure element, not shown in the accompanying figures, as it is of a known kind (i.e. a wing of a window, a door, etc.), and is not strictly part of the invention.
  • actuation means 4 move the closure element between two extreme positions, respectively for the closure and opening of the space or compartment whereto they are destined.
  • the latter is of the so-called linear type, with the motorising unit 2 constituted by an electric gear motor 20 actuating a series of cascaded kinematic mechanisms, to vary the transmission ratio, comprised in the aforementioned kinematic set 3.
  • Both the gear ratio 20, and the kinematic set 3 are housed and supported inside a box body or case 12.
  • the gear motor 20 actuates a pulley 21, by means of a related belt 22; the pulley 21 is, in turn, keyed onto a pinion 23 enmeshed with a first gear wheel 24 provided with a related first pinion 25 able to transmit the motion coming from the gear motor 20 to a second gear wheel 8, intermediate in the set of motion transmission kinematic mechanisms.
  • This second gear wheel 8 is provided with a related second pinion 26 enmeshed in a third gear wheel 27 fitted with a corresponding third pinion 28 housed inside a tubular element 29 for protecting the aforesaid actuation means 4.
  • the actuation means 4 comprise a track 30 connected, at it free end, with the aforesaid closure element; the rack 30 is enmeshed on the aforementioned third pinion 28, in such a way as to be able to move linearly in the two directions (see arrow F in Figure 1) and allow the opening and closing of the closure element through the motion transferred from the gear motor 20 to the third pinion 28 through the kinematic mechanisms described above.
  • the apparatus 1 summarily described above comprises means 5 for the irreversible locking of the actuation of the closure element in the aforementioned open position, which are situated in proximity to and act on the aforementioned motion transmission kinematic set 3, in correspondence with a temperature rise above a predetermined ambient temperature in proximity to the closure element.
  • the irreversible locking means 5 can comprise, in terms of generic solutions, at least an element 6 able to become deformed when a predetermined ambient temperature is exceeded.
  • the irreversible locking means 5 can comprise an elastic element 6 held, in a position not interfering with the kinematic set 3, by an element 7 able to be elastically deformed when a predetermined ambient temperature is exceeded, in such a way as to allow the aforementioned elastic element 6 to change its position at least until it interferes with the kinematic set 3 to obtain an interruption of the transmission of motion.
  • the aforementioned irreversible locking means 5 are positioned and act on the aforementioned second gear wheel 8 to block the return motion to the closed position.
  • the irreversible locking means 5 comprise a "U" shaped elastic element 6 rotated on a side, which is positioned (see also Figure 2) facing a surface 8a of the second gear wheel 8.
  • the second gear wheel 8 is provided, on the aforesaid surface 8a, with at least a groove 9 able to be oriented facing the elastic element 6 in correspondence with the attainment of the aforementioned open position.
  • the elastic element 6 is held, in a position removed from and not interfering with the second gear wheel 8, by a ring 10 able to be deformed, i.e. to expand when a predefined threshold of the temperature of the surrounding space is exceeded, thereby allowing an approaching motion (see arrow F1 in Figure 2) of a first wing 11 of the elastic element 6 towards the second gear wheel 8 until it engages the aforesaid groove 9 thereby obtaining an irreversible locking of the actuation of the apparatus 1.
  • the "U" shaped elastic element 6 is associated, with its second wing 13, to a base wall 12a of the aforementioned case 12 through related fastening means 14, constituted by a screw, in such a way as to be positioned underneath the aforementioned second gear wheel 8 when the mounting of the apparatus 1 is complete.
  • the base wall 12a of the case 12 is also provided with a recess 15 for the positioning and stabilisation of a portion of the aforesaid deformable ring 10 that holds the "U" shaped elastic element 6: this allows for a stable and planar position of the second wing 13 of the "U" shaped elastic element 6 on the base 12a of the case 12.
  • the aforementioned second gear wheel 8 can be provided with multiple grooves 9, at equal angular distances from each other, on its own surface 8a facing the "U" shaped elastic element 6: this is to allow a possible locking in an even partially open position of the closure element.
  • none of these grooves 9 may be able to face the "U" shaped elastic element 6 in correspondence with the completely closed position of the closure element.
  • the ring 10 is made of plastic material and it is preferably deformable when a temperature of about 100°C is reached. This deformability can lead, subsequently and under the thrust of the first wing 11 of the "U" shaped elastic element 6, to a complete rupture of the ring 10.
  • the deformability threshold to be reached can be varied, by diversifying the type of material whereof the ring 10 is made, according to the needs and the type of environment in which the closure element is mounted.
  • An apparatus thus structured functions in the following manner, for instance if mounted on a wing of a transom window in an industrial shed.
  • the ring 10 upon the occurrence of particular conditions in the shed, such as an excessive temperature rise, due to a fire, the ring 10, becoming deformed by effect of the high temperature, causes the first wing 11 of the elastic element 6 to lift until it breaks the ring 10 and engages one of the grooves 9 of the second gear wheel 8: in this way the possible activation of the motorisation 20 to return the wing to the closed position is contrasted by the block of the second gear wheel 8, keeping the wing open and allowing the evacuation of the fumes generated by the fire inside the shed.
  • the apparatus thus obtained therefore achieves the specified aims thanks to the use of a simple and economical locking assembly, which is extremely precise in the function to be performed avoiding the closure of the closure element under emergency conditions.
  • the elastic element and the ring are housed inside the case of the apparatus with no need to construct particular compartment inside the case itself, so there is no need to change the traditional constructive architecture of the apparatus.
