Definitions

  • the invention relates to device for opening and closing a rotating element, in particular skylights, hatches and the like, and a skylight provided with the opening and closing device.
  • the present invention is applicable in the construction sector, and in particular can be installed on roofs and/or walls of buildings in predetermined places and/or areas, to allow the passage of natural light from the outside to the inside, and, when the skylight is open, also the passage of air between the inside and the outside.
  • skylights are generally provided with a support structure, such as for example a frame or the like.
  • the support structure is appropriately applied at a respective space or like aperture afforded through a roof or a wall of a building.
  • a suitable closing element normally transparent, to enable passage of natural light, which is suitably hinged to the support structure in order to be able to rotated about a hinge axis between a closed position and an open position.
  • these skylights are provided with a moving device which is operatively connected to the closing element in order to move the element between a closed position and an open position.
  • the moving device comprises a hydraulic actuator operatively supported by a special support structure which is engaged to opposite sides of the support structure of the skylight, and which thus significantly occupies the aperture.
  • the hydraulic actuator is in part supported by fixed support rods which substantially lie on the lie plane of the aperture and which extend centrally thereof from one side to the other of the support structure of the skylight, and in part by a series of mobile support rods, hinged together and to the fixed support rods and to the lower end of the actuator.
  • the upper end of the actuator is hinged, directly or by means of suitable connecting frames, to the closing element.
  • the command means normally used for operating the hydraulic actuator can be associated to suitable safety systems which sense risks by monitoring significant parameters in the building, such as for example the temperature.
  • skylights are not free of drawbacks and can be improved in various ways, mainly in relation to the obstruction of the light by the moving device, as the light which serves not only to illuminate the building but also enables aeration thereof, especially in emergency situations such as fire or the like, in which one or more escape routes must be provided for smoke and/or noxious fumes.
  • the particularly unwieldy structure of the known moving devices for skylights constitutes a limitation to their use.
  • the normally-used linear actuators tend to project laterally with respect to the shape of the aperture of the skylight, the skylight cannot be positioned close to walls which are perpendicular to the lie plane of the aperture.
  • the aim of the present invention is to resolve the problems encountered in the prior art.
  • an aim of the present invention is to reduce the size of the moving devices associated to the skylights.
  • a further aim of the present invention is to reduce the obstruction of the aperture at present necessary for skylights.
  • a further aim of the invention is to provide a moving device which is able to move the respective closing element without any fatigue.
  • the technical objective and the set aim are substantially attained by a moving device for rotatably closing and opening, in particular skylights, hatches and the like, and a skylight provided with the moving device as described in the appended claims.
  • 1 denotes in its entirety a moving device for rotatably-opening closing elements, in particular skylights, hatches and the like.
  • the above-mentioned device 1 is operatively associated to a skylight 2 which comprises a support structure 3 which is applicable to an aperture (not illustrated) afforded in a building structure (not illustrated), such as a roof of a shed, a storehouse, a workshop and/or any other structure requiring the presence of points of illumination and aeration.
  • the support structure 3 is advantageously the same shape as the aperture to which the skylight 2 is to be applied.
  • the support structure 3 exhibits a substantially square shape. However, it could be of any other shape that can be correctly installed in a particular aperture.
  • the skylight 2 is provided with a closing element 4 which is suitably hinged to the support structure 3, preferably along a side 3a of the frame thereof.
  • the closing element 4 is connected rotatingly to the support structure 3, about a hinge axis X. Consequently the closing element 4 is rotatable with respect to the corresponding aperture in the building to which the skylight 2 is engaged.
  • the closing element 4 is rotatable between a closed position ( figure 2 ), in which the aperture and the support structure 3 are closed by the closing element 4, and an open position ( figure 3 ), in which the hole and the support structure 3 are disengaged from the closing element 4 and are therefore open.
  • the closing element 4 exhibits a substantially cupola shape.
  • the closing element 4 exhibits a convex external surface 4a which faces outwards when the closing element 4 is in the closed position, and a concave internal surface which faces the opposite side with respect to the external surface 4a.
  • the closing element 4 is preferably made of a substantially transparent material which allows passage of light from the outside towards the inside.
  • both the transparency and the shape of the closing element 4 are characteristics that can change according to the needs and aims the skylight is intended for.
  • the moving device 1 is operatively associated to the closing element 2 to rotate the closing element 2 between the closed position and the open position.
  • the device 1 advantageously comprises at least an actuator 5, preferably hydraulic, which is fixable to the support structure 3 of the skylight 2.
  • the actuator 5 is fixed to the support structure 3 of the skylight 2 by means of a fixing structure 6 which exhibits an attachment plate 6a and a support ring 6b developing projectingly from the attachment plate 6a.
  • the support ring 6b preferably exhibits two halves which can be reciprocally distanced or neared to envelop and retain at least a portion of the actuator 5.
  • Both the plate 6a and the halves of the support ring 6b advantageously exhibit one or more holes 6c for engaging respective threaded elements (not illustrated as of known type) which enable the plate 6a to be fixed to the support structure 3 and the reciprocal engaging of the halves of the support ring 6b about the actuator 5.
  • the actuator 5 prevalently develops along an arched trajectory Y, so that the movement thereof from the retracted position ( figure 2 ) to the extended position ( figures 1 and 3 ) follows a curved trajectory.
  • the curved trajectory of the actuator 5 is advantageously substantially parallel to the trajectory of each point of the closing element 4 during the rotation thereof from the closed position to the open position.
  • the curved trajectory of the actuator 5 is parallel to the trajectory which each point of the closing element 4 performs during the rotation thereof.
  • the actuator 5 overall exhibits a telescopic structure which can extend and retract along the above-mentioned curved trajectory.
  • the actuator 5 comprises a plurality of arched segments 7, which are slidably and consecutively guided one on another. Each segment 7 exhibits a longitudinal development which is substantially parallel to the longitudinal development of the other segments 7.
  • One of the segments, preferably the base segment 7a, is retained by the above-mentioned support ring 6b so that it is engaged to the support structure 3 of the skylight 2.
  • the actuator includes at least a segment 7b which is directly or indirectly engaged to the closing element 4, preferably at the internal surface 4b thereof.
  • the base segment 7a remains fixed to the fixed structure 6 and to the support structure 3, while the other segments 7b are mobile along the curved trajectory.
  • the actuator 5 comprises three mobile segments 7b which are slidable and hermetically engaged to one another. Note however that the number of mobile segments 7b can vary according to the size of each component constituting the skylight 2, without limiting the invention to a predetermined number of segments 7.
  • each mobile segment 7b In order to enable each mobile segment 7b to slide on a further mobile segment 7b and/or the base segment 7a, the mobile segments 7b each exhibit a transversal section which is smaller than the transversal segment 7b preceding it, and greater than the transversal section of the mobile segment following it.
  • each mobile segment 7b is inserted sealedly in the segment which precedes it, when the moving device 1 is in the retracted position.
  • the transversal section of the actuator 5 decreases, segment 7 by segment 7, starting from the base segment 7a and up to the closing element 4, when the moving device 1 is in the extended position thereof.
  • Each segment 7 further exhibits a hollow body which, apart from being able to axially insertingly receive the consecutive mobile segment 7b, is advantageously in fluid communication with the mobile segment 7b in order to enable a retraction or extension of the actuator which contemporaneously interests all of the segments 7 thereof.
  • the base segment 7a is in turn in communication with a supply source 8 ( figure 4 ) of an actuating fluid of known type.
  • the supply source 8 can be of any known type which is able to provide the actuator 5 with the activation fluid at the necessary pressure for the segments 7 to slide with respect to one another between the retracted position and the extended position.
  • the device 1 is advantageously provided with an activation organ 9 which is operatively associated to the supply source 8 of the actuation fluid to move the actuator as described above following an activation command which can be an electric signal coming from a control switch, manually activatable from inside the building, or it can come from an automatic activation system which intervenes in special conditions, such as for example emergency situations.
  • an activation organ 9 which is operatively associated to the supply source 8 of the actuation fluid to move the actuator as described above following an activation command which can be an electric signal coming from a control switch, manually activatable from inside the building, or it can come from an automatic activation system which intervenes in special conditions, such as for example emergency situations.
  • the activation organ 9 is preferably a safety organ suitably provided with means for detecting 10 which can detect a predetermined activation situation in order to move the actuator 5.
  • the means for detecting 10 comprise at least a heat sensor 11 which is sensitive to changes in temperature.
  • the heat detector 4 exhibits a structure which at a predetermined temperature gives way, consequently freeing-up a blocking system 12 which retains a cutting element 13 in a retracted position.
  • a precompressed helix spring engaged to the cutting element 13 overcomes the opposition of the blocking system 12 and displaces the cutting element 13 towards a tank 14 containing a pressurised fluid, preferably a gas, such as for example carbon dioxide.
  • the cutting element 13 cuts an opening through a sealed mouth 15 of the tank 14, causing the exit of the fluid, which, through a system of channels and/or conduits, reaches the actuator 5, displacing it from the retracted position to the extended position.
  • This type of safety system advantageously enables automatic opening of the skylight 2 during a fire, offering an escape route to combustion fumes generated internally of a closed place.
  • the safety system proposed herein can be made differently from how it is described herein.
  • the skylight could even be provided with different safety devices from those used for reacting to a fire, in cases where there might be different primary risks.
  • the skylights 2 and/or the moving devices 1 associated thereto could be provided with more than one security system, which could ensure the opening of the skylight in various emergency situations.
  • the present invention solves the problems encountered in the prior art and attains the set aims.
  • the moving device of the present invention is fixed to the support structure of the closing elements by a simple structure of limited size. Consequently the device 1 does not significantly obstruct the aperture in the building the skylight is associated to, and therefore does not block passage of air between the inside and the outside of the building.
  • the special arched structure of the actuator of the device enables application of the skylight 2 also close to walls that are perpendicular to the lie plane of the passage hole, as the actuator is always contained internally of the maximum space occupied by the hole on the lie plane thereof.
  • the arched structure of the actuator 5 enables it to reach maximum extension via a curved extension trajectory, without its projecting from the skylight beyond the confines of the hole the skylight is fixed in.
  • the arched structure of the actuator enables it to operate almost always in transversal directions to the force of gravity, thus preventing directly-opposing situations with regard thereto. This means that the moving device is less subject to fatigue stress with respect to linear-type devices during opening and/or closing operations.
