Description
- The present invention relates to a skylight of the type specified in the preamble to the first claim.
- In particular, the present invention relates to a skylight having a wide opening frame, for example made with a double wing frame.
- As known, skylights are basically openings made in the roof of a building to illuminate the attic or, more generally, the rooms beneath.
- Given their exposed position, the openings of this type are often protected by specific window frames. Moreover, as skylights are often difficult to reach manually, they are equipped with automated control devices that allow them to be opened or closed remotely.
- The automated devices essentially comprise an actuating motor arranged in the vicinity of the skylight and equipped with at least one gear configured to transmit the motion of the drive shaft to a transmission element, typically a toothed rod, or rack, configured to drive the skylight cover in opening or closing.
- In addition, the roof cover is generally hinged to a portion of the roof on its side opposite to the side on which the gear rod is constrained.
- Devices of this type are, for example, described in patent applications
-
- The known technique described includes some important drawbacks.
- In particular, all skylights equipped with automated control devices may be subject to safety issues, especially in relation to the possibility of ignition of structures, which may also be wooden, arranged in proximity to the motor. Therefore, generally, the skylights of the known technique usually have to be fitted with fire-fighting systems capable of preventing or signalling the risk of ignition.
- In addition, the skylights of the known technique are equipped with control devices that can guide the opening covers at small angles, usually between 10° and 15°, or similar, with the consequence that skylights of the known technique provide a reduced skylight opening and, consequently, a low ventilation capacity for the rooms below.
- In addition, the skylights of the known technique cannot function at high temperatures. In this situation, the technical task underlying the present invention is to devise a skylight capable of substantially obviating at least part of the aforementioned drawbacks.
- In the context of said technical task, it is an important scope of the invention to obtain a skylight capable of reducing, if not completely eliminating, the possibility of fires relating to structures arranged in the vicinity of the control devices.
- Another important scope of the invention is to achieve, therefore, a skylight that does not require special safety equipment, in particular fire safety equipment, for its proper functioning.
- Another task of the invention is to realise a skylight which is also functional at high tem peratures.
- In conclusion, a further task of the invention is to realise a skylight whose cover can be opened widely, so as to provide a greater access opening of the skylight and significantly increase the ventilation capacity of the room beneath.
- The specified technical task and purposes are achieved by a skylight as claimed in the appended
claim 1. - Preferred technical solutions are highlighted in the dependent claims.
- The features and advantages of the invention are hereinafter clarified by the detailed description of preferred embodiments of the invention, with reference to the appended drawings, in which:
- the
Fig. 1 illustrates a side view of a skylight according to the invention in an opening configuration in an embodiment wherein the insulating layer is a coating of the inner walls of the casing; and - the
Fig. 2 illustrates a side view in detail, of the control device of a skylight according to the invention in an embodiment form in which the insulation layer is a casing filler. - In the present document, the measurements, values, shapes and geometric references (such as perpendicularity and parallelism), when associated with words like "about" or other similar terms such as "approximately" or "substantially", are to be considered as except for measurement errors or inaccuracies due to production and/or manufacturing errors, and, above all, except for a slight divergence from the value, measurements, shape, or geometric reference with which it is associated. For instance, these terms, if associated with a value, preferably indicate a divergence of not more than 10% of the value.
- Moreover, when used, terms such as "first", "second", "higher", "lower", "main" and "secondary" do not necessarily identify an order, a priority of relationship or a relative position, but can simply be used to clearly distinguish between their different components.
- Unless otherwise specified, as results in the following discussions, terms such as "treatment", "computing", "determination", "calculation", or similar, refer to the action and/or processes of a computer or similar electronic calculation device that manipulates and/or transforms data represented as physical, such as electronic quantities of registers of a computer system and/or memories in, other data similarly represented as physical quantities within computer systems, registers or other storage, transmission or information displaying devices.
- The measurements and data reported in this text are to be considered, unless otherwise indicated, as performed in the International Standard Atmosphere ICAO (ISO 2533:1975).
- With reference to the Figures, the skylight according to the invention is globally indicated with the
number 1. - The
skylight 1 is suitable to be placed or obtained on a roof of a building. - The building may be of any nature, for example industrial, residential or other.
- The roof may also be of various types, for example flat, or pitched, possibly also curved. The
skylight 1 comprises, in brief, at least one supportingframe 2 and aroof cover 3. - The
frame 2 is preferably integral with a roof of a building. Alternatively, theframe 2 may also be part of the roof. In other words,frame 2 may be an element separate from the roof and solidly firmly constrained to it, or it may be defined by the edges of the hole cut in the roof itself. - In general, the
frame 2 delimits an opening corresponding to the opening of theskylight 1. - In any case,
frame 2 defines asupport plane 2a. - The
support plane 2a is essentially the plane on which theframe 2 expands. Thesupport plane 2a may be perfectly flat or even slightly curved, for example to follow the contour of the roof. - The
frame 2 can take various shapes. For example, it may be rounded or, more appropriately, squared and almost rectangular or square. - The
cover 3 is the portion ofskylight 1 that interacts withframe 2 to make the room below the roof accessible or inaccessible. - The
cover 3 comprises, therefore, at least oneframe 30. - The
frame 30 is preferably counter-shaped to theframe 2. In fact, theframe 30 is suitable for resting on theframe 2 in at least one use configuration. - The
frame 30 also defines acovering plane 3a. - The covering
plane 3a is the plane on which theframe 30 lies. Furthermore, thecovering plane 3a is the plane intended to be aligned with thesupport plane 2a when theframe 30 is lying on theframe 2. - The covering
plane 3a may also be perfectly flat, or slightly curved. If curved, preferably the coveringplane 3a is curved like thesupport plane 2a. - Furthermore, to improve the support between the
frame 30 and theframe 2, theframe 30 may comprise agasket 31. - If present, the
gasket 31 is configured to adhere, in the closed configuration, with theframe 2. In this way, thegasket 31 allows theskylight 1 to be hermetically closed. Thegasket 31, therefore, may extend along all or part of theframe 30 at the contact area between theframe 30 and theframe 2. - The
frame 30 is constrained in a compliant way to theframe 2. In particular, theframe 30 is constrained to theframe 2 by means of constraint means 4. - The constraint means 4 preferably define a
rotation axis 4a. Therotation axis 4a lies on thesupport plane 2a. In addition, therotation axis 4a is the axis around which theframe 30 is rotatable with respect to thesupport plane 2a. Therefore, therotation axis 4a is defined by the line of intersection between thesupport plane 2a and thecovering plane 3a at least when theframe 30 is not resting on thesupport plane 2a. - In particular, the
frame 30 is rotatable to be closed or folded open with respect to theframe 2. The closing is obtained, of course, when theframe 30 rests on theframe 2, the opening is obtained by moving theframe 30 away from theframe 2. - In this way, at least one closing configuration and one opening configuration are defined, respectively.
- When in an opening configuration, of course, the covering
plane 3a defines its own inclination with respect to thesupport plane 2a. - Thus, the covering
plane 3a can define an inclination angle α. - The inclination angle α is essentially the angle defining the opening of
cover 3 with respect toframe 2 and thus to the roof. - From a structural point of view, the constraint means 4 may include a mechanical hinge extending along part of the
frame 2 and theframe 30. - For example, if
frame 2 andframe 30 define rectangular shapes, the hinge may be positioned along a corresponding long side or even a corresponding short side. - In addition, the
gasket 31 preferably extends along the part of theframe 30 that is not connected to theframe 2 via the constraint means 4. - The
skylight 1 further comprises acontrol rod 5. - The
control rod 5 is an elongated, substantially beam-like element in which one dimension preponderates over the other two. - The
control rod 5 defines, therefore, anexpansion trajectory 5a. Theexpansion trajectory 5a is the trajectory along which the preponderant dimension is developed. Furthermore, theexpansion trajectory 5a may be straight or curvilinear. - Preferably, the
expansion trajectory 5a is curvilinear. In detail, overall, thecontrol rod 5 defines an arc of a circle having a corresponding centre at a point of therotation axis 4a. - The
control rod 5 may further be a simple rod or bar movable by rollers. Or, preferably, thecontrol rod 5 may be a rack. As is well known, a rack is an element provided with holes or teeth configured to interact with a crown wheel or gear to be moved. - In any case, the
control rod 5 is connected to thecover 3, in particular to theframe 30, in an area distanced from the constraint means 4. Preferably, thecontrol rod 5 is constrained to thecover 3, preferably to theframe 30, such that theexpansion trajectory 5a is transverse to the coveringplane 3a. - The
control rod 5 could be connected to a free end of theframe 30 opposite to the end connected to theframe 2 via the constraint means 4. - Furthermore, the
control rod 5, at the same time, could be connected in a compliant way to theframe 30, for example via a hinge defining an rotation axis parallel to therotation axis 4a. - The
skylight 1 additionally comprises acontrol device 6. - The
control device 6 is preferably integral with thehinge 2. Thus, thecontrol device 6 does not move together with theframe 30 and the latter moves with respect to thesame control device 6. More in detail, thecontrol device 6 is configured to move theframe 30 itself. - In particular, the
control device 6 comprises a motor 60. - The motor 60 is operatively connected to the
control rod 5. Therefore, the motor 60 may include both power means and movement means, for example gears, capable of interacting with thecontrol rod 5 to move it. Indeed, in general, the motor 60 is configured to move thecontrol rod 5 along theexpansion trajectory 5a relative to theframe 2. In this way, thecontrol rod 5 pushes or pulls theframe 30 away from or towards theframe 2 to realise the opening and closing configurations. - The features just described are common to most automated skylights of the known technology.
- However, advantageously, the
skylight 1 also includes acasing 7. - The
casing 7 is essentially a closed, or partially closed, element configured to contain one or more components of theskylight 1. - Preferably, the
enclosure 7 definesinner walls 70. - The
inner walls 70 are intended to enclose the components. In particular, theinner walls 70 extend at least around the motor 60. Thus, theenclosure 7 comprises at least the motor 60. The latter may be permanently bound to one or moreinner walls 70 or be supported on one or moreinner walls 70. - Advantageously, the
enclosure 7 also comprises at least oneinsulation layer 71. - The
insulation layer 71 is positioned on theinner walls 70. Thus, it is substantially at least one cladding of theinterior walls 70. - Furthermore, the
insulation layer 71 includes thermal insulation material surrounding the motor 60. - Advantageously, the thermal insulating material may comprise rock wool or similar (ceramic fibre, calcium silicate, etc.).
- Advantageously, in addition, the
control device 6 may comprise areducer 61. Thereducer 61 is operatively connected between the motor 60 and thecontrol rod 5. - The
reducer 61 is, therefore, configured to transmit a power developed by the motor 60 to thecontrol rod 5 with a predetermined reduction ratio. - As a whole, therefore, the motor 60 and the
reducer 61 define a geared motor. - In particular, considering that the
cover 3 defines an own weight and an angular momentum, determined by the weight, with respect to therotation axis 4a tending to bring thecover 3 in a closed configuration, thereducer 61 is preferably configured in such a way that the predetermined reduction ratio determines a resultant torque sufficient to overcome the angular momentum to define a maximum inclination angle α at least equal to 45° or even higher. - Furthermore, since the
reducer 61 is the component capable of transmitting the motion to thecontrol rod 5, preferably it is operatively connected to thecontrol rod 5 by means of a gear. Thecontrol rod 5, which comprises a rack in the preferred embodiment, can be moved by the rotation of the gear determined by the predetermined reduction ratio with respect to the rotation of the motor shaft 60. - If the
control device 6 is provided with areducer 61, thecasing 7 may also comprise thereducer 61. Thus, thecasing 7 also includes part of thecontrol rod 5. In this case, thecasing 7 also includes holes or openings through which thecontrol rod 5 can be moved relative to thecasing 7 via thereducer 61. - In this embodiment, therefore, the
insulation layer 71 entirely surrounds both thecontrol device 6 in its entirety and part of thecontrol rod 5. - Additionally, in any configuration, i.e. both in the configuration in which the enclosure includes only the motor 60, and if the enclosure includes the
entire control device 6 and part of thecontrol rod 5, the insulatinglayer 71 may be a filler. Therefore, it can be configured to completely fill the empty interior spaces of thecasing 7, as shown inFig. 2 . - In conclusion, the
skylight 1 may comprise a further arrangement. - For example, it may include safety means 8. The safety means 8 are components intended to protect the environment below the
skylight 1 from falling objects from theskylight 1. Therefore, they are preferably arranged near or on theframe 2 and are slender so as not to burden the overall structure. - Preferably, the safety means 8 include an anti-fall net. The net is integral with the
frame 2. Furthermore, it is positioned on a side of theframe 2 opposite to thecover 3. In other words, the safety means 8 are preferably positioned between the opening of theskylight 1 and the ground. - The operation of the
skylight 1 described above in structural terms is substantially similar to the operation of any automated skylight. - The
control device 6 essentially moves thecontrol rod 5 along theexpansion trajectory 5a in such a way as to push thecover 3 in opening or closing on theframe 2. - The
skylight 1 according to the invention achieves important advantages. - In fact, the
skylight 1 makes it possible to reduce, if not completely eliminate, the possibility of fires relating to the structures arranged in the vicinity of the control device since the latter is well insulated, by means of the insulatinglayer 71, within theenclosure 7. - In other words, the structure of
skylight 1 is substantially fireproof and enables it to meet the B300 heat resistance tests as provided for in standard 12101/2. - Furthermore,
skylight 1 does not require any special safety equipment, in particular fire protection, for its proper functioning and can cooperate and be controlled by it. - In conclusion, the
skylight 1 comprises acontrol device 6 which allows thecover 3 to be opened widely, so as to provide a greater access opening of the skylight and significantly increase the ventilation capacity of the room beneath. - The invention is susceptible to variations within the scope of the inventive concept as defined by the claims.
- Within this scope, all details are substitutable by equivalent elements and the materials, shapes and dimensions can be any.
