The subject of this invention is a device designed to adjust the inclination of panels to be installed on a building element so as to define technical structures for protection and/or boundaries and/or furnishing, for example, parapets, railings, banisters, fences, partitions, glazed windows, cantilever roofs, roofs or the like.
More precisely, the purpose of this device is to provide a system that connects panels of any thickness and material (e.g., glass), comprising the means to quickly adjust their inclination with respect to a building element of installation. The device is therefore suitable for use in the field of construction, particularly in the field of transparent architecture.
Of course, nothing prevents the application of the finding to be extended also to fields different from the building one, such as the nautical field.
It is well known that, for the installation of panels on supportive building structures and/or surfaces to be delimited or that need protection, metal profiles are often used, preferably aluminium, which can be anchored to the building component and adapted to serve as a seat and support for said panels, retaining them in a horizontal or vertical position according to the different applications. See, for example, the solutions described and illustrated in documents WO 2016/193806 A1 and/or WO 2018/015800 A1.
Many well-known systems, despite being widespread and already having been in use for a long time, are not free from difficulties in the positioning and installation of the panels
If we can certainly admit that all the elements making up an apparatus for connecting panels are perfect from the dimensional point of view or better that their imperfections are absolutely imperceptible and irrelevant from a functional point of view, the same can not be said of the building components whereon such devices must be constrained that may have defects and unacceptable dimensional inaccuracies.
Very often, therefore, to compensate for defects of the lying plane of the installation surface of said profiles, ensuring, as a result, the optimal set-up of the panels that they support, fitting works, adjustments and the masking of said dimensional defects are required. This inevitably ends up complicating and lengthening installation times, as well as requiring close attention and technical preparation on the part of the installers.
It is not always easy to place panels in the correct and desired position, especially if the installer has to work in rather uncomfortable or dangerous places and positions: very often, in order to carry out the assembly of the panels and any adjustment of the set-up thereof, the installer must operate from the outside of the building component of installation, leaning in the mid-air or using special equipment, such as aerial platforms or ladders, at the risk of his own safety.
An incorrect positioning of the panels on the support profile leads to installations that are aesthetically unsatisfactory and/or not fully functional.
Set-up defects are in fact very visible on an array of consecutive panels, especially if having a glossy and/or reflecting surface.
In addition, the current systems used to adjust the set-up have numerous components and require the construction of profiles with a complex shape. This does not facilitate the production and the installation of said systems.
The object of the present invention is to eliminate the drawbacks of the prior art listed above, by designing an innovative apparatus for connecting panels, preferably glazed, to a building component and defining technical structures for the protection and/or delimitation and/or furnishing, such as, by way of a non-limiting example, parapets, railings, balustrades, fences, partition walls, cantilever roofs, roofs and similar elements.
More specifically, the aim of this invention is to provide an innovative system to adjust the set-up of one or more panels to compensate for any dimensional and/or of the planarity defects the installation surface.
A further aim of the invention, at least for one or more embodiments, is to provide a system for adjusting the set-up of one or more panels of any thickness installable by an installer operating in totally safe conditions.
A further aim of this invention, at least for one or more embodiments, is to provide an adjustment system which is easy to realise and comprising a reduced number of components.
These and other aims are achieved according to the invention, with the features listed in the annexed independent claim 1.
Further features of the present invention shall be better highlighted by the following description of a preferred embodiment, in accordance with the patent claims and illustrated, purely by way of a non-limiting example, in the annexed drawing tables, in which:
a, b, c, d, e show different stages of a possible method for adjusting the laying set-up of a panel;
The elements of the apparatus according to the invention are now described using the references contained in the annexed figures. It should be noted that any dimensional and spatial term (such as “lower”, “upper”, “right”, “left”, “vertical”, “horizontal” and the like) refers, unless otherwise indicated, to the position according to which the object of the invention is shown in the drawings which not necessarily coincides with the position of the finding in operating conditions. With the purpose of highlighting some features instead of others, not necessarily what described in the annexed drawings is perfectly to scale.
For the sake of simplicity and without any restrictive intent, the term, “panel” is henceforth to be understood as any substantially slab-shaped structural element capable of creating and establishing a technical structure for protection and/or boundaries and/or furnishing, such as: parapets, railings, banisters, fences, partitions, glazed windows, cantilever roofs, roofs or the like.
In general, said panel may include metal sheets, polycarbonate sheets, glass panels, wood, etc., of various thicknesses and finishes.
As clearly shown in the accompanying figures, shown by way of example and by no means an exhaustive list,
Said connecting apparatus 1 comprises a support profile 2, capable of supporting and retaining at least part of a panel 3.
Said support profile 2 can be made of any suitable metal alloy (aluminium alloys, in general) but there is nothing to prevent it being made from other materials, e.g. wood or PVC, if structural requirements allow for this.
The support profile 2 may have a substantially U-shaped section with an anchor base 20 fixed, through known means 6, to an installation surface of said building element, and a first 21 and second 22 wing, opposite and parallel to each other. Between said wings 21, 22 and the base 20, a cavity 23 is defined acting as a seat for at least a portion or edge 30 of the panel 3, which projects outwards for its remaining part.
In general, said edge 30 cooperates with a suitable support surface inside of said cavity 23.
Preferably, said edge 30 is supported by at least one rib 24 made on each of the two wings 21 and 22 of the support profile 2, projecting inwards from the cavity 23 and advantageously positioned close to the base 20 of said profile, parallel to it.
As will be seen, between said edge 30 and said rib 24 there may be a specific means of support, for example a tab or plate 411, which will be described in greater depth over the course of the discussion with reference to the other functions which it is capable of performing.
Of course, nothing prevents that said edge 30 of the panel 3 could be supported directly by the base 20 of the profile 2.
The connecting apparatus 1 according to this invention further comprises a system to adjust the laying set-up of the panel 3 with respect to the support profile 2, which makes it possible to:
For this purpose, said laying set-up adjustment system comprises an adjustment assembly 4 suitably designed to:
More specifically, said adjusting can be achieved by rotating the edge 30 of the panel 3 around said fulcrum F and within the cavity 23 of the support profile 2, between its first 21 and second 22 wings.
According to a preferred form of the invention, said adjustment assembly 4 may preferably comprise:
According to the invention, a temporary coupling is provided between the adjuster support 40 and the stop plate 41 in order to join the parts and facilitate the insertion and installation of the adjustment assembly 4 inside the cavity 23 of the profile 2.
This coupling, in accordance with a possible manufacturing variant, can however be released or altered so as to disconnect the parts and allow, as will be seen, the free movement/translation of the adjuster support 40 inside the profile 2 and the consequent adjustment of the inclination of the panel 3.
As illustrated in
For this purpose, the stop plate 41 may be provided with at least one tab or plate 411:
Said interlocking pin 42 may have a weakened section so as to facilitate its breaking during the adjustment procedure. We will return to this aspect in greater detail in the course of this discussion.
In accordance with a preferred embodiment of the invention, said adjuster support 40 should preferably be made of an elastically deformable material.
In this way, as will be seen, by operating the aforementioned actuators 400, said support 40 is suitably deformed so as to allow a crosswise translation of at least a portion thereof inside the cavity 23 of said profile 2 and a consequent interaction of the same with the opposite face of the panel 3, thereby allowing a rotation of at least its edge 30.
Preferably, said at least two actuators 400 include:
Furthermore, as shown in
In other words, the distal actuator 402 must not be an obstacle that prevents the manoeuvring tool 8 from interacting with the proximal actuator 401.
As clearly shown in
According to said arrangement, when the second head 142 rotates on the threaded pin 141, which is fixed and locked to the adjuster support 40 via the first head 140, there is a corresponding crosswise translation, inside the cavity 23 of the profile 2, of the part of the adjuster support 40 to which it is constrained, said translation, as already partly described, causing a consequent rotation around the fulcrum F of at least the edge 30 of the panel 3.
In fact, said second head 142 is substantially in contact with the internal wall of the first wing 21 and when it is activated using the tool 8, it transfers the rotation movement to the first head 140 via the threaded pin 141.
Said first head 140, which is placed and locked inside the blind seat 406, unable to rotate or translate, “releases” the movement generated by the second head 142 on the adjuster support 40, elastically deforming at least the area surrounding said seat 406.
Therefore, the adjuster support 40 transfers the movement of the actuators 401 and 402 to the edge 30 of the panel 3, via a controlled deformation of its parts surrounding the blind seats 406 on which the respective heads 140 are positioned.
Said movement of the actuators 401 and 402, in combination with the abutment surface 410, allows the panel 3 to rotate around the fulcrum F and therefore to adjust its inclination with respect to the building element.
For this reason, the aforementioned abutment surface 410 of the stop plate 41 is fixed and preferably convex so that each of its points can act as a fulcrum F during the rotation of the edge 30 of the panel 3.
To ensure that said rotation occurs, the projection of the fulcrum F on the opposed first wing 11 should preferably “fall” in the space H between the proximal actuator 401 and the distal actuator 402.
There is, of course, nothing to prevent the abutment surface 410 from being substantially flat but equipped with at least one suitable abutment element (not shown in the figures) from which it protrudes to act as a fulcrum F.
Therefore, as shown in the attached figures, by screwing/unscrewing each of the actuators 401 and 402 with the aid of a tool 8, the adjuster support 40 can be translated, by deformation of the latter, transversely within the cavity 23 of the profile 2 to the most suitable extent for adjustment.
More precisely, by suitably acting on the actuators 401 and 402, it is possible to translate the part of the adjuster support 40 surrounding the distal actuator 402 against the panel 3 and, at the same time, it is possible to retract the part of the support 40 surrounding the proximal actuator 401 in the opposite direction, thereby causing a clockwise rotation of the panel 3; vice versa, the panel 3 can rotate counter-clockwise if actuators 401 and 402 are operated in the opposite manner.
In essence, the adjuster support 40 is deformed by changing the reciprocal position of at least the portions comprising the blind seats 406 in which the respective actuators 401, 402 are located.
Such translations will naturally be prolonged until the desired inclination of the panel 3 is reached.
The results of the rotation of the panel 3 in the respective support profile 2 are clearly visible in
In accordance with a possible manufacturing variant of this invention, the adjuster support 40 may comprise a plurality of proximal 401 and/or distal 402 actuators so as to adapt the adjustment assembly 4 to different types of loads and to effectively improve the distribution of the stresses along the edge 30 of the panel 3.
For example, in the case of a banister, if it is possible to predict in advance the type and direction of the load the banister must respond to, the adjuster support may provide:
In accordance with a possible manufacturing variant of the invention, this can be advantageously achieved by making a T-shaped adjuster support 40 comprising a plurality of said blind seats 406 (e.g., blind holes), suitably and variably shaped to accommodate the actuators 401, 402.
In this case, by inverting the “T”, i.e. by changing the orientation of the adjuster support 40 inside the profile 2 where it is mounted, it is possible to counteract and respond adequately to the different types of load that are expected to act on the panel 3 when in use and operational (
In addition, the adjuster support 40 can be fitted with a lightening central cavity or opening 405 and adapted to make it more deformable during the aforementioned adjustment phase.
A possible adjustment procedure for the inclination of the panel 3, illustrated in
In general, depending on the actuator operated and the translation exerted, the interlocking pin 42 can be broken:
As already mentioned several times, the apparatus for the connection of one or more panels 3 to a building element according to this invention can be used to make parapets, railings, banisters, fences, partitions, glazed windows or similar frames, as illustrated in
In these figures, the deformation of the adjuster support 40 is clearly visible and it is also clearly understandable how this deformation is dependent on and varies according to the adjustment made.
In order to facilitate the aforementioned operations of adjusting the inclination and locking the panel 3, the wing 21 upon which the adjuster support 40 is placed should preferably be the one which can be reached by the installer without the need to lean out dangerously or to use aerial or suspension equipment.
In this way, the installer can always install and adjust the set-up of the panel 3 in a completely safe and comfortable manner.
For example, in the case of fitting banisters, parapets or the like, said first wing 21 is the one facing the inside of the building element of installation, while the opposite wing 22 which holds the stop plate 41 is the external one.
Similarly, in the case of cantilever roofs and roofs, the first wing 21 is the one normally directed towards the ground or a walkway accessible to users, while the second wing 22 is the one directed upwards, e.g. towards the sky.
It is clear that, in the practical implementation of the invention, numerous modifications and further variants may be possible, all falling within the same inventive concept; moreover, all the various components and details described above may be replaced by technically equivalent elements.
For example, there is nothing to prevent the adjuster support 40 from being equipped with one or more spacers 9 that allow the adjustment assembly 4 to cooperate with panels 3 of different thicknesses.
Said spacers 9 may be positioned on the side of the adjuster support 40 in direct contact with the edge 30 of the panel 3 and, depending on the type of application, may have different thicknesses.
Each distance S can therefore be suitably adapted to accommodate panels 3 of different thicknesses, making the support profile 2 adaptable to many applications and types of panels 3.
Furthermore, according to a possible manufacturing variant, there is nothing to prevent the above-mentioned stop plate 41 from being integrated to and part of the wing 22 of the profile 2.
Although, in
In fact, it has been found that having a hollow structure in the support profile 2, in particular in its wings 21, 22, substantially reduces the weight of the connection apparatus 1 and the risk of breaking the panel 3, especially if it is made of glass, both during the adjustment of its inclination, as illustrated, and, under operating conditions, when subjected to heavy loads, such as accidental impacts, strong wind, or other occasional atmospheric disturbances.
More precisely, the presence of one or more of said cavities 26 makes the wings 21, 22 more elastic and/or flexible, thus offering less resistance when adjusting the inclination of the panel 3 or in the presence of said accidental and/or occasional loads, and reducing, as a consequence, the risk of its breakage.
Without any restrictive intent, said cavities 26 may be formed according to a predetermined arrangement, for example such as to form a substantially reticular and/or honeycomb structure, or, alternatively, they may be located only in certain points of said wings 21, 22, for example in areas which are most likely to offer resistance to the adjustment of the panel 3 or to said loads.
It has also been found to be particularly useful to use one or more of said cavities 26 to house at least one light source 5, for example an LED light, with the purpose of illuminating the panel 3.
For example, said light source 5 can be inserted into a cavity 26 of said wings 21, 22 preferably located close to the base 20 of said support profile 2, so as to allow illumination from below of said panel 3. From an inventive point of view, however, alternative locations for said light source 5 are completely indifferent and technically equivalent; for example, the light source 5 can be located inside the seat 23 of the support profile 2, which is normally suitable for retaining and accommodating a portion or edge 30 of the panel 3, and substantially supported by the base 20 of said profile 2, and/or in a specific housing located on said base 20.
Finally, it should be pointed out that, like the “solid” support profiles 2, the “hollow” ones in
By way of example, the support profiles 2 of
With specific reference to the variant of the support profile 2 shown in
For example, said attachment 20.a can allow greater freedom of installation, depending on the dimensional and surface characteristics of the building element and, at the same time, provides an additional surface for the fastening system 6 of the supporting profile 2 on the building element itself. This allows access to said fastening system 6, for example for maintenance and/or adjustments, without first having to remove the panel 3 from the relevant profile 2 (as is the case with the variants in
Furthermore, it is possible to provide said support profiles 2, both “hollow” and “solid”, with specific covers or casings 7 applicable, e.g, in a “Snap-on”, or interlocking manner or similar, for aesthetic purposes or for protection of the profiles 2 of the invention or parts thereof.
Finally, there is nothing to prevent appropriate and well-known gaskets 70 being provided for the cavity 23 of the support profile 2 adapted to retain the portion or edge 30 of the panel 3, said gaskets may cooperate with the covers 7 themselves and/or with the distal ends of the wings 21 and/or 22 of the profile 2 itself.
In conclusion, the apparatus for connecting one or more panels 3 to a building element according to this invention facilitates:
