Description of the Industrial Invention entitled: << PACKAGING SHUTTER EQUIPPED WITH STAVES WITH INNOVATIVE HOOKING SYSTEM TO CLOSE LIGHTS OF CIVIL AND INDUSTRIAL BUILDINGS SAFELY "

The present invention relates to a folding shutter equipped with slats with an innovative reciprocal hook coupling system, to safely close access openings and lights of civil and industrial buildings.

The present invention is, in particular, an improvement of the patent application for invention no. BA2010A000030 of 26.07.2010 by the inventor himself, as he solves the problems related to the danger of shearing and pinching presented by said invention and due to the fact that before each plank or modular panel constituting the old covering was released from the others in the closing phase, while now, with the present improvement, the conformation of the ends of the lateral supporting connecting rods of each panel or stave has been modified, providing said ends with a particular hook-like conformation, capable of catching and constraining the door leaves in a burglar-resistant manner .

With said innovative hook shape designed to mutually connect the same modular panels or slats during the closing phase of the packing shutter, therefore, said shearing and pinching problems of the known art have thus been definitively resolved.

The present invention is also new and inventive in that it solves another important problem related to the use of high thicknesses for making panels or slats for shutters in the case of anti-burglary security applications. In fact, in the known technique, solid modular metal slats and / or with high thicknesses are not produced, based on these for three reasons:

- processing difficulties in the bending treatments of thicknesses already greater than 12 tenths of a millimeter;

- high costs of steel sheets with thicknesses greater than 16 tenths of a millimeter

- further undesirable costs due to greater difficulties in working the metal sheets of high thickness, in particular in the realization of curl bending conformations for the reciprocal waxing of the ends of the metal slats;

- high overall weight of the shutter curtain, generating problems related to resistance and, therefore, to the choice {also as a function of the relative higher cost} of the gearmotors necessary for the automation of the shutter opening and closing phases,

The present invention has therefore been devised to solve the disadvantages of the presently known closing systems and fundamentally; correlated to - criticalities in the use of free metal slats in retieffraction installations, with evident danger of pinching and shearing; - criticality in the adoption of low thicknesses of the sheets for the realization of current modular slats not adequate in guaranteeing security for anti-burglary installations;

criticality in the hinging methods of the modular slats themselves, currently unsuitable to resist burglary;

criticality in the sliding modality of the modular slats inside the lateral guides, especially for anti applications. The present invention also solves further problems connected with the packaging of the modular staves in the box, especially when opening the shutter, which up to now have caused the following further disadvantages;

high complexity of the component elements of the current closing systems, often also using reciprocal wax rods; high friction present between the hinging elements of the slats, as well as in the sliding on the guides, with high noise of the current anti-burglary safety closing system;

difficulties, in the phases of industrial realization of staves with high thicknesses, both for the realization of the same staves, and for the relative assembly and installation of the mantle;

impossibility of reducing the volumes occupied by the mantle when opening it;

limited durability and reliability of the closing system over time, with high maintenance costs for the final part;

very limited or no versatility to modify the type of staves making up the mantle.

The main object of the present invention is therefore to completely overcome all said limitations and disadvantages of the known art.

A further object of the present invention is to provide a folding shutter which performs at the same time the function of being also a valid anti-burglary grate and solves, as an improvement, said problems presented by patent no. BA2010A000030 of 23.07.2010 by the same inventor.

Another object of the present invention is to provide a folding shutter which is equipped with

- modular staves rigidly hinged together from the moment the shutter starts the closing phase;

- modular slats free when completely open, with the same slats packed in the box and easily removable from it in the case of periodic or extraordinary maintenance,

These purposes are achieved by making a folding shutter 1 for access openings and lights of civil and industrial buildings, characterized in that it is basically constituted by: a pair of vertical guides 6, ending in an inclined way 9 inside a box 8 , in which a means 11 for lifting the door 5 of the shutter 1 is enclosed; said curtain 5 of the shutter 1 in turn constituted by a plurality of modular panels or staves 2, with each stave 2 formed by a pair of connecting rods 3 sliding in the lateral guides 6 and connected to each other by metal profiles or bars 4 forming the frame base of the staves 2, with the latter not mutually constrained to each other when packed in the box 8, but automatically hook together by reciprocal hinging when closing the shutter 1, the connecting rods 3 being equipped at their ends 13-14 with coupling means having a particular hook shape 17, thus providing an effective and efficient anti-burglary mode of the same slats 2, right from the initial closing phase of the shutter 1.

One of the immediate advantages of the present closing system 1 is basically that of allowing the curtain 5 to be packed in a very small space in the box 8, with the further advantage of having, at the same time, inside the same box 8, panels or slats 2, no longer bound together and, therefore, easily removable.

These and other advantages and characteristics of the closure system 1 according to the present invention will become more clearly evident from the following detailed description of a preferred reacting form thereof, given by way of non-limiting example, made with reference to the attached drawings in which.

- Fig.1 is a sectional side view of said closing system 1 showing the slats 2 constituting the door 5 and the upper and lower portion of the shutter 1. in order to highlight its salient parts, that is to say a box 8, inside which is enclosed a motor reducer 12 suitable for lifting the curtain 5 by means of ropes 11, sliding along the vertical guides 6 and inclined 9, on bearings rolling mechanism 7, hoisted in the opening phase by means of the beach or the last lower slat 10 of the mantle 5 of the shutter 1; Fig.2 is a lateral axonometric view of a stave 2 in the configuration of an anti-burglary grating or base grating, on which panels in thick solid sheet metal or other various types are rigidly and irremovably applicable; in the same figure the fundamental parts constituting the stave 2 are also evident, that is to say a pair of connecting rods 3, equipped in the lower 13 and upper 14 ends with bearings 7 to facilitate the sliding of the stave 2 along the vertical guides 6 and inclined 9 of the damper 1, as well as the metal profiles or connecting bars 4 of said connecting rods 3 '

Fig, 3 is a perspective plan view of said stave 2 of the previous Fig. 2, in which now the connecting rod 3 is seen from above and only the bearings 7 of the upper end of the same connecting rod 3 and the upper metal profile 4 of stave 2;

Fig. 4 is a slightly enlarged sectional side view of Section A-A of the connecting rod 3 of Fig. 2, from which the hook shape 17 of the ends for mutual attachment to the other connecting rods 3 supporting other panels or slats 2 can be better seen the position of the bearings 7 in the upper 14 and lower 13 ends of the connecting rod 3 is also clearer from the same figure;

Fig. 5 is a side view, from the external and not internal side as previously represented in Fig. 4 in Section A-A, of a pair of connecting rods 3, from which the reciprocal coupling methods through said hook ends 17 of the the same connecting rods 3 supporting the slats 2;

Fig. 7 is a front elevation view of a portion of the mantle 5 consisting of the coupling of two slats in the configuration with high-thickness non-insulated metal paneling 16, where in the left-hand portion it has been shown together with a vertical guide portion 6, while the right-hand portion has been shown without vertical guide 6 to better illustrate the connection modalities of said hooked ends 17, now also present in correspondence with the profiles of the sheets forming said panels 16 as well as in the coupling of the connecting rods 3;

- the. 6 schematically shows in side view the representation of Sect. B-B represented in Fig. 7 of said portion of the covering 5 inside the vellical guide 6:

- Fig. 9 shows an enlargement of detail A highlighted in Fig.8.

where the methods of hooking the hooked ends 17 of the connecting rods 3 inside the lateral guide 6 are better understood;

- Fig, 11 shows a three-dimensional schematic view of a single anti-friction plate 16, provided with hooked curved ends 17 like the curved ends of the connecting rods 3,

With reference to the eleven figures previously described and attached hereafter, it is immediately evident, even to a technician not expert in the field of closing systems, that the present invention, in the particular preferred solution reported therein, is basically constituted by a covering formed by a plurality of modular slats or panels 2, sliding on bearings or other similar members 7 inside a pair of vertical guides 6 in order to minimize the frictions present therein, with said slats 2 folding, under the thrust of a beach lifter 10, pulled upwards during opening by a motor reducer 12, along a pair of vertical guides 6 and subsequently inclined 9, forking inside the box 8. From the same figures it is also evident that the slats 2 are subsequently "packed" inside the same box 8 in a minimized volume due to the particular type of packaging adopted with said connecting rods 3.

The peculiarity of the present invention, with respect to the known art represented by said patent no. BA2010A000030 of 28.07.2010 by the same inventor is inherent in the way of making said connecting rods 3, which as can be seen better in figures 4. 5, 6, 7, 8, 9, 10 and 11, are made in such a way as to present at its lower ends 13 and upper 14 an innovative hook shape 17,

Said particular hook configuration 17 of the connecting rods allows a firm reciprocal coupling of the same connecting rods 3 supporting the slats 2 both in the grating solution, i.e. with simple connection profiles 4 consisting of bars 4 {as can be seen from figures 2, 3 and 6), and in the shutter configuration with anti-burglary curtain 5 (as can be seen from figures 7, 10 and 11).

The movement of the entire manie 5 is carried out by pulling the last element or lower slat of the chin 5, usually a beach delto, which will behave like a beach lifter 10, activated in its upward pulling movement by a gearmotor 12, by means of lifting means 11 such as ropes or chains, as shown in Fig.1.

The conformation of the pair of vertical guides 6 is such as to present, in proximity to the box 3, a bifurcation in a pair of inclined guides 9, to allow an optimal occupancy of a minimized volume during the packing phase of the mantle 5, as best possible evineo always in Fig.1.

The shutter 1 has the further peculiarity of being able to couple to said modular metal profiles 4 any possible existing paneling means 13, i.e. transparent or opaque glass panels, insulated panels, anti-burglary gratings, shutters or venetian blinds, and even photovoltaic panels if the exposure of the lights to be closed is favorably exposed to the South.

However, the folding shutter 1 according to the present invention is fundamentally characterized by the particular configuration of the lateral connecting rods 3 for sliding in the guides 6, 9, which optimize in an incomparable way the functional characteristics relating to:

- easy lifting during the opening phase of the curtain 5;

- the rapid of the mantle 5 inside the box 8 when fully opened, with the possibility of replacing and maintaining the individual panels through the possibility of access, by opening the closing means 10 of the box 8 itself;

- the rapid and safe descent of the curtain during the closing phase, without the danger of shearing and pinching.

the lifting of the closing system 1 takes place by means of a vertical traction of the terminal element of the mantle 5 or lifter 10, The traction of the beach 10 occurs by means of lifting means 11, such as ropes or chains, pulled by a gear motor 12, easily accommodated in the same box 3. The upward movement of the mantle, made up of all the other panels 3 bound to the frames 2, takes place through a push from below received by the beach 10.

A plurality of ball bearings 7 minimize the friction present during sliding in the lateral guides Q and inclined guides 9, also reducing the noise of the shutter 1.

The thrust that each connecting rod 3 receives, having the cross-sectional shape of a parallelogram, to slide upwards along the guides 6 up to the inside of the box 3 along said inclined guides 9, is guaranteed by the particular conformation of the contact and reciprocal thrust sides of the same connecting rods 3.

Said thrust generates a lateral displacement of the same connecting rod 3 in order to allow the packing of the individual slats 2 along said inclined guides 9 contained inside the box 8, minimizing the volume occupied by them.

When the curtain 5 is fully opened, it is packed by inserting a bifurcation at the top end of each side guide 5, splitting into a double inclined guide 9.

Finally, the closure takes place by causing the beach 10 to descend by gravity under the braked action of the gearmotor which, resuming its vertical stroke downwards in the lateral guide 6, frees the space for descent by the thrust of the mere gravitational component of the constituent slats 2 the mantle 5,

The present closing system has a very simple assembly with further advantages in terms of transport, handling and installation costs

The mantle can be made in such a varied way also with hybrid paneling means 3, so that it is possible to protect lights of any development both in width and in height.

The advantages deriving from the use of the present invention are innumerable and indisputable and basically derive from having conceived a packing shutter for civil and industrial lights equipped with simplified mechanics both from the construction point of view and in the baskets of starting materials, with further advantages represented by the possibility of being able to satisfy any need of consumers in terms of aesthetics due to the fact of being equipped with paneling means that can be modified at will, as well as being further ergonomic to be modified also for the maintenance technician. It is also evident that numerous retouching, adaptations, additions, variants and replacements of elements with other functionally equivalent ones may be made to the embodiment previously described for illustrative and non-limiting purposes, without however departing from the scope of protection of the following claims.
