Description

“Grata di sicurezza a scomparsa” "Retractable safety grille"

La presente invenzione si inquadra nel settore dei serramenti di sicurezza e, più in particolare in quello delle grate installate allo scopo di impedire l’accesso non autorizzato all’interno di abitazioni o edifici in genere, attraverso le porte o le finestre. The present invention is part of the security door and window sector and, more specifically, that of the grates installed in order to prevent unauthorized access inside homes or buildings in general, through doors or windows.

Come è noto, per proteggere le abitazioni o gli esercizi commerciali da accessi non autorizzati si utilizzano grate o inferriate metalliche. Sono queste normalmente di diversi tipi, quelle più semplici sono fisse e si utilizzano per la protezione di aperture che non prevedono il passaggio di persone. As is known, metal gratings or grates are used to protect homes or businesses from unauthorized access. These are normally of different types, the simpler ones are fixed and are used for the protection of openings that do not provide for the passage of people.

Mentre per la protezione di aperture che prevedono il passaggio di persone o cose, si utilizzano modelli ad una o più ante, ovvero del tipo scorrevole. While for the protection of openings that provide for the passage of people or things, models with one or more doors, or the sliding type, are used.

Sono altresì note grate che prevedono che tutti gli elementi costituenti la grata possano essere impacchettati all’interno del cassonetto, che normalmente è utilizzato per il riavvolgimento degli avvolgibili. Grids are also known which provide that all the elements making up the grate can be packed inside the box, which is normally used for rewinding the roller shutters.

Più in particolare dette grate sono caratterizzate dal fatto che le barre trasversali presentano all’estremità una coppia di rulli che si impegnano nelle guide laterali, quest’ultime in prossimità della loro estremità superiore si incurvano sdoppiandosi in due tratti paralleli la cui distanza corrisponde alla dimensione longitudinale delle barre trasversali, ne consegue che in posizione di chiusura le barre trasversali medesime si impacchettano sui tratti terminali delle guide. Le grate a scomparsa note di quest’ultimo tipo presentano una serie di inconvenienti fra i quali la complessità della meccanica, l’essere soggette ad inceppamenti e la difficoltosa manutenzione. More specifically, said gratings are characterized by the fact that the transversal bars have at the end a pair of rollers which engage in the lateral guides, the latter bending in proximity to their upper end splitting into two parallel sections whose distance corresponds to the size longitudinal section of the transversal bars, it follows that in the closed position the transversal bars themselves pack on the end sections of the guides. The known retractable gratings of the latter type have a number of drawbacks including the complexity of the mechanics, being subject to jams and difficult maintenance.

Scopo della presente invenzione è quello di fornire una grata di sicurezza del tipo a scomparsa dotato di una meccanica di tipo semplice e, pertanto, più economica rispetto a quelle utilizzate nelle grate dello stesso tipo note. The object of the present invention is to provide a safety grate of the retractable type equipped with a mechanics of the simple type and, therefore, cheaper than those used in known grates of the same type.

Un ulteriore scopo è quello di fornire una grata a scomparsa di facile realizzazione e che non sia non soggetta ad inceppamenti. A further object is to provide a retractable grate that is easy to manufacture and is not subject to jamming.

Un ultimo scopo è quello di fornire un sistema di trascinamento e contemporaneo impacchettamento degli elementi costituenti una grata di sicurezza. A final object is to provide a system for dragging and simultaneously packing the elements constituting a safety grate.

Detti scopi sono raggiunti da una grata di sicurezza a scomparsa la quale presenta il vantaggio di non necessitare di rulli posizionati all’estremità delle barre verticali allo scopo di consentire lo scorrimento delle barre medesime all’interno delle guide. These purposes are achieved by a retractable safety grate which has the advantage of not requiring rollers positioned at the end of the vertical bars in order to allow the sliding of the bars themselves inside the guides.

Un ulteriore vantaggio consiste nel fatto che le guide di scorrimento delle barre trasversali possono essere di tipo noto con sezione a U e, pertanto facilmente reperibili sul mercato con conseguente abbattimento dei costi di fabbricazione. A further advantage consists in the fact that the sliding guides of the transverse bars can be of a known type with a U-section and, therefore, are easily available on the market with a consequent reduction in manufacturing costs.

Infine, un ulteriore vantaggio consiste nel fatto che per il sollevamento e conseguente impacchettamento, la grata non necessita di nessun cinematismo del tipo pignone-catena o puleggiacinghia. Finally, a further advantage consists in the fact that for lifting and consequent packing, the grate does not require any kinematics of the pinion-chain or belt pulley type.

Questi ed ulteriori vantaggi sono raggiunti dalla grata di sicurezza a scomparsa di cui alla presente invenzione, descritta in un’esecuzione preferita non limitativa di ulteriori sviluppi nell’ambito dell’invenzione stessa, con l’aiuto delle tavole di disegni allegate che illustrano le seguenti figure: These and further advantages are achieved by the retractable safety grating according to the present invention, described in a preferred embodiment that does not limit further developments within the scope of the invention itself, with the help of the attached drawings which illustrate the following figures:

fig. 1, una vista del dispositivo di trascinamento ed impacchettamento della grata all’interno di un cassonetto; fig. 2, una vista laterale di alcuni elementi costituenti la grata e di come questa è articolata; fig. 1, a view of the device for dragging and packing the grate inside a box; fig. 2, a side view of some elements making up the grating and how it is articulated;

fig. 3, una vista laterale di alcuni elementi della grata quando questa è impachettata; fig. 3, a side view of some elements of the grating when the latter is packaged;

fig. 4, una vista frontale del serramento, in posizione di chiusura, applicato ad una finestra. fig. 4, a front view of the window, in the closed position, applied to a window.

Con riferimento alle figure, la grata di sicurezza si compone di una serie di barre parallele trasversali 1 tra loro articolate, le cui estremità scorrono all’interno di una coppia di binari 4 disposte, verticalmente, su due lati opposti dell’apertura da proteggere. With reference to the figures, the safety grate consists of a series of parallel transverse bars 1 jointed together, the ends of which slide inside a pair of tracks 4 arranged vertically on two opposite sides of the opening to be protected.

Come illustrato nella figura 2, le barre trasversali 1 sono fra loro reciprocamente collegate ed articolate mediante piastrine 2 ciascuna impegnata, mediante una vite o qualsiasi altro mezzo idoneo, sulle sue due estremità ad altrettante barre 1. As shown in Figure 2, the transverse bars 1 are mutually connected and articulated by means of plates 2 each engaged, by means of a screw or any other suitable means, on its two ends to as many bars 1.

Allo scopo di consentire alla grata di sollevarsi e conseguentemente di impacchettarsi all’interno del cassonetto, la prima barra trasversale 1 è alloggiata, quando la grata è in posizione di massima estensione, all’interno di una delle tre semilune 6 ricavate su ciascuno dei due dischi 5 presenti alle estremità di un rullo riavvolgitore 7. In order to allow the grating to rise and consequently to pack itself inside the box, the first transverse bar 1 is housed, when the grating is in the maximum extension position, inside one of the three half-moons 6 obtained on each of the two discs 5 present at the ends of a rewinding roller 7.

Le semilune 6 sono fra loro equidistanti e, la loro distanza è la medesima che intercorre fra ciascuna barra trasversale 1. The half-moons 6 are equidistant from each other and their distance is the same as that between each transverse bar 1.

Allo scopo di consentire alle barre trasversali 1 di impacchettarsi in modo ordinato all’interno del cassonetto C la corsa circolare determinata dal disco 5 è prolungata e guidata da una guida superiore 8 ed una guida inferiore 9. In order to allow the transverse bars 1 to pack in an orderly manner inside the box C, the circular stroke determined by the disc 5 is extended and guided by an upper guide 8 and a lower guide 9.

Le barre 1 cadendo per gravità sulla base del cassonetto C si impachetteranno automaticamente, ovvero quest’ultimo potrà essere favorito applicando un’appendice alla prima delle suddette barre trasversali. The bars 1 falling by gravity on the base of the box C will automatically pack, or the latter can be favored by applying an appendix to the first of the aforementioned cross bars.
