Compito del presente trovato è quello di realizzare una cerniera perfezionata che risulti più compatta e di peso ridotto, rispetto alla cerniere di tipo noto, The aim of the present invention is to provide an improved hinge which is more compact and of reduced weight, with respect to known hinges,
NeH’ambito di questo compito, uno scopo del trovato è quello di realizzare una cerniera costituita da un numero ridotto di componenti ed il cui costo di produzione risulti più economico, rispetto alle cerniere di tipo tradizionale . Within the scope of this aim, an object of the invention is to provide a hinge consisting of a reduced number of components and whose production cost is cheaper than traditional hinges.
Questo ed altri scopi, che meglio appariranno evidenziati in seguito, sono raggiunti da una cerniera, per coperchi di cucine, per antine e per sportelli in genere, caratterizzata dal fatto di comprendere una testina di attacco che si inserisce a pressione in un profilato dotato di una cavità sagomata, in modo da consentire una rotazione parziale del coperchio di una cucina, il quale è applicato al suddetto profilato; la cerniera presenta mezzi elastici atti a sopportare almeno parzialmente il peso del coperchio, mezzi di limitazione della rotazione del coperchio, rispetto al supporto, e mezzi di ritegno dell'elemento elastico; i mezzi di ritegno dell'elemento elastico sono costituiti da un nottolino cooperante con una rondella di ritegno sagomata. This and other purposes, which will appear more clearly later on, are achieved by a hinge, for kitchen lids, for doors and for doors in general, characterized by the fact that it comprises an attachment head which is inserted by pressure into a profile equipped with a shaped cavity, so as to allow a partial rotation of the lid of a cooker, which is applied to the aforementioned profile; the hinge has elastic means able to at least partially support the weight of the lid, means for limiting the rotation of the lid, with respect to the support, and means for retaining the elastic element; the retaining means of the elastic element consist of a pawl cooperating with a shaped retaining washer.
Ulteriori caratteristiche e vantaggi dell'oggetto del presente trovato risulteranno maggiormente evidenziati attraverso un esame della descrizione di una forma di realizzazione preferita, ma non esclusiva, del trovato, illustrata a titolo indicativo e non limitativo nei disegni allegati, in cui: Further characteristics and advantages of the object of the present invention will become more evident through an examination of the description of a preferred, but not exclusive, embodiment of the invention, illustrated by way of non-limiting example in the attached drawings, in which:
la figura 1 è una vista prospettica in esploso della struttura di cerniera, secondo il trovato; Figure 1 is an exploded perspective view of the hinge structure according to the invention;
la figura 2 è una vista in alzato laterale di un coperchio, dotato della cerniera secondo il presente trovato, illustrato in posizione aperta; Figure 2 is a side elevation view of a lid, equipped with the hinge according to the present invention, shown in the open position;
la figura 3 è una vista in alzato frontale, parzialmente sezionata, la quale illustra il coperchio in posizione chiusa; Figure 3 is a partially sectioned front elevation view showing the lid in closed position;
la figura 4 è una vista in alzato laterale, dalla parte opposta ed ingrandita, rispetto alla figura 2, Figure 4 is a side elevation view, from the opposite side and enlarged, with respect to Figure 2,
la figura 5 è una vista simile alla precedente, ma che illustra il coperchio in posizione chiusa; Figure 5 is a view similar to the previous one, but showing the lid in the closed position;
le figure 6 e 7 sono viste in alzato laterale, ingrandite rispetto alle precedenti, le quali illustrano la cerniera sezionata secondo due diversi piani di sezione. Figures 6 and 7 are side elevation views, enlarged with respect to the previous ones, which illustrate the hinge sectioned according to two different section planes.
Con particolare riferimento ai simboli numerici delle suddette figure, la cerniera, secondo il trovato, indicata globalmente con il numero di riferimento 1, comprende una testina di attacco 2, la cui forma può essere diversa a seconda delle esigenze, la quale si inserisce a pressione in un profilato 3, dotato di una cavità sagomata 4, in modo da consentire una rotazione parziale del coperchio 5 di una cucina o di antine e di sportelli in genere, With particular reference to the numerical symbols of the aforementioned figures, the hinge, according to the invention, globally indicated with the reference number 1, comprises an attachment head 2, the shape of which can be different according to requirements, which is inserted by pressure in a profile 3, equipped with a shaped cavity 4, so as to allow a partial rotation of the lid 5 of a kitchen or of doors and doors in general,
Il coperchio 5 è applicato al suddetto profilato 3 ,il quale è a sua volta supportato da un montante 20 attraverso la cerniera 1 . The cover 5 is applied to the aforementioned section 3, which is in turn supported by an upright 20 through the hinge 1.
La testina di attacco 2 presenta un colletto 6 dotato di una sporgenza 7, la quale può ruotare in una gola 8 di un angolo definito dai dentini finecorsa 9, The attachment head 2 has a collar 6 provided with a protrusion 7, which can rotate in a groove 8 by an angle defined by the limit switch teeth 9,
La suddetta testina 2 presenta, inoltre, un perno, o alberino centrale 10, sul quale è montata coassialmente una molla elicoidale 11. The aforementioned head 2 also has a pin, or central shaft 10, on which a helical spring 11 is coaxially mounted.
La molla elicoidale 11 è dotata di una prima estremità assiale 12, che si inserisce in un foro 13 praticato nel colletto 6 della testina 2 The helical spring 11 is equipped with a first axial end 12, which fits into a hole 13 made in the collar 6 of the head 2
La stessa molla elicoidale 11 è dotata di una seconda estremità assiale 14 che si inserisce in un foro 15, praticato in un nottolino 16 che funge anche da camma, The helical spring 11 itself is equipped with a second axial end 14 which fits into a hole 15, made in a pawl 16 which also acts as a cam,
Il nottolino 16 è provvisto di un dente terminale sporgente 17 e di due denti periferici 18 The pawl 16 is provided with a protruding terminal tooth 17 and two peripheral teeth 18
I denti periferici 18 si impegnano nel profilato cavo 3 in cui è inserita la cerniera 1, consentendo una rotazione relativa di un angolo definito dai dentini finecorsa 9 , The peripheral teeth 18 engage in the hollow section 3 in which the hinge 1 is inserted, allowing a relative rotation of an angle defined by the limit switch teeth 9,
II dente terminale sporgente 17 impegna una rondella sagomata 19, la quale viene bloccata assialmente sull'alberino centrale 10 mediante deformazione meccanica. The protruding terminal tooth 17 engages a shaped washer 19, which is axially blocked on the central shaft 10 by mechanical deformation.
L’alberino centrale 10 presenta una sezione poligonale, o comunque irregolare, in modo da non consentire la rotazione relativa della rondella di ritegno 19. The central shaft 10 has a polygonal section, or in any case irregular, so as not to allow the relative rotation of the retaining washer 19.
Il nottolino 16 è montato sull’alberino 10 ed è dotato di un diametro tale da permettere la sua rotazione attorno all’alberino stesso, The pawl 16 is mounted on the shaft 10 and is equipped with a diameter such as to allow it to rotate around the shaft itself,
La rondella 19 consente una rotazione limitata del nottolino 16, impedendo la fuoriuscita della molla 11, in direzione assiale lungo l’alberino 10, ed impedendo la controrotazione della molla stessa, la quale viene precaricata in base alla posizione geometrica del finecorsa 9 in fase di produzione della cerniera. The washer 19 allows a limited rotation of the pawl 16, preventing the spring 11 from coming out, in the axial direction along the shaft 10, and preventing the counter-rotation of the spring itself, which is preloaded according to the geometric position of the limit switch 9 in the phase of production of the hinge.
Si è in pratica constatato che il trovato raggiunge il compito e gli scopi prefissati. In practice it has been found that the invention achieves the intended aim and objects.
Si è infatti realizzata una cerniera più compatta e costituita da un numero ridotto di componenti, rispetto alle cerniere di tipo noto, In particolare, la cerniera secondo il presente trovato comprende mezzi di ritegno della molla, costituiti da un nottolino centrale alleggerito e da una semplice rondella di ritegno, a differenza dei sistemi precedenti che richiedevano un nottolino centrale più grande ed un secondo nottolino di ritegno cooperante con una rondella di bloccaggio. In fact, a more compact hinge has been made, consisting of a reduced number of components, compared to hinges of the known type. In particular, the hinge according to the present invention comprises spring retaining means, consisting of a lightened central pawl and a simple retaining washer, unlike previous systems which required a larger central pawl and a second retaining pawl cooperating with a lock washer.
Naturalmente i materiali impiegati, nonché le dimensioni, potranno essere qualsiasi, secondo le esigenze. The materials used, as well as the dimensions, may of course be any according to requirements.
