METODO PER OTTENERE PALLET, E PALLET OTTENUTO CON TALE METODO. METHOD OF OBTAINING PALLETS, AND PALLET OBTAINED WITH THIS METHOD.

DESCRIZIONE DELL’INVENZIONE DESCRIPTION OF THE INVENTION

La presente invenzione si inserisce nel settore tecnico concernente la realizzazione di pallet, in particolare di cartone o materiale sintetico. The present invention is part of the technical sector concerning the production of pallets, in particular of cardboard or synthetic material.

Com'è noto, i tradizionali pallet di legno, largamente diffusi, presentano costi di produzione relativamente elevati e comportano, inoltre, notevoli problemi di raccolta e smaltimento. As is known, traditional wooden pallets, which are widely used, have relatively high production costs and also entail considerable collection and disposal problems.

L'accumulo a magazzino di tali pallet richiede, infatti, uno spazio adeguato e la loro eliminazione presenta costi non trascurabili. The storage of these pallets in the warehouse requires, in fact, adequate space and their elimination involves non-negligible costs.

Sono altresì noti dei pallet di cartone realizzati con la sovrapposizione e l'incollaggio, l’uno all’altro, di due fogli di cartone ondulato, dotati di opportune fustellature che definiscono una pluralità di alette ripiegabili, destinate a formare una serie ordinata di piedi di appoggio del pallet. Cardboard pallets are also known made by overlapping and gluing two sheets of corrugated cardboard to each other, equipped with suitable punching that define a plurality of foldable flaps, intended to form an ordered series of feet support of the pallet.

In pratica, dopo il ripiegamento rispetto al piano dei fogli di cartone, le alette citate definiscono le pareti laterali di una serie di elementi tubolari, a profilo sostanzialmente quadrato. In practice, after folding with respect to the plane of the cardboard sheets, the aforementioned fins define the side walls of a series of tubular elements, with a substantially square profile.

Per fornire ai piedi del pallet la necessaria robustezza, all’interno dei suddetti elementi tubolari vengono inseriti e incollati rispettivi elementi di forma scatolare; ulteriori elementi a forma di scatola vengono successivamente innestati e incollati all’esterno dei piedi. To provide the necessary strength at the foot of the pallet, respective box-shaped elements are inserted and glued inside the aforementioned tubular elements; further box-shaped elements are subsequently grafted and glued to the outside of the feet.

La soluzione menzionata é di attuazione complessa, giacché in particolare si deve procedere a un elaborato assemblaggio di parti da realizzare separatamente; tale complessità di realizzazione incide owiamente sui costi di produzione del pallet. Un metodo semplificato per la realizzazione di pallet di cartone prevede di praticare in un primo foglio di cartone un'ordinata pluralità di aperture rettangolari mediante relative linee di cordonatura e di taglio, in maniera da definire, in corrispondenza di ciascuna delle suddette aperture, una pluralità di alette ripiegabili. The aforementioned solution is of complex implementation, since in particular it is necessary to proceed with an elaborate assembly of parts to be made separately; this manufacturing complexity obviously affects the production costs of the pallet. A simplified method for making cardboard pallets provides for making an ordered plurality of rectangular openings in a first sheet of cardboard by means of relative creasing and cutting lines, so as to define, in correspondence with each of the aforementioned openings, a plurality of foldable flaps.

Nelle aperture vengono inseriti rispettivi piedi di appoggio ottenuti da elementi fustellati di cartone piegati in maniera da formare una sorta di scatola dotata di bordi ripiegati verso l’esterno; dette alette sono unite alla superficie esterna dei piedi di appoggio, risultando i piedi stessi sporgenti dal lato di ripiegamento delle alette e con i bordi sovrapposti al piano definito dalla faccia superiore del foglio di cartone. Al primo foglio di cartone viene unito un secondo foglio di cartone, dal lato opposto a quello da cui sono sporgenti i piedi di appoggio. Respective support feet are inserted into the openings obtained from cardboard die-cut elements folded to form a sort of box with edges folded outwards; said flaps are joined to the external surface of the support feet, resulting in the feet protruding from the folding side of the flaps and with the edges superimposed on the plane defined by the upper face of the cardboard sheet. A second cardboard sheet is joined to the first cardboard sheet, on the opposite side to that from which the support feet protrude.

Un altro metodo noto per la realizzazione di pallet di cartone prevede di praticare in un primo foglio di cartone una serie di aperture circonferenziali, in maniera da definire una pluralità di alette ripiegabili. Another known method for making cardboard pallets provides for making a series of circumferential openings in a first sheet of cardboard, so as to define a plurality of foldable flaps.

Nelle aperture vengono inseriti rispettivi piedi di appoggio ottenuti avvolgendo in forma tubolare una relativa striscia di cartone; i piedi sono uniti alle alette in maniera da risultare allineati alla sommità con il piano definito dalla faccia superiore del suddetto foglio di cartone. Respective support feet are inserted into the openings obtained by wrapping a relative strip of cardboard in a tubular form; the feet are joined to the fins so as to be aligned at the top with the plane defined by the upper face of the aforementioned sheet of cardboard.

Al primo foglio di cartone viene associato un secondo foglio di cartone, presentante una corrispondente serie di aperture circonferenziali che delimitano una pluralità di alette ripiegabili, atte ad essere unite alla superficie interna dei piedi tubolari. A second cardboard sheet is associated with the first cardboard sheet, having a corresponding series of circumferential openings which delimit a plurality of foldable flaps, suitable for being joined to the internal surface of the tubular feet.

I pallet realizzati secondo i metodi citati presentano una minore resistenza in corrispondenza della zona perimetrale del piano di carico, risultante a sbalzo rispetto ai piedi di appoggio. Ciò può limitarne le possibilità di impiego. The pallets made according to the aforementioned methods have a lower resistance in correspondence with the perimeter area of the loading surface, resulting in a cantilever with respect to the support feet. This may limit the possibilities of use.

E’, infatti, da sottolineare il fatto che i pallet di cartone ondulato devono comunque assicurare la necessaria resistenza, in rapporto all’impiego cui essi sono destinati. Un ulteriore metodo per la realizzazione di pallet, di cartone o materiale sintetico, consiste nell’associare a un piano di carico formato da due fogli di cartone ondulato 0 materiale sintetico, una serie di listelli sagomati costituiti da una successione di porzioni disposte a definire, su un piano orizzontale, un profilo a onda. In fact, it should be emphasized that the corrugated cardboard pallets must in any case ensure the necessary resistance, in relation to the use for which they are intended. A further method for making pallets, made of cardboard or synthetic material, consists in associating a loading surface formed by two sheets of corrugated cardboard or synthetic material with a series of shaped strips consisting of a succession of portions arranged to define, on a horizontal plane, a wave profile.

1 listelli sagomati sono interessati dal lato opposto del piano di carico da una serie di strisce di irrigidimento e presentano, inoltre, delle aperture per l'inserimento di mezzi sollevatori. The shaped strips are affected on the opposite side of the loading surface by a series of stiffening strips and also have openings for the insertion of lifting means.

Il pallet ottenuto risulta essere più resistente rispetto ai pallet descritti precedentemente, ma la realizzazione dello stesso risulta laboriosa. The pallet obtained is more resistant than the pallets described above, but its realization is laborious.

La prerogativa della presente invenzione è quella di realizzare un pallet di materiale sintetico, o cartone, secondo un metodo di facile attuazione e di costo economico, tale inoltre da assicurare un'elevata ed omogenea resistenza del piano di carico del pallet stesso. The prerogative of the present invention is that of making a pallet of synthetic material, or cardboard, according to a method which is easy to implement and of economic cost, which is also such as to ensure a high and homogeneous resistance of the loading surface of the pallet itself.

Un’ulteriore prerogativa dell’invenzione è proporre un metodo che permetta di ottenere un pallet che risulti agevolmente riciclabile dopo l'uso. A further prerogative of the invention is to propose a method that allows to obtain a pallet that is easily recyclable after use.

Un’altra prerogativa dell’invenzione è proporre un metodo che permetta di ottenere un pallet che può essere compresso in un volume limitato, prima di procedere allo smaltimento, così da ridurre sensibilmente l’ingombro a magazzino. Another prerogative of the invention is to propose a method that allows you to obtain a pallet that can be compressed into a limited volume, before proceeding with disposal, so as to significantly reduce the space in the warehouse.

Tali prerogative sono ottenute in accordo con quanto riportato nelle rivendicazioni.

The first sheet 1 has: first corner flaps 3, articulated, by means of transverse creases Ct, at each end of the corresponding transverse portions 1a, 1 b, of the same first sheet 1; articulated second corner pitches 30, by means of longitudinal creases CI, on the inner side 3a of the first corner pitches 3; first intermediate pitches 4, articulated, by means of transverse creases Ct, centrally to each transverse portion 1a, 1b; second and third intermediate pitches, 40, 41 respectively, with the second intermediate pitches 40 articulated, by longitudinal creases CI, to the sides 4a of the first intermediate pitches 4, and with the second pitches 41, also articulated by longitudinal creases CI to the remaining ones flanks 4b of said first intermediate flaps 4; a first central flap 5 obtained in the central portion 100 of the first sheet 1, articulated to the latter by means of a transverse creasing Ct; a second and a third central flap, 50, 51 respectively, with the second flap 50 articulated, by longitudinal creasing CI, to the corresponding side 5a of the first central flap 5, and with the third flap 51 also articulated, by longitudinal creasing CI to the remaining side 5b of said first central pitch 5.

Il primo foglio 1 , ad esempio come illustrato nella fig. 1a, è interessato, in entrambe le porzioni longitudinali 2a, 2b, da una serie di rientranze R, di cui sarà in seguito esplicata la funzione. The first sheet 1, for example as illustrated in fig. 1a, is affected, in both longitudinal portions 2a, 2b, by a series of recesses R, whose function will be explained below.

Il secondo foglio 2 presenta: prime alette d'angolo 6, articolate mediante cordonature longitudinali CI, ad ogni estremità longitudinale 2a, 2b, dello stesso secondo foglio 2; seconde alette d’angolo 7 articolate, mediante cordonature trasversali Ct, al fianco interno 6a delle prime alette d’angolo 6; prime alette intermedie 8 articolate mediante cordonature longitudinali CI centralmente in ogni porzione longitudinale 2a, 2b; seconde e terze alette intermedie, rispettivamente 9, 10, con le seconde alette 9 articolate, mediante cordonature trasversale Ct, ai fianchi 8a delle prime alette intermedie 8, e con le terze alette 10 articolate mediante cordonatura trasversale Ct, ai restanti fianchi 8b delle prime alette intermedie 8. In una seconda forma di realizzazione il pallet P è costituito da un primo foglio 1, un secondo foglio 2 ed un terzo foglio M da interporre tra detti primo e secondo foglio 1 , 2, per determinare una maggiore robustezza del pallet stesso. The second sheet 2 has: first corner flaps 6, articulated by longitudinal creases C1, at each longitudinal end 2a, 2b, of the same second sheet 2; second corner fins 7 articulated, by means of transverse creases Ct, on the inner side 6a of the first corner fins 6; first intermediate fins 8 articulated by longitudinal creases C1 centrally in each longitudinal portion 2a, 2b; second and third intermediate fins, 9, 10 respectively, with the second fins 9 articulated, by means of transverse creasing Ct, to the sides 8a of the first intermediate fins 8, and with the third fins 10 articulated by transversal creasing Ct, to the remaining sides 8b of the first intermediate flaps 8. In a second embodiment the pallet P consists of a first sheet 1, a second sheet 2 and a third sheet M to be interposed between said first and second sheets 1, 2, to determine greater strength of the pallet itself .

Tale foglio, ad esempio è realizzato con lo stesso materiale di detti primo e secondo foglio 1 , 2; inoltre, il foglio M è sprovvisto di falde e alette, ed è interessato da una serie di rientranze R1, ricavate lungo le porzioni longitudinali MI dello stesso foglio M e tali da essere sottostanti alle rientranze R del primo foglio. Said sheet, for example, is made of the same material as said first and second sheets 1, 2; moreover, the sheet M is devoid of flaps and flaps, and is affected by a series of recesses R1, obtained along the longitudinal portions M1 of the same sheet M and such as to be underneath the recesses R of the first sheet.

In una terza forma di realizzazione il pallet P1 è costituito da un primo foglio 1 e un secondo foglio 2, aventi parti identiche al pallet P descritto precedentemente e illustrato in fig. 1 (sono stati indicati con gli stessi riferimenti numerici le parti identiche di detti pallet P, P1). In a third embodiment, the pallet P1 consists of a first sheet 1 and a second sheet 2, having parts identical to the pallet P described above and illustrated in fig. 1 (the identical parts of said pallets P, P1 have been indicated with the same numerical references).

Il primo foglio 1 presenta in corrispondenza delle porzioni trasversali 1a, 1 b, e in corrispondenza della porzione centrale 100, una pluralità di falde 3, 30, 4, 40, 41 , 5, 50, 51 ; tale primo foglio 1 è, inoltre, provvisto di una prima patta 110a articolata, mediante cordonatura longitudinale G, alla porzione longitudinale 1c dello stesso primo foglio 1, e una seconda patta 110b articolata, mediante cordonatura longitudinale G, alla restante porzione longitudinale 1d di detto primo foglio 1. The first sheet 1 has a plurality of flaps 3, 30, 4, 40, 41, 5, 50, 51 in correspondence with the transverse portions 1a, 1 b, and in correspondence with the central portion 100; said first sheet 1 is also provided with a first flap 110a articulated, by longitudinal creasing G, to the longitudinal portion 1c of the same first sheet 1, and a second flap 110b articulated, by longitudinal creasing G, to the remaining longitudinal portion 1d of said first sheet 1.

Detto primo foglio 1 è interessato da incavi longitudinali di estremità 102, previsti in corrispondenza delle estremità T di dette porzioni longitudinali 1c, 1d, e di feritoie intermedie 103 previste centralmente a queste ultime, di cui sarà in seguito esplicata la funzione. Said first sheet 1 is affected by longitudinal end recesses 102, provided at the ends T of said longitudinal portions 1c, 1d, and by intermediate slits 103 provided centrally to the latter, the function of which will be explained below.

Il secondo foglio 2 presenta, in corrispondenza delle porzioni longitudinali 2a, 2b, una pluralità di alette 6, 7, 8, 9, 10, ed è, inoltre, provvisto di una prima striscia 200a articolata, mediante cordonatura trasversale N, alla porzione trasversale 2c dello stesso secondo foglio 2 e una seconda striscia 200b, articolata, mediante cordonatura trasversale N, alla restante porzione trasversale 2d, di detto secondo foglio 2. The second sheet 2 has, in correspondence with the longitudinal portions 2a, 2b, a plurality of fins 6, 7, 8, 9, 10, and is also provided with a first strip 200a articulated, by means of transverse creasing N, to the transverse portion 2c of the same second sheet 2 and a second strip 200b, articulated, by means of transverse creasing N, to the remaining transverse portion 2d, of said second sheet 2.

Al fianco esterno 201, di ognuna di dette prima e seconda striscia 200a, 200b, è articolato, mediante cordonatura longitudinale O, un primo lembo 221, mentre al restante fianco esterno 202, di ognuna di dette prima e seconda striscia 200a, 200b, è articolato, mediante cordonatura longitudinale O, un secondo lembo 222, di cui sarà in seguito esplicata la funzione. A first flap 221 is articulated to the outer side 201 of each of said first and second strips 200a, 200b, by longitudinal creasing 0, while the remaining outer side 202, of each of said first and second strips 200a, 200b, is articulated articulated, by longitudinal creasing 0, a second flap 222, the function of which will be explained below.

Per ottenere il pallet P è vantaggiosamente necessario fustellare il primo e il secondo foglio 1, 2, in modo tale che la cannettatura, o l’ondulazione, del materiale utilizzato sia, ad esempio, una longitudinale e una trasversale. To obtain the pallet P it is advantageously necessary to punch the first and second sheets 1, 2, so that the ribbing, or the corrugation, of the material used is, for example, a longitudinal and a transversal one.

I fogli ottenuti, dotati di opportune fustellature che definiscono una pluralità di alette ripiegabili, sono sovrapposti l'uno all’altro, come illustrato nella fig. 1C. The sheets obtained, equipped with appropriate punching that define a plurality of foldable flaps, are superimposed on each other, as shown in fig. 1C.

Successivamente tutte le falde associate al primo foglio 1 e tutte le alette del secondo foglio 2 sono piegate, ad esempio come illustrato in fig. 1 D, in modo tale da risultare perpendicolari a questi ultimi. Subsequently all the flaps associated with the first sheet 1 and all the flaps of the second sheet 2 are folded, for example as illustrated in fig. 1 D, in such a way as to be perpendicular to the latter.

Le rientranze R del primo foglio 1 e le rientranze R1 del terzo foglio M (se utilizzato) permettono, pertanto, alle prime alette d’angolo 6, e alle prime alette intermedie 8 di essere perfettamente perpendicolari rispetto al primo e secondo foglio 2, in quanto le rientranze consentono tale piegamento a 90°. The recesses R of the first sheet 1 and the recesses R1 of the third sheet M (if used) therefore allow the first corner flaps 6, and the first intermediate flaps 8 to be perfectly perpendicular to the first and second sheet 2, in how much the recesses allow such 90 ° bending.

I fianchi esterni 3b delle prime falde d’angolo 3 del primo foglio 1 sono a contatto con i fianchi esterni 6b delle prime alette d'angolo 6, associate al secondo foglio 2, e pertanto sono fissate per mantenere tale posizione. The external sides 3b of the first corner flaps 3 of the first sheet 1 are in contact with the external sides 6b of the first corner flaps 6, associated with the second sheet 2, and therefore are fixed to maintain this position.

Le seconde falde d’angolo 30 sono piegate verso l'interno, ad individuare tra le prime e le seconde falde d'angolo 3, 30, degli angoli acuti. The second corner pitches 30 are bent inwards, to identify acute angles between the first and second corner pitches 3, 30.

Le seconde alette d’angolo 7 sono piegate verso l’interno, in modo tale che le superfici interne Si di queste ultime sono a contatto e, quindi, fissate (con termosaldature, o collante, o mezzi noti esplicanti la medesima funzione), contro le superfici esterne Se delle seconde falde d’angolo 30, mentre i bordi interni Bi, Di, di queste ultime alette e falde, riscontrano la superficie esterna U del primo foglio 1 , e sono bloccati a definire, in corrispondenza delle quatto estremità del pallet P, i piedi K a base triangolare. The second corner flaps 7 are bent inwards, so that the internal surfaces Si of the latter are in contact and, therefore, fixed (with heat-sealing, or glue, or known means performing the same function), against the outer surfaces Se of the second corner flaps 30, while the inner edges Bi, Di, of the latter flaps and flaps, meet the outer surface U of the first sheet 1, and are locked to define, at the four ends of the pallet P, feet K with a triangular base.

Si piegano le seconde e terze falde intermedie 40, 41 , verso l’interno, in modo tale che i fianchi esterni 40b, 41 b, delle seconde e terze falde 41, 40, sono a contatto e, quindi, possono essere bloccati tra loro, mentre i bordi interni Di di dette falde riscontrano la superficie esterna U del primo foglio 1, bloccati a definire, in corrispondenza delle due porzioni centrali trasversali del pallet P, i piedi H a base triangolare. The second and third intermediate flaps 40, 41 are folded inwards, so that the external sides 40b, 41 b, of the second and third flaps 41, 40, are in contact and, therefore, can be locked together , while the internal edges Di of said flaps meet the external surface U of the first sheet 1, blocked to define, in correspondence with the two central transverse portions of the pallet P, the feet H with a triangular base.

Si piegano le seconde e terze alette intermedie 9, 10, verso l'interno, in modo tale che i fianchi esterni 9b, 10b, delle seconde e terze alette intermedie 9, 10, sono a contatto e, quindi, bloccate tra loro, mentre i bordi interni Bi di dette alette riscontrano la superficie esterna U del primo foglio 1 , e sono bloccati a definire, in corrispondenza delle due porzioni centrali longitudinali del pallet P, i piedi W a base triangolare. The second and third intermediate flaps 9, 10 are folded inwards, so that the outer sides 9b, 10b, of the second and third intermediate flaps 9, 10, are in contact and, therefore, locked together, while the internal edges Bi of said flaps meet the external surface U of the first sheet 1, and are blocked to define, in correspondence with the two central longitudinal portions of the pallet P, the feet W with a triangular base.

Sono, quindi, piegate le seconde e terze falde centrali 50, 51, verso l’interno, in modo tale che i fianchi 50b, 51 b, di dette falde sono a contatto e, quindi, possono essere bloccate tra loro; i bordi interni Di delle stesse falde sono a contatto con la superficie superiore E del secondo foglio 2, come illustrato nelle figure 1, 2, si definisce così, in corrispondenza del centro del primo foglio 1, un piede Z a base triangolare. Therefore, the second and third central flaps 50, 51 are bent inwards, so that the sides 50b, 51 b, of said flaps are in contact and, therefore, can be locked together; the inner edges Di of the same flaps are in contact with the upper surface E of the second sheet 2, as illustrated in Figures 1, 2, a foot Z with a triangular base is thus defined in correspondence with the center of the first sheet 1.

Per ottenere il pallet P1 è necessario: piegare le seconde alette d'angolo 7 (del secondo foglio 2), in modo tale da sovrapporle alle prime alette d'angolo 6 (sulla superficie esterna o sulla superficie interna di dette alette d’angolo 6); piegare le seconde e terze alette intermedie 9, 10, in modo tale da sovrapporle alle relative prime alette intermedie 8 (l’una sopra l'altra, con una delle due alette a contatto con le prime alette intermedie 8, o entrambe le alette intermedie 9, 10, a contatto con le prime alette intermedie 8); piegare, ulteriormente, le alette associate al secondo foglio 2 verso la superficie esterna U1 di detto primo foglio 1 ; far passare le alette d’angolo 6, 7, (opportunamente piegate) negli incavi longitudinali di estremità 102, e le alette intermedie 8, 9, 10, (opportunamente piegate) nelle feritoie intermedie 103, a determinare il combaciamento del primo e del secondo foglio 1 , 2; piegare le falde associate al primo foglio 1 verso la superficie esterna U1 di quest’ultimo; piegare la prima e seconda striscia 200a, 200b, verso la superficie interna I del secondo foglio 2 e i lembi 221 , 222, verso le superfici interne SI di dette prima e seconda striscia, ad esempio a definire con queste ultime degli angoli di 90°; piegare la prima e la seconda patta 1 10a, 110b, verso la superficie interna I del secondo foglio 2, bloccando le estremità D di dette patte 110a, 110b, alla superficie esterna di detti primi e secondi lembi 221, 221 , a definire, in combinazione con la prima e la seconda striscia 200a, 200b, un bordo rialzato 400; piegare le falde associate al primo foglio 1 e le alette associate al secondo foglio 2, come descritto precedentemente per il pallet P, a definire una serie ordinata di piedi K, H, W, Z. Nella figg. 5, è illustrata una seconda forma di realizzazione dei piedi intermedi H, W, Z, mentre nella fig. 6 una seconda forma di realizzazione dei piedi d'angolo K. I piedi H, come illustrato in figura 5, sono costituiti da: prime falde intermedie 4; seconde e terze falde intermedie, rispettivamente 40, 41 ; prime linguette 401, articolate, mediante cotonature longitudinali G, a fianchi esterni di dette seconde falde intermedie 40; seconde linguette 410, articolate, mediante cordonature longitudinali G, ai fianchi esterni di dette terze falde intermedie 41. To obtain pallet P1 it is necessary: to fold the second corner fins 7 (of the second sheet 2), so as to overlap them with the first corner fins 6 (on the external surface or on the internal surface of said corner fins 6 ); fold the second and third intermediate flaps 9, 10, so as to overlap the relative first intermediate flaps 8 (one on top of the other, with one of the two flaps in contact with the first intermediate flaps 8, or both intermediate flaps 9, 10, in contact with the first intermediate fins 8); further folding the flaps associated with the second sheet 2 towards the outer surface U1 of said first sheet 1; pass the corner fins 6, 7, (suitably bent) in the longitudinal end grooves 102, and the intermediate fins 8, 9, 10, (suitably bent) in the intermediate slots 103, to determine the mating of the first and the second sheet 1, 2; fold the flaps associated with the first sheet 1 towards the external surface U1 of the latter; folding the first and second strips 200a, 200b, towards the internal surface I of the second sheet 2 and the edges 221, 222, towards the internal surfaces S1 of said first and second strips, for example to define angles of 90 ° with the latter; fold the first and second flaps 10a, 110b, towards the inner surface I of the second sheet 2, locking the ends D of said flaps 110a, 110b, to the outer surface of said first and second flaps 221, 221, to define, in combination with the first and second strips 200a, 200b, a raised edge 400; fold the flaps associated with the first sheet 1 and the flaps associated with the second sheet 2, as previously described for the pallet P, to define an ordered series of feet K, H, W, Z. In figs. 5, a second embodiment of the intermediate feet H, W, Z is shown, while in fig. 6 a second embodiment of the corner feet K. The feet H, as illustrated in Figure 5, consist of: first intermediate flaps 4; second and third intermediate layers, respectively 40, 41; first tongues 401, articulated, by means of longitudinal backing G, to the external sides of said second intermediate flaps 40; second tabs 410, articulated, by means of longitudinal creases G, to the external sides of said third intermediate flaps 41.

Tali prime e seconde linguette sono previste per agevolare il bloccaggio delle citate falde a definire il sopraccitato piede H. These first and second tabs are provided to facilitate the locking of the aforementioned flaps to define the aforementioned foot H.

I restanti piedi intermedi Z, W, sono anch’essi provvisti di prime e seconde linguette 401, 410, articolate come sopra descritto alle corrispondenti falde per il piede Z, e ai fianchi esterni delle seconde e terze alette 9, 10, per i piedi W. The remaining intermediate feet Z, W, are also provided with first and second tabs 401, 410, articulated as described above to the corresponding flaps for the foot Z, and to the external sides of the second and third tabs 9, 10, for the feet W.

Nella fig. 6, è illustrata una seconda forma di realizzazione dei piedi d’angolo K. Nella variante illustrata le prime faide d’angolo 3 hanno una larghezza Y decrescente fino ad arrivare ad un minimo in corrispondenza delle estremità 3c delle stesse prime falde 3, e le prime alette d’angolo 6 hanno una larghezza J decrescente fino ad arrivare ad un minimo in corrispondenza delle estremità 6c delle stesse prime alette 6. In fig. 6, a second embodiment of the corner feet K is shown. In the variant illustrated the first corner feuds 3 have a decreasing width Y up to a minimum at the ends 3c of the same first pitches 3, and the first corner fins 6 have a decreasing width J up to a minimum at the ends 6c of the same first fins 6.

Le falde d’angolo 3 e le alette d’angolo 6 definiscono, in combinazione con le citate seconde falde d’angolo 30 e le citate seconde alette d’angolo 7, dei piedi troncoconici con sezione triangolare; è possibile ottenere in funzione delle dimensioni di tali falde e alette, del loro numero, e della loro mutua disposizione, piedi tronco conici a sezione rettangolare. The corner flaps 3 and the corner flaps 6 define, in combination with the aforementioned second corner flaps 30 and the aforementioned second corner flaps 7, truncated cone feet with a triangular section; it is possible to obtain truncated cone feet with rectangular section according to the size of these flaps and fins, their number and their mutual arrangement.

In seguito alla definizione dei piedi K, H, W, Z, per aumentare la robustezza del pallet P è possibile fissare a tutti i piedi K-H e W-Z, delle fasce d’irrigidimento trasversale Ft; mentre a tutti i piedi K-W, e H-Z, si possono fissare delle fasce d'irrigidimento longitudinali FI, ad esempio sulla superficie di appoggio Sa di detti piedi. Following the definition of the feet K, H, W, Z, to increase the strength of the pallet P, it is possible to fix transversal stiffening bands Ft to all the feet K-H and W-Z; while to all the feet K-W, and H-Z, longitudinal stiffening bands FI can be fixed, for example on the supporting surface Sa of said feet.

Evidenziamo che nella in fig. 2 è stata illustrata solo una fascia di irrigidimento trasversale Ft e solo una longitudinale FI. We highlight that in fig. 2 only one transverse stiffening band Ft and only one longitudinal FI has been shown.

Per aumentare la superficie di appoggio Sa dei pallet si possono, inoltre, calzare e bloccare ad ognuno dei piedi ottenuti come sopra descritto, corrispondenti cappucci 20, complementari al profilo di detti piedi e presentanti una superficie 20a maggiore di quella di appoggio Sa. To increase the support surface Sa of the pallets, corresponding caps 20, complementary to the profile of said feet and having a surface 20a greater than the support surface Sa, can also be fitted and locked to each of the feet obtained as described above.

Il pallet P ottenuto, come precedentemente descritto, risulta essere particolarmente vantaggioso, in quanto l’ottenimento dello stesso è molto rapido e semplice. The pallet P obtained, as previously described, is particularly advantageous, as obtaining it is very quick and simple.

E’ necessario, infatti, far combaciare il primo e il secondo foglio 1 , 2, tra cui inserire eventualmente almeno un terzo foglio M, precedentemente fustellati e cordonati ad ottenere una pluralità di falde nel primo foglio 1 e una pluralità di alette nel secondo foglio 2. In fact, it is necessary to make the first and second sheet 1, 2 match, including possibly inserting at least a third sheet M, previously punched and creased to obtain a plurality of flaps in the first sheet 1 and a plurality of flaps in the second sheet 2.

In seguito al combaciamento di detti fogli è solamente necessario piegare le falde e le alette come sopra descritto e bloccarle, secondo tecniche note, a definire i piedi H, K, W, Z. Following the mating of said sheets it is only necessary to fold the flaps and the flaps as described above and lock them, according to known techniques, to define the feet H, K, W, Z.

Il fatto di prevedere il pallet P costituito, come illustrato nella fig. 1, dal primo e dal secondo foglio 1, 2, o, come illustrato nella fig. 3, dal primo, dal secondo e dal terzo foglio 1, 2, M, rende lo stesso pallet assemblabile da chiunque e, pertanto, non è richiesto del personale qualificato: ciò comporta un notevole vantaggio, in quanto è possibile consegnare agli utilizzatori i fogli 1, 2, M, opportunamente imballati, con la conseguente diminuzione dei costi sostenuti per le spedizioni e l’accatastamento a magazzino. The fact of providing the constituted pallet P, as illustrated in fig. 1, from the first and second sheets 1, 2, or, as illustrated in FIG. 3, from the first, second and third sheet 1, 2, M, makes the same pallet assembled by anyone and, therefore, no qualified personnel is required: this entails a considerable advantage, as it is possible to deliver the sheets to users 1, 2, M, suitably packaged, with the consequent decrease in costs incurred for shipments and stacking in the warehouse.

Con l’impiego di fogli di materiale sintetico, o di cartone ondulato, si riduce sensibilmente l’ingombro a magazzino, in quanto il pallet può essere compresso in un volume limitato, prima di procedere allo smaltimento. With the use of sheets of synthetic material, or corrugated cardboard, the space in the warehouse is significantly reduced, as the pallet can be compressed into a limited volume, before proceeding with disposal.

Il fatto, inoltre, di utilizzare un materiale sintetico, o di cartone, rende il pallet P facilmente riciclabile in seguito allo smaltimento. Furthermore, the fact of using a synthetic material, or cardboard, makes pallet P easily recyclable following disposal.

Il fatto di prevedere delle fasce di irrigidimento longitudinali e trasversali rende il pallet molto robusto; mentre l'utilizzo di cappucci 20 permette di aumentare la superficie di appoggio dello stesso pallet P rendendo quest’ultimo particolarmente resistente alle sollecitazioni. The fact of providing longitudinal and transversal stiffening bands makes the pallet very sturdy; while the use of caps 20 allows to increase the support surface of the pallet P itself, making the latter particularly resistant to stress.

Nelle forme di realizzazione di cui alle fig.1-3 i piedi hanno forma cilindrica con sezione triangolare; è possibile ottenere in funzione delle relative falde e alette che li definiscono, delle loro dimensioni, del loro numero, e della loro mutua disposizione, piedi tronco conici a sezione rettangolare. In the embodiments of fig. 1-3 the feet have a cylindrical shape with a triangular section; it is possible to obtain truncated cone feet with rectangular section according to the relative flaps and fins that define them, their dimensions, their number and their mutual arrangement.

Si intende che quanto sopra è stato descritto a titolo esemplificativo, e non limitativo, per cui eventuali variazioni di natura pratico applicativa s'intendono rientranti neH’ambito protettivo come sopra descritto e nel seguito rivendicato. It is understood that the above has been described by way of example, and not as a limitation, for which any variations of a practical applicative nature are understood to fall within the protective scope as described above and claimed hereinafter.
