DESCRIZIONE DEL MODELLO DI UTILITÀ’ DAL TITOLO “BASETTA SNODABILE FISSA O REGOLABILE IN ALTEZZA E SCOMPONIBILE” DESCRIPTION OF THE UTILITY MODEL WITH THE TITLE "FIXED OR HEIGHT ADJUSTABLE AND DETACHABLE HINGED BASE"

Sovente capita di dovere poggiare su piani carichi di media entità che devono essere ripartiti mediante apposite piastre di appoggio per contenere la tensione di contatto sul piano di appoggio entro i limiti prestabiliti in funzione della natura e delle caratteristiche del piano d’appoggio; gualora il piano d’appoggio è orizzontale tale situazione normalmente non presenta particolari problematiche, ma se il piano di appoggio presenta inclinazione prevalente ed una secondaria (inclinazione del piano di appoggio sia in direzione X che Y) allora nasce il problema di come trasferire l’azione al piano di appoggio in modo razionale e nei limiti di accettabilità in base alle caratteristiche del citato piano di appoggio. Often it happens to have to rest on medium-sized load surfaces that must be distributed by means of special support plates to contain the contact voltage on the support surface within the predetermined limits according to the nature and characteristics of the support surface; If the support surface is horizontal, this situation does not normally present particular problems, but if the support surface has a prevalent inclination and a secondary one (inclination of the support surface both in X and Y direction) then the problem arises of how to transfer the action on the support surface in a rational way and within the limits of acceptability based on the characteristics of the aforementioned support surface.

L’oggeto del presente brevetto ha appunto lo scopo di risolvere tale particolare problematica in modo semplice funzionale razionale e nel rispeto delle caratteristiche del piano di appoggio, trasferendo sul piano sia carichi di piccola e media entità che carichi anche elevati. The object of this patent has precisely the purpose of solving this particular problem in a simple functional and rational way and in compliance with the characteristics of the support surface, transferring both small and medium loads and even high loads to the surface.

L’oggetto in guestione definito appunto “BASETTA SNODABILE FISSA 0 REGOLABILE IN ALTEZZA E SCOMPONIBILE", è in grado di conferire particolare efficacia o comodità di impiego ed utilizzo a strutture, macchine utensili ed oggetti per conferirgli particolare efficacia e/o comodità di impiego e configurazione ed è pertanto inguadrabile nella fattispecie di “Modello di Utilità”: come rilevabile nelle TAVOLE GRAFICHE 1 e 2, si compone sostanziaimente di tre componenti e precisamente: The object in guestione defined precisely "FIXED OR HEIGHT ADJUSTABLE HINGED BASE", is able to give particular effectiveness or ease of use and use to structures, machine tools and objects to give them particular effectiveness and / or ease of use and configuration and therefore cannot be used in the case of a "Utility Model": as can be seen in GRAPHIC TABLES 1 and 2, it essentially consists of three components, namely:

> Basamento snodabile ‘A’ che, in unico pezzo comprende la piastra in acciaio di forma quadrata o circolare Ά3’ in grado dì poggiare sul piano di appoggio anche inclinato e, in posizione centrata, da un rialzo verticale in acciaio ‘A2’ provvisto di una sede semisferica Ά1’ idonea per ricevere l’apposito elemento sferico posto alla base del supporto verticale ‘B.a’ o ’B.b’: l’accoppiamento tra la sfera 'B.a1' o ‘B.b1 ' del supporto verticale, nella sede Ά1’ del basamento snodabile ‘A’ consente di mantenere l'orizzontalità dell’elemento ‘B.a2’ o ‘B.b2’ del supporto verticale e la conseguente verticalità dell’elemento ‘B.a3’ o ‘B.b3’ ad esso collegato, mentre il basamento snodabile ruoterà intorno al centro geometrico dell’accoppiamento tra ‘B.a1’ o ‘B.b1’ e Ά1’ consentendo alla piastra ‘A3’ del basamento di adagiarsi sul piano di appoggio inclinato in modo complanare ad esso, seguendone l’inclinazione sia nella direzione X che in quella Y. > Articulated base 'A' which, in a single piece, includes the square or circular steel plate Ά3 'capable of resting on the support surface even inclined and, in a centered position, by a vertical steel' A2 'rise equipped with a hemispherical seat Ά1 'suitable to receive the special spherical element placed at the base of the vertical support' B.a 'or' B.b ': the coupling between the ball' B.a1 'or' B.b1 'of the support vertical, in the seat Ά1 'of the articulated base' A 'allows to maintain the horizontality of the element' B.a2 'or' B.b2 'of the vertical support and the consequent verticality of the element' B.a3 'or' B .b3 'connected to it, while the articulated base will rotate around the geometric center of the coupling between' B.a1 'or' B.b1 'and Ά1' allowing the base plate 'A3' to rest on the inclined support surface in coplanar to it, following its inclination both in the X and in the Y direction.

Nella piastra in acciaio Ά3’ del basamento snodabile sono inoltre presenti quattro forature ‘A4’ necessarie per bloccare il basamento snodabile al piano di appoggio mediante tassellatura per contrastare scivolamenti. Supporto verticale ‘B’ che può essere di due distinte tipologie, ovvero per posizionamenti fissi ‘B.a’ o regolabili in altezza ‘B.b’, entrambi compatibili ad essere assemblati con le rimanenti parti. Sia il supporto fisso ‘B.a’ che quello regolabile in altezza ’B.b’ in un unico pezzo comprendono rispettivamente una sfera in acciaio ‘B.a1’ o ‘B.b1 ’ privata nella parte superiore di una piccola calotta per realizzare una sede piana per collocarvi, adeguatamente saldato, l’elemento piano con pianta circolare e sezione troncoconica ‘B.a2’ o ‘B.b2’ sul quale vincolare con specifica saldatura l’elemento di raccordo in grado di ricevere mediante accoppiamento l’asta sulla quale agisce l’azione da trasferire al piano di appoggio; per l’utilizzo nei ponteggi metallici fissi in acciaio l’elemento di raccordo per posizionamenti fissi è rappresentato da un tubo in acciaio liscio ‘B.a3’ (lunghezza 15-20 cm) ove collocare coassialmente la base del montante tubolare del ponteggio, mentre per posizionamenti regolabili in altezza l’elemento di raccordo è rappresentato da un tubo filettato ‘B.b3’ (lunghezza 30-80 cm) con ghiera filettata di regolazione ‘B.b4’ necessaria per regolare l’altezza verticale del montante tubolare del ponteggio collocato coassialmente al tubo filettato superiormente alla ghiera: per ambedue le tipologie di supporti verticali (fisso ‘B.a’ o regolabile ‘B.b’) il montante del ponteggio una volta accoppiato coassialmente nell’elemento ‘B.a3’ o ‘B.b3’ del supporto verticale trasferirà l’azione per mezzo dell’elemento ‘B.a2’ o ‘B.b2’ del supporto verticale, e di conseguenza in cascata, tramite gli elementi ‘B.a1’ o<1>B.b1\ e successivamente mediante Ά1’, Ά2’ e ‘A3’ verrà trasferito al piano di appoggio. Per altre tipologie di utilizzo, l’elemento di accoppiamento 'B.a' o ‘B.b’ del supporto verticale sarà modellato in modo adeguato per l’adattamento all’elemento a cui si intende accoppiare per mantenerlo verticale; In the steel plate Ά3 'of the articulated base there are also four' A4 'holes necessary to lock the articulated base to the support surface by means of anchoring to prevent slipping. Vertical support 'B' which can be of two distinct types, or for fixed positioning 'B.a' or height-adjustable 'B.b', both compatible to be assembled with the remaining parts. Both the fixed support 'B.a' and the height-adjustable one-piece 'B.b' comprise respectively a steel sphere 'B.a1' or 'B.b1' private in the upper part of a small cap to realize a flat seat to place, adequately welded, the flat element with circular plan and truncated cone section 'B.a2' or 'B.b2' on which to constrain with specific welding the connecting element capable of receiving the rod by coupling on which the action to be transferred to the support surface acts; for use in fixed metal scaffolding in steel, the connecting element for fixed positioning is represented by a smooth steel tube 'B.a3' (length 15-20 cm) where the base of the tubular upright of the scaffolding is coaxially placed, while for height-adjustable positioning the connecting element is represented by a threaded tube 'B.b3' (length 30-80 cm) with threaded adjustment ring nut 'B.b4' necessary to adjust the vertical height of the tubular upright of the scaffolding placed coaxially to the threaded tube above the ring nut: for both types of vertical supports (fixed 'B.a' or adjustable 'B.b') the upright of the scaffold once coupled coaxially in element 'B.a3' or 'B .b3 'of the vertical support will transfer the action through the element' B.a2 'or' B.b2 'of the vertical support, and consequently in cascade, through the elements' B.a1' or <1> B. b1 \ and subsequently by means of Ά1 ', Ά2' and 'A3' will be transferred to the support plane I. For other types of use, the coupling element 'B.a' or 'B.b' of the vertical support will be modeled appropriately for adaptation to the element to which it is intended to be coupled to keep it vertical;

Piastra di blocco ‘C’ costituita da un doppio piatto in acciaio con le medesime dimensioni in pianta del rialzo del basamento snodabile con foratura centrale ‘C1 ’ compatibile sia con la sfera ‘B.a1’ o B.b1’ del supporto verticale che con la sede Ά1’ del basamento snodabile, con raggio variabile lunqo lo spessore della foratura ‘C1’, costituito da due parti simmetriche che verranno bloccate al basamento snodabile mediante 4 bulloni con testa conica a scomparsa (prigionieri) inseriti nelle quattro sedi ‘C2’ della piastra di blocco ‘C’ ed ancorati alle quattro forature filettate Ά5’ poste nel rialzo Ά2’ del basamento snodabile ‘A’, ed il cui scopo è quello di impedire che il supporto verticale ‘B.a1’ o ‘B.b1’ possa fuoriuscire dalla sede ‘A3’ posta nel basamento snodabile ‘A’, ma consentire solo le rotazioni. Block plate 'C' consisting of a double steel plate with the same dimensions in plan as the rise of the articulated base with central hole 'C1' compatible with both ball 'B.a1' or B.b1 'of the vertical support and with the seat Ά1 'of the articulated base, with variable radius along the thickness of the hole' C1 ', consisting of two symmetrical parts that will be locked to the articulated base by means of 4 bolts with concealed conical head (studs) inserted in the four seats' C2' of the block plate 'C' and anchored to the four threaded holes Ά5 'placed in the rise Ά2' of the articulated base 'A', and whose purpose is to prevent the vertical support 'B.a1' or 'B.b1' from come out of the seat 'A3' placed in the articulated base 'A', but allow only the rotations.

Per consentire i movimenti del basamento snodabile ‘A’ rispetto al supporto verticale ‘B’ è necessario che i raqqi di curvatura deqli elementi che si accoppiano definiti ‘B.a1’ o ‘B.b1 ’ ed Ά1’ siano tra loro conqruenti e compatibili nel senso che il raggio dell’elemento<*>B1 ’ deve essere di alcuni decimi di millimetro inferiore del raggio della sede A1’ di alloggiamento e che nello stesso tempo la curvatura verticale interna delia foratura ‘C1’ presente dell’elemento di blocco ‘C’ sia la medesima di quella della sede ‘A1’ del basamento snodabile, ovvero i due pezzi, una volta assemblati e bloccati devono mantenere una continuità della superficie interna nella sede ‘A1’ e nella sede ‘C1’. To allow the movements of the articulated base 'A' with respect to the vertical support 'B' it is necessary that the curvature raqqs of the elements that couple defined 'B.a1' or 'B.b1' and Ά1 'are mutually consistent and compatible in the sense that the radius of the element <*> B1 'must be a few tenths of a millimeter lower than the radius of the housing seat A1' and that at the same time the internal vertical curvature of the hole 'C1' present in the locking element ' There is the same as that of the seat 'A1' of the articulated base, i.e. the two pieces, once assembled and locked, must maintain a continuity of the internal surface in the seat 'A1' and in the seat 'C1'.

Ad assemblaggio effettuato il supporto verticale ‘B.a’ o ‘B.b’ non può più fuoriuscire dalla sede A1 dei basamento snodabile grazie all’azione dell’elemento di blocco ‘C’, mentre la piccola lama d’aria che resta tra sede di alloggiamento ‘A1’ Ό1’ e l’elemento 'B.a1' o ’B.bl<1>deve consentire le rotazioni previste al fine di mantenere la orizzontalità dell’elemento ‘B.a2’ o B.b2’ del supporto verticale e la conseguente verticalità dell’elemento ‘B.a3’ o ‘B.b3’ ad esso vincolato, rispetto alla piastra ‘A3’ del basamento snodabile TV che potendo ruotare asseconderà nel movimento il piano di appoggio comunque inclinato, nei limiti previsti, assumendone la medesima inclinazione. Once assembled, the vertical support 'B.a' or 'B.b' can no longer protrude from the seat A1 of the articulated base thanks to the action of the locking element 'C', while the small air curtain that remains between housing seat 'A1' Ό1 'and element' B.a1 'or' B.bl <1> must allow the foreseen rotations in order to maintain the horizontality of element 'B.a2' or B.b2 'of the vertical support and the consequent verticality of the element 'B.a3' or 'B.b3' bound to it, with respect to the plate 'A3' of the articulated TV base which, being able to rotate, will support the movement of the supporting surface, however inclined, within the limits provided , assuming the same inclination.

Nella TAVOLA GRAFICA 3 è rappresentato l’intero componente, sia nella configurazione fissa che in quella regolabile in altezza, con le tre parti assemblate secondo una vista frontale che ovviamente è sostanzialmente uguale per nei piani X-Z e Y-Z a seguito della simmetria: nel grafico globale è possibile visionare la rotazione massima ottenibile dal basamento snodabile, nonché la identificazione dei vari elementi che la compongono secondo le indicazioni riportate nella superiore descrizione specificatamente evidenziate nelle TAVOLE GRAFICHE 1 e 2. In the GRAPHIC TABLE 3 the entire component is represented, both in the fixed and in the height-adjustable configuration, with the three parts assembled according to a front view which obviously is substantially the same for the X-Z and Y-Z planes following the symmetry: in the global graph it is possible to view the maximum rotation obtainable from the articulated base, as well as the identification of the various elements that compose it according to the indications given in the upper description specifically highlighted in GRAPHIC TABLES 1 and 2.

Come evidenziato nella Tavola 1, l’intero sistema si presta in modo adeguato all’aumento della superficie della piastra di appoggio al suolo mediante l'inserimento di una ulteriore elemento opzionale (non necessario per il funzionamento della basetta snodabile prima descritta) definito contro-piastra di base ‘D’ in acciaio di spessore e dimensioni superiori alla piastra A3 del basamento ‘A’, e provvista di guattro perni Ό2’ verticali di lunghezza pari ad almeno lo spessore della piastra ‘A3’, disposti coassialmente delle forature ‘A4’ della piastra ‘A3’ del basamento snodabile ‘A’ che, inseriti nelle citate forature, rendono l’intero componente un unico pezzo solidale; anche tale ulteriore contro-piastra è provvista delle forature ‘D3’ in prossimità dei guattro vertici, necessarie per l’ancoraggio al piano di appoggio, mediante massellatura. Per la stabilità di un intero sistema rigido che si intende poggiare sul piano inclinato mediante l’uso delle predette basette regolabili poste alla base, è indispensabile che l’intero sistema rigido sia provvisto di almeno tre basette regolabili di appoggio non allineate ed adeguatamente dislocate, che eventualmente possono essere bloccate al piano di appoggi^ per contrastare gli scivolamenti. As shown in Table 1, the entire system is suitable for increasing the surface of the support plate on the ground by inserting an additional optional element (not necessary for the operation of the jointed base described above) defined as counter- steel base plate 'D' with a thickness and dimensions greater than the plate A3 of the base 'A', and equipped with four vertical pins Ό2 'with a length equal to at least the thickness of the plate' A3 ', arranged coaxially with the holes' A4' of the plate 'A3' of the articulated base 'A' which, inserted in the aforementioned holes, make the entire component a single integral piece; also this additional counter-plate is provided with the 'D3' holes in the vicinity of the four vertices, necessary for anchoring to the support surface, by means of blocking. For the stability of an entire rigid system that is intended to rest on the inclined plane through the use of the aforementioned adjustable bases placed at the base, it is essential that the entire rigid system is equipped with at least three adjustable support bases that are not aligned and adequately displaced, which, if necessary, can be locked to the support surface to prevent slipping.

Claims

CLAIMS OF THE UTILITY MODEL WITH THE TITLE "FIXED OR HEIGHT ADJUSTABLE ARTICULATED BASE AND REMOVABLE" 1. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that it has been specifically studied and designed to create a system that allows it to rest on an X-Y plane even when it has an inclination in both X and Y direction also contemporary, keeping perfectly vertical the element of the structure, equipment or machine on which the load to be transferred to the support surface acts; this claim is made explicit in GRAPHIC TABLE 3 where it is evident that the revolving base 'A' of the invention rests on a strongly inclined plane, while the flat element 'B.a2' or 'B.b2' of the vertical support 'B.a' or 'B.b' maintains the horizontality of the upper plane and the consequent verticality of the element 'B.a3' or 'B.b3' connecting with the rod or the element on which acts the action to be transferred to the support surface; the rotation occurs around the geometric centers of the element 'B.a1' or 'B.b1' of the vertical support and of the seat '1' of the swivel base which are practically coincident; the support thus created transfers the vertical action to the support surface in a rational and functional way.

2. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that although the swivel base 'A' and the vertical support 'B.a' or 'B-b' can perform the required rotations, the two distinct parts cannot detach due to the presence of the specially shaped block element 'C', as it is screwed to the swivel base 'A' by means of 4 screws placed in the seats' C2 'of the block plate and anchored in the threaded seats A5' of the rise of the articulated base 'A'; the presence of captive truncated conical head fixing screws within the block plate 'C', allows the further claim referred to in point 8 above.

3. With reference to claim no. 1 and 2, if the support surface has a slope greater than 5-8% to avoid slipping phenomena, it is possible to lock the swivel base 'A' to the support surface by means of special plugs to be inserted in the holes A3 'specially prepared in the swivel base of the articulated base and anchored to the support surface;

4. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that although the three components can be dismantled, once the assembly is complete, the final element obtained is made up of a single articulated element and cannot be separated unless the intervention of the operator, a circumstance that can be seen in TABLE 3;

5. For the fixed or height-adjustable articulated base, the easy modularity of its three steel components is claimed, as clearly evident in TABLE 1 which distinguishes Articulated base A ', Fixed vertical support' B.a 'or' B. b 'height adjustable and' C 'lock plate; this particular peculiarity allows easy maintenance and immediate interchangeability of the component that should deform;

6. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that for its operation no form of lubrication is necessary as the frictional parts such as the element 'B.a1' or 'B. b1 'of the vertical support and element A1 of the revolving base, if necessary and in the presence of significant actions, can be made with special high-strength steels. In particular, the element has been designed for singular positioning or without the need for continuous or repeated adjustments, so that the correct position has been identified (TV swivel base coplanar with the support surface and element 'B.a2' or 'B.b2' of the vertical horizontal support) you can proceed with the assembly of the upper part to be kept vertical, making any adjustment adjustments using a level and hammer;

7. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that the articulation of the base is possible in any inclination following the coincidence of the rotation centers of the element 'B.a1' or 'B.b1' of the vertical support with the seat A1 of the revolving support A '; in fact, the radii of curvature of the two elements must be such that a small air blade of a few tenths of a millimeter remains between them, which allows the base to rotate even with the block plate 'C' tightened to the articulated base 'A';

8. For the fixed or height adjustable articulated base, made entirely of steel, it is claimed that the articulation of the TV base allows to reach the maximum inclination foreseen for all directions as the element 'B.a2' or 'B. b2 'of the vertical support has a truncated conical shape; the lower surface of this element is inclined by an angle of 27 ° equivalent to that of the maximum rotation of the articulated base: the perfect planarity of this surface with that of the extrados of the block plate 'C' allows to reach the maximum rotations foreseen in all possible directions (from 0 to 360 degrees in the X-Y plane);

9. For the fixed or height-adjustable articulated base, made entirely of steel, the possibility of multiple uses and / or uses is claimed as on the upper part of the element 'B.a2' or 'B.b2' of the vertical support is It is possible to place the connecting element with the structure to be kept vertical. In particular, in the case of use in typical metal scaffolding for construction or maintenance of any type, a 'fixed articulated base' can be obtained if the connection element welded to the specific upper surface of the vertical support element is made with a smooth tube in 'B.a3' steel to be inserted coaxially at the base of the tubular upright of the scaffolding, while the "height-adjustable articulated base" is obtained by welding a specific 'B.b3 steel threaded tube to the upper surface of the vertical support element. '' equipped with threaded ring 'B.b4' for height adjustment: in this case it is possible to coaxially insert the base of the tubular upright of the scaffolding into the threaded tube 'B.b3' until the upright hits the threaded ring ' B.b4 ', necessary for height adjustment by rotating it;

10. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that the vertical action at the base of the vertical element is transferred to the support surface through direct contact between the vertical element and element 'B.a2' of the vertical support 'B.a' in the case of a fixed articulated base or of the threaded ring nut 'B.b4' placed in the element 'B.b3' bound to the vertical support, in the case of a height-adjustable articulated base; subsequently, for both types, in cascade by means of the elements' B.a2 'or' B.b2 ',' B.a1 'or' B.b1, Ά1 ', Ά2' 'A3', the action is transferred the support surface;

11. For the fixed or height-adjustable articulated base, made entirely of steel, its ability to carry even heavy loads is claimed, depending on the size and resistant sections that are assigned to it based on the outcome of the static tests;

12. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that the entire system may have an additional accessory component (not necessary for the operation of the articulated base) called "counter-base plate" 'D '' in steel with a square shape suitable for increasing the contact surface with the ground having an adequate thickness and side, provided with four vertical pins' D2 'having a length at least equal to the thickness of the plate Ά3', arranged in correspondence with the holes' A4 ' of the plate 'A3' of the articulated base 'A': these pins Ό2 'are necessary to couple the aforementioned supplementary plate with the adjustable base A3' of the articulated base 'A' in order to avoid slipping, a circumstance that is obtained by inserting of the aforementioned four pins (possibly also threaded for subsequent locking to the base with suitable nuts) inside the four holes 'A4' present in the plate 'A3' of the base articulated arm Ά ’; also this additional base counter-plate must be provided with the four holes 'D3' near the four vertices, necessary for anchoring to the support surface, using suitable chemical or mechanical plugs;

13. For the fixed or height-adjustable articulated base, made entirely of steel, it is claimed that the entire system actually creates a spherical hinge that transfers to the ground only normal stress centered in the case of support on a horizontal plane, while in the case of support on an inclined plane in addition to the normal centered effort, a shear action tangent to the support plane is generated, which must be counteracted by the anchors that block the entire system to the ground: in no case are bending moments transferred to the support plane .
