DISPOSITIVO DI FISSAGGIO AMOVIBILE DI UN'ASTA AD UNA STRUTTURA TUBOLARE REMOVABLE FIXING DEVICE OF A ROD TO A TUBULAR STRUCTURE
DESCRIZIONE DESCRIPTION
Il trovato si riferisce ad un dispositivo di fissaggio amovibile di un'asta ad una struttura tubolare. The invention relates to a removable fixing device of a rod to a tubular structure.
E' noto che gli strumenti denominati trabattelli, usati ad esempio nel campo dell'edilizia per compiere lavori ad una certa altezza, sono dotati di struttura tubolare comprendente due spalle contrapposte, ognuna delle quali à ̈ formata da due montanti collegati mediante traversini-gradini che sono inseriti nei montanti stessi con le sezioni terminali aperte. Le spalle sono poi collegate da aste orizzontali, o traverse, e da aste diagonali, o saette, che presentano alle estremità dispositivi che penetrano nelle dette sezioni aperte così da fissare amovibilmente le dette aste alla struttura per realizzare controventatura ed irrigidimento della struttura stessa. It is known that the tools called scaffolding, used for example in the construction field to carry out work at a certain height, are equipped with a tubular structure comprising two opposing shoulders, each of which is formed by two uprights connected by means of cross-treads-steps which they are inserted into the uprights themselves with the end sections open. The abutments are then connected by horizontal rods, or crosspieces, and by diagonal rods, or lightning bolts, which have devices at the ends which penetrate the open sections so as to removably fix the rods to the structure to create bracing and stiffening of the structure itself.
Ovviamente il caso citato dei trabattelli non à ̈ l'unico in cui si presenta la necessità di fissare amovibilmente un'asta ad una struttura tubolare, operando su dispositivi presenti alle estremità dell'asta stessa, inseriti nell'ambito dei tubi costituenti la struttura. Obviously, the cited case of scaffolding is not the only one in which the need arises to fix removably a rod to a tubular structure, operating on devices present at the ends of the rod itself, inserted within the tubes making up the structure.
E' chiaro che questi dispositivi debbono essere inseribili nei tubi della struttura con grande facilità ed essere bloccati amovibilmente nei detti tubi con altrettanta facilità a seguito di una semplice manovra da parte dell'operatore addetto, e questo, in assenza nella tecnica nota di dispositivi che assicurino queste caratteristiche, si rivela essere il compito del presente trovato. It is clear that these devices must be inserted into the pipes of the structure with great ease and be removably locked in said pipes with equal ease following a simple maneuver by the operator in charge, and this, in the absence in the known art of devices that ensure these characteristics, it turns out to be the aim of the present invention.
Il compito proposto viene raggiunto da un dispositivo di fissaggio amovibile di un'asta ad una struttura tubolare, secondo il trovato, caratterizzato dal fatto di comprendere le caratteristiche di cui alle rivendicazioni seguenti. The proposed aim is achieved by a removable fixing device of a rod to a tubular structure, according to the invention, characterized in that it comprises the characteristics of the following claims.
Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita ma non esclusiva del trovato, illustrata a titolo indicativo e non limitativo negli uniti disegni in cui: Further characteristics and advantages will become clearer from the description of a preferred but not exclusive embodiment of the invention, illustrated by way of non-limiting example in the accompanying drawings in which:
la figura 1 rappresenta un trabattello con evidenziata un'asta dotata del dispositivo secondo il trovato; Figure 1 is a view of a scaffolding showing a rod equipped with the device according to the invention;
le figure 2 e 3 mostrano rispettivamente il dispositivo secondo il trovato con inserto in materiale elastico tipo gomma indeformato e deformato; Figures 2 and 3 respectively show the device according to the invention with an insert made of an elastic material such as undeformed and deformed rubber;
la figura 4 mostra il trovato in vista esplosa; la figura 5 mostra un volantino; Figure 4 shows the invention in an exploded view; figure 5 shows a leaflet;
la figura 6 mostra una vista da sopra del corpo del dispositivo; figure 6 shows a top view of the body of the device;
la figura 7 mostra la sezione con il piano VII-VII di figura 6. figure 7 shows the section with plane VII-VII of figure 6.
Con riferimento alle suddette figure, à ̈ indicato con 1 il trabattello che comprende, tra le altre, l'asta 2 dotata alle estremità dei due dispositivi secondo il trovato 3 e 4 che sono inseriti nei tubi 5 e 6 della struttura del trabattello per il fissaggio amovibile dell'asta stessa. With reference to the aforementioned figures, 1 indicates the scaffolding which includes, among others, the rod 2 provided at the ends of the two devices according to the invention 3 and 4 which are inserted in the tubes 5 and 6 of the scaffolding structure for removable fixing of the rod itself.
Più precisamente i detti dispositivi 3 e 4 sono inseriti nelle estremità aperte che i tubi 5 e 6 presentano, del tipo ad esempio visibile per il tubo 7, indicata con 8. I due dispositivi 3 e 4 sono identici, e nel seguito descriveremo il dispositivo 3. More precisely, said devices 3 and 4 are inserted in the open ends that tubes 5 and 6 have, of the type visible for example for tube 7, indicated with 8. The two devices 3 and 4 are identical, and we will describe the device below. 3.
Il detto dispositivo comprende il corpo cilindrico 9 con base 9a dotato dell'appendice 10 con dentelli che si deriva dal corpo stesso con direzione perpendicolare all'asse, ed à ̈ atta ad essere inserita nell'estremità dell'asta 2 per essere ivi bloccata. Said device comprises the cylindrical body 9 with base 9a equipped with the appendix 10 with teeth which derives from the body itself with a direction perpendicular to the axis, and is able to be inserted in the end of the rod 2 to be locked therein.
Il corpo cilindrico 9 à ̈ dotato di una cavità cilindrica 11 delimitata in corrispondenza della base da due piste elicoidali consecutive 12 e 13 delimitate da denti 14 e 15, le quali piste presentano i tratti finali in salita rispettivamente 12a e 13a in contropendenza; à ̈ poi indicato con 16 un foro passante che attraversa in corrispondenza dell'asse la base 9a del detto corpo 9. The cylindrical body 9 is equipped with a cylindrical cavity 11 delimited at the base by two consecutive helical tracks 12 and 13 delimited by teeth 14 and 15, which tracks have the final uphill sections 12a and 13a respectively in counter-slope; 16 indicates a through hole which crosses the base 9a of said body 9 at the axis.
Il dispositivo 3 comprende anche un volantino 17 inserito nella cavità cilindrica 11 del corpo 9, dotato di vite 18 fuoruscente dal corpo stesso in corrispondenza del foro 16 e coniugata all'estremità filettata 18a con un dado di riscontro 19 che delimita con una rondella 20 una porzione di spazio adiacente la base 9a del corpo 9 occupata da un inserto 21 in materiale elastico tipo gomma attraversato dalla vite 18 e atto ad essere inserito nel tubo 5 della struttura del trabattello 1. The device 3 also comprises a handwheel 17 inserted in the cylindrical cavity 11 of the body 9, equipped with a screw 18 protruding from the body itself in correspondence with the hole 16 and mated to the threaded end 18a with a stop nut 19 which delimits with a washer 20 a portion of space adjacent to the base 9a of the body 9 occupied by an insert 21 made of elastic rubber-like material crossed by the screw 18 and able to be inserted into the tube 5 of the scaffolding structure 1.
Il detto volantino 17 à ̈ dotato delle due protuberanze 22 e 23 atte a prendere contatto rispettivamente con le piste 12 e 13, e così esso risulta mobile, a seguito di semplice rotazione impartita dall'operatore, tra una prima posizione in cui le protuberanze 22, 23 sono rispettivamente a contatto con l'estremità iniziale delle piste elicoidali 12 e 13 addossate ai dentelli 14 e 15, e conseguentemente il volantino 17 à ̈ in condizione di massimo inserimento nella cavità 11 con l'inserto 21 nella condizione indeformata visibile nella figura 2, disponibile ad essere inserito e disinserito nel tubo 5 del trabattello, ed una seconda posizione in cui le protuberanze 22, 23 sono giunte a contatto rispettivamente con i tratti finali in salita in contropendenza 12a, 13a delle piste elicoidali per rimanere ivi bloccate fino ad una nuova rotazione del volantino 17 in senso opposto, e conseguentemente il volantino stesso à ̈ in condizione di massima estrazione dalla cavità 11 con l'inserto 21 deformato come visibile nella figura 3, stretto tra la rondella 20 spinta dal dado 19 e la base 9a del corpo 9, e dunque bloccato nel tubo 5 della struttura del trabattello. Said handwheel 17 is equipped with the two protuberances 22 and 23 adapted to make contact respectively with the tracks 12 and 13, and thus it is mobile, following a simple rotation imparted by the operator, between a first position in which the protuberances 22, 23 are respectively in contact with the initial end of the helical tracks 12 and 13 leaning against the teeth 14 and 15, and consequently the handwheel 17 is in a condition of maximum insertion in the cavity 11 with the insert 21 in the undeformed condition visible in the figure 2, available to be inserted and disconnected in the tube 5 of the scaffolding, and a second position in which the protuberances 22, 23 have come into contact respectively with the final uphill sections in counter-slope 12a, 13a of the helical tracks to remain blocked there until to a new rotation of the handwheel 17 in the opposite direction, and consequently the handwheel itself is in a condition of maximum extraction from the cavity 11 with the insert 21 deformed as visible in Figure 3, sandwiched between the washer 20 pushed by the nut 19 and the base 9a of the body 9, and therefore blocked in the tube 5 of the scaffolding structure.
Se si pone mente al fatto che l'asta 2 à ̈ dotata ad una estremità del dispositivo 3 che si à ̈ descritto ed all'altra estremità del dispositivo 4 identico, subito si comprende come il trovato sia in grado di realizzare il bloccaggio amovibile dell'asta stessa sul trabattello con mezzi di grande semplicità sia costruttiva che funzionale. If one thinks of the fact that the rod 2 is equipped at one end with the device 3 described above and at the other end with the identical device 4, it is immediately clear how the invention is able to provide the removable locking of the rod itself on the scaffolding with means of great constructive and functional simplicity.
Il trovato descritto à ̈ suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo: così ad esempio al posto delle due piste elicoidali che stanno alla base della cavità 11 potrà essere presente una sola pista ovvero un numero di piste superiore a due, e conseguentemente il volantino 17 sarà dotato di tante protuberanze quante sono le piste elicoidali presenti, atte ciascuna a prendere contatto con una pista. The described invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept: thus for example, instead of the two helical tracks which are at the base of the cavity 11, only one track or a higher number of tracks may be present to two, and consequently the handwheel 17 will be equipped with as many protuberances as there are helical tracks present, each suitable for making contact with a track.
