DESCRIZIONE DELLA LEVA A BILANCIERE APRITOMBINI DESCRIPTION OF THE OPENING ROCKER LEVER
DESCRIZIONE TECNICA: La leva a bilanciere apritombini è composta da un braccio primario, un fulcro e un braccio secondario oscillante che termina con un sistema di gancio-staffa. TECHNICAL DESCRIPTION: The barrel opener rocker lever is composed of a primary arm, a fulcrum and a secondary oscillating arm that ends with a hook-bracket system.
Il braccio primario è costituito da una staffa di ferro piatto, dalle misure di circa cm. 105 di lunghezza, cm. 3,5 di larghezza e cm. 0,8 di spessore. Esso risulta rettilineo nel tratto che funge da manico o da impugnatura, leggermente incurvato in corrispondenza del fulcro e di nuovo rettilineo all'estremità in corrispondenza del braccio secondario oscillante {ved. disegno in tav.). Nella riversione ripiegabile - ved. disegno in tavola II - il braccio primario risulta snodato circa alla metà della sua sezione rettilinea ed è dotato di una cerniera realizzata mediante un perno ed un battente, che garantisce la rigidità dei due semibracci dispiegati iper l'uso, i quali sopportano la forza attiva che viene esercitata sull'impugnatura. The primary arm consists of a flat iron bracket, measuring approximately cm. 105 in length, cm. 3,5 of width and cm. 0.8 thick. It is rectilinear in the portion that acts as a handle or grip, slightly curved at the fulcrum and again rectilinear at the end in correspondence with the oscillating secondary arm {see drawing in table). In the foldable reversion - see drawing in table II - the primary arm is articulated at about half of its rectilinear section and is equipped with a hinge made by means of a pin and a sash, which guarantees the rigidity of the two half-arms deployed for use, which bear the active force which is exerted on the handle.
Il fulcro è realizzato con un tondino d'acciaio 012 ripiega to a forma di U, saldato alle estremità della parte convessa ideila curvatura del braccio primario (ved. disegno in (tav.); al fulcro, cosi realizzato, si accompagna anche luna piastrina di ferro dentata (di circa millimetri 2,5 di spessore) saldato in modo da realizzare un appoggio ruvido. The fulcrum is made with a U-shaped 012 steel rod, welded to the ends of the convex part of the curvature of the primary arm (see drawing in (table); the fulcrum, thus made, is also accompanied by a plate of toothed iron (about 2.5 mm thick) welded in order to create a rough support.
Il braccio secondario oscillante è situato all’estremità opposta dell'impugnatura ed è collegato al braccio primario mediante un foro ed un perno,realizzanti il vincolo di cerniera cilindrica che permette l'oscillazione; esso termina con il sistema gancio-staffa (realizzato come nel disegno in tav.), il quale consente di effettuare l'aggancio e il movimento roto-traslatorio del coperchio del tombino, nonché la presa sul bordo e il relativo trascinamento dello stesso, una volta estratto. The secondary oscillating arm is located at the opposite end of the handle and is connected to the primary arm by means of a hole and a pin, creating the cylindrical hinge constraint that allows oscillation; it ends with the hook-bracket system (made as in the drawing in the table), which allows to carry out the coupling and the roto-translational movement of the manhole cover, as well as the grip on the edge and the relative dragging of the same, a once extracted.
La leva a bilanciere in questione è adatta all'apertura di tutti i tombini messi a filo del pavimento; sia che abbiano i coperchi con i punti di aggancio in prossimità dei bordi, sia - previo allungamento della staffa tra il fulcro -e il sistema braccio secondario oscillante (gancio-staffa) - che abbiano invece i punti d'aggancio in posizione centrale. The rocker lever in question is suitable for opening all manholes placed flush with the floor; whether they have the covers with the hooking points near the edges, or - after lengthening the bracket between the fulcrum - and the secondary oscillating arm system (hook-bracket) - that they have the hooking points in a central position.
II gancio risulta idoneo ad inserirsi nei tipi più diffusi di fori o feritoie _e punti_d_'aggancio, non esclusi quelli di forme non compatibili, in quanto può essere provvisto di protesi adatte al gancio stesso, che nella parte terminale saranno conformabili alle diverse forme di punti di aggancioa The hook is suitable for insertion into the most common types of holes or slots _and points_ of hooking, not excluding those of incompatible shapes, as it can be provided with prostheses suitable for the hook itself, which in the terminal part will be conformable to the different shapes of points of coupling
USO: La leva a bilanciere va posizionata vicino al tombino da aprire, in prossimità di uno degli appositi punti USE: The rocker lever must be positioned near the manhole to be opened, near one of the appropriate points
di _ aggi del coperchio, dove il gancio va inserito in maniera da_ far presa, affiche,_ aiutandosi con il_ piede sulla staffa, si ottenga _la posizione ottimale per il fulcro; quindi agendo sull'impugnatura, si ottiene un ondeggiamento del bilanciere che solleverà il coperchio dal_ proprio alloRpiamento, consentendone la fuoriuscita e il relativo appoggio sul pavimento o sul proprio telaio; infine, togliendo il gancio dal punto di presa e distendendo completamente il braccio secondario, sarà possibile trascinare il coperchio di lato agganciandolo dal bordo e completare cosi l'operazione di apertura del tombino. Effettuando quest'ultima operazione in senso inverso sarà possibile richiudere il tonbino. of the lid, where the hook is inserted in such a way as to grip, so that, with the help of the foot on the bracket, the optimal position for the fulcrum is obtained; then by acting on the handle, a swaying of the rocker is obtained which will lift the lid from its own position, allowing it to come out and rest it on the floor or on its frame; finally, by removing the hook from the gripping point and completely extending the secondary arm, it will be possible to drag the cover to the side hooking it from the edge and thus complete the operation of opening the manhole. By carrying out this last operation in reverse it will be possible to close the tonbino.
UTILITÀ': Se si considera che attualmente l'apertura dei tombini viene fatta manualmente, o comunque mediante ganci collegati a staffe corte, tirando verso l'alto in posizione curva, sollevando da terra pesi che raggiungono anche 80 - 100 kg., ed effettuando, sempre rimanendo nella stessa posizionerà rimozione laterale del coperchio che consente l'apertura completa del pozzetto, ben si comprendono l'eccessiva fatica, i pericolosi sforzi con ripercussioni sui reni e sulla colonna vertebrale, oltre al rischio di traumi e strappi muscolari, cui gli operatori sono esposti UTILITY: If we consider that the manholes are currently opened manually, or in any case by means of hooks connected to short brackets, by pulling upwards in a curved position, lifting weights from the ground up to 80 - 100 kg., And carrying out , always remaining in the same position, will position the lateral removal of the lid that allows the complete opening of the well, it is well understood the excessive fatigue, the dangerous efforts with repercussions on the kidneys and the spine, in addition to the risk of trauma and muscle tears, which operators are exposed
Questa leva a bilanciere, sfruttando il movimento ondeggiante nella fase di sollevamento, e la lunghezza del braccio principale, in quella di trascinamento, rende l'intera posizione poco faticosa; inoltre, consentendo una posizione eretta ed evitando il sollevamento da terra di pesi elevati, rende più agevole ogni manovra eliminando gli inconvenienti di cui sopra. This rocker lever, exploiting the swaying movement in the lifting phase, and the length of the main arm, in the dragging phase, makes the whole position less tiring; furthermore, allowing an upright position and avoiding the lifting of heavy weights from the ground, it makes every maneuver easier, eliminating the above drawbacks.
SICUREZZA: Infine, tenendo presente che d'inverno le gelate rendono molto difficile con gli attuali metodi, l'apertua dei tombini ghiacciati, e che negli impianti di deposito e rifornimento di carburanti gli operatori per aiutarsi,battono imprudentemente,con staffe metalliche di tipo corto sui coperchi dei tombini, per rompere il ghiaccio, con il rischio di provocare scintille a pochi centimetri dai serbatoi di carburante, compremettendo così la sicurezza loro, di terzi e degli impianti; risulta quanto mai opportuno introdurre in questo settore, l'uso di questa leva a bilanciere che, sfruttando un colpo a scatto che si può imprimere con le braccia sul manico, consente, con il contraccopolto conseguenziale, al braccio secondario snodabile dotato di sistema gancio-staffa, la rottura del ghiaccio circostante al tombino e la facile estrazione del coperchio. SAFETY: Finally, bearing in mind that in winter the frosts make it very difficult with current methods, the opening of frozen manholes, and that in the fuel storage and refueling plants the operators to help themselves, beat imprudently, with metal brackets of the type short on manhole covers, to break the ice, with the risk of causing sparks a few centimeters from the fuel tanks, thus compromising the safety of them, of third parties and of the plants; it is more than ever appropriate to introduce in this sector, the use of this rocker lever which, by exploiting a snap shot that can be impressed with the arms on the handle, allows, with the consequential counter-fold, to the articulated secondary arm equipped with a hook-and-loop system. bracket, the breaking of the ice surrounding the manhole and the easy removal of the lid.
Senza contare che la sua adozione comporterebbe l'eliminazione delle staffe metalliche di tipo corto attualmente in dotazione, il cui uso comporta i pericoli e gli inconve¬ Not to mention that its adoption would involve the elimination of the short type metal brackets currently supplied, the use of which involves the dangers and inconveniences.
