Description

Descrizione dell'invenzione industriale avente per titolo: Description of the industrial invention entitled:

"MECCANISMO CHE CONSENTE DI TENDERE E MANTENERE IN TENSIONE TELO DI QUALUNQUE FORMA E DIMENSIONE". "MECHANISM THAT ALLOWS TO STRETCH AND MAINTAIN CANVAS OF ANY SHAPE AND SIZE IN TENSION".

RIASSUNTO DEL TROVATO : forma oggetto della presente invenzione un dispositivo meccanico che consente di tendere con faciltà e rapidità un telo e di mantenerlo in tensione fino all'utilizzazione. SUMMARY OF THE INVENTION: the subject of the present invention is a mechanical device which allows a sheet to be stretched easily and quickly and to keep it under tension until use.

Un telo serve teso per diversa applicazioni, in particolare quando si deve rivestire un altro telo lacerato o debole per costituzione, per vetustà o per attacco di agenti deterioranti. In commercio già esistono meccanismi idonei aa non altrettanto agevoli ed eleganti nell'uso come l'oggetto della presente invenzione. A sheet is used stretched for different applications, in particular when it is necessary to cover another sheet that is torn or weak by constitution, by age or by attack of deteriorating agents. On the market there are already suitable mechanisms that are not as easy and elegant in use as the object of the present invention.

Il dispositivo meccanico di cui si tratta è costituito in linea di principio da gomiti e aste ruotanti e bloccabili. The mechanical device in question consists in principle of rotating and lockable elbows and rods.

DESCRIZIONE DELL'INVENZIONE : l'invenzione è illustrata a solo titolo di esempio, non limitativo, nell'annesso disegno, nel quale è rappresentato un dispositivo costituito da gomiti, aste leve per il movimento manuale delle aste e spine per il bloccaggio delle stesse. Non si esclude che il movimento di rotazione delle aste possa essere ottenuto, oltre che con azione manuale come nella fig. a, per -mezzo di comandi idraulici o pneumatici. DESCRIPTION OF THE INVENTION: the invention is illustrated by way of non-limiting example only, in the attached drawing, which shows a device consisting of elbows, lever rods for manual movement of the rods and pins for locking them. It is not excluded that the rotation movement of the rods can be obtained, as well as with manual action as in fig. a, by means of hydraulic or pneumatic controls.

Dette aste possono essere bloccate non solo con spinotti, come nella fig- a, ma anche per mezzo di meccanismi autobloccanti figg. b - c - d. Said rods can be locked not only with pins, as in fig-a, but also by means of self-locking mechanisms figs. b - c - d.

Tutti gli elementi costituenti il dispositivo meccanico, oggetto del brevetto, possono essere di qualunque materiale ed avere qualunque forma e dimensione. All the elements making up the mechanical device, object of the patent, can be of any material and have any shape and size.

Nella fig. a sono previsti quattro gomiti (1) dotati di feritoia (2) dove trova alloggiamento la spina di bloccaggio (3), filettata o non, da inserire in appositi fori (11} praticati nelle aste (4). Nelle aste sono praticati dei fori (5) che permettono l'inserimento della leva (6) con la quale si ottiene la rotazione delle aste stesse. Queste sono dotate di denti (7) ai quali si aggancia il telo da tendere. 1 gomiti sono provvisti anche di piedino (8) per consentire la rotazione libera delle aste. In fig. a there are four elbows (1) equipped with a slot (2) where the locking pin (3), threaded or not, is housed, to be inserted in special holes (11} made in the rods (4). Holes are drilled in the rods (5) which allow the insertion of the lever (6) with which the rotation of the rods is obtained. These are equipped with teeth (7) to which the cloth to be stretched is hooked. 1 elbows are also equipped with a foot (8 ) to allow free rotation of the rods.

Nella fig. b è rappresentato l'attacco tra asta e gomito per mezzo di un cuscinetto (9) autobloccante nella rotazione, permessa solo in un senso. In fig. b shows the connection between the rod and the elbow by means of a bearing (9) which is self-locking in rotation, allowed only in one direction.

Nella fig. c il sistema autobloccante è ottenuto con ruote dentate frontali (10) mentre nella fig. d con ruota d'arresto. In fig. c the self-locking system is obtained with front toothed wheels (10) while in fig. d with stop wheel.

L'uso del meccanismo in questione è molto semplice. Alloggiate le aste nei gomiti, si posizionano i denti (7) normalmente al piano del telaio così ottenuto. Si aggancia il telo ai denti avendo cura di tendere il più possibile il te^o stesso. The use of the mechanism in question is very simple. Once the rods are housed in the elbows, the teeth (7) are positioned normally on the plane of the frame thus obtained. The cloth is attached to the teeth, taking care to stretch yourself as much as possible.

Si inserisce la leva di comando (6) nei fori (5) e si ruotano le aste in modo da tendere il telo. Insert the control lever (6) into the holes (5) and rotate the rods in order to stretch the fabric.
