Description

D ESC R IZ ION E DESCRIPTION

dell'invenzione avente per titolo: of the invention entitled:

" Dispositivo di chiusura a leva per calzature sportive " La presente invenzione concerne un dispositivo di chiusura a leva per calzature sportive. "Lever closure device for sports shoes" The present invention relates to a lever closure device for sports shoes.

Sono noti dispositivi di chiusura a leva per calzature sportive: essi generalmente comprendono un braccio di leva, solidale ad un lembo del tomaio al quale, è articolato un tirante impegnantesi selettivamente con uno dei denti di una rastrelliera vincolata all'altro lembo del tomaio. Lever closure devices for sports shoes are known: they generally comprise a lever arm, integral with a flap of the upper to which a tie-rod is articulated, engaging selectively with one of the teeth of a rack connected to the other flap of the upper.

Tali noti dispositivi presentano tuttavia alcuni inconvenienti ed in particolare: However, these known devices have some drawbacks and in particular:

- la possibile formazione di ghiaccio fra i denti della rastrelliera, - the possible formation of ice between the rack teeth,

- un elevato ingombro longitudinale della rastrelliera per avere un ampio campo di regolazione, - a high longitudinal dimension of the rack to have a wide adjustment range,

- la necessità di utilizzare differenti rastrelliere a seconda della conformazione del tomaio della calzatura. - the need to use different racks according to the conformation of the shoe upper.

Secondo l'invenzione tale scopo è raggiunto con un dispositivo di chiusura a leva per calzature sportive comprendente un braccio di leva articolato ad una basetta vincolata ad un lembo del tomaio e provvista di un tirante impegnabile in un elemento di aggancio vincolato all'altro lembo del tomaio caratterizzato dal fatto che il tirante è costituito da un cavo flessibile inserito in una pluralità di blocchetti liberamente scorrevoli lungo esso e che l'elemento di aggancio è costituito da un elemento a forcella impegnabile selettivamente fra due blocchetti contigui. According to the invention, this object is achieved with a lever closure device for sports shoes comprising a lever arm articulated to a base attached to a flap of the upper and provided with a tie rod that can be engaged in an attachment element bound to the other flap of the upper. upper characterized in that the tie rod is constituted by a flexible cable inserted in a plurality of blocks freely sliding along it and that the coupling element is constituted by a fork element which can be selectively engaged between two contiguous blocks.

La presente invenzione viene qui di seguito ulteriormente chiarita in una sua preferita forma di pratica realizzazione ed in due varianti realizzative riportate a scopo esemplificativo e non limitativo con riferimento alle allegate tavole di disegni, in cui: The present invention is further clarified hereinafter in a preferred embodiment thereof and in two embodiments shown by way of non-limiting example with reference to the attached drawings, in which:

la figura 1 mostra in vista prospettica esplosa un dispositivo di chiusura secondo l'invenzione, Figure 1 shows an exploded perspective view of a closing device according to the invention,

la figura 2 lo mostra in vista laterale, Figure 2 shows it in side view,

la figura 3 lo mostra in pianta, e Figure 3 shows it in plan, and

le figure 4 e 5 mostrano in pianta due varianti realizzative. Figures 4 and 5 show two embodiment variants in plan.

Come si vede dalle figure il dispositivo di chiusura a leva secondo l'invenzione comprende sostanzialmente una basetta 2 conformata a forcella, vincolabile ad un lembo del tomaio della calzatura, fra le cui ali 4 si impegna un perno 6 di articolazione di un braccio di leva 8. As can be seen from the figures, the lever closure device according to the invention substantially comprises a base 2 shaped like a fork, which can be fixed to a flap of the shoe upper, between whose wings 4 engages a pin 6 for the articulation of a lever arm 8.

Il braccio di leva è conformato ad U e fra i suoi rebbi è articolata , in corrispondenza di un rivetto 10, una boccola 12 internamente filettata. The lever arm is U-shaped and an internally threaded bushing 12 is articulated between its prongs at a rivet 10.

Nella boccola s'impegna un tirante costituito da un capocorda filettato 14 che trattiene un cavo flessibile 16 che impegna una molla 18 ed una pluralità di blocchetti troncoconici 20 trattenuti da un pomolo 22. A tie rod is engaged in the bush consisting of a threaded cable lug 14 which holds a flexible cable 16 which engages a spring 18 and a plurality of conical blocks 20 held by a knob 22.

L'invenzione comprende altresì un elemento a forcella 24 vincolato all'altro lembo del tomaio i cui rebbi 26 delimitano un'apertura di larghezza di poco superiore al diametro del cavo flessibile 16. The invention also comprises a fork element 24 constrained to the other edge of the upper, the prongs 26 of which delimit an opening with a width slightly greater than the diameter of the flexible cable 16.

L'impiego del dispositivo di chiusura è quello tradizionale che prevede che, una volta che il braccio di leva è stato ruotato in senso antiorario (per chi osserva fig. 2) il tirante venga impegnato tra i rebbi 26 della forcella 24 e successivamente il braccio di leva 8 venga ruotato in senso orario in modo da provocare, grazie al contrasto effettuato tra il blocchetto a contatto con la forcella, il reciproco accostamento dei lembi del tomaio della calzatura. The use of the closing device is the traditional one which provides that, once the lever arm has been rotated counterclockwise (for those who observe fig. 2), the tie rod is engaged between the tines 26 of the fork 24 and subsequently the arm lever 8 is rotated clockwise so as to cause, thanks to the contrast made between the block in contact with the fork, the mutual approach of the edges of the shoe upper.

Nel caso in cui il grado di ammorsamento non sia quello desiderato analoga manovra viene effettuata impegnando il cavo in una posizione fra due blocchetti differenti. If the degree of clamping is not the desired one, a similar maneuver is carried out by engaging the cable in a position between two different blocks.

Una volta raggiunta la desiderata configurazione è possibile effettuare una microregolazione ruotando il capocorda 14 rispetto alla boccola filettata 12. Once the desired configuration has been reached, a micro-adjustment can be carried out by rotating the cable lug 14 with respect to the threaded bushing 12.

Da quanto detto risulta chiaramente che il dispositivo si presenta particolarmente vantaggioso rispetto ai noti dispositivi ed in particolare: From what has been said it is clear that the device is particularly advantageous with respect to known devices and in particular:

- presenta una maggior facilità di vincolo del tirante in quanto viene eliminata la possibile presenza di ghiaccio fra i denti delle tradizionali rastrelliere, - presents a greater ease of constraint of the tie rod as the possible presence of ice between the teeth of traditional racks is eliminated,

- presenta un ingombro longitudinale ridotto della forcella in quanto il campo di regolazione viene dato dalla lunghezza del cavo flessibile e dal numero dei blocchetti, - has a reduced longitudinal overall dimensions of the fork as the adjustment range is given by the length of the flexible cable and the number of blocks,

- si adatta a qualunque curvatura del tomaio della calzatura grazie alla flessibilità del cavetto, - adapts to any curvature of the shoe upper thanks to the flexibility of the cable,

- consente di effettuare la regolazione micrometrica, a leva allentata, senza disimpegnare il tirante dalla forcella, - allows micrometric adjustment, with the lever loose, without disengaging the tie rod from the fork,

- consente, nel caso di impiego di blocchetti di differente colore, di memorizzare visivamente la posizione di impegno del cavetto fra i due blocchetti e quindi di riposizionarsi in maniera immediata nella stessa configurazione. - it allows, in the case of use of blocks of different colors, to visually memorize the position of engagement of the cable between the two blocks and therefore to reposition itself immediately in the same configuration.

Nella forma di realizzazione illustrata nelle figg. 4 e 5 sono rappresentati due dispositivi di chiusura che utilizzano lo stesso principio inventivo e differiscono soltanto nella forma dei blocchetti che sono rispettivamente sferici (fig. 4) e cilindrici (fig. 5). In the embodiment illustrated in FIGS. 4 and 5 show two closing devices which use the same inventive principle and differ only in the shape of the blocks which are respectively spherical (fig. 4) and cylindrical (fig. 5).

La presente invenzione è stata illustrata e descritta in una sua preferita forma di realizzazione ed in due varianti realizzative ma si intende che altre varianti potranno ad essa in pratica apportarsi senza peraltro uscire dall'aimbito di protezione del presente brevetto per invenzione industriale. The present invention has been illustrated and described in a preferred embodiment thereof and in two embodiment variants but it is understood that other variants may in practice be applied to it without however departing from the scope of protection of the present patent for industrial invention.
