Description

Dispositif de verrouillage pour empecher la rotation d'uue roue. L'invention a, pour objet un dispositif de verrouillage pour empecher la rotation dune roue. Locking device to prevent the rotation of a wheel. The subject of the invention is a locking device for preventing the rotation of a wheel.

Le dessin ei-joint represente, ä titre d'exemple, une forme d'execution de ce dis- positif appliquee ä la roue d'un cycle. The attached drawing shows, by way of example, one form of execution of this device applied to the wheel of a cycle.

La fig: 1 est une vue de face, en coupe longitudinale, 1e verrou etant ferme; La fig. 2 est une vue en rabattement de eöte, correspondant ä la fig. 1 et montrant Je dispositif par bout du cöte de 1'entree dune c16. Le trace en traits interrompus in- dique la Position du verrou ouvert qui est alors vertical et parallele ä la Branche b de la fourche du cycle; Les fig. 3 ä 7 montrent en perspective les elements separes dune serrure. Fig: 1 is a front view, in longitudinal section, the first lock being closed; fig. 2 is a side view, corresponding to FIG. 1 and showing I device by end of side of dune c16 entrance. The trace in broken lines indicates the Position of the open lock which is then vertical and parallel to Branch b of the fork of the cycle; Figs. 3 to 7 show in perspective the separate elements of a lock.

La pike a en forme d'U renverse est fixee sirr la fourche b par colliers c et bou- lons d. L'une des branches de la pike a re- @oit ä son extreniite un pivot e du verrou, ta.ndis que I'autre Branche Porte une gäclie f destinee ä, recevoir et retenir la tete g du- dit verrou. La tige la ä tete g prolonge 1e cylindre i qui contient 1e mecanisme de la serrure. Un ressort ;j attache, dune Part, ä. la pike a et, d'autre pari, au pivot rotatif e solidaire di.i cylindre i tend ä maintenir normalement 1e verrou abaisse, c'est-ä,-dire ä sa Position d'ouvertur e. The pike a in the shape of an inverted U is fixed to the fork b by collars c and bolts d. One of the branches of the pike has received at its end a pivot e of the bolt, while the other Branch carries a trigger f intended to receive and retain the head g of said bolt. The head rod g extends the cylinder i which contains the lock mechanism. A spring ;j attaches, dune Part, ä. the pike a and, on the other hand, to the rotary pivot e integral with the cylinder i tends to normally maintain the first latch lowered, that is to say, to its open position.

Sur cette broche peuvent glisser deux douilles p q de menie longueur, coulissant l'une sur 1'autre en comprimant chacune un ressort ä boudin, respectivement r s d'un diametre correspon- dant au sien propre. Ces douilles sont fen- dues sur toute leer longueur et pareillement dune rainure longitudinale, respectivement p' q' et portent egalement une rainure transversale partant de la Premiere et s'e- tendant sur 1e quart de la circonference, p" q", lesdites rainures longitudinales et transversales ayant une largeur suffisante pour 1e Passage de 1'ergot a. Si les deux rai- nures longitudinales se juxtaposent parfaite- The bolt rod, beyond its bulge k provided with an operating finger l comprises a pin m grooved at the end, at n and provided with a lug o. On this pin can slide two bushings p q of equal length, sliding one over the other, each compressing a coil spring, respectively r s of a diameter corresponding to its own. These casings are split along the entire length and similarly with a longitudinal groove, respectively p' q' and also carry a transverse groove starting from the first and extending over the first quarter of the circumference. , p"q", said longitudinal and transverse grooves having a width sufficient for the first passage of the pin a.

Claims

CLAIM Locking device for preventing the rotation of a wheel, characterized by the combination of a lock rod that is pivoted once on a good support and then rotates on it. - even at 90 degrees to immobilize the wheel between the spokes of which this rod passes, and of a striker which receiving the head of the said rod conforms in such a way that after its free penetration, the said head is retained there when it has turned 90 degrees.
