Description
Appareil destiné à servir de signal acoustique pour véhicules. L'objet de l'invention est un appareil des tiné à servir de signal acoustique pour véhi cules, caractérisé par la combinaison d'un sif flet avec une pompe à air actionné par la rotation d'une roue du véhicule.
Le dessin ci-joint montre une forme d'exé cution de l'invention, donnée à titre d'exemple. Fig. 1 est une vue de face de l'appareil; Fig. 2 est une vue dudit de gauche à droite de la fig. 1.
Dans la forme d'exécution représentée, l'appareil comporte un cylindre a de pompe à air oscillant sur un pivot b, porté par un supporte, fixé à l'aide d'une bride d à la fourche d'un vélo. Le supporte porte, en outre, un arbre e, dont l'une des extrémités porte un plateau à manivelle f actionnant la tige de piston g de la pompe à air. L'au tre extrémité de l'arbre e porte un galet d'en traînement h destiné à être mis en contact avec la roue du vélo lorsque l'on veut faire résonner le sifflet.
La bride d est reliée à la partie cl du sup port c à l'aide d'un ressort, non visible au dessin, qui tend à maintenir le galet h écarté de la roue du vélo. Le bras cl est pourvu d'une chaînette îfz ou d'un autre moyen d'ac- tionnement quelconque, placé à portée du cycliste et permettant de le relever tempo rairement dans le sens de la flèche pour pro duire l'entraînement du galet 7t par la roue.
Dès que cet entraînement se produit, la manivelle f produit à son tour le fonctionne ment du piston g de la pompe a.
Cette dernière porte un sifflet i avec dis positif de réglage k, destiné à régler à vo lonté le son du sifflet.
Device intended to serve as an acoustic signal for vehicles. The object of the invention is an apparatus designed to serve as an acoustic signal for vehicles, characterized by the combination of a sif flet with an air pump actuated by the rotation of a wheel of the vehicle.
The accompanying drawing shows one embodiment of the invention, given by way of example. Fig. 1 is a front view of the apparatus; Fig. 2 is a view of said from left to right of FIG. 1.
In the embodiment shown, the apparatus comprises an air pump cylinder a oscillating on a pivot b, carried by a support, fixed by means of a flange d to the fork of a bicycle. The support also carries a shaft e, one end of which carries a crank plate f actuating the piston rod g of the air pump. The other end of the shaft e carries a drag roller h intended to be brought into contact with the wheel of the bicycle when the whistle is to be sounded.
The flange d is connected to the part cl of the support c by means of a spring, not visible in the drawing, which tends to keep the roller h away from the wheel of the bicycle. The arm cl is provided with a chain îfz or any other means of actuation, placed within reach of the cyclist and enabling him to be temporarily raised in the direction of the arrow to produce the drive of the roller 7t by the wheel.
As soon as this drive takes place, the crank f in turn operates the piston g of the pump a.
The latter carries a whistle i with an adjustment device k, intended to adjust the sound of the whistle as desired.
