Abstract
Dispositif enrouleur et dérouleur de câble électrique. Pour enrouler et dérouler les câbles de raccordement d'un appareil électrique, on prévoit un tambour (1), monté en rotation sur un rail de guidage (2). A l'intérieur du tambour (1) se trouve un ressort spiral (13). Sur un des côtés du tambour (1) se trouve un étrier (4) destiné au guidage du câble arrivant. Sur l'autre côté du tambour se trouvent trois rouleaux (7, 9, 11), qui assurent le guidage du câble (18). Le ressort spiral (13), à l'intérieur du tambour (1), rétracte le tronçon de câble qui s'étend vers l'appareil. Application notamment aux tondeuses électriques pour gazon.Electric cable rewinder and unwinder device. To wind up and unwind the connection cables of an electrical device, a drum (1) is provided, mounted in rotation on a guide rail (2). Inside the drum (1) there is a spiral spring (13). On one side of the drum (1) there is a bracket (4) for guiding the incoming cable. On the other side of the drum there are three rollers (7, 9, 11), which guide the cable (18). The spiral spring (13), inside the drum (1), retracts the section of cable which extends towards the device. Application in particular to electric lawn mowers.

Ce but est atteint par un dispositif du type ci- This goal is achieved by a device of the type

Comme le tambour ne doit pas recevoir la totalité de la longueur du câble, mais seulement une boucle de ce dernier, le tambour peut être construit d'une manière relativement étroite et légère et peut être utilisé sans bagues collectrices. Comme la partie du câble allant du Since the drum should not receive the entire length of the cable, but only a loop of the cable, the drum can be constructed in a relatively narrow and light manner and can be used without slip rings. As the part of the cable going from

L'invention sera mieux comprise en regard de l'exemple ci-après et du dessin, dans lequel: La Figure 1 est une vue latérale du dispositif S selon l'invention, The invention will be better understood with reference to the example below and the drawing, in which: FIG. 1 is a side view of the device S according to the invention,
La Figure 2 est une vue de dessus de ce dispositif. Figure 2 is a top view of this device.
Un tambour 1 est logé, de façon à pouvoir tourner, A drum 1 is housed, so as to be able to turn,

tant sous la forme d'un rail de soutènement 2 légèrement incurvé. Sur ce rail de soutènement 2 se trouve, sur l'un des côtés du tambour, un organe de guidage, en particulier une fourche 4, destiné au brin arrivant du cable. A la place d'une fourche 4, on pourrait aussi prévoir un oeillet ou analogue, pour assurer le guidage du câble 18 amené au tambour 1. Sur le côté opposé du tambour, trois rouleaux 7, 9, 11 tournent sur trois axes 8, 5,12qui dépassent du rail de soutènement 2, sont parallèles les uns aux autres et à l'axe du tambour 6, both in the form of a slightly curved retaining rail 2. On this retaining rail 2 is on one side of the drum, a guide member, in particular a fork 4, for the strand arriving from the cable. Instead of a fork 4, it would also be possible to provide an eyelet or the like, for guiding the cable 18 fed to the drum 1. On the opposite side of the drum, three rollers 7, 9, 11 rotate on three axes 8, 5, 12 which protrude from the retaining rail 2, are parallel to each other and to the axis of the drum 6,
et peuvent tourner indépendamment les uns des autres. and can rotate independently of each other.
Le rouleau relativement petit, qui s'appuie sur l'axe 8 et se trouve le plus près de la périphérie du tambour, est conçu comme un rouleau de guidage 7 du The relatively small roller, which rests on the axis 8 and is closest to the periphery of the drum, is designed as a guide roller 7 of the

Le câble est placé de la manière ci-après sur le tambour 4 et les rouleaux 7, 9, 11. Tout d'abord, le câble 18, amené au tambour 1, est inséré dans la fourche 4 puis est placé au-dessus du tambour 1 de façon que le câble s'appuie sur la surface d'enroulement cylindrique The cable is placed in the following manner on the drum 4 and the rollers 7, 9, 11. First, the cable 18, fed to the drum 1, is inserted into the fork 4 and is placed above the drum. drum 1 so that the cable rests on the cylindrical winding surface

Then the cable is looped, on the outside, on the neighboring guide roller 7, then

On fait ensuite passer le câble 18 en-dessous du premier rouleau de renvoi 9 et par-dessus le deuxième rouleau de renvoi 11. L'extrémité de câble sortante est ensuite reliée à l'appareil électrique, par exemple une tondeuse. Si maintenant on tire l'extrémité de câble sortante, le ressort 13 se tend et, quand on relâche la traction, le câble 18 se rétracte. Bien évidemment, il The cable 18 is then passed under the first deflection roller 9 and over the second deflection roller 11. The outgoing cable end is then connected to the electrical apparatus, for example a lawn mower. If now pulling the outgoing cable end, the spring 13 is stretched and, when the traction is released, the cable 18 retracts. Of course, he
