Description

Dispositif élévateur-roulant pour lave-linge ou autre machine analogue LaRoll-lift device for washing machine or other similar machine La

présente invention concerne un dispositif destiné k être placé sous un lave-linge afin de faciliter, chaque fois que cela est nécessaire, le déplacement de ce dernier par roulement; pour ce faire, ce dispositif est équipé de roulettes k essieux fixes et d'un mécanisme permettant de relever les roulettes, leur contact avec le sol étant ainsi the present invention relates to a device intended to be placed under a washing machine in order to facilitate, whenever necessary, the movement of the latter by rolling; to do this, this device is equipped with castors k fixed axles and a mechanism for raising the casters, their contact with the ground being thus

évité lorsque la machine est immobilisée à son poste de travail. avoided when the machine is immobilized at its work station.

Le passage d'une position à l'autre est obtenu par actionnement du mécanisme précité à l'aide d'un levier latéral qui, en position de repos, c'est-à-dire lorsque les roulettes sont relevées et ne touchent pas le sol, reste appliqué contre la partie inférieure de la machine, en étant pratiquement invisible. Ce dispositif peut, naturellement, être utilisé pour d'autres appareils électroménagers de volume et de poids importants. On va maintenant décrire la présente invention en se référant aux dessins annexés sur lesquels: la figure t est une élévation-coupe longitudinale du nouveau dispositif avec les roulettes en position haute; la figure 2 montre ce mime dispositif avec les roues au sol; la figure 3 est une vue en plan avec indication du plan de coupe longitudinal I-I par lequel est représentée la figure t; Les figures 4 et 5 sont des coupes transversales The passage from one position to the other is obtained by actuation of the aforementioned mechanism using a lateral lever which, in the rest position, that is to say when the rollers are raised and do not touch the ground, remains applied against the lower part of the machine, being practically invisible. This device can, of course, be used for other household appliances of large volume and weight. We will now describe the present invention with reference to the accompanying drawings in which: Figure t is a longitudinal sectional elevation of the new device with the rollers in the high position; Figure 2 shows this mime device with the wheels on the ground; Figure 3 is a plan view with indication of the longitudinal section plane I-I which is shown in Figure t; Figures 4 and 5 are cross sections

correspondant respectivement aux plans de coupe IV-IV et V-V. corresponding respectively to section planes IV-IV and V-V.

Les éléments numérotés sur les figures correspondent The elements numbered in the figures correspond

aux parties indiquées ci-après.to the parts indicated below.

Le corps t de la machine repose sur des pattes 2, de forme rectangulaire ou équivalente, qui prolongent une pièce 3 à profil en U ayant une section rectangulaire avec des ailes ou c8tés latéraux 4,et présentant dans sa partie supérieure des ouvertures 5 correspondant aux roulettes 6 montées aux extrémités du dispositifs Ces roulettes sent portées par des axes 7 montés entre les catés latéraux dub. deuxième élément profilé de section rectangulaire, de dimension plus petite que le précédent, logé k l'intérieur de ceii-ci, et dont la base 9 est pourvue de trons 10 correspondant aux rouoes, lesquelles émergent partiellement k travers ces ouvertures, ce qui permets The body t of the machine rests on legs 2, of rectangular or equivalent shape, which extend a part 3 with a U-shaped profile having a rectangular section with wings or lateral sides 4, and having in its upper part openings 5 corresponding to the casters 6 mounted at the ends of the devices These casters are carried by pins 7 mounted between the side catches dub. second profiled element of rectangular section, of smaller dimension than the previous one, housed inside this, and whose base 9 is provided with sections 10 corresponding to the rouoes, which partially emerge through these openings, which allow

leur contact avec le sol, comme l'indique la figure 2. their contact with the ground, as shown in Figure 2.

Les ectes latéraux 4 de i'Lme6n extz.eu.r k profil en U comportent de larges fentes ebliques ' qui permettent aux têtes des axes 7 des roues de passer d la position hante de la figure 1 à la position basse de la figure 2, suivant qu'il The lateral ects 4 of i'Lme6n extz.eu.rk U-shaped profile have large eblique slots' which allow the heads of the axes of the wheels 7 to pass from the haunted position of figure 1 to the low position of figure 2, according to that

s'agit de maintenir les roues en position escamotée, pour immo- this is to keep the wheels in the retracted position, to immo-

biliser la machine, ou de les mettre en action en vue de son déplacement. Le passage d'une positien à l'autre (fig. 1 et 2) est obtenu à l'aide d'un levier actionné à la main, constitué par une pièce plane 14 de forme allongée, à l'extrémité de laquelle est montée la pièce rectangulaire 15 pourvue d'un rebord 16, lequel vient s'appliquer contre larête inférieure horizontale stabilize the machine, or put them into action for its movement. The passage from one positian to another (fig. 1 and 2) is obtained using a lever actuated by hand, consisting of a flat piece 14 of elongated shape, at the end of which is mounted the rectangular piece 15 provided with a flange 16, which is applied against the horizontal lower edge

de la machine, comme le montre la figure 1. of the machine, as shown in Figure 1.

A l'autre extrémité, le levier 14 comporte une partie élargie 17 en forme de palette, avec un bord courbe 23 et une saillie 24 en forme de dent, et s'articule autour de la tige 18 At the other end, the lever 14 has an enlarged part 17 in the form of a pallet, with a curved edge 23 and a projection 24 in the form of a tooth, and is articulated around the rod 18

lation du levier, dont l'action s'exerce par le bord courbe 23 contre une pièce 12 en matière synthétique, appliquée contre l'extrémité de l'élément profilé 9; de la sorte, la partie élargie horizontale 13 de cette pièce, comme on peut le voir sur les figures 1 et 2, agit comme une butée bloquant les roues en position haute, la saillie 24 du levier contribuant à cette action. lation of the lever, the action of which is exerted by the curved edge 23 against a part 12 of synthetic material, applied against the end of the profiled element 9; in this way, the enlarged horizontal part 13 of this part, as can be seen in FIGS. 1 and 2, acts as a stop blocking the wheels in the high position, the projection 24 of the lever contributing to this action.
