Toutes ces tablettes supports équipant des escabeaux ou des échelles, décrites ci-dessus et plus ou moins connues des utilisateurs 25 professionnels et domestiques, sont à dimensions fixes et insuffisantes pour des raisons d'encombrement ne permettant pas de supporter avec toute la stabilité souhaitable des éléments aux dimensions plus grandes All of these support shelves fitted to stepladders or ladders, described above and more or less known to professional and domestic users, are of fixed dimensions and insufficient for reasons of bulk, not making it possible to support with all the desirable stability of larger dimensions
que lesdites tablettes.as said tablets.
-2 La présente invention a pour objet un dispositif permettant d'augmenter à volonté la surface porteuse des tablettes supports adaptables sur les escabeaux et les échelles et, par conséquent, capables de recevoir des volumes de section plus grande, comme par exemple cer5 tains pots de peinture ou caisses à outils. Ce dispositif extensible de la tablette est réglable en dimensions par effet de coulissement dans des guides fixés sous la tablette support d'un fil rond de section suffisante -2 The present invention relates to a device for increasing at will the carrying surface of the support shelves adaptable on stepladders and ladders and, therefore, capable of receiving larger section volumes, such as for example cer5 tain pots paint or tool boxes. This extendable device of the shelf is adjustable in size by sliding effect in guides fixed under the shelf supporting a round wire of sufficient section
pour supporter les charges.to support the loads.
Ce fil rond coudé à son extrémité extérieure à l'avant de la ta10 blette, comporte deux branches qui coulissent dans des formes complémentaires d'une pièce solidaire de la face inférieure de la tablette. This round wire bent at its outer end at the front of the ta10 chard, has two branches which slide into complementary shapes of a part secured to the underside of the tablet.
De façon à éviter tout glissement intempestif sous l'effet des vibrations de ce dispositif extensible, lesdites branches sont légèrement évasées et les formes complémentaires dans lesquelles elles coulissent 15 sont légèrement obliques, nécessitant ainsi une action ferme et volontaire pour obtenir l'extension souhaitée. In order to avoid any untimely sliding under the effect of the vibrations of this extensible device, said branches are slightly flared and the complementary shapes in which they slide are slightly oblique, thus requiring firm and voluntary action to obtain the desired extension.
Ce même dispositif extensible est équipé dans sa partie extérieure This same extendable device is equipped in its external part
située à l'avant de la tablette, d'un plat permettant de rattraper le décalage de niveau entre le fil rond et la face supérieure de la tablette. located on the front of the tablet, with a dish to make up for the level difference between the round wire and the upper face of the tablet.
Ce plat est avantageusement perforé d'orifices ronds ou de fentes This dish is advantageously perforated with round orifices or slits
destinés à recevoir des outils tels que spatules, tournevis ou autres, obtenant ainsi la fonction complémentaire de râtelier porte-outils. intended to receive tools such as spatulas, screwdrivers or others, thus obtaining the complementary function of tool holder rack.
A son extrémité extérieure située à l'avant de la tablette, le fil rond est coudé vers le haut en forme de V renversé; cette forme faisant 25 ainsi à la fois office de zone de préhension pour tirer ou repousser le dispositif extensible de la tablette support et de butée pour les éléments At its outer end located at the front of the shelf, the round wire is bent upwards in the shape of an inverted V; this form thus acting both as a grip zone for pulling or pushing the extendable device from the support shelf and as a stop for the elements

Selon la figure 1, le dispositif extensible s'adapte sur une tablette 10 support (2) équipant un escabeau (1). According to Figure 1, the expandable device fits on a support shelf 10 (2) fitted to a stepladder (1).
Selon les figures 2, 3, 4 et 5, le dispositif extensible (3) réalisé en According to Figures 2, 3, 4 and 5, the expandable device (3) made of
fil rond (10), coulisse dans des formes complémentaires (4) (4') réalisées dans une pièce (8) solidaire de la face inférieure de la tablette support (2). round wire (10), slides in complementary shapes (4) (4 ') produced in a part (8) integral with the underside of the support shelf (2).
L'adaptation du dispositif extensible (3) au volume à supporter s'obtient en exerçant une action ferme et volontaire sur la forme en V renversé (7). La course du dispositif extensible (3) est limité dans le sens de la fermeture par le plat (6) qui vient en butée sur l'avant de la tablette support (2) et dans le sens de l'ouverture, par des butées (5) 20 (5') prévues respectivement à chacune des extrémités antérieures des deux branches (9) (9') qui viennent en butée sur l'orifice antérieur de The adaptation of the extensible device (3) to the volume to be supported is obtained by exerting a firm and voluntary action on the inverted V shape (7). The travel of the extendable device (3) is limited in the direction of closing by the plate (6) which abuts on the front of the support shelf (2) and in the direction of opening, by stops ( 5) 20 (5 ') provided respectively at each of the front ends of the two branches (9) (9') which come into abutment on the front orifice of
chacune des formes complémentaires (4) (4'). each of the complementary forms (4) (4 ').
Selon la figure 3, le dispositif extensible (3) a ses deux branches According to Figure 3, the expandable device (3) has its two branches
(9) (9') légèrement évasées coulissant dans les formes complémentaires 25 (4) (4'), également légèrement obliques, prévues à chacune des extrémités de la pièce (8) solidaire de la face inférieure de la tablette support (2) . Cette disposition, du fait de l'élasticité du fil rond (10) du dispositif extensible (3) permet d'obtenir un auto-freinage évitant les déplacements intempestifs dans un sens ou dans un autre. (9) (9 ') slightly flared sliding in the complementary shapes 25 (4) (4'), also slightly oblique, provided at each end of the part (8) integral with the underside of the support shelf (2) . This arrangement, due to the elasticity of the round wire (10) of the extensible device (3) makes it possible to obtain self-braking avoiding untimely movements in one direction or another.
-4 Selon les figures 2 et 3, le plat (6) solidaire du dispositif extensible (3) comporte des orifices de diverses formes tenant lieu avantageusement de râtelier destiné à recevoir des outils de type spatules, tournevis -4 According to Figures 2 and 3, the flat (6) integral with the expandable device (3) has holes of various shapes advantageously serving as a rack for receiving tools like spatulas, screwdrivers
ou autres.or others.
Selon la figure 4, le plat (6) en forme de U renversé reliant les extrémités extérieures des deux branches (9) (9') permet de rattraper le décalage de niveau entre le dessus de la tablette support (2) et le fil rond (10) lorsque ledit dispositif extensible est tiré dans le sens de l'ouverture. -5 According to FIG. 4, the flat (6) in the shape of an inverted U connecting the outer ends of the two branches (9) (9 ') makes it possible to make up for the level offset between the top of the support shelf (2) and the round wire. (10) when said expandable device is pulled in the direction of opening. -5
