Abstract

The device has a rigid cylinder (4) made of rigid latex and rubber and overmounted of a flexible conical end (3) and overmounted of a toric flexible conical upper part (2) i.e. upper cone, curved towards a flexible latex base to provide reduction of thickness progressive towards an upper part of the device. A lower part (5) of the device with sufficient thickness is toric with curvature directed towards top, and prevents detachment of a dust recovery sachet from the cylinder.

Description

La présente invention concerne un adaptateur universel avec un sac permanent ou sac jetable. Le dispositif est constitué en un seul élément, en latex, en caoutchouc ou autre matériau uni, avec la seule différence que certaines parties de ce dispositif possèdent des épaisseurs différentes, ce qui rend les parties de ce dernier plus ou moins rigides que d'autres (voir fig. 2) ( coupe longitudinale . Ce dispositif a pour fonction d'adapter un sachet de récupération des poussières à tout type d'aspirateur (voir fig.1, fig. 2, fig. 3, fig. 5). Le dispositif est en forme de cylindre (4) rigide, surmonté à sa partie supérieure d'un cône (3) plus souple ayant une base torique (2) recourbée vers l'intérieur, recevant le tube de l'aspirateur (6) (voir fig. 3). Cette courbure torique (2) assure une parfaite étanchéité avec le tube de l'aspirateur (6) par simple contact et pression du joint contre la matière plastique du tube (6). La courbure de cette partie supérieure de l'adaptateur est faite de telle sorte et dans un sens dirigé vers le bas, c'est-à-dire dans le sens de l'expulsion des poussières dans le sachet. Ceci empêcherait le tube de l'aspirateur (6) de se dissocier de l'adaptateur sous l'effet de l'aspiration. La partie inférieure (5) du dispositif est conique avec la courbure de forme torique, dirigée vers le haut, ayant un diamètre plus grand que celui de la partie supérieure (2), ce qui permettrait de retenir le sachet (9) lors du rejet des poussières à l'intérieur sous l'effet de la pression. Le sachet récupérateur (9) vient se loger autour de la partie cylindrique rigide (4) du dispositif et se fixe par simple serrage 22927523 d'un cordeau (10) qui se bloque à l'aide d'une pastille de blocage (11) (12) assurant ainsi un étranglement du sachet (9) autour du cylindre (4) du dispositif. Le blocage du cordeau (10) se fait grâce à l'élément (8) qui représente un petit dispositif formé par un cylindre en plastique (11) possédant deux fentes sur sa surface latérale, ce qui permet au cordeau (10) d'y passer grâce à un petit diamètre. Ce cylindre (11) est logé dans un autre cylindre (12) d'un diamètre plus grand, avec deux fentes latérales jouxtant les deux se trouvant sur la face latérale du cylindre (11) voir fig. 5 Le cylindre (11) de la pastille repose sur un petit ressort (13) qui, en poussant vers le haut, assure le blocage du cordeau (10) dans les fentes latérales, assurant ainsi le serrage du sachet (9) autour du cylindre (4) du dispositif d'adaptation. The present invention relates to a universal adapter with a permanent bag or disposable bag. The device consists of a single element, latex, rubber or other plain material, with the only difference that some parts of this device have different thicknesses, which makes the parts of the latter more or less rigid than others The purpose of this device is to adapt a dust collection bag to any type of vacuum cleaner (see fig.1, Fig. 2, Fig. 3, Fig. 5). device is in the form of a cylinder (4) rigid, surmounted at its upper part a cone (3) more flexible having an O-ring base (2) bent inward, receiving the tube of the vacuum cleaner (6) (see This toric curvature (2) ensures a perfect seal with the tube of the vacuum cleaner (6) by simple contact and pressure of the seal against the plastic material of the tube (6) .The curvature of this upper part of the adapter is made in such a way and in a downward direction, that is to say in the meaning of the expulsion of dust in the bag. This would prevent the vacuum tube (6) from being disassociated from the adapter by suction. The lower part (5) of the device is conical with the upwardly directed ring-shaped curvature having a greater diameter than that of the upper part (2), which would allow the bag (9) to be held back on rejection. dust on the inside under the effect of pressure. The recovery bag (9) is housed around the rigid cylindrical portion (4) of the device and is fixed by simply clamping a cord (10) which locks with a blocking pad (11) (12) thus ensuring a constriction of the bag (9) around the cylinder (4) of the device. The blocking of the cord (10) is achieved by the element (8) which represents a small device formed by a plastic cylinder (11) having two slots on its lateral surface, which allows the cord (10) to pass through a small diameter. This cylinder (11) is housed in another cylinder (12) of larger diameter, with two lateral slots adjoining the two lying on the side face of the cylinder (11) see fig. The cylinder (11) of the pellet rests on a small spring (13) which, by pushing up, ensures the locking of the cord (10) in the lateral slits, thus ensuring the tightening of the bag (9) around the cylinder (4) of the adaptation device.

L'adaptateur universel se fixe à l'aspirateur grâce à deux languettes (1) en latex ou non assez rigide qui sont bloquées par les deux fixations (7) propres à l'aspirateur. Selon d'autre variante de réalisation, une plaque en plastique rigide à découper selon le modèle de l'ancienne cartonnette du sac aspirateur. Cette plaque s'adapte sur n'importe quel aspirateur par simple découpe de la plaque en plastique suivant le contour de l'ancien sac d'aspirateur. Un système conique et cranté dévissable permet d'adapter n'importe quel sac, le sac étant fourni (voir fig. 6). The universal adapter is attached to the vacuum with two tabs (1) latex or not rigid enough that are blocked by two fasteners (7) specific to the vacuum cleaner. According to another embodiment, a rigid plastic plate to be cut according to the model of the old cardboard vacuum bag. This plate fits on any vacuum cleaner by simply cutting the plastic plate following the outline of the old vacuum bag. A tapered and unscrewable system allows to adapt any bag, the bag being supplied (see Fig. 6).

Selon la variante de réalisation, un sac possède des cordons pour permettre de serrer et d'assurer l'étanchéité des poussières (fig. 3). Selon d'autre variante de réalisation, un sac permanent peut avoir différente forme et différente taille. According to the variant embodiment, a bag has cords to make it possible to tighten and to seal the dust (FIG 3). According to another embodiment, a permanent bag may have different shape and different size.

Un joint intégré au sac permanent assure l'étanchéité. Selon une autre variante de réalisation, un joint peut être fixé sur la plaque en plastique non limitatif, restant à adapter à la majorité du diamètre d'un tube de liaison de l'aspirateur. Selon d'autre variante encore, un système conique cranté dévissable ou non permettant d'adapter des sacs jetables ou permanents (fig. 6) 4 A seal integrated in the permanent bag ensures the seal. According to another embodiment, a seal may be attached to the non-limiting plastic plate, remaining to adapt to the majority of the diameter of a connection tube of the vacuum cleaner. According to yet another variant, a tapered notch system which can be unscrewed or not, making it possible to adapt disposable or permanent bags (FIG 6) 4

Claims
