Description

La présente invention se rapporte à un embout d'aspirateur de poussière permettant de nettoyer sélectivement des sols à revêtements textiles ou des sols durs, cet embout étant équipé d'une plaque de fond fixe en vue de nettoyer des sols à revêtements textiles, ainsi que d'une couronne amovible porte-brosses en vue d'aspirer sur des sols durs. The present invention relates to a dust vacuum cleaner nozzle for selectively cleaning textile-coated floors or hard floors, this nozzle being equipped with a fixed bottom plate for cleaning textile-coated floors, as well as a removable brush holder crown for vacuuming on hard floors.

On connaît depuis longtemps, pour des aspirateurs de poussière ménagers, des embouts dénommés embouts combines et à l'aide desquels, en utilisant alternativement une plaque de fond fixe ou une couronne mobile porte-brosses, il est pos#sible d'aspirer la poussière soit sur des sols à revêtements textiles, soit sur des sols durs. It has been known for a long time, for household dust vacuum cleaners, nozzles called combined nozzles and with the help of which, by alternately using a fixed bottom plate or a movable crown brush holder, it is possible # suck dust either on textile-coated floors or on hard floors.

Or, dans ce type d'embouts, la couronne mobile porte-brosses doit remplir différentes fonctions lorsqu'on passe l'aspirateur sur des sols durs. However, in this type of nozzle, the mobile brush holder crown must fulfill different functions when vacuuming hard floors.

Elle doit supporter le poids de l'appareil, absorber les forces de mise en mouvement, et compenser l'usure grâce à des cotes appropriées, c'est-à-dire gracie à sa longueur initiale. It must support the weight of the device, absorb the forces of movement, and compensate for wear through appropriate dimensions, that is to say free from its initial length.

L'inconvénient extrême réside alors dans le fait que, précisément pour le dernier point cité, il convient de satisfaire à deux critères agissant à l'opposé l'un de l'autre. The extreme disadvantage then resides in the fact that, precisely for the last point cited, it is necessary to satisfy two criteria acting in opposition to each other.

D'une part, la longueur des brosses doit être grande pour compenser l'usure et, d'autre part, il faut s'efforcer de disposer la plaque de fond le plus près possible du sol dur en vue de maintenir la puissance d'aspiration. On the one hand, the length of the brushes must be great to compensate for the wear and, on the other hand, it is necessary to endeavor to have the bottom plate as close as possible to the hard ground in order to maintain the power of aspiration.

Si l'on satisfait à la première condition, la plaque de fond se trouve éloignée de la surface du sol dur, et la capacité d'aspiration est mauvaise. If the first condition is met, the bottom plate is far from the surface of the hard floor, and the suction capacity is poor.

Si l'on satisfait à l'autre condition, c est à-dire si l'on raccourcit les brosses, la plaque de fond peut exercer des frottements sur la surface du sol dur lorsque lesdites brosses sont usées. If the other condition is satisfied, that is to say if the brushes are shortened, the bottom plate can exert friction on the surface of the hard floor when said brushes are worn.

L'invention a par conséquent pour objet-de réaliser un embout d'aspirateur de poussière du type susmentionné, de façon que, même en cas d'usure de la couronne porte brosses, l'intervalle séparant la tale de fond et la surface du sol dur soit le plus réduit ptssible. The object of the invention is therefore to achieve a dust vacuum cleaner nozzle of the aforementioned type, so that, even in the event of wear of the brush-holder crown, the interval separating the bottom plate and the surface of the hard soil is the most reduced possible.

Conformément à l'invention, cet objet est atteint par le fait qu'une plaque supplémentaire disposée sur le support de la couronne à brosses est déplacée conjointement à ce support, des organes de roulement étant installés sur cette plaque. Selon d'autres caractéristiques avantageuses de l'invention, lesdits organes de roulement peuvent traverser de part en part la plaque de fond fixe lorsqu'ils sont sortis ou déployés.Ledit support de la couronne à brosses peut reposer avec jeu sur ladite plaque supplémentaire et être relié au boîtier de l'embout par des ressorts. En outre, ledit support de la couronne à brosses peut être relié par des ressorts à ladite plaque supplémentaire. According to the invention, this object is achieved by the fact that an additional plate disposed on the support of the brush crown is moved jointly with this support, rolling members being installed on this plate. According to other advantageous characteristics of the invention, said rolling members can pass right through the fixed bottom plate when they are extended or deployed. Said support of the brush crown can rest with play on said additional plate and be connected to the end cap housing by springs. In addition, said support for the brush crown can be connected by springs to said additional plate.

L'invention va à présent être décrite plus en détail à titre d'exemples nullement limitatifs, en regard des dessins annexés sur lesquels
la figure 1 est une coupe schématique d'un embout conformément à l'invention, dans lequel une couronne à brosses est rétractée
la figure 2 est une coupe correspondant à la figure 1 et représentant ladite couronne à l'état sorti et
la figure 3 illustre une variant de réalisation de l'embout, dans laquelle ladite couronne à brosses est chargée élastiquement.
The invention will now be described in more detail by way of non-limiting examples, with reference to the appended drawings in which
Figure 1 is a schematic section of a tip according to the invention, in which a brush crown is retracted
FIG. 2 is a section corresponding to FIG. 1 and representing said crown in the extended state and
FIG. 3 illustrates a variant embodiment of the endpiece, in which said brush crown is loaded elastically.

La figure 1 illustre en coupe un boîtier 1 d'embout d'aspirateur de poussière qui, d'une manière classique dans ce ce qu'on appelle des "embouts combinés" normaux, comporte une plaque de fond fixe 2 et une couronne 3 à brosses amovible. Cette couronne 3 à brosses est fixée à un support 4 mobile vers le haut et vers le bas. Audessous de ce support 4, se trouve une plaque supplémentaire 5 qui est également montée à va-et-vient vertical et sur laquelle sont disposés des organes de roulement 6 (dont deux sont illustres). FIG. 1 illustrates in section a housing 1 of a dust vacuum cleaner nozzle which, in a conventional manner in what are called normal "combined nozzles", comprises a fixed bottom plate 2 and a crown 3 to removable brushes. This crown 3 with brushes is fixed to a support 4 movable upwards and downwards. Below this support 4, there is an additional plate 5 which is also mounted toggle back and forth and on which are arranged rolling elements 6 (two of which are illustrated).

La figure 1 illustre aussi le mode de fonctionnement sur un sol 7 recouvert d'un tapis. Dans ce cas, le support 4 avec sa couronne 3 à brosses, ainsi que la plaque 5 avec ses organes de roulement- 6 sont rétractés dans le boîtier 1 de l'embout et la plaque de fond fixe 2 repose sur le sol 7 recouvert d'un tapis. Lorsqu'il y a lieu d'aspirer la poussière sur un sol dur 8, aussi bien le support 4 de la couronne que la plaque 5 sont déployés par un mécanisme (non représenté). Ainsi, la plaque 5 est verrouillée après son déploiement et, grâce aux organes de roulement 6 appliqués sur le sol dur 8, elle assure un espacement constant entre ce sol 8 et la plaque de fond 2 (figure 2). Figure 1 also illustrates the operating mode on a floor 7 covered with a carpet. In this case, the support 4 with its crown 3 with brushes, as well as the plate 5 with its rolling members - 6 are retracted into the housing 1 of the nozzle and the fixed bottom plate 2 rests on the ground 7 covered with 'a carpet. When it is necessary to vacuum the dust on a hard floor 8, both the support 4 of the crown and the plate 5 are deployed by a mechanism (not shown). Thus, the plate 5 is locked after its deployment and, thanks to the rolling members 6 applied to the hard floor 8, it ensures constant spacing between this floor 8 and the bottom plate 2 (Figure 2).

Cet espacement doit alors être choisi le plus modeste possible en vue d'augmenter la force d'aspiration. This spacing must then be chosen as small as possible in order to increase the suction force.

Dans cette forme-de réalisation, le support 4 de la couronne à brosses n'est pas relié à la plaque 5 et il est mobile librement. En d'autres termes, ladite couronne 3 porte sur le sol 8 et elle peut,#conjointement audit support 4, effectuer librement un mouvement alternatif dans le sens vertical.In this embodiment, the support 4 of the brush crown is not connected to the plate 5 and it is freely movable. In other words, said crown 3 bears on the ground 8 and it can, # together with said support 4, freely perform an alternating movement in the vertical direction.

La figure 3 montre une autre forme de réalisation. Figure 3 shows another embodiment.

Dans ce cas, le support 4 de la couronne à brosses est relié au bottier 1 de l'embout par l'intermédiaire de ressorts 9. De la sorte, d'une part la couronne 3 à brosses est pressée contre le sol 8 avec une certaine force pouvant excéder la seule force de la pesanteur et, d'autre part, le système est amorti de manière que ledit support 4 n'accuse pas de vibrations. In this case, the support 4 of the brush crown is connected to the case 1 of the nozzle by means of springs 9. In this way, on the one hand the crown 3 with brushes is pressed against the ground 8 with a some force may exceed the only force of gravity and, on the other hand, the system is damped so that said support 4 does not accuse vibrations.

Naturellement, ce type de réalisation peut également être tel qu'on intercale entre le support 4 de la couronne et la plaque 5 de courts ressorts remplissant la fonction des ressorts 9. Cette forme de réalisation n'est toutefois pas représentée sur les dessins. Naturally, this type of embodiment can also be such that there is interposed between the support 4 of the crown and the plate 5 of short springs fulfilling the function of the springs 9. This embodiment is however not shown in the drawings.

Il va de soi que de nombreuses modifications peuvent être apportées à l'embout décrit et représenté, sans sortir du cadre de l'invention.  It goes without saying that many modifications can be made to the nozzle described and shown, without going beyond the ambit of the invention.
