Definitions

  • the locking bar and push handle are located at diametrically opposite circumferential locations of the vacuum cleaner suction pipe.
  • a bracket is provided for the mechanical movement coupling between the push handle and the holding-down device actuating the latching body, the two longitudinal legs of which are guided within a guide body which fills the annular space between the cylindrical end expansion of the outer tube and the inner tube.
  • the hold-down device must be operated against the restoring force of two springs in the disengaging direction of the locking body.
  • the invention has for its object to make such a suction pipe simpler and, if possible, easier to assemble.
  • the invention is satisfied only with a bar spring wrapping around the guide body at least on a partial circumferential length. One end of which is clamped in the guide body.
  • the bar spring causes a positive movement coupling between the hold-down device and push handle, which are arranged on two diametrically opposite sides of the vacuum cleaner suction pipe. The bar spring is biased in the locking direction of the locking body.
  • the bar spring has no special guide channels - such as e.g. for helical compression springs - required, as it is positively guided in the annular space between the guide body and the inner surface of the cylindrical outer tube end expansion.
  • An overlap zone U on the rod spring side is supported between the free ends 23 and 24 of two, approximately finger-like ribs 25, 26 running parallel to the tube axis x and opposing one another. From Fig. 1 it is to be provided that the overlap zone Ü is in the immediate vicinity of the clamping end 20 on the rod spring side, which also runs parallel to the tube axis x.

Claims (8)

  1. Tube d'aspiration (10) pouvant être rentré et déployé télescopiquement sur un aspirateur de poussière, avec un tube (11) extérieur et un tube (12) intérieur qui est assuré contre les mouvements relatifs par rapport au premier et dont la paroi présente une crémaillère (17) de couplage matricée avec des creux de couplage, avec laquelle coopère un corps (35) de couplage qui peut être désengagé en surmontant la force de rappel d'un ressort (19) au moyen d'un organe (30) de pression entraîné en un mouvement coulissant par l'intermédiaire d'une poignée (28) coulissante, tandis que l'espace annulaire formé entre un élargissement cylindrique au bout du tube (11) extérieur et le tube (12) intérieur est comblé par un corps (16) de guidage de forme tubulaire qui sert au guidage de l'organe (30) de pression, de la poignée (28) coulissante, du corps (35) de couplage et du ressort (19), et tandis que la poignée (28) coulissante d'un côté et la crémaillère (17) de couplage de l'autre côté sont prévues en des endroits de la périphérie du tube d'aspiration (10) de l'aspirateur de poussière, qui sont placés diamétralement opposés l'un par rapport à l'autre,
    caractérisé par le fait que l'organe (30) de pression est placé au voisinage immédiat de la crémaillère (17) de couplage à l'intérieur de l'espace annulaire (R) entre le tube (11) extérieur et le tube (12) intérieur, que le corps (16) de guidage retient encastrée une extrémité (20) ou les deux extrémités d'une barre de torsion (19) qui entoure en spires au moins en partie le corps (16) de guidage à l'intérieur de l'espace annulaire (R) et accouple dynamiquement l'un à l'autre l'organe (30) de pression et la poignée (28) coulissante qui passe à travers la paroi (en 32) de l'élargissement (13) en bout.
  2. Tube d'aspiration d'aspirateur de poussière suivant la revendication 1,
    caractérisé par le fait que la barre de torsion (19) entoure le corps (16) de guidage en formant côté extrémité une zone (U) en superposition sur l'ensemble de la longueur de la périphérie.
  3. Tube d'aspiration d'aspirateur de poussière suivant la revendication 1 ou suivant la revendication 2,
    caractérisé par le fait que la zone (U) en superposition dûe à la barre de torsion prend appui entre les extrémités frontales (23, 24) libres de deux nervures (25, 26) qui s'étendent parallèlement à l'axe x du tube et ont à peu près la forme de doigt orientés l'un vers l'autre.
  4. Tube d'aspiration d'aspirateur de poussière suivant l'une des revendication qui précèdent,
    caractérisé par le fait que la zone (U) en superposition se situe à proximité immédiate de l'extrémité (20) encastrée côté barre de torsion.
  5. Tube d'aspiration d'aspirateur de poussière suivant la revendication 4,
    caractérisé par le fait que l'extrémité (20) encastrée côté barre de torsion s'étend parallèlement à l'axe x du tube.
  6. Tube d'aspiration d'aspirateur de poussière suivant la revendication 5,
    caractérisé par le fait que l'extrémité (20) encastrée côté barre de torsion est retenue, enfoncée dans une rainure (22) qui, prévue dans la surface externe de l'enveloppe du corps (16) de guidage et ouverte vers l'extérieur dans le sens radial, s'étend dans le sens axial du tube.
  7. Tube d'aspiration d'aspirateur de poussière suivant l'une des revendications qui précèdent,
    caractérisé par le fait que la barre de torsion (19) s'étend en formant une ligne à peu près hélicoïdale.
  8. Tube d'aspiration d'aspirateur de poussière suivant l'une des revendications qui précèdent,
    caractérisé par le fait que la barre de torsion (19) vient en prise dans des rainures (27; 29) d'entraînement qui, prévues l'une côté poignée coulissante, l'autre côté organe de pression, sont ouvertes vers l'extérieur et s'étendent à peu près transversalement par rapport à l'axe x du tube.
