Definitions

  • the invention relates to a plug-in coupling for the pivotable connection piece of vacuum cleaner accessories for connecting to the suction port of the vacuum cleaner, the locking between the connection piece and suction port being effected by a locking part and the actuation of the locking part by a push button arranged away from the locking part.
  • Such locks are known from DE-PS 1 450 445.
  • a type of hook trap is provided on the connecting piece of the vacuum cleaner accessory, which is connected via a lever to a remote push button.
  • a disadvantage of this arrangement for the user is that he has to bend down deeply when disconnecting in order to reach the pushbutton. He must then pull the other side of the connection at the same time to release the connection.
  • the object of the invention is to create a connection which avoids the disadvantages of use which are present in the prior art and which can be solved in a simple manner simply by moving the connection itself.
  • claims 2 and 3 show embodiments of the invention. Characterized in that an elastic retaining lug is arranged on the connecting piece, it is also possible to hang up a vacuum cleaner together with the vacuum cleaner accessory part without the connection being unintentionally released.
  • the invention thus has the advantage that the user can easily disconnect the connection between the vacuum cleaner and the vacuum cleaner accessory part or the suction pipe and accessory part by pivoting without having to bend down.
  • Fig. 1 shows the work with a so-called stick or hand vacuum cleaner (1), on which a vacuum cleaner accessory (2) is arranged.
  • a vacuum cleaner accessory (2) is attached with its connecting piece (3) to the suction piece (4) of the stick or hand-held vacuum cleaner (1).
  • This area is shown more clearly in the enlargement.
  • the user must now, if he Vacuum cleaner accessory (2), press the push button (5) to detach the vacuum cleaner accessory (2) from the stick or hand-held vacuum cleaner (1). To do this, he has to bend down.
  • a contact surface (6) is arranged in the area of the push button (5) on the vacuum cleaner accessory (2). If the user now, according to FIG.
  • Fig. 3 shows the connection in the locked state.
  • the connector (3) of the vacuum cleaner accessory (2) and the suction connector (4) of the vacuum cleaner, not shown, are pushed into each other and connected to each other by the locking button (7) protruding from the connector (3).
  • This locking button (7) is attached to a lever (8) and pressed outwards by the spring (9).
  • An intermediate lever (10) which is integrally connected to the push button (5), engages on this lever (8).
  • a contact surface (6) is formed on the housing (11) of the vacuum cleaner accessory part (2). If the connecting piece (3) with the suction piece (4) of the vacuum cleaner (not shown) is now pivoted into the vertical and also pushed forward, as shown in FIG. 4, the push button (5) runs against the contact surface (6).
  • the integrally formed on the push button (5) intermediate lever (10) is pivoted and presses the end (12) of the lever (8) in the other direction, so that the locking button (7) arranged on the lever (8) is pulled inwards and the Locking opening (13) in the suction port (4) releases.
  • the suction nozzle (4) can thus be removed from the connection nozzle (3) in the direction of the arrow.
  • Fig. 5 shows an enlarged individual representation of the area of the lock between the connection piece (3) and suction piece (4).
  • the lever (8) carries the locking button (7) which is supported by the spring (9).
  • the suction port (4) is the locking opening (13), which receives the locking button (7) in the locked state.
  • an elastic retaining lug (14) is fixed to the connecting piece (3), which protrudes into the area of the locking opening (13) and passes through a locking slot (15) through the locking button (7).
  • This retaining lug (14) prevents the connection from being unintentionally released. This could happen when the user brings the vacuum cleaner upright to hang it together with the vacuum cleaner accessory (2). Due to the short vertical position, the connection is released for a short time, and it could happen that the vacuum cleaner accessory (2) would slip when hanging up. This prevents the retaining lug (14), which carries the weight of the vacuum cleaner accessory (2) without loosening the connection.
  • Fig. 6 shows again the vacuum cleaner accessory (2) with connection piece (3). It shows the locking button (7), which is penetrated at the bottom by the retaining lug (14). The push button (5) is at the level of the contact surface (6) and can run against it.
  • Such connections are of course conceivable for all vacuum cleaner connections, for example also for sledge vacuum cleaners, in which the vacuum cleaner accessory is not attached directly to the connecting piece of a vacuum cleaner, but to a suction pipe.
