Definitions

  • the invention relates to a vacuum cleaner with handle and adapter which receives at one end the end of a vacuum cleaner and at its other end a pipe socket of the handle and the latter is coupled via a releasable locking device, wherein via electrical couplings an electrically conductive connection from a nozzle at the free end of the vacuum cleaner suction pipe, over the vacuum cleaner suction pipe, the adapter, the handle and a flexible suction hose for the power supply of the vacuum cleaner.
  • the adapter consists of a lower part of the end portion of the vacuum cleaner suction undercut plastic strip which protrudes with a cross-sectionally U-shaped extension over the end of the vacuum cleaner suction and in the web portion of the U-shaped cross-section with a plug is provided for coupling with the socket part on the handle.
  • the plug is connected to a coiled electrical line extending along the vacuum cleaner suction tube.
  • the adapter is permanently attached to the end of the vacuum cleaner with several rivets. If this adapter exposed to bending or impact forces, z. B. at a abrupt placement on the floor or inappropriate coupling or storage of the vacuum cleaner suction tube, the adapter can break off, with the result that then not only the adapter, but the entire vacuum cleaner suction pipe has to be replaced with a new one
  • the US 6,015,298 discloses a suction hose for a vacuum cleaner, wherein within the suction hose lines for the electrical power supply of the vacuum cleaner are provided. At least one end side of the hose, an adapter consisting of two parts can be fastened, wherein a first inner adapter part can be inserted into the suction hose and a second outer adapter part can be pushed onto the suction hose. The two adapter parts can be locked together so that they can be attached to one end of the hose.
  • the guided inside the suction hose electrical lines are electrically connected in the assembled state with embedded in the surface of the outer adapter part annular contact surfaces, so that an electrical contacting of the guided inside the suction hose lines over this, the suction hose ring surrounding, contact surfaces is possible.
  • the EP 1 028 282 discloses a connecting element for corrugated hoses.
  • the connection element can be plugged onto at least one end of a ring-corrugated hose, whereby a positive and sealing latching between the connecting element surrounding the hose and the corrugated surface of the hose takes place automatically during the attachment, so that in the installed state the suction channel of the hose is connected via the connection connection of the connection element forms a common suction channel, so that, for example, a handle of a vacuum cleaner can be plugged onto the connection element.
  • the connecting element has for positive locking engagement with the undulating surface of the suction hose on flexible locking elements which engage in the troughs in the surface of the suction hose, whereby a positive connection is made.
  • the US 2006/0174440 discloses an adapter for attachment to at least one end portion of a flexible suction hose for a wavy surface vacuum cleaner, with electrical contact being made through the adapter within the vacuum cleaner Suction hose guided electrical lines is possible.
  • the lines are connected to at least two contact surfaces on the outer sides of the adapter.
  • the adapter thus serves both to contact the suction channel of a flexible suction hose with a handle, as well as to make an electrically conductive connection.
  • the adapter consists of a substantially circular tube piece and can be attached with associated fitting elements to an end portion of a flexible suction hose.
  • the adapter is formed by at least two shells, which are pivotally connected via a longitudinal axis of the vacuum cleaner suction parallel film hinge and at their free end portions via a screw in its final assembly position against the facing end of the Vacuum cleaner suction tube are braced.
  • the entire vacuum cleaner not only has a robust but also a visually pleasing shape.
  • the adapter is provided except with its tension against the pipe end of the vacuum cleaner with a rotation protection.
  • This twist protection advantageously consists of a recess at the end of the vacuum cleaner suction pipe facing the adapter and a cam of the adapter engaging therein.
  • a removal of the adapter from the end of the vacuum cleaner suction tube is prevented both by this cam and by the non-positive tension and a removal of the adapter from the pipe socket of the handle by the locking device.
  • the adapter consists of a total of three shells, which are connected to each other via two parallel to the longitudinal axis of the vacuum cleaner suction film hinges.
  • the two outer shells are about the same and the middle shell is strip-shaped. All shells have on their inner sides the shape of pitch circle segments, which surround in their Montageendlage received by them end portion of the vacuum cleaner suction pipe and the pipe socket of the handle circular. As a result, this end region of the vacuum cleaner suction pipe is protected by the adapter against deformation or other deformations.
  • the adapter nestles by the circular wrap of the end portion of both the shape of the vacuum cleaner suction pipe and the handle with the result that not only a robust, releasable coupling, but also a visually appealing connection between the handle and vacuum cleaner suction tube is created.
  • the two outer shells are provided at their end facing the handle with a projecting, in cross-section L-shaped bar in their Montageendlage a cross-sectionally U-shaped receptacle for the cross-section also U-shaped and form geometrically similar part of the handle on its underside and engage under this.
  • the U-shaped receptacle serves not only to facilitate the coupling between the adapter and pipe socket by means of the locking device, but also for the exact and torsion-free guidance of the Plug part in the socket part of an electrically conductive connection, which will be discussed below.
  • the middle part of the shell is advantageously provided in its central region with a leaf spring-like molded button for depressing the locking device on the pipe socket.
  • this button was located opposite the adapter on the outer circumference of the vacuum cleaner suction tube and thus required additional attachment. As a result, the vacuum cleaner suction remains smooth without riveting and fits fluidly and optically favorable to the overall impression.
  • the shells are provided on their inside with stiffening ribs.
  • These stiffening ribs are part-circular in shape at their free ends, in order to be able to adapt to the outer diameter of the end region of the vacuum cleaner suction tube in a correspondingly resilient manner by means of bracing.
  • the through-openings for the clamping screws and the recordings of the clamping screws are arranged on the outer shells, but not on the middle shell.
  • the shells are made of plastic, in particular polyamide (PA) or polypropylene (PP).
  • PA polyamide
  • PP polypropylene
