  • the respective button can first be inserted into its installed position. This button can engage the relevant section of its bearing edge with the associated counter-bearing section. The final securing of the relevant bearing point is then carried out by inserting a cover which bears the counter bearing web which brings about the end of the bearing. The respective button can thus be inserted flush in the housing contour in question.
  • the cover can also be used as a display panel for the operating states selectable by the button buttons, and its design can be adapted to different equipment features. This makes it possible to provide different control panel variants.
  • the counterbearing web on the cover is in contact with an attachment of the button that lies laterally in the axial direction of the button pivot axis next to a bearing point of the button on the button support plate.
  • the actual bearing point can be designed in a simple manner and the function against loosening of the bearing point against falling apart can be carried out in a function-appropriate manner.
  • Appropriate lugs and counterbearing webs can also be provided on both sides of the bearing point in order to achieve a stable bearing structure by means of three-point support.
  • the button has a relatively large length in the direction of its bearing edge, it is expedient to axially away from the first bearing a further bearing with a also in the manner of a To provide pivot bearing designed pivot bearing to which a self-locking hook latch arrangement is assigned, which secures the pivot bearing in its working position according to the function of the counter bearing web.
  • the button can thus extend beyond the cover in the direction of its bearing edge.
  • This hook latching device can be formed by a retaining web fixed to the housing, which is undercut on its edge opposite the open side of the cutting edge bearing by a latching web arranged on the button.
  • the undercut edge is preferably placed close to the plane of the pivot axis of the button, in order to only have to overcome rolling friction and little sliding friction when pivoting the button.
  • the side edge of the button opposite the cover or the bearing edge can be provided with at least one laterally protruding stroke limiting lug which engages under a stop fixed to the housing. This stop holds the key button, which can be actuated against the force of a return spring, in the non-actuated state in its inoperative position in relation to the device housing.
  • Counter bearing webs for adjacent key buttons are preferably provided in mirror-image arrangement on two opposite side edges of the cover hood.
  • cover it is expedient, at least also on a third side edge of the cover, to provide a counterbearing web for at least one further key button, which is then arranged between the portions of the button buttons laterally projecting from the cover and is also secured by the cover in the storage area.
  • the cover can in particular be designed as a display panel to visually indicate the work functions to be triggered or triggered with the key buttons to represent. This cover can be adapted to changing key functions without having to change its mechanical structure with regard to securing the key buttons.
  • buttons 2 On the top of the housing 1 of a vacuum cleaner, which is at the top during operation, there are button buttons 2 in the area of the rear end of the housing during operation, which extend, for example, over about a third of the length of the housing 1 and are each arranged close to a longitudinal side edge 3 of the housing 1 are. Between these buttons 2 there is a rectangular cover 4, the side edge 6 of which runs parallel to the rear surface 5 of the housing and is arranged at a distance from the rear surface 5. The buttons 2 extend to the rear edge 5 of the device housing 1 beyond the cover 4. A surface is thus formed between these protruding sections of the key buttons 2 and the side edge 4 and the rear edge 5, in which at least one additional element is arranged.
  • This additional element can be a control element holder 7 according to FIGS.
  • buttons 1a and 1c or further key buttons 8 according to FIG. 1b.
  • These additional elements 7, 8 are connected to the cover 4 analogously to the key buttons 2.
  • the key buttons 2, the additional elements 7, 8 and also the cover 4 are preferably located in a common envelope surface with a cover 9, which covers a dust collection space 12.
  • the cover 4 also carries symbols, light fields or other display elements on its upper side which indicate the operating state set or to be set by means of the buttons or additional elements.
  • the vacuum cleaner housing 1 is provided in one piece with a support plate 10, on which these control elements are held, in the area of the control device 2, 4, 7, 8 on its upper side during operation.
  • a blower chamber 11 for receiving a motor blower which sucks filtered air out of a dust bag chamber 12 which is arranged in the longitudinal direction of the housing 1 and can be closed with the lid 9.
  • An arcuate, upward-facing shape 13 of the support plate 10 projects into the space covered by the cover 4.
  • On the upward-facing surface of the support plate 10 there are guide walls 14 for centering vertical side walls 15 of the cover 4. In the guide walls on opposite guide walls 14, latching hooks 16 are provided which engage in corresponding latching recesses 17 in the cover 4 and are the same in their Lock the working position.
  • bearing webs 18, 19 On the top of the support plate 10 there are also bearing webs 18, 19 which, in the manner of cutting edge bearings, have bearing shells which are open at the top and are provided for the pivotable mounting of the button buttons 2, 8.
  • bearing webs 18 and 19 For each key button, two bearing webs 18 and 19, which are spaced apart from one another in the axial direction, are provided, the bearing axis for the key buttons 2 being arranged closely to the adjacent guide walls 14 and parallel thereto, while the bearing webs 19 are located in the region of the side edge 6 of the cover 4.
  • the key buttons 8, which are arranged next to one another transversely to the longitudinal axis of the device, near the longitudinal side edge 6 are equipped with a bearing edge 20 engaging from above into the bearing shell of the bearing webs 19, about which the respective key button 8 can be pivoted.
  • the buttons 8 and 2 engage on their opposite side with a stroke limit stop 21, a stop 22 fixed to the housing so that the same can pivot against the force of a return spring 23 toward the support plate 10 by pressing the top of the buttons 2.8.
  • a counter-stop 24 also engages with the stop 22 fixed to the housing when the key 2, 8 is depressed and thus limits the key stroke in the opposite direction.
  • the buttons 2 also engage in the same way with corresponding bearing edges 10 in the associated bearing webs 18 from above.
  • buttons 2, 8 in the area of the bearing edges 20 are provided with laterally projecting shoulders 25, which in the case of the button buttons 8 according to FIG 5 are designed as a molded paragraph.
  • the cover 4 holds the respective counter-bearing web 26 via paragraph 25, the associated bearing edge 20 in engagement with the upwardly open bearing web 18, 19.
  • the buttons 2, 8 can therefore be inserted in a simple manner from above into their working position during assembly and are held pivotably in this working position by subsequently fitting the cover 4 over the counter bearing webs 26.
  • each bearing web 18 that has its own counter bearing web fixed on the support plate 10 26.1 assigned.
  • the counter-bearing web 26 or 26.1 assigned to each bearing web is arranged laterally next to the associated bearing web 18 in the axial direction of the key-pivot axis.
  • the bearing point with the bearing web 26.1 also forms a bearing point with a swivel bearing designed in the manner of a cutting edge bearing and the associated paragraph 25 with the bearing web 26.1 fixed to the housing forms a hook catch arrangement which, when plugged together, snaps into one another by utilizing the material elasticity with a corresponding compressive force.
