Definitions

  • the invention relates to a floor nozzle for a cleaning device, especially for a vacuum cleaner, with a Having brush device and by operating a Handling element movable brush holder so that the brush device between a working and a Non-working position is movable.
  • Such floor nozzles are particularly associated with Household vacuum cleaners known. They mostly point in the front Nozzle section a strip-shaped brush device that, if necessary, from a non-working position into a Can be brought into the working position in which it is on the ground, attacks the carpet or the like, for example. To move is a swivel and lifting mechanism for the brush strip or the one having this Brush holder provided.
  • a disadvantage of previously known Swiveling and lifting mechanisms is the remarkably large one Overall height of the entire floor nozzle, especially in the area of Brush strip, because there on the one hand due to the to be arranged Mechanical elements, on the other hand due to the required space for retracting and extending the brush strip relatively much space is required.
  • the invention is therefore based on the problem of a floor nozzle of the type mentioned at the beginning, which is a minor Height with simplicity of the entire mechanics having.
  • the brush holder is pivotally mounted, the Swivel axis of the brush holder in the area of the brush device is arranged.
  • the swivel bearing of the brush holder on which the brush device is arranged, as is the positioning close to the brush the pivot axis enables, with particular advantage, the floor nozzle extremely low, because on the one hand due to the direct swiveling of the brush holder and on the other hand by the arrangement according to the invention the pivot axis for the movement of the brush device very little space is required, as opposed to previously known movement mechanisms.
  • a first swivel connection element on the brush holder be formed with a second one Housing part of the floor nozzle arranged pivot connector is in operative connection, the storage of Brush holder on both the upper and lower parts of the housing can be done.
  • the first swivel connector can be a cone or rib-like according to the invention Bearing approach and the second pivot connector one be the bearing approach receiving bearing, with the Allow easy rotation of the bearing boss at least in the area engaging in the storage area can have a rounded contour.
  • the spring element or elements can expediently in extension of a carrier body, which is part of the brush carrier is formed, and with their ends, if necessary by means of a molded-on engagement element, engage in the engagement receptacle of the handling element, or be connected in one piece with the handling element. It should be noted here that the training of a single spring element may be sufficient, but in With regard to the required resilience of the training several spring elements that work simultaneously for one ensure uniform movement is appropriate.
  • the lever-like section of the handling element from the bearing point thereof on the housing part to the connection point with the brush holder is shorter than the corresponding lever-like section of the brush holder.
  • the handling element which according to an expedient embodiment of the inventive concept, must be pivoted to can be arranged in a housing part of the floor nozzle, for example pivoted by 60 °
  • a stop element interacting with another element can be provided on the brush holder and / or on the handling element the stop element formed on the brush holder can be designed in the form of a recess which interacts with a stop shoulder of a housing part which engages in this to limit movement.
  • the floor nozzle 1 according to the invention shown in FIG. 1 exists of an upper housing part 2, and a lower housing part 3, these by connecting elements, not shown are attached to each other.
  • a strip-like brush device 4 is on a brush holder 5 consisting of a Carrier body 6 arranged.
  • the carrier body 6 is shown in FIG Embodiment provided a brush recess 7, in which the brush device 4 is held.
  • a first pivot connection element 8 molded in the form of a bearing boss 9, which at its The outer contour is essentially rounded.
  • Of the Bearing approach 9 engages in a bearing receptacle 10, which on Lower housing part 3 is formed.
  • The is also shown Swivel axis S1 around which the brush holder 6 and with it the brush device 4 is pivotable.
  • On the brush holder 6, a further recess 11 is also formed in which engages a stop shoulder 12 of the lower housing part 3 and limits the pivotal movement, that is, both Parts work together in the form of a stop.
  • the brush holder 5 also has an extension on the carrier body 6 the same integrally formed spring elements 13, of which only one is shown in the example shown. In in practice, however, several are expediently provided.
  • the spring elements serve to generate a restoring force, against which the swivel movement takes place.
  • the multiple spring elements 13 are at the ends by means of a web-like Engagement elements 14 connected. This web-like engagement element 14 engages in an engagement receptacle 15, which is formed on a handling element 16.
  • the Handling element 16 in the example shown an adjusting lever, is in turn about the pivot axis S2 on the upper part of the housing 2 stored.
  • the dimensioning, arrangement and storage of the brush holder 5 and the handling element 16 are chosen so that in the end positions shown in Figs. 1 and 2 the spring elements 13 are each relaxed. Now going out 1, the handling element 16 with its engagement section 17 pressed down in the direction of arrow A, the engagement receptacle 15 moves along the dashed line drawn curve K2. Starting from the axis of rotation S1 would swivel the brush holder 5 around its Pivot axis S1, the engagement element 14 and with it the entire Walk brush holder 5 along curve K1. Obviously the two curves K1 and K2 intersect. Conditionally by the arrangement of the spring elements 13, these are but deformed when pivoted and generate a restoring force, against which the pivoting has to take place.
  • the brush device is in the position shown in FIG. 2 4 as far as inside the floor nozzle 1, that she can no longer attack on the ground. Should now Floor nozzle brought back into the position shown in Fig. 1 , it would only be necessary to use the handling element with its further operating section 18 in Direction of arrow C, causing the Spring elements 13 are in turn deformed and tensioned. If the swivel is strong enough, the mechanism snaps due to the spring force generated in the corresponding another position, the brush device 4 folds in the direction of arrow D. As clearly shown in FIGS.
  • Fig. 3 shows in the form of a section Schematic diagram resulting from the configuration according to the invention the substantial reduction in the Overall height. Shown is the lower housing part 3 and an upper housing part 2a of the floor nozzle according to the invention, and a housing part 2b a floor nozzle according to the prior art with vertical displacement of the brush device. Obviously the upper housing part 2b is significantly higher with respect of the lower housing part 3 arranged as the upper housing part 2a. This is necessary in the prior art, because starting from the one in the working position Brush device 4 this vertically up into the 19 marked non-working position. In contrast, in the floor nozzle according to the invention Non-working position 20 due to the pivoting one others, as Fig. 3 clearly shows. This possibility of pivoting but allows the height to be reduced.
