  • a floor cleaning device with a sweeping threshold which has a bending section at a free end, is described in EP 0 705 560 A1.
  • the sweeping threshold has a tapering from the housing in the direction of the bottom surface to be cleaned form. Upon contact with an obstacle, the sweeping threshold can bend at the free end of the bending section against the direction of movement. According to EP 0 705 560 A1, this is intended to allow obstacles to be overcome in a simpler manner without damaging the sweeping threshold.
  • a self-propelled and self-steering floor cleaning device with an adjustable in the direction of the floor surface to be cleaned sweeping threshold is described in DE 101 10 906 AI.
  • Object of the present invention is to provide an aforementioned floor cleaning device, with the bending of the sweeping threshold can be achieved in contact with an obstacle in a reliable manner.
  • This object is achieved in a generic floor cleaning device according to the invention in that the sweeping threshold comprises a fixed to the housing base member having the at least one bending portion, and connected to the base member stiffening element which forms a vergeifungsabêt arranged on the free edge, at which stiffening section the sweeping threshold more rigid than at least one bending section.
  • the return threshold can be reliably bent on contact with an obstacle as a result of the aforementioned embodiment on at least one bending section.
  • the stiffening section at the free edge of the sweeping threshold can contact an obstacle. Since the stiffening portion is more resistant to bending in relation to the at least one bending section, the stiffening section is not bent or only with very little probability, instead the base element can bend at the at least one bending section at a distance from the free edge.
  • the sweeping threshold can thus be reliably bent against the direction of travel and moved across obstacles. As a result, the risk of damage to the sweeping threshold by obstacles especially on the bending section can be avoided. Dirt can be transported in the non-bent state and preferably in the bent state over the base element in the dirt collecting. About basic element, the sweeping threshold is held on the housing.
  • the presence of the sweeping threshold with stiffening element at the free edge proves to be particularly advantageous.
  • the likelihood of the floor cleaner hitting an obstacle is reduced.
  • the user is spared to solve a stuck on an obstacle floor cleaning device of this, which improves the cleaning result and facilitates the handling of the floor cleaning device.
  • the floor cleaning appliance can sink into soft, yielding floor surfaces such as carpets. Due to the stiffening section, the sweeping threshold on the carpet pile can bend while reducing the driving resistance. The likelihood that the floor cleaner will jack up or rock is thereby reduced. This improves the cleaning result; In addition, the energy consumption of the floor cleaning device is reduced and increases the term.
  • the sweeping threshold is in particular against the straight-ahead movement in the direction of a back of the floor cleaning device bendable.
  • the sweeping threshold is preferably bent along its entire length.
  • the longitudinal direction of the sweeping threshold preferably runs in or parallel to a transverse direction of the floor cleaning device, with respect to its main direction of movement.

  • the stiffening section engages around the base element, wherein it has a region facing the bottom surface to be cleaned and an area facing away from the bottom surface. This makes it possible, for example, to protect the basic element, which Ches in relation to the stiffening element may be comparatively soft, at the bottom surface facing and facing away from the sides in the region of the free edge.
  • Position and orientation data refer in the present case to an intended use of the floor cleaning device, in which this is to be regarded as positioned on the floor surface to be cleaned in an operating position.

  • the stiffening element extends along the free edge of the sweeping threshold over the entire length of the base element. Thereby, a reliable function of the sweeping threshold can be ensured. If an obstacle contacts the free edge, it is shown in practice that the sweeping threshold can be reliably bent over its entire length at the at least one bending section.
  • stiffening element protrudes at the free edge with protruding areas over the base element at its opposite sides.
  • the sweeping threshold encompasses lateral protective elements which are connected to the stiffening element at the projecting areas and which in each case partially cover the base element at its mutually remote sides.
  • the protective elements protect the base element at its sides facing away from each other at least in sections between the free edge and the housing. This is the basic element protected against possible damage that may occur in the absence of the protective elements when an obstacle contacts the base element laterally. This is possible, for example, during a rotation or turn of the floor cleaning device, in a self-propelled and self-steering floor cleaning device.
  • the protective elements may be integrally connected to the stiffening element.

  • the base element has a first bending section and a second bending section, wherein the first bending section is arranged on a side facing the stiffening element and the second bending section is arranged on a side of the base element facing the housing.
  • This provides the possibility that the sweeping threshold is bent depending on the nature and size of an obstacle and / or condition of the bottom surface of the first bending section and / or on the second bending section. For example, it can be provided that when using the floor cleaning device on a hard, non-compliant floor surface in the absence of obstacles no bending of the sweeping threshold takes place.
  • the floor cleaning device When using the floor cleaning device on a soft, yielding floor surface - such as a carpet - in which the floor cleaning device can "sink" due to their weight, it can be provided that the sweeping threshold is bent by contact with the bottom surface on the first bending section. As a result, it can be avoided during a movement of the floor cleaning device that this jacked up as a result of the movement or rocking.
  • the Kehrschwelle For comparatively large obstacles, whether on hard, non-yielding ground surface or soft, yielding ground surfaces, the Kehrschwelle be supplemented or alternatively bent at the second bending section.

Instead of an obstacle 92 on the bottom surface 14, this situation may also occur when the floor cleaning device 12 is moved over larger thresholds, such as carpet edges.
  • a concave, parallel to the longitudinal direction 56 recess 94 is formed on the underside 30.
  • the stiffening element 60 can engage wholly or partially when the sweeping threshold 40 is bent.
  • the sweeping threshold 40 can resume its initial position due to the elasticity of the films 64 to 70.
  • the sweeping threshold 40 can again assume the unbent state.
  • the sweeping threshold 40 can again assume the state in which it is bent only on the first bending section 74, so that in a further movement of the floor cleaning device 12 whose jacking can be avoided.

Abstract

L'invention concerne un dispositif de nettoyage de sol, comprenant : un boîtier (16) ; un récipient de collecte de saletés (36), qui comporte une ouverture d'entrée des saletés (38) ; un cylindre à brosse (30) pouvant être entraîné en rotation ; et une traverse de balayage (40) associée au cylindre à brosse (30), disposée au niveau de l'ouverture d'entrée de saletés (38), laquelle traverse de balayage (40) permet d'acheminer les saletés dans le récipient de collecte de saletés (36). La traverse de balayage (40) est fixée au niveau du boîtier (16) par un bord fixe (48) et comporte un bord libre (50) ainsi qu'au moins une section de pliage (74, 76) disposée entre le bord fixe (48) et le bord libre (50), au niveau de laquelle la traverse de balayage (40) peut être pliée dans le sens inverse d'une direction de déplacement (42) du dispositif de nettoyage de sol (16). L'invention vise à proposer un dispositif de nettoyage de ce type, grâce auquel la traverse de balayage peut se plier avec une plus grande fiabilité en cas de contact avec un obstacle. A cet effet, la traverse de balayage (40) comprend un élément de base (58) fixé au niveau du boîtier, qui comporte la ou les sections de pliage (74, 76). Elle comprend également un élément de renforcement (60) relié à l'élément de base (58), lequel forme une section de renforcement (80) disposée au niveau du bord libre (50), la traverse de balayage (40) étant plus rigide en flexion au niveau de ladite section de renforcement (80) qu'au niveau de la ou des sections de pliage (74, 76).
