Abstract
Bodenstaubsauger mit Rädern, von denen mindestens eines als Lenkrolle (4) ausgebildet ist und eine Laufrolle (8) umfasst, welche in einer Aussparung (9) an einer Gleitkufe (7) mittels einer Rollenachse (10) drehbar gehalten ist, wobei die Rollenachse (10) in Achslagern (11) an den Seitenwänden (12) der Aussparung (9) aufgenommen wird und wobei die Gleitkufe (7) mittels einer zylindrischen Aufnahme (14) an einer an der Unterseite des Staubsaugers befestigten Achse (3) drehbar gehalten ist, dadurch gekennzeichnet, dass an der Unterseite des Bodenstaubsaugers mindestens eine Rippe (5, 6) angeordnet ist, welche in Richtung der Gleitkufe (7) ragt, und dass die Rippe (5, 6) auf einem Radius angeordnet sind, auf dem sich auch Übergangsbereiche (13) der Seitenwände (12) in eine Außenwand (18) der Gleitkufe (7) befinden.A vacuum cleaner with wheels, at least one of which is designed as a steering roller (4) and a roller (8), which in a recess (9) on a skid (7) by means of a roller shaft (10) is rotatably supported, the roller axle ( 10) in axle bearings (11) on the side walls (12) of the recess (9) is received and wherein the skid (7) by means of a cylindrical receptacle (14) on a fixed to the underside of the vacuum cleaner axis (3) is rotatably supported, characterized in that on the underside of the vacuum cleaner at least one rib (5, 6) is arranged, which in the direction of the skid (7) protrudes, and that the rib (5, 6) are arranged on a radius on which also transition areas (13) of the side walls (12) in an outer wall (18) of the skid (7) are located.
Description
Die Erfindung betrifft einen Bodenstaubsauger nach dem Oberbegriff des Anspruchs 1.The invention relates to a vacuum cleaner according to the preamble of
Bei Bodenstaubsaugern ist es üblich, dass der Benutzer diese während des Saugvorgangs am Saugschlauch hinter sich herzieht. Hierzu sind diese Staubsauger auf ihrer Unterseite mit Rädern ausgestattet. Zur Verbesserung der Manövrierfähigkeit ist mindestens eines dieser Räder als Lenkrolle ausgebildet, bei der eine Rolle in einer Gleitkufe gehalten ist. Dabei ist die Rolle selbst um eine in der Gebrauchslage des Staubsaugers waagerechte Achse drehbar gelagert, die Gleitkufe dreht sich um eine in Gebrauchslage senkrechte Achse, welche in der Regel an einem unteren Gehäuseteil gehalten ist. Die
Wenn der Staubsauger über Treppenstufen gezogen wird oder aus einer sogenannten Parking-Position umfällt, bewirkt das beschleunigte Gewicht des Staubsaugers eine große Kraft, welche von der Gleitkufe abgefangen werden muss. Bei ungünstigen Positionen der Gleitkufe können dabei Biegemomente entstehen, die ein Ausbrechen der Achse aus ihrer Aufnahme verursachen.When the vacuum cleaner is pulled over stairs or falls from a so-called parking position, the accelerated weight of the vacuum cleaner causes a large force, which must be absorbed by the skid. In unfavorable positions of the skid bending moments can arise, causing the axis to break out of their recording.
Der Erfindung stellt sich somit das Problem, bei einem Staubsauger der eingangs genannten Art ein Ausbrechen der Achse zu vermeiden.The invention thus raises the problem of avoiding a breaking of the axis in a vacuum cleaner of the type mentioned.
Erfindungsgemäß wird dieses Problem durch einen Bodenstaubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a vacuum cleaner with the features of
