Embodiment Construction

[0020] figure 1 A wheel 1 is shown, comprising a hub 2 and a rotor body 3, wherein the rotor body 3 has a running surface 4 on the outer peripheral side.

[0021] The hub 2 consists of plastic. The impeller body 3 is composed of a foamed elastomer. A cavity of annular configuration is arranged between the hub part 2 and the rotor body 3 .

[0022] The working surface 4 is formed by sections 5 , 6 , wherein the sections 5 , 6 are of substantially (planar) planar design. The first section 5 is inclined towards one end face 7 of the rotor body 3 and the second section 6 is inclined towards the other end face 8 of the rotor body 3 . In this case, the first section 5 and the second section 6 each form a triangle, wherein the first section 5 and the second section 6 adjoin one another linearly along the sides. Abutment edges 9 are formed in the linear contact regions of the sides, which form a contact area with the ground on which the wheel 1 moves.

[0023] The abutting edges ...

Abstract

The invention relates to a wheel (1), comprising a hub part (2) and a rotor body (3), which has a running surface (4) on the outer circumferential side, the running surface (4) being formed by a plurality of segments (5, 6), the segments (5, 6) being designed in a substantially top-like manner, the first segment (5) being inclined towards one end face (7) of the rotor body (3) and the second segment (6) being inclined towards the other end face (8) of the rotor body (3), the invention further relates to a wheel-guided household appliance having at least one wheel.

Description

technical field [0001] The present invention relates to a wheel comprising a hub and a rotor body having a working surface on the outer peripheral side. Background technique [0002] The problem with autonomously traveling, wheel-guided household appliances, such as cleaning robots, is that they have only limited climbing capabilities. If the cleaning robot travels vertically or at an acute angle towards an edge, the cleaning robot cannot usually go over this edge, even if the edge is not particularly high. In this regard, depending on the design of the household appliance, it may not be possible to cross inherently relatively low edges, such as carpet edges. In this case, the household appliance cannot reach and, for example, clean the face lying opposite the edge. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a wheel which has an improved climbing ability. [0004] Said task is solved by the features of claim 1 . The dependent cl...
