发明名称 Handle arrangement on a vacuum cleaner hose
摘要 A handle arrangement on a vacuum cleaner hose has an inner bushing non-rotatably attached to one end of the hose and is inserted in a handle tube and axially fixed therein such that it can rotate. Electrical leads are guided outwards from the hose and the inner bushing in a radial direction through a wall opening of the handle tube and into the cavity of a handle part. The handle part is firmly connected at both ends to the handle tube. The electrical leads are fixed so as to form a length reserve loop in the cavity. A receiving space is provided on the inner bushing, into which electrical leads from the length reserve loop are shifted when relative rotations take place between the hose and the handle tube. The possible rotation angle is delimited by stops according to the lead length available in the length reserve loop.
