In accordance with FIGS. 12 and 13, spring elements 20 are provided or formed on the lower side of the covering part 13 a which are supported on the upper side of the projection 11 a. The spring elements 20 are compressed during external loading of the covering part 13 a and guarantee that the covering part is forced back into its initial position after de-loading. In accordance with FIG. 12, the spring element 20 is formed by a strap-like shackle held at both ends on the covering part 13 a. In FIG. 13, a double S-shaped support is provided as spring element which is mounted on its upper end to the covering part 13 and is supported with its lower end on the projection 11 a.
In accordance with FIG. 14, the bridge 13 b of the bristle carrier 13 is formed sectionally as bellows 21 thereby enabling tilting of the covering part 13 a, having the bristles 12, relative to the projection 11 a during use without the danger that the bristle carrier 13 slides off from the projection 11 a. This provides good, resilient support of the bristles, even on an inclined cleaning surface.
FIG. 30 shows an embodiment wherein a further dividing wall 13 d extends between the inner wall of the bridge 13 b of the bristle carrier 13 below the covering part 13 a such that the cavity 14 is formed within the bristle carrier 13 between the upper covering part 13 a and the lower dividing wall 13 d. The further development shown in FIG. 31 is provided with a storage region 25 for a medium to be applied which is located below the cavity 14 in which a foamed insert 24 is disposed. The cavity 14 is separated from the storage region 25 by a dividing wall 31 provided with passages 26. The medium may flow from the storage region 25 through the passages 26 into the foamed insert 24 of the cavity 14 and is delivered therefrom to the bristles 12 via passages 16 in the upper covering part 13 a.
As shown in FIG. 32, the cavity 14 may be subdivided by inner dividing walls 32 into several separate chambers 14 a, 14 b, 14 c which can accommodate various media which flow together and react following exit.
