Abstract

In respect of the problem of specifying a broom head which can readily sweep up differently sized particles and mixtures of the same, a broom head comprising a basic body ( 100 ), from which clusters ( 1, 3, 5, 7, 8, 9, 10, 13 ) of bristles project, characterized in that the clusters ( 1, 3, 5, 7, 8, 9, 10, 13 ) have a cross section which is neither round nor circular.

First claim

The invention claimed is:

1. A broom head, comprising:
a main body having a width greater than a length;
a plurality of clusters of bristles projecting from the main body and spaced along the width and the length of the main body, each cluster including a plurality of bristles, wherein at least a portion of the clusters of bristles have a non-circular cross sectional shape, and wherein the clusters of bristles have at least two of an elongate cross sectional shape with rounded corner regions, a triangular cross sectional shape, a rectangular cross sectional shape, a square cross sectional shape, a kidney-shaped cross sectional shape, an oval cross sectional shape, and a V-shaped cross sectional shape;
a plurality of lamella projecting from the main body in a same direction as the clusters of bristles and disposed between a portion of the clusters of bristles, each lamella directly adjacent another lamella and arranged in a row, the plurality of lamella surrounded on all sides by the clusters of bristles; and
a receptacle on the main body configured to receive a broom handle substantially perpendicular to the width of the main body.

2. The broom head as claimed in claim 1 , wherein at least a portion of the clusters of bristles have at least one of harder bristles and stiffer bristles in a center of the clusters of bristles than in a peripheral region of the clusters of bristles.

3. The broom head as claimed in claim 1 , wherein the bristles have a diameter of between 0.4 mm to 0.6 mm.
