1.-2. Vacuum cleaner head

Abstract

Main appearance characteristics lie in the shape of the whole product, the pattern and the camber of the top surface, as well as the configuration of the area near the rolling brush on the right and left sides; design 1 is indicated as a principal design and design 2 is indicated as a variant; reproductions 1.9 and 2.9 are enlarged views of portions of the reproductions 1.3 and 2.3, respectively; dash-dot lines illustrate boundaries of enlarged portions and form no part of the claimed designs; cutting surfaces form lines gradually disappearing on the surfaces to provide smooth transition between surfaces.
