发明名称 Telescopic toilet paper holder
摘要 The present invention relates to an improved telescopic toilet paper roll holder which substantially deadens the sound of a roll of toilet paper while being rotated; self-aligns and snuggly holds either a uniform or misshaped roll of toilet paper in place, preventing axial play and mutilation of the paper edges; produces a slight drag while being rotated, preventing paper runaway. This improved holder is comprised of a foamed polymer tube encompassing two hollow cylinders having slightly different diameters, nested together through their inside ends and supporting felt covered pintles on their outside ends, with a helical compression spring inside the larger cylinder urging both cylinders to extend axially; cylinders are provided with a protuberant to keep them from coming apart.
