Document Type and Number:
WIPO Patent Application WO/2014/018436
Kind Code:
A3
Abstract:
Example trolleys and hangers for washdown curtains are disclosed herein. An example trolley disclosed herein includes features that simplify manufacturing and promote liquid runoff to avoid bacterial growth. Some example trolleys comprise U-bolts, shoulder screws and acorn nuts. In some examples, a frame of the trolley has a nestable V-shape profile that makes the frame readily blanked and formed from sheet metal with minimal waste. In some examples, an example trolley disclosed herein has a pair of rollers that are horizontally offset to a point from which the curtain hangs so that the weight of the curtain tilts the trolley to promote liquid runoff from the trolley's frame.
