Articulating roller arm assembly

Abstract

An articulating roller arm assembly comprising a single integral piece cantilever beam with a span section and a throw section, with the span section oriented substantially transverse the throw section. A first distal end of the throw section and a distal end of the span section form a bend of the single integral piece cantilever beam. The articulating roller arm assembly further including a first wheel that is coupled with a first distal end of the throw section, and a second wheel that is coupled with a second distal end of the throw section.

What is claimed is: 
     
         1 . A shower enclosure, comprising:
 a track configured for guiding a roller along a longitudinal axis of the track;   the track includes a notch that is positioned at a mid-length of the track that opens access to the track for installing and removing the roller onto and from the track, after the track is installed; and   the track further includes at least one stopper for preventing entry of the roller into the notch.   
     
     
         2 . The shower enclosure as set forth in  claim 1 , wherein:
 the notch has a lower portion that is defined by a lower cut section of the track.   
     
     
         3 . The shower enclosure as set forth in  claim 2 , wherein:
 the track is part of a header.   
     
     
         4 . The shower enclosure as set forth in  claim 1 , wherein:
 the notch has an upper portion that is defined by an upper cut section of the track.   
     
     
         5 . The shower enclosure as set forth in  claim 4 , wherein:
 the track is part of a sill.   
     
     
         6 . The shower enclosure as set forth in  claim 1 , wherein:
 the track has a straight portion and a curved middle portion.   
     
     
         7 . The shower enclosure as set forth in  claim 1 , wherein:
 the notch is positioned at a curved middle portion of the track.   
     
     
         8 . A shower enclosure, comprising:
 a header; and   a sill;   the header and the sill have a respective first track and a second track that are configured for guiding a roller along a longitudinal axis of the first track and the second track;   the first track and the second track include a respective first and second notch that are positioned at a mid-length of the respective first and second track that open access to the first and second tracks for installing and removing the rollers onto and from the first track and the second track after the header and the sill are installed;   the first notch of the first track has a lower portion that is defined by a lower cut section of the first track;   the second notch of the second track has an upper portion that is defined by an upper cut section of the second track; and   the first track or the second track further include at least one stopper for preventing entry of a roller into the first or the second notch.   
     
     
         9 . The shower enclosure as set forth in  claim 8 , wherein:
 the header and the sill have a straight portion and a curved middle portion.   
     
     
         10 . The shower enclosure as set forth in  claim 8 , wherein:
 the first and the second notch is positioned at a curved middle portion of the first track and the second track.
