Method and apparatus for turning a corner

Abstract

In one aspect, an apparatus for turning a corner, the apparatus being disposed adjacent to a grounded surface and comprising: a turntable platter, rotatably coupled to the grounded surface, for orienting a line-drawn trolley; a locking mechanism, disposed on the turntable platter, for preventing rotation of the turntable platter with respect to the grounded surface; a first turntable guide, removably coupled to the turntable platter, for guiding a draw line through the line-drawn trolley; a second turntable guide, removably coupled to the turntable platter, for guiding the draw line through the line-drawn trolley; a first stationary diverter, removably coupled to the grounded surface, for diverting the draw line around the line-drawn trolley; and a second stationary diverter, removably coupled to the grounded surface, for diverting the draw line around the line-drawn trolley.

1 . An apparatus for turning a corner, said apparatus being disposed adjacent to a grounded surface and comprising:
 a turntable platter, rotatably coupled to said grounded surface, for orienting a line-drawn trolley;   a locking mechanism, disposed on said turntable platter, for preventing rotation of said turntable platter with respect to said grounded surface;   a first turntable guide, removably coupled to said turntable platter, for guiding a draw line through said line-drawn trolley;   a second turntable guide, removably coupled to said turntable platter, for guiding said draw line through said line-drawn trolley;   a first stationary diverter, removably coupled to said grounded surface, for diverting said draw line toward the periphery of said turntable platter; and   a second stationary diverter, removably coupled to said grounded surface, for diverting said draw line toward the periphery of said turntable platter.   
     
     
         2 . The apparatus of  claim 1  wherein said first turntable guide is disposed tangent to a diametral line on a first side of said diametral line. 
     
     
         3 . The apparatus of  claim 1  wherein said second turntable guide is disposed tangent to said diametral line on said first side of said diametral line. 
     
     
         4 . The apparatus of  claim 1  wherein said first stationary diverter is, in a first orientation of said turntable platter, disposed tangent to said diametral line on a second side of said diametral line. 
     
     
         5 . The apparatus of  claim 1  wherein said second stationary diverter is, in a second orientation of said turntable platter, disposed tangent to said diametral line on said second side of said diametral line. 
     
     
         6 . An apparatus for turning a corner, said apparatus being disposed adjacent to a grounded surface and comprising:
 a turntable platter, rotatably coupled to said grounded surface, for orienting a line-drawn trolley;   a locking mechanism, disposed on said turntable platter, for preventing rotation of said turntable platter with respect to said grounded surface;   a first turntable guide, removably coupled to said turntable platter and disposed tangent to a diametral line on a first side of said diametral line, for guiding a draw line through said line-drawn trolley;   a second turntable guide, removably coupled to said turntable platter and disposed tangent to said diametral line on said first side of said diametral line, for guiding said draw line through said line-drawn trolley;   a first stationary diverter, removably coupled to said grounded surface and, in a first orientation of said turntable platter, disposed tangent to said diametral line on a second side of said diametral line, for diverting said draw line toward the periphery of said turntable platter; and   a second stationary diverter, removably coupled to said grounded surface and, in a second orientation of said turntable platter, disposed tangent to said diametral line on said second side of said diametral line, for diverting said draw line toward the periphery of said turntable platter.   
     
     
         7 . A method for turning a corner, said method comprising acts of:
 providing a turntable platter in a first orientation;   drawing a line-drawn trolley onto said turntable platter;   installing a first turntable guide;   installing a first stationary diverter;   unlocking a locking mechanism;   rotating said turntable platter to a second orientation;   locking said locking mechanism;   removing a second turntable guide;   removing a second stationary diverter;   drawing said line-drawn trolley off of said turntable platter.   
     
     
         8 . The method of  claim 7  wherein said act of rotating said turntable platter to a second orientation comprises drawing a draw line through said line-drawn trolley. 
     
     
         9 . The method of  claim 7  wherein said act of installing said first turntable guide comprises disposing said first turntable guide tangent to a diametral line on a first side of said diametral line. 
     
     
         10 . The method of  claim 7  wherein said act of installing said first stationary diverter comprises disposing said first stationary diverter tangent to said diametral line on a second side of said diametral line. 
     
     
         11 . The method of  claim 7  wherein:
 said act of rotating said turntable platter to a second orientation comprises drawing a draw line through said line-drawn trolley; 
 said act of installing said first turntable guide comprises disposing said first turntable guide tangent to a diametral line on a first side of said diametral line; and 
 said act of installing said first stationary diverter comprises disposing said first stationary diverter tangent to said diametral line on a second side of said diametral line.
