Method and apparatus for turning a corner

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.

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.
