Abstract
An object having a plurality of negative curvatures comprising a plurality of planar sections adjoined together by locking segments.
Claims21
A method for the assembly of surfaces of negative curvature comprising the steps of:
- providing plurality of planar sections, each planar section having a first edge and opposing second edge;
- said first edge having a first set of locking segments;
- said first set of locking segments comprising a plurality repeating shapes with each shape defining a plurality of openings;
- said second edge having a second set of locking segments;
- said second set of locking segments comprising a plurality repeating shapes with each shape defining a plurality of openings;
- said first set of locking segments have a different shape than said second set of locking segments;
- and
- creating a negative curvature by attaching said planar sections together by inserting said first set of locking segments into the openings defined by a second set of locking segments of an adjoining planar section and by inserting said second set of locking segments into the openings defined by a first set of locking segments of an adjoining planar section.
