Angle adjustable retaining wall and fencing system

An apparatus for creating an angle adjustable wall comprising:

• one or more posts, each having a first end, a second end, an outer surface, and a primary slot within said outer surface;
• and
• one or more planks each having a first end, a second end and a thickness,
• one or more of said ends of said planks inserted into said primary slot of said one or more posts,
• said primary slot having an opening on said outer surface which forms a slot face,
• said slot face having two edges which form fulcrum points,
• said edges separated greater than said thickness of said one or more inserted planks but not so great that said edges cannot operate as said fulcrum points,
• said primary slot further having a first side wall and a second side wall intersecting respectively each of said two edges which form said fulcrum points and angled outward and away from said fulcrum points and said ends of said planks such that said first side wall and said second side wall are separated a greater distance at all points other than at said two edges which form fulcrum points,
• said primary slot further having a back wall intersecting and connecting said first side wall and said second side wall and shaped to allow said plank to angularly move on said fulcrum points,
• said back wall having a subslot having a width slightly greater than said thickness of said end of said plank within said primary slot;
• and
• one or more pins slideably mounted within one or more holes near said end of said plank and within said primary slot, whereby said pins butt against said side walls to hold said plank within said primary slot.

A method for forming an angle adjustable wall, the steps comprising:

• forming one or more planks having a first end, a second end, a thickness, and one or more plank holes near said ends at a first distance from said respective end;
• and
• forming a primary slot in a post;
• the steps of forming of said primary slot comprising;
• forming a slot face opening having a width in an outer surface of said post, said width wider than said thickness of said plank;
• and
• forming within said post a first side wall and a second side wall which intersect said slot face and form fulcrum points at said intersection whereby said plank thickness is capable of fitting through said fulcrum points;
• and
• angling said side walls away from said fulcrum points thereby ensuring a distance between said side walls that is greater than said point of intersection and greater than said plank thickness;
• and
• forming and shaping a back wall between and connecting said side walls, whereby said primary slot has a second distance from said back wall to said slot face greater than said first distance from said plank holes to said respective plank end;
• and
• forming one or more pins capable of slidably fitting into said one or more plank holes and of sufficient length to contact said side walls when said plank end having said pins is inserted into said primary slot;
• and
• inserting said one or more pins into said plank holes;
• and
• sliding said plank end having said pins into said primary slot whereby one or more of said pins contact said side walls;
• and
• angularly moving said plank in relation to the plain of the said slot face whereby said plank reaches a position desirable for the application.
