Safety nosing components and manufacturing methods

Abstract

The present invention is an improved safety nosing component including a base element with channel member and a light emission element. The safety nosing component is manufactured by extrusion, co-extrusion, triple-extrusion, injection molding, insert injection molding, two-shot molding or a combination thereof. The present invention allows safety nosing components to be installed on architectural structures while also providing additional functionality.

         21 . A safety nosing component for securement to a stair architectural structure, comprising:
 a base element including a main member and a support member,
 said main member includes an inside surface, an outside surface, a first edge, a second edge, a third edge and a fourth edge; 
 said support member includes an interior surface, an exterior surface, a first border, a second border, a third border and a fourth border, wherein said main member and said support member unite at said second edge of said main member and said second border of said support member; 
   a texture element forming tread on said outside surface of said main member;   an attachment member on said inside surface of said main member, wherein said attachment member is a conduit structure to which adhesive is applied to secure the safety nosing component to the stair architectural structure;   a channel member formed by a first boundary, a second boundary including a first bevel feature and a third boundary including a second bevel feature, wherein said channel member extends from a proximate end to a distal end and is positioned on said outside surface of said main member such that said proximate end terminates at said third edge of said main member and said distal end terminates at said fourth edge of said main member;   a substrate element including a top face, a bottom face, a first side including a first reverse-bevel feature, a second side including a second reverse-bevel feature, a third side and a fourth side; and   a light emission element including an upper face, a lower face, a first wall including a third reverse-bevel feature, a second wall including a fourth reverse-bevel feature, a third wall and a fourth wall;
 said substrate element and said light emission element are positioned within said channel member such that said bottom face of said substrate element abuts said first boundary of said channel member, 
 said top face of said substrate element abuts said lower face of said light emission element and said upper face of said light emission element aligns with said outside surface of said main member, 
 said third side of said substrate element aligns with said third wall of said light emission element and said third side and said third wall further align with said proximate end of said channel member, 
 said fourth side of said substrate element aligns with said fourth wall of said light emission element and said fourth side and said fourth wall further align with said distal end of said channel member, 
 said first reverse-bevel feature of said first side of said substrate element aligns with said third reverse-bevel feature of said first wall of said light emission element and said first reverse-bevel feature and said third reverse-bevel feature mate with said first bevel feature of said second boundary of said channel member, and said second reverse-bevel feature of said second side of said substrate element aligns with said fourth reverse-bevel feature of said second wall of said light emission element and said second reverse-bevel feature and said fourth reverse-bevel feature mate with said second bevel feature of said third boundary of said channel member, 
 said base element overmolds said substrate element and said light emission element thereby securing said substrate element and said light emission element within said channel member. 
   
     
     
         22 . The safety nosing component for securement to a stair architectural structure of  claim 21 , wherein said first edge of said main member includes a bevel feature. 
     
     
         23 . The safety nosing component for securement to an stair architectural structure of  claim 21 , wherein said substrate element is constructed of a material selected from the group comprising of a white polypropylene and a white polyethylene. 
     
     
         24 . The safety nosing component for securement to a stair architectural structure of  claim 21 , wherein said base element is constructed of a material compounded with a glass fiber. 
     
     
         25 . The safety nosing component for securement to an stair architectural structure of  claim 21 , wherein said base element is constructed of a material selected from the group comprising of polyurethane, polypropylene, and nylon-polypropylene alloy. 
     
     
         26 . The safety nosing component for securement to a stair architectural structure of  claim 21 , wherein said texture element is a plurality of cleats. 
     
     
         27 . The safety nosing component for securement to an stair architectural structure of  claim 21 , wherein said light emission element is between and including ½ inches to about and including 2½ inches in width. 
     
     
         28 . The safety nosing component for securement to a stair architectural structure of  claim 21 , wherein said substrate element and said light emission element are extruded and insert molded with said base element. 
     
     
         29 . The safety nosing component for securement to a stair architectural structure of  claim 21  further comprising a texture element on said exterior surface of said support member. 
     
     
         30 . The safety nosing component for securement to a stair architectural structure of  claim 29 , wherein said texture element is tread. 
     
     
         31 . The safety nosing component for securement to a stair architectural structure of  claim 29 , wherein said texture element is an advertising constituent. 
     
     
         32 . The safety nosing component for securement to a stair architectural structure of  claim 21 , wherein said texture element further comprises an advertising constituent.
