Full-extension drawer slide

Abstract

The invention comprising a full-extension drawer slide with areas 24, 26, 32, and 34 for interlocking parts. Areas 24, 26, 32, and 34 hold the parts in a relative position to allow the parts to slide within each other. There are no moving bearings or raceways present. Each full-extension drawer slide has only three separate moving parts. The unique design of this drawer slide allows for a much more compact construction, while retaining the strength of current full-extension drawer slides.

1 . A non-mechanical interlocking drawer slide, comprising:
 A. Part  10  an outer frame assembly having two angled grooves that run the full length of said part, said frame also comprises two stop areas within said frame, and said frame comprises four counter sink holes for mounting the unit to an installation point, said top and bottom angled grooves receive outer angled grooves of part  12  that further comprise said non-mechanical interlocking three-part drawer slide;   B. Part  12  is a free moving intermediate slide, said intermediate slide contains inner grooves and outer edges, said grooves and edges facilitate full movement between stop areas, thus giving full-extension capability unlike other beveled non-mechanical, interlocking drawer slides without an intermediate slide,   C. Part  14  is the load bearing slide and rides within the inner angles of part  12 , said part comprises a stop arm which contacts stop area on part  12 , that inhibits movement past stop area, said part has two counter sink holes to enable mounting of said drawer slide to said drawer.   
     
     
         2 . The outer frame, part  10 , comprising;
 D. The angled grooves set forth in  claim 2 , further characterized as angled grooves at each side of the frame the same width as part  12 , part  12  fits within said grooves.   E. Stop area in said part of  claim 2 , is designed to come into contact with stop arm on part  12 , preventing said slide from extending past its designed forward movement point.   F. Stop area in said frame of  claim 2 , is designed to come into contact as part  12  moves to the back of said frame, said stop area stops movement from extending past the back end of said part.   G. The mounting holes set forth in  claim 2 , further characterized in said housing are counter sink holes for mounting screws, location of counter sink holes are in the corners to avoid contact with other moving parts.   
     
     
         3 . Center part  12 , comprising;
 H. The center part with angled edges on the exterior sides ride within the angled grooves of part  10 , said exterior angled edges prevent said drawer slide from separating laterally from part  10  while allowing movement freely front to back, allowing for movement to the half-extended position, without this capability said drawer slide would not be able to fully extend;   I. Stop area in said part of  claim 3 , is designed to come into contact with stop arm on part  14 , preventing said slide from extending past its designed forward movement point;   J. Stop area in said frame of  claim 3 , is designed to come into contact as part  14  moves to the back of said frame, said stop area stops movement from extending past the back end of said part.   K. Part  12 , a free-floating intermediate slide, comprises outer angled edges on the exterior sides with angled grooves within the interior, the exterior sides are able to slide within the angled grooves of part  10 , and the interior grooves of part  12  hold the angled edges of part  14  that enables the three-part drawer slide to accommodate full extension.   
     
     
         4 . Load bearing part  14 , comprising;
 L. The load bearing slide, part  14 , with angled edges on the exterior sides ride within the angled grooves of part  12 , said exterior angled edges prevent said drawer slide from separating laterally from part  12  while allowing movement freely front to back, allowing for movement to the fully extended position;   M. Stop arm on the rear of said part of  claim 4 , is designed to come into contact with stop area on part  12 , preventing said slide from extending past its designed forward and backward movement points;   N. A load bearing slide which contains two counter sink holes to allow mounting the load bearing slide to said drawer, the counter sink holes allow for mounting while providing room for the slide to function without contacting the mounting screws.
