Inline drain trap

Abstract

An inline drain trap is provided including an inlet component having an inlet housing element, an inlet passage connectable to an upper standard drain pipe within a plumbing fixture, an outlet component having an outlet housing element engageable with the inlet housing element to form a housing, an outlet passage extending downward from the outlet housing element and connectable to a lower standard drain pipe within the plumbing fixture, a trap cup sized for concentric positioning between the outlet housing element and the inlet passage, and a plurality of support struts extending radially outward from an outer diameter of the trap cup for maintaining vertical positioning and concentricity of the trap cup within the housing.

What is claimed is: 
     
         1 . An in-line drain trap assembly comprising:
 an inlet component including:
 a inlet housing element, and 
 an inlet passage extending upward from the inlet housing element toward a first end and extending downward from the inlet housing element toward a second end, the first end of the inlet passage connectable to an upper standard drain pipe within a plumbing fixture; 
   an outlet component including:
 a outlet housing element engageable with the inlet housing element to form a housing enclosing the second end of the inlet passage, 
 an outlet passage extending downward from the outlet housing element and connectable to a lower standard drain pipe within the plumbing fixture, and 
 a plurality of support elements extending inward from an interior surface of the outlet housing element; and 
   a trap insert sized for removable placement within the outlet housing element of the outlet component, the trap insert including:
 a trap cup sized for concentric positioning between the outlet housing element and the inlet passage, wherein the second end of the inlet passage extends into the trap cup within the housing, 
 a spacer ring disposed concentrically around and spaced apart from the trap cup and having a diameter sized to engage the plurality of support elements and the interior surface of the outlet housing element to maintain vertical positioning and concentricity of the trap cup within the housing, and 
 a plurality of support struts extending radially between an outer diameter of the trap cup and an inner diameter of the spacer ring. 
   
     
     
         2 . An in-line drain trap assembly comprising:
 an inlet component including:
 a inlet housing element, and 
 an inlet passage extending upward from the inlet housing element toward a first end and extending downward from the inlet housing element toward a second end, the first end of the inlet passage connectable to an upper standard drain pipe within a plumbing fixture; 
   an outlet component including:
 a outlet housing element engageable with the inlet housing element to form a housing enclosing the second end of the inlet passage, and 
 an outlet passage extending downward from the outlet housing element and connectable to a lower standard drain pipe within the plumbing fixture; 
   a trap cup sized for concentric positioning between the outlet housing element and the inlet passage, wherein the second end of the inlet passage extends into the trap cup within the housing; and   a plurality of support struts extending radially between an outer diameter of the trap cup and an inner diameter of the outlet housing element to maintain vertical positioning and concentricity of the trap cup within the housing.
