Drain strainer with support ribs

Abstract

The present disclosure pertains to a drain strainer for filtering debris from water as it enters a sink drain, the strainer comprising a strainer base; a debris collection chamber connected to the inner perimeter of the strainer base, the chamber forming therethrough a plurality of drainage pores configured to allow water passage through the chamber; and a plurality of support ribs connected to and vertically extending from the strainer base, wherein the ribs are configured to elevate items placed directly on the strainer, thereby facilitating unobstructed water flow beneath such items and into the debris collection chamber.

We claim: 
     
         1 . A drain strainer for filtering debris from water as it enters a sink drain, the strainer comprising:
 a strainer base;   a debris collection chamber connected to the inner perimeter of the strainer base, the chamber forming therethrough a plurality of drainage pores configured to allow water passage through the chamber; and   a plurality of support ribs connected to and vertically extending from the strainer base, wherein the ribs are configured to elevate items placed directly on the strainer, thereby facilitating unobstructed water flow beneath such items and into the debris collection chamber.   
     
     
         2 . The drain strainer of  claim 1 , wherein the strainer base has a circular geometry defined by a perimeter edge designed to rest within a sink drain, the perimeter edge being angled downward to facilitate the direction of water flow over the strainer base and into the debris collection chamber, thereby enhancing the strainer's water filtration efficiency. 
     
     
         3 . The drain strainer of  claim 1 , wherein the debris collection chamber is invertible, facilitating the removal of accumulated debris by manually applying upward pressure to the chamber from below. 
     
     
         4 . The drain strainer of  claim 1 , wherein the debris collection chamber is hemispherical with a flat base, the hemispherical shape conducive to guiding debris towards the flat base for accumulation and subsequent disposal. 
     
     
         5 . The drain strainer of  claim 1 , wherein the debris collection chamber is integrally formed with the strainer base. 
     
     
         6 . The drain strainer of  claim 1 , wherein the support ribs are arranged radially from a central point of the drain strainer. 
     
     
         7 . The drain strainer of  claim 6 , wherein the support ribs are uniformly spaced around the circumference of the strainer base, each rib positioned equidistant from adjacent ribs. 
     
     
         8 . The drain strainer of  claim 1 , wherein the support ribs comprise a non-slip surface to prevent movement of items placed on the ribs. 
     
     
         9 . The drain strainer of  claim 1 , wherein each of the plurality of support ribs comprises a base connected to the strainer base and a top opposite the base, wherein each of the support ribs is tapered with the base thicker than the top. 
     
     
         10 . The drain strainer of  claim 1 , wherein each of the plurality of support ribs has an outer end proximate to the outer perimeter of the strainer base and an inner end proximate to the inner perimeter of the strainer base, wherein the inner end is taller than the outer end such that the top of the support rib angles inwardly, such than an item resting on the support rib is angled upwardly over the debris collection chamber. 
     
     
         11 . The drain strainer of  claim 1 , wherein the base of the support rib is substantially triangular having one side proximate to the inner perimeter of the strainer base and one vertex proximate to the outer perimeter of the strainer base. 
     
     
         12 . The drain strainer of  claim 10 , wherein the triangular base of each support rib is rounded at its vertices. 
     
     
         13 . The drain strainer of  claim 10 , wherein the support ribs have a rounded apex. 
     
     
         14 . The drain strainer of  claim 1 , wherein the support ribs extend upward from the strainer base to a height sufficient to create a clearance between the bottom of a dish and the top surface of the strainer base, facilitating unobstructed water flow to the drainage pores. 
     
     
         15 . The drain strainer of  claim 1 , wherein the support ribs are constructed of a rubberized material, thereby limiting the risk of damage to items placed on the ribs. 
     
     
         16 . The drain strainer of  claim 1 , wherein the strainer base is constructed of a rubberized material, providing enhanced grip and resistance to movement when in contact with sink surfaces. 
     
     
         17 . The drain strainer of  claim 1 , wherein the drainage pores are dimensioned to block debris particles exceeding a specific size threshold, enabling only water and smaller particles to pass through. 
     
     
         18 . The drain strainer of  claim 1 , wherein the drain strainer is constructed from materials with antimicrobial properties. 
     
     
         19 . The drain strainer of  claim 1 , wherein the drainage pores are positioned in concentric circles within the debris collection chamber. 
     
     
         20 . A method of manufacturing a drain strainer, the method comprising:
 injection molding a material to form a strainer base with a plurality of support ribs and a debris collection chamber;   wherein the support ribs extend vertically from the strainer base at a specific height and contour for elevating items placed directly on the strainer, facilitating unobstructed water flow to the drainage pores; and   wherein the debris collection chamber is molded with plurality of drainage pores sized to allow water passage while preventing the passage of debris.
