Water catchment device for umbrella

Abstract

Provided is a water catchment device for an umbrella, the water catchment device including: a cover, a protrusion, and an absorbent element. The protrusion further has an insertion channel for an umbrella to be inserted into and combined with the water catchment device. Furthermore, a catchment is formed between the cover and the protrusion and an absorbent element is mounted in the catchment. The absorbent element can absorb rainwater and retain the rainwater in the catchment. The water catchment device prevents the rainwater from overflowing from the catchment and dripping around. In addition, the cover and the protrusion are made of flexible materials. The absorbent element in the catchment can be dried by pressing the cover. The absorbent element also can be removed from the catchment for drying or replacement whenever needed.

What is claimed is:

 a cover being a hollow container and comprising:
 a bottom, 
 a top opposite to the bottom, and 
 a side part connecting along edges of the bottom and the top; 
   a hollow cylindrical protrusion protruding from the bottom of the cover towards the top of the cover, and comprising:
 a lower end, 
 an upper end opposite to the lower end, and 
 a side wall annularly connecting the lower end and the upper end; and 
   an absorbent element;   
       wherein the bottom of the cover is a closed end; the lower end of the protrusion is sealed and connected to the bottom of the cover; an insertion channel is formed within the side wall of the protrusion and forms an opening at the upper end of the protrusion, and the insertion channel tapers from the upper end of the protrusion towards the lower end of the protrusion; a catchment is formed between the side part of the cover and the side wall of the protrusion, and the absorbent element is selectively disposed in the catchment. 
     
     
         2 . The water catchment device as claimed in  claim 1 , wherein the cover and the protrusion are made of flexible materials, and the absorbent element fills the catchment partially or fully. 
     
     
         3 . The water catchment device as claimed in  claim 2 , wherein the flexible materials are elastoplastic or rubber, and the absorbent element is a sponge.

         5 . The water catchment device as claimed in  claim 2 , wherein an edge around the top comprises an outer rim and the outer rim further has at least one fastener; the water catchment device further has a ring and the ring embeds at least one fixed element; the fastener for fixing to the fixed element, and the ring is selectively fixed on the outer rim. 
     
     
         6 . The water catchment device as claimed in  claim 3 , wherein an edge around the top comprises an outer rim and the outer rim further has at least one fastener; the water catchment device further has a ring and the ring embeds at least one fixed element; the fastener for fixing to the fixed element, and the ring is selectively fixed on the outer rim. 
     
     
         7 . The water catchment device as claimed in  claim 4 , wherein the fastener is a metal ring, and the fixed elements are two magnets. 
     
     
         8 . The water catchment device as claimed in  claim 5 , wherein the fastener is a metal ring, and the fixed elements are two magnets. 
     
     
         9 . The water catchment device as claimed in  claim 6 , wherein the fastener is a metal ring, and the fixed elements are two magnets. 
     
     
         10 . The water catchment device as claimed in  claim 1 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         11 . The water catchment device as claimed in  claim 2 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         12 . The water catchment device as claimed in  claim 3 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         13 . The water catchment device as claimed in  claim 4 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         14 . The water catchment device as claimed in  claim 5 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         15 . The water catchment device as claimed in  claim 6 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         16 . The water catchment device as claimed in  claim 7 , wherein the thickness of the side wall is proportionally decreased from the lower end to the upper end. 
     
     
         17 . The water catchment device as claimed in  claim 1 , wherein an outer face of the side part of the cover further comprises at least one hand-grip portion; the hand-grip portion is a recess. 
     
     
         18 . The water catchment device as claimed in  claim 2 , wherein an outer face of the side part of the cover further comprises at least one hand-grip portion; the hand-grip portion is a recess.
