Support device for chairs set outdoors, in particular on grounds covered with grass

Abstract

There is provided a support device comprising shaped bodies ( 5 ) suitable for engagement with bottom ends ( 2 a, 3 a ) of chairs ( 1 ), each of which has a coupling axis ( 6 ), a coupling cavity ( 7 ) extending along the coupling axis ( 6 ) and insertable on said bottom ends ( 2 a, 3 a ) by pressure and in a removable manner, and a support face ( 8 ) expanded in a direction radial to the coupling axis ( 6 ), which face can be directly put in contact with the ground and rest thereon and which is provided with openings ( 10 ) to break the continuity of the ground-contact surface, and indentations ( 11 ) to avoid interferences when the chairs are stacked up.

1 . A support device for chairs set outdoors, in particular on grounds covered with grass, comprising a plurality of shaped bodies suitable for engagement with the bottom ends of said chairs and each having a coupling axis, a coupling cavity extending along said coupling axis and insertable on one of said bottom ends by pressure and in a removable manner, and a support face expanded in a direction radial to said coupling axis, which support face can be directly put in contact with the ground and rest thereon.  
     
     
         2 . The device as claimed in  claim 1 , wherein said support face has openings adapted to break the ground-contact continuity of said support face.  
     
     
         3 . The device as claimed in  claim 2 , wherein said support face has an outer edge, said openings being formed between said outer edge and coupling axis.  
     
     
         4 . The device as claimed in  claim 3 , wherein an edge wall is provided to make said outer edge stiffer.  
     
     
         5 . The device as claimed in  claim 1 , wherein said support face is substantially shaped like a sector of a circle.  
     
     
         6 . The device as claimed in  claim 1 , wherein said coupling axis is located at an eccentric position with respect to said support face, to avoid interferences when said chairs are stacked up.  
     
     
         7 . The device as claimed in  claim 6 , wherein each said shaped body has a side indentation.  
     
     
         8 . The device as claimed in  claim 1 , wherein each of said shaped bodies comprises a tube internally defining said coupling cavity, and a bottom plate integral with and lying across an end of said tube and defining said support face.  
     
     
         9 . The device as claimed in  claim 8 , wherein said bottom plate has a vent hole at said tube.  
     
     
         10 . The device as claimed in  claim 8 , wherein union tabs extending between said tube and bottom plate are provided.  
     
     
         11 . The device as claimed in  claim 8 , wherein each said shaped body comprises a side indentation confined by said union tabs, said side indentation avoiding interferences when said chairs are stacked up.  
     
     
         12 . The device as claimed in  claim 8 , wherein said tube internally has flexible ribs adapted to enable insertion by pressure of said bottom ends of varying sizes.  
     
     
         13 . The device as claimed in  claim 5 , wherein at least one union element of a size matching that of one said bottom end is provided, which union element is insertable by pressure in said tube.
