Quick connection, and liquid supply system provided therewith

Abstract

A quick connector for connecting a source of fluid to a working element has a body connectable to the fluid source and having an axis, a fitting member connectable to the working element and axially movable relative to the body, and a locking member connected with the body for locking the body and the fitting member with one another in an assembled condition, the fitting member having a part provided with an outer conical surface which is insertable in an inner conical surface of a holder.

1 . A quick connector for connecting a source of fluid to a working element, comprising a body connectable to the fluid source and having an axis; a fitting member connectable to the working element and axially movable relative to said body; and a locking member connected with said body for locking said body and said fitting member with one another in an assembled condition, said fitting member having a part provided with an outer conical surface which is insertable in an inner conical surface of a holder.  
   
   
       2 . A quick connection as defined in  claim 1 , wherein said part having an outer conical surface insertable into an inner conical surface of the holder has an inner opening into which a part of the working element is insertable to be connected with the fitting member.  
   
   
       3 . A quick connection as defined in  claim 1 , wherein said body has at least one radially deflectable tongue provided with a radially inwardly extending projection and a radially outwardly extending projection, said locking member having a radially outwardly projecting flange, said fitting member having a radially inwardly projecting portion, said projections of said body, said flange of said locking member and said portion of said fitting member being formed so that when fluid is supplied through the connection under pressure, said radially inwardly projecting portion of said fitting member applies pressure against said radially inwardly extending projection of said body and deflects radially outwardly said at least one deflectable tongue and therefore displaces radially outwardly said radially outwardly extending projection of said body so that said radially outwardly extending projection of said body abuts against said radially inwardly extending flange of said locking member and thereby locking member can not be displaced in an axial direction; and locking spring arranged between said body and said locking member.  
   
   
       4 . A quick connection as defined in  claim 3 , wherein said fitting member has a groove located axially near said radially outwardly projecting portion and formed so that said radially inwardly extending projection of said body engages in said groove and thereby said locking member locks said body with said fitting member.  
   
   
       5 . A quick connection as defined in  claim 3 , wherein said at least one deflectable tongue has a conical projection.  
   
   
       6 . A liquid supply system, comprising a working element; a quick connection connecting a source of fluid to a working element, and including a body connectable to the fluid source and having an axis; a fitting member connectable to the working element and axially movable relative to said body; and a locking member connected with said body for locking said body and said fitting member with one another in an assembled condition and a holder for holding said quick connection, said fitting member having a part provided with an outer conical surface which is insertable in an inner conical surface of said holder.  
   
   
       7 . A liquid supply system as defined in  claim 6 , wherein said working element is a hand shower.  
   
   
       8 . A liquid supply system as defined in  claim 6 , wherein said body is connectable to a shower hose.
