Water supply elbow within a plastic housing comprising three or more parts, connectable to plastic conductors with a plastic spiral covering of varying diameters
First Claim
1. A plastic housing for a metallic water supply elbow comprising a first basement portion and a second covering portion, said first and second portions forming a housing when assembled of generally cylindrical cross-section, said first and second portions can be separated for the easy introduction or removal of said metallic water supply elbow, with the upper end of said metallic water supply elbow connected to a conventional water tap, radiator valve or other commercially available accessory and the bottom end of the elbow is connected to a flexible plastic conductor having a plastic spiral covering, a third generally cylindrical portion is provided at the bottom end of the housing to allow connection of various diameters of said plastic spiral covering of said conductor to the assembled plastic housing, and a fourth annular connection ring, said annular connection ring is provided with an external thread for threading into an upper circular opening having a corresponding internal thread, said first basement portion and said second covering portion forming when assembled said upper circular opening, said annular connection ring is also provided with an inner circumferential recess which fits onto a corresponding circumferential recess at the upper end of said metallic water supply elbow.

Abstract
The present invention proposes a water supply elbow with a plastic housing, suitable for connections with flexible plastic conductors of hydraulic installations of water supply networks and of central heating and air-conditioning networks with the conventional water taps, radiator valves and other commercially available accessories, where mainly built into the walls and/or laid underneath the floor the abovementioned flexible plastic conductors are covered by an external spiral coating. The basic charactertistics of the proposed water supply elbow with a plastic housing are its manufacturing three or more parts which allow for passing through the end cylindrical portion (3) of spiral coverings of the flexible plastic conductors of varying diameters, the simple and economical construction of the generally semicylindrical basement (1) and the generally semicylindrical covering (2) which is mutually engaged by mere contact, the bottom end provided with an internal recession suitable for fitting the third cylindrical part (3) of the housing via tightening through screwing within the holes (18a,b,c) provided onto side flanges (19a,b,c) either of the two parts (1) and (2) or of all three parts (1), (2) and (3) of the housing.
