Description
SPECIFICATION OF INVENTION
SPECIFICATION-~OFw IION "WATER SUPPLY ELBOW WITHIN A PLASTIC HOUSING COMPRISING
THREE OR MORE PARTS,CONNECTABLE TO PLASTIC CONDUCTORS WITH
A PLASTIC SPIRAL COVERING OF VARYING DIAMETERS" THE BACKGROUND OF THE INVENTION The present invention relates to the field of the art of connecting fittings in water supply networks in general and in particular to the field of connecting fittings suitable for flexible plastic conductors of water supply networks and hydraulic installations in general.
The broad circulation of flexible plastic conductors for hydraulic installations in water supply networks and in central heating and air-conditioning networks as well,has created the need for the development of new connecting
fittings of the said conductors to the conventional commercially available water taps or radiator valves.The coating of the said plastic conductors with another spiral type covering conductor is necessary,so as to enable when required replacement of a portion of the plastic conductor
which presents a malfunction with another new portion of plastic conductor,capable of passing through the same permanently installed spiral-type covering conductor.In this way repair or replacement of parts in the network becomes possible without costly repair work.
It was henceforth necessary to produce couplings, elbows,etc.by means of which one would be able to connect the conventional water supply,radiator valves,etc.to the shorter diameters of flexible plastic conductors.
In order to ensure the inspection and replacement of portions of the flexible plastic conductors which are contained within the spiral type covering conductors,it became necessary to mount the said couplings, elbows,etc.within an independent plastic housing,where
this housing is built into the wall with a free end left for the connection to the metallic tap,valve,etc.The metallic couplings,elbows,etc.are sufficiently protected from corrosion,enclosed within the said plastic housing.
By way of example such a plastic housing has developed
in order to house a metallic water supply elbow.The practical experience of such plastic housings of water supply elbows comprising a single solid or a couple of pieces has presented certain disadvantages,relating to the facility of performing the necessary connections on the one hand to the flexible plastic conductor with the spiral covering and on the other hand to the metallic water tap or valve.The process of disconnecting,if necessary,is even more difficult.A disadvantage of the above plastic housings for water supply elbows of the prior art is that,
because of their construction in one single or two pieses, allow only for the connection and usage with a certain maximum diameter of the spiral covering conductor and this necessitates the provision of plastic housings of different dimensions to cover for spiral coverings of different diameters.
Furthermore, in a two-piece housing,one piece is
conventionally pressed against the other in order to afford their connection. As a result, the cost of manufacturing is higher because such a connecting process involves materials with a desired increased elasticity and it further involves restricted manufacturing tolerances.Furthermore,such a fitting process of pressing one piece of the plastic housing against the other,results in the assemblying and most particularly the dismantling of the housing becoming difficult because of the relatively high stresses developing, which are difficult
to handle manually.Such a process does further result to noise.
Another disadvantage of such plastic housings for metallic water supply elbows of the prior art relates to the dimensions and in particular the internal length and
diameter within which the water supply albow moves and is pulled outwards when it is required to change a portion of the flexible conductor.
As time goes by,the plastic conductor generally suffers from a hardening process leading to a respective
loss of flexibility.The plastic conductor may furthermore develop serpentine fluctuations, resulting to further difficulties in its smooth pulling out.It is for the above stated reasons that it is of special importance to facilitate movement of both the metallic water supply elbow and the plastic conductor by providing the maximum possible internal dimensions of length and diameter and by freeing the interior of the housing from ribs and other formations that may obstruct such movement.
An object of the present invention is to efficiently overcome the above disadvantages and drawbacks of the prior art,providing a plastic housing for a water supply elbow, comprising three or more parts,which is thereby suitable for connection to plastic conductors with a plastic spiral covering of varying diameters,which is of very simple and economical construction,substantially facilitating the process of assembly and dismantiling of all kinds of water
supply elbows,subjectable to minimal operational stresses and thereby presenting a high strength and long service life.
Another object of the present invention is to provide the metallic water supply elbow with changeable
fitting accessories by means of which it may be fitted to flexible plastic conductors,so that it may be easy to change defective fitting accessories when necessary, as well as to use the same main body of the metallic water supply elbow with flexible plastic conductors of varying diameters.
These and other objects,characteristics and advantages of the proposed water supply elbow with a plastic housing comprising three or more parts,connectable to plastic conductors with a spiral covering of varying diameters will become apparent in the following analytical description of the invention.

ANALYTICAL DESCRIPTION OF THE INVENTION
Referring now to the accompanying drawings,we will describe certain illustrative,preferred embodiments of the invention.
In accordance to a preferred embodiment of the
invention,the plastic housing within which seats the metallic water supply elbow,being connected to the selected flexible plastic conductor of hydraulic installations .. generally has a cylindrical shape and comprises two semi-cylindrical parts,nanely one portion
basement 1 and one corresponding covering portion 2.The basement 1 and the covering 2 when assembled provide the generally cylindrical overall appearance of the housing.A first characteristic of such a housing is that the assemblying process is effected easily,without creating any noise and without any special effort.The basement 1 extends to an upper semicircular portion with an internal threading lla,which extends normally to the generally longitudinal semicircular body of the basement l,whereas downwards the basement 1 extends to a semi-circle with an internally shaped recession 17a.The covering 2 on the other hand extends upwards to a semi-circular portion with an internal
threading llb,also provided normally in the extension of the generally longitudinal semi-cylindrical body of the covering 2.The fitting of the covering 2 onto the basement 1 is made by merely bringing into contact and mutually sliding of a couple of points of the vertical lip sections la and lb of the basement 1 to a corresponding couple of points of the vertical lip sections 2a and 2b of the covering 2,whereby the semi-cylindrical surface of the basement 1 fully seats onto the corresponding semicylindrical surface of the covering 2.
Following the assemblying of the covering 2 onto the basement 1 of the plastic housing,the introduction of the metallic water supply elbow and its connection to the flexible plastic conductor 15 with the plastic spiral covering 16,the upper,now complete circular upper surface
with the internal threading lla,b of the housing, is covered by bolting the plastic ring 9 with the corresponding external threading 11.In order to ensure strength in the tightening and eventual stabilizing with the plastic ring 9,the upper semi-circular ending with the internal threading lIb of covering 2 extends to a semicircular or larger than a semicircle or complete circular annulus 22,which following the assemblying of the covering 2 onto the basement 1 of the housing surrounds the upper semicircular ending with the internal threading lla of the basement 1.The upper end of the main body 4 of the metallic water supply elbow extends through the central opening of the ring 9 and is provided
with an internal threading 13, suitable for connection to a commercially available tap or valve accessory.
Furthermore,the ring 9 is internally formed so as to comprise a circumferential recession 10baby means of which ring 9 fits onto a corresponding circumferential recession 10b, at the upper end of the main body 4 of the water supply elbow.Finally the ring 9 is provided with a series of circumferential, preferably circular openings-holes 12,whereby via a special metallic key 23 depicted in Fig. 15 with two side -members 24,introducable to any antidiametrically arranged couple of openings-holes 12,a clockwise or counterclockwise torque is exerted in order to screw or unscrew the plastic ring 9 and fixedly mount or remove the metallic water supply elbow.The abovementioned openings-holes 12 of ring 9 are preferably of circular or square or other desired shape,whereas the screw-driving ends of side members 24 of key 23 have a corresponding form.
The bottom semicircular end bases of the generally semicylindrical portions of the basement 1 and the covering 2 of the plastic housing are provided with an internal
semicircular recession 17a and 17b respectiveiy,whereby the end portion 3 of the plastic housing fits within the thereby formed circular ending with the internal circular opening 17a,b of the assembled plastic housing.
Following its stabilization within the above mentioned opening,the end portion 3 subsequently converges to a longitudinal cylindrical portion of a smaller diameter
corresponding to the diameter of the spiral covering 16 of the flexible plastic conductor 15.Thus, an end portion 3 with a bottom cylindrical ending jf a diameter corresponding to the diameter of the spiral covering employed,may be alternatively used with the same plastic housing.The semicircular bottom extensions of covering 2 and basement 1 are provided with a pair of antidiametrically arranged side flanges 19a and 19b respectively,which are perforated with concentric corresponding holes 18a and 18b.The eventual bottom assemblying of the two portions 1 and 2 of the
plastic housing,following the fitting of the third part 3 within the circular formed recession 17a,b,is implemented by bolting the two pieces together with the bolts 18.
A characteristic feature of the proposed plastic housing is the exploitation of the maximum - possibly
available by the thickness of the walls whereat it is inbuilt - dimensions and thereby free space for the movement on the one hand of the metallic elbow and on the other hand of the plastic conductor which has to be pulled out.The abovementioned free space is fully free from ribs and other formations which could possibly obstruct movement and has a preferred diameter ranging from 34-40 mm and a preferred length of the order of 45-55mm,such length being measured from the end of the formation-seat 21 whereupon the metallic water supply elbow is fitted onto the basement 1 up to the point,where the contraction of diameter starts for the reception of the spiral covering.A preferred industrial
model of the abovementioned plastic housing has been made with an internal diameter of 38 mm and a length of 50mm,as measured from the end of the formation-seat 21 up to the point of contraction of the diameter to receive the spiral covering.
In accordance to an alternative embodiment of the invention as depicted in Fig. 14,the end portion 3 of the plastic housing is also provided with a pair of antidiametrically arranged side flanges 19e onto its upper ending,provided with central holes 18c,whereby all three portions 1,2 and 3 are joined together via the bolts 18.
The metallic water supply elbow is preferably made from brass,by way of example in accordance to DIN 17660,and as shown in the accompanying drawings comprises a main body 4,a connection accessory 6 with a tightness ring 7 seated onto a circumferential recession 14 of the upper part of the connection fitting 6,a metallic biconical ring 5 and a tightening nut 8 by means of which the main body 4 of the water supply elbow is connected to the flexible plastic conductor 15.
A characteristic feature of the above described water supply elbow is the independent provision of the connection accessory 6,which allows for the reception of plastic conductors of varying diameters in the same main body 4 or the water supply elbow.
It must hereby be noted that the description of the present invention was made by reference to merely illustrative embodiments and is not limited hereby.
Thus any change or amendment relating to the size, dimensions,shape,materials and accessories used in the construction and- assemblying process,variety of colours,etc.,as long as they do not comprise a new inventive step and do not contribute towards technical development of the state of the art are hereby considered to be part of the scope and the aims of the present invention.
