Near the spigot (5) are provided two bearing bushes (6) spaced from one another whereof in each case a first part rests firmly on a rotating part and a second part is spread out to form spring segments (8) which are supported on the other rotating part. <IMAGE>
Description
SPECIFICATION
Mounting for pipe fittings
This invention relates to pipe fittings and particularly to a swivel mounting for a swivel discharge arm on sanitary pipe fittings.
Sanitary pipe fittings with swivel discharge arms are, for example, provided for double washbasins to provide both washbasins with fresh water from one tap fitting or also for washbasins to increase scope of movement for the user by means of an optionally swivelling discharge arm.
Swivel discharge arms are known where a cylindrical spigot is rotatably located in a hole in the tap fitting. In order to guarantee swivelling ability over a long period of use it is necessary to mount the spigot with relatively generous play in the pipe fitting as a precaution for example against harmful mineral precipitation from the water. As a result however the location of the discharge arm is unsatisfactory, i.e. the discharge arm "rattles" or wobbles on the sanitary pipe fitting. In addition, as a result of unsatisfactory mounting, premature wear of the 0 ring fitted as a sealing agent takes place. To remedy these disadvantages it has already been suggested that two 0 rings be fitted side by side on the pivot pin.Round cross section sealing rings of soft elastic material are too yielding however and cannot guarantee accurate long term location of the discharge device in the pipe fitting.
The principle object of the invention is therefore to provide a simple swivel mounting of the discharge which is almost free from play.
According to the invention in its broadest aspect there is provided a swivel mounting for a swivel discharge arm on sanitary pipe fittings wherein the discharge arm is located by means of a cylindrical spigot in a mounting hole characterized in that near the spigot are provided two bearing bushes spaced from one another whereof in each case a first part rests firmly on a rotating part and a second part is spread out to form spring segments which are supported on the other rotating part.
The advantages achieved with the invention are mainly derived from the fact that, through the fitting of accurately sized bearing bushes, preferably made of plastics (as plastics in addition to possessing low friction properties are also particularly insensitive to mineral precipitation from water), it is possible to reduce to a minimum the considerable play of the discharge arm mounting which was previously necessary. It is án advantage for the bearing bushes to be made from plastics by the injection moulding method. In addition, 0 ring wear is reduced to a minimum by the precision swivel mounting and sealing against leakage is ensured over a long period of use. A second 0 ring is no longer necessary.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which~ Figure 1 shows a sanitary tap fitting with a swivel-mounted discharge arm partially sectioned; and
Figure 2a is a sectional elevation on the line Il-lI of Figure 2b.
Figure 1 shows a sanitary pipe fitting 1 for washbasins etc. In the discharge area of sanitary
pipe fitting 1 is fitted a brass bush 40 with a
mounting hole 4. In mounting hole 4 a discharge arm 2 bearing discharge nozzle 3 is swivel
mounted with a spigot pin 5. For axial retention, a circlip 42 locates in an annular groove 51 of
suitable depth in spigot pin 5. The outside diameter of the circlip in uncompressed form is
somewhat greater than the diameter of mounting
hole 4 of brass bush 40. On insertion of spigot pin
5 the circlip 42 is initially compressed by the wall
of mounting hole 4 and subsequently snaps into
position in an annular groove 41 to provide axial
retention.Swivel mounting of spigot pin 5 in
mounting hole 4 of sanitary pipe fitting 1 is
effected by two bearing bushes 6 made from
extremely low friction wear resistant plastics
material fitted at a distance from one another in
grooves 7 on spigot pin 5. As shown particularly in
Figure 2, bearing bush 6 consists of a tubular
section which is provided with a continuous axial
slot 9 for ease of fitting. The tubular section is formed by a cylindrical shell 11 which is of
enlarged diameter at one end. In the enlarged
area, shell 11, in addition to axial slot 9, is sub
divided into spring segments 8 by a number of
longitudinal slots 10. The inside diameter 12 of
bearing bush 6 is such that it firmly surrounds the
bottom of groove 7. The outside diameter 13 of
spring segments 8 is dimensioned such that they
are sprung against the wall of mounting hole 4.
The discharge arm can be mounted in such a
way that, first of all, circlip 42 is fitted on to spigot
5, this being followed by the two bearing bushes 6
and an 0 ring 15 intended for sealing purposes.
Now spigot 5 can be inserted in mounting hole 4
and pushed down until circlip 42 snaps into place.
The spring segments 8 of bearing bush 6 establish
an elastic fit with the actual diameter of mounting
hole 4 in sanitary pipe fitting 1 and in this way
eliminate the play otherwise necessary. After this
has taken place, discharge arm 2 is ready for use.
For dismantling or withdrawal of discharge arm 2
it will be necessary to exert force commensurate
with the design of circlip 42.
Of course, grooves to accept the bearing
bushes can also be provided in brass bush 40.
Here it would then be necessary for the spring
segments to project into mounting hole 4. This
design is specially recommended for discharge
arms of thin walled tubing.
When selecting the length of bearing bush 6 it
has been found preferable for approximately one
third of the overall length to make rigid contact in
the bottom of a groove and for two thirds of the
overall length to be used for the spring
segments 8.
