LATEST IS APPLIED AGAINST THE CORRESPONDING END OF THE SAID RING.

Description

- i- 2576939 The present invention relates to a device

  for fixing an aerator spray in the spout of a tap.

  It is known that in order to obtain, at the outlet of the spout of a tap, a relatively directional jet, it is necessary to fix in said spout an aerating jet breaker hereinafter called a nebulizer.

  In the current state of the art, nebulis are known.

  sisters in the form of a cylindrical housing, provided with slots, having a shoulder and a peripheral border at one end and containing several grids

  arranged substantially in straight sections of said box

  tier. These nebulizers are fixed using a shouldered nut

  screwed onto the end of the spout.

  Besides the fact that these nuts made of chrome-plated brass

  are relatively expensive, experience has shown that

  sound of lime deposits, disassembly of this nut to

  changing the nebulizer was sometimes very difficult.

  Experience has also shown that on a new valve the disassembly of the nut was very easy and the nebulizer

  was therefore not immune to malicious acts.

  It should also be noted that the standards require that the

  water jet is directed in a predetermined direction.

  As the usual nebulizers are fixed relative to the taps, this condition can only be fulfilled if the main axes of the tap (that of the body and that of the spout) form between them and in cooperation with the wall on which the tap is fixed, predetermined angles. This requirement therefore leaves manufacturers little leeway with regard to aesthetic creation. The appearance of a tap, however, is an important factor that determines the choice

buyers.

  The present invention, which remedies these drawbacks,

  is remarkable in that the nebulizer holding member

  its consists of an elastically deformable ring which is placed in the spout and whose locking in this

  the latter is ensured by the introduction of the nebulizer into the

- 2 - 2576939

  said ring, the latter comprising means for opposing

  to the axial displacement of said nebulizer.

  For this purpose, the spout of the tap has a spherical cavity

  risk with constricted opening in which one engages, by elastic deformation, the aforementioned ring whose dimension of the internal diameter is intended to receive the nebulizer, the peripheral edge of the latter coming to take, bearing against the end of the ring on which it is maintained

  by elastic deformation of locking members.

  The present invention will be better understood from the description

  tion which follows made with reference to the accompanying drawing by way of indicative example only, in which: Figure 1 is a perspective view of a conventional nebulizer; Figure 2 is a perspective view of the fixing ring according to the invention; Figure 3 is a sectional view showing the attachment of the nebulizer in the ring placed in the spout of a tap; Figure 4 is a view similar to that 3 showing the device in the operating position after rotation of

  I80 of the ring-nebulizer assembly.

  Referring to Figure 1, we see that the nebulizer de-

  signed by the reference l, is constituted by a cylindrical case

  that presenting towards one end a part of larger

  diameter 2 ending with a peripheral border 3.

  In the case are arranged grids such as those 4 which appear in the drawing. The housing also has, on its part 5 of smaller diameter than that of part 2, air inlet openings 6. In the use position, the water flows through the nebulizer in the direction of

arrow F1 (Figure 1).

  According to the invention, a ring, made of an elastically deformable material, is used to fix the nebulizer 1

  in the spout 7 of a tap. This ring, one embodiment of which

  tion appears in Figure 2 of the drawing, is designated by the

general reference 8.

  The nozzle 7 to receive the nebulizer 1 has a

-3

  quickly 9 spherical, the orifice 10 of which is constricted.

  According to one embodiment, the ring 8 has two separate parts 11 and 12 separated by an annular groove 13. The part 11 forms a bead whose diameter is

  slightly higher than that of cavity 9.

  Part 12 forms an externally formed skirt

  by a spherical surface whose radius is slightly less

  laughing at that of the cavity 9. The diameter of the ring 8, measured at its end opposite to the bead 11, is less

  the diameter of the IO orifice of the spout.

  In this way, it is possible to engage the ring 8 in the spout by its part 12 which behaves like

an introductory corner.

  By pushing ring 8 along arrow F2, it is deformed

  me and we make it enter the spout so that it

  occupies the position shown in FIG. 3.

  The inner diameter of the ring is substantially equal to that of part 2 of the nebulizer. In this way, by engaging the nebulizer in the ring 8, as shown on

  in FIG. 3, said ring is locked in the spout 7.

  Naturally; means are provided so that the

  the nebulizer 1 in the ring 8 determines the locking

  axial ge of said nebulizer relative to said ring.

  When this result is obtained; we finish fixing the nebulizer by rotating the ring-nebulizer assembly

  from I80 to bring said assembly into the position shown

shown in Figure 4.

  To adjust the orientation of the jet, simply rotate the ring-nebulizer assembly to bring the jet into

the desired position.

  It appears from the above explanations and from the examination

  Figures 3 and 4 show that the nebulizer is practically inviolate.

  lable. According to a mode of immobilization of the nebulizer relative to the ring, the latter has axial lugs 14, elastically deformable, forming towards the center of the ring - 4 - and in combination with the end of the latter notches coming to take support on the periphery of the border 3

of the nebulizer.

  To favor the introduction of the border 3 into the notches 15, the faces of the tabs 14 located towards the center of the

  ring 8 widens notches towards the end of said legs.

  Of course, the present invention is not limited to the embodiment described and shown but extends, to

  contrary, to all variants of shapes and dimensions.
