Definitions
- the present invention relates to a device for positioning a profiled aerator body with respect to a support, in a range of flow of the aerator, and an aerator provided with such a positioning device.
- Document WO 2006/125915 describes an aerator with adjustment of orientation and flow rate obtained by rotation of a profiled body.
- This aerator uses the effect known as the "Coanda effect", and it essentially comprises a profiled body mounted in the center of a duct delimiting a spherical segment against which can rotate a ring fixed to the profiled body. In this way, the profiled body can rotate in all directions with a ball-and-socket motion. In addition, it can also adjust the flow of the aerator by displacement relative to the ring to one end or the other of the conduit.
- the invention relates to this displacement of the profiled body relative to the ring towards one end or the other of the conduit.
- the shaped body when set in a position, does not deviate from it so that a setting chosen by a user is retained. It is also desirable that, at the ends of its stroke, the profiled body is held in a relatively firm manner, in the maximum open position and / or in the closed position.
- the invention relates to a particular implementation of an O-ring or equivalent member held by one of the two components movable relative to each other and sliding on the other of these components.
- the invention relates to a device for positioning an aerator profiled body relative to a support, over a range of displacement corresponding to a range of flow of the aerator;
- the body profile has a cylindrical member with an axis parallel to the direction of movement of the body relative to the support
- the support has a cylindrical housing of complementary section to that of the cylindrical member of the body
- the device further comprises an O-ring arranged between the cylindrical member of the profiled body and the cylindrical housing of the support, and held on a first of the components selected from the profiled body and the support, so that it allows a relative displacement of the profiled body and the support by sliding the O-ring on the second of the components selected from the profiled body and the support.
- the O-ring is held on the support.
- the cylindrical member of the profiled body has a groove on at least part of its periphery, at a position corresponding to the position of the O-ring when the cylindrical member is at one end of the range of displacement of the shaped body. relative to the support. For example, it has a groove at both ends of the displacement range.
- the cylindrical member of the profiled body has a section comprising a core and at least one wing
- the support has a tube shape having at least one longitudinal channel for housing the wing, the thickness tube being smaller than the radial dimension of the wing.
- the support comprises an O-ring holding device which comprises a localized recess of the channel in its part farthest from the center of the tube, the dimension of the recess in the direction of the axis of displacement being order of magnitude of the width of the O-ring.
- the support has three channels and the profiled body has three wings.
- the groove at least of the cylindrical member of the profiled body is formed solely in the wing.
- the support is connected by arms to a ring shaped spherical segment.
- the invention also relates to an airflow orientation and flow control aerator, of the type which comprises an airflow duct having a sectional chamber of which a portion of the interior surface forms a segment.
- a profiled body the greater part of which is arranged in the chamber of the duct and has a gradually increasing and then progressively decreasing section, and a ring cooperating with the duct and with the profiled member so that it supports the profiled body in the conduit allowing movement of the profiled body relative to the conduit, the ring having an outer surface forming a sphere portion of the same radius substantially as the spherical segment of the chamber;
- the profiled body is mounted on the ring by a positioning device according to one of the preceding paragraphs.
- a first advantage of the device according to the invention is that it allows a continuous adjustment and thus ensures the maintenance of the profiled body at any chosen position.
- this device has the advantage of giving a tactile effect to the ends of the range of displacement of the profiled body, so that the user is warned that the profiled body has reached an end of this range.
- the device is inexpensive because it is made entirely by plastic injection, and because the establishment of the O-ring is easy, unlike the case where an O-ring is housed in an inner groove d 'a tube.
- the terms "cylinder” and “cylindrical” refer to a surface that is generated by a straight line that moves parallel to itself, based on a closed curve and whose sections by parallel planes are equal.
- FIG. 1 is a sectional view of a profiled body and a part of its support, in an aerator; and
- Figure 2 is a perspective view of the central portion of the support of the shaped body and an O-ring.
- FIG. 1 shows a support 10 and a profiled body 12.
- the support 10 comprises a tube 14 having on the outside three projections 16 allowing the formation, inside the tube 14, of three longitudinal channels 18.
- the tube 14 is integral with three arms 22 which, on the outside, are fixed to a ring in the form of a spherical segment which cooperates with an aerator duct, as described in the aforementioned document.
- a groove 26 formed in the projections 16, but not in the tube 14, is deep enough to reach the channels 18, as indicated by the opening 20 of Figure 2.
- An O-ring 24, described in more detail in the following, is housed in the groove 26.
- the profiled body 12 comprises a profiled skirt 28 which has slots 29 for the passage of the arms 22 of the support 10.
- the profiled body is integral with a cylindrical member 30 comprising an inner tube whose outer section is complementary to the support section .
- the cylindrical member 30 of the profiled body has a tube portion, radius corresponding to the inner radius of the tube 14, and wings 34 which correspond to the channels 18 and protrude through the openings 20 formed in the support. Accordingly, when the O-ring 24 is placed in the groove 26 of the projections 16 and on the tube 14, parts of the O-ring come into contact with the outer ends of the flanges 32 of the cylindrical member of the profiled body. Thus, in this embodiment, the O-ring 24 is in contact with the cylindrical member at the ends of the wings.
- FIG. 1 shows the position of the profiled body 12 on the support
- a groove 34 has been formed in the flanges 32 of the cylindrical member of the profiled body 12 so that the O-ring 24 can cooperate more intimately with the cylindrical member of the profiled body 12.
- the O-ring 24 is elastic a pulling force applied to the profiled body 12, to the right in FIG. 1, widens the O-ring 24 along the inclined wall of the notch 34, so that, between the end position shown in FIG. 1 and the other end position corresponding to the other groove 36 of the wings of the cylindrical member, the O-ring is constantly in contact with the outer surface of the wings 32 on which it exerts a clamping force, and therefore of friction.
- the profiled body 12 retains the position at which the user has released it, between the positions determined by the end grooves.
- end grooves are not essential.
- positioning can be achieved by simply sliding without any groove, or with a groove at one end.
- the cylindrical member of the profiled body 12 has three wings which are housed in three channels 18 of the support. It suffices according to the invention that there is a wing and a channel. However, it is preferable that several wings and several channels are distributed regularly around the periphery of the components for reasons of balance of forces.
- the O-ring 24 may be formed of a one-piece elastomeric seal.
- it can have other forms.
- it may consist of a sheathed spring or pads connected by springs, a pad being disposed at the location of each wing.
- the slots 29 of the profiled body 12 have a length adapted to the range of displacement of the profiled body 12 relative to the support 10. It is also possible that these slots 29 open at the rear of the profiled body.
- the shaped body and the support which includes not only the central part and the arms 22, but also the outer ring-shaped spherical segment of the aerator, can be each formed by injection molding. Their assembly is extremely simple. Since the O-ring is held over most of its circumference by the support, it is possible to mount it on the tube 14 before introducing the cylindrical member 30 of the profiled body 12.
