Description
VARIABLE-CONFIGURATION HAIR DRYER NOZZLE
SubLect of the invention The present invention relates to a hair dryer nozzle whose shape can be modified to deliver either an essentially cylindrical stream of air, that is with a circular cross section, or a stream of air in the form of a relatively broad flat lamina.
Technological background of the invention Electric hair dryers are designed to produce a stream of air which is heated by an electric resistance and is delivered by the hair dryer which is fitted with a fan for this purpose.
The very design of the hair dryer, in particular its cylindrical circular-section geometry which must house a rotary fan, gives the stream of air a circular cross section.
In certain cases, however, users want a relatively broad and flat lamina of air.
It is therefore usual practice to fit a nozzle on the outlet end where the stream of air is produced. The nozzle ends in a flattened outlet generally in the form of an elongated rectangle, in order to create a broad and flat lamina of air.
A nozzle of this kind can be fitted permanently to the outlet opening of the hair dryer, but it is usually detachable.
In the case of a detachable nozzle, the user may mislay it, or at any rate has the nuisance of looking after an extra component which is sometimes difficult to store.
While the hair dryer is in use, the circular stream and the broad flat stream are found to be alternately necessary and oblige the user to remove and replace the nozzle. This quickly becomes a nuisance, especially as it is hot.
The prior art includes a number of teachings regarding the configurations of air flow in the hair dryers. In particular, French document FR-A-2 640 857 provides a nozzle device made of a flexible material. A reversible bending of the nozzle is controlled by a ring whose rotation causes, by activating an internal mechanism, the change from a cylindrical configuration to a flat and oblong configuration, so as to create a laminar air flow.

A reversible bending of the nozzle is controlled by a ring whose rotation causes, by activating an internal mechanism, the change from a cylindrical configuration to a flat and oblong configuration, so as to create a laminar air flow.
Objects of the invention The object of the present invention is to provide a detachable or non-detachable nozzle for a hair dryer that can easily be modified from a first configuration delivering a stream of hot air circular cross section, until a stream of air is produced with an approximately rectangular cross section, that is to say broad and flat.
The term "rectangular" must be understood as including shapes having slightly circular or even oval-like corners or sides. Similarly the term "circular" can be applied to slightly oval shapes.
The drawbacks of the prior art caused by the fact that when the hair dryer is in use, the standard circular stream and the broad flat stream are found to be alternately necessary, which obliges the user to remove and replace the nozzle, which is hot, can in this way be avoided.
More specifically, the obj ect of the invention is to produce a mechanism that can be fitted to or is integral with the hair dryer, in order to make it easy to have a nozzle of variable shape such that it is capable of delivering a circular-sectioned stream of air as well as a broad and flat stream of air.
The invention will be described in greater detail with referenceto certain preferred embodiments illustrated hereinafter in the appended drawings Brief description of the figures Figure 1 shows a perspective view of a nozzle in a first position producing a stream of hot air of circular cross section.
Figure 2 is a view corresponding to Figure 1 in which the nozzle releases a stream of hot air in the form of a broad flat lamina.

Description of a preferred embodiment of the invention The nozzle having the general reference 1 may be an integral part of a hair dryer or a separate item which can be fitted to an existing hair dryer.

Description of a preferred embodiment of the invention The nozzle having the general reference 1 may be an integral part of a hair dryer or a separate item which can be fitted to an existing hair dryer.
The very design of a hair dryer means in principle that it delivers a stream of air of circular cross section.
The nozzle 1 consists of a cylindrical or frustoconical sleeve 3, one end of which is either an integral part of a hair dryer (not shown), or can be fitted to the outlet orifice of a hair dryer.
In one position (Figures 1 and 3), the stream of air released at the outlet of the nozzle is of a practically circular cross section.
For certain applications, however, the user wants a stream of air in the form of a relatively broad flat lamina.
To produce this effect, the sleeve 3 is fitted with two folding wings 5 capable of making a pivoting movement about geometrical axes 7, and with flaps 9 capable of making a pivoting movement about geometrical axes 11 perpendicular, in principle, to the pivot axes 7 of the folding wings 5.
In the position shown in Figures 1 and 3, the flaps 9 are parallel to the axis ofthe stream of air corresponding to the shape of the sleeve 3, and the folding wings S are in. As illustrated, the upper walls Sa of the two folding wings slide under the upper flap and the lower walls Sb of these same folding wings cover the lower flap.
In this configuration, the stream of hot air continues to maintain a circular cross section which is simply divided into three longitudinal slices in the sleeve 3.
The configuration of the sides of the folding wings may of course be adapted to be slightly circular so as to match the general circular shape of the sleeve 3 when folded away.
To bring about the indicated pivoting movement of the folding wings and flaps about their respective axes 7 and 1 1, pivots or any suitable equivalent means may be provided.
In order to modify the configuration of the nozzle, the folding wings 5 can be pivoted about the geometrical axes 7 in such a way as to flatten the outlet orifice until the position shown in Figures 2 and 4 is arrived at.
Simultaneously, the flaps 9 are raised in such a way as to position themselves, by pivoting about the geometrical axes 11, on the inside of the sleeve 3. The initially circular-sectioned stream of air therefore strikes the flaps 9 and is directed towards the axis of the sleeve 3.

As illustrated, the upper walls Sa of the two folding wings slide under the upper flap and the lower walls Sb of these same folding wings cover the lower flap.

Simultaneously, the flaps 9 are raised in such a way as to position themselves, by pivoting about the geometrical axes 11, on the inside of the sleeve 3. The initially circular-sectioned stream of air therefore strikes the flaps 9 and is directed towards the axis of the sleeve 3.
Simultaneously the stream of air can also diverge to the left and right, following the sides of the now open folding wings 5, giving a stream of air which is of a generally rectangular shape as illustrated.
Any appropriate means can be used to bring about this modification.
Springs (not shown) may for example be used to act on the flaps 9 and folding wings 5 to keep them in the position shown in Figures 2 and 4. When a force is applied, for example with the aid of a ring (not shown) whose diameter is slightly greater than that of the sleeve 3 and which is slid so as to cover the folding wings 5 progressively from the rear to the front, it becomes possible, against the force of the spring, to push the folding wings towards the position shown in Figures 1 and 3. Simultaneously the flaps 9 can be brought into line with the axis of the sleeve 3.
Other means may of course be used.
There is no difficulty in designing the shape of the flaps to perform the desired function, which is to position themselves on the inside of the sleeve and deflect virtually all the air.
The folding wings can also easily be folded, with practically no interference with the movement of the flaps 9.
A slight fillet may be provided, either on the folding wings (the extremities of the upper face or lower face) or on the flaps if necessary.
In practice, it is found that the modification occurs very easily without excessive friction and without significant loss of cross-sectional opening for the passage of the stream of air, when switching from the position in Figure 1 to that in Figure 3. The folding side wings can, if of appropriate dimensions, maintain a reasonable cross section for the air stream when flattened, which corresponds, in this case, to about two thirds of the circular cross section.
