Description

"ACCESSORY FOR USE TOGETHERWITH HAIR DRYERS".
The present Invention patent describes an accessory developed especially to be used together with manual type hair dryers, which has the purpose of allowing a better distribution of the air flow among the hair volume during the drying process.
As it is of general knowledge, a wide range of accessories for use with hair dryers is largely known, which are normally parts destined for assembly at the device's air exit end.
Some accessories have the purpose of concentrating the air flow or also to make such flow essentially turbulent or even to produce differentiated flow diffusion under certain conditions.
In the case of drying of dense or voluminous hair, it is normal that professionals helps the drying process through movements with the fingers from the bottom up aiming at thus creating spaces through which the air coming from the hair dryer may enter and thus speeding up the drying process.
This kind of technique thus requires the professional to have both hands permanently busy, i.e. one that holds and operates the dryer and another one that moves the hair during the drying process. In view of this state of the art, it was developed a special type of accessory which allows taking the flow of heated (or not) air to the inside of the hair volume and in an analog.but perfected form reproduces the effect of the movements that the professional makes directly with one of his hands, such as already described.
The accessory here described was developed to be directly coupled to the air exit end of a generic model hair dryer, thus transferring the air flow coining from this device to the interior of the accessory and then directly to the hair to be dried.
The accessory, here dealt with, features a format analog to the human hand, with projections similar to fingers where the air flow exits through the openings that, due to the design of the mentioned projections, deeply enter the center of the volume of the hair to be dried.

Figure 34 illustrates a similar view as depicted in figure 32, however showing a quick rotation movement among the parts, such as indicated by arrow X.
In accordance with what the listed above figures show, the accessory that is the subject matter of this Invention patent comprises a hollow part 1 , preferably obtained in an injected piece of plastic which has a connection terminal 2 that features a format essentially tubular and dimensioned for coupling by locking to the end part of a generic hair dryer model(not illustrated).
The connection terminal 2 is developed in an intermediate chamber 3 from which hollow projections 4 derive that feature a format analog to fingers of a human hand.
The projections 4 (canalize and divide the air flow coming from the dryer and lead such flow to a series of strategically positioned openings 5. The openings 5 are present in both the projections 4 and the body of the intermediate chamber 3. The hollow part that constitutes the present accessory is composed of two distinct sections, one of which, the main section, is indicated by reference IA, that encompasses the connection terminal 2 and the upper side of the intermediate chamber 3 and of the hollow projections 4, while the second section or lower section is indicated by reference IB and defines the lower side of the region of the intermediate chamber 3 and of the hollow projections 4.
The fixation of the lower section IB against the main section IA is made through projections of pins/housing 1C (especially visible in figures IB and 1C), distributed along the hollow projections 4 as well as through a pair of screws ID (visible in figure 3) that connect the lower section IB to the main section IA in the proximity of the connection terminal 2. Still with regard to the connection terminal 2, as can be seen in figures 1 and IA, it has retention components IE that are defined as rubber inserts assembled in the openings IF (visible in figure IA) produced in the wall of the connection terminal 2. The retention components IE have the function of maintaining contact projections in the interior of the side of the connection terminal 2 that touch the end part of the hair dryer when the accessory here dealt with is introduced. Thus, the fixation of the accessory as a whole to the end part of the hair dryer is made by means of direct friction of the retention components IE with the wall of the end part of the dryer. The cut of figure IA allows observing that component IE is assembled in such a way as to be stuck in its respective opening IF.
In the way of its concretization the accessory here dealt with presents a format that reproduces in a technical way, the general format of the human hand where the projections 4 act analogically to fingers. The accessory here presented may be projected in such a way as to incorporate a greater or smaller number of projections 4, as its project is not restricted to the number of five projections, such as illustrated.
Figure 18 depicts, in a schematic form, the form of the air flow circulation (indicated by means of arrow F) in the interior of the accessory where it can be noted that the flow initially passes through the connection terminal 2, then through the intermediate chamber 3 and after that on to the projections 4, where the flow F, already divided between all projections 4 reaches the respective openings 5.
The accessory here dealt with may feature a totally rigid main model (without movable parts), such as demonstrated in figures 1 to 7, whereby also a first variation is foreseen as depicted in figures 8 to 11 where sectors in the form of an accordion 6 are supplied in the very material of which the accessory is manufactured, and such sectors in form of an accordion 6 connect the respective portions of the projections 4 and the movable portions 4A. The construction of the sectors in form of an accordion may be observed better in figure 19 where one of the movable projections 4A may be seen in the schematic cut.
As variation of the sectors in form of an accordion 6 that allow for the mobility of the movable portions 4A, a spherical connection 6A may be used alternatively which is incorporated into the end of the movable portion 4A and which is locked into the fix end of the projection 4.
The sectors in form of an accordion 6, such as depicted in figures 8 to 11 allow that the movable portions 4A may be adjusted in terms of their positioning in relation to the body of the accessory as a whole, thus allowing better adjustment of their positioning, whereby the same effect is obtained by the construction depicted in figure 20 where a spherical connection 6A is foreseen. Within the same concept of the accessory dealt with in the first variation, which is depicted specifically in figures 12 to 17 and where a sector in form of an accordion 7 is incorporated into the region of the connection terminal 2 allowing movement among the main portion of the accessory and the connection terminal 2 that is normally coupled to the end part of a conventional hair dryer (not illustrated).
The three modalities of the accessory here presented (main model, first and second variation) present the same basic constructive concept, i.e. define a hollow component that, assembled onto the end part of a conventional hair dryer, allows the air flow (whether hot or not) to be directed to the projections 4 and from them the flow may then deeply penetrate, even in the middle of dense and voluminous hair. The present accessory also includes two variations that deal with forecasting a control system of air flow and means that allow the change in the axial positioning between the accessory and the hair dryer to which it is coupled. Regarding the provision of means of controlling the flow, the hollow part 1 that constitutes the present accessory may have means of controlling the air flow 8, internally mounted to the diffuser structure, such as can be noted by viewing the figures 25, 26, 27, 28, 29, and 30, said means of controlling the air flow 8 are defined as flexible material strips 9, mounted on trails 10 incorporated in the hollow part structure 1.
Said means of controlling the air flow 8 are projected and mounted in order to be dislocated in any way indicated by arrows X-Y, such as demonstrated in figure 25, thus allowing openings 9A incorporated in the flexible material strips 9, to be aligned or not with openings 5 provided in the hollow part structure 1.
When the openings 9A are aligned with openings 5, it occurs the passage of air flow through them, and in the opposite way, when said openings are not aligned, it occurs the obstruction of air flow.
There is still the possibility of regulating the flow in the extent that the alignment or not of the openings can be established in several intermediate levels. Figure 26 depicts a cut wherein means of controlling the flow were omitted to allow the view of the trails 10 and the openings 5 details incorporated in the hollow part structure 1 that constitutes the present accessory. Figure 27 depicts a similar cut as figure 26, however schematically including the strips that define the means of controlling the air flow 8, and in the figure 27 it is depicted an opening condition for the passage of air flow through the upper portion of the diffuser.such as indicated by arrow A and of closing or obstruction of flow, such as indicated by arrow B, and on the other side the figure 28 illustrates exactly the inverse condition.
Figures 27 and 28 demonstrate that the air flow can be conducted in an alternate manner to the upper and lower portions of the hollow part 1 , thus allowing a greater control of the drying result that will be obtained.
Figures 29 and 30 depict the diffuser in question in its fully unobstructed condition and wherein the air flow can be applied not only by its lower portion, but also by its upper portion, once the openings 5 and 9A are aligned.
The movement for the means of controlling the air flow 8 is obtained in a simple manner by sliding the flexible material strip 9 along the trails 10, result that is obtained through the actuation over projections 11 that leaves the strip 9 and that are exposed from openings 5A incorporated in the hollow part 1 , such as occurring with the openings 5.
Openings 5A exclusively function as mean of dislocation and stroke to the respective projections 1 1 , which can be viewed in figures 23, 24, 25 and 29. Figure 31 illustrates the present accessory within the context in which it is contemplated the provision of means that allow the change of axial position for the accessory as a whole regarding the hair dryer (not shown) . Such change possibility in the position is obtained by the introduction of a connection terminal 2 which includes a rotatably portion 2A, which establishes a link with the integral or fixed portion 2B, being that mounting between both is made through dovetail, where resilient bolts 2C, each with a positioning tooth 2C1 getting in touch with teeth 2B' foreseen in the fixed portion 2B of connection terminal 2.
Mounting between fixed and movable portions of the connection terminal 2 can be better understood through viewing figures 33 and 34.
The connection terminal 2 proposed in this variation is mounted with the dryer using the same means depicted in the original patent, however the rotatably portion 2A (movable in relation to the accessory structure in question), is firmly mounted by dovetail in the hair dryer nozzle (not shown), being rotatably in relation to the fixed portion 2B such as indicated by arrow X of figure 34.
When this rotation occurs, the positioning tooth 2C of resilient bolts 2C exchange space between the teeth 2B' of fixed portion 2B, thus generally altering the positioning of operative portion of accessory, regarding the hair dryer.
The connection terminal 2 depicted in figures 31 to 34 allows the professional operating the dryer to always find the better position to the accessory.
The tooth 2B' are produced in a way that they can establish a diverse range of positions pre- established between the rotatably portion 2A and fixed portion 2B. The resilient bolts 2C are produced integrally to the rostatably portion 2A.
