CROSS REFERENCE APPLICATIONS

This application claims the benefit of German Application No. 20 2013 105 507.7 filed Dec. 4, 2013, which is incorporated herein by reference for all purposes.

BACKGROUND

The present disclosure relates to a hair styling device with two arms that can be adjusted relative to one another in an articulated manner for receiving and styling a strand of hair. Both arms have a facing shaping plate with a shaping surface that makes contact with the hair strand during the hair styling process.

Such hair styling devices are used, for example, for smoothing hair. For this reason they are often also designated as “straighteners”. In the prior art hair styling device the facing shaping surfaces of the shaping plates carried by each arm are designed in a planar manner. As a result of the articulated connection of the two arms the shaping plates can be moved toward and away from one another. In the closed position of the two arms the shaping plates lie against one another with their shaping surfaces. The shaping plates are heated, for example, by PTC heating elements connected to them. A heating of the shaping plates can also be provided by a current of warm air or by a combination of these two heating techniques. The first step in smoothing a strand of hair with such a hair styling device is when a hair strand is laid in the opened device and the hair styling device is subsequently closed. In the closed position of the hair styling device the closing pressure acts on the hair strand inserted between the shaping plates. The hair strand is subsequently drawn through the two heated shaping plates pressing against one another. The hair styling device is moved during this hair styling process. The heat and the shaping pressure bring about the desired smoothing of the hair.

With such a hair styling device, a person may smooth their own hair. In such a use of the hair shaping device the movement of hair styling device does not always take place in a translatory manner but often in a curved path. Because of this, it is often the case that parts of the initially grasped hair strand come out during the hair styling process from the hair styling slot on its side further removed from the articulation of the two arms. The managing handle of such a hair styling device is located on the arms on the side of the shaping plates that is closer to the articulation.

Such hair styling devices can also be used to shape curls or waves because the are designed to have a cross section that is usually approximately semicircular or has a semi-elliptical shape and the heated hair can be would around the outer side of the closed arms. In such a use a straightener is used like a curler rod. The outer side of at least one arm then functions like a shaping body. The previously described, undesired exiting of hair from the shaping slot transversely to the direction of pulling a strand of hair through the hair styling slot occurs more strongly when using such a hair styling device for forming curls or waves.

The foregoing example of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the drawings.

SUMMARY

Starting from this discussed prior art, the present disclosure has the basic problem of further developing an initially cited hair styling device in such a manner that an exiting of hair from the hair styling slot located between the two shaping plates is prevented, or at least hindered.

The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tool and methods which are meant to be exemplary and illustrative, not limiting in scope. In various embodiments, one or more of the above described problems have been reduced or eliminated, while other embodiments are directed to other improvements.

In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

This problem is solved the present disclosure by a generic hair styling device in which a blocking rib is provided adjacent to the shaping surfaces of each of the two shaping plates on their side remote from the pivot axis of the arms and projecting in the direction of the particular other arm and running transversally to the longitudinal extension of the particular arm, The two blocking ribs are arranged offset to one another and adjacent in the closed position of the arms and which run parallel to one another and overlap above a certain height, and which do not extend to the particular other arm in this position of the two arms to one another.

In this hair styling device blocking ribs are provided adjacent to the shaping surfaces, as a result the exiting of hair from the hair styling slot transversally to the direction of drawing a strand of hair through the hair styling slot is effectively hindered or prevented. In this embodiment of a hair styling device each arm carries a blocking rib projecting toward the particular other arm and whose longitudinal extension is arranged transversely to the longitudinal extension of the arm and adjacent to the side of the shaping surfaces of the shaping plates, which side is remote from the pivot axis of the arms. Of course, the blocking ribs can also be arranged adjacent to the shaping plates. Typically, an attempt is made to keep the distance of the blocking ribs from the shaping surfaces as small as possible. The height that the blocking ribs project from the surface of the arm carrying the blocking rib in the direction of the other arm is adjusted in such a manner that in the closed position of the arms they are arranged offset to one another and running parallel to one another and overlapping in their height in one section. Therefore, the minimum height of the blocking ribs is the height that they must have so that the desired overlapping is given in the closed position of the arms. This serves to form a labyrinth for hindering or preventing the exiting of hair on the side of the forming surfaces located transversely to the direction of pulling the hair through. The embodiment of the closed position of the arms also comprises in this connection the closed position itself with a strand of hair inserted between the two shaping plates for the purpose of shaping the hair. However, the height of the blocking ribs is not so high that the blocking ribs of the one arm reach the other arm in the closed position. As a consequence, the closing movement of the arms is not adversely affected by the blocking ribs. In the closed position of the arms there is preferably an air slot with a low width between the sides of the blocking ribs facing one another in the plane of the shaping surface. However, in principle the blocking ribs can also rest on one another but this is not preferred. The slot width between the two blocking ribs in their closed position is sufficiently small so that a tuft of hair cannot readily exit from the hair styling slot during the course of hair styling movement carried out in a customary manner. The slot width is typically between 0.1 and 2.0 mm. This ensures that during the closing of the arms any hair trapped between the blocking ribs due to their offset and overlapping arrangement can be pulled out.

Since during the hair styling process with this hair styling device an unintended exiting of hair from the hair strand originally placed into the hair styling slot is avoided, the result of the hair styling is much more uniform. Typically, an unintended lateral exit of tufts of hair from the hair styling slot is not noticed, which makes the user believe that the entire hair strand originally placed in the hair styling slot had been smoothed.

This concept can be used in hair styling devices of the type under discussion, that is, in particular in so-called straighteners, independently of whether the shaping plates are rigidly held on the particular arm or are mounted in a floating manner. The concept of a floating support of at least one shaping plate used in the framework of these comments denotes a flexible support in a direction at right angles to the extension of the shaping surface of the shaping plate. In the case of such a floating support the shaping plate is held in its initial position by one or more elements that make a return force available. Such a shaping plate can be pressed in counter to the force of the return element or return elements by the admissible amount of the floating support into the arm carrying this shaping plate. The return elements can be of a different nature. For example, one or more return springs can also be provided to this end as well as elastically reacting material, such as, silicone supports or also magnetic return forces. “Floating” also denotes in the framework of these comments a support of such a shaping plate which support is constructed like a whip, as is described in DE 20 2008 016 616 U1. In a preferred embodiment of the hair styling device both shaping plates are mounted in a floating manner.

In the case of a floating support of the at least one shaping plate it is held according to an exemplary embodiment in a shaping plate frame. In the case of such a construction the frame is supported in a floating manner and therefore also the shaping plate held by it. The blocking rib is preferably arranged on the frame in such an exemplary embodiment and therefore follows its support movements. This ensures that even in the case of a shaping plate pressed into the floating support the blocking rib does not reach the other arm. This is naturally also true when the blocking rib is formed on the shaping plate.

The blocking ribs are typically constructed as rigid, non-flexible bodies and comprise a curved crown on the upper side facing the other arm.

The central longitudinal plane of the blocking ribs can be designed to be straight. It is also possible to form the blocking ribs in such a manner that their central longitudinal plane is curved, namely, with a radius of curvature that corresponds to the distance of the central longitudinal plane of a blocking rib from the pivot axis of the two arms.

According to a depicted embodiment of such a hair styling device one of the two arms comprises a hair support on its side carrying the shaping plate. The hair support is arranged at a distance to the shaping surface of the forming plate of this arm in order that the other arm fits in between the hair support and the arm carrying it. The two arms can be adjusted in the manner of scissors in such an exemplary embodiment relative to the shaping plates carried by them. The plane of the shaping surfaces of the shaping plates of the two arms is inclined relative to the movement plane of the arms. This means that the two arms can be adjusted against one another in the plane of the shaping surfaces or at least with a determining vectorial amount located in this plane. To this extent the pivot axis of these arms is not in the plane of the shaping surfaces, as is the case in traditional hair styling devices, but rather at an angle to it, in particular at an angle greater than 70°. In addition, it is provided that one of the two arms carries a hair support. This hair support is at a distance from the side of the arm that carries the shaping plate, namely, so far that the other arm fits in between the hair support and the arm carrying the hair support. The hair support typically extends parallel to and at least over the longitudinal extension of the shaping plate of this arm. Due to the previously described scissor-like adjustability of the two arms of this hair styling device to one another, the arm that does not carry the hair support can be pivoted out of its position of use when it borders with its shaping surface on the shaping surface of the other arm. An ability to pivot is allowed at least to the extent that a hair strand can be placed on the hair support and the side of the arm carrying the hair support, which side is arranged at a distance from the hair support. The hair strand is then supported at two points. If the other, second arm that is pivoted out opposite the first arm carrying the hair support is pivoted back into its position of use, the hair strand located on the previously described support arrangement is drawn in with this arm into the closing hair styling slot. In this process the hair strand lies automatically on the outer side of the arm closing the hair styling slot. If the arms of this hair styling device are closed with the previously drawn-in hair strand, the hair strand is located in the intended support on the outer side of an arm so that a rotation of the hair styling device in order to place the hair to be shaped on the outer side of an arm serving as shaping body is no longer necessary. Consequently, the manipulation is made easier, which is especially noticeable when a person is shaping their own hair and must look into a minor to do so.

An especially advantageous construction is one in which the plane of the shaping surfaces of the shaping plates of the two arms is inclined relative to the movement plane of the arms. According to a preferred embodiment of such a hair styling device the inclination of the shaping surface to the movement plane of the arms is not more than 20°. An arrangement of the planes of the shaping surfaces with a greater angle of inclination has the result that the contact of the hair strand to be shaped on the outer side of the one arm serving as shaping body makes contact only extending over a lesser angular amount. The attempt is typically made to the extent possible to use the outer side of the one arm as a shaping contour for forming curls or waves. It is understood that the outer side of the arm that is not carrying the hair support is either appropriately shaped for the desired shaping or comprises appropriate elements on which, or in which, a hair strand that was previously heated between the shaping plates is drawn over them and brought into the desired shape.

Exemplary embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than limiting. Also, the terminology used herein is for the purpose of description and not of limitation.

The invention is described in the following using exemplary embodiments with reference made to the attached figures, from which other advantages of the invention result. In the figures:

DETAILED DESCRIPTION

A hair styling device 1 conceived as a straightener comprises two arms 2, 3 connected to one another in an articulated manner. The pivot axis of the two arms 2, 3 relative to one another is designated by the reference numeral 4. Each of the two arms 2, 3 carries a shaping plate 5 and 6 on the side facing the other one. The shaping plates 5, 6 comprise a planar shaping surface 7 and 8 on the sides facing one another. The shaping plates 5, 6 are electrically heated, in the exemplary embodiment shown by a PTC element connected on the back side. The pivot axis 4 is located in the plane of the shaping surfaces 7, 8 in the hair styling device.

Each arm 2, 3 carries a blocking rib 9, 10 adjacent to the side of the shaping plates 5, 6 facing away from the pivot axis 4 and therefore adjacent to the two shaping surface 7, 8.

FIG. 2 shows in a schematic sectional view the end section of the arms 2, 3 with the arrangement of the blocking ribs 9, 10 to one another and to the particular shaping plates 5, 6. The shaping plate 5 is held in a shaping plate frame 11. The shaping plate frame 11 itself is supported in a floating manner in the arm 2. The shaping plate frame 11 is supported on its back side on several pressure springs 12 for the floating support of the shaping plate 5. In the exemplary embodiment shown such a pressure spring 12 is present in each corner area of the shaping plate frame 11. The other ones are therefore not visible. The shaping plate frame 11 is held by the pressure springs 12 in its position shown in FIG. 2 as stop position. The shaping plate 5 and therefore the shaping plate frame 11 can be pressed into the arm 2 by a certain amount counter to the force of the return springs 12. The shaping plate 6 is supported analogously in a floating manner on the arm 3.

The blocking rib 9, that is connected to the shaping plate frame 11, is located immediately adjacent to the shaping plate 5. FIG. 2 shows the blocking rib 9 in a transversal side view. The blocking rib 9 extends substantially over the entire width of the shaping plate 7 and of the arm surface 13 carrying the shaping plate frame 11. The blocking rib 9 comprises a crown 14 formed rounded facing the arm 3. The blocking rib 10 is connected in an analogous manner to the shaping plate frame 15 of the arm 3 but with a certain distance to the closure of the shaping plate 6 on this side. This spacing of the blocking rib 10 from the shaping plate 6 serves the purpose that in the closed position of the two arms 2, 3 the two blocking ribs 9, 10, as FIG. 3 shows, are arranged offset relative to one another and therefore overlap over a certain extent of their height. The height of the blocking ribs 9, 10 is dimensioned in such a manner that the overlapping area is advantageously more than 30% of the total height of the blocking ribs 9, 10 but typically even more than 50% of their height in the closed position of the two arms 2, 3. The height of the blocking ribs 9, 10 is provided regarding the overlapping in such a manner that an effective overlapping is given even if a hair strand is inserted between the two shaping surfaces 7, 8 of the two shaping plates 5, 6 and one or both shaping plates 5, 6 is somewhat pressed with their particular shaping plate frames 11 and 15 into the particular arm 2 or 3 against the direction of closing counter to the force of the return springs 12.

The height of the blocking ribs 9, 10 is typically the same height.

The arrangement of the blocking ribs 9, 10 to one another in the exemplary embodiment shown in the figures is provided with an air slot 16 with a small width. The slot width in this exemplary embodiment is approximately 0.3 mm.

The closed position of the two arms 2, 3 shown in FIG. 3 and the arrangement of the blocking ribs 9, 10 to one another brought about as a consequence makes it clear that a blocking labyrinth is made available by this arrangement that effectively avoids a lateral sliding out of hair located between the shaping plates 5, 6 transversely to the direction of pulling along which the hair styling device 1 is moved along for smoothing a hair strand on it. On the other side the height of the blocking ribs 9, 10 is not so great that they extend to the particular other arm and consequently in the closed position shown in FIG. 3 of the two arms 2, 3 do not contact the shaping plate frame 15 or 11 of the particular other arm 3 or 2.

FIG. 4 shows a modification of the exemplary embodiment of the previous figures. The hair styling device 1.1 according to FIGS. 4 and 5 differs from the one of FIGS. 1 to 3 by the design of its blocking ribs 9.1, 10.1. Otherwise, the hair styling device 1.1 is identical to the hair styling device 1. The same structural parts are indicated in it with the same reference numeral supplemented by a “.1”.

The blocking ribs 9.1, 10.1 differ from the blocking ribs 9, 10 of the exemplary embodiment of the FIGS. 1 to 3 by a bend A directed in the direction of the particular adjacent shaping plate 5.1 or 6.1. The bends A of the blocking ribs 9.1, 10.1 serve to reinforce the labyrinth effect in order to prevent a pulling out of hair when using the hair styling device 1.1.

FIG. 5 shows the hair styling device 1.1 in the closed position of its two arms 2.1, 3.1. It becomes clear from a comparison with the related view of the hair styling device 1 of FIG. 3 that the labyrinth through which a pulling out of hair should be prevented is improved by the bends A. The bend A of the blocking rib 9.1, that is closer to the shaping plates 5.1, 6.1, is located at a height between the two arms 2.1. 3.1 such that its side facing the arm 2.1 is offset in the direction of the shaping plate 6.1 of the arm 3.1 relative to the hair styling slot present between the shaping plates 5.1, 6.1. Hair exiting from the hair styling slot is then caught especially effectively by this bend A.

FIG. 6 shows yet another hair styling device 1.2, that corresponds to the hair styling device 1.1. The same structural parts are indicated in this figure with the same reference numeral supplemented by a “.2”. The hair styling device 1.2 differs from the hair styling device 1.1 by the formation of the bend A of its blocking rib 9.2. The latter is inclined somebody in the direction of the shaping plate 6.1 relative to the bend A of the hair forming device 1.1. In the represented arrangement of the blocking ribs 9.2, 10.2 hair exiting out of the hair styling slot between the two shaping plates 5.1, 6.1 is even more effectively kept away from the slot between the end of the bend A and the adjacent shaping plate 6.1.

FIG. 7 shows another exemplary embodiment of a hair styling device 17 that can be used, among other things, as a straightener that is constructed using the principle of the hair styling device of the FIGS. 1 to 3. Therefore, the comments made for the latter also apply to the hair styling device 17. The two arms 18, 19 are also adjustable to one another around the pivot axis 20 in an articulated manner like pliers or shears. FIG. 7 shows the hair styling device with open arms 18, 19. In the hair styling device 17 the shaping plates are not arranged in a vertical alignment with one another regarding the shaping surfaces in distinction to the arrangement of the shaping plates 5, 6 of the hair styling device 1, but rather the shaping plates 21, 22 are inclined as concerns their shaping surfaces relative to the movement path of the arms 18, 19 for opening and closing them, typically at an angle between 10° and 20°. This can be recognized from the course between the plane of the shaping surface of the shaping plate 21 and the course of the pivot axis 20. The shaping plates 21, 22 are supported in the same manner floating on the particular arm 18 and 19, as is described for the shaping plates, 5, 6 for the exemplary embodiment of FIG. 1. Also, a blocking rib 23, 24 is located adjacent to the shaping plates 21, 22 on each end facing the free end of the arms 18, 19. These blocking ribs assume the same function as the blocking ribs 9, 10 of the hair styling device 1. The comments about the blocking ribs 9, 10 of the hair styling device 1 apply in the same manner to the blocking ribs 23, 24 of the hair styling device 17 as regards their arrangement relative to the shaping plates and to one another.

In the hair styling device 17 the arm 19 is V-shaped. The shaping plate 22 is located on the one shank 25 of the V-shaped design. The two shanks 25, 26 of the arm 19 enclose an arm receptacle 27 for receiving the arm 18 for a hair styling. The arm 18 is constructed and dimensioned in a complementary manner for this purpose as regards its cross-sectional geometry in that in the closed position of the two arms 18, 19 the shaping plates 21, 22 rest on one another. The inside of the shank 26 and the outside of the arm 18 on its side opposite the shaping plate 21 carry hair guide structures. The upper termination 28 of the shank 26 serves in the hair styling device 17 as a hair support. Before the closing of the two arms 18, 19 the hair strand to be shaped lies on the upper terminations of both shanks 25, 26 and therefore bridges the arm receptacle 27. During the closing of the two arms 18, 19 the bottom of the arm 18 engages into the arm receptacle 27 so that the hair strand is guided onto the shaping surfaces of the two shaping plates 21, 22, rests there and is guided out of the arm receptacle 27 again on the other side of the arm 18.

The hair styling device 17 is used either as a straightener for smoothing hair or as a curler rod for forming a curl or wave depending on the direction of movement with which the hair styling device 17 is drawn on the grasped hair strand. In the first instance the hair styling device 17 is moved in such a manner opposite the hair strand to be shaped that the hair heated by the shaping plates 21, 22 exits at the upper termination of the shank 25. In the other instance the hair strand is drawn in on this side at first between the shaping plates 21, 22 in order to heat the hair strand and is drawn around the lower termination of the arm 18 and the outer side of the arm 18 (not visible in FIG. 7). The curl or the wave is formed by drawing the hair strand, that was brought to an appropriate temperature, over the lower, V-shaped arm 18 and the outer side, that is not visible in FIG. 7.
