Description

The invention relates to a hair styling device with a handle part, a heating part for heating of hair and a holding part that is in an open and a closed state is transferable, the hair between the heating part and the holding part can be inserted.

Such a hair styling device is known for example from US 4,426,567. There is a Handle provided on which an electrically operated heating element is held. The heating element is elongated and serves to heat a user's hair. About in A scissor-shaped holding part is pivotable in the transition region of the handle to the heating element appropriate. The holding part is also elongated and in terms of its shape adapted the heating element. With the help of an operating lever, the holding part can be operated by a user be pivoted into a closed state and an open state. In the open state, the hair can be inserted between the heating element and the holding part become. The hair can then be wrapped around the heating element and this way be shaped.

From US-A-1,865,655 is an electrically operated curling iron for hair at the beginning The type described is known, in which the holding part around a bearing point formed on the handle part is pivotable until the holding part rests on the surface of the heating part. The Holding part is connected to two opposing jaws that by hand for Longitudinal axis of the holding part are pivotable so that they are applied to the heating part Hold the holding part against the surface of the heating part and partially grasp it. On the Hair that is wound up on the heating element is thus pressed against the surface of the jaws Heating part pressed.

If the hair is inserted between the heating element and the holding part, they are closed Condition of the holding part pressed against the heating element. The emerging Pressure on the hair depends on the distance of the hair from the swivel axis. In the vicinity of the swivel axis, a greater pressure force acts on the hair than further away. In the known hair molding, it is therefore not possible to have the hair on the press the entire length of the holding part evenly against the heating element.

The object of the invention is to provide a hair molding with which a uniform pressure the hair on the heating element is possible.

This object is achieved according to the invention in the case of a hair molding of the type mentioned at the outset solved in that a pressure part is provided for generating a pressure force on the hair is arranged between the heating part and the holding part and that the pressure part is held resiliently on the hair styling device. So it is for pressing the hair on separate pressure part provided. This is independent of the holding part. This brings the Advantage with itself that the pressure force is also independent of the holding part. Thereby it is achieved that it does not matter what distance with a pivotable holding part have the hair to be pressed from the swivel axis. Instead, the hair pressed evenly along the entire length of the holding part by the pressure part. The called even pressing the hair is, as mentioned, by the between the Heating part and the holding part arranged, resilient pressure part generated. This can be due to different types can be realized.

So it is possible, for example, to provide an elastically deformable pressure part, which by the inserted hair is pushed back. in this case the contact pressure is dependent on the deformability or elasticity of the pressure part. It is also possible to print the part to be stored resiliently so that the spring, e.g. Compression or coil spring, Leaf spring, rubber or spring-elastic element or the like. squeezed and so that the printed part is moved. In this case, the pressure force depends on the Spring constants of the spring. This has the advantage that the pressure exerted by the pressure part Contact pressure can be adjusted as required. For example, the pressure force can be a corresponding deformability or elasticity of the pressure part itself or by a Corresponding spring constant of the spring supporting the pressure part can be influenced. there the setting of the pressure force, as explained, is independent of the holding part in all cases. With the arranged between the heating part and the holding part and for generating A pressing device on the hair provided pressure part is thus a hair styling device Available, with an even pressing of the hair with a predetermined pressure is possible.

In an advantageous embodiment of the invention according to claim 2, the pressure part held resiliently on the holding part, the hair between the heating part and the Print part can be inserted. The pressure part is therefore coupled to the holding part and forms with it one unity. in this case the hair is between the heating part and the pressure part inserted and can then either around the heating part or around the pressure part and the holding part be wrapped around. The advantage of this embodiment is that it is simple Construction. Furthermore, this embodiment of the hair styling device is particularly simple manageable by a user.

In another advantageous embodiment of the invention, the pressure part is resilient held on the heating part, with the hair between the holding part and the pressure part can be inserted (claim 3). The pressure part is therefore assigned to the heating part. For example be realized in that the pressure part is integrated in the heating part and, if necessary is even heated. in this case, the hair between the pressure part and the holding part inserted. The advantage of this embodiment of the hair styling device is that that the user has almost no difference in appearance and handling in comparison to the known devices.

In an advantageous development of the invention according to the features of claim 4, in which the heating part has an axis, guide means for radial guidance of the Print part provided. The heating element is, for example, an elongated heating element realized. The radial guidance of the pressure part for this purpose ensures that the hair is special be pressed evenly by the pressure part. Especially when it comes to linking the pressure part with the holding part in this way the hair over the entire The length of the holding part is pressed evenly against the heating part.

In an advantageous embodiment of the invention according to the features of claim 5 is the pressure part with two, in particular at opposite ends of the Springs, rubber elements or the like arranged in the pressure part. elastic means kept. In order to it is achieved that the pressure part a substantially even with one-sided loads creates even pressure on the hair. In this respect, too, this becomes uniform Pressing further improved.

It is particularly useful if the springs are arranged such that they generate a spring force in the radial direction. This makes it particularly possible Determine the effect of the spring force on the hair relatively precisely in advance. This makes it easier precise and reproducible setting of the spring force and thus the effect on the hair Pressure force.

In a particularly advantageous embodiment of the hair styling device according to the invention According to the features of claim 7, a stop is provided on which the holding part in closed state.

The stop can be provided in the area of the free end of the hair styling device (Claim 8), that is, for example, in the case of a pivotable holding part on the one of which Swivel axis distal end. However, it is also possible that the stop in the area of the handle part of the hair styling device is provided, for example in one pivotable holding part in the region of the actuating lever connected to the holding part. In this case, in particular, the stop can also act as a barb in the latter possibility or the like.

In an advantageous development of the invention, the pressure part when the Holding part on the stop between one resting on the heating part or on the holding part Position and a position forming a gap.

If no hair is inserted, the pressure part lies on the holding part in the closed state or on the heating element. If the holding part is now opened, the hair can be inserted become. If the pressure part is attached to the holding part, the pressure part is attached to the Closing the holding part of the hair pushed back towards the holding part and thus opens the gap mentioned. The hair is then between the pressure part and pressed on the heating element. However, if the pressure part is part of the heating part, it will Pushed the pressure part back towards the heating part when closing the holding part and opens the mentioned gap. The hair is then between the pressure part and the holding part pressed.

In both cases, the pressure applied to the hair is completely independent of the holding part. This results from the abutment of the holding part on the stop. One if necessary spring or the like acting on the holding part only has the consequence that the Holding part is pressed against the stop. Due to the stop, however, the spring can do not act on pressing the hair. As already explained, this is the pressure force on the hair regardless of the holding part or only depending on the pressure part and its design.

It is particularly expedient if a limitation for a maximum gap is provided are (claim 9). If there is too much hair in the hair styling device, it will Pressure part pressed against its limit when the holding part is closed. As a consequence, that the holding part is lifted from its stop and the hair styling device with it the hair is opened again. This ensures that not as many hairs in the Hair styling device can be inserted or that the user such a situation is at least displayed.

It is advantageous according to the features of claim 11 if the pressure force of the Holding part on the stop is greater than the pressing force of the pressure part on the hair. On This ensures that the pressure part is always pushed back by the inserted hair and only after that, if too much hair is inserted, the holding part is lifted off and is opened with it. The different pressure forces can be used of springs can be set by appropriate spring constants. Furthermore there is advantageously the possibility of the pressure force of the spring individually by the user adjust. For example, the spring preload of the corresponding adjustment means, like screws or the like be individually changeable.

In an advantageous development of the invention according to claim 12, the pressure part is detachable held. This makes it possible to remove the pressure part, for example for cleaning purposes or to exchange them entirely. It is also possible to make different structural designs, in particular different geometries of the pressure part use.

Further features, possible applications and advantages of the invention result from the following description of exemplary embodiments of the invention, which are shown in the figures of the drawing. All of the features described or illustrated, individually or in any combination, form the subject matter of the invention, regardless of their summary in the patent claims or their dependency, and regardless of their formulation or representation in the description or in the drawing.

shows a schematic longitudinal section of an embodiment of part of a hair styling device according to the invention, and

Fig. 2

shows a schematic cross section through the part of the hair styling device of FIG. 1 along the plane I - I of FIG. 1.

A hair styling device usually has a handle part 13 and a heating part 12. The heating part 12 (shown in dashed lines) is attached to the handle part 13 and can be electrically or gas operated be heated. The heating part 12 is an elongated heating element with an essentially circular cross section. Through the heating part 12, a longitudinal axis of the Hair styling set.

1 and 2 show a holding part 1 to which a pressure part 2 is assigned. The Holding part 1 and the pressure part 2 are elongated and have approximately the same length like the heating part 12. The holding part 1 and the pressure part 2 are connected to one another and form so far a unit.

The holding part 1 is pivotable about a bearing 3 approximately in the area of the transition from the Heating part 12 attached to the handle part 13. Furthermore, the holding part 1 with an operating lever 4 provided, which is arranged in the region of the handle part 13 and assigned to this is. With the help of the actuating lever 4, a user can hold the holding part 1 with the pressure part 2 transfer from a closed state to an open state and back. In In the closed state, the holding part 1 with the pressure part 2 bears against the heating part 12. in the open state, the holding part 1 with the pressure part 2 is pivoted away from the heating part 12 and is no longer due to this.

In the area of the actuating lever 4, a spring (not shown) is provided, which is supported on the handle part 13 and the actuating lever 4 that the holding part 1 of the Spring is always pressed in the closed state. Furthermore, in the area of Free end of the holding part 1 on the heating element 1, a stop 5 is provided, on which the Holding part 1 abuts in the closed state. The stop 5 is particularly from the 1. By said spring acting on the operating lever 4 the holding part 1 with a pressure force dependent on the spring constant of the spring pressed against the stop 5 in the closed state. Instead of the stop 5 can also in the area of the handle part 13 and the actuating lever 4 a coupled to the holding part 1 Barbs (not shown) or the like may be provided.

The pressure part 2 is elongated and advantageously has an arcuate shape Cross-section. This can be seen in particular in FIG. 2. Of course there are others too Geometries in adaptation to the geometry of the heating part 12 are conceivable. With its area 6 the pressure part 2 is in the closed state on the heating part 12. The geometry of the Surface 6 is adapted to the heating part 12 for this purpose.

The pressure part 2 is, in particular, two or more springs 7, 8 with the holding part 1 connected. The springs 7, 8 are in the region of the ends of the pressure part 2 and thus also in the Area of the ends of the holding part 1 arranged. Furthermore, the springs 7, 8 are approximately radial to the longitudinal axis of the heating part 12 and thus also approximately radially to the pressure part 2 aligned. The springs 7, 8 are for example on the holding part 1 and the pressure part 2 protruding pins attached. The pressure part 2 is thereby detachable from the holding part 1 and can be removed from it and replaced if necessary.

The holding part 1 and the pressure part 2 are each with guide means 9 at their two ends provided with which the pressure part 2 is guided in the radial direction. The pressure part 2 can so that they can be moved in the radial direction. This can be seen in particular from FIG. 1. By appropriate design of the guide means 9 is also a certain pivotability of the pressure part 2 about its longitudinal axis can be achieved.

In the open state of the holding part 1, the pressure part 2 by the springs 7, 8 of the Holding part 1 pushed away. There is a distance z between the pressure part 2 and one the limiting part 10 attached. This is shown in particular in FIG. 2. By this distance z, the pressure part 2 can be pressed into the holding part 1 until it abuts the limit 10.

If the holding part 1 is closed without hair being inserted, the holding part 1 rests the stop 5 and the pressure part 2 with its surface 6 on the heating part 12. That state is maintained by the spring acting on the operating lever 4. this is the Condition in which the hair styling device is usually stored or transported.

For use, the holding part 1 is opened and the user places the hair to be shaped between the heating part 12 and the open holding part 1. Then the holding part 1 is closed and, as explained, with the spring force associated with the operating lever 4 Spring pressed against the stop 5. When closing the pressure part 2 of the inserted hair pushed back in the direction of the holding part 1 and thus in the radial direction postponed. The distance z between the pressure part 2 and the limit 10 is thus smaller. This is tantamount to creating a gap between the Pressure part 2 and the heating part 12, in which the inserted hair is pinched.

In this state, the user can shape the inserted hair. The hair heated by the heating part 12 and pressed by the pressure part 2 against the heating part 12. The on the pressure force acting on the hair is only dependent on the spring constants of the two springs 7, 8. Because of the stop 5, this pressure force is not dependent on the holding part 1 or the spring acting on the actuating lever 4. By using it same springs 7, 8 at the respective ends of the holding part 1 and the pressure part 2 there is an even pressure force on the hair along the entire length of the Pressure part 2 reached.

The user can now insert the hair around the heating element 12 or around the holding part 1 wrap and shape with it. With such a looping or pulling through Hair through the hair styling device essentially acts only the spring force of the springs 7, 8. The spring force of the spring acting on the operating lever 4 plays practically none Role. The pressure force acting on the hair is also essentially independent from the looping of the hair around the holding part 1.

If the user places too much hair between the heating part and the pressure part 2, this has the consequence that when the holding part 1 is closed, the pressure part 2 is completely in the holding part 1 is pressed in. The pressure part 2 thus comes to the limit 10 System, so that the distance z becomes zero. This is equivalent to having a maximum There is a gap between the heating part and the pressure part 2, but this is not sufficient, to pick up the inlaid hair.

Due to the too much inserted hair, the holding part 1 of the stop 5 against the Spring force of the spring acting on the actuating lever 4 is lifted off. This shows that User that he has put too much hair in the hair styling device, so that he now can repeat the process.

The spring constants of the springs 7, 8 are of the same size and are selected as they are for the Pressing the hair against the heating part 12 is desired. The spring constant on the Actuating lever 4 acting spring is larger, in particular much larger than that Spring constants of the springs 7, 8 are selected so that the pressure part 2 is completely complete in any case is inserted into the holding part 1 by the inserted hair before the holding part 1 stands out from the stop 5.
