Abstract

A hair removal apparatus with a housing and an actuator head movable in the housing. The actuator head accommodates an actuator system that removes the hairs and is adapted to be driven by an electric drive mechanism arranged in the hair removal apparatus. The actuator system is movable into at least one active position for hair treatment. The actuator head has only one of its ends rotatably mounted on the housing. The actuator head is readily accessible from the one side, thus enabling hairs in problem areas of the skin surface to be removed.

Description

The invention relates to a hair removal device according to the preamble of patent claim 1.

From the DE 36 10 736 A1 is a hair removal device, here an electrically operated razor, known, in which an actuator head, here a short hair trimmer, is movably mounted on the housing. The short-hair trimmer consists of two substantially parallel to the axis of rotation of the Aktuatorkopfes Scherfolien, below each of which an oscillating, consisting of individual laminations lower blade is slidably disposed. The short hair trimmer is the only actuator system in this electric shaver.

From the US 5165172 A a hair clipper is known which has a tubular housing, on whose one end face a shaving head is rotatably mounted. In this case, the axis of rotation of the rotary joint formed directly on the housing front side corresponds to the longitudinal axis of the housing. Such hair trimmers are used in hairdressing and are not suitable for self-shaving even for ergonomic reasons.

From the DE 198 59 017 C1 furthermore, a hair removal device designed as a hair clipper is known in which the actuator head has two different actuator systems. In this case, a single cutting comb two cutting blades are assigned, each of which can be coupled depending on the pivotal position of the Aktuatorkopfes to the housing with a drive element of the drive. As a result, the cutting comb having two rows of cutting teeth can be brought by means of pivoting movement into an optimum cutting position to form a skin surface.

The formation of two cutting blades on a cutting comb also advantageously allows a different formation of both the teeth on the cutting comb as the teeth on the two cutting blades, for example in such a way that the width of a row of cutting teeth is formed much narrower than the width of the other row of cutting teeth. This results in that one can cut longer hairs, for example, with one row of cutting teeth and shorter ones with the other pair of teeth. To make this possible, the Aktuatorkopf must be pivoted about a pivot axis, which lies outside the cutting comb here. It arrives according to the FIGS. 6 and 7 of the DE 198 59 017 C1 the cutting teeth 41 to rest against the housing 1 and is not active in this position, while the cutting teeth 40 according to Fig. 7 now free to the outside protrudes and contact with the skin can absorb. According to Fig. 6 Before the pivoting of the actuator head, the cutting edge row 41 took its active, that is its shaving position, while the cutting edge 40 was in its rest position. By arranged outside the cutting comb pivot axis of this is rotatable only to a limited extent in the housing. The storage of the cutting comb in the housing is relatively expensive and expensive.

In this hair clipper from the change of a cutting comb to the other cutting comb and the device must be rotated in the hand, because the direction of the cutting plane has shifted from one to the other side of the housing. As a result, the electrical switching device passes from the outside, where it was slightly operable from the thumb, to the inside of the hand and is therefore no longer easily accessible.

The object of the invention is therefore to provide a hair removal device in which the Aktuatorkopf is easily accessible, so that you can remove hair on problem areas of the skin surface. The storage and installation of the Aktuatorkopfes in the case should be simple and inexpensive. At the same time it should also be possible to bring by simple adjustment of the Aktuatorkopfes multiple actuator systems in their active operating position.

This object is achieved by the characterizing features of claim 1. Due to the one-sided storage of Aktuatorkopfes on the housing above disadvantages are avoided. As a result of the free access of the actuator systems from one side of the actuator head, the individual actuator systems can be guided particularly easily from the free end of the actuator head to the skin surface, in particular in hard-to-reach areas, such as behind the ear or next to or under the nose , The single-ended actuator head not only provides a hair treatment device that is novel in appearance over the prior art, but also provides technical and everyday benefits, some of which have been previously mentioned. In addition, results from the one-sided storage of Aktuatorkopfes in the housing better cleaning ability of Aktuatorkopfes, since it is more accessible. Also, the actuator head can be easier to assemble or disassemble, since it only needs to be attached to a bearing point or separated from it. By forming a bearing arm projecting on the housing, the actuator head can be adapted particularly well as a freely cantilevered element.

The invention results in a simpler housing design. However, in the one-sided bearing arrangement, the formation of the bearing must be made so stable that the forces acting on the actuator head bending forces when applying this to the hair surface of an operator can be taken harmless of the camp. However, this is not a problem for a good designer.

Due to the features of claim 2, the receiving space for receiving the Aktuatorkopfes be kept in the housing in the smallest limits. The smallest receiving space is achieved when the axis of rotation of the actuator head runs centrally to the actuator systems and the actuator systems are made as small as possible in their dimensions.

According to the features of claim 3, the axis of rotation of the Aktuatorkopfes extending in the longitudinal direction of the treatment levels of the individual actuator systems, ie substantially parallel to these, whereby a particularly simple handling of the hair removal device is formed. Similar to a rotating drum, the actuator head can be rotated about its axis of rotation until the corresponding actuator system, such as a short hair trimmer, points radially outward away from the hair removal device, ie, its treatment plane perpendicular or at an angle to the longitudinal axis of the housing and, moreover, substantially parallel runs to the axis of rotation. In this way, an actuator system can be easily zoomed to the hair surface to be treated, without causing the case is a hindrance.

This results in accordance with the features of claim 4 between the bearing arm and the Aktuatorkopf a receiving space which receives the Aktuatorkopf, so that when balanced dimensioning of the Aktuatorkopfes this does not protrude beyond the side surfaces of the housing. As a result, the cutting systems when depositing the hair treatment device on a hard shelf are largely protected from external damage. In addition to the housing in the direction of the bearing arm protruding walls of the actuator head is laterally protected between them and yet freely accessible from one side as from above.

Characterized in that the Aktuatorkopf forms a body of revolution and thereby it is rotatable about a rotation axis in the housing of the hair removal device, the entire circumference of the Aktuatorkopfes can be used to form a plurality of actuator systems, each with a rotation of the Aktuatorkopfes 360 ° once the desired treatment level reach for the hair. The device can without a position change be held in the same position by the hands. Of course, stops may be formed on the actuator head, so that it is rotatable only less than 360 ° in the housing in the context of the invention.

As a result of the circumferential design of the individual actuator systems on the actuator head, in its simplest embodiment it assumes a roller-shaped or drum-shaped form, with the axis of rotation of the actuator head also extending in the longitudinal direction of the individual actuator systems. If only two actuator systems are formed on the actuator head, then these are advantageously arranged diametrically opposite one another and the actuator head takes the form of a cuboid, whose circumferential end faces are slightly curved outwardly to produce a better contact with the skin of an operator.

It will be noted that many combinations of actuator systems are possible on the actuator head of a hair treatment device, such as combinations of long hair trimmers, medium hair trimmers, short hair trimmers, beard trimmers, epilation devices, etc.

In the one-sided storage of Aktuatorkopfes is according to the features of claim 6 on the side surface of a bearing pin out, which engages in a formed on the housing bore in register and is fixed there fixed. In this case, the pin forms a closely tolerated sliding fit with the bore, in which the actuator head can rotate without play. As fixing elements, for example snap rings or other Verclipsungen can be selected, which fix the actuator head on the pin in the housing.

If the actuator head is rotated by hand about its axis of rotation to bring a desired hair processing system in the active position of the Aktuatorkopfes, this is the simplest and most cost-effective solution (claim 7). However, it is in this case according to the features of claim 8 advantageous if locking means are provided between the actuator head and the housing, which indicate to an operator when the desired actuator system has taken its correct position relative to the housing and a shaving or plucking operation can be started , Subsequently, the Aktuatorkopf be brought into its rest position, which can also be done automatically after switching off the device of this itself. At the same time, the actuator head is fixed in a rotationally fixed manner in order to prevent unintentional rotation of the actuator head during a treatment process of the hair.

As a further alternative to the adjustment of the Aktuatorkopfes serves according to the features of claim 9, an electrically driven adjustment for the Aktuatorkopf which rotates the actuator head with each actuation of the switch for the adjustment until the switch is turned off again. It is also conceivable that with each actuation of the switch, the electric adjusting device rotates the actuator head so far that each of the next actuator is brought into its machining position. Although such an electronically controlled, electric drive device for the adjustment of the actuator head is more complicated than a manual operation, it represents a very comfortable solution.

According to the features of claim 10, the electric adjusting device consists of an additional cutting system arranged electrically driven motor, which rotates the actuator head via a transmission device in the desired active position. In this case, the transmission device consists of a gear arrangement between the drive motor and the Aktuatorkopf, in which case the bearing pin can be formed simultaneously as a gear which is coupled via a connected to the drive shaft of the drive motor gear. But it is also a timing belt conceivable that connects the drive shaft of the electric motor with the journal. Of course, transmission belts or other torque transmitting gear units are possible, which are not mentioned here for the sake of simplicity. Of course, it would also be quite possible to couple the drive motor directly to the pin of Aktuatorkopfes to save the transmission completely.

According to the features of claim 11, an electrical positioning device is formed in the hair removal device, which detects the rotational position of the Aktuatorkopfes and sends corresponding signals to a formed on the circuit board control electronics. The control electronics then in turn sets the drive device in motion when the desired position of the actuator head desired by an operator to be changed.

As Aktuatorköpfe example Kurzhaarschneider in the form of one or two sheets and adjacent knife, a central cutter, a long-hair trimmer or a plucking device for plucking hair, which are circumferentially formed on the Aktuatorkopf and are driven by at least one or more drives. In addition, the actuator head can also be provided with a parking position, ie, if this is rotated in this plane, all existing actuator systems are disabled. The rest position can also be advantageous in particular when the hair treatment device is used in a cleaning center for cleaning the Aktuatorkopfes; then, by forming one or more slits on the protective surface, they could still be used as input and output for the cleaning liquid.

In the resting or parking position so the actuator can not be activated. They can only be activated if the actuator head has been inserted into a cleaning center to clean it.

By the features of claim 13, a drive device for the actuator head is provided, which consists of a linear motor, wherein the linear motor is formed within the Aktuatorkopfes. Linear motors have the advantage over conventional rotating electric motors that they can do without transmission devices and can directly transmit the oscillating motion to the actuator system. Such linear motors can be well integrated in Aktuatorkopf because they can be built very small dimensions.

According to the features of claim 14, a particularly easy to manufacture and absolutely watertight linear motor is specified, which is fixed swinging on both sides of the actuator head. The linear motor preferably vibrates this in a hair cutting system in such a way that the lower blade moves relative to the upper blade or the blade block relative to the shaving foil in order to be able to cut off hair reaching between the cutting edge. The drive can of course also be used in Epiliereinrichtungen.

Due to the features of claim 15, a simple and inexpensive to produce linear motor is created, which can be integrated to save space in the actuator head of a hair removal device.

That in the FIGS. 1 to 5 Hair treatment device 1 shown in perspective as a razor consists of a housing 2, on the upper side 3 at the left edge ( Fig. 1 to 4 ) of the housing 2 without forming a step smooth surface, a single bearing arm 4 connects upwards. The bearing arm 4 forms with its left side surface 45 a common housing side 45 which extends flat. The width of the bearing arm 4 is about one fifth of the width of the housing 2. Between the bearing arm 4 and the top 3 of the housing 2 results in a receiving space 6, which serves to receive an actuator head 7. In the FIGS. 1 to 6 the actuator head 7 consists of a razor head, which could also be replaced by an epilation head with integrated razor part (not shown). Centered to the razor head 7 is a rotation axis 8, which engages in the bearing arm 4. On the outer surface are at the razor head 7 after the FIGS. 1 to 5 two actuator systems 10, 26 designed as hair cutting systems are arranged diametrically opposite one another, of which the actuator system 10 is a short-hair trimmer ( FIG. 1 ) and the actuator system 26 a long-hair trimmer ( FIG. 3 ). In FIG. 6 the two actuator systems 10, 26 are arranged not diametrically (180 °) but at right angles (90 °) to each other.

The razor head 7 has in Fig. 1 that position occupied, which corresponds to the active plane 22 of the short hair cutter 10 and an integrated central cutter 23. Active level 22 is the level that an actuator system 10, 26 must assume before a correct hair treatment with the device 1 can be made. The short-hair trimmer 10 consists of two longitudinally parallel to the rotation axis 8 extending, outwardly curved shear plates 24, 25, under each of which a lower blade (not shown) oscillating back and forth. The same applies to the central cutter 23. The active position of the Kurzhaar- and middle cutter 10, 23 is selected so that during contact of the active plane 22 on the skin surface (not shown) of an operator, the housing 2 from the surface obliquely or vertically outwardly protrudes and thus does not interfere with the shaving process.

The razor head 7 may be either by hand (not shown) or electrically driven about its pivot or bearing axis 8, as is known Fig. 2 evident. If the razor head 7 is rotated by hand about its axis of rotation 8, it is advantageous if, as soon as the short-hair trimmer 10 or the long-hair trimmer 26 (FIG. Fig. 5 ) have reached the active plane 22, between the razor head 7 and the bearing arm 4 locking means formed (not shown) lock the razor head 7. The locking means may for example be a ball acted upon by a spring, which engages in a recess (not shown) formed on the side surface 27 latching. For two actuator systems 10, 26, two recesses would then be necessary on the razor head 7. Since such a locking means are already well known to a simple designer and he can also refer to the common textbooks, will not be discussed here for the sake of simplicity.

The razor head 7 is according to Fig. 6 about a on the left side surface 27 centrally projecting bearing pin 28 in a formed in the bearing arm 4 fitting bore (not shown) rotatably mounted, wherein the shaving head 7 according to Fig. 4 can be rotated in both directions of rotation 29, 30. On the journal 28, a groove 31 is circumferentially formed, which serves for fixing in the fitting bore (not shown) on the bearing arm 4. For this purpose, preferably in the Paßbohrung trained in an annular groove, resilient retaining ring (Not shown) be attached, which engages during insertion of the bearing pin 28 into the fitting hole in the groove 31 and thus the shaver head 7 stationary on the bearing arm 4 but freely rotatable about the axis of rotation 8. As previously mentioned, a general mechanical engineer also such simple bearings and fasteners are well known and he can also refer to the common textbooks. For this reason, the sake of simplicity will not be discussed in more detail here and include such simple solutions to the subject of the application.

As the shaver 1 according to Fig. 2 shows, inside the housing 2, an electrically operated drive motor 14 is formed, which is connected via not shown electrical lines with the switches 19, 20 for the rotation of the Aktuatorkopfes 7 in the active position of the shorthair or Langhaarschneidersystems, which then via further electrical connections with an accumulator 32 formed in the housing 2 can be coupled. The accumulator 32 is electrically controlled by a printed circuit board 33. Since such arrangements have been made for a long time by the razors sold by the applicant itself to the prior art, will not be discussed further here; but they should still be the subject of the application.

The drive motor 14 is in accordance Fig. 2 via a transmission device 34 with the bearing pin 28 of the Aktuatorkopfes 7 in rotary connection. In this case, the transmission device 34 consists of a plurality of toothed gears 35, wherein the output-side wheel 36 serves as a belt drive and therefore drives a belt 70. The belt 70 is connected to a journal 37 formed on the journal 28. At this point it is mentioned that the teeth formed on the inside of the belt 37 and the teeth formed on the wheel 36 on the circumference are not shown in the drawing for the sake of simplicity. However, the gear formed on the bearing pin 28 is in Fig. 2 shown while in Fig. 6 For the sake of simplicity, it is merely indicated as a groove, but correspondingly Fig. 2 of course also has teeth.

In Fig. 2 is further mounted in the bearing arm 4, an electrically operated position detector 38 to a mounting plate 39 which corresponds to the side surface 78 formed windows 40, which are evenly distributed around the circumference, then, when the desired actuator system 10, 26 in the correct actuator - or active plane 22 is to stop the electrically driven drive motor 14 via electrical lines, not shown.

In Fig. 5 was the Aktuatorkopf 7 turned so far that from above a cleaning opening 41 is accessible, then the water (represented by a drop 42) can be filled in the Aktuatorkopf 7. A faucet 43 symbolically represents the cleaning fluid source.

In Fig. 7 Finally, an electric drive device 79 is shown, which consists of a linear drive motor 44. This linear drive motor 44 is, for example, for installation in the actuator head 7 of the shaver after the FIGS. 1 to 6 suitable, according to Fig. 7 the hatched rectangles formed on the right and left of the linear drive motor 44 represent parts of the two side walls 47, 48 of the actuator head 7, which carry the linear drive motor 44, in the future only called a linear motor.

The linear motor 44 is after FIG. 7 essentially of a watertight sealed, box-shaped stator shell 49, at the two-sided lateral ends of leaf spring-like outer spring elements 50, 51, which serve as swing bridges, are attached. The spring elements 50, 51 are connected at their other end fixed to the side walls 47, 48 of the Aktuatorkopfes 7. In this way, the stator shell 49 can swing in the horizontal direction according to the arrows 52, 53 back and forth. The outer spring elements 50, 51 may preferably be made of metal and may simultaneously form the power supply for the linear motor 44. At the bottom of the stator shell 49, a stator 55 is attached with attached magnet 56 at the top.

On the side walls of the stator 55 extend upward depending on a vibrating spring 57, 58, which are connected to one another via a coil core 59. From the spool core 59 extend down two juxtaposed, cylindrically shaped core portions 60, 61 which are firmly enclosed by a respective annular coil 62, 63. The free ends of the core portions 60, 61 terminate at a short distance from the magnets 56 on the stator 55 and thus form a predetermined gap S. The core portions 60, 61 are arranged so that each are arranged between a north and a south pole of the magnet 56 , The North Pole is N and the South Pole is S in Fig. 7 displayed.

The leaf springs 57, 58 guarantee after FIG. 7 on the one hand, the exactly predetermined gap S and on the other hand, they form the resonant springs, which are necessary for the resonance mode. However, the leaf springs 57, 58 may also be separate elements, such as compression springs, which may be inserted between the stator 55 and core sections 60, 61.

The operation of the shaver according to the FIGS. 1 to 7 is the following:

First, it is decided which cutting system 10, 26 should be used. If the short-hair cutting system 10 (system 1) is to be used first, it is not necessary to operate the short-hair trimmer button 19, since the razor 1 according to the FIGS. 1 and 2 has already assumed this position, ie, the two short hair trimmer 10 running parallel to one another and the middle cutter 23 arranged therebetween are already in the absolutely correct active plane 22.

The device can now after the FIGS. 1 and 2 be turned on the on / off switch 13 and the control electronics controls not shown in the drawing power connections formed in the actuator head 7 linear motor 44 ( FIG. 7 ). Due to the magnetic excitation of the coil core 59 and the core sections 60, 61 integrally connected thereto by the coil 62, 63, an alternating magnetic field results at the core sections 60, 61, which causes them to vibrate relative to the stator 55. As shown by the arrows 52 and 53, the core portions 60, 61 oscillate in opposite directions to the stator 55, wherein the stator 49 is caused by the acceleration forces in oscillating motion, which is favored by the spring elements 50, 51. The oscillating movement of the stator shell 49 is transmitted via the spring 64 to the movable part 65 (blade block), which thus forms the shearing movement with respect to the stationary part (shaving foil). It can now slide along with the Kurzhaarschneider 10 on the skin surface of an operator and thereby finest hairs are cut off.

The drive of the linear motor 44 operates oscillating in very high short-stroke frequencies, wherein the entire linear motor 44 is completely waterproof embedded in the stator shell 49. The actual oscillating moving shear parts are arranged outside of the stator shell 49 and thus can be easily cleaned with water without water can penetrate into the interior 67 of the linear motor 44. Of course, instead of the shearing parts 65, 66 on the stator shell 49 at different locations different types of drive elements can be coupled directly and without seal. Such drive elements can be, for example, long-hair trimmers, short-hair trimmers, center cutters and other actuator systems that can be driven by oscillating motions. The linear motor 44 represents a second invention.

If you want to cut sideburns or profiles on the hair head, you have to FIG. 3 bring the long-hair cutter 26 in the active plane 22. This is achieved by doing according to FIG. 1 and 2 operated the operation button 20 for the long-hair trimmer (system 2). Now, via electric control means (not shown) of the drive motor 14 is set in rotation, which in turn via gears 35, 36, 37 and the timing belt 70, the actuator head 7 about its axis of rotation 8 so far rotated until the long-hair trimmer 26, the active plane 22 in accordance FIG. 3 has reached. In this position, a position detector 38 outputs an electrical signal to the electronics of the circuit board 33, so that the drive motor 14 turns off. In order to determine the correct position of the actuator head 7, windows 40 are uniformly distributed on the side wall 47 on the periphery, by which the position detector 38 recognizes the desired position of the actuator head 7, this data is passed on to the control electronics, so that from there then the electric motor 14 is turned off.
