Description

The invention relates to a comb with a plurality of teeth according to the preamble of claim 1, a hair and / or beard cutting machine with such a comb or a comb for a hair and / or beard cutting machine according to the preamble of the dependent claims 10 and 11 .

Combs are well known and consist of one Body element and teeth, the teeth of Body element are arranged leading away and one each have front tooth portion removed from the body member. There are different types for different purposes shaped teeth, in particular tooth length, tooth width and Tooth gap width between the individual teeth depending on Application needs are designed differently.

FR 2 808 979 A1 describes a device for cutting hair known. It has a number of teeth. On the A plastic foam is glued to the tooth flanks. Every tooth of the Device has an opening into which a pin is inserted which keeps the teeth aligned with each other. presses the user on the first and last tooth of the establishment the hair is held on. By pulling the device From the bottom up, the hair can be cut to the desired length brought, held there and then cut off.

US 3,638,665 describes a comb with two individual Comb parts. Each, comb part is like one in itself known comb with a body element and a variety of teeth leading away from the body element. The Front tooth sections of the two comb parts can be made using  an actuator aligned at an angle to each other become.

Hair and beard trimmers are also generally known with a cutting unit and an additional comb, which the Cutting device from z. B. the facial skin or one to be shortened Beard spaced and at the same time the whiskers to the cutting unit leads. Advantageous embodiments of such hair and Beard trimmers show how, for example, from the DE 36 23 591 A1 results instead of a fixed comb Clip-on combs so that a clip-on comb can be used as required desired tooth length, tooth width and the like on the Hair and beard clippers can be put on.

Hair combs with a central, longitudinal body element and teeth that protrude opposite from two sides of the body element. One of these rows of teeth designed in this way has one narrow tooth gap width, the other one relative to it larger tooth gap width. Such a comb is thus more universally applicable, since it depends on  Hair texture two different tooth arrangements provides.

As can be easily seen, there is a long one Problem in that consequently for many different Different combs or applications Attachable combs are to be kept ready.

The object of the invention is a comb, a hair and / or beard cutting machine or a comb for hair and / or Beard trimmers to improve advantageously so that a more universal use is possible.

This task is carried out by a comb with the characteristics of Claim 1, a hair and / or beard cutting machine with the features of claim 10 or one Clip-on comb for hair and / or beard trimmers with the Features of claim 11 solved.

For a comb with at least one body element and one Variety of teeth, the teeth from the body element are arranged leading and one each from Have body element removed front tooth section, enables multifunctional use, if at least one tooth, especially one Variety or all teeth, designed and / or is or are arranged that at least the respective front Tooth section between different positions is adjustable. This allows one or more teeth to be easily and Way to the current situation when cutting one Hair or barts.

Advantageous refinements are subject-dependent Expectations.

A basic embodiment is that Reduced tooth gaps between adjacent teeth or  can be enlarged in which the neighboring teeth by lateral shift in the attachment area on the body element as Whole move away from each other or towards each other. This is thus due to the tooth base on the body element Even adjustment up to the front tooth section the tooth gap between adjacent teeth.

According to another embodiment, the same with the first Embodiment is combinable advantageously pivoting the front Tooth section opposite the tooth attachment on the body element intended. For this purpose, either the tooth, preferably near the base on the tooth body or Body element, curved to the side and / or to pivoting tooth points in the transition area to Body element or a joint close to it, which is a pivoting of the front tooth section towards the body element.

A guide in particular can be used for adjustment be used advantageously, the backdrop guide in is essentially based on the tongue and groove principle. In advantageous embodiment are either in Sections of the teeth or in corresponding opposite Sections of an actuating element abutment, in particular grooves or through openings. For the corresponding counter element, i.e. the actuating element or the corresponding sections on the teeth corresponding spring elements, preferably bearing journals, Locking pins, tooth sections or the like are provided, which in the corresponding grooves or through openings intervention. By relative to the movement of the Actuating element when operated obliquely or arcuately running grooves or through openings become the teeth in this area compared to the base body and depending on Embodiment also adjusted relative to each other if that Actuator is moved.  

In a preferred embodiment, the actuating element can a linearly movable slide, but also a pressure or Rotary switches are used.

As engagement elements, which with an abutment cooperate, are in addition to the pins and grooves shown and through openings also other suitable adjustment means usable. This particularly includes racks and Gears or the like as well as elastic bands for automatic adjustment of the actuator in one Home position.

Such a backdrop guide and / or an arrangement of such tongues or pins on the one hand and grooves on the other or through openings can be one for all of the teeth Comb or also individually for a single or a selected plurality of teeth of the comb are formed. This allows the individual teeth of the comb to be adjusted further increased relative to each other.

In addition to one is particularly advantageous from the side adjacent teeth to be performed laterally Adjustment of the front tooth sections also a vertical one adjustability of the height of the front Tooth sections relative to the tooth body.

Advantageous embodiments are described below with the aid of Drawing explained in more detail. Show it:

Fig. 4 shows an alternative embodiment of such a comb attachment in two different views

Fig. 5A-5E different embodiments and shapes of such combs in plan view.

As can be seen from FIG. 1, a comb 1 essentially consists of a comb body or body element 2 and a plurality of teeth 3 , 4 , 5 . The teeth 3-5 lead away from the body element 2 , in a basic position, preferably evenly spaced from one another by tooth gaps 6 .

For the purposes of the description, a distinction is also made below into a front tooth section 7 and a rear tooth section 8 . The front tooth sections 7 of the teeth 3-5 end in the tooth tip and the teeth 3-5 are fastened or supported on the body element 2 via the opposite end in the region of the rear tooth section 8 .

Fig. 1 in this case represents an arrangement in which the individual teeth 3-5, which are attached to the rear end of the tooth portion 8 to the body element 2, are present in one piece with this. The transition between the rear tooth section 8 and the body element 2 is tapered in comparison to the remaining dimensions of the teeth 4 , 5 . When corresponding forces act on the teeth 4 , 5 , this enables them to be pivoted around, in particular, the tapering region 9 .

In the exemplary embodiment shown above, the centrally arranged tooth 3 has no taper in the transition region. In other possible embodiments, however, this central tooth 3 can also be designed in the same way as the teeth 4 , 5 adjacent to it and thus also be pivotable.

In order to enable the teeth 4 , 5 to pivot, an actuating device 10 interacts with the body element 2 and the teeth 4 , 5 . In the exemplary embodiment shown, the actuating device 10 is a slide which has pins 11 . The actuating device 10 , which is shown separately for the purpose of illustration, is placed on the body element 2 and the rear tooth section 8 in order to adjust the teeth 4 , 5 , the pins 11 coming into engagement with the rear tooth sections 8 .

In order to make it possible to adjust the front tooth sections 7 or the entire teeth 4 , 5 in the transverse direction, the actuating device 10 is linearly moved forwards or backwards in the longitudinal direction of the teeth 3 - 5 of the comb 1 , that is to say parallel to the central, fixed tooth 3 , The pins 11 of the actuating device 10 engage in abutments 12 which are formed in the teeth 4 , 5 .

In the illustrated embodiment, the abutments 12 are designed in the form of a through opening or groove in the rear tooth section 8 of the teeth 4 , 5 . In order to enable a lateral adjustment of the teeth 4 , 5 relative to the linear movement of the pins 11 , which engage in the corresponding abutment 12 , the abutment 12 is designed as a slotted guide at an angle to the longitudinal direction of the teeth 4 , 5 therein. Since the teeth 4 , 5 expediently have only a small cross-section, the teeth 4 , 5 are widened in the rear tooth section 8 , that is to say in the region of the abutment 12 .

Depending on the inclined position or rounded guiding of the abutment 12 , the respectively assigned tooth 4 , 5 is displaced more or less laterally when the actuating device 10 is shifted from the rectilinear rest position. In the exemplary embodiment shown, the abutments 12 of the teeth 4 on the left run from the direction of the body element 2 and the central tooth 3 with an increasingly increased inclination to the left. The abutments 12 in the teeth 5 on the other side of the middle tooth 3 run from the perspective of the body element 2 and the middle tooth 3 with increasing inclination to the right. By pushing the actuating device 10 with the pins 11 engaging in the abutment 12 forward or backward, the two groups of teeth 4 and 5, which are on the outside from the perspective of the central tooth 3 , are either towards the central tooth 3 or away from it pivoted.

Alternatively, a different arrangement can also be selected according to the tongue and groove principle described above for adjusting the teeth 4 , 5 via the link guide with the abutment 12 and via the pins 11 in the slide. In particular, it is possible to form pins on the preferably upper or lower side of the teeth ( 4 , 5 ) to be pivoted, which pins then engage in corresponding abutments or link guides which, for. B. are formed in the flat actuator. This has the particular advantage that the rear tooth sections 8 are not to be widened in order to be sufficiently wide to accommodate oblique abutments 12 .

The basic function of such combs thus consists of the adjustability of the tooth space width and / or the adjustment of the tooth position of the comb 1 or preferably a plug-on comb. As a result, a comb 1 can be adapted to the hair properties of a hair to be cut.

In the exemplary embodiment described above, the teeth 4 , 5 of the comb 1 are provided with a link guide into which guide pins of a slide engage, the guide pins being firmly connected to the body of the slide. When the slide is moved, the teeth are forcibly moved laterally due to the positive locking of the pins in the link guide. The movement of the slide can take place directly or by means of a pressure or rotary switch arranged on the slide. The specific movement of the teeth is determined by the design of the backdrop. An individual travel path can advantageously be assigned to each individual tooth.

FIGS. 2A-2C illustrates the comb 1 with the actuating means 10 in three different positions. The longitudinal dotted line shows the position in which the actuator would be located 10 in the respective tooth positions the pin 11. Fig. 2A illustrates the basic position, in which the bearing pin 11 would be located centrally in the abutments 12 of the guide mechanism. FIG. 2B shows the position in which the pins 11 of the actuating device 10 would be arranged at the end of the abutment 12 , which faces the body element 2 . Accordingly, the front tooth sections 7 of the teeth 3-5 are spread apart relative to the basic position. Fig. 2C shows the situation wherein the pin 11 located 7 facing end portions of the abutment would be located 12 in the front tooth portions. In this position, the front tooth sections 7 of the teeth 3-5 are pivoted towards one another.

As can be seen from the comparison of Fig. 1 and Fig. 2D, it is possible to form in verschiedenster embodiment, the actuating means 10.

As shown in FIGS. 1 and 2, a substantially planar extending ridge 1, Fig. 3 shows a comb 21, which can be mounted on a hair and / or beard trimmer. As in the exemplary embodiment described above, the plug-on comb 21 in turn has a comb body with a body element 22 on which the teeth 24 are mounted or fastened. An actuating device 30 in turn has pins 31 which engage in corresponding abutments 32 in the teeth 24 . By moving the actuating device 30 , the teeth 24 can again be pivoted laterally accordingly. Here too, of course, an embodiment with the reverse arrangement of pins on the combs and abutments on the actuating device can be implemented.

The actuating device 30 also has an actuating button 33 on the upper side, ie the side facing away from the teeth 24 , which can be gripped to move the actuating device 30 . In order to be able to securely mount the actuating device 30 over the body element 22 and the teeth 24 in the desired engagement position, apart from the necessary displacement play, a cover 34 is placed over the actuating device 30 . The cover 34 is fixedly or releasably attached to the comb body of the comb 21 . The actuating button 33 of the actuating device 30 projects through an elongated access opening, so that actuation of the actuating device 30 from the outside is possible on the one hand and on the other hand the displacement of the actuating device 30 remains restricted to the possible positions of the actuating button 33 within the access opening 36 .

In order to be able to place the comb on a hair and / or beard cutting machine, the comb 21 has a corresponding fastening device 35 . In the exemplary embodiment shown, the fastening device 35 is a simple cylindrical receptacle, so that the comb 21 can be placed on a correspondingly dimensioned front end of a hair and / or beard cutting machine. In the simplest case, the comb 21 is fixed on the hair and / or beard trimmer by a frictional connection. However, it is also possible to use corresponding locking elements or other fixing devices, which preferably enable the comb 21 to be removed from the hair and / or beard trimmer again at a later point in time.

In particular, in such an embodiment, it is also possible to simplify in place and in the longitudinal direction z. B. rod-shaped teeth with a view of the outer dimensions of flat teeth. As can be seen from FIGS. 3A and 3B, the teeth 24 extend downward, ie perpendicular to the direction of displacement and perpendicular to the flat orientation of the actuating device 30 . The teeth 24 z. B. U-shaped, as shown, or be flat.

While Fig. 3A illustrates such a comb 21 in assembled and functional arrangement of the individual elements, Fig. 3B is an exploded view of the individual components.

In the embodiment shown in FIG. 3, an operation knob is thus mounted on the slide actuator 30 constructed as 33, so that the actuator 30 itself directly the function of a switch occupies. Alternatively, however, it would also be possible, for example, to use a rotary knob or a further switch in the cover 34 , which then enable the actuating device to be adjusted via corresponding coupling elements, for example a toothed rack on the upper side of the actuating device in the case of a rotary knob. The cover 34 serves on the one hand to fix the actuating device 30 on the comb 21 and on the other hand also as a design element.

As can be seen from FIGS. 4A and 4B, combs 41 of a different design can also be used to implement the concept described above. As can be seen, the comb 41 , which in turn is designed as a plug-on comb, again has a comb body with a body element 42 and teeth 44 projecting therefrom. An actuating device 45 again serves to adjust the teeth. In the present case, however, the actuating device 45 is not pushed longitudinally over the surface of the teeth 44 , but is moved up and down perpendicularly thereto. The actuating device 45 has abutments 46 which engage directly with the cross sections of the teeth 44 . While in the exemplary embodiment shown, a central abutment leads vertically into the body element 45 , and thus does not laterally adjust the associated tooth when it is pushed on or pushed off, the other abutments 46 are designed to run obliquely or roundly from the lower outside of the body element 45 . The lower side of the body element 45 in the drawing is the side that faces the teeth 44 or is arranged around them. Depending on how far the actuating device 45 with its abutments 46 is pushed over the teeth 44 , the lateral teeth 44 are pivoted towards or away from the central tooth.

As a variation on the embodiments described in the context of FIGS. 1-3 with horizontal slide designs which are slid longitudinally over the teeth, the embodiment of FIG. 4 represents an actuating device which adjusts perpendicular to the longitudinal or main course of the teeth 44 becomes. In addition, in this arrangement, the backdrop or the arrangement of the abutments 46 is arranged in the actuating device 45 , the teeth 44 themselves serving as bearing pins.

With reference to FIGS. 5A and 5B, various embodiments are shown, which serve as examples for a multitude of other arrangements metabolizable.

Fig. 5A shows the basic shape of a comb 51 and 1 with body member 55 and teeth 4, 5, as described with reference to the foregoing embodiments. The individual teeth are evenly spaced and laterally adjustable by appropriate force with the help of an appropriately designed actuating device.

FIG. 5B illustrates an embodiment, the tooth form of the individual teeth 52 may be varied in addition or alternatively to the above described options. For example, the tooth width can be varied if a tooth 52 as z. B. two-piece, overlying tooth is formed and the two tooth parts are moved laterally to each other. The smallest tooth thickness is provided in full overlay, and a particularly wide tooth thickness is achieved with teeth 52 lying next to one another. With further displacement, additional teeth 52 could also be formed.

A comparable arrangement can also be achieved with the exemplary embodiment from FIG. 5E, where two of the teeth 53 shown are arranged to be freely displaceable laterally on the body element, and thus can be pushed directly onto adjacent teeth. Correspondingly, wide teeth 53 are formed on the one hand and wide tooth gaps in between.

Fig. 5D shows the adjustment of the teeth 4, already described with reference to the first figures 5 through its bending.

It is also possible to use teeth 54 which can be added variably, as can be seen from FIG. 5C in comparison to FIG. 5A. When using such variable addable teeth 54 , a correspondingly adapted other actuating device with a larger number of abutments is preferably used. However, it is also possible to use an actuating device, the abutment or pin of which is partially unloaded when the number of teeth used is reduced.

In addition to the illustrated embodiments, embodiments are also possible in which an adjustment in the upward and downward direction is realized alternatively or in addition to the lateral adjustment of the teeth. Implementation can take place, for example, in that the abutments 12 shown in FIG. 1 have only a limited depth and varies over their length. As a result, the pins 11 of the actuating device 10 would rest on the bottom of the abutment 12 and accordingly, when the actuating device 10 was pushed forward or back, depending on the current depth of the abutment 12 , would not only adjust the teeth 4 , 5 laterally, but would also push them down to a different extent on a basis , This also results in a height adjustment of the teeth.
