Description

hair clipper

technical field

The invention relates to a hair clipper (electric clipper) according to the preamble of claim 1 and a hair cutting assembly for a hair clipper according to the preamble of claim 12 . the

Background technique

Such hair clippers and hair clipping assemblies are known from the prior art and are designed as shown, for example, in FIG. 5 . the

FIG. 5 shows a hair clipper 100 with a hair clipping unit 10 which can be arranged thereon and which essentially consists of a cutting comb 2 and a cutting blade 4 . The shearing blade 4 can be arranged on the hairdressing machine 100 in an oscillating motion relative to the shearing comb 2 via the driver 6 and is fastened there via the shearing comb 2 . The cutting comb 2 has a slider 52 on the hairdressing machine side, by means of which the cutting comb can be inserted into the guide 51 and is arranged on the hairdressing machine so as to be movable in the direction of the front side of the hairdressing machine in order to provide a trimming length adjustment. The shearing comb 2 is connected with the slider 52 through a fixing screw 53 . the

As shown in Figure 5, the shearing blade 4 has a gap 45 in the rear direction, that is, opposite to the cutting teeth 41 arranged on the front side of the shearing blade 4, and the driver 6 is embedded in this gap to drive the The movement of the moving part 6 is transmitted to the shearing knife 4 . In a high-quality, hairdressing assembly 10 as the invention relates, the cutting comb 2 and the shearing knife 4 are constructed as separate operable elements, rather than each other as is common in more favorable configurations of the hairdressing assembly. Fixed connection. the

It is common, especially in professional use of hair clippers, to open or remove the hair clipping components from time to time for cleaning or maintenance purposes in order to remove hair that has accumulated between the cutting comb and the shearing blades. To this end, as shown in FIG. 5 , the comb 2 is removed from the hairdresser 100 in the rearward direction, so that the shearing blades 4 are exposed. This removal—as shown in FIG. 5—can be performed by removing the shearing comb 2, but also by loosening the attachment screws. Care should be taken when removing the hair clipping unit that the clipper 4 as a separate part does not come loose from the hair clipper 100 and be damaged if dropped. the

In this exemplary embodiment, the shearing blade 4 is secured only by a slight clamping action between the slotted driver 6 and the inner side wall of the recess 45 . Especially if the hair clipper 100 is not kept in such a way that the shearing comb 2 and the shearing knife 4 are in a horizontal position when the shearing knife 2 is removed, then such a situation occurs that between the driver 6 and the gap 45 The clamping action between them is insufficient and the shearing knife 4 is thus loosened and falls to the ground. the

Contents of the invention

The object of the present invention is to improve the known hair-cutting unit in such a way that when the hair-cutting unit is removed, the shears are prevented from falling out. Furthermore, a possibility of retrofitting this function should be provided for hairdressing machines already in use. the

This object is solved by a hair clipper with the features of claim 1 and by a hair clipper assembly with the features of claim 12 . the

Advantageous solutions are the technical solutions of the dependent claims. the

The hairdressing machine according to the invention has a drive and an exchangeable haircutting unit consisting at least of a cutting comb and a cutting knife. The shearing knife can be driven to vibrate relative to the shearing comb through a driver arranged on the driving device. According to the invention, the hair clipper is characterized in that a holding device is provided on the driver, by means of which holder the scissors are secured to the driver in a non-losable manner. the

It is achieved in this way that when removing the hair cutting unit or the cutting comb, the cutting blade is fixed on the hair cutting machine and thus cannot fall to the floor, said cutting blade is preferably designed to be operable separately from the cutting comb separate parts. This prevents the clippers from being damaged by falling, thus extending the service life of the hair cutting unit overall. the

In order to be able to avoid major modifications to the conventional components in existing hairdressing machine types, the holding device and the driver are designed as separate devices. In this way, existing hair clipper types can be retrofitted with a holding device which can be fastened to the driver without further modifications to the hair clipper. the

An advantageous embodiment of the holding device is obtained if the holding device has at least one section with which the holding device overlaps the shearing blade. It is achieved in this way that the clippers are held on the hairdressing machine by this overlapping section, so that loosening of the clippers can be avoided. Simultaneously, it is achieved by this solution of the holding device that when the shearing blade moves parallel to the overlapping area, the shearing blade can be removed from the hairdresser and thus replaced. the

A particularly simple solution is achieved when the holding device engages in the recess of the shearing blade and overlaps this recess at the front and/or at the sides. It is common for shearing knives of the prior art to have recesses in which the driver engages in order to transmit the oscillating movement to the shearing knives. Accordingly, a retaining device arranged on the driver can engage in this recess and overlap this recess in the front and/or side direction to fix the shears in order to hold the shears to the driver and thereby cut the hair on board. the

A particularly simple arrangement of the retaining device on the driver is achieved if the retainer surrounds the driver in a form-fitting manner. Such a form-fitting connection can be designed, for example, as a snap-in connection, so that the holding device is shaped in such a way that it can be clamped or snapped onto the driver. the

A cost-effective solution is achieved if the holding device is made of plastic, for example configured as a plastic molded part. the

Alternatively, the holding device can consist of metal, for example configured as a sheet metal bend or as a profile spring. the

It is possible, for example, to retrofit the delivered hairdressing machine type in the following manner: a hairdressing assembly for the hairdressing machine is provided, which has a cutting comb and a shearing knife, wherein additionally a holding device is provided for The shears are held securely on the driver of the hairdressing machine. the

Detailed ways

FIG. 1 shows a hairdressing machine 100 according to the invention with a haircutting unit 10 comprising a cutting comb 2 and a cutting blade 4 . The shearing knife 4 can vibrate relative to the shearing comb 2 through a driver 6 connected to the driving device of the hairdresser 100, such as a vibrating armature motor, so that the hair between the comb teeth 22 and the knife teeth 41 It is cut by the relative movement between the shear blade 4 and the shear comb 2 . The shearing blade 4 has a recess 45 into which the driver 6 engages. Furthermore, a holding device 7 is arranged between the driver 6 and the shears 4 , which is fastened to the driver 6 and overlaps the shears 4 at the front and at the sides in the region of the recess 45 . In this way, as shown in FIG. 1 , the clippers 4 are securely fastened to the hair clipper 100 when the hair clipping unit 10 is removed, so that the clippers 4 are prevented from falling out. the

FIG. 2 a shows a perspective view of the holding device 7 of FIG. 1 . According to the exemplary embodiment in FIG. 2 , the holding device 7 is designed as a bent sheet metal part and has a fastening section 75 for fastening the holding device 7 to the driver part 6 . As shown in FIG. 2 b , the fastening section 75 is designed in such a way that it encloses a section of the driver 6 in a form-fitting manner and can be slipped or clipped onto this section from a free end of the driver 6 . For this purpose, the holding device 7 has latching side walls 79 on the front side of the fastening section 75 , which engage a section of the driver 6 from behind and thus prevent the holding device 7 from detaching from the driver. 6 slip and loose. In order to secure the shears 4 to the hair clipper 100 , the holding device 7 has a projection 71 and a flank 73 formed on the projection 71 . the

As can be seen in FIG. 2 b , the driver 6 engages with its front end in a recess 45 of the shearing blade 4 and enables the shearing blade 4 to be driven. The projections 71 and the flanks 73 of the holding device 7 overlap the shearing blade 4 not only at the front but also at the sides in the region of the recess 45 so that the shearing blade 4 cannot be detached from the hair clipper 100 as shown in FIG. 1 . the

The principle of action of the holding device 7 can be seen particularly clearly from FIG. 2c. It can be seen particularly clearly in this figure how the projection 71 of the holding device 7 overlaps the shearing blade 4 . But this solution of holding device 7 just is possible under the following situation, that is, when shearing knife 4 is on the knife tooth 41 on the front side, and on the rear side on a sliding strip that extends parallel to knife tooth 41 43 rests against the shearing comb 2 and thus ensures sufficient space for engaging the holding device 7 in the intermediate space between the knife teeth 41 and the sliding strip 43 . the

Flanks 73 formed on the side enable additional fixing of the shears 4, so that additionally the sliding strip 43 formed on the rear side of the shears 4 with which the shears 4 slide on the shearing comb 2 has to be overcome . the

FIG. 3 shows a perspective view of another embodiment of the holding device 7 . In this exemplary embodiment, the retaining device 7 is designed as a so-called profile spring, ie as a retaining clip made of spring steel. The holding device 7 also has, like the holding device 7 shown in FIG. 2 , a rear fastening section 75 which is designed to surround the driver 6 of the hair clipper 100 . According to this embodiment, a bend is provided in the profile spring as a latching element 79 , which engages in the recess 45 of the driver 6 and thus fixes the holding device 7 on the driver 6 . On the holding device 7, an arc-shaped clip 77 is provided on the front side, which overlaps the scissors 4 in the region of the recess 45 similarly to the projection 71 and the flanks 73 and thus prevents the clipper from being removed from the hair clipper. 100 loose. the

FIG. 3b shows the arrangement of the shearing knife 4 on the driver 6 by means of the profile spring shown in FIG. 3a. The embodiment of the retaining device 7 as a profile spring has the advantage that the mounting of the retaining device 7 on the driver part 6 is made simpler by virtue of the elastic properties of the spring steel used for producing the profile spring. the

As in the configuration of the holding device 7 of FIGS. 1 and 2 , the bow clip 77 also additionally secures the shears 4 against falling out in such a way that when removing the shears 4 it is necessary to overcome the position provided on the The sliding slat 43 of shearing knife 4 rear sides. the

4a and 4b show another embodiment of the holding device 7 as a bent sheet metal part. Like the holding device 7 in FIGS. 1 and 2 , the holding device 7 according to FIG. 4 has a rear fastening section 75 which is positively adapted to the driver 6 of the hairdressing machine 100 . In order to fasten the holding device 7 to the driver 6 , in this case also a snap connection is provided, which is formed by means of two snap side walls 79 which are viewed from the rear A section of the driver 6 is engaged. In this exemplary embodiment, the front section of the holding device 7 , which is used to fasten the shears 4 , is only designed as a projection 71 . In the present exemplary embodiment, the flanks 73 which are additionally arranged laterally to the projection 71 in FIGS. 1 and 2 are not provided. By not providing the side wings 73, the shearing knife 4 is easier to take off, because there is no need to overcome the sliding strip 43 that is arranged on the rear side of the shearing knife 4 as additional resistance. the

Furthermore, the holding device 7 of all embodiments can be made of plastic with suitable properties. the
