Description

[0001] The present invention relates to an adjustment device for a hair cutting device according to the preamble of claim 1.

[0002] Hair clippers that achieve the cutting action by moving blades back and forth have been known for a long time. With such hair clippers, the distance within a set of blades—that is, the distance between a moving cutting part (blade) and a stationary cutting part (comb)—can be individually adjusted by the end user to achieve the desired result.

[0003] In a hair clipper with a movable blade and a stationary blade (i.e., a blade that is fixed to the clipper and cannot move horizontally and / or vertically), the movable blade moves laterally relative to the stationary blade when the clipper is operated. The movable and stationary blades can be adjusted relative to each other in a direction perpendicular to the direction of their back-and-forth movement. Similarly, in a hair clipper with two movable blades, these blades also move relative to each other and can be adjusted in a direction perpendicular to their back-and-forth movement.

[0004] The distance between the two cutting blades is adjusted by loosening fasteners by hand with a tool before using the clippers. These fasteners are typically screws located on the lower part of the clippers, connecting the movable blade to a guide held by the stationary blade. Completely loosening or loosening the screws sets the blades to the desired distance. After adjusting the distance, the screws must be tightened sufficiently to prevent them from loosening during subsequent use of the clippers.

[0005] The "barber trend" that has emerged in recent years continues and is increasingly influencing traditional hairdressing. For certain types of precise hair cutting and trimming operations, such as outlining details or cutting lines or patterns into a person's hair or hairline—whether facial, scalp, or body hair—it is desirable to set the distance between the stationary hair blade and the cutting blade resting on it as small as possible.

[0006] For certain applications of hair cutting devices, such as outlining details or cutting lines or patterns into a person's hair, as well as cutting the edge of a person's hairline, there is an increased demand for extremely short cutting lengths.

[0007] The teeth of the moving blade are typically offset from the teeth of the stationary blade to prevent cutting the skin of an animal or person whose hair or beard is being trimmed. To avoid unwanted skin damage, the moving blade should be adjusted before the cutting process so that it is offset from the stationary blade by a very small distance.

[0008] It is therefore desirable to adjust the hair cutting device before use in such a way that the distance between the stationary hair blade and the cutting blade is set and held as small as possible in order to achieve extremely short cutting lengths with a conventional hair cutting device.

[0009] Until now, such adjustments to the distance between the moving and stationary hair blades, known in the industry as zero-overlap adjustment, were made by a professional hair clipper user either by eye or with the aid of adjustment devices. This required completely removing or disassembling the cutting unit for adjustment, and then, after the adjustment had been made by eye, reinstalling it in the hair clipper.

[0010] However, such adjustments to the distance between the moving and stationary hair blades must be made very precisely and require a certain level of technical expertise that not every user of hair clippers, and especially not of professional hair clippers like a hairdresser, possesses. An incorrect adjustment of the two cutting parts can lead to damage to the skin of the person or animal being treated.

[0011] Therefore, there is a need for an adjustment device that allows the end user to consistently adjust the cutting sets, including to extremely small distances between the cutting blades for precise hair cutting operations.

[0012] The object of the present invention is therefore to provide an adjustment device for a hair cutting device which enables a user to easily and reproducibly adjust the cutting sets to a maximum short distance from each other, so that a maximum short cutting length can be achieved safely and with the least possible effort, thereby minimizing the risk of skin injuries.

[0013] This problem is solved according to the invention by an adjustment device for a hair cutting device with the features of claim 1.

[0014] Preferred embodiments of the present invention are set forth in the dependent claims.

[0015] To enable a better understanding of the adjustment device according to the invention for a hair cutting device, the terms and definitions used here are explained in more detail below.

[0016] The upper, movable cutting element is referred to as the "blade," and the lower, larger cutting element is referred to as the "comb" or simply "comb." The combination of blade and comb, including any attachments, is called the "cutting set." The device without the cutting set is referred to as the "hair clipper."

[0017] Furthermore, the "blade-comb distance" to be set using the adjusting device according to the invention is defined as the distance from the shearing comb tooth tip to the shearing blade tooth tip. The shortest distance from the shearing blade tip to the shearing comb bevel is referred to as the "cutting length".

[0018] A so-called "linear guide" between the shear blade and the guide piece provides geometrically constrained guidance for the blade. This ensures that the blade-comb distance and parallelism remain unchanged in both the on and off positions.

[0019] With radial blade movement, however, the cutting blade moves in a circular arc. The blade-comb distance and the parallelism in the on and off states change continuously. In the off state, the blade is always positioned on the right or left side due to force applied inside the housing of the hair clipper.

[0020] A hair-cutting device comprises a housing and a cutting set permanently attached to the housing. The cutting set consists of a shearing blade, which includes blade tips, and a shearing comb, which includes comb tips, connected to it. The shearing comb is detachably connected to the shearing blade, and thus also to the hair-cutting device, by means of connecting elements such as screws.

[0021] The adjustment device according to the invention for such a hair cutting device is characterized in that it is dimensioned in such a way that it can receive and hold the shearing comb, so that after loosening or partially releasing the connecting elements, the shearing comb together with the adjustment device can be moved relative to the device housing, so that a distance between the blade tips and the comb tips can be defined.

[0022] Thus, the device according to the invention makes it possible to adjust the knife tips and comb tips to a maximum short distance from each other without having to disassemble and remove the entire cutting set from the device housing for the adjustment.

[0023] This significantly minimizes the risk of injury to the operator when removing the shear blade. Furthermore, the distance is adjusted simply yet precisely, enabling the shortest possible cutting length with minimal effort. Thus, a so-called zero-overlap setting can be performed very precisely with the adjustment device according to the invention, without this adjustment depending on the user's skill and experience.

[0024] Furthermore, the adjustment device according to the invention allows for a very quick and therefore time-saving adjustment of the knife tips and comb tips of the cutting set, which is particularly important in the professional use of hair cutting devices.

[0025] Preferably, the shearing comb is positioned with its comb tips against the adjustment device, which is dimensioned accordingly to securely receive and hold the shearing comb so that the adjustment can be carried out.

[0026] Preferably, the adjusting device according to the invention, together with the shearing comb, is positioned in relation to the shearing blade such that the adjusting device rests in a defined position against the blade tips of the shearing blade. Thus, a defined, preferably minimal, distance between the blade tips and the comb tips is achieved, preferably by shifting the loosened parts of the cutting set relative to each other, without having to separate them and insert them individually into the adjusting device.

[0027] It is considered particularly preferred if the adjusting device is essentially box-shaped and comprises a base, a front wall extending perpendicular to the base, and at least one side wall extending perpendicular to the base for the defined reception and retention of the shearing comb and the associated shearing blade. The base is dimensioned such that its dimensions correspond to the external dimensions of the cutting set and, in particular, the shearing comb. Thus, the cutting set can be securely received and retained in the essentially box-shaped device.

[0028] Preferably, the base of the adjusting device according to the invention has at least one recess that corresponds to the connecting elements of the shearing comb in order to loosen or release the connecting elements of the shearing comb when the shearing comb and the shearing blade are fully received into the adjusting device.

[0029] The front wall of the adjusting device has an inwardly projecting projection at its front end, furthest from the hair-cutting device. This projection allows for setting a specific offset distance between an edge of the shearing comb and an edge of the shearing blade, with the projection acting as a stop for the edge of the shearing blade. When inserted, the edge of the shearing comb rests beneath this stop. In this way, the distance between the shearing blade edge and the shearing comb edge is precisely adjusted.

[0030] A preferred embodiment of the present invention provides that the projection is formed to protrude at an upper edge of the front wall, so that it forms a stop for the shearing blade, wherein the shearing comb lying under the shearing blade is arranged under the stop in the assembled state of the cutting set.

[0031] According to a preferred embodiment, the stop can extend downwards, tapering towards the bottom of the adjusting device and forming a slope.

[0032] The projection can also be rounded or shaped like a ridge. It is important that the projection or stop extends along an inner side of the front wall, so that it aligns with the edge of the shear blade. The projection can run continuously along the front wall or have breaks in its direction of extension, allowing the blade to rest on sections of it.

[0033] To securely lock the shearing comb and blade to the adjustment device, preferably one or more rear snap hooks are provided, positioned opposite the front wall. This prevents the cutting set from being unintentionally detached from the adjustment device, allowing for safe and convenient adjustment by the user and significantly minimizing the risk of injury.

[0034] Preferably, a rear snap hook is provided opposite the front wall of the adjustment device to lock the shearing comb and shearing blade in place when they are inserted into the device as a single unit. This ensures secure retention of the cutting set in the adjustment device. The snap hook can also be located, for example, on one or both side walls.

[0035] Preferably, the adjusting device according to the invention has two side walls extending parallel to each other, which are connected to the front wall and have lateral guides on the inside for the parallel alignment of the shearing comb and the shearing blade to each other, wherein gripping surfaces are provided on the outside of the side walls in order to be able to hold the device securely with only one hand.

[0036] Another preferred embodiment provides that the aforementioned internal lateral guides are designed as spring tongues, so that they can easily align the shearing comb and the shearing blade parallel to each other when these are inserted into the adjusting device.

[0037] Another preferred embodiment of the present invention provides that the adjusting device comprises a base, a front wall extending perpendicular to the base, and a rear wall extending perpendicular to the base for receiving and holding the shearing comb and the associated shearing blade, wherein lateral limits are provided for correctly positioning the shearing comb and the associated shearing blade and for holding the adjusting device in place, and wherein the base extends approximately midway between the front wall and the rear wall. The front wall and the rear wall extend upwards and downwards above the base, so that the adjusting device can be used on both sides for two different cutting sets or different hair cutting devices.

[0038] Preferably, the adjusting device has a first base and a second base extending parallel to each other and connected laterally by side walls arranged parallel to each other. The adjusting device has a front wall which is connected to the side walls and is arranged substantially perpendicular to them. The first and second bases extend upwards from the front wall at an angle of approximately 50° towards a hair cutting device to be inserted. The front wall preferably has a projection on each of its surfaces corresponding to the two bases for adjusting the cutting blade relative to the cutting comb.

[0039] Preferably, according to the above embodiment, the front wall has projections at an upper and a lower end for adjusting the shearing comb and the shearing blade relative to each other, wherein the projections extend elongatedly, and wherein the rear wall is curved inwards at an upper and a lower end to hold the shearing comb and the shearing blade in the adjusted position relative to each other. The projections of the rear wall are dimensioned to receive and retain two different cutting sets.

[0040] It can also be provided that the bottom wall is formed in two parts, with the two parts running parallel to each other in the longitudinal direction of the adjustment device and being firmly connected to each other, and extending upwards and downwards at their two opposite ends, so that they define a box.

[0041] According to a further embodiment of the present invention, the adjusting device has a base, a side wall, a front wall and a rear wall, such that these define a laterally open box into which the hair cutting device with the built-in cutting set can be inserted laterally, wherein the front wall has a lateral projection which includes a stop for adjusting the shear blade relative to the shear comb.

[0042] Another preferred embodiment provides that the base is designed as a rib and dimensioned in such a way that it can be guided into a recess provided between the shearing comb and the shearing blade in the installed state, wherein the positioning of the shearing blade relative to the shearing comb is carried out via the recess.

[0043] Preferably, the adjusting device has a side wall that is rigidly connected to the rib-like base and extends perpendicularly from it in the longitudinal direction of the shearing comb. The adjusting device also has a rear wall that is connected to the side wall at a substantially right angle, so that the adjusting device laterally encompasses the cutting set and is suitable for adjusting the shearing blade and the shearing comb. It is considered particularly preferred if the rear wall does not enclose the entire back of the shearing set, thus ensuring free access to the connecting elements of the shearing set.

[0044] The adjusting device according to the invention can be designed in one piece, or in two parts or in multiple parts.

[0045] Preferably, a two-part adjusting device has a first, inner part which forms a receptacle for the cutting set and holds it under tension, and a second, outer part which holds the tension, wherein the first part and the second part are displaceable relative to each other in order to press the shearing blade into a central position.

[0046] In a two-part adjusting device, the two parts can be manufactured as separate parts and connected to each other before use of the adjusting device, or they can be manufactured as separate parts that are designed as a unit, with the two parts being slidable into each other.

[0047] Preferably, the first part of the two-part adjusting device has a base, a front wall and two side walls which are connected to the base and each of which includes a spring tongue on their parts adjacent to the front wall for fixing the shear blade in a central position.

[0048] Preferably, the first part and the second part of the respective front wall have corresponding recesses opposite each other, which are connected to the connecting elements of the shearing comb.

[0049] A particularly preferred embodiment of the two-part adjusting device provides that the side walls of the first part each have a longitudinally extending web on their outer sides adjacent to the second part for the axial guidance of the second part, wherein the second part is designed such that it has corresponding side walls, each of which has an elongated recess or a groove for receiving the respective adjacent web.

[0050] Preferably, the second part of the two-part adjusting device has a base on whose inner surface, opposite the shearing comb, a projection is provided for locking the shearing comb into place.

[0051] Particularly preferably, a recess for receiving a tool is provided in the first and / or second part of the adjusting device, wherein the tool can be grasped and removed in a fully closed or in an open position of the adjusting device in order to at least partially release the connecting elements of the shearing comb.

[0052] Preferably, the recess for the tool provided in the first and / or second part is designed as a continuous opening, which is circular, cross-shaped and polygonal in shape and is suitable for securely receiving differently shaped tools.

[0053] It is considered particularly advantageous that the adjustment device according to the invention for a hair clipper can be used not only for cutting sets in which the blade and comb are positioned relative to each other by means of connecting elements and can be removed from the hair clipper, but also for cutting sets in which the blade and comb are positioned relative to each other only via the handheld device. In this case, the cutting set does not need to be removed from the hair clipper for adjustment.

[0054] The adjustment device according to the invention for a hair cutting device can also be used to remove the shearing comb for cleaning the hair cutting device and to properly reassemble it on the hair cutting device.

[0057] Preferred embodiments of the present invention are explained in more detail below with reference to the drawings. Identical and equivalent technical features are designated with the same reference numerals in the figures.

[0058] To explain the effect of the adjustment device according to the invention for a hair cutting device, reference is made to the Fig. 1a, Fig. 1b and Fig. 2a, Fig. 2b referred to which two hair-cutting devices 20 with the respective cutting sets 24 represent.

[0059] In Fig. Figure 1a shows a hair cutting device 20 in a top view. The hair cutting device 20 has a device housing 22 and a removable cutting set 24. The cutting set 24 consists, in a manner known per se, of a shearing blade 26 and a shearing comb 28 located underneath it, corresponding to and connected with the shearing blade 26, wherein in this embodiment the cutting set 24 is a cutting set with a radial blade guide.

[0060] With radial blade guidance, the shear blade 28 moves in a circular arc. The blade-comb distance, which is in Fig. As shown in Figure 1a, the parallelism in the on and off states changes continuously during radial blade guidance. In the off state, the shear blade 28 is always positioned on the right or left side by a spring force acting upon it.

[0061] The in Fig. The hair cutting device 20 shown in Figure 2a differs from the one shown in Figure 2a. Fig. 1a shown by the linear knife guide. Due to the linear guide on the cutting set 24, the knife-comb distance and the parallelism remain constant in the on and off states.

[0062] The cutting blade-cutting comb distance of the in the Fig. 1b as well as the one in the Fig. The enlarged section of each cutting set 24 shown in Figure 2b is almost 0 mm. For some applications of a hair cutting device, it is important that there is practically no gap between the edges of the cutting blade and the cutting comb, so that the cutting edges are essentially overlapping.

[0063] With a linearly guided knife, as in Fig. As shown in 2a, it is assumed that the shearing blade 26 and the shearing comb 28 are already parallel to each other.

[0064] In the case of a radially guided shear blade, as in Fig. As shown in Figure 1a, an angular offset occurs depending on the position in which the blade comes to rest. Therefore, in order to bring the shearing blade 26 into a central position, the shearing blade 26 and the shearing comb 28 must be positioned parallel to each other. In doing so, the blade tips 30 and the comb tips 32 are aligned as shown in Figure 1a. Fig. 1a shown, covered, whereby a minimal distance between them can be achieved.

[0065] Therefore, it is necessary that the adjustment devices are adapted and suitable for the respective designs of the cutting set of different hair cutting devices.

[0066] In Fig. Figure 3 shows a perspective view of an adjustment device 10 according to a first embodiment of the present invention. The adjustment device 10 is essentially box-shaped and has a base 12, a front wall 16 extending perpendicular to the base 12, and two side walls 18 extending perpendicular to the base 12.

[0067] The adjusting device 10, thus designed, is dimensioned such that the dimensions of the base 12 and the walls extending upwards perpendicular to the base 12 are suitable for accommodating a cutting set 24 of a hair cutting device 20, as shown in Fig. As shown in 1a, the shearing comb, with the shearing blade firmly attached to it, is inserted into the box-shaped setting device 10 and moved forward towards the front wall 16 until the comb tips rest against the front wall 16.

[0068] The two side walls 18 have elongated guides 48 at their upper edge, which provide a guide surface for inserting the cutting set of the hair cutting device. The elongated guides 48 are mirror-symmetrical, ensuring parallelism when inserting the cutting set into the adjustment device 10 and thus guaranteeing that the lower surface of the cutting comb 28 lies close to the base 12 of the adjustment device 10.

[0069] To securely receive the shearing comb into the adjusting device 10, a snap hook 42 is provided, which in this embodiment extends parallel to the front wall 16 approximately in the middle and is only integrally connected to the base 12 of the adjusting device 10.

[0070] The base 12 of the adjusting device 10 has two recesses 14 which are dimensioned such that they are provided with connecting elements, usually screws, which are provided on the lower part of the cutting set for connection to the device housing of the hair cutting device.

[0071] This allows the connecting elements to be easily loosened or released without having to remove and separate the entire cutting set from the device housing. Therefore, the distance between the blade tips and the comb tips can be adjusted quickly and safely.

[0072] To precisely define the distance, the front wall 16 is dimensioned in the vertical direction such that the comb tips extend to a lower edge of the projection 38. The knife tips, which lie directly on the comb tips, extend to the projection 38, so that the width of the projection 38 defines the distance between the knife tips and the comb tips.

[0073] By loosening the connecting elements in the adjusting device while the cutting set is inserted, a very precise adjustment of the two cutting elements relative to each other can be achieved. After the adjustment process, the screws can then be tightened again, so that the cutting set, together with the entire hair clipper, can be removed from the box-shaped adjusting device 10.

[0074] The in Fig. 3 Adjustment device 10 has grooved grip surfaces 46, which are formed on the respective outer sides of the side walls 18 to facilitate the insertion of the cutting set into the adjustment device 10 and the removal of the cutting set from the adjustment device 10.

[0075] In Fig. Figure 4 shows a perspective view of an adjustment device 10 according to a second embodiment of the present invention. This embodiment differs from the one shown in Figure 4. Fig. 3 shown, by the fact that the side walls 18 are not continuous and are not connected to the front wall 16. The side walls 18 extend vertically with respect to the base 12 of the adjusting device 10 and each have a spring tongue 50 in the direction of the front wall 16, which serve to fix the shear blade in the central position.

[0076] Furthermore, in this embodiment the snap hook 42 is shorter than in the one described in Fig. The embodiment shown in Figure 3 is designed such that the recesses 14 are correspondingly larger, which increases accessibility to the connecting elements of the cutting set and therefore facilitates operation. By providing spring tongues 50, which serve to fix the shear blade in the central position, this adjusting device 10 can also be suitable for hair cutting devices in which the blade movement is radial.

[0077] In Fig. Figure 5a shows a perspective view of an adjustment device 10 according to a third embodiment of the present invention.

[0078] The adjusting device 10 according to the third embodiment according to the invention is characterized in that it is box-shaped and has a rear wall 44 which is connected to the side walls 18 and to the bottom 12.

[0079] The front wall 16 is connected only to the base 12 and is elastically designed so that it acts as a kind of snap hook. The front wall 16 is dimensioned such that it corresponds to the cutting set and laterally limits it, so that when the cutting set, together with the device housing 22, is inserted into the adjusting device 10, the elastic front wall 16 acts as a snap hook and, after loosening the connecting elements (not shown here), the shearing blade 26 can be moved relative to the shearing comb 28. The edge 34 of the shearing blade 26 and the edge 36 of the shearing comb 28 rest against the inner wall of the front wall 16, as shown in Fig. 5c, which shows a sectional view along line DD from Fig. 5b is shown. Thus, a zero-overlap setting can be easily implemented.

[0080] As in the Fig. As shown in Figures 5a to 5c, the front wall 16 is indeed formed in one piece, but it has a lower elongated section which is connected to the base 12 and extends essentially at right angles upwards, and an upper section firmly connected to it, which is shorter than the lower section and inclined outwards.

[0081] In order to insert the device housing 22 together with the cutting set 24 into the adjusting device 10 and hold it securely until the adjustment is carried out, the cutting set 24 is inserted from above into the box-shaped adjusting device 10 and pressed downwards using force until the edge 36 of the shearing comb 28 rests against the inner wall.

[0082] In Fig. Figure 5a shows two recesses 14 in the base 12 of the adjusting device 10, which are dimensioned such that they correspond to the connecting elements of the cutting set, so that these can be easily loosened or detached when the hair cutting device 20 is connected to the adjusting device 10.

[0083] As shown in the sectional view of Fig. As can be seen in Figure 5c, in this embodiment the rear wall 44 is designed such that a receptacle for the rear part of the shearing comb 28 is provided, so that the shearing comb 28 can be encompassed by the rear wall 44 and thus connected without play.

[0084] Thus, the edges 34 and 36 of the shearing blade 26 and the shearing comb 28 can be easily adjusted without having to separate them.

[0085] Thus, the hair cutting device 20 can be connected to the adjusting device 10 during the adjustment process, as shown in Fig. 6 is shown.

[0086] In Fig. Figure 7a shows a fourth embodiment of the adjusting device 10 according to the invention in perspective. The adjusting device 10 is designed such that it has a base 12, as in the other embodiments described above, a side wall 18 and a rear wall 44.

[0087] As in the Fig. As shown in Figures 7a to 7c, a support surface 11 is provided so that the adjusting device 10 can be supported on a flat surface, wherein the base 12 and the side wall 18 and rear wall 44, which are connected to it and formed in one piece, extend upwards at an angle of approximately 50° from the flat support surface 11, so that when the hair cutting device 20 together with the cutting set 24 is inserted laterally into the adjusting device 10, the hair cutting device 20 extends substantially perpendicular to the support surface.

[0088] As in Fig. As shown in 7a, the base 12 has two recesses 14 which correspond to the connecting elements of the cutting set 24, so that the connecting elements can be loosened or released when the cutting set 24 is fully inserted into the adjusting device.

[0089] The front wall 16 is designed such that it has a projection 38, as shown in the Fig. 7a and Fig. 7b shown. The ridge tips extend to a lower edge of the projection, which corresponds to the ground 12.

[0090] The blade tips of the shearing blade 26, which lie directly on the comb tips of the shearing comb 28, extend to the projection 38, so that the width of the projection 38 defines the distance between the blade tips and the comb tips, as shown in Fig. 7b shown.

[0091] As in Fig. As shown in Figure 7a, the side wall 18 is designed such that it has a projection 19 towards the front wall 16. The projection 19 extends further towards the open end of the adjusting device 10, through which the cutting set is inserted into the adjusting device 10. Thus, the shearing comb 28 can be fully inserted into the adjusting device 10 up to the inner surface of the side wall 18.

[0092] The projection 19, which is formed on the upper part of the side wall 18, serves as a limit for the shearing blade 26 in the area of ​​the blade tips, so that this embodiment is suitable for hair cutting devices with both a radial and a linear blade guide.

[0093] In the Fig. Figures 8a to 8d show a fifth embodiment of the adjusting device 10 according to the invention.

[0102] The side walls 18 are rigidly connected to two parallel bases 12, 12' of the adjusting device 10, as shown in the Fig. 10a, Fig. 10c and Fig. Figure 10f shows that the two bases 12, 12' are inclined relative to the front wall 16, so that when the hair cutting device 20 is inserted together with the cutting set into the adjusting device 10, the hair cutting device 20 is essentially perpendicular to the adjusting device 10, as shown in the Fig. 10d and Fig. 10g is shown, arranged.

[0103] In Fig. 10c the shearing comb 28 together with the shearing blade 26 is inserted into the first opening of the adjusting device 10, so that the shearing comb 28 is guided along the bottom 12 to the adjacent front wall 16, as shown in Fig. 10b is shown, and the adjustment of the distance between the tips of the shearing comb 28 and the shearing blade 26 is made after loosening the fastening elements.

[0104] It should be noted that in Fig. Figure 10b shows only the openings in the shearing comb 28 provided for the fastening elements. The first opening in the adjusting device 10 is suitable for adjusting the distance between the tips of the shearing comb 28 and the shearing blade 26 of a hair cutting device with radial blade guidance.

[0105] In Fig. 10f, which shows a cross-sectional view along line BB of Fig. Figure 10e shows that the cutting set is inserted into the second opening of the adjusting device, with the underside of the shearing comb 28 resting against the base 12' and the adjustment of the distance between the tips of the shearing comb 28 and the shearing blade 26 is suitable for a hair cutting device with linear blade guidance.

[0106] The Fig. Figures 11a-11f show the adjusting device 10 according to a further embodiment of the present invention.

[0107] As in Fig. As shown in Figure 11a, the adjusting device 10 is constructed such that it has a base 12 which is connected to a front wall 16, as in the other embodiments; however, the base 12 is connected to the front wall 16 essentially in the middle. At the rear end of the base 12, it spreads into two parts, upwards and downwards, so that each part has a rear wall 44. Laterally, the base 12 is connected to two side walls 18 on each side, which extend approximately midway upwards and downwards from the base 12 and serve as lateral boundaries for the cutting set and as gripping surfaces for the adjusting device 10.

[0108] The in the Fig. 11b and Fig. The adjusting device 10 shown in Figure 11c is suitable for adjusting a hair cutting device with a radial blade guide. Fig. Figure 11b shows the adjusting device 10 from the front. The edge 34 of the shearing blade 26 is in the central position, as shown in Fig. 11b shown.

[0109] In Fig. 11c is a sectional view along line FF of Fig. Figure 11b shows how the shearing blade 26 is adjusted in relation to the shearing comb 28. In the Fig. 11c and Fig. Figure 11d shows the dual use of the adjusting device 10, namely for a hair cutting device with radial blade guidance, as in Fig. 11c shown, and for a hair cutting device with linear blade guidance, such as the Fig. The example shown in Figure 11d. The two uses of the adjusting device differ in the design of the respective projection formed on the front face 16 or 16', which is suitable for adjusting the shearing blade 26 relative to the shearing comb 28.

[0110] This embodiment has the advantage that the adjusting device is doubly usable, namely for adjusting hair cutting devices with a radial blade guide, as in the Fig. 11b and Fig. 11c shown, and also for adjusting hair cutting devices with a linear blade guide, as in the Fig. 11a, Fig. 11d, Fig. 11e and Fig. shown in 11f. It should be noted that the device is designed according to the Fig. 11b and Fig. 11c the lower of the in Fig. 11a represents the adjustment device shown.

[0111] In the Fig. Figures 12a-12h illustrate an adjustment device according to a ninth embodiment of the present invention. The adjustment device 10 is constructed in two parts and comprises a first part 52, as shown in the Fig. 12b and Fig. 12c shown, and a second part 54, as in the Fig. 12d and Fig. 12e is shown. The first part 52 is dimensioned such that it can be inserted into the second part 54 and held in place by means of a snap connection.

[0112] As in Fig. As shown in Figure 12b, the first part 52 is similar to the one-piece embodiment according to Fig. 4 constructed and has a base 12 which is connected to two opposing and parallel side walls 18.

[0113] A front wall 16 is provided on the front part of the base 12, which extends upwards, essentially perpendicular to the base 12 and has a projection 38, which in this embodiment is formed with interruptions on the upper part of the front wall 16.

[0114] The projection 38 serves as a stop surface for the corresponding tip of the shearing blade 26 in the inserted state, as shown in Fig. 12h shown. The projection 38 is spaced from the base 12 and provides a stop surface for the tips of the shearing comb 26, as in Fig. 12h shown, depicted.

[0115] The base 12 of the first part 52 of the adjusting device 10 has a recess 68 approximately in the center, which in this embodiment defines a stop 70 opposite the front wall for the engagement of the second part 54.
