Description

The present invention relates to an adjustment device for a hair clipper according to the preamble of claim 1.

Hair cutting devices in which the cutting effect is achieved by moving blades back and forth have been known for a long time. In such hair clipping devices, the distance in a set of blades, i.e. the distance between a movable cutting part (blade) and a stationary cutting part (comb), can be individually adjusted by the end user in order to be able to achieve the desired result.

In a hair clipper with a movable blade and a stationary blade, i.e. a blade that is fixed to the hair clipper and cannot be moved in the horizontal and/or vertical direction, the movable blade moves laterally relative to the stationary blade when the hair clipper is actuated back and forth. The movable and stationary blades are adjustable relative to each other in a direction perpendicular to a reciprocating direction of movement. Also, in a hair clipper having two movable blades, these blades reciprocate relative to each other and can be adjusted in a direction perpendicular to a reciprocating direction.

The distance between the two hair cutting parts is adjusted by loosening fastening elements with a tool by hand and before using the hair cutting device. The fasteners are typically screws located on a lower portion of the clipper that connect the movable blade to a guide held by the stationary blade. Complete loosening or loosening of the screws sets the blades to the desired spacing. After adjusting the distance, the screws must be tight enough so that they cannot loosen when the hair clipper is subsequently used.

The "barber trend" that has emerged in recent years is continuing and increasingly influencing the classic hairdressing trade. For certain types of precise Hair cutting and trimming operations, such as outlining detail or cutting lines or patterns into a person's hair or the edge of a person's hairline, whether facial, scalp or body hair, it is desirable that the distance between the so-called stationary hair blade and the cutting blade lying on it is set as small as possible.

For certain applications of hair clippers, such as outlining detail or cutting lines or patterns in a person's hair, and trimming the edge of a person's hairline, there is an increased demand for extremely short cut lengths.

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

Thus, it is desirable to adjust the hair clipper prior to use such that the distance between the stationary hair blade and the trimming blade is adjusted and maintained as small as possible in order to achieve extremely short trimming lengths with a conventional hair clipper.

Heretofore, such adjustments of the distance between the movable and stationary hair blade, known in the art as zero-overlap adjustment, have been made by a professional user of hair clippers with the naked eye or with the aid of adjustment devices. Previously, the cutting set had to be completely removed or dismantled for adjustment and then, after the adjustment had been made by eye, reinstalled in the hair clipper.

However, such adjustments of the distance between the movable and the stationary hair blade should be made very precisely and require a certain technical know-how, which not every user of hair cutting devices and in particular of professional hair cutting devices, such as a hairdresser, bring with them can. However, incorrect adjustment of the two cutting parts can lead to damage to the skin of the person or animal to be treated.

Thus, there is a need for an adjustment device that allows for consistent adjustment of the blade sets by the end user to, among other things, extremely small spacings between the cutting blades for precise hair cutting operations.

The object of the present invention is therefore to provide an adjustment device for a hair clipping device that enables a user to set the cutting sets to a maximum short distance from one another in a simple and reproducible manner, so that a maximum short cut length can be achieved safely and with the least possible effort while minimizing the risk of skin injury.

According to the invention, this object is achieved by an adjustment device for a hair-cutting device having the features of claim 1 .

Preferred refinements of the present invention result from the dependent claims.

In order to enable a better understanding of the adjustment device according to the invention for a hair clipping device, the terms and definitions used here are explained in more detail below.

The upper, movable cutting set part is referred to below as the “cutting blade” and the larger lower cutting set part is referred to as the “cutting comb” or simply “comb”. The combination of shearing blade and shearing comb with any attachments is referred to as a "cutting set". In the following the device without the cutting set is referred to as "hair clipping device".

Furthermore, the "knife-comb distance" to be adjusted with the adjusting device according to the invention is referred to as the distance from the cutting comb tooth tip to the cutting knife tooth tip. The "cut length" is the shortest distance from the tip of the shearing blade to the bevel of the shearing comb.

The knife is geometrically constrained by a so-called "linear guide" between the shearing knife and the guide piece. Thus, the knife-to-comb spacing and parallelism are unchanged in the on and off states.

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

A hair-cutting device has a device housing and a blade set that is firmly connected to the device housing. The cutting set consists of a clipping blade, which includes blade tips, and a clipping comb connected thereto, which includes comb tips. The clipping comb is detachably connected to the clipping blade and thus also to the hair clipping device by means of connecting elements such as screws.

The adjusting device according to the invention for such a hair clipping device is characterized in that it is dimensioned in such a way that it can accommodate and hold the shaving comb, so that the shaving comb can be moved relative to the device housing together with the adjusting device after loosening or partial loosening of the connecting elements that a distance between the knife tips and the comb tips can be defined.

The device according to the invention thus enables the knife tips and the comb tips to be adjusted to a maximum short distance from one another without having to dismantle and remove the entire cutting set from the device housing for the adjustment.

As a result, on the one hand, the risk of injuries that the operator can inflict when removing the shearing blade is significantly minimized. On the other hand, the distance is adjusted in a simple but nevertheless precise manner, so that a maximum short cutting length can be realized with as little work as possible. A so-called zero-overlap setting can thus be carried out very precisely using the setting device according to the invention, without this setting depending on the skill and experience of the user.

In addition, with the adjustment device according to the invention, a very quick and therefore time-saving adjustment of the knife tips and the comb tips of the cutting set can be carried out, which is particularly important when using the hair clipping devices professionally.

Preferred embodiments of the present invention are explained in more detail below with reference to the drawings. Technical features that are the same and have the same effect are provided with the same reference symbols in the figures.

To explain the effect of the adjustment device according to the invention for a hair clipper, is on Figures 1a, 1b and 2a, 2b referenced, which represent two hair cutting devices 20 with the respective blade sets 24 .

In Figure 1a a hair cutting device 20 is shown in plan view. The hair cutting device 20 has a device housing 22 and a removable blade set 24 . The cutting set 24 consists in a manner known per se of a shearing blade 26 and a shearing comb 28 underneath, corresponding to the shearing blade 26 and connected thereto, the cutting set 24 in this embodiment being a cutting set with a radial knife guide.

When the knife is guided radially, the shearing knife 28 moves in a circular arc. The knife-to-comb distance measured in Fig. 1a is shown, and the parallelism in the on and off states varies continuously with radial knife guidance. In the off state, the shearing blade 28 is always on the right or left side due to a spring force acting on it.

In the Figure 2a The hair cutting device 20 shown differs from that in 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 are always the same in the on and off state.

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

With a linear guided knife, as in Figure 2a shown, it is assumed that the shearing blade 26 and the shearing comb 28 are already parallel to one another.

With a radially guided shearing blade, as in Fig. 1a shown, there is an angular offset, depending on the position in which the knife comes to a standstill. Thus, 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 one another. The knife tips 30 and the comb tips 32, as in Fig. 1a shown covered, with a minimum distance between which can be realized.

It is therefore necessary for the adjustment devices to be adapted and suitable for the respective versions of the cutting set of different hair-cutting devices.

In 3 is a perspective view of an inventive 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 perpendicularly to the base 12 and two side walls 18 extending perpendicularly to the base 12 .

The adjusting device 10 designed in this way is dimensioned such that the dimensions of the base 12 and the walls extending upwards perpendicularly to the base 12 are suitable for a cutting set 24 of a hair clipping device 20, as in FIG Fig. 1a shown to pick up and hold on to. The shearing comb, not shown here, with the shearing blade firmly connected to it, is inserted into the box-shaped adjustment device 10 and pushed forwards in the direction of the front wall 16 until the comb tips rest against the front wall 16 .

The two side walls 18 have elongated guides 48 on their upper edge, which provide a guide surface for inserting the blade set of the hair clipping device. The elongate guides 48 are formed mirror-symmetrically, so that the parallelism when inserting the cutting set into the adjustment device 10 is ensured and it is thus ensured that the lower surface of the cutting comb 28 lies snugly against the base 12 of the adjustment device 10 .

In order to securely accommodate the shaving comb in the adjustment device 10 , a snap hook 42 is provided, which in this embodiment extends approximately centrally parallel to the front wall 16 and is only connected in one piece to the base 12 of the adjustment device 10 .

The bottom 12 of the adjustment device 10 has two recesses 14 which are dimensioned in such a way that they are provided with connecting elements, usually screws, which are provided on the lower part of the blade set for connection to the device housing of the hair clipping device.

Thus, the fasteners can be easily loosened or loosened without having to disassemble and separate the entire blade set from the device housing. Therefore, a quick and safe adjustment of the distance between the knife tips and the comb tips can be done.

In order to precisely define the distance, the front wall 16 is dimensioned in the height direction in such a way that the ridge tips extend to a lower edge of the projection 38 . The knife tips, which lie directly on the comb tips, extend up to the projection 38, so that the width of the projection 38 defines the distance between knife tips and comb tips.

Because the connecting elements are loosened in the setting device when the cutting set is in the inserted state, the two cutting elements can be set very precisely relative to one another. After the adjustment process, the screws can then be tightened again, so that the cutting set can be removed from the box-shaped adjustment device 10 again, together with the entire hair-cutting device.

The in 3 Adjusting device 10 shown has corrugated gripping surfaces 46 which are formed on the respective outer sides of side walls 18 in order to facilitate insertion of the blade set into adjusting device 10 and removal from adjusting device 10 .

In 4 is a perspective view of an inventive adjustment device 10 according to a second embodiment of the present invention. This embodiment differs from that in 3 shown in that the side walls 18 are not continuous and are not connected to the front wall 16. The side walls 18 extend perpendicularly with respect to the base 12 of the adjustment device 10 and each have a spring tongue 50 in the direction of the front wall 16, which serve to fix the shearing blade in the central position.

In addition, in this embodiment, the snap hook 42 is shorter than in FIG 3 shown embodiment, so that the recesses 14 are formed correspondingly larger, which increases the accessibility to the connecting elements of the cutting set and therefore facilitates the operability. By providing the spring tongues 50, which are used to fix the shearing blade in the central position, this adjustment device 10 can also be suitable for hair clipping devices in which the blade movement is radial.

In Figure 5a is a perspective view of an inventive adjustment device 10 according to a third embodiment of the present invention.

The adjusting device 10 according to the invention according to the third embodiment 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 floor 12 .

The front wall 16 is only connected to the bottom 12 and is designed to be elastic 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 limits it laterally, so that when you insert the cutting set together with the device housing 22 in the Adjusting device 10, the elastic front wall 16 serves 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 lie against the inner wall of the front wall 16, as is shown in Figure 5c , which is a sectional view taken along line DD of FIG Figure 5b is, is shown. Thus, a zero-overlap setting can be easily implemented.

As in the Figures 5a to 5c As shown, the front wall 16, although formed as a single piece, includes a lower elongate portion which is connected to the floor 12 and extends upwardly at a substantially right angle and an upper portion fixedly connected thereto which is shorter in dimension than the lower portion and is inclined outwards.

In order to insert the device housing 22 together with the blade set 24 into the adjustment device 10 and to hold it securely until the adjustment is made, the blade set 24 is inserted into the box-shaped adjustment device 10 from above and pressed down using a force until the edge 36 of the Shear comb 28 rests against the inner wall.

In Figure 5a Two recesses 14 are shown in the base 12 of the adjuster 10 which are sized to correspond with the fasteners of the blade set so that they can be easily loosened or loosened when the hair clipper 20 is connected to the adjuster 10.

As in the sectional view of Figure 5c As can be seen, in this embodiment the rear wall 44 is designed in such a way 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 connected therewith without play.

Thus, a simple adjustment of the edges 34 and 36 of the cutter blade 26 and the cutter comb 28 can be made without having to separate them from each other. Thus, the hair clipping device 20 can be connected to the adjustment device 10 during the adjustment process, as in this in 6 is shown.

In Figure 7a a fourth embodiment of the adjusting device 10 according to the invention is shown in perspective. The adjuster 10 is configured to have a bottom 12, as in the other embodiments described above, a side wall 18, and a rear wall 44. As shown in FIG.

As in the Figures 7a to 7c shown, a support surface 11 is provided so that the adjustment device 10 can be supported on a flat surface, with the base 12 and the side wall 18 and rear wall 44 connected thereto and formed in one piece being at an angle of approximately 50° from the flat support surface 11 extends upwardly such that when the clipper 20 is laterally inserted into the adjuster 10 along with the blade set 24, the clipper 20 extends substantially perpendicular to the support surface.

As in Figure 7a As shown, the base 12 has two recesses 14 which correspond to the fasteners of the blade set 24 so that the fasteners can be loosened or loosened when the blade set 24 is fully inserted into the adjuster.

The front wall 16 is formed such that it has a projection 38, as shown in FIGS Figures 7a and 7b shown. The crest tips extend up to a lower edge of the projection, which corresponds to the bottom 12 .

The knife tips of the shearing knife 26, which lie directly on the comb tips of the shearing comb 28, extend up to the projection 38, so that the width of the projection 38 defines the distance between knife tips and comb tips, as in FIG Figure 7b shown.

As in Figure 7a shown, the side wall 18 is formed in such a way that it has a projection 19 in the direction of the front wall 16 . The projection 19 extends further in the direction of the open end of the adjustment device 10, via which the blade set is guided into the adjustment device 10. Thus, the shear comb 28 can be pushed completely into the adjustment device 10 up to the inner surface of the side wall 18 .

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

In the Figures 8a to 8d a fifth embodiment of the adjusting device 10 according to the invention is shown. The adjustment device 10 has a base 12 in which two continuous recesses 14 are formed, so that the connecting elements of the cutting set can be loosened or detached through these recesses 14 .

Furthermore, the adjusting device has two side walls 18 which extend parallel to one another and are connected to the base 12 ′ and to a front wall 16 . The side walls have inside lateral guides 48 for the parallel alignment of the shearing comb 28 and the shearing blade 26 in the Figures 8c and 8d are shown. The lateral guides 48 are designed as spring tongues 50 so that they also serve as a holder for the shearing comb 28 and the shearing blade 26 .

The bottom 12 has, as in the Figures 8a, 8c and 8d shown, at one end opposite the front wall 16 has a snap hook 42 which, as in FIG Figure 8c shown, is designed to receive and hold the shear comb 28 during adjustment. The snap hook is formed centrally on the base 12 ′, between the two recesses 14 .

As in the Figures 8a, 8d shown, the lateral guides 48 are arranged such that the spring tongues 50 only the razor, as from Figure 8d As can be seen, hold it in the central position so that the shearing blade 26 is adjusted laterally relative to the shearing comb 28 . This embodiment is therefore suitable for a hair clipper 20 with a radial or linear knife guide.

In Figure 9a is a perspective view of an inventive adjustment device according to a sixth embodiment of the present invention is shown.

In contrast to the adjustment devices described above, the in Figure 9a The adjusting device 10 shown has a base 12', which is designed like a bar and is dimensioned in such a way that it can be inserted into a recess 17 provided between the shearing comb 28 and the shearing blade 26 in the installed state, as is shown in Fig. 9e is shown. The shearing blade 26 is positioned in relation to the shearing comb 28 via the recess 17.

The web-like base 12' extends essentially perpendicular to a side wall 18' of the adjustment device 10 and runs parallel to a rear wall 44', which is shorter than the base 12'.

The adjusting device 10 has on its side wall 18' an outwardly extending handle 15 which serves to insert the device into the recess 17, as in FIGS Figures 9a, 9b and 9d is shown.

In Figure 10a is a perspective view of an inventive adjustment device 10 according to a seventh embodiment of the present invention. The adjustment device 10 has a front wall 16 which is connected to two laterally arranged side walls 18 .

The side walls 18 are fixedly connected to two mutually parallel bottoms 12, 12' of the adjustment device 10, as in FIGS Figures 10a, 10c and 10f is shown. The two floors 12, 12 'are formed inclined relative to the front wall 16, so that when inserting the hair clipper 20 together with the cutting set in the adjustment device 10, the hair clipper 20 relative to the adjustment device 10 is substantially perpendicular, as in Figs Figures 10d and 10g shown, is arranged.

In Figure 10c the shearing comb 28 is inserted together with the shearing blade 26 into the first opening of the adjustment device 10, so that the shearing comb 28 touches the floor 12 along to the adjoining front wall 16, as in Figure 10b 1 and adjustment of the spacing between the tips of the shear comb 28 and the shear blade 26 is made after loosening the fasteners.

It is to be noted that in Figure 10b only the openings in the shear comb 28 provided for the fastening elements are shown. The first opening in the adjustment device 10 is suitable for adjusting the distance between the tips of the clipping comb 28 and the clipping blade 26 of a hair clipper with a radial blade guide.

In Fig. 10f , which is a sectional view along the line BB of Figure 10e 1, the blade assembly is inserted into the second opening of the adjuster with the underside of the trimmer comb 28 resting against the floor 12' and adjustment of the distance between the tips of the trimmer comb 28 and the trimmer blade 26 of a hair clipper with a linear blade guide is suitable.

the Figures 11a-11f 12 show the adjustment device 10 according to another embodiment of the present invention.

As in Figure 11a As shown, the adjuster 10 is constructed to have a base 12 connected to a front wall 16 as in the other embodiments, however, the base 12 is connected to the front wall 16 substantially in the middle thereof. At the rear end of the base 12 it spreads into two parts, upwards and downwards, so that the parts each have a rear wall 44 . The base 12 is connected laterally to two side walls 18 which extend approximately in the middle upwards and downwards from the base 12 and serve as a lateral boundary for the cutting set and as gripping surfaces for the adjustment device 10 .

The in the Figures 11b and 11c The adjustment device 10 shown is suitable for adjusting a hair clipper with a radial blade guide. In Figure 11b the adjustment device 10 is shown from the front. The edge 34 of the shearing blade 26 is in the middle position, as in Figure 11b shown.

In 11c FIG. 12 is a sectional view taken along line FF of FIG Figure 11b 1, from which it can be seen how the shearing blade 26 is adjusted in relation to the shearing comb 28. In the Figures 11c and 11d shows the double use of the adjustment device 10, namely for a hair clipping device with a radial knife guide, as in FIG 11c shown, and for a linear blade guide hair clipper such as this Figure 11d shown example. The two uses of the adjustment device differ in the design of the respective projection formed on the front side 16 or 16 ′, which is suitable for adjusting the shearing blade 26 relative to the shearing comb 28 .

This embodiment has the advantage that the adjustment device can be used twice, namely once for the adjustment of hair clipping devices with a radial knife guide, as in FIGS Figures 11b and 11c shown, and also for the adjustment of hair clippers with a linear blade guide, as in Figs Figures 11a, 11d, 11e and 11f shown. It should be noted that the device according to Figures 11b and 11c the lower of the in Figure 11a shown adjuster represents.

In the Figures 12a-12h 1 is shown an adjustment device according to a ninth embodiment of the present invention. The adjustment device 10 is constructed in two parts and has a first part 52, as shown in FIGS Figures 12b and 12c shown, and a second part 54 as shown in FIGS Figures 12d and 12e shown, on. The first part 52 is sized to be inserted into the second part 54 and held in place by a snap fit.

As in Figure 12b As shown, the first part 52 is similar to the one-piece embodiment according to FIG 4 constructed and has a bottom 12 which is connected to two opposite side walls 18 arranged parallel to one another.

At the front part of the floor 12 there is a front wall 16 which extends upwards substantially perpendicularly to the floor 12 and has a projection 38 which in this embodiment is formed at the upper part of the front wall 16 with interruptions.

The projection 38 serves as a stop surface for the corresponding tips of the shearing blade 26 in the inserted state, as in FIG Fig. 12h shown. The projection 38 is spaced from the floor 12 and provides a stop surface for the tips of the shearing comb 26, as in FIG Fig. 12h shown

The base 12 of the first part 52 of the adjustment device 10 has a recess 68 approximately in the middle, which in this exemplary embodiment defines a stop 70 lying opposite the front wall for the latching of the second part 54 . The second part 54, as in Figure 12d shown, a corresponding detent 78 to allow a snap connection between the two parts 52 and 54, as in 12f is shown.

In 12a Both parts 52 and 54 are shown inserted into one another. 12f shows the two parts 52 and 54 of the adjustment device 10 in the latched state, with the latching lug 78 of the second part 54 forming the latching connection with the stop 70 of the first part 52.

As in Figure 12d shown, the second, lower part 54 has an elevation 72 opposite the latching lug 78, which serves as a lock so that both parts 52 and 54 of the adjustment device 10, which are guided one inside the other, cannot move relative to one another as long as the cutting set has not yet been inserted into the Adjusting device 10 is introduced.

The first, inner part 52 of the adjustment device 10 forms a receptacle for the cutting set, with the shearing comb resting on the inner surface of the inner part 52 and being held prestressed by it. The second, outer part 54 of the adjustment device 10 is used to hold the preload.

The first part 52 and the second part 54 are there, as in FIGS Figures 12a and 12f shown slidable relative to each other to urge the shear blade to a center position. The spring tongues 50 of the first part 52, as in Figure 12b shown, are used after the parts 52 and 54 have been pushed together into one another to fix the shearing blade in a central position.

The side walls 18 of the first part 52 each have, on their outer sides adjoining the second part 54, a web 58 extending in the longitudinal direction for the axial guidance of the second part 54, as shown in FIG 13c shown.

The second part 54 is designed in such a way that on the corresponding walls 76 it has an elongated recess 64, which is designed in the form of a groove, for receiving the respective adjoining web 58, as is shown in 13c is shown.

As in the Figures 13d and 13e shown, in the second part 54 of the adjustment device there is a recess 66 formed in the respective base 12 for receiving a tool 60, the tool 60 being grippable and removable when the adjustment device is in a completely closed position or else in an open position in order to to at least partially loosen the connecting elements 62 of the shearing comb 28, as in 13c is shown.

In this way, the connection between the shaving comb and the shaving cutter is released in a simple manner and an adjustment is made without completely detaching the two parts from the hair-cutting device.
