Description

 Tool handle and hand-held tool with such

 tool handle

The present invention relates generally to hand tools and related items

Components, wherein a surface to be machined, such as areas of the skin of a person to be machined.

In many sectors of industry and households, there is a renewed tendency to use mechanical tools, as these often offer advantages in terms of independence of energy sources, cost, weight and size. In particular, for activities that are often, such as several times a week or daily to perform, but require only a short period of time, preferably hand-held tools and their components can be used efficiently. An example is the treatment of areas of the body surface of a person, such as for shaving, massaging, applying substances, and

the like when the use of a skin surface acting on

Tool is required or at least the use of a tool facilitates the process. Such mechanical hand-held tools, such as

Razors, and the like not only offer advantages in terms of cost and

Energy expenditure compared to corresponding electric tools, but also often differ in the result of the application carried out, since the process to be used in the treatment is usually better controllable by hand compared to electrical tools. For example, in the opinion of many, hand shaving using a razor blade provides a blade block

Users much better results than an electric shave, in particular, the application and the control of the shaving process is classified by many users of hand-held tools as significantly beneficial. Hand-held shaving tools are known in the art, for example, in which one or more blades are mounted on a support which in turn has a receptacle adapted to insert a single finger, usually the index finger, and to hold the shaving tool serves. With the help of the thumb and / or another finger then the guiding and

CONFIRMATION COPY Move the hand-held shaving tool over the appropriate area of the skin to perform the shaving. This results in comparison to

electric razors a higher degree of flexibility and controllability of the entire process, since in particular correspondingly suitable blades or

Blade blocks are applicable, which may otherwise be for electrical

Razors would be unsuitable. In particular, document WO 2003/051585 A1 describes a hand-held razor device with two razor blades arranged on different sides, in which in the manner described above by tilting the device either one side with a razor blade with the skin surface to be treated or the other side with razor blade the skin surface can be brought into contact. That is, when reversing the

Shaving direction, the body of the device that receives the individual finger of the user, tilted so that the other razor blade can be used.

However, when "handing" sensitive surfaces through a hand-held tool, it is necessary to be able to exercise precise control over the tool to achieve the desired result, for example, the result and well-being of a shaving operation are substantially dependent upon the handling of the mechanical hand-held razor from.

It is therefore an object of the present invention to provide means by which the use of a hand-held tool, such as a tool for

Treatment of skin areas of a person, can be performed efficiently and yet sensitive.

According to one aspect of the present invention, this object is achieved by a tool handle. The tool handle according to the invention comprises a handle portion having a first finger receiving portion and a second finger receiving portion, each adapted to enclose more than half of the circumference of a respective inserted finger. The tool handle further comprises a holding part connected to the grip part, which is formed, one or more

To hold tool components. The tool handle according to the invention, which serves to receive and hold corresponding suitable tool components, has at least two finger receiving parts which enclose corresponding fingers sufficiently far enough to allow "sticking" of the tool grip to the two inserted fingers the respective finger is enclosed by more than half.

It should be noted that the description of the structure of the finger receiving parts based on the circumference of a finger is to be understood that a suitable size, such as a distance between two on a line and opposite points of the respective finger receiving parts has a measure that the anatomical conditions of Persons or appropriate groups of persons. Tool handles can be provided for different groups of people, which are then adapted to the anatomical conditions relevant to the specific group of persons.

Due to the provision of two such finger receiving parts, the tool handle can be on the one hand "fasten" efficiently on the user's hand, so that unwanted movements of the tool during use in the

Substantially avoided, and on the other hand, the movements of the tool handle and thus attachable thereto tool components can be well controlled, while a desired contact force can be generated simultaneously. For example, it is possible with the tool handle according to the invention in a well-controlled manner, a desired contact force or pressure when massaging, shaving, generally in the skin treatment to apply, without that the

Danger of the occurrence of an undesirable angle, direction, et cetera of one or more tool components is increased, as is the case, for example, with hand-held shaving, the only a single

Own finger recording. In particular, in sensitive applications that require about a treatment of skin areas of the user or a third person, so are the required contact force and controllability of the

Movement direction given in an efficient manner, with the available

Usage width or usable area of one or more

Tool components are essentially fully utilized at any time can.

In a further embodiment, the grip part has a contact area for one or more further fingers. With this design form, the aforementioned advantage of a well-controlled metered contact force, if required, can be further improved in conjunction with good controllability, since at least one further finger of the user person can be placed on the support area and thus also to control the bearing force and direction of the

Tool component is available.

In one embodiment, the support area is formed so that less than half of the circumference of a finger is enclosed. Thus, the support area has no function for the adhesion of the tool handle on the hand of

User person, but can still control the movement and the

Support force to be used with, in addition, a high degree of finger freedom is guaranteed.

In a further embodiment, the grip part has at least one further finger receiving part, which encloses more than half of the circumference of an inserted finger. In this embodiment, at least three fingers of the user person can be inserted into the respective finger receiving parts as needed, so that a good grip of the tool grip on the hand of the

User results. In addition, here are also the advantages mentioned above with regard to the controllability of the bearing force and the

Movement direction of the tool handle reached.

In an advantageous embodiment, the first finger receiving part and the second finger receiving part are arranged adjacent to each other. In this

Embodiment are therefore preferably two adjacent fingers of the user's hand to introduce into the respective finger receiving part, which is due to anatomical reasons, a relatively high contact force using

can reach neighboring finger.

In a further embodiment of the present invention, the first Finger receiving part and the second finger receiving part separated by a support area. In this embodiment, the design is such that at least one user's finger is positionable between the first finger receiving part and the second finger receiving part, so that there is a relatively large lever arm for guiding the tool handle, even if one or more fingers are temporarily lifted off the support area , The support area thus provides an increased degree of finger freedom for the finger or fingers positioned therein, as previously described, without, however, compromising the controllability of the tool handle.

In a further embodiment, the first and / or the second form

Fingeraufnahmeteil a closed configuration such that the circumference of a corresponding inserted finger is completely enclosed. The finger receiving parts provided with this closed configuration ensure that the tool handle reliably adheres to the hand, that is, to the two fingers inserted into the first and second finger receiving parts, irrespective of whether the tool handle is being used, such as for machining Treatment of a surface, or just a short break in treatment is present. In other embodiments, the configuration of the first and / or the second finger receiving part is not closed, it being understood that a distance of 1 mm or less up to 10 mm between corresponding

End regions of the respective finger receiving parts can be provided. This further allows a reliable attachment to the corresponding

on the other hand, however, gives a higher degree of tolerance with regard to different circumferences of the user's fingers for a given size of the opening of the finger receiving part. For example, the first and / or the second finger receiving part may be made of an elastically deformable material or may have integrated another type of spring action, so that even with large dimensions of the respective finger to be introduced a corresponding expansion of the first and / or second

Finger receiving part allows the recording of the finger. In this

Embodiment, ie not completely closed configuration and use of a resilient material or a spring mechanism can the overall dimensions may be selected to be smaller overall, since adaptation to the anatomical conditions of a user with larger fingers is still possible. Furthermore, by the elastic action of the first and / or the second finger receiving part, if they have a non-closed configuration, a very reliable fit of the tool handle to the finger or the hand of the user can be achieved.

In another embodiment, three or more finger receiving parts are provided, each having a closed configuration or each having a non-closed configuration. Also, a mixed configuration is provided in embodiments wherein one or more finger receiving parts have a closed configuration and the remaining finger receiving part (s) have a non-closed configuration. For example, in one

Embodiment all finger receiving part, about two, three or four

Finger receiving parts, a closed configuration, wherein the respective

Inner diameters are equal, or may be different, in order to achieve approximately an adaptation to the anatomical conditions.

In other embodiments, two or more of the finger receiving members have a non-closed configuration, as previously discussed, and in some preferred embodiments have some resilience of the finger receiving members

is provided, for example by the elastic deformability of the material from which they are formed, or by the provision of a corresponding

Spring mechanism, so that the aforementioned properties of greater flexibility to the adaptation of anatomical conditions in conjunction with optionally smaller overall inner diameters and better adhesion to the user's hand are achieved.

In a further preferred embodiment, the handle part has two

Finger receiving parts for receiving each index finger and a user's small finger and a support area for receiving middle and ring finger of a user, wherein the support area between the two finger receiving parts are arranged. Advantageously, the support area has two wells separated by a web. The tool handle can then safely through the outer fingers held by one hand of the user and all four fingers (except the thumb) of the user's hand exert a very precisely adjustable pressure while at the same time secure and comfortable holding the tool handle. Preferably, the tool components are approximately directly below the finger receiving parts or below the finger receiving parts, but to the inside offset, for example

preferably between the finger receiving parts and the support area arranged. As a result, a very good application of the tool components is possible because a secure holding and a sensitive pressure exercise is possible.

Advantageously, a support or spring element is provided which acts resiliently on contact with a surface to be machined. The support element can advantageously be used to control the movement of the tool handle, in particular on a surface to be processed, since there is a higher degree of control with respect to the distance to the surface to be processed, if a corresponding counterforce can be felt by the user. For example, the support element may be mounted so that at

standard contact with a surface to be processed almost no contact of the support element with the surface takes place while an unwanted excessive contact force or too small selected distance by the user leads to a contact of support element and surface, which is thus clearly felt, but initially no negative Impact on the work to be done

Surface exercises. This can for example be extremely advantageous if

Skin areas of the user or a third person to "edit" are, such as shaving, but also during massaging, applying and distributing liquids, and the like.

The support element is also particularly advantageous due to its resilient

Effect of suitably holding the tool components in place, such as when using a razor blade or a blade block. The support member may therefore provide elastic repositioning upon contact with the component which carries about a razor blade.

In an advantageous embodiment, the holding part is at least for holding a or a plurality of blades or one or more blade blocks. In this embodiment, the tool handle according to the invention is particularly suitable for use in shaving, since the holding part a corresponding

Has configuration for receiving matching blades or blade blocks.

In particular, in the context of a shave a suitable contact force in conjunction with good control of the movement of the tool handle for a desired success of the shaving process is advantageous and can be achieved efficiently in particular due to the aforementioned properties of the tool handle according to the invention. For example, surface areas that occur during the

Application, are not well visible, such as the shaving of the scalp, and the like, the aforementioned properties are advantageously exploited to the required balance between bearing force, controlling the

Movement direction, utilization of the entire available cutting surface, etc. to realize.

According to a further aspect of the present invention, the aforementioned object is achieved by a hand-held tool having a tool handle as described above and as further explained in the detailed description below. The cited tool further includes one or more tool components attached to the support member. Due to the special design of the tool handle, as before and as in the rest

is described, the hand-held tool according to the invention can be used particularly efficiently and controlled, especially in the processing or treatment of surfaces. The holding part is advantageously designed so that desired tool components, such as razor blades, blade blocks, massage attachments, etc. can be used. In other embodiments, the one or more tool components are already permanently installed when substantially only a limited shelf life of the tool components without possibility of replacement or use over a relative

intended for a limited period of time.

In advantageous embodiments, two or more tool components, such as razor blades, blade blocks, and the like, may be attached to the support member simultaneously so that a particularly efficient application can be achieved. In one embodiment, for example, at least two razor blades or blade blocks are arranged opposite one another, which enable a shaving action in at least two mutually opposite directions. In a further advantageous embodiment, a first

 Tool component at least a first razor blade and a second tool component has at least a second razor blade, wherein the two tool components are arranged so that the at least one first razor blade and the at least one second razor blade at

intended use simultaneously with one to be treated

Body surface are in contact.

That is, by this inventive arrangement of the two tool components and thus the two razor blades or blade blocks when used as a shaver contact with the body surface to be treated for both

Components are given at the same time, whereby a stable contact of the two tool components is ensured. The term "intended

Use is to be understood that the tool when used as a razor, at least for large body surfaces, such as the scalp, with both tool components simultaneously rests on the body surface and is moved there in the desired direction, both tool components with the body surface to be treated in This ensures reliable positioning and always ensures that a suitable angle between the razor blade and the skin surface is maintained As explained above, reliable application of force is also well controllable due to the grip portion Ensures a tilting of the

Shaving tool, for example, when reversing the direction of shaving is therefore not required in contrast to the prior art described above. This allows a more accurate execution of the shave, without constantly watching the movement of his own hand, which is particularly advantageous in

Use as a head razor.

In a further advantageous embodiment, the hand-held tool in the form of a shaver comprises a first tool components with at least one a first razor blade and a second tool component having at least one second razor blade, the at least one first razor blade and the at least one second razor blade facing each other. At this

Embodiment of the present invention, the tool handle may have any training and is not limited to its described in the present application and / or illustrated training. This type of arrangement ensures that when reciprocated the hand-held

While the other razor blade does not contribute to the cutting, but provides a stable position and movement of the tool, as stated previously. The at least one first and the at least one second razor blade are preferably spaced about a hand's breadth. This is particularly advantageous, in particular when the handle part has two finger receiving parts for receiving each index finger and small finger of a user and a support area for receiving middle and ring finger of a user, wherein the support area between the two

 Finger receiving parts are arranged. The "fixedly mounted" index fingers and small fingers of the user can apply pressure to the razor blades in a particularly sensitive and stable manner In another illustrative embodiment, a distance between the first and the second tool components, if these each have at least one razor blade, along a longitudinal direction the gripping part is larger than a dimension of a finger receiving part along the longitudinal direction and / or a dimension of a rest area along the longitudinal direction.

In such an embodiment is thus a pronounced distance in

 In the longitudinal direction and thus in the proper use of the tool as a shaver, ensured in the direction of shaving, so that the benefits of reliable positioning and movement of the tool are given. In particularly advantageous embodiments, the distance is so great that it is more than two

Fingerbreit or larger, so the distance has a dimension that is greater than the sum of the dimensions of two finger receiving parts, so that so that

significant proportion of the extension of the tool in its longitudinal direction

is used to ensure stable positioning and movement of the tool as a shaver. In a further aspect of the present invention, the above-mentioned object is achieved by a hand-held razor with a tool handle as already described or as it is also shown below in the detailed description. The hand-held razor further includes a first

 A razor tool component having at least a first razor blade and a second razor tool component having at least one second razor blade. The hand-held razor is characterized by the fact that the first

Shaving tool component and the second shaving tool component are arranged so that both shaving tool components in

intended use simultaneously with one to be treated

Body surface are in contact.

In the same way, a reliable positioning on the body surface to be treated is possible due to this arrangement since both shaving tool components always serve as support elements.

In accordance with another aspect of the present invention, there is provided a handheld razor having a tool handle as previously described or described below. Furthermore, a first

 A razor tool component having at least a first razor blade and a second razor tool component having at least one second razor blade provided, wherein the first razor tool component and the second

Shaving tool component are arranged so that the at least one first razor blade of the at least one second razor blade faces.

 Thus, as already explained above, a comfortable shaving can be ensured since, when moving substantially along the longitudinal direction of the grip part, a shaving function, directed towards the center of the grip part, of a respective razor blade is obtained.

Further, combinations of the two last-mentioned aspects of the present invention are also possible such that both the simultaneous positioning of the razor blade-carrying components on a subject to be treated

Body surface and the facing arrangement of the razor blades is realized. In these cases, a suitable large distance between the two razor blades or components can be selected so that a very intrinsically stable razor, for example as a head razor, is obtained. Further advantageous embodiments of the present invention will become apparent from the following detailed description and from the dependent claims. In the drawings, the same or similar reference numerals designate the same or corresponding elements. All described and / or illustrated features alone or in any meaningful combination form the subject of the present invention, regardless of their

Embodiment of the present invention shows.

With reference to the drawings, further embodiments of the present invention will be described in more detail below. FIG. 1 shows a perspective view of a tool handle 100 according to an embodiment of the present invention. The tool handle 100 includes a handle portion 101 having a first finger receiving portion 110 and a second

Finger receiving part 120, which are designed so that they can receive a corresponding finger of a user person and thereby enclose more than half of the circumference of the corresponding finger. As explained in more detail below, while the dimensions, such as a diameter, the

Finger receiving parts 1 10, 120 so that they are anatomical

Given the circumstances of a typical user. In the

1, the first finger receiving part 110 and the second finger receiving part 120 have a closed configuration, i. when a finger is inserted into the corresponding finger receiving part, it is completely enclosed in its circumference. The first and the second finger receiving part 110, 120 are thus designed such that upon insertion of a corresponding finger due to the encircling of a large part of the circumference of the respective finger unfold a certain adhesion to the respective finger, so that the tool handle 100 also adheres, if no active intervention by the user to hold the handle 100 has taken place.

As previously explained, in non-closed configurations, i. if a gap between mutually facing ends of the finger receiving parts 1 10, 120, which are not shown in the figure, a distance from one another of 1 mm to several millimeters, about 10 millimeters, nevertheless sufficient adhesion is ensured. In other embodiments, in which a non-closed configuration is used, the finger receiving portions 110, 120, or at least one of them, have a resilient or resilient behavior, so that a corresponding expansion and thus adaptation to the dimensions of an inserted finger takes place. When using an elastically deformable material or providing a suitable spring mechanism, a corresponding expansion can lead to increased adhesion of the tool handle 100 to the hand of the user, so that a reliable handling is ensured.

In the illustrated embodiment, the finger receiving parts 1 10, 120 suitable bearing surface 111, 121, which ensure a comfortable resting of inserted fingers and thus form a large contact surface for controlling the movement of the handle over a surface. In the opposite direction, the finger receiving parts 110, 120 may have a significantly reduced contact surface (not shown), since upon contact of the finger on this surface only the adhesion of the tool 100 is to ensure finger on, but no force on a surface to be machined exercise, as for example by the

Support surface 111, 121 can be done efficiently. The grip part 101 of the tool handle 100 in this embodiment further comprises at least one support area, wherein in the illustrated embodiment, a support area 150 and a support area 160 are provided. The

Bearing areas 150, 160 are designed so that they encompass the circumference of a resting finger with only half or less than half, so that a high degree of finger freedom is ensured, yet by appropriately suitable bearing surface 151, 161 a suitable bearing force and control of the tool handle 100 are ensured when used for surface treatment. In the intended use, advantageously e.g. four fingers of the right hand of a user in the finger receiving parts 110, 120 and on the support areas 150, 160 arranged. More specifically, for example, the index finger in the finger receiving portion 110, the middle finger on the support portion 150, the ring finger on the support portion 160 and the small finger in the

Finger receiving part 120 arranged. The tool handle 100 further includes a support member 170 that is configured to mount a suitable tool component, such as a razor blade, a blade block, a massage unit, a fluid dispenser or dispenser, and the like. In the illustrated embodiment, the retaining member 170 is configured to receive and retain at least two tool components, which may be of the same or different types.

Further, one or more spring elements 190 are provided, which in the

illustrated embodiment, in each case on a corresponding finger receiving part 120, 110 (hardly visible there) are mounted. The spring elements 190 serve this purpose the (not shown) tool component, such as a razor blade block, which is for example rotatably mounted, due to a basic position. As the tool handle 100 moves, the razor blade block becomes

rotated according to the surface contour or the shaving movement, and for example when removing the razor blade block from the skin surface, this is spring-back to the starting position. Further, on the rib 155, which is provided below the tool handle 100, stops 191st

formed which a rotation or tilting of the (not shown)

Tool component, such as a razor blade block, limit to a predetermined angular range.

FIG. 2 shows a first (transverse) side view of the tool handle 100, wherein the second finger receiving part 120, the spring element 190 attached thereto and the corresponding component of the holding part 170 are shown. Like from this one

It should be noted that information on the location and orientation of the

 Tool handles 100 or components thereof, such as "top," "bottom," "side," and the like, and terms derived therefrom are not to be understood as absolute terms, but rather are to be considered in relation to a surface to be machined (not shown) to which, when applied by one or more tool components mounted on the support member 170, at least some, albeit slight, force is applied to the surface, which is "under" the support member 170 in the illustration of Figure 2, but not shown.

Typical dimensions for the width 122 may be in the range of 5-20 mm, while the width 123 may be in the range of 3-10 mm in some embodiments.

FIG. 3 shows the tool handle 100 in a further (longitudinal) side view, in which the finger receiving parts 110, 120 in conjunction with the support area 150, 160 are shown, so that a length L for the tool handle 100 results Essentially given by the dimensions of these parts and areas. Furthermore, the holding part 170 is shown, which is for receiving and holding two

Tool components is formed, in other embodiments, the design of the holding part 170 is such that only a single

Tool component, such as a razor blade or a single blade block, or more than two tool components are received and held. Furthermore, the spring elements 190 are shown on the outside of the respective

Finger receiving parts 110, 120 are mounted and are made for example of the same material as the finger receiving parts. The length L may be in the range of typically about 7 cm to 14 cm, depending on the anatomical conditions of a group of users, for whom the

Tool handle 100 is designed, and also depends on the wall thickness of the respective finger receiving parts and support areas. The dimensions of the

Tool handle 100 can be specially adapted to certain groups of

Users, such as adult women, who usually have smaller hands, groups of men, each with different sizes of their hands, etc. vote. In the illustrated embodiment, the diameters 115, 125 of the respective finger receiving parts 110, 120 are correspondingly for the

Recorded by finger of the respective target group and can be in the range of 10 mm to 30 mm or more. Furthermore, the finger receiving parts 110, 120 may have different diameters, so that in the illustrated embodiment, for example, the anatomical differences between

Forefinger and little finger is taken into account. Similarly, the bearing areas 150, 160 may be designed to be anatomical

Conditions of the desired target group of users correspond.

Depending on the cross-sectional shape of the respective finger receiving parts and bearing areas, corresponding circumferential dimensions 116, 126, 156, 166 result, so that the parts with the finger receiving parts 1 0, 120 a large part of the circumference of a finger

is enclosed, while in the receiving areas 150, 160 a large part of the circumference of the corresponding finger is not enclosed. The cross-sectional shape may in other embodiments of the circular shape shown in Figure 3

differ. In the case of deviation from the circular shape, correspondingly larger dimensions result for the respective circumference. 4 shows a top view of the tool handle 100 from the direction of the holding part 170, wherein in this embodiment, the corresponding bearing surfaces 111, 121 of the finger receiving parts 110, 120 are selected to be larger than the bearing surfaces 151, 161 of the bearing areas 150, 160. In other embodiments (not shown ) can be provided the same size bearing surfaces, or the bearing surfaces can differ between the finger receiving parts, with any combinations of sizes of the respective bearing surfaces is possible. Figure 5 shows a top plan view of the tool handle 100 for the embodiment shown in Figure 4 in which the bearing surfaces 151, 161 are equal to each other but smaller than the two bearing surfaces 111, 121, which are mutually equal can be explained in others

The tool components 710, 720 may be movably held on the holder 670, for example, rotatable at least about an axis, wherein a rotation about a defined angular range about an axis which is approximately perpendicular to the length L may be advantageous. The holder 670 with the further component 671 in conjunction with the tool components 710, 720 is designed in some embodiments so that the components 710, 720 can be removed if necessary, such as when replacing the components or during processing, such as cleaning, etc. of the components 710, 720. In other embodiments, the components 710, 720 are permanently connected to the bracket 670, if appropriate for the application being considered. In an advantageous embodiment, the tool components 710, 720 are provided in the form of a razor blade or a blade block, so that the hand-held tool 700 is best suited as a hand shaver, for example for shaving the scalp, facial skin, legs, etc. such

Razor blades or blade blocks are available in large numbers in a variety of design forms in the prior art, so that for already available components 710, 720, the holding part 670 is suitably adapted to receive them. In other embodiments, components 710, 720 may be configured for other applications, such as massage, and the like. In other embodiments, not shown, is only a single

Tool component or there are more than two tool components on the holding part 670, which is designed to be suitable attached. Also in this case, the holder 670 and the one or more tool components may be configured to provide a permanent coupling or a mechanically releasable connection. In one embodiment, the tool 700 represents a hand-held razor in which the tool components 710 and 720 are respective razor tool components, each having at least one razor blade (not shown). That is, component 710 may include, for example, 1, 2, 3, or more razor blades arranged in close proximity with each other and having substantially the same orientation so that upon contact with a body surface to be treated, a single corresponding shaving direction predetermined by the body surface is obtained. A collection of two or more razor blades is also referred to herein as a blade block. Similarly, the tooling component 720 may have two or more corresponding parallel-oriented razor blades, if deemed desirable for achieving a desired shaving effect.

As can be seen from FIG. 7, the two razor tool components 710, 720 are arranged such that when the shaving tool 700 is seated on a body surface to be treated when used properly, both tool components 710, 720 are in contact with this surface simultaneously , This results in a stable resting of the tool or razor 700 on the body surface to be treated, wherein due to the formation of the handle portion 600 according to the properties already described achieves a high degree of controllability of both the bearing force and the movement over the body surface to be treated become. In the illustrated

Embodiment is the distance between the two components 710 and 720 in the longitudinal direction L chosen so that this dimension is at least greater than the corresponding dimension in the longitudinal direction L of a finger receiving part. that is, The distance between the two components 710 and 720 is greater than a diameter of one of the finger receiving parts, in particular, the distance is greater than the diameter of two finger receiving parts. That is, in the illustrated

Embodiment, at least at least two fingers of the user are present between the two components 710 and 720, so that due to the relatively large distance a high degree of stability of the razor 700 in the intended use, i. when lying on and moving on and over the body surface to be treated is ensured. In advantageous embodiments, the at least one razor blade (not shown) of the component 710 and the at least one razor blade (not shown) of the component 720 face each other, i. in the longitudinal direction L, a shaving direction of the component 710 is opposite to a shaving direction of the component 720, with the respective shaving direction of the components 710, 720 facing the center of the shaver 700. That is, in Figure 7, a shaving effect occurs

 Movement on a body surface (not shown) to be treated along the longitudinal direction L by the razor blade of the component 710 as it moves to the lower right and the razor blade of the component 720 has a

Shaving effect when the component 720 shifts to the upper left (each parallel to the longitudinal direction L). The shaving direction or cutting direction is thus directed inward for both components 710, 720, i. in the direction of a center point of the razor 700 with respect to the longitudinal direction L. This results in each case when moving substantially parallel to the longitudinal direction L.

Shaving effect by one of the components, while the other component continues to provide the stable support on the body surface to be treated and thus stability during movement. By reciprocating substantially along the longitudinal direction L thus results in an efficient

Shaving effect, without generally the position of the handle portion 600 must be changed with respect to the resting fingers. Thus, no repeated tilting of the razor 700 is required during the movements. Rather, a uniform movement with almost constant position of the hand and the Rasierwerkzeugkomponenten 710, 720 are performed, yet the reversal of the direction of shaving takes place at the respective movement end points. Of course, it should be noted that the absolute orientation of the shaver 700 through the contour of the body surface to be treated is determined.

The invention has been explained in more detail above with reference to preferred embodiments thereof. However, it will be apparent to those skilled in the art that various modifications and changes can be made without departing from the spirit of the invention.
