Abstract

PURPOSE: To decrease the degree of fatigue in use by easily holding an apparatus by forming a housing with at least one recess suitable for accepting a finger in order to determine the position of a hand to a drive element. CONSTITUTION: This apparatus has a shaving head 2 provided with three shaving units 3 and a housing 1 provided with provided with a housing part 4. In the housing 1, a recess 9 for the finger such as the thumb of a hand for holding a shaver is formed at the practically same height as a drive element 8 on its front surface. Therefore, the apparatus can be extremely conveniently held and one or more fingers are automatically placed proximately to the drive element. Especially, when sliding the drive element 8 in the directions of P1 and P2 , through the finger in the slender recess 9 extended respectively vertically to the direction P2 and P1 , the required stress can be easily transmitted to the housing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shaving device having a housing in which at least one shaving unit is provided, the housing also forming a grip part and comprising a manually actuated drive element. It has walls.

Such a shaving device is, for example, USP 3.99
Known by 7,967. The device shown here has a drive element for the motor switch and a drive element for the trimmer.

The purpose of the invention is to make such a device easier to operate, and to this end the features of the invention include a device suitable for receiving a finger in order to position the hand relative to the drive element. At least one recess is formed in the housing.

During use, the shaving device is most often held in one hand. The free other hand is therefore used, for example, to pull the surface of the skin that is about to be applied. When the user places a finger, for example, y, in the recess, the user's finger will automatically be placed very close to the drive element, so the user can send a message to the device without changing the σI.
You can operate the drive element here.

Since one finger is placed 1α in the recess, the device becomes easier to use and the degree of fatigue from using this device is reduced.

The force that forces the device against the skin is applied to the device by the hand. By providing the device with a recess forming a finger rest, it is no longer necessary to hold the device so firmly, since this force is no longer solely a frictional force generated by holding the housing correctly tIF.

In addition, especially when this driving element is of a sliding type, the recess in the housing allows the reaction force to be easily transmitted to the housing by a finger placed in the recess.
Operation of the drive element becomes more convenient.

The presence of the recesses also reduces the cross-sectional dimensions of the shaver where it is held by the bristles, thereby reducing fatigue from use in this position.

Particular embodiments of the invention are described in the dependent claims.

Some embodiments of the present invention will be described with reference to the accompanying drawings.
This will be explained in detail based on an example.

The shaving device shown in FIGS.
The shaving head 2 has a housing l with a housing part 4 and a shaving head 2 with shaving units 3 . A known type of shaving unit 3 (not described in detail) consists of two co-operating shaving members, one of which is rotatable. This shaving device is inclined with respect to the hair direction of the housing part 4. The axis 5 of the housing part 4 and the axis 6 of the shaving head 2 thus form an obtuse angle α with respect to each other.

On its rear side, the housing has a trimmer 7 with a drive element 8 slidable in the directions indicated by the arrows P+ and P2. The housing l is formed with a recess 9 on its front side and at substantially the same level as the drive element 8 for the fingers, for example the thumb, of the hand holding the shaver. This makes it possible to hold the device very conveniently, with one or more fingers automatically being placed close to the drive element 8. In this way, the recess determines the position of the hand relative to the drive element.

In particular, when the driving element 8 slides in the directions of Pl and P2, r> is possible, the driving element 8 slides in the directions of P2 and Pl through the fingers in the elongated recesses 9 extending vertically. Necessary reaction forces substantially directed in the directions of P + and P2 can be easily transmitted to the housing.

In particular, when three shaving units 3 arranged in a triangular shape are used, as shown in FIG. 1, the shaving head 2 becomes rather bulky. Holding the device in this position is tiring. This drawback is alleviated by providing a recess 9 at a location between the shaving head 2 and the housing part 4, as indicated by the dashed line 10. However, it should be noted that the invention can also be used with shavers having more than 23 shaving units or other types of shaving units.

The shaving device shown in FIG. 4 has a housing 11 with a shaving head I" 12, the shaving head of which has a stationary shaving element l3 and a reciprocating shaving element 14. The shaving element 14 is driven The vibrator motor 15 is housed within a housing 11, which also includes a motor electrical switch 16. A drive element in the form of a button 17 is provided.The rear wall 19 is formed with three elongated recesses 20.21 and 22 extending perpendicularly to the longitudinal direction of the housing. The arrangement of the sliding button and the depression is determined so that the sliding button 17 is always within the range of the thumb of the hand, no matter which depression is placed in the depressions 20, 21 and 22. It is also clear that it is possible to simultaneously place three fingers of the same hand on each of the .
