Definitions
- the invention relates to a dry shaver, the type specified in the preamble of the main claim.
- a dry shaver of the type mentioned is known from US 2,339,677.
- the shaving head which is formed from a shaving head frame, as well as an upper knife and lower knife, is arranged on an upper housing surface of a housing such that it can be moved back and forth transversely to the direction of movement of a lower knife driven in an oscillating manner in the longitudinal direction.
- a double eccentric is provided on the rotary shaft of an electric motor fixedly arranged in the housing for transmitting the drive movement to the lower knife on the one hand and to the shaving head on the other hand.
- the masses of shaving head, bedknife and double eccentric which can be moved back and forth by drive elements in different directions, cause excessively strong vibrations, which are noticeable to the user in terms of volume and handling.
- a dry shaver of the type mentioned is also known from DE-GM 1 71 1 665.
- the drive element of the electric drive is also via gear elements, such as. B. gear transmission, or a double eccentric or a double-armed lever, both with the lower knife and with the shaving head equipped with an upper knife to set the lower knife and in addition the complete shaving head in motion.
- gear elements such as. B. gear transmission, or a double eccentric or a double-armed lever
- flywheel weights assigned to the electric drive inevitably require an increase in the power output of the electric drive, which is directly due to an increase in the price of the electric drive and, in addition, in the case of a dry shaving apparatus equipped with rechargeable storage cells, through a higher consumption of storage power and consequently a lower number of shaves per charge that makes memory cells noticeable.
- the invention has for its object to improve a dry shaver of the type mentioned.
- This measure according to the invention is characterized by a large number of advantages.
- the electric drive When the electric drive is started up, the electric drive, from the masses set in motion by the drive element and also from the friction taking place between the existing cutting elements, experiences an oscillating excitation at least in each case counter to the direction of movement of one or possibly several cutting elements.
- This oscillating excitation which is transferred from the electric drive to the razor housing in the previously standard rigid attachment of an electric drive to the razor housing and consequently leads to unpleasant vibration and a loud noise there, is caused according to the invention by the oscillatable mounting of the electric drive , not transferred to the housing, but initially remains with the electric drive and causes it to swing about at least one axis.
- the electric drive thus follows the forced oscillating movements without any significant effect on the housing of the dry shaving apparatus.
- the threaded hair is carried along by the cutting element designed as a lower knife, the cut being made against the edge of the hair entry opening in the cutting element designed as an upper knife.
- the upper knife moves towards the lower knife and thus shortens the hair displacement path of a hair that has penetrated through the hair entry opening during the cutting process, as a result of which the hair is cut shorter.
- the cutting performance of the dry shaver is thus significantly improved. Due to the high vibration frequency of the shaving head, a lower sliding friction of the cutting element on the skin is also effective.
- a major advantage of the invention is that the oscillating excitation emanating from the movable masses is not - as is known - on the housing of the dry shaving apparatus - see DE-GM 1 71 1 665 - but via the oscillatable mounting of the electric drive on the movable shaving head is transferred.
- the energy of the oscillating excitation is thus diverted from a location in the housing where disruptive effects occur to a location where this energy can be used advantageously.
- the electric drive is not required to have any drive power for this shaving head.
- At least the shaving head and the electric drive are mounted as an oscillating mass so as to be oscillatable about at least one common oscillation axis.
- the oscillating mass is obtained by including Vibrating mass of the electric drive and all components that can be set into vibration by the vibrating movements of the electric drive, such as, for. B. shaving head, support arms, bearing cage, gimbal, swing frame, support frame, spring element and swing bridge for a cutting unit and / or by attaching additional vibration masses is formed.
- the electric drive with the components that can be set in vibration is mounted so as to be capable of swinging about a first oscillation axis running transversely to the directions of movement of the drivable cutting element.
- a further advantageous embodiment of the invention is characterized in that the electric drive with the components which can be set in vibration is mounted so as to be capable of swinging about a second oscillation axis which runs parallel to the directions of movement of the drivable cutting element.
- the shaving head and the electric drive are mounted so that they can oscillate about the first oscillation axis and about the second oscillation axis by means of a cardanic suspension in the housing.
- the arrangement of a second oscillating axis crossing the first oscillating axis at right angles from the cardanic suspension of the electric drive and the shaving head in the housing of the dry shaving apparatus enables the reaction forces arising from dynamic processes to keep the first and second oscillating axes away from the housing and also for oscillating movements of the shaving head to be used both in the directions of movement A and B and in the directions of movement C and D.
- the oscillating element can be coupled to the oscillating support frame via the bearing cage or a housing part.
- a driver device is provided for coupling the bearing cage or the housing part to the support frame.
- the electric drive is mounted so that it can oscillate about an oscillation axis.
- a preferred embodiment of the invention is characterized in that the shaving head is mounted so that it can vibrate in the housing by means of at least one oscillating element.
- the oscillating element is formed by support arms having joints.
- the oscillating element is formed by a housing part.
- the oscillating element is formed by an oscillating gimbal frame, a bearing cage oscillatingly mounted in the gimbal, an oscillating frame and by support arms.
- a significant improvement in the cutting performance of the cutting elements and a significant reduction in the vibration of the housing of the dry shaving apparatus can be achieved in that the oscillation axis is provided running through the center of the impact of the oscillating mass.
- the center of impact of the vibrating mass is the place around which the motor would swing if a drive unit running at nominal speed - electrical drive and driven elements - could oscillate freely.
- the bearing forces to be applied for the vibrating mass, here for the drive unit reach their minimum, as a result of which the undesired housing vibration is reduced to a minimum.
- the vibration axis is provided at a distance from the center of the vibration mass.
- the shaving head can be driven in the directions of movement A and B of the drivable cutting element by the oscillating movements of the electric drive.
- this embodiment it is provided that the shaving head is driven by the electric drive in a manner capable of oscillating in the opposite direction to the reciprocating movements of the cutting element. This measure leads to better cutting performance by shortening the hair displacement path in the hair entry openings of the upper knife.
- the shaving head can be driven transversely to the directions of movement A and B of the drivable cutting element in the directions of movement C and by the oscillating movements of the electric drive.
- An improvement in the cutting performance of the cutting elements is achieved according to the invention in that different vibration amplitudes are provided for the shaving head and the movable cutting element.
- This measure ensures, for example, an optimal design and adaptation of movable cutting elements compared to fixed cutting elements, taking into account the diverse geometries of hair entry openings in cutting elements which become effective as the upper knife.
- a significant advantage according to the invention is also achieved in that the vibration amplitudes of the shaving head and / or cutting element can be changed.
- the respective vibration amplitudes can be changed, for example, by changing masses that can be set in vibration or by displacing the vibration axis away from the center of the vibration mass.
- the oscillation amplitude can be determined by the cutting element and the oscillation amplitude of the shaving head can be matched to this. This measure ensures optimal coordination of interacting cutting elements.

- An optimal size of the swing path of the shaving head for a dry shaver type is in each case To be determined on a case-by-case basis, taking into account the respective formation of interacting cutting elements, in particular the geometries of the hair opening.
- the electric drive is mounted so that it can swing about the pivot axis by means of pivot bearings.
- the electric drive is largely decoupled from the inevitable vibration on the housing and at the same time ensures the use of this vibration energy for an advantageous oscillating movement of the shaving head.
- the electric drive is mounted so that it can vibrate in the housing of the dry shaving apparatus in such a way that it follows the imposed vibration without any significant effect on the housing.
- the housing part of the electric drive can be fastened in a bearing cage.
