Definitions
- the invention relates to a dry shaving apparatus with at least one electric motor arranged in a housing and with a pivotably mounted shaving head and an adjustable long hair cutting system and with an actuation switch.
- a dry shaver of the type mentioned is known from DE 37 26 354 C2.
- This dry shaving apparatus has a shaving head which is pivotably mounted about a pivot axis Z, and at least one actuating switch provided on the housing for starting up the cutting system provided in the shaving head and for controlling the pivoting shaving head into a predetermined latching position in order to connect one at the front of the dry shaving apparatus below of the shaving head provided, in the vertical direction slidably mounted in a trimming position long hair cutting system.
- a cam track with at least one latching position between two stops delimiting the pivoting range of the shaving head and a plunger acting on the cam track, which is directly or indirectly coupled to the actuation switch, is provided in the frame of the shaving head.
- JP-4-253 888 discloses a dry shaving apparatus of the type mentioned at the outset with a transmission device which is formed by a gearwheel arranged on the motor shaft of an electric motor and a toothed rack coupled thereto.
- the electric motor which is permanently connected to the LHS system, moves up and down in the vertical direction together with the gearwheel on the rack attached to the housing, depending on the direction of rotation. Carrying the electric motor within the razor housing during transport of the LHS system into and out of an operating position requires a corresponding free space and consequently an enlargement of the dry shaving apparatus in its entirety.
- an electric motor with a speed range of approx.
- a dry shaving apparatus with an LHS system which can be pivoted out of the housing of the dry shaving apparatus in an operating position by means of an electric motor and a gear mechanism and can be pivoted back into the housing by the latter .
- the gear devices provided for this purpose consist, for example, of a combination of at least one gearwheel with an arc-shaped toothed rack with internal and external teeth or of several gearwheels with different diameters.
- the object of the invention is to enable and facilitate the transport of an adjustable long hair trimmer system in and out of at least one operating position in a dry shaving apparatus of the type mentioned, in particular the switching path of the actuation switch required for this and the actuating force to be applied to the user reduce.
- this object is achieved in a dry shaver of the type mentioned in claim 1 by the features specified in the characterizing part of this claim.
- An important advantage of the invention is that the user is provided with a dry shaving apparatus in which the swivel-mounted shaving head is automatically moved from an arbitrary swivel position into a swivel position releasing the travel path of the long-hair cutting system and then only by actuating an actuation switch the adjustable long hair cutting system is transported unhindered by the shaving head into at least one operating position suitable for cutting long hair and that by means of a further actuation of the actuation switch, the long hair cutting system is transported back into a further operating position or into a switching position in which the shaving head can then be freely pivoted again.
- the combination of linear feed gear device and speed reduction gear carried out according to the invention ensures a particularly easy and sensitive adjustment or adjustment of the feed movement both for the pivotably mounted shaving head and for the adjustable long hair cutting system.
- actuation switches In particular actuation switches with extremely short switching travel, such as e.g. Pressure switch or rocker switch or without a switching path such as Sensor switches are provided.
- two electric motors are provided in the housing, one of the electric motors being associated with the transmission device.
- a major advantage of this measure is that the two electric motors can each be matched to a specific application with regard to the power, in particular the speed and the size.
- this intended use of two electric motors according to the invention simplifies and facilitates the accommodation of the respective components coupled to this electric motor, such as for driving the cutting elements of the intended cutting systems, on the one hand, and the gear mechanism for the adjustable long-hair cutting system and the pivoting one
- the shaving head within the volume of the housing of the dry shaving apparatus.
- the available volume of space can be optimally used, so that the desired or required handy size of a dry shaver can be maintained.
- the two electric motors can be activated by means of a common actuation switch. Accordingly, the switching elements required for switching the electric motors on and off are largely integrated in the actuating switch. According to a further advantageous embodiment of the invention, it is provided that an actuation switch is assigned to each electric motor. In the course of the use of the dry shaving apparatus, this embodiment ensures that the long hair cutting system is directly switched on or off in relation to the short hair cutting system and thus optionally the simultaneous use or separate use of the short hair cutting system and the long hair cutting system by actuating the actuation switch provided for this purpose.
- the arrangement of two actuating switches, each for a special function is regarded by many users of such devices as a measure which makes handling easier.
- the linear feed mechanism is formed by a threaded spindle having two thread runs and two drive rods, one drive rod being coupled to the pivoting shaving head via a swivel gear and the other drive rod being coupled to the long hair cutting system by means of a slide.
- the feed speed of the two drives is initially dependent on the speed of the electric motor and the pitch of the threads of the threaded spindle and, in a preferred embodiment, is also dependent on the gear ratio of the speed reduction gear. After that, the feed rate can be adapted and changed very simply and easily to the respective application in a variety of ways.
- a preferred embodiment of the invention is characterized in that the travel of the drive sticks can be limited indirectly or directly by stops.
- the swivel gear is formed from a rack adjustable by a drive rack and a gear wheel mounted on the chassis.
- a particularly simple adjustment of the pivotably mounted shaving head to a pivoting position which releases the extendable long hair cutting system is accomplished in that the gearwheel rotatably mounted on the chassis acts on an adjusting lever provided on the shaving head frame by means of a control lever. Precise control of the actuating movement of the pivotably mounted shaving head and of the long hair cutting system, which can be transported into an operating position, by means of the drive sticks on the threaded spindle is ensured in that the threaded runs on the threaded spindle are separated from one another by a freewheeling area for the drive sticks. According to this measure, each drive rod is assigned a thread run on the threaded spindle, it being possible for the pitch of the respective thread turns to be either the same or different.
- the drive sticks are acted upon by at least one spring element.
- the spring element is provided between the drive sticks. This relatively simple measure ensures the threading of a drive shaft located in a freewheel area by the pressure exerted by the spring element, which is increasingly influenced by the further drive shaft moving on the other threaded spindle.
- the spring element is formed by an elastic lever arm.
- the elastic lever arm is provided on one of the drive rods. Accordingly, in a further embodiment of this embodiment, a stop for the elastic lever arm is provided on the other drive shaft.
- a spring element designed as a compression spring is provided between the stop and the drive shaft.
- a spring element is preferably designed as a tension spring and fastened to the drive shaft and to the slide.
- the drive shaft which is movable in the vertical direction V between two freewheel areas on the housing, comes out of engagement with the upper threaded run.
- the long hair cutting system is fixed on the slide.
- the long hair cutting system is pivotably arranged on the slide.
- a plunger is mounted on a housing wall of the long hair cutting system in such a way that a pivoting movement of the long hair cutting system with the housing wall is ensured when the plunger abuts against a stop on the chassis and subsequent further movement of the slide in the vertical direction.
- the swivel range of the long hair cutting system can be up to 180 °.
- the swivel range of the long hair cutting system from 90 ° to 180 °, such a visible positioning of the long hair cutting system can be achieved earlier in comparison to a fixed long hair cutting system, that is to say with a shorter adjustment path of the slider carrying the pivotably mounted long hair cutting system.
- the plunger is slidably guided in an elongated hole provided on the housing wall.
- the plunger is slidably guided on the slide.
- the housing wall is pivotally mounted against the action of a spring.

- the short hair cutting systems K1 and K2 can be arranged in the shaving head SK or in the shaving head frame 4 both relatively rigidly and movable relative to one another.
- a U-shaped recess 7 is formed in the front of the housing shell 1, into which a slide 8 carrying a long-hair cutting system L1 and an actuating switch 9 are arranged so as to be movable in and against a vertical direction V.
- the long-hair cutting system L1 can, according to one embodiment, be fixedly arranged on the slide 8 - see FIG. 1 - or according to a further embodiment on the slide 8 can be pivoted about pivot bearings 24, 25 provided thereon - see FIGS. 2 to 9 -.
- the actuating switch 9 is designed, for example, as a slide switch. However, other types of actuating switches, for example pressure switches, rocker switches, sensor switches or rotary switches, can also be provided for activating one or more electric motors 27 arranged in the housing. At least one switching link 13 with latching positions 10, 1 1 and 1 2 is provided on the actuating switch 9.

By means of an opening made in the housing 3 according to FIG.
- one of the switching links 13 and one of the spring-elastic spring arms 15 are shown visibly, for example in the OFF position of the actuating switch 9.
- the slide 8 with the long hair cutting system L1 is located in an area below the pivotably mounted shaving head SK or shaving head frame 4, so that the cutting systems provided in the shaving head SK or shaving head frame 4 are used, like short hair cutting systems K1 and K2 and / or a combination of short hair cutting systems with a long hair cutting system is unhindered by the long hair cutting system L1.
- FIGS. 2 to 4 show a side view of the dry shaving apparatus according to FIG. 1, with a shaving head SK with a shaving head frame 4 with a shaving head frame 4, which is not visible, above the housing shells 1 and 2 of the housing 3, on the one hand on the support arm 50 and on the other hand on another support arm 51, whose end cheek 5 is increasingly tapered from the housing 3 to the outer contours of the cutting systems provided.

- the operating position B intended for a long hair cutting system L1 for trimming purposes lies above a cutting system which projects out of the shaving head frame 4 at the top vertex of one or more, e.g. Short hair cutting system K1 and K2 and / or an additional long hair cutting system provided tangent T.
- the long hair cutting system L1 which can be transported from the switch position into the operating position B, is arranged on the slide 8 so that the pivoting angle W of the cutting knives 17 and 18 of the long hair trimmer system L1 and the housing wall 19 transporting them can be up to 180 °.
- Utilization of the swivel angle range W from 90 ° to 180 ° ensures an optimal view of the cutting area of the long hair cutting system L1 in a mirror in the operating position B.
- the use of the swivel angle range W from 90 ° to 180 ° reduces the travel of the slide 8 carrying the long hair cutting system L1 from the switching position to the operating position B above the tangent T.
- FIG. 2 shows the dry shaving apparatus according to FIG. 1 with an actuation switch 9 in the OFF position.
- the first switching stage ON only serves to start up the cutting system or the cutting systems provided in the pivotably mounted shaving head SK, while the second switching stage, see FIGS. 3 and 4, activates an electric motor arranged in the housing 3, which, via a gear mechanism, activates the pivoting position of the shaving head SK and triggers the transport of the long hair cutting system L1 into the operating position shown in FIG. 4 - see also FIGS. 5 to 7.
- a gradual return of the actuation switch 9 initially brings the long hair cutting system L1 back from the operating position B to the position shown in FIG.
- the in the cutting systems provided to the shaving head SK can be used in this switch position of the actuating switch and can only be put out of operation by a subsequent switching operation from the switch position ON to the switch position OFF.
- FIGS. 2 to 4 shows a side view of the housing 3 of the dry shaving apparatus with an opening provided in the walls of the housing shells 1 and 2 and the shaving head support 52 through which the components provided in the housing 3 for the pivoting of the shaving head SK are partially visible .
- a gear 53 with a control lever 54 is pivotably mounted on the chassis 20. The teeth of the gear 53 are in engagement with a toothed rack 56, the control lever 54 assuming an opposite position from a stop 57 provided on the chassis 20 in the OFF position of the actuation switch 9.
- An adjusting lever 55 is provided on the shaving head SK or its shaving head frame 4 in such a way that, in the OFF position and also in the first ON position of the actuating switch 9, it takes approximately the same distances from the stop 57 on the one hand and the control lever 54 on the other hand.
- an electric motor 27 is activated, which transports the rack 56 in the vertical direction V via a gear device G provided in the housing 3 - see FIGS. 5 to 7 - until the with the gear rack 56 engaged gear 53 brings the control lever 54 to bear against the stop 57.
- the control lever 54 comes into contact with a cam 58 against a control surface 59 on the adjusting lever 55 and thus pivots the shaving head SK about the pivot axis Z until the control lever 54 comes into contact with the stop 57.
- the shaving head SK reaches a swivel position which ensures unimpeded transport of the long hair cutting system L1 into an operating position B located above the tangent T - see FIG. 4 -.
- FIG. 5 shows the components of a dry shaving apparatus with a pivotably mounted long hair cutting system L1 after removal of all components of the shaving head SK of the shaving head carrier 52 and the housing shells 1 and 2 of the housing 3 from a chassis 20.
- a slide 8 On the chassis 20 there is a slide 8 by means of guide elements 60, 61, 62 and 63 slidably guided.
- the slide 8 In the region of the long hair cutting system L1, the slide 8 has side walls 22 and 23, on which the housing wall 19 of the long hair cutting system L1 is pivotably mounted by means of pivot bearings 24 and 25.
- the double-armed drive lever 26, which is pivotably mounted on the slide 8, is used to transmit an oscillating movement emanating from an electric drive to an oscillating cutting knife 17 or 18 of the long-hair cutting system L1.
- an electric motor 27 which can be activated by an actuating switch 9 - see FIG. 1 and which is coupled here, for example via a speed reduction gear 28, to a gear device G, namely a linear feed gear device 29.
- the linear feed gear device 29 consists of a threaded spindle 30 with two thread runs 64 and 65, which are separated from one another by a freewheeling area 66, and the drive rods 21 and 31.
- a freewheel area 67 and 68 is provided at the ends of the threaded spindle 30, for example.
- the threaded spindle 30, which is coupled to the speed reduction gear 28 on the one hand, is supported on the end at a stop 80 provided on the chassis 20. Contrary to the stop 80, a stop 81 is provided on the chassis 20 which limits the travel of the driving stick 21.
- the drive rack 21 is assigned to the threaded barrel 64 and is coupled to the gear 53 via the rack 56.
- a stop 69 is provided which, in the course of the movement of the headstock in the vertical direction V, comes to rest against the resilient lever 34 of the free-motion area 66 of the headstock 31 - see FIG. 6 -.
- the drive rod 31 from the freewheel region 66 is in engagement with the brought diaper 65 of the threaded spindle 30.
- the headstock 31 is coupled to the slide 8 via a fork 32 and a coupling element 33.
- the fork 32 and the coupling element 33 serve to facilitate assembly or coupling of the drive shaft 31 with the threaded spindle 30 and the slide 8.
- the drive shaft 31 moves in the vertical direction V the stop 80 provided on the chassis 20 into the freewheel area 67 provided there and acts on a compression spring 71 surrounding the threaded spindle 30, the spring pressure of which, when the direction of rotation of the threaded spindle 30 is reversed, causes the drive shaft 30 to be threaded out of the freewheel area 67 onto the threaded run 65 .
- the thread on the threaded spindle ends directly at the stop provided on the chassis, which is therefore at least provided as a stop or stop element, optionally as a contact switch for the drive rod.
- a support element 39 is integrally formed on the wall 49 of the slide 8 connecting the side walls 22 and 23.
- a spring 40 designed as a torsion spring is arranged on the carrier element 39, the spring ends of which rest on the one hand on the housing wall 19 and on the other hand on a wall of the slide 8.
- a coupling piece 41 is integrally formed on the housing wall 19 adjacent to the carrier element 39.
- An elongated hole 42 is formed in the coupling piece 41, into which a coupling bolt 44 provided on a tappet 43 engages in a sliding manner - see FIGS. 8 and 9. Starting from the coupling piece 41, the plunger 43 extends in the direction of the electric motor 27.
- Fig. 9 shows a longitudinal section through the upper part of the chassis 20 and through the OFF position, i.e. Long hair cutting system L1 in the pivoted-in state.
- a stop 46 for the plunger 43 is formed on the chassis 20, the interaction of which with the stop 45 of the plunger 43 is explained in more detail with reference to FIGS. 7 and 8.
- the embodiment according to FIG. 9 also shows cutting knives 17 and 1 8 of the long hair cutting system L1 coupled to the housing wall 19 and the coupling piece 41 provided with the elongated hole 42 and the plunger 43 which engages in the elongated hole 42 via the coupling bolt 44.
- FIG. 7 shows the pivoted long hair cutting system L1 in the pivoted-out state, with the side walls 22 and 23 of the slide 8 and the swivel bearings 24, 25 provided thereon for the pivotably mounted housing wall 19 and the coupling of the coupling piece 41 with the being better shown Tappet 43, the arrangement of the spring on the carrier element 39, the cutting knives 17 and 18 of the long hair cutting system L1 are only partially shown.
- the function of the long hair cutting system L1 which can be transported from a switch position into an operating position B will now be explained in more detail with reference to FIGS. 7, 8 and 9.
- the speed of the motor shaft of the electric motor is transmitted to the threaded spindle 30 via the speed reduction gear 28 in accordance with the gear ratio provided there and sets it in a corresponding rotary movement.
- this rotary movement including the tensile force of the tension spring 70, the drive shaft 21 is threaded onto the threaded barrel 64 and then moves on the threaded barrel 64 in the vertical direction V into the freewheeling region 66.
- the stop 69 of the drive shaft 21 acts on the spring-elastic lever 34 of the drive shaft 31 and, via the increasing spring tension of the spring-elastic lever 34, causes the drive shaft 31 to be threaded from the freewheel area 66 onto the threaded barrel 65.
- the force of the spring 70 which is fastened on the one hand to the slide 8 and on the other hand to the drive shaft 21, keeps the control lever 54 in contact with the stop 57 in the course of the further movement of the slide 8 in the vertical direction.
- the drive shaft 31 is moved in the direction of the freewheel region 67 or stop 80 in accordance with the pitch of the threads 37.
- the stop 45 on the tappet 43 comes to bear against the stop 46 provided on the chassis 20 - see FIGS. 8 and 9.
- the pivotably mounted housing wall 19 of the long hair cutting system L1 still assumes the pivot position shown in FIG. 9.
- the threaded spindle 30, which is still rotating, transports the drive shaft 31 and thus the slide 8 further in the vertical direction V to the operating position B - see FIG.
- the resulting tensioning of the compression spring 71 can be used, for example, as a contactor for the electric motor and consequently cause an interruption in the circuit and thus shutdown of the electric motor 27.
- the compression spring 71 which is under compressive stress, can also act as a load switch in such a way that the electric motor 27 is switched off due to an increased current consumption of the electric motor 27.
- the long hair cutting system L1 is returned to the switching position OFF by actuating the actuation switch 9 again, for example by returning it from the locking position 1 2 to the locking position 1 1 - see FIG. 1 -. With this switching operation, a reversal of the direction of rotation of the electric motor 27 is also effected.
- the drive shaft 31 with the spring-elastic lever 34 executes an actuating movement from the stop 80 to abutment against the stop 69 of the drive shaft 21 and, as already described, causes the drive shaft 21 to be threaded onto the threaded barrel 64 and thus transported into the freewheel area 68
- the control lever 54 pivots back into the position shown in FIG. 2 and releases the pivotably mounted shaving head SK so that it can pivot back and forth freely in the intended pivot range.
- the long hair cutting system L1 is now below of the pivotably mounted shaving head - see Fig. 2 and 3 -.
