Definitions

  • the invention relates to a dry shaving apparatus with a short hair shear part, a long hair shear part arranged on a first slide switch and displaceable from a rest position into an operating position near the short hair shear part, which is coupled in the operating position to the drive of the dry shaving apparatus (brochure Braun micron 1976).
  • Such dry shavers are currently on the market.
  • the slide switch carrying the long-hair shear part is part of a double-function switch. It can first be shifted from its rest position into a first switch position in which the dry shaver is switched on. The dry shaver remains switched on if it is moved beyond the switch-on position.
  • the long-hair shear part is shifted into the operating position and coupled to the drive of the dry shaving apparatus.
  • This design of a dry shaver has the advantage that when the dry shaver is switched off, the long hair section is always disengaged. As a result, the long-hair shear part need not run unnecessarily when the dry shaver is switched on and only the short-hair shear part is used. Since the long-hair shear part is relatively stiff, the dry shaver consumes a relatively large amount of electrical energy when it is switched on. In the case of battery-operated dry shavers, the unnecessary running of the long hair part leads to a relatively rapid depletion of the batteries. Apart from this, there is also unnecessary wear if the long-hair shear part runs along without it being required.
  • the long-hair clipper part should be in a rest position as long as it is not in use and in which it does not interfere with the use of the short-hair clipper part.
  • the slide switch with the long-hair shear part is moved from its rest position towards the shaving head.
  • the long-hair shear part inevitably approaches the short-hair shear part and can interfere with its use.
  • the invention has for its object to develop a dry shaver of the type mentioned, in which the long-hair shear part can remain in its optimal rest position when only the short-hair shear part is used, but in which it is still possible to switch on and off the dry shaver without changing hands and engage or disengage the long hair shear part.
  • the first switch slide is assigned a second switch slide which can be displaced relative to the first switch slide for switching the dry shaving apparatus on and off.
  • the slide switch with the long-hair shear part need not be moved, so that the long-hair shear part can remain in its optimal rest position and therefore does not interfere with the use of the short-hair shear part.
  • the slide switch for switching on and off is directly assigned to the slide switch with the long-hair shear part, the long-hair shear part can be switched on if necessary without the user having to change his grip.
  • An advantageous embodiment of the invention is that the second slide switch is arranged on the first slide switch for switching the dry shaving apparatus on and off.
  • the first slide switch must be of considerable size, since it is not only a slide switch but also a holder for the long-hair shear part. Therefore, the slide switch can be easily placed on it for switching on and off.
  • This embodiment of the invention is particularly advantageous in terms of production technology, since the housing of the dry shaving apparatus does not have to be formed at different points in accordance with the requirements of the second slide switch.
  • Another favorable embodiment of the invention consists in that the second slide switch for switching the dry shaving apparatus on and off can be displaced transversely to the first slide switch.
  • each slide switch can be actuated independently of the other, but both slide switches can be actuated by, for example, placing the thumb on the second slide switch. This makes switching extremely convenient. On top of that, you can see at a glance whether the long hair section is in the operating position or the rest position, so that it can no longer be expected that the long hair section will always remain switched on for convenience or forgetfulness.
  • a further advantageous embodiment of the invention is that the second slide switch for switching the dry shaving apparatus on and off can be moved in the same direction as the first slide switch.
  • the second slide switch can be designed in such a way that, after reaching the switch-on position, it takes the first slide switch with it, so that by moving the second one Switch slide initially only this itself relative to the first slide switch, but with a larger displacement path, the first slide switch is moved together with the second slide switch. In the opposite direction, the second slide switch is moved beyond the switch-off position, so that the first slide switch with the long-hair shear part can return to its rest position.
  • This arrangement of functions makes the arrangement according to the invention easy to handle. It is also advantageous because the shifting link moves in the longitudinal direction, i.e. in the shifting direction and not transversely to it. For this reason, the switching gate is easier to accommodate in the housing of the dry shaver.
  • the first slide switch with the long-hair shear part is held in its two end positions by resilient means.
  • the manually required displacement path of the first slide switch becomes smaller because after it has overcome its dead center it automatically reaches its end position. This ensures that in the operating position the long-hair shear part is completely coupled to the drive of the dry shaving apparatus, since the first slide switch always reaches its end position fully due to its jumping characteristics.
  • Another favorable embodiment of the invention consists in that the second slide switch can be moved between two stops of the first slide switch when the dry shaving apparatus is in and out. As long as the dry shaver is only switched on or off, the position of the first slide switch and thus the position of the long-hair shear part does not change. However, if the second slide switch is moved beyond the display or exhibition, it inevitably takes the slide switch along with stops, so that the long-hair shear part can be moved either in the operating position or in the rest position.
  • a further advantageous embodiment of the invention consists in that the first slide switch is prestressed in the direction of its rest position by compression springs. This configuration means that when the dry shaving apparatus is switched off, the first slide switch and thus also the long-hair shear part are inevitably pushed back into its rest position. The long-hair shear part cannot run if it has not been pushed back into the rest position after use for convenience or forgetfulness.
  • the compression springs can either be arranged in the shaving head frame or in the housing of the dry shaving apparatus.
  • the second slide switch has latching devices for latching in the insertion and exhibition and in the operating position of the long-hair shear part. These catches enable the second slide switch to hold the first slide switch in the operating position, so that the compression springs cannot automatically push it back into the rest position.
  • the second slide switch is designed as a switching link with a plunger actuating an electrical switch, and this switching link is inserted into a recess in the first switch slide.
  • a further very advantageous embodiment of the invention is characterized in that the first slide switch has two locking points which define the setting and setting of the second slide switch, into which the second slide switch or the switching link can be locked with a catch, and that one in the housing of the dry shaving apparatus Stop edge is provided, by means of which the catch is prevented from disengaging from the switch-on catch, as long as the first slide switch or the shift gate is above its rest position.
  • Fig. 2 shows in detail a first embodiment of the slide switch 1, which carries the long-hair shear part 2.
  • the slide switch 1 By moving this slide switch 1 in the direction of arrow 3, the long-hair shear part 2 is shifted out of a rest position into an operating position in which it is coupled to the drive of the dry shaving apparatus and thereby follows.
  • a second slide valve 5 is arranged transversely to it in the direction of arrow 4. This is rigidly connected to a switching link 6, which is in the assembled state of the parts shown in Fig. 1 within the housing A of the dry shaving apparatus.
  • the switching gate 6 has a plunger 7, with which an electrical switch (not shown) is actuated in the exhibition of the slide switch 5.
  • the slide switch 5 is first shifted towards the left in the direction of part 4 in the drawing.
  • the dry shaving apparatus is switched off again by moving the second switching slide 5 to the right, as seen in the drawing.
  • the second slide switch 1 is moved in the direction of the arrow 3. This can be done by pressing the second slide switch 5 in the direction of part 3 with the thumb.
  • the embodiment according to FIG. 3 differs from that according to FIG. 2 in that the second slide switch 5 can be displaced in the same direction as the first slide switch 1 relative to the first slide switch. As a result, the switching link 6 can also be displaced exclusively in the switching direction, which is favorable for its arrangement in the housing of the dry shaving apparatus. Arrows 8 and 9 in FIG. 3 illustrate the displaceability of both slide switches 1 and 5 in only one common direction. The operation of the arrangement according to FIG. 3 corresponds to that according to FIG. 2.
  • first slide switch 1 on which a long-hair shear part 2 is attached.
  • the switch slide 1 has on its outside a recessed surface 11 on which the second switch slide 5 is arranged. It is not shown how the second slide switch 5 reaches through the first slide switch in order to be able to actuate an electrical switch with a plunger or the like.
  • the recessed surface 11 creates a stop 12 against which the slide switch 5 can be moved after it has reached the switched-on position of the dry shaving apparatus.
  • the first switch slide 1 projects into a slot 14 of the second with a pin 13, which has the function of a stop for the first switch slide Switch slide 5.
  • the upper limit of the elongated hole 14 seen in the drawing is able to move against the pin 13 when the second switch slide 5 is moved downward, thereby displacing the first switch slide 1 as well.
  • the length of the elongated hole 14 and the distance between the second slide switch 5 and the stop 12 must be dimensioned such that the second slide switch 5 can be moved freely from its switched-off position to its switched-on position without displacement of the first slide switch 1.
  • FIGS. 4 and 5 it is possible to switch the dry shaving apparatus on and off without pushing the long-hair shear part 2 back into its rest position.
  • two compression springs 17, 18 are arranged in the shaving head frame B, which bias the first slide switch 1 in the direction of its rest position.
  • the second slide switch 5 is not arranged on the first slide switch 1 but rather somewhat below the first slide switch 1 on the housing A of the dry shaving apparatus.
  • a game 19 is provided between the first slide switch 1 and the second slide switch 5, after overcoming which the second slide switch 5 takes the first slide switch 1 with it. This play is so great that the second slide switch can be used to move from the off position to the on position without actuating the first slide switch.
  • locking devices which hold the slide switch 1 in its upper position so that it cannot return automatically to its rest position.
  • FIG. 8 differs from that according to FIGS. 6 and 7 initially in that the compression springs 17, 18 are arranged at the lower end of the first slide switch 1 and thus in the housing of the dry shaving apparatus.
  • the second slide switch 8 shows two latching devices 20, 21 and 20 ', 21' on each side of the second slide switch 5.
  • the first latching device has two latching points 22, 23 lying close to one another, by means of which the insertion and removal of the second slide switch 5 is fixed.
  • the second locking devices 21, 21 ' are at such a distance from the first locking devices directions 20, 20 'that the operating position of the first slide switch 1 and thus the long-hair shear part 2 is determined by them.
  • the holding force of the latching device 21, 21 ' must be so great that the compression springs 17, 18 do not automatically move the first slide switch 1 back into its rest position.
  • the first slide switch 1 is pushed up in that the second slide switch 5, after overcoming a game, comes up against a stop 24 of the first slide switch 1.
  • the embodiment according to FIG. 9 is made in such a way that, despite the arrangement of two slide switches, a unitary component is created which is as flat as possible.
  • the second slide switch 5 is also a shift gate.
  • the first slide switch has a recess 25 with longitudinal grooves 26 into which the second slide switch 5 engages with projections 27.
  • the second slide switch as in the previously described embodiments, can be displaced in the grooves 26 relative to the first slide switch with its projections 27.
  • first switch slide 1 can also be offset from the inside of the dry shaving apparatus, so that the switch link 6 does not protrude beyond the thickness of the first switch slide.
  • the switching gate 6 is connected via a pin 28 to the second slide switch 5 on the outside of the first slide switch 1. This pin 28 is guided through an elongated hole 29 of the first slide switch.
  • FIG. 11 shows a part of the switching gate 6, which is displaceable relative to the first switching slide 1 by the second switching slide, which is not shown and is firmly connected to the switching gate 6.
  • the first slide switch has two latching points 30, 31 arranged close to one another. In the position of the components shown, the switching link 6 engages with a latch 33 arranged on an arm 32 in the latching point 31, which defines the switch-off position of the dry shaving apparatus. By moving the switching link 6 in the drawing, as seen above, the catch 33 comes out of the catch point 31 and into the catch point 30, which marks the switch-on position of the dry shaving apparatus.
  • the catch 33 remains in the locking point 30 and thereby takes the first shift slide 1 upward, so that the shaving head part comes into the operating position. Likewise, the catch 33 takes the first slide switch with the shaving head part when the shifting gate 6 is pushed back into its rest position before it disengages from the rest point 30 and returns to the rest point 31 and thereby switches off the dry shaving apparatus.
  • a strip 34 is arranged fixed to the housing, the stop edge 35 facing the arm running so closely parallel to the arm 32 above the locking point 30 that it is unable to move radially outward from the locking point 30.
