Definitions

  • the invention relates to a multi-function switch for electrical devices for personal use, in particular hand-held and guided devices such as round styler, hair dryer or the like, in which an actuating part is arranged on the outside of the housing of the device, which has transmission elements a sliding member arranged in the housing is connected.
  • the switch by which the turn signal lights can be actuated alternately by means of a pivoting movement of a shift lever is designed in such a way that the flasher and an acoustic horn can be actuated by tilting the shift lever transversely to its pivoting direction.
  • the components to be actuated are arranged at various points and on top of that where, for reasons of haptics, an actuating part for a switch cannot be attached. In such cases, the switches must therefore be operated indirectly via transmission elements.
  • the switch actuation part has been arranged near the air outlet for tactile reasons.
  • a slide switch which is arranged near the motor of the RoundStyler, that is to say at a considerable distance from the outlet, is then switched by moving an actuating part.
  • the slide switch could be shifted in a straight line in three positions, with the device switched off in one position, both the heating and the blower switched on at full power in the second position and the heating and the half power blower switched on in the third position.
  • you could, for example, switch the heating and blower of a round styler independently of one another using a multiple function switch.
  • this has not yet been achieved because it was feared that such a measure, in particular the transmission elements that would become necessary, would make the multiple function switch so cost-prohibitive that a device equipped with it could no longer be sold economically.
  • the present invention is based on the object of developing a multi-function switch for electrical devices which can be actuated by means of an actuating part via long transmission elements, which can be produced cheaply and whose transmission elements take up little space in the electrical device.
  • the whistle of the marked multi-function switch according to the invention is that the first transmission element is able to transmit a movement of the actuating element in the axial direction to the sliding element without influencing the second transmission element, and that a rotary movement of the actuating part is transmitted from the first to the second transmission element, so that the component which can be actuated by the rotary movement can be adjusted without the sliding member being influenced.
  • the actuating part of the multi-function switch according to the invention can be easily moved axially with two fingers on the one hand, but on the other hand rotated independently of the respective axial position or even axially displaced and rotated at the same time. This results in a level of ease of use previously unknown for electrical devices.
  • the axial displacement of the actuating part can be used to control the blower output and the rotatability can be used to control the heating output.
  • only one rod which on the one hand takes up little space and on the other hand, can be shaped in the device between the actuating part and the sliding member and from the sliding member to the component which can be actuated by a rotary movement, can also be shaped in such a way that it is located in the overall installation parts of the Device bypasses.
  • Advantageous embodiments of the invention consist in that the component which can be actuated by rotary movement is a rotary resistor and the sliding member is a slide switch.
  • the invention is in no way limited to multiple function switches with slide switches and rotary resistance. That through.
  • a component that can be actuated in a rotational movement could also be used instead of a rotational resistance be a purely mechanical component, for example an air guide device, through which an air flow of a round styler is more or less concentrated.
  • a throttle device could also be adjusted so that an air flow is guided more or less through the inside of the round brush or outside. The rotatability of the actuating part would then have to be used exclusively for switching the device on and off and for changing both its heating output and its fan output.
  • a further embodiment of the invention according to which the actuating part is the housing is particularly advantageous in terms of construction and is haptically advantageous. of the device is a completely enclosing switching ring.
  • the switching ring can be locked in the switching positions of the multiple function switch by means of locking points in the housing. This ensures that the switching ring is almost always seated on the housing. Game of the components actuated by the switching ring and the transmission elements is then not noticeable on the switching ring, so that the device equipped with the multi-function switch according to the invention is easy to switch and its switching ring cannot cause rattling noises.
  • the advantageous Ausgestalt ⁇ ng characterized in claim 7 of the invention is particularly favorable when the rotary resistor and the slide switch are arranged particularly far from the switching ring in the device, for example in the case of round stylers on the circuit board near the Electric motor to drive the blower. Because the second transmission element engages in the eye of the first transmission element, the axial displacement of the two transmission elements relative to one another can easily be achieved without them being able to rotate relative to one another.

Then place half of the switching ring with the nose on the housing and hang the first transmission link there. The assembly is ended by adding the second half of the switching ring.
  • the slide switch of the multiple function switch has four switch positions. It is then possible to provide the first switch position for the display of the device, the second switch position for half the blower and heater output, the third switch position for full blower and heater output and the fourth switch position for full blower output and low heating output so that the rotatability for regulating the Heating output within the ranges set by the slide switch.

  • a slide switch 8 and a rotary resistor 9 attached.
  • the slide switch 8 is used to switch the round styler on and off and to switch on certain power levels of the blower and the heating.
  • Dre's rotating resistor has the task of sliding the heating power inside by resistance to control predetermined limits.
  • Both the slide switch 8 and the rotary resistor 9 can be actuated by a switching ring 10, which thus represents the common actuating part for slide switch 8 and rotary resistor 9.
  • the switching ring 1o is made of two halves that can be plugged together.
  • the switching ring 1o completely encompasses the housing 1 of the RoundStyler. On the outside it has knobs 11 to increase its grip. On the inside there is a leaf spring 12 on the switching ring 10 which can snap into a spherical recess 14 in the housing 1 with a spherical projection 13. These recesses 14 are, as the drawing shows, provided in four rows in the housing 1 and take up part of the circumference of the housing. As a result, the switching ring can be adjusted both axially and circumferentially from recess to recess.
  • the switching ring 1o furthermore has a nose 17 which projects through a housing opening 16 into the interior of the housing 1 and into which projects a first transmission element 18 which connects the switching ring 1o to the slide switch 8.
  • a second transmission element 20 leads from the rotary resistor 9 to the slide switch 8 and is coupled there to the first transmission element 18 in such a way that the transmission elements cannot be rotated relative to one another, but are axially displaceable relative to one another.

  • the transmission member 18 has at its other end a further radially bent section 24 which engages between two holding arms 25, 25 of the switching carriage 22 which form a clasp.
  • the bent section 24 forms an eyelet 27 with a square cross section between the holding arms 25, 26.
  • the second transmission element 2o is inserted through this eyelet 27 and through corresponding holes in the holding arms 25, 26. Its cross-section is dimensioned such that the second transmission element 2o is not. in the eyelet 27, however, can rotate in the holes of the holding arms 25, 26.
  • An axis of rotation 28 characterizes the geometric line about which the actuating part 1o and the two transmission members 18, 2o rotate.
  • the multiple function switch acts as follows. If the device equipped with the multiple function switch, that is to say the round styler in the exemplary embodiment, is to be switched on, then it is necessary to shift the switching ring 10 as seen in the drawing to the left. As a result, the first transmission element 18 also shifts to the left, as seen in the drawing, so that the eyelet 27 displaces the switching slide 22 and the slide switch 18 is actuated. Since the eyelet 27 engages with the second transmission element 20 with play and the holes in the holding arms 25, 26 also have play, the first transmission element 18 and the switching slide 22 can move on the second transmission element 20 without the second transmission element being influenced . If the switching ring 2D is rotated, then the first transmission element 18 also rotates about the axis 28.
  • both the eyelet 27 and the second transmission element 20 have a square cross section, the rotary movement is transmitted from the first to the second transmission element 20. As a result, the rotary resistor 9 is adjusted, so that the heating of the round styler controlled by it is changed in its output.
