Definitions
- the invention relates to a multi-function switch for electrical devices of personal need, in particular for hand-held and guided devices such as round styler, hair dryer or the like, in which an actuator is arranged on the outside of the housing of the device, which is both axially displaceable also arranged rotatably about an axis of rotation running in the housing and axially non-displaceably connected to a slide of a sliding member by means of a first transmission element, but pivotably connected about the axis of rotation of the actuating part, a second transmission element being non-rotatably but axially displaceably connected to a component which can be actuated by a rotary movement is.
- 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 different locations and on top of that where, for reasons of haptics, an actuator for a switch cannot be attached. In such cases, the switches must therefore be operated indirectly via transmission elements.
- a slide switch which is arranged near the motor of the hair dryer, that is to say at a considerable distance from the outlet, is switched by moving the actuating member by means of a transmission element bent from wire.
- the slide switch can be shifted in a straight line in three positions, with the device switched off in one position, both the heating and the fan switched to full power in the second position and the heating and the half-line fan switched on in the third position. It would of course be desirable if, for example, the heating and the blower of such a hair dryer could be switched independently of one another by means of a multiple function switch. So far, however, this has not been possible because an inexpensive solution has not yet been available.
- a multiple function switch of the type mentioned is described in DE-A-2 238 363. It is an electrical cord switch with an tubular cable entry opening, in which the actuator encompassing the cylindrical housing is connected to a slide switch via a first transmission element and to a rotary switch via a second transmission element, the first transmission element being connected to the actuator longitudinally displaceable and the second transmission member is rotatable with the actuator about the longitudinal axis of the housing.
- An independent switching of two functions is possible here.
- the transmission elements take up a lot of space in the tubular housing, which is missing for further installations.
- the present invention has for its object to provide a multi-function switch for electric hand hair dryer, in particular round styler, which can be actuated by means of an actuator via long transmission elements, and which is inexpensive to produce, whose transmission elements take up little space in the electrical device and whose actuator is arranged on the outer wall of the device housing can be.
- a multiple function switch for the lighting system of motor vehicles is also known (US Pat. No. 3,244,822), in which a first transmission element is non-rotatably but axially displaceably connected to the second transmission element, the first transmission element being fixedly coupled to the actuating element .
- This known multiple function switch has the disadvantage that the actuator is arranged in the elongated core axis of the two coaxially arranged transmission members, so that it is not suitable for installation in a tubular hair dryer, since in particular the actuator would interfere with the axial air flow.
- the axial displacement of the actuator can advantageously be used to control the heating power.
- the invention is in no way limited to multiple function switches with slide switches and rotary resistance.
- the component which can be actuated by a rotary movement could, for example, also be a purely mechanical component instead of a rotational resistance, for example an air guiding device through which an air flow from a round styler is more or less concentrated. Due to the axial displacement of the Actuating part could also be adjusted a throttle device, so that an air flow is more or less directed 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 power and its blower power.
- An actuating element which is a switching ring that completely encloses the housing of the device, is particularly advantageous in terms of construction and is haptically advantageous.
- the advantageous embodiment of the invention characterized in claim 1 is also particularly favorable when the rotary resistor and the slide switch are arranged particularly far from the switching ring in the device, as is the case with round stylers. Because the second transmission element engages in the eyelet of the first transmission element, the axial displacement of the two transmission elements relative to one another is achieved in a simple manner, without being able to rotate relative to one another.
- the second transmission element is able to hold the first transmission element in the region of the slide switch.
- both the eyelet and the second transmission element have a square cross section.
- the measure characterized in claim 4 makes the assembly of a device equipped with the multiple function switch according to the invention particularly simple.
- the built-in parts can be mounted together with the switches and the transmission elements as a unit in the housing of the device. 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 according to the invention has four switch positions. It is then possible to provide the first switching position for switching off the device, the second switching position for half the blower and heating output, the third switching position for full blower and heating output and the fourth switching position for full blower output and low heating output, so that the rotatability serves to regulate the heating line within the ranges set by the slide switch.
- the fourth switch position has the task of blowing cold air onto the hair with the round styler in order to solidify a shaped curl.
- the round styler shown in the drawing has an essentially cylindrical housing 1 in which an electric motor 2 with an axial blower 3 is arranged. Furthermore, two circuit boards 4, 5 are arranged in the housing 1, which hold the electrical components of the round styler and support body 6 for the electrical heating. A slide switch 8 and a rotary resistor 9 are fastened on the printed circuit board 5. 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. The rotary resistor has the task of controlling the heating output within limits specified by the sliding resistance. 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. For assembly reasons, the switching ring 10 is made of two halves that can be plugged together.
- the switching ring 10 completely surrounds the housing 1 of the round styter. 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 13 in the spherical recesses 14 of 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 10 also has a nose 17 which projects through a housing opening 16 into the interior of the housing 1 and into which a first transmission element 18 projects, which connects the switching ring 10 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. This type of coupling is explained in more detail with reference to FIGS. 3 and 4.
- FIG. 3 shows the switching ring 10 with its nose 17. Furthermore, a switching slide 22 of the slide switch 8 shown in FIG. 1 is shown. The switching carriage 22 and the switching ring 10 are connected to one another by the first transmission element 18. This has the Transmission member 18 has a radially bent portion 23 which engages in the nose 17. The transmission member 18 has at its other end a further radially bent section 24 which engages between two holding arms 25, 26 of the switching carriage 22 which form a clasp.
- the bent section 24 forms an eyelet 27 with a square cross section.
- the second transmission element 20 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 member 20 cannot rotate in the eyelet 27, but in the holes in the holding arms 25, 26.
- An axis of rotation 28 identifies the geometric line about which the actuating part 10 and the two transmission members 18, 20 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 thus actuated. Since the eyelet 27 engages around 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.
- the first transmission element 18 When the switching ring 20 is rotated, the first transmission element 18 also rotates about the axis 28. Since 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 Rotary resistor 9 adjusted so that the heating of the round styler controlled by him is changed in its performance.
