Definitions

  • the invention relates to an electrical hair care device with a switch arrangement for operating the hair care device, comprising an electric Push button and one movable against the push of the button the force of a spring element can be actuated and in its actuation position lockable control button.
  • Electric hair care devices such as hair dryers, curlers or the like can also push buttons in addition to slide or rocker switches have as additional switches.
  • Such buttons are usually through switch arrangements realized that on the one hand this electric button, too formed as a microswitch and include a control button that slidable in the housing of the hand-held device for pressing the button is stored.
  • microswitches that often the Installation tolerances of the switch arrangement in the housing of such electrical handset are not insignificantly larger than the switching stroke a microswitch, which can be, for example, only 0.5 mm. Therefore is an installation of the control button to the microswitch of a higher one Assembly accuracy subject to assembly of the remaining components of such an electrical handheld device. This is undesirable because such an assembly can only be realized with considerable additional effort would.
  • microswitches are used because they have only a relatively small installation space is available.
  • For handling the control button one such electrical hand-held device, however, it is desirable that the movement stroke the control button is larger than the switching stroke of the microswitch, to make a conscious actuation movement by a user to request the actuation of the microswitch and the possibility to reduce unwanted button operations.
  • a similar configuration of a switch arrangement is from US 4,879 438 A1 known.
  • This document serves as a control button a lever articulated like a rocker arm, with its back a button can be operated. At the free end of this control lever is pivoted a locking hook with which the operating lever can be locked in its position actuating the button. In this Position the hook engages behind a pin. To achieve the locked The position of the operating lever is in the operating direction of the operating lever the locking hook can be opened.
  • a disadvantage of these two known designs of an operating button lock is that a lock in the actuated control button position by approximately the same movement as the actual one The button is activated. There is therefore a risk that the control button in its locked position is brought without this actually being desired is. In the case of hair care devices, for example, this can result in a lead to long-term exposure to heat.
  • the invention lies on the basis of this prior art discussed therefore based on the task of a generic electric hair care device to develop such that an unconscious Locking the control button is avoided.
  • the switch arrangement a movably mounted and operated by the control button Includes actuator, at least in the locked position of the control button for pressing the button between the control button and the button is arranged, the actuator by actuation of the control button in a direction transverse to the direction of actuation the direction of the push button movable in its locked position is.
  • the hair care device comprises a by the control button Actuatable actuator for moving the button in the locked Position of the control button.
  • This measure allows a Movement of the control button can be exercised, for example a sliding movement to move the control knob into a locked position bring. At least in the locked position of the control button The button is then actuated indirectly by the control element via the actuator.
  • the combined arrangement with the spring element in the switch arrangement also leads to a tolerance compensation with regard to the intended Possibility of locking the control button.
  • There to move the actuator into the locked position of the control button the control button in a direction transverse to the actual actuation direction of the button Direction must be operated, a control button lock only consciously, namely by exercising this movement.
  • the control button locked there is no risk with the claimed hair care device that unintentionally when a short push button operation is desired, the control button locked.
  • the actuator forms a concrete unit with the control knob, with between the actuator and the control button the spring element for exercising a pressure directed against both elements is arranged.
  • the actuator can be operated using the control button opposite side on the surface of the push button housing support and expediently designed as a sliding shoe be on the button housing surface together with the control button is movable.
  • the control button is in the locked position the slide shoe on the button and holds it in its actuated Position.
  • the push button Position can be provided that this on his to the button facing edge is chamfered and / or and that first a button operation done by the control button itself before the shoe is pushed over the actuated button.
  • an actuator is pivotable articulated lever, advantageously a one-armed lever is provided, on which the control button acts and which in turn actuates the button is provided.
  • a one-armed lever is provided, on which the control button acts and which in turn actuates the button is provided.
  • a locking of this control button can, for example brought about by an additional locking button the control button in its engaged position leaves.
  • a hair dryer 1 as an electrical hair care device comprises a slide switch 2 for switching on the hair dryer 1 in different Power states.
  • the slide switch 2 includes the hair dryer 1 shows a switch arrangement designated overall by reference number 3, which is designed as a so-called boost button, based on the power set with the slide switch 2 Hair dryer 1 increase this by a certain amount.
  • the switch arrangement 3 is shown enlarged in FIG. part of Switch arrangement 3 is a control button 4, which is in the housing 5 of the Hair dryer 1 is slidably mounted in the horizontal direction, such as this is indicated by the arrow shown in this figure is.
  • the button 7 of the microswitch 6 can be compared to the housing 8 of the microswitch 6 also according to the direction of the arrow assigned to the control button actuate.
  • the control button 4 is supported by a compression spring 9 as an actuator serving slide shoe 10, which in turn on the control button 4 facing side of the housing 8 of the microswitch 6 and can be moved on this page.
  • Figure 2 shows the switch arrangement 3 in their unswitched position.
  • the control button 4 is in this position through which on the slide shoe 10 on the surface of the housing 8th of the microswitch 8 supporting compression spring.
  • the end position the control button 4 is through corresponding projections of the housing 5 of the hair dryer 1 determines where the control button 4 in this Position is present.
  • the control button is in this switched position 4 can be displaced in the vertical direction together with the sliding shoe 10, so that the initially adjacent to the top of the housing 8 Surface of the slide shoe 10 now pushed over the button 7 and keeps it in its switched position.
  • the force of the compression spring 9 is sufficient so that the control button 4 frictionally on the inside the projections of the housing 5 is fixed, so that by this Measure the control button 4 is locked in its switched position.
  • the control button 4 can also directly be brought into its locked position, so that this then is effectively used as a slide switch.
  • a further switch arrangement 13 which is also for a hair dryer is provided to provide a boost effect.
  • the switch arrangement 13 in turn comprises a microswitch 14, the Key is labeled with the reference number 15.
  • a control button 17 which is in the housing 16 can be pressed in according to the arrows shown.
  • the control button 17 has two individual arms 18, 19, the arm 18 acts as a plunger for actuating a one-armed lever 20.
  • the lever 20 is pivotally held in the housing 16 by a cam 21 and serves to actuate the button 15 of the microswitch 14.
  • the lever 20 is against the force of a compression spring 22 by the control button 17 Pressing the button 15 movable.
  • the lower end is at rest of the arm 18 on the top of the actuation extension 23 of the lever 20.
  • Compression spring 22 responsible for the control button 15 in its Basic position remains.
  • the two arms 18, 19 of the control button 15 are part of a displaceable Locking button 24, which, as shown by the further arrow, is displaceable with respect to the control button 17.
  • the bottom end of the arm 19 carries a locking cam 25, which is shown in FIG unswitched zero position of the switch arrangement 13 in a Opening of the housing 16 is arranged.
  • the locking cam 25 is then located behind a web of the housing 16, so that a provision in this position of the control button 17 by the spring force of the compression spring 22 is prevented. Consequently, the control button 17 is locked while the button 15 of the microswitch 14 is actuated.
  • FIG. 5 shows this switch arrangement with the operating button 17 actuated, but not in its locked position.
