Definitions

  • the present invention relates to a power tool with controls for Adjusting operating parameters of the power tool, each of the Controls is responsible for the setting of another operating parameter.
  • Such a power tool with an on / off switch and as a Pressure sensor formed additional operating element is formed, is from the DE 197 38 092 C1 known. These two different controls are on various locations on the handle of a power tool arranged.
  • By means of as Pressure sensor formed operating element the speed of a drive motor be set, and by means of designed as an on / off control element the power supply to the drive motor can be switched on or off. Because the Controls are located in different places, need for adjustment From operating parameters different handles are made, which is under Circumstances, the operation of the power tool difficult.
  • the invention is therefore based on the object, a power tool of the above specify the type mentioned, the most user-friendly setting of Operating parameters has.
  • the responsive depending on the operating pressure control element has preferably a pressure sensor.
  • the at least one first operating element and the at least one second operating element directly above one another, with the intermediate support of the movable support, are stacked.
  • the movable support as a Lever is fixed on one side and that between this movable support and the fixed support lying second control closer to the fixation point of the movable Pad is arranged as that between the flexible cover and the movable Overlay first operating element. Due to the leverage of the movable support can the operating force on the lying under the movable support Considerably reduce the operating element.
  • a microcontroller is present, the output signals of the Controls in control signals for one or more operating parameters converts. Likewise, the microcontroller can time the order in which the same time operated controls are to be effective control.
  • One of the controls adjustable operating parameters can, for. B. the speed and / or the torque of a drive motor.
  • FIG. 1 shows a schematic representation of a combination of several Operating elements for setting operating parameters of a power tool. Adjustable operating parameters are z. B. a switched on and off work function of Power tool or the variable speed or the variable torque a drive motor of a power tool.
  • the arrangement shown in a cross-sectional view consists of two in Actuation direction (arrow) stacked controls and one first operating element 1, in response to an operating pressure exerted on it a change of one or more operating parameters of the power tool causes and a second operating element 2, which is designed as an on / off switch.
  • That up Pressure-responsive control element 1 has a pressure sensor, for. B. one piezoelectric transducer or a pressure-dependent resistor (force sensing resistor).
  • Such, known per se pressure sensor has the property that to be Output signal, z. B. its output voltage, with increasing exerted on him Pressure rises.
  • the designed as an on / off control element 2 can be a common Be push button.
  • the executed as an on / off control element 2 can be used to z. B. to turn on or off the power for a drive motor of a power tool.
  • the other, pressure-sensitive control element 1 is suitable to z. B. the speed or the torque of the drive motor on the operating pressure on the operating element. 1 to set to a desired value.
  • Controls 1 and 2 creates a frictional coupling between the two Operating elements 1 and 2, so that at an actuating pressure in the arrow direction on the top control 1 and the underlying other control 2 operated becomes.
  • a flexible Cover 3 At the top, which is accessible to the operator, is a flexible Cover 3 on the housing of the power tool.
  • the first operating element 1 in this case a pressure-sensitive operating element, arranged.
  • a movably mounted support 4 Between the control element 1 and the arranged underneath Operating element 2 is a movably mounted support 4 inserted.
  • the lower Control element 2 finally lies on a relative to the housing of the power tool fixed edition 5 on. Now in the direction of the arrow, a pressure on the flexible cover.
  • this control element 1 gives the Actuation pressure on the movable support 4 to the underlying Control element 2 on.
  • both controls are 1 and 2 activated at the same time. So can by an operating pressure on the flexible Cover 3 z.
  • both the drive motor turned on and its speed a desired value can be set.
  • FIG. 2 differs from that in FIG The figure 1 shown only in that the two controls 1 and 2 in their Arrangement are reversed.
  • the two controls. 1 and 2 are stacked directly above one another, the controls are 1 and 2 in the embodiment of Figure 3 perpendicular to the actuation direction (arrow) arranged offset from one another.
  • the movable Pad 4 between the controls 1 and 2 designed as a lever by this movable support 4 is fixed on one side on the housing of the power tool.
  • One of the both controls 1 and 2, here the running as an on / off control 2 is arranged closer to the fixing point 6 of the movable support 4 than the other Operating element 1. The operating pressure is shifted from the operator to the remoter Operating element 1 exercised, and this operating pressure is on the lever of the support 4 transferred to the other control element 2.
  • a corresponding control When at the same time operable with each other by an actuating pressure coupled controls the controls in time staggered effect should be provided, a corresponding control must be provided.
  • Control 4 shows an embodiment in the form of a block diagram.
  • These Control consists essentially of a computing unit, preferably one Microcontroller 8. Here are at two control inputs 81 and 82 of the microcontroller. 8 the two controls 1 and 2 connected.
  • the control element 1, here with the Symbol of a potentiometer is a pressure-sensitive control element, and the operating element 2, shown here with the symbol of a switch, is as an on / off switch trained operating element.
  • the dashed double line between the both controls 1 and 2 indicates the above-described non-positive coupling between the two controls 1 and 2 on. Both controls 1 and 2 are located to a supply voltage U on.
  • the drive circuit 9 may consist of a or multiple interconnected power transistors.
  • the microcontroller 8 controls the drive circuit 9 initially so that the Circuit is closed by the drive motor 10. Only then does the Microcontroller 8, the drive circuit 9 so that the speed or torque the drive motor depending on the force exerted on the control element 1 Pressure changed.
