Definitions

  • the present invention relates to a hand tool with a button for turning on and off an electric motor.
  • the hand tool of the invention has a tool holder for holding a tool, an electric motor for driving the tool holder and a handle for holding and guiding the power tool.
  • a push button has a push button housing, a pin which can be displaced on an actuation axis, and an electric slider connected to the pin, which is displaceable on an electrical slider track along the actuation axis.
  • the probe housing is pivotally suspended in the handle about a pivot axis perpendicular to the actuating axis.
  • the pen closes dust-tight with the button housing to prevent dust from entering the button housing.
  • the dustproof finish is mechanically resistant to stress.
  • the probe housing can advantageously align pivoting, so that no lateral forces acting on the pin and the burden of dust-tight closure can be reduced.
  • One embodiment provides a stylus cap, which is attached to the handle with a hinge, wherein a rotation axis of the rotary joint is parallel and offset from the actuation axis.
  • Fig.1 1 shows a drill 1 as an example of a hand tool.
  • the drill 1 has a tool holder 2 in order to support a tool 3 like a drill, a screwdriver, etc..
  • An electric motor 4 is coupled via a drive train 5 with the tool holder 2 in order to drive this.
  • the user can switch the electric motor 4 on and off via a button 6 .
  • the button 6 is arranged on a handle 7 , which serves the user for holding and guiding the drill 1 during its operation.
  • a power supply of the electric motor 4 can be done by a mains-powered power source or attached to a machine housing 8 of the drill 1 battery pack 9 .
  • the button 6 has a probe housing 10th Within the probe housing 10 is a movable electric grinder 11 , the two contacted depending on its position, two electrical slider tracks 12 with each other.
  • the electric grinder 11 can, for example, contact only one of the slider tracks 12 in a basic position; in a depressed position of the button 6 , the slider 11 connects the slider tracks 12 .
  • the slider tracks are, for example, connected in a current path 13 or signal path.
  • the electric motor 4 is supplied with power when the slider tracks 12 are connected to each other.
  • a motor controller senses an electrical connection of the slider tracks 12 and responsively drives the electric motor 4 .
  • the slider tracks 12 may be formed as resistor tracks.
  • the structure with the two slider tracks 12 is illustrative, other embodiments may have only one or more than two slider tracks 12 , which are contacted by the one slider 11 or more wiper.
  • a pin 14 protrudes partially from the probe housing 10 .
  • the pin 14 is arranged on the actuating axis 15 and guided on coaxial with this movable.
  • the actuating axis 15 is preferably parallel to the slider tracks 12 .
  • the probe housing 10 has a coaxial with the actuating axis 15 sleeve 16 , in the the pin 14 slides along the actuating axis 15 .
  • the pin 14 can be pushed from a basic position in the probe housing 10 along the actuating axis 15 .
  • the pin 14 is preferably biased by a spring 17 in the basic position.
  • the wiper 11 is arranged on the pin 14 and can thus be actuated from outside the probe housing 10 by means of the pin 14 .
  • a sealing element 18 covers the pin 14 in order to reduce or prevent dust entry into the probe housing 10 .
  • the sealing element 18 can be arranged as shown on the outside of the probe housing 10 or on the inside of the probe housing 10 . Alternatively, the sealing element can also be arranged within the sleeve 16 for the guidance of the pin 14 .
  • the sealing element 18 has a central opening through which the pin 14 is guided. A cross section of the opening has approximately the same diameter as the pin 14b .
  • the sealing element 18 may be an O-ring or a bellows.
  • the button 6 is suspended in the handle 7 about a pivot axis 19 pivotally.
  • the exemplary probe housing 10 has two opposed cylindrical studs 20 .
  • the knobs 20 lie in corresponding recesses 21 of the handle 7 .
  • the defined by the knobs 20 pivot axis 19 is perpendicular to the actuating axis 15th
  • the pivot axis 19 and the actuating axis 15 lie in one plane, ie the pivot axis 19 intersects the actuating axis 15th
  • the pin 14 of the probe 6 protrudes from the handle 7 , ie the actuating axis 15 is perpendicular or substantially perpendicular to the handle axis 22 of the handle 7th
  • one or more stops 23 are preferably provided, which limit the pivot angle of the probe 6 .
  • the maximum pivot angle of the probe 6 about the pivot axis 19 is between 0.5 degrees and 5 degrees.
  • a stylus cap 24 covers the pin 14 .
  • the stylus cap 24 may be attached to the handle 7 with a pivot 25 .
  • the hinge 25 is along the handle axis 22 to the pin 14 , ie the actuating shaft 15 , offset.
  • the stylus cap 24 abuts against the pin 14 .
  • the user grasps the handle 7 and the button cap 24 with one hand and pivots the button cap 24 in the direction of the handle 7 by closing the hand, whereby the pin 14 is pushed into the probe housing 10 .
  • the stylus cap 24 may be connected by a pin 26 with the pin 14 .
  • the pin 26 is preferably parallel to the pivot axis 19 .
  • An alternative button cap 27 is rigidly mounted on the pin 14 .
  • the push-button cap 27 moves parallel to the actuating axis 15 .
  • the drill 1 is an example to illustrate the button 6 , other power tools are electric screwdriver, circular saw, jigsaw, angle grinder, electric chisel, etc ..
