Definitions

  • the invention relates to a hand tool or semi-stationary tool device with Heidelbergerd Wegerbetuschrien, with a housing component, with a switch, which includes a pre-assembled unit a switch base housing with the electrical or electronic components and a switch mounted on the switch housing and guided against the switch base housing switch lever, wherein the switch on the housing component the tool device is arranged.
  • the switch trigger so the operation button of the switch, stored in such aforementioned switches, which form a preassembled structural unit, exclusively relative to the switch base housing and out. If the switch trigger is not depressed exactly in the ideal direction of actuation, so this type of storage and management prepares for a relatively small pusher surface and consequently low tilting moments also no problems.
  • the Applicant has found, however, that such an arrangement, storage and leadership with increasing presser surface of the switch trigger can affect a total disadvantageous. In particular, tilting of the mutually sliding components of the switch trigger and of the switch base housing can lead to damage.
  • US 4,700,031 shows a non-generic tool device in the form of a soldering gun, in which no switch of the type described above is provided with a switch base housing.
  • a switch trigger is arranged as an insulated component between two housing half-shells of the device and guided by a nut and spring-like engagement displaceable and captive.
  • the present invention has for its object to achieve a high ease of use and low susceptibility to interference even with larger sized switch pushers.
  • the switch handle additionally comprises a guide means which cooperates with a further guide means of the housing component to initiate occurring in the handle operation moments in the housing component and a proper movement, in particular a linear guide, the To enable switch presser.
  • the invention proves to be particularly advantageous when the switch pusher has a maximum dimension of the manually-operable pusher surface projected in the actuation direction of at least 2.0 cm, in particular of at least 3.0 cm and more particularly of at least 4.0 cm.
  • a guide supporting the switch handle could be achieved in an advantageous manner by the fact that the guide means of the housing component is formed by a slit-shaped or groove-shaped receptacle.
  • the switch trigger could be supported in its operation both to the sides and up and / or down.
  • the guide means of the switch trigger comprises a transversely extending to the actuation direction tongue-shaped or web-shaped projection which cooperates with a provided in the movement range of the housing component guide means.
  • the guide means of the switch trigger is angled and so causes a positive guidance with respect to two dimensions.
  • the one leg of the guide means can then for example stabilize the movement of the switch trigger to the sides and the other angled leg of the guide means can cause a positive guidance in a plane perpendicular thereto.
  • a plurality of above-mentioned guide means may be provided on the switch lever.
  • the respective guide means of the switch trigger can be made in one piece with this advantageously.
  • the switch trigger can advantageously be a plastic injection molded part.
  • Electric hand tool device 2 in which an electrical switch 6 is provided in the region of a handle 4.
  • the electrical switch 6 represents a pre-assembled unit or assembly 8, which can be purchased as such and installed in tool devices.
  • Such an electrical switch 6 comprises a switch base housing 10, which comprises all electrical or electronic switching components, and a switch trigger 12 (actuating button), which can be pressed by manual pressure on its pusher surface 14 in the actuating direction 16.
  • switch base housing 10 which comprises all electrical or electronic switching components
  • switch trigger 12 actuating button
  • the switch trigger 12 is usually mounted and guided exclusively relative to the switch base housing 10. In the present case, such a guidance function is realized via the central guide pin 18.
  • the switch trigger 12 comprises a largest dimension 20 in a plane perpendicular to the actuation direction 16 projected from about 6 cm. There is therefore the danger that 12 tilting moments are generated when depressing the switch trigger, which could be transmitted in particular via the guide pin 18 on the switch base housing 10.
  • the switch trigger 12 comprises an additional guide means 22 in the form of a protruding from an upper edge 24 tongue-shaped projection 26. This projection 26 merges into a perpendicular thereto angled section 28.
  • the thus formed guide means 22 acts with a matching guide means 30 in the form of a substantially web-shaped wall portion 32 of a housing component 34 of the electric hand tool device 2 together.
  • the web-shaped wall section 32 extends substantially perpendicular to the imaginary plane of a housing half-shell 36, which forms the housing component 34.
  • the assembly of the switch 10 is accordingly carried out in that the switch 10 is inserted quasi perpendicular to the plane of the figure 1 in the relevant housing half-shell 36, whereby the switch trigger 12 reaches the apparent from the figures intended mounting position.
  • the switch trigger 12 rests with the tongue-shaped projection 26 against the end face 38 of the web-shaped wall portion 32 of the housing component 34 and is therefore held in the lateral direction 40. This is supported by that the switch trigger 12 cooperates with an upper edge portion 24 on the opposite side with a lateral end stop 42 of the other housing half shell 44.
  • the switch handle is thus guided on both sides in the direction 40.
  • FIGS. 4 and 5 show an actuated or unactuated position of the switch trigger 12.
  • the reference numeral 50 denotes a device for reversing the direction of rotation.
