Definitions

  • the invention is based on a hand machine tool the preamble of claim 1. It is such a hand machine tool known from DE 195 38 252 A1.
  • the shell element has engagement projections on its outer edge on, which in corresponding receiving grooves in Intervene in the handle.
  • the shell element is either screwed or clamped with the handle. In each Fall is between the shell element and handle a backlash-free Connection provided. Operation of the hand machine tool without a shell element is not permitted, because only that Shell element the handle against the ingress of dirt or water protects. When operating the hand tool Vibrations that occur cannot be effectively damped become.
  • the invention is based on the object effective shock absorption with easy handling of the hand tool ensure, the hand tool also at removed shell element fully functional is. This task is characterized by the characteristics of the characterizing part of claim 1 solved.
  • FIG. 1 shows a section through the handle part a hand power tool
  • Figure 2 is a view of the handle part with the damping device removed
  • FIG. 4 shows a view of the handle part according to FIG. 3 in Contact position.
  • 10 denotes a hand tool, of which a rear part is shown.
  • the hand machine tool 10 has a machine housing 11 which i.a. one Drive motor 12 takes.
  • To the machine housing 11, which is composed in a known manner from two housing shells is also a two-shell composite Handle 13 molded.
  • a Switch 14 by means of which the drive motor 12 via a Push button 15 is controllable.
  • the handle 13 has a known, pistol grip-like shape that allows the user to apply a pressing force in the direction of a tool progress enables. In the example shown, it is in the hand-held power tool 10 by an impact drill or a hammer drill, in which the tool progress in the longitudinal direction of the drilling tool and therefore a pressing force is to be applied in the direction of an arrow 21.
  • the housing wall serves as the pressure surface for the operator on the rear part 24 of the handle 13.
  • This Part 24 of the handle 13 is of a shell element 25 covered, which consists of a hard base body 26, which has a soft coating 27 in the area of the pressing surface wearing.
  • the shell element 25 is in fastening points 30, 31 with connected to the machine housing 11 or to the handle 13.
  • a first attachment point 30 is in the area of the free End 18 of the handle 13 is provided.
  • the from a resilient tongue 32 formed on the base body 26 is formed, on which a locking hook 33 is formed.
  • the Locking hook 33 engages behind in the mounting position of the shell element 25 a projection 34 on the handle housing 13.
  • a second attachment point 31 is on the machine side End of the handle 13 in the area of its approach to the machine housing 11 provided.
  • the tab 36 engages behind a paragraph 38 on the machine housing 11, the serves as a stop for the tab 36.
  • the special type of attachment of the shell element 25 ensures in the first attachment point 30 almost backlash-free connection of shell element 25 and handle 13 in the pressing direction (arrow 21).
  • the receiving opening 37 is significantly wider than the tab 36 so that in the pressing direction (arrow 21) there is a clear play of movement.
  • the shell element 25 around its first attachment point 30 pivotable within limits, so that the tab 36 when pressed in Direction of arrow 21 against one opposite paragraph 38 Stop on the machine housing 11 are pressed can.
  • the shell element 25 is removed from the handle 13 shown.
  • the handle 13 is also without a shell element 25 fully functional and in hand machine tools in the usual way composed of two housing shells, that roughly in a longitudinal plane of the hand tool 1 are divided.
  • the handheld power tool 10 such as conventional machines without special damping Handle is common, possible.
  • the handle 13 is to be equipped with effective damping the damping element 40 is in the recess 43 used.
  • the two housing shells to separate the machine housing 11 and the damping element 40 in between.
  • the damping element 40 is over an edge 40a in a form-fitting manner in the handle 13 or in the machine housing 11 held.
  • the tab 36 is first in the receiving opening 37th introduced, then the shell member 25 with his the first attachment point 30 facing end the handle 13 pressed, the tongue 32 on the projection 34 resiliently withdraws until the locking hook 33 behind the projection 34 can snap into place.
  • the shell element 25 is then attached to the handheld power tool 10 without tools and then takes in the direction of the arrow without exerting a pressing force 48 the rest position shown in Figure 3. Between the hidden ones and therefore dashed housing contours 11a, 25a of the machine housing 11 and the shell element 25 then in the area of the second fastening point 31 Game s.
  • the damping element 40 is thus between the machine housing 11 and shell element 25 interposed, that it is the shell element 25 under tension from the handle 13 away in the direction of the stop 38 on the machine housing 11 urges, which limits the game to a maximum value s becomes.
  • the shell element 25 is, for example, by Opening the two-shell machine housing 11 possible because then the locking hook 33 can be moved laterally past the projection 34 is. But it would also be conceivable in the handle housing provide an opening through which the tongue 32 pushed back in the sense of an unlatching on the projection 34 can be.
  • the hand tool 10 is in the working position shown in which on the shell member 25 by the operator Pressing force 48 is applied.
  • the damping element 40 is elastically deformed by a maximum of the game s.
  • the Shell element 25 then comes at least with its tab 36 for contact with the machine housing 11.
