Definitions
- the invention relates to a hand-held power tool according to the preamble of claim 1.
- the rear area of the handle is formed by a half-shell, which is screwed onto the other (front) part of the handle.
- a shell part made of a soft elastic plastic, which is provided with recesses for receiving the pins.
- the shell part is centered on the handle half-shell by means of a transverse groove and spring connection
- thin projections are provided on both sides of the half shell, which engage behind undercut longitudinal lips of the shell part made of soft plastic.
- the invention has for its object to provide a shell part which has comparatively better damping properties, can be securely fixed and is easy to assemble.
- the support frame 14 made of a hard plastic and matched to the outer contour of the recess 10 in the rear region of the handle 11 of the power tool 13 has in pairs three tab-shaped projections 15, 16 and 17, which are provided with locking lugs 15 ', 16' and 17 'are provided.
- the support frame 14 contains three centering cams 18, 19 and 20, to which centering recesses 22, 23 located on the underside of the upper collar 21 of the handle 11 consisting of two halves are assigned. (See Fig. 3 and 6).
- the two handle halves forming shell halves 11 'and 11 ⁇ as shown in FIG. 3, in the embodiment each have three openings 24, 25 and 26, each of which is undercut, so that the detents 15', 16 'and 17' of Support frame 14 when placing the shell part 28 illustrated in FIG. 2, combined with the contour part 27 made of a soft plastic, engages behind the undercuts 29 on the handle (see FIG. 5).
- knob-shaped elevations 31 on the inside of the contour part 27 made of soft plastic, which have an additional damping effect.
- the inventive design of the shell part 28 made of different hard plastics ensures that the number of springs of the part of the soft plastic located in the space between the supporting structure 14 can be varied better and the damping property of the shell part 28 can be optimized.
