Definitions
- the invention is based on a hand tool according to the preamble of claim 1.
- Hand-held power tools in particular hand drills and rotary hammers with housings in pot construction with a closure cover arranged at the end of the cylindrical housing, are known.
- this lid can only be opened with great difficulty with the aid of separate tools, and it is not suitable, or only to a very limited extent, as a service lid for changing the cabbage brushes.
- the known cover cannot be secured against loss on the housing.
- the hand tool according to claim 1 has the advantage that the front housing cover is secured against loss and can be solved without auxiliary tools.
- FIG. 1 shows a spatial representation of a rotary hammer according to the invention with depth stop
- FIG. 2 shows a partial bottom view of the rotary hammer
- FIG. 3 shows an enlarged view according to FIG. 2 shows the view according to FIG. 3 when the cover is opened
- FIG. 5 shows the view according to FIG. 4 with the cover open FIG the casing of the hammer drill and
- Figure 7 shows a partial longitudinal section of the hammer drill
- FIG. 1 shows a spatial representation of a handheld power tool 10 designed as a hammer drill in the view from the front left.
- the handheld power tool has a housing 12, which consists of a left and right longitudinally divided housing shell 121, 122 with a handle 14 designed as a spade handle, which contains a switch button 16, from which an E-cable 18 for energy supply of the not shown, emerges inside a motor housing 20 belonging to the housing 12.
- the motor housing 20 is divided in one piece with the housing shells 121, 122 into motor housing shells 201, 202, which are arranged at right angles to a longitudinal axis 27 of the handheld power tool 10.
- the longitudinal axis 27 is defined by a machine neck 22, a chuck 24 and an insert tool 26 designed as a drill.
- An additional handle 28 also extends downward at right angles from the longitudinal axis 27 and is removably held on the machine neck 22 by means of a tensioning strap 30.
- the additional handle 28 contains an upper extension 29 with a concave, which is intended to bear against the machine neck 22 and gives the additional handle 29 a secure hold on the housing 12.
- the upper extension 29 forms two legs, viewed from the front, of which only the larger supporting leg 31 is specified.
- a depth stop 32 designed as a hexagonal rod is secured against rotation in a longitudinally displaceable manner in a longitudinal guide 38 designed as a hexagonal bore.
- the depth stop 32 has an upper and a lower tooth profile 34, 35 on opposite hexagonal surfaces with which it is releasably retained in the longitudinal guide 38 in a form-fitting manner.
- FIG. 2 shows a section of the lower area of the motor housing 20, this being closed at the end by a hinged cover 60.
- This hinged cover 60 is articulated in the left housing shell 121 in the screw dome 64.
- the hinged cover 60 covers the lower half of the motor housing 20 in the area of the carbon brushes.
- the hinged cover 60 is fastened to the motor housing 20 for operational use by means of a securing screw 66.
- the locking screw 66 is captively connected to the hinged cover 1.
- the connection between the motor housing 20 and the hinged cover 60 is released.
- the hinged lid can be folded away without having to be completely removed from the device.
- the locking screw 66 can be loosened with a screwdriver or with a key or a coin. Folding away the hinged cover 60 enables one simple and convenient carbon brush change.
- the motor housing 20 encompasses a separate envelope housing (FIG. 6) which is inserted between the housing shells 121, 122 during assembly. This casing 62 carries at the lower end a radial outward-pointing threaded bore 68 for the engagement of the locking screw 66 and also the carbon brushes for the motor.
- the right housing shell 122 is designed in two parts. It carries a small cover for inspecting the power line 18. The cover is fastened to the housing 12 with two screws. After removing the cover, the power cord can be easily replaced or replaced.
