Electric Hand Held Tool Device

Abstract

The invention relates to an electrical hand tool device, particularly a drill, screwdriver, hammer drill, or percussion drill, with at least an optional rotating drive for a tool mountable in a tool receptor, with a motor housing ( 10 ) and a transmission housing that is separate from the motor housing ( 10 ) but connected with it, whereby the motor housing ( 10 ) is formed of two half-shells ( 12, 14 ) that essentially lie within a plane extending along the longitudinal axis of the electrical hand tool device and dividing the electrical hand tool device essentially into two symmetrical halves ( 12, 14 ) with their side edges matching each other, whereby a handgrip ( 30 ) is provided on the motor housing, and whereby the two half-shells ( 12, 14 ) are connected with each other by means of a clip ( 18 ) extending longitudinally holding them clamped together.

1 .

       2 . Electrical hand tool device as in  claim 1 , characterized in that the clip ( 18 ) completely surrounds the motor housing ( 10 ) in the area of the opposing side edges of the half-shells ( 12 ,  14 ). 
   
   
       3 . Electrical hand tool device as in  claim 1 , characterized in that the handgrip ( 30 ) is formed of two shells, and particularly that each shell ( 31 ,  32 ) of the handgrip ( 30 ) is formed of one piece with a half-shell ( 12 ,  14 ) of the motor housing ( 1 ), and the clip ( 18 ) connects the shells ( 31 ,  32 ) of the handgrip ( 30 ) together. 
   
   
       4 . Electrical hand tool device as in  claim 1 , characterized in that the clip ( 18 ) connects the handgrip ( 30 ) to the motor housing ( 10 ). 
   
   
       5 . Electrical hand tool device as in  claim 1 , characterized in that the handgrip ( 30 ) is positioned at the center of gravity of the electrical hand tool device. 
   
   
       6 . Electrical hand tool device as in  claim 1 , characterized in that the handgrip ( 30 ) is attached to the motor housing ( 10 ) near its connection with the transmission housing. 
   
   
       7 . Electrical hand tool device as in  claim 1 , characterized in that the handgrip ( 30 ) is inclined toward the tool to be inserted. 
   
   
       8 . Electrical hand tool device as in  claim 1 , characterized in that the handgrip ( 30 ) is mounted on the upper side of the electrical hand tool in its operating position. 
   
   
       9 . Electrical hand tool device as in  claim 1 , characterized in that an additional supplemental handgrip may be mounted for two-hand operation. 
   
   
       10 . Electrical hand tool device as in  claim 1 , characterized in that the transmission housing and/or the clip ( 18 ) are made of aluminum. 
   
   
       11 . Electrical hand tool device as in  claim 1 , characterized in that the half-shells ( 12 ,  14 ) of the motor housing ( 10 ) and/or the shells ( 31 ,  32 ) of the grip ( 30 ) are made of plastic. 
   
   
       12 . Electrical hand tool device as in  claim 2 , characterized in that the handgrip ( 30 ) is formed of two shells, and particularly that each shell ( 31 ,  32 ) of the handgrip ( 30 ) is formed of one piece with a half-shell ( 12 ,  14 ) of the motor housing ( 1 ), and the clip ( 18 ) connects the shells ( 31 ,  32 ) of the handgrip ( 30 ) together. 
   
   
       13 . Electrical hand tool device as in  claim 2 , characterized in that the clip ( 18 ) connects the handgrip ( 30 ) to the motor housing ( 10 ). 
   
   
       14 . Electrical hand tool device as in  claim 3 , characterized in that the clip ( 18 ) connects the handgrip ( 30 ) to the motor housing ( 10 ).
