Electric tool having a protective hood

Abstract

A piece of equipment which has a ground contact device for working on a ground region located below the ground contact device in the working position of the piece of equipment, a driving device which can be operated by an electric motor in order to produce a working movement of the ground contact device, an electrical energy accumulator, enclosed by a housing, for supplying the electric motor with electrical energy, and a covering device for covering the housing and thus the energy accumulator, which covering device is arranged above the energy accumulator in the working position. The piece of equipment may for example be a tamper, a vibration plate, a roller, or a breaker.

We claim:

         2 . The working device as recited in  claim 1 , further comprising
 a guide device for guiding the working device, wherein   the energy storage device and the covering device are situated on the guide device.   
     
     
         3 . The working device as recited in  claim 1 , further comprising
 an electronic control device for controlling an operation of at least one the drive device and the electric motor, and wherein   the covering device is situated above the control device in the working position thereof, and covers the control device.   
     
     
         4 . The working device as recited in  claim 1 , wherein
 the covering device has an essentially flat covering plate, and wherein the covering plate essentially covers at least one of 1) an upper side, which in the working position is situated at the top on the energy storage device, of the housing of the energy storage device, and 2) an upper side, which in the working position thereof is situated at the top on the control device, of the control device.   
     
     
         5 . The working device as recited in  claim 1 , wherein
 the covering device has at least one of 1) a material that protects against a radiation of heat, and 2) a coating that reflects a significant part of the heat radiation.   
     
     
         6 . The working device as recited in  claim 1 , wherein
 the covering device has a material that protects against the impact of stones.   
     
     
         7 . The working device as recited in  claim 1 , wherein
 the covering device has a pivotable part, and   the energy storage device is removable from a receptacle device in a pivot position of the pivotable part.   
     
     
         8 . The working device as recited in  claim 1 , wherein
 the covering device has a removable part, and   the energy storage device is removable from the receptacle device when the removable part of the covering device has been removed.   
     
     
         9 . The working device as recited in  claim 1 , wherein
 the covering device has a cooling air flow guide for guiding a cooling air flow along at least one of 1) the energy storage device and 2) the control device.   
     
     
         10 . The working device as recited in  claim 1 , wherein
 the covering device has at least one opening for dissipating warm air situated under the covering device.   
     
     
         11 . The working device as recited in  claim 1 , wherein
 the covering device is fastened to at least one of 1) the housing of the energy storage device 2) a housing of the control device.   
     
     
         12 . The working device as recited in  claim 1 , wherein
 the working device has a mass of at least 15 kg, and   the working device is one of
 1) a tamper or a vibrating plate for ground compacting, and wherein the ground contact device has a ground contact plate, 
 2) the working device is a roller, and wherein and the ground contact device has a roller lining, and 
 3) a breaker, and wherein the ground contact device has an impact device. 
   
     
     
         13 . A working device, comprising:
 a ground contact device that processes a ground region that is situated underneath the ground contact device when the ground contact device is in a working position thereof;   an electric motor;   a drive device that is operated by the electric motor to produce a working movement of the ground contact device;   an electrical energy storage device that supplies the electric motor with electrical energy;   a housing in which the electrical energy storage device is enclosed; and   a covering device that is situated in a position that is above the energy storage device when the ground contact device is in the working position thereof and that covers the housing and the energy storage device.
