Claims20
A device for supplying a machine tool with electrical energy, the device comprising:
- a rechargeable battery including an interface for connecting the battery to the machine tool and a housing for accommodating at least one energy storage cell, the housing having a top side face, a bottom side face, a first wall side face connecting the top side face and the bottom side face and a second wall side face connecting the top side face and the bottom side face, the first wall side face angled with respect to the bottom side face and connected to the bottom side face at a corner, the interface being at the top side face;
- and
- a shock absorbing device including at least one shock absorber, the shock absorber extending around the corner and having adjoining first, second and third sections with first, second and third inner surfaces, respectively,
- the first inner surface being parallel to and spaced apart from the first side wall face, the third inner surface being parallel to and spaced apart from the bottom side face, and the second inner surface being spaced apart from the corner.
A device for supplying a machine tool with electrical energy, the device comprising:
- a rechargeable battery including an interface for connecting the battery to the machine tool and a housing for accommodating at least one energy storage cell, the housing having a top side face, a bottom side face, a left-hand wall side face connecting the top side face and the bottom side face and a right-hand wall side face connecting the top side face and the bottom side face, the left-hand wall side face angled with respect to the bottom side face and connected to the bottom side face at a corner, the interface being at the top side face;
- and
- a shock absorbing device including at least one shock absorber, the shock absorber extending around the corner and having adjoining first, second and third sections with first, second and third inner surfaces, respectively,
- the first inner surface being spaced apart from the left-hand side wall face, the second inner surface being spaced apart from the corner and the third inner surface being spaced apart from the bottom side face.
