Definitions
- the task of the present invention is therefore to create a suitable, simple and absolutely reliable drive switch-off even with the smallest lifting movement from any housing side.
- Fig. 2 enlarged the limit switch area of the same representation to about 1: 1.
- the known basic structure of the document shredder shown is the cutting unit housing 1, including the lower shell 1b and cutting unit 5, lying on the upper edge 2a of the material collecting container 2.
- a switching element 3 on the housing 1 for the drive shutdown together with switching pin 3a and switching cams 4 on the upper container edge 2a complete this Basic system.
- the device is switched off as soon as the cutting unit housing 1 is moved even a tiny bit out of its basic position; So far, the shortcomings of known devices in terms of safety were mainly that one could lift at least one side of the cutter housing and reach into the interior of the container while the switch cam was still actuating the limit switch.
