Handheld power tool device

摘要

The invention is based on a handheld power tool device, having at least one safety mechanism, which intervenes in an uncontrolled blocking situation, and which has a sensor unit. It is proposed that the sensor unit is provided for directly detecting at least one orientation parameter of a handheld power tool.

主权项

1. A safety device for use in a handheld power tool having housing, a tool insert fastener for engaging a tool and a drive motor connected to a power supply within the housing and operably coupled to the tool insert fastener for rotating the tool about an axis of rotation extending longitudinally through the tool insert fastener, said device comprising:
at least one safety mechanism configured to disconnect the drive motor from the power supply or to decouple the drive motor from the tool insert fastener to interrupt the rotation of the tool about the axis of rotation in an uncontrolled blocking situation in which the tool seizes in a workpiece causing the housing to rotate about the axis of rotation; a sensor unit associated with the housing and configured to generate data directly indicative of a rotational orientation of the housing relative to the axis of rotation; and a computation unit configured to compare said data generated by said sensor unit at staggered times and to activate the at least one safety mechanism in response to the comparison.
