Abstract
The invention relates to a tool apparatus (10) with a drivable tool (1), comprising a shaft (2) which is coupled to the tool (1), further comprising one or plural braking bodies (3) which in particular are arranged distributed around the shaft (2) in the circumferential direction, wherein the tool apparatus (10) is adapted to bring the one or plural braking bodies (3) from a release state into a braking state in the course of a braking procedure, wherein in the braking state the one or the plural braking bodies (3) are in contact with the shaft and thereby exert a braking force upon the shaft (2), so that the shaft (2) and thereby also the tool (1) are braked and wherein in the release state the one or the plural braking bodies (3) are not in contact with the shaft (2).
Claims15
A tool apparatus with a drivable tool, the tool apparatus comprising a shaft which is coupled to the tool, the tool apparatus further comprising:
- at least one braking body,
- wherein the tool apparatus is adapted to bring, in the course of a braking procedure, the at least one braking body from a release state into a braking state,
- wherein, in the braking state, the at least one braking body is in contact with the shaft and thereby exerts a braking force upon the shaft, so that the shaft and thereby also the tool are braked and
- wherein in the release state the at least one braking body is not in contact with the shaft,
- wherein the tool apparatus is adapted to bring, in the course of the braking procedure, the one or more braking bodies from the release state into a carry-along state and from the carry-along state into the braking state, wherein, in the carry-along state, the one or more braking bodies are carried along by a movement of the shaft, so that the bringing of the one or more braking bodies into the braking state is assisted by way of the movement of the shaft.
A tool apparatus with a drivable tool, the tool apparatus comprising a shaft which is coupled to the tool, the tool apparatus further comprising:
- at least one braking body,
- wherein the tool apparatus is adapted to bring, in the course of a braking procedure, the at least one braking body from a release state into a braking state,
- wherein, in the braking state, the at least one braking body is in contact with the shaft and thereby exerts a braking force upon the shaft, so that the shaft and thereby also the tool are braked and
- wherein in the release state the at least one braking body is not in contact with the shaft,
- wherein the tool apparatus is adapted in a manner such that the at least one braking body can be brought from the braking state back into the release state by way of a manual actuation.
