Definitions
- the invention relates to an emergency stop button according to the preamble of claim 1.
- an emergency stop device is known, the task of which is to immediately switch off an electrical machine in an emergency.
- This emergency can be, for example, existing danger for the operating personnel, overload or malfunction of the machine.
- switching devices of this type have a rotary mushroom which is mounted at least to a limited extent in a housing and is displaceable in the axial direction of the housing. The switching function is carried out by pushing in the rotary mushroom, the rotary mushroom being locked when it reaches its pressed-in end position, so that retraction of the rotary mushroom, for example in order to restart the machine, is not possible.
- the emergency stop button is unlocked by turning the rotary mushroom relative to the housing. The turning process can be blocked, for example, by a security lock, so that rotation of the rotary mushroom in the housing is only possible after unlocking the security lock.
- An emergency stop button is shown and described in DE-GM 93 06 074, in which two radially arranged pins are pressed apart by a spring. The pins rest on a projection which is provided with a bevel arranged at the top and a bevel arranged at the bottom.
- a clear resistance must be overcome, for example, a certain amount of force must be applied.
- the emergency stop button can be unlocked again simply by pulling up the actuating head in the axial direction, resistance also having to be overcome here.
- DE 44 22 171 A1 shows an emergency stop button that can be unlocked both by rotation and by train.
- the object of the invention is to provide an emergency stop button according to the preamble of claim 1, which can be used both with pull release and with rotary release and is easy to install.
- the object of the invention is achieved by the characterizing features of claim 1, while particularly advantageous developments of the invention are characterized in the subclaims.
