Definitions

  • the invention relates to an electric tool with at least one control element for starting it up and with a coding device according to the preamble of the main claim.
  • a coding device is provided in the connecting cable which, when plugged into the power supply device, transmits typical data of the power tool to the control of the power supply device.
  • the controller is then able to specify the signals to be delivered to the power tool.
  • the unauthorized commissioning of the power tool is not influenced by the coding device, however, so that any unauthorized user can also use the power tool. Since power tools can sometimes have very dangerous cutting tools, unauthorized use by everyone is not always desirable. Another problem arises from theft of Power tools, especially on construction sites, so that considerable damage is caused.
  • the power tool according to the invention with the characterizing features of the main claim has the advantage that the commissioning of the power tool is only possible if the correct code is entered. This signals to an unauthorized person that he cannot use the tool if he does not know the correct code. The legal owner or user of the power tool, however, can use the tool without restriction, so that it is not hindered by the coding device.
  • a mechanical lock for example the drill chuck of a drill or the drive shaft, can also prevent an unauthorized person from starting up the power tool if the blocking device is attached to the drill chuck or the drive shaft in a clearly recognizable manner.
  • a coding device in the form of a code card can be provided, as is known as a telephone card or check card.
  • the code card advantageously contains a code that can be read with simple electromagnetic or optical readers.
  • the code card can also be electrically wired or have a mechanical lock that can also be decoded by the power tool. Since the code cards are flat and handy, they can easily be kept by a legal user of the power tool and can be inserted into the power tool if necessary. This ensures simple securing of the power tool.
  • a switch lock can also be used, for example by blocking the main switch of the power tool. This switch lock can be unlocked with a simple key.
  • the use of a keypad with which a release code can be entered is particularly advantageous.
  • the keypad is firmly connected to the power tool, so that no additional individual parts are required for coding.
  • the code device blocks the release for use again after a predetermined rest period of the power tool. If the power tool is left unused for a long time, for example on a construction site, the power tool locks up automatically. If the power tool is stolen, it can no longer be used without entering a code.
  • FIG. 1 four different exemplary embodiments are shown, in Figure 2 a fifth exemplary embodiment is shown and Figure 3 shows schematically the coupling of the coding device with a switch in the circuit of the power tool.
  • FIG. 1 schematically shows a hand drill 1 designed as a power tool, in which a known speed controller 4 is arranged in the pistol grip.
  • a locking lock 6 is attached to the speed controller 4 in the pistol grip of the drilling machine 1, which lock prevents the speed controller 4 from being actuated in the closed state.
  • the lock for example, is operated with a key. To unlock the key is inserted into the lock 6 and thus the pressure path of the speed controller 4 released.
  • the coding device is carried out instead of the locking lock 6 in conjunction with a direction of rotation switch 5 which is arranged above the speed controller 4.
  • the changeover switch 5 reverses the direction of rotation of the electric motor.
  • the changeover switch is designed so that its operating lever is designed to be removable. By pulling the power supply to the electric motor is cut off. The power tool can then no longer be put into operation.
  • a device is provided on the pistol grip of the drilling machine 1 which is designed to receive a code card 7.
  • code card 7 Known magnetic cards or optically readable cards, for example encoded with a bar code, can be used as code card 7.
  • the reading device is also connected to the power supply to the electric motor connected and blocks the flow of current when the code card is removed or an incorrect code card is inserted.
  • an electrically wired card can also be used. This card has several contact areas that are wired according to a specific code. By inserting this electrical card, corresponding contacts in the reading device are closed.
  • the advantage of the electrical card is that it is less sensitive to electromagnetic interference or contamination. It can therefore be used advantageously on construction sites with dirt and dust.
  • Mechanically structured cards with holes or cutouts can also be used. Contact pins can be passed through the holes or recesses, via which the circuit for the motor can be controlled.
  • blocking of, for example, a chuck 2 of the drilling machine 1 can be provided.
  • a blocking device 8 is inserted into the chuck, which blocks the opening or closing of the chuck jaws.
  • This blocking device 8 can, for example, be coupled to a key which blocks the chuck 2 by locking its lock. In the closed state, the locking device cannot be removed, so that the power tool cannot be used.
  • it is provided to block the output shaft of the power tool with a corresponding device instead of the drill chuck.
  • a fifth embodiment of the invention is shown in Figure 2.
  • a keypad 9 is arranged, for example with four buttons.
  • the keypad is connected to the power supply of the Power tool 1 connected and releases them only when a certain key sequence has been entered.
  • FIG. 3 shows a block diagram of the circuit diagram with a coding device.
  • the current flows from the mains or a battery via a switch 12 and the speed controller 4 to the controller 11.
  • the controller 11 is connected on the output side to the electric motor of the power tool 1.
  • the additional switch 12 is released via the coding device 10.
  • the coding device 10 can be controlled via the lock 6, the code card 7 or the keypad 9. It can also be designed to accommodate the diverter 5, which prevents the switch 12 from closing when it is removed.
  • the code device 10 advantageously includes a timer which closes the switch 12 for a predetermined period of time, a few minutes or hours after the last use. After this period, the switch 12 is automatically opened so that the power supply to the power tool is interrupted. The correct code must be re-entered into the coding device in order to be put back into operation.
