Definitions

  • the application relates to a device for adjusting the pitch of a timpani by tensioning the eardrum, the edge of which is connected to a vertically adjustable disc.
  • Such a device is generally known because the commercially available kettle drums are provided with such devices.
  • the disc In the known kettledrum, the disc is connected to a pedal by means of a lever transmission. The pitch is adjusted by pressing the pedal. Since adjusting the pitch with these known means requires considerable effort, playing the kettle drums also requires good physical condition.
  • the invention is therefore based on the object of providing a device for adjusting the pitch of a kettle drums, in which the physical efforts previously required are no longer necessary and with which an adjustment can also be carried out very quickly. Further advantageous properties are the precise, infinitely variable setting option and the invariability of a value that has been set once.
  • the kettledrum initially has the kettle 1.
  • the upper, open end of the kettle 1 is covered with the taut eardrum 2, which can be kept taut in a ring 3, for example.
  • the ring 3 in turn is coupled to the washer 5 via the tensioning screws 4.
  • the disk 5 is coupled to the pull rod 6, which is to be adjusted vertically. This is achieved in that the rotational movement of the output shaft of the stepping motor 7 is transmitted to the pull rod 6. Stepper motor 7 and disc 5 with pull rod 6 are mounted on the base frame 8.
  • FIG. 3 Details of the arrangement with which the rotational movement of the stepping motor 7 is converted into the linear movement of the pull rod 6 is illustrated in FIG. 3.
  • the pull rod 6 is provided with the opening 9 at its lower end.
  • the abutment 10 and the threaded output shaft 11 project into this opening 9.
  • the wedge 12 is fastened to the bottom of the opening 9 and the output shaft 11 plunges into the second horizontally adjustable wedge 13. If the output shaft 11 of the stepping motor is now set in rotation, then the wedge 13 is moved to the left or right, as a result of which the pull rod 6 is moved downwards or upwards.
  • FIG. 4 Another embodiment of the device with which the rotational movement of the stepping motor 7 is transmitted to the disk 5 is illustrated in FIG. 4.
  • the disk 5, which is secured against rotation, is provided in the center with a threaded nut.
  • the stepping motor 7 is turned on, the rotation of the output shaft 11 is directly converted into an upward or downward movement of the disk 5.
  • the proposed solution not only allows the pitch to be adjusted quickly and easily with a kettle drums, but also opens up greater ease of use.
  • the simplest way of adjustment is that the stepper motor is operated by means of a foot switch 15 in one or the other direction of rotation until the desired pitch setting is reached. If necessary, the adjustment can also take place at different speeds, ie the larger part of the adjustment range is bridged quickly and the final adjustment is carried out more slowly.
  • the pitch can be displayed mechanically in a known manner.
  • the stepper motor can also be provided with an electronic control, which is able to store the desired pitch levels at the push of a button.
  • the desired pitch level can be called up by actuating a foot switch, with one pitch step being advanced, for example, each time the switch is actuated. It is also conceivable that the setting of a stored pitch level is triggered directly by pressing a key. It also opens up the possibility of preselecting and storing the pitch levels according to the piece of music to be played. Switching to the next required pitch level can either take place automatically depending on the time or by pressing a foot switch.
  • the set pitch level can also be displayed on a clearly readable panel 16 by means of indicator lamps or the like.
  • the adjusting device described above also allows the kettle drums to be easily tuned before and, if necessary, during a concert.
