Abstract: It is proposed that a divot tool comprising a handle part and a fork part be constructed as a divot tuning fork whereby the fork part is in the form of a tuning fork which vibrates at a defined frequency, and in that the construction of the handle part and the arrangement of the fork part on a handle part be such that the handle part does not substantially affect the frequency of vibration of the fork part.

Abstract: In order to improve a chin rest for a musical instrument having a chin support and a holding device for holding the chin support on the musical instrument, with the holding device comprising at least one clamping element which is adjustable for clamping the chin support to the musical instrument in a clamping direction, such that it is easy and safe to use, it is proposed that the chin support be provided with an insertion guide for the at least one clamping element, and that the insertion guide be arranged and designed such that the inserting direction is at an incline to the clamping direction.

Abstract: A metronome mechanism comprises a bearing frame with a web and two limbs protruding from the web, a winding stem carrying a spring housing, a ratchet wheel stem carrying a ratchet wheel and bearing bushes arranged on the limbs of the bearing frame for receiving the ends of winding and ratchet wheel stems. The bearing bushes are formed on two separate side parts which are adapted to be pushed onto the limbs of the U-shaped bearing frame and firmly locked on the limbs.

Abstract: In a metronome, a toothed wheel and a bell drum each comprise toothings facing each other, by means of which the toothed wheel and the bell drum are in positive engagement with each other in defined angular positions. The toothed wheel and the bell drum are axially displaceable relative to each other on the toothed wheel shaft in order to release their positive engagement and to alter their angular position. When the metronome is in operation, the toothed wheel and the bell drum are kept in mutual positive engagement by releasable holding means.
