Spring hand travel device

The invention relates to a spring hand trajectory training device comprising an elongate member 2 imitating a spring, which is conveyed in a straight line back and forth by means of a guide 1 corresponding to the length of the spring without sound generation.

Controllers based on the actual playing situation are already known. In this case, the guide has had to be constructed relatively short, i.e. to correspond to the width of the fingerboard. Effortless transport of the spring against the tongues also requires a certain amount of clearance between the guide and the spring. Due to these two factors, the trajectory allowed by the guide is not a straight line, but a sector that expands towards the extreme position of the tension spring.

When the playing requirement has been waived in the teaching device according to the invention, the guide 1 can be constructed to the length of the path of movement of the spring hand and the spring imitating member 2 in turn corresponds to the grip width of the fingers from the spring. Thus, the trajectory is a straight line determined from point to point.

However, the main difference between the previously known controllers and the teaching device according to the invention relates to the physiology of motion performance: In all controllers requiring playing, the starting point is the erroneous idea of motion, according to which the controller mechanically opposes the performance. In the device according to the invention, the guide 1 does not have to be attached to the player, whereby the linear transport of the spring imitating member 2 along the groove of the guide 1 takes place completely passively without a predictive image of movement.

Once this passive movement performance, which is subjectively perceived as a strongly outwardly curving track, has been stabilized, training can be continued under conditions corresponding to the playing situation by attaching the controller 5 to the player.

The characteristic features of the invention are set out in the claims.

The basic model of the device is shown in Figure 1. and the modification to be attached to the player in Figures 2-3. The following symbols have been used for parts of the invention: 1. a board with a straight groove acting as a guide 2. a member to be transported in the guide groove 3. a base 4. a spacer 5. a tubular guide 6. an axial plane 7. a shaft perpendicular to the base 8. a sound generator indicating the base a locking member 9 of the rotation of the guide in the plane, which prevents the sliding part built into the guide 10 of the rotation of the chassis in the plane. parallel to the 15. player cover 16. fingerboard 17. talla

The training with the basic model takes place in such a way that the guide 1 is placed transversely in front of the pupil and the pupil 3 81696 is asked to carry the spring imitating member 2 on its two tips back and forth along the groove. The error occurs in the form of the member 2 jumping out of the groove of the guide 1.

In the variant to be installed in the player, the tubular guide 5 is fixed by means of a base 3 between the fingerboard 16 and the sole 17 of the player cover 15, and axially rotated perpendicular to the longitudinal axis of the player in a sector corresponding to the tongue planes. In order to be able to move the guide 5 in this sector at the same time as the spring imitating member 2 is conveyed back and forth in a straight line, the spring imitating member is constructed from a slide part 10 placed inside the guide 5 and an external gripper 11 attached thereto.

By axing the guide 5 to rotate also in the plane of the base 3 by means of the spacer plate 4, and by articulating the gripping piece 11 on the slider part 10 perpendicular to the axis 12, the trajectory can be practiced without forced control on audible signals. These rotations are locked in the forced control position by means of two locking members 9, 14, whereby the forces applied to the player can be minimized.
