Description

The The invention relates to a stringed instrument with a means of a foot pedal Regulated and motor-controlled arc (preamble of claim 1).

The User group for the bowed instrument according to the invention are persons who play the violin before amputation of an arm Mastered virtuoso and now want to learn it one-armed. The Invention is based on the knowledge that after amputation a limb, the remaining limbs be trained to skills to which they previously were not used.

From the DE 1 075 928 B1 is a motor-driven bow for stringed instruments, such as violins, cellos or bass violin, known with circulating endless strings, with which a uniform, uninterrupted sound of any duration can be generated on the string instrument. The player sets the bow like a normal bow with his right hand on the strings, but does not strike, but with the help of a foot pedal, which operates a arranged in the motor circuit variable resistor, controls the engine speed and thus the rotational speed, via a transmission with the Motor connected string strands. The two string strands run in opposite directions to each other constantly in the longitudinal direction of the bow, whereby a better sound is achieved on the instrument so recorded. The player can also use only one strand at a time and then either move the arc or keep it still while playing. A "pianissimo" can be achieved either with very slowly circulating clothing or by corresponding normal bowing with the clothing stopped. On the other hand, a "fortissimo" is achieved by causing a faster or the fastest string circulation by depressing the variable resistor pedal. Preferably, an electric motor is used, wherein a flexible intermediate element, for example a flexible shaft, can be arranged between the electric motor and the driven disk. The motor and the rheostat are conveniently placed on the floor or on a suitable support near the player's stand, and in order to get the best result, it is necessary that only one string at a time touches the strings. Furthermore, it is necessary that the string of clothing, which is closer to the sheet holding player, from the Umlenk- to the drive pulley, ie counterclockwise, for example, and the player distant belt in the opposite direction rotates.

Furthermore, from the GB 449,064 a motorized stop mechanism for violins with a revolving endless band known. A similar auxiliary device is known from US 5,301,589 A known, which relates to a guide mechanism for violin bows.

A foot-controlled stop mechanism for guitars is out of the US 5,212,330 A known; This foot-controlled control mechanism is used in the foot control according to US 5,714,706 A further training.

Finally, out of the DE 23 35 498 A1 as an auxiliary device, a carrying device with shoulder straps and telescopic damper for violins known.

As the above assessment of the prior art are differently designed Auxiliary devices for Musical instruments known. A disadvantage of these known devices is that - for the function the operation of the musical instrument itself - constructive aids complicated and elaborate are designed and that the efficiency is relatively low. Therefore, in practice, despite urgent need one inexpensive Auxiliary device for one-sided arm amputated players of stringed instruments passing this through combined foot and head movements a virtuoso playing of the string instrument allows. This is particularly important because the musical instruments producing Industry as extremely advanced, development-friendly industry is looking at the very fast improvements and simplifications and put into action.

Of the The invention is therefore based on the object for one-sided arm amputees musicians to conceive a violin in which the still existing hand on the violin neck, the strings attack and the violin bow operation through combined foot and head movements is controlled, thereby creating a virtuoso Playing the string instrument much like is achieved with conventionally swept violins.

This object is achieved, starting from a stringed instrument with the features in the preamble of claim 1, characterized in that means for attaching a bow-carrying bow carriage at the player's head and first means for player-side control of travel of the sheet carriage and second means for player-side control Movement speed of the bow carriage or bow are provided, making unilateral arm amputated players both the placement of the bow on the one with the only Hand-held string instrument as well as a control of the bow of the bow is made possible by combinatorial movement of different body parts.

The each person must therefore brushing the violin means combined foot and head movements - and therefore actually the entire violin playing - re-learn, but remains you get the necessary musical sense, which is the foundation all, as well as this musical instrument operation is. Farther It is advantageous that playing with the violin according to the invention no overly large physical Burdens requires, so that even by such disabled new beginners the Violin playing can be learned.

at a preferred embodiment of the invention is, according to claim 2, as a means for Bogenschlittenbefestigung a helmet-like headrest element provided, which frontally in a forward-projecting elongated Spacer and guide element passes and which by means of chin strap positionally fastened to the player's head fastened is so that the respect the spacer and guide element transversely lying bow carriage in its position and angular position to the string instrument changeable by head movements is.

These Embodiment of the invention has the advantage that on the one hand on surprising simple way a largely fatigue-free and harmonious Control allows and on the other hand an individual yet reliable positioning is ensured.

In Further development of the invention is, according to claim 3, as a means for controlling the bow and / or the bow carriage by foot movement in each case a Fußzehwippe is provided, which by means of this articulated transmission linkage and mechanically connected potentiometer the toe movement into an electrical Control signal converts and wherein the two electrical control signals an electronic control unit supplied become.

These Development of the invention has the advantage that surprisingly simple way of getting a sensitive and accurate pedal control both amplitude as well as frequency of the sheet carriage is made possible.

Preferably are, according to claim 4, the toe-tip and the transmission linkage in housed a cavity of the shoe sole and the Fußzehwippe is acted upon by a tension or compression spring and as a gear configured, which in the tooth flanks of the elastically bendable in the transverse direction transmission linkage intervenes.

In Advantageously, this makes the foot control invisible in the shoe be housed, the wearing comfort of the user is hardly affected.

In Further development of the invention is, according to claim 5, on the the neck of the string instrument opposite side a support device across from the body of the player, which is designed such that during the Play by the only hand for the support device and thus the string instrument both the distance changeable as well as to the choice of strings is rotatable. Preferably, according to claim 6, the support device a telescopic tube which is both axially displaceable and rotatable, and a shoulder strap with a receptacle for the telescopic tube.

These Developments of the invention allow on the one hand a simple Adaptation to the height of the user and on the other hand, a direct visual contact with the bow or String selection during of playing.

at the violin of the invention the virtuoso playing of all strings is possible with only one arm, wherein the amplitude and frequency of the string instrument according to the invention (electronically controlled) of special, but inexpensive to realize Fußsteuerelementen in combination with a head-mounted, In amplitude and frequency variably controllable violin bow carriage linear motor is controlled. The rising and falling of the violin bow along the playing string longitudinal axis becomes here by means of a locked on the violin shoulder strap and on the violin self-attached hydro-telescopic damper allows. The required tensile / compressive forces are from the on the violin neck located, functional Hand of the respective user exercised.
