Description

The The invention relates to a sting system for violoncello or double bass.

Usually be great Stringed instruments, such as cello or double bass on one called "sting" Rod supported on the ground. The name sting comes from the fact that the rod at the end, which comes in contact with the floor covering is tapered. Sometimes finds Also the term "thorn" for such a Contraption.

at supporting greater Stringed instruments using a spine become sonority and Tonification partly influenced considerably by the type of flooring, on the sting while supported by the game becomes. So a soft ground tends to dampen, whereas, for example a stone floor can make the sound hard and inflexible. causal therefor is that due to the sting vibrations of the instrument body up transfer the underground become.

Out the prior art devices are known which consist of a Fastening device for a sting, the so-called "spiked pear", and a Sting itself exist. In these systems, the sting may be off the fastening device located within the instrument body at the Bottom is located, pulled out and on reaching the desired Length by means of be fixed to a screw.

There are sting known, which consist of solid material, the tip of the spine can be made of a different material than the shaft of the Sta chels. Furthermore, from the DE 6610297 U a barbed sting made of solid material known, in which the spiked steel tip is kinked.

In the FR 1 264 065 A a crooked or curved spike is disclosed, but which is attached as a separate device to the respective instrument and is not connected by a fastening device to the instrument. This device can therefore not be transported as part of the instrument, but represents a separate accessory to the instrument, which is also to be transported separately. The expense of using this device is significantly higher than with a device connected to the instrument.

The EP 0 108 113 B1 overcomes the disadvantages of in the FR 1 264 065 A disclosed device in which it discloses a device with a defined in a defined inclination sting, which is connected to the instrument via a further fastening means and can be inserted into the instrument.

An optimization of the sound level should be through in the DE 455 448 A revealed sting can be achieved. This is pierced or hollowed out in the longitudinal direction in whole or in part. In the cavity, one or more tubes of brass or other suitable material are attached, the lower opening is closed by a tip. Thus, a resonance chamber is created in the sting, which is in connection with the insertion of the spike into the socket with the resonance chamber of the instrument. The sound waves produced in the resonance chamber of the instrument penetrate into the hollow sting and are thrown back into the resonance chamber, whereby the sound-amplifying effect is achieved.

outgoing From this prior art, it is the object of the present Invention, a sting system and a sting for cello, double bass or similar To create instruments that make sound more diverse and advantageous possibilities open become.

Under diverse and advantageous options In the formation of sound in the context of the present invention influence options of the musician on the sound volume, the clarity and the timbre a sound. This is for sound improvement as well the sound magnification and allows so overall an extended timbre variability.

Is solved This object is achieved by the features of the independent claim 1.

According to the invention thereafter a sting system for Violoncello or double bass provided that from a holding device for attaching the sting system to the instrument (barbed bulb) and a sting, which in the holding device by a fixing device is kept adjustable in different positions, there is wherein the sting of at least two interconnected parts exists, which are at least partially telescoped, where these do not fit exactly, but correspond with each other with play and a portion of the spike in the fixture on the instrument is fixable and the other part as an end piece in contact with the ground comes. It is preferably provided that the coming into contact with the ground tail of the spine has a wreath on which the fixed in the instrument Part of the spine with at least two points, in which this to the ground runs out, rests.

In a particularly preferred embodiment, this is in contact with the soil towards the bottom towards the bottom. Furthermore, it is provided in this preferred embodiment that at least one part consists of a hollow body and / or the other part is made of solid material. Preferably, the solid part is the lower part, which tapers conically towards the bottom, and is thus designed as a solid tip. The lower part is also called tail.

ever after execution can the hollow part of the spine with recesses at variable intervals and with different sizes Be provided diameters. The recesses are preferably used to influence the vibration behavior of the spine. Furthermore, by the arrangement of the recesses, for example in a defined, repetitive pattern, affecting flexibility or flexibility of the sting can be taken in one or more directions. Preferably, as recesses holes or slots at variable intervals and with different sizes Diameters provided according to the invention.

Of the Sting possesses through the arrangement of the recesses, as well the tips of the upper part running towards the bottom have different orientations with regard to the influence on tone formation. So can the upper one Part of the sting even with only one of the two tips on the Wreath of the tail rest, depending how the spike is inserted into the instrument towards the ground.

is a point of the upper part of the sting directly between ground and in the upper part located tail, so is due to the game between the upper and lower part of the spine, the inclination of the spine in its use and the weight of the instrument only the opposite "upper" tip resting on the wreath. Are the two tips arranged laterally, that is rotated by 90 degrees, so both tips are on the wreath, because the weight of the instrument is distributed equally between the two tips becomes.

Out For this reason, it is in a sting with two tips according to the invention of the upper part of importance, in which orientation the sting over the Spiked pear is connected to the instrument. One turn around 45-90 degrees (in the axis) causes other effects in the sound, as one for another 45-90 Degree (in the axis) twisted attachment of the spine in the instrument.

For the tail of a According to the invention sting is in a further embodiment provided that this consists of at least two parts. So is the wreath and / or the tip as a separate part reversible with the tail connected. By this measure will provide maximum flexibility in the Use of the sting according to the invention guaranteed.

Of another is provided according to the invention, that upper and lower part of the spine though solid, but quite reversibly connected to each other. This will be the possibility opened, that different upper and lower parts are combined can, the for a particular instrument or condition, e.g. B. a certain background or special acoustics of the performance venue, necessary.

It can so combined with a lower part different upper parts, for example, have different outer diameter and thereby be used with other or existing bark bulbs can. But it can also be combined with an upper part of various tails that different tapered or made of different materials are.

to Connection of the two parts of the spine according to the invention are preferably a bolt or a threaded connection, magnetic parts Ball joint or a plug or bayonet connection provided. But there are also all other compounds conceivable, suitable are, the two parts fixed or firm, but reversible below Receiving the construction-related game to connect with each other. It is expressly provided according to the invention that different tips with the stick of the spine, in the Instrument is attached, can be connected.

Farther may be a sting according to the invention also be constructed so that the two part associated with game temporarily firmly and without play can be connected to each other.

to Magnification of the soundboard the prick of the invention Can on the tail opposite side of the upper part of the spine an additional rod-shaped Part attached, which in the attachment of the spine on Instrument by means of the barbed bulb, into the sound box of the Instrument reaches into it. This part is without play with the upper one Part of the spine connected and may be a hollow body or even solid Be material.

The parts of the spine according to the invention are preferably made of metal, metal alloys, carbon, aluminum, titanium or wood or a combination thereof. However, the different parts do not have to be made of the same materials be but can also be made of different materials.

The barbed system according to the invention or also the sting according to the invention can also with all other instruments with a resonance space for supporting the Instrumentes are used on the ground.

One fundamental Problem with the use of instrument spines is, as already described that through this a mechanical connection to the ground is created and so always transmitted vibrations to the ground become. This transferred to the ground Cause vibrations to a loss of volume and dynamics in the tone formation of the instrument.

This Disadvantage is eliminated by the fact that the instrument by the barbed system according to the invention, respectively the sting according to the invention even decoupled from the ground. This decoupling will give a wider range of tone formation in terms of dynamics, volume, clarity and timbre.

So is for example when using the spine according to the invention or barbell system playing clear and in large halls sustainable tones in pianissimo much easier. In addition, the possibilities are the timbre a tone to influence by the use of the sting of the invention or sting system expanded. For The musician expands the spectrum in which he influences can sound on the tone.

When essential part and core of the invention is a mechanically movable attached part at the bottom of a tube, which z. B. is connected by a bolt to the tube and essentially the sting of the invention forms, to look at. The lower part of the spine itself has a Type wreath or collar on which preferably two tips of the Put on the pipe. Through this mechanically easy moving connection the instrument is decoupled from the ground. At the same time arises between the lower and upper part of the spine a vibration behavior, that has a positive effect on the sound quality effect.

In contrast to that in the DE 455 448 A disclosed in the present invention, the hollow part of the spine is designed completely different because of the completely different purpose that is to be achieved with the spine according to the invention. Thus, in the cavity of the spine according to the invention are no conically shaped tubes, which are also connected to the resonance chamber of the instrument.
