AT6915U1 - CHIN REST SCREW FOR VIOLIN AND VIOLA - Google Patents

Abstract

The invention relates to a chin rest screw for violin and viola. The use of titanium or a titanium alloy improves the tonal and technical characteristics of a violin or viola in such a way that the existing vibrations, impulses and overtones are not damped, but directly and precisely In addition, the use of an inert material does not allow any allergies, such as nickel allergy. The occasional coating with TiN or WC / C or CrC or CrN in the PVD process is used to brighten and differentiate the sound if necessary ,

   The invention relates to a chin rest screw for violin and viola.



   A chin rest screw is used to attach the chin rest 1 to the violin or
Viola to screw that violinist or violist with a wooden plate, the
Chinrest 1, which can hold the instrument more easily and the vibrations of the ceiling are not dampened.



   A chin rest screw consists of a bent set screw 2 with two
Right-hand threads 7, a lock 3 with a right-hand thread 7 and one
Left-hand thread 8 and cross holes 4 and a foot 5 with a left-hand thread 8 and an exemption 9 for the bottom edge of the instrument. To protect the instrument, the foot 5 and the chin rest 1 are covered with cork 6. In the drawing, a schematic section through a chin rest screw is shown; in a
Detail drawing of the foot 5 is shown without cork pad 6.



   The traditional chin rest screws are made of brass or another soft
Steel made and then nickel or gold plated.



  The invention is based on the fact that instead of damping materials such as relatively soft steel alloys or brass, titanium or a titanium alloy such as titanium grade 5 is used, and the impulses, vibrations and overtones are thereby better transmitted.



  The density of titanium or a titanium alloy and the vibration behavior are responsible for the fact that impulses, vibrations and overtones are not damped but are transmitted directly and precisely.



  The wear is much lower compared to brass because of its high strength. There is also the possibility of a nickel allergy with a nickel-plated chin rest screw, whereas titanium or a titanium alloy and the PVD coatings are inert.



  The success is clearly audible, since the response of the instrument and the brilliance as well as the carrying capacity of the sound are decisively improved, since there is practically no damping of the impulses, vibrations and overtones. In order to brighten and differentiate the sound, it is also possible to coat the chin rest screws with titanium nitride or tungsten carbide carbon or chromium carbide or chromium nitride, especially in the PVD process (physical vapor deposition process). The chin rest screws can also be colored by anodizing or thermal treatment.



  Furthermore, the chinrest screws only have three radial lock holes and not four like the conventional ones, which prevents damage to the frames during assembly and disassembly.



  The left-hand thread and the right-hand thread are covered by the initial release of the thread in the lock, which prevents the musicians' hair from getting caught.
