Control bar for rigid neck yoke, has sound absorption material and inclined flat section forming slope and comprising length calculated in combination and according to weight of slide, where slope has base emerging into transversal notch

摘要

The bar has a sound absorption material (17) and an inclined flat section (19) forming a slope with a base (20) emerging into a transversal notch (9) and a top (21) oriented towards an opening position of a movable bar. The flat section has a length calculated in combination and according to the weight of a slide. A sheet forming a counter weight is welded on the lower part of the mobile bar and extends in the direction of a bend bar. An independent claim is also included for a rigid neck yoke unit comprising a control bar.
