Definitions

  • the present invention relates to a harmonica or accordion according to the preamble of claim 1. More specifically, the present invention is concerned with the treble and bass mechanics as well as the arrangement and number of voice sticks and helicon tuning plates of a harmonica or accordion.
  • the mechanical actuation of the button is transmitted via a lever linkage with at least one hinge axis on a flap.
  • This flap opens a correspondingly provided opening.
  • the so-called "Styrian” harmonica is the characteristic form of a diatonic harmonica, which is used in folk music, especially in Bavaria, Austria, South Tyrol and Slovenia, and has decisively shaped it ,
  • the actual mechanism is constructed in a grip area that has been largely recessed, whereby the individual keys are fastened to a stainless steel axle, for example by brass straps.
  • a plate in which holes for the operation buttons are inserted so that only the operation buttons are visible.
  • the key levers are mounted on a common axis, in rare cases on instruments with five rows of keys on two axes.
  • the flip cover (s) are turned outward with the bass or accompaniment key depressed, opening openings that lead to the bass and accompaniment voices.
  • the bass keys are supported by recesses on the fingerboard of the bass section in translation guides.
  • Two-, three- or multi-choir voices are generally incorporated into the treble part of harmonica and accordion.
  • Two-guitars in treble parts means that when a key is pressed to produce a specific tone, two tongues are vibrated whose frequencies differ by a beat of up to six hertz.
  • the bass usually consists of a basic bass and a matching octave of the accompaniment set and the accompanying chord composed of three individual tones of the accompaniment set by means of a mechanical system of transmission shafts, button slides, shaft and driving pins.
  • the basses of the diatonic harmonica are subdivided according to the type of sound produced into tightly composed bass parts and accompanying chords.
  • helicopter basses The special sound of so-called helicopter basses is based, among other things, on the use of large tongues.
  • monozygotic and polychoral for example, depending on the number of tongues vibrated to produce a sound.
  • two-notes, basses or voices are always only one-part).
  • two tongues are vibrated by the pressure and suction air at two-key Helikonbässen at the touch of a button, for example, the fundamental tone C and its upper octave c.
  • a well-known in the art type of construction of the bass part of a harmonica or accordion with Helikonbtreun uses voice plates, in which two reeds already (reeds and its upper octave) are provided for both Beerströmraumen. These reeds have four reeds.
  • Other known designs use two separate voice plates, one producing the fundamental tone in both directions of airflow, and the second usually generating the first upper octave in both directions of airflow. These reeds each have two reeds.
  • the invention aims to provide a harmonica whose mechanics are simple and functionally and arrangementally better than in the prior art.
  • the treble mechanics has in the previously known constructions both in “open” and “hidden” execution the disadvantage that in a equipped with several rows of keys harmonica due to the different spacing of the key rows as well as due to the different distance of the voice sticks to the axes not only different lever lengths, but also provide particularly long lever lengths for outer rows of keys.
  • the lever lengths and leverage ratios are exemplified by a 4-row harmonica with "open” mechanics in Fig. 2 and shown as an exploded view of the treble lever in Fig. 3b. Corresponding designs are also common with two, three or more than four rows.
  • the voice sticks are sorted in reversed order to the previously known construction on a purpose specially shaped treble so that using a number of button rows preferably the same number of axes, which are positioned so that the distances to keys and keys are at least substantially the same across all key levers, the key lever lengths and keys lever length ratios are insignificantly different, at least substantially the same, over all key levers of the entire keyboard.
  • the outermost rows of keys thereby serve the openings of the vocal stock nearest the back of the instrument, the second outermost row of keys that of the second closest to the back, and so on, to the innermost row of keys which serve the openings of the vocal stock closest to the front of the instrument.
  • the bass mechanics of accordions and accordions have a number of joints, swivel axes and other, design-related Transmission elements mechanical disadvantages in the form of friction at these joints and / or used push and slide transmissions, as well as by torsional stresses of the linkage along the wire axis.
  • the increased elasticity of a wire or rod in torsion about or along the wire axis causes a tactile and undesirable softness of mechanical transmission from the bass button to the flap cover.
  • every joint required for transmission shows signs of wear after some time, which do not allow a permanent and exact function of the mechanism.
  • the arrangement and use of rotary and transmission elements is shown in the case of the diatonic harmonica using the example of the Styrian harmonica in FIG. 2 and in the case of the chromatic accordion in FIG.
  • the bass mechanics changed so that in the case of diatonic harmonica no joints and no rotation of a transmitting element and more by the same application in the chromatic accordion a maximum of three rotatable or steerable designed transfer elements between the bass or accompaniment keys and the associated flap lids occur.
  • the flap opening is executed inwardly.
  • the transmission linkage is a pure push linkage which has no articulation or rotation elements and, in the case of chromatic instruments, is reduced to substantially fewer transmission elements in comparison to previous designs.
  • the conical shape of the flap lid, which sinks when closing in the partition wall, allows a reduction in the space requirement of the lid inside the instrument to the passageway between shaft walls and To open flap covers for the air flow as far as possible.
  • the sorting of the bass control panels in the bass section and the Kanzellensammlung and air ducts designed so that without exceeding the conventional sizes, an installation of 12 apprisc culinaryigen Helikonbêtn in the chromatic accordion and in the case of diatonic harmonica an extension of the range on the one chromatic scale is possible.
  • this is accomplished by incorporating two separate reeds, one producing the fundamental and the second either the same root or first octave thereto. It is to create the condition that no component, which is responsible for generating the bass tones, protrudes into the bellows cavity and the width of a bass shaft does not exceed the dimension of a monochrome Helikonbassstimmplatte.
