Description

Accordion
Technical Field
The invention relates to an accordion, in particular a hand-pulled accordion or other hand-pulled musical instrument, having a treble mechanism with a keyboard, in which a filling of a housing part carries or has a sound column and is provided with corresponding sound holes which can be covered by a sealing body which can be operated by means of the key levers of the keys of the keyboard.
Background
DE 913493 discloses an accordion with a treble part in which the sound columns are arranged in a row on the underside of the filling. The keyboard or keyboard may be a piano keyboard or keyboard with keys or keybuttons that control the air passages of the sound column by means of the levers and the dampers in a manner known per se. The sound post and the lever for operating the damper are covered by a cover attached to the keyboard. On the lower edge of the treble part, a bellows frame is arranged on which bellows are arranged.
An accordion is known from DE 3638517C 1, which is intended to be held more naturally by the arms when playing. For this purpose, a treble part is provided, the treble part having a finger plate with a keyboard arranged adjacent to the front side of the accordion, which finger plate extends the front side and forms an angle of 40 ° to 50 ° with the front side. The inclined position thus achieved frees the player from an unnatural arm holding posture. A filling is arranged in the instrument housing essentially perpendicular to the fingerboard, said filling being provided with sound holes and carrying a correspondingly associated column. The frets have corresponding reeds that respond to a plucking or pinching when the damper is lifted from the soundhole by operating the keys. The key can be depressed in the direction of the fingerboard against the force of the spring and is rotatably supported in the key holding structure. Furthermore, the keys are connected to a key lever having a damper, also called a plug damper, on its end portion to open or close the tone holes of the sound column by a flip motion.
In the known hand musical instruments, the sound holes are thus opened or closed by means of outwardly moving pin/pin dampers (Ventilklappen) through which air can flow out of the column or into the column. The opening or closing of the bolt/bolt damper is usually effected by means of a lever or lever, so-called piano key. This technical solution has been created in the years of development history of the accordion and follows a playing keyboard that is bent to a large extent with respect to the instrument.
Since the previous embodiments force a certain minimum space requirement in the instrument, this makes the instrument correspondingly large. The instrument is also heavy due to the necessary lever mechanism. It is also disadvantageous that this arrangement permits only a relatively small opening angle of the sound bolt, which makes flawless sound development (klengentfantring) largely limited to the low-pitched range. This makes it possible to choose the sound holes large in order to compensate slightly for this effect.
Disclosure of Invention
The object of the invention is therefore to provide an accordion or other hand pulled musical instrument with a more compact design of the treble mechanism.
The object is achieved by an accordion according to the invention with a treble mechanism having a keyboard, in which a filling (F ü llung) of a housing part carries or has a sound column (Stimmstock) and is provided with a corresponding sound opening which can be covered by a sealing body which can be actuated by means of a key lever or a sound lever (klavischerishebel) of a key of the keyboard, according to which the sealing body is designed as a sound peg disk or a sound seat (ventileller) respectively, which covers the corresponding sound opening by means of a sound peg seat or a valve seat (ventililtz) on the side facing the sound column, for which purpose at least one thrust link or a link (Schubstange) respectively carrying the sound peg disk at the free end is articulated on the key lever respectively, which serves as an actuating element for performing an up/down movement along an actuating axis.
An accordion or other hand pulled instrument is thus provided in which the pegs of the frets open not outwards, but inwards towards the frets. The solution according to the invention is therefore based on a departure from previous solutions with dampers which use covers fixed to the lever for bearing on the soundhole. The solution according to the invention is based on the use of a connecting rod or a tumbler rod which carries a tumbler disc which is pressed onto the sealing seat on the side of the filling facing the sound column and is lifted from the sealing seat in the direction of the sound column by a lifting movement. This design allows a more compact design, which can additionally be designed ergonomically, so that the ergonomically handling possibilities are improved. In addition, a modular construction is achieved, for example, in order to produce a button-type or piano-type hand-pulled instrument with low effort. The treble mechanism can then be manufactured using injection-molded parts made of plastic material.
The following advantages are derived in particular with respect to the known solutions. A long and heavy angle mechanism is no longer required. The pegs can be placed directly under the keys, thereby achieving a significant reduction in the space and volume of the instrument. The keyboard can be integrated directly into the housing of the instrument, i.e. the fingerboard (Griffbrett) for the mounted or outwardly projecting keyboard can be eliminated, which forms a decisive improvement in the ergonomics of the instrument. A more natural holding with the arm is achieved when playing the instrument, which is an important advantage in terms of health, especially for children at the age of development. In addition, a significant reduction in the overall weight of the instrument can be achieved thereby.
The opening and closing of the sound holes can be effected depending on the design of the instrument, i.e. depending on the layout of the keys and the positioning of the individual sounds on the frets or spring plates, ideally by direct connection of the keys to the peg disks or by different types of compact configurations. This brings about the following advantages in addition to the above-described advantages. Instead of a limited opening angle, a greater opening travel is achieved. Linear and straight-line movement of the sound bolt disc is realized.
The disturbing noise of the part closing the sound hole, i.e. here the tumbler disc, when it reaches the rest position can be avoided, since no key stops are required anymore and thus the impact noise of the keys is eliminated. But the sealing material that can be used for the sound bolt can create a cushion against impacts. The brake device, which increases the force for actuating the keys and is disadvantageous in particular for fast and child-friendly playing, can be dispensed with. Furthermore, the sound emission position and thus the end position can be adjusted for the movement of the key for opening the sound hole by means of the selectable opening distance. The movement of the keys, i.e. the key lift or stroke (Tastenhub) and the tumbler disc lift or stroke, can be combined into a single moving part and selectively varied. The keystroke and the phonation dynamics can be directly correlated in this way.
Furthermore, the sound hole opened/closed in the manner according to the invention creates a new possibility for the design of the sound hole, the filler and finally the sound column. In contrast to the known solutions, in which the bolt damper can only open the sound opening in a wedge-like manner due to the long rod, a completely uniform opening of the sound opening can be achieved in the invention shown here. This also reduces and balances the flow resistance of the outgoing or incoming air, for example. The sealing of the plug disk against the sound hole can be achieved in different ways by a linear movement process. For example, sealing lips, conical seals, etc., can be used in contrast to known flat seals. A lower sealing force is thus required, since the action of force in the sealing disk can also be effected centrally, rather than by lateral lever action, as in the case of a flap fixed to a lever.
Also resulting in lower material costs and no significant sound aspect due to the surface properties of the sealing material. The uniform opening of the sound holes, which in addition increases the distance between the peg disks and the sound holes, can significantly improve the sound production of the instrument. The sound can simply be better expanded.
In addition to the improvement in the sound production or timbre, at the same time, an increase in the sound volume or loudness can thereby be achieved with the same or even a reduced air requirement. The effect of different sound hole shapes on sound expansion and on reduction of flow resistance can be utilized in a wide range. The solution according to the invention described for the treble mechanism can also be transferred to the bass mechanism.
Further advantages and embodiments of the invention can be derived from the following description.

Detailed Description
The present invention relates to an accordion, in particular an accordion or other hand pulled musical instrument.
The accordion shown in fig. 1 has two housing parts 1, 2 which are connected to one another by bellows or bellows 3. The housing part 1 has a keypad 4 as part of a treble mechanism 10 arranged in said housing part 1. The treble mechanism 10 further comprises a fret 5. Each fret 5 has a spring plate 6. Furthermore, each sound post 5 corresponds to at least one sound hole 8 in the filling 9 of the housing part 1, which can be closed by the sound bolt 7. The housing part 2 may be arranged to house a bass mechanism (not shown).
The illustrated accordion thus comprises a treble mechanism 10 with a keyboard 4 in which the filling 9 of the housing part 1 carries the post 5. The plurality of frets 5 are generally arranged in one or more rows arranged parallel to each other as shown in fig. 7 and 8, depending on the selected number of lower keys 11 and upper keys 12 of the keyboard 4. This applies correspondingly to the case of a keypad.
As shown in fig. 2 to 6, the filling 9 is also provided with corresponding sound holes 8 which can be covered by a sealing body of each individual sound bolt 7. The key 7 can be operated by the key levers 13 of the keys 11, 12 of the keyboard 4.
According to the invention, the sealing bodies of the sound pegs 7 are each designed as a sound peg disk 14, which covers the respective sound hole 8 by means of a sound peg holder 15 on the side 16 of the filling 9 facing the sound post 5. The associated key lever 13 is used for actuating the tumbler discs 14, to which at least one connecting rod 17 is respectively articulated, which in each case carries the tumbler discs 14 at the free ends, said connecting rod 17 serving as an actuating element for performing an up/down movement along an actuating axis. The depression of the keys applied to the keys 11, 12 while playing the instrument can be directly transmitted as a lifting motion to the peg board 14. The force deflection by the knee lever can therefore be completely dispensed with. The term "key lever 13" is understood according to the invention in terms of its function as a connecting element between the keys 11, 12 or treble keys (not shown) and the peg disk 14 as a closing element for the sound hole and thus as part of the treble mechanism and not in its hitherto known corner structure for operating a damper.
Importantly, according to the invention, the peg disk 14 is moved downwards in the direction of the sound post 5 in order to open the soundhole 8. Thus, when the key is depressed, the downward movement of the key 11, 12 can be converted into the downward movement of the peg tray 14 and the opening of the peg 8, whereby the operating characteristics forming a straight line can be adjusted. At the same time, the spring pretensioning of the keys 11, 12 of the keyboard 4 can be simultaneously used for spring pretensioning of the tumbler discs 14 on the tumbler seats 15. The operating shaft may be a straight operating shaft. The connecting rod 17 can thus be designed as a push rod below the keys 11, 12 if the respectively associated key 11, 12 is pressed in order to play the respective sound and thus open the respectively associated tone hole 8 by lowering the connecting rod 17. The use of the same spring pretension makes it possible to directly relate the key movement to the tumbler disc movement in terms of design technology. The shape of the spring-loaded tumbler disc 14 can be selected and can be formed, for example, by a flat seal.
The tumbler discs 14 are advantageously each arranged in an articulated manner on a connecting rod 17. It is also possible to configure the key levers 13 integrally with the curved convex portions as the links 17, respectively. On the side of the filling 9 facing the fret 5, a sealing material (not shown) may be provided, which is able to form a fret seal in the region of the fret holder 15. The sealing material can also constitute a shock-absorbing structure for the keys 11, 12 in the transition to the rest position, i.e. when the sound bolt 7 is closed. Alternatively or additionally, the sealing material can also be provided, for example directly injection-molded, on the sound bolt disk 14, preferably for the function of a radial seal or a face seal.
The key lever 13 is mounted in a manner known per se on the filling 9 in a manner such that it can be pivoted or deflected by means of a spring device 18. For this purpose, the key levers 13 are preferably arranged so as to be able to be tilted about an axis 19 and are each connected to a key 11, 12. The key levers 13 are preferably each designed as a strip-shaped rib which forms a lower structure with a top support for supporting and positioning the keys 11, 12 of the keyboard 4. The respective key, whether it is the lower key 11 or the upper key 12, can then simply constitute a rest member (Aufsetzteil) for the resiliently supported piano key 13. The spring means 18 can at the same time serve as a spring articulation of the keys 11, 12, whereby the keys 11, 12 operated by pressing spontaneously return into their initial position after release.
According to a further embodiment shown in fig. 9, the key lever 13 is configured as a lower key whose spring device 18 with a spring 20 is configured separately from a spring device 21 with a spring 22 for spring-loaded keys 11, 12. A sealing material 25 is also applied to the filling 9 in the region of the sound bolt seat 15.
Alternatively, the keys 11, 12 and the key lever 13 can each also be designed as a single component, i.e. the keys 11, 12 can form lever arm sections of the key lever 13, from which lever arm sections extend links 17 as further lever arm sections of the key lever 13, on which lever arms a tumbler disc 14 is articulated. The lower structure of the keys 11, 12 may also be configured as a key lever 13.
The keys 11, 12 and the associated key levers 13, which are part of the key mechanism, for moving the tumbler discs 14 between a rest position, in which the sound holes for generating sound are closed, and a sound-emitting position, in which the sound holes are open, preferably each have at least one common direction of movement which can be transmitted to the respective connecting rod 17 when the keys are pressed. This applies irrespective of whether the keys 11, 12 are configured as keys or key buttons.
Fig. 10 and 11 show an embodiment in which a stop element 24 is provided, which is a path limiting structure (wegbergenzung) for depressing the keys 11, 12. This stop element 24 can be formed in a simple manner by a pin onto which the piano key 13 as part of the key 11, 12 can be moved and thus at the same time forms a path-limiting structure for the connecting rod/tumbler rod 17 of the tumbler 7. The width of the opening of the sound pegs can thus be controlled simultaneously and jointly by the stop elements 24.
According to the invention, it can also be provided that the filler 9 with the sound hole 8 simultaneously forms a finger plate for the installation of the key bar 13 of the keyboard 4, which can then be pressed against the force of in each case one spring 20 of the spring device 18 in the direction of the finger plate formed by the filler 9 and is mounted in the key bar holder so as to be pivotable about the axis 19.
As shown in fig. 8 and 9, the sound column 5 may be constituted by an air duct, on the air duct body of which the spring plate 6 is mounted and the air duct opening of which is directed toward the key lever 13 on which the key is mounted. The air duct openings are arranged in a plane parallel to the keyboard 4.
Furthermore, as shown in fig. 5 and 6, the frets 5 may be arranged in an angular region forming 90 ° to 135 ° with respect to the filler 9, in particular in rows on the bottom side of said filler 9. This enables an optimum use of the space in the housing part 1. A bass mechanism may be provided. The bass mechanism is configured in correspondence with the structure of the treble mechanism 10.
Thereby providing a modular construction.
