Description

[0001] The invention relates to a hand-pulled instrument with a bass mechanism. Such a hand-pulled instrument comprises a key lever, which can preferably be actuated at least indirectly by means of an operating element and is designed to open and / or close at least one tone hole.

[0002] The invention further relates to a method for assembling a hand-pulled instrument.

[0003] The invention further relates to the use of a slider for coding at least one tone of a bass mechanism of a hand-pulled instrument.

[0004] Such hand-pulled instruments are well known and can also be referred to as concertinas or accordions. In particular, such a hand-pulled instrument is an accordion. Such hand-pulled instruments may have a bass section or bass mechanism, particularly on the left side as seen from the player. These usually have buttons as control elements.

[0005] The task of the bass mechanism is to translate the actuation of a control element into the actuation of one or more corresponding keys, which in turn release a stream of air that flows through the respective reed plates. The reed plates are permanently installed as part of the soundboards and are each actuated by directing an air stream, created by pulling or pushing on the bellows of the hand-pulled instrument, to a reed plate. For this purpose, the base plate on which the bass mechanism is mounted has tone holes corresponding to the respective reed plates, through which the air stream can be directed. Each tone hole is covered by a key, which, depending on its position, allows the tone hole to be opened and / or closed.

[0006] Such bass mechanisms comprise, for the functional connection of the operating element to the key lever, a slider with a driver that can be actuated by means of the operating element, a shaft that can be set in a rotary movement with a shaft pin that can be acted upon by the driver, and the key lever that can be acted upon by a shaft hook of the shaft and is designed to open and / or close at least one tone hole.

[0007] The assembly of such bass mechanisms is complex and has so far been carried out during the assembly of the hand-pulled instrument and within a base body of the hand-pulled instrument that carries the bass mechanism.

[0008] The object of the invention is, among other things, to simplify the manufacture and assembly of such hand-pulled instruments and to achieve the most compact design possible. To achieve the stated object, the features of claim 1 are provided according to the invention. In particular, to achieve the stated object in hand-pulled instruments of the type described at the outset, the invention proposes that the key lever be rotatably mounted in a holder which is arranged at a distance from a base plate containing the tone hole.

[0009] On conventional hand-pulled instruments, the key levers are mounted directly on the base plate containing the tone hole. The base plate must therefore provide sufficient space between the tone holes for mounting the key levers, for example, on a bracket. This limits the number of possible tone holes.

[0010] By mounting the key levers in a bracket spaced apart from the base plate, the base plate can accommodate more tone holes than before. This is particularly advantageous when the bass mechanism is intended to form a convertor bass.

[0011] A hand-pulled instrument with a convertor bass features an additional switching element that allows switching between different tone layouts, such as a stradella bass layout and a melody bass layout. Such bass mechanisms feature an additional template covering the base plate, which opens or closes various tone holes depending on its position.

[0012] In an advantageous embodiment, it can be provided that the hand-pulled instrument further comprises a slide, which can preferably be actuated by means of the control element already mentioned or an operating element, with a driver, which acts on the flap lever, preferably via a shaft which can be set in a rotary movement and has a shaft pin which can be acted upon by the driver and a shaft hook of the shaft.

[0013] The bass mechanism of the hand-pulled instrument can thus be used to produce a more diverse selection of tones and / or chords, which would not be possible by directly actuating the key levers using the respective control elements due to the limited space within the hand-pulled instrument.

[0014] In an advantageous embodiment, for which protection is also claimed independently, it can be provided that a support is arranged between the slide and the tone hole, which support rotatably supports the key lever and / or a shaft, for example the one already mentioned.

[0015] The support can, in particular, have the previously described holder for the key lever. The support therefore enables, in particular, the previously described configuration, according to which the key lever is rotatably mounted in a holder arranged at a distance from the base plate. For example, it is possible to pre-assemble the key lever and / or the shaft on the support before the support is installed in the hand-operated instrument. This considerably simplifies the manufacture of such hand-operated instruments.

[0016] In addition, it can be provided that the carrier is arranged between the shaft and a bearing of the flap lever.

[0017] For example, the flap lever and the shaft can be mounted on different, opposite sides of the support. This simplifies the assembly of the flap lever and the shaft.

[0018] In an advantageous embodiment, for which protection is also claimed independently, it can be provided that the shaft is rotatably mounted on the carrier by a shaft holder.

[0019] The bearing of the shaft can thus be designed advantageously.

[0020] In an advantageous embodiment, it can be provided that the shaft holder has an upper part and a lower part, which can be connected to one another in a force-locking and / or form-locking manner by means of a fixing element.

[0021] Thus, the shaft holder can be assembled advantageously and, in particular, detachably. For example, the lower part can already be mounted on the support, and the shafts can be placed thereon first, followed by the upper part. The upper and lower parts can preferably have rounded recesses for receiving the shafts. The lower and upper parts can differ in the number of recesses provided on them.

[0022] In addition, the fixing element can be pin-shaped.

[0023] For example, the fixing element can simply be guided through the upper part and / or the lower part to secure them relative to each other in a force-fitting and / or form-fitting manner. The fixing element can, for example, be guided orthogonally to the shafts. The fixing element can also have a diameter that approximately corresponds to that of the shafts. For example, the fixing element can be arranged between two shafts whose ends abut against the fixing element.

[0024] Alternatively or additionally, it can be provided that the upper part is spaced from the lower part when the shaft is inserted.

[0025] For example, a distance between the upper and lower parts can be defined by the diameter of the shafts located between them.

[0026] In an advantageous embodiment, the upper part can be provided with a snap-on connection. Alternatively or additionally, the lower part can be provided with a snap-on connection. For example, the upper and lower parts can be snap-on to each other or to other components.

[0027] This allows the shaft to be advantageously fixed in a rotatable manner.

[0028] Alternatively or additionally, the upper part and the lower part can be integrally connected to each other at at least one point. For example, a type of clamp can be formed that can rotatably secure one or more shafts. The clamp, for example, the lower part, can be fixed to the carrier.

[0029] In an advantageous embodiment, it can be provided that the upper part and / or the lower part each have at least one bore for receiving the fixing element.

[0030] Here, too, the fixing element can be pin-shaped. For example, the lower part can have a larger number of holes than the upper part to allow for variable positioning of the fixing element.

[0031] Alternatively or additionally, it can be provided that the fixing element can be connected to the lower part in a force-locking and / or form-locking manner by means of a bayonet lock.

[0032] This allows the shaft holder to be easily assembled and disassembled. The fixing element can, for example, have a groove for a screwdriver, which allows the fixing element to be easily secured and released.

[0033] In addition, it can be provided that the fixing element is connected to the upper part in a force-locking and / or form-locking manner when connected to the lower part and the shaft is inserted into the shaft holder.

[0034] If the fixing element is fixed to the lower part by means of the bayonet lock, it can also fix the upper part in its position, for example by means of a collar formed on the end opposite the bayonet lock.

[0035] In an advantageous embodiment, for which protection is also claimed independently, it can be provided that several flap levers are designed identically.

[0036] In particular, it can be provided that at least half, preferably at least three quarters and particularly preferably all of the flap levers are designed identically.

[0037] In particular, the fact that the key levers are mounted at a distance from the base plate, independent of the position of the tone holes, makes it possible to produce several identical key levers. This significantly simplifies manufacturing, storage, and assembly costs.

[0038] In an advantageous embodiment, it can be provided that the shaft hook acts on the flap lever at a connecting lever of the flap lever, that the shaft hook engages in a recess in the connecting lever, and that the connecting lever has at least two identical recesses. Because the connecting lever has at least two identical recesses for the engagement of the shaft hook, several flap levers can, for example, be designed identically, as described above. The flap levers can then, if necessary, be acted upon at different points on their connecting lever. It is also possible to shorten the connecting lever if this is necessary for or during assembly, for example to avoid collisions between different shaft hooks. The flap lever and connecting lever can, for example, be formed as a single piece and / or be permanently attached.

[0039] Another advantage is that the described design allows for reusability of the flap levers. The flap levers can even be used in different positions, particularly when multiple flap levers are identically designed. Such reusability is possible even if the flap lever needs to be loaded at a different location on its connecting lever, since the connecting lever has several similar recesses.

[0040] In an advantageous embodiment, it can be provided that the driver of the slider has a predetermined breaking point.

[0041] In this way, the manufacture of slides can be simplified by standardizing the slides. This allows universally applicable slides with a standard arrangement of drivers to be manufactured. These slides can have more drivers than necessary for their intended use. If necessary during assembly, individual drivers can be easily removed at their predetermined breaking point. This can be done, for example, if a shaft pin of a tone assignment is located adjacent to a driver, which should not be addressed by the control element belonging to the slide.

[0042] Alternatively or additionally, the slider can be guided by a guide element. The guide element can be detachable and / or pluggable into a guide part.

[0043] This allows the slide to be easily mounted for sliding movement. This also ensures that the slide and its driver always act on the desired shaft pin.

[0044] In an advantageous embodiment, a return spring acting on the flap lever can be arranged between the flap lever and the support. Alternatively or additionally, the return spring can be designed as a compression spring.

[0045] The return spring ensures that an actuated control element returns to its original position after being released. The return spring can be positioned between the key lever and the support in a particularly space-saving manner, leaving space on the base plate for the tone holes.

[0046] In an advantageous embodiment, it can be provided that at least one slider has at least one driver that does not act on a shaft pin. Alternatively or additionally, it can be provided that at least one slider has at least one driver that is arranged at a distance between two adjacent shaft pins.

[0047] Thus, a slider can have at least one driver that is not required in an installed bass mechanism. To enable reusability of the sliders, however, uniform sliders can be produced that have drivers that, in their position, do not contribute to the installed tone pattern. If the slider is reused in a different position, particularly in a different bass mechanism, the previously unused driver can act on a shaft pin and thus contribute to the tone pattern.

[0048] According to an embodiment of potentially independent inventive quality, at least two shafts can be held by identically designed shaft holders and / or by a shaft holder that has predetermined breaking points between its shaft receptacles. This design of the shaft holder enables simplified, space-saving assembly and flexible use.

[0049] In an advantageous embodiment, it can be provided that a distance of a flap fastened to the flap lever in at least one direction, preferably in two directions, to a next flap fastened to a further flap lever is smaller than an outer dimension of the flap in the respective direction.

[0050] The bass mechanism can therefore be designed very compactly. This is made possible in particular by the features of the bass mechanisms according to the invention described above. The keys can be arranged so closely that it is not possible to attach a key lever to the base plate between the keys.

[0051] Alternatively or additionally, to achieve the stated object, the invention provides the features of the independent claim directed to a method for assembling a hand-pulled instrument. In particular, to achieve the stated object, in methods of the type described above, the invention proposes that the shaft and the key lever be pre-assembled on the support or a carrier outside a base body of the hand-pulled instrument containing the bass mechanism of the hand-pulled instrument. It is also possible for other parts of the bass mechanism, in particular the entire bass mechanism, to be pre-assembled outside the base body.

[0052] The hand-pulled instrument can be a prior art hand-pulled instrument or a hand-pulled instrument according to the invention. The described method has the advantage of simplifying the assembly of such a hand-pulled instrument, since the bass mechanism does not have to be assembled and mounted inside the body of the hand-pulled instrument, as was previously the case, but is pre-assembled outside the body. This results in a modular design of the bass mechanism, which can be inserted into the body as a whole or as pre-assembled as possible.

[0053] Alternatively or additionally, the features of the subordinate claim directed to the use of a slider for coding at least one tone of a bass mechanism of a hand-operated instrument are provided according to the invention to achieve the stated object. In particular, to achieve the stated object, for uses of the type described above, the invention proposes that at least one driver be removed to establish the coding, whereby at least two different codings can be established with the slider.

[0054] The bass mechanism mentioned can be the bass mechanism already described of a hand-pulled instrument according to the invention.

[0055] The inventive use makes it possible to produce several sliders in a standardized manner for different pitch assignments, and to remove drivers only when necessary due to collisions within the bass mechanism. This can be done directly during the installation of a slider. At the same time, this allows the sliders to be reused and used for other pitch assignments.

[0056] The invention will now be described in more detail using an exemplary embodiment, but is not limited to the exemplary embodiment. Further exemplary embodiments result from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

[0058] The Figures 1 to 10show different views of a bass mechanism 2 belonging to a hand-pulled instrument 1 according to the invention, wherein different elements of the hand-pulled instrument 1 and the bass mechanism 2 are visible. Figures 1 to 10 are described in a synopsis. For reasons of clarity, not all visible elements are provided with reference symbols in all figures, where the identity of individual elements is evident from the synopsis of the figures. Thus, the identity of the Figure 3 Components shown and not provided with reference symbols, in particular from the Figures 8 to 10 .

[0059] Figure 1shows a section of a hand-pulled instrument 1 according to the invention, namely the base body 3 of the hand-pulled instrument 1 containing the bass mechanism 2. In the exemplary embodiment, this is the left bass part of a chromatic accordion, as seen from a player. The hand-pulled instrument 1 or its bass mechanism 2 comprises a series of control elements 4 in the form of buttons, by means of which a defined tone, in particular several defined tones, for example a chord, can be played. The number of control elements 4 can differ depending on the hand-pulled instrument 1. The functioning of the bass mechanism 2 is therefore explained below using a single control element 4 and its associated individual mechanism 23, which is shown in Figure 10 is shown separately.

[0060] The hand-pulled instrument 1 of the exemplary embodiment is designed as or with a convertor bass and has a switching element 28 for switching between different bass configurations, in the exemplary embodiment between a stradella bass and a melody bass configuration.

[0061] The hand-pulled instrument 1 or its bass mechanism 2, more precisely the individual mechanism 23 related to an individual operating element 4, comprises a slide 5 which can be actuated by means of an operating element 4 and has a driver 6, a shaft 7 which can be set in a rotary movement and has a shaft pin 8 which can be actuated by the driver 6, and a key lever 10 which can be actuated by a shaft hook 9 of the shaft 7 and which is designed to open and / or close at least one tone hole 11.

[0062] In particular, the Figures 7 and 9 show the tone holes 11 of the base plate 13. Figure 2shows the template 30, which also has tone holes 11 and covers some of the tone holes 11 of the base plate 13. The template is movably mounted and, depending on its position, closes various tone holes 11 of the base plate 13. Furthermore, some of the flaps 33, which are attached to flap levers 10, are labeled. Shaded areas represent examples of tone holes 37 covered by the template 30. The template 30 can be designed variably in this regard.

[0063] Each operating element 4 is connected to a respective slider 5 via a respective wire 24. The operating element 4 was manufactured or connected to the wire 24 and the slider 5 using an injection molding process. In an embodiment not shown, the operating element 4 and / or the slider 5 can be connected to the wire 24 via a plug-in, adhesive, and / or screw connection. Depending on the installation location of an operating element 4 or a slider 5, the wire 24 can be manufactured in different lengths and bent such that the operating element 4 is positioned correctly, in particular on the base body 3. The exemplary injection molding process can allow the wire 24 to be manufactured with a complete sheath.

[0064] In a longitudinal direction 25 of the bass mechanism 2, a plurality of individual mechanisms 23 are arranged next to one another, and in a vertical direction 26, a plurality of sliders 5 of individual mechanisms 23 are arranged one above the other. Only the operating elements 4 with wires 24 and sliders 5 are arranged one above the other, with the key levers 10 being arranged in one plane on the support 15. The individual mechanisms 23 each extend in the transverse direction 27. An individual mechanism 23 can be considered to be, in particular, a combination of operating element 4, wire 24, and slider 5 with driver 6 and associated shaft 7 with shaft pin 8 and shaft hook 9, as well as key lever 10, in particular with one key lever 10 being able to be controlled by a plurality of operating elements 4 or sliders 5.

[0065] For example, in the Figures 3 and 5It can be seen that the flap lever 10 is rotatably mounted in a holder 12, which is arranged at a distance from a base plate 13 containing the tone hole 11. For its mounting, the flap lever 10 comprises a cylindrical or wave-shaped extension 14, which can be mounted in the holder 12. Especially in Figure 3 It can be seen that a support 15 is arranged between the slide 5 and the tone hole 11, which rotatably supports the key lever 10. The key lever 10 is mounted in its holder 12 on the support 15.

[0066] The support 15 arranged between the slide 5 and the tone hole 11 also carries the shaft 7 rotatably, which in Figure 6 shown using the example of several adjacent shafts 7. These shafts 7 are also in Figure 3, which further shows that the support 15 is arranged between the shaft 7 and a bearing of the flap lever 10, namely the holder 12. The U-shape of the support 15 is Figure 7 removable. In Figure 11 The shafts 7, which are mounted in groups next to each other and held by respective shaft holders 29, can be seen. The shaft holders 29 can be designed to hold different numbers of shafts 7. For reasons of clarity, the shafts 7 and shaft holders 29 are not labeled continuously.

[0067] Each shaft holder 29 is identically designed and has a uniform number of shaft receptacles 31, which can be used to cover the same or different numbers of shafts 7 as required. Each shaft holder 29 has a base part 32 with which it can be fastened to a base.

[0068] Each mounted shaft holder 29 thus has five shaft receptacles 31 and can therefore hold up to five shafts 7.

[0069] It is manufactured as a standardized part, which can be adapted during assembly as required / necessary by simply removing unnecessary or disturbing shaft supports at a predetermined breaking point.

[0070] In Figure 13 Furthermore, a shaft system 34 is visible, to which two shafts 7 can be applied. Thus, for example, one of the Figure 11 The shafts 7 shown can be interrupted in the area of ​​a shaft holder 29 as required. For example, a comparatively short shaft 7 is sufficient if the control element 4 and the flap 33 to be controlled are close to one another.

[0071] Furthermore, as for example in Figure 5shown, several key levers 10 are designed identically. For a clearer illustration, the functioning of the bass mechanism 2 is shown using the example of a single key lever 10 and its associated individual mechanism 23 in the Figures 7 to 10 shown.

[0072] The shaft hook 9 acts on the flap lever 10 on a connecting lever 16 of the flap lever 10, as shown for example in the Figures 3 and 7 to 10. Here, the shaft hook 9 engages in a recess 17 of the connecting lever 16, wherein the connecting lever 16 has at least two, namely five, similar recesses 17. For reasons of clarity, the flap lever 10 is partially shown in the figures without its connecting lever 16.

[0073] The Figures 3and 7 to 10 each have a predetermined breaking point 18. The respective slider 5 is guided by means of a detachable guide element 20 which can be plugged into a guide part 19. In Figure 3 It can be seen that three sliders 5 are arranged one above the other and are guided by three guide parts 19 arranged one above the other.

[0074] In the Figures 9 and 10 It is shown that a return spring 21 acting on the flap lever 10 is arranged between the flap lever 10 and the support 15. In the illustrated embodiment, the return spring 21 is designed as a compression spring 22.

[0075] For example in Figure 3It is shown that at least one slider 5, for example the upper slider 5, has at least one driver 6, in the exemplary embodiment three drivers 6, which do not act on a shaft pin 8. The three mentioned drivers 6 of the upper slider 5 are also arranged at a distance between two adjacent shaft pins 8.

[0076] The initial example of a hand-pulled instrument 1 according to the invention shown in the figures has been assembled according to a method according to the invention for assembling a hand-pulled instrument 1. Here, the shaft 7 and the key lever 10, or in the exemplary embodiment all shafts 7 and key levers 10, are pre-assembled on the support 15 outside a base body 3 of the hand-pulled instrument 1 containing the bass mechanism 2 of the assembled hand-pulled instrument 1.

[0077] The hand-pulled instrument 1 shown and its bass mechanism 2 enable the use according to the invention of a slider 5 for coding at least one tone of the bass mechanism 2, wherein at least one driver 6 is removed to determine the coding, wherein at least two different codings can be determined with the slider 5.

[0078] In Figure 14 A single mechanism 23 of a bass mechanism 2 of a hand-pulled instrument 1 according to the invention is shown in schematic form, wherein the operating element 4 is connected directly to one of several recesses 17 of the connecting lever 16 of a key lever 10 via a wire 24. The key lever 10 is rotatably mounted on a support 15 via an extension 14 and has a key 33 with which a tone hole 11 of a base plate 13 can be closed.

[0079] The invention makes it possible to manufacture the bass mechanism 2 compactly, as is the case, for example, in Figure 15is shown. In the section of a bass mechanism 2 shown, it can be seen that the flaps 33 are arranged close to one another. This design is made possible, among other things, by the mounting of the flap levers 10 at a distance from the base plate 13. The flaps 33 can therefore be arranged closer to one another than would be possible if the flap levers 10 were mounted on the base plate 13. It can be seen that a distance 35 between the flap 33 attached to the flap lever 10 in at least one direction and a next flap 33 attached to a further flap lever 10 is smaller than an outer dimension 36 of the flap 33 in the respective direction. In this case, the direction is the direction along a largest outer edge of the approximately cuboid flap 33. In the present case, these size relationships also apply to the further direction directed at right angles to this, along the next smallest outer edge of the flap 33.

[0080] The Figures 16 to 18show a further possible embodiment of a shaft holder 29. The shaft holder 29 has an upper part 38 and a lower part 39, which can be connected to one another in a force-fitting and form-fitting manner by means of a fixing element 40. The fixing element 40 can preferably be pin-shaped. The upper part 38 can be spaced from the lower part 39 when the shaft 7 is inserted. In an embodiment not shown, the upper part 38 and the lower part 39 can also be snap-fitted, preferably to one another, and / or connected integrally to one another at at least one point and / or designed as a clamp. Furthermore, the upper part 38 and the lower part 39 each have at least one bore 41, the lower part even six bores 41, for receiving the preferably pin-shaped fixing element 40. In addition, the fixing element 40 can be connected to the lower part 39 in a force-fitting and form-fitting manner by means of a bayonet lock 42. In Figure 18It can be seen that the fixing element 40 is connected to the upper part 38 in a force-locking and form-locking manner when connected to the lower part 39 and the shaft 7 inserted into the shaft holder 29, but hidden here for better visibility.

[0081] In summary, a hand-pulled instrument 1 with a bass mechanism 2 is proposed, comprising a key lever (10) which can preferably be actuated at least indirectly by means of an operating element (4) and which is designed to open and / or close at least one tone hole (11), wherein the key lever (10) is rotatably mounted in a holder (12) which is arranged at a distance from a base plate (13) containing the tone hole (11).
