Description

Arrangement for tuning a timpani

The present invention is an arrangement for tuning a timpani resp. for tensioning / relaxing a drum of a timpani and a method for tuning a timpani.

Timpani, in particular so-called kettledrum, are tuned by tensioning or relaxing of the fur, which generally takes place by means of tension elements arranged peripherally on the edge of the fur. The coat is pulled over the tympanic rim resp. moved back again to adjust the pitch of the timpani or adjust.

Already at the beginning or In the twenties of the last century, Carl E. Gardner in US Patent 1 282 406 and Hans Schneller in Austrian Patent 87629 proposed devices for tuning a timpani. More recent proposals are further developed proposals for tuning a timpani, wherein in the two documents DE 1 266 620, and DE 30 45 576 so-called pedal systems are proposed to vote. The disadvantages of today commonly used for pedal systems are partly that, for example, the boiler is suspended in a set on 3 - 6 struts support ring. As a result, a significant sound sensitivity and attack quality of the otherwise relatively free swinging boiler edge is lost. During the tuning process to obtain a tone below the initial tone, when using natural membranes (calfskin / goatskin), the coat must first somewhat more relaxed than would be needed for the target target height, because the coat, due to the relative inertia of its elasticity (stretching and contracting), has the property to contract relatively slowly at low tension. Due to this contraction, the height of the set tone increases slightly again. This must then be jetted with a so-called fine tuner, or corrected. Due to the friction over the shoulder of the boiler resting in a fixed frame, the fur has to overcome a certain amount of external resistance. To make the contraction happen as quickly as possible, you go first to a much more relaxed level, and then, approaching from below to the target tone. A relatively complicated process.

The object of the present invention is therefore to optimize the sound characteristics of the instrument and to allow a faster and cleaner retuning.

The invention is achieved by means of an arrangement according to the wording of claim 1 or by means of a method according to the wording of claim 9.

It is suggested that the fur is not "pulled" over the edge of the rim of the boiler. is moved back, but the timpani boiler is driven against the fur or is moved away from it again.

Accordingly, it is provided that an arrangement is provided on the bottom of the vessel to move the trough or the boiler upwards against the coat and / or away from it. The natural tendency of the fur to contraction can not be avoided. Flees, resp. If, however, the boiler gives way, for example due to a pedal movement and due to the weight following gravity, under the coat, the external resistance is reduced to an insignificant minimum; the sound you are looking for can be determined more directly and is faster in.

Systems with free-swinging boiler edge and centrally up and down moving boiler are available. These are above all the rotary kiln and the hand crank system. However, these systems are not suitable for use in modern timpani literature (from the 20th century). The timpanist must be able to retune his instruments with both hands during the slide with many hands and with his feet. A pedal invention by Hans Schnellar with moving boiler (Vienna, 1920), has not enforced because of stiffness.

For this reason, the invention additionally proposes that the movement of the boiler by means of a lever member such as a lever pedal is triggered, the power transmission to the bottom of the tank but not directly but additionally translated via at least one joint or via a force reversal. The power transmission takes place, for example, via two joints in such a way that one, for example, centrally under the

Kesselboden arranged lifting rod moves the boiler up or down, the movement or the distance traveled by the boiler is substantially smaller than the movement of the lever organ. As a lever organ, for example, a foot pedal is suitable, and at the bottom of the tank, for example, a funnel-like or shell-like support is provided, in which the bottom of the tank preferably rests and on which funnel or. on which shell the lifting rod engages or engages from below.

Furthermore, a fine adjustment or "calibration" of the timpani is provided by means of which the arrangement described above can be "calibrated" for tuning to a specific pitch, in order, for example, in the event of temperature fluctuations, different air humidity, etc. to be able to compensate for any differences

Further preferred embodiments of both the arrangement and the method are characterized in the dependent claims.

The invention will now be explained in more detail by way of example and with reference to the accompanying drawings.

Showing:

Fig. 1 schematically seen from the side a timpani and the associated inventive arrangement for tuning,

2 shows schematically enlarged the inventive arrangement,

Fig. 3 is a schematic sectional view of a section of an arrangement according to the invention, showing in particular a fine adjustment for calibrating the timpani to a specific pitch, Fig. 4 shows the arrangement from FIG. 3 schematically in lateral perspective,

Fig. 5 on average the lifting unit of the fine adjustment of FIGS. 3 and 4, and FIG. 6 in perspective a timpani with special appreciation of the fine tuning resp. Calibration of the timpani.

Figure 1 shows schematically seen from the side a timpani boiler 1 and a fur 3, which is clamped by means of lateral support members 5 which are fixed to a base plate 7, fixed over the edge of the boiler 2. These lateral holding elements 5 can be shortened or screwed, for example by means of screw threads. be extended to allow the tensioning of the fur 3 on the kettledrum 1. For the tuning of the fur, an arrangement is now provided below the timpani boiler 1, by means of which the boiler moves against the fur 3 or. can be moved away from this. When raising the tympani, the fur 3 is additionally tensioned, which causes an increase of the sound, during which, when lowering the tympani, the fur relaxes a little and accordingly a deeper tone is produced. The lifting of the boiler by means of a pedal lever 9, terminal having a footrest 11, wherein the lever, for example, guided by means of a guide 8, shown in two different positions. In position 9 is the

Timpani boiler in the lowered state, during which in the position 9 'of the boiler 1 in the raised state, with a correspondingly more tense fur 3. The foot lever 9 is opposite to the footrest 11 in an axis 15 at a holding body 13 is mounted and upon actuation of the foot lever 9, the force is transmitted via a sliding or rolling surface 16 and a ball bearing 18 to a further reversing lever or rocker 17. The reversing lever resp. the rocker 17 is about an axis 19 at a

Mounting body 21 mounted and in turn at the opposite end via a ball bearing 23 with a lifting or. Lowering rod 25 in contact, which in a base support frame or. Housing 26 with lateral opening 24 held movable in the vertical direction or. is arranged. This lifting or lowering rod 25 is in turn connected to a funnel or a shell 27, which on the tank bottom 1 or on. engages and which shell is formed such that the boiler preferably fits snugly against the inner wall of the shell or the funnel.

For the movement process, that is, for the raising or lowering of the boiler, reference is made to Figure 2, in which the lifting or. Senkanordnung is shown in detail schematically.

Again, the foot lever 9 is shown in two positions, namely in a raised position with lowered tympanum boiler (the latter not fully shown) and in lowered position 9 ', with raised timpani boiler with a correspondingly more taut drum taut. The lever 9 or 9 'is mounted about the axis 15 in the fastening body 13. About a rolling or sliding surface 16 and. 16 ', which via a ball bearing 18 or 18' with the reversing lever or. the rocker 17 resp. 17 'rolling _ -j_

or sliding in contact, the power is transmitted to the lifting or. Lowering rod 25. The universal lever resp. the rocker 17 or 17 'is in turn mounted or held in an axis 19 in a further fastening body 21. In this case, the position of the drawn reversing lever or. the rocker 17 analogous to the position of the foot lever 9 and the position of the rocker 17 'according to the position of the foot lever 9'. In agreement, the position of the ball bearing 23 and. 23 ', via which bearing the reversing lever or the rocker with the Hubbzw. Lowering rod 25 is in contact. Finally, in an analogous manner, the position of the shell or of the funnel 27 or. 27 'drawn. It is clearly recognizable now that at the position of the foot lever 9 the funnel or. the shell 27 is lowered while in the

Position of the foot lever 9 ', the shell or the hopper in the raised position 27' is.

It goes without saying that between the two positions of the foot lever shown in FIG. 2, any desired intermediate positions are possible to produce a specific pitch. The movement of the foot lever from the position 9 to position 9 'is infinitely possible or rasterized in fine intermediate steps, resulting for example by intervention in the guide 8. Furthermore, it is also possible to provide a scale by means of which the respectively necessary position can be set in order to produce a specific pitch on the drum skin. Furthermore, a fine adjustment 22 is provided on the fastening body 21, by means of which the axis of rotation 19 of the reversing lever or of the rocker 17 or respectively. 17 'changed resp. can be adjusted. This is necessary if the basic pitch of the timpani as a result of temperature fluctuations or. is to adjust for different air humidity. This AusJustierung takes place, for example, during the insertion of an orchestra and can also be changed during the rehearsals and the concert if necessary. This is the basic setting, so to speak a "calibration" of the timpani.The adjustment of the basic setting or the correction of the pitch must also be possible during the rehearsal or the concert, because then just, for example by the breath many people who can greatly change humidity.

With reference to Figures 3 to 6 described below, such an arrangement for Adj ustieren or to oak of a timpani will be described in detail. FIG. 3 is a schematic sectional view of the region of the arrangement according to the invention, in which this additional arrangement is arranged for dressing or oaking. Again, the tuning of the timpani takes place primarily by means of the foot lever 9, which is mounted end-to-end in an axis 15 on the holding body 13. About a sliding or

Rolling surface 16, the power is transmitted to the rocker 17, wherein now in the example according to Figure 3, not a ball bearing 18 is provided, but a correspondingly formed on the rocker sliding surface 20. By means of an additionally provided knob 14 is another

Setting possibility of the position of the foot lever 9 given. About the rocker 17, which is mounted in the axis 19, via the ball bearing 23 and the lifting or lowering rod 25, the movement of the boiler. Instead of the pure fastening body 21, as shown in Figure 1, is now an additional arrangement 22 is provided for adjusting or adjusting. Oaks of the basic pitch of the timpani. This takes place by means of a precision spindle 36 which is provided centrally in the additional arrangement 22 and which is driven upwards via a ball bearing by means of a toothed disk 38. can be moved down. The toothed disc 38 in turn is driven by means of a movement belt 45. Is stored this additional arrangement, as, by the way, for example, the holding body 13, on a base plate 51st

In Figure 4, the section of Figure 3 is shown in perspective from the side, now clearly the drive belt 45 can be seen, which is used for driving the toothed wheel 38. The drive belt 45 extends over guide rollers 47 in an actuating housing 49, at the top cover a square drive 50 is provided.

In Figure 5, the Feinadjustiermechanismus is shown in section. In a Hubeinheitgehäuse 31 of the adjustment, which is fixedly fixed to the base plate 51, a deep groove ball bearing 32 is provided, which is fixedly connected with its except part 32 'with the housing 31. The toothed disc 38 is fixedly connected to an intermediate flange 33, the inner part 32 '' of the groove ball bearing 32 and with a flange single nut 35 and forms together with them a rotary unit. Through the flange nut 35 runs a threaded spindle 36. The spindle can be moved by turning the pulley unit 38, depending on the rotation in the vertical direction up or down. The way up, for example, limited a disc 37, with a Countersunk screw 40 is attached to the lower side of the spindle 36. Down the movement is limited by the mounted on the spindle rotating and bearing block of the small lever. A recessed space in the base plate 51 under the spindle allows the spindle to be lowered below the surface of the base plate, allowing a total stroke of, for example, 30 minutes. Finally, the toothed pulley unit 38 is driven by the drive belt 45, as shown in particular in FIG. 4. Finally, in FIG. 6, an entire perspective is shown

Timpani presented, with special appreciation of the additional Adjustier- or. Calibration unit. In particular, the drive belt 45, which is arranged by turning the square drive 50 at the upper end of the drive housing 49, can be driven or driven. is movable. Thus, for example, it is possible via a rotary rod or spindle 63, which is arranged in a holder housing 61 and which has a knob at its upper end to rotate the square attachment 50 in one or the other direction. As a result, it is now possible to tune the timpani to a specific fundamental tone by moving the drive belt 45 and via the additional fineadjustment device. to calibrate the timpani. This is particularly important for a scale arranged on the foot pedal, for example, indicating the pitch of the timpani to have a correct indication even in the event of changed ambient conditions, such as temperature and humidity, ie. H . that, for example, changes in the scale occurring during temperature fluctuations by means of the additional Fineadj ustierung can be compensated or corrected.

In the examples of an arrangement according to the invention shown in FIGS. 1 to 6 for tuning a timpani as well as an additional arrangement for oak and / or wood.

Of course, fine particles are only examples to further explain the basic idea of the present invention. It is essential that the power transmission is not directly, d. H. without intermediate joints and / or translations, which has proven impractical in the past. It is essential that at least one reversal of the force takes place or a force amplification or a force transmission, in order to move the lever organ as the foot lever tambourine towards fur or. to move from the fur. How this translation is done and whether there are two, three or multiple redirections of power is more of a minor importance and, ultimately, a matter of requirements. Depending on how finely adjustable the pitch must be when tuning, is accordingly the

Transfer of power from the foot pedal to the timpani boiler.

Furthermore, it has also been found that various materials are suitable for the production of the arrangement such as the foot pedals, the lifting or. of

Senkzylinders as well as the funnel or. the Bowl . For example, water - cut steel or anodized aluminum are suitable for all parts except the hopper and / or. the shell, which is preferably made of copper are made. Also, the aluminum, before it is anodized, preferably with Wasserj et cut. It has also been found that brass is preferred for any base arranged below the funnel or the shell, on which the lever or the lifting rod engages. The lifting resp. Lowering rod is preferably made of tempered surface hardened steel and preferably runs in a Kugelbüchselagerung. All bearings are preferably maintenance-free form so that no tools such as lubricating oils and the like are necessary.
