Abstract

A hi-hat (1) is used as an instrument, especially as a percussion instrument. The inventive hi-hat consists of a set of in total three or more cymbals (2, 3, 4). An upper mobile cymbal (2) and a lower, also mobile cymbal (4) are struck against the middle, stationary cymbal (4) by means of a common operating device (5), in order to produce a noise. The movement of the pedal (31) is reversed by means of either an appropriate pneumatic arrangement with a piston (8) and corresponding cylinder chambers (10, 23) or a mechanical device which diverts the pedal movement via a cable (50) and a deflection pulley (51) so that the outer tube (14) moves upwards against the middle cymbal (3) whilst the rod (7) is pulled downwards in the opposite direction, hereby causing the upper cymbal (2) to strike the middle cymbal (3).

Description

Triple hi-hat with simple controls

Description

The invention relates to a hi-hat for producing sounds by mutually bringing together cymbal plates, of which one cymbal plate is connected to a fixed tube, while another cymbal plate can be actuated by an operating device and is assigned to a rod that can be moved up and down.

In addition to various types of drums and timpani, convex-shaped cymbal plates, so-called cymbals, are used as rhythm and percussion instruments when making music. Single or multiple cymbals can be used as a percussion instrument, with sounds being generated by means of sticks or adequate aids. Likewise, cymbals can also be struck against each other, with two cymbals of the same size touching on their outer edges. Such a blow causes the cymbals, which are preferably made of metal, to vibrate, which produces a particularly sustainable sound. The standard equipment of a drum kit also includes so-called hi-hats. An essential part of this instrument are two cymbals, which, controlled by a pedal, are brought together to produce a sound in such a way that - as described - they meet with their edges. As a rule, the upper cymbal plate is movable, the lower one rigidly arranged. By actuating the pedal, a rod which is resiliently mounted at its lower end and is located in a tube is pulled down, at the upper end of which the upper cymbal plate is fastened. This strikes a cymbal plate connected to the pipe and facing it. This creates the typical metallic and long-lasting sound. In concerts, such as recordings in the studio, hi-hats are used as rhythm instruments, which can usually be operated in time by the drummer's footwork. The bass drum is usually operated with the other foot. The problem thus arises that with a single operating device, usually a pedal, only a simple beating together of a maximum of two baskets can be carried out. The footwork of a drummer is usually limited to operating a bass drum with one foot and beating two cymbals together to create a sound with the other. At best, variations are possible by using cymbals of different sizes that trigger different sounds. In the course of concerts, it is at best conceivable to use several of these hi-hats, played by several people, at the same time in order to achieve more intense or fuller sounds. Also certain effects, such as B. two offset sounds, can not be realized with the help of the currently known versions of the instruments. In the context of studio recordings, it is possible by means of complex modern technology to achieve this goal of a fuller or offset sound through multi-track recordings. However, this is associated with high technical and time expenditure and cannot be realized at all in live concerts.

The invention is therefore based on the object of providing an instrument which ensures an increase in the variety of sounds with variable setting options.

This object is achieved in that the cymbal plates are assigned at least one additional cymbal plate that can be moved up and down, which can be actuated via the control device with the movable cymbal plate or separately from it and guided against the fixed cymbal plate and / or against the other cymbal plate and is posted.

Such a hi-hat can also be referred to as a triple hi-hat, because at least three cymbal plates are available which are to be guided and struck against the central cymbal plate or against one another. This results in an enormous variety of additional sounds that cannot be achieved with previous hi-hats. This results in a significant increase in the play options, some of the settings described further below being used as operating devices build on the known devices that have been used to move the upper cymbal plate against the fixed cymbal plate. However, other solutions are also possible, whereby, among other things, it is intended to operate or Use the operating device by moving the two movable cymbal plates by hand against the fixed cymbal plate. However, such an operating device is generally no longer sufficient for today's requirements, so that it is expedient to fall back on the pneumatic or mechanical operating devices described further below.

According to an expedient design, it is provided that the further cymbal plate arranged under the fixed cymbal plate is assigned to an outer tube which envelops the fixed tube and is displaceable via the operating device. What is achieved via the operating device is that the upper cymbal plate is guided downwards against the middle cymbal with the same operating device and at the same time the lower cymbal plate is raised and struck against the middle cymbal plate. This requires the direction of movement of the rod moving the upper cymbal plate. Details of this are explained further below.

A particularly expedient design of a mechanical operating device for the triple hi-hat described is that in which the rod is connected in an articulated manner to a pedal known per se, which at the same time is designed to act on a cable connected to the outer tube, the cable being provided via a deflection roller guided on the outer tube is fixed. As already mentioned further above, with such an operating device it is possible to move the upper cymbal plate downwards against the middle cymbal plate and at the same time move the lower cymbal plate upwards against the middle cymbal plate. It can be ensured by the operating device that all three cymbal plates meet at the same time or with a certain time delay, depending on which player wants it to be. It is important that he moves the rod downwards with one and the same pedal movement, as well as simultaneously moves the outer tube upwards via the cable and the deflection roller. So he only needs a single pedal to operate both movable cymbal plates, so that he can use the other foot can either operate another instrument or just keep calm.

The rod moved up and down and the correspondingly moved cable can be moved in one and the same "foot" of the hi-hat, because according to the invention it is provided that the rod is formed in several parts and consists of pedal part, sleeve part and plate rod, whereby the pedal part is designed as a tube receiving the cable in the direction of the deflecting roller and the adjoining sleeve part is designed as an intermediate linkage comprising the deflecting roller and connected to the plate rod. In the actual sense, a continuous rod is no longer used, but such a mechanism that also ensures the movement of the cable and its deflection via the deflection pulley, so that the downward movement of the rod can be changed into an upward movement of the outer tube.

In order on the one hand to enable a uniform upward movement of the further cymbal plate and on the other hand to ensure a uniform return to the starting position, it is provided that the foot of the outer tube carrying the further cymbal plate is guided in a cylindrical tube surrounding the fixed tube and at the end an outwardly projecting collar has, which is mounted between two cylindrical springs arranged in the cylinder barrel. It goes without saying that the two cylindrical springs must be supported upwards and downwards in the cylinder tube, which is why the cylinder tube is provided with a cover on both sides. The two cylindrical springs are designed in such a way that a uniform raising and lowering of the cymbal plate or the outer tube carrying it is ensured.

The cable lies inside the correspondingly hollow rod or pedal part. Accordingly, its movement must be transmitted through the surrounding parts to the outer tube. For this purpose, it is provided that the cable connected to the pedal is fixed at the other end via a cam cylinder on the outer tube, the connecting cams of which are designed to penetrate a slot in the stationary tube. This ensures that the outer tube is securely guided during its upward and downward movement and is also guided against twisting, because the connecting cam protrudes through the slot and exactly maintains its position when moving up and down.

The distance between the further cymbal plate and the fixed cymbal plate can advantageously be varied in that the outer tube is a telescopic tube, the end piece of which is assigned to the cymbal plate and is designed to change the distance between the cymbal plate and another cymbal plate and is equipped with a corresponding clamp. The outer tube is thus in the upper area, i.e. H. in the area of the end piece in two parts, the two parts being slidable into one another and connected via the clamp in such a way that they each act as a tube to lift the further cymbal plate and guide it safely.

Likewise, the distance between the fixed cymbal plate can also be varied, because according to the invention it is provided that the fixed tube with the cymbal plate is designed to be continuously telescopic at the end. Here too, suitable additives, for example a corresponding clamping device, ensure that the two parts of the fixed tube can be moved into one another and can be fixed to one another.

The pressure generated by the cylindrical springs on the outer tube, which can be pushed up and down, can also be changed because, according to the invention, the cylindrical tube receiving the cylindrical springs is connected to a bottom ring by means of a thread and thus the springs are designed to be clamped. Depending on how far the cylinder tube is "pushed" past the thread on the bottom ring, the pressure increases and the forces required to move the outer tube must be correspondingly high. As a rule, however, these springs are dimensioned so that only a swinging back and an accurate guidance of the outer tube is ensured.

According to the invention, it is also provided that the movement of the further cymbal plate can also be changed, for example with regard to the fact that it moves in the same direction as the upper cymbal plate. The invention achieves this in that the pedal part of the rod is designed so that it can be coupled directly to the outer tube via a cam drive plate. This redirects the movement tion of the pedal switched off, since the rod and the outer tube are connected to each other, so that the same direction of movement must be observed. It may be necessary to make the cable pull so elastic that there is no over-tensioning and tearing.

The overvoltage and the demolition are prevented in particular by assigning a spring arrangement to the cable, the hardness of which is higher than that of the cylindrical springs. This ensures that when the outer tube moves against the pressure of the cylindrical springs, the spring arrangement leads to an elongation of the cable, so that damage is avoided here. The length and design of the spring arrangement can be adapted to the particular circumstances, it being necessary to give the cable pull a certain flexibility by the spring arrangement, which prevents tearing.

Another embodiment of the present invention than the mechanical described above is the pneumatic configuration described below, in which the deflection of the downward or upward movement of the rod with respect to the outer tube is achieved pneumatically. For this purpose, according to the invention it is provided that the rod is assigned a piston, the fixed tube serving as a cylinder housing with an upper and a lower cylinder chamber. Since with the pedal the rod running inside the fixed tube is moved downwards with the pedal, but the outer tube with the attached lower cymbal plate has to be moved upwards in order to guide it against the rigid cymbal plate, a deflection is necessary that first the piston arranged in the cylinder housing is moved downwards while the pedal is actuated, thereby producing a pressure cushion. This pressure cushion is pressed through the outlets into a so-called air chamber. This air cushion can only look for this one way, since the bottom of the cylinder housing is on the underside. The resulting pressure rises at great speed, so that the outer tube with the lower cymbal plate connected to it pushes upwards until it hits the middle, rigid cymbal plate. Instead of this air cushion, it is also conceivable to work with liquids. It is advantageous that the lower cylinder chamber located below the piston is sealed from the atmosphere and via an outlet has a connection to a lower air chamber formed between the outer wall of the fixed tube and the displaceable outer tube, its outlet connecting to the lower one Manufactures air chamber. Moving an air cushion into an adjacent chamber is of course only possible if it is sufficiently sealed against the other chambers and the outside air. This is the only way to ensure that the air really looks for the intended way to achieve the desired effect, in this case pushing up and then lowering the outer tube. Any connections to the outside air would prevent this, since the air would seek the path of least resistance through these openings.

So that the outer tube, triggered by the actuation of the pedal, pushes upward, it is further provided that a surface is created on which the air cushion engages and thus pushes the outer tube upward. This is ensured by the fact that the outer tube is assigned an annular piston that delimits the air chamber. This ring piston is located on the inner wall of the outer tube, with which it is non-positively connected. The ring piston can be turned off during the manufacture of the outer tube, but it can also be welded, screwed on or connected to the outer tube in some other way. It ensures that the outer tube is raised as described when the upper cymbal plate is pulled down.

It is provided according to the invention that the upper cylinder chamber is connected to the atmosphere via openings. When the piston is moved downward, air flows in through the openings into the upper cylinder chamber. If this were not the case, the piston could only be moved downwards with enormous forces. With the hi-hat according to the invention, however, the aim is of course to be able to operate this instrument, which essentially consists of three cymbal plates, as easily as an instrument consisting of two cymbal plates. After releasing the pedal, the entire body must return to its starting position, in particular the piston must move up again. This is also only possible because the inventive Openings from the cylinder chamber to the atmosphere are provided and the piston can push the air in the upper cylinder chamber outward with practically no resistance.

The air is thus pushed out of the lower cylinder chamber into the lower air chamber, the outer tube evades this pressure by evading upwards. The air in the upper air chamber, on the other hand, cannot escape and is compressed, which results in an intended spring effect.

This can be varied in that the annular piston divides the cavity between the fixed tube and the displaceable outer tube into the lower and an upper - each sealed - air chamber, a valve being arranged in the outer wall of the upper air chamber, so that a predetermined air cushion is retained by the valve is designed to open and set when a certain pressure is reached. After releasing the pedal, the air in the air chamber tends to expand again and consequently pushes the ring piston down again, the air in the lower air chamber is pushed back through the openings into the lower cylinder chamber. The instrument can thus return to its starting position.

Furthermore, it is provided that the lower cymbal plate and the outer tube are designed to cause the outer tube to sink into the starting position when the operating device is actuated or released. The dead weight of the bowl plate and the outer tube alone or in combination with the described air effect causes the system to reset. In any case, this guarantees that when you release the pedal, you return to the starting position and the pedal can be pressed again. This is an absolute prerequisite for the use of this instrument, particularly as a result of the high loads that are exerted when using this instrument when making music.

As described, it is important that the upper and lower air chambers are sealed off from each other, as the air in the upper is to be compressed, while the pressure in the lower one is used so that the ring piston and thus the outer tube with the lower bowl plate move upwards. For this reason, an annular groove with an O-ring is provided in the area of the annular piston in the outer wall of the fixed tube. This combination of ring groove and O-ring ensures that both chambers are reliably sealed against each other even when the ring piston is moved.

A preferred embodiment provides that a valve that maintains a predetermined air cushion in the air chamber is arranged in the outer wall of the lower air chamber. The valve is expediently designed to open and set when a certain pressure is reached. With such a valve, the air cushion can be varied so that the distances to be covered when the pedal is actuated are shorter or longer. If there is already an air cushion with high pressure in a chamber, the path that the pedal has to travel until the outer tube moves so high that the lower cymbal plate hits the middle one is relatively short. If, on the other hand, an air cushion has to be built up by pushing a lot of air from the cylinder into the air chamber, the distance is correspondingly longer. Thus, a valve can be used to set when the lower cymbal plate hits the middle cymbal plate in relation to the upper one. The lower one can hit the middle, rigid cymbal plate at the same time, before or after the upper one. This allows acoustic effects to be achieved that were previously not possible without the aid of modern sound technology. Such offset strokes are popular variations when playing the drums. By adjusting the valves, it can also be controlled that the lower cymbal plate not only hits the middle one briefly, but also remains in this position for a moment. As a result, both cymbal plates cannot swing freely, which in turn leads to a modified, duller sound. Here is another advantageous setting option. When the valves are opened, on the other hand, the air displaced from the cylinder chamber flows into the outside air through the open valve instead of pushing the outer tube upwards. The lower cymbal plate is not working. The triple hi-hat only looks like a conventional one.

It also proves to be advantageous if the valves are designed as a changeover valve. forms are. Such valves react in two directions, i.e. outwards and inwards and can thus be set to the most varied of conditions.

In order to achieve optimum swingability of the cymbal plate, in particular the middle cymbal plate, which is struck by both the upper and lower cymbal plates, it is provided that the central cymbal plate is designed to be wave-shaped in its radial direction. This shape - the number, shape and extent of the waves is arbitrary - ensures that the middle cymbal plate can still vibrate to a considerable extent even if the upper and lower cymbal plates are struck together, which is absolutely desirable in terms of the quality of the sound . This effect is due to the more compliant and less rigid structure of the cymbal, but also due to its enlarged surface. By replacing the middle cymbal plate, the drummer can realize "his" ideal sound.

So while the middle cymbal plate is shaped in such a way that it can be optimally struck from above and below, it is provided that the upper cymbal plate and the lower cymbal plate are convex and are each arranged with the curvature facing outwards in order to produce ideal vibration behavior and to realize a corresponding sound image.

A hi-hat is exposed to constant and large loads, so that high quality of the connections of the individual components of this instrument is of great importance. In particular, it is provided that the rod is detachably connected to the upper cymbal plate. This frictional connection takes place via tensioning devices known per se, mostly made of metal or plastic, in a preferred embodiment the tensioning devices can be adjusted so that with looser clamping a good oscillation with a reverberant sound and with firm clamping a reduced oscillation with a duller sound is effected. In addition, the function of the cymbal plate can be specifically changed or stopped by detaching it from the rod. It serves the same purpose that the outer tube is detachably connected to the lower cymbal plate in a preferred embodiment. Changes in the function and also in the sound behavior can thus be implemented in a simple manner.

To generate the described air cushion and movement of the outer tube etc., it is provided that the rod below the piston in the area below the lower cylinder chamber through an annular groove with a sealing ring and above the piston and above the upper cylinder chamber through an annular groove with a sealing ring in relation to the cylinder housing as well the piston is sealed off from the inner wall of the fixed tube by an annular groove with a sealing ring.

Such a sealing system is provided below the lower cylinder chamber in order to seal it off from the environment for the reasons mentioned. This prevents air from the lower cylinder chamber, which is triggered by the downward movement of the piston, from being pushed through the openings into the lower air chamber as intended, but rather out of the chamber system.

The same applies to the area above the upper cylinder chamber, where an annular groove with a sealing ring is also arranged, this time as the end of the upper cylinder chamber.

To optimize the flow between the lower cylinder chamber and the lower air chamber, it is recommended that several outlets to the lower air chamber are provided distributed over the circumference of the cylinder housing. It is essential that the air can be displaced from one chamber to the other at very high speed. For this reason, the area through which the air can find its way should be as large as possible. In the ideal case, the fixed tube is only formed continuously in the area of the openings at the points that are structurally necessary.

To avoid wear and avoid additional connections, It is envisaged that the rod and piston are one component.

The invention is characterized in particular by the fact that a musical instrument or a hi-hat is created which is very versatile and gives the musician the possibility of realizing different sound variations, without the need for additional equipment. Rather, the hi-hat has been expanded to a triple hi-hat, although it is also conceivable to provide additional cymbal plates in order to specifically increase the possible variations. It is particularly advantageous that the musician is given the opportunity to work with one and the same musical instrument with which three cymbal plates or more are actuated at the same time, or else with the two cymbal plates that may only be used as previously. For this purpose, only the corresponding connection, which provides the direction of movement of the lower additional cymbal plate, needs to be released, so that then only the upper cymbal plate is moved towards the fixed cymbal plate as before and struck against it. As a rule, however, the solution according to the invention can be seen in the use of the three cymbal plates, one of which is moved from top to bottom and the other from bottom to top against the respective central cymbal plate. Since only one pedal is used, the effort for the musician does not increase at all and he can change the sounds or adjust them in such a way that a corresponding sound sequence is achieved. The variety of possibilities described naturally appeals particularly to musicians who are keen to experiment, although there are other possibilities for influencing them with the truncheons.

Further details and advantages of the subject matter of the invention emerge from the following description of the associated drawing, in which a preferred exemplary embodiment is shown with the necessary details and individual parts. Show it:

Fig. 9 is an enlarged representation of the "pneumatic" receiving parts.

Figures 1 and 2 show a hi-hat 1, which is actually to be referred to as a triple hi-hat, because in addition to the known upper movable cymbal plate 2 and the fixed cymbal plate 3, another cymbal plate 4 is provided, which is operated with the help of the operating device 5 up and down and thus can be moved against the fixed platter 3.

The fixed cymbal plate 3 is arranged at the upper end of the fixed tube 6, which is a conventional cymbal plate, which can be struck both from above and from below.

It can be seen from FIGS. 1, 2 and 3 that cymbal plates 2, 3, 4 are used which have a different diameter. In particular, it is provided that the lower cymbal plate, i. H. that is, the further cymbal plate 4 has the largest diameter.

The upper cymbal plate 2 is connected to the rod 7, which can be moved up and down. bound, this rod 7 is detachably connected to the upper cymbal plate 2. A corresponding screw clamp 48 can be seen.

With the aid of the mechanical operating device 5 explained in FIGS. 1 to 7, the upper cymbal plate 2 is moved and struck against the fixed cymbal plate 3, while the further cymbal plate 4 is moved from below against the fixed cymbal plate 3. It will be explained further below that there is also the possibility of moving both movable cymbal plates 2, 4 in the same direction.

The standpipe 49, which carries the cymbal plates 2, 3 and 4, consists of various tubes which are guided one inside the other. H. of the rod 7, which is of tubular design here, a cable pull 50 is guided over a deflection roller 51 such that when the pedals 31 are moved downward, the outer pipe 14 connected to the cable pull 50 is moved upward against the pressure of the spring 33. At the same time, the rod 7 is moved downward as usual, so that the associated upper cymbal plate 2 hits the fixed cymbal plate 3.

To receive the cable 50 and also the deflection roller 51, the rod 7 is divided into a hollow pedal part 52, a correspondingly hollow sleeve part 53 and a plate rod 54, which are each connected to one another. Further details can be found in particular in FIGS. 5, 6 and 7. It can be seen here that the cable pull 50 can move centrally within the pedal part 52, although the cable pull 50 is connected at the other end 62 to the cam cylinder 63 and thus to the outer tube 14. The cam cylinder 63 has connecting cams 64 which extend through the fixed tube 6 and also through the pedal part 52. For this purpose, these are provided with a slot 65.

In the area of the foot 55 of the outer tube 14, this is provided with a collar 58, this collar 58 being supported between two cylindrical springs 59 and 60. These cylindrical springs 59, 60 are mounted in a cylinder tube 57, which is closed at the top and bottom, so that the cylindrical springs 59, 60 are can support against. So that the foot 55 of the outer tube 14 is guided evenly, regardless of whether the outer tube 14 is moved up or down. The corresponding cylindrical springs 59, 60 ensure the necessary uniform guidance in both directions and also ensure that the collar 58 and thus the outer tube 14 swings back into the starting position when the foot is removed from the pedal 31.

The cylindrical springs 59, 60 can be preloaded in that the closure of the cylinder tube 57 is formed at the bottom by a bottom ring 69 with a thread 70. The cylinder tube 57 can thus be moved more or less far over this base ring 69 so as to adjust the preload of the cylindrical springs 59, 60 according to the respective requirements.

It has already been pointed out earlier that the upper cymbal plate 2 is detachably connected to the rod 7 or the plate rod 54 via the screw clamp 48. In addition, this screw clamp 48 also gives the possibility of changing the distance between the upper cymbal plate 2 and the fixed cymbal plate 3.

The distance between the lower cymbal plate 4 and the central cymbal plate 3, which is arranged in a fixed manner, can be adjusted by making the end piece 67 of the outer tube 14 telescopic. The two ends of the outer tube 14 are effectively fixed to one another via the clamp 68, so that the position or the height of the further cymbal plate 4 can be varied accordingly.

Not only the upper cymbal plate 2 and the further cymbal plate 4 can be changed in their position, but also the middle, fixed cymbal plate 3. For this purpose, the telescopic clamp 75 is provided, which connects the two parts of the fixed and mutually displaceable tube 6, depending on how far the inner fixed tube 6 has been pulled out of the other tube. This is particularly shown in FIG. 4. FIG. 4 further clarifies that the deflection roller 51 is rotatably mounted in the fixed tube 6 via the axis 74. This ensures that the cable pull 50 is correctly rerouted, even if the cable pull 50 has to be moved against the force of the cylindrical spring 59 or, if applicable, also 60.

The peculiarity of the cymbal plates 2, 3, 4 has already been pointed out above. Figure 3 in particular illustrates the special shape, although this is not decisive for the design of the hi-hat described here. Further versions, for example that according to FIG. 8, are also conceivable.

In the arrangement shown in FIGS. 5, 6 and 7, the further cymbal plate 4 moves downward onto the fixed cymbal plate 3 and the upper cymbal plate 2 also downwards onto the fixed cymbal plate 3. Now the further cymbal plate 4 should move in the same direction as the upper one Cymbal plate 2 are moved, so it is possible to lay it on the fixed cymbal plate 3 by loosening the clamp 68 and then via the cam follower plate 71 and the other parts necessary for this purpose directly to the outer tube 14 with the rod 7 or with the cable 50 connect. It is thereby achieved that both the further cymbal plate 4 and the upper cymbal plate 2 are moved downwards when the pedal 31 is moved or pressed down. In order to avoid excessive strain on the cable pull 50, a spring arrangement 72 is provided, the hardness of this spring arrangement 72 being significantly higher than that of the cylindrical springs 59, 60. This ensures that this spring arrangement 72 really only prevents the cable 50 from being overstressed.

FIG. 8 also shows a complete arrangement of a hi-hat 1. This hi-hat 1 is operated via the control device 5, usually the pedal 31.

Figure 1 shows the complete arrangement of a triple hi-hat. The instrument 1 is operated via an operating device 5, usually a pedal 31. With this, the upper cymbal plate 2 is moved downwards and the lower cymbal plate 4 upwards, optionally together or separately. The pedal 31 is non-positive connected to the rod 7, which is associated with a return spring 33 at its lower end. This return spring 33 is compressed when the pedal 31 is actuated in order to relax again when the pedal 31 is released. As a result, the rod 7 returns to its starting position and can now be pulled down again when the pedal is actuated again. The rod 7 is surrounded by a fixed tube 6, with which a rigid bowl plate 3 is connected. When the pedal 31 is depressed, the movable upper cymbal plate 2 strikes the rigid middle 3, whereby the desired sound effect is achieved. The cymbal plates 2, 3 are shaped in such a way that they only strike each other at their outer edge and have a curvature 25, 25 'in order to ensure the best possible swinging of the cymbal plates 2, 3.

In the previously known technique, the second, that is, the lower cymbal plate was convexly curved like the upper one. This is no longer the case with the triple hi-hat now presented, since an upper cymbal plate 2 and a lower cymbal plate 4 strike against the middle cymbal plate 3. This changed requirement, namely that the middle cymbal 3 must ensure optimal swinging in both directions, is met by the corrugated shape of the central cymbal 3. Other embodiments are also conceivable, such as. B. a flat, a slightly convex or even a conventional convex bowl plate. A hole is provided in the middle of all three cymbal plates 2, 3, 4. Around this hole is a circular surface which is shaped so that fasteners 34, 35, 36 can be attached. The fastener 34 establishes the connection between the upper cymbal plate 2 and the rod 7, the fastener 35 between the central cymbal plate 3 and the fixed tube 6 and the fastener 36 between the cladding tube 16 and the lower cymbal plate 4. These fasteners 34, 35, 36 are preferred molded from metal or plastic and, if possible, fixable with bracing. By this fixation only in the middle of the cymbal plates 2, 3, 4, the smallest possible area of the cymbal plates 2, 3, 4 is to be braced because, on the other hand, the largest possible area of the cymbal plate body should vibrate freely.

In addition to the upper cymbal plate 2, when the pedal 31 is actuated, the lower cymbal plate 4, if this is set, guided against the central cymbal plate 3, which triggers an additional sound. This sound can sound in addition to or at different times to that triggered by the upper cymbal plate 2.

The exact functioning of the lower cymbal plate 4 can be seen in FIG. 2. If the pedal 31 is depressed, the rod 7 lowers with the piston 8 assigned to it. This is surrounded by an upper cylinder chamber 10 and a lower cylinder chamber 23, the stationary tube 6 surrounding the piston 8 forming the cylinder housing 13. The fixed tube 6 also forms the closure for the cylinder chambers 10, 23 upwards and downwards. In the embodiment selected here, the piston 8 and the rod 7 are a component, which is particularly recommended due to the high dynamic loads on the entire instrument 1.

In the embodiment shown in Figure 2, the system is in a starting position. When the rod 7 moves downward, triggered by the pedal 31 being depressed, the piston 8, which is sealed by means of the annular groove 42 and the O-ring 43, is moved down. The air located in the lower cylinder chamber 23 is pressed by the piston 8 through the outlet 9 into the lower air chamber 11 formed between the outer wall 15 of the fixed tube 6 and the displaceable outer tube 14. These outlets 9 are distributed several times over the circumference of the cylinder housing 13, because they serve as a through-flow space and are intended to ensure a good connection between the lower cylinder chamber 23 and the lower air chamber 11.

In order to ensure that the lower cymbal plate 4 can strike the central cymbal plate 3, the outer tube 14, to which the lower cymbal plate 4 is attached, is slidably mounted. The air pressed out of the lower cylinder chamber 23 pushes this outer tube 14 upwards. A prerequisite for this movement is a sufficiently large annular surface 21 of the annular piston 20 as a possible means of attacking the air. A deflection of the force is thus achieved by this arrangement, because the pulling down of the rod 7 with the piston 8 causes an upward movement of the outer tube 14, which ultimately leads to the lower cymbal plate 4 being pressed against the middle leren cymbal plate 3 beats. To avoid negative pressure, an opening 26 is provided in the inner wall 17 of the upper cylinder chamber 10, which creates a connection to the atmosphere. When piston 8 moves downward, air is drawn into the upper cylinder chamber 10 from the outside. The already mentioned annular surface 21 forms the lower end of the annular piston 20, which is non-positively connected to the outer tube 14. Here, too, it is advisable to manufacture the outer tube 14 and the annular piston 20 from the same component due to the high dynamic loads. The annular piston 20 can, however, be subsequently connected to the outer tube 14 by welding, screwing or other fastening means.

The pressure in this air chamber 11 can be regulated via the valve 12 arranged in the outer wall 18 of the lower air chamber 11. So that this valve 12 can be used, a slot or an elongated hole (not shown in this figure) is let into the outer tube 14. As a result, valve 12 remains in position regardless of whether outer tube 14 is in the position shown in this figure or otherwise. This valve 12 can be used, for example, to regulate how much air must penetrate the lower air chamber 11 until this air pushes the annular piston 20 or the outer tube 14 upward. If this valve 12 is closed, a small amount of air is sufficient to cause the cymbal plates 3, 4 to collapse and a sound as a result of the downward movement of the outer tube 14. In this case, the instrument 1 would be set in such a way that the lower cymbal 4 strikes the middle cymbal 3 much earlier than the upper cymbal 2 when the pedal 31 is actuated Air is pressed from the lower cylinder chamber 23 into the lower air chamber 11 until the outer tube 14 starts to move. Such an adjustment would have the consequence that the lower cymbal plate 4 only hits the central cymbal plate 3 after the upper cymbal plate 2. The two sounds would be offset in the other order. Of course, the valve 12 can also be set so that the upper cymbal plate 2 and the lower cymbal plate 4 hit the middle cymbal plate 3 at the same time, which leads to a significantly fuller sound. It is also possible to complete by Opening the valve 12 completely switches off the subsystem of the instrument 1 with the lower cymbal plate 4. In this case, of course, the air, which is pressed out of the lower cylinder chamber 23, searches through the valve 12 for the path of lower resistance to that in which the annular piston 20 has to be pushed up.

The valve 37 in the outer wall 44 serves to regulate the upper air chamber 19. The spring effect which is achieved by the air in this air chamber 19 can be controlled in the first place. When the valve 37 is completely closed, this spring is set to a certain extent hard. The outer tube 14 pops up after actuation of the pedal 31 and back again due to the spring action. The air compressed by the upward movement of the outer tube 14 tends to expand again and pushes the outer tube 14 back into the starting position. The further the valve 37 is opened, the more this effect decreases as the spring action diminishes.

The upper air chamber 19 is located above the annular piston 20. The upper and lower air chambers are sealed airtight from one another via an annular groove 24 and an O-ring 22. The air in the upper air chamber 19 is compressed by the upward movement of the annular piston 20 until a spring effect occurs. The air tends to expand again, the annular piston 20 and thus the outer tube 14 lower again. As a result, the air in the lower air chamber 11 continues to press through the openings back into the lower cylinder chamber 23. This air, in conjunction with the restoring force triggered by the action of the return spring 33, presses on the rod 7. This triggers an upward movement of the piston 8 and thus a return of the instrument 1 to its starting position. The dead weight of the lower cymbal plate 4 and the outer tube 14 are dimensioned such that when the pedal 31 is actuated they support or cause this process of the return of the lower cymbal plate 4 and the outer tube 14 to the starting position. The air compression takes place because the piston 8 also has at least one O-ring seal. Various sealing measures are intended to ensure that the system is properly sealed to the outside. In this exemplary embodiment, systems consisting of an annular groove with an inserted O-ring are selected. So serve as the lower end of the cylinder chamber 23, the annular groove 27 with O-ring 28, and as the upper end of the upper cylinder chamber 10, the annular groove 38 with O-ring 39 and the end of the upper air chamber 19, the annular groove 40 with O-ring 41.

In the embodiment according to FIGS. 8 and 9, the movable outer tube 14 is also covered by a cladding tube 16, so that any risk of injury is avoided. With 29 another ring groove and with 30 another O-ring are indicated, which can be used if one cannot cope with the one seal 42, 43, for example because the piston 8 has a correspondingly large length. With 32 the outer wall of the lower air chamber or the outer air chamber is referred to, which is acted upon via the outlet 9 when the compressed air escapes here.

All of the features mentioned, including those that can be seen in the drawings alone, are regarded as essential to the invention, alone and in combination.
