The invention relates to a B trumpet according to the Claim 1.
Wind instruments such as trumpets, trombones and horns are known in various designs. Exemplary here are the AIDA for single valve versions Trumpet, for two-valve versions the trombone, for the group of trumpets the B and ES trumpets, the Concert trumpet, the cornet trumpet and the Called valve horns. The types and designs are detailed in various specialist books described. In this regard, an example is given to the Specialist book "The Trumpet" by Edward Tarr, published in Schott Verlag, 2nd edition 1984, as well as that of Curt Sachs published "Real Lexicon of Musical Instruments" 1962, published in the Georg Olms publishing house, Hildesheim, referred.
All known wind instruments with valves have one Mouthpiece, a conical leadpipe and a transition pipe with a certain inner diameter whose Outlet opens into the valve inlet opening.
All wind instruments are special Importance that the air flow through the pipes of the Wind instrument up to the horn if possible is passed through without vortex formation. Both known wind instruments of the generic type, especially if the leadpipe is a transition pipe or a tuning slide that is slidable on pipe pieces of the Mouth tube and the inlet tube of the valve arranged is, is attached are at the transitions through the Gradation from one pipe cross-section to another Vortex formation given. On the other hand, with horns, e.g. B. with the Prince Pleßschen and Parforce Horn or also known for fanfares, the leadpipe and all others subsequent trains from the inlet of the Mouth tube up to the bell horn continuously to let rise, which makes an almost vortex-free Drafts inside the wind instrument tubes is guaranteed and thus sound distortion as far as possible can be avoided by vortex formation.
A valve trumpet is known from DE 17 72 973 B2 an injection pipe, a valve group, one over a Deflection tube connected to the valve group Bell and a telescope against each other displaceable pipe sections formed spacer known in which the injection tube directly to the Valve group is connected and the tuning part off a single one arranged at the outlet of the valve group There is a pair of telescopic tubes, one of which is firmly attached to the tube Valve group and its other pipe with the bell connected is. From the removable mouthpiece to the This increases the inlet connection in the valve group Blowing pipe included. This trumpet is a classic ES trumpet, the total length of which is from the B-flat trumpet deviates. All B trumpets, however always have an extension to the leadpipe provided ballot on the length of the overall train significantly determined. This is for B-flat trumpets approx. 128 cm from the insertion opening of the leadpipe to Horn edge. This tuning slide is with everyone known designs as a uniform tube part formed, the bottom piece on two parallel tubes is slidably arranged. This can change the voice be adjusted. The in the mentioned publication ES trumpet described has such a tuning slide Do not extend to the mouthpiece. To vote is - as with all ES trumpets - the exit tube slidably arranged on a guide tube so that the exit pipe together with the bell is movable.
With B-flat trumpets, however, this part is usually provided stationary or else the two pipes with each other via a cylindrical arc tube part connected. DE 17 72 973 B2 does not exist in any way a suggestion for the special construction of a B-flat trumpet.
Furthermore, a flugelhorn is known from US Pat. No. 1,438,363 known, in which - like an ES trumpet above-described type - the blowing pipe or the mouth pipe opens directly into the first valve. From this writing it is generally known, however, intermediate pipe pieces to be conical. A suggestion for a new design a B trumpet is not to be found in this document.
From the FR-PS 397 865 is a screw fastening one Shaft end of a mouthpiece on the leadpipe known which purpose a cylinder piece with a Internal thread is provided, in which an external thread on Shaft of the mouthpiece can be screwed in. The shaft has a conical shaft bore. A Screw connection of the same type is also from the U.S. Patent 3,474,698 known.
The use of different materials for individual pipe parts of a trumpet are from the DE-PS 36 56, and the AT-PS 35 733 known. The Use of such sections, for example made of wood, in B-flat trumpets in connection with the special design According to the present invention, these documents are not refer to.
The invention is based, which aerodynamic advantages given with horns are, also with a B-flat trumpet with valves achieve a higher sound quality even with to achieve valve-operated wind instruments, wherein in various design levels improvements to the Sound quality should be achieved. A Bb Trumpet is said to can be realized with a new design.
The invention solves the problem by the in the claim 1 specified technical teaching, which makes an essential Improve airflow conditions below Avoidance of air vortex formation is achieved.
Advantageous developments of the invention are in the Subclaims specified in detail.
Surprisingly, it has been found that Use of wood instead of non-ferrous metal for individuals Trains, leadpipe or bell individual timbres are achievable. Accordingly, the invention also sees that Use of wood as an alternative.
Thus, according to the teaching of claim 1 Vortex formation of the draft inside the mouth tube the transition point to the transition tube or a tuning slide a trumpet avoided by the teaching of Claim 1 both pipe parts are integrally formed and have a continuous inner surface, so that it No joints or at staggered joints Vortex formation can come. Especially with one known, slidable tuning slide of a B-flat trumpet, the the transition tube forms, are at least two Vortex formation points are given that the draft in the Noticeably impair the pipe system of the wind instrument, which changes the sound quality. The invention gives a new type in relation to a B-flat trumpet. Of the Tuning slide in front of the valve cannot be moved, however in provided in the usual way for the case of Bb trumpets realizing total train length of approx. 128 cm. If, in addition, the one known for horns Form of training is used, so the conical serves Enlargement of the cross section of the leadpipe and the Tuning train up to the inlet opening of the valve Optimization of the air flow without vortex formation.
Because valve wind instruments but also other trains and Valve transitions, it is recommended to use it also the bores of the following pipe sections or the bores of the valve blockages are conical to expand in the direction of the draft, insofar as this is structurally possible. For example, this is for the valve trains in terms of dismantling the same practically only possible in the form that the individual pipe sections have conical bores, strung together a continuous conical hole form. The outside diameter, at least in that Connection area part, but are purely cylindrical, to push the trains onto the connecting pipe parts and to enable the same to be attached thereto. For Attachment are known in the bell and used screw clamp connectors on some trains.
In the event that the holes in the closures of the Valves are also conical, it is recommendable, also the connecting pipes between the With a multi-valve wind instrument tapered inner tube diameter to practically starting from the mouthpiece over the leadpipe up to the bell and the outlet opening To reach pipe diameter, the conically increasing runs.
In the context of the invention it is also established been that noticeable impairment of the Sound quality through the transition of the mouthpiece in the Leadpipe is given. As is well known, the mouthpiece a tapered shaft that fits into the Leadpipe is used. There is a on the mouthpiece end Heel added to the leadpipe. At this point arises a vortex when blown into the mouthpiece and the sound is formed. This vortex affects the Sound quality of the generated sound is already noticeable. In special embodiment of the invention according to the Claims 6 and 7 is therefore additionally provided that here too the bore in the mouthpiece of the Soul rises slightly and into the bore of the Mouth tube with a smooth inner surface passes without there are joints that create an air vortex can cause blown air.
The attachment of the mouthpiece can be different Way. The easiest is a screw cap with external thread on the mouthpiece shaft, which in one corresponding internal fine thread of the tube engages, the thread lengths are coordinated so that the bore surfaces of the bore in the mouthpiece and merge into the leadpipe. It is also conceivable to use a bayonet lock, one Restriction lock, with the protruding at the mouthpiece Cones in corresponding oblique or offset Engage locking recesses in the leadpipe.
Such fittings are for example from the Specialist book by O. Richter-R. v. Voss-F. Kozer "components der Feinmechanik ", published by Verlag Technik Berlin 1954, page 138. Unidirectional connections, too, Bayonet connections or bayonet lock are called also from the same textbook, page 158 ff. known. Such restriction connections should be used Ensuring a tight fit of the mouthpiece Have wedge surfaces.
The invention is based on the in the Exemplary embodiments shown in drawings explained.
The drawings show:
Fig. 1 is a B-trumpet according to the invention with three valves, a mouth tube and a transition tube, the transition tube is arc-shaped, similar to a displaceable tuning slide,
Fig. 2 is a mouthpiece with a screw attachment on the leadpipe and
Fig. 3 shows a mouthpiece with a bayonet lock for attachment to a leadpipe.
In Fig. 1 a according to the invention formed B-trumpet is shown with a loop-shaped bent tuning slide 2, which terminates with its end on the valve 4, and opens into the valve bore. The entire tuning slide 2 is conical, so that the advantages that are given when pulling a horn are also realized here. Furthermore, the leadpipe is correspondingly conical, so that there is a closed inner surface of the bore without impact. To reinforce the leadpipe 1 , a sleeve can also be mounted on it and fastened to it, so that the instrument experiences greater stability and mechanical strength.
The trumpet also has a so-called machine with three valves 4 , 5 and 6 . The valves used are, for example, P´rinet valves with spiral printing units with vertical plungers 12 , 13 , 14 with plate-shaped actuating elements. Passages 19 , 20 are provided between the valves with the interlocks which can be actuated via the tappets 12 , 13 , 14 . Furthermore, the first valve 4 has a valve train 7 to which a finger ring for retuning is attached. The train 7 is displaceably fastened to pipes of different lengths, which open into the valve 4 and are fastened thereon. On the second valve 5 , the second train (halftone train) is provided, which is also connected as a pipe part to the outlet and inlet openings of the valve and is incorporated into the air flow by actuating the valve. Furthermore, a whole tone train 8 is provided on the third valve 6 . This train is also attached to the valve 6 via offset pipes on which it is slidably attached. A thumb hook 15 provided thereon also serves for retuning. The outlet of the valve 6 opens into the tube of the bell 10 . This can be provided in a movable manner on a piece of pipe on the valve 6 , so that detuning can be carried out by longitudinal displacement. To secure the sliding piece, a clamping screw 9 is provided, by means of which band clamps are provided on the respective train for clamping the respective piece of pipe. From Fig. 1 it can also be seen that the halftone train 18 is arranged approximately 47 ° inclined to the longitudinal axis of the valve. In order to stabilize the leadpipe on the machine, a support element 21 is provided. A mouthpiece of known type is inserted into the insertion opening of the mouth tube 1 . The sound generated by the instrument is emitted via the sound funnel 16 .
As a special feature, this B-flat trumpet has, compared to all known designs, that at least the tuning slide 2 is conical from the mouth pipe end to the valve inlet, so that the inner opening area or the inner diameter of the round pipe in the area of the mouth pipe is smaller than at the other end, which is attached to the valve 4 and whose inner opening opens into a through hole in the valve housing, behind which the obstructions with the corresponding holes in the valve tappet are located. This conical design favors the air flow through the tuning slide, as with the well-known ES trumpet.
In a further embodiment, the through hole in the valve itself can also be conical, so that the advantage of favoring the air flow through the conical widening of the trains can also be transferred thereon. The same applies equally to the passages 19 and 20 between the valves. The passages and the first insertion opening, to which the tuning slide 2 is attached, should also be mounted in the height position so that the air flow can flow freely in the respective open position of the valve without deflection and flow into the pipe of the bell. Only the valve trains (halftone and full tone trains) that are still provided are still cylindrical with a continuous conical structure. This cylindrical design is necessary to allow the valve cables to move. However, it can also be achieved by appropriate conical design of the inner bores in the pipe sections on which the trains are slidably mounted, the effect or advantage of the conical design with respect to the air flow. In the case of displacement, there is an edge at the end of the guide tube. By suitable dimensioning, however, this transition can be selected so finely that the resulting vortices do not noticeably influence the tone. In addition, when the train is fully pushed on, a stop ensures that the inner surface of the receiving tube and the inner surface of the attached train have no obscurations against one another, so that no air vortices can arise at these transition points.
As a further special feature it can be provided that Form the mouthpiece briefly and directly on the leadpipe fasten without requiring a long shaft that reaches into the leadpipe and on its face strong air vortices can form.
In FIGS. 2 and FIG. 3 are examples displayed the fastening of a mouthpiece made according to the invention, where, despite the shortness of the mouth piece the same properties as given in a mouthpiece of a conventional type and the mouthpieces for valve trumpets or trombones etc. of each instrument can be adjusted.
In the exemplary embodiment in FIG. 2, a mouthpiece according to the invention and the connection to the mouth pipe 1 are shown in the center section. The mouthpiece 22 consists essentially of the boiler 23 , the edge 33 , a relatively soft shoulder 25 between the boiler and the bore and a core 24 which forms the narrowest point of the bore 28 . This mouthpiece has an external thread in extension to the shoulder 25 , with which it can be screwed into an internal thread of the mouth tube 1 which is adjusted in length. Fine threads are expediently used here, the mouthpiece 22 being fastened to the leadpipe 1 with a few turns. The length of the threaded part is adapted to the length of the internally threaded bore, so that when the turns are screwed together, the end face of the mouthpiece 22 bears against the annular contact surface in the threaded bore and the bore 28 of the mouthpiece merges into the bore 29 of the mouthpiece 1 without a transition. This makes it possible to enter the air flow into the leadpipe without offset on the abutting surfaces and thus without forming a vortex.
Another fastening variant is shown schematically in FIG. 3. This is a fastening of the mouthpiece 22 to the mouthpipe by means of a bayonet catch, for which purpose 1 guide slots 32 with vertical components and, if possible, wedge-shaped component 30 are incorporated into the lateral surface of the mouthpipe, into which a fastening pin, which results from the engaging part of the mouthpiece 22 protrudes laterally, engages and is clamped, so that the mouthpiece 22 is fixedly attached to the leadpipe and, with a similar design, as shown in FIG. 2, ensures that a transition from the bore 28 of the mouthpiece to the bore 29 occurs without offset of the leadpipe 1 is possible, so that here too no air flow vortices can arise and the advantages of the conical widening of the pipe are given, which favor the air flow.
from the mouth of the mouth tube ( 1 ) to the mouth of the tuning slide ( 2 ) at the inlet opening ( 3 ) of the valve ( 4 ) the mouth tube ( 1 ) and the tuning slide ( 2 ) are continuously conical and have a slightly increasing internal cross-section,
the air outlets of the obstructions in the valves ( 4 , 5 , 6 ) have a conical shape,
the cross section at the respective air inlet opening of the valves is smaller than at the air outlet opening, and
connect to the valves with a continuous transition the connections to the following trains ( 7 , 8 , 18 ) and / or passages ( 19 , 20 ) and / or to the bell ( 14 ).
