HRP20010829A2 - Device for the correction of intonation deficiencies in brass instruments with three or four valves - Google Patents

Description

The field of technology

Acoustics, musical instruments, trumpet: G 10 K5/00; 7/00; 9/00.

Technical problem

The intonation deficiency in brass instruments with three or four valves is solved, namely trumpet, horn, trombone with valves, tuba, wing, tenor, bass and fanfare.

Of the ten most commonly used tones from the aliquot sequence:

Correct, i.e. intonationally correct, are: 1. 2. 4. and 8. tone.

They are too high: 3rd, 6th and 9th tone.

They are too low: 5th, 7th and 10th tone.

When using the fifth, sixth and seventh tube lengths, the length of the instrument tube is insufficient, as a result of which all three vertical series of tones played at these lengths are relatively too high.

State of the art

All brass instruments produced so far are imperfect in terms of intonation.

Presentation of the essence of the invention

The device for correcting intonation deficiency in brass instruments with three or four valves is a compensating rod or pull, built into the basic length of the instrument's barrel in such a way that the basic length of the instrument's barrel is unchanged when the compensating rod is in the zero position. If the basic length of the pipe is shortened with a compensating pipe, the intonation of the derived tone is raised, and if the basic length of the pipe is lengthened with a compensating pipe, the intonation of the derived tone is lowered.

The compensation tube is 1/15 (literally: one fifteenth) of the basic length of the instrument tube. One-fifteenth of the pipe is the length of pipe that is added by turning on the second valve on the instrument.

The zero position of the compensating rod is located at a point that is a third of the distance from the end on the side where the basic length of the instrument tube is shortened.

Due to easier orientation in relation to the zero position, a spring can be installed that reaches up to 1/3 (literally: one third) of the length of the compensating rod, measured from the side of the compensating rod towards which the compensating rod shortens the total length of the pipe.

Using the described device for correcting intonation deficiency in brass instruments with three or four valves solves the problem of intonation deficiency in all brass instruments with three or four valves.

Detailed description of the method of realizing the invention

When installing a compensating bar, the quality of the work must be respected, as well as the anthropometric data.

Quality performance of work implies:

- respecting the dimensions of the instrument on which the compensating bar is installed, both the diameter and the length of the instrument;

- use of quality material;

- all soldering as well as other adjustments were done precisely.

Observance of anthropometric data implies that:

- the compensating bar must be installed in such a way that a person can use it without any interference;

- in the case of instruments on which the compensating rod is installed, changes should be made, as necessary, in the way the tube is bent so that the compensating rod is "in the hand" of a person, in order to enable use without any interference, as well as to make it possible by removing the limit screw of the maximum extension of the compensating rod easy and simple disassembly and assembly of the compensating rod for cleaning and lubrication.

List of used call signs, in the form

1 part of the basic length of the TRUBE pipe, which is replaced by a compensating pipe or puller, and this at a length of 1/15 of the total basic length of the TRUBE pipe

Possibilities of industrial application

When playing brass instruments with three or four valves, such as trumpets, horns, trombones with valves, tubas, flüglhorn, tenor - baritone, bass and fanfare, which do not have a device for correcting intonation deficiency in brass instruments with three or four valves, there are big and unsolvable problems in intonation, especially in extreme dynamics.

The invention corrects this imperfection, so it can be used to solve the intonation deficiency in the mentioned brass instruments with three or four valves, in symphonic, military brass and other orchestras.

The possibility of commercial placement is unexpectedly large, because it involves a large number of instruments that are produced in a large number of countries, for example: Austria, Argentina, Australia, Belgium, Brazil, Canada, Switzerland, Colombia, Czech Republic, Slovakia, Germany, Denmark, Spain, France, Greece, Hungary, Hong Kong, Israel, Italy, Japan, Korea, Luxemburg, Malta, Norway, Netherlands, South Africa, Russia, Sweden, Singapore, Slovenia, America, but also used all over the world. The number of instruments, the geography of producers and users reveal the possibility of great commercial success: commercial placement and profit.
