[8] FIELD OF APPLICATION

[9] The present title patent and object of description and claim in this booklet is an inventive solution which finds outstanding benefit in the musical instrument industry and trade, notably percussion musical instruments. [10] DEMAND FOR INVENTION

[11] a. From the technical point of view: in view of the field of application, the applicant, expert in the field of musical instrument production, and aware of the factual reality of musicians when setting up their equipment to places where they perform musical shows, such as at home nightclubs, identified the need to offer musicians, percursionists a percussion instrument that is versatile in obtaining different sounds.

[12] b. From the perspective of transport ergonomics: it is also the desire of musicians, especially percussionists whose musical instruments are characterized by being complex, heavy and bulky, to offer a percussion instrument with technical characteristics of the drums, but which is easy to transport and assemble.

[13] REQUIREMENTS OF THE INVENTION

[14] In line with the demand of the invention the applicant has devised the "Refinement Applied in Cajón Type Percussion Instrument" provided with associated novelty of inventive activity, as it does not follow in an obvious or obvious manner from the state of the art that is formed by the instrument. Cajon, conferring advantages from an industrial, commercial and technical point of view.

[15] In addition the "invention" is provided with industrial applicability, therefore, in view of the accuracy of the patentability requirements, mainly as a patent, as set forth in the dictates of the articles 8 and 13 of Law 9.279.

[16] BACKGROUND ART

[17] In order to provide truth and to consolidate the context explained in the topics of the introductory table, an explanation of the state of the art for the ca percussion instrument and the drums percussion product will be presented, where after critical analysis of these, once evaluated by technicians in the subject, will be able to identify its limiting aspects. , thus consolidating the identification of the previously mentioned demand.

[18] a.l Of the musical instrument drums: in the state of the art several types of drums are known, among which it is pertinent to mention the electronic drums, where for the purpose of the present invention the applicant chooses the conventional drums as a paradigm of study.

[19] The conventional drums are basically composed of driving plate, attack plate, Chinese plate, deaf, tom-tom, bass drum, box, chimbau, tambourine, sound block, bell and others.

[20] a.2 Positive aspects: In view of the large number of musicality devices embedded in a drum it is a fact that by making use of (or part of) all musicality devices gives the percussionist the possibility to carry out a large portfolio of musicians. production of distinct sounds.

[21] a.3 Problem identification: Although conventional batteries, in the most varied configurations, present technical excellence, it is relevant fact that the biggest problem of this type of instrument lies in its own constructive complexity, as can be verified by reading the previous paragraph. .

[22] In turn, this complexity brings with it the negative aspect that it needs to occupy considerable space of useful area, which is potentiated with reference to the place of use, the assembled stages for shows in medium / small venues. postage. [23] Another negative aspect, also due to this constructive complexity is the fact that it makes the assembly / disassembly operations of this instrument characterized by the operational difficulty and high time required for this, being the determining time in the set up bottleneck. "from the show area creates too much expectation as well as can lead to even delays in starting a musical show due to this set up.

[24] Finally, also due to the great complexity of the drums concept, it is a fact that for a minimal configuration, that is, a minimal musical performance acceptable to a musician is possible, the cost of obtaining such an instrument is yes very costly.

Bl Of the cajón musical instrument: As well defined in the first paragraphs of this cartouche, it is a percussion instrument of simple constructive and musical concept, being basically formed by a wooden box whose front is used to provoke sound and at the rear a wall is provided with opening, through which the amplified sound generated by the interference of the musician's hands with the front wall, also technically said as percussion, is externalized.

[26] b.2 Positive aspects: In general, from the point of view of the constructive concept, the cajón is much simpler than the battery. obtaining a lightweight and easy-to-carry instrument, where you do not need to go through the assembly / disassembly steps when performing a show, for example. Another positive aspect lies in the fact that its simple constructivity converges on an instrument that occupies little space and is therefore very suitable on stages that receive a small group of spectators. Ultimately its constructive simplicity matters in a low-cost musical instrument, accessible therefore to musicians who practice the profession on stages intended for small audiences.

[28] b.3 Identification of the problems: the careful consideration of this type of percussion instrument refers to the fact that, due to its constructive and functional simplicity, the musicians are not totally satisfied with its use, as it is a solution without sounding devices other than the front wall of the same where noise is generated, trepidation, which is little, for example, so that it is possible for percussionist musicians to generate various sounds, such as bass, treble, chime, among others. others.

[29] However, the musician making use of the conventional "cajón" musical instrument during a performance, although easy to carry and position it on stage, is always bothered by the fact that it cannot be as versatile as the instrument. Conventional battery.

[30] PROPOSAL OF THE INVENTION

[31] a. Objective: It is an object of the present invention to offer the market of musical instruments, notably for percussion instruments, a solution that aggregates in a single instrument the positive aspects of high flexibility and quality in the generation of the most varied types of sounds (verified in instruments). drums) with the positive aspects as a compact, easy-to-carry instrument and ergonomics of use recognized in the cajón percussion instrument.

[32] In addition, it is also an ancillary object of the present invention that the solution obtained also have remedied the negative aspects recognized when using the drum percussion instrument and the Cajon percussion instrument.

[33] b. Distinctive feature: In order to make the objectives of the invention feasible, a solution has been devised which, based on the technological concept of the constructive concept of a conventional type percussion instrument, adds to this concept a plurality of sounding devices, which may be for example a bass drum, a tone, a box, among others, thus resulting in an improved cajón percussion instrument.

[34] c. Desired technical effect: The improved cajón instrument is versatile in sound production, being compact, easy to transport and positioning in its place of use, for example on a stage stage.

[35] d. Instructions for use: The improved cajón instrument can be used both in isolation, and can also be used as an integral part of other battery components, such as in combination with musical devices such as cymbals attack plate, Chinese dish) on their easels, chimbau, tambourine and pedal, among others.

Already the interference of the musician next to the improved cajón notably next to its aggregate sounding devices can be realized by the use of drumsticks, brooms or bobbles, or even with the own hands.
