Description

  The present invention relates to an improved percussion instrument. More particularly, the present invention relates to an improved percussion instrument of any diameter and height, in the form of a drum, perhaps a percussion instrument provided with a tailpiece, commonly used with drums, possibly with other similar elements.

  The most common percussion instrument is typically a support or torso made of a ring-shaped band that is sealed by an equal number of stretched membranes or skins on opposite sides. It is known that it is a so-called drum that is generally constructed. The film or skin strike by hand, typically performed by a drumstick, produces a traditional sound with a rhythmic function that is caused by vibrations caused by the player. For some types of drums, you can even find the tailpiece. That is, it is possible to find a piece of a piece basically formed of braided metal wire that can be tightly clamped to one of the skins to produce an outstandingly strong sound.

  In conventional drums, the skin that seals the ring-shaped band on opposite sides is shaped to fit each edge of the band along its circumference and is clamped to the band by a ring that engages a threaded connecting rod It is done. More specifically, a metal ring having a plurality of receiving seats provided at equal intervals for inserting a threaded connecting rod is press-fitted into the skin disposed on the opposite edges of the band. It is done. The threaded connecting rod engages an equal number of metal blocks clamped to the outer surface forming the drum body. Each block has opposing threaded holes that extend parallel to the vertical axis of the barrel and are mounted along screws and opposing lower edges that clamp the drum head located above. Receive both screws to stabilize the head with others. Alternatively, two sets of blocks are fastened to the side band forming the drum body, and each set is suitable for fastening one connecting rod of the drum head skin. Along the side band of the conventional drum body, an opposing tailpiece tensioning device can be found, which is secured by means of further screws or equivalent means, this tailpiece tensioning device comprising a so-called tuning gear and a wire. And a support body that is tightened at positions opposite to each other in the diametrical direction.

  This conventional embodiment has been found to cause significant problems.

  Indeed, the large number of threaded seat blocks along the outer surface of the torso actually distorts the purity of the sound produced by the strike, and the surface does not respond regularly to vibrations, which is a tuning problem. It is understood that

  A further serious problem with some types of known drums is related to the tension of the opposite drum head skins, which in some cases both skins are secured to each block. Cannot be measured correctly in an independent manner. Thus, the tension of one skin, at least in part, affects the tension of the other skin.

  The object of the present invention is to eliminate the above problems.

  More specifically, it is an object of the present invention to provide an improved percussion instrument, i.e. a drum, which guarantees the absolute purity of the sound emitted by the percussion of the skin.

  A further object of the present invention is to provide a musical instrument as described above that can be easily tuned.

  Furthermore, the object is to provide a drum in which the opposite skins can be tensioned in an independent and measurable manner.

  It is a further object of the present invention to provide a drum that can be used without any modification of conventional skins and associated existing clamping rings.

  It is a further object of the present invention to make available to the user such a drum that is in a state of guaranteeing a high level of strength and reliability over a long period of time and is manufactured simply and inexpensively.

  This and other objects include a cylindrical body or barrel that is provided with a skin, wherein the skin is cylindrical with a ring incorporating a plurality of embossed appendages having axial holes. An improved percussion instrument of the present invention fixed to each of opposite surfaces of the ring-shaped band, wherein the upper and lower edges of the torso are bent outwardly and are provided with one or more tongue-shaped bands And is achieved by a percussion instrument characterized in that the tongue is specially designed to engage the appendage in stabilizing the ring.

  The structural and functional features of the improved percussion instrument of the present invention provide preferred embodiments, but are read below with reference to the accompanying drawings, which are not intended to limit the invention to the form as disclosed. It can be further understood by explanation.

  Referring to the drawings, the improved percussion instrument of the present invention, indicated generally at 10 in FIG. 1, is comprised of a cylindrical body 12 or torso, on opposite surfaces of the cylindrical body or torso, A drum of any diameter and / or height to which the skin 14 defined by possibly metal rings 16, 18 is secured. This body is also advantageously made of a metal such as bronze, copper, steel or titanium, and according to the invention, the upper and lower edges of the body 12 opposite to each other are bent outwardly, Ring-shaped bands 20 and 22 extending in parallel with and adjacent to the main body are formed. Such a folding height is illustratively associated with the corresponding height of the body 12 and is 15-50 mm.

  The width of the ring-shaped hollow portion 24 formed by the folding, that is, the distance between the outer surface of the main body 12 or the trunk and the inner surface of the folding is in the range of 1 to 10 mm, preferably in the range of 3 to 6 mm.

  The ring-shaped bands 20 and 22 formed by folding the upper and lower edges of the main body 12 or the body portion are further advantageous to the outside of the main body 12 and against the side surface of the main body itself, as shown by the example of FIG. Are bent in a direction orthogonal to each other to form an uninterrupted tension unit having a limited width, or preferably a plurality of tongues 26 of any shape provided at equal intervals. The number of tongues 26 varies in relation to the size or diameter of the body 12, which itself corresponds to the size or diameter of the corresponding embossing appendage 28 of a known type of ring 16,18. These rings are conventionally located along the tongue 28 of a vertically extending through hole 30 for insertion of a screw or threaded connecting rod 32.

  The tongue 26 formed by the folding of the ring-shaped bands 20 and 22 is also provided with through-holes 34 that align with the holes 30 in the rings 16 and 18.

  Once the skin 14 is attached to the opposite edges of the body 12, the rings 16 and 18 are pressed onto the skin to align the ring holes 30 with the holes 34 in the tongue 26.

  Then, as shown in detail in FIG. 2, a rod 32 of an appropriate length is inserted into the hole 30 and extended until a portion of the threaded rod protrudes from the hole 34 in the tongue 26.

  A conventional nut 36 or equivalent member secures the rings 16 and 18 to the skin 14 using screws 32 and allows the skin to be tightened to the body 12. Advantageously, thanks to the independent skin tension achieved by the screws 32 that engage the rings 16 and 18 with the tongues 26 of the ring-shaped bands 20 and 22, one skin tension can be applied to the instrument player. In relation to the demands of the other skin. Further advantageously, such an anchoring does not require prior arrangement of a block that is integral with the outer surface of the body 12 or torso, so that any degradation in the purity of the sound emitted by the strike. Can be avoided.

  In addition, the conventional gear and the opposing wire fastening device, possibly extending the tailpiece (not shown) provided, are appropriately spaced from the body or barrel 12 as shown in FIG.

  The gear referenced 40 is actually clamped to one of the tongues 26 of the ring-shaped band 22 of the body 12 by a known means of the type such as a bracket, and the opposing wire referenced by reference 44. The fixing device 42 is also fixed in the same manner. The tongue 26 on which the gear 40 and the device 42 are located may be clearly different from the tongue 26 in shape and / or extension and is provided at any suitable position along the ring-shaped band 22 or 20. May be.

  As noted from the above disclosure, the advantages achieved by the present invention are significant.

  In the percussion instrument of the present invention, the tightening of the skin 14 by the rings 16 and 18 is integral with the main body 12 or the trunk and does not require the arrangement of the engaging member protruding from the main body or the trunk, so that the pureness of the sound is obtained. Possible degradation can be avoided. Therefore, this instrument can be tuned more easily.

  The possibility of tightening the skin 14 to the body 12 in an independent manner also allows the skin to be tensioned in the most appropriate manner in relation to the moment requirements.

  Last but not less important is the additional benefit gained from the possibility of adapting a body or barrel 12 of appropriate diameter to a conventional skin and associated lock ring without further modification.

  The invention has been described with reference to preferred embodiments that are provided for purposes of illustration and description, and are not intended to be exclusive or to limit the invention to the precise forms disclosed.
