Percussion musical instrument characterized by being constituted by a support with adjustable height sponge to bring the string closer to the lid. (Machine-translation by Google Translate, not legally binding)

Description

Percussion musical instrument.

Object of the invention

New type of percussion drawer that can regulate the sound through its internal system thanks to which they can separate two actions that are involved in the production of sound: on the one hand the tensioning of the string, and on the other its approach to the lid ensuring permanent contact at the same time That height adjustable. In this way an improvement in the sound control

Background of the invention

Currently and within the musical instrument called percussion drawer we found several types in the market and we can distinguish between drawers without tensioners and drawers with tensioners. In some as in others we will find different ways of clamping one or several ropes or also beading calls.

Focusing on the drawers with tensioners, all they use the same arrangement to get tension: a rope carried from a point on its upper bar towards a block of lower wood and back to the upper bar thus forming what is called a V-shaped rope. This way of putting the strings have their origin in the drawers without tensioners that were precedents in the time and development of this instrument. The tension of this V-shaped string, or in some cases two ropes forming two V, is done by one or two screws that they pull that wooden bottom block and that moves the rope towards down vertically. This system has the disadvantage of tension the V-shaped rope or ropes with the risk of get an irregular tension with which it can produce harmonics or irregular unwanted sounds for the percussionist.

Description of the invention

This utility model is characterized by adopt a new way of placing and tensioning the strings or curbs in percussion drawers. Each rope is fixed and tense individually, thus achieving different tensions and therefore different sounds for each of them.

The rope (10) makes a different route to the other drawers existing in the market. Slat Part upper (1), fixed by a screw (16) and down vertically until the lower bar (2) that is fixed and has some recesses Rounded specials (20). The rope slides across the surface curved and lowered (20) of this ribbon being a few millimeters distanced from the cover (18) on the inside.

In this way it is achieved that the lid does not press the rope, leaving it with greater freedom to be subjected to tension.

Continuing its journey horizontally the rope rests on a support (8) with a spongy profile with adhesive (9) thus avoiding any unwanted harmonics because of the excessive tension of the rope.

This tension is carried out by means of a piece made of wood (5) that has a bushing (14) with an internal thread. In this bushing thread a screw (15) that pulls said piece and tension the rope which in turn is fixed by another screw (17).

This screw (15) can be tightened or loosened from the outside through the back of the drawer (19).

This new tension system may be applied to as many ropes or curbs as we wish, either even number or odd. The more ropes or curbs we lodge inside the more The high sound will increase.

In addition this utility model incorporates in its inside two slats (3), with a reinforcement (4) at each end, which they will be housed in the central part and next to the inner face of the cover (18).

In these slats, which serve as a guide, will place a new element that improves the sound result of the drawer. It consists of a support (6) to which a profile is incorporated spongy with adhesive (7), with which we get an approach from the string to the lid and in turn a sound attenuation.

This support (6) will be height adjustable and manually fixed by the percussionist, using a screw (11) and a wing nut (13) with a washer (12), thus achieving various sound nuances with which to interpret.

Description of a preferred embodiment

The support with adhesive spongy profile is adjust height manually by inserting the hand inside of the drawer and being fixed by means of a wing nut.

The tension of the strings is done from your exterior from the back-bottom by An individual screw for each rope.
