Abstract

Double doubles or double placters characterized by a main characteristic of this object that is its condition of being double, or, of unifying two placters with an axis. The shape of the "double bow" can vary, adjusting more or less to the habitual forms of the wheels that exist in the market. They are two puas and a metal rivet that joins them and allows them to rotate on their axis. The outer face of each pua presents holes that allow the transpiration of the years of the fingers or a rugged surface that facilitates the same committed regarding the sweat of the yems produced by the exercise. The inside face of each pua is polished. This allows the sliding of one pua on the other. But, at the same time, that polish must allow the two bits to be in rest when the pressure of the fingers does not exceed certain limit. This can be solved with a small protection in the internal face of one of the wheas that, in a rest, will be hosted in a small smooth on the other's internal face so that when the thumb pressure exceeds certain limit, that protuberance exit your state of rest in the slot and slide on the polished surface of the other pua. If the shape of the inner wheel (which is in contact with the index finger) is more or less triangular, with the rounded vertices, then, the upper wheel (which is in contact with the thumb finger) does not need to have a vertice with whom you are going to hit the string as your main mission is to slip on the bottom bow, although this does not prevent that your form may also present that vertice ensuring with that impact with the rope.
