consiste en un cuerpo que situado verticalmente adopta la configuracion plantar rectangular, cuya superficie presenta una pluralidad de perforaciones de planta rectangular, disponiendo en la zona central del area concava, de un resalte que visto frontalmente adopta la forma de una "U", cuyas ramas verticales presentan prolongaciones laterales, y en el area posterior o zona convexa, el cuerpo vertical dispone en su zona central de un elemento cilindrico de altura superior al cuerpo rectangular, el cual esta dotado en su zona inferior de un resalte alar de planta circular. De este cuerpo, por la zona superior e inferior del elemento rectangular, se dimanan en sentido horizontal y en paralelo dos cuerpos paralelepipedicos, que se adosan a un marco o bastidor, formado por cuerpos prismaticos, presentando este bastidor en su zona media superior, un travesano de identica configuracion y en una altura media superior y media inferior, el bastidor frontal dispone adosado en su zona interna de dos cuerpos planos de planta rectangular. En el area cuadrangular situada en la zona superior y en la zona inferior, el cuerpo rectangular vertical formado por prismas unidos entre si, dispone adosado internamente, de pletinas angulares, planas y externamente de dos resaltes semicilindricos dotados de rehundidos armonicos externamente. En la zona inferior, existe un tercer cuerpo rectangular situado horizontalmente y en paralelo con los dos citados anteriormente. En el area frontal, el marco dispone de una prolongacion de longitud inferior que forma un rectangulo apaisado, cuya zona central dispone de un cuerpo laminar multiperforado en configuracion similar a la pieza rectangular curvada situada en la parte posterior, en la cual, se adosa un segundo cuerpo prismatico en paralelo con el soporte cilindrico situado en la parte trasera.It consists of a body that, located vertically, adopts the rectangular plantar configuration, the surface of which has a plurality of perforations with a rectangular ground plan, having a projection in the central area of the concave area that, seen from the front, adopts the shape of a "U", whose branches vertical have lateral extensions, and in the rear area or convex area, the vertical body has in its central area a cylindrical element higher than the rectangular body, which is equipped in its lower area with a circular projection flange. From this body, by the upper and lower area of the rectangular element, two parallelepipedic bodies emanate horizontally and in parallel, which are attached to a frame or frame, formed by prismatic bodies, presenting this frame in its upper middle area, a Crossing of identical configuration and in an upper half and lower half height, the front frame has two flat bodies of rectangular plan attached to its internal area. In the quadrangular area located in the upper area and in the lower area, the vertical rectangular body formed by prisms joined together, has internally attached, angular, flat plates and externally two semi-cylindrical projections equipped with externally harmonic recesses. In the lower area, there is a third rectangular body located horizontally and in parallel with the two mentioned above. In the front area, the frame has a lower length extension that forms a landscape rectangle, the central area of which has a multi-perforated laminar body in a configuration similar to the curved rectangular piece located at the back, in which a second prism body in parallel with the cylindrical support located at the rear.
