DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDADESCRIPTION OF THE PREFERRED EMBODIMENT
A continuación se realiza una descripción de la invención basada en las figuras anteriormente comenta- das .A description of the invention based on the previously mentioned figures is given below.
Así, la pantalla de protección facial de la invención se constituye a partir de una única pieza determinada por una lámina 1 que está dotada de una banda 2 que se une a través de un puente 3 con la pantalla 4. La lámina 2 presenta en uno de su extremos unos entrantes transversales 5 y en el otro extremo dos ranuras longitudinales 6 que incluyen unas expansiones laterales definiendo triángulos.Thus, the face shield of the invention is constituted from a single piece determined by a sheet 1 which is provided with a band 2 that joins through a bridge 3 with the screen 4. The sheet 2 has one from its ends some transverse recesses 5 and at the other end two longitudinal grooves 6 that include lateral expansions defining triangles.
La pantalla 4 presenta en proximidad a sus vértices superiores dos ranuras paralelas 7.The screen 4 has two parallel grooves 7 in proximity to its upper vertices.
Para montar la pantalla para su utilización, se produce el arqueo del puente 3 sobre una de las caras de la pantalla 4 y a continuación se introducen los extremos de la banda 2 a través de las ranuras 7 (figura 1). De esta forma la banda 2 constituye el arnés que faculta la fijación de la pantalla a la cabeza del usuario, para lo que se introduce en la ranura 5 a través de una de las ranuras longitudinales 6, para posteriormente efectuarse el enclavamiento en uno de los triángulos previstos lateralmente a dichas ranuras longitudinales 6 quedando la careta perfectamente fijada a la cabeza del usuario .To mount the screen for use, the arching of the bridge 3 is produced on one of the faces of the screen 4 and then the ends of the band 2 are introduced through the slots 7 (Figure 1). In this way, the band 2 constitutes the harness that allows the fixing of the screen to the user's head, for which it is inserted into the groove 5 through one of the longitudinal grooves 6, to subsequently interlock in one of the triangles provided laterally to said longitudinal grooves 6 leaving the mask perfectly fixed to the user's head.
En el ejemplo de realización la banda 2 presenta en su zona central un tramo de mayor anchura que tras un escalonamiento 8 determina un tramo de menor anchura, de forma que el escalonamiento 8 define un tope de introducción de la banda a través de la ranura 7.In the exemplary embodiment, the band 2 has in its central area a section of greater width that after a step 8 determines a section of smaller width, so that the step 8 defines a stop for introducing the band through the slot 7 .
Evidentemente, el bloqueo del posicionado de los entrantes transversales 5 sobre uno de los triángulos de la ranura 6, se elige de forma que la longitud de su banda 2 se adapte perfectamente a la medida de la cabeza del usuario. Obviously, the blocking of the positioning of the transverse recesses 5 on one of the triangles of the groove 6 is chosen so that the length of its Band 2 fits perfectly to the user's head size.
