Tal como se puede observar en la figura 1 el casco de protección para motoristas comprende una calota o casco (10) propiamente dicho provisto de una ventana frontal y de unos mecanismos laterales para el montaje de los respectivos laterales de una pantalla (20) transparente, con posibilidad de giro entre una posición de apertura mostrada en la figura 3 y una posición de cierre de la ventana frontal mostrada en las figuras 1 y 2.  As can be seen in figure 1 the helmet for motorcyclists includes a shell or helmet (10) itself provided with a front window and lateral mechanisms for mounting the respective sides of a transparent screen (20), with possibility of rotation between an opening position shown in figure 3 and a closing position of the front window shown in figures 1 and 2.
Los mecanismos laterales para el montaje de la pantalla (20) en el casco comprenden una configuración cilindrica (101) acoplable en un hueco (201) del correspondiente extremo de la pantalla (20) y que define un eje de rotación de la pantalla (20) entre unas posiciones de apertura y cierre. The lateral mechanisms for mounting the screen (20) on the helmet comprise a cylindrical configuration (101) engageable in a recess (201) of the corresponding end of the screen (20) and defining a rotation axis of the screen (20). ) between opening and closing positions.
Dichos mecanismos laterales comprenden una primera guía (102) curva adecuada para la recepción en dirección radial y el desplazamiento circunferencial en torno al eje de rotación de un primer apéndice (202) radial de la pantalla (20); y una pieza desplazable (103) radialmente, en dirección anterior-posterior, entre unas posiciones de bloqueo y de desbloqueo de la pantalla (20). Dicha pieza desplazable (103) comprende una segunda guía (104) curva para la recepción en dirección radial y el desplazamiento circunferencial de un segundo apéndice radial (203) de la pantalla (20) en la posición de montaje de la pantalla (20) respecto al casco (10). Said lateral mechanisms comprise a first curved guide (102) suitable for the reception in the radial direction and the circumferential displacement about the axis of rotation of a first radial appendix (202) of the screen (20); and a displaceable part (103) radially, in the anterior-posterior direction, between locking and unlocking positions of the screen (20). Said displaceable piece (103) comprises a second curved guide (104) for the reception in the radial direction and the circumferential displacement of a second radial appendix (203) of the screen (20) in the mounting position of the screen (20) with respect to to the hull (10).
Según la invención los mecanismos laterales para el montaje de la pantalla comprenden una pestaña flexible (105) que tiende a mantenerse, por la propia elasticidad del material conformante de la misma, en una posición operativa de retención de la pieza desplazable (103) en la posición desbloqueo de la pantalla (20), representada en las figuras 5, 6 y 7. According to the invention, the lateral mechanisms for mounting the screen comprise a flexible flange (105) which tends to be maintained, by the elasticity of the material forming same thereof, in an operative position for retaining the displaceable part (103) in the unlocking position of the screen (20), shown in figures 5, 6 and 7.
Partiendo de la posición de montaje representada en las figura 3 y 4, el desmontaje de la pantalla (20) se puede realizar con una sola mano, tal como se muestra en las figuras 5 y 6, dado que una vez situada la pieza desplazable (103) en la posición de desbloqueo de la pantalla (20), dicha pieza desplazable (103) es retenida en dicha posición de desbloqueo por la pestaña flexible (105), pudiendo proceder a realizar inicialmente la liberación del segundo apéndice radial (203) de la segunda guía curva (104) y a continuación la liberación del primer apéndice radial (202) de la primera guía (102) curva. Starting from the assembly position shown in figures 3 and 4, the disassembly of the screen (20) can be carried out with one hand, as shown in figures 5 and 6, since once the displaceable part is located ( 103) in the unlocking position of the screen (20), said displaceable part (103) is retained in said unlocking position by the flexible flange (105), being able to initially perform the release of the second radial appendix (203) of the second curved guide (104) and then the release of the first radial appendix (202) of the first curved guide (102).
Tal como se puede observar en las figuras 8 y 9, durante el montaje de la pantalla (20) la pestaña flexible (105) es desplazada por la propia pantalla (20) hacia una posición inoperante, en la que se introduce por debajo de la pieza desplazable (103), liberando a dicha pieza desplazable (103) y permitiendo su retorno automático a la posición de bloqueo de la pantalla (20). As can be seen in figures 8 and 9, during the assembly of the screen (20) the flexible tab (105) is displaced by the screen (20) itself to an inoperative position, in which it is inserted below the displaceable piece (103), releasing said displaceable piece (103) and allowing its automatic return to the blocking position of the screen (20).
Los mecanismos laterales para el montaje de la pantalla comprenden unos muelles (106) que se comprimen cuando la pieza desplazable (103) se desplaza hacia la posición de desbloqueo de la pantalla (20) y que la retornan a la posición de bloqueo cuando la pestaña flexible (105) es desplazada hacia la posición inoperante. The lateral mechanisms for mounting the screen comprise springs (106) which are compressed when the displaceable part (103) moves towards the unlocking position of the screen (20) and which return it to the blocking position when the flange flexible (105) is moved to the inoperative position.
Los mecanismos laterales para el montaje de la pantalla (20) comprenden unos medios de retención de la pantalla en sucesivas posiciones de apertura progresiva entre una posición de cierre representada en las figuras 1 y 2 y una posición de máxima apertura representada en la figura 3. Dichos medios de retención comprenden una pieza de perfil ondulado (107) contra la que actúa lateralmente un tetón (204) de la pantalla (20), determinando dicho perfil ondulado (107) las diferentes posiciones de apertura de la pantalla (20). The lateral mechanisms for mounting the screen (20) comprise means for retaining the screen in successive positions of progressive opening between a closed position shown in figures 1 and 2 and a position of maximum opening represented in figure 3. Said retention means comprise a corrugated profile piece (107) against which a lug (204) of the screen (20) acts laterally, said wavy profile (107) determining the different opening positions of the screen (20).
Como se puede observar en las figuras 2 y 10 el casco comprende en la zona frontal un pestillo de bloqueo (108) de la pantalla en la posición de cierre y en los laterales unos medios elásticos (109) de empuje de la pantalla hacia una posición de apertura. En las figuras 1 y 2 la pantalla (20) se encuentra retenida en la posición de cierre por el pestillo de bloqueo (108) y en dicha posición de cierre los medios elásticos (109) se mantienen comprimidos por la propia pantalla (20). En el ejemplo mostrado la pantalla (20) actúa contra los medios elásticos (109) por medio de un tope (205) definido en la misma. As can be seen in figures 2 and 10, the helmet comprises in the frontal area a locking latch (108) of the screen in the closed position and in the sides elastic means (109) for pushing the screen towards a position opening. In figures 1 and 2 the screen (20) is retained in the closed position by the locking latch (108) and in said closing position the elastic means (109) are kept compressed by the screen (20) itself. In the example shown, the screen (20) acts against the elastic means (109) by means of a stop (205) defined therein.
Tal como se muestra en la figura 10 cuando se libera el pestillo de bloqueo (108) de la pantalla (20) en la posición de cierre, dichos medios elásticos (109) actúan contra la pantalla, más concretamente contra el tope (205) de la pantalla, provocando el giro de la pantalla (20) desde la posición de cierre mostrada en las figuras 1 y 2 hacia una primera posición de apertura representada en la figura 10. As shown in Figure 10 when releasing the lock latch (108) from the screen (20) in the closed position, said elastic means (109) acts against the screen, more specifically against the stop (205) of the screen, causing the screen (20) to rotate from the closed position shown in figures 1 and 2 to a first open position shown in figure 10.
En el ejemplo mostrado la configuración cilindrica (101) acoplable en el hueco (201) del correspondiente extremo de la pantalla (20) está definida en una pieza montada sobre el casco (10) y que puede desplazarse ligeramente en la misma dirección que la pieza desplazable (103), tendiendo a mantenerse distanciada de dicha pieza desplazable por la acción de un muelle (110). In the example shown the cylindrical configuration (101) engageable in the recess (201) of the corresponding end of the screen (20) is defined in a piece mounted on the helmet (10) and that can be moved slightly in the same direction as the piece movable (103), tending to stay distanced from said displaceable piece by the action of a spring (110).
