Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO TELESCOPICO BLOQUEABLE (1) QUE INCLUYE UN TUBO CILINDRICO (10) Y UNA BARRA O VASTAGO DE PISTON (3). LA BARRA O VASTAGO DE PISTON (3) INCLUYE UN DISPOSITIVO DE BLOQUEO EXPANSIBLE (60) QUE, CUANDO SE ENCUENTRA ACTIVO, SE EMPOTRA A LA FUERZA A UNA PARTE DE LA PARED INTERIOR DEL TUBO (10). EL DISPOSITIVO DE BLOQUEO EXPANSIBLE (60) INCLUYE DOS MANGUITOS (61, 62) QUE SE MUEVEN JUNTO CON LA BARRA O VASTAGO DE PISTON (3) EN LA DIRECCION LONGITUDINAL DEL DISPOSITIVO (1). CUANDO SE ROTAN LOS MANGUITOS (61, 62) UNO RESPECTO AL OTRO CON LA AYUDA DE UNA PALANCA (51) QUE HAY MONTADA SOBRE LA VARILLA DE PISTON, SE BLOQUEAN LA VARILLA DE PISTON (3) Y EL TUBO (10) DE MODO QUE NO SE PUEDAN MOVER UNO RESPECTO AL OTRO. LA INVENCION TAMBIEN SE REFIERE AL USO DEL DISPOSITIVO TELESCOPICO BLOQUEABLE JUNTO CON LAS DENOMINADAS PIEZAS DE ASIENTO DEL MOTOR.
