Abstract

SE DESCRIBE UN DISPOSITIVO DE BLOQUEO PARA PESCANTES POR GRAVEDAD PARA BOTES, DEL TIPO QUE COMPRENDE UN BRAZO PRINCIPAL (1) Y UN BRAZO BASCULANTE (2) EN EL BRAZO PRINCIPAL. EL EXTREMO EXTERIOR DEL BRAZO BASCULANTE ESTA PROVISTO DE UNA O MAS POLEAS (17) PARA UN CABLE DE IZADO PARA ARRIAR UN BOTE SALVAVIDAS, UNA BALSA O SIMILAR. EN DICHO EXTREMO ESTA PREVISTA UNA PIEZA DE BLOQUEO (10) PARA ASEGURAR EL BOTE SALVAVIDAS O SIMILAR EN LA POSICION DE ESTIBA DEL PESCANTE PARA BOTES. LA PIEZA DE BLOQUEO ES PIVOTABLE ALREDEDOR DE UN EJE HORIZONTAL (10A) CON RELACION AL BRAZO BASCULANTE (2). UN VARILLAJE DE CONEXION ARTICULADO SE EXTIENDE ENTRE PUNTOS DE PIVOTAMIENTO (5, 10B) EN EL BRAZO PRINCIPAL Y LA PIEZA DE BLOQUEO, RESPECTIVAMENTE, Y COMPRENDE UNA BARRA DE BLOQUEO (6) CON UNA RANURA DE GUIA (16), UNA SEGUNDA BARRA (7) Y UNA PIEZA BASCULANTE INTERMEDIA (12A, 12B) QUE TIENE DOS BRAZOS Y ESTA APOYADA A ROTACIONALREDEDOR DE UN EJE (13) QUE ES FIJO CON RELACION AL BRAZO BASCULANTE (2). EL DISPOSITIVO PROPORCIONA UNA FUNCION DE BLOQUEO AUTOMATICA Y FIABLE PARA ASEGURAR EL BOTE SALVAVIDAS EN LA POSICION DE ESTIBA DEL PESCANTE PARA BOTES AL MISMO TIEMPO QUE SE ALIVIA LA DISPOSICION DEL CABLE DE IZADO, Y PARA FIJAR EL BRAZO BASCULANTE (2) CON RELACION AL BRAZO PRINCIPAL (1) EN LA POSICION SITUADA TOTALMENTE HACIA FUERA DEL PESCANTE, RESPECTIVAMENTE.A GRAVITY DAVIT LOCKING DEVICE FOR BOATS, OF THE TYPE COMPRISING A MAIN ARM (1) AND A SWINGARM (2) ON THE MAIN ARM, IS DESCRIBED. THE OUTER END OF THE SWING ARM IS PROVIDED WITH ONE OR MORE PULLEYS (17) FOR A HOISTING CABLE TO LOWER A LIFEBOAT, RAFT OR SIMILAR. A LOCKING PIECE (10) IS PROVIDED AT SAID END TO SECURE THE LIFEBOAT OR SIMILAR IN THE STOWAGE POSITION OF THE DAVIT FOR BOATS. THE LOCKING PIECE IS PIVOTABLE ABOUT A HORIZONTAL AXIS (10A) IN RELATION TO THE SWINGARM (2). AN ARTICULATED LINK LINK EXTENDS BETWEEN PIVOT POINTS (5, 10B) ON THE MAIN ARM AND THE LOCKING PIECE, RESPECTIVELY, AND COMPRISES A LOCKING BAR (6) WITH A GUIDE SLOT (16), A SECOND BAR ( 7) AND AN INTERMEDIATE SWINGARM PIECE (12A, 12B) HAVING TWO ARMS AND IS SUPPORTED ROTATIONALLY AROUND AN AXIS (13) WHICH IS FIXED IN RELATION TO THE SWINGARM (2). THE DEVICE PROVIDES AN AUTOMATIC AND RELIABLE LOCKING FUNCTION TO SECURE THE LIFEBOAT IN THE STORED POSITION OF THE BOAT DAVIT WHILE RELIEVING THE LIFTING CABLE LAYOUT, AND TO LOCK THE TIPPING ARM (2) IN RELATION TO THE ARM MAIN (1) IN THE POSITION LOCATED FULLY OUTSIDE THE DAVIT, RESPECTIVELY.
