BARRERA CONTRA INTRUSOS PARA MONTARLA SOBRE UNA PARED |
摘要 |
<p>An intruder barrier for mounting on the top or side face of a wall is provided. The intruder barrier consists essentially of a scaling barrier formed from a number of blades radially arranged and rotatable about a longitudinal axis so that any attempt to climb the wall is foiled as the blades simply rotate thus not providing a firm hold for the would-be intruder.</p> |
