Tal como se puede apreciar en las figuras, el dispositivo de seguridad de la presente invención comprende un cuerpo 1 que se puede acoplar a un peldaño 2 de una escalera de mano 3.As can be seen in the figures, the safety device of the present invention comprises a body 1 that can be attached to a step 2 of a ladder 3.
Este cuerpo acoplable 1 es, según la realización representada, una placa doblada de manera que se define una sección transversal en forma de U, en el interior de la cual queda alojado el peldaño 2 de la escalera 3.This attachable body 1 is, according to the embodiment represented, a bent plate so that a section is defined U-shaped cross, inside of which it is housed the step 2 of the ladder 3.
Este cuerpo acoplable 1 comprende un elemento de sujeción 4, que preferiblemente es un saliente colocado en la parte superior frontal de dicho cuerpo acoplable 1. La finalidad del elemento de sujeción 4 es sujetar una cuerda de seguridad 5 que se coloca en contacto con dicho elemento de sujeción 4.This attachable body 1 comprises an element of fastener 4, which is preferably a projection placed in the part upper front of said attachable body 1. The purpose of the fastener 4 is to secure a safety rope 5 that placed in contact with said fastener 4.
Dicha cuerda de seguridad 5 se extiende a lo largo de prácticamente toda la escalera 3. En concreto, la cuerda 5 está fijada en su extremo superior a un elemento de fijación 7, que puede ser, por ejemplo, una anilla o un mosquetón, mientras que el extremo inferior de la cuerda d seguridad 5 se fija a un peldaño inferior (no representado) de la escalera 3.Said safety rope 5 extends to the along virtually the entire ladder 3. Specifically, the rope 5 is fixed at its upper end to a fixing element 7, which it can be, for example, a ring or a carabiner, while the lower end of safety rope 5 is fixed to a step bottom (not shown) of the stairs 3.
Tal como se aprecia con mayor detalle en la figura 2, la cuerda de seguridad 5 pasa por detrás del poste 6 en el cual se apoya la escalera de mano 3.As can be seen in greater detail in the Figure 2, the safety rope 5 passes behind the post 6 in the which supports the ladder 3.
Para conseguir el acoplamiento estable del cuerpo acoplable 1 a la escalera 3, este cuerpo acoplable 1 comprende un elemento desplazable 9, cuya posición se puede ajustar a la distancia entre dos peldaños adyacentes 2 de la escalera 3, de manera que el extremo inferior de dicho elemento desplazable 9 queda acoplado al peldaño 2 colocado por debajo del cuerpo acoplable 1.To achieve stable coupling of body attachable 1 to ladder 3, this body attachable 1 it comprises a movable element 9, whose position can be adjusted at the distance between two adjacent steps 2 of the ladder 3, of so that the lower end of said movable element 9 is coupled to step 2 placed below the attachable body one.
El ajuste de la posición de dicho elemento desplazable 9 se realiza mediante una clavija 11 que se desliza a lo largo de una ranura 10 prevista en dicho elemento desplazable 9. Esta clavija 11 comprende medios para bloquear su movimiento de deslizamiento, tal como por ejemplo un tornillo o similar.The adjustment of the position of said element movable 9 is made using a pin 11 that slides to along a groove 10 provided in said movable element 9. This pin 11 comprises means to block its movement of sliding, such as a screw or the like.
Para impedir el deslizamiento accidental de la escalera 3 respecto al poste 6, el cuerpo acoplable 1 comprende en su parte posterior un elemento de tope 8, formado por una lámina de goma con una superficie ranurada o rugosa.To prevent accidental sliding of the ladder 3 with respect to the post 6, the attachable body 1 comprises in its rear part a stopper element 8, formed by a sheet of rubber with a grooved or rough surface.
Para utilizar el dispositivo de seguridad de la presente invención, en primer lugar el operario ata a través de su cintura una cuerda de seguridad 5, de manera convencional, mediante unos mosquetones y un dispositivo anticaídas antideslizante (no representados).To use the security device of the present invention, firstly the operator ties through his Waist a safety rope 5, in a conventional manner, by some carabiners and a non-slip anti-fall device (no represented).
A continuación, estando el operario en el suelo, éste fija el extremo superior de la cuerda 5 al cuerpo acoplable 1 mediante el elemento de fijación 7. Seguidamente, apoyando la escalera 3 en el poste 6, el operario pasa la cuerda de seguridad 5 alrededor del poste y alrededor, por lo menos parcialmente, del elemento de sujeción 4, de manera que la escalera 3 queda fijada al poste 6.Then, while the operator is on the ground, it fixes the upper end of the rope 5 to the attachable body 1 by means of the fixing element 7. Next, supporting the ladder 3 on post 6, the operator passes the safety rope 5 around the post and around, at least partially, the fastener 4, so that the ladder 3 is fixed to the post 6.
Así, cuando el operario empieza a subir por la escalera 3 ya está sujeto a la escalera 3, la cual, por su parte está sujeta al poste 6, evitando cualquier posibilidad de caída accidental, mientras sube por la escalera, mientras trabaja en el poste y mientras baja por la escalera.Thus, when the operator begins to climb the ladder 3 is already attached to ladder 3, which, in turn It is subject to post 6, avoiding any possibility of falling accidental, while climbing the ladder, while working on the post and while going down the stairs.
A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el dispositivo de seguridad descrito es susceptible de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser substituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas.Although reference has been made to a Concrete embodiment of the invention is evident to an expert in the matter that the described security device is susceptible of numerous variations and modifications, and that all the details mentioned can be substituted by others technically equivalent, without departing from the scope of protection defined by the attached claims.
