El mantenimiento de los elementos de infraestructura tales como los cableados de los sistemas de comunicaciones, redes de transmisión y distribución de energía, redes de gas, redes de acueducto y de aguas residuales ubicados subterráneamente requiere de cajas de paso y cámaras intermedias, que se convierten en puntos críticos para la seguridad de dichas redes. Además de evitar el acceso no autorizado a las redes subterráneas, este tipo de dispositivos busca prevenir el robo de las tapas. The maintenance of infrastructure elements such as the wiring of communications systems, power transmission and distribution networks, gas networks, aqueduct and sewage networks located underground requires step boxes and intermediate chambers, which become at critical points for the security of these networks. In addition to preventing unauthorized access to underground networks, this type of device seeks to prevent theft of covers.

El solicitante ha detectado que el diseño de un dispositivo para seguridad de dichos puntos de acceso debe tener en cuenta consideraciones de facilidad de uso y apertura, sin las cuales no sería práctica su aplicación. En este sentido, los sistemas de bloqueo conocidos tienen el inconveniente de requerir una operación de cierre de accionamiento complicado, o en otros casos, de la realización de trabajos de adaptación en las cámaras. No obstante, la característica más deseada es dificultar la copia de las llaves de apertura. The applicant has detected that the design of a device for the security of said access points must take into account considerations of ease of use and openness, without which its application would not be practical. In this sense, known locking systems have the disadvantage of requiring a complicated operation of closing operation, or in other cases, of carrying out adaptation work in the chambers. However, the most desired feature is to make it difficult to copy the opening keys.
Siendo así, se requería desarrollar un dispositivo que permitiera transmitir movimiento a elementos giratorios lisos, tales como cabezas de tornillo y rotores para accionar pasadores, que tuviera la capacidad de adoptar configuraciones de tamaño diferentes, variando los diámetros de las superficies interiores en concordancia con los diámetros de los rotores, y que requiriera copas de apertura y cierre diferentes. Thus, it was required to develop a device that allowed to transmit movement to smooth rotating elements, such as screw heads and rotors to drive pins, that had the ability to adopt different size configurations, varying the diameters of the interior surfaces in accordance with the Rotor diameters, and requiring different opening and closing cups.

DESCRIPCION DETALLADA DE LA INVENCION DETAILED DESCRIPTION OF THE INVENTION
La presente invención proporciona un juego de copas, una para cierre y otra para apertura, para rotores de seguridad de cabeza lisa, para asegurar cámaras de los sistemas de comunicaciones, las redes de transmisión y distribución de energía, las redes de gas, las redes de acueducto y de aguas residuales contra accesos no deseados. Como ya se dijo antes, las copas de fricción aplican a dispositivos en los que la apertura o cierre requieren del giro de un tornillo o rotor. Como se ilustra en la figura 1 , las copas comprenden un cuerpo cilindrico externo (11) con paredes interiores excéntricas (111) conformadas por dos mitades de un cilindro, cortado por un plano que contienen el eje y desplazadas sobre el plano de corte en sentidos opuestos, de forma que los ejes de las dos mitades son paralelos.
Específicamente el cuerpo de la copa (1) comprende el cuerpo cilindrico (11), cuyas paredes interiores son excéntricas (1 11), sobre dichas paredes (1 11) se desplazan dos rodillos cilindricos (12), que son guiados por la canastilla ( 3). El anillo (14) mantiene el conjunto armado. The present invention provides a set of cups, one for closing and one for opening, for flathead security rotors, to secure cameras of communications systems, power transmission and distribution networks, gas networks, networks of aqueduct and wastewater against unwanted access. As mentioned before, the friction cups apply to devices in which the opening or closing requires the rotation of a screw or rotor. As illustrated in Figure 1, the cups comprise an external cylindrical body (11) with eccentric inner walls (111) formed by two halves of a cylinder, cut by a plane containing the axis and displaced on the cutting plane in directions opposite, so that the axes of the two halves are parallel. Specifically, the cup body (1) comprises the cylindrical body (11), whose inner walls are eccentric (11), on said walls (11) two cylindrical rollers (12) are moved, which are guided by the basket ( 3). The ring (14) keeps the assembly armed.
Como se puede apreciar en la figura 2, el rotor (2) está conformado por un cuerpo cilindrico (22) terminado en su extremo por un casquete esférico loco (21), cuya cabeza tiene un diámetro mayor que el diámetro del cilindro (22), de forma tal que el rotor no pueda ser girado mediante la colocación de un tubo forzado sobre ellos, en cuyo caso solo se transmitiría el giro al casquete esférico (21). As can be seen in Figure 2, the rotor (2) is made up of a cylindrical body (22) terminated at its end by a spherical idler cap (21), whose head has a diameter greater than the diameter of the cylinder (22) , so that the rotor cannot be turned by placing a forced tube on them, in which case only the rotation would be transmitted to the spherical cap (21).
El casquete esférico (21) termina en una cabeza lisa (211) y se asegura dentro del alojamiento (221) del cilindro (22) mediante el anillo de retención SEAGER (23). El tomillo se completa con el espárrago (24), al cual se le aplica un punto de soldadura para que permanezca armado. The spherical cap (21) ends in a smooth head (211) and is secured inside the housing (221) of the cylinder (22) by the SEAGER retaining ring (23). The thyme is completed with the stud (24), to which a welding point is applied so that it remains armed.
En la realización de la invención el cuerpo de la copa (1), sobre las paredes interiores que son excéntricas (111 ), se desplazan dos rodillos cilindricos (12) que son guiados por la canastilla (13). El anillo (14) mantiene el conjunto armado. In the embodiment of the invention the body of the cup (1), on the inner walls that are eccentric (111), two cylindrical rollers (12) that are guided by the basket (13) are moved. The ring (14) keeps the assembly armed.
Al colocar la copa en la cabeza del tornillo y girarla en el sentido que muestra la figura 1 , la canastilla (13) tiende a mantenerse inmóvil, haciendo que los rodillos (12) rueden sobre las paredes excéntricas (1 11) de la copa y que la distancia radial entre ambos rodillos se reduzca apretándolos contra la cabeza lisa del rotor, específicamente contra el cilindro (22), a la que arrastra por la fricción en el sentido de rotación de la copa (1), imprimiendo el movimiento de
giro necesario para aflojarlo, lo que permite abrir la tapa. By placing the cup on the screw head and turning it in the direction shown in Figure 1, the basket (13) tends to remain motionless, causing the rollers (12) to roll over the eccentric walls (11 11) of the cup and that the radial distance between both rollers be reduced by pressing them against the smooth head of the rotor, specifically against the cylinder (22), which is dragged by friction in the direction of rotation of the cup (1), printing the movement of rotation needed to loosen it, allowing the lid to open.
Al girar la copa en sentido contrario, los rodillos (12) ruedan sobre las superficies excéntricas (111 ) y se puede soltar la copa. By rotating the cup in the opposite direction, the rollers (12) roll on the eccentric surfaces (111) and the cup can be released.
Para ilustrar la forma como interactúan la copa (1) y el rotor (2) que constituyen el sistema de seguridad de la invención, se presentan las figura 3 y 4. La primera de ellas muestra una copa colocada en la cabeza de un rotor, en posición neutra, esto es, antes de iniciar el giro de la copa. Como se puede observar en dicha figura 3, los rodillos (12) se encuentran separados del flanco del cilindro del tornillo y no transmiten movimiento. To illustrate the way in which the cup (1) and the rotor (2) that constitute the safety system of the invention interact, figures 3 and 4 are presented. The first one shows a cup placed in the head of a rotor, in neutral position, that is, before starting the rotation of the cup. As can be seen in said figure 3, the rollers (12) are separated from the flank of the screw cylinder and do not transmit movement.
Por su parte, la figura 4 ilustra una copa (1) colocada en la cabeza de un rotor (2), cuando ya los rodillos (12) se han desplazado sobre las superficies interiores y excéntricas (111 ) de la copa (1) y comienzan a ejercer presión sobre el cilindro (22) del rotor (2) y transmiten movimiento para lograr que el rotor gire. On the other hand, Figure 4 illustrates a cup (1) placed on the head of a rotor (2), when the rollers (12) have already moved on the inner and eccentric surfaces (111) of the cup (1) and they begin to exert pressure on the cylinder (22) of the rotor (2) and transmit movement to make the rotor rotate.
Finalmente, la figura 5 representa un corte transversal de una copa de apertura (1A) y de una copa de cierre (1 B), respectivamente. Estas figuras son vistas desde el lado abierto de las copas de apertura y de cierre, y en ellas se observa el sentido invertido que tienen entre si las superficies interiores excéntricas (111). En una modalidad de la invención, cuando los rotores son del tipo en que la posición de cierre es mantenida por una carga de resorte, la copa de cierre no es necesaria.
Finally, Figure 5 represents a cross-section of an opening cup (1A) and a closing cup (1 B), respectively. These figures are seen from the open side of the opening and closing cups, and in them the inverted direction between the eccentric interior surfaces (111) is observed. In one embodiment of the invention, when the rotors are of the type in which the closing position is maintained by a spring load, the closing cup is not necessary.
