Zusammenfassung: | As from a conventional semi-hinge fixed to the frame, a complementary door fixing semi-hinge having, emerging perpendicularly from its base plate (1), a slide (3) destined to be housed in a blind hole on the door edge, a slide which is closed by its free end by means of a lid (12) and having a pair of opposite longitudinal guides (4), in which respective sets of balls have been fitted for the sliding of a runner (8), provided with complementary guides (4') for the mentioned set of balls and which is an elbowed extension of an arm (9) finishing in the bushing (10) or hinge itself, across which this semi-hinge is articulated to the semi-hinge fixed to the frame. Complementarily, slide (3) and runner (8) define a cylindrical housing (5-5') in which a spring (7) is housed, which in the case of the upper hinge tends to press the leaf against the frame and in the case of the lower hinge, tends to separate these components.
Pernio de seguridad. A partir de un semi-pernio convencional de fijación al marco, el semi-pernio complementario de fijación a la puerta cuenta, emergiendo perpendicularmente de su placa base (1), con una deslizadera (3) destinada a alojarse en un orificio ciego del borde de la puerta, deslizadera que se cierra por su extremidad libre mediante una tapa (12) y que cuenta con una pareja de guías longitudinales (4), enfrentadas, en las que se establecen respectivos juegos de bolas para deslizamiento de un patín (8), provisto de guías complementarias (4'') para los citados juegos de bolas y que es prolongación acodada de un brazo (9) que se remata en el casquillo (10) o pernio propiamente dicho a través del que este semi-pernio se une articuladamente al semi- pernio fijado al marco. Complementariamente deslizadera (3) y patín (8) definen un alojamiento cilíndrico (5-5'') en el que se aloja un muelle (7) que en el caso de la bisagra superior tiende a presionar la hoja contra el marco y que en el caso de la bisagra inferior tiende a separar estos elementos. |
