Sliding gates— Patent № 159849

Sliding gates comprise a supporting structure, two roller supports mounted on the supporting structure, at least one of which is made with the possibility of adjusting its position in the vertical and horizontal planes, a movable enclosing frame structure, which has an opening and a counterweight part and is mounted on the roller supports by means of a guide located in its lower part with the possibility of horizontal movement in the directions of extension and closing, limiters of the movement of the enclosing frame structure in the direction of closing and a roller limiter of lateral vibrations of the enclosing frame structure. In this case, the supporting structure comprises the first, second and third arched posts, which are formed by beams located in planes perpendicular to the enclosing frame structure, and the said arched posts are arranged sequentially in the direction of extension of the enclosing frame structure, which in the closed state is placed in the openings of these arched posts. The movement limiters of the enclosing frame structure are installed in the upper and lower parts of the opening of the first arched post, and the roller limiter of lateral oscillations of the enclosing frame structure is installed in the upper part of the opening of the second arched post. The second and third arched posts are connected to each other by at least three beams to form an integral frame part of the supporting structure, where two of the specified beams are located horizontally and connect the lower parts of the vertical beams of the second and third arched posts, in addition, the specified beams connecting the arched posts are located in planes parallel to the enclosing frame structure. At least one of these beams connects the upper parts of the specified arched posts, and the length of the frame part of the supporting structure is at least 1/3 of the length of the enclosing frame structure. The supporting structure additionally comprises first, second and third supporting elements with a horizontal surface, with a corresponding arched stand installed on each of the individual supporting elements, and roller supports installed on the second and third supporting elements in the openings of the corresponding arched stands.
