DEVICE FOR COLLAPSING TOWERS IN MOVABLE STRUCTURES

摘要

The device is specially designed to facilitate the collapsing of towers (4) in movable structures that are frequently assembled and dismantled, such as, for example, in the field of the staging of events. The invention consists in establishing, on the tower (4), a fixed, lower base (2) of scant height, which is securely connected to the general structure (1) on which the tower (4) is to be raised, whilst the remaining, principal sector of said tower (4) is connected to the base (2) via a hinging shaft (3), there being established, between the principal sector (4) of the tower and the fixed structure (1), a connecting rod (6) joined in an articulated manner to both elements, which together with those elements and with the base (2) forms a deformable quadrilateral. A hydraulic or pneumatic piston (7) extends between the connecting rod (6) and the fixed structure (1) such that, in a retraction situation, it generates the collapsing of the principal sector (4) of the tower on the structure (1), whilst in a situation of maximum extension it positions said tower (4) vertically.
