    Self-locking knot for deployable structures that allows the turning movement of the bars (1) connected to it while the structure is being deployed. When the bars reach the deployment position, the knot automatically blocks the rotation movement of each of them, preventing folding, so that manual intervention in each node is not necessary. The deployment and automatic blocking of the movement of each bar can occur independently of the other bars connected to the node, a fundamental aspect for certain deployable structures. The invention includes an elastic element (9) that acts by forcing the movement of the blocking pieces (8) of the bars and as a retaining element to prevent the movement of said pieces once the movement of the bars has been blocked. The elastic element can be deactivated by turning to unblock the movement of one or more bars. (Machine-translation by Google Translate, not legally binding)

    AUTOBLOCABLE KNOT FOR FOLDING STRUCTURES Field of the Invention
    The invention belongs to the construction sector, and specifically to the field of building structures. More specifically, the invention is included in the technical field of deployable roof structures.
    The present invention relates to a self-locking knot for deployable structures. Said knot allows the movement of rotation of the bars connected to it while the structure is unfolding. When each of the bars reaches the deployment position, the knot automatically blocks the turning movement of each of them. Background of the invention
    The nodes of a deployable structure must allow the movement of the bars connected to them to facilitate deployment. Also, when the structure has been deployed, it must be fixed, preventing folding. This can be achieved, for example, by connecting to the structure older bars in the deployed position, not present during the deployment phase, which complicates the process and requires labor, or, blocking the movement of the bars in some of its knots. When the blocking of the movement of bars in the nodes is used, this is usually occurring manually, being necessary to intervene in each of the nodes that are intended to block.
    There are several patents of knots for deployable structures, described for example in US4627210, US4280521 and US4838003, which allow the rotation of the bars connected to the knot but do not block their movement. There is also some example of a knot that only limits the opening of the bars to a certain angle but does not block their movement, such as the one included in US7712261. On the other hand, there are nodes for deployable structures that it is necessary to manually block after deployment such as the one collected in US4473986 or that do not allow independent automatic locking of each bar as it reaches the deployment position.
    There are deployable structures in which, due to their morphology, the deployment of the bars that connect to the node does not occur at the same time, that is, some bars deploy before others.
    It was therefore desirable a self-locking knot for deployable structures that facilitates the deployment and subsequent blocking of these avoiding the inconveniences of the prior art systems.

    Description of the invention
    The present invention aims at a self-locking knot for deployable structures, which allows the automatic blocking of the movement of each bar when it reaches the deployment position, regardless of whether the deployment of all bars connected to the node occurs simultaneously or not. . This aspect is essential for certain deployable structures. The blocking of the movement of each of the bars in the node is automatic and, therefore, manual intervention in the node is not necessary to achieve said blockage.
    The knot is formed by a core that can be constituted by a single piece or be formed by the union of sheets, sections of laminated profiles, castings or other elements. The end of each of the bars that connects to the node is connected to said core by means of a pin. Said pin allows the independent rotation movement of each of the bars and, therefore, the deployment of the structure. To this core can undertake one or more bars. To the core of the knot is also connected by a pin an independent locking piece for each bar that attaches to the knot. This piece is responsible for blocking the movement of the bar when it is deployed. The axis of the bar pin and the axis of the pin of its locking piece are parallel. The knot has an elastic element that forces the locking piece to adopt its blocking position and helps maintain that position in time.
    Brief description of the drawings
    To facilitate the understanding of the invention, drawings are attached in which, by way of illustration but not limitation, an embodiment of a knot constituted according to the invention is presented. In the drawings:
    - Figure 1 shows in axonometry the knot with the bars in the folded position. -Figure 2 shows in axonometry the node with the bars in an intermediate position of the deployment. -Figure 3 shows in axonometry the node in an intermediate position of the deployment prior to its block.
    - Figure 4 shows in axonometry the knot with the bars in the deployed position, with their movement already blocked by the blocking pieces.
    - Figure 5 shows in axonometry the deployment of a single bar in the moment prior to its blockage. -Figure 6 shows in axonometry the knot, with the elastic element rotated in such a way that it allows the manual release of the movement of the bars. -Figure 7 shows a possible exploded view of the knot. Detailed description of one embodiment
    In figures 1, 2, 3, 4, 5, 6 and 7 a node is shown to which four bars 1 constituted according to the invention are connected. Said knot is composed of a core formed by two angular plates 2 and four 3. Said and angular plates are connected to each other by means of screws 4. The ends of the bars 5 are connected to the core of the node by means of pins 6, which allow the movement of deployment of the same. The locking pieces 8 that block the movement of the bars in the deployment position are also connected to the core of the node 7, as can be seen in figures 3 and 4. Said blocking occurs when each locking piece is engaged. 8 at the end of each bar
    5. The knot has an elastic element constituted by a cruciform elastic plate 9 that acts to help the blocking pieces in their movement and as a retention element that prevents said pieces from moving from their position once they have blocked the movement of the bars. Said elastic plate 9 is connected to the core of the node by means of an element 10 that allows the rotation of the same in its plane, so that the sheet can be manually moved from the vertical of the locking pieces to proceed to the unlocking of the movement of a
    or several bars, as seen in figure 6. In figure 5 it can be seen that the deployment of the bars that rush to the knot does not have to occur at the same time.
