    [0002] Attachable connection node for deployable structures.
    [0003]
    [0004] Field of the Invention
    [0005]
    [0006] The present invention belongs to the field of construction and light and / or folding structures, and more specifically to the field of connection nodes for deployable structures, and in particular connection nodes for three-dimensional Tensegrity deployable structures.
    [0007]
    [0008] Background of the invention
    [0009]
    [0010] In the field of construction, articulated or lattice structures are reticular structures of straight bars interconnected in nodes forming flat triangles (in flat lattices) or three-dimensional pyramids (in spatial lattices), so that in each node several bars can converge .
    [0011]
    [0012] Within the latter, there are the spatial structures, composed of linear elements joined in such a way that the forces are transferred in a three-dimensional way. They can take any type of both flat and curved. Its elements are prefabricated and do not require for the assembly of joining means other than purely mechanical ones (that is, it is not necessary to weld them on site, for example).
    [0013]
    [0014] Classified within the spatial structures are those of Tensegrity, which use compressed isolated components that are within a continuous tractional network, so that the compression members (usually bars) do not touch each other and are only joined by means of tensioned elements (usually cables) which are those that spatially delimit said system, which is in equilibrium and is stable by itself.
    [0015]
    [0016] Any of these types of construction (two-dimensional or three-dimensional) may be capable of encompassing deployable variants. The deployable structures allow the system to move from an extended configuration (in service) to a compact configuration through a folding process. This folded state is the most appropriate for storage or transport to other locations where they can be deployed and put back into service. In all these cases, the bars that make up the structure are joined by knots, which are extremely important, since they are the ones that ensure the stability of the joints and the functionality of the system. There are great diversity of nodes (spherical, cylindrical, prismatic, flat, etc.) but few of them allow the folding and unfolding of the structure.
    [0017]
    [0018] More particular are the nodes of the Tensegrity structures, because in addition to joining bars they have to anchor the prestressed cables that make up and stabilize the system. In any case, it is important to highlight that these cables are essential in Tensegrity structures, but are not exclusive to them; that is, there are other types of structures that also use them.
    [0019]
    [0020] In general, a Tensegrity mesh can be classified by its class (k), where k is the number of compression elements (bars) that converge in a knot. A large part of the existing knots are currently designed only for Tensegrity structures of class 1 (k = 1), that is, those in which each node reaches a maximum of one bar. However, these nodes are not valid for structures of class 2 or higher (k> 2), in the that there are at least 2 bars that converge in each knot. Examples of these class 1 nodes are detailed in the following documents:

    [0058]
    [0059] In these situations with more than one bar coming together at each node ([8], [9], [10], [11], [12], [13], [14], [15], [16], [ 17], [18]), if the structure is to be folded and easily deployed, it is necessary to design the knots in such a way as to allow a relative rotation of said rods with respect to the knot. However, this is not possible in [10], [11] and [12].
    [0060]
    [0061] On the other hand, an additional disadvantage of all these nodes of class k> 1, with the exception of the one described in [17], is that the directions of the cables that converge in them are not very versatile and are quite conditioned. In addition, among all these nodes, some of them are very limited because they can fix few cables (cases [8], [9], [14], [16]). Another important limitation of the node described in [8] is that it needs a minimum of 3 bars to be stable.
    [0062]
    [0063] In addition, virtually none of the nodes with more than one bar converging on it described in the state of the art, allows the cables to slide through it, so that the cable is guided but not gagged and thus allows it to run or slide inside the fastener. The only cases that contemplate this possibility are the nodes [13], [17] and [18]. [13] only allows one of the cables to be sliding, in only one direction, and not the rest of the cables that reach the node in the plane perpendicular to it. In addition, this knot [13] stands out for its great complexity, high weight, manufacturing difficulty and excessive price. In addition, none of the nodes [17] and [18] allow the upper sliding cables to form arbitrary angles in a versatile manner or the number of sliding cables to be high (of more than 3 cables, for example).
    [0064]
    [0065] Specifically, the node described in [17], the work of the inventors of the present invention, brings together two or more rods that can be rotated and folded in volume, allows receiving a plurality of cables from different directions and angles, allows said Cables can slide through the knot to facilitate the folding of the structure and is also lightweight, manageable, economical and easy to manufacture and assemble. However, this node [17], like many others described above, has a series of limitations that are set out below: it does not ensure that the arrangement of the bars, as they fold, form the same angle with the plane middle of the knot; it is difficult to attach horizontally to other nodes or attached bars, because its rectangular shape with protuberances at the ends does not achieve optimum compaction when the mesh is fully folded; once the structure is fully folded, there is no mechanism that fixes that position and prevents it from reopening involuntarily; there is no versatile solution for upper sliding cables to form arbitrary angles; it is not possible that the number of sliding cables is high (of more than 3 cables, for example).
    [0066] In short, in the state of the art there is no node that meets the main features of the node [17] and, additionally, allows the bars to always form the same angle with the middle plane of the connection, which ensures that, Once the structure is fully folded, the nodes easily attach and fix each other or to other bars, and allow the upper sliding cables, in large numbers (for example, more than two), to form arbitrary angles.
    [0067]
    [0068] Summary of the Invention

    [0134]
    [0135] In addition, the terms "approximately", "substantially", "around", "ones", etc. they should be understood as indicating values close to which these terms accompany, since due to calculation or measurement errors, it is impossible to achieve those values with total accuracy.
    [0136]
    [0137] In addition, continuous cables are understood to be those cables that are not anchored to the node of the invention, but that slide between the grooves and / or perforations of said node.
    [0138]
    [0139] In addition, discontinuous cables or non-continuous cables are understood as those cables that are anchored to the node of the invention by, for example, a carabiner or a shackle.
    [0140]
    [0141] The characteristics of the node of the invention, as well as the advantages derived therefrom, can be better understood with the following description, made with reference to the drawings listed above.
    [0142]
    [0143] The following preferred embodiments are provided by way of illustration, and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention.
    [0144]
    [0145] Next, the connection node for deployable structures of the invention is described, which is light, manageable, economical and simple to manufacture and assemble, and also allows 1) agglutinate two or four bars that can be rotated and folded in volume thereto, so that each bar forms the same angle as at least one of the other bars, with respect to the longitudinal axis of the knot; 2) be coupled to other nodes (with their corresponding bars) once the structure is fully folded, such that they easily bind together; 3) be fixed to other nodes, such that once coupled they do not involuntarily disengage and 4) that the upper sliding cables form arbitrary angles, said cables being perpendicular to the longitudinal axis of the node.
    [0146]
    [0147] Preferably, the deployable structures are spatial and Tensegrity, although not limited.
    [0148]
    [0149] Figures 1-9 show a scheme of different embodiments of the node of the invention (figures 1-5: class 2 and unfolded; figure 6: class 2 and folded; figure 7: class 4 and unfolded; figures 8-9: class 4 and folding). The present invention resolves the functional deficiencies found in the literature on knots of deployable structures and especially Tensegrity structures.
    [0150]
    [0151] The node of the invention is composed of the following elements:
    [0152]
    [0153] -A central core formed by a soul 11, 21, 31, 41, 51, 61, 71, 81, 91 and at least two lateral wings 12, 22, 32, 42, 52, 62, 72, 82, 92, of such that there are at least the same number of side wings 12, 22, 32, 42, 52, 62, 72, 82, 92 as of bars 13, 23, 33, 43, 53, 63, 73, 83, 93.
    [0154] The core 11, 21, 31, 41, 51, 61, 71, 81, 91 is substantially flat in a preferred embodiment, and has a section with 1) at least one inwardly shaped side, for example concavely; and 2) at least one lateral shaped outward, for example convex shaped. This configuration allows the coupling between two central cores or between a central core and a bar, if the knots are at a different level, as shown in Figures 10-16.
    [0155]
    [0156] Preferably, each side wing 12, 22, 32, 42, 52, 62, 72, 82, 92 is substantially flat and substantially perpendicular to the core 11,21,31,41,51, 61, 71, 81, 91, attached to it by, for example, welded, folded, tongue and groove, extruded or screwed. Furthermore, preferably each side wing 12, 22, 32, 42, 52, 62, 72, 82, 92 is positioned substantially parallel to another side wing 12, 22, 32, 42, 52, 62, 72, 82, 92 , such that each pair of side wings 12, 22, 32,42, 52, 62, 72, 82, 92 facing each other brings together at least one bar 13, 23, 33,43, 53, 63, 73, 83, 93.
    [0157]
    [0158] In addition, once the node of the invention is installed and operative in a certain deployable structure, the core 11, 21, 31, 41, 51, 61, 71, 81, 91 is preferably positioned substantially horizontally, and the The space between the lateral wings 12, 22, 32, 42, 52, 62, 72, 82, 92 is located at a lower height than the soul 11, 21, 31, 41, 51, 61, 71, 81, 91.
    [0159]
    [0160] The lateral wings 12, 22, 32, 42, 52, 62, 72, 82, 92 have mechanical fixing perforations and cable perforations, configured to house mechanical fasteners 74, 84, 94 and wing cables 15, 25, 35, 45, 55, 65 respectively.
    [0161]
    [0162] Each mechanical fastener 74, 84, 94 is positioned through two mechanical fastening perforations of two facing side wings, such that each mechanical fastening bore is located on a lateral wing 12, 22, 32, 42, 52, 62, 72, 82 92 different and such that said two mechanical fixing perforations are aligned on the same axis, this being perpendicular to the longitudinal axis of the node of the invention. In this way, each mechanical fixing piece 74, 84.

    [0233] Each wing cable passes through two cable perforations of the two lateral wings, such that each cable perforation is in a different lateral wing. In this case, the two cable perforations are not aligned on a given axis.
    [0234]
    [0235] -Two mechanical fixings configured to join the two bars to the central core. That is to say, each mechanical fixation goes through a first mechanical fixing perforation of a lateral wing, the perforation of a bar and a second mechanical fixing perforation of the other lateral wing, such that said three perforations (the two mechanical fixing perforations of the wings facing sides and the perforation of the bar) are aligned on the same axis, this being perpendicular to the longitudinal axis of the node of the invention. That is, each mechanical fixation crosses a single bar. In this way, each piece of mechanical fixation, once installed, is placed parallel to the plane that contains the soul and with its two ends outside the space formed between the two side wings facing each other.
    [0236]
    [0237] Said mechanical fixings are cylindrical, thus allowing the rotation of the bar they pass through and, in addition, they are thyme with eyes. In addition, in the ring that forms the head of said fixation, cables with different orientations are joined.
    [0238]
    [0239] Each mechanical fixation has a section of thickness less than the perforation of the bar that crosses them. This clearance allows the rotation between the mechanical fixation and the bar.
    [0240] -Two female fixings configured to prevent mechanical fixings from leaving their housing.
    [0241]
    [0242] -A guide eye connection, cylindrical section, perpendicular to the plane containing the soul, configured to join a mechanical stop, such that one of the elements is male (the mechanical stop) and crosses the perforation of the soul and the remaining female ( the guide eye bolt joint), and fix a cable tie between them. The guide eye connection ends with a ring located at the opposite end where the cable tie connector is located, such that said guide eye connection allows various axial cables to be received in its eye. The guide eye bolt joint comprises an opening along its longitudinal axis, configured to allow the displacement of a sliding link, and consequently of the two plates attached to the link. This displacement allows the folding and unfolding of the node of the invention.
    [0243]
    [0244] -A sliding link, inserted into the opening of the guide eye joint, configured to connect the ends of the two plates, and ensure that the two bars form the same angle with respect to the longitudinal axis of the knot.
    [0245]
    [0246] -Two plates configured to join the bars (through a pin) to the sliding link.
    [0247]
    [0248] - A cable clamp connector, of cylindrical section, with an opening configured to allow its clamping by the guide eye joint and the mechanical stop, such that said cable clamp is placed in contact with the soul surface furthest from the mechanical fasteners, and such that it comprises three overlapping pieces.
    [0249]
    [0250] The intermediate piece comprises two cable glands, each of them located on a different face. The upper and lower parts comprise a single cable gland, such that a) the groove of the upper part and one of the grooves of the intermediate part and b) the groove of the lower part and the remaining groove of the intermediate part are facing each other. In this exemplary embodiment, the grooves of the intermediate overlay form an angle of 60 ° to each other, allowing the cables that are housed there to form that same angle.
    [0251]
    [0252] -A mechanical stop located at the end of the cable tie that is not in contact with the core, and that is configured to join the guide eye connection and pinch the cable tie connector, preventing the radial cables from slipping out of the grooves and, additionally, gagging said cables avoiding their sliding along the longitudinal axis of the cable tie.
    [0253]
    [0254] In this example, the material of each element included in the node of the invention (central core, mechanical fasteners, female fasteners, guide eye connection, cable ties, plates, sliding link and mechanical stop) is steel.
