    专利说明:

    The present invention relates to a connection system for elongated elements such as for example beams or the like.
    A non-limiting field of application for the invention is more particularly the manufacture of light structures such as, for example, a terrace support, a base of a construction such as a garden shed or the like, etc. . These structures are in particular wooden structures but the invention can also relate to metal structures (for example with aluminum tubular beams for example).
    Most often, the connection devices are designed to allow a connection of two elongated elements or to make a connection at right angles. These devices are then, for example, fishplates or brackets which are then used to connect two elements.
    The present invention therefore aims to provide a simple connection system which can effectively ensure the connection of two elongated elements (beams in particular) in several positions so as to have great modularity and great freedom of configuration.
    Another object of the invention is to provide a system which is easy to implement, if possible intuitive and preferably of a limited cost price.
    To this end, the present invention provides a connection system for elongated elements comprising:
    - a circular cylindrical axis, and
    - at least two connectors, each connector having:
    two fixing plates arranged opposite one another and connected to each other by a connecting portion which has a curved zone which can follow an external surface of the circular cylindrical axis.
    This system is advantageous because it is possible to position the connectors on the axis. They can then pivot around it. We then fix the elongated elements between the fixing plates of each connector. The axis then forms a knot between the elongated elements which can take up the forces exerted subsequently on these elements.
    The elements used can be simple. Thus, for example, it can be provided that each connector is made from a cut and folded sheet.
    Each plate is preferably a rectangular plate. Such a shape is easy to manufacture and then it is easy to handle.
    To ensure good rigidity in the system, provision is made for a connection portion preferably to include at least two strips of material connecting the two fixing plates.
    In a connection system with rectangular fixing plates connected by strips, it can be provided that the two fixing plates are symmetrical with respect to each other; that the strips of material connect a first edge of a fixing plate to a second edge of the other fixing plate, and that the added heights of the strips of material correspond to no more than a quarter of the length of the first edge.
    Advantageously, each plate has fixing holes of oblong shape.
    A connection system as described above may also include a plate with a diameter greater than the diameter of the circular cylindrical axis, the axis coming to bear on said plate. This tray can then also serve as support for the connectors mounted on the axis.
    To facilitate the mounting of a structure with a system as described above, the circular cylindrical axis is advantageously mounted on a foot whose height is adjustable.
    When the curved zone of the connecting portion is curved through 180 °, there is then a system allowing good guidance of the connectors on the axis and also having connectors that are easy to manufacture.
    Details and advantages of the present invention will become more apparent from the description which follows, given with reference to the appended schematic drawing in which:
    FIG. 1 is a view of a sheet cut out to make a first connector,
    FIG. 2 corresponds to FIG. 1 for a second connector,
    FIG. 3 is a perspective view of the first connector,
    FIG. 4 is a perspective view of the second connector,
    FIG. 5 is an exploded perspective view of two first connectors and two second connectors,
    FIG. 6 is a perspective view of an axis,
    FIG. 7 is a perspective view of a foot intended to support the axis of FIG. 6,
    FIG. 8 is a perspective view of the axis mounted on its foot, and
    Figure 9 shows the connectors of Figure 5 mounted on the assembly formed by the axis and the foot of Figure 8.
    Figure 1 shows a sheet cut before folding, this sheet being intended to form a first connector. It is, for example, a sheet of galvanized steel. This material is given by way of nonlimiting example. A metal is preferably used here, preferably steel for mechanical reasons, but for the production of lightly loaded structures, it is possible to use a light alloy, for example based on aluminum. The connector can also be made of rigid synthetic material.
    The sheet illustrated in Figure 1 is generally rectangular in shape and corresponds to a preferred embodiment of the present invention. This sheet has three parts: a first plate 2, a connecting part 4 and a second plate 6.
    The first plate 2 is here, in this preferred embodiment, a rectangular plate of height H and width C, its width being less than its height. We thus define for this first plate 2 two large edges 8 and two small edges 10. This first plate 2 has three oblong holes: a first oblong hole 12 extending parallel to the small edges 10 halfway up the first plate 2 and two oblong holes inclined 14 to 45 ° relative to the edges of the first plate and arranged symmetrically on either side of the first oblong hole 12.
    The second plate 6 is arranged symmetrically with the first plate 2 with respect to the connecting part 4. Thus for this second plate 6 we find two large edges 8 of length H and two small edges 10 of length C a first oblong hole 12 and two oblong oblique holes 14.
    The connecting part 4 is formed here of three strips 16 of length L and width hl. The strips 16 are strips of elongated rectangular shape and each strip 16 connects a large edge 8 of the first plate 2 to a large edge 8 of the second plate 6 by extending perpendicular to these edges.
    In this first sheet intended to form a connector, it is noted that a strip 16 has a longitudinal edge lying in the extension of a small edge 10 of the first plate 2 and of a small edge 10 of the second plate 6.
    The strips 6 are regularly spaced along the large edges 8 of each plate. A height h2 separates two neighboring bands. In the embodiment described here, the following relationships are provided:
    h2 = 3 * hl
    H = 3 * (hl + h2)
    This means first of all that three bands similar to a band 16 can be accommodated between two bands of the connecting part 4.
    Then, the second relation above indicates that one can have three sets of four strips 16 on a plate height (first plate 2 or second plate 6).
    These relationships correspond to a preferred embodiment but which can be adapted as a function of the external constraints encountered as will emerge from the following description.
    Figure 2 illustrates another sheet that looks a lot like the sheet in Figure
    1. Here we find a first plate 2 and a second plate 6 identical to those of Figure 1 and which therefore use the same references (also for the other elements). There is also a connecting part 4 with three strips 16. The difference between the sheet of Figure 1 and that of Figure 2 is that the strips 16 are arranged differently from the plates. Here, no strip is arranged so that a longitudinal edge of a strip comes to extend a small edge of a plate. Relative to the sheet of Figure 1, the strips 16 are offset by a height corresponding to 2 * hl down "(according to the orientation of the figures).
    The dimensions here remain unchanged. The values of H, L hl and h2 correspond to the same values in FIG. 1 and in FIG. 2.
    FIG. 3 corresponds to a first connector 22 produced from a sheet of FIG. 1. Here a folding has been carried out so as to bring the first plate 2 opposite the second plate 6. The strips 16 are folded so as to form an arc of a circle over 180 ° in diameter D. In the connector thus produced, each strip thus comprises a semicircle 18 and connecting tabs 20 rectilinear connecting the semi-circle 18 to the plates.
    FIG. 4 corresponds to a second connector 24 produced from a sheet of FIG. 2. Here too, the strips 16 have been folded in the same manner as explained with reference to FIG. 3. A connector is thus obtained with semi-circles 18 (and the fixing lugs 20) offset in height relative to the connector of FIG. 3.
    Figure 5 illustrates four connectors positioned opposite each other. The small edges 10 of all the plates (first plates 2 and second plates 6) are in two parallel planes. Two first connectors 22 are arranged opposite and two second connectors 24 are also arranged opposite. The first connectors 22 are offset by 90 ° relative to the second connectors 24. It is noted that two connectors arranged opposite are "inverted" so that their semicircles 18 are not at the same height. By bringing all the connectors illustrated in FIG. 5 together, their semicircles 18 can be nested one inside the other as illustrated in FIG. 9.
    When these connectors are assembled, they can be mounted on an axis as illustrated in Figure 9. Figures 6 to 8 show such an axis and a foot to support such an axis.
    Figure 6 shows an axis 26 which consists of a circular cylindrical tube. This tube is for example made of steel. The outside diameter of this tube is chosen to receive the semicircles 18 (or conversely, the semicircles 18 are adapted to the diameter of the axis 26). Here, the diameter of the axis 26 is also equal to D which corresponds to the spacing between the first plate and the second plate of the connector and to the inside radius of curvature of each semicircle 18.
    FIG. 7 shows a foot 28 intended to support the axis 26. This foot 28 comprises a plate 30 from which a threaded rod 32 extends perpendicularly. A nut 34 is mounted on the threaded rod 32. A plate 36 whose diameter is slightly greater than D is secured to the nut 34.
    As illustrated in FIG. 8, the axis comes to take place on the plate 36. For greater stability, it is possible to provide that the axis 26 has a bottom closing an end face of the tube constituting the axis, said base with a hexagonal cutout corresponding to the external contour of the nut 34.
    Note here that the foot is an adjustable foot thanks to the cooperation of the threaded rod 32 with the nut 34. If the axis 26 is provided with a bottom as suggested above, the position of the axis 26 can be adjusted by rotating it around the threaded rod 32.
    You can position one to four connectors on axis 26. Few structures make more than four beams or the like converge towards the same point.
    However, it is possible to modify the connecting part of the connectors in order to be able to put more than four connectors on the same axis 26.
    The plate 36, of diameter larger than the axis 26, forms a stop for a first connector 22 (alone or from a set of connectors) which is positioned on the axis 26. The connectors are all of first assembled and then fitted on the axis 26. They are then supported by the plate 36.
    Other means can be provided to act as a stop for the connectors: one can form a flange outwards on one end of the axis 26, or else one can come to weld either a ring or a few specific stops on the axis. , a part can also be crimped on axis 26, ... many solutions exist.
    Once the connectors on axis 26, it is possible to rotate them to make them take the desired position. Once positioned, beams or the like take place each time between a first plate 2 and a second plate 6 of each connector and be fixed by screwing using the oblong holes made in these plates.
    In an alternative embodiment, provision can be made to connect each time two small edges 10 of two facing plates by a small support (not shown) which would support the beam or the like during its fixing by screwing. We can also provide a small ledge folded towards the other plate to support a beam, a plank, ...
    The invention thus allows the assembly of several building elements together with determined angles and any surface.
    The proposed system is simple since it is made from machined sheets, folded and drilled right through holes allowing the fixing of beams, planks or the like by screwing or bolting, hinging or not around a metal axis cylindrical adjustable and can be declined in different heights.
    The applications of this system relate to a type of light construction such as terraces or foundations for garden sheds which usually require pre-molding of a concrete slab or the laying of rigid elements such as concrete beams, concrete blocks, etc. ..
    Note that this device is only composed of two different and reversible connectors, associated with a cylindrical foot element.
    The fixing of these connectors on the planks ensures the solidarity of the assembly thus formed.
    Such a system can be available in several versions of different size and weight to meet the resistance sought.
    To summarize, these are metal connectors allowing the assembly of beams, planks or the like, preferably but not exclusively of wood, used for the realization of terraces, bases of constructions of the type of garden sheds, chalets, above-ground floors, railings, balustrades, ...
    The assembly of the various connectors between them on the cylindrical axis and its base allows great freedom of configuration with variable and adjustable angles.
    The present invention is not limited to the preferred embodiment described above and to the variant embodiments mentioned. It also relates to variants within the reach of the skilled person within the scope of the claims below.
    If the central axis must have a circular shape, the skilled person will understand that the various elements of rectangular shape are given for illustrative purposes only. It is a preferred form because it is easier to carry out with conventional tools. The number of bands of the connecting parts can of course be modified without departing from the scope of the invention. The preferred embodiment provides for two separate connectors, but a greater number of connectors can be provided, for example all of the connectors on one axis can be separate from each other.
    Many types of feet can be used, such as, for example, plots made of synthetic material, or concrete, already used to make terraces.
    In the example given, the curved parts are semicircles. They could be curved over less than 180 ° and also up to 360 ° (the plates could be fixed on rings but this embodiment cannot a priori be produced by cutting and bending a sheet).
    We can also consider having plastic parts obtained by molding.
