Definitions

  • the invention relates to a space framework with connecting elements having node elements, which consist of releasably connectable, annular bodies and whose sheathing is approximately spherical or polyhedral, and in particular tubular and / or rod-shaped connecting pieces, which are connected to the connecting elements of the spaced-apart node elements , for example, can be detachably connected by means of screw connections.
  • node elements consist of releasably connectable, annular bodies and whose sheathing is approximately spherical or polyhedral, and in particular tubular and / or rod-shaped connecting pieces, which are connected to the connecting elements of the spaced-apart node elements , for example, can be detachably connected by means of screw connections.
  • a knot element is known (GB-A 1 283 025), which consists of two octagonal, ring-shaped bodies.
  • the two annular bodies form a uniform octagon, so that the radial distance of the outer connection surfaces from the center of the node element is not the same.
  • the effort involved in creating a space framework within the required connecting rods becomes more complex.
  • the two annular bodies are deformed, so that the known node element is not dimensionally stable.
  • a knot element is also known (FR-A 2 471 455, FIG. 3) which consists of three rings which have different diameters and are arranged on an axis at an acute angle to one another. There is a center distance between the individual rings so that there is neither a positive nor a non-positive connection between the rings.
  • the connection points of different rings have different radial distances from the center of the node element, so that the connecting rods leading to adjacent node elements must have correspondingly different lengths.
  • the invention has for its object to design a space framework of the type mentioned so that its node elements allow connection options in the three mutually perpendicular room levels and that rod-shaped connectors with the same length can be used.
  • the node elements each consist of three annular bodies concentrically arranged at right angles to one another, which determine different connection levels with the same number of connection elements
  • the node elements have an inner body which is arranged in a central body and have an outer body , in which the middle body is arranged with the inner body, the inner body is connected with the middle and with the outer body on the inside, while the middle body communicates with the inside body on the outside and with the outside body on the inside, and that the radial distance of the connection points of the annular bodies for the connecting pieces leading to the other node elements from the center of the node element is the same.
  • connection points of the annular bodies are at the same distance from the center point of the node element, connecting pieces of uniform length are inevitably produced in the space framework.
  • the outer and inner outline of the body is a polygon, preferably an octagon.
  • the node elements are designed such that the outer body is a regular octagon, the diagonally opposite sides of which are each arranged at a clear distance of x (cm), that the middle body except for two diagonally opposite sides whose outer width across flats is x (cm) has essentially the same shape as the outer body and that the inner body has essentially the same shape as the middle body except for two diagonally opposite sides whose outer width across flats is x (cm) has, where these two sides are perpendicular to the sides of the middle body, the outer key width is already x (cm).
  • These node elements offer evenly distributed connection options for connecting pieces in all three mutually perpendicular planes.
  • the connecting elements are designed as radially extending bores which are evenly distributed over the circumference of the body, which provides for a further measure of the invention, then the force distribution within the node element is particularly good since the forces compensate each other.
  • the node element cannot be deformed even if the bodies consist of relatively thin-walled rings.
  • node elements the bodies of which consist, for example, of circular rings
  • the desired positive and non-positive engagement can be achieved in that the connecting parts of the bodies which are connected to one another have recesses of complementary shape.
  • bodies consist of elastic material, as is provided in a further expedient measure of the invention, the assembly of individual node elements can be carried out particularly easily and quickly.
  • the connecting elements are tabs or eyes, whereby these measures could also be taken because the tabs or eyes have circular bores, the central axes of which run at right angles to the connecting plane in which the tabs or eyes are located.
  • the forces originating from the connecting pieces act evenly tangentially on the node elements. If, however, the connecting pieces are angled at right angles at their ends, the forces act radially again, so that they compensate each other.
  • the tabs or eyes can be attached either on the inside and between the connecting parts of the body or on the outside of the body.
  • the advantages achieved by the invention also consist in a substantial simplification of the production of the knot and rod elements, as well as in a noticeable simplification of the assembly technology. If, for example, a node element with eighteen connecting elements (rod connection options) is to be produced, then only three differently designed rings with eight holes are required.
  • the rings can be produced in a simple manner as sections of an extruded profile (aluminum), an extruded profile (steel) or a cold or hot-formed hollow profile.
  • connecting elements having connecting elements, which consist of releasably connectable bodies and whose sheathing is approximately spherical or polyhedral.
  • the spatial framework also has tubular and / or rod-shaped connecting pieces, which can be detachably connected to the connecting elements of the spaced-apart node elements, for example by means of screw connections.
  • the node elements are formed from annular and concentrically arranged bodies. Each body defines a connection level with the same number of connection elements.
  • the node element 1 consists of three bodies 2, 3 and 4 arranged at right angles to one another, namely an inner body, which is arranged in a central body 3, and an outer body 2, in which the middle body 3 is arranged.
  • the three mentioned bodies 2, 3 and 4 each have the same number of connecting elements 5, 6 and 7.
  • each body 2, 3 and 4 has eight radially oriented connecting elements in the form of bores.
  • the bodies 2, 3 and 4 of the node element 1 are connected to one another in such a way that the inner body 4 is connected to the middle body 3 and to the outer body 2 on the outside, while the middle body 4 is connected to the inner body 4 on the inside and to the outside Body 2 is connected on the outside. This results in both a non-positive and a positive connection between the bodies 2, 3 and 4.
  • the connecting elements (bores) 5 and 6 are designed such that they are aligned with the adjacent bores of the other body. It is therefore possible to connect the connecting pieces 10, 11 (cf. FIG. 4) to the node element 1, for example by means of screws 12 and 13 of different lengths. The heads of the screws 12 and 13 are located in the interior of the node elements 1.
  • the bodies 2, 3 and 4 are designed so that their outer and inner outline is a polygon or circular.
  • the bodies 2, 3 and 4 have an octagonal outer and inner outline.
  • the outer body 2 is a regular octagon, the diagonally opposite sides 15 and 16 of which are arranged at a clear distance of x (cm) from one another (FIG. 5).
  • the middle body 3 has essentially the same shape as the outer body 2, with the exception of two diagonally opposite sides 18 and 19, whose outer width across flats is x (cm).
  • the outer width across flats of the diagonally opposite sides 20 and 21, of the inner body 4, which are connected to the middle body 3, and of the sides 22 and 23, which are connected to the outer body 2, is x (cm).
  • FIG. 2 in which the outer body 2 is shown in broken lines. It can also be seen that the bores 5 and 5 'have the same central axis.
  • FIG. 3 and 4 show that the node elements 1 can be connected with connecting pieces 10 and 11 or 10 'and 11', the diameters of which differ significantly.
  • connecting pieces 10 'and 11' with a large diameter, connecting supports 26, 27 tapering towards the node elements 1 are provided, with which an independence between the node elements 1 and the connecting pieces 10 ', 11' can be reached with regard to their diameter. This is particularly important if the user wants to have a space framework in which the node elements should not appear.
  • a space framework can also be produced in which the node elements are significantly larger than the diameter of the connecting pieces and serve, for example, as a lamp housing.
  • a node element 30 is shown with the required annular bodies 31,32,33.
  • the inner body 31 has recesses 36 on the outer circumference, which can be connected to the recesses 37 and 38 of complementary shape of the middle and outer bodies 32 and 33. Since these bodies are made of an elastic material, a positive and non-positive connection between the individual bodies can be easily produced by deformation.
  • Eyes 40, 41 and 42 are formed on the inner circumference of the bodies 31, 32 and 33 and serve as connecting elements of the node elements 30.
  • the eyes 51 and 52 are formed on the outer circumference of the bodies 55, 56 and 57.
  • the bodies 55, 56 and 57 have recesses 58, 59 and 60 through which a non-positive and positive connection can be produced between the bodies 55, 56 and 57.
  • node elements for the production of space frameworks or space grids.
  • the structural building blocks of these spatial grids are the basic bodies tetrahedron, hexahedron and octahedron.
  • eighteen connectors can be connected to the node element.
  • the node elements are composed of three different rings, which can be cut to length from three different tube profiles.
  • the three bodies (rings) of the node elements each standing at right angles to each other, form a spatial structure due to the screw connection with the rods, which is similar to a hollow sphere in terms of the transmission of tensile and compressive forces.
  • the width, the thickness and the diameter of the bodies (rings) are necessarily related, but are basically variable. That means: the definition of one of these three variables determines the dimensions of the other two bodies (rings).
  • the ring-shaped body can also be designed with a much larger ring thickness. It is then possible to introduce bearing shells as connecting elements which are accessible in a radially directed manner via inlet openings.
  • the connecting pieces then carry cylindrical bearing bodies which are connected to the connecting piece by a connecting web which is matched to the input opening.
  • the connecting pieces can then be inserted into the bearing shells transversely to the annular body and fixed therein by spreading the bearing body.
