Definitions

  • the invention has a significance for a great number of applications such as, for example, for support constructions which are made for transportable or movable containers, for scalioldings, for building purposes, for track installations, mast-like girders or towers, etc.
  • the invention particularly, relates to the construction of track- Ways, which are to be employed in connection with large containers, such as, book shelves, filing cabinets and the like.
  • the feature of the invention is the employment of individual constructional elements, or rod members, which may be interconnected in a simple manner at the location of their use without special aids, and may be similarly separated from each other for storage purposes.
  • the individual constructional elements comprise members, some of which have projecting tongue elements formed on a connecting side which interengage with recesses formed on similar elements to be connected thereto.
  • the elements may be assembled together in such a manner that they will be structurally rigid after erection, but in some instances, additional security means, such as screws, are advantageously provided.
  • additional security means such as screws, are advantageously provided.
  • the feature of the invention is that the individual structural elements are equipped with interengaging coupling parts which engage with one another in such a positive shape-locking fashion that the assembly is secured against external forces.
  • a security against forces acting in a longitudinal direction of the rods is achieved. It should be appreciated that security against longitudinal forces also includes the concept that the structure will be secure against forces acting obliquely, or which have a component force in the longitudinal direction.

  • the length and width of the support construction to be taken into consideration for the production are determined from the view point of the most extensive possible standardization. Sizes will be chosen so that for any particular installation, there will be a minimum number of different dimensions for the individual parts.
  • Such parts are particularly the longitudinal girders 5, the transverse rods 6 and the end pieces 7 and 10. Elements 4 are employed as covers between these parts.
  • intermeditae frames for insertion in the center between the frame assemblies 500 and 50b for example.
  • the intermediate frames would be identical with those illustrated in FIGS. 2 and 3 with the exception that the end pieces 7 and 10 would not be included, but there would be coupling elements arranged at each end.
  • the longitudinal elements 5 include the flat upper surface portion 5a, the side portion 5b and the intermediate, or rounded rails, 12.
  • the outer vertical portion 5b is provided with notched areas 18 in order to facilitate its insertion around tabs 19, which have hook areas 20 defined therein for interlocking, the longitudinal element 5 to the transverse element 6.
  • An inner vertical wall or leg 50 of the longitudinal member 5, 5 includes a tab portion 17 (FIG. 7) which fits into a recess 21 defined in the top base 6a of the trough-shaped transverse element 6.
  • the tab 17 may be bent to secure the elements 5 and 6 together.
  • the longitudinal girders 5 are placed, with the rail 12 outwardly, upon each end of the transverse rod 6 so that the tabs 17 engage in the slots 21, and are pressed downwardly until the notches 18, formed in the vertical portions 5b, fit into the notches of hooks 19.
  • the upwardly directed projections 20,0f the tabs 19 engage behind the outer side plate 5b so that a firm locking is provided against forces which act in a direction of the transverse member 6.
  • the right hand end portion 22 extends outwardly at the inner portion 50, with the rail 12 and the outer portion 5b being cut away in order to facilitate the reception of a transverse end piece of a type such as the type 7 or 10, indicated in FIGS. 2 and 3, respectively.
  • FIGS. 9 and 10 there is indicated the arrangementof the under-gripping coupling element 8 and the overgripping coupling element 9, respectively.
