Definitions

  • This invention relates to an improved coupling for forming load-bearing systems for work stations, particularly but not exclusively for offices.
  • the resultant structure should remain as solid as possible with time, without risk of deterioration due to the materials used.
  • the work station should be able to be formed without having to use special tools, and be adjustable in terms of layout at any moment by adding or removing components or changing the component combination.
  • the structures achieved should be able to be dismantled and separated into their individual components in the absence of welds, and be able to be rebuilt into different arrangements or recycled as raw material.
  • the load-bearing structure forming the work station should also be able to easily receive, at various points, service cable housing systems, partitioning systems (panels) and auxiliary worktops, if necessary of different height from the main worktop.
  • the general object of the present invention is to propose a coupling for forming load-bearing systems for work stations which adequately satisfies the aforelisted requirements.
  • a first embodiment of a coupling according to the invention is indicated overall by 10 and is structurally in the form of a central body 11 from which there extend, at 90°, two elastically expandable connectors 12, 13 intended for securely fixing a table leg 14 and, respectively, a section bar 15 for supporting and fixing a worktop 16 ( Figure 2).
  • the connector 12 comprises an expandable body of cylindrical socket shape comprising a plurality of slits 17 along generating lines of the skirt (three in number in the illustrated example), which extend into respective radial slits 18 provided in that endpiece 19 of said cylindrical socket distant from the central body 11.
  • the slits 17, 18 are suitably spaced apart, their purpose being to make the connector 12 relatively elastically yieldable.
  • a connector 12 of this type is described for example in EP-0467460, to which reference should be made if further clarification is required.
  • a second connector 13 consisting of an expandable body of generally parallelepiped form.
  • Said body 13 consists of a plurality of prismatic sectors 24 (three in number in the illustrated example) defined by three slits 25 converging substantially towards the axis of symmetry of the parallelepiped body.
  • the three prismatic sectors 24 are therefore relatively yieldable elastically and, similar to the connector 12, are expandable by means of a setscrew 26 with a polygonal head and tapering expansion point 27, which is screwed into a threaded hole 28 in one of the prismatic sectors 24 of the connector 13.
  • the setscrew 26 is bored axially to enable a screw 29 to pass for fixing the worktop 16.
  • the leg 14 and the section bar 15 comprise respective apertures 30, 31 through which, by means of a polygonal key 32 ( Figures 4, 5), the setscrews 21, 26 can be screwed into their respective threaded seats 20, 28, to cause the connectors 12, 13 to expand in all directions as shown by the arrows 33, 34 ( Figures 4, 5).
  • Figures 6-8 show a further possible embodiment of the invention in which two connectors 13 are combined with the connector 12, all arranged rigidly at 90° to each other.
  • Figures 9-11 show a third possible embodiment of a coupling according to the invention in which with the connector 12 there are combined two connectors 13 the angular positions of which can be adjusted one relative to the other.
  • a flange 35 on which, in the desired angular position, there are fixed a pair of counter-flanges 36 extending rigidly from one end of the respective connectors 13.
  • This fixing is achieved by a bolt 37 passing through holes 38, 39 in the flanges 36, 35.
  • Said bolt 37 is bored axially for the passage of a screw 40 used for fixing the worktop 16.
  • Figures 12-21 illustrate various embodiments of connection nodes into which a number of section bars 15 for supporting and fixing a worktop 16 converge.
  • connection node can comprise a central body 41 from which there radially extend a plurality (for example 2, 3 or 4) of expandable connectors 13 arranged in fixed angular positions.
  • Figures 19-21 show a connection node in which three connectors 13 can be mutually arranged in variable angular positions by using the system comprising a flange 35 and counter-flanges 36 previously described with reference to Figures 9-11 of the drawings.
  • section bars 15 can be supplied in the various commercially available lengths and cut by the work station manufacturer according to requirements.
  • Said section bars 15 can be used both for supporting service cables and for fixing partitioning panels and other accessories provided for the worktop.
