Definitions

  • THIS INVENTION relates to space frame components and assemblies thereof wherein the space frame is defined by a plurality of generally tubular frame members having their ends connected to free ends of other frame members by means of suitable connector elements.
  • Space frames of the above general type are usually assembled to form quadripoids (ie. pyramids) coupled together to form a frame suitable for supporting a roof or the like and having an extended area in plan view.
  • quadripoids ie. pyramids
  • Such a space frame requires few or no columns to support the central region thereof and, thus, are employed where large areas of "column-free" space are required.
  • Such space frames have been made for many years and all have the common feature of having connector elements to which the free ends of a number of frame members can be attached in order to connect them together.
  • Such connector elements are not only required to connect co-planar frame members, but also, frame members extending at an incline to the plane which contains some of them to define the above mentioned quadripoids.
  • the frame members defining the quadripoids could be co-incedent with, or offset from, the co-planar frame members in plan view as may be required.
  • a space frame connector element comprising at least a first and second part whereof the first part is in the form of a. ring (which may be split) having angularly spaced holes in the wall thereof to receive co-planar fasteners associated with frame members, the second part has at least a convergent wall section provided with holes therethrough at suitably angularly spaced positions with the axes of the holes being at substantially right angles to the convergent wall sections in which they are located, co-operating formations on the two parts(and, in the case where the ring is split, for retaining the parts of the ring together,)and means for holding the two parts in fixed association with each other.
  • first part to be a ring shaped member split at diammetrically opposed positions on the periphery of the ring; for a third part to be provided and having formations co-operating with the end of the ring opposite the second part for maintaining the parts of the ring in association with each other; for the said third part to be identical to said second part with the convergent wall sections extending in the opposite direction; and for said' means for holding the parts together to be a fastener passing through the first, second and, where present, the third parts to clamp them together.
  • bolts be installed to extend from the interior of the connector outwardly in order to secure the ends of frame members having screw threaded nut formations fixed relative thereto.
  • Such bolts conveniently have the form of a grub screw with a knurled outer surface and hexagonal shaped socket head operable by means of a conventional Allen-key.
  • the splitting of the ring enables such an Allen-key to be employed on the socket of a bolt without too much inteference from the remainder of the ring even though there may only be little space available.
  • the element can be made so small that the peripheries of the heads of bolts passing through the holes in the second and where present, the third parts, co-operate with specially provided notches in the inner periphery of the ring in order firstly, to accommodate the heads, and, secondly to orientate the second and third parts angularly relative to the first part and the axis of the connector element.
  • the co-planar and quadripoid frame members may be of equal length there may be lugs formed on the outside surface of the ring where the frame members are connected thereto.
  • the whole connector element could be made to be substantially spherical in shape in the operative condition.
  • means be embodied within the connector for holding the head substantially in engagement with its adjacent surface surrounding the hole through which it extends.
  • Such means could take any suitable form and may, in fact, be in the form of specially manufactured and shaped inserts co-operating with the bolt heads and also, for example, a bolt passing through the connector element in order to secure the parts thereof together.
  • the bolts could be provided with a circumferentially extending groove in the surface thereof on the exterior of the connector element and a circlip and washer arrangement could be employed to maintain the bolts in position axially with respect to their holes.
  • a further alternative is to provide a suitable deformable sleeve, the ends of which are arranged to maintain the heads of the quadripoid bolts in position and the central region of which is adapted to deform outwardly as the bolt securing the parts of the connector element together is tightened.
  • This is a well known principle of circumferential expansion of an element.
  • the connector element comprises three parts, namely, a split ring 1 and two roughly conical shaped parts 2, one of which is adapted to be associated with each end of the ring 1.
  • the portions 3 of the ring are defined by diammetrically opposed cuts therein and each of the portions accommodates two symmetrically located holes 4 for receiving socket headed bolts 5 passing therethrough in co-planar manner.
  • the four bolts will extend in directions angularly spaced by 90° from each other.
  • the ring is provided with a rebate 6 at each end thereof in the outer end surface of the ring, this rebate defining a formation for co-operation with a encircling lip 7 of the adjacent conical part 2. These lips therefore maintain the parts of the ring in proper association with each other in use by co-operation with each of the rebated ends.
  • the outer surface of the ring is flattened as indicated by numeral 8 in the region of each hole 4 so that an end of a frame member can be clamped firmly up against such flattened surface.
  • the ring can be made extremely small as access by an Allen-key to the socket heads of the bolts can easily be achieved without interference.
  • the ring can be made so small that very little space exists between the bolt heads and the shank of a bolt used to secure the parts of the connector element together. This can be seen most clearly in Figs. 2 and 3. If, however, the ring is large enough, it need not be split at all.
  • each of these is provided with four holes 9 in the walls thereof so that four bolts 10 can be passed through these holes in a substantially "quadripoid" relationship relative to each other. That is to say that the.bolts will extend at approximately 45° to the plane in which the four bolts of the ring are located and will, in plan view. be offset from each other by 90°.
  • the heads 11 of these bolts will, when the ring is dimensioned as indicated above, generally foul the inner edge of the ring 1 and, this feature is employed to positively locate the conical parts relative to the ring part in certain fixed angular positions.
  • the inner edge of the ring part is recessed as indicated by numeral 12 with recesses adapted to co-operate with the round external surface of the head 11 of each of the bolts 10.
  • the recesses are orientated such that the bolts 10 can either, in plan view, be coincident with the bolts extending from the ring or can be offset angularly therefrom by 45°.
  • each cone member is flattened as indicated by numeral 13 and perforated with a hole 14 to receive a bolt 15 passing axially therethrough.
  • the bolts 5 or 10 associated with a part of the connector can be attached to an end 16 of a tubular frame member 17 (see Fig. 3) the end having, for this purpose, an internally screw threaded fitting 18 welded to the frame member.
  • each half of the ring shaped part can be attached to two frame members whilst each conical shaped part can be attached to four of such frame members.
  • fittings could be made to bear against the bolt 15 connecting the parts together and also against the heads of the socket headed bolts.
  • Such fittings could be somewhat deformable to ensure that the bolt heads are urged against the inner surface of the connector element to a desired extent.
  • a deformable sleeve arrangement of the type outlined above could be employed at which each end of the sleeve co-operates with the bolts 10 of a conical part of the connector element whilst the central region is adapted to bulge outwardly during tightening of the assembly bolt 15 to engage the heads of the bolts 5 associated with the ring.
  • the ring could, if necessary, be made as one piece or, indeed, could be made as three or more pieces.
  • the bolts could have conventional shaped heads but, again, this is disadvantageous from the point of view of manipulation of such heads, a socket being very much preferred.
  • the formations for locating the conical members in desired angular orientations relative to the ring could be of any other form and could, in fact, be formations specially provided on the conical members and ring.
  • the whole assembled connector element may be of a spherical shape.
  • the ring may have lugs on the outside to make up the shortfall.
  • a connector element and frame members made according to the invention will be very much superior in use to the prior art types of assemblies and, in addition, the manufacturing costs are low.
