Definitions

  • the present invention relates to a turnbuckle spigot assembly particularly, although not exclusively, envisaged for use in coupling the ends of posts in trusses. This is especially useful in 4 post trusses (known as box or rectangular trusses), such as used to carry sound and lighting equipment for stage and theatre productions.
  • the turnbuckle spigot assembly of the present invention could be used to couple any two members together, such as, for example, two pipes or tubes.
  • the present invention relates to a turnbuckle spigot assembly, for internal endwise connection of the main members of two adjacent trusses for pulling the main members closely together in a secure and rigid manner so as to form the two trusses into a single truss span.
  • a typical connector is a rod with transverse holes at each end. Each of the holes receives a pin which also fits through a similar hole in a hollow end of a main member of the truss for fixing the end of the connector into the end of the main member.
  • a better solution is to use a turnbuckle adapted to have slack in it when in its loose position and which has only one thread for tightening.
  • the slack allows for easier connection to the ends of the main members, whilst the single thread gives increased leverage. Then the main members of two adjacent trusses can be connected together and brought into tight end to end arrangement even where the ends of the main members are not all in the same plane.
  • a turnbuckle spigot assembly for use in connecting two post members together, the turnbuckle spigot assembly comprising: a first end for attachment to one of the post members; a second end for attachment to the other post member; a drive member coupling the first end to the second end, the drive member being threadedly fixed to one of the said ends and free to move with respect to the other of the said ends; and, a turning element attached to the drive member for causing rotation of the drive member for driving the first and second ends together or apart for respectively tightening the post members together or loosening the post members.
  • the first end is a first spigot for receipt in one of the post members
  • the second end is a second spigot for receipt in the other one of the post members
  • the drive member has a head and a threaded shank, the head being received in the first spigot and the threaded shank being received in the second spigot so that rotation of the drive member with respect to the second spigot causes the second spigot to be drawn towards the head and driven away from the head depending upon the direction of said rotation.
  • the elongate drive member is a threaded bolt.
  • the main members are cylindrical tubes.
  • the turning element is fixed to the bolt by a key in a keyway.
  • the spigots are attached to the main members by radially disposed pins.
  • the turnbuckle spigot assembly also has an elongate pin located in the first spigot and spring biased towards the turning element which has an undulating groove in it so that the end of the pin rides up and down in the groove as the turning element is turned.
  • the bias of the spring holds the first and second spigots away from each other which making alignment with the holes in the main members easier.
  • Figure 1 is a perspective view, seen from below of a turnbuckle spigot assembly in accordance with the present invention, shown in exploded and cut-away view;
  • Figures 1A and IB are a part cross-sectional side views of the turnbuckle spigot assembly of Figure 1 shown at 90° to each other along its axis;
  • Figures 2A and 2B are part cross-sectional side views of the turnbuckle spigot assembly of Figure 1 shown attached between two main members of a two adjacent trusses;
  • Figures 3A and 3B are an edge view and a side view respectively, of a turning element of the turnbuckle spigot assembly of Figure 1;
  • Figure 3C is two side views, one at 90° axially to the other, of a threaded member of the turnbuckle spigot assembly of Figure 1;
  • Figure 3D is a cross-sectional side view of a first spigot of the turnbuckle spigot assembly of Figure 1;
  • Figure 3E is a cross-sectional side view of a second spigot of the turnbuckle spigot assembly of Figure 1;
  • Figure 3F is a side view and an end view of a pin of the turnbuckle spigot assembly of Figure 1; and, Figure 4 is a side view of two trusses coupled together by the turnbuckle spigot assembly of Figure 1.
  • a turnbuckle spigot assembly 10 comprising a turning element 20, a bolt 22, a first spigot 24, a second spigot 26 and two pins 28 and 30.
  • the turning element 20 is substantially cylindrical and has an axial hole 40 which is surrounded by two annular recesses 42, one on each side of the turning element 20.
  • the turning element 20 also has a keyway 44 disposed parallel to the axis of the hole 40 and extending through the recesses 44 and into the hole 40.
  • the turning element 20 further has an outer curved surface 45 which has a plurality of indents 46 formed in it at substantially equal distances around the curved surface 45. The indents 46 are intended to enable a C-spanner to be used to turn the turning element 20 circumferentially.
  • the bolt 22 comprises a head 50, a shank 52 and a keyway 54.
  • the shank 52 is threaded at least part-way along its length. Typically, the thread is relatively fine so as to avoid accidental loosening of the bolt 22 due to vibration.
  • the keyway 54 is disposed substantially parallel to the axis of the bolt 22. Typically, the keyway 54 extends along a substantial portion of the length of the shank 52 from its end towards the head 50.
  • the keyway 54 is designed to overlie the keyway 44 in the turning element 20 so as to receive a key 60 (see Figure 3B) to fix the turning element 20 to the bolt 22. Hence, rotation of the turning element 20 causes rotation of the bolt 22 by virtue of the key 60 engaged in the keyways 44 and 54.
  • the first spigot 24 comprises a cylindrical wall 70 which defines a cavity 71.
  • the cavity 71 has an annular shoulder 72 located towards one end 74.
  • the shoulder 72 and the wall 70 define a hole 76 which extends from the cavity 71 to the end 74.
  • the hole 76 is dimensioned to receive the shank 52 of the bolt 22 and the cavity 71 is dimensioned to receive the head 50 of the bolt 22.
  • the end 74 of the first spigot 24 is dimensioned to fit into the recess 42 in the side of the turning element 20 and is able to rotate with respect thereto.
  • the second spigot 26 is substantially the same as the first spigot 24 and like numerals denote like parts.
  • the second spigot 26 differs from the first spigot 24 in that its shoulder 72 and the end 74 define a hole 80 which is threaded for receiving the threaded shank 52 of the bolt 22.
  • the pins 28 and 30 each have a head 90, a shank 92 and a hole 94 located at the end of the shank 92 remote from the head 90.
  • the shank 92 is dimensioned to pass through the holes 78 in the spigots 24 and 26, with the head 90 bearing against the cylindrical wall 70 of the spigots 24 and 26 and the hole 94 located on the outer side of the cylindrical wall 70 for receiving a clip to secure the pin 28, 30 into the holes 78.
  • the turnbuckle spigot assembly 10 is made from metal materials although it could be made from plastics materials or the like or it could be made from a combination of materials.
  • the shank 52 of the bolt 22 is inserted into the cavity 71 of the first spigot and passed through the hole 76.
  • the shank 52 is then passed through the hole 40 in the turning element 20 and the keyways 44 and 54 are aligned.
  • key 60 is then inserted into the keyways 44 and 54 so that the bolt 22 will rotate together with the turning element 20.
  • the threaded shank 52 of the bolt 22 is then threaded into the threaded hole 80 in the second spigot 26 to complete the assembly of the turnbuckle spigot assembly 10.
  • the first spigot 24 is then inserted into a main member 100 of a truss 102 as shown in Figure 4.
  • the pin 28 is inserted through holes in the main member 100 and through the holes 78 in the cylindrical wall 70 and fixed in position with a clip through the hole 94 in the end of the pin 28 to secure the first spigot 24 to the main member 100.
  • Another truss 104 is brought into position so that its main member 106 is aligned with the second spigot 26.
  • the second spigot 26 is rotated so that the hole 78 generally aligns with corresponding holes in the main member 106.
  • the main member 106 is then pushed over the second spigot 26 and the turning element 20 rotated so that the holes 78 align with the holes in the main member 106.
  • a tapered end rod may also be used to assist in the alignment of the said holes.
  • the pin 30 is then inserted through the said holes and secured in position with a clip through the hole 94 in the end of the pin 30.
  • the turning element 20 is then rotated to draw the two main members 100 and 106 together so as to tighten the two trusses 102 and 104 securely and rigidly together to form a single truss span.
  • a C-spanner is then applied to the indents 46 of the turning element 20 to turn the turning element 20 to tighten it even further and to reduce the likelihood of inadvertent loosening due vibration and the like.
  • the turnbuckle spigot assembly 10 of the present invention has the effect of drawing adjacent trusses very closely together, i.e. spaced apart only by the width of the turing element 20. Also, since the turnbuckle spigot assembly 10 can be assembled and secured between the two main members 100 and 106 before tensioning it is possible to use it with difficult trusses such as rectangular trusses and the like. That is, the turnbuckle spigot assembly 10 has the advantage that it makes the alignment and securement of adjacent trusses much easier than with prior art systems for joining adjacent trusses.
  • an anti-slip device is inserted between the end 74 of the first spigot 24 and the turning element 20.
  • the anti-slip device is a spring washer.
  • the anti-slip device is an elongate pin located in the cylindrical wall 70 and spring biased towards the recess 42 of the turning element 20.
  • the recess 42 has an undulating groove in it so that the end of the pin rides up and down in the undulating groove as the turning element 20 is turned.
  • the turnbuckle spigot assemblies 10 can be used to connect collapsible box trusses of the type described in my co-pending patent application entitled Collapsible Box Truss which is considered to be brought into this specification by reference.
  • the spigots 24 and 26 could be other than cylindrical, such as, for example, irregular, square, triangular or rectangular of the like, although it is preferred that their cross-sectional shape conform generally with the internal shape of the main members of the truss.
  • the turning element 20 could be other than cylindrical, such as for example, square, triangular or rectangular or the like.
  • the bolt 22 could be threaded into a box, a beam, a wall or the like, instead of the second spigot 26, for terminating the assembly to other than another truss. That is, the second spigot 26 could be formed into a box or beam or wall or the like.
  • the turnbuckle spigot assembly 10 could be used to couple rigid hydraulic pipes together.
  • O-ring seals are used to seal the bolt 22 and the turning element 20 to the spigots 24 and 26.
  • the bolt 22 has a hole passing along its length to allow the flow of hydraulic fluid between the cavities 71 in the spigots 24 and 26.
