Definitions

  • Apparatus for joining two members together is disclosed.
  • the apparatus finds application with furniture such as modular furniture, but is ' not limited to this application.
  • Some furniture especially modular furniture, is supplied unassembled for assembly on site.
  • some members must be sized and modified on site to suit the location in which the furniture is employed. This can especially be the case in office fitouts, where the specifications may change when furniture assembly commences.
  • an apparatus for joining two members together comprising:
  • an at least partly spherical element adapted for mounting to one of the members; and a socket mechanism adapted for mounting to the other member and comprising a plurality of components which, when the socket mechanism is mounted to the other member, are combined to define a socket for receiving and supporting the element for movement therein.
  • Such a joining apparatus allows for joining to take place despite some movement between members and can find application, for example, where dimensions of the member(s) and/or alignment between the members need to change. This could occur on site where, for example, the members define components in modular furniture and angles or dimensions need to be changed.
  • the other member can be a tube, and a portion of the socket mechanism can be mounted to an open end of the tube.
  • the portion of the socket mechanism may be located within and/or surround the tube.
  • the portion may comprise an extension from each component of the socket mechanism, which extensions are received inside the tube open end in a manner such that, when received, the tube holds the plurality of components together to define the socket.
  • the apparatus may further comprise fixing means for securing the tube to the socket mechanism.
  • fixing means for securing the tube to the socket mechanism.
  • an interior surface of the tube end and an exterior surface of the portion may be respectively threaded for screw mating.

  • Spherical element 10 comprises a ball portion 12 that is substantially spherically shaped, and a mounting extension 14 by which the spherical element 10 may be mounted to a member, as discussed below.
  • the spherical element 10 has a hollow interior 16 which, as is best seen in Figure 3, extends from one side of the spherical element 10 to the other.
  • the hollow interior 16 has a first opening 18 in the ball portion 12, and a second opening 20 in the mounting extension 14. Both first opening 18 and second opening 20 are substantially circular in shape so that the hollow interior 16 is defined by two cylindrical bores extending through the spherical element 10. As can be seen from Figure 3, a step 22 is defined in the hollow interior 16 at the intersection of the first bore defined by first opening 18, and the second bore defined by the second opening 20. The step provides a mounting surface for a screw or bolt head as described hereafter.
  • the spherical element 10 may be mounted to a first member in the form of first tube 24, as shown in Figure 7, by an attachment device such as a screw or bolt, which is anchored between the inside of the wall of the first tube 24 and the step 22.
  • the attachment device may comprise a nut and bolt assembly, where a hole has been pre-drilled into the wall of the first tube 24.
  • the stem of the bolt (not shown) passes through the hole whilst the head of the bolt, with a washer if necessary, remains inside the first tube 24 and abuts the inside wall of the first tube 24.
  • the spherical element 10 may be mounted onto the first tube 24 bypassing the stem of the bolt through the second opening 20 so that it enters the hollow interior 16.
  • a nut (and a washer if necessary) may then be screwed onto the threaded stem of the bolt via the first opening 18, until the washer or nut abuts the step 22, thereby securely affixing the spherical element 10 to the first tube 24.
  • the end of the mounting extension 14 which abuts the first tube 24 may, as desired, be shaped to facilitate a flush contact with the outer wall of the first tube 24, which is typically circularly shaped.
  • Socket half element 26 has a socket portion 28 and a socket mounting extension 30.
  • the socket portion 28 has a wall 32 which is substantially hemi-spherically shaped and which defines a chamber 34 which is shaped such that half of the ball portion 12 may be matingly received therein.
  • the socket mounting extension 30 has a mounting wall 36 which is semi- circularly shaped in cross-section and has an outer radius approximately the same as the inner radius (i.e. of the bore) of second tube 38, shown in Figure 7.
  • the socket mounting extension 30 also has an inner recess 40 to reduce its weight.
  • Recess 40 can be semi-circularly shaped in cross-section to be adapted to receive a projection therein if so desired (see, for example, the description of Figure 8 below).
  • a step 42 is defined which provides an edge over which the second tube 38 cannot pass when mounted to two abutting and mirror-facing socket half elements 26, 26 when in the configuration described below.
  • the socket portions 28, 28 of two similar socket half elements 26, 26 are arranged about the ball portion 12 of the spherical element 10 so that it is received within the chambers 34, 34.
  • the ball portion 12 and chambers 34, 34 are shaped such that when the elements are positioned about it in this configuration, relative movement of the spherical element 10 with respect to the socket half elements 26, 26 is possible, thereby allowing relative movement of first tube 24 and second tube 38 as shown by the arrows in Figure 7.
  • the socket half elements 26, 26 can temporarily be held together by hand to define a socket element 44, and then the second tube 38 can be slid over the socket mounting extensions 30, 30 until the end of the second tube 38 abuts the steps 42, 42.
  • the socket half element 26, 26 may first be joined permanently, for example within an adhesive, screw etc.
  • the mounting walls 36, 36 closely face the inner wall of the second tube 38, which holds the two socket half elements 26, 26 together such that the ball portion 12 is securely encased within the chambers 34, 34 of the socket element 44.
  • the mounting wall 36 may have a fixing means for securing the second tube 38 to the socket element 44.
  • the interior surface of the end of the second tube 38 may be provided with a screw thread for screw mating with a screw thread provided on the mounting walls 36, 36.
  • the fixing means may alternatively comprise grub screws extending through tube 38 and insertible into respective walls 36, 36.
  • the second tube 38 maybe restricted from movement away from the steps 42, 42 by a restraining means at the other end of second tube 38.
  • the other end of second tube 38 may be mounted to another member by a similar joining apparatus to that described above, thereby restricting movement of the second tube 38 such that second tube 38 remains engaged with steps 42, 42, thereby holding the two socket half elements 26, 26 together.
  • crimping of the second tube 38 or applying an adhesive to the mounting walls 36, 36 prior to mounting the- second pipe 38 over the socket mounting extensions 30, 30.
