  • the apparatus 1 is used for connecting to first and second tubes 1.1 , 1.2, thereby allowing the tubes 1.1, 1.2 to be joined together.
  • the apparatus can be used in different configurations, for example to allow a tube to be connected to other objects, as will be described in more detail below.
  • the apparatus 1 includes first and second arm pairs, each having respective first and second arms 1.3a, 1.4a, 1.3b, 1.4b for insertion into respective ends of the tubes 1.1, 1.2.
  • the apparatus 1 also includes screws 1.5, 1.6, for engaging the arms 1.3a, 1.4a, 1.3b, 1.4b of each arm pair.
  • Each screw 1.5, 1.6 is mounted in a threaded aperture so that rotation of the screw 1.5, 1.6 urges the arms 1.3a, 1.4a, 1.3b, 1.4b apart thereby causing the arms 1.3a, 1.4a, 1.3b, 1.4b to engage an inner surface of the respective tube 1.1, 1.2.
  • this allows the arms 1.3a, 1.4a, 1.3b, 1.4b to positively clamp the tubes 1.1, 1.2 thereby securing the tubes 1.1 , 1.2 to the apparatus 1 , and in turn joining the tubes 1.1, 1.2. Accordingly, it will be appreciated that this provides an easy mechanism for allowing tubes to be connected to each other.
  • the apparatus includes two bodies 1.3, 1 ,4, each body defining respective first and second arms 1.3a, 1.3b, 1.4a, 1.4b of the arm pairs.
  • the bodies 1.3, 1.4 are substantially laminar and can be formed from any suitable material such as metal, plastic, composites, or the like, depending on a preferred application. It will be appreciated from that this allows the bodies 1.3, 1.4, to be easily manufactured, for example by punching out the bodies 1.3, 1.4 from a large sheet of material.
  • the bodies could be a single component of varying thickness and profile or an assembly of two or more components, depending on the preferred implementation.
  • the arms 1.3a, 1.4a, 1.3b, 1.4b are typically arranged to fit snugly within the tubes 1.1, 1.2, thereby avoiding the tubes 1.1, 1.2 moving relative to the apparatus under load. Additionally, the arms 1.3a, 1.4a, 1.3b, 1.4b may have a profiled surface shaped in a complimentary manner to that of the inner surface of the tube, thereby further enhancing engagement between the arms and the respective tubes 1.1 , 1.2.
  • each body 1.3, 1.4 has as a characteristic a slightly protruding ridged surface for all or part of the arm length, allowing the arms 1.3a, 1.3b, 1.4a, 1.4b to positively engage the rigid tube inner wall material as the arms 1.3a, 1.3b, 1.4a, 1.4b are spread apart to positively clamp the tube on the inside.
  • the arms 1.3a, 1.3b, 1.4a, 1.4b may also include engaging pads (not shown) for engaging the inner surface of the tube 1.1, 1.2.
  • the engaging pads can be made from a material having desired properties, such as resilience, or a high coefficient of friction.
  • the use of a resilient material allows the pad to deform, which can help ensure a high contact surface area between the pad and tube 1.1, 1.2.
  • the use of a high friction material can help reduce the chance of the tubes 1.1, 1.2 slipping off the arms 1.3a, 1.3b, 1.4a, 1.4b, for example if the screw has not been adequately tightened.
  • each arm 1.3a, 1.3b, 1.4a, 1.4b can be slotted such that when the screw 1.5, 1.6 is acting on each body to spread the arms 1.3a, 1.3b, 1.4a, 1.4b in order to clamp, the slot expands resulting in a positive clamping action perpendicular to the axis of the tube and the axis of the screw.
  • the threaded aperture can be an aperture 1.3c, 1.3d made directly in the arms 1.3a, 1.3b.
  • the arms include apertures 1.3c, 1.3d for receiving inserts 1.7, 1.8, each having a respective threaded aperture 1.7a provided therein.
  • the apertures 1.3c, 1.3d are both provided on the same body 1.3, although this is not essential as will be described in more detail below.
  • the apertures 1.3c, 1.3d and inserts 1.7, 1.8, may be coupled together using any suitable technique, as will be appreciated by persons skilled in the art.
  • the tubes 1.1, 1.2 typically include tube apertures 1.1a, 1.2a, which in use align with the apertures 1.3c, 1.3d provided in the arms 1.3a, 1.3b.
  • a tool such as an Allen key to be inserted through the tube apertures 1.1a, 1.2a, 1.3c, 1.3d and thereby engage a key or flat in or on the head of the screws 1.5, 1.6, which in turn allows the screw 1.5, 1.6 to be rotated using the tool.
  • This enables the arms 1.3a, 1.3b, 1.4a, 1.4b to be urged together or apart, depending on the direction of rotation of the screw 1.5, 1.6 thereby allowing the tubes 1.1, 1.2 to be selectively clamped.
  • the above described apparatus 1 connects two pieces of rigid hollow tubes 1.1 , 1.2 and includes a first body 1.3 with two arms 1.3a, 1.3b, of size such that each arm fits snugly into the corresponding tube 1.1, 1.2 to be connected, and with an aperture 1.3c, 1.3d in from each end of the body 1.3; a second body 1.4 with two arms 1.4a, 1.4b of size such that each arm fits snugly into the corresponding tube 1.1, 1.2 to be connected; and a screw 1.5, 1.6 matching a threaded aperture associated with the apertures 1.3c, 1.3d, the screw having a determined length and length of thread along a shaft of the screw such that it will allow the screw 1.5, 1.6 to part the arms 1.3a, 1.4a, 1.3b, 1.4b to a distance equal to or larger than a required distance to positively clamp the inside of the tubes 1.1 , 1.2 to be connected.
  • Each tube 1.1 is a first body 1.3 with two arms 1.3a, 1.3b, of size
  • the two bodies 1.3, 1.4 are oppositely positioned inside the corresponding tube 1.1 , 1.2 to be attached, such that the apertures 1.3c, 1.3d in the first body 1.3 align with the tube apertures I . la, 1.2a in the tubes 1.1, 1.2.
  • the corresponding screws 1.5, 1.6 can be inserted through the tube apertures 1.1 , 1.2a and screwed into the apertures 1.3c, 1.3d of the first body 1.3 until the end of the screw pushes against the opposing second body 1.4 positioned inside the tubes 1.1, 1.2.
  • the screws 1.5, 1.6 will force the two opposing bodies 1.3, 1.4 apart inside the tubes 1.1, 1.2, until the bodies have positively clamped the attached tube on the inside of the tube.
  • a shouldered or tapered aperture insert 1.7, 1.8 can be provided for each aperture 1.3c, 1.3d in the first body 1.3.
  • a shank diameter and length of shank 1.7b are such that each insert can be fitted into each aperture 1.3c, 1.3d in the first body 1.3 to a depth limited by a shoulder 1.7c on the insert 1.7, 1.8, or a taper on an insert shank 1.7b, such that the insert shank 1.7b will not protrude past a face of the first body 1.3 opposite the side of insertion of the insert into the body 1.3.
  • the inserts 1.7, 1.8 can be held in position using any suitable technique, such as a weld, solder, glue, interference fit or other mechanical means. Additionally, the inserts may include ridges that engage to prevent rotation of the inserts 1.7, 1.8, within the apertures 1.3c, 1.3d.
  • inserts increase the localised thickness of the body in the area of each aperture 1.3c, 1.3d in the first body 1.3, thereby maximising engagement between the screw and the threaded aperture, and hence the force that can be applied to the arms using the screw.
  • the profile of the bodies 1.3, 1.4 can also vary depending on the preferred implementation.
  • the bodies 1.3, 1.4 could be such that two or more tubes 1.1, 1.2 are joined together at different angles in relation to one another, in the same plane or different planes, or a specialised end bracket or part, forming part of or attaches to, one or both body arms, where such end bracket or part attaches to a single tube.
  • each attachment point has two arms, insertable into the end of the hollow rigid tube to be attached.
  • One of the arms has a threaded aperture or a threaded aperture insert through which a screw is driven to force the arms apart inside the tube to be connected. This allows the arms to be inserted from the end of the tube thereby positively clamping the hollow tube internally.
  • first and second bodies 1.3, 1.4 are replaced with alternative first and second bodies 2.3, 2.4, each having a single aperture 2.3c, 2.4c, provided in one of the arms 2.3a, 2.3b, 2.4a, 2.4b. It will be appreciated that this allows the first and second bodies to have an identical form, which can reduce the complexity of manufacture and hence cost.

  • this allows the arms 3.3a, 3.4a to positively clamp the tube 3.1 thereby securing the tube 3.1 to the apparatus 3.
  • the threaded aperture can be an aperture on one of the arms 3.3a, 3.4a, or can be provided using an insert similar to the inserts 1.7, 1.8 described above. It will be appreciated that this therefore operates in a manner similar to the tube connecting apparatus described above.
