  • Generic rolled 'strut type' channel shaped profiles are well known and used extensively throughout the construction industry, particularly but not exclusively within the UK, Europe, and Middle East. Such channel shape profiles are used, for example, to provide support for secondary light gauge frameworks and structures for the installation of services, pipe-work and Heating and Ventilation and Air- Condition (HVAC) systems.
  • HVAC Heating and Ventilation and Air- Condition
  • Such cables and the like may include locking clips and/or loop arrangements which allow the cable to be fitted around the channel shaped profile, extend downwards from the profile and be secured around or through a part of the secondary framework to be support thereby.
  • a first aspect of the present invention provides a fastening device for engagement with a channel portion having a base member, and first and second side members extending from respective edge regions of the base member to form a substantially U-shaped cross section, and defining respective first and second opposing inner surfaces, which are spaced apart by a first amount, the channel portion further having first and second retaining members which extend from free edge regions of the first and second side members respectively towards the other of the side members thereby defining an entry region having a width less than the first amount, the fastening device comprising a body having a width less than a width of an entry region of such a channel portion, and having opposing engagement surfaces spaced apart by an amount substantially equal to the first amount of such a channel portion, thereby enabling frictional engagement of the engagement surfaces with opposing inner surfaces of such a channel portion and substantially preventing linear movement of the fastening device within such a channel portion.
  • the fastening device may be entered into the channel portion by orienting the fastening device body such that the width of the fastening device is passed through the entry region. Once passed through the entry region and into the channel, the fastening device may then be rotated to bring the opposing engagement surfaces into frictional engagement with the opposing surfaces of the first and second side members.
  • the fastening means thus oriented, will be securely held in place within the channel by the retaining members and located in position by means of the frictional fit between the opposing engagement surfaces of the fastening device and respective opposing surfaces of the first and second side members.
  • each opposing engagement surface comprises a substantially planar portion and a substantially curved portion.
  • Each substantially planar portion may frictionally engage an opposing surface of one of the side members of the channel, whilst each substantially curved portion facilitates the rotation of the fastening device, once passed through the entry region, into frictional engagement with opposing surfaces of the first and second side members.
  • the substantially curved portions of respective engagement surfaces are diagonally opposed to one another.
  • the diagonally opposed curved portions are preferably mirror images of one another. This assists in the smooth rotation of the body of the fastening device within the channel.
