- the present invention may be used with a range of vehicle ranging from vans, cars, motor homes or any number of a range of road based vehicles. Potentially, the invention could also be used with water vessels or rail carriages in other embodiments If required.
- the present invention incorporates a support frame which defines a platform on which cargo or loads may be placed to be supported.
- This support frame is connected to the vehicle, usually through a permanent connection system associated with the roof top area of the vehicle.
- a support frame may be formed by an array of slats aligned both transversely and longitudinally to form the body of the platform. This array of slats can also be surrounded and enclosed by a perimeter housing. The use of a slat type structure in the construction of the support frame substantially reduces the overall weight of the resulting structure and can minimise manufacturing costs.
- the present invention incorporates a plurality of modular rail elements. These rail elements can be arranged in various configurations, shapes or forms on the platform to provide one or more guard raiis. Each of these rail elements Is provided with a modular form to allow the component to be mass produced, thereby reducing manufacturing costs.
- the present invention is arranged and configured so that these modular rail elements can be removably engaged with the support frame or base platform - being either removably connected directly to the base platform or indirectly to the platform through a further element or component.
- a modular rail element may be formed by a substantially straight length of material with an upper rounded surface and a flat under side surface.
- a substantially straight length of material with an upper rounded surface and a flat under side surface.
- the rail elements may form at least one guard rail which defines or provides a barrier to loads moving during transportation when the vehicle is in transit.
- guard rails may be erected along the perimeter of the platform to maximise the carrying area of the support structure or alternatively may define a localised perimeter In a restricted region or area of the platform.
- a single guard rail may be provided which extends around the entirety of the platform. In another embodiment, a single guard rail may be provided which extends only around a portion of the platform, thereby enclosing an area of the platform.
- a single guard rail may be provided to divide up the surface area of the platform or potentially to prevent loads from moving over one edge only of the platform.
- a pair of guard rails may be provided on opposite sides of the platform, leaving two open unguarded ends to the platform for relatively large or long loads to extend over the edge of the platform.
- the modular nature of these rail elements, and the removable connection system provided allows for a high degree of flexibility in terms of the shapes, forms and arrangements of guard rails that can be deployed on the platform of the present invention.
- the rail elements may be formed or arranged so as to connect directly to the upper surface of a support frame or platform.
- a rail element may be formed by a relatively large or tall component, which has a height equal to the distance that the resulting guard rail extends above the platform.
- a rail element may be indirectly engaged with the support frame or platform through the provision of a modular base element
- a base element may provide an intervening component between the platform and rail element to elevate the rail element above the support frame platform.
- Such base elements may be arranged so as to removably connect or engage with the platform and also to removably engage or connect with one or more rail elements.
- the removable connection arrangement between the under surface of a rail element and a base may be provided through a channel, which is defined in the under side of a rail element with a restricted entry throat provided for this channel.
- a complimentary projection may be formed in the upper surface of a base element with a projecting head and narrow neck being provided in this projection. The head of this projection can be threaded through and into the channel defined in the rail and then be secured by the restricted throat of the channel.
- a removable connection arrangement may be provided between a base element and the support frame platform through a channel or trough formed in a section of one of the transverse or longitudinal slats of the platform.
- An entry aperture or opening with an increased span to that of the channel may be provided at one or more points along the length of a slat to allow for the entry of a locking lug, which is defined on the under side of a base element.
- This arrangement of the platform and base elements allows the locking tugs of the base elements to be introduced into one of a number of channels formed in the slats of the platform and to slide down to the appropriate position on the platform, where the base element is to be deployed.
- a number of such channels may be provided over the surface area of the platform to provide flexibility in the arrangements of guard rails on the platform.
- the load supporting structure provided may also include further components in addition to the modular rail elements, the support frame platform and the modular base elements discussed above.
- the load supporting structure may also incorporate or Include a number of modular end caps, which extend from an open end or face of a rail element down towards and into contact directly with the support frame platform, These end cap elements may close off the end of a rail element and provide the resulting structure with an aerodynamic form or shape and an aesthetically pleasing appearance.
- the load supporting structure may also incorporate corner sections that are arranged to indirectly connect two or more rail elements at an angle to one another.
- a corner element may be provided to connect two adjacent rail elements together substantially at a right angle to one another.
- Such corner elements can preferably be formed with similar profiles and dimensions to the rail elements, thereby improving the aerodynamic performance of the resulting structure and also its aesthetic qualities.
- the platform may also be arranged to removably connect other forms of accessories, which do not provide portions of a guard rail.
- the connection system employed to engage components of the guard rail with the platform may be used to engage or connect accessories, such as a bicycle carrier, canoe or kayak carriers, conduit retention tubes or any number of different customised elements directly to the upper surface of the support frame platform.
