Definitions

  • This invention relates to elongate objects which move in a fluid medium. More particularly, but not exclusively, the invention relates to elongate objects including air flow guiding means which reduce the noise generated by the elongate objects in an air flow.
  • the invention relates to vehicle roof mounted luggage carriers in general and in particular the horizontal cross bars on vehicle roof mounted luggage carriers but it must be appreciated that the invention is applicable to a wide range of articles.
  • a common form of roof rack consists of a horizontal bar, movably attached to which are two supporting and mounting brackets, one located at, or near, each end of the bar, which provide facility for attachment of the assembly to a vehicle.
  • This configuration can be used singly, or in multiple, depending on the load carrying requirements of the user, and is frequently capable of having affixed to it various additional load carrying attachments such as canoe and bike racks, lockable bins and ski racks.
  • This type of rack is quite popular due to its versatility, however, it is particularly prone to producing a loud and annoying howling or humming noise due to the phenomena previously described.
  • the primary object of the invention is to provide an elongate object, in particular a vehicle roof rack cross bar, which, in use, generates low levels of audible noise over a wide range of operating speeds.
  • an elongate vehicle appendage including air flow guiding means defining air flow diverting channels along a leading edge which, in use, direct the flow of air around the vehicle appendage in such a manner as to reduce audible noise associated with vortex shedding.
  • the fluid flow guiding means may be integrally formed with the vehicle appendage or be in the form of one or more discrete elements attachable to the vehicle appendage.
  • the channels may be in the form of groves or conduits which direct portions of the fluid flow in a desired manner.
  • the flow diverting channels are angled groves provided at intervals along the vehicle appendage.
  • the groves along the length of the vehicle appendage are preferably parallel to each other.
  • the vehicle appendage may be of rectangular, tear drop or foil cross- section.
  • Figure 1 shows a roof rack according to a first embodiment of the invention in place on a vehicle roof
  • Figure 2 shows a front view of a portion of a cross bar of the roof rack shown in figure 1
  • Figure 3 shows a perspective view of a portion of a cross bar of a roof rack shown in figure 1 with lines indicating experimentally observed directions of fluid flow.
  • Figures 4a & 4b show cross sectional views of a cross bar of a roof rack shown in figure 1 with lines indicating experimentally observed directions of fluid flow with the cross bar in two different aspects with respect to direction of fluid movement.
  • Figures 5a & 5b show perspective views of a tear drop or foil type cross bar incorporating the air flow diverting channels of the invention.

  • Figure 1 2 shows a perspective view of a roof rack cross bar according to a further embodiment having a continuous air flow guiding means provided along a leading edge thereof.
  • Figure 1 3 shows a perspective view of a pantograph of an electric train.
  • the preferred cross bar 1 consists of a rectangular section of a length suitable for the vehicle on which its use is intended.
  • the cross bar 1 is preferably of approximate dimensions 30mm wide and 20mm deep and has rounded corners between adjacent faces.
  • this side being a narrow side, there are formed a plurality of air flow diverting channels 2 spaced at intervals across the cross bar 1 , such intervals preferably ensuring that the point where an air flow diverting channel 2 exits the upper edge of the cross bar 1 is horizontally displaced on the plane 30 (see figure 3) of the cross bar from any flow diverting channel 2 exiting the lower edge of the cross bar 1 such that an air flow 10 exiting an upper opening of an air flow diverting channel 2 and passing toward the rear of the cross bar 1 does not arrive at the leeward edge of the cross bar 1 above an air flow 9 having exited a lower opening of a air flow diverting channel 2.
  • Each air flow diverting channel 2 is formed at an angle 6 across the narrow face of the cross bar 1 , such angle being sufficient to ensure the upper opening of the flow diverting channel 2 is displaced, in a direction along the cross bar 1 , by a distance preferably not less than approximately 1 .5 times the width of the air flow diverting channel 2.
  • the dimension of each air flow diverting channel 2 is preferably between 2mm and 20mm wide and more preferably approximately 10mm wide and between 2mm and 10mm deep and more preferably approximately 6mm deep. In the preferred embodiment all edges and corners of the flow diverting channels 2 are rounded and smoothed.
  • the distance between air diverting channels is preferably between 20 to 80mm, and more preferably about 50mm.
  • the air flow diverting channels 2 are preferably arranged such that all air flow diverting channels 2 on one side of the lengthways centre of the cross bar 1 are arranged parallel to each other and all air flow diverting channels 2 on the remaining side of the lengthways centre of the cross bar 1 are arranged parallel to each other and more preferably all air flow diverting channels 2 across the full length of the cross bar 1 are arranged parallel to each other.
  • the cross bar 1 When mounted above a vehicle roof 4, by way of a set of roof rack bar supports 5, the cross bar 1 is aligned such that the side of the cross bar 1 containing the air flow diverting channels 2 is facing the vehicles direction of travel 3.
  • air striking the cross bar 1 is split, by passage of the cross bar 1 through it, into air 7 passing under the cross bar 1 and air 8 passing over the cross bar 1 (see figure 3).
  • the airflow diverting channels 2 tend to concentrate the air flows 9, 1 0 that come under their influence such that the air flows 9, 10 exit the air flow diverting channels 2 in a jet like manner and briefly separate from the cross bar 1 before rejoining near the leeward edge. From the experimentally observed flow patterns it can be seen that the flows 9, 10, influenced by the air flow diverting channels 2, while displaced from each other across the plane 30 of the cross bar and thus being prevented from intersecting, actually tend to pass each other in a plane 31 normal to the cross bar. This effect, combining altered airflows 9, 10 with horizontal displacement of said flows serves to suppress noise generation by reducing the occurrence of vortex shedding.
  • the air flow striking a roof rack cross bar 1 is often influenced by the near presence of the vehicle wind screen such that the air coming up the wind screen, frequently referred to as screen wash, causes the air striking the front of such a cross bar 1 to strike said cross bar 1 from an angle 1 5 below the horizontal (see figure 4).
  • Noise levels in this table are expressed in dB.
  • the base noise level of the wind tunnel has been subtracted and the overall noise levels of the plain and foil cross bars are given relative to the preferred embodiment.
  • the preferred embodiment has met its primary objective of producing a rectangular cross bar at least as quiet as a tear drop or foil shaped bar. It has also demonstrated itself to be considerably less susceptible to the effects of screen wash than either the plain bar or the foil shaped bar tested.
  • the air flow diverting channels When applied to a tear drop or foil shape cross bar 1 6 (see figure 5) the air flow diverting channels may be formed 17 so as to wrap around the leading edge of the cross bar 1 6, in a manner so as to preserve the reduced wind resistance characteristics of such a profile cross bar, or they may be formed 30 to pass through the cross bar without attempt to internally match the cross bars 1 6 profile. This would produce a similar effect to the rectangular section cross bar 1 and thus extend the optimised operating speed range for the tear drop or foil shape cross bar 16 by preventing the return of the vortex shedding phenomena that would otherwise be exhibited at higher speeds by a tear drop or foil shape bar.
  • FIG 6 a rectangular profile cross bar 18 where the angled air deflecting slots 2 of the preferred embodiment have been replaced by notches 19, 20 formed in the upper and lower windward corners of the cross bar 18. Such notches are considered to be provided along leading edges of the cross bar 18.
  • Each upper notch 19 is adjacently paired with lower notch 20 such that the air flows passing through an upper notch 19 do not intersect with the air flows passing through a lower notch 20.
  • This embodiment has been tested in practical use, and has been found to work well.
  • FIG 7 is shown an embodiment combining a rectangular profile cross bar 21 , a flow amplifying channel 22 and air flow diverting channels 23.
  • the flow amplifying channel 22 serves to increase the air flows passing through the air flow diverting channels 23 and over or under the cross bar 21 by diverting air striking across the full width of the cross bar 21 along the flow amplifying channel 22 to where these flows can find vent through the air flow diverting channels 23, thus adding to the air flows already passing through the air flow diverting channels 23.
  • This embodiment has been tested in practical use and in a wind tunnel and has been found to work well to prevent vortex shedding but not to be quite as quiet, with respect to general wind noise, as the preferred embodiment.
  • FIG 8 is shown an alternative embodiment where the air flow diverting channels are in the form of conduits 26 & 27 passing from the windward side, being the side facing the direction of travel 3, of a rectangular section cross bar 24 toward the top 29 and bottom 28 leeward corners of the cross bar 24.
  • the upper conduits 27, passing from the windward side of the cross bar 24 toward the upper leeward corner 29 of the cross bar 24 are angled toward one side of the vehicle while the lower conduits 26, passing from the windward side of the cross bar 24 toward the lower leeward corner 28 of the cross bar 24 are angled toward the opposite side of the vehicle.
  • the conduits are so spaced as to ensure the upper conduits 27 exit in a position horizontally displaced from the exit point of the lower conduits 26.
  • a flow amplifying channel 25 passing along the length of the cross bar 24.
  • the purpose of the flow amplifying channel 25 is to trap air striking the full width of the front of the cross bar 24 within the confines of the flow amplifying channel 25 and thus create an area of higher pressure that is forced to find vent through the conduits 26, 27 thus maximising flow passing through these conduits.
  • the above embodiments are used in exactly the same manner as any other similarly dimensioned rectangular cross bar would be used and can have affixed to it all of the many specialised load carrying attachments designed to work with the 30mm x 20mm rectangular profile and, provided it is mounted with the air flow diverting channels facing in the direction of travel the preferred embodiment will produce substantially less noise than a similarly dimensioned cross bar without air flow diverting channels and no more noise than a tear drop or foil shaped cross bar.
  • the fluid flow guiding means is in the form of one or more discrete element which is attachable to the cross bar.
  • cross bar 35 is provided with holes 33 along its leading edge.
  • a plurality of fluid flow guiding means 36 are affixed via projections 32 which engage in holes 33 to secure the fluid flow guiding means to the leading edge of cross bar 35.
  • the fluid flow guiding means are so spaced as to define fluid flow channels 34 therebetween.
  • cross bar 35 may be secured to a roof rack. Once fittings have been secured to the roof rack fluid flow guiding means 36 may be positioned in the available locations. This construction enables a cross bar 35 of standard dimensions to be produced with the only modification being the drilling of holes 33 along the leading edge.
  • Fluid flow guiding means 36 may be formed of plastics or the like by injection moulding or other suitable processes.
  • cross bar 40 has a T slot 41 formed along the leading edge of cross bar 40.
  • Fluid flow guiding means 42 are provided with T-shaped formations 43 which slideably engage within T slot 41 .
  • At least one side of the roof rack must be detached from cross bar 40 to allow fluid flow guiding means 42 to be fitted (unless they are constructed of sufficiently resilient material that the T shaped portions 43 may be push fitted into T slot 41 ). Assembly may be slightly less convenient than for the arrangement shown in figure 9 but the fluid flow guiding means 42 will be securely retained in this embodiment.
  • fluid flow guiding means 51 are provided at intervals along cross bar 50.
  • cross bar 50 is a steel cross bar of standard constructions requiring no modification.
  • Fluid flow guiding elements 51 include a magnetised material enabling fluid flow guiding elements 51 to be magnetically secured to cross bar 50.
  • fluid flow guiding means 51 can be placed at any desired spacing to form channels 52.
  • Fluid flow guiding means 51 may be cut to desired lengths to fit around roof rack fittings.
  • Fluid flow guiding means 51 may alternatively be provided with adhesive on the undersides thereof to enable them to be secured to a cross bar .
  • Elements 51 may be provided on a support strip at a desired spacing so that an entire assembly can be secured to a cross bar in one action.
  • a suitable backing strip may be provided over the adhesive applied to elements 51 for ease of handling prior to attachment.
  • fluid flow guiding means 61 is of continuous construction and may be fitted over cross bar 60 of standard dimensions. Channels 62 are formed in fluid flow guiding means 61 . Fluid flow guiding means 61 may be formed of plastics or other suitable material.
  • pantograph 70 of an electric train is shown.
  • the techniques of the invention, as applicable to this application, may be applied to cross bars 71 to minimise audible noise.
