Definitions

  • the present invention relates to an improved roof bar and connection system for connecting accessories to the roof bar.
  • Roof bars are known. Roof bars are generally elongate and extend across a vehicle. The roof bars are attached to the vehicle at screw or bolt fixings or via rails attached to the vehicle.
  • One known roof bar uses a T-track in the top surface of the roof bar for receiving the head of a bolt. Accessories are clamped to the roof bar using the bolt and T-track.
  • the T- track is generally filled with a weatherproof strip.
  • a roof bar having a generally tear-drop shaped cross-section, wherein a rear side of the bar is cut-off short of tapering to a point and such that the width of the bar is less at a mid-point of the cross section than at spaced positions on either side. Consequently, the roof bar has a depression on the rear facing surface.
  • the depression can be used to improve the attachment of accessories.
  • the roof bar has a generally constant cross-section.
  • the roof bar is extruded.
  • end caps are provided as is known in the art.
  • accessories including feet for attaching the roof bar to the vehicle, are connected to the roof bar.
  • the accessories are assembled using a saddle arranged to substantially envelope the outer periphery of the roof bar.
  • a tension means is provided to apply a compressive force across two portions of the saddle so as to clamp the saddle to the roof bar.
  • the saddle includes a protrusion that is received by the depression in the rear of the roof bar. Engagement of the protrusion and depression resist movement, for instance, rotation of the accessories about the bar, by keying together.
  • the tension means applies a compressive force between two portions of the saddle.
  • the tension means may be provided by the natural resilience of the saddle, however, preferably, the tension means is a component spanning the two portions.
  • the tension component is a pin or other elongate structure operating in combination with another part that can be secured to the tension component at different extents to apply the compressive force.
  • One of the parts could be integrally moulded to or with the saddle.
  • the tension component is shown as a nut and bolt. To improve the assembly of the tension component, the nut or bolt is captured integrally in the formation of the saddle.
  • the tension means may apply the compressive force transverse the front to back direction or parallel to it.
  • the tension means applies the compressive force transverse the front to back direction
  • the tension means is arranged across the front face of the roof bar.
  • the saddle wraps around the roof bar and the tension means acts to pull two portions of the saddle spaced in a top to bottom direction.
  • the tension means is arranged to extend in the front to back direction.
  • the saddle wraps around the roof bar and the tension means acts to pull two portions of the saddle spaced in a front to back direction.
  • the saddle forms an open mouth.
  • the open mouth accepts the roof bar.
  • the tension means is arranged to compress the open mouth around the roof bar.
  • the saddle has a degree of flexibility to allow the open mouth to compress.
  • the depression is brought into tighter contact with the roof bar improving the keying affect.
  • the saddle includes a hinge to open the mouth.
  • the hinge allows the mouth to be opened widely.
  • the open mouth can fit easily around the roof bar.
  • the hinge can be fitted from underneath.
  • the tension mea ns acts to close the hinge, typically from a closed position wherein the accessory fits the roof bar closely to a tensioned position, wherein the saddle is tightened around the roof bar.
  • the saddle is a single part with a main body of the accessory.
  • the saddle may be integral with the main body or may be a separate part fixed securely to the main body.
  • the saddle may be detachable from the main body.
  • the saddle has an open mouth that fits around the roof bar and connects to the main body.
  • the tension means is arranged within the main body and to close the open mouth. Consequently, the tension means acts to pull the saddle towards the main body.
  • the accessories may be any known accessory that requires attaching to the roof bar, for instance, load stops, fixing feet, or pipe tubes.
  • the accessory is a rear roller system.
  • Rear roller systems provide a transverse roller at the rear of a vehicle for use when loading and unloading elongate articles from the roof bar, for instance ladders.
  • the rear roller system includes first and second arms that extend rearwardly from the roof bar.
  • a roller is attached to the distal ends of the arms and extends between the arms in a width direction.
  • the arms are attached to the roof bar by brackets. It will be appreciated that the brackets may include the depression of the previous embodiments. However, for systems that do not employ the improved roof bar described herein, the bracket may be a known bracket.
  • each arm is formed from first and second arm pieces.
  • the first and second arm pieces are telescopically arranged.
  • the exemplary embodiments show first and second pieces that can be locked together to move the roller position relative to the roof bar.
  • this allows the roller to be used on vertical lift boot doors. That is, because the roller needs to overhang the rear of the vehicle, the telescopic nature of the arms, allows the roller to be stowed in a position not overhanging the rear of the vehicle allowing the boot to be opened, whist being able to be deployed when needed.
  • a supporting foot may be arranged on the arms as is known in the art.
  • the arms may be arranged to be positioned beneath, or above, the roof bar thereby allowing the arms to extend past the bracket.

Abstract

L'invention concerne une barre de toit (110) à section transversale globalement en forme de larme, le côté arrière de la barre étant amputé avant le rétrécissement jusqu'à la pointe, de sorte que la largeur de la barre est plus petite au niveau d'un point médian de la section transversale qu'en des positions espacées de chaque côté. Par conséquent, la barre de toit possède un creux (112) sur la surface orientée vers l'arrière. De façon avantageuse, le creux (112) peut être utilisé pour améliorer la fixation d'accessoires (120). Des accessoires, comprenant des pieds destinés à fixer la barre de toit (110) au véhicule, sont reliés à la barre de toit. Selon les modes de réalisation illustratifs, les accessoires (120) sont assemblés à l'aide d'un pont (130) agencé pour envelopper sensiblement la périphérie extérieure de la barre de toit. Un moyen tendeur (124) est prévu pour appliquer une force de compression sur deux parties du pont (130) de manière à serrer le pont sur la barre de toit (110). De façon avantageuse, le pont (130) comprend une saillie (132) qui est reçue par le creux (112) dans l'arrière de la barre de toit. L'entrée en prise de la saillie (132) et du creux (112) permet de résister au déplacement, par exemple à la rotation, des accessoires (120) autour de la barre, par un clavetage.
