Roof mounted bike carrier

1. A supporting structure for a roof mounted bike carrier having a wheel tray, the supporting structure comprising:

a first attachment part and a second attachment part being separable from said first attachment part; and

a bike supporting device having a coupling section coupled to said first attachment part and adapted to support a bike with a supporting section thereof,

wherein said first attachment part and said second attachment part are adapted to be invertedly couplable to provide respective reversed positions of said bike supporting device with respect to said second attachment part.

2. The supporting structure according to claim 1 , wherein said first attachment part comprises a cross bar attachment part fixedly mountable on a cross bar of a vehicle load carrier system.

3. The supporting structure according to claim 1 , wherein said second attachment part comprises a wheel tray attachment part fixedly mountable to an underside of a wheel tray of said bike carrier.

4. The supporting structure according to claim 1 , wherein said bike supporting device is rotatably coupled to said first attachment part, wherein in a mounted condition an axis of rotation of said bike supporting device is parallel to a cross bar of a load carrier system of a vehicle.

5. The supporting structure according to claim 4 , wherein said bike supporting device and said first attachment part form an integral assembly.

6. The supporting structure according to claim 1 , further comprising a quick release mechanism adapted to couple and decouple said first attachment part and said second attachment part.

7. The supporting structure according to claim 6 , wherein said quick release mechanism comprises a rotatable coupling element rotatable between a locking position in which said second attachment part is fixedly coupled to said first attachment part and an unlocking position in which said second attachment part is separable from said first attachment part.

8. The supporting structure according to claim 7 , wherein said rotatable coupling element is adapted to be moved one-quarter rotation from said locking position to said unlocking position.

9. The supporting structure according to claim 7 , wherein said rotatable coupling element is configured to be operated by hand or by a screw driver.

10. The supporting structure according to claim 1 , wherein said first attachment part and said second attachment part comprise attachment openings adapted to accommodate attachment means to fix said first and second attachment part to a cross bar of a load carrier system, wherein said attachment openings are arranged in said first and second attachment parts such that attachment openings of said second attachment part are aligned with attachment openings of said first attachment part when said attachment parts are coupled to each other, and wherein said attachment openings are arranged symmetrically on said attachment parts.

11. The supporting structure according to claim 10 , further adapted to support said attachment means, said attachment means comprising a tensioning member and an engaging member, wherein said engaging member is formed as a T-shaped element and adapted to engage a corresponding nut, and wherein said attachment openings in said first attachment part are formed such that said engaging member is passable therethrough.

12. The supporting structure according to claim 1 , wherein said first attachment part comprises a covered bottom portion adapted to contact a cross bar of a load carrier system, wherein said covered bottom portion comprises a substantially continuous surface adapted to prevent accumulation of dirt on said load carrier and adapted to reduce noise generation.

13. The supporting structure according to claim 1 , wherein said supporting section is adapted to hold a bike frame, a crank arm, or a wheel of a bike.

14. A roof mountable bike carrier, comprising:

a wheel tray; and

a supporting structure comprising:

a first attachment part and a second attachment part being separable from said first attachment part, and

a bike supporting device having a coupling section coupled to said first attachment part and adapted to support a bike with a supporting section thereof,

wherein said first attachment part and said second attachment part are configured to be invertedly couplable to provide respective reversed positions of said bike supporting device with respect to said second attachment part,

wherein said supporting structure is mounted to said wheel tray with said second attachment part being attached to an underside of said wheel tray.
