Wheel holder, extension module and rear load carrier
The present invention relates to a wheel holder, which is designed such that it can be pushed on an end section of a profile rail ( 13 ) of a rear load carrier ( 1 ). Also the invention relates to an extension module ( 34 ) for carrying a load having attachment means for releasable attachment to a rear load carrier ( 1 ) comprising at least one profile rail ( 13 ), wherein the extension module ( 34 ) comprises one extension profile rail ( 35 ) and two wheel holders ( 12 ) which are preferably pushed on the free ends of the extension profile rail ( 35 ).
1 . Wheel holder for releasable attachment to a rear load carrier for mounting to a vehicle comprising at least one profile rail, wherein the wheel holder is designed such that it can be pushed on an end section of a profile rail of the rear load carrier, wherein
the wheel holder comprises a wheel holder body defining a lengthwise direction, which wheel holder body has a receiving opening open to a proximal end, wherein the receiving opening has a cross-section complementary to the cross-section of the profile rail of the rear load carrier so that the wheel holder body can be pushed on the profile rail and can surround the profile rail of the rear load carrier at least partially such that the wheel holder can be fixed in a form-fit manner perpendicularly to the lengthwise direction, wherein engagement projections are formed at both lateral sides of the receiving opening, which engagement projections engage inwards and upwards so that they can be brought into engagement into corresponding engagement grooves formed in the profile rail of the rear load carrier open downwardly.
2 . Extension module for carrying a load, having attachment means for releasable attachment to a rear load carrier for mounting to a vehicle, wherein the extension module comprises one extension profile rail and two wheel holders, which wheel holders are pushed on the free ends of the extension profile rail, wherein each wheel holder comprises a wheel holder body defining a lengthwise direction, which wheel holder body has a receiving opening open to a proximal end, wherein the receiving opening has a cross-section complementary to the cross-section of the extension profile rail of the extension module, so that the wheel holder body is pushed on the extension profile rail at least partially such that the wheel holder is fixed in a form-fit manner perpendicularly to the lengthwise direction of the extension profile rail, wherein engagement projections are formed at both lateral sides of the receiving opening, which engagement projections engage inwards and upwards so that they are brought into engagement into corresponding engagement grooves formed in the extension profile rail open downwardly.
3 . Rear load carrier for mounting to a vehicle, with a base body, which defines a longitudinal direction between its front side and its rear side and a transverse direction, a connecting device for attachment to a vehicle-side trailer coupling provided at the front side of the base body, and fixing means, which comprise at least two profile rails which are held on the base body and extend in the transverse direction, wherein at least one end of at least one profile rail, a wheel holder is pushed on, wherein the wheel holder comprises a wheel holder body defining a lengthwise direction, which wheel holder body has a receiving opening open to a proximal end, wherein the receiving opening has a cross-section complementary to the cross-section of the profile rail of the rear load carrier so that the wheel holder body is pushed on the profile rail and surrounds the profile rail of the rear load carrier at least partially such that the wheel holder is fixed in a form-fit manner perpendicularly to the lengthwise direction, wherein engagement projections are formed at both lateral sides of the receiving opening, which engagement projections engage inwards and upwards so that they are in engagement into corresponding engagement grooves formed in the profile rail of the rear load carrier open downwardly.
