Abstract: A portable apparatus for retaining a bicycle in the manner of a conventional bicycle repair stand, and which can be used in conjunction with a conventional sports rack attached to the roof of a car or van. The apparatus can be attached to the conventional bicycle sports rack which is attached to the roof of a car and therefore utilizes the car and the sports rack as the supporting body framework to hold and support a bicycle in any desired orientation. The apparatus comprises an elongated member whose exterior cross-sectional dimensions are slightly smaller than the interior cross-sectional dimensions of the elongated base of a conventional sports rack attached to the roof of a vehicle, and is fitted into the interior section of the elongated base of the sports rack and retained therein by a press fit. Additional portions attached to the elongated section support a clamping mechanism which can retain a portion of a bicycle such as the horizontal tube of the frame.

Abstract: A car top bicycle carrier in which a bicycle is supported in an upright, fully assembled position. There is a generally V-shaped trough into which the bicycle tires are placed and one or more straps for retaining the tires in the trough. A U-shaped stanchion is provided with a clamping mechanism for clamping the upper part of one of the bicycle wheels so as to retain the bicycle in an upright position and against movement longitudinally of the trough. The clamping mechanism can be adapted to bicycles with relatively large wheels and to bicycles with relatively small wheels.
