Abstract
Bicycle carrier apparatus includes an H-shaped support frame bearing a pair of opposed threaded clamping members for rigidly gripping the bicycle pedal crank arm mounting bolts on opposite ends of the central crank arm shaft. A further support for the front wheel is provided in which the front wheel tire is frictionally engaged in a secure clamping device. A pair of individual bicycle carriers are affixed to a longitudinal support member which attaches to the receiver portion of a standard vehicle-mounted trailer hitch. An additional pair of bicycle carriers in a similar configuration may be connected to the first carrier apparatus by means of a simple connector assembly. A cartop rack is also disclosed as well as a variant which also mounts to a trailer hitch receiver.
Claims19
A bicycle carrier apparatus for supporting a bicycle by engaging the bicycle crank arms during transportation by a motor vehicle comprising:
- an elongate support member for coupling to a motor vehicle for support thereby;
- at least one individual bicycle carrier connected to the support member to support a bicycle aligned generally orthogonally to the support member, the carrier including:
- a support frame having a pair of clamping member support elements positioned to extend on opposite sides of a bicycle mounted therein;
- and
- a pair of axially opposed threaded clamping members aligned along an axis which is coaxial with the crank arm support shaft of a bicycle mounted in the support frame and threadably engaged in respective ones of said support elements, said clamping members having inner ends which are configured to engage the heads of the bicycle crank arm mounting bolts from opposite sides of the bicycle.
