Self-tensioning hold down apparatus for a bicycle support rack

An apparatus for securing an object on a support rack, the apparatus comprising:

• a shaft, the shaft having a length with a proximal end and a distal end at opposite ends of the length of the shaft;
• the proximal end of the shaft being operatively connected to the support rack;
• a catch on the distal end of the shaft, the catch being configured for engaging against an object on the support rack and holding the object on the support rack;
• and
• a biasing device on the shaft, the biasing device being configured for biasing the catch toward the proximal end of the shaft and gripping the object between the catch and the support rack.

An apparatus for securing a bicycle on a bicycle support rack, the apparatus comprising:

• a shaft;
• a connection on the shaft, the connection operatively connecting the shaft to a bicycle support rack;
• a catch of the shaft, the catch being configured for engaging against a bicycle on the bicycle support rack;
• a pair of cradles on the support rack, the pair of cradles being configured to engage underneath a wheel of the bicycle on the bicycle support rack;
• and
• a biasing device operatively connected between the pair of cradles, the biasing device being operative to bias the pair of cradles together and exert a biasing force against the wheel of the bicycle on the support rack biasing the bicycle upward toward the catch and thereby gripping the bicycle between the catch and the support rack.
