Abstract
A vehicle rack having frame members and a clamping device for securing a ladder to the frame members. The clamping device comprises a first clamp rigidly connected to one frame member to receive one of the rungs of the ladder, and a second clamp for engaging another rung of the ladder. The second clamp is rigidly connected to a rotatable rod to which a handle as connected. A link is provided for interconnecting the rod and a spring, the arrangement of the link and the member being such that the second clamp is biased alternatively in the engaged and disengaged positions so that moving the handle in one direction will cause the second clamp to engage a rung of the ladder, the second clamp being urged in the engaged position by the spring. While moving the handle in the other direction will cause the second clamp to disengage, the spring then urging the second clamp in the disengaged position.
