  • Adjustable stop for telescoping tubes
    Patent number: 6719257
    Abstract: An adjustable stop attached to the smaller of two nested telescoping tubes. The stop is in the form of a sleeve that is axially and rotationally adjustable on the smaller tube. The sleeve is smaller in diameter than the inner diameter of the larger tube, and it has a detent for a pin extending inward from a tube clamp on the larger tube. The detent receives and releases the pin in both axial directions. This provides a detent at a selected relative extension and rotation position of the tubes, yet it also allows the smaller tube to fully retract into the larger tube. The tube clamp is used to fix the tubes at the detent position. The tube clamp is used conventionally to set a desired detent position.
