LATCHING DEVICE FOR INSERTION INTO A TUBE FOR LATCHING MOVEMENT OF THE TUBE RELATIVE TO AN EXTERNAL ELEMENT

摘要

A latching device for insertion into a tube provides two large flatbuttons one on each side to lock the tube relative to an outer tube or to twoparallelplates. A tubular housing with open ends slides into the tube between the sidewallsof the tube with the ends of the housing substantially butting inside surfacesof theside walls. The buttons are mounted on respective slide members mounted in thehousing spring biased apart so that the buttons can be depressed. One or twosetscrews acting as stop members can be inserted after the housing is moved totherequired location in the tube to prevent depression of the buttons to aposition inwardof the inner surface of the tube so that the housing is held in place.
