摘要

The childs push chair has a frame with a tube (1) having a longitudinal slide (2) with a bore (3) to fit onto the tube and a second longitudinal guide (4) to receive the end of a second tube (5) which forms a pivotable part of the frame. In the operative position, the slide engages the ends of both tubes to rigidly connect them, and in a second position, the slide is released from the second tube. In the first position, the slide can be held by a locking screw or catch to the two tubes.
