ABSTRACT:
A baby carriage handle support, including rotatable arms which fix the handle in upright position when the arms are aligned, uses an interlock which slides along the first arm until the second arm is inserted to the interlock support structure. The interlock support structure includes not only the usual end stop for the second arm, but also a channel projection at right angles to the stop which inserts to the channel of the second arm to provide a more positive locking relationship for the alignment of the two arms.
