Connecting structure between push rods and push rod-connecting rod in baby carriage

A connecting structure for a baby carriage disposed between two push rods (1) for maintaining said push rods at a predetermined spacing when the baby carriage is opened and for narrowing said spacing when the baby carriage is closed, comprising a push rod-connecting member (7) connected between said push rods (1), said push rod-connecting member being foldable at least in one place in its central portion whereby a folding and unfolding action changes said spacing between said push rods (1), a pair of brackets (16) extending inwardly from said push rods (1), a pair of turning shafts (17) provided on said brackets (16), a pair of sockets (18) held by said turning shafts (17) for tilting said sockets relative to said brackets (16), said push rod-connecting member (7) having ends received in said sockets for permitting a rotating movement of said push rod-connecting member around the longitudinal axis of said push rod-connecting member (7), a pair of engaging sections (19) rigidly secured to said push rods (1) at positions opposed to the lateral surfaces of the ends of said push rod-connecting member (7), and a pair of lock control sections (20) secured to the ends of said push rod-connecting member (7) for rotation with said push rod-connecting member (7), each of said lock control sections having an abutting portion (22) of relatively large radius and a clearing portion (23) of relatively small radius, said turning shafts (17) being so spaced from the respective one of said engaging sections (19), that in one rotated position of said push rod-connecting member (7) said abutting portions (22) are brought to positions opposed to said engaging sections (19) for locking said push rod-connecting member (7) against folding, and so that in another rotated position of said push rod-connecting member said clearing portions (23) are brought to positions opposed to said engaging sections (19), whereby said clearing portions (23) clear said engaging sections for folding said push rod-connecting member (7) around the axes of said turning shafts (17).
