ずれかに記載の乳母車の押棒のロツク機構。[Claims for Utility Model Registration] (1) A push rod for fixing a push rod whose lower end is rotatably connected to the baby carriage main body via a rotation shaft in a backward pushing state and a facing pushing state respectively. A locking mechanism for a push rod of a baby carriage, which is swingably attached to the push rod via a connecting shaft and has a first locking recess and a second locking recess at a position sandwiching the connecting shaft therebetween. a spring biasing the lock lever so as to return it to a neutral state; and a spring erected on a rear portion of the baby carriage body, the push rod being positioned in a backward pushing state and the lock lever being in a neutral state. a first locking pin that, at some point, engages with the first locking recess to fix the push rod in the back-pushing state; and a second locking pin that engages with the second locking recess when the lock lever is in a neutral state to fix the push rod in a facing state. (2) the spring is arranged to connect the rotation shaft and the lower end of the lock lever;
A locking mechanism for a push rod of a baby carriage as set forth in claim 1 of the utility model registration claim. (3) The lock lever includes the first locking pin before the first locking recess and the first locking pin engage with each other when the push rod is switched from the face-to-face pushing state to the back-facing pushing state. A first guide surface is formed that contacts the lock lever and swings the lock lever against the force of the spring to automatically bring the first locking recess and the first locking pin into an engaged state. ,
A locking mechanism for a push rod of a baby carriage according to claim 1 or 2 of the utility model registration claim. (4) The lock lever is provided with a second locking pin before the second locking recess and the second locking pin engage with each other when the push rod is switched from a back-pushing state to a facing-pushing state. A second guide surface is formed that contacts the lock lever and swings the lock lever against the force of the spring to automatically bring the second locking recess and the second locking pin into an engaged state. ,
A locking mechanism for a push rod of a baby carriage according to any one of claims 1 to 3 of the registered utility model claims.
