Abstract
Abstract A mechanism for attaching the protective bar (1) of a baby carriage to the armrest bars (2) thereof. The mechanism includes fitting juts (3) respectively provided in the armrest bars at opposite ends thereof and engaged in fitting holes (5) provided in the protective bar and engagement bolts (4) rotatably inserted into the bolt holes (11) of the armrest bars and into the bolt holes (61) of the juts so that the protective bar is detachably attached to the armrest bars. Each of the bolts has a head (41) at a butt end thereof and an engagement pin (43) at an opposite tip end of the bolt so that the longitudinal axis of the pin is substantially perpendicular to the longitudinal axis of the bolt. Each of the bolt holes (61) has peripheral openings at one end thereof so that the pin can be passed through the openings and each of the juts has projections (63) at the peripheral portion of the bolt hole (61) near the other end thereof so that the projections are engaged with the pin to hold the bolt. Finally, each of the juts has notches between the projections so that the positions of the notches correspond to those of the openings and the pin can be passed through the notches.
