Abstract: A toy that can be assembled by a child. At least one first block element consisting of a rod made of a flexible material including a fitting terminal at one end or opposite ends thereof is provided. The fitting terminal has at least one fitting projection thereon. A second block element has a plurality of fitting holes each adapted to be fitted onto one of the fitting projections. The first block element and the second block element are combined with each other during an assembling operation so as to exhibit a desired three dimensional configuration. Each fitting terminal is provided with a plurality of fitting projections projecting from the outer surface of the fitting terminal so that the fitting projections can be selectively fitted into one of the fitting holes on the second block element. The rod constituting the first block element is composed of a plastically deformable core and a flexible sheath molded of a soft synthetic resin surrounding the core.

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.
