Abstract: A play yard has a pair of members that are spaced apart and arranged in a longitudinal direction and has a central coupling member located in a central portion in the longitudinal direction and pivotally coupled to the pair of members. One lock mechanism operates so that one of the members is not allowed to pivot with respect to the central coupling member. Another lock mechanism operates so that the other member is not allowed to pivot with respect to the central coupling member. A lock operation mechanism simultaneously unlocks both lock mechanisms to maintain them in the unlocked state.

Abstract: Provided is a foldable baby carriage having a simultaneous brake mechanism enabling the baby carriage to stand upright by itself in a folded state. A simultaneous brake mechanism includes: right and left wheel restricting members capable of switching between a brake position where the right and left wheel restricting members contact the right and left wheels and a released position where the right and left wheel restricting members are separated from the right and left wheels; and a coupling mechanism placed between the right and left wheel restricting members, for simultaneously switching the positions of the right and left wheel restricting members.

Abstract: A refill film for a waste disposal apparatus includes: a film annular body that is formed by a long tubular film folded so as to be compressed in an extending direction thereof; and a wrapping sheet that is made of a material capable of being cut, and wraps the film annular body while keeping a central hole of the film annular body open, and maintains the compressed state. Such a refill film is directly placed in a waste inlet of the waste disposal apparatus.
