  • Patent number: 4529245
    Abstract: A collapsible chair has a base (1) and a seat portion (2) having a seat (6) disposed above and substantially parallel with the base (1). The seat and the base are connected together by mutually foldable front legs (12), front connecting bars (25), rear legs (13), and rear connecting bars (28). If these parts are folded, the distance between the seat portion (2) and the base (1) can be reduced to achieve a collapsed state in which the dimension in the direction of the height of the chair is reduced.

  • Patent number: 4515389
    Abstract: In a collapsible baby carriage having front legs (10) and rear legs (14) adapted to pivot toward each other when the baby carriage is to be folded or collapsed, handrails or armrest (28) are provided which project forwardly from the front legs (10) of the baby carriage. Each handrail or armrest (28) has a front member (48) and a rear member (49), the rear member (49) being fixed to the front leg (10). The front member (48) is connected to the rear member (49) by a pivot pin (50) so that it can be pivoted downwardly. When the rear leg (14) moves toward the front leg (10) as the baby carriage is collapsed or folded, the front member (48) pivots downwardly in operative association with the pivoting, folding movement of the rear leg (14), whereby the handrail or armrest (28) itself is folded.
