Abstract
An opening and closing device for double doors for use in a toy, including: a base plate mounted with a housing formed with two openings and including two adjacent elongated holes; a pair of rotary plates receiving the lower ends of the doors; a spring normally biased the doors closed; a rotary lever engageable with edges of the rotary plates and provided with a magnet and an integral gear loosely fitted with and supported by a support shaft; and an operating lever, including a first end projecting from an opening formed at the side of the base plate, pivoted at its center portion and formed at a second end thereof with an arc-shaped edge including a rack engageable with the gear. When a separate doll including a magnetic substance is placed on the base plate over the rotary lever, the lever is moved upwardly and the gear engages the rack, whereupon the doors can be opened by the operating lever. When the doll is not so placed, the operating lever cannot operate the doors.
