摘要:
A greeting card having mechanically actuated moving portions is provided. The greeting card may include a panel having one or more folds, one or more flexible drive shafts coupled to the panel and having a flipping or moving portion, and a decorative portion coupled to at least one of the panel and the flipping or moving portion. Each flexible drive shaft may be coupled to the panel such that a portion is positioned on a first side of the fold and a portion is positioned on a second side of the fold. When the greeting card is opened, a moment arm is created in the flexible drive shaft which causes the flipping or moving portion to move from a first position to a second position. The decorative portion may move in response to the flipping or moving portion moving from the first position to the second position.
