Toy linkage

摘要

A toy is constructed to include two unique linkages with the first linkage including a series of links located in a sequential array with each link pivotally connected to its next immediate adjacent neighbor and every other link operatively connected such that each link can pivot with respect to its neighbor and motion of a link pivotally connected to one side of a link is communicated to the link pivotally connected to the other side of that same link. This allows the linkage to propagate motion along the totality of the sequence in response to movement of any one link. The second linkage includes a first member which is pivotally connected to a rotating crank pin and connected at its upper end to a second lever which is pivotally connected to a body on which the crank pin rotates. A third member formed as a bell crank is pivotally connected at the junction of its arms to the other end of the first member and pivotally connected at the end of one of its arms to a fourth member which is also pivotally connected to the body. Movement of the crank pin causes movement of the first member which is transmitted to the remainder of the members with the lower end of the first member moving in a first small orbit and this motion being communicated to the lower end of the third member to move it in a larger orbit.
