Abstract
A take apart wooden toy puzzle which, when assembled resembles a San Francisco cable car. The toy comprises a number of pieces, the majority of which comprise pairs of mirror image constructed pieces which align and are mutually interacting. Two key element pieces must be detected and removed from the puzzle in the correct order in order to disassemble the puzzle. The first set of these elements, the brake posts, must be removed. At this point, the cable car is able to roll upon its wheels without falling apart. Since this initial procedure leaves the toy intact, the next element to be removed is not easily ascertained. The next step consists of disengaging the second step of key elements, the tie posts, which are fitted top to bottom through the puzzle. Once the tie posts are removed, the toy is easily and quickly disassembled. When it is desired to assemble the toy, it is conducted in the reverse order of disassemblage. The pieces of the puzzle are held in place until the tie posts are inserted. The brake posts are then fitted until they engage the tie posts, thereby locking the puzzle in its final position.
