TOY "SPACECRAFT" Russian patent published in 2013 - IPC A63H33/00 

FIELD: games.

SUBSTANCE: invention relates to developing games and visual aids used for demonstration purposes. Each of the spacecraft housings is made with a through screw hole and is fixed on the screw axis of the outer unit made of transparent material to form a pair of screw-nut with screw axis of the outer housing with the ability to move along it with propulsion it rotational movement with the nut. The nut is secured against rotation with one of the known methods, for example by means of a pin. In the side surfaces of the outer housing the grooves are made into which the protrusions enter, which are located on the side surfaces of the inner housings. The outer housing has a shape of a flat parallelepiped with rounded corners. Screw axes on which the inner housings are mounted are located in the outer housing in parallel and are in one plane at equal distances from one another. The grooves into which the projections enter are located on the side surfaces of inner housings, are located in the outer housing in planes perpendicular to this plane.

EFFECT: simplifying the design and improving manufacturability.
