1. Field of the Invention
This invention relates to a brain twister having flat elements movable relative to each other and arranged as an envelope on a ball-shaped inner construction.
2. Related Art
Brain twisters are special toys which aim to exercise imagination and combination skills. Brain twisters are constructed as groups or arrangements of elements movable relative to one another. These elements are usually painted with various colors on their surfaces, or printed with segments of a picture. The task of the user is to arrange a geometrical shape or picture by displacement of these elements to “solve” the brain twister. The elements can usually be displaced either individually or in rows or groups.
A typical example of a brain twister is a flat toy created by a frame in which square flat elements are placed. In the frame, there is an additional empty square to enable displacement of one or more of the flat elements in the empty space to allow rearrangement of the elements. However, this is a relatively simple toy for small children and does not attract older children or adults.
A more complicated brain twister is the “Rubic's cube” which was extremely popular in the early 1980's. Twenty seven (27) colored individual cubes are arranged in a 3×3×3 cube. Each of the walls of the cube represents a group of 9 cubes which can by twisted in two perpendicular planes. There are various paints or stickers on the individual cubes' surfaces and the task is solved when a complete color is formed on the sides of the entire cube. However, the Rubic's cube has a disadvantageous angular shape and the construction of the cube is relatively complicated.
The above mentioned insufficiencies are, to a considerable degree, eliminated by a brain twister in accordance with the present invention. The present invention includes a brain twister with a more agreeable shape, without sharp edges and sufficiently complicated to attract older children and adults by the possibility of creating pictures or images.
Movable or orbital elements are arranged into groups of at least three mutually separated and mutually movable elements. The movable elements are movable in a group about a point in the scope of 360°. The movable elements are arranged symmetrically around an additional central element to form the group. At least one of the orbital elements of each group is also a part of an adjacent group. All of the movable elements of the brain twister create an infinite and closed chain in all directions. The elements are arranged into a shape of a ball or other curved surface.
In a preferred embodiment, there are five orbital elements and one central element in a single group. The central elements are substantially flat and have a shape of a pentagon, and the orbital elements are substantially flat and have a shape of a hexagon.
Preferably, the central flat elements are firmly mounted on a ball-shaped inner construction and the movable elements are arranged around the central elements.
Preferably, the central elements have smaller real or imaginary diameters than the movable elements.
Further features and advantages of the invention, as well as the structure and operation of various embodiments of the invention, are described in detail below with reference to the accompanying drawings.
The foregoing and other features and advantages of the invention will be apparent from the following, more particular description of a preferred embodiment of the invention, as illustrated in the accompanying drawings wherein like reference numbers generally indicate identical, functionally similar, and/or structurally similar elements.
A preferred embodiment of the invention is discussed in detail below. While specific exemplary embodiments are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations can be used without parting from the spirit and scope of the invention.
A brain twister 1 in accordance with the present invention is preferably spherical, but for illustration purposes,
An advantageous embodiment of the brain twister 11 is shown in
In both of the above embodiments, each of the orbital elements of a particular group is also a part of an adjacent group of elements, which also includes orbital elements and one central element. All the movable elements create an infinite and closed chain movable in all directions, and the chains are arranged into the ball-shaped envelope carried on the ball-shaped inner construction.
The stationary elements 23 are pentagons and the orbital elements 24 appear to be hexagons. The orbital elements 24 are actually triangular with extensions 27 that form the three corners of the triangular structures 24. The extensions 27 are arranged underneath the stationary elements 23 to secure the orbital elements 24 on the ball structure 25. The extensions 27 enable the orbital elements 24 to orbit completely around the stationary elements 23. During rotation of the orbital elements 24, the stationary elements 23 also extend over a portion of the sides of the elements. In any position of the orbital elements 24, the stationary elements 23 extend over a portion of the orbital element 24 in at least two places to ensure that the slidable element 24 is not detached from the inner structure 25.
Each of the orbital elements 24 can orbit about any of the three immediately adjacent stationary elements. Any individual orbital element 24 can occupy any orbiting position on the brain teaser by successively orbiting about the stationary elements 23 as parts of different orbiting groups.
In the preferred embodiment, there is a slight spacing between each of the orbiting elements 24. A spacing element 28 is placed between the orbiting elements to fill these spaces. Preferably, the spacing elements 28 are elongated with the ends slightly larger than the middle and have slight wings 29 in the center. The spacing elements 28 can have slight protrusions 32 which can act as positioners to ensure a proper position underneath the stationary elements. The spacing elements 28 aid in the sliding movement and can slide with the orbital elements 24. Arrows on path 33 show some of the ways the orbital elements 24 can move about stationary elements 23.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should instead be defined only in accordance with the following claims and their equivalents.
