FR2643825A1 - Three-dimensional puzzle - Google Patents

Abstract

The invention relates to a three-dimensional puzzle of the brain-teaser type, comprising several elements which have to be assembled together in order to constitute a specific shape. The invention is composed of a solid of any shape defining the outer shape of the game, of any number of cylinders traversing the solid, intersecting (except for the first), or being intersected by (except for the last), at least one of the other cylinders without the creation of a notch in the intersecting cylinder. In order to prevent any accidents, the edges or corners forming an acute angle are chamfered. The solid defining the outer shape of the game may be removed in order to retain only the set of cylinders.

Description

The present invention relates to three-dimensional puzzles of the "headache" type comprising several elements which must be assembled together to constitute a single determined geometrical shape. This type of game uses qualities of visual memory and reflection and develops such qualities in the individual.

The games that are generally found on the market consist of parallelipiped elements on which it has been practiced notches generated by parallelipipeds.

These notches require complex and precise machining and, on the other hand, the game must be assembled before being put on sale, resulting in an overkill. Finally, when we want to increase the complexity of the game by increasing the number of pieces, in addition to the drawbacks mentioned above, we must face an increased design difficulty.

The present invention consists of: a) a solid defining the external shape of the set b) of cylinders passing through the solid, cutting (except the first), or being cut by (except the last) at least one of the other cylinders without creation notch in the occupant cylinder. To avoid possible accidents the edges or corners forming an acute angle are chamfered.

The solid defining the external shape of the game can have any geometric shape or any other shape, it can receive any number of cylinders
The solid defining the external shape of the game can be removed to keep only the set of cylinders.

The present invention is illustrated, without limitation, by the attached sketches representing (fig.l) a perspective view of a solid (rep.) In which cylinders are mounted in their final position Crep.1 to n) and (fig. 2 to) a perspective view showing the appearance of each cylinder bearing the same references as in fiv. 1.

The assembly of the game thus represented is done by threading the cylinders, the difficulty of the puzzle consists of threading not only a cylinder in the corresponding hole, but also in the right order,
The present invention is capable of industrial applications in the field of patience games, but can also serve as knots for assembly by dowels of three-dimensional structures, the last ankle alone having to be blocked, all the others blocking each other.

Claims (3)

1. Three-dimensional puzzle whose elements must be joined together to form a specific shape characterized in that it consists of: a solid (rep.) Defining the external shape of the game, and a set of cylinders (rep.l to n) passing through the solid, each cutting cylinder (except the first rep.l), or being cut by (except the last rep.n) at least one of the other cylinders without creating a notch in the cutting cylinder . 2. Puzzle according to claim 1. characterized in that the edges or corners forming an acute angle are chamfered.  3. Puzzle according to claim 1. characterized in that it consists only of all the cylinders (rep.l to n).
