CZ2013254A3 - Three-armed hollow cross with six interpenetrating modules - Google Patents

Abstract

The three-armed hollow cross with six penetrating modules consists of a body (1) of a three-armed hollow cross in the form of a cube, in the center of which six wire baskets (4) of the movable modules (2) penetrate. The three-spoke hollow cross with six moving penetrating modules can be used as a fun logic puzzle.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The present invention is based on a hollow three-armed cross assembly, in which a square profile cavity is capable of sliding six movable modules from six sides against each other. Only when the modules are inserted in the given order, is it possible for these modules to penetrate into each other in the center of the cross cavity.

Each of the movable modules is comprised of a guide cube into which a wire basket is attached. The guiding solid cube is the same size for all modules and defines the movement of the module in the cavity of the cross.

The wire basket consists of a wire of small cross-section to define the five sides of the cube and its edge, respectively, and the sixth side is attached to the guide cube. The wire basket is differently sized for each module. Their size is scaled from the smallest to the largest so that the wire baskets can fit together, that is, the smaller basket will penetrate the larger basket each of its five sides. In this way, we can put together all six wire baskets at any time from all six sides of an imaginary cube only by stacking them in the order of largest to smallest.

The function of the whole assembly can be illustrated by the example of using a three-armed cross with movable modules as a logic puzzle.

Let us have a solid cube, inside of which there is a cavity in the shape of a three-armed cross, whose arms open at each of the six sides of the cube. The profile of the thus formed hollow guide channels is square and meet with each other in the center of the cube. The body of the cube 1 with guide channels is shown in Fig. 2.

The movable wire basket modules are mounted in all six guide channels so that a portion of the guide cube 3 of the movable module 2 protrudes from the side of the cube body 1, as shown in Fig. 1. A cross-section of this assembly is shown in Fig. 3.

Locking and spring mechanisms must be added to the fixed cube body 1 and each of the movable modules 2 so that the movable module can only be in the two locked positions - "retracted" and "retracted". In the "extended" position, the movable module will project outward from the side of the cube. In the "retracted" position, the movable module is aligned with the side of the cube. For the sake of better clarity of the essence of the proposed puzzle, the corresponding locking and spring mechanisms, including the pressing mechanism for the possibility of inserting and releasing the movable module from the inserted position, have been omitted from the description.

The task of the puzzle solver is to gradually move the movable modules 2 so that all six are in position and the cube body is smooth without the protruding movable modules 2, as shown in the section in Fig. 4. This is only possible if they are movable the modules (2) are inserted in the correct order from the largest to the smallest. Since the solver does not know the size of the individual modules, the graduated portion of which is inside the solid cube body, they must logically derive their size by gradually inserting and ejecting the modules.

If the insertion of the modules is chaotic, it is very unlikely that this task will be solved. The number of possible module insertion variants is equal to n factorial, ie the factorial of the number of movable modules:

6! = 720

The guide cube portion may be provided with a multicolored removable portion that will protrude from the side of the solid cube body when the movable module is extended. This will allow interchangeability of the removable parts of the movable modules with each other and thus the repeatability of the solution of the puzzle problem by the same investigator.
