1. Field of the Invention
The present invention relates to the field of take apart puzzle which are puzzled formed into given shape and which is assembled by combining several separate components of the puzzle. When the component are separated from each other so that the puzzle is disassembled, the problem to be solved is to reassemble the puzzle into the original shape.
2. Description of the Prior Art
In general, take apart puzzles are known in the prior art. However, the present inventor is unaware of any puzzle where at least two of the components are attracted to each other by hidden magnets and the orientation of a set of magnets in at least one component can be scrambled to enhance the difficulty of reassembling the puzzle.
The present invention relates to a puzzle in the shape of a house. One class of puzzles is known by the name take-apart puzzles and the present invention is in this class, but with a difference.
The present invention comprises a small number of bricks which when brought into close proximity with each other, make up the basic shape of a house. Once the bricks of the present invention are taken apart from each other, the puzzle solver will have the greatest of difficulty in returning the bricks back to their original configuration, even if the puzzle solver carefully replaces the bricks in the reverse order from which they are taken apart. This heightened level of difficulty is what makes the present invention very hard to solve even through the number of separate bricks making up the complete puzzle is quite small.
To facilitate this, the present invention proposes that sonic or all of the bricks comprising the puzzle have magnets within the body of these bricks. These magnets are hidden from the view of the puzzle-solver.
The aforesaid magnets are arranged in such a way as to hold all the bricks of the puzzle firmly together by their mutual magnetic attraction, thus making up the shape of a house when all the puzzle's bricks are brought together in the correct way.
Furthermore, one or more of the aforesaid magnets are allowed to move within the bricks in which they are housed. The movement of these magnets is brought about during or after the puzzle's bricks are completely removed from the magnetic influence of their adjacent bricks.
The movement of the aforesaid magnets results in these particular magnets taking up a different position within the bricks in which they are housed from that position in which they are in when the bricks are correctly assembled into the house shape. The different position to which these moving magnets finally come to rest within their respective bricks results in a mutual repulsion of the puzzle's adjacent bricks when those are brought into close proximity.
The aforesaid moving magnets are not allowed to return to their original positions within their respective bricks unless the puzzle-solver moves some or all in a very particular and precise way relative to the other bricks of the puzzle. Once the bricks have been moved with respect to each other in the particular way, the puzzle-solver can then proceed with the rest of the puzzle's assembly, thus returning the puzzle to its former starting position.
The present invention is a take-apart puzzle consisting of a small number of identical looking bricks which are held together by the mutual magnetic attraction of their internally hidden magnets. The puzzle is disassembled by separating the bricks from one another. Upon separation it will be found that one or more of the magnets within the bricks have moved and/or rotated thereby causing one or more of the bricks to now mutually repel one another. The bricks will not be attracted to each other, thus forcing the so-moved magnets back into their original positions. The puzzle is made all the more tantalizing to solve by the fact that magnetic fields cannot be readily seen and the puzzle only consists of a small number of separate pieces.
As the puzzle solver cannot see the magnetic fields, it will not be immediately obvious as to how the small number of bricks should be moved or placed relative to one another in order to complete the final solution to this puzzle. This fact makes the present invention's solution non-trivial, thus keeping the puzzle-solver occupied for a very long time in order to find the correct solution to this seemingly simple but very hard to solve puzzle.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
When the puzzle is correctly assembled as shown in
To solve the puzzle, the puzzle-solver first moves all the bricks away from one another as shown in
The strength of the magnetic force 4 between all of the bricks making up the puzzle is so arranged as to keep all the bricks tightly held together in their solved positions, but not so strong as to prevent the easy removal of the bricks from one another by hand.
Upon removing all the bricks of the puzzle from one another, such that the attractive magnetic forces 4 between the bricks are diminished, one or more of the magnets 5 is caused to rotate within one or more of the bricks 7 in such a way that the magnetic fields emanating from their poles are now causing a repulsive force 6 between adjacent bricks as shown in
Thus, after the complete removal of all the bricks from one another, and with one or more of the bricks now containing rotated magnets, the bricks are found to be mutually repulsed from each other and will not be able to be formed into the previously completed puzzle.
The puzzle-solver must now put the bricks through a complicated series of motions, moving the bricks relative to one another in order to return the displaced magnets back to their original locations in their respective bricks. This will thus facilitate the complete assembly of the puzzle back to its original shape as depicted in
The present embodiment of the invention may be enhanced by coloring the bricks in such a way as to depict a roof on the apex 7 and windows on the face 8 of each brick, thereby making the puzzle more closely and appealingly look like the outside of a stylized house. The coloring of each brick should be identical in every way to all of its partners so as not to give away any clues as to the final solution of the puzzle.
A more detailed description of one specific embodiment of the present invention will now be discussed.
This puzzle consists of 5 identical bricks which are held together by magnet attraction to form the shape of a house. Each brick is the same shape and outward appearance as all the others.
The object of the puzzle is to separate the bricks from each other and then reassemble them again to give the shape of the house. When the bricks are assembled in the correct sequence the house can be picked up by the ‘roof brick thus showing that each brick is firmly held to the others by their internal magnets.
Assembly of the puzzle is made non-trivial by means of an internal mechanism inside one of the bricks which is ‘tripped’ on disassembly so preventing re-assembly by simply pushing the bricks together again in the order in which they were taken apart. No other additional devices are needed to complete the correct (and mysterious) re-assembly. If the correct re-assembly sequence is not adhered to, then one or more of the bricks will not be attracted to the others and will not stay in place.
The bricks may be disassembled in any order but will frustratingly not return to their original positions in the assembly without further work on the part of the puzzle solver. If magnetic fields were visible and could easily be seen then this puzzle may be a little easier to solve.
Before the correct assembly sequence is given in detail, two important bricks will be identified which form the key to the whole assembly sequence. The two bricks in question are respectively illustrated in
Bricks 20 and 30 are respectively identified by the ‘filled-in’ flower 22 and 32 as shown, whereas the pattern on bricks 40, 50 and 60 is symmetrical as shown in
Step 1: Correct assembly of the house is first brought about by the identification of bricks 20 and 30.
Arranging these two bricks with their ‘filled-in’ flowers aligned as shown
Step 2: The two bricks have automatically snapped together into the correct position under their combined magnetic attraction. One of the windows should be completely visible on each brick.
Step 3: As illustrated in
Step 4: With the additional brick 40 held magnetically in place next to bricks 20 and 30 as shown in
Step 5: As illustrated in
Step 6: The additional brick 40 may now be removed to a distance thus leaving bricks 20 and 30 assembled as shown and held together by their mutual magnetic attraction, as illustrated in
Step 7: Putting aside bricks 20 and 30 for the moment, the remaining three bricks have now to be assembled as shown in
Step 8: As illustrated in
Step 9: The completed house, correctly assembled, will allow the puzzle solver to lift up the assembled house by the top ‘roof brick thus showing that all the pieces have been placed in their proper positions. No other sequence of assembly steps will allow this to be carried out as one or more of the magnets in some of the bricks will repel their adjacent bricks thereby allowing the house to fall apart if the above assembly sequence is not adhered to.
The puzzle's prototype, being made from wood, necessitated that the magnets be sunk and glued beneath the surface prior to the paint finish being applied—although a modern plastic construction would allow other more advanced fixings and efficient finishing techniques more closely compatible with mass production. As illustrated in
All the magnets' positions are hidden from view by being sunk beneath the actual surfaces of the bricks.
Their locations are carefully placed so as to ensure that they coincide with the positions of the other bricks' magnets when the bricks are brought together.
The following photographs and detailed descriptions illustrated in
The orientation of the mechanical diagrams is so arranged as to be looking inside brick 30 as though the brick was transparent.
Note that the ‘filled-in’ flower marker is at the far end of the brick and this will remain so throughout the following explanation.
The internal mechanism of brick 30 (shown in
Carrier B has four magnets 120, 130, 140 and 150 attached. Two of these magnets 120 and 130 are arranged with their south poles facing the top face of the brick 30 and the other two magnets 140 and 150 face the angled sides of the brick 30, the orientations of which are as shown in
All the magnets on both carriers are so positioned to be as near to the inner wall of the brick without actually coming in contact with its inner surface, so allowing free movement of the carriers about their axes.
Carrier A has a lever 80 attached, the far end of which 82 contacts Stop 1—number 160 on Carrier B. This lever 80 prevents Carrier B from rotating clockwise when Carrier A's magnet has not been attracted by an additional brick being placed at the end of brick 30, as in assembly step 3 detailed in Magnetic House Building Puzzle.
Stop 2 (number 170), diametrically opposite, likewise prevents Carrier B from rotating counterclockwise past its initial “unset” position as shown. Carrier B is kept hard up against this stop by the energy of the pre-tensioned helical spring 70, one end of which 72 is anchored to the pivot 74 and the other end to the brick 30.
When assembly step 3 is carried out by placing an additional brick at the correct end of brick 30, the magnet on Carrier A is attracted to the end of the brick so moving its lever 70 away from Stop 1 as shown in
Upon completion of assembly step 5, the mechanism will be in the position as shown in
This enables further assembly of bricks 40, 50 and 60 which would not be correctly attracted to brick 30 had the magnets not exchanged sides.
When the additional brick 40 is moved away from brick 30 during assembly step 6, Carrier A will return to its original position, so awaiting the sprung counter-clockwise motion of Carrier B when bricks 20 and 30 are disassembled once more (Stop 1 easily ratchets past the end of Carrier A's lever).
Carrier A does not need a return spring to keep it in its original position, as this is facilitated by the residual attraction of the adjacent magnets within the brick.
