Definitions
- the invention relates to a three-dimensional self-supporting puzzle game, with a plurality of in the assembled state a hollow body resulting puzzle pieces, each of which an outside of the hollow body associated upper side, one of the inside of the hollow body associated underside, extending between the top and the bottom edge and has at least one extending from the edge connecting region in the form of a recess or an extension.
- self-supporting is meant here that after assembly of the puzzle pieces resulting hollow body has no separate support structure on which the puzzle pieces are to be attached or on which they are supported. Rather, the hollow body is exclusively formed by the assembled puzzle pieces which, in the assembled state, give a sufficiently stable bond.
- a spherical self-supporting puzzle of the type mentioned is from the EP 1 371 401 A1 known.
- the invention has for its object to remedy this situation and to provide a three-dimensional self-supporting puzzle, the puzzle pieces can be composed without difficulty and give a player when assembling the feeling of an exact fit.
- puzzle pieces that together should form a corner may be provided with an edge along the corner that mates with the associated edge of a puzzle piece adjacent to the corner.
- the puzzle piece edge is beveled in the area of the corner.
- DE 603 00 658 T2 discloses a spherical puzzle with puzzle pieces with convex curved top The puzzle piece edge of each puzzle piece extends radially, so that the thickness of each puzzle piece is tapered.
- the course of the facing edges of the adjoining puzzle pieces between the top and the Bottom is defined by the bisector of a surface angle formed between two straight lines which intersect on the bisecting line and from an upper end point of the associated one of the facing edges of the two adjoining puzzle pieces to an upper end point of an opposite edge of the same puzzle piece and, in the case of a convexly curved top puzzle piece, to a first maximum in the opposite direction Edge of the same puzzle piece run, and that in the connecting region, the circumference of an edge of each extension is at most the same size as the smallest circumference of an edge of an adjacent puzzle piece with a respective extension corresponding recess.
- facing edges is meant here only the edge portions of the puzzle pieces that are not associated with a connection area. It is a characteristic of the present invention that a distinction is made between the edge regions associated with a joint region and the remainder of the edge of a puzzle piece, because due to the intentionally smaller circumference of each extension (as compared to the corresponding recess), one is in the joint regions free to make the edge different there than the rest of a puzzle piece.
- the slightly smaller circumference of an extension is to be understood as meaning that in the connection region the edge of an extension does not touch the edge of a corresponding recess or, in the case of special embodiments described below, contacts it only in defined manner. Conventionally, however, the edge of an extension was designed so that it fits exactly in the corresponding recess, that is usually more or less continuously applied to the opposite edge of the recess.
- spherical puzzle it is advantageous to modify the shape of the mutually facing edges obtained with the design rule explained above, in order to further improve the ability to puzzle. Therefore, preferred embodiments of spherical jigs are made of puzzle pieces whose facing edges do not run parallel to each other in the thickness direction of the puzzle pieces, but separate from each other from top to bottom.
- the deviation from the edge parallelism is preferably at least five degrees in total, ie the edge course deviates for each puzzle piece of the other puzzle piece facing edge by at least 2.5 degrees in the manner described by a parallel course.
- the puzzle of the invention is not limited to the spherical shape, but may in the assembled state a cube, a pyramid, a cuboid, a cylinder, a body with elliptical cross-section, such as an egg-shaped body, or combinations of the aforementioned bodies.
- hollow bodies are possible which can not be assigned to any of the aforementioned basic geometrical bodies, for example heart-shaped hollow bodies, animal-shaped hollow bodies and the like.
- the resulting hollow body need not be closed on all sides, but may have at least one open side. Cup, bowl and vase-shaped hollow bodies are mentioned here as examples.
- the resulting hollow body can represent almost any object, such as a known building or the like.
- the individual puzzle pieces can be flat or curved or arched, or curved several times. If the individual puzzle pieces are small in comparison to the curvature of the entire hollow body, then a hollow body with curved or curved surfaces can also be composed of flat puzzle pieces, which due to their comparatively small size closely approximate the curved shape. Only the extensions of the puzzle pieces need to be slightly angled in such a case.
- puzzle games according to the invention may comprise planar and curved puzzle pieces, certain puzzle pieces may also include one or more body edges, for example the tip of a pyramid or the corners and edges of a cube or cuboid.
- the puzzle pieces may be substantially the same size, but may be different in size.
- Each puzzle piece may have a plurality of connecting portions, wherein the connecting portions themselves may be the same or different from each other.
- the puzzle pieces can accommodate the basic shape of the hollow body which results in the assembled state, i. Essentially square puzzle pieces can form a cube, essentially hexagonal puzzle pieces can form a hexahedron, etc.
- the course of the mutually facing edges between the upper side and the lower side is determined is defined by the bisector of the face angle formed between the two bisectors intersecting the bisector, which extend from an upper end point of the associated one of the facing edges to an upper end point of an opposite edge of the same puzzle piece, or if it is a convex curve Jigsaw piece acts to extend to a first maximum in the direction of an opposite edge of the same puzzle piece is guaranteed for hollow body almost any shape that the respective mutually facing edges of the puzzle pieces can exactly abut each other.
- the design rule of the edge profile according to the invention results in a firm and yet easily releasable press connection. Because the edge of the puzzle piece main body, ie the puzzle pieces without the connecting areas, forms the overwhelming portion of all visible dividing lines in the finished hollow body, an exact matching of these edges leads to a qualitatively much higher appearance of the assembled hollow body.
- improved peripheral playability ensures that, according to the invention, the circumference of the edge of each extension is slightly smaller than the circumference of the edge of a recess corresponding to a respective appendage in an adjacent puzzle piece.
- This feature ensures that the connecting portions of adjoining puzzle pieces can be inserted into one another from above as well as from below, because the circumference of the edge of an extension is at most the same size as the smallest circumference of the edge of a recess in the adjoining puzzle piece corresponding to this projection .
- maximum the same size is meant an equally large one in compliance with customary dimensional tolerances, ie there is no contact between an extension and the corresponding recess in the connection area.
- each extension is preferably formed so that its upper peripheral edge is smaller than the lower peripheral edge of the associated recess. Projections and recesses may be identically formed in the puzzle pieces or, as is typical for puzzles, recognizably different from each other.
- the puzzle pieces can have an equal or different number of recesses or extensions. Puzzle pieces can also have extensions and recesses.
- edges of the extensions and the recesses need not be perpendicular to the top or bottom of the puzzle piece when viewed in cross-section, i. the edge course seen over the cross section need not be normal to the top and bottom, but may be inclined to the top and bottom.
- the edge of an extension and the corresponding edge of a recess from the top to the bottom of each other can be removed, similar to what has been previously explained in connection with the mutually facing edges of the puzzle pieces.
- each extension can be inserted into a corresponding recess both from above and from below.
- At least one projection protruding from the edge of the recess or from the edge of the extension is in discontinuous contact with the opposite edge of the extension or recess.
- discontinuous contact it is meant here that the protrusion protruding from the edge of the recess or extension does not contact the respective opposite edge along the entire edge of the connection area.
- the protrusion according to the invention should therefore not be a rib extending along the entire connecting region.
- the discontinuous contact is an approximately punctiform contact, i. the protruding projection is designed so that it touches the opposite edge in the connection area only approximately punctiform, but a short line-shaped contact is also possible.
- a plurality of protruding projections may be provided for each connection area.
- the recess is usually an undercut recess
- the projections may extend from the edge of the recess or from the edge of the extension, but it may just as well extend a projection from the edge of the recess and the second projection from the edge of the extension. Also, more than two projections in the connection area are possible.
- the or each projection does not extend to the top and / or not to the bottom of the extension or recess. In this way, the protrusions from the top and / or the bottom in the assembled state of the puzzle pieces are not visible to the naked eye.
- each projection may be associated with a corresponding recess in the opposite edge of the extension or the recess. Without the corresponding recess each projection causes a preferably punctiform clamping between extension and recess in the connection area. With a corresponding depression this clamping effect also occurs, but is complemented by a palpable when assembling the puzzle pieces engagement or clicking the parts into each other, whereby the haptic quality of the puzzle process is increased. A player thus receives the feeling exactly and with defined force in each other latching puzzle pieces.
- the protrusions in the connection region provided according to the invention in preferred embodiments allow a separation of the different edge regions of a puzzle piece: the edge of the puzzle piece main body can be optimized for accuracy of fit and need not provide clamping, while the connecting region is in the direction of simple top-to-bottom composability while providing preferably punctiform clamping effects can be optimized.
- the projections according to the invention can be provided only in critical areas of the puzzle or anywhere. In the latter case, the entirety of all protrusions preferably forms a contact point network spanning the lateral surface of the hollow body, which additionally stabilizes the assembled hollow body.
- the edge between the top of the or each extension and its edge and / or the edge between the bottom of the or each extension and its edge may be made more or less rounded. In this way, sharp edges are avoided and it is, especially on the outside of the hollow body, provided for the typical appearance of a puzzle. Similarly, the edge between the top of the or each recess and its edge and / or the edge between the bottom of the or each recess and its edge may be made more or less rounded.
- edges between the top of each puzzle piece and its edge and / or the edges between the bottom of each puzzle piece and its edge may be made more or less rounded. It is also possible to combine not rounded edges, in particular on the upper side of the puzzle piece, with rounded edges of the extensions and / or recesses. Such a design leads to a very high-quality because almost closed hollow body surface yet puzzle.
- the individual puzzle pieces can advantageously be produced from plastic by injection molding.
- FIG. 1 shows an example of a puzzle piece 10 with a top 12 and only in the sectional view of FIGS. 2 to 4 visible underside 14. Between the upper side 12 and the lower side 14 extends a defined by the material thickness of the puzzle piece 10, peripheral edge 16, from which here two marked by dashed lines connecting portions 18 extend.
- One connecting region 18 has the shape of a recess 20 extending into the puzzle piece 10, while the other connecting region 18 has the shape of an extension 22 extending away from the puzzle piece 10.
- peripheral around the puzzle piece 10 edge 16 is not part of the connecting portions 18, only the belonging to a recess 20 or an extension 22 edge portions are attributable to the respective connection region 18.
- Each recess 20 and each extension 22 corresponds in an adjoining puzzle piece a correspondingly formed extension or a correspondingly formed recess, so that two adjoining puzzle pieces 10 can be connected to each other by joining the connecting portions 18 together. It is understood that a plurality of recesses 20 and / or extensions 22 can be present on a puzzle piece 10 and that their shape can be different in each case.
- a plurality of puzzle pieces 10 the appearance of which may be different from one another, results in a hollow body such as a cube, a sphere, a pyramid, an octahedron, a cuboid, a heart, a bear or other animal, or even a building ,
- a hollow body such as a cube, a sphere, a pyramid, an octahedron, a cuboid, a heart, a bear or other animal, or even a building
- the course of their facing edges 16 between the top 12 and the bottom 14 is fixed at two adjoining puzzle pieces 10 by an angle bisector ⁇ of a surface angle ⁇ , which is formed between two straight lines ⁇ and ⁇ (see FIGS. 2 to 4 ).
- the straight line ⁇ extends from an upper end point 24 of the in FIG. 2 left puzzle piece 10 associated edge 16 of the two mutually facing edges 16 to an upper end point 26 of an opposite edge 16 thereof, in FIG. 2 the left-hand puzzle piece 10.
- the straight line ⁇ runs from an upper end point 28 on in FIG FIG. 2 right puzzle piece 10 to an upper end point 30 of the same puzzle piece.
- the two straight lines ⁇ and ⁇ defined by the upper end points 24 and 26 as well as 28 and 30 form the surface angle ⁇ between them and intersect on the bisector ⁇ of this surface angle ⁇ .
- the mutually facing edges 16 of the two puzzle pieces 10 follow between the top 12 and the bottom 14 of the associated puzzle piece 10 of the bisector ⁇ .
- FIG. 3 is a section through two contiguous, curved puzzle pieces 10 of different size reproduced.
- the course of the mutually facing edges 16 between the top 12 and the bottom 14 of the associated puzzle piece 10 is determined by two straight lines ⁇ and ⁇ , which as described above emanate from the upper end point 24 and 28 and in deviation from FIG. 2 extend to a maximum 32 on the convexly curved top 12 in the direction of an opposite edge 16 of the same puzzle piece.
- the angle bisector ⁇ of the surface angle ⁇ formed between the two straight lines ⁇ and ⁇ in turn determines the course of the mutually facing edges 16 between the tops 12 and the bottoms 14 of the puzzle pieces 10.
- curved puzzle pieces 10 do not necessarily have to have a constant radius of curvature over their entire extent and may even be curved in opposite directions over their extension, it is advantageous to define the straight lines ⁇ and ⁇ by the maximum 32 closest to the mutually facing edges 16 on the upper side 12 of curved puzzle pieces 10.
- FIG. 4 shows a section through two adjacent puzzle pieces, of which the left puzzle piece 10 is curved and the right puzzle piece 10 is flat.
- the straight line ⁇ is determined in accordance with FIG FIG. 3 in the case of the flat puzzle piece 10, on the other hand, the straight line ⁇ is determined in accordance with FIG FIG. 2 ,
- the edges 16 of virtually any shape puzzle pieces 10 can be set so that always an exact and well together supporting fit between the puzzle pieces is guaranteed.
- the mutually facing edges 16 of the individual puzzle pieces 10 can be assembled at its top 12 almost gap-free, while resulting in each case two puzzle pieces 10 an inwardly increasing gap.
- the deviation from the edge parallelism is at least five degrees in total, i.
- edge course of the edge facing another puzzle piece 10 deviates from a parallel course by at least 2.5 degrees in the described manner. It should be noted here that the edge 16 is only the edge of the puzzle piece main body that the previously stated design rules do not apply to the located in the connecting areas 18 edge.
- FIG. 5 which shows in plan view an enlarged view of two mutually inserted connecting portions 18 of two adjoining puzzle pieces 10, the design rule for the edges of the connecting portions 18 will now be explained.
- a small gap 34 which results from the fact that in the connecting region 18, the circumference of an edge 36 of each extension 22 is slightly smaller than the circumference of an edge 38 of the adjacent puzzle piece 10th with the extension 22 corresponding recess 20.
- the size of the gap 34 is exaggerated. In reality, the gap will be chosen so that the column 34 in the assembled hollow body does not interfere in appearance and are ideally imperceptible to the naked eye.
- FIG. 5 can be seen in the embodiment shown between two respective connecting portions 18, two projections 40 present, which here extend from the edge 38 of the recess 20 and are in approximately point-like contact with the opposite edge 36 of the extension 22. Every lead 40 is here approximately hemispherical and engages in a formed in the edge 36, dome-shaped recess 42 (see also the sectional view in FIG. 6 ).
- the two projections 40 are arranged opposite each other in the recess 20 at a position at which the undercut of the recess 20 begins. In this way, when inserting the extension 22 into the recess 20, the puzzle piece 10 provided with the extension 22 is pulled against the puzzle piece provided with the recess 20 and the mutually facing edges 16 of the two puzzle pieces 10 abut each other.
- each projection 40 is seen in the cross-sectional direction formed only in a central region of the edge 38, as well each recess 42 in the edge 36.
- the projection 40 and associated recess 42 formed, approximately punctiform detent connection is therefore from the top 12 or bottom 14th the puzzle pieces 10 practically not visible. This is true even if as in FIG. 6 shown the edges of the recess 20 and the extension 22 is not sharp, but executed rounded.
- FIG. 7 shows a plan view of a puzzle piece 10 with two opposing recesses 20 and two also opposite projections 22. In each recess 20 and on each extension 22 each two opposing projections 40 are formed at the beginning of the undercut. Substituting such trained puzzle pieces 10, results in a FIG. 8 illustrated network of contact points between the individual parts of the puzzle 10, which spans the hollow body in the assembled state of all puzzle pieces and for excellent stability at the same time very good puzzleability, ie connectivity of the puzzle pieces with each other

Description
Die Erfindung betrifft ein dreidimensionales selbsttragendes Puzzlespiel, mit einer Vielzahl von im zusammengesetzten Zustand einen Hohlkörper ergebenden Puzzleteilen, von denen jedes eine der Außenseite des Hohlkörpers zugehörige Oberseite, eine der Innenseite des Hohlkörpers zugehörige Unterseite, einen sich zwischen der Oberseite und der Unterseite erstreckenden Rand und wenigstens einen sich von dem Rand erstreckenden Verbindungsbereich in Gestalt einer Ausnehmung oder eines Fortsatzes aufweist. Mit dem Begriff "selbsttragend" ist hier gemeint, dass der sich nach dem Zusammensetzen der Puzzleteile ergebende Hohlkörper keine separate Tragstruktur aufweist, auf der die Puzzleteile zu befestigen sind oder auf der sie sich abstützen. Der Hohlkörper wird vielmehr ausschließlich durch die zusammengesetzten Puzzleteile gebildet, die im zusammengesetzten Zustand einen ausreichend stabilen Verbund ergeben. Ein kugelförmiges selbsttragendes Puzzlespiel der genannten Art ist aus der
Bei dem zuvor genannten, aus dem Stand der Technik bekannten kugelförmigen Puzzlespiel ist die Passung der einzelnen Puzzleteile untereinander verbesserungswürdig. In der Praxis variiert deshalb der Kraftaufwand, der zum Zusammensetzen der einzelnen Puzzleteile erforderlich ist, insbesondere gegen Ende des Puzzlespiels, wenn schon fast alle Puzzleteile miteinander verbunden worden sind, erfordert das Zusammensetzen der Puzzleteile eine zu große Kraft. Dieses uneinheitliche Verhalten führt beim Spieler tendenziell zur Verärgerung und erweckt darüber hinaus den Eindruck einer minderen Qualität des Puzzlespiels.In the aforementioned spherical puzzle game known from the prior art, the fit of the individual puzzle pieces with each other is in need of improvement. In practice, therefore, varies the force required to assemble the individual puzzle pieces, especially towards the end of the puzzle, when almost all pieces of the puzzle have been joined together, the assembly of the puzzle pieces requires too much force. This inconsistent behavior tends to annoy the player and also gives the impression of a lesser quality of the puzzle.
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen und ein dreidimensionales selbsttragendes Puzzlespiel bereitzustellen, dessen Puzzleteile sich ohne Schwierigkeiten zusammensetzen lassen und einem Spieler beim Zusammensetzen das Gefühl einer exakten Passung vermitteln.The invention has for its object to remedy this situation and to provide a three-dimensional self-supporting puzzle, the puzzle pieces can be composed without difficulty and give a player when assembling the feeling of an exact fit.
Aus der
Die obige Aufgabe ist ausgehend von einem eingangs genannten, gattungsgemäßen Puzzlespiel erfindungsgemäß dadurch gelöst, dass bei zwei oder mehr aneinandergrenzenden Puzzleteilen, von denen zumindest eines ein Puzzleteil mit konvex gekrümmter Oberfläche ist, der Verlauf der einander zugewandten Ränder der aneinandergrenzenden Puzzleteile zwischen der Oberseite und der Unterseite festgelegt ist durch die Winkelhalbierende eines Flächenwinkels, der zwischen zwei Geraden gebildet ist, die sich auf der Winkelhalbierenden schneiden und von einem oberen Endpunkt des zugehörigen der einander zugewandten Ränder der beiden aneinandergrenzenden Puzzleteile zu einem oberen Endpunkt eines entgegengesetzten Randes desselben Puzzleteils und, bei einem Puzzleteil mit konvex gekrümmter Oberseite, zu einem ersten Maximum in Richtung eines entgegengesetzten Randes desselben Puzzleteils verlaufen, und dass im Verbindungsbereich der Umfang eines Randes jedes Fortsatzes maximal genauso groß ist wie der kleinste Umfang eines Randes einer in einem angrenzenden Puzzleteil mit einem jeweiligen Fortsatz korrespondierenden Ausnehmung. Mit dem Begriff der "einander zugewandten Ränder" sind hier ausschließlich die Randabschnitte der Puzzleteile gemeint, die nicht einem Verbindungsbereich zugehörig sind. Es ist ein Charakteristikum der vorliegenden Erfindung, dass zwischen den Randbereichen, die einem Verbindungsbereich zugehörig sind, und dem restlichen Rand eines Puzzleteils unterschieden wird, denn aufgrund des erfindungsgemäß bewusst kleiner gehaltenen Umfangs jedes Fortsatzes (im Vergleich zur korrespondierenden Ausnehmung) ist man in den Verbindungsbereichen frei, den Rand dort anders zu gestalten als den restlichen Rand eines Puzzleteils. Der geringfügig kleinere Umfang eines Fortsatzes ist im Rahmen der vorliegenden Erfindung so zu verstehen, dass im Verbindungsbereich der Rand eines Fortsatzes den Rand einer korrespondierenden Ausnehmung nicht oder - bei im Folgenden noch beschriebenen, besonderen Ausführungsformen - nur definiert berührt. Herkömmlich wurde hingegen der Rand eines Fortsatzes so gestaltet, dass er genau in die korrespondierende Ausnehmung passt, d.h. in der Regel mehr oder weniger durchgehend am gegenüberliegenden Rand der Ausnehmung anliegt.The above object is achieved on the basis of an aforementioned generic puzzle according to the invention that in two or more adjoining puzzle pieces, at least one of which is a puzzle piece with a convex curved surface, the course of the facing edges of the adjoining puzzle pieces between the top and the Bottom is defined by the bisector of a surface angle formed between two straight lines which intersect on the bisecting line and from an upper end point of the associated one of the facing edges of the two adjoining puzzle pieces to an upper end point of an opposite edge of the same puzzle piece and, in the case of a convexly curved top puzzle piece, to a first maximum in the opposite direction Edge of the same puzzle piece run, and that in the connecting region, the circumference of an edge of each extension is at most the same size as the smallest circumference of an edge of an adjacent puzzle piece with a respective extension corresponding recess. By the term "facing edges" is meant here only the edge portions of the puzzle pieces that are not associated with a connection area. It is a characteristic of the present invention that a distinction is made between the edge regions associated with a joint region and the remainder of the edge of a puzzle piece, because due to the intentionally smaller circumference of each extension (as compared to the corresponding recess), one is in the joint regions free to make the edge different there than the rest of a puzzle piece. In the context of the present invention, the slightly smaller circumference of an extension is to be understood as meaning that in the connection region the edge of an extension does not touch the edge of a corresponding recess or, in the case of special embodiments described below, contacts it only in defined manner. Conventionally, however, the edge of an extension was designed so that it fits exactly in the corresponding recess, that is usually more or less continuously applied to the opposite edge of the recess.
Insbesondere bei einem kugelförmigen Puzzle ist es vorteilhaft, die mit der zuvor erläuterten Konstruktionsvorschrift erhaltene Gestalt der einander zugewandten Ränder noch zu modifizieren, um die Puzzlebarkeit weiter zu verbessern. Bevorzugte Ausführungsformen kugelförmiger Puzzle bestehen deshalb aus Puzzleteilen, deren einander zugewandte Ränder in Dickenrichtung der Puzzleteile nicht parallel zueinander verlaufen, sondern sich von der Oberseite zur Unterseite voneinander entfernen. Auf diese Weise kann die Puzzlebarkeit ohne eine Beeinträchtigung des Aussehens verbessert werden, denn an der sichtbaren Außenseite, also der Oberseite, können die einander zugewandten Ränder der einzelnen Puzzleteile nahezu spaltfrei zusammengefügt werden, während sich zwischen je zwei Puzzleteilen ein nach innen hin zunehmender Spalt ergibt. Vorzugsweise beträgt die Abweichung von der Randparallelität insgesamt wenigstens fünf Grad, d.h. bei jedem Puzzleteil weicht der Randverlauf des einem anderen Puzzleteil zugewandten Randes um mindestens 2,5 Grad in der beschriebenen Weise von einem parallelen Verlauf ab.In particular, in the case of a spherical puzzle, it is advantageous to modify the shape of the mutually facing edges obtained with the design rule explained above, in order to further improve the ability to puzzle. Therefore, preferred embodiments of spherical jigs are made of puzzle pieces whose facing edges do not run parallel to each other in the thickness direction of the puzzle pieces, but separate from each other from top to bottom. In this way, the ability to puzzle be improved without affecting the appearance, because on the visible outside, so the top, the facing edges of the individual puzzle pieces can be joined together almost gap-free, while there is an inwardly increasing gap between each two puzzle pieces , The deviation from the edge parallelism is preferably at least five degrees in total, ie the edge course deviates for each puzzle piece of the other puzzle piece facing edge by at least 2.5 degrees in the manner described by a parallel course.
Das erfindungsgemäße Puzzlespiel ist nicht auf die Kugelform beschränkt, sondern kann im zusammengesetzten Zustand einen Würfel, eine Pyramide, einen Quader, einen Zylinder, einen Körper mit elliptischem Querschnitt, beispielsweise einen eiförmigen Körper, oder auch Kombinationen aus den vorgenannten Körpern bilden. Ebenso sind Hohlkörper möglich, die sich keiner der zuvor genannten geometrischen Grundkörper zuordnen lassen, beispielsweise herzförmige Hohlkörper, tierförmige Hohlkörper und ähnliches. Auch braucht der sich ergebende Hohlkörper nicht allseitig geschlossen zu sein, sondern kann wenigstens eine offene Seite haben. Tassen-, schüssel- und vasenförmige Hohlkörper seien hier als Beispiele genannt. Schließlich kann der sich ergebende Hohlkörper nahezu jeden beliebigen Gegenstand darstellen, etwa ein bekanntes Bauwerk oder ähnliches.The puzzle of the invention is not limited to the spherical shape, but may in the assembled state a cube, a pyramid, a cuboid, a cylinder, a body with elliptical cross-section, such as an egg-shaped body, or combinations of the aforementioned bodies. Likewise, hollow bodies are possible which can not be assigned to any of the aforementioned basic geometrical bodies, for example heart-shaped hollow bodies, animal-shaped hollow bodies and the like. Also, the resulting hollow body need not be closed on all sides, but may have at least one open side. Cup, bowl and vase-shaped hollow bodies are mentioned here as examples. Finally, the resulting hollow body can represent almost any object, such as a known building or the like.
Die einzelnen Puzzleteile können eben oder auch gekrümmt bzw. gewölbt, auch mehrfach gekrümmt sein. Wenn die einzelnen Puzzleteile klein sind im Vergleich zur Krümmung des gesamten Hohlkörpers, dann kann ein Hohlkörper mit gekrümmten bzw. gewölbten Flächen auch aus ebenen Puzzleteilen zusammengesetzt werden, die aufgrund ihrer vergleichsweisen Kleinheit die gewölbte Form gut approximieren. Lediglich die Fortsätze der Puzzleteile brauchen in einem solchen Fall leicht abgewinkelt zu sein.The individual puzzle pieces can be flat or curved or arched, or curved several times. If the individual puzzle pieces are small in comparison to the curvature of the entire hollow body, then a hollow body with curved or curved surfaces can also be composed of flat puzzle pieces, which due to their comparatively small size closely approximate the curved shape. Only the extensions of the puzzle pieces need to be slightly angled in such a case.
Erfindungsgemäße Puzzlespiele können je nach dem im zusammengesetzten Zustand gebildeten Hohlkörper ebene und gewölbte Puzzleteile umfassen, bestimmte Puzzleteile können auch eine oder mehrere Körperkanten beinhalten, beispielsweise die Spitze einer Pyramide oder die Ecken und Kanten eines Würfels oder Quaders. Die Puzzleteile können im Wesentlichen von gleicher Größe sein, sie können aber auch unterschiedliche Größe aufweisen. Jedes Puzzleteil kann mehrere Verbindungsbereiche aufweisen, wobei die Verbindungsbereiche selbst gleich oder verschieden voneinander ausgeführt sein können. Die Puzzleteile können die Grundform des Hohlkörpers aufnehmen, der sich im zusammengesetzten Zustand ergibt, d.h. im Wesentlichen quadratische Puzzleteile können einen Würfel bilden, im Wesentlichen hexagonale Puzzleteile können einen Hexaeder bilden etc.Depending on the hollow body formed in the assembled state, puzzle games according to the invention may comprise planar and curved puzzle pieces, certain puzzle pieces may also include one or more body edges, for example the tip of a pyramid or the corners and edges of a cube or cuboid. The puzzle pieces may be substantially the same size, but may be different in size. Each puzzle piece may have a plurality of connecting portions, wherein the connecting portions themselves may be the same or different from each other. The puzzle pieces can accommodate the basic shape of the hollow body which results in the assembled state, i. Essentially square puzzle pieces can form a cube, essentially hexagonal puzzle pieces can form a hexahedron, etc.
Indem erfindungsgemäß bei aneinandergrenzenden Puzzleteilen der Verlauf der einander zugewandten Ränder zwischen der Oberseite und der Unterseite festgelegt ist durch die Winkelhalbierende des Flächenwinkels, der zwischen den zwei sich auf der Winkelhalbierenden schneidenden Geraden gebildet ist, die von einem oberen Endpunkt des zugehörigen der einander zugewandten Ränder zu einem oberen Endpunkt eines entgegengesetzten Randes desselben Puzzleteils verlaufen oder, wenn es sich um ein konvex gekrümmtes Puzzleteil handelt, zu einem ersten Maximum in Richtung eines entgegengesetzten Randes desselben Puzzleteils verlaufen, ist für Hohlkörper nahezu jedweder Gestalt garantiert, dass die jeweils einander zugewandten Ränder der Puzzleteile exakt aneinander anliegen können. Bei konvex gekrümmten Puzzleteilen ergibt sich aus der erfindungsgemäßen Gestaltungsvorschrift des Randverlaufs eine feste und dennoch leicht wieder lösbare Pressverbindung. Weil der Rand der Puzzleteilhauptkörper, d.h. der Puzzleteile ohne den Verbindungsbereichen, beim fertiggestellten Hohlkörper den weitaus überwiegenden Anteil aller sichtbaren Trennlinien bildet, führt ein exaktes Zusammenpassen dieser Ränder zu einem qualitativ deutlich höherwertigen Erscheinungsbild des zusammengesetzten Hohlkörpers.In accordance with the invention, in the case of contiguous puzzle pieces, the course of the mutually facing edges between the upper side and the lower side is determined is defined by the bisector of the face angle formed between the two bisectors intersecting the bisector, which extend from an upper end point of the associated one of the facing edges to an upper end point of an opposite edge of the same puzzle piece, or if it is a convex curve Jigsaw piece acts to extend to a first maximum in the direction of an opposite edge of the same puzzle piece is guaranteed for hollow body almost any shape that the respective mutually facing edges of the puzzle pieces can exactly abut each other. In the case of convexly curved puzzle pieces, the design rule of the edge profile according to the invention results in a firm and yet easily releasable press connection. Because the edge of the puzzle piece main body, ie the puzzle pieces without the connecting areas, forms the overwhelming portion of all visible dividing lines in the finished hollow body, an exact matching of these edges leads to a qualitatively much higher appearance of the assembled hollow body.
Für eine verbesserte Puzzlebarkeit sorgt darüber hinaus, dass erfindungsgemäß der Umfang des Randes jedes Fortsatzes geringfügig kleiner ist als der Umfang des Randes einer in einem angrenzenden Puzzleteil mit einem jeweiligen Fortsatz korrespondierenden Ausnehmung. Dieses Merkmal stellt sicher, dass die Verbindungsbereiche aneinander angrenzender Puzzleteile bezüglich einander sowohl von oben als auch von unten ineinander einführbar sind, denn der Umfang des Randes eines Fortsatzes ist maximal genauso groß wie der kleinste Umfang des Randes einer mit diesem Fortsatz korrespondierenden Ausnehmung im angrenzenden Puzzleteil. Mit "maximal genauso groß" ist hier ein genauso groß unter Einhaltung üblicher Maßtoleranzen gemeint, d.h. zwischen einem Fortsatz und der mit diesem korrespondierenden Ausnehmung besteht im Verbindungsbereich keine Berührung. Der zwischen einem Fortsatz und der korrespondierenden Ausnehmung bestehende Spalt ist allerdings so klein, dass er optisch praktisch nicht wahrnehmbar ist und somit insbesondere das äußere Erscheinungsbild des zusammengesetzten Hohlkörpers nicht negativ beeinflusst. Mit anderen Worten ist die Kantengeometrie jedes Fortsatzes so ausgeführt, dass jeder Fortsatz sowohl von oben als auch von unten in eine korrespondierende Ausnehmung einführbar ist. Bei konvex gewölbten Puzzleteilen, z.B. bei einem insgesamt kugelförmigen Puzzle, ist jeder Fortsatz vorzugsweise so ausgebildet, dass sein oberer Umfangsrand kleiner als der untere Umfangsrand der zugehörigen Ausnehmung ist. Fortsätze und Ausnehmungen können bei den Puzzleteilen identisch oder, wie dies für Puzzlespiele typisch ist, erkennbar voneinander verschieden ausgebildet sein. Die Puzzleteile können eine gleiche oder verschiedene Anzahl von Ausnehmungen oder Fortsätzen aufweisen. Puzzleteile können auch Fortsätze und Ausnehmungen aufweisen.In addition, improved peripheral playability ensures that, according to the invention, the circumference of the edge of each extension is slightly smaller than the circumference of the edge of a recess corresponding to a respective appendage in an adjacent puzzle piece. This feature ensures that the connecting portions of adjoining puzzle pieces can be inserted into one another from above as well as from below, because the circumference of the edge of an extension is at most the same size as the smallest circumference of the edge of a recess in the adjoining puzzle piece corresponding to this projection , By "maximally the same size" is meant an equally large one in compliance with customary dimensional tolerances, ie there is no contact between an extension and the corresponding recess in the connection area. However, the gap existing between an extension and the corresponding recess is so small that it is practically imperceptible to the senses and thus does not adversely affect, in particular, the external appearance of the assembled hollow body. In other words, the edge geometry of each extension is designed such that each extension can be inserted into a corresponding recess both from above and from below. For convex arched puzzle pieces, for example, in a total spherical puzzle, each extension is preferably formed so that its upper peripheral edge is smaller than the lower peripheral edge of the associated recess. Projections and recesses may be identically formed in the puzzle pieces or, as is typical for puzzles, recognizably different from each other. The puzzle pieces can have an equal or different number of recesses or extensions. Puzzle pieces can also have extensions and recesses.
Die Ränder der Fortsätze und der Ausnehmungen müssen im Querschnitt gesehen nicht im rechten Winkel auf die Oberseite bzw. die Unterseite des Puzzleteils auftreffen, d.h. der Randverlauf über den Querschnitt gesehen braucht nicht normal zur Oberseite und zur Unterseite zu sein, sondern kann zur Ober- und Unterseite geneigt sein. Dabei können sich der Rand eines Fortsatzes und der korrespondierende Rand einer Ausnehmung von der Oberseite zur Unterseite voneinander entfernen, ähnlich wie dies zuvor im Zusammenhang mit den einander zugewandten Rändern der Puzzleteile erläutert worden ist. Auch für solche Ausführungsformen des erfindungsgemäßen Puzzles gilt selbstverständlich, dass jeder Fortsatz sowohl von oben als auch von unten in eine korrespondierende Ausnehmung einführbar ist.The edges of the extensions and the recesses need not be perpendicular to the top or bottom of the puzzle piece when viewed in cross-section, i. the edge course seen over the cross section need not be normal to the top and bottom, but may be inclined to the top and bottom. In this case, the edge of an extension and the corresponding edge of a recess from the top to the bottom of each other can be removed, similar to what has been previously explained in connection with the mutually facing edges of the puzzle pieces. For such embodiments of the puzzle according to the invention, it goes without saying that each extension can be inserted into a corresponding recess both from above and from below.
Zur weiteren Verbesserung der Verbindungsqualität und Puzzlebarkeit der Puzzleteile untereinander steht bei bevorzugten Ausgestaltungen erfindungsgemäßer Puzzlespiele im Verbindungsbereich wenigstens ein vom Rand der Ausnehmung oder vom Rand des Fortsatzes herausragender Vorsprung in diskontinuierlicher Berührung mit dem gegenüberliegenden Rand des Fortsatzes bzw. der Ausnehmung. Mit dem Begriff "in diskontinuierlicher Berührung" ist hier gemeint, dass der vom Rand der Ausnehmung oder des Fortsatzes herausragende Vorsprung nicht entlang des gesamten Randes des Verbindungsbereiches in Berührung mit dem jeweils gegenüberliegenden Rand steht. Insbesondere soll der erfindungsgemäß herausragende Vorsprung also keine sich längs des gesamten Verbindungsbereiches erstreckende Rippe sein. Vorzugsweise ist die diskontinuierliche Berührung eine näherungsweise punktförmige Berührung, d.h. der herausragende Vorsprung ist so gestaltet, dass er den gegenüberliegenden Rand im Verbindungsbereich nur näherungsweise punktförmig berührt, jedoch ist eine kurze linienförmige Berührung ebenso möglich.In order to further improve the connection quality and the puzzle-ability of the puzzle pieces with one another, in the case of preferred embodiments of the inventive puzzle, at least one projection protruding from the edge of the recess or from the edge of the extension is in discontinuous contact with the opposite edge of the extension or recess. By the term "in discontinuous contact" it is meant here that the protrusion protruding from the edge of the recess or extension does not contact the respective opposite edge along the entire edge of the connection area. In particular, the protrusion according to the invention should therefore not be a rib extending along the entire connecting region. Preferably, the discontinuous contact is an approximately punctiform contact, i. the protruding projection is designed so that it touches the opposite edge in the connection area only approximately punctiform, but a short line-shaped contact is also possible.
Pro Verbindungsbereich können mehrere herausragende Vorsprünge vorgesehen sein. Wenn die Ausnehmung wie bei herkömmlichen Puzzlespielen weithin üblich eine hinterschnittene Ausnehmung ist, dann ist in dem Verbindungsbereich vorzugsweise jeweils ein Vorsprung auf beiden Seiten des Beginns der Hinterschneidung vorhanden, d.h. in dem Bereich, in dem die Ausnehmung sich in das Puzzleteil hinein erweitert. Durch eine solche Anordnung von Vorsprüngen werden zwei aneinandergrenzende Puzzleteile zueinander gezogen, was die exakte Passung im Bereich ihrer außerhalb des Verbindungsbereichs liegenden Ränder noch verbessert und die gegenseitige Abstützung der Puzzleteile untereinander verstärkt. Die Vorsprünge können sich vom Rand der Ausnehmung oder vom Rand des Fortsatzes erstrecken, es kann sich ebenso gut aber ein Vorsprung vom Rand der Ausnehmung und der zweite Vorsprung vom Rand des Fortsatzes erstrecken. Auch sind mehr als zwei Vorsprünge im Verbindungsbereich möglich.For each connection area, a plurality of protruding projections may be provided. If, as in conventional puzzles, the recess is usually an undercut recess, then there is preferably in each case a projection on both sides of the beginning of the undercut in the connection region, ie in the region in which the recess widens into the puzzle piece. By such an arrangement of projections, two adjoining puzzle pieces are pulled towards each other, which further improves the exact fit in the region of their edges lying outside the connection region and the mutual Supporting the puzzle pieces reinforced with each other. The projections may extend from the edge of the recess or from the edge of the extension, but it may just as well extend a projection from the edge of the recess and the second projection from the edge of the extension. Also, more than two projections in the connection area are possible.
Vorzugsweise erstreckt sich der oder jeder Vorsprung nicht bis zur Oberseite und/oder nicht bis zur Unterseite des Fortsatzes oder der Ausnehmung. Auf diese Weise sind die Vorsprünge von der Oberseite und/oder der Unterseite im zusammengesetzten Zustand der Puzzleteile mit bloßem Auge nicht zu erkennen.Preferably, the or each projection does not extend to the top and / or not to the bottom of the extension or recess. In this way, the protrusions from the top and / or the bottom in the assembled state of the puzzle pieces are not visible to the naked eye.
Obwohl nicht unbedingt notwendig kann jedem Vorsprung eine korrespondierende Vertiefung im gegenüberliegenden Rand des Fortsatzes bzw. der Ausnehmung zugeordnet sein. Ohne die korrespondierende Vertiefung bewirkt jeder Vorsprung eine vorzugsweise punktförmige Klemmung zwischen Fortsatz und Ausnehmung im Verbindungsbereich. Mit korrespondierender Vertiefung tritt dieser Klemmeffekt ebenfalls auf, wird jedoch durch ein beim Zusammensetzen der Puzzleteile fühlbares Einrasten oder Einklicken der Teile ineinander ergänzt, wodurch die haptische Qualität des Puzzlevorgangs erhöht wird. Ein Spieler erhält dadurch das Gefühl exakt und mit definiertem Kraftaufwand ineinander einrastender Puzzleteile.Although not absolutely necessary, each projection may be associated with a corresponding recess in the opposite edge of the extension or the recess. Without the corresponding recess each projection causes a preferably punctiform clamping between extension and recess in the connection area. With a corresponding depression this clamping effect also occurs, but is complemented by a palpable when assembling the puzzle pieces engagement or clicking the parts into each other, whereby the haptic quality of the puzzle process is increased. A player thus receives the feeling exactly and with defined force in each other latching puzzle pieces.
Die erfindungsgemäß bei bevorzugten Ausführungsformen vorgesehenen Vorsprünge im Verbindungsbereich erlauben eine Aufgabentrennung der unterschiedlichen Randbereiche eines Puzzleteils: Der Rand des Puzzleteilhauptkörpers kann auf Passgenauigkeit optimiert werden und muss nicht für eine Klemmung sorgen, während der Verbindungsbereich in Richtung einer einfachen Zusammensetzbarkeit von oben nach unten bei gleichzeitiger Bereitstellung vorzugsweise punktförmiger Klemmwirkungen optimierbar ist. Die erfindungsgemäßen Vorsprünge können lediglich in kritischen Bereichen des Puzzlespiels oder überall vorgesehen sein. In letzterem Fall bildet die Gesamtheit aller Vorsprünge vorzugsweise ein die Mantelfläche des Hohlkörpers überspannendes Kontaktstellennetz, welches den zusammengesetzten Hohlkörper zusätzlich stabilisiert.The protrusions in the connection region provided according to the invention in preferred embodiments allow a separation of the different edge regions of a puzzle piece: the edge of the puzzle piece main body can be optimized for accuracy of fit and need not provide clamping, while the connecting region is in the direction of simple top-to-bottom composability while providing preferably punctiform clamping effects can be optimized. The projections according to the invention can be provided only in critical areas of the puzzle or anywhere. In the latter case, the entirety of all protrusions preferably forms a contact point network spanning the lateral surface of the hollow body, which additionally stabilizes the assembled hollow body.
Die Kante zwischen der Oberseite des oder jedes Fortsatzes und seinem Rand und/oder die Kante zwischen der Unterseite des oder jedes Fortsatzes und seinem Rand kann mehr oder weniger abgerundet ausgeführt sein. Auf diese Weise werden scharfe Kanten vermieden und es wird, insbesondere auf der Außenseite des Hohlkorpers, für das typische Erscheinungsbild eines Puzzlespiels gesorgt. Analog kann die Kante zwischen der Oberseite der oder jeder Ausnehmung und ihrem Rand und/oder die Kante zwischen der Unterseite der oder jeder Ausnehmung und ihrem Rand mehr oder weniger abgerundet ausgeführt sein.The edge between the top of the or each extension and its edge and / or the edge between the bottom of the or each extension and its edge may be made more or less rounded. In this way, sharp edges are avoided and it is, especially on the outside of the hollow body, provided for the typical appearance of a puzzle. Similarly, the edge between the top of the or each recess and its edge and / or the edge between the bottom of the or each recess and its edge may be made more or less rounded.
Schließlich können auch die Kanten zwischen der Oberseite jedes Puzzleteils und seinem Rand und/oder die Kanten zwischen der Unterseite jedes Puzzleteils und seinem Rand mehr oder weniger abgerundet ausgeführt sein. Auch lassen sich nicht abgerundete Kanten insbesondere auf der Oberseite des Puzzleteils kombinieren mit abgerundet ausgeführten Kanten der Fortsätze und/oder Ausnehmungen. Eine solche Ausgestaltung führt zu einer qualitativ sehr hochwertigen weil nahezu geschlossenen Hohlkörperoberfläche bei dennoch puzzletypischem Aussehen.Finally, the edges between the top of each puzzle piece and its edge and / or the edges between the bottom of each puzzle piece and its edge may be made more or less rounded. It is also possible to combine not rounded edges, in particular on the upper side of the puzzle piece, with rounded edges of the extensions and / or recesses. Such a design leads to a very high-quality because almost closed hollow body surface yet puzzletypischem appearance.
Für alle genannten Ausführungsformen des erfindungsgemäßen Puzzlespiels lassen sich die einzelnen Puzzleteile vorteilhaft aus Kunststoff im Spritzgussverfahren herstellen.For all mentioned embodiments of the puzzle game according to the invention, the individual puzzle pieces can advantageously be produced from plastic by injection molding.

Sowohl die Ausnehmung 20 als auch der Fortsatz 22 sind im gezeigten Beispiel hinterschnitten ausgeführt, jedoch ist eine solche hinterschnittene Ausbildung nicht zwangsnotwendig. Jeder Ausnehmung 20 und jedem Fortsatz 22 entspricht in einem angrenzenden Puzzleteil ein korrespondierend ausgebildeter Fortsatz bzw. eine korrespondierend ausgebildete Ausnehmung, so dass zwei aneinander angrenzende Puzzleteile 10 durch Ineinanderfügen der Verbindungsbereiche 18 miteinander verbunden werden können. Es versteht sich, dass an einem Puzzleteil 10 mehrere Ausnehmungen 20 und/oder Fortsätze 22 vorhanden sein können und dass ihre Gestalt jeweils unterschiedlich sein kann.Both the
Eine Vielzahl von Puzzleteilen 10, deren Aussehen sich natürlich voneinander unterscheiden kann, ergibt im zusammengesetzten Zustand einen Hohlkörper wie beispielsweise einen Würfel, eine Kugel, eine Pyramide, einen Oktaeder, einen Quader, ein Herz, einen Bären oder ein anderes Tier oder auch ein Gebäude. Damit ein solcher Hohlkörper im zusammengesetzten Zustand ausreichend stabil ist und die einzelnen Puzzleteile 10 sich einfach und dennoch exakt zusammensetzen lassen, ist bei jeweils zwei aneinandergrenzenden Puzzleteilen 10 der Verlauf ihrer einander zugewandten Ränder 16 zwischen der Oberseite 12 und der Unterseite 14 festgelegt durch eine Winkelhalbierende λ eines Flächenwinkels γ, der zwischen zwei Geraden α und β gebildet ist (siehe die

Mittels der zuvor dargelegten Gestaltungsvorschrift lassen sich die Ränder 16 nahezu beliebig geformter Puzzleteile 10 so festlegen, dass immer eine exakte und sich gut aneinander abstützende Passung zwischen den Puzzleteilen gewährleistet ist. In manchen Fällen, etwa bei einem kugelförmigen Puzzle, ist es vorteilhaft, die mit der zuvor erläuterten Konstruktionsvorschrift erhaltene Gestalt der einander zugewandten Ränder 16 so zu modifizieren, dass diese Ränder in Dickenrichtung der Puzzleteile 10 nicht parallel zueinander verlaufen, sondern sich von der Puzzleteiloberseite 12 zur Puzzleteilunterseite 14 voneinander entfernen. Auf diese Weise können die einander zugewandten Ränder 16 der einzelnen Puzzleteile 10 an ihrer Oberseite 12 nahezu spaltfrei zusammengefügt werden, während sich zwischen je zwei Puzzleteilen 10 ein nach innen hin zunehmender Spalt ergibt. Vorzugsweise beträgt die Abweichung von der Randparallelität insgesamt wenigstens fünf Grad, d.h. bei jedem Puzzleteil 10 weicht der Randverlauf des einem anderen Puzzleteil 10 zugewandten Randes um mindestens 2,5 Grad in der beschriebenen Weise von einem parallelen Verlauf ab. Hingewiesen sei hier darauf, dass der Rand 16 nur der Rand des Puzzleteilhauptkörpers ist, dass die zuvor angegebenen Gestaltungsvorschriften also nicht für den sich in den Verbindungsbereichen 18 befindenden Rand gelten.By means of the design rule set out above, the
