Description

Technical Field

[0001] The invention relates to the field of marble tracks consisting of individual building blocks, i.e., flexibly constructible marble tracks, in which a marble groove is formed by a plurality of different building blocks, which are positioned relative to one another in such a way that they together form this marble groove, along which marbles or other rolling elements can then roll. Background Art

[0002] Such a marble track is known from EP 2 384 797 B1. A marble track system is also known under the brand name "Hubelino", which is related to the marble track subject of the present invention.

[0003] This marble track and the marble track according to the invention can be assembled in a manner known, for example, from the toy systems LEGO and DUPLO. For this purpose, the building blocks have coupling bosses on the upper side and / or coupling holes on the lower side, which are arranged in a horizontal two-dimensional grid with constant basic dimensions in the longitudinal and transverse directions. The coupling holes are designed here for clamping the coupling bosses in a force-fitting manner. The known systems and preferably also the system according to the invention also have a uniform standard height dimension in addition to the uniform horizontal basic dimensions.

[0004] The systems known to date can be improved with regard to the stability of the system, the flexibility of possible configurations and the interest. Summary of the invention

[0005] The object of the present invention is to reduce the disadvantages of the prior art.

[0006] The object underlying the invention is firstly achieved by a grooved building block for a marble track, which is designed to be coupled to other building blocks of a corresponding design of the marble track. For this purpose, the grooved building block has a plurality of upwardly directed coupling lugs and downwardly directed coupling holes, which are arranged in a horizontal two-dimensional grid with the same basic dimensions in the longitudinal and transverse directions, wherein the coupling holes are designed to accommodate coupling lugs of the same type as the coupling lugs of the grooved building block in a force-fitting, clamping manner.

[0007] The groove building block has a ball groove with a first groove end and a second groove end, wherein a coupling section is provided at one or preferably both groove ends laterally offset from the ball groove, and the coupling sections are respectively equipped with at least one coupling protrusion and / or at least one coupling hole.

[0008] The slot building block has a middle section between the end coupling sections, which middle section has no coupling projections and no coupling holes.

[0009] Thus, it is stipulated in the slot-type building block according to the present invention that such a slot-type building block has coupling sections on at least one side of the slot at one end or both ends of the marble slot, and the coupling sections can be fixed to the underlying building block of the marble track by means of coupling holes and / or allow the installation of the building blocks to be inserted onto the slot-type building block by means of at least one coupling lug. When the one or more coupling sections at the lower side have coupling holes offset laterally from the marble slot, particularly good retention at the underlying building block can be achieved. This shows that the stability is significantly higher than when such coupling holes are provided only below the marble slot.

[0010] When the one or more coupling sections at the upper side have coupling lugs offset laterally from the marble slot, then these coupling lugs can be used as fixing devices for the structures arranged above the slot-type building block. Such fixing devices can also be realized by additional building blocks other than the slot-type building block. However, the structural stability is significantly improved by integrating them into the slot-type building block.

[0011] In addition, both the coupling holes at the lower side of the coupling section and the coupling lugs at the upper side of the coupling section are suitable for connecting the slot-type building blocks that are abutted against each other at the end sides. Thus, a high degree of stability can be achieved, and the high degree of stability avoids the undesired deviation and interference of the marble rolling between the building blocks. In particular, the connection can be created by means of an arc portion mounted on the coupling lugs of two slot-type building blocks. This coupling possibility of the slot-type building block according to the present invention particularly also allows a plurality of slot-type building blocks to be connected into a common stable bridge.

[0012] The coupling section can have a height of a standard height dimension, which is preferably also the height of the marble slot and the slot-type building block as a whole. However, a particularly preferred structural solution is one in which the coupling section has a smaller height, in particular one-third to two-thirds of the standard height dimension. This allows a plurality of slot-type building blocks to be connected to each other by other inserted building blocks that do not protrude in the height direction beyond the marble slot and the slot-type building block as a whole.

[0013] It is also possible to have a construction scheme in which at least one coupling section of the slot-type building block that is laterally offset from the marble groove and preferably all the coupling sections of the slot-type building block are constructed such that the coupling sections are arranged at a distance from the deepest plane of the slot-type building block in the vertical direction. This can be achieved in particular by a coupling section whose height (without coupling granules) is only one-third of the standard height dimension and is spaced from the upper side of the slot-type building block (without taking into account the coupling granules there) and from the lower side of the slot-type building block by one-third of the standard height dimension respectively. The advantage of this construction scheme is that coupling building blocks can be placed above and / or below the flatter coupling section in order to establish a coupling connection with an adjacent slot-type building block, without thereby causing the total height of the slot-type building block together with this coupling building block to exceed the height of a single slot-type building block.

[0014] The marble groove extends between at least two groove ends, wherein, according to the invention, the marble groove extends through the middle part, in the region of which no coupling holes and in particular no coupling granules are provided. This middle part has a length of at least a single basic dimension, preferably at least twice the basic dimension and particularly preferably at least four times the basic dimension with reference to the center line of the marble groove.

[0015] The middle part can seemingly consist only of the marble groove itself due to the absence of granules provided laterally to the marble groove. The slot-type building block can in particular at least partly have a cross-section transverse to the extension direction of the marble groove in this middle part, which cross-section is formed only by a groove cross-section with a substantially uniform material thickness, wherein the groove cross-section is preferably circular-arc-shaped or semi-shell-shaped.

[0016] A groove cross-section with a substantially uniform material thickness is also understood when the material thickness varies by no more than 30% or when the material thickness is uniformly less than 2 mm here.

[0017] The middle part gives the building block a high degree of lightness in terms of aesthetics, and this is also functionally important. Since it is desirable in the marble track to be able to visually trace the route of the marble as completely as possible, a finer middle part is advantageous because one can see the plane below the marble track when passing through the middle part.

[0018] The slot-type building block according to the invention preferably has coupling sections on both sides of the marble groove at at least one groove end, preferably at two groove ends, and the coupling sections are provided with at least one coupling granule and / or at least one coupling hole. The slot-type building block can in particular be constructed symmetrically and have one or two mirror-symmetrically constructed coupling sections at each of the two ends of the marble groove. The symmetrical construction facilitates children to build this marble track.

[0019] The coupling sections on both sides of the marble groove are preferably interconnected at the lower side by a connecting section and equipped with coupling holes in such a way that they allow both a coupling offset laterally from the marble groove and a coupling below the marble groove.

[0020] Such coupling sections on both sides of the marble groove and connected at the lower side increase the stability again, because the fixing of the grooved building block on the underlying structure can be done in the area of more studs of the underlying structure. In addition, the building block also gains a higher internal stability, because it is less likely to remove the coupling section from the original groove section that defines the boundary of the marble groove.

[0021] Particularly preferably, the coupling section at the upper side of the grooved building block is provided with exactly one coupling stud, wherein preferably at the two groove ends, one coupling section each with exactly one coupling stud is provided on both sides of the marble groove.

[0022] Although it is advantageous to provide two coupling studs on each side of the marble groove at the upper side. However, in the common construction method, the grooved building blocks according to the invention are mounted against each other at the ends, so that they provide two juxtaposed coupling studs through one coupling section each with one coupling stud to build other building blocks and to stably connect two grooved building blocks.

[0023] But it is also possible that at least one coupling section is provided with at least two coupling studs. Thus, for example, two coupling studs each can be provided along the extension direction and / or transversely to the extension direction, so that a 1 x2, 2 x 1 or 2 x 2 arrangement of coupling studs is provided at the upper side of the coupling section for building other building blocks.

[0024] The grooved building block can be configured as a straight track building block, so that it has a straight extension length when projected onto a horizontal plane. If such a grooved building block has coupling sections on both sides at the two ends of the marble groove, then overall a bone shape of the building block is produced.

[0025] The marble groove of such a straight track building block can have a uniform level. Alternatively, the marble groove can have a level that varies from one groove end to the other, especially a continuously descending or ascending level. Continuously is understood here as meaning that the building block does not have uphill and downhill sections, but either only has uphill sections and optionally flat sections, or only has downhill sections and optionally flat sections. However, a straight track building block is also possible, which has a descending and ascending level singly or repeatedly along the extension direction of the marble groove. Thus, for example, a hill or valley can be provided, which slows down the marbles during passage and then accelerates them again, or first accelerates them and then slows them down again.

[0026] The trough-shaped building blocks can be configured into curved building blocks, wherein the curved building blocks have an extension portion that is bent by 90° with reference to the horizontal plane.

[0027] Also like the straight building blocks described above, such curved building blocks have a uniform level or a level that varies from one trough end to the other trough end, in particular a continuously decreasing level or a level that decreases and increases singly or repeatedly along the extension direction of the marble trough.

[0028] In the curved building blocks, it is also possible that the marble trough is designed as a steeply curved trough with an outer trough wall that extends beyond the inner trough wall. The trough bottom can have a uniform level or a level that is slightly raised in the middle part. In the curved building blocks with a downhill slope, the steeply curved structure is particularly likely to be advantageous.

[0029] In a particular configuration of the trough-shaped building blocks according to the invention, it can be provided that the intermediate part without coupling studs and coupling holes is configured as a flexible intermediate part, which allows plastic and / or elastic deformation without damage, and through which the coupling sections at the two trough ends can be positioned in at least two possible relative positions, and the relative positions deviate from each other by at least a single basic dimension in the longitudinal or transverse direction. Thus, it is also possible to arrange them in relative positions that are offset from each other by at least one standard height dimension in the vertical direction.

[0030] The flexible intermediate part can obtain the required flexibility through material selection, but especially through alternating cuts on both sides and preferably in the intermediate part. Thus, it is possible to use such trough-shaped building blocks at least to a limited extent flexibly, that is, the coupling sections at the two ends can be fixed to the underlying structure in different relative positions in the height direction or in the transverse direction. When the flexibility is sufficient, the trough-shaped building blocks can be selectively used as straight building blocks or curved building blocks.

[0031] A particular configuration of the trough-shaped building blocks according to the invention provides that at least one of the coupling sections in the area of the trough ends has a coupling overhang structure (Kopplungsüberhang) that extends beyond the trough end along the extension direction and has at least one coupling stud and / or at least one coupling hole.

[0032] This coupling overhang structure thus extends beyond the end of the marble trough at the corresponding end. It allows direct coupling to the next trough-shaped building block at the coupling sections of adjacent trough-shaped building blocks through at least one coupling stud and coupling hole, so that a separate coupling building block is not required.

[0033] Particularly advantageous in this context is that at least one second coupling section of the groove building block has a shape, particularly with a cutout, in the region of the same or opposite groove ends, which cutout is suitable for coupling such a coupling spanning structure, so that the coupling spanning structure can be coupled at this second coupling section when the marble grooves are flush-connected.

[0034] A first variant can be considered here, in which two coupling sections at the same groove end have a coupling spanning structure, and in which two coupling sections at the other groove end have a shape or cutout provided for their accommodation. Conversely, in a second variant, the two coupling sections at the same groove end are constructed conversely, which results in that two coupled groove building blocks engage with each other from below and support each other in the coupling region. This increases the stability of the coupling.

[0035] Also possible is such a configuration of a groove building block according to the invention with coupling sections, in which the coupling sections have a coupling spanning structure in the region of the two groove ends. These coupling spanning structures of the two contact sections have at least one coupling granule and / or at least one coupling hole.

[0036] Such a groove building block with coupling spanning structures on both sides can be particularly advantageously used as a final element in a gap defined by other groove building blocks. The coupling spanning structures on both sides particularly preferably have downwardly directed coupling holes. Particularly preferably, two coupling spanning structures are provided on both sides of the marble groove at the two groove ends. Corresponding to such a groove building block with coupling spanning structures on both sides at the two ends of the groove, it is also possible to provide within the scope of a building block set such a groove building block which does not have coupling spanning structures at the two groove ends, but has a shaped coupling section which allows the groove building block with coupling spanning structures on both sides to be directly coupled when a common groove is formed.

[0037] Furthermore and particularly as an alternative to the groove building block described above, the invention also relates to a groove building block for a marble track, which is constructed for coupling to a correspondingly designed further building block of the marble track, wherein the groove building block has for this purpose a plurality of upwardly directed coupling granules and downwardly directed coupling holes, which coupling granules and coupling holes follow a horizontal two-dimensional grid arrangement with the same basic dimensions in the longitudinal and transverse directions, and wherein the coupling holes are constructed for form-fittingly clamping and accommodating coupling granules of the same type as the coupling granules of the groove building block.

[0038] This type of grooved building block correspondingly has a marble groove with a first groove end and a second groove end corresponding to the above-mentioned grooved building block. Here, a coupling area with a coupling protrusion is particularly provided at the first groove end. The coupling protrusion extends beyond the end of the marble groove in alignment with the marble groove with reference to the horizontal plane and is arranged vertically below the marble groove. The coupling protrusion has at least one coupling granule for coupling another grooved building block.

[0039] Correspondingly, this grooved building block has another coupling area with a coupling hole below the marble groove at the second groove end. The coupling holes are arranged such that they can be coupled to the coupling granules of the coupling protrusion of a structurally identical grooved building block when the corresponding marble grooves are flush-connected.

[0040] This construction method provides building blocks that can be constructed extremely narrowly on the one hand, because in addition to the marble groove, the building blocks do not necessarily have the above-mentioned coupling sections, but the building blocks can still be directly coupled to each other. Thus, the marble groove can be quickly built, and excessive deviation between the marble grooves of adjacent grooved building blocks is avoided through the direct coupling of the grooved building blocks.

[0041] Although this construction method can also be used in principle for grooved building blocks that continuously have coupling granules or coupling holes from one groove end to the opposite groove end, it is advantageous that such grooved building blocks also have an intermediate part between the coupling areas on the end sides in the above-mentioned manner. This intermediate part has no coupling granules and preferably no coupling holes. As explained above, the length of this intermediate part is preferably at least corresponding to a single basic dimension and particularly preferably corresponding to multiple basic dimensions.

[0042] In such a grooved building block with the intermediate part having no coupling granules and preferably no coupling holes, it is particularly advantageous to construct the coupling area such that when connecting structurally identical building blocks, a common coupling area is formed. The common coupling area has two downward-pointing coupling holes successively along the extension direction of the marble groove. Preferably, the common coupling area also has two coupling holes side by side transversely to the extension direction of the marble groove and thus has a total of four coupling holes.

[0043] The common coupling area with preferably exactly 2 x 2 coupling holes is considered particularly advantageous because columns composed of very common building blocks with 2 x 2 coupling holes on the upper side can be used in an aesthetically particularly beautiful way to support this coupling area.

[0044] All the coupling holes of the common coupling area are particularly preferably formed by only one of the grooved building blocks.

[0045] The object to be solved by the present invention is also solved by a building block set for a marble track, wherein the building block set has a lower and an upper groove building block. The groove building block is constructed for coupling to another building block of a corresponding design of the marble track, wherein the lower groove building block has a plurality of upwardly directed coupling protrusions and downwardly directed coupling holes for this purpose, and wherein the lower groove building block has a plurality of downwardly directed coupling holes for this purpose, wherein the coupling holes and the coupling protrusions also follow a horizontal two-dimensional grid arrangement with the same basic dimensions in the longitudinal and transverse directions, and wherein the coupling holes are constructed for force-fittingly clamping and accommodating coupling protrusions of the same type as the coupling protrusions of the lower groove building block.

[0046] The lower slot-type building block has a marble groove that is open upward, and the upper slot-type building block has a marble groove that is open downward.

[0047] The coupling protrusions on the lower slot building block and the coupling holes on the upper slot building block are arranged relative to the corresponding ball grooves of the slot building blocks so that they allow a non-positive coupling of the slot building blocks, through which the ball grooves are at least partially oriented in the same direction and form a circumferentially closed tubular structure.

[0048] The building block set is therefore suitable for forming a tube from two parts, the lower part of which is formed by the lower slot building block and the upper part of which is formed by the upper slot building block, each of which has a marble groove. The slot building blocks can be connected by coupling protrusions at the lower slot building block and coupling holes at the upper slot building block in such a way that a circumferentially closed tube structure is formed. Such a tube structure is particularly useful at the location of the marble groove where the marbles become particularly fast and could otherwise be thrown out of the track.

[0049] The closed tube structure preferably has a substantially circular clear cross section, wherein the clear cross section is particularly preferably formed by substantially equal portions of the lower channel building block and the upper channel building block.

[0050] The groove block below is preferably configured with a coupling section at the end side corresponding to the groove block explained above. The groove block above is preferably configured with the coupling hole pointing in the direction of the groove opening and the coupling protrusion pointing in the opposite direction corresponding to the groove block below and optionally configured with the optional features described there.

[0051] The coupling studs and coupling holes can be arranged at the trough-shaped building blocks in such a way that the ball trough forms a tube structure which is shorter than the ball trough or at least the longer of the ball troughs. However, it is advantageous if the lower trough-shaped building block and the upper trough-shaped building block have ball troughs with the same extension direction and length and the coupling studs and coupling holes are arranged in such a way that a circumferentially closed tube structure with this extension direction and length is created by coupling the trough-shaped building blocks.

[0052] The circumferentially closed tube structure preferably has a length of at least four times the basic dimension.

[0053] In a particular design, the two trough-shaped building blocks have a level that varies from one trough end to the other, in particular a continuously rising or falling level or a single or repeated descending and ascending level along the extension direction of the ball trough. Forming the tube structure is particularly advantageous under this level difference, since here the risk of the balls being thrown out is particularly high.

[0054] The object to be solved by the present invention is also solved by a set of building blocks for a ball track, which set of building blocks has trough-shaped building blocks and snap-in building blocks, wherein the trough-shaped building blocks and the snap-in building blocks are configured for coupling to other correspondingly designed building blocks of the ball track, wherein the trough-shaped building blocks have a plurality of upwardly pointing coupling studs and downwardly pointing coupling holes for this purpose, and the snap-in building blocks have a plurality of downwardly pointing coupling holes for this purpose, wherein the coupling holes and the coupling studs also respectively follow a horizontal two-dimensional grid arrangement with the same basic dimension in the longitudinal and transverse directions, and wherein the coupling holes are configured for form-fittingly clamping and accommodating coupling studs of the same type as the coupling studs of the trough-shaped building blocks.

[0055] The trough-shaped building block has a ball trough with a first trough end and a second trough end. The trough-shaped building block also has at least one coupling section horizontally offset next to the ball trough, at which coupling section at least one coupling stud is provided.

[0056] The snap-in building block can be form-fittingly coupled at the coupling section of the trough-shaped building block by means of its coupling holes.

[0057] In a variant, the snap-in building block also has a rigid snap-in section which is arranged at a fixed position relative to its coupling holes and projects into the ball trough when connected to the trough-shaped building block, and thus influences the movement of the balls in the ball trough by means of the rigid snap-in section.

[0058] The snap-in building block is thus shaped in such a way that it can be fixed at the coupling studs of the trough-shaped building block with at least one coupling hole at the same time and the snap-in section extends downward via the ball trough wall into the ball trough in order to influence the movement of the balls there.

[0059] The snap-together building block alternatively has a bearing section in which a snap-in element also belonging to this building block set is movably supported, wherein this snap-in element is movably supported in such a way that it influences the movement of the marbles in the marble groove by protruding into or out of the marble groove.

[0060] In this case, the snap-together building block is shaped in such a way that it allows for the movable support of a preferably integral snap-in element, by means of which the snap-in element can move between different positions, and thus the movement of the marbles is influenced by the snap-in element and / or the marbles move the snap-in element.

[0061] The bearing section can in particular be formed by a preferably cylindrical hole in which a shaft projection of the snap-in element is supported, or by a cylindrical section that extends into a hole of the snap-in element.

[0062] The groove building block is preferably constructed with end-side coupling sections corresponding to the groove building block explained above. Such end-side coupling sections can serve as mounting sites for the snap-together building blocks. When coupling sections with coupling studs are provided on both sides of the marble groove, it may be advantageous to fasten the snap-together building blocks on both sides in order to thereby increase the stability of the installation. For this purpose, the snap-together building block preferably has coupling holes on both sides of the snap-in section or the bearing section, which can be coupled to the coupling studs of the groove building block on both sides of the marble groove.

[0063] In the case of a snap-together building block with a movable snap-in element, it may also be appropriate to provide two snap-together building blocks, each of which provides a bearing section for a common snap-in element, and thus provides a bearing section on each side of the marble groove for the movable mounting of the snap-in element.

[0064] Next, different specific snap-together building blocks are proposed:

[0065] The snap-together building block can be configured as a jump block and as such a jump block has a jump surface at the snap-in section, which rises in the extension direction of the marble groove when the snap-together building block is coupled to the groove building block. The snap-in section of such a snap-together building block thus forms a rolling surface for the marbles, by means of which the marbles are lifted from the marble groove and fly freely for a specified distance.

[0066] Such a jump block can be particularly advantageously combined with a groove building block having a downhill section, so that the marbles also experience an acceleration before the jump element.

[0067] The trough-shaped building blocks can also be configured as turnout building blocks, wherein the ball trough extends between a first trough end and a second trough end and between at least one third trough end. The ball can thus be selectively deflected from one trough end to one of the other two trough ends.

[0068] The interlocking building block for installation at the turnout building block forms an adjustment building block, wherein the bearing section preferably extends vertically at the adjustment building block and thus allows a horizontal pivoting movement of the movable interlocking element. This interlocking element serves as a deflecting part and, when the interlocking building block is coupled to the trough-shaped building block with the installed interlocking element, projects into or extends beyond the ball trough, thus causing the ball from the first trough end to move in the direction of the second or third trough end according to its position.

[0069] The trough-shaped building blocks can also be used in the reverse way, so that the balls always roll towards the third trough end from the two trough ends. In this case, the interlocking building block can be dispensed with.

[0070] In another configuration, the interlocking building block can also be configured as a bearing building block for supporting a rotor forming the interlocking element. The bearing building block projects into the ball trough in such a way when the interlocking building block is coupled to the trough-shaped building block that the bearing building block can be continuously rotated in the same direction by the balls running through the ball trough in the same direction.

[0071] Such a rotor can be used for purely aesthetic purposes. However, it is also possible to use the rotor functionally in such a way that, for example, the balls rolling along the ball trough move the rotor in such a way that the rotor releases the balls at other locations for further rolling.

[0072] Furthermore, the invention also relates to a building block set having at least two trough-shaped building blocks, which have coupling sections with coupling overhang structures by means of which the trough-shaped building blocks can be directly coupled to each other, so that their ball troughs are flush with each other. These trough-shaped building blocks preferably correspond to the trough-shaped building blocks with coupling overhang structures described above.

[0073] Furthermore, the invention also relates to the following type of building block set: The building block set has at least one first trough-shaped building block and at least one second trough-shaped building block, each of which has a ball trough with a first trough end and a second trough end. The trough-shaped building blocks are configured for coupling to each other, wherein the first trough-shaped building block has a plurality of coupling studs pointing upwards for this purpose, and wherein the second trough-shaped building block has a plurality of coupling holes pointing downwards. Here, the coupling holes and the coupling studs respectively follow a horizontal two-dimensional grid arrangement with the same basic dimensions in the longitudinal and transverse directions. The coupling holes at the second trough-shaped building block are configured for force-fittingly clamping and accommodating the coupling studs of the first trough-shaped building block.

[0074] The first grooved building block of this building block set has at each of the two ends of the groove a coupling area with coupling protrusions, the coupling protrusions extending through the respective ends of the marble groove aligned with the marble groove with reference to a horizontal plane and being arranged vertically below the marble groove, wherein the coupling protrusions each have at least one coupling granule for coupling one additional grooved building block on each side. The second grooved building block has at each of the two ends of the groove a coupling area with coupling holes pointing downward below the marble groove, the coupling holes being arranged such that they can be coupled to the coupling granules of the coupling protrusions of the first grooved building block when the respective marble grooves are flush-connected.

[0075] Thus, the two grooved building blocks of such a grooved building block set can be directly coupled to each other in the following manner through correspondingly designed coupling areas, that is, by pressing the protruding coupling granules in the coupling area of the first grooved building block into the coupling holes in the coupling area of the second grooved building block. However, by arranging the respective coupling holes or coupling granules below or aligned with the marble groove, a very narrow construction can be achieved.

[0076] A longer marble groove, which should consist of more than just two grooved building blocks, can be formed by attaching additional building blocks corresponding to the first or second grooved building block to the respective ends in an alternating arrangement.

[0077] Also applicable to the grooved building blocks of this building block set is that these grooved building blocks preferably have, in the manner already described above, an intermediate part between the coupling areas on the end sides, which intermediate part has no coupling granules and preferably no coupling holes.

[0078] As already explained at the beginning of this text, the building blocks to be used according to the invention are designed in the type of LEGO building blocks or DUPLO building blocks, which involves the use of coupling granules and coupling holes and their clamping fit effect.

[0079] The building blocks are furthermore preferably directly compatible with one of these systems, so that the underlying structure can be built from the building blocks of these or similar systems. For compatibility with the LEGO system, the basic dimension is 8 mm, and for compatibility with the DUPLO system, the basic dimension is 16 mm. The coupling granules preferably have a cylindrical basic shape, with an outer diameter of 4.8 mm for compatibility with LEGO and an outer diameter of 9.6 mm for compatibility with DUOLO.

[0080] The maximum net width of the marble groove, transversely to the extension direction, is preferably between 1.6 and 2 times the basic dimension, so that the width of a grooved building block with two coupling sections arranged on both sides of the marble groove at the end of the groove corresponds to four times the basic dimension.

[0081] The standard height dimension preferably corresponds to either 9.6 mm or 19.2 mm for LEGO or DUOLO. The coupling sections, offset from the marble groove, preferably have this standard height dimension or one third of this standard height dimension as the height (without coupling studs).

[0082] As in the known LEGO system and DUPLO system, the building blocks are preferably made entirely or mainly of plastic, in particular of ABS, polycarbonate or polyamide.

[0083] The different building blocks according to the invention are preferably integral bodies that cannot be disassembled without damage.

[0084] The invention also relates to a marble track having a plurality of building blocks, at least some of which have marble grooves, wherein the building blocks are configured to be coupled to corresponding designed additional building blocks of the marble track, and wherein the building blocks have, for this purpose, a plurality of upwardly pointing coupling studs and / or downwardly pointing coupling holes, which coupling studs and coupling holes follow a horizontal two-dimensional grid arrangement with the same basic dimension in the longitudinal and transverse directions, and wherein the coupling holes are configured to clampingly receive the coupling studs in a force-fitting manner.

[0085] The marble track according to the invention here includes at least one building block or at least one set of building blocks of the above type.

[0116] Figure 1 The marble track 10 is shown, which is composed of a base plate 20 and a superstructure composed of a single building block mounted on the base plate. In Figure 2 In order to better understand, the superstructure 30 without the base plate 20 is shown.

[0117] Different building blocks and the base plate are connected to each other through a coupling system, which is generally known in different toy systems such as LEGO and DUPLO in particular. The building blocks have downward-pointing coupling holes or upward-pointing coupling studs. The coupling holes and the coupling studs form a convenient clamping coupling with each other and can thus be firmly joined together with little force consumption, but can also be simply separated again by the child. The coupling holes and the coupling studs are separated from each other by a basic dimension G (8 mm in the case of LEGO) or an integer multiple of G along the longitudinal and transverse directions following a basic grid. The height of most of the shown building blocks is consistent with the standard height dimension (9.6 mm in the case of LEGO).

[0118] The superstructure 30 of the marble track is assembled from a plurality of different building blocks. Among them, some involve trough-shaped building blocks 100, 110, 120, 140, 150, 240, 220 with upward-open marble troughs. Other building blocks 130, 190, 250 form covers for the marble troughs. Other building blocks 210, 230 with attachments 214, 234 or the interlocking building block 200 are arranged again in such a way that they cooperate with the marble 40 in the marble trough. A plurality of other building blocks 50, 60, 62 form a lower structure or an upper structure below or above the building blocks with marble troughs.

[0119] As has been shown with the help of Figure 2 As can be seen, most of the building blocks with upward-open or downward-open marble troughs are constructed in such a way that they have a bone-like shape. At both ends and on both sides of the marble trough respectively, coupling sections are connected to an elongated middle part formed only by the walls of the marble trough.

[0120] In particular, the coupling holes and the coupling studs are provided at the coupling sections of the generally bone-shaped trough-shaped building blocks. This allows such trough-shaped building blocks to be coupled to each other through connecting building blocks 60, 62 mounted from below or from above and thus establish a firm connection, and this connection also allows the construction of an elongated bridge in a way that can be clearly seen by Figure 2 As can be clearly seen.

[0121] Figure 1 and 2The specific marble track 10 is merely exemplary in order to illustrate the assembly of the building blocks and building block sets according to the invention. The building blocks and building block sets according to the invention are particularly advantageous in marble tracks nested in larger and higher dimensions.

[0122] The building blocks of the marble track 10 and additional building blocks that can be additionally used here are explained in detail with the aid of the following figures.

[0123] Figure 3A and 3B Fig. shows a simple groove building block 100 which has a straight marble groove 72. In the region of the ends 74A, 74B of the marble groove 72, coupling sections 70 are provided on both sides of the marble groove 72, the coupling sections each having coupling studs 80 pointing upwards and coupling holes 82 pointing downwards. These coupling sections 70 have a basic area and a height, the basic area corresponding to the square of the basic dimension G and the height corresponding to the standard height dimension H. At the lower side, the coupling sections 70 are interconnected by a connecting section 71, so that four coupling holes 82 are provided at each end here.

[0124] In the intermediate part 76 between the coupling sections and the connecting section 70, 71 at the end side in the extending direction, the building block is configured to be elongated and consists essentially only of the walls directly forming the marble groove. Thus, a convenient and clear construction method with these groove building blocks 100 is achieved.

[0125] The coupling studs 80 offset relative to the marble groove 72 at the upper side are particularly well-suited for coupling the groove building blocks to each other and furthermore provide coupling points in order to be able to build structures together with other simple building blocks, through which a higher plane on which the groove building blocks can be placed can be formed. The external coupling holes 82 arranged offset from the marble groove 72 at the lower side of the groove building block 100 allow the groove building block to be particularly firmly fixed to the base plate or other underlying structures.

[0126] Figure 4A and 4B Fig. shows another type of groove building block 110. This groove building block also forms a straight line when projected onto a horizontal plane. However, the marble groove 72 of this building block is provided with a downhill slope, so that the coupling sections 70 are offset from each other by a standard height unit H at the opposite ends of the groove building block 110. Referring to Figure 4A The marble 40 coming out from the left is thus accelerated in the marble groove 72.

[0127] Figure 5A and 5BShows an alternative slot building block 120, which is also constructed straight and flat like the slot building block 100. However, the coupling sections 70 are each provided with two coupling studs 80 here, which may be advantageous in individual cases for attaching additional elements such as the jump platforms to be explained below.

[0128] Figure 6A and 6B Shows the upper slot building block 130, which has the same length and basic shape as the slot building block 100 of Figure 3A and 3B However, the marble groove 73 is open downward here, so that the slot building block 130 has four upward-pointing coupling studs 80 at each end, but only two downward-pointing coupling holes 82, different from the slot building block 100.

[0129] This building block was initially constructed for cooperative action with a slot building block corresponding to the slot building block 100. Figure 7 Shows how the slot building blocks are joined together so that the slot building blocks form a circumferentially closed tube. This tube can be used especially where the marbles 40 would pop out particularly quickly or uncontrollably in the marble track 10 to prevent the marbles 40 from popping out.

[0130] Figure 8A and 8B Shows a special slot building block 140, which is particularly characterized in that in the middle part 76, the marble groove is provided with lateral cuts 78. This allows for flexible insertion of these slot building blocks. Thus, the coupling sections 70 can be coupled to the underlying building blocks offset from each other in a basic grid at both ends. It is also possible that, as shown in Figure 2 such a flexible slot building block is used as a bend and the coupling sections 70 are fixed to the underlying structure with a 90° rotation relative to each other.

[0131] Figure 9A and 9B Shows a slot building block rigidly designed as a 90° bend, which is also coordinated with the slot building blocks 100 of Figure 3A and 3B in terms of its coupling sections 70.

[0132] Figure 10A and 10B Shows the bend building block 160 again, where this bend building block is provided with a downhill similar to the slot building block 110. This also relates to an accelerating bend.

[0133] Figure 11A and 11BAn alternative construction is shown, in which, again, corresponding to Figure 5A and 5B two coupling studs 80 each are provided for the coupling section 70.

[0134] Figure 12A and 12B as well as 13A and 13B corresponding to Figure 6A and 6B Similarly shown are upper trough building blocks 180, 190 with a downwardly open marbles trough 73, which upper trough building blocks are duly plugged onto correspondingly shaped lower trough building blocks 150, 170 in order to jointly form a tubular trough.

[0135] Figure 14A and 14B Shown is a snap - together building block 200, which has two fixing sections 206 with coupling studs 80 and coupling holes 82. Between the fixing sections 206, a snap - together section 202 is provided, which is integrally formed with these fixing sections and which provides a jump surface 203 shaped like a ski jump.

[0136] As can be seen with the aid of Figure 15 this ski - jump building block 200 is duly mounted at a trough building block such as the trough building block 110 provided with a downhill slope, in order to snap - together into the marbles trough 72 in such a way that the marbles 40 can be lifted out of the marbles trough here and perform a jump.

[0137] Figure 16A and 16B Shown are two snap - together building blocks 210, which each have a bearing section 212 designed as a through - hole. This bearing section is used to support a snap - together element 214 in the form of a rotor by means of a shaft section 215 mounted here. The total composite structure consisting of the snap - together building blocks 210 and the snap - together element 214 in the form of a rotor can be mounted on a trough building block in the manner explained in Figure 17 so that the marbles rolling along this trough building block further rotate the rotor here.

[0138] Figure 18A and 18B Shown is a trough building block 220 in the form of a switch building block. The marbles trough 72 of this building block 220 thus not only has a first trough end 74A and a second trough end 74B, but also an alternative third trough end 74C. In addition, this switch building block 220, like the previous building blocks, has end - side coupling sections 70 on both sides or between the marbles troughs 72. In order to be able to turn at this switch building block, as the marbles coming from the trough end 74A are further guided, there are provided in Figure 19A and 19BThe snap-together building block 230 shown therein, which currently forms an adjustment building block with the vertical bearing section 232. An interlocking element 234 in the form of a steering element is provided here, which can pivot relative to the building block 230 in a restricted manner. Due to its special shape, this steering element pivots the marbles that are about to reach the switch, so that the marbles are alternately steered to the ends 74B and 74C of the groove. Other steering elements are also feasible, which are manually pivoted in order to permanently steer the marbles to one of the two groove ends 74B and 74C.

[0139] As Figure 20 shown, the composite structure consisting of the snap-together building block 230 and the interlocking element 234 mounted on this snap-together building block is inserted into the switch building block 220 between the groove ends 74B, 74C as specified, so as to generally obtain a steerable switch.

[0140] Figures 21 to 25 Additional lower groove building blocks 300, 310, 320, 330 are shown, and their particularity lies in that a part of their coupling section 70 has a coupling overhang structure 73, and the coupling overhang structure extends out of the marble groove 72 along the extension direction.

[0141] In Figure 21 the case of the groove building block 300, two coupling overhang structures 73 are provided on the same side of the groove building block 300. On the opposite side, the coupling studs 80 are mounted slightly deeper, so that the coupling overhang structures of the same coupling building block 300 can be adjacent to each other under the flush connection of the marble groove 72 based on the deeper arrangement of the coupling studs 80. Figure 25 This connection is shown.

[0142] In Figure 22 the case of the groove building block 310, coupling overhang structures 73 are provided at both ends of the marble groove 72, one at the upper end and the other at the lower end. Additionally, the coupling studs 80 are sunk at the front end and the coupling holes 82 are raised at the rear end, so that multiple such building blocks can be adjacent to each other under the flush connection of the marble groove, and the coupling with the coupling studs 80 and the coupling holes is completed at different heights. This improves the stability.

[0143] In Figure 23 the case of the groove building block 320, the coupling section is arranged corresponding to the groove building block 310, and two differently configured coupling sections 70 are provided at each groove end. Thus, the same groove building blocks 320 can be connected in such a way that they support each other from below in the coupling area.

[0144] In Figure 24In the case of the slot-type building block 330, coupling sections 70 with coupling suspension structures 73 are provided at both ends of the marble slot 72, wherein these coupling suspension structures are constructed such that the rear coupling section 70 completely covers the front coupling section 70 non-stepwise when coupling identical building blocks.

[0145] Figure 26 and 27 Fig. shows a slot-type building block 340 which, unlike the aforementioned slot-type building block, does not have coupling sections on both sides of the marble slot 72. More precisely, this slot-type building block instead has coupling regions 77A, 77B in the regions of two slot ends 74A, 74B respectively, wherein the coupling regions 77A, 77B are configured for coupling below the marble slot 72.

[0146] As can be seen with the aid of Figure 26 In the coupling region 77B, it is constructed such that it has a coupling projection 75 which is arranged vertically below the marble slot 72 and extends beyond the end of the marble slot 72. On the upper side of this coupling projection 75, coupling granules 80 are provided. Correspondingly, on the lower side, there is another coupling region 77A with a smaller height and coupling holes 82.

[0147] Figure 27 Shows how multiple identically structured slot-type building blocks 340 can be joined together. By inserting the coupling region 77A of one slot-type building block 340 onto the coupling projection 75 of another slot-type building block, a direct and stable connection of the slot-type building blocks 340 is achieved without the need for additional building blocks. Since the lateral coupling projections corresponding to the aforementioned slot-type building blocks can thus also be dispensed with, a construction method is produced in which the building block 340 forming the marble slot is hardly wider than the marble slot 72 itself.

[0148] What is achieved by the specific design of the coupling regions 77A, 77B is that the common coupling region 77C has a lower side which is formed solely by the coupling region 77B and correspondingly its lower side dimension has 2 x 2 coupling holes 82. This is regarded as advantageous because this common coupling region can be inserted flush onto a building block or a column in an aesthetically advantageous manner, said building block or column having a square or columnar circular cross-section and an upper end face with 2 x 2 coupling granules.

[0149] A similar superstructure is achieved with the building block set depicted in Figure 28 This building block set includes two differently structured slot-type building blocks 350, 360.

[0150] The two grooved building blocks 350, 360 each have a marble groove 72 corresponding to the grooved building block 340 and have two groove ends 74A, 74B. Coupling regions 77A, 77B are provided at the two groove ends, wherein, different from the grooved building block 340, the coupling regions 77A, 77B of the two building blocks are identically configured on the respective ends.

[0151] The grooved building block 350 has two identical coupling regions 77B, each of which has a coupling projection 75, and coupling granules 80 are provided on the upper side of the coupling projection. The grooved building block 360 also has two identical coupling regions 77A, each of which has a smaller height than the coupling region 77B corresponding to the coupling region 77A of the grooved building block 340 and has coupling holes 82 provided on the lower side.

[0152] Thus, the grooved building blocks 350, 360 can be successively spliced alternately as shown, Figure 29 so that a stable coupling possibility is obtained without additional coupling building blocks.

[0153] By means of Figures 30 to 32 the building blocks 370, 380, 390, special variant possibilities are illustrated.

[0154] According to Figure 30 the building block 370 is Figure 21 a modified version of the building block 300. Its particularity lies in that the coupling section 70 does not extend to the lowermost plane of the building block 370, but rather a spacing is left for this purpose. On the one hand, this allows the grooved building block 370 to be placed in an arrangement slightly sunken relative to the surrounding structure. In addition, this construction also allows, after two identical grooved building blocks 370 are coupled, the coupled coupling sections here can be strengthened with additional coupling elements in the case of heavy loads, for example, in the case of a long bridge section without support columns, and these additional coupling elements increase the total height of the structure relative to the isolated grooved building block.

[0155] According to Figure 31 the building block 380 is Figure 30 a variant of the building block 370 according to Figure 30 In this case, the coupling section 70 is identically configured at the two groove ends 74A, 74B of the groove 72 and thus corresponds to

[0156] They can in particular also be alternately combined with the building blocks 390 corresponding to Figure 32 The grooved building block 390 is likewise a grooved building block with a marble groove 72 and coupling sections 70 at the two groove ends 74A, 74B. Here, the coupling sections 70 are identically constructed at the two ends and are constructed in a coordinated manner with the front end of the building block 370 corresponding to Figure 30 .

[0157] Similar to the principle explained for the building blocks 350, 360, the building blocks 380, 390 can accordingly also be used alternately. However, a plurality of grooved building blocks 390 can also be used with one another in such a way that they are connected by complementary coupling building blocks which couple the coupling sections 70 of two successively positioned grooved building blocks 390 to one another at the lower side and / or at the upper side.
