Description

The invention relates to a toy building block set for producing planar spatially constructed models, by means of building blocks which have both dovetail-shaped recesses and dovetail-shaped projections and by means of which the building blocks are connected to one another.In the prior art, for example, in DE 23 29 339 A1, WO 0177 456 A1, US 2010 / 0282060 A1 and US 2020 / 0171400 A1, modules for the construction of buildings are arranged on their front and / or side walls as described above, as well as dovetail-shaped recesses and dovetail-shaped projections, by means of which the modules engage one another during assembly by pushing the dovetail guides one inside the other and are thus firmly connected to one another in a plane.On the upper or lower side of these modules, usually square, round or rectangular projections and / or recesses are arranged, to which projections and / or recesses assigned to the other side of the respective module, such as guide bolts, guide wires, guide webs or the like, are arranged, which fit into one another when the modules are placed on top of one another / stacked and impart stability to the overall system on account of their own weight.With the modules presented in U.S. Pat. No. 2020 / 0171400 A1, it is possible in engineering, in architecture, in filmizing or in hobby model construction to produce true-to-scale models which, if the true-to-scale model is no longer required, can be broken down again to form a collection of modules.The essential disadvantage of all the above-mentioned designs is that the assembly as well as the disassembly, i.e. the insertion of the dovetail guides into each other, requires a very high force and time expenditure in the preceding modules.DE 18 02 464 A1 discloses a further module or building block, the side surfaces of which are of planar design, and on the two end faces of which a dovetail groove is arranged in each case.The modules are connected to one another side by side by inserting a dovetail connector into the two dovetail grooves of the adjacent end faces.In addition, in this module, a dovetail groove running in the longitudinal direction is arranged on the underside and an associated dovetail web likewise extending in the longitudinal direction over the entire length of the block or block is arranged on the upper side of the latter.This solution also has the disadvantage that the assembly, i.e. the insertion of the dovetail connecting piece into the dovetail grooves of the end faces of the adjacent blocks as well as the insertion of the top or bottom into each other, in the longitudinal direction, of the dovetail webs extending over the entire length of the block or block into the associated dovetail groove of the adjacent block or block, which groove likewise extends over the entire length of the block or block, requires a very great expenditure of force and time.Also known from US 2008 / 0 280 521 A1 is a set of cubes or generally parallelepipedic bodies with interlocked dovetail formations of T-posts, half T-posts, T-slot and half T-slot and mating rails which can slidingly interlock to allow variable movement of individual cubes and placements within an array of substantially similar cubes and / or rails and which can be used as building blocks for construction boxes and for numerous other purposes, for example as storage containers. Each cube consists of six plates in two different plate types, i.e. three of each type, the T-shaped dovetail formations of which engage in one another during assembly in the form of sliding connections.In summary, it can be stated that all the above designs have in common the pushing of the dovetail webs / webs extending over the entire length and / or height of the stone or block into the associated dovetail grooves of the adjacent stone or block, which grooves likewise extend over the entire length and / or height of the stone or block, and that this pushing into one another requires a very great amount of force and time for connecting the building blocks to one another.Moreover, none of the aforementioned solutions allow stable transverse construction. Furthermore, toy building block sets are known in the prior art with which the users can practice and improve the coordination between hands and eyes.Building blocks belong to toys with the greatest diversity of types.The toy building blocks described in the prior art often have the shape of blocks of different geometrical shapes and allow stacking in different directions.Projections and recesses are arranged on / in these modules, by means of which the modules can be connected to one another by means of plug-in fits.For example, CH 692 325 A5 discloses a toy building set having planar side surfaces which are formed from blocks which can be plugged onto one another and have a top side and a bottom side and having fastening means which are arranged on the top side and on the bottom side and are formed by mutually matching ribs which are square or rectangular in cross section and are insertable into one another, the ribs of which ribs are arranged on one of the two said sides of the block and the slots are arranged on the other of the two said sides of the block.One of the most well known building blocks is LEGO® blocks, the peculiarity of which is that a single square area is used as a basic unit, which is then expanded into a rectangular body with an increased surface area.However, the structural strength achieved by the plug connection always only in one direction can be too low for the respective case of use and, with corresponding loading, lead to detachment of the plug connection, i.e. a break-down of the connection.The difficulties resulting from assembling a large structure are obvious and obvious.The object of the invention is therefore to develop a toy building block set for producing planar and spatially constructed models, by means of building blocks which have both dovetail-shaped recesses and dovetail-shaped projections and by means of which the building blocks are connected in an interlocking manner, which set does not have the aforementioned disadvantages of the prior art, and in which the novel connection of the building blocks to one another guarantees a multidimensional structural strength which, even in the event of an increased load on the connection of the building blocks, avoids a breakdown of the connection, but which, even with few components, makes it possible to assemble stable, loadable models capable of play, but also to construct large, stable, statically loadable structures (e.g. houses, towers, etc.) with a high diversity of models by a defined interaction of the individual building block types with one another, with a simple one, This is because the object of the invention is to ensure rapid, reliable, reliable mounting of the models without any additional tools, and, in addition, with very little outlay on dismantling force, simple, reliable, rapid and reliable dismantling of the models without any damage to the modules is to be ensured.According to the invention, this object is achieved by a toy building block set for producing planar and spatially constructed models, by means of which a plurality of building blocks made of plastic have the dovetail-shaped recesses as well as dovetail-shaped projections, and by means of which these building blocks are connected in an interlocking manner, according to the features of the main claim of the invention.Advantageous embodiments, details and

in thickness compared to the dovetail webs 9 adjacent to the receiving webs 13 of the side walls 11 in different graphic representations, wherein FIG. 9.3 shows the detail L from FIG. 9.2.The building blocks of the toy building block set according to the invention for the production of planar and spatially constructed models, by means of several building blocks made of plastic with dovetail-shaped recesses and dovetail-shaped projections, by means of which these building blocks can be connected in an interlocking manner, are characterized in that the basic variant of these building blocks of the toy building block set is the basic building block which has approximately the shape of a cube and which has a downwardly open square base surface, a square top wall 8, two mutually opposite square side walls 11 and two mutually opposite end walls 16, wherein both the side walls 11 and the end walls 16 have a wall thickness T.It is essential to the invention that two square dovetail webs 9 with two end faces and two longitudinal sides, which have a guide height H and a guide width B, are arranged on the square ceiling wall 8 of the base brick between the two side walls 11 opposite one another, wherein all walls arranged on the two end faces and the two longitudinal sides of the dovetail webs 9 are arranged inclined with respect to the perpendicular by the guide angle α, which lies in the range of 2° to 5°, as dovetail guide surfaces 10.It is characteristic that the end faces of the dovetail webs 9 face the side walls 11 of the base brick, and that both the end faces of the dovetail webs 9 facing the side walls 11 of the base brick and the side faces of the dovetail webs 9 facing the end walls 16 of the base brick are always spaced apart by the wall thickness T from the respectively adjacent outer edges of the base brick.It is essential that the two side surfaces running in the longitudinal direction of the dovetail webs 9 are spaced apart from one another by the web spacing W, which corresponds to 2 times the wall thickness T, and with their walls of the longitudinal sides of the dovetail webs 9, which walls are designed as dovetail guide surfaces 10, form a dovetail-shaped guide groove between the mutually adjacent dovetail webs 9.It is characteristic that stabilizing webs 12 run between the side walls 11 of the base block below the dovetail webs 9, and that the lower edges of the stabilizing webs 12 are spaced apart from the lower edge of the side walls 11 at least by the guide height H, wherein the side walls 11 below the stabilizing webs 12 form receiving webs 13 with dovetail guide surfaces 10 and the guide height H, which are spaced apart from one another by the guide width B, wherein the dovetail guide surfaces 10 are arranged inclined with respect to the perpendicular by the guide angle α, which lies in the range from 2° to 5°, and that these dovetail guide surfaces 10 arranged on the inside of the receiving webs 13 of the adjacent side walls 11 together likewise form a dovetail-shaped guide groove with a guide height H and a guide width B.It is also essential to the invention that the side surfaces arranged on the outside in the longitudinal direction of the dovetail webs 9 on two adjacent dovetail webs 9, which are designed as dovetail guide surfaces 10, together likewise form a dovetail-shaped guide having a guide height H and a guide width B.It is also important that latching grooves 14 are arranged in the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11.It is characteristic that at least one of the end walls 16 of the base brick has a recess between the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11 at least over the guide height H.When connecting the modules according to the invention, the dovetail guide surfaces 10 of the dovetail webs 9 of one module or also of a plurality of modules engage in the dovetail guide surfaces 10 of the receiving webs 13 of another module and thus form a dovetail connection.The design of the dovetail guides according to the invention enables a high-strength connection of the modules according to the invention to one another by (fitting into one another) and / or sliding, wherein the tolerances of the components are dimensioned such that they can be joined / connected to one another with a sliding fit, i.e. still displaceably by hand.Due to the flat inclined configuration and flat arrangement of the dovetail guides on the modules according to the invention, it is possible without any problem to insert and latch the dovetail-shaped projections of one module into the dovetail-shaped recesses of the adjacent module, analogous to a click connection, in order to connect the modules to one another in a quick and simple manner, in a highly fixed manner.However, by means of the solution according to the invention, it is simultaneously also possible that even after the modules have been first plugged together, they can still be displaced relative to one another along their dovetail connection for positioning purposes.For dismantling the models, the dovetail joints according to the invention between the modules are then detached from one another again simply and without damage solely by pulling apart and / or pushing apart, i.e. without any tools. According to the invention, a second structural form of the building blocks of the toy building block set, which is shown in FIGS. 8.1 to 8.6 and which is designated as a base corner brick 5, and which differs from the base brick in that one of the two end walls 16 of the base brick, apart from the wall thickness T of the side walls 11, has been removed, so that instead of one of the end walls 16 of the base brick, two receiving webs 13 spaced apart from one another by the guide width B are arranged on the base corner brick 5 with dovetail guide surfaces 10 running over a guide height H, and these dovetail guide surfaces 10 are also inclined with respect to the perpendicular by the guide angle α which lies in the range of 2° to 5°, and these dovetail guide surfaces 10 together form a dovetail-shaped guide groove having a guide height H and a guide width B, and that latching grooves 14 are arranged in the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11.It is also characteristic that a third structural form of the building blocks of the toy building block set, which is illustrated in FIGS. 5.1 to 5.5 and which is designated as base connection block 2, differs from the base corner block 5 in that the end wall 16 still remaining on the base corner block 5 is likewise replaced by two receiving webs 13 spaced apart from one another, and which together form a further dovetail-shaped guide groove with dovetail guide surfaces 10 over a guide height H and a guide width B, wherein here too latching grooves 14 are arranged in the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11.The design of the dovetail guides according to the invention also makes possible a high-strength connection of the modules according to the invention, by plugging and / or sliding, with the other modules of the module box according to the invention in these designs.Due to the flat inclined configuration and flat arrangement of the dovetail guides on the modules according to the invention, it is possible without any problem to insert and latch the dovetail-shaped projections of one module into the dovetail-shaped recesses of the adjacent module, analogous to a click connection, in order to connect the modules to one another in a quick and simple manner, in a highly fixed manner.However, by means of the solution according to the invention, it is simultaneously also possible that even after the modules have been first plugged together, they can still be displaced relative to one another along their dovetail connection for positioning purposes.For dismantling the models, the dovetail joints according to the invention between the modules are then detached from one another again simply and without damage solely by pulling apart and / or pulling apart, i.e. without any tools. According to the invention, further building blocks of the toy building block set are formed by multiplying the square basic grid of the basic rock by multiple linear alignments, and that designs of these building blocks can have only one or no end wall, and that, for example, when doubling the basic grid of the basic variant, from the three designs of the square basic variant, three further designs of a double stone are formed, which are constructed analogously to the three designs of the square basic variant such that the double stone has two end walls 16, wherein at least one of the end walls 16 between the two side walls is bent out over the guide height H of the receiving webs 13, and that a double corner stone 4, which is illustrated in FIGS. 4.1 to 4.4, has only one end wall 16, and instead of the second end wall of the double brick 4, there are arranged two spaced-apart receiving webs 13 which together form a dovetail-shaped guide groove having a guide height H and a guide width B, wherein in the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11 there are again arranged spaced-apart latching grooves 14.According to the invention, a double connector block 1, as shown in FIGS. 3.1 to 3.5, has no end wall 16, analogous to the base connector block 2, wherein, instead of the end wall of the double corner block 4, also here two spaced-apart receiving webs 13 are arranged, which together form a dovetail-shaped guide groove having a guide height H and a guide width B, wherein the spaced-apart latching grooves 14 are arranged in the dovetail guide surfaces 10 of the receiving webs 13 of the side walls 11.In these designs as well, the design of the dovetail guides according to the invention enables a high-strength connection of the modules according to the invention, by plugging and / or sliding, with the other modules of the module box according to the invention.Due to the flat inclined configuration and flat arrangement of the dovetail guides on the modules according to the invention, it is possible without any problem to insert and latch the dovetail-shaped projections of one module into the dovetail-shaped recesses of the adjacent module, analogous to a click connection, in order to connect the modules to one another in a quick and simple manner, in a highly fixed manner.However, by means of the solution according to the invention, it is simultaneously also possible that even after the modules have been first plugged together, they can still be displaced relative to one another along their dovetail connection for positioning purposes.For dismantling the models, the dovetail joints according to the invention between the modules are then detached from one another again simply and without damage solely by pulling apart and / or pushing apart, i.e. without any tools. It is characteristic that a further module of the toy module set is the adapter block 3, which is illustrated in FIGS. 6.1 to 6.3, which is formed by an adapter plate 17 on which two dovetail webs 9

essential that the two dovetail webs 9 arranged on the adapter plate 17 are arranged and dimensioned analogously to those on the base block, i.e. that the dovetail webs 9 always have the guide height H in terms of height dimension and the guide width B in terms of length dimension, and that the two dovetail webs 9, on account of their dimensioning, always form guide webs with a guide width B which are offset relative to one another by 90° both in the longitudinal direction and in the transverse direction of the dovetail webs 9, wherein, analogously to the base block, all 4 walls of the end faces of the two dovetail webs 9 are arranged as dovetail guide surfaces 10 at an inclination with respect to the perpendicular by the guide angle α which is in the range of 2° to 5°, and also the side walls of the longitudinal sides of the two mutually adjacent dovetail webs 9, which side walls are formed as dovetail guide surfaces 10, are spaced apart from one another by the web spacing W and form a dovetail-shaped guide groove with a width corresponding to 2 times the wall thickness T.The connection of an adapter brick 3 to one or more modules is effected on the one hand by engaging the dovetail guide surfaces 10 of the adapter brick 3 arranged on the adapter plate 17 in the dovetail guide surfaces 10 of the receiving webs 13 of another module and / or on the other hand by engaging

latching grooves 14 are, for example, embodied as partially circular, as illustrated in the present exemplary embodiment, and have a latching depth N and a latching radius R.Due to the presence of the latching grooves 14 on / in the guide webs of the modules, it is possible to position the adapter block 3 provided with the latching knobs 15 assigned to the latching grooves 14 in a positionally fixed manner in the guide webs of the other modules such that all further modules arranged on the adapter block 3 are also fixed exactly in position on the model on the model.It is also important that

webs 13 of another module also takes place by means of the dovetail guide surfaces 10 of the dovetail edge web / s 20.Further modules according to the invention can be positively connected to the respective modules of the module set according to the invention on up to four sides even in the vertical direction (see FIG. 9 ) but also by longitudinal and even transverse structures (see FIGS. 1 and 2 ).In this case, all modules of the module set according to the invention have in common the design according to the invention of the dovetail guides, which enables a high-strength connection of the modules according to the invention to one another by plugging and / or sliding.Due to the flat inclined configuration and flat arrangement of the dovetail guides on the modules according to the

that along the length dimension, Dovetail guide surfaces (10) are arranged on both sides of the adapter plate (17), said dovetail guide surfaces being inclined with respect to the perpendicular by the guide angle (α) which lies in the range from 2° to 5°, and - the two other side surfaces, the adapter end surfaces 21, of the adapter plate (17), which run parallel to the central longitudinal axes of the dovetail webs (9), are not designed as dovetail guide surfaces (10), and - the two dovetail webs (9) arranged on the adapter plate (17) are arranged and dimensioned in the same way as on the base brick, i.e. the dovetail webs (9) always have the guide height (H) in terms of height dimension and the guide width (B) in terms of length dimension, and in that the two dovetail webs (9), on account of their dimensioning with one another, form guide webs with a guide width (B) which are offset by 90° with respect to both the longitudinal direction and the transverse direction of the dovetail webs (9), and - in analogy to the base brick, all 4 walls of the end faces of the two dovetail webs (9) are arranged, inclined with respect to the perpendicular by the guide angle (α) which is in the range from 2° to 5°, as dovetail guide surfaces (10), and also the side walls, formed as dovetail guide surfaces (10), of the longitudinal sides of the two mutually adjacent dovetail webs (9) are spaced apart from one another by the web spacing (W) and form with respect to one another a dovetail-shaped guide groove which corresponds in its width to 2 times the wall thickness (T), and -
