Description

The application relates to a composite module of six blocks or eight blocks and an alignment device for aligning the blocks. From the DE 10 2009 002 361 A1 or B4 is a composite block known.
It is an object of the invention to provide a simple, in particular material-saving, composite component to be produced, which nevertheless preferably has a high stability and which preferably can also be disassembled in a simple manner. In addition, associated alignment devices should be specified.
This object is achieved by a composite module according to claim 1. Further developments are specified in the subclaims. The object related to the alignment device is achieved by the alignment devices according to the subordinate claims.
The composite module may contain at least six modules and at least one alignment device surrounded by the modules. The alignment device can align the six blocks or aligns the six blocks such that the surface normals of at least one nub or multi-nub planted areas of the blocks point in at least six mutually different directions.
By using an additional inner alignment device, no external alignment device is required when assembling the composite module. Furthermore, the alignment device can assume a holding function, in particular due to a clamping effect. Thus, in addition to the alignment no additional connection means are required, such as an adhesive, screws, etc.
The alignment can be made as material-saving. This is not only a cost factor, but also a time factor in 3D printing with the extruder moving during printing, and in the printing of the moving print platform. The printing platform can be moved Vertikicherweise in 3D printing with filament in two axes, which are preferably perpendicular to each other.
The blocks are preferably clamping blocks, which can be connected to each other by clamping or press fit. In this context is also spoken of fits. The clamping strength depends on the strength of the overlap of both components in a known manner. Alternatively or additionally, the clamping strength can be easily determined empirically by experiment. Known building blocks of this type are, for example, building blocks of the brands Lego, Klix, QB, mini plug, Bestlock, etc., as well as building blocks without brand names. The clamping force between the components can be more than 1 Newton, and in particular less than 10 Newton. These clamping forces can also be used for the Clamping force between the alignment and a plugged it block apply.

The surface normal is defined, for example, by a plane which contains the upper, usually circular surface of the nubs of a building block. Alternatively, for example, reference may also be made to the plane in which the base surfaces of the dimples lie, i. where the nub (s) begin or start at the block.

• es wird ein Bauen in sechs Richtungen bezogen auf einen Verbundbaustein ermöglicht, d.h. vier Richtungen mehr als bei einem bekannten Baustein,
• die Bausteine können ebenfalls durch Klemmsitz an der Ausrichtvorrichtung befestigt werden, wodurch die Bausteine nicht verändert werden müssen und auch ein Rückbau möglich ist, bei dem die Bausteine wieder separat von der Ausrichtvorrichtung verwendet werden, und
• eine überraschend hohe Stabilität des nur zusammengesteckten Verbundbausteins im Vergleich zur Stabilität der Ausrichtvorrichtung, insbesondere dann, wenn die Bausteine aneinander liegen.

The technical effects of the composite are:

• it is possible to build in six directions with respect to a composite module, ie four directions more than in a known module,
• the blocks can also be attached to the alignment device by means of a clamping fit, whereby the blocks need not be changed and also a dismantling is possible in which the blocks are used again separately from the alignment device, and
• a surprisingly high stability of the only assembled composite module compared to the stability of the alignment, especially when the blocks are adjacent to each other.

If there are several nubs on a block, they can be aligned in a row along a straight line. In the case of an even number of nubs on a block, the nubs may also be aligned at a plurality of mutually parallel rows, each lying along a straight line. For example. there can be two rows. The blocks of the composite block can all have the same number of nubs each. Alternatively, some blocks may have a different number of pegs than other blocks of the same composite block. The composite module may include at least two or at least three separate alignment devices, wherein the alignment devices or at least two alignment devices preferably have the same shape with each other.

Thus, for example, alignment devices can be used which have been produced by simple production methods, for example with 3D filament printing, where printing has been done without excessive overhangs, so that no support material is required, which differs from the material of the alignment device and / or which later would be separated again from the alignment device. Alternatively, more complex printing methods can be used, such as injection pressure or powder pressure.

The manufacturing logistics are simplified when only one type of alignment devices is used in the composite building block. Multiple alignment devices can be too much stable composite modules lead, especially if each module is mounted in duplicate on one or more alignment devices.

Thus, components of the composite component surrounded by other components are preferably arranged on respectively at least two alignment devices in order to increase the mechanical stability of the composite component and in particular to prevent twisting of the components when pressure is applied.

Alternatively, the composite module may also contain only one alignment device. This development leads to a simpler manufacturing logistics and easier assembly of the composite module.

The building blocks of the composite module may each contain at least one hollow cylinder, which is in mechanical engagement with one end of the alignment device, in particular by a press fit. Thus, there is a simple attachment for the blocks of the composite block. The attachment also allows automatic adjustment and / or centering of the blocks of the composite block.

A gap may be present between each end of the alignment device and the bottom of a hollow cylinder into which the respective end engages. Dimensions for the gap are mentioned below.

• mit einer ersten freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine erste Richtung zeigt,
• einer zweiten freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine zur ersten Richtung entgegen gesetzte zweite Richtung zeigt,
• einer dritten freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine im Winkel von 90 Grad oder von etwa 90 Grad zur ersten Richtung liegende dritte Richtung zeigt,
• einer vierten freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine zur dritten Richtung entgegen gesetzte vierte Richtung zeigt,
• einer fünften freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine fünfte Richtung zeigt, die im Winkel von 90 Grad oder von etwa 90 Grad zur ersten Richtung und die im Winkel von 90 Grad oder von etwa 90 Grad zur dritten Richtung liegt, sowie
• einer sechsten freien Anbaufläche des Verbundbausteins, deren Flächennormale in eine zur fünften Richtung entgegen gesetzte sechste Richtung zeigt.

The compound module can be executed:

• with a first free acreage of the composite block whose surface normal points in a first direction,
• a second free mounting surface of the composite module whose surface normal points in a second direction opposite to the first direction,
• a third free mounting surface of the composite module whose surface normal points in a third direction lying at an angle of 90 degrees or about 90 degrees to the first direction,
• a fourth free mounting surface of the composite module whose surface normal points in a direction opposite to the third direction fourth direction,
• a fifth free mounting surface of the composite device whose surface normal points in a fifth direction which is at an angle of 90 degrees or about 90 degrees to the first direction and which is at an angle of 90 degrees or about 90 degrees to the third direction;
• a sixth free acreage of the composite block whose surface normal points in a direction opposite to the fifth direction sixth direction.

This can be grown on the composite module along all six axis directions of a Cartesian or rectangular coordinate system. For example, the term "about 90 degrees" may encompass the range of 89 degrees to 91 degrees.

• entlang einer ersten Geraden ein erster Hauptkörper in der Ausrichtvorrichtung enthalten ist, der vorzugsweise zylinderförmig und der vorzugsweise langgestreckt ist,
• quer zu der ersten Gerade an einer ersten Position des Hauptkörpers beidseitig des Hauptkörpers entlang einer zweiten Geraden ein erster Querkörper angeordnet ist, der vorzugsweise zylinderförmig ist und der vorzugsweise langgestreckt ist, wobei die erste Gerade und die zweite Gerade vorzugsweise einen Winkel von 90 Grad oder von etwa 90 Grad bilden,
• quer zu der ersten Gerade an einer zweiten Position des Hauptkörpers mit Abstand zur ersten Position beidseitig des Hauptkörpers entlang einer dritten Geraden ein zweiter Querkörper angeordnet ist, der parallel zu dem ersten Querkörper liegt und der vorzugsweise zylinderförmig ist und der vorzugsweise langgestreckt ist,
• an der ersten Position beidseitig oder einseitig des Hauptkörpers entlang einer vierten Geraden ein dritter Querkörper angeordnet ist, der vorzugsweise zylinderförmig ist und der vorzugsweise langgestreckt ist, wobei die vierte Gerade vorzugsweise im Winkel von 90 Grad oder von etwa 90 Grad zu einer Ebene liegt, welche die erste Gerade und die zweite Gerade enthält,
• an der zweiten Position beidseitig oder einseitig des Hauptkörpers entlang einer fünften Geraden ein vierter Querkörper angeordnet ist, der parallel zu dem dritten Querkörper liegt und der vorzugsweise zylinderförmig ist und der vorzugsweise langgestreckt ist.

The at least one alignment device may be implemented by:

• along a first straight line a first main body is contained in the alignment device, which is preferably cylindrical and which is preferably elongated,
• transverse to the first straight line at a first position of the main body on both sides of the main body along a second straight line a first transverse body is arranged, which is preferably cylindrical and which is preferably elongated, wherein the first straight line and the second straight line preferably at an angle of 90 degrees or form about 90 degrees,
• a second transverse body is arranged transversely to the first straight line at a second position of the main body at a distance from the first position on both sides of the main body along a third straight line, which is parallel to the first transverse body and which is preferably cylindrical and which is preferably elongated,
• at the first position on both sides or one side of the main body along a fourth straight line a third transverse body is arranged, which is preferably cylindrical and which is preferably elongated, wherein the fourth straight is preferably at an angle of 90 degrees or approximately 90 degrees to a plane which contains the first straight line and the second straight line,
• at the second position on both sides or one side of the main body along a fifth straight line a fourth transverse body is arranged, which is parallel to the third transverse body and which is preferably cylindrical and which is preferably elongated.

Thus, the alignment device forms a kind of skeleton or framework in which other bodies laterally extend away from one main body.

"Extended" may mean that the length is, for example, greater than twice or greater than three times the maximum width or the radius in a cylinder.

All cylindrical bodies of the alignment device preferably have the same radius with each other.

The developments mentioned above with preferably also apply to the alignment device explained and claimed below alone, that is to say when no clamping modules have yet been arranged on the alignment device.

If the fourth cross member and the fifth cross member each extend only on one side of the main body, it is preferably the same side, i.e., the other side. There is no offset across the main body.

The alignment body can be produced in a simple manner, in particular material-saving. Suitable manufacturing methods are injection molding or sequential 3D (3-dimensional) printing layer by layer, in particular using a plastic wire or plastic filament, which is applied in particular by an extruder movably arranged on the printing device. Alternatively, a sequential 3D printing process may be used in which a powder is applied layer by layer and solidified by a laser or other energy source.

In one embodiment, two such alignment devices are used in the composite module, in particular if some transverse webs are only one side of the main body.

When using the alignment device (s), an extremely compact composite component block is produced. The composite module withstands high mechanical loads without the comparatively delicate alignment device being able to break. This is exacerbated when, for example, one or more inner building blocks directly abut the side walls of the alignment device with the bottoms and are surrounded by other building blocks, the bottoms of which bear against the inner building blocks, so that the outer building blocks are significantly affected by pressure support the inner building blocks and not on the alignment.

In addition, the composite module can be designed so that there is a gap between the free end of a transverse body or the free ends of the main body and an inner top surface of the adjacent block. The longitudinal axes of the alignment then take themselves no longitudinal pressure or only together with the inner stones. Without a gap, the compressive forces significantly affect the inner building blocks, which also leads to a high stability.

The inner building blocks are supported on the alignment device with external pressure on them. If there is a gap between the transverse bodies, to which an inner building block is fastened, and an inner cover surface of the inner building block, then the transverse body does not have to absorb longitudinal compressive forces. Without a gap, the pressure forces act transversely to the alignment, which also leads to a high stability.

A gap between the ends of the alignment device and the infected blocks also leads to a good, in particular gap-free contiguous to each other of the blocks. When pressure on the blocks also such a gap would be closed. Possibly. The module also shifts on the transverse body or the main body along the central axis of the transverse body or of the main body.

The building blocks may be arranged in the composite building block such that at least eight recessed edges form between the building blocks, on which one side wall of an edge-forming building block is covered by at least 50 percent of the outwardly facing surface by another building block forming the edge. For example, in the case of an eight-block module with four nubs each, the edges can be set back in two mutually parallel rows by at most four millimeters relative to a side surface of a module. The edges lead to a well-manageable module with sufficiently large mating surfaces that facilitate pressing against other blocks or to a composite block explained below. In addition, these edges only arise when the blocks are placed close enough together, which increases the stability of the composite block.

The stability of the composite module is increased by the overlap of the stones at the recessed edges, as has already been explained in more detail with reference to compressive forces.

The blocks of the composite module can have at least one or all of the following dimensions in a range of plus or minus one millimeter: length 31.8 millimeters, width 15.8 millimeters, height without nubs 9.6 millimeters. Thus, the most common type of terminal block with eight knobs in two rows can be used for the composite module, with compatibility with commercial stones by the dimensions mentioned in a simple way is achieved. Alternatively apply to larger components in the market: length 63.7 millimeters, width 31.7 millimeters, height without nubs 19.2 millimeters. These two groups of dimensions also apply to the alternative composite building blocks mentioned below.

The building blocks may preferably be made of plastic or contain plastic, in particular of an ABS (acrylonitrile-butadiene-styrene) material. But also readily biodegradable building blocks from corn starch or PLA (polyactide) can be used.

The at least one alignment device may have at least one or all of the following dimensions in a range of plus or minus three millimeters:
Length 47 mm, width 20 mm, height 18 mm. The result is an alignment, which is suitable for aligning typical and widely used building blocks.

The at least one alignment device may preferably be made of plastic or contain plastic, in particular of an ABS material or of a PLA material. ABS is slightly more flexible than PLA and results in very good clamp connections between the alignment device and the building blocks. PLA is the abbreviation for polyactide and is obtained, for example, from corn starch, which facilitates the biodegradation and still allows good clamping connections.

The ends of the alignment device can be conical, in particular with an inclination angle of less than 1 degree or less than 0.5 degrees, but greater than 0.1 degrees. The conical ends facilitate the assembly and possibly also the disassembly of the composite module. Nevertheless, a secure fit of the blocks on the alignment is still possible.

However, other measures may be taken to facilitate assembly and / or increase the nip between the alignment device, e.g. Forming ribs along the longitudinal axes, as it is known, for example, from Potentiometerachsen ago.

In a first alternative of the composite module, the at least one alignment device may include a preferably frame-shaped main body, which preferably has a rectangular or square base. On the main body, two longitudinal pins can be arranged along a first straight line, which are preferably cylindrical or cross-shaped. On both sides of the main body, two first transverse pins can be arranged along a second straight line, which are preferably cylindrical or cross-shaped. The second straight line can lie transversely to the first straight line at a first position of the first straight line. The first straight line and the second straight line may preferably form an angle of 90 degrees or about 90 degrees, wherein, for example, may mean in the range of 89 to 91 degrees. On both sides of the main body can be arranged along a third straight line, two second transverse pin, which are preferably formed cylindrical or cross-shaped. The third straight line can lie transversely to the first straight line at a second position of the first straight line at a distance from the first position, wherein the third straight line can lie parallel to the second straight line. On the main body can be arranged along a fourth straight line, a third transverse pin, which is preferably cylindrical or cross-shaped. The fourth straight line may be at the first position of the first straight line. The fourth straight line may preferably be at an angle of 90 degrees or about 90 degrees to a plane containing the first straight line and the second straight line. On the main body may be arranged along a fifth straight line, a fourth transverse pin, which is parallel to the third transverse pin and which is preferably cylindrical or cross-shaped. The fifth straight line can be at the second position.

Thus, the alignment device is compact as a building block. For example. In addition to the longitudinal pins and the transverse pins, two or even three outer dimensions of the alignment device may correspond to external dimensions (length, width, height without nubs) of a module, in particular a module with half the height of a standard module having two by four nubs. This results in a simple construction with the alignment device according to the first alternative, in particular also during the assembly of a 3D (three-dimensional) building block.

"Frame-shaped" may mean that the main body includes a peripheral frame. The frame may include a median plane that is transverse to the frame. Thus, four flat circumferential or outer webs may be present, which, for example, enclose a middle wall or a plurality of middle walls or recesses. This results in approximately uniform wall thicknesses, which is advantageous for injection molding. Footbridges can further strengthen the frame. In place of the frame shape and a cuboid shape could be used, for example, in a 3D printing. The "footprint" refers to "the footprint of the frame when the tenons are removed at the largest in terms of area.

In a second alternative, the alignment device may include a preferably frame-shaped main body, which also preferably has a rectangular or square base. On the main body, two longitudinal pins can be arranged along a first straight line, which are preferably cylindrical or cross-shaped. On both sides of the main body can be arranged along a second straight line two first knobs, which are preferably formed cylindrical or hollow cylindrical. The second straight line may be transverse to the first straight line with a distance greater than 1 millimeter to a first position of the first straight line. On both sides of the main body can be arranged along a third straight line two second knobs, which are preferably formed cylindrical or hollow cylindrical. The third straight line can lie transversely to the first straight line with a distance greater than 1 millimeter to a second position of the first straight line, which lies at a distance from the first position. The third straight line can lie parallel to the second straight line. On the main body can be arranged along a fourth straight line, a first transverse pin, which is preferably cylindrical or cross-shaped. The fourth straight line may be at the first position of the first straight line. The fourth straight line may preferably be at an angle of 90 degrees or about 90 degrees to the first straight line. On the main body can be arranged along a fifth straight line, a second transverse pin, which is parallel to the third transverse pin and which is preferably cylindrical or cross-shaped. The fifth straight line can be at the second position.

The result is an alignment device that is compact as a building block. The building block character is further supported by the nubs. It also results in a simple construction according to the second alternative, in particular also during the assembly of a 3D (three-dimensional) building block. The directions of the straight lines are in particular such that the composite module with the features of claim 1 results.

Also in the second alternative, "frame-shaped" may mean that the main body includes a peripheral frame. The frame may include a median plane that is transverse to the frame. Thus, four flat circumferential or outer webs may be present, which, for example, enclose a middle wall or a plurality of middle walls or recesses. This results in approximately uniform wall thicknesses, which is advantageous for injection molding. Footbridges can further strengthen the frame. In place of the frame shape and a cuboid shape could be used, for example, in a 3D printing. The "footprint" refers to "the footprint of the frame when the tenons are removed at the largest in terms of area.

The composite building block can be free of an adhesive, in particular an adhesive, which is arranged between the alignment device and the building blocks. In this way, the composite module can be produced in a simple manner and, if necessary, also dismantled in a simple manner, in particular without the use of tools and / or without damage to the components or contamination of the surface of the components.

In addition, however, an adhesive can be used, in particular an acrylate-based adhesive, as is the case, for example, with commercial instant adhesives. Thus, a detachment of blocks of the composite module can be effectively prevented, wherein the strength is increased in terms of tensile forces by the adhesive. With regard to the compressive forces of the adhesive has a lower effect than with respect to the tensile forces because at pressure forces as explained above, a great stability is present. This allows an economical and therefore cost-effective use of the adhesive.

Alternatively or additionally, the alignment device of the composite module may have been produced by a 3D filament printing method, in particular without using an additional support material, preferably without support material, which differs from the material of the alignment device and / or which would later be separated again from the alignment device. Thus, it is easy and saves material and thus fast. Post-processing steps are eliminated or reduced. Injection molding methods can also be used to make the alignment devices.

For all of the above-described composite modules, there can be exactly six components, with two of the six components each having at least one anti-rotation device against one Twist are secured, preferably with an anti-rotation, which has a different structure than the two longitudinal pins.

• mit einem halbem Zapfen, z.B. kreuzförmig oder zylinderförmig, im Vergleich zu einem Längszapfen, oder
• als Steg der in einen Hohlzylinder eingreift, der dem Hohlzylinder benachbart ist, in den der Längszapfen eingreift, oder
• mit einem Kreissegmentquerschnitt, insbesondere einem Kreissegmentquerschnitt der kleiner als ein Halbkreis ist, um bspw. wahlweise den Aufbau eines Verbundbausteins aus sechs Bausteinen oder aus acht Bausteinen zu ermöglichen.

The rotation can be realized, for example:

• with a half pin, for example cross-shaped or cylindrical, in comparison to a longitudinal pin, or
• as a web which engages in a hollow cylinder which is adjacent to the hollow cylinder, in which engages the longitudinal pin, or
• with a circular segment cross-section, in particular a circular segment cross-section which is smaller than a semicircle, in order, for example, optionally to allow the construction of a composite component of six components or of eight components.

The anti-rotation can be designed with a smaller length than the longitudinal pin, for example. With a length which is smaller than half the length of the longitudinal pin.

Webs or flats on the inner sides of the hollow cylinder in the blocks can also counteract excessive rotation.

In the case of all the composite components explained above, another transverse pin can also be arranged along the fourth straight line and another transverse pin can also be arranged along the fifth straight line, preferably further transverse pins which are cylindrical or cross-shaped. The other transverse pins are used to attach the sixth block.

In all of the above-described composite building blocks, the frame-shaped main body may surround a preferably rectangular center wall or a plurality of preferably rectangular center walls, preferably on both sides of the center wall or the center walls. The center wall may have, together with the frame, a base area that corresponds to the base area of a building block that is plugged or inserted into the alignment device.

• mit einem sich entlang einer ersten Geraden erstreckenden ersten Hauptkörper,
• einem quer zu der ersten Gerade an einer ersten Position des Hauptkörpers beidseitig des Hauptkörpers entlang einer zweiten Geraden angeordneten ersten Querkörper, der vorzugsweise zylinderförmig ist und der vorzugsweise langgestreckt ist, wobei die erste Gerade und die zweite Gerade vorzugsweise einen Winkel von 90 Grad oder von etwa 90 Grad bilden,
• einem quer zu der ersten Gerade an einer zweiten Position des Hauptkörpers mit Abstand zur ersten Position beidseitig des Hauptkörpers entlang einer dritten Geraden angeordneten zweiten Querkörper, der parallel zu dem ersten Querkörper liegt,
• einem an der ersten Position beidseitig oder einseitig des Hauptkörpers entlang einer vierten Geraden angeordneten dritten Querkörper, der im Winkel von 90 Grad oder von etwa 90 Grad zu einer Ebene liegt, welche die erste Gerade und die zweite Gerade enthält,
• einem an der zweiten Position beidseitig oder einseitig des Hauptkörpers entlang einer fünften Geraden angeordneten vierten Querkörper, der parallel zu dem dritten Querkörper liegt.

An alignment device for aligning blocks may be implemented:

• with a first main body extending along a first straight line,
• a first transverse body arranged transversely to the first straight line at a first position of the main body on both sides of the main body along a second straight line, which is preferably cylindrical and which is preferably elongated, the first straight line and the second straight line preferably at an angle of 90 degrees or approximately Make 90 degrees,
• a second transverse body which is parallel to the first transverse body and is arranged at a second position of the main body at a second position of the main body at a distance from the first straight line on both sides of the main body along a third straight line,
• a third transverse body disposed at the first position on either or both sides of the main body along a fourth straight line which is at an angle of 90 degrees or approximately 90 degrees to a plane containing the first straight line and the second straight line,
• a arranged at the second position on both sides or one side of the main body along a fifth straight fourth transverse body, which is parallel to the third transverse body.

In an alternative of the alignment device, the at least one alignment device may comprise a preferably frame-shaped main body, which preferably has a rectangular or square base. On the main body, two longitudinal pins can be arranged along a first straight line, which are preferably cylindrical or cross-shaped. On both sides of the main body, two first transverse pins can be arranged along a second straight line, which are preferably cylindrical or cross-shaped. The second straight line can lie transversely to the first straight line at a first position of the first straight line. The first straight line and the second straight line may preferably form an angle of 90 degrees or about 90 degrees, with e.g. in the range of 89 to 91 degrees. On both sides of the main body can be arranged along a third straight line, two second transverse pin, which are preferably formed cylindrical or cross-shaped. The third straight line can lie transversely to the first straight line at a second position of the first straight line at a distance from the first position, wherein the third straight line can lie parallel to the second straight line. On the main body can be arranged along a fourth straight line, a third transverse pin, which is preferably cylindrical or cross-shaped. The fourth straight line may be at the first position of the first straight line. The fourth straight line may preferably be at an angle of 90 degrees or about 90 degrees to a plane containing the first straight line and the second straight line. On the main body can be arranged along a fifth straight line, a fourth transverse pin, which is parallel to the third transverse pin and which is preferably cylindrical and which is preferably elongated. The fifth straight line can be at the second position. Thus, the alignment device is compact as a building block. For example. In addition to the longitudinal pins and the transverse pins, two or even three outer dimensions of the alignment device may correspond to external dimensions (length, width, height without nubs) of a module, in particular a module with half the height of a standard module having two by four nubs. This results in a simple construction with the alignment device according to the first alternative, in particular also during the assembly of a 3D (three-dimensional) building block.

For the separate alignment devices, the technical effects mentioned above for the alignment devices of the composite apply. In addition, it is possible to send the separate alignment devices separately from the blocks, in particular so that for the production of the composite block already existing at the receiver blocks be used. The assembly effort is therefore carried out by the end user.

The ends of the alignment device may be conical, in particular with an inclination angle of less than 1 degree or less than 0.5 degrees, but greater than 0.1 degrees. Thus, the technical effects mentioned above for conical ends also apply to the alignment device.

Alternatively or additionally, the alignment device has been produced by a 3D filament printing method, in particular without using an additional support material, preferably without support material, which differs from the material of the alignment device and / or which would later be separated again from the alignment device. Thus, it is easy and saves material and thus fast. Post-processing steps are eliminated or reduced. Alternatively, an injection molding method is used to manufacture one of the alignment devices.

The above embodiments and embodiments may be combined with each other and with the examples of the figures described below as desired. If "can" is used in this application, this means both the technical possibility and an actual technical realization.

• einen einseitig des Hauptkörpers HK an der Position P2 angeordneten zylinderförmigen Querkörper Q4, dessen Mittelachse ebenfalls in z-Richtung liegt.

The alignment device AV1 has:

• a cylindrical main body HK whose central axis lies in the x-direction,
• a cylindrical transverse body Q1 arranged on both sides of the main body HK at a position P1, the central axis of which lies in the y-direction,
• a cylindrical transverse body Q2 arranged on both sides of the main body HK at a position P2, the central axis of which also lies in the y-direction,
• a cylinder-shaped transverse body Q3 arranged on one side of the main body HK at the position P1, the central axis of which lies in the z-direction, and
• a cylindrical transverse body Q4 arranged on one side of the main body HK at the position P2, whose central axis likewise lies in the z-direction.

The positions P1 and P2 are selected so that the transverse bodies Q1 and Q2, for example, in the outer hollow cylinder, for example. Z1 and Z3, a block, e.g. B1, can intervene.

The FIG. 3 shows a composite module V1 with two alignment devices AV1 and AV2 in front view. A Cartesian coordinate system 30 has an x-axis, a y-axis and a z-axis, which point in this order in the coordinate directions x, y, z. The x-axis and z-axis are in the sheet plane, with the x-axis pointing to the right and the z-axis up. The y-axis points vertically into the leaf plane of the FIG. 3 into what is indicated by a cross, for example, the springs of an arrow directed away from the viewer to illustrate.

The composite module V1 contains the alignment devices AV1 and AV2. The alignment device AV1 lies to the right of the alignment device AV2, the main body HK1 of the alignment device AV1 being arranged parallel to the main body HK2 of the alignment device AV2. In addition, the lateral bodies Q3a and Q4a of the alignment device AV1 arranged on one side of the main body HK1 are directed away from the transverse bodies Q3b and Q4b of the alignment device AV2 arranged on one side on the main body HK2. The transverse bodies Q3a and Q4a engage in the hollow cylinders HZ1 and HZ3 of the module B1 in a clamping fit. The transverse bodies Q3b and Q4b engage in the further outward set hollow cylinder of a block B2 in a press fit.

The ends of the transverse bodies Q1a and Q2a of the alignment device AV1 directed towards the viewer each engage in the right cylinder of a building block B3b or B3a. The ends of the transverse bodies Q1b and Q2b of the alignment device AV2 which are directed towards the observer respectively engage in the left cylinder of a building block B3b or B3a.

The facing away from the viewer ends of the transverse body Q1a and Q2a of the alignment device AV1 each engage in the right cylinder of a block B4b or B4a, see FIG. 4 , The viewer-directed ends of the transverse bodies Q1b and Q2b of the alignment device AV2 respectively engage with the left cylinder of the package B4b and B4a, respectively FIG. 4 ,

By this arrangement of the blocks B3a and B3b or of the blocks B4a and B4b, see FIG. 4 , the composite module V1 can not turn in on itself. Alternatively, the modules B3a and B3b (B3 for short) as well as the modules B4a and B4b (B4 for short) can also only be plugged onto one of the alignment devices AV1, AV2, ie the longitudinal axes of the modules B3 and B4 are parallel to the central axis of the main body HK1, HK2 of the alignment devices AV1, AV2. In this case, another measure can prevent a rotation of the blocks B3 or B4.

That in the FIG. 3 The end of the alignment device AV1 shown above engages in the right hollow cylinder of a block B5. That in the FIG. 3 The end of the alignment device AV2 shown above engages in the left hollow cylinder of the module B5.

That in the FIG. 3 The bottom of the alignment device AV1 shown below engages the right hollow cylinder of a block B6. That in the FIG. 3 The end of the alignment device AV2 shown below engages the left hollow cylinder of the package B6.

When assembling the composite module V1, for example, the procedure is as follows. On a flat surface first in the FIG. 3 not shown building blocks B4a and B4b with their openings facing upward in an orientation that corresponds to the illustrated orientation of the blocks B3a and B3b, ie long sides extend in the x-direction. Thereafter, the alignment device AV1 is inserted into the right cylinders of the blocks B4a and B4b and pressed until it abuts the blocks B4a and B4b. The alignment device AV2 is inserted into the left cylinders of the blocks B4a and B4b and pressed until it abuts the blocks B4a and B4b.

Thereafter, for example, the module B3a is placed on the upwardly directed ends of the transverse bodies Q2a and Q2b and pressed until it abuts the main body HK1 or HK2. Subsequently, for example, the module B3b is placed on the upwardly directed ends of the transverse bodies Q1a and Q1b until it strikes the main body HK1 or HK2.

Thereafter, the module B2 can be placed on the right exposed ends of the transverse body Q3a and Q4a until it abuts the right side walls of the blocks B3a, B3b, B4a and B4b.

Furthermore, then the block B5 on the in the FIG. 3 Inserted above exposed ends of the main body HK1 and HK2 until it strikes the long side walls of the blocks B3a and B4a.

Thereafter, the module B1 can be plugged onto the left exposed ends of the transverse body Q3b and Q4b until it abuts the left side walls of the blocks B3a, B3b, B4a and B4b.

Furthermore, then the block B6 on in the FIG. 3 stuck down ends of the main body HK1 and HK2 until it strikes the long side walls of the blocks B3b and B4b.

Thus, the assembly in a few steps can be realized. It is also possible to select a different sequence of assembling the composite module V1 than just explained. For example. For example, the order of assembly of the modules B1, B2, B5 and B6 can be arbitrary.

In the FIG. 3 For example, the distances between the alignment devices AV1 and AV2 on one side and the devices B1 to B6 on the other side are exaggerated to facilitate understanding. In fact, here a clamping seat is used, which does not allow a gap, but requires a certain overlap of adjacent parts.

In the FIG. 3 are further exaggerated large gaps S1 and S2, which are present between the ends of the transverse body Q3a and Q3b and the inner ceiling surface of the module B1 in the cylinder HZ1 and HZ3. These gaps S1 and S2 allow a good fit of the module B1 to the blocks B3a, B3b, B4a, B4b. The gap-free touching of the components B3a, B3b, B4a, B4b by the module B1 is also ensured on the basis of the gaps S1 and S2, if the ends of the transverse bodies Q3a or Q3b are of different lengths with respect to one another, which is, for example, due to inaccurate printing of the Case can be. Also at the other hollow cylinders in which the alignment devices AV1 and AV2 engage, there are gaps on the hollow cylinder bottom corresponding to the gap S1 and the gap S2, respectively. These gaps, for example S1 to S4, may, for example, have a gap width in the range from 0.1 millimeter to 1 millimeter.

The Indian FIG. 3 illustrated connection module V1 can be produced without adhesive. In addition, however, adhesive may also be used to secure building blocks B1 to B6 against overstretching and to avoid bond peeling in the case of tensile forces. The adhesive can be introduced, for example, into the hollow cylinders, eg HZ1, HZ3, in particular into the gaps S1 to S4.

In the FIG. 3 not all nubs N are designated. However, the nubs N5 to N8 of the module B1 are shown. In the FIG. 3 are still shown:

• Surface normals FN1, FN2, FN5 or FN6 at the blocks B1, B2, B5 and B6, respectively,

• Surface normal FN1 in x-direction,
• Surface normal FN2 opposite to the x direction,
• Surface normal FN5 in z-direction, and
• Surface normal FN6 opposite to the z direction.

Arrows 32a, 32b indicate a view from the right, in the following FIG. 4 is shown.

The FIG. 4 shows the in the FIG. 3 shown composite module V1 in side view. Again, the coordinate system 30 is shown. The y-axis and the z-axis are in the leaf plane, with the y-axis pointing to the left and the z-axis pointing upwards. The x-axis is perpendicular to the plane of the page FIG. 3 out, which is indicated by an arrowhead.

In the FIG. 4 are still shown:

• Surface normal FN3 or FN4 at the building block B3a or B4a,
• Acreage AF3 or AF4 on the block B3a or B4a, as well as
• recessed edges K1 and K5 with overlapping of building blocks.

• Flächennormale FN4 entgegen der x-Richtung.

The surface normals FN3 and FN4 point in the following directions:

• Surface normal FN3 in y-direction,
• Surface normal FN4 opposite to the x direction.

The surface normal FN3 also applies to the studded surface of module B3b. Likewise, the surface normal FN4 also applies to the studded surface of the module B4b. The acreage AF3 also extends over the nubs of the two blocks B3a and B3b. Likewise, the acreage AF3 extends over the nubs of the two blocks B4a and B4b.

A gap S3 lies between the end of the transverse body Q2a facing the module B4a and the module B4a. A gap S4 is located between the end of the cross body Q1a facing the module B4b and the module B4b. For the column S3 and S4, what has been said about the gap S1 or S2 applies.

Thus, with the in the Figures 3 and 4 shown composite module V1 are built in six directions, with three directions (eg x, y, z) are exactly opposite to the other three directions (eg -x, -y, -z). The construction along Cartesian coordinates corresponds to the typical construction methods in the construction industry and also the typical spatial conceptions of the people.

The FIG. 5 shows a schematic diagram of the in the Figures 3 and 4 shown alignment devices AV1 and AV2.

In a variant for an alignment device, the alignment devices AV1 and AV2 are connected by a connecting web or by two connecting webs 50, 52 or more than two connecting webs. The connecting webs 50, 52 may be located at the positions P1 and P2, so that the transverse bodies Q3a and Q3b are interconnected by the connecting web 52. The transverse bodies Q4a and Q4b can be interconnected by the connecting web 50. If only one connecting bar is used, it can end in the middle of the main body HK1, HK2.

Furthermore, instead of the connecting webs 50 and 52, alternatively, there may be another alignment device, which is designed like the alignment device AV1 but has no transverse webs Q3a and Q4a. The transverse webs Q1a and Q2a corresponding transverse webs of the other alignment devices and their ends of the main body then engage in each case in the middle cylinder of the blocks, which further increases the stability. However, the further alignment device can also, as explained in the previous paragraph, be connected to the other two alignment devices AV1 and AV2 by means of a web or a plurality of webs.

In a further variant with the connecting webs 50 and 52 and the two alignment devices AV1 and AV2, the transverse bodies Q1a, Q2a, Q1b and Q2b are formed on one side only on the main body HK1 or HK2. With two such alignment devices can then be built composite blocks with 12 blocks, which have two blocks on each side and thus cubic are as the composite module V1. In addition, these two alignment devices can also be connected by two or four further connecting webs.

In all embodiments with composite webs instead of the webs and a composite plate, possibly with recesses of preferably less than 50 volume percent can be used.

The FIG. 6 shows a sketch for an alignment device AV3, which can be used in a composite block of only six blocks. The alignment device AV3 is constructed, except for the deviations explained below, like the alignment device AV1 or AV2, ie there are:

• a main body HK3 corresponding to the main body HK1 and HK2, respectively, and extending along a first straight line,
• a transverse body Q1c lying at a first position of the first straight line which corresponds to the transverse body Q1a or Q1b and which extends along a second straight line which lies at an angle of 90 degrees to the first straight line,
• a transverse body Q2c lying at a second position of the first straight line which corresponds to the transverse body Q2a or Q2b and which extends along a third straight line which is at an angle of 90 degrees to the first straight line and parallel to the second straight line,
• a transverse body Q3c located at the first position of the first straight line, which corresponds to the transverse body Q3a or Q3b on one side of the main body HK3 and which extends along a fourth straight line which is at an angle of 90 degrees to the first straight line and to the second straight line,
• a transverse body Q4c located at the second position of the first straight line, which corresponds to the transverse body Q4a or Q4b on one side of the main body HK3 and which extends along a fifth straight line which lies at an angle of 90 degrees to the first straight line and to the second straight line.

However, the transverse bodies Q3c and Q4c, unlike the transverse bodies Q3a, Q3b and Q4a, Q4b respectively, extend on both sides of the main body HK3 and may be arranged symmetrically with respect to the main body HK3.

• erster Baustein mit seinen beiden äußeren Hohlzylindern an den in der Figur 6 mit Bezugszeichen versehenen Enden der Querkörper Q1c und Q2c,
• zweiter Baustein mit seinen beiden äußeren Hohlzylindern an den in der Figur 6 mit Bezugszeichen versehenen Enden bzw. an den vorderen Enden der Querkörper Q3c und Q4c,
• dritter Baustein mit seinen beiden äußeren Hohlzylindern an den in der Figur 6 nicht mit Bezugszeichen versehenen Enden bzw. an den rechten Enden der Querkörper Q1c und Q2c,
• vierter Baustein mit seinen beiden äußeren Hohlzylindern an den in der Figur 6 nicht mit Bezugszeichen versehenen Enden bzw. an den hinteren Enden der Querkörper Q3c und Q4c,
• fünfter Baustein mit seinem mittleren Hohlzylinder an dem in der Figur 6 mit einem Bezugszeichen versehenen Ende des Hauptkörpers HK3, d.h. am unteren Ende des Hauptkörpers HK3, und
• sechster Baustein mit seinem mittleren Hohlzylinder an dem in der Figur 6 nicht mit einem Bezugszeichen versehenen Ende des Hauptkörpers HK3, d.h. am oberen Ende des Hauptkörpers HK3.

For example. Six eight-block devices can be arranged on the alignment device as follows:

• first building block with its two outer hollow cylinders to those in the FIG. 6 having reference numerals of the transverse bodies Q1c and Q2c,
• second building block with its two outer hollow cylinders to those in the FIG. 6 with reference numerals or at the front ends of the transverse bodies Q3c and Q4c,
• third building block with its two outer hollow cylinders to those in the FIG. 6 unmarked ends or at the right ends of the cross members Q1c and Q2c,
• fourth building block with its two outer hollow cylinders to those in the FIG. 6 unmarked ends and rear ends of the cross members Q3c and Q4c, respectively;
• fifth building block with its middle hollow cylinder at the in the FIG. 6 provided with a reference numeral end of the main body HK3, ie at the lower end of the main body HK3, and
• sixth building block with its central hollow cylinder on the in the FIG. 6 not provided with a reference numeral end of the main body HK3, ie at the upper end of the main body HK3.

In this case, for example, the first building block to fourth building block may have the same distance to a central axis of the main body HK3.

Alternatively, the first building block and the third building block have a smaller distance to a central axis of the main body HK3, ie they are, for example, on the main body HK3. The second module and the fourth module, however, can be a greater distance from the Central axis of the main body HK3 have as the first block or the third block. Thus, the second component and the fourth component can each rest on the first component and on the second component, but not on the main component HK3.

The fifth module and the sixth module can be secured by means of an additional rotation on the alignment device AV3 against rotation, not shown. The rotation can be carried out, for example, including the two outer hollow cylinder of the fifth block or the sixth block, as has been explained above in the introduction. For example. For example, the fifth building block and the sixth building block may be aligned and adjusted so that their longitudinal axes lie along the central axes of the transverse bodies Q3c and Q4c, respectively, when the first building block and the third building block touch the alignment device AV3 but not the second building block and the fourth building block , Thus, as seen in the direction of the central axis of the main body HK3, the fifth block and the sixth block do not project beyond the second block and the third block.

However, the same configuration can also be selected for the fifth and sixth building blocks if the first building block, the second building block, the third building block and the fourth building block each have the same distance to the central axis of the main body HK3, which in the FIG. 6 lies in the vertical direction.

Also in the in the FIG. 6 shown alignment device AV3 may be arranged between the stacked cross members further optional cross member Q5c and Q6c, so that all three hollow cylinders of a side of the alignment device AV3 arranged block with the alignment device AV3 are engaged, which further increases the stability.

The FIG. 7 shows an alternative alignment device AV4. It is a coordinate system 20, see FIG. 2 , corresponding coordinate system 60. The alignment device AV4 has a frame-shaped main body or frame R having a square base. On the frame R, two longitudinal pins Z0a and Z0b are arranged along a first straight line G1, which are cylindrical or cross-shaped as in the example. Alternatively, the longitudinal pins Z0a and Z0b can also be designed in a different way. The straight line G1 lies in the x-direction.

The frame R includes on its side surfaces four flat outer webs AS1 to AS4. In the frame R is a median plane M, which has, for example, the thickness of the outer webs. The upper outer web AS4 and the lower outer web AS2 can connect three optional intermediate webs ZS1 to ZS3 in order to increase the stability of the alignment device AV4. On the back there are optionally the intermediate webs ZS1 to ZS3 corresponding Intermediate webs. In the embodiment shown, the distance between the blocks B3 and B4 can be predetermined by the width of the outer webs AS1 to AS4. The blocks B3 and B4 then specify the distances between the other opposing blocks.

However, the frame R may also be used only as a thin plate, i. without the outer webs AS1 to AS4, be formed, see center plane M. The distance between the blocks B3, B4 of the composite block can be set in this case, for example. Over the length of the pins, there is no gap between pin ends and hollow cylindrical bottoms of the blocks. Alternatively, the distance can be adjusted via other spacers. These spacers are, for example, arranged only in the region of the pins and / or at other suitable locations. The blocks B3 and B4 then again specify the distances between the other opposing blocks.

On both sides of the frame R, two first transverse pins Z1a, Z1b are arranged along a second straight line G2, which are also formed in a cross shape. Alternatively, the transverse pins Z1a and Z1b are formed in another way, e.g. cylindrical. The second straight line G2 lies in the y-direction. The second straight line G2 lies transversely to the first straight line G1 at a first position P1 of the first straight line G1. The first straight line G1 and the second straight line G2 form an angle of 90 degrees.

On both sides of the frame lie along a third straight line G3 two second transverse pins Z2a and Z2b, which are cylindrical, cross-shaped or otherwise formed. The third straight line G3 lies transversely to the first straight line at a second position P2 of the first straight line G1. The second position P2 has a pitch distance to the first position, e.g. 32 millimeters. The grid spacing is, for example, twice the distance between studs of the building blocks, which are plugged into the alignment device AV4. The third straight line G3 is parallel to the second straight line G2.

On the main body or frame R, a third transverse pin Z3 is arranged along a fourth straight line G4, which is preferably cylindrical, cross-shaped or otherwise formed. The fourth straight line G4 may be located at the first position P1 of the first straight line G1. The fourth straight line may preferably lie at an angle of 90 degrees or approximately 90 degrees to a plane, here x-y plane or parallel thereto, which contains the first straight line G1 and the second straight line G2.

On the main body or frame R is located along a fifth straight line G5, a fourth transverse pin Z4, which is parallel to the third transverse pin Z3 and which is preferably cylindrical, cross-shaped or otherwise formed. The fifth straight line G5 is located at the second position P2.

The alignment device AV4 offers both the possibility of using the blocks B3a, B3b, B4a, B4b (two times four pimples) or, alternatively, blocks with two times three pimples instead of these blocks B3a, B3b, B4a, B4b in a composite block V1. The inner edges on the crosses of the pins Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Z4 can also be even more rounded. Alternatively, in each case one cylinder core can be used on the pins Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Z4.

Although the frame R may be wider than the pin Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Z4, it may also be the same width or narrower than the pin Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Be Z4. The ends of the pins Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Z4 can also be sharpened less strongly. It is also possible to use cylindrical or hollow-cylindrical pins Z0a, Z0b, Z1a, Z1b, Z2a, Z2b, Z3 and Z4. For injection molds, suitable radii are selected at the edges of the alignment device AV4.

The alignment device AV4 can also be designed so that the frame R is also symmetrical to the pin Z0a or Z0b, for example. By a corresponding extension downwards in the position according to the FIG. 7 , The base of the frame R may coincide with the base of a building block, which is plugged into the alignment device AV4, in particular on the pin Z1a and Z2a. Other variants are also possible, for example, a shift of the upper frame side to the pin Z0a, Z0b, wherein the alignment device AV4 of the alignment device AV1 is similar.

In a variant with or without corresponding extension of the frame R downwards, there are on the line G4 and on the frame R a pin Z3b and on the line G5 and on the frame R a pin Z4b. It turns out the above hand of the FIG. 6 explained variant. If the extension of the frame R, then the pin Z3b as the pin Z3 is formed. The pin Z4b is formed like the pin Z4. On the other hand, if the frame R is asymmetrical as shown, the pins Z3b, Z4b are made longer in comparison to the length of the pins Z3 and Z4.

Alternatively, instead of two alignment devices AV4, an alignment device which contains sixteen projecting pins on a plate with a square base can also be used in a composite module comprising eight components. This alignment device can be designed by mirroring the alignment device AV4 downwards.

Further alternatively, in place of the pins Z1a, Z1b, Z2a, Z2b also knob arrangements can be used, as they are known from the blocks ago, the knobs protrude with the usual lengths or with greater lengths over the edge of the frame R.

For example. eight studs can be arranged on the side at which the pins Z1a and Z2a are shown. The nubs are not in the places where the pin Z1a or Z2a was in the alignment device AV4, but are arranged around these locations, which is known from the mating of standard building blocks, for example with two times four knobs ago, ie we the same or a similar interface also used in the 3D composite block. Another eight nubs can be arranged on the side at which the in the FIG. 7 concealed pin Z1b and Z2b are arranged. Also on the back then the knobs are not in the places where the pin Z1b or Z2b was in the alignment device AV4, but are arranged around these locations, which is known from the mating of standard components, eg with two times four knobs ago is. Due to the position of the knobs on the modified alignment device, a straight line corresponding to the straight line G2 or a straight line corresponding to the straight line G3 is arranged at a distance from the straight line G1, eg with a distance greater than 1 mm and, for example, less than 15 mm (millimeters). ,

It can also be on a composite block stones, which have mutually different Noppenanzahlen and / or Noppenanordnungen.

If there are no hollow cylinders in the other blocks, there are, for example, solid cylinders. Thus, the alignment is adjusted accordingly, ie to provide with hollow cylinders at their ends. These hollow cylinders can also be made conical, in particular expanding outwards.
