Description

The invention relates to a toy building system for providing a structure comprising toy building elements which can be interconnected to form the structure, which toy building elements comprise beads and a first toy building element. The invention also relates to the use of a toy building system according to the invention for the formation of two- or three-dimensional structures.

Tube beads have been known for many years and have been used to make two-dimensional motifs, by placing the tube beads on prefabricated square, circular or figure-shaped pin plates with small conical pins on the upper side. The square pin plates, for beads of the same size, can sometimes be assembled into larger units and have fixed attachment points. When the motif is finished, the loose tube beads are fused together while still standing on the pin plate. This is done using an iron and ironing paper. The beads are therefore not attached to the pins, as it makes it difficult to remove the fused motif from the pin plate. The pins thus only have the task of holding the beads in a fairly fixed position on the plate. This means partly that there can be very large variation in the dimensions of the beads from production to production, without it meaning anything for the fused motif, and partly that there is therefore a distinct problem for the users in that the beads easily tip over or fall off the plate. , if pushed to the pin plate during use.

Pin plates in figurative form have also been used, with pins on both sides of the plate, where the beads are fixed on the pin plate, so that the motif can be seen from both sides and has twice the width of the bead for the purpose that the motif can stand on its own. Here it is thus intended that the beads should remain on the pin plate and not be built further in the axial direction, as the pins are cylindrical, have a larger diameter than the inner passage of the tube bead and where

DK 180797 B1 2 the length of the pins makes up more than 60% of the inner passage of the pipe bead. DK9300162U3 describes a similar principle, where the tube beads are pressed down over a pin, but where the pin plate here is a square pin plate made of a soft material for the purpose that the user must be able to cut or cut away the excess part of the pin plate when the motif is done. For this purpose, an assembly has been made consisting of two groups of molded pipe beads, which are connected by a larger flexible connecting piece which does not hold the pin plates directly in contact with each other. The joint is here intended to hold two pin plates together, with the pin-free backs facing each other by bending the joint backwards. The joint can also be used when assembling pin plates with pins on both sides. | in both cases the pin plates will only be connected via the flexible part of the joint.

It has also been known to design the fused blanks in such a way that they can subsequently interlock and, for example, hold a motif upright or form a cube, a house or another 3 dimensional object.

Patent DK / EP2729226 shows in the drawing on page 9 item 11 another example of assembly of two items. Here, a technique has been used in which it is the introduced workpiece that adapts to the cylindrical passage in the second workpiece. Here, this is done by the inserted workpiece being tubular and cylindrical with an outside diameter which is smaller than the inside diameter of the passage for the piece of pipe which is to be inside the passage when the pipe is mounted. The rest of the pipe has a diameter outside the passage which is larger than the inside diameter of the passage so that the pipe is locked in the passage. The compression of the outer piece of pipe takes place by making two smaller slots in the pipe section and that the outer ring on the pipe section is designed so that it is pressed in through the passage by compression thereof. This technique is thus suitable for situations where the introduced workpiece can be carried completely

DK 180797 B1 3 through the passage, where the items must be able to be held together even under heavy load and where the items are expected to sit together permanently or for a longer period of time at a time.

Tube beads are available today in several sizes, but different sizes of tube beads are not used in conjunction with each other in the same structure and are not dimensioned in relation to each other.

Pipe beads have also not previously been used to build on top of each other in more layers than what results from using a single pin plate with pins on both sides. The object of the present invention is to develop a modular toy building system with toy building elements which makes it possible to build with pipe beads both axially on top of each other and next to each other in both two-dimensional and three-dimensional structures, where the size and shape of the basic modules can be easily adapted and assembled needs, where it is also possible with the system to use differently dimensioned pipe beads as well as manifold modules with different patterns in the same structure, to process and adapt the individual toy elements and to integrate other materials and components in the structure. The present invention thus makes it possible to use and reuse the same pipe bead indefinitely and in many different contexts and functions, to be able to adapt the shape and size of the individual joint sleeve module to hold two or more upright pipe beads next to each other, e to be able to build with pipe beads both on top of each other in several layers and inside each other in the axial direction of the pipe bead and next to it

DK 180797 B1 4 each other and perpendicular to each other and to be able to use both socket modules and pipe beads of the same as well as different sizes and structures in both directions vertically, horizontally and diagonally to be part of the same structure, e to be able to connect the joint sleeve modules arbitrarily between two joint sleeves, e to be able to add strength, flexibility and mobility to the structure by virtue of the internal channels in the structure as well as the geometry of the circle and thus move substructures up to +/- 180 degrees across the channels axis and +/- 360 degrees around the axis of the channels, e be able to integrate other materials and components in the structure, e be able to use the product in dynamic environments, minimize the need for adult presence and eliminate the need to melt the beads to preserve a structure, This is achieved by arranging the initially mentioned toy building system on the following way:

According to the invention, there is provided a toy building system as indicated in the introduction, and wherein the beads are tube beads, which tube beads are hollow bead tubes with an outer diameter D1 and with a continuous cylindrical passage with diameter d, and that the first toy building element is at least one joint collecting sleeves comprise a hollow sleeve tube delimited by a wall with a circular cross-section and with a first opening and an opposite second opening, as well as an outer and perpendicular to the longitudinal axis of its longitudinal axis annular stop plate with an outer diameter corresponding to the outer diameter D1 of the tube bead, which stop disk distance to the first and second openings is the same and, introduced into the inner passage of the tube bead, must not be longer than half the axial height of the tube bead.

Both

DK 180797 B1 elements are made of a flexible material so that they can work together in the structure.

The designs of the pipe bead and the collecting sleeve thus make it possible for two 5 collecting sleeves to be inserted simultaneously in the openings of a pipe bead with engagement from each side of the inner passage of the pipe bead, whereby further pipe beads and collecting sleeves can now be axially extended in an endless structure. passage in the axial longitudinal direction of the whole structure, which passage is the basis for being able to add various properties and functions to the system.

According to one embodiment, the wall of the manifold is a cylindrical tube comprising two cylindrical pieces of pipe extending externally from each side of the stop washer or the wall of the manifold diverging from the annular stop washer and towards the first opening and the second opening, respectively, to provide two conical pipe pieces. .

The diameter of the inner continuous passage of the sleeve tube is the same in its entire extent for both versions of the sleeve tube.

For the cylindrical pipe pieces, the outside diameter is substantially equal to the inside diameter d of the pipe bead.

While the conical pipe pieces at the stop washer start with an inverted outward conical stub with an inward conical stub at the top, which sleeve tube at the stop washer has an outer diameter equal to half of D1, in the transition between the two cone structures has an outer diameter which is larger than the inside diameter d of the tube bead and has an outer diameter at the top smaller than the inside diameter d of the tube bead and greater than or equal to the diameter of the inner passage of the sleeve tube and with four slots in the sides throughout the longitudinal direction of the sleeve tube to the stop washer for compressing the conical sleeve tube.

The joint sleeve is therefore made of a flexible material.

DK 180797 B1 6 The design of the collecting sleeve means that a pipe bead can be easily put on and held repeatedly on the associated collecting sleeve until the pipe bead is removed according to your own needs and that the pipe bead and the inserted sleeve pipe can be easily rotated axially relative to each other.

If the sleeve tube is designed with a circular cross-section, the tube bead is held on the collecting sleeve by virtue of the tube bead being pressed down over the sleeve tube with a light pressure. If the sleeve tube is designed as an inverted truncated cone with slits in the sides, the tube bead is held on the collecting sleeve by virtue of the outward pressure exerted by the sleeve tube on the inner passage of the tube bead when the tube bead is placed on the collecting sleeve and thereby compresses the sleeve tube structure. This force is composed of the frictional resistance of the workpieces, the elasticity of the materials and the design of the sleeve tube. Once the materials are selected, the force can be adjusted by changing the design of the sleeve tube in relation to the width of the slots and the maximum outside diameter of the sleeve tube. At the same time, the compression of the sleeve tube forms the basis for being able to completely fix the pipe bead on the joint sleeve, the inner passage of the sleeve tube being made correspondingly conical as the tube bead is placed on the joint sleeve, whereby the diameter of the sleeve tube compressed opening becomes smaller. By now passing a cylinder with rounded ends through the inner passage of the structure, which cylinder has a diameter smaller than the original diameter of the sleeve tube and is larger than the diameter of the compressed opening, the cylinder will press the side pieces of the sleeve tube in the outward direction and fix the tube bead. on the manifold. Where the sleeve tube on the individual manifold is arranged to form the continuous inner passage in the axial direction of the structure, the stop washer is arranged to hold the tube beads in their position relative to

DK 180797 B1 7 each other, both axially as a separation between two superimposed pipe beads and transversely, where two or more collecting sleeves connected in the stop washers are arranged to hold two or more adjacent pipe beads in place relative to each other and form hereby a manifold module.

According to one embodiment, the manifolds are connected to each other in at least one assembly area on the periphery of the annular stop washer to provide linear or curved manifold modules consisting of a number of connected manifolds.

The joint area is based on the point where two joint sleeves are in direct contact with each other, or for adjacent joint sleeves based on the midpoint between the peripheral points on the line between the center of the stop washers, to provide linear or curved joint sleeve modules consisting of one, two or more rows of continuous joint sleeve, where the joint sleeves in the individual row are of the same size, but that the joint sleeves between the rows may be of different size, which joint outline modules all have the same repeating geometric basic profile for each of the module's external seat sleeves of the stop arc circular arc between two joint areas, which arc will essentially form a semicircle on the longitudinal sides of the module and for end positions the stop arc circular arc may constitute most of a full circle minus the extent of the joint area on the stop arc circular arc.

The joint sleeve modules are typically available in one to three basic patterns for each size of pipe beads.

On one type of coupling module, the coupling sleeves will be at angles of 90 ° to each other with a mutual center distance equal to the diameter D1 of the stop washer in one, two or more parallel rows and where the individual coupling sleeve can be connected to up to four other coupling sleeves .

On another type of coupling sleeve module, the coupling sleeves will be at angles of 60 ° to each other with a center distance equal to the diameter of the stop washer

DK 180797 B1 8 D1 in the form of two or more staggered parallel rows and where the individual joint sleeve in the module can be connected to up to six other joint sleeves.

The third type of joint sleeve module is circular arcs with different radii built around a joint sleeve as the center.

The starting point for the module is thus equal to a hexagon, where the individual joints on the side pieces are evenly distributed on the arch piece between two diagonal points.

All joints on the diagonals will have the center distance D1 and will be in direct contact with each other.

All other joints in the module will have varying center distance to each other depending on where they are located.

Furthermore, there is a joint sleeve module, which is composed of joint sleeves of different sizes, which joint sleeve module will consist of a number of parallel rows, where the joint sleeves are of the same size in each row, but may be cross-connected to a joint sleeve of another size.

The circular shape of the stop washer and their mutual size ratio mean that individual joints must only have direct contact with joints in the same row.

The design of the coupling sleeve modules further means that when all the coupling sleeves in a module are provided with pipe beads on both sides of the stop washer, it will thus essentially only be the outer edge of the stop washer that will be visible between the two rows of pipe beads. long continuous line, while the stop washers and their connecting areas will not be visible from the axial direction of the tube bead, the stop washer and the tube bead both having the diameter D1 and the connecting areas having only a very limited extent which will essentially not be visible when the tube beads are attached.

In the same way, the circular outline of the socket module along the stop washer on the module's outermost row of sockets means that all modules with sockets of the same size on the outside of the module can be brought into direct contact with

DK 180797 B1 9 each other with one or more points of contact on the circular arc of the stop washers and for one or more coupling sleeves along the sides of the modules.

The center distance between the centers of the two tube beads in the individual transition between two modules will thus be equal to D1, as the tube beads will be completely adjacent to each other and it will thus be difficult to determine how many modules have been used for a given structure, how the modules are designed and where the transitions between the different modules are located, two modules with each pattern can be placed in relation to each other so that the pattern in one module can be continued over in the first row of joints in the other module and vice versa or that two modules with the same pattern can be placed so that a different pattern arises than the modules' own pattern in the transition between the two modules.

This also applies to the socket modules where adjustments have been made to the module by removing one or more sockets, as the individual socket can be easily removed from the module simply by cutting the connection areas into the joint between two sockets without changing the module's functionality.

Thus, a single joint sleeve is thus also the smallest size for a module in the system.

Similarly, it is easy to adjust the manifold module with respect to whether or not to remove the vertical pipe sections of the manifold.

This is done by a simple cut.

Movable elements can be established as required in each construction by connecting coupling sleeve modules consisting of a single row of coupling sleeves in such a way that a local vertical pivot point is established on one side and by the coupling sleeve modules lying end to end in the other side.

In addition, the top and bottom must be released.

This is done by not connecting the upper and lower rows of beads in the moving element to the rows of beads before and after.

This can be done either by completely failing to insert a joint in the upper and lower length of the opening, or by removing pipe sections on the part of the joint that can be seen when the structure is open.

The movable element can depending on

DK 180797 B1 10 the construction is otherwise moved at an angle of up to +/- 120 °. If the joint sleeve modules are shortened to consist of only two joint sleeves, the structure will have a pivot point in all joint points in the same way as a bicycle chain and the structure can be folded in relation to the number of joints and moved +/- 180 °. By placing the joints in connection with a displacement of 2 or more beads, the construction will have no pivot point in the construction and can thus not be folded.

According to an exemplary embodiment, the toy building elements comprise a second toy building element - a plate lock arranged to connect at least two joint sleeves of the same size, which plate lock comprises a first gripping claw and a second gripping claw facing in the opposite direction of the first gripping claw, which gripping claws comprise an annular plate with an opening, and that the outer diameter of the annular plate is smaller than the sum of D1 and the wall thickness of the bead, and that the inner diameter is identical to the inner diameter of the associated tube bead.

The plate lock is available in the same way as pipe beads, collecting sleeves and collecting sleeve modules in different sizes. The wall thickness of the pipe bead means the difference between D1 and d divided by two.

The purpose of the plate lock is to assemble assembly sleeve modules consisting of one or more assembly sleeves of the same size for use in the desired motif according to the user's own wishes and needs. The socket modules are connected by means of plate locks placed on the underside of the socket modules. The bead plate is now no longer a predefined size. The manifold modules can now be adapted and assembled into any bottom pattern that can be assembled across the shape and size of the manifold modules so that the spacing ratios of the manifolds can be varied on the entire bead plate. The entire bead plate can thus be completely identical to the motif that is desired to be created.

DK 180797 B1 11 If the plate lock is used in the version where two locks are connected in parallel to each other, the assembly modules will be connected in parallel and the assembly sleeves will be placed at right angles to each other in the assembly. If the lock is cut so that there are more units, these can be placed so that the joints in the joint between two joints modules are displaced at a 60% angle to each other, and the motif can thus change character. If a single plate lock is used as a coupling between two joint socket modules, the modules will have free movement within the limitations that follow from the respective shape of the two modules and the choice of the respective contact points thereon. When connecting modules with joints in a single row, it will thus be possible to turn the connected module +/- 180 degrees in relation to this.

According to an exemplary embodiment, the tube beads and the joint sleeves are dimensioned so that the axial height of the tube bead is equal to the outer diameter D1 of the tube bead minus the thickness of the associated disc sleeve stop disc, and that the outer diameter D1 of the tube bead for the different sizes of single tube beads has double and half size relative to each other in the row of different sizes of tube beads, and that the inner diameter d of the tube bead is substantially equal to but larger than half the outer diameter D1 of the tube bead. The inside diameter d of the smallest tube bead in the system does not have this requirement, which is why d can be dimensioned individually here.

The dimensioning of the axial height of the tube bead thus means that the axial cross section of a single tube bead placed on its stop washer forms a square with the side length D1, whereby a planar structure consisting of tube beads of the same size and with the joints in a parallel structure -pipe beads in length and width will also have a square structure, where the length and width of the structure will be the same and identical regardless of whether the tube beads are upright next to each other or stand in

DK 180797 B1 12 extend on top of each other in the axial direction of the pipe beads, whereby also it applies that a single-pipe bead and its one collecting sleeve within a structure will be able to make room for a transverse single-pipe bead with its axial direction transverse or longitudinal the original structure and partly that two smaller single-tube beads with the half outer diameter of the outer diameter of a larger tube bead coupled to two associated joints in the axial direction of the tube beads will have the same overall height as when the larger single-tube bead is placed on the associated manifold measured from the lower edge of the lower stop washer in the structure to the top of the upper pipe bead in the structure.

This applies regardless of whether the thickness of the stop washer is the same or different for the different sizes of pipe beads, as long as the underside of the stop washers on continuous joint sleeves of different sizes start at the level of each other.

It also follows that tube beads in parallel axial structures, each with its own size of tube bead in the individual axial row of tube beads, can be level with each other at fixed intervals corresponding to the mutual size ratios of the tube beads.

While the dimensioning of the outer and inner diameters of the tube beads means that the inner diameter d of the hole of the larger tube bead matches the outer diameter D1 of the smaller size tube bead in the row so that the smaller tube bead can fit into the inner passage of the larger tube bead, tube beads of different sizes can also be built axially in extension of each other, cf. immediately above.

Consequently, the inside diameter d of the smallest tube bead in the system does not have this consideration, which is why d here can be dimensioned individually.

The tube beads are typically found in the system in one to three dimensioned sizes.

According to an exemplary embodiment, the distance from the stop washer to the opening of the sleeve tube, when the pipe piece is inserted into the inner passage of the tube bead, for larger joints in the system must be equal to the axial height of the tube bead minus half the tube bead outer diameter D1.

DK 180797 B1 13 applies that the pipe section in the inserted condition must not be longer than half of the axial height of the pipe bead. This means that a smaller tube bead with half the outer diameter of a larger tube bead outer diameter D1 will terminate at the level of the larger tube bead when both tube beads are on their respective manifolds and the smaller tube bead is placed down in the inner passage of the larger tube bead, the half diameter of the large bead is equal to the total height of the smaller bead. This is also the basis for the use of differently dimensioned tube beads in the same axial structure going from the smallest and to the largest tube bead and vice versa and that regardless of what size tube bead is started or ended with. According to an exemplary embodiment, the toy building system comprises a third toy building element - a cable guide - which cable guide comprises outer walls whose circumscribed circle has a diameter so that the cable guide fits into the cylindrical passage of the associated tube bead, and comprises continuous passages arranged to guide a string / a cable through.

For the bead sizes where possible, a cable guide can be inserted into the beads in the form of a "cross" having an outside diameter which is slightly larger than the inside diameter of the associated tube bead.

The cable operator has the task of controlling the travel of the traction cables inside the pipe beads so that joint constructions can be activated by means of internal cable traction. The joint function is achieved by placing the cable guide in the pipe bead and trimming the bead and the cable guide at the desired angle from the center of the pipe bead and downwards, so that both are made of a flexible material. The cut in the pipe bead must be perpendicular to the direction of movement of the joint and the cable guide must be rotated 45 ° so that there are two channels on each side of the joint for fixation, as well as a channel inside to close the joint and a channel outside to open the joint. Thus, 4 cables must be installed.

DK 180797 B1 14 By inserting the cable guide and cutting the pipe beads at a given angle, a construction can be provided with movement that can be controlled by means of the internal cable pull. The continuous pipe construction, which occurs when pipe beads are assembled by means of the collecting sleeves, makes it possible to insert cable guides and traction cables, which can give the construction movement in two or more directions or simply strengthen the load-bearing capacity of the construction. According to an exemplary embodiment, the toy building system comprises a fourth toy building element - a zipper - which zipper is cylindrical with an outer diameter adapted to the diameter of the cylindrical passage of the associated pipe bead, and that one end of the zipper comprises a conical top which is adapted to be compressible, which zipper is arranged to be placed in the cylindrical passage of a tube bead.

The stepless unidirectional zipper can be mounted on a stick, string or elastic that can be pulled through the through hole in pipe beads and joints. The zipper can only be moved in one direction, by virtue of its conical design, which is cut through with a vertical cross. The lock has almost the same outside diameter as the inside diameter of the bead.

The use of the zipper makes it possible to cope with opposite loads in the longitudinal direction of the bead construction, by passing, for example, a string through the hole in the beads and tightening up by means of the zipper. The construction will then be able to withstand a load corresponding to the breaking strength of the cord or lock. Since the lock fits the inside diameter of the bead, in some situations the lock may be invisible and in other cases it will be visible on the outside of the construction. According to an exemplary embodiment, the toy building system comprises a fifth toy building element - a double tube bead, which double tube bead consists of two axis-parallel tube beads with the same mutual dimensions connected to each other in a joint area on the outer axis-parallel of the tube beads.

DK 180797 B1 15 wall surfaces. The two tube beads, which form the double tube bead, are connected in a joint area in the same way as the stop washers on the associated joint sleeves. Thus, there are double tube beads for each of the different sizes of tube beads in the toy building system.

The double tube bead must strengthen the structure in the longitudinal direction of the manifold modules, as the placement of double tube beads in the transition between two manifold modules will reduce the vertical distances between contact points in the structure. If a double tube bead is used on each side of the joint, the vertical opening between two adjacent joint sleeve modules will only be equal to the height of the stop washer. This means that the modules will be fixed in relation to each other. If double tube beads are not used, the vertical opening will be equal to the height of the stop disc plus twice the bead height. This can cause the construction to become loose at the top and bottom, unless starting and ending with the socket modules.

The double tube bead will also strengthen the establishment of pivot points in the construction, as this makes it possible to establish fixed support points along the entire length of the pivot point, even if only a single tube bead is included in the pivot point. Similarly, it will be possible to work with multi-joint constructions with only one pipe bead in height, as by virtue of the double pipe bead being placed in the joint it will be possible to have contact points on both sides of the joint construction along the entire length of the construction. The double tube bead can simultaneously connect manifold modules to each other in the same way as the plate lock. If the manifold modules are assembled in extension of each other, the double-tube bead is placed on the manifold at one end of the two modules. If the modules are connected across each other, the double tube bead must be placed on the joint sleeve at the end of one module and placed on an arbitrary joint sleeve on the other module.

According to an exemplary embodiment, at least some of the elements of the toy building system (1) are made of a flexible material.

DK 180797 B1 16 This means that these elements can be easily machined and adapted to the desired shape, size and structure and that the elements can better engage with each other and maintain the formation of the desired structure.

The invention will now be explained in more detail with reference to the figures, in which: FIG. 1A shows the cross section of a first embodiment of a collecting sleeve according to the invention placed in a pipe bead.

DK 180797 B1 18 FIG. 12 A and 12 B show a fifth toy building element - a double tube bead - in cross section axis-parallel to the double tube bead and perpendicular to its longitudinal axis, respectively.

FIG. 1A shows the cross section of a toy building system (1) with a first embodiment of a collecting sleeve (9) according to the invention placed in a pipe bead (6), while fig. 1B shows the cross section of another embodiment of a collecting sleeve (9) according to the invention. The tube beads (6) are hollow bead tubes with an outer diameter D1 and with a continuous cylindrical passage (8) with a diameter d. with a first opening (13) and an opposite second opening (14). About the hollow sleeve tube (11), a projecting and perpendicular to the longitudinal axis of the sleeve tube (11) is an annular stop disc (15) with an outer diameter corresponding to the outer diameter D1 of the connected tube bead (6). This is clearly seen from Figure 1.A, where the cross section of the pipe bead and the collecting sleeve are in direct extension of each other. The joint sleeve (9) is seen in two different embodiments, where fig. 1A shows that the wall (12) of the collecting sleeve (9) is a cylindrical tube comprising two cylindrical pieces of pipe (18, 18) extending externally from this side of the stop washer (15), while fig. 1B shows a second embodiment in which the wall (12) of the collecting sleeve (9) diverges from the annular stop washer (15) and towards the first (13) opening and the second (14) opening, respectively, for providing two conical pipe pieces (18, 18). . The distance of the stop washer (15) to the first (13) and second (14) openings is the same and must be inserted into the inner passage of the pipe bead not more than half of the axial height of the pipe bead so that two joint sleeves can be inserted from each side in the same pipe beads to formation of a continuous structure with a continuous internal axial passage. This is clearly seen in fig. 8 and 9, where structures with resp. six and five layers in the axial direction.

Conveniently, four slots (17) are arranged in the pipe sections (18 °, 18 ”) for compressing the sleeve pipe. The cross section in fig. 1.B thus goes down the middle

DK 180797 B1 19 through the two of the slots, while the third slot (17) can be seen as indicated.

In Figure 3.B, the four slots in the sleeve tube can be seen axially.

FIG. 2 shows an exploded drawing of pipe beads (6) and collecting sleeves (9) for providing a structure in the axial direction of the pipe beads (10), and where collecting sleeves (9) and the corresponding pipe beads (6) comprise different dimensions and where each set (34 , 35) of the smaller tube beads (6) and their joint sleeve (9) fit into the respective larger sets (35,36) of tube beads (6) and their joint sleeve (9) and end at the level of each other.

This is because the tube beads (6) and the coupling sleeves (9) assume different dimensions between each other and the coupling sleeves (9) matched with each other so that the axial height of the tube bead (6) is equal to the outer diameter D1 of the tube bead minus the thickness of the stop washer. (15), and that the outer diameter D1 of the tube bead (6) for the different sizes of tube beads has double resp. half size relative to each other in the row of different sizes of tube beads (6), and that the inner diameter d of the tube bead is substantially equal to but larger than half of the outer diameter D1 of the tube bead. And that the distance from the stop washer to the opening of the sleeve tube, when the sleeve tube is inserted in the inner passage of the tube bead, must be equal to the axial height of the tube bead minus half of the outer diameter D1 of the tube bead for larger collecting sleeves in the system. The inner diameter d of the smallest pipe bead in the system does not have this requirement, so d here can be dimensioned individually just as it applies to the smallest joint sleeve in the system that the sleeve pipe in inserted condition must not be longer than half the axial height of the pipe bead.

FIG. 3A and 3B show linear joint sleeve modules (20), each consisting of two contiguous rows of joint sleeves (9) of the same size.

The manifolds (9) are connected to each other in assembly areas (19) on the periphery of the annular stop washer (15) to provide the linear manifold modules (20) consisting of a plurality of connected manifolds (9). IN

DK 180797 B1 20 fig. 3A, the two rows are offset so that the three joint sleeves are in direct contact with each other and thereby form angles of 60 degrees relative to each other, while the modules in fig. 3B are arranged parallel to each other and thereby form angles of 90 degrees.

FIG. 3 C shows 3 curved manifold modules (20) with different bending radii and a single circular manifold module (20). The latter is similar in structure to Fig.3A. and thereby forms the diagonals of the structure, where the stop washers of the joint sleeves are in direct contact with each other and have the center distance D1. This thus does not apply to the other joint sleeves in the circular arcs, which due to the geometry only have an indirect connection to each other via the joint areas, since their center distance is greater than D1. It is clear from the figures that the different joint sleeve modules all have the same geometric outline predominantly in the form of semicircles and that the joint sleeves (9) can be easily cut off in the joint areas (19), so that a joint sleeve module (20) arises in the desired length and shape.

The smallest unit is thus a single joint sleeve (9). FIG. 4 shows a joint sleeve module (20) composed of joint sleeves (9) of different sizes here three different in 4 rows so that all combinations of the three sizes are available.

The stop washers (15) here have the same thickness for all sizes of joints (9). If the stop washers (15) are to have different thicknesses, the dimension of the thinnest stop washer (15) must follow the joint area (19), otherwise the joint area (19) will shade the smallest tube bead (6). FIG. 5A and 5B show the plate locks (21) of the toy building system (1) whereby the collecting sleeve modules (20) can be connected to each other according to their own wishes and needs. using plate locks (21). Fig. 5A shows a single plate lock (21) arranged to connect two joint sleeves (9) to each other.

FIG. 5B shows a double plate lock (21) which can connect four coupling sleeves (9). Plate lock (21)

DK 180797 B1 21 comprises a first gripping claw 22 and a second 23 gripping claw facing in the opposite direction of the first gripping claw 22. The gripping claws 22,23 are made of an annular plate with an opening 25. The outer diameter of the annular plate is smaller than the sum of D1 and the wall thickness of the bead, and that the inner diameter is identical to the inner diameter d of the associated pipe bead (6), whereby the plate lock (21) can grip the socket pipe sleeve and the smaller pipe bead which matches the inner passage of the beaded bead. Thus, there are also several differently dimensioned plate locks (21) in a toy building system 1 according to the invention.

FIG. 6 A and B show assembly sleeve modules (20) before and after they are assembled into an assembled structure using the plate lock (21). Fig. 6A shows differently shaped and sizes of manifold modules (20) before assembly. The three vertically moving joint sleeve modules 20 on the left side of the drawing and the first joint sleeve in the horizontal section are all the same size and are assembled by fitting directly into the handles on the plate locks 21. The same applies to the joint sleeves assembled by the smaller plate lock 21 to the right of the drawing. Here the dimension is just correspondingly smaller. The other joints in the horizontally extending part of the construction are made by building joint modules 20 of different sizes into each other by virtue of smaller dimensions of beads having twice as many layers of pipe bead (6) in each layer in relation to the larger gem (6). Furthermore, the module on the left shows how attached pipe beads cover stop washers and joint areas, as pipe beads are attached to the lower joint sleeves of the module.

FIG. 6B shows the engagement of the plate locks 21 in the manifold modules 20 for holding them in a desired geometry. The plate locks 21 are mounted on the underside of the stop washer 15 on the respective manifolds 9. By comparing the two situations, it is clear to see how the geometry of the modules fits into each other and thus makes it difficult to determine where one module ends and the other module begins.

DK 180797 B1 22 Fig. 7 is an extension of Fig. 2 and shows an exploded vertical and horizontal construction of a structure by means of differently dimensioned joint sleeve modules 20 and associated pipe beads 6. Also, single joint sleeves 9 are used in the construction. The construction takes place in the axial direction of the pipe beads 6 At two of the manifold modules 20, one or more pipe ends are cut off. This makes room for the collecting sleeve module to be placed on top of the underlying row of pipe beads, as these pipe pieces are located above the horizontal joint of the pipe beads and thereby cannot fit into the underlying pipe bead. The other downward pipe pieces can now be attached to the pipe beads which are located in the inner passages of the bead row (8). FIG. 8A shows two identical wall elements (24) each made up of six joint sleeve modules with five joint sleeves in each module and with associated pipe beads. By assembling the upper five joint socket modules in the wall element (24) in connection, it is achieved that two joint sleeves protrude from one end of the wall element and that a corresponding number of joint sleeves in the same row is missing at the other end. By removing the exposed pipe pieces on the collecting sleeves at the ends of the wall elements, the two wall elements can now be brought together, the ends fitting the same two and two. A pin (37) is placed down through the inner passage of the socket pipe sleeve in the area where the two walls go | engagement with each other as shown in fig. 8 B. and thereby forms a common focal point for the two wall elements, which can be seen from the fact that the two wall elements are now at an angle to each other after assembly. FIG. 9 shows another wall element 24 built up of pipe beads 6, three collecting sleeve modules 20 with five collecting sleeves 9 in each, one of which has had the middle pipe section removed on one side. In addition, it consists of two coupling sleeve modules 20 with two coupling sleeves 9 and associated pipe beads

6. By assembling the assembly sleeve modules 20, as shown in the drawing,

DK 180797 B1 23 a square window 38 with a height and width equal to D1 arises. The window 38 thereby provides space for a transverse row of beads perpendicular to the longitudinal axis of the tube beads in the wall element 24. These can either be assembled by single joint sleeves axially in the longitudinal direction of the tube beads and can thereby be rotated 360 degrees about themselves. Or they can be assembled horizontally so that the pipe beads sit along a single-row joint sleeve module and are inserted sideways into the window. The bead row will then be fixed at 90 degree angles. The structure also shows that the stop washer and the joint areas, which are visible between the different rows of pipe beads, appear as a straight line.

Fig. 10 A shows a third toy building element - a cable guide 26. This is shaped like a cross, the outer walls 27 of which in a circumscribed circle have a diameter so that the cable guide 26 fits into the inner diameter of the associated pipe bead by a clamping fit. Passages 28 thereby arise between the walls of the pipe bead 6 and the walls 27 of the cable guide so that a cord / cable 39 can be passed through. FIG. 10B shows a cross section of the cable guide 26 in fig. 10A arranged in a tube bead 6, and wherein 4 cables 39 are arranged between the outer walls 27 of the cable guide and the walls of the tube bead 6. Fig. 10 C shows the relationship between 2 cable guides 26 and a pair of pipe beads 6, where these are cut off at 45 ° from the center of the pipe bead 6. The cable guides 26 are cut off in the same way. FIG 10 D shows the cable guides 26 and the tube beads bent at 90 ° using the cable pull. Figs. 11 A and B show a fourth toy building element - a zipper 29 - The zipper 29 is cylindrical with an outer diameter corresponding to the outer diameter D1 of a smaller tube bead. The smaller tube bead determines the diameter of the cylindrical passage 8 of the tube bead 6 into which the zipper 29 fits. One end of the zipper 29 comprises a conical top 32 which is adapted to be compressible, there being slits 33 which enable compression. The zipper 29 is arranged to be placed in the cylindrical passage 8 of a pipe bead 6 in extension of the inserted joint sleeve.

DK 180797 B1 24 It is placed with the tip facing opposite to the direction desired to be locked. The slits 33 are pressed together by the surrounding pipe bead 6, so that the lock 29 will be stuck inside the passage 8 of the bead in extension of the opposite pipe socket pipe.

FIG. 12A and 12B show a cross section of a fifth toy building element - a double tube bead (40) - axis-parallel to the double tube bead (40) and perpendicular to its longitudinal axis with the center distance D1 in its entire axial direction. The double tube bead (40) consists of two axis-parallel tube beads (6) having the same dimensions, i.e. same diameter of the cylindrical passage (8), same height, same wall thickness. The tube beads (6) are assembled in a joint area (40) on the outside of the outer wall surfaces (42) of the tube beads, preferably along the entire height of the tube beads (6) to provide a double tube bead (40). If the double tube bead (40) is used in the construction of FIG. 8A, it must replace all the exposed beads at the ends as well as their adjacent bead towards the wall element. This will not change anything about the properties of the wall elements in relation to being able to be connected, and it will still be possible to go from Fig.8A to 8B.

If the double tube bead (40) is used in an assembled construction as Fig. 8B, the double tube beads (40) around the pivot point should now only replace the tube beads (6) on the ends of the joint sleeve modules (20) which are in line with each other. In this way, the two wall elements (24) can continue to be rotated about a local permanent pivot point, but are now built into each other for an overall construction. The double tube beads (40) at the ends of the structure will still need to be placed as described in Fig. 8A.
