Description

[0001] The present invention relates to a constructive kit.

[0002] Magnetic construction kits are widely known, consisting of rods with permanent magnets at their ends and steel balls. By arranging the rods and steel balls in a row, two-dimensional, three-dimensional, or net-like figures can be formed.

The plastic coating tightly overlaps the iron core strip around its circumference, with one end of the iron ball and the iron core strip being fixed as a single unit, and the other end of the iron core strip being provided with a magnetic piece that is also fixed by an inseparable cover in the plastic coating.

[0004] Document CN 2 08 161 048 U discloses an inseparable toy with magnetic rods, consisting of a spherical body, a connecting rod, a casing, and a magnet, wherein the mounting bore of the central axis is arranged through the center of the spherical body on the spherical body, one end of the connecting rod is positively fitted into the mounting bore of the spherical body, and the other end of the connecting rod is tightly enclosed and provided with the magnet, wherein the casing is open at one end and closed at the other end, wherein the blind end of the casing is provided with a circular recess that coincides with the outer wall of the sphere hole, the outer cover is located on the connecting rod, and the blind end of the casing overlaps the magnet at the tip of the connecting rod, wherein the sphere hole is an iron sphere.

[0005] The publication DE 602 06 475 T2 discloses a connection system intended for use in an arrangement of modules with magnetic anchoring of the construction made of stable grid structures, which are used in the field of games, but also in the field of display devices or furniture.

[0006] German patent application DE 10 2012 004 524 A1 discloses a kit comprising a base body (10) with several chambers (12d, 14d) and an element held in the chambers so that it can move freely within them. A coupling unit, i.e., a rod, is arranged with a further element, the elements being designed as permanent magnets (20) such that the elements are magnetically attracted to one another. The base body comprises base body parts (12, 14) that are detachably or permanently connected to one another, one of the body parts being made of a magnetically attracted material or a non-magnetic material. The base body is in the form of a sphere or part of a sphere and has a specific shape selected from a group consisting of a cylindrical shape, a conical shape, a cubic shape, a hexagonal shape, a pyramidal shape, or other geometric shapes.The basic body consists of plastic, wood, cardboard or a non-magnetic metal material.

[0007] Publication KR 10 2010 0 086 917 A discloses a modeling tool comprising a frame assembly forming a magnetic block and a frame for mounting the magnetic block. The frame assembly includes the following: a central sphere (22); a pair of vertical rotating rings (24) with a connecting screw bushing (241) attached to the outer circumferential surface of the central sphere; and a pair of horizontal rotating rings (26) with another connecting screw bushing (261); a ball joint (20) encompassing the rotating rings; a circular head unit (32); a connecting screw (321) screwed into the screw bushings; an articulated arm (30) formed with a connecting unit (34) on one side of the head unit; and an elastic pressure unit inserted between the head unit, the ball joint, and the articulated arm.

[0008] The invention is based on the objective of creating a constructive building kit that, with simple assembly, enables the construction of a wide variety of geometric shapes. Furthermore, the kit should provide a structure that, for a given strength of the permanent magnets, allows for a more robust connection than is the case with known kits. Another objective is to design the kit in such a way that the individual parts cannot be swallowed by small children, which is a problem, for example, with known kits due to the use of relatively small steel balls.

[0009] According to the invention, these problems are solved by a device according to claim 1. Further embodiments of the invention are described in the respective dependent claims.

[0010] The constructive assembly comprises at least one base body formed from at least two ring bands made of a flat ferromagnetic material, wherein a first ring band intersects a second ring band of the at least two ring bands at a first angle at at least one first and one second intersection point, and wherein the first and the second ring bands are rigidly connected to each other at the at least two intersection points. Furthermore, the assembly according to the invention comprises at least one first coupling element, which has at least one permanent magnet at a first end of the coupling element, wherein the coupling element is designed such that it can be magnetically coupled to one of the at least two ring bands via the permanent magnet of the coupling element.

[0011] One advantage of this arrangement is that the base body can be made large enough to prevent accidental swallowing. Furthermore, the use of a flat ring band made of a magnetic material means that the connection between the magnet of the coupling element and the ring band is not limited to a single connection point, as is the case with known kits using spheres and flat magnets. Instead, a continuous line of connection is formed between the flat ring band and the magnet of the coupling element. This allows for a greater force to be achieved between the base body and the coupling element with the same magnetic strength.

[0012] In a further embodiment, the base body can have at least one third ring band made of a flat ferromagnetic material, wherein the third ring band intersects the first ring band at a second angle at a third and fourth intersection point, and intersects the second ring band at a third angle at a fifth and sixth intersection point, and wherein the at least three ring bands are each firmly connected to each other at the corresponding intersection points.

[0013] Such a third ring band increases the stability of the base body and also increases the possibilities for coupling further base bodies.

[0014] Preferably, the first, second and third angles between the ring bands each form a 90° angle, which facilitates the manufacture of the base bodies.

[0015] In a further embodiment, at least one of the ring bands has an opening suitable for receiving a second end of the first coupling part, wherein the first coupling part further has a locking device at its second end which locks in the opening of one of the ring bands.

[0016] This also ensures that a coupling element, for example in the form of a rod, cannot be accidentally swallowed, as it can be securely connected to the base body via the locking device. Preferably, the locking device can have leaf springs that engage in the opening of one of the ring bands. This has the advantage of creating a secure yet detachable connection between the base body and the coupling element.

[0017] In a preferred embodiment, the first coupling part can also have a permanent magnet at a second end, which allows for a high degree of flexibility in the design of bodies.

[0018] Furthermore, a second coupling element can be provided in the form of a V-shaped body with two legs, wherein the V-shaped body has permanent magnets at each junction of the two legs and at the ends of the legs, which can be magnetically coupled to the ring bands. The first and second coupling elements can be used alternatively or together to connect different base bodies.

[0019] Furthermore, a third coupling element can be provided as a body with at least three legs, wherein the body has permanent magnets at each connection point of the at least three legs and at the ends of the legs. The at least three legs can assume any acute angle to each other. Here too, the third body element can be used both as an alternative to the other coupling elements and in combination with them in order to achieve the greatest possible variety of different combinations.

[0020] In a further embodiment, a fourth coupling part can have a locking device at a first and a second end, which locks into the opening of one of the ring bands. This further minimizes the risk of accidental ingestion.

[0021] As mentioned above, at least two basic bodies can be provided which are magnetically or mechanically connected to each other with at least one of the first, second, third or fourth coupling part in order to provide a large number of different combinations and connection possibilities.

[0023] Fig. Figure 1 shows a base body 10 which has the shape of a sphere and in this embodiment consists of a first ring band 12, a second ring band 14 and a third ring band 16, wherein the ring bands each cross at an angle of 90° and are firmly connected to each other at intersection points 12a, 12b, 14a, 14b, 16a, 16b, for example by gluing, spot welding or another common joining method.

[0024] The ring bands 12-16 are formed from a flat ferromagnetic material, for example, a ferromagnetic metal sheet. The ring bands 12-16 have openings 18 in some sections, which allow the receipt of coupling components described in more detail below. As the Fig. As can be seen from Figures 1 and 2A-2C, not all ring bands 12-16 necessarily have such openings. Furthermore, the ring bands 12-16 do not necessarily have to be at an angle of 90° to each other, as shown in Figures 1 and 2A-2C. Fig. 1 is shown, but they can form any suitable angle between 0° and 90°.

[0025] Fig. Figure 3A shows a permanent magnet 19 which is inserted into one of the coupling parts described below and fixed therein by means of a common joining method, preferably by gluing.

[0026] The in Fig. The rod-shaped coupling part 20 shown in Figure 3B has a locking device 21 at one end 20a of the coupling part 20. The locking device can, for example, be, as shown in Fig. Figure 3B shows leaf springs 21a which unfold after being inserted into one of the openings 18 of the ring bands 12-16 and thereby prevent accidental removal of the coupling part 20.

[0027] In Fig. Figure 3C shows a rod-shaped coupling part 22, which has a locking device 21 at each of its two ends 22a and 22b.

[0028] Fig. 3D shows a rod-shaped coupling part 24 in which a permanent magnet 19 is inserted at a first end 24a and a locking device 21 is provided at a second end 24b.

[0029] In Fig. Figure 3E shows a V-shaped coupling element 26 with two legs 26a and 26b, which is intended to show the outer shape of the coupling element 26 without the inserted permanent magnets 19. These permanent magnets 19 are then in Fig. 3F, inserted into the V-shaped coupling part 26, both at a connection point 26c, and in the legs 26a and 26b, shown as dashed lines. The angle between the two legs 26a and 26b is typically between 10° and 170°, but preferably an acute angle.

[0030] The coupling parts and / or legs of the coupling parts described in the preceding paragraphs generally have a circular cross-section. In modified embodiments, these can have a different cross-section and can, for example, have a square, rectangular, hexagonal, or octagonal cross-section.

[0031] Fig. Figure 4 shows a constructive kit 100, which is formed from a multitude of basic bodies 10 and a multitude of coupling parts 22 and coupling elements 26. As the Fig. As can be seen from Figure 4, various connections exist between the base bodies 10, formed by coupling elements 22 and 26. Connections between the base bodies 10 can also be established using coupling elements that have a permanent magnet at both ends.

[0032] Fig. Figure 5 shows a constructive kit 200, which is formed from a multitude of basic bodies 10 and a multitude of coupling parts 24. As the Fig.As can be seen from Figure 4, various connections exist between the base bodies 10, wherein the coupling parts 24 couple to the other base bodies at their first end 24a by means of the permanent magnet 19 and are firmly connected to one of the base bodies 10 at their second end 24b by means of the locking device 22. In principle, however, any corresponding coupling part 20, 22, 24 and 26 can be attached to any of the base elements 10, either purely mechanically by means of the provided locking device or via a magnetic connection using the incorporated permanent magnets 19.
