Abstract

The present invention relates to a construction system comprising construction elements (12) which allow unlimited configurations of structures that can be produced. If the construction system is provided as a toy, the construction elements (12) can be used without undergoing fatigue. The producible structures have sufficient elasticity and can therefore be used, e.g. as a ball. Finally, the construction elements (12) can be manufactured in a simple and cost-effective manner.

Description

construction system

The present invention relates to a construction system according to the preamble of claim 1.

Construction systems are nowadays manufactured and used in a variety of ways. Thus, numerous construction systems are known with which furniture or

Furnishings, for example in the form of room dividers can be generated. By carrying out the design systems with numerous design elements, these objects can be scaled largely arbitrarily.

Above all, construction systems are known from the field of toys. For example, there are plug-in modules which, however, are not directly surface-coupled. In addition, the geometries are limited.

To improve systems have been proposed that are not rectangular. For example, DE 696 30 711 T2 describes a construction system comprising a structural member having a ball connector and an associated socket connector and a body part disposed therebetween. The socket connector can be arranged directly on the ball connector or on the body part. In addition, two or more socket connectors can be coupled together. As a result, it is not only possible to generate planar but complex spatial structures. However, structures created with them always look very much like rod systems.

From DE 10 2009 003 602 A2, a construction system is known, in which the construction elements are formed flat with three corner regions which have coupling elements for identical construction elements. These construction elements are elastic. As a result, surface and spatial structures can be generated. Al lerdings the coupling is relatively susceptible ig, as they can easily solve or break during recording. In addition, the couplings tire after a large number of coupling processes. It is also known from GB 797 877 A already a construction system in which each rectangular Konstruktionsel ement has two diagonally opposite berl constricting butt ends and two diagonally gegenüberl constricting mother ends. The ends of the father are as pins ausge e forms, which have a thickening. The nut ends, in turn, have a corresponding constriction, which has a smaller inner diameter than the thickenings. As a result, the ends of the father can be clipped into the nut ends. Thus, although the connected structural members may be twisted against each other and also some bending stress is withstood by them, the coupling will be released at greater applied energies, such as playing a formed ball against a wall.

The durability of Koppl ments while maintaining the elasticity can be improved if the elements are flat and the coupling is carried out by entangled I neinandersteckcken M utter- and father ends, as it shows the European design 001625575 ¬. The construction element is there formed from an elastic plastic, wherein the nested connectors are formed bent, each with two slits. Since the mother end has the key inside and the father has the key outside and the width of the key corresponds to the width of the thickness of the structural member. The disadvantage of this is that the thickness of the structural elements is limited and the structural elements fatigue at the positions of the slots, since there bending stresses act.

It is therefore an object of the present invention to provide an improved interlocking construction system of the connectors. In particular, un limited configurations of producible structures should be possible. Preferably, the structures produced should be largely free from fatigue, without the obstruction of the coupling between individual structural elements. Preferably, the structures produced should also have sufficient elasticity and, for example, be used as a ball. It is also desirable that the construction elements are easy and inexpensive to manufacture. This task will be solved with the construction system according to the invention according to claim 1. Advantageous further developments are specified in the dependent claims un d in the fol lowing descrip tion together with the figures.

It has been recognized by the inventor that this task can be solved particularly easily in a surprising manner if a pivoting of the second connector along its longitudinal extent is required for coupling, because then the connectors are largely de-energized in the coupled state, as a result of which fatigue the constructional elements are avoided and the construction system is left recordable for a longer time. However, this embodiment of the invention can be used advantageously not only for games, but also for any other applications of construction systems.

The connectors are thus coupling elements which are entangled with each other in the coupled state. Since there always exist at least one connector on a construction s element and a mating connector on the other construction element, which together can form the entangled Koppl ung. The connector can be constructed geometrically different than the mating connector, but it is also possible that both connectors are geometrically identical.

The construction system according to the invention comprising a first construction element and a second construction element, wherein the first construction element comprises a first connector, wherein the first connector has a first longitudinal extent and has a burr, and the second construction element has a second Verbi n, where in the second connector has a second longitudinal extent, and the second connector of the second structural element with its longitudinal extension in the opening of the first connector of the first structural element can be inserted, wherein a Koppl ung of the first construc onselements with the second construct i onselement after a pivoting of second connector to the first connector after insertion of the second connector results in the break, is characterized in that the first connector and the second connector are so ausgebi det that a Koppl ung of ers th construction element with the second construction element only after a pivoting of the second connector along its longitudinal axis gegenüberü on the first connector results. "Crossed pluggable" means in the present invention that the first connector has a through-hole into which the second connector is inserted, with the coupling of the two connections only being completed by the second connector being opposite to the second connector first connector is pivoted after its introduction into the first connector.

In the example of the European design 001625575, the father end is inserted into the nut end, and only by pivoting about the longitudinal extension of the end of the father are the corresponding slots i neinanderteckt, whereby the coupling takes place. Since the construction elements can not be aligned in parallel without the connectors building up restoring forces that introduce bending stresses into the construction system, resulting in fatigue. On the other hand, DE 696 30 711 T2 and DE 10 2009 003 602 A2 show pure clip connections in which no pivoting is possible (DE 10 2009 003 602 A2) or pivoting does not cause a coupling, but only a turning of the connectors against each other (DE 696 30 711 T2). Even with the G B 797 877 A there is a pure clip connection, where the coupling takes place by plugging. A possible pivoting, however, does not cause the coupling.

In contrast, according to the present invention, provision is made for pivoting along the longitudinal extension of the father end. There is thus a change in the inclination of the longitudinal extents of the first connector and the second connector to each other. Since this is a relative panning, d. H. it is possible to change both the inclination of the longitudinal extension of the first connector to the longitudinal extent of the second connector, as well as the inclination of the longitudinal extent of the second connector to the longitudinal extension of the first connector to be changed, as well as the inclination of both the longitudinal extent of the first connector and the longitudinal extent of the first connector second verbs to be changed.

In an advantageous embodiment, it is provided that the second connector can be inserted into the first connector in such a way that a plane in which the first longitudinal extent is located and a plane in which the second longitudinal extent is located are parallel to each other. Preferably, these two E benen identical E benen. If through called in the connected state of the connector, the joints with their Längserstrecku conditions at least in paral lel planes lie, bending stress when playing vermi e be the, whereby fatigue of the Konstruktio nselemente is avoided and the construction system longer recordable bar blei bt.

In an advantageous embodiment, it is provided that the through-opening has an opening which extends along the longitudinal extent of the first connector. Then coupled construction elements are very flat and arranged in an E bar bar.

In an advantageous embodiment, it is provided that the through-opening has an opening which has a shape from the group polygon, circle, rectangle and square. These forms are particularly fatigue educable bar. Advantageously, the edges of the refractions can still be made chastised.

In an advantageous embodiment, it is provided that at least one construction element is designed to be bendable and / or elastic. As a result, it is possible to produce special structures which, if appropriate, also have elasticity, so that, for example, spherical structures such as bearings can be recorded.

In an advantageous embodiment, it is provided that the second connector is arranged transversely to the first longitudinal extent in the first connector bar bar. Then you can make a variety of different geometrically constructed figures. In this case, the longitudinal extents of the two verb indians in the connected state of Verbi n of forcibly in an identical plane.

In an advantageous embodiment, it is provided that the second connector can be arranged in the first connector in a form-locking and / or frictionally engaged manner in the first connector. Then the finished structures are designed to be particularly durable.

In an advantageous embodiment, it is provided that the first construction element and / or the second construction element have a body part with a third longitudinal extent on which the first or the second connector is arranged, wherein the third longitudinal extent preferably does not coincide with the first or the second Longitudinal extension is. As a result, it is possible to produce structures in which there is no height offset between the construction elements.

In an advantageous embodiment, it is provided that the first and / or the second construction element have at least one first and one second connector, preferably at least two first and two second connectors. Then you can create arbitrarily dimensioned structures.

In an advantageous embodiment, it is provided that the first and / or the second construction element have a plurality of first and / or second connectors, the first and second longitudinal extensions of which lie in one plane. Then, construction elements thus incorporated lie in a plane of a generated structure.

In an advantageous development is provided that the first construction element and the second construction element are identical. Then the constructional system is particularly simple.

In an advantageous development is provided that the first connector is at least partially annular. Then the structures produced are particularly favorable, with a high durability and at the same time the least possible expenditure of material. In addition, in this connector of the corresponding mating connector can be rotated about the axis of rotation of the annulus, so that any geometrical Struktu ren can be generated.

In an advantageous embodiment, it is provided that the second connector has a connecting element, which is preferably formed at least partially round-shaped, wherein the connector element in particular at least on one side at least partially a rounded is formed. This also makes a particularly high durability of the structures produced sichergestel lt. In addition, this connector can be rotated in its mating connector about the axis of rotation of the Rond e, so that any geometric structures can be generated. "Rondenförmig" means in this

Connection cylindrical in shape with a smaller height relative to the diameter. In an advantageous embodiment, it is provided that the second connector has a first stop, which is designed to be plug-in by the first connector and, in the connected state of the first and second connector, removal of the second connector from the first connector perpendicular to the longitudinal extent of the second Verbi prevents where it is preferred in the first stop as at least partially Auskr agen tion over the connector element is formed, which protrudes in particular along the longitudinal extent of the second connector against a connector element of the second connector. As a result, a self-contained decoupling of the connector is prevented even if the construction elements are under tension, for example in the case of curved spatial structures.

Alternatively or additionally, it is advantageous if the second connector has a first stop, the point at the coupling of the first connector and the second connector as a lever and / or joint of the pivoting can act. As a result, the coupling is particularly easy.

In an advantageous embodiment, it is provided that the second connector has a second stop, which prevents the second connector from slipping through the first connector during insertion, the second stop being preferably used as a shoulder on the body part and / or on the connector element is formed, in particular, has a larger cross-section than the through-opening of the first connector. As a result, the construction of the desired structure from the construction elements is substantially facilitated. In addition, the couplings of the constructional elements can thus not change during recording, so that it is not possible to push through the one connector through the mating connector.

Alternatively or additionally, it is advantageous if the second connector has a second stop which can act on the coupling n and / or decoupling n of the first connector and the second connector as a lever point and / or joint of the pivoting. This makes the Koppl ung or Entkoppl ung particularly easy.

In an advantageous embodiment, it is provided that the first connector and the second connector are adapted to each other verbun by a plug-tilting movement. and a tilt-pull movement to be solved by each other. Then the ge wished structures are particularly easy to produce and disassembled. The tilting movement preferably takes place transversely to the longitudinal extent of the connector to be tilted.

FIGS. 1 to 7 show a first preferred embodiment of the inventive co-design system 10 in various views.

It can be seen that the construction system 10 has identically designed construction elements 12, each having a central body portion 14 and verbi n disposed thereon 16, 18, which are arranged so that they the construction element 12 in plan view (see. Fig. 3 and 4) give approximately the shape of a rectangle. Since, however, recesses 20, 22 are provided, whereby the construction element 12 acts slimmer in the plan view and also the backlash is increased.

It can further be seen that the first connector 16 is partially annular and has a circular billing 24 with a chamfered edge 26.

The second connector 18 has a connector element 28, which in some areas is ronde shaped with a bevelled upper edge 30. The chamfer 30 is more pronounced than the chamfer 26, whereby the coupling between the second connector 18 and the first connector 16 can be particularly simple, as will be explained.

In addition, the second connector 18 has a first stop 32, which is designed as a region as a projection and is opposite to the rear edge 33 of the connector element 28 (see FIG. 2). In addition, there is a second stop 34, which is designed as a double-sided shoulder on the body part 14. This stop 34 has a larger cross section than the cross section of the connector element 28. In addition the stop 34 has a larger cross-section than the inner diameter of the through-break 24th

The inner diameter of the recess 24 and the outer diameter of the connecting element 28 are adjusted so that an interference fit and thereby a positive and a force fit is achieved when both connectors 16, 18 are coupled together.

Furthermore, it can be seen that both the first connector 16 and the second connector 18 each have longitudinal extensions L 1, L 2 lying in a common plane E (see FIG. 2). More specifically, the longitudinal extents LI, L2 are each in their own planes, which coincide above in the plane E.

Of this, the plane in which the longitudinal extent L3 of the body part 14 lies lies between them, where the body part 14 is additionally curved. Thus, there is no plane in which the longitudinal extent L3 of the body part 14 lies, which coincides with a plane in which the longitudinal extents LI, L2 lie.

In Fig. 5, a preferred embodiment of a Hergestel with the construction system 10 lten object is shown, which is designed as Bal l 100.

It can be seen here that a total of 30 individual construction elements 12 have been connected to one another so that around an inner 102 of the ball 100 there is an almost spherical outer surface 103 with recesses 104, 106 located therein Above all, this is also possible because the planes of the longitudinal sections LI,

L2, the connector 16, 18 is set back in relation to the plane of the longitudinal extension L3 of the body part 14, so that no such dislocations and jumps result, as they are, for example, in the European design 001625575.

More specifically, the Bal l 100 has two different recesses 104, 106, where in the first Aussparungsart 104 is approximately circular and by Koppl tion of three construction s elements 12 a, 12 a ', 12 a "along their recesses 20 along the respective n Längser extension L3 the body parts 14 is formed. The recesses 106 in turn are approximately star-shaped with five teeth. They are formed by the coupling of five construction elements 12a, 12b, 12c, 12d, 12a "along their recesses 22 perpendicular to the respective longitudinal extent L3 of the body parts 14.

The fact that the body parts 14 are formed bent and by their flexibility, the ball 100 can be easily plugged together and he also has a high resistance s- force against solution of the construction elements 12 from each other and a Flexibil ity when pressure on the ball surface 103. Thus, the Bal l 100 not only produces high speed, but also plays superbly. In other words, throwing the ball 100 against a solid wall (not shown) does not disengage the structural members 12 from each other, but the kinetic energy of the ball 100 upon impact with the wall results in bending of the resilient structural members 12, causing them kinetic energy is stored and released again as part of a relaxation of the bent constructional elements 12, whereby the ball 100 bounces off the wall. This is a significant difference from all known construction elements which are interconnected by a simple vertical clipping where such clipping will result in a solution of the construction elements.

The assembly and separation of the construction elements 12, 12 'is shown in FIGS. 6 and 7 dargestel lt.

It will be appreciated that when assembled, the second connector 18 is simply inserted into the first connector 16. More specifically, the connector element 28 of the second connector 18 is inserted with its first stop 32, which projects along the longitudinal extent L2 of the second connector 18 over the connector element 28 ü, in the first through-opening 24 of the first connector 16. Since at the Längserstrecku n conditions LI and L2 are tilted against each other, for example by 90 °. On the other hand, due to the clear projection of the first abutment 32 relative to the round-shaped connector element 28, a perpendicular insertion of the second connector 18 into the first connector 16 is not possible with parallel longitudinal extensions LI and L2. The second stop 34 of the second connector 18, which has a larger cross-section than the inner diameter of the through-hole 24 is there for abutment on the first connector 16, whereby the second connector 18 through the first verbi n-16 d can not slip through.

The abutment points of the second stops 34 on the top 36 of the first connector 16 then act as a hinge and lever point and the second connector 18 can be tilted about this joint gegenü over the first connector 16 until the first stop 32 on the U nterseite 38 of first connector 16 strikes. The tilting takes place at transversely to the longitudinal extent L2 of the second connector 18. In other words, there is pivoting along the longitudinal extent L2 of the second connector 18.

Since at the rear edge 33 of the connector element 28 and in opposite directions, the chamfer 26 of the connector element 28 is pressed into the opening 24, whereby the first and second connectors 16, 18 form a press fit.

This results in a very secure locking of the connection between the first connector 16 and the second connector 18 by the abutment of the first stop 32 on the bottom 36 of the first connector 16 and the second stop 34 on the top 38 of the first connector 16, whereby the connection, ie the Koppl ung between the first connector 16 and second connector 18 and thus the Koppl ung between the first construction element and the second construction element 12 'is particularly durable.

If, however, the second connector 18 is not inserted so deeply into the first connector 16 that the second stops 34 on the upper side 36 come to rest, then the first stop 32 is brought to bear against the U nterseite 38 of the first connector 16 during tilting , Then this system of the first stop 32 acts on the bottom 38 as a corresponding joint and lever point.

Then, during tilting, in turn, the trailing edge 33 of the connector element 28 is pressed into the aperture 24, whereby first and second connectors 16, 18 form a press fit. Here, too, pivoting takes place along the longitudinal extension L2 of the second connector 18. Disconnecting the connection of the first and second connectors 16, 18 is accomplished by tilting the second connector 18 transversely to the longitudinal extent L2 of the second connector 18 opposite the first connector 16 (pivoting along the longitudinal extent occurs at re rum e rum L2 of the second connector 18). Since acting through the system of the second Ansch läge 34 on the O berseite 36 of the first connector 16 joint again acts as a fulcrum, whereby the rear edge 33 of the connector element 28 and in opposite directions, the chamfer 26 of the connector element 28 pulled out of the opening 24 through and thereby the interference fit is released and finally the second connector 18 can be removed from the first connector 16.

Again, in turn prevents the larger cross-section of the second stop 34 of the second connector 18 with respect to de n I nnendurchmesser the opening 24 through slipping of the second connector 18 through the first connector sixteenth

In addition, the significant protrusion of the first stop 32 against the ronde-shaped second connector 28 prevents perpendicular removal of the second connector 28 from the first connector 18 at paral lel aligned longitudinal extents LI and L2.

Due to the relatively large length of the body part 14 with respect to the distance from the rear edge 33 and bevel 26 from the forming joint, when connecting and disconnecting the construction elements 12, relatively large levers are generated which do not require large forces.

By forming the first connector 16 as a partial annulus and the second connector 18 with a blank-shaped connector element 28, two interconnected construction elements 12 can be pivoted freely about the vertical axis formed by connection of the two connectors 16, 18 (see FIG. and so far until the structural elements along the recesses 20 or the recesses 22 collisions. This free movement is still aided by the recesses 20, 22 and the inclined connection to the first connector 16 to the body part 14. Thereby, two construction elements 12 can be connected to one another not only with one respective connector 16, 18, but also with two adjacent connectors 16, 18, wherein both a connection along the

Recess 20, as well as along the recess 22 mögl I is.

In addition to complex shapes, such as the Bal l 100, in which the construction elements 12 are aligned at an angle to each other, thereby shapes can be generated in which at least some construction elements 12 are parallel to each other z.

In Fig. 6 and 7, only a coupling of the two construction elements 12, 12 'via the coupling of the second connector 18 to the first connector 16 is shown. However, it could also at the same time still a Koppl ung of the second connector 18 'with the first connector 16' exist, so that the two structural elements 12, 12 'along the recesses 22 of the body parts 14 would be connected.

In the construction example 200 shown in Figs. 8a, 8b, 8c, two structural members 12, 12 'are provided by coupling the second connector 18 to the first connector 16 and the second connector 18' to the first connector 16 'along the recesses 20 of the body part 14, 14 ', whereby an opening 202 ergi bt, which is just so large, in the body part 14 "of a third construction element 12" kraftschl üssig, d. H. pinching, picking up. As a result, complex 3-dimensional shapes can be generated because, independently of the construction elements 12, 12 ', further constructional elements 12 can be coupled directly to the construction element 12 ".

In addition, two construction elements 12, 12 'can be coupled directly to each other (not shown), in which case all the first connectors 16, 16' are coupled to the corresponding second connectors 18, 18 '. As a result, the body parts 14, 14 ', which in each case are arched outwards, in turn create an opening in which a third construction element 12'"can be arranged in a force-fitting manner, ie by clamping. Due to the elasticity is also a folding of the construction elements 12 to the

Recesses 20 possible, in which case the first connector 16 with the gegenü berliege n- the second connector 18 of this construction element 12 can be coupled n.

In FIGS. 9 a), b), c) and 10 a), b), c), alternative embodiments for the construction element 210, 212, 214 according to the invention are shown in side views and in perspective views, respectively.

It will be appreciated that these structural members 210, 212, 214 also each include two first connectors 216, 218, 220 and two second connectors 222, 224, 226, which, however, are not arranged in a quadrangle as in the structural member 12 but linearly to a rod-shaped body 228, 230, 232, where at each of the second Verbi n 222, 224, 226 are on the outside and the first connectors 216, 218, 220 disposed therebetween.

These construction elements 210, 212, 214 also have such an elasticity that they are foldable (not shown) in order to couple a second connector 222, 224, 226 to a separate first connector 216, 218, 220.

The construction elements 212, 214 additionally have openings 234, 236 into which other construction elements 12, 210, 212, 214 e can be inserted. When these construction elements 12, 210, 212, 214 have been folded as described, they can be hooked into the openings 234, 236 to form movable branches of complex 3-dimensional constructions.

When coupling between a first structural element 214 and a second structural element 214 (not shown), the second connector 226 of the second structural element 214 could also be inserted through the opening 236 of the first structural element 214 and subsequently connected to the first connector 220 of the first structural element 214 Construction elements 214 are coupled. Figures 11a, 11b show, in perspective and plan views, a construction example 300 with numerous construction elements 212 in a right-angled relationship to one another.

Figures 12, 13 show in perspective and plan views construction examples 400, 500 with numerous construction elements 214 in non-orthogonal arrangements with each other.

In Figs. 14 to 17, the general principle of the invention Koppl 600 of a first connector 602 and a second connector 604 is shown. In each case, the figures a show a perspective view and the figures b each have a side view. These connectors 602, 604 may be disposed on each of the illustrated structural members 10, 210, 212, 214, or other geometrically designed structural members, as first and second connectors.

It can be seen that the first connector 602 is again formed in an annular shape with a circular opening 606. Since the opening 606 extends along the longitudinal extent L of the first connector 602.

The second connector 604 has a connector element 608 which is formed almost voluminously kuge I-shaped. On the connector element 608 are a first abutment 610 in the form of a regional projection and a second abutment 612 in the form of a shoulder on which a body part 614 is arranged. There may not be any other first connector 602 and / or second connector 604 on that body part (not shown).

The first stop 610 has on its underside 616 a circular segment-shaped contour, which is dimensioned so that it can be inserted together with the spherical Verbi nderelement 608 in the circular opening 606 of the first connector (see Fig .. 15). The circular segment-shaped contour thus extends tangentially from the connector element 608.

On the other hand, the second stop 612 projects along the longitudinal extent L 2 d of the second connector 604 with respect to the connector element 608, so that the connector element 608 can be inserted only halfway into the opening 606 of the first connector 602 (see Fig. 15).

After the second stop 612 has come into contact with the first connector 602 (see Fig. 15), the second connector 604 is pivoted relative to the first connector 602, where in the longitudinal extensions L'l, L'2 against each other 15 are tilted from the 90 ° orientation shown in FIG. 15, via an inclined orientation (see FIG

180 ° orientation (see Fig. 17).

During tilting of the second connector 604 relative to the first connector 602, the connector element 608 acts as a pivot about which the aperture 606 rotates. This rotation is stopped in the state shown in FIG. 17 of the parallel alignment of the longitudinal extensions L 1, L'2 of the first connector 602 and the second connector 604 in that on the one hand the back 618 of the first connector 602 on the first stop 610 comes to the plant and on the other hand the front 620 of the first connector 602 comes to rest on the second stop 612.

The decoupling between the first connector 602 and the second connector 604 is simply in the reverse order, ie by tilting (see Fig. 16) to the 90 ° orientation (see Fig. 15) and a removal of the second connector 604 from the first connector 602 (see Fig. 14).

Advantageously, there is a press fit between the opening 606 and the connector element 608.
