Such a toy assembly may comprise a small number of types of toy pieces for constructing the three-dimensional construction assembly. In an example, the toy pieces may comprise rods and connector pieces, wherein a connector and a rod may be connected to each other or connectors may be connected to other connectors.
In an example, the construction toy system comprises a variety of molded plastic connector elements, which are arranged to be joined with rod-like struts elements, to form complex structural units.
The connector element comprises a socket -forming recess for receiving a strut. The socketforming recess comprises a pair of spaced-apart gripping arms. The pair of spaced-aparl gripping arms hold one pair of transversely extending ribs for receiving the strut. The ribs have a cylindrical contour. The transversely extending ribs project into the recess to form a constricted inner throat area within the socket -forming recess.
The strut element comprises end portions, each comprising a flanged portion at the end extremity, an annular groove adjacent thereto and, a cylindrical portion adjacent to the annular groove.
The strut elements are arranged to be inserted into the socket -forming recess of the connector element with the flanged portion at the end extremity being received in the locked section formed by the constricted inner throat area of the recess.
The construction toy system has the disadvantage that the flanged end portion of the strut element can only be connected to the connector element in a single relative position, wherein the angle of the strut element is relatively fixed to the connector element. Furthermore, in order to assemble the connector elements at various angle with respect to each other, an increasing types of connector elements are necessary, each connector type being designed for providing a specific angle.

In particular, each jaws pair may have a pair of jaw elements, a receiving recess, a first pair of capturing protrusions for capturing a second connector and a second pair of capturing protrusions for capturing the second connector, which are substantially identical in size to one another, respectively. Thus supports easy assembling of first connectors with one another.
Alternatively or additionally, the first connector may have a first jaws pair and a second jaws pair, wherein first jaws pair has a size different from a size of the second jaws pair. For example, the first jaws pair may have a pair of jaws element forming a receiving recess and holding both pairs of capturing protrusions at a receiving distance of 8 mm and the second jaws pair may have a pair of jaws element forming a receiving recess and holding both pairs of capturing protrusions al a receiving distance of 20 mm.

Description of embodiments
Figures 1A, IB, 1C and ID show a exemplary embodiment of a first connector piece. Figure 1A shows schematically a perspective view of an embodiment of the first connector 100. In figure 1A the first connector piece 100 has a body 110 extending in a longitudinal axis LI and has two jaws pairs 120, 130 arranged at each end of the body 110 in the longitudinal direction of the longitudinal axis L1.
The first jaws pair 120 comprises a pair of jaw elements comprising a first jaw element
122 and a second jaw element 124 which are facing each other thereby forming a receiving recess for receiving another connector. Both jaw elements 122 and 124 extend along the longitudinal axis of the body 110. In this embodiment, the pair of jaw elements 122, 124 are arranged opposite one another enclosing the longitudinal axis LI of the body 110 thereby forming the receiving recess for receiving another connector. Furthermore, the first jaw element 120 comprises a first, outer, pair of capturing protrusions 128 for capturing a second connector piece and comprises a second, inner, pair of capturing protrusions 126 for capturing the second connector piece.
Figure IB shows a plane view on the first connector piece 110 thereby showing the body 110 the first jaws pair 120 and the second jaws pair 130. As is shown in figure IB the first pair of capturing protrusions 128a and 128b is arranged extending substantially opposite to one another and facing one another along a first axis Pl. The second pair of capturing protrusions 126a and 126b is arranged extending substantially opposite to one another and facing one another along a second axis P2. The first axis Pl and the second axis P2 are arranged substantially perpendicular to the longitudinal axis LI of the body 110 of the first connector piece 100.
The first axis Pl and the second axis P2 are arranged substantially parallel to one another and are arranged offset to one another along the longitudinal axis Ll. The first axis Pl is arranged at an outer end of the first jaws pair 120 and the second axis Pl is arranged at an inner portion of the first jaws pair 12O.The first axis Pl and the second axis P2 are arranged at a predetermined distance between one another along the longitudinal axis Ll.
The capturing protrusions of the first pair of capturing protrusions 128a, 128b and the capturing protrusions of the second pair or capturing protrusions 126a, 126b are shaped substantially as a semisphere. In an example, these capturing protrusions have a radius R of about x. The radius R is also shown in figure 1C which shows one jaws pair 120 or 130 in the plane of the first axis and the second axis Pl and P2 and an orthogonal direction O perpendicular to Pl and P2.
The second jaws pair 130 which is shown in figure 1A and IB also has a pair of jaw elements 132 and 134 which are arranged opposite one another enclosing the longitudinal axis Ll of the body thereby forming a receiving recess for receiving another connector. Furthermore, the second jaws pair 130 also has a first pair of capturing protrusions 136a and 136b and a second pair of capturing protrusions 138a and 138b as is shown for the first jaws pair 120.
Furthermore, the body 110 has two pairs of grooves extending along the longitudinal axis Ll of the body. Both pairs of grooves 112 and 114 are arranged at locations of the peripheral surface of the body 110. A cross section of the body 110 is shown in figure ID, wherein the peripheral surface of the body is shown and a first pair of grooves 112a, 112b and a second pair of grooves 114a, 114b. Each pair is arranged at an opposite side of the peripheral surface of the body 110 of one another. The body 110 has a substantially circular shaped parameter wherein the parameter has a diameter D as shown in figure ID. Each of the grooves 112a, 112b and 114a, 114b has a shape of a V groove wherein the V groove has a span angle a as shown in figure 1C. The angle span a is selected in the range of 85 till 100°.
The grooves pair 112a and 112b extend along the longitudinal axis LI from the receiving recess of the first jaws pair 120 up to the receiving recess of the second jaws pair 130. In this arrangement, a pair of capturing protrusions may easily be introduced into the pair of grooves 112a, 112b by sliding the pair of capturing protrusions from one of the receiving recesses of the first connector 100 along the pair of grooves 112a, 112b up to a desired position along the longitudinal axis of the body LI of the first connector 100.
The first jaws pair 120 further has a blocking element 140 having a first guiding surface arranged adjoining to one groove 112a of the grooves pair 112a, 112b and a second guiding surface arranged adjoining to the other groove 112b. The first and second guiding surfaces are arranged for guiding a pair of capturing protrusions towards the grooves pair 112a and 112b when assembling the first connector and another first connector 100’, for example such as shown in Figures 2A and 2B for a first assembled state and such as is shown in Figures 2C - 2E for a second assembled state.
The blocking element 140 has a blocking surface arranged at a free end of the blocking element 140 along the longitudinal axis at a predetermined distance with respect to the first axis Pl and / or the second axis P2. The blocking surface is arranged at the free end of the blocking element 140 for abutting another connector, which is introduced in the receiving recess of the first jaws pair 120. The second jaws pair 130 also has a blocking element 140 having a first guiding surface, a second guiding surface and a blocking surface arranged in the same way with respect to the grooves pair 112a, 112b and the receiving recess of the second jaws pair 130.
The pair of grooves 112a and 112b are arranged at a side or location of the peripheral surface of the body 110 such that a first connector piece 100 and another connector piece, such as another first connector piece 100, can be assembled in an assembled state wherein the protrusions 126a and 126b, optionally including the protrusions 128a and 128b, can capture the other connector piece 100’, 200 by introducing said one or two pairs of capturing protrusions into the pair of grooves 212a and 212b of the other connector piece 100’, 200. Such an assembled state is shown in figures 2A - 2B and in Figures 3A- 3B, respectively.
Figures 2A and 2B show a first assembled stale of the first connector piece 100 and another first connector piece 100’. Figure 2A illustrates a perspective view and figure 2B shows a plane view on the first connector piece 100 and another first connector piece 100’ in the first assembled state. In the first assembled state the outer pair of capturing protrusions 128of the first jaws pair 120 of the first connector piece 100 is introduced into a pair of grooves 112a’ and 112b’ of the other first connector piece 100’. Additionally, the outer pair of capturing protrusions 128’ of the other first jaws pair 120’of the other first connector piece 100’ is introduced into a pair of grooves 112a and 112b of the first connector piece 100. In this assembled state, the first jaws pair 120 and the other first jaws pair 120’are partly enclosed by each other.
The inner pair of capturing protrusions 126 of the first jaws pair 120 of the first connector piece 100 may be located outside a groove 112a of the other first connector piece 100’, such as being located in a space of the other first jaws pair 120’of the other first connector piece 100’.
Furthermore, the first jaws pair 120 and the other first jaws pair 120’, including the capturing protrusions 128, 128’, are arranged at a twist angle relative to one another about the longitudinal axis LI, such that the first jaws pair 120 and the other first jaws pair 120’ do not block one another in the first assembled state.
In the specific embodiment shown, the first jaws pair 120 and the other first jaws pair 120’ are arranged substantially perpendicular one another, i.e. at about 90 degrees, about the longitudinal axis LI. The corresponding capturing protrusions 128, 128’ including the associated first axis Pl, ΡΓ are arranged at a twist angle of about 90 degrees between one another about the longitudinal axis LI.
In this way, in this assembled state, both first connector pieces 100, 100’ are fixed in a lateral direction (or orthogonal direction O) perpendicular to the first axis Pl, Pl ’ of the other first connector piece 100, 100’and and are fixed in a rotational direction about the first axis Pl and in a rotational direction about the other first axis PF relative to the other first connector 100, 100’, respectively.
Alternatively, the twist angle between the first jaws pair 120 and the other first jaws pair 120’, including the corresponding capturing protrusions 128, 128’, about the longitudinal axis LI may be selected suitably, such as between 30 degrees and 90 degrees, for fixing both first connector pieces 100, 100’ in a lateral direction (or orthogonal direction O) perpendicular to the first axis Pl of the other first connector piece 100, 100’.
Furthermore, a relative position of the first connector pieces 100, 100’ between one another along the longitudinal axis LI is determined by the blocking surface 140, 140’ of each of the connecting jaws pairs 120, 120’by abutting the blocking surfaces 140, 140’against one another along the longitudinal axis L1.
In an alternative embodiment of the first assembled state of the first connector piece 100 and another first connector piece 100’ shown in Figures 2A and 2B, the second, inner, pair of capturing protrusions 126 of the first jaws pair 120 of the first connector 100 may be arranged to be introduced into a pair of grooves 112a’ and 112b’ of the other first connector piece 100’ in the first assembled state, similar to the exemplary embodiment of a first assembled state of the first connector piece 100 and a rod shaped connector piece 200 shown in figures 3A - 3B.
For example, the predetermined distance between the first axis Pl and the second axis P2 may be selected of the first, outer, pair an the second, inner, pair of capturing protrusions 126, 128, respectively, such that both pairs of capturing protrusions 126, 128 of the jaws pair 120 is introduced into the pair of grooves 112a’ and 112b’ of the other first connector piece 100’.
Additionally, the second, inner, pair of capturing protrusions 126’ of the other first jaws pair 120 of the other first connector 100’ may be arranged to be introduced into a pair of grooves 112a and 112b of the first connector piece 100 in the first assembled state, similar to the exemplary embodiment of a first assembled state of the first connector piece 100 and a rod shaped connector piece 200 shown in figures 3 A - 3B.
Figures 3A - 3C show in another exemplary embodiment of a first assembled state of the first connector piece 100 and a rod shaped connector piece 200. Figure 3A illustrates a perspective view in the first assembled state. Figure 3B shows a plane view on the first connector piece 100 and the rod shaped connector piece 200. Figure 3C shows a cross section view on the first connector piece 100 and the rod shaped connector piece 200 along a line C-C shown in Figure 3B.
In the first assembled state both pairs of capturing protrusions 126, 128 of the jaws pair 120 of the first connector piece 100 is introduced into a pair of grooves 212a and 212b of the rod shaped connector piece 200. In this assembled state the rod shaped connector piece 200 is fixed in a lateral direction (or orthogonal direction O) perpendicular to the first axis Pl and / or the second axis P2 of the first connector piece 100 and is fixed in a rotational direction about the first axis Pl and / or about the second axis P2 relative to the first connector 100.
is fixed along a longitudinal axis L2 of the body 210 the rod shaped connector piece 200 relative to the first connector piece 100. Furthermore, a relative position of the first connector pieces 100 and the rod shaped connector piece 200 along the longitudinal axes LI, L2 is determined by the blocking surface 140 of the connecting jaws pairs 120 by abutting the blocking surface 140 against an end surface of the rod shaped connector piece along the longitudinal axis LI inside the receiving recess of the first jaws pair 120.
Figures 2C - 2E shows a second assembled state of the first connector piece 100 and another first connector piece 100. Figure 2C illustrates a perspective view of the second assembled state. Figure 2D shows a plane view on the first connector piece 100 and the first connector piece 100’. Figure 2E shows a cross section view on the first connector piece 100 and the first connector piece 100 along a line B-B shown in Figure 2D.
The one first connector piece 100‘ is fixed in a lateral direction (orthogonal direction O of first connector piece 100‘) by the capturing protrusions 128a, 128b of the first jaws pair 120 of the first connector piece 100 by introducing one pair of capturing protrusions 128a and 128b of the first connector piece 100 into the pair of grooves 112a and 112b of the other first connector piece 100.
In the position of the second assembled state shown in figure 2C the longitudinal axis L2 of the body and of the pair of grooves 112a and 112b of the other first connector piece 100’is arranged substantially perpendicular to the longitudinal axis LI of the first connector piece 100. Additionally, in the second assembled state the other first connector piece 100’ is rotatably mounted onto the first connector piece 100, as indicated by arrow T in figure 2D, about the first axis Pl provided by the first pair of capturing protrusions 128a and 128b of the first jaws pair 120.
Furthermore, the other first connector piece 100’ is moveable along its grooves 112a, 112b along the longitudinal axis L2 with respect to the other first connector piece 100. The second assembled state provides the advantage that the other first connector piece 100’ is moveable along the longitudinal axis L2 and is rotatable along a first axis Pl of the first connector piece 100. This provides freedom in assembling the first connector pieces 100, 100’to one another while having the freedom of selecting a longitudinal position of the capturing protrusions 128a, 128b along the pair of grooves 112a, 112b in the longitudinal direction LI and a rotational position or angle of the other first connector piece 100’in a rotational direction as indicated by arrow T about the first axis Pl of the first connector piece 100.

Additionally, in the second assembled state the rod shaped connector piece 200 is rotatably mounted onto the first connector piece 100, as indicated by arrow T in figure 3E, about the first axis Pl provided by the first pair of capturing protrusions 128a and 128b of the first jaws pair 120.
In the Figure 3D shown, the rod shaped connector piece 200 is captured by the first connector piece 100 at a middle portion of the rod shaped connector piece 200. Alternatively, the rod shaped connector piece 200 may be captured by the first connector piece 100 at an end portion of the rod shaped connector piece 200, i.e. along its longitudinal axis L2. In that position, a rotation range of the rod shaped connector piece 200 about the first axis Pl of the first, outer, pair of capturing protrusions 128a and 128b as indicated by arrow T may be even further enlarged.
Furthermore, the rod shaped connector piece 200 is moveable along its grooves 212a, 212b along the longitudinal axis L2 with respect to the other first connector piece 100.

Figures 8A- 8C show another exemplary embodiment of a second connector piece according to the present invention. Figure 8B shows a perspective view of the rod shaped second connector 800.
Figure 8A shows a plane view on the second connector piece 800 along a first longitudinal axis LI of the body 810 and along a first axis P l of the first pair of capturing protrusions 828.
The rod shaped second connector 800 has a rod shaped body 810 and a jaws pair 820 connected to the body 810.
The body 810 further comprises two pairs of grooves 812, 814 distributed over the peripheral surface of the body 810. Each pair of grooves 812, 814 extends along the longitudinal axis LI. A first pair of grooves 812 is located at a twisting angle of 90 degrees with respect to the second pair of grooves 814 about the longitudinal axis LI. Each pair of grooves 812, 814 extends up to an end of the second connector 813.
Each groove 812, 814 further comprises a blocking surface 815, 815’ arranged inside said groove 812, 814 for blocking a movement of capturing protrusions along the pair of grooves 812, 814 and a doorstep element 816, 816’ arranged inside said groove 812, 814 near said end of the second connector 813 at a distance from the blocking surface 815, 815’for releasably holding one pair of protrusions of the first connector (see Figure 8C) inside the pair of grooves 812, 814 between the doorstep 816 and the blocking surface 815 of each groove.

Figure 8C shows a plane view of a second assembled state of the rod shaped second connector 800 and a first connector 100. The first pair of capturing protrusions
The blocking surface 815 and the doorstep 816 cooperatively and releasably hold the first pair of protrusions 128 of the first connector 100 inside the pair of grooves 814, thereby supporting a rotation of the second connector 800 about a first axis Pl of the capturing protrusions in a second assembled slate of the second connector 800 and a first connector 100.
The first pair of protrusions 128 is easily introduced in the distance between the doorstep 816 and the blocking surface 815 by sliding said pair of capturing protrusions 129 from the end of the second connector 813 along the pair of grooves 814 over the doorstep 816. When sliding the pair of capturing protrusions 128 over the doorstep 816, the jaws pair 120 may resiliently be move apart slightly to support the sliding movement of the capturing protrusions 128 over the doorstep 816. The distance between the doorstep 816, 816’ and the blocking surface 815, 815’ is suitably selected to allow only one pair of protrusions to be introduced and releasably held between the doorstep 816, 816’and the blocking surface 815, 815’. This arrangement enhances, that not both pairs of capturing protrusions 128, 126 are introduced into the pair of grooves 812, 814. As such, the second assembled state may be easily and controllably obtained by connecting the second connector 800 to the first connector 100.
In an alternative example of a second assembled state (not shown), the first connector 100 is connected to the second connector 800 by introducing the first pair of capturing protrusions 128 into the other pair of grooves 812.

Figure 9C shows a side view on the second connector piece 900 when looking in the direction of the first longitudinal axis LI of the body 910 at the first end 913 of the rod shaped element 900.
The body 910 further comprises two pairs of grooves 912, 914 distributed over the peripheral surface of the body 910. Each pair of grooves 912, 914 extends along the longitudinal axis LI. A first pair of grooves 912 is located at a twisting angle of 90 degrees with respect to the second pair of grooves 914 about the longitudinal axis LI.
A first pair of grooves 912 extends up to a first end 913 of the rod shaped element and a second pair of grooves 914 extends up to a second, opposite end 913’ of the rod shaped element. Optionally each pair of grooves 912, 914 extends up to both ends 913, 913’of the rod shaped element.
Each groove 912, 914 further comprises a blocking surface 915, 915’ arranged inside said groove 912, 914 for blocking a movement of capturing protrusions along the pair of grooves 912, 914 and a doorstep element 916, 916’ arranged inside said groove 912, 914 near said end of the second connector 913, 913’ at a distance from the blocking surface 915, 915’for releasably holding one pair of protrusions of the first connector (see Figure 9C) inside the pair of grooves 912, 914 between the doorstep 916 and the blocking surface 915 of each groove.
As shown in Figure 9C, each of the grooves 912, 914 has a shape of a V groove wherein the V groove has a span angle a as shown in figure IC. The angle span a is selected in the range of 85 till 100' .The doorstep 916, 816 may be shaped protruding over a part of a depth of the groove 912, 914 and extending over a part of the width of the groove 912, 914, as shown in Figures 9A - 9C.
In particular, the blocking surface 915, 915’ is arranged at a distance h from the corresponding end 913, 913’of the rod shaped connector, such that only one pair of protrusions of the first connector (see Figure 9C) is introduced in the pair of grooves 912, 914 front the corresponding end 913, 913’of the rod shaped connector 900.
Figure 9D shows a plane view of a second assembled state of the rod shaped second connector 900 and a first connector 100 and another first connector 100’.
At each end of the rod shaped second connector 900 a first connector 100, 100’may be connected to the rod shaped second connector. Both pairs of grooves 912, 914 extend parallel to one another along the longitudinal axis of the body LI. In this example the first connector 100 and the other first connector 100’both provide a rotational freedom about their first, outer, axis Pl, ΡΓ, respectively of the corresponding first pair of capturing protrusions 128, 128’ in connection to the rod shaped second connector 900. And the first axis Pl of the first connector 100 and the other first axis Pl’of the other first connector 100’are arranged at the twist angle of substantially 90 degrees rotation about the longitudinal axis of the second connector LI. In this way, the rod shaped second connector 900 may function as a ball a socket joint for connecting the first connector 100 to the other first connector 100’.
In the shown embodiment, a length of the rod shaped second connector 900 along its longitudinal axis LI is minimized and the blocking surfaces 915 and 915’ of the corresponding pairs of grooves 912, 914 are arranged, such that the first axis P! and the other first axis P(’ in the second assembled state are arranged substantially crossing each other. This arrangement further enhances the ball and socket functionality of the rod shaped second connector 900.
