Such toy building element is known from the toy building set known under the name of LEGO Technic. This toy build- ing set contains ia toy building elements in the form of straight beams provided with a number of openings that extend from the one side of the beam to the other. The toy building set also comprises toy building elements that consist of two beams that are assembled in a corner, wherein each of the beams is provided with at least one opening that extend (s) transversally of that beam. On their top faces, the toy building elements are provided with decored coupling studs, ie coupling studs that are configured as cylindrical pipes, whereas the bottom faces of the beams are provided with complementary coupling means in the form of outer skirts and, interiorly thereof, with downwardly protruding cylindrical studs.

Circular indentations are arranged around the openings to both sides of the beams, and such indentations serve to provide space for outwardly protruding collars on bush- ings that are also constituents of the toy building set and that can also be used to interconnect the beams or connect them with other toy building elements in the toy building set.

In case there are provided more openings in the same beam, they are arranged at a modular distance from each other, ie at the same distance from each other as the coupling studs on the top face of the beam. In practice, the openings are arranged centrally between the locations of the coupling studs.

In case of an angular element, ie a toy building element with two beam-like parts that are assembled at a corner, it is limited how far towards the corner an opening can be provided before it collides with the internal face of the other beam within the corner.

It is the object of the invention to provide a toy build- ing element as featured above, in which toy building ele- ment an opening is provided further towards the corner than was previously known.

This is obtained by configuring the toy building element such that the opening is arranged so far towards the cor- ner that the plane for the face of the plane internal face of the second beam-like part intersects the opening in the plane for the face of the plane internal face of the first beam-like part, and that the plane internal face of the second beam-like part is interrupted at a distance from the opening whereby a clearance is provided around the opening on the internal face of the first beam-like part.

By configuring the toy building element in this manner, additional play/building options are accomplished, since it is hereby possible to interconnect other toy building elements with the toy building element according to the invention further towards the corner than has been possi- ble so far.

Preferably, the opening has a circular cross section and an indentation is provided around said opening on the ex- ternal face as well as the internal face of the first beam-like part. It is the object of such indentation to provide space for outwardly protruding collars on eg bushings that are constituents of the toy building set.

Preferably, the indentation in the internal face of the beam-like part extends circularly around the one half of the opening and it continues around the remainder of the opening and out towards the edge at a width and a depth that correspond to the width and depth of the circular portion of the indentation. This configuration of the in- dentation is provided to avoid the need for providing decoring devices in the tool for the manufacture of the toy building element which would otherwise considerably increase the tool costs. This configuration is particu- larly advantageous in case of toy building elements with more beam-like parts that are angled relative to each other, since this would otherwise presuppose more decor- ing devices in various directions. The indentation has the shape of a roman arch around the opening that, be- sides adding to its functionality, also imparts thereto a harmonious appearance.

In a preferred embodiment the plane internal face of the second beam-like part is extended by an arched portion that arches inwards and collides with the plane internal face of the first beam-like part within the opening. Ex- tension of the plane part with an arched part configured in this manner enables that the internal faces of the first and the second beam-like parts become coherent thereby imparting additional strength to the toy building element in its corner region compared to the case where the internal faces were not coherent.

According to a particular embodiment of a toy building element according to the invention, it comprises four beam-like parts that combine to form a closed frame, openings being provided in all of the beam-like parts.

Since the invention makes it possible to provide openings close to the corners of the toy building elements, such frame element may be quite compact and yet be provided with comparatively many openings.

Preferably, the toy building element is provided with up- wardly extending coupling studs and with downwardly ex- tending skirts and pins that form coupling means that are complementary with the upwardly extending coupling studs which makes it compatible with other toy building ele- ments in commonly available toy building sets.

The invention will now be explained in further detail with reference to the drawings, wherein Figure 1 is a top plan perspective view of a first toy building element according to the invention; Figure 2 is a bottom plan perspective view of a second toy building element according to the invention; and Figure 3 is a bottom plan perspective view of a third toy building element according to the invention.

Figure 1 shows a first toy building element according to the invention. The toy building element comprises two beam-like parts 1,2, each of which having an internal face 3,4 and an external face 5,6. The external faces are not visible in Figure 1.

The beam-like parts 1,2 are also provided with openings 7 that are configured as cylindrical pipes that extend transversally to the beam-like parts 1,2 from the exter- nal face 5,6 to the internal face 3,4. The first beam- like part 1 is provided with five such openings 7 while the second beam-like part 2 is provided with one opening 7.

The openings 7 are configured such that they are able to receive and snap-lockingly secure bushings that are pro- vided in a toy building set of which the toy building elements are constituents. The bushings are tubular and provided with an outwardly extending collar that defines an end stop for the distance the bushing can be displaced into the opening 7. In the outer extremity of the bush- ing, a corresponding, outwardly extending collar is pro- vided which is, however, configured to be resilient, the bushing being in this case slotted in the longitudinal direction. Thus the bushing can be pressed into an open- ing 7 with its outer end squeezed together until the end stop is reached. In this position, the outer end has reached the other side of the opening 7, and the out- wardly extending collar engages behind the opening 7.

In order to allow space for the two outwardly extending collars of the bushing, without same extending beyond the internal and external faces 3,4,5,6 of the toy building element, these internal and external faces are provided with indentations 8 that extend around the openings 7.

The indentations can be configured as circular indenta- tions that extend around the openings 7 (as shown on the external faces of the toy building elements shown in Fig- ures 2 and 3), their being configured with a depth that corresponds to or slightly exceeds the height of the out- wardly extending collar of a bushing, and a diameter that

corresponds to or slightly exceeds the outer diameter of the outwardly extending collar of a bushing.

Alternatively, the indentations 8 can be configured as shown on the internal faces 3,4 of the toy building ele- ment shown in Figure 1, ie as a combination of a rectan- gle and a semicircle that extends around the opening 7 and all the way to the edge of the internal face 3,4. The indentations 8 serve to fulfil the same function as the above-mentioned circular indentations, viz to provide space for the outwardly extending collars of the bush- ings.

On its top face the toy building element is provided with upwardly extending coupling studs 9 that are, in the relevant case, decored, ie they each have the shape of a cylindrical pipe. The bottom of the toy building element is open (like the toy building elements shown in Figures 2 and 3) and by means of the external walls and down- wardly extending pins they form coupling means that are complementary with the coupling studs 9.

The coupling studs 9 are arranged at a modular distance from each other which means that the toy building element is compatible with other toy building elements with cou- pling studs arranged at the same modular distance. In a corresponding manner the openings 7 are arranged at a modular distance from each other and in the specific case, the openings 7 are arranged between the coupling studs 9.

As will appear the one opening 7 in the first beam-like part 1 is arranged far towards the corner between the two beam-like parts 1,2. This opening 7 is arranged so far towards the corner that normally it would collide with the internal face 4 of the second beam-like part. In or-

der to prevent this from happening, the plane portion of the internal face 4 is interrupted at a distance from the internal face 3 whereby a clearance is provided around this opening 7.

In the toy building element shown in Figure 1, the inter- nal face 4 is extended by an arched part 10 that arches inwards and abuts on the plane internal face 3 of the first beam-like part 1 within the opening 7.

A thin flap 11 of material extends across the space be- tween the arched portion 10 and the internal face 3, said flap on the one hand imparting strength to the toy build- ing element and rigidity in the corner region, and on the other hides the space between the arched portion 10 and the internal face 3 when the toy building element is viewed from above.

Figure 2 shows a further toy building element according to the invention. The toy building element shown com- prises four beam-like parts 21,22,23,24 that are each provided with one or more openings 7, and the four parts 21,22,23,24 combine to form a closed frame element. In each of the beam-like parts 23,24 three openings 7 are provided whereas the two remaining beam-like parts 21,22 are each provided with one opening 7. The external faces of the beam-like parts 21,22,23,24 are provided with cir- cular indentations 25 around the openings 7 while the in- ternal faces are provided with indentations 8 that are configured as a combination of a rectangle and a semicir- cle that extends around the opening 7 and all the way to the edge of the internal faces.

The toy building set shown in Figure 2 is shown from the bottom, which is open, the internal and external walls of the toy building element combining with pins 26 to form

coupling means that are complementary to the coupling studs 9 provided on the top face of the toy building ele- ment.

The corners of the toy building element are configured like the corner on the toy building element shown in Fig- ure 1, ie with arched portions 10 located in extension of the plane internal faces of the beam-like parts 21,22.

Figure 2 clearly illustrates how the arched parts 10 abut on the internal faces on the adjacent beam-like parts 23,24 within the openings.

All four corners being configured in this manner makes it possible to provide the toy building element shown with a total of eight openings 7 as shown despite its compact- ness.

Figure 3 shows a further toy building element according to the invention with four beam-like parts 31,32,33,34.

Also in this toy building element, two beam-like parts 33,34 are provided with three openings 7 while the two remaining beam-like parts 31,32 are each provided with one opening 7. The external faces of the beam-like parts 31,32,33,34 are provided with circular indentations 25 around the openings 7 whereas the internal faces are pro- vided with indentations 8 that are configured as a combi- nation of a rectangle and a semicircle that extends around the opening 7 and all the way to the edge of the internal faces.

The toy building element shown in Figure 3 also has an open bottom, its internal and external faces combining with pins 26 to form coupling means that are complemen- tary to the coupling studs 9 provided on the top face of the toy building element.

As opposed to the toy building elements described above, this toy building element is not provided with an arched extension on some of its internal faces. In contrast, the internal faces of the beam-like parts 31,32 are merely interrupted at a distance from the openings 7 configured at the corners transversally to the beam-like parts 33,34. Thus, a slot 27 is provided between the abutting internal faces, said slot 27 having a suitable width, eg at least corresponding to the height of a protruding col- lar on a bushing for the toy building set.

This arrangement, too, makes it possible to provide the toy building element shown with a total of eight openings 7 as shown despite its compactness.
