Description

CONNECTABLE ELEMENT FOR CREATING CHAINS AND SPATIAL STRUCTURES
The invention relates to a connectable element which can be used as a toy or a pedagogic tool. Several connectable elements may be connected into chains. To one first chain, a second chain may be connected, having a longitudinal direction that is different from the longitudinal direction of the first chain.
The patent publication WO 2006/083084 discloses a puzzle of pieces that are put together into chains. The pieces may have a polygonal shape like a triangle, rectangle, hexagon and so on. The pieces comprise an upper half and a lower half which may be joined together and separated. Two adjacent pieces are held together by a rigid connecting link. A first connecting link is threaded onto a centre pin projecting upwards in a lower piece half. A disc of a soft material is threaded onto the centre pin. If desirable, a second connecting link may be threaded onto the centre pin before the upper piece half is threaded onto the centre pin to lock the connecting links by being pressed into position. The disc of the soft material holds the connecting links, so that the assembly does not rattle and appear loose.
The patent publication WO 2006/083084 thus discloses a puzzle in which each piece comprises at least four different parts. For small children it is difficult to put the pieces together. The puzzle contains small parts. The puzzle also has the drawback of pieces that lack either the bottom part, the top part or the connecting link being unusable. The geometric possibilities of the puzzle are limited to the shape of the piece. Triangular pieces cannot be combined with, for example, rectangular pieces or hexagonal pieces as the pieces are laid edge to edge. The rigid connecting link allows the puzzle to be laid on a flat surface only.
The invention has for its object to remedy or reduce at least one of the drawbacks of the prior art or at least provide a useful alternative to the prior art. The object is achieved through features which are specified in the description below and in the claims that follow.
The invention relates to a connectable element that comprises a centre piece and a connecting piece, the centre piece including a connecting portion and at least one encircling groove; and the connecting piece including an end portion and an eye in a portion; the end portion of the connecting piece being attached to the connecting portion of the centre piece, and the eye complementarily fitting the encircling groove of an adjacent centre piece.
Two adjacent centre pieces may have the same dimension, and the connectable elements may be uniform and of the same size. Alternatively, the adjacent centre pieces may be of different dimensions and the connecting pieces may have different diameters in their respective eyes for them to complementarily fit the encircling groove of the adjacent centre piece.
The connecting piece may comprise an elastic material.
The end portion of the connecting piece may be attached internally in the centre piece. The centre piece may be provided with a pin internally, and the end portion of the connecting piece may be provided with an eye that is complementary to the pin. The end portion of the connecting piece may be provided with a thickening that fits internally in the centre piece. The end portion of the connecting piece may be provided with an eye that surrounds the connecting portion of the centre piece.
The centre piece may comprise an upper half and a lower half, and at least one of the halves may be provided with at least one projecting element for joining the two halves. The element may consist of a pin. The element may consist of welding lugs.
The centre piece may include at least one encircling groove on each side of the connecting portion. The encircling groove may be of a circular shape.
The end portion of the centre piece may be of a circular shape. The end portion of the centre piece may be formed as a polygon. The end portion of the centre piece may include an end face, and the end face may be provided with information.

Figures 13A-D show the invention in a tenth embodiment; A: in a side view, B: in a top view, C: in a perspective view and D: in an exploded view. In the drawings, the reference numeral 1 indicates a connectable element according to the invention. The connectable element 1 comprises a centre piece 2 and a connecting piece 3. At one end portion 30, the connecting piece 3 is attached to the centre piece 2. The connecting piece 3 is provided with an eye 31 in a portion 39. The connecting piece 3 consists of an elastic material such as a natural rubber, a synthetic rubber or an elastomer. The elastomer may have a hardness of, for example, Shore A50 or Shore A70. The elastomer may be a thermoplastic elastomer. The thermoplastic elastomer may be a thermoplastic polyurethane. A suitable material may also be a thermosetting plastic. A suitable material may be a silicone rubber, a butyl rubber or a butadiene rubber. The eye 31 is formed in such a way that it can be threaded onto a centre piece 2 of an adjacent connectable element 1. The centre piece 2 may consist of a hard material. The hard material may be a plastic material, such as a thermoplastic. ABS plastic is an example of a suitable material. Polyethylene and polystyrene are examples of other suitable materials. In an alternative embodiment, the centre piece 2 may consist of a natural material such as a wooden material or a metallic material. In a further alternative embodiment, the centre piece 2 may consist of a resilient material.
The centre piece 2 includes at least one encircling groove 21. The groove 21 is positioned at the side of the connecting piece 3 which is attached to the connecting portion 23 of the centre piece 2.
The centre piece 2 may comprise two parts, a lower half 20 and an upper half 29. At least one of the halves 20, 29 may include one or more projecting welding lugs 25. The welding lugs 25 are provided with welding surfaces 27 which, when the two halves 20, 29 are joined, lie in contact with the opposite half 20, 29. The two halves 20, 29 may be welded together by vibration welding as is known in the art.
The peripheral edge surfaces 26 of the welding lugs 25 form the connecting portion 23. In an alternative embodiment as shown in figures 11, 12, the connecting portion 23 is formed of the inner edge surfaces 28 of the welding lugs 25.
The centre piece 2 may include a plurality of encircling grooves 21 as shown in figures 2-4. The encircling grooves 21 may be positioned on both sides of the connecting portion 23.
In an end portion 30, the connecting piece 3 may be provided with an eye 33 that complementarily fits the connecting portion 23, so that the eye 33 encloses the centre piece 2 as is shown in figures 1-4. The eye 33 of the connecting piece 3 is positioned between the two halves 20, 29 before the halves 20, 29 are attached to each other, as shown in figures ID, 2C-4C. After the halves 20, 29 have been joined, the connecting piece 3 may be rotatably anchored to the centre piece 2. By choosing suitable diameters for the connecting portion 23, the eye 33 and the end portions 22 of the halves 20, 29, and a suitable hardness for the material of the connecting piece 3, it may be very difficult to twist the connecting piece 3 out of the connecting portion 23.
In most of the figures, the centre piece 2 is shown with a circular cross section, and the eye 33 is also shown as a circular through opening in the connecting piece 3. The invention is not limited to a circular geometry. An alternative embodiment is shown in figure 10. In this embodiment, the centre piece 2 is formed with a hexagonal circumference. The encircling grooves 21 are also hexagonal, and the eye 33 is of a hexagonal shape. The centre piece 2 may also be formed in other polygonal shapes (not shown), such as with a square circumference, a pentagonal circumference or an octagonal circumference. Correspondingly, the grooves 21 and the eye 33 may be formed with a square shape, a pentagonal shape or an octagonal shape. An elliptic shape is also possible.
In a further alternative embodiment, one end portion 22 or both end portions 22 of the centre piece 2 may be formed with a polygonal shape, whereas the grooves 21, the connecting portion 23 and the eye 31 are formed with a circular shape, as shown in figure 13.
In an alternative embodiment, at least one half 20, 29 may include a pin 4 projecting upwards. The pin 4 projects up from the internal surface of one half 20, 29 in the direction of the other half 20, 29. The connecting piece 3 tapers in its end portion 30 so that the end portion 30 can be positioned inside the centre piece 2, as shown in figure 11. A smaller eye 33' is formed in such a way that it complementarily fits the pin 4 and may be treaded onto the pin 4. The pin 4 is welded to the opposite half 20, 29. This embodiment has the advantage of the connecting piece 3 being fixedly anchored inside the centre piece 2 and not being releasable from the centre piece 2 without the centre piece 2 or the connecting piece 3 being destroyed, which requires great force. Trials have shown that the connecting piece 3 first deforms, in order then to snap in the portion 39, rather than the connecting piece 3 snapping in the end portion 30.
In a further alternative embodiment, the connecting piece 3 may be provided with a thickening 35 as shown in figure 12. The connecting piece 3 tapers in its end portion 30, so that the end portion 30 may be positioned inside the centre piece 2. The thickening 35 is formed in such a way that it complementarily fits an internal space formed by the inner edge surfaces 28 of the welding lugs 25 and the inner end faces of the halves 20, 29. This alternative embodiment also has the advantage of the connecting piece 3 being fixedly anchored inside the centre piece 2 and not being releasable from the centre piece 2 without the centre piece 2 or the connecting piece 3 being destroyed, which requires great force.
In a further alternative embodiment shown in figure 8, the end portion 30 of the connecting piece 3 may project beyond the periphery of the centre piece 2 and the end portion 30 be provided with a smaller eye 33' . At least one of the halves 20, 29 is provided with a pin 4. In this embodiment, the halves 20, 29 are provided with welding lugs 25. The pin 4 is welded to the opposite half 20, 29. This embodiment also has the advantage of the connecting piece 3 being fixedly anchored inside the centre piece 2 and not being releasable from the centre piece 2 without the centre piece 2 or the connecting piece 3 being destroyed, which requires great force. It may also be an advantage that the connecting piece 3 is rotatable around the axis of the centre piece 2. It may also be an advantage that several assembled connectable elements 1 have a uniform appearance by the connecting piece 3 being visible over the entire circumference of the connecting portion 23, as is shown in figures 1-7 as well.
In a further alternative embodiment shown in figure 9, the end portion of the connecting piece 3 may project beyond the periphery of the centre piece 2, and the end portion 30 may be provided with a thickening 37 and a through hole 34 encircling the thickening 37. The thickening 37 is positioned inside the centre piece 2. The welding lugs 25 of the two halves 20, 29 are positioned in the holes 34 before the halves 20, 29 are joined together. This embodiment also has the advantage of the connecting piece 3 being fixedly anchored in the centre piece 2 and not being releasable from the centre piece 2 without the centre piece 2 or the connecting piece 3 being destroyed, which requires great force. It may also be an advantage that several assembled connectable elements 1 have a uniform appearance by the connecting piece 3 being visible over the entire circumference of the connecting portion 23 as is also shown in figures 1-7.
In an alternative embodiment, the connecting piece 3 is threaded loosely onto the centre piece 2. In this embodiment, one encircling groove 21 of the centre piece 2 constitutes the connecting portion 23. The centre piece 2 may be solid or hollow.
The connecting piece 3 is formed from an elastic material so that the eye 31 can be threaded onto an adjacent centre piece 2 and positioned in a groove 21. This may be repeated so that several connectable elements 1 are linked together. As the connect- ing piece 3 is flexible, a number of connectable elements 1 may be joined together into a ring 5, for example, as shown in figure 5. Each connectable element 1 may be provided with two or more grooves 21. This enables the connection of several connectable elements 1 in different directions from one connectable element 1. Spatial structures 6 may thereby be built from a number of connectable elements 1 as well, as shown in figure 5.
The connectable elements 1 may be connected at different angles as shown in figure 6. When the encircling groove 21 is circular and the eye 31 is circular, the connectable elements 1 may be connected to each other at any angle.
One end face 70 of the centre piece 2 may be provided with information in the form of a letter, a numeric character, embossed printing, a symbol, a pictogram and the like. The centre piece 2 may be provided with information on both end faces 70, 79. The information on one end face 70 may be different from the information on the other end face 79. The centre piece 2 may be provided with a colour. Different centre pieces 2 may be provided with different colours. The end faces 70, 79 may be provided with a colour. The colour of the end faces 70, 79 may differ from the colour of the centre piece 2 in the grooves 21, and the colour of the end face 70 may differ from the colour of the end face 79.
The connectable element 1 may be used in a pedagogic connection. Several connectable elements 1 may be put together into words when the information of the end face 70, 79 is a letter. Such connectable elements 1 with a letter may also be used to create a crossword as shown schematically in figure 7. To a connectable element 1 provided with three groves 21, connectable elements 1 may be connected in four directions. A side chain may be formed anywhere on an established chain by a new connectable element 1 being threaded with its connecting piece 3 onto an unoccupied groove 21 in a centre piece 2 of the established chain. A number of connectable elements 1 may be joined into a bracelet showing a name.
The connectable element 1 may also be used in mathematics teaching when the end faces 70, 79 are provided with numeric characters and mathematical symbols.
Joining the two halves 20, 29 may be done in several ways as is known within the art. The halves 20, 29 may be glued together. The halves 20, 29 may be provided with projecting hooks that engage with latch grooves in the opposite half 20, 29 (not shown).
