Description

Field of invention

[0001] The present invention relates to a system and a method for assisted construction by using a body structure such as a bead plate. The present invention also relates to a system comprising an improved body structure (e.g. a bead plate).

Prior art

[0002] Plate constructions is very popular among children. For decades children have been building images (constructions) on body structures such as bead plates (also known as pegboards) comprising a plurality of pins each protruding from a base portion. The pins are configured and arranged to receive a bead, however, positioning of the beads in the correct positions can be challenging for children.

[0003] Therefore, systems have been developed to assisting uses (typically children) to build an image on a bead plate comprising a plurality of pins each protruding from a base portion. It is, by way of example, known to apply digital systems for the purpose of assisting a user to build an image on a bead plate. This is done by fixing the bead plate to a tablet or another illumination device. When the bead plate has been fixed, the bead plate can be illuminated for the purpose of assisting the user to build an image on a bead plate.

[0004] It is, however, difficult to distinguish between colours that only differ slightly when using the prior art assisting systems. Therefore, the images typically apply colours that are easy to distinguish from each other.

[0005] Thus, there is a need for a system and a method which enables a more user-friendly assistance, and which reduces or even eliminates the above-mentioned disadvantages of the prior art.

[0006] It is an object to provide a system that makes it possible to ease the construction process and makes it possible to build an image that requires building elements (e.g. beads, building structures or building bricks) of colours that only slightly differs from each.

Detailed description of the invention

[0055] Referring now in detail to the drawings for the purpose of illustrating preferred embodiments of the present invention, a system 20 of the present invention is illustrated in Fig. 1. The system 20 is a system configured to indicating the positions of building elements formed as beads 4 on a body structure formed as a bead plate 2 in order to build a predefined image like the heart shown in Fig. 3A, Fig. 3B and Fig. 3C.
The system 20 comprises an illumination device 10 having a display portion provided with (or configured to be brought into a configuration, in which the display portion is provided with) a number of activated illumination areas 12, 12", wherein each activated illumination area 12, 12' emits light and thus provides an illumination 14. For simplicity, only one illumination 14 is shown, however, in practice, all activated illumination areas 12, 12" will emit light and thus provide illumination 14. The illumination areas 12, 12" can be activated by using the illumination device 10. In a preferred embodiment, the illumination device 10 comprises a control unit 64 configured to select where to provide illumination areas 12, 12" of a first colour (e.g. red) or a first selection of colours (e.g. yellow and blue). In a preferred embodiment, the illumination device 10 comprises an interface by which it is possible to read instructions and/or to select among options provided in a menu or to enter values, instructions or text.

[0056] In one embodiment, the illumination device 10 is configured to provide illumination 14 of a predefined colour, preferably corresponding to the colour of the bead(s) to be arranged in the position(s) indicated on a bead plate 2 arranged above illumination device 10.

[0057] In another embodiment, the illumination device 10 is configured to provide illumination 14 of white light (a combination of lights of different wavelengths in the electromagnetic spectrum). In this embodiment the illumination device 10 is configured to indicate the colour of bead(s) to be arranged in the position(s) indicated on a bead plate 2 arranged above illumination device 10 by other means (e.g. text or sound such as "Please, place blue beads into the illuminated pins".

[0058] The user may download an image from an internal source such a local storage 46 of the illumination device 10, from an external source such as a server 40 in a manner that includes communication 39, 39' between the illumination device 10 and the server 40 or from the Internet 42 in a manner that includes communication 38, 38' between the illumination device 10 and the Internet 42. Besides, communication 38 may be carried out between the server 40 and the Internet 42.
The illumination device 10 may be a tablet, a smartphone a computer or a dedicated electric device comprising a display unit configured to provide activated illumination areas 12, 12" in order to indicate the colour of the bead(s) to be arranged in predefine position(s) indicated on a bead plate 2 arranged above illumination device 10.

[0059] In Fig. 1 a transparent bead plate 2 is arranged above the illumination device 10. The bead plate 2 is intended to be arranged on the display unit (top portion) of the illumination device 10 in a fixed and predefined manner, so that the position of the activated illumination areas 12, 12" can be used to indicate the colour of the bead(s) to be arranged in predefine position(s) indicated on a bead plate 2 arranged above illumination device 10. Accordingly, it is required to know the position of the pins 6 of the bead plate 2 and the position at which the bead plate 2 is attached to/arranged on the illumination device 10. In a preferred embodiment, the illumination device 10 comprises an indication structure 44 indicating the position, at which the bead plate 2 is required to be attached to/arranged on the illumination device 10.

[0060] The bead plate 2 comprises a flat structure 8, from which a plurality of pins 6 protrude. The pins 6 are configured to receive beads (see Fig. 2B).

[0061] Fig. 2A illustrates a system 20 according to the invention in a configuration, in which the positions of a first predefined colour (the pins 6 at which red beads have to be attached on the body structure formed as a bead plate 2 arranged on the illumination device 10) is indicated on a plurality of coupling elements formed as pins 6 of the bead plate 2 by illumination of the bead 2 plate by means of an illumination device 10 arranged below the bead plate 2.

[0062] The bead plate 2 comprises a flat structure 8 formed as a transparent planar plate. A plurality of pins 6 protrudes from the flat structure 8. The longitudinal axes of the pins 6 extend perpendicular to the plane along which the flat structure 8 extends.
Since the system 20 enables that a single colour is indicated by means of the illumination device 10, the system enables that colours that only slightly differs can be used when constructing an image. This approach is not possible if all colours are indicated at one time. Accordingly, it is a major advantage that the system 20 and the method according to the invention enables selection of a subset of colours to be indicated by means of the illumination device 10. This subset of colours may be a single colour (e.g. a blue colour, a read colour, a green colour or another predefined colour). The subset of colours may include several colours (e.g. read and blue, green and purple or orange, pink and green).

[0063] Fig. 2B illustrates the system 20 shown in Fig. 2A, in a configuration, in which building elements formed as beads 4 of a first predefined colour have been attached to the pins of the bead plate 2, while the bead plate 2 is being illuminated by means of the illumination device 10.

[0064] Fig. 2C illustrates the system 20 shown in Fig. 2B, in a configuration, in which the position of a second predefined colour is indicated on a plurality of the coupling elements formed as pins 6', 6" (not being illuminated in Fig. 2A) of the bead plate 2. This indication is made by illuminating the bead plate 2 by means of the illumination device 10 arranged below the bead plate 2. In a preferred embodiment, the bead plate 2 is provided with a positioning unit (not shown) configured to keep the bead plate 2 in a fixed position and orientation relative to the illumination device 10. The positioning unit may be provided as an anti-slip structure provided at the bottom end of the bead plate 2. The anti-slip structure may be provided as a mat providing a friction large enough to maintain the mat and thus the bead plate 2 in a fixed position and orientation relative to the illumination device 10.

[0065] Instead of indicating only a single colour by means of the illumination device 10, it is possible to indicate a group of colours defining a subset of the colours of the image to be constructed by using the bead plate 2. This may be done, e.g. by illuminating a plurality of pins 6' of the bead plate 2 by means of the illumination device 10.
Fig. 2D illustrates the system 20 shown in Fig. 2C, in a configuration, in which building elements formed as beads 4' of a second predefined colour have been attached to the pins of the bead plate 2, while the bead plate 2 is being illuminated by means of the illumination device 10.

[0066] Fig. 3A illustrates the system 20 shown in Fig. 2D, in a configuration, in which the position of a third predefined colour is indicated on a plurality of coupling structurs formed as pins 6" of the body structure formed as a bead plate 2 by illuminating these pins 6" by means of the illumination device 10, onto which the bead plate 2 is arranged. It can be seen that the beads 4 of the first colour and the beads 4' of the second colour are maintained in their position, onto which they were arranged as explained with reference to Fig. 2D.

[0067] Fig. 3B illustrates the system 20 shown in Fig. 3A, in a configuration, in which beads 4" of a third predefined colour have been attached to the remaining pins (indicated with reference number 6"in Fig. 3A) of the bead plate 2, while the bead plate 2 is being illuminated by means of the illumination device 10.

[0068] Fig. 3C illustrates the system 20 shown in Fig. 3B, in a configuration, in which the bead plate 2 has been removed from the illumination device 10. The beads 4, 4', 4" arranged on the bead plate 2 constitute a construction (e.g. an image) 48 of a heart. The beads 4, 4', 4" may now be heated e.g. by means of a flat iron in order to join the beads 4, 4', 4". It may be an advantage to use flat bottom iron.

[0069] It can be seen that the illumination device 10 has a plurality of activated illumination areas 12" each emitting light and thus provides an illumination that assisted the user to position the beads 4" in the pins (6" shown in Fig. 3A).

[0070] Fig. 4A illustrates a first segment 22 of bead plate 2 according to the invention, whereas Fig. 4B illustrates a second segment 22 the bead plate 2 shown in Fig. 4A. The first segment 22 is configured to be attached to the second segment 22'. Fig. 4C illustrates a cross-sectional view of the segment 22 shown in Fig. 4A, whereas Fig. 4D illustrates a cross-sectional view of the segment 22' shown in Fig. 4B.

[0071] The first segment 22 and the second segment 22' each comprises a flat structure provided with pins (not shown for reasons of simplicity). The segments 22, 22' have rectangular body portion having a first side length L₃ in and a second side length L₄. In one embodiment, the first side length L₃ corresponds to the second side length L₄.

[0072] In another embodiment, the first side length L₃ differs from the second side length L₄.

[0073] The first segment 22 is provided with attachment structures 16, 16' extending in extension of the rectangular body portion of the first segment 22. The attachment structures 16, 16' are positioned in side by side manner, in which a space is provided between adjacent attachment structures 16, 16'. An angled portion 28, 28' is provided at each side structure of each of the attachment structures 16, 16'.

[0074] In Fig. 4C it can be seen that every second attachment structure 16 is arranged in a higher level than the remaining attachment structures 16'. Likewise, in Fig. 4D it can be seen that every second attachment structure 18 is arranged in a higher level than the remaining attachment structures 18'. Each of the attachment structures 16, 16', 18, 18' comprise an engagement portion 32, 32' configured to engage with a corresponding engagement portion 32, 32' of an attachment structure 16, 16', 18, 18' of the adjacent segment 22, 22' that is attached by means of the attachment structures 16, 16', 18, 18'.

[0075] Each of the attachment structures 16, 16', 18, 18' comprise a flat portion 34, 34' provided next to the engagement portion 32, 32'. The attachment structure 16 (positioned in a high level) of the segment 22 shown in Fig. 4C is configured to be engagingly attached to the corresponding attachment structure 18' (positioned in a low level) of the segment 22'. Accordingly, the engagement portion 32 of the attachment structure 16 of the segment 22 will engage with the engagement portion 32' of the attachment structure 18' of the segment 22'.

[0076] The length L₁ of the short attachment structures 16', 18' is smaller than the length L₂ of the long attachment structures 16, 18. Hereby, it is, as shown in Fig. 6A and Fig. 6B as well as Fig. 7A and Fig. 7B, possible to slide a segment 22'" into engagement with segments 22, 22', 22" already being attached to each other.

[0077] Fig. 5A illustrates a top view of the segments 22, 22' shown in Fig. 4A and Fig. 4B, in a configuration, in which the segments 22, 22' of a bead plate 2 are joint (detachably attached to each other). Fig. 5B illustrates a cross-section of the segments 22, 22' shown in Fig. 5A. The longitudinal axis X, the lateral axis Y as well as the normal axis Z of the second segment 22' are indicated in Fig. 5A.

[0078] The engagement portion 32 of the attachment structure 16 of the first segment 22 in brought into lockingly engagement with the corresponding engagement portion 32' of the attachment structure 18' of the second segment 22'. The longitudinal axis and the normal axis Z of the second segment 22' are indicated in Fig. 5B. It can be seen that the attachment structure 16 of the first segment 22 of the bead plate 2 can be brought out of engagement with the attachment structure 18' of the second segment 22' of the bead plate 2 by moving the attachment structure 16 along the normal axis Z of the second segment 22'.

In a preferred embodiment. the segments 22, 22', 22", 22'" are equally shaped in order to reduce the number of tools for manufacturing the segments 22, 22', 22", 22'". The segments 22, 22', 22" are already joint (detachably attached to each other), whereas the remaining segment 22'" is ready to be attached to the segments 22, 22".

[0080] In Fig. 6B, the segment 22'" has been detachably attached to the segments 22, 22". Accordingly, the bead plate 2 is assembled and comprises four segments 22, 22', 22", 22'" being attached to each other. It can be seen that an aperture 36 is provided at the central portion of the bead plate 2 at the position, at which all four segments 22, 22', 22", 22'" are attached to each other.
