Technical field of the invention

The invention relates to a method for assembling an arrangement. The invention also relates to a corresponding assemblable arrangement.

Background of the invention

Method for forming a three-dimensional object and a corresponding object is disclosed in EP1530990. The method and object according to EP1530990 is suitable for relatively small objects such as decorations, for example. Applying the method and object according to EP1530990 for larger objects such as interior design ele- ments for high spaces, echo cancellation elements, decorative pillars, cotes, artificial trees and other three-dimensional objects that require, for example, significant height carries certain practical problems.

Firstly, larger three-dimensional objects if created and manufactured as disclosed in EP1530990 are highly impractical to pack, store and transport as they require large packages in terms of height or width or both. Costs of packaging, storing and transportation of such larger three-dimensional objects are uneconomically high and need to be reduced. Also, larger three-dimensional objects if manufactured as disclosed in EP1530990 are difficult to assemble as each single element is relatively high or wide. A single person cannot assemble such larger three-dimensional objects independently. Depending on the space to which the object is to be placed it is also possible that the object needs to be assembled either outside or transported readily assembled as very high or wide objects require a lot of space for assembling as well and there are also potential safety issues in assembling them. Problems of assembling must be solved for such larger three-dimensional objects.

Further, manufacturing larger three-dimensional objects as disclosed in EP1530990 causes significant material waste. The more complex a single element of the three-dimensional object is, the more waste material is produced if the single element is manufactured in one piece only. Also, if during manufacturing even one of the elements of object turns out to be of low quality, the whole faulty ele- ment is wasted. In case of larger elements the amount of wasted materials in both cases becomes unecononnically high and causes unnecessary manufacturing costs. Both material waste and manufacturing costs thereto need to be reduced. Therefore, a method for assembling an arrangement and a corresponding assemblable arrangement are needed to solve the certain problems and limitations presented above.

In step 501 a first group (20, 30) of at least two first elements, (201 , 301 ) where an individual first element comprises all the characteristics of an individual element according Figures 1 a-1 d, is created. The first group (20, 30) of at least two first elements (201 , 301 ) is created and an individual first element comprises at least one first edge surface 101 and at least one second edge surface 102 that are on a distance from each other, at least one slot 105, and a neck 106 with less height than the distance of the at least one first edge surface 101 and the at least one second edge surface 102.

Advantageously, when fitted together, the first edge surfaces 101 of the at least two ele- ments (201 , 301 ) of the first group (20, 30) of elements and the first edge surfaces 101 of the at least two elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements may be positioned on different levels compared to each other. When fitted together, the first edge surfaces 101 of the at least two elements (201 , 301 ) of the first group (20, 30) of elements and the first edge surfaces 101 of the at least two elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements are positioned on different levels compared to each other. Also, first edge surfaces 101 of the at least two elements (201 , 301 ) of the first group (20, 30) of elements and the first edge surfaces 101 of the at least two elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements may be positioned on different levels compared to each other step-wise.

Next, either step 507 or 51 1 is taken. If step 51 1 is chosen at this point of the pro- cess, no further layers (23-24, 35-36) will be added to the arrangement and assembling the arrangement according to the invention is completed.

Advantageously, if step 507 is chosen, at least one other layer (25, 37-39) is eventually added to the arrangement according to the invention. In step 507 at least one third group (22, 32-34) of at least two first elements (221 , 321 , 331 , 341 ) is created. The at least one third group (22, 32-34) of at least two third elements (221 , 321 , 331 , 341 ) is created and an individual third element comprises at least one first edge surface 101 and at least one second edge surface 102 that are on a distance from each other, at least one slot 105, and a neck 106 with less height than the distance of the at least one first edge surface 101 and the at least one second edge surface 102. For the at least one third group (22, 32-34) of at least two third elements (221 , 321 , 331 , 341 ), the at least two third elements (221 , 321 , 331 , 341 ) can be fitted at least partially together crosswise so that at least one slot 105 of at least one third element (221 , 321 , 331 , 341 ) is at least partially dimen- sioned against a neck 106 of at least one other third element (221 , 321 , 331 , 341 ).

In step 508 the at least two third elements (221 , 321 , 331 , 341 ) are fitted at least partially together correspondingly. Further, the at least two third elements (221 , 321 , 331 , 341 ) are fitted at least partially together crosswise so that the at least one slot of 105 at least one third element (221 , 321 , 331 , 341 ) is at least partially dimensioned against the neck 106 of at least one other third element (221 , 321 , 331 , 341 ).

More advantageously, according to step 508, the method further comprises fitting the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of one group (20- 22, 30-34) of at least two elements at least partially together crosswise together so that the at least one slot (105) of at least one individual element (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) is at least partially dimensioned against the neck (106) of at least one other individual element (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the same group of at least two elements (20-25, 30-39).

In step 509 the at least one second edge surface 102 of at least one third element (221 , 321 , 331 , 341 ) is also fitted at least partially against at least one first edge surface 101 of at least one element on the previous layer (24, 36-38) of the arrangement. The at least one second edge surface 102 of at least one third element (221 , 321 , 331 , 341 ) is fitted at least partially along the length of the at least one first edge surface 101 of at least one element (21 1 , 31 1 ) on the previously added layer (24, 36-38) on the arrangement.

In step 510 fitting together at least one third group (32-34) of at least two third elements according to steps 507-508 causes adding at least one layer (37-39) to the arrangement. On the now assembled arrangement the first edge surfaces 101 of the at least two first elements (201 , 301 ) of the first group (20, 30) of elements, the first edge surfaces 101 of the at least two second elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements and the first edge surfaces 101 of the at least two third elements (221 , 321 , 331 , 341 ) of the at least one third group (22, 32-34) of elements are at least partially positioned on the same level compared to each other. Advantageously, on the now assembled arrangement, the first edge surfaces 101 of the at least two first elements (201 , 301 ) of the first group (20, 30) of elements, the first edge surfaces 101 of the at least two second elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements and the first edge surfaces 101 of the at least two third elements (221 , 321 , 331 , 341 ) of the at least one third group (22, 32-34) of elements may be positioned on different levels compared to each other. Also, on the now assembled arrangement, the first edge surfaces 101 of the at least two first elements (201 , 301 ) of the first group (20, 30) of elements, the first edge surfaces 101 of the at least two second elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements and the first edge surfaces 101 of the at least two third elements (221 , 321 , 331 , 341 ) of the at least one third group (22, 32-34) of elements may be positioned on different levels compared to each other step-wise.

More advantageously, on the now assembled arrangement, the first edge surfaces 101 of the at least two first elements (201 , 301 ) of the first group (20, 30) of ele- ments, the first edge surfaces 101 of the at least two second elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements and the first edge surfaces 101 of the at least two third elements (221 , 321 , 331 , 341 ) of the at least one third group (22, 32-34) of elements are positioned on different levels compared to each other. Finally, the first edge surfaces 101 of the at least two first elements (201 , 301 ) of the first group (20, 30) of elements, the first edge surfaces 101 of the at least two second elements (21 1 , 31 1 ) of the second group (21 , 31 ) of elements and the first edge surfaces 101 of the at least two third elements (221 , 321 , 331 , 341 ) of the at least one third group (22, 32-34) of elements are positioned on different levels compared to each other step-wise.

Advantageously, according to the method, steps 507-510 may now be repeated if further layers should be added to the arrangement. If no further layers should be added to the arrangement, the method is completed by choosing step 51 1 and the arrangement according to the invention is assembled.

Very advantageously, according to steps 502, 504-505 and 508-51 1 , the method further comprises fitting the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of one group (20-22, 30-34) of at least two elements at least partially together crosswise together so that the at least one slot (105) of at least one individual element (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) is at least partially dimensioned against the neck (106) of at least one other individual element (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the same group of at least two elements (20-25, 30-39). The method according to steps 502, 504-505 and 508-51 1 , also comprises fitting at least one second edge surface 102 of at least one individual second or third element (21 1 , 221 , 31 1 , 321 , 331 , 341 ) at least partially against at least one first edge surface 101 of at least one individual first, second or third ele- ment (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) on the previous layer (23-25, 35- 39) of the arrangement.

Very advantageously, the method according to steps 501-51 1 further comprises forming a three-dimensional object by assembling the arrangement (25-25, 35- 39).

Finally, the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the arrangement, before assembly, may be packaged to container. Advantageously, the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the arrangement, before assembly, may be packaged to container so that elements similar to each other are packed together to save packaging space. Advantageously, the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the arrangement, before assembly, may be packaged to a container so that elements similar to each other that belong to the same group of elements (20-22, 30-34) are packed together to save packaging space. More advantageously, the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) of the arrangement, before assembly, may be packaged to a container so that elements similar to each other that belong to the same group of elements (20-22, 30-34) are packed together to save packaging space and the container itself guides how the individual elements (201 , 21 1 , 221 , 301 , 31 1 , 321 , 331 , 341 ) should be packed to the container.

It is obvious to a person skilled in the art that the basic idea of the invention may be implemented in various ways and is not limited to a certain number of individual elements, order of connecting or fitting together individual elements, number of layers in the arrangement, form of an individual element or form or number of connecting elements or joint parts. The invention and the embodiments thereof are thus not restricted to the above examples but may vary within the scope of the claims. Different features may thus be left out, processed or replaced by equivalent ones.
