Technical sphere
[0001] An invention refers to tinker-toys, containing assembly elements with connecting
means for demountable assembly of assembly elements.
Prior art
[0002] The technical result is the ability to reduce weight and volume of the construction
toy detail.
[0003] Parallelepipedal construction toy detail consists of two separate hollow elements.
The first element contains at least four protrusions on one of the faces and at least
one protrusion located on the opposite face, as well as side walls, and a second element
contains at least one protrusion. Both elements of the detail are designed for their
interconnection by tightly fitting the second element between the side walls of the
first element, and one of these elements of the detail contains at least one limit
well for bracing in the corresponding supporting platform of the other element, while
bothelements of the detail are made of molded paper pulp.
[0004] A utility model refers to tinker-toys, containing assembly elements with connecting
means for demountable assembly of assembly elements.
[0005] The closest in technical substance, i.e. the prototype, is a building block designed
as a rectangular parallelepiped, containing the lower and four side walls, at least
four cylindrical protrusions extending outward from the bottom and arranged in two
lines of opposite protrusions defining a square, tubular protrusion parallel to the
side walls on the inner surface of the bottom, the longitudinal axis of the tubular
protrusion passes through the center of the square with the possibility of contact
with the specified cylindrical protrusions of another block, with the specified tubular
protrusion and at least one side wall when indicated peripheries are geometrically
projected onto the bottom, whereby the cylindrical protrusions on one of these blocks
can be inserted into the clamping engagement with the tubular protrusion and the wall
of the other of the indicated blocks, while the inner diameter of the tubular protrusion
equals to the diameter of these cylindrical protrusions. (Ref.
US 3005282 A).
[0006] The known solution can be used as a tinker-toy, which is a set of blocks - particular
bricks of which various structures can be built, however, it has the following disadvantages.
[0007] The block is made as a single monolithic element and with small block size its weight
is also small. However, with a size gain of the blocks, their reliable connection
with each other will require a proportional increase in the thickness of the side
walls and the bottom thickness, comparable with the diameters of the tubular and cylindrical
protrusions. With block sizes comparable, for example, to the dimensions of a brick
or book, its weight, even if made of plastic, becomes unacceptable for the safe construction
of complex structures. Such heavy blocks cannot be used as toys, especially children's
toys as they are unsafe. For the same reason the known solution is problematic and
in some cases impossible to use when creating decorations, large art objects and other
similar structures.
[0008] The indicated drawback confines the scope of use of the known solution.
[0009] Another drawback is the excessively large volume required for storage and transportation
of the construction toy, containing many blocks. In particular, this drawback is relevant
for large blocks. This disadvantage brings inconvenience in storing and transporting
of large number of blocks.
[0010] The drawbacks also include high material consumption and the complexity in manufacturing
monolithic blocks, reducing their manufacturability.
Technical problem
[0011] The technical result is to expand the area of application due to the possibility
of reducing the weight of the construction toy detail, providing the possibility to
reduce the required volume for storage and transportation of the construction toy
details, reducing material consumption and increasing manufacturability.

Description of embodiment
[0016] Building block is made of molded paper pulp in the form of a hollow spacious structure
as a parallelepiped with a rectangular base and consists of two elements. The first
element of the block contains a face with at least four protrusions and side walls.
Indicated protrusions are external and are arranged in two lines, at the corners of
an imaginary square. The second element contains the opposite face with at least one
external protrusion on it, which is also external and oriented along the axis of the
specified square. Both of these elements of the block are made with the possibility
of their interconnection, so that in the assembled block a part of the second element
was inside the space of the first element engaged with its side walls
[0017] One of the indicated elements contains at least one limit well, located, for example,
along the axis of the specified imaginary square, but directed inward to the block,
i.e. towards another element and performing the function of supporting one element
on another element. In this case, the other element is provided with an appropriate
supporting platform for bracing in the specified limit well in the assembled block.
The supporting platform is made textured, the texture profile of which is consistent
with the profile of the limit well bottom. The textured surface may be a square indentation
at the bottom of the limit well and a corresponding square profile on the supporting
platform of another element. At the same time, two elements in the assembled block
touch each other with their perimeters and the places of interaction of the limit
wells with supporting platforms, of which there may be several. Such a connection
of the two elements provides inter-fixation of the positions of the first and second
elements in the assembled block eliminating the possibility of their relative displacement
or rotation.
[0018] External protrusions on opposite faces of the block can be executed in various sections:
round, square, star-shaped and others, satisfying the requirement of reliable connection
of mating adjacent construction block when building structures.
[0019] The side faces of the block, as well as the planes of the side surfaces of protrusions
and wells of the block are made with an inclination relative to the center line, which
ensures ease of manufacture and, as a result, an increase in the block manufacturability.
[0020] The size of the protrusions of the block and the distance between these protrusions
and the side walls are made with the possibility of ensuring the connection of adjacent
blocks by installing the blocks on top of each other. In this case, the protrusions
of the lower block are led into the indentations between the corresponding protrusions
of the upper block for center-to-center connection of the block, or between the protrusions
and the inner side wall of the upper block when connected out of alignment.
[0021] The inner side walls of the block are formed due to the texture of the second element,
which also provides the function of stiffeners that increase the rigidity of the block.
[0022] Around the perimeter of the second element edge the outward bend is made to brace
the edge of the side walls of the first element.
[0023] The height of the external elements corresponds to the depth of the indentations
between the protrusion and the side walls of the second element, so that during assembly
the adjacent blocks abut against each other with the corresponding surfaces.
[0024] The number of protrusions of the first element may be more than 4, for example, 4,
6, 8, etc. In case of 6 protrusions, we have two imaginary squares, since it is formed
with only four protrusions arranged in two lines. In case of 8 protrusions we have
three imaginary squares with their corresponding axial lines. In this case, the number
of protrusions of the second element will be, respectively, 1, 2, 3, etc.
[0025] Building block is used as follows.
[0026] Storage and transportation of block' elements are carried out separately. Moreover,
due to the inclination of the side profiles of walls and the fact that the elements
are hollow and the protrusion on one side corresponds to an indentation on the back
side of the corresponding element of the block, these elements can be coaxially inserted
into one another during storage. Storage and transportation of block' elements separately,
in an inserted state, saves about 75% of space compared with storing blocks assembled.
[0027] Two block's elements made of molded paper pulp are piece together so that the lower
edge of the side walls of the first element abuts against the edging of the second
element, and the supporting platform abuts against the corresponding area of the limit
well. The texturized execution of the supporting platform additionally stabilizes
the position of two elements of the detail, providing stiffness.
[0028] Assembled construction of the block is sufficiently rigid, which is ensured, also,
due to the inter-spacing of the planes fixing the position of the side walls from
each other. The value of the specified spacing is determined by the height of the
limit well. The position of the side walls in the upper part determines the integrity
of the first element, and the fixation of their position in the lower part determines
the second element with its texturized execution.
[0029] The connection of the two elements of the block is ensured by the density of the
installation of the second element inside the side walls of the first element, so
that the second element is covered by the side walls of the first element. In the
cases where a more rigid connection is required, both elements of the block can be
fastened by gluing along the perimeter and at the contact points of the elements through
the supporting platforms. The block assembled and glued in this way becomes non-assembled
block.
[0030] The dimensions of the protrusions, as well as the dimensions of the indentations
between them and the position of the protrusions relative to the side walls provide
an easy and reliable connection of adjacent details when creating improvised designs.
[0031] Details can be connected not only coaxially when the protrusions of one detail are
installed between the cylindrical protrusions of an adjacent detail, but also off-center,
when some of the protrusions can be used to connect to one adjacent detail, and part
can be used to connect to another detail, which allows you to create a wide variety
of constructions.
[0032] Due to the hollow design of the block, its weight is insignificantly dependent on
the size of the block, which makes it possible to manufacture and use both small bricks
of the construction toy and lightweight large blocks.
[0033] Building blocks ensure safety in use even when using large blocks of the building
bricks' size and above. Therefore, high safety in use allows using building blocks
also as toys for children.
[0034] Building block can be used to create decorations, single-action art objects, large
structures for public gatherings and celebrations, etc., which provides a wide implications
of the solution.
[0035] The composite design of the block also provides a reduction in material costs during
manufacture of block. In addition, the molding of paper pulp is easier from a technological
point of view than the casting of large monolithic blocks, which improves the manufacturability
of blocks.
[0036] The manufacturing process of building blocks is also more environmentally friendly
compared to casting of monolithic plastic blocks.
[0037] Therefore, the building blocks require less volume during their storage and transportation,
reduce material consumption and increase manufacturability.
[0038] Moreover, building blocks are safe for use as children's toys even with large sizes
of blocks, and the manufacturing process of construction toy details provides high
environmental security.
Industrial applicability
[0039] Building blocks can be made from molded paper obtained from waste paper by casting.
