Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to an assembly
structure for a building block, such as Lego bricks and Mega Bloks
bricks, and more particularly to provide an assembly structure of a
building block allowed to be engaged with a secondary main body of
an additional building block from various directions of
circumferences and generating the encasing and decorating effects,
and especially to provide an assembly structure of a building block
having connection surfaces of a main body to be connected with a
secondary main body of an additional building block and studs to be
engaged with an engaging recess of the secondary main body of the
additional building block.
[0003] 2. The Prior Arts
[0004] Building blocks are toys that can train hand eye
coordination, enhance the development of intelligence and develop
children's imagination and creativity. Therefore, the building
blocks are popular and widely favored by the consumers.
[0005] Currently, the most successful construction toy in the world
is generally considered to be the Lego bricks, which are
manufactured by The Lego Group, a company having a history of 50
years and based in Denmark. The Lego Group not only has the most
customers and the largest market share in the world but also has
the largest forum, creators and players. Therefore, Lego become a
synonym for the building blocks.
[0006] Because many patents of Lego expire, a lot of toy companies
manufacturing the building blocks, such as Mega Bloks based in
Canada, adopt the interlocking structure of studs and engaging
recesses of Lego bricks. Thus, the building blocks manufactured by
the competing companies have designs, structures, and interlocking
structure very similar to the Lego bricks.
[0007] There are unlimited and various ways to play the building
blocks. The building blocks have various shapes, such as a square,
a rectangle, a triangle, a cylinder, etc. and have variety of
colors. Thus, the children can connect the building blocks having
various shapes, sizes and colors, thereby developing children's
imagination and creativity and providing entertainment.
[0008] The interlocking structure of the conventional building
blocks is stacking them in the vertical direction. Thus, a main
body and a secondary main body of the building block include one or
more than one studs disposed at tops thereof and the studs are
arranged evenly spaced. Moreover, the main body and the secondary
main body include at least one engaging recess disposed at a bottom
thereof. The engaging recesses can be engaged with the studs with
interference fit. The main body of the building block can be
engaged with the engaging recesses of the secondary main body of
the additional building block by the studs or can be engaged with
the studs of the secondary main body of the additional building
block by the engaging recesses. Therefore, the connection surfaces
are formed on a top and a bottom of the main body to be connected
with the secondary main body of the additional building block,
respectively.
[0009] Furthermore, in order to enhance the appearance of the
connected building blocks, the Lego Group and Mega Bloks also
market a building block having a decoration surface, and the
decoration surface is shaped in a smooth, curved or special contour
to reduce or omit the studs of the building block. The decoration
surface is formed at a side of the building block opposite to the
engaging recess and this type of building block takes advantage of
the engaging recesses to be assembled to the most exterior of the
connected building blocks. Thus, the decoration surface is exposed
to the most exterior and encases the studs inside to enhance the
appearance.
[0010] Based on the design of the engaging recess, each main body
of the building block includes both of the studs to be engaged with
the engaging recess of the secondary main body of the additional
building block and the engaging recess to be engaged with the studs
of the secondary main body of the additional building block. For a
long time, manufacturers of Lego bricks, Mega Bloks bricks or the
other building blocks all follow this principle to change and
design the main bodies and the secondary main bodies of the
building blocks. Even though the studs are replaced by the
decoration surfaces as mentioned above, the engaging recess is
still the common design of the main bodies and the secondary main
bodies of the building blocks.
[0011] Obviously, the main body and the secondary main body having
the engaging recesses save the cost of the manufacturing material
more than the main body and the secondary main body having the
studs. However, it greatly limits the feasibility during assembling
the building blocks. Because the existence of the engaging recess,
it is unable to directly engage the engaging recess of the main
body with the engaging recess of the secondary main body of the
building block having the decoration surface. Therefore, after the
building blocks are assembled, the engaging recess would likely be
exposed at the back of the assembled building blocks. Thus, the
aesthetic appearance of the building blocks deteriorates and it is
inconvenient to assemble the building blocks. It needs to solve
this problem of the conventional building blocks.
[0012] In addition, if other building blocks are provided between
the engaging recess of the main body and the engaging recess of the
secondary main body of the building block having the decoration
surface to connect them together, it would make the connected
building blocks thicker and bulkier. Moreover, the building block
has its own thickness. When assembling the automobiles, the
airplanes, the ships, the robots, and so on that have specific
proportions, the extra building blocks provided between the
originally needed building blocks would change the proportions. The
overall aesthetic appearance of the assembled building blocks
deteriorates. And, it is also inconvenient to assemble the building
blocks in this way.
[0013] Based on the aforementioned descriptions, the applicant
proposes the present invention that overcomes the disadvantages of
the conventional building blocks.
SUMMARY OF THE INVENTION
[0014] A primary objective of the present invention is to provide
an assembly structure of a building block, and particular to an
assembly structure of a building block allowed to be engaged with a
secondary main body of an additional building block from various
directions of circumferences and generating the encasing and
decorating effects. Because the main body of the conventional
building block includes an engaging recess, it is unable to
directly engage the engaging recess of the main body with the
engaging recess of the main body of the building block having the
decoration surface. Therefore, after the building blocks are
assembled, the engaging recess would be exposed at the back of the
assembled building blocks. Thus, the aesthetic appearance of the
building blocks deteriorates and it is inconvenient to assemble the
building blocks. The objective of the present invention is to
provide an assembly structure of a building block to overcome the
shortcomings of the conventional designs.
[0015] In order to achieve the objective, an assembly structure of
a building block according to the present invention includes a main
body. An exterior of the main body includes a plurality of
connection surfaces facing toward the various directions of the
circumferences of the main body, respectively.
[0016] Each of the connection surfaces includes at least one stud
extended outward to be connected with the secondary main body of
the additional building block. The secondary main body of the
additional building block includes an engaging recess to be engaged
with the stud of the main body.
[0017] Based on the structure mentioned above, the studs face
toward the various directions of the circumferences of the main
body, respectively, and therefore the studs of the main body can be
engaged with the secondary main bodies of the additional building
blocks from various directions of the main body of the building
block.
[0018] The embodiments of the present invention is further
explained in the following descriptions:
[0019] According to the primary structural feature mentioned above,
the secondary main body is provided with a decoration surface
disposed at a side corresponding to be away from the main body.
[0020] According to the primary structural feature mentioned above,
the secondary main body is provided with at least one stud disposed
at a side corresponding to be away from the main body.
[0021] According to the primary structural feature mentioned above,
the main body includes a polyhedron. The polyhedron can be a
hexahedron.
[0022] According to the primary structural feature mentioned above,
the main body includes a recess defined therein, and the recess is
defined in at least one connection surface. The studs of the main
body are formed by extending from an inner wall of the bottom of
the recess.
[0023] Compared with the conventional building block, the present
invention includes the following advantages:
[0024] 1. The main body of the building block according to the
present invention omits the engaging recess and includes the studs
disposed on all side walls of the main body. Moreover, the studs
disposed on the connection surfaces are extended toward various
directions of the circumferences of the main body, which makes the
studs easy to be engaged with the engaging recesses of the
secondary main bodies of the additional building blocks from
various directions of the circumferences. Thus, the main body of
the building block according to the present invention enhances the
feasibility and convenience when assembling the building
blocks.
[0025] 2. Because the studs are disposed on all of the side walls
of the main body, all of the connection surfaces of the main body
can be directly engaged with the engaging recess of the secondary
main body of the additional building block having the decoration
surface. Therefore, all of the side walls and studs of the main
body can be encased in the decoration surfaces without increasing
the thickness or changing the proportions. Furthermore, the overall
aesthetic appearance of the assembled building blocks according to
the present invention is improved.
[0026] 3. The main bodies according to the present invention can
use studs distributed on all side walls thereof to be connected
with the secondary main bodies of the conventional additional
building blocks. There are huge numbers of additional building
blocks that have the studs, the decoration surfaces or various
designs currently available. Therefore, the assembly structure of
the building block according to the preferred embodiment makes the
assembling ways of the building blocks more diverse, and greatly
improves the variability of the appearances and designs of the
conventional building blocks.
[0027] Based on the descriptions mentioned above, the applicant
provides the present invention that overcomes the disadvantages of
the conventional building blocks.

body 1 is provided with a plurality of connection surfaces 12 to be
connected with secondary main bodies 2 of additional building
blocks (as shown in FIGS. 8 and 9). The connection surfaces 12 face
toward various directions of the circumferences of the main body 1,
respectively. The various directions of the circumferences of the
main body 1 include six directions, the top, bottom, left, right,
front and rear directions of the main body 1.
[0041] The connection surfaces 12 are disposed on all of outer
walls, including the top, bottom, left, right, front and rear outer
walls of the main body 1. Each of the connection surfaces 12
includes at least one stud 11 extended outward to be connected with
the secondary main body 2 of the additional building block. The
secondary main body 2 of the additional building block includes an
engaging recess 20 corresponding to the stud 11 of the main body 1,
so that the engaging recess 20 of the secondary main body 2 can be
engaged with the stud 11 of the main body 1. The studs 11 face
toward various directions of the circumferences of the main body 1,
respectively, and therefore the studs 11 of the main body 1 can be
engaged with the secondary main bodies 2 of the additional building
blocks from the top, bottom, left, right, front and rear directions
of the main body 1.
[0042] FIGS. 4 to 6 show further preferred embodiments of the
present invention. FIG. 4 is a perspective view showing an assembly
structure of a building block according to the second embodiment
that is a variation of the assembly structure of FIG. 1. FIG. 5 is
a perspective view showing the assembly structure of the building
block of FIG. 4 from a bottom viewing angle. FIG. 6 is a
perspective view showing an assembly structure of a building block
according to a third embodiment that is another variation of the
assembly structure of the building block of FIG. 1. Each of the
connection surfaces 12a, 12b of the main body 1a, 1b include more
than one stud 11a, 11b that are arranged evenly spaced. The studs
11a, 11b can be arranged in a single row or arranged as a
matrix.
[0043] FIGS. 7 to 9 show another preferred embodiment of the
present invention. FIG. 7 is a perspective view showing the
assembly structure of the building block of FIG. 6 in use. FIG. 8
is a partially exploded view showing the assembly structure of the
building block of FIG. 7. FIG. 9 is an exploded view showing the
assembly structure of the building block of FIG. 8. The present
invention further includes:
[0044] According to the preferred embodiments, a position of the
secondary main body 2 of the additional building block
corresponding to the connection surface 12, 12a, 12b of the main
body 1, 1a, 1b includes the engaging recess 20 provided to be
engaged with the stud 11, 11a, 11b of the main body 1, 1a, 1b.
[0045] According to the preferred embodiments, the secondary main
body 2 of the additional building block includes a decoration
surface 22 disposed at a side corresponding to be away from the
connection surface 12, 12a, 12b of the main body 1, 1a, 1b. Thus,
the decoration surface 22 accompanying with the secondary main body
2 of the additional building block encases the connection surface
12, 12a, 12b of the main body 1, 1a, 1b. And, the decoration
surface 22 can have a smooth, curve or special shape.
[0046] According to the preferred embodiments, the secondary main
body 2 of the additional building block includes a stud 21 disposed
at a side corresponding to be away from the connection surface 12,
12a, 12b of the main body 1, 1a, 1b. The stud 21 of the secondary
main body 2 of the additional building block can be engaged with
the engaging recess 20a of the secondary main body 2a of another
additional building block.
[0047] In fact, the secondary main body 2, 2a of the additional
building block can be conventional Lego or Mega Bloks bricks.
[0048] According to the preferred embodiments, the main body 1, 1a,
1b of the building block can be a polyhedron. The polyhedron
includes a brick of a pentahedron, a hexahedron, a heptahedron,
etc. In other words, the polyhedron is a brick having a square,
rectangular, triangle or trapezoid surface. According to the
preferred embodiments of the present invention, the main body 1,
1a, 1b is a parallelepiped.
[0049] According to the preferred embodiments, the main body 1, 1a,
1b includes a recess 10, 10a, 10b defined therein, and the recess
10, 10a, 10b is disposed in at least one connection surface 13,
13a, 13b. The studs 11, 11a, 11b of the connection surface 13, 13a,
13b is formed by extending from an inner wall of the bottom of the
recess 10, 10a, 10b.
[0050] In fact, the structure of the recess 10, 10a, 10b of the
connection surface 13, 13a, 13b of the main body 1, 1a, 1b is
equivalent to that of the engaging recess 20, 20a of the secondary
main body 2, 2a of the additional building block. However, the stud
11, 11a, 11b of the connection surface 13, 13a, 13b of the main
body 1, 1a, 1b is extended from the inner wall of the recess 10,
10a, 10b, so that the recess 10, 10a, 10b of the main body 1, 1a,
1b according to the present invention excludes the original
function of the engaging recess. In the mean time, the studs 11,
11a, 11b extend toward various directions of the circumferences of
the main body 1, 1a, 1b, respectively, and are capable of being
engaged with the engaging recesses 20 of the secondary main bodies
2 of the additional building blocks from various directions of the
circumferences of the main body 1, 1a, 1b. Therefore, the assembly
structure of the building block according to the present invention
possesses inventive step.
[0051] The secondary main body 2 of the additional building block,
such as the conventional Lego or Mega Bloks bricks, is usually
provided with the engaging recess 20 at a side opposite to the
decoration surface 22. The engaging recess 20 increases the
strength of the secondary main body 2 and prevents size deviation
caused by shrinking deformation after injection molding. Thus, it
ensures the fulfillment of quality requirement and it also reduces
the cost of the materials. Of course, the secondary main body of
the conventional building block may also be provided with the studs
at a side opposite to the decoration surface, but it is a special
product whose amount and designs are far fewer than the secondary
main body 2 of the additional building block having the engaging
recess 20 at a side opposite to the decoration surface 22.
[0052] Therefore, the main body 1, 1a, 1b includes studs 11, 11a,
11b disposed on all connection surfaces 12, 13, 12a, 13a, 12b, 13b,
which are the top, bottom, left, right, front and rear outer walls
of the main body 1, 1a, 1b, and extended toward various directions
of the circumferences of the main body 1, 1a, 1b. Therefore, the
main body 1, 1a, 1b according to the present invention can directly
engaged with the aforementioned secondary main body 2 having the
engaging recess 20 disposed on the side opposite to the decoration
surface 22 and the aforementioned secondary main body 2 having the
engaging recess 20 disposed on the side opposite to the stud 21.
Therefore, it is very convenient to assemble the main body 1, 1a,
1b of the building block according to the present invention with
the secondary main body 2 of the conventional additional building
block.
[0053] Through the structure mentioned above, it can carry out the
present invention. The following description takes the main body 1b
to assemble a robot as an example to further explain the present
invention. FIGS. 7 and 8 clearly show using the main body 1b
according to the present invention to assemble an upper portion of
a robot.
[0054] The main body 1b can be used to assemble a backpack assembly
of the robot. A torso and a head of the robot are assembled by the
secondary main bodies 2b of the additional building blocks, and the
conventional engaging recesses (not shown in the drawings) are
exposed at a back of the robot. Because the secondary main bodies
2b assembled to form the upper portion of the robot are
conventional Lego or Mega Bloks bricks and the chest and the face
of the robot are presented by the decoration surfaces 22b, the user
can freely connect the secondary main bodies 2b of the additional
building blocks and arrange them to expose the engaging recesses
22b at the back of the robot.
[0055] Then, taking the main body 1b as a center, the engaging
recesses 20, 20b, 20c, 20d, 20e, 20f of the secondary main bodies
2, 2b, 2c, 2d, 2e 2f surround and engage with the studs 11b of the
all connection surfaces 12b, 13b of the main body 1b according to
the present invention. Because the studs 11b disposed at the side
walls of the main body 1b are engaged with the secondary main
bodies 2, 2c, 2d, 2e, 2f of the additional building blocks, the
decoration surfaces 22, 22c, 22d, 22e, 22f encase the
circumferences of the studs 11b of the connection surfaces 12b, 13b
of the main body 1b and show the appearance of the backpack of the
robot. Because the studs 11b of the main body 1b are further
engaged with the secondary main body 2b of the additional building
blocks, the backpack is connected to the back of the robot. Thus,
the assembly of the upper portion of the robot is finished.
[0056] As mentioned above, the main body 1 of the building block
according to the present invention omits the engaging recess of the
conventional Lego and Mega Bloks bricks and is provided with the
studs 11, 11a, 11b disposed on all side walls of the main body 1,
1a, 1b. Moreover, the studs 11, 11a, 11b disposed on the connection
surfaces 12, 13, 12a, 13a, 12b, 13b are extended toward various
directions of the circumferences of the main body 1, 1a, 1b, which
makes the studs 11, 11a, 11b easy to engaged with the engaging
recesses 20, 20b, 20c, 20d, 20e or 20f of the secondary main body
2, 2b, 2c, 2d, 2e or 2f from various directions of the
circumferences. Furthermore, the secondary main body 2, 2b, 2c, 2d,
2e, 2f of the additional building block can use the studs 21 or the
engaging recesses thereof to connect with the other additional
building blocks. Therefore, the main bodies 1, 1a, 1b of the
building blocks and the secondary main bodies 2, 2a, 2b, 2c, 2d, 2e
and 2f of the additional building blocks can be connected to form
the buildings, the automobiles, the airplanes, the ships, the
robots or other objects. Thus, the main body 1 of the building
block according to the present invention enhances the diversity and
convenience when assembling the building blocks.
[0057] It is noticeable that the studs 11, 11a, 11b are disposed on
all of the side walls of the main body 1, 1a, 1b. Thus, all of the
connection surfaces 12, 13, 12a, 13a, 12b, 13b of the main body 1,
1a, 1b can take advantage of the studs 11, 11a, 11b thereof to be
directly engaged with the engaging recesses 20, 20b, 20c, 20d, 20e,
20f of the secondary main body 2, 2b, 2c, 2d, 2e, 2f of the
conventional additional building block having the decoration
surface 22, 22b, 22c, 22d, 22e, 22f. Therefore, all of the side
walls and studs 11, 11a, 11b of the main body 1, 1a, 1b can be
wrapped in the decoration surfaces 22, 22b, 22c, 22d, 22e, 22f, and
then the secondary main bodies 2, 2b, 2c, 2d, 2e, 2f can further
connect with the secondary main bodies of the other additional
building blocks. The overall aesthetic appearance of the assembled
building blocks according to the present invention can be enhanced
without increasing the thickness or changing the proportions.
[0058] Accordingly, the main bodies 1, 1a, 1b according to the
present invention can use studs 11, 11a 11b distributed on all side
walls to connected with the secondary main bodies 2, 2a, 2b, 2c,
2d, 2e, 2f of the conventional additional building blocks. There
are huge number of additional building blocks currently available,
such as additional building blocks 2, 2a, 2b, 2c, 2d, 2e, 2f having
studs 21 and the decoration surfaces 22, 22a, 22b, 22c, 22d, 22e,
22f or various designs. Therefore, the assembly structure of the
building block according to the preferred embodiment makes the
assembling ways of the building blocks more diverse, and greatly
improves the variability of the appearances and designs of the
conventional building blocks.
[0059] In summary, because the main body of the conventional
building block includes the engaging recess, it is unable to
directly engage the engaging recess of the main body with the
engaging recess of the main body of the building block having the
decoration surface. Therefore, after the building blocks are
assembled, the engaging recess would be exposed at the back of the
assembled building blocks. Thus, the aesthetic appearance of the
building blocks deteriorates and it is inconvenient to assemble the
building blocks. The assembly structure of the building block
according to the present invention does overcome the shortcomings
of the conventional building blocks mentioned above, and can
engaged with the main bodies of the additional building blocks in
every direction to provide the effect of encasing and
decoration.
[0060] Although the present invention and its using methods have
been described with reference to the preferred embodiments thereof,
it is apparent to those skilled in the art that a variety of
modifications and changes may be made without departing from the
scope of the present invention which is intended to be defined by
the appended claims.
