Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority of Chinese patent
application No. 201910730188.8, filed on Aug. 8, 2019, which is
incorporated herewith by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The invention relates to a building block, in particular to
a building block having a light-emitting element disposed therein.
The light emitted from the light-emitting element can pass through
the main body of the building block and make the building block
have a light-emitting effect.
2. The Prior Arts
[0003] The conventional jigsaw puzzles use a plurality of small
interlocking units to form a complete pattern. In particular, each
of interlocking units has a unique shape such that each side of the
interlocking units can only be connected with another specific
interlocking unit. Thereby, the user can gradually connect the
interlocking units with each other to produce a large complex
pattern by trial and error. However, although the interconnection
of the interlocking units of the jigsaw puzzles is advantageous for
the user to connect to form a complex pattern, it also limits the
possibility for the user to use the interlocking units to form
different patterns. The conventional jigsaw puzzles can only form a
single pattern, which lacks variability in use.
[0004] In addition, some manufacturers have developed a
light-emitting building block assembly. The light-emitting building
blocks in the light-emitting building block assembly can be
assembled and connected in many ways to construct objects having
light and shadow effects, and the light-emitting building block
assembly allows for the construction of a variety of different
shapes and models by changing the interconnection relationship
between the light-emitting building blocks. However, the light and
shadow effect of the convention light-emitting building blocks
cannot form letters or patterns. Thus, the functions of the
light-emitting building blocks are not perfect.
[0005] Therefore, the jigsaw puzzles and light-emitting building
blocks available on the market still need to be improved to solve
the existing problems.
SUMMARY OF THE INVENTION
[0006] To overcome the disadvantages of conventional designs, a
primary objective of the present invention is to provide a puzzle
building block capable of changing light-emitting areas and a
puzzle building block assembly so that the light-emitting blocks
can be used to form planar letters or patterns.
[0007] In order to achieve the primary objective, a puzzle building
block that can change a light-emitting area, including: a building
block board including a plate body and a plurality of connection
portions, the plate body including a top surface and a bottom
surface respectively disposed at two opposite sides of the plate
body, the connection portions being disposed on the top surface of
the plate body; a circuit board disposed adjacent to the bottom
surface of the building block board; a plurality of light-emitting
elements disposed on a side of the circuit board facing the
building block board, and light emitted from each of the
light-emitting elements passing through the building block board
via the connection portions; and a plurality of building bricks, a
side of each of the building bricks being formed with a fitting
portion, the fitting portions being selectively fitted with the
corresponding connection portions of the building block board,
wherein the connection portions are selectively shielded by the
building bricks such that the light emitted from the light-emitting
elements produces a light-and-dark difference on a top surface of
the building block board.
[0008] Preferably, the puzzle building block capable of changing
the light-emitting areas of the present invention includes a
building block board, and the top surface of the building block
board is formed with the plurality of connection portions. The
light emitted from the light-emitting elements passes through the
connection portions such that the building block board shows a
large area of illumination when it is not fitted with the building
bricks.
[0009] Preferably, the building brick of the present invention may
be an opaque building brick, but may also be a transparent or
single-color light-transmitting building brick. Meanwhile, the
light-emitting elements corresponding to the connection portions
may also be color light-emitting elements such that there are color
differences between the respective connection portions. When the
puzzle building block according to the present invention is in use,
the user fits the building bricks with the connection portions of
the building block board. When the connection portions of the
building block board are fitted with the opaque building bricks, a
light-and-dark difference is produces between the connection
portions fitted with the opaque building bricks and the other
connection portions. When the connection portions of the building
block board are fitted with the light-transmitting building bricks,
a color difference is produced between the connection portions
fitted with the light-transmitting building bricks and the other
connection portions by the colors of the light-transmitting
building bricks or by the colors of the light emitted from the
light-emitting elements.
[0010] The advantages of the present invention lies in that the
light emitted from the light-emitting elements can produce a
light-and-dark difference or a color difference on a side of the
building block board to form letters or patterns by mounting the
building bricks on the respective connection portions of the
building block board. Moreover, the light emitted from the
light-emitting elements can form various letters or patterns on the
side of the building block board by changing the mounting positions
of the building bricks.
[0011] In order to achieve the foregoing objective, the present
invention further provides a puzzle building block assembly,
comprising a plurality of the above-mentioned puzzle building
blocks capable of changing light-emitting areas, and sides of
adjacent two of the puzzle building blocks capable of changing
light-emitting areas are connected with each other, and the
adjacent two of the puzzle building blocks capable of changing
light-emitting areas are electrically connected with each
other.
[0012] The puzzle building block assembly of the present invention
has the advantage that the sides of the plurality of puzzle
building blocks capable of changing light-emitting areas are
pressed against each other and the top surfaces of the puzzle
building blocks are flush after the connection. Therefore, the user
can connect the plurality of puzzle building blocks capable of
changing light-emitting areas to form a large-area of puzzle
building block assembly to construct a more complex pattern. At the
same time, the circuit boards of the puzzle building blocks capable
of changing the light-emitting areas are electrically connected to
each other. When the puzzle building block assembly is in use, it
only needs to connect one of the puzzle building blocks capable of
changing the light-emitting areas to the power source such that all
of the puzzle building blocks can be illuminated. It is more
convenient to use.
[0013] Further, the positions of the light-emitting elements
correspond to those of the connection portions.
[0014] Further, the building brick includes a light-shielding
building brick, and the fitting portion of the light-shielding
building brick is a first fitting portion.
[0015] Further, the building brick further includes a
light-transmitting building brick, and the fitting portion on the
light-transmitting building brick is a second fitting portion.
[0016] Further, the building block board is made of a
light-transmitting material.
[0017] Further, the building block board is made of an opaque
material, and the connection portion of the building block board
includes a light guide hole passing through the building block
board.
[0018] Further, the plate body is made of an opaque material. The

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0029] Embodiments of the present invention will now be described
with reference to the drawings, in which like reference numerals
represent like elements.
[0030] Referring to FIGS. 1 to 3, a puzzle building block capable
of changing light-emitting area according to a first embodiment of
the present invention includes a building block board 10, a circuit
board 20, a plurality of light-emitting elements 30, a plurality of
light-shielding building bricks 40, and a plurality of
light-transmitting building bricks 50.
[0031] The building block board 10 includes a plate body 11 and a
plurality of connection portions 12. The opposite two sides of the
plate body 11 are a top surface 111 and a bottom surface 112,
respectively. The connection portions 12 are disposed on the top
surface 111 of the plate body 11. According to the first
embodiment, the connection portions 12 are arranged in a matrix and
distributed all over the top surface 111 of the building block
board 10.
[0032] The circuit board 20 is disposed adjacent to the bottom
surface 112 of the building block board 10. According to the first
embodiment, a mounting circumferential wall is projected from the
bottom surface 112 of the building block board 10 to surround the
periphery of the bottom surface 112, and the circuit board 20 abuts
against the inner side surface of the mounting circumferential wall
of the building block board 10. That is, the circuit board 20 is
received in the building block board 10, but the configuration is
not limited thereto.
[0033] The light-emitting elements 30 are disposed on a top surface
of the circuit board 20 facing the building block board 10.
According to the first embodiment, the positions of the
light-emitting elements 30 are the same as the positions of the
connection portions 12. That is, the positions of the
light-emitting elements 30 overlap with the positions of the
connection portions 12 when viewed from the top surface 111 of the
building block board 10. The light emitted from each of the
light-emitting elements 30 passes through the building block board
10 via the corresponding connection portions 12, but the positions
of the light-emitting elements 30 and the positions of the
connection portions 12 are not limited to the same locations. The
positions of the light-emitting elements 30 can also correspond to
the positions of the connection portions 12 in other ways, as long
as the light emitted from the light-emitting elements 30 can pass
through the building block board 10 via the connection portion 12.
The light-emitting elements 30 are electrically connected with each
other.
[0034] The building block board 10 according to the first
embodiment is made of, but not limited to, a light-transmitting
material such that the light emitted from the light-emitting
elements 30 can pass through the building block board 10 via the
connection portions 12. In the following description, the present
invention further provides two embodiments in which the light
emitted from the light-emitting elements 30 can also pass through
the building block board 10 via the connection portions 12.
[0035] Referring to FIG. 4, the building block board 10A according
to a second embodiment of the present invention is made of an
opaque material, and each connection portion 12A is provided with a
light guide hole 121A passing therethrough. When the building block
board 10A is not engaged with any of the light-shielding building
bricks 40A, the illumination of the building block board 10A is the
multi-point illumination from the connection portions 12A instead
of the full-surface illumination from the whole building block
board 10A according to the first embodiment.
[0036] Referring to FIG. 5, the plate body 11B of the building
block board 10B according to a third embodiment of the present
invention is made of an opaque material. The plate body 11B
includes a plurality of through holes 113B, and the through holes
113B extend to the top surface 111B and the bottom surface 112B of
the plate body 11B. The connection portions 12B made of a
light-transmitting material are respectively received in the
through holes 113B such that the way of illumination can be the
same as that of the second embodiment. According to the third
embodiment, an end of the connection portion 12B facing the circuit
board 20B is aligned with, but not limited to, the bottom surface
112B of the building block board 10B. The end of connection portion
12B facing the circuit board 20B may also protrude out of or
retract inside of the bottom surface 112B of the building block
board 10B.
[0037] Referring back to FIG. 1 to FIG. 3, the light-shielding
building brick 40 according to the first embodiment of the present
invention can be fitted with the connection portion 12 of the
building block board 10. Specifically, one side of the
light-shielding building brick 40 is formed with a first fitting
portion 41 as shown in FIG. 3, and the first fitting portion 41 can
be fitted with the connection portion 12 of the building block
board 10. When the light-shielding building brick 40 is fitted with
one of the connection portions 12 of the building block board 10,
the light-shielding building brick 40 shields the connection
portion 12. That is, when the light-shielding building brick 40 is
fitted with and mounted on the connection portion 12, the
light-shielding building brick 40 blocks the light emitted from the
light-emitting element 30 from passing through the connection
portion 12, thereby making the light emitted from the
light-emitting element 30 produce a light-and-dark difference on
the top surface 111 of the building block board 10. When a
plurality of light-shielding building bricks 40 are fitted with and
mounted on appropriate positions of the building block board 10,
the light-shielding building bricks 40 can be arranged to form
letters or patterns. Then, the light emitted from the
light-emitting elements 30 can form the light-and-dark difference
on the top surface 111 of the building block board 10, and form the
letters or patterns by the light-and-dark difference.
[0038] The light-transmitting building brick 50 can be fitted with
the connection portion 12 of the building block board 10.
Specifically, one side of the light-transmitting building brick 50
is formed with a second fitting portion 51 as shown in FIG. 3, and
the second fitting portion 51 can be fitted with the connection
portion 12 of the building block board 10. Furthermore, the shape
of the second fitting portion 51 is the same as the shape of the
connection portion 12 of the light-shielding building bricks 40.
Each of the light-transmitting building bricks 50 can be made of a
material with a single color. Moreover, the light-transmitting
building bricks 50 according to another preferred embodiment may
have at least two different colors. Thereby, the pattern formed by
puzzle building block according to the present invention can
further provide color differences in addition to the light-and-dark
difference by using the light-transmitting building bricks 50
having different colors. Further, each of the light-emitting
elements 30 according to the present invention can also be a color
light-emitting element 30. The light-emitting element 30 can
respectively emit light of different colors, such that the
respective connection portions 12 on the building block board 10
can exhibit various light and shadow effects by the color
differences of the respective light-emitting elements 30.
[0039] According to the present embodiment, the sum of the number
of the light-transmitting building bricks 50 and the number of the
light-shielding building bricks 40 are equal to the number of the
connection portions 12. That is, the connection portions 12 are
arranged in a matrix and distributed all over the top surface 111
of the building block board 10. The light-shielding building bricks
40 are mounted on part of the connection portions 12 on the
building block board 10 to form the letters or patterns, and the
light-transmitting building brick 50 is mounted on the connection
portions 12 on which the light-shielding building bricks 40 are not
mounted.
[0040] According to the present embodiment, the connection portions
12 are cylinders protruded from the top surface of the building
block board 10, and the first fitting portions 41 and the second
fitting portions 51 are circular recesses defined in the building
bricks. The shapes of the connection portions and the fitting
portions are not limited to the cylinder and the circular recesses,
as long as the connection portions 12 can be fitted with the first
fitting portion 41 and the second fitting portion 51. For example,
the connection portion 12 may be a square recess defined in the
building block board 10, the first fitting portion 41 and the
second fitting portion 51 are square columns, and the first fitting
portion 41 and the second fitting portion 51 may be fitted with the
connection portion 12.
[0041] Referring to FIG. 6, the puzzle building block capable of
changing light-emitting areas according to a fourth embodiment of
the present invention is substantially the same as the one
according to the first embodiment. The difference between the
fourth embodiment and the first embodiment is in that the fourth
embodiment does not have any light-transmitting building brick but
only has the light-shielding building bricks 40C, thereby arranging
to form letters or patterns. According to the present embodiment,
part of the connection portions 12C are not fitted with the
light-shielding building bricks 40C, and the light emitted from the
light-emitting elements 30C can pass through these connection
portions 12C. The connection portions 12C without being fitted with
the light-shielding building bricks 40C and connection portions 12C
fitted with the light-shielding building bricks 40C then form
patterns by creating a light-and-dark difference, but not limited
thereto. According to another preferred embodiment of the present
invention, the light-shielding building bricks 40C may be replaced
by the light-transmitting building bricks, and a color of the
light-transmitting building brick is different from that of the
light-emitting element 30C. After the connection portion 12C is
fitted with the light-transmitting building brick, the connection
portion 12C is covered by the light-transmitting building brick.
The color of the light emitted from the light-emitting element 30C
changes after passing through the connection portion 12C and the
light-transmitting building brick covering the connection portion
12C. Therefore, the light emitted from the light-emitting element
30C have color differences on the top surface 111C of the building
block board 10C, and letters or patterns are formed by the color
differences.
[0042] Referring to FIG. 7, the puzzle building block capable of
changing light-emitting areas according to a fifth embodiment of
the present invention is substantially the same as the one
according to the first embodiment. The difference between the fifth
embodiment and the first embodiment is in that the connection
portions 12D of the building block board 10D are arranged on the
top surface 111D of the building block board 10D to form letters or
patterns. Furthermore, according to the fifth embodiment, there is
no light-shielding building brick, but there are only the
light-transmitting building bricks 50D. The number of the
light-transmitting building bricks 50D is the same as the number of
the connection portions 12D. That is, all of the connection
portions 12D can be fitted with the light-transmitting building
bricks 50D. When the puzzle building block according to the fifth
embodiment is in use, the light-transmitting building bricks 50D
are respectively fitted with the connection portions 12D such that
the shapes of the letters or patterns formed by the arranged
light-transmitting building bricks 50D are exactly the same as
those of the letters or patterns formed by the connection portions
12D. However, the color of the letters or patterns are converted
from the color of the light-emitting elements 30D to the color of
the light-transmitting building bricks 50D. The user can easily
mount the light-transmitting building bricks 50D onto the building
block board 10D one by one and the light-transmitting building
bricks 50D can automatically form the letters or patterns, which is
more convenient to use, but not limited thereto. The present
embodiment can also have the following variations:
[0043] First, the light-emitting element 30D may be a color
light-emitting element, such as a three-color LED, and therefore
the color light-emitting element 30D can directly make the
respective connection portions 12D display in different colors.
Thus, the letters or patterns presented according to the present
embodiment can have color differences, and show various light and
shadow effects, such as contours or shadows.
[0044] Secondly, each of the light-transmitting building bricks 50D
are made of a material with a single color and have at least two
different colors, thereby further enhancing the color differences
for the letters or patterns formed by the arranged
light-transmitting building bricks 50D and showing various light
and shadow effects, such as contours or shadows.
[0045] Thirdly, it may further include a light-shielding building
brick, and the light-shielding building brick can be fitted with
the connection portions 12D. The number of the light-shielding
building bricks fitted with the connection portions 12D is less
than the number of the connection portions 12D. Therefore, part of
the connection portions 12D can be shielded by the light-shielding
building bricks. Then, the remaining unshielded connection portions
12D form new letters or patterns, and the new letters or patterns
are different from those formed by all of the connection portions
12D. For example, according to an embodiment, all of the connection
portions 12D are arranged in the Arabic numeral "8". After part of
the connection portions 12D are fitted with the light-shielding
building bricks, the unshielded connection portions show the Arabic
numeral "0". Then, the light-transmitting building bricks 50D may
further be fitted with the unshielded connection portions 12D such
that the light-transmitting building bricks 50D show the
aforementioned Arabic numeral "0". Because part of the light
emitted from the light-emitting elements 30D is blocked by the
light-shielding building bricks, a light-and-dark difference is
generated on the top surface 111D of the building block board 10D
to form the letters or patterns
[0046] Fourthly, there may be only a light-shielding building
bricks but without any light-transmitting building brick 50D. The
light-shielding building bricks are fitted with part of the
connection portions 12D to provide the shielding such that the
remaining unshielded connection portions 12D form new letters or
patterns. The specific method is the same as the one described in
the foregoing description and will not be repeatedly described
here.
[0047] Fifthly, regarding how the light emitted from the
light-emitting elements 30D passing through the building block
board 10D, it may also have variations as the second or third
embodiment described above. That is, the light emitted from the
light-emitting elements 30D passes through the light guide holes of
the connection portions 12D as the second embodiment, or the light
emitted from the light-emitting elements 30D passes through the
connection portions 12D made of the light-transmitting material as
the third embodiment. The specific implementations have been
described in the foregoing second and third embodiments, and will
not be repeatedly described here.
[0048] Referring to FIGS. 1 and 2, when the puzzle building blocks
capable of changing light-emitting areas according to the first
embodiment of the present invention are in use, the circuit board
20 of the puzzle building block capable of changing light-emitting
area is connected to the power source such that all of the
light-emitting elements 30 emit light. Then, the user can fit the
light-shielding building bricks 40 and the light-transmitting
building bricks 50 with the connection portions 12 on the building
block board 10 so that the light-shielding building bricks 40 are
arranged to form the letters or patterns. The puzzle building block
capable of changing light-emitting areas according to other
embodiments of the present invention can use the light-transmitting
building bricks 50 and/or the light-shielded building bricks 40 to
form the letters or patterns as appropriate.
[0049] Referring to FIG. 8, a puzzle building block assembly
according to the present invention includes a plurality of puzzle
building blocks capable of changing light-emitting areas according
to the first embodiment of the present invention, but not limited
thereto. The puzzle building block assembly may also include the
puzzle building blocks capable of changing light-emitting areas
according to one or more of the embodiments. The sides of the
puzzle building blocks capable of changing light-emitting areas are
pressed against each other and the top surfaces 111 of the puzzle
building blocks are flush, thereby expanding the area of the puzzle
building block assembly. Therefore, the puzzle building block
assembly can provide the patterns or letters in more detail.
[0050] The circuit boards 20 of the puzzle building blocks capable
of changing light-emitting areas of the puzzle building block
assembly are electrically connected with each other. Therefore,
when the puzzle building block assembly is in use, it only needs to
connect one of the circuit boards 20 among the puzzle building
blocks capable of changing light-emitting areas with the power
source. Then, all of the light-emitting elements 30 of the puzzle
building blocks capable of changing light-emitting areas can be
powered to illuminate. The puzzle building block assembly according
to the present embodiment includes a plurality of conductive
cylinders 60 disposed between the circuit boards 20 of the puzzle
building blocks capable of changing light-emitting areas. The
conductive cylinders 60, but not limited thereto, electrically
connect the circuit boards 20 of the puzzle building blocks to each
other. The circuit boards 20 of the puzzle building blocks capable
of changing light-emitting areas can also be electrically connected
with each other through an electric wire or connector.
[0051] In summary, the present invention changes the
light-and-darkness or the color of the light emitted from the
light-emitting element by building blocks such that the light
emitted from the light-emitting element can form letters or
patterns on one side of the puzzle building block.
[0052] Although the present invention has 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.
