Definitions
- the invention relates to a dove-shaped building block, and more particularly to a building block that utilizes a dovetailed recess and a dovetailed projection to engage two block bodies of the building blocks.
- Building blocks are one of the toys that have the greatest number of types. They are often in the forms of blocks of different geometric shapes and allow for stacking in different directions. Projections and recesses are formed on/in these building blocks to allow them to joint to each other through mating between the projections and the recesses.
- LEGO® blocks of which the feature is that a single square area is taken as a basic unit based on which expansion is made to a cube or a rectangular parallelepiped having an enlarged surface area or size. Projections (as well as counterpart recesses) are formed on the cube or the rectangular parallelepiped for jointing the blocks in a given (longitudinal) direction.
- the LEGO® blocks need adjustment of directions for 90, 180, or 270 degrees to complete the assembly of a large-sized or curved structure.
- special accessories may be necessary for such an assembly.
- the LEGO® blocks are designed to achieve a mating engagement between two blocks that is generally over tight, often resulting in difficulty in disassembling the blocks and requiring a large force to achieve so. This may lead to damage to the blocks. It is also known that disassembling tools are available for such disassembling operations.
- EP 0783908 A1 disclosed a toy building block puzzle having multiple side surfaces each being formed with either a lug or a slot.
- these two dove-shaped building blocks can be fixedly engaged in a cross manner.
- the dove-shaped building block mainly includes a block body.
- the block body shaped as a polygon, has a plurality of side surfaces alternately arranged with a dovetailed recess and a dovetailed projection. Further, a top surface and a bottom surface of the block body include respectively a post and a cavity for pairing the post.
- the stacking of the building blocks in either the longitudinal direction or the transverse direction can present convenience and stability in both assembly and disassembly of the building blocks.
- the top surface of the block body has a post, while the bottom surface of the block body has a cavity corresponding to the post in areas.
- the block bodies While in connecting a plurality of block bodies longitudinally, the block bodies can be connected in the longitudinal direction through the engagement of the post of one block body and the cavity of another block body. Thereupon, the plurality of the block bodies can be firmly connected so as to form a desired three-dimensional configuration.
- a thickness of the dovetailed projection of the dove-shaped building block is largely equal to the inner space provided by the dovetailed recess, such that the two dove-shaped building blocks can be firmly connected in a cross manner and thereby versatile combinations of the dove-shaped building blocks can be achieved.
- FIGS. 9 - 12 are embodiments of the invention according to the main claim.
- Figures 6 - 8 show features and structures of specific embodiments according to the dependent claims 6 and 3.
- Figures 1 - 5 are useful for the understanding of the invention.
- FIG. 1 is a perspective view showing a dove-shaped building block which is helpful for understanding a basic structure of the building block
- FIG.2 is a perspective view showing a regular connection of the dove-shaped building blocks of FIG.1
- FIG.2A is a perspective view showing the dove-shaped building blocks of FIG.1 joined through the regulation connection

- FIG.4 is a perspective view showing a reversed connection of the dove-shaped building blocks of FIG.
- FIG.4A is a perspective view showing the dove-shaped building blocks of FIG. 1 joined through the reversed connection.
- the dove-shaped building block includes a block body 1 shaped like a regular polygon configuration having even-numbered sides, for example but not limited to: regular hexagonal configuration, regular octagonal configuration, or other regular polygon configuration having even-numbered sides more than six sides.
- the invention takes the regular hexagonal configuration as the best embodiment of the block body 1, because the hexagonal configuration is a typical shape for allowing connection of two block bodies without a gap in between.
- the dove-shaped building block of the invention includes a block body 1 that has a regular hexagonal configuration having a top surface, a bottom surface opposite to the top surface, and six side surfaces 13, in which dovetailed recesses 11 and dovetailed projections 12 are alternately formed so that the side surfaces 13 respectively exhibit projecting and recessing configurations.
- the alternate arrangement adopted here is to have the dovetailed recesses 11 and the dovetailed projections 12 on the side surfaces 13 equal in number to each other.
- the hexagonal configuration or shape provides each side surface with an adjustment angle A1 of 60 degrees (that is, when rotating the block body 1 about a central axial line vertically penetrating through the center of the block body 1, a side surface of the block body 1 will be rotated to another neighboring side surface per 60 degrees of rotation, and there will be 360 degrees in total to rotate that side surface six times to go back its original position) so that rotated connection can be achieved with such a block body 1 for joining with an assembled structure of block bodies of the present invention to provide a three-dimensional configuration having a desired curve B.
- the block body 1 has a top surface on which a post 14 is formed, and a bottom surface in which an open cavity 15 is formed to correspond in shape and position to the post 14.
- the post 14 of one block body 1 may be fit into and in retaining engagement with the cavity 15 of another block body 1 so that the block bodies 1 may be joined in a longitudinal direction, allowing multiple block bodies 1 to be connected together to provide a secured and stable three-dimensional configuration.
- FIGS.3 and 3A six block bodies 1 are connected in a stacked manner, so as to form a two-level three-dimensional configuration, in which the separate block body 1 that is shown in phantom lines can be connected to the assembled structure of the remaining block bodies through mating engagement between the post 14 and the cavity 15.
- angular adjustment can proceed with 60 degrees for each step.
- FIGS.4 and 4A six block bodies 1 are connected in a stacked manner, so as to form a two-level three-dimensional configuration. Due to the mutual retaining engagement achievable between the dovetailed recess 11 and the dovetailed projection 12, a phantom-line block body 1 is connectable to an assembled structure of block bodies 1 in a reversed manner.
- FIG.5 shows examples of the block body in the form of a regular hexagonal block, a regular octagonal block, a regular decagonal block, and a regular dodecagonal block, respectively, to each of which the process of joining and stacking described above is applicable.
- the height of the block body 1, the post 14 and the cavity 15, and a through bore 17 may be changed and increased/decreased as desired for practical needs, allowing for more diverse ways of assembling or joining.
- the present invention allows for normal transverse and longitudinal connection, rotated connection, and reversed connection, which can be alternately and/or additionally used for joining the building blocks so that versatile variability of the block body 1 according to the present invention may be achieved, and flexibility of assembling the block bodies 1 for building unique three-dimensional structures may also be provided.

Description
- The invention relates to a dove-shaped building block, and more particularly to a building block that utilizes a dovetailed recess and a dovetailed projection to engage two block bodies of the building blocks.
- Various toys are available in the market for users to practice and improve coordination between hands and eyes. All these toys have different ways of playing and may be combined through diverse ways, making them suitable for practicing and improving the development of creativity.
- Building blocks are one of the toys that have the greatest number of types. They are often in the forms of blocks of different geometric shapes and allow for stacking in different directions. Projections and recesses are formed on/in these building blocks to allow them to joint to each other through mating between the projections and the recesses. One of the most commonly known building blocks is LEGO® blocks, of which the feature is that a single square area is taken as a basic unit based on which expansion is made to a cube or a rectangular parallelepiped having an enlarged surface area or size. Projections (as well as counterpart recesses) are formed on the cube or the rectangular parallelepiped for jointing the blocks in a given (longitudinal) direction. However, structural strength obtained with jointing in a single direction may be poor and collapse or detachment may result. The difficult for assembling a large structure is quite apparent. And, as such, the LEGO® blocks need adjustment of directions for 90, 180, or 270 degrees to complete the assembly of a large-sized or curved structure. In addition, special accessories may be necessary for such an assembly. Further, the LEGO® blocks are designed to achieve a mating engagement between two blocks that is generally over tight, often resulting in difficulty in disassembling the blocks and requiring a large force to achieve so. This may lead to damage to the blocks. It is also known that disassembling tools are available for such disassembling operations.
- Further, the conventional building blocks need to be assembled or disassembled piece by piece. Such a process of assembling or disassembling is generally time and labor consuming. Thus, further improvements are necessary.

EP 0783908 A1 disclosed a toy building block puzzle having multiple side surfaces each being formed with either a lug or a slot. - Accordingly, it is the primary object of the present invention to provide a dove-shaped building block that introduces a dovetailed recess and a dovetailed projection to engage two block bodies so as to make the assembly of the dove-shaped building blocks to be more extendable.
- It is another object of the present invention to provide a dove-shaped building block that introduces a post located at a top surface of a block body and a cavity located at a bottom surface of another block body to form an engagement pair for making the dove-shaped building block extendable in a longitudinal direction.
- It is a further object of the present invention to provide a dove-shaped building block that has a dovetailed projection of a block body to fit a dovetailed recess of another block body, such that one of the block bodies can be turned in a 90-degree manner so as to have the dovetailed projection thereof to engage a corresponding dovetailed recess of another block body. Thereupon, these two dove-shaped building blocks can be fixedly engaged in a cross manner.
- In the present invention, the dove-shaped building block mainly includes a block body. The block body, shaped as a polygon, has a plurality of side surfaces alternately arranged with a dovetailed recess and a dovetailed projection. Further, a top surface and a bottom surface of the block body include respectively a post and a cavity for pairing the post.
- While in connecting a plurality of the block bodies, different adjustment angles upon the side surfaces can be applied to join the block bodies through the engagement of the dovetailed projection of one block body and the dovetailed recess of another block body. Thereupon, a specific curved three-dimensional configuration of the assembly of the building blocks can be achieved. Further, via the engagement of the post of one block body and the cavity of another block body, longitudinal and angular adjustments upon the assembly of the block bodies can be feasible. Accordingly, by manipulating the longitudinal connections, the transverse connections, the angular connections, the reverse connections and the cross connections upon the building blocks of the present invention, variety of three-dimensional configurations of the stacked dove-shaped building blocks can be firmly obtained. In addition, by introducing parallel inclination surfaces to the upper end and the lower ends of the dovetailed projection of the block body, and further by forming the positioning points with the upper inclination facet of the corresponding dovetailed recess, the stacking of the building blocks in either the longitudinal direction or the transverse direction can present convenience and stability in both assembly and disassembly of the building blocks.
- In one embodiment of the present invention, the top surface of the block body has a post, while the bottom surface of the block body has a cavity corresponding to the post in areas. While in connecting a plurality of block bodies longitudinally, the block bodies can be connected in the longitudinal direction through the engagement of the post of one block body and the cavity of another block body. Thereupon, the plurality of the block bodies can be firmly connected so as to form a desired three-dimensional configuration.
- In one embodiment of the present invention, a thickness of the dovetailed projection of the dove-shaped building block is largely equal to the inner space provided by the dovetailed recess, such that the two dove-shaped building blocks can be firmly connected in a cross manner and thereby versatile combinations of the dove-shaped building blocks can be achieved.

FIG. 1 to FIG.4A ; whereFIG. 1 is a perspective view showing a dove-shaped building block which is helpful for understanding a basic structure of the building block,FIG.2 is a perspective view showing a regular connection of the dove-shaped building blocks ofFIG.1 ,FIG.2A is a perspective view showing the dove-shaped building blocks ofFIG.1 joined through the regulation connection,FIG.3 is a perspective view showing a rotated connection of the dove-shaped building blocks ofFIG.1 ,FIG.3A is a perspective view showing the dove-shaped building blocks ofFIG.1 joined through the rotated connection,FIG.4 is a perspective view showing a reversed connection of the dove-shaped building blocks ofFIG. 1 , andFIG.4A is a perspective view showing the dove-shaped building blocks ofFIG. 1 joined through the reversed connection. As shown, the dove-shaped building block includes ablock body 1 shaped like a regular polygon configuration having even-numbered sides, for example but not limited to: regular hexagonal configuration, regular octagonal configuration, or other regular polygon configuration having even-numbered sides more than six sides. The invention takes the regular hexagonal configuration as the best embodiment of theblock body 1, because the hexagonal configuration is a typical shape for allowing connection of two block bodies without a gap in between. The dove-shaped building block of the invention includes ablock body 1 that has a regular hexagonal configuration having a top surface, a bottom surface opposite to the top surface, and sixside surfaces 13, in which dovetailed recesses 11 and dovetailedprojections 12 are alternately formed so that the side surfaces 13 respectively exhibit projecting and recessing configurations. The alternate arrangement adopted here is to have the dovetailed recesses 11 and thedovetailed projections 12 on the side surfaces 13 equal in number to each other. When a number of such building blocks are joined, one of thedovetailed projections 12 of oneblock body 1 is set in mating engagement with one of the dovetailed recesses 11 of anotherblock body 1 to achieve connection of theblock bodies 1 in a transverse direction. The hexagonal configuration or shape provides each side surface with an adjustment angle A1 of 60 degrees (that is, when rotating theblock body 1 about a central axial line vertically penetrating through the center of theblock body 1, a side surface of theblock body 1 will be rotated to another neighboring side surface per 60 degrees of rotation, and there will be 360 degrees in total to rotate that side surface six times to go back its original position) so that rotated connection can be achieved with such ablock body 1 for joining with an assembled structure of block bodies of the present invention to provide a three-dimensional configuration having a desired curve B. Theblock body 1 has a top surface on which apost 14 is formed, and a bottom surface in which anopen cavity 15 is formed to correspond in shape and position to thepost 14. To join a number ofsuch block bodies 1, thepost 14 of oneblock body 1 may be fit into and in retaining engagement with thecavity 15 of anotherblock body 1 so that theblock bodies 1 may be joined in a longitudinal direction, allowingmultiple block bodies 1 to be connected together to provide a secured and stable three-dimensional configuration. - Referring now to
FIGS.3 and 3A , sixblock bodies 1 are connected in a stacked manner, so as to form a two-level three-dimensional configuration, in which theseparate block body 1 that is shown in phantom lines can be connected to the assembled structure of the remaining block bodies through mating engagement between thepost 14 and thecavity 15. In this example, theblock bodies 1 of the assembled structure and the phantom-line block 1 are both hexagonal so that the phantom-line block body 1 can be firstly rotated and then joined to the assembled structure so that the direction in whichadditional block bodies 1 joined thereto may be changed. Since the angle of a hexagon is (N-2)∗180 degrees = 720 degrees, each internal angle thereof is 120 degrees. Considering the sum of internal angles of a triangle, angular adjustment can proceed with 60 degrees for each step. The present invention is not limited to a hexagonal configuration and change to any regular polygon can be made as desired. Taking a regular octagon as an example, then (N-2) ∗ 180 degrees = 1080 degrees and each internal angle is 135 degrees. Considering the sum of internal angles of a triangle, angular adjustment can be conducted with 45 degrees for each step. Further taking a regular dodecagon as an example, then (N-2) ∗ 180 degrees = 1800 degrees and each internal angle is 150 degrees. Considering the sum of internal angles of a triangle, angular adjustment can be conducted with 30 degrees for each step. These examples are provided to illustrate that when theblock bodies 1 are joined or connected in a transverse direction for transverse connection, change of the angular positions thereof may be made through rotation so as to achieve versatile variability thereof. - Referring to
FIGS.4 and 4A , sixblock bodies 1 are connected in a stacked manner, so as to form a two-level three-dimensional configuration. Due to the mutual retaining engagement achievable between thedovetailed recess 11 and thedovetailed projection 12, a phantom-line block body 1 is connectable to an assembled structure ofblock bodies 1 in a reversed manner.FIG.5 shows examples of the block body in the form of a regular hexagonal block, a regular octagonal block, a regular decagonal block, and a regular dodecagonal block, respectively, to each of which the process of joining and stacking described above is applicable. As shown inFIG.6 , various modifications may be taken, wherein for example, the height of theblock body 1, thepost 14 and thecavity 15, and a throughbore 17 may be changed and increased/decreased as desired for practical needs, allowing for more diverse ways of assembling or joining. It can be understood from the above description that the present invention allows for normal transverse and longitudinal connection, rotated connection, and reversed connection, which can be alternately and/or additionally used for joining the building blocks so that versatile variability of theblock body 1 according to the present invention may be achieved, and flexibility of assembling theblock bodies 1 for building unique three-dimensional structures may also be provided. - In the first embodiment according to the present invention, as illustrated now in
FIGS.7-7D , wherein:FIG.7 is a perspective view showing a dove-shaped building block according to a first embodiment of the present invention;FIG.7A is a partial enlarged view showing the building block ofFIG.7 ;FIG.7B is a schematic enlarged view of a dashed circle ofFIG.7A , illustrating an inclination facet of the building block;FIG.7C is a schematic view illustrating joining connections of the building blocks ofFIG.7 ; andFIG.7D is a cross-sectional view ofFIG.7C along line A-A. Theblock body 1 is provided with a throughbore 17 formed in a center thereof and extending in an axial direction. The arrangement of thebore 17 allows for connection to be made to a shape-corresponding pillar-like or bar-like coupling section to achieve more diversified ways of connection or joining between theblock bodies 1. In addition, one or each of thedovetailed projections 12 of oneblock body 1 may be provided anupper inclination facet 121 and alower inclination facet 122 respectively on an upper end and a lower end thereof in the axial direction. The twoinclination facets block bodies 1 are stacked in a longitudinal direction, theupper inclination facet 121 of alower block body 1 is closely position-able against thelower inclination facet 122 of anupper block body 1 so that theblock bodies 1 exhibit a connected configuration. Namely, as theupper inclination facet 121 of theblock body 1 is posed at a 60-degree inclination, then thelower inclination facet 122 would be posed also at a 60-degree inclination, such that the parallel relationship can be maintained. Thereupon,additional block bodies 1 can be closely stacked to the existing assembly of theblock bodies 1, from either a lower position or an upper position, via the adherence of theupper inclination facet 121 and the correspondinglower inclination facet 122. - Refer now to
FIGS.8-8B ; whereFIG.8 is a schematic view illustrating joining connections of the building blocks according to a second embodiment of the present invention,FIG.8A is a cross-sectional view ofFIG.8 along line B-B, andFIG.8B is a schematic enlarged view of a dashed circle ofFIG.8A . As shown, while in stacking anadditional block body 1 to an existing assembly of theblock bodies 1 in a longitudinal direction, except for theinclination facets block bodies 1 already in the assembly have been closely positioned against each other, the lower end of thedovetailed recess 11 of theincoming block body 1 is to match the correspondingupper inclination facet 121 of theblock body 1 of the assembly so as to form apositioning point 16 for preventing theblock bodies 1 of the assembly from being separated due to forcing applied thereto in a transverse direction. With the positioning points 16 increase as the number of theblock bodies 1 in the assembly involved in the receiving of theincoming block body 1, finally all the upper andlower inclination facets block bodies 1, including theincoming block body 1, would come into engage so as to obtain a firm, stable and specific three-dimensional structure. - Refer now to
FIGS.9-9C ; whereFIG.9 is a perspective view showing a dove-shaped building block according to a third embodiment of the present invention,FIG.9A shows schematically a connection of two building blocks ofFIG.9 in a transverse direction,FIG.9B shows schematically a connection of two building blocks ofFIG.9 in a longitudinal direction, andFIG.9C shows schematically a connection of two building blocks ofFIG.9 in a cross manner. In this third embodiment, the dove-shaped building block 1a, as a block body shaped to have a regular hexagonal configuration, has atop surface 100, abottom surface 101 opposite and parallel to thetop surface 100, and sixside surfaces 13a connecting the top surface and the bottom surface. Preferably, each of the sixside surfaces 13a is substantially perpendicular to thetop surface 100 as well as thebottom surface 101. The block body 1a is defined with a predetermined height H1 (i.e. the distance measured from thetop surface 100 to the bottom surface 101). For a concise explanation, the sixside surfaces 13a are defined individually to be orderly a first side surface, a second side surface, a third side surface, a fourth side surface, a fifth side surface and a sixth side surface. Each of the first side surface, the third side surface and the fifth side surface is respectively provided with exactly one dovetailedrecess 11a located right in a middle portion thereof without anydovetailed projection 12a being provided thereon. On the other hand, each of the second side surface, the fourth side surface and the sixth side surface is respectively provided with exactly one saiddovetailed projection 12a located right in a middle portion thereof without any saiddovetailed recess 11a being provided thereon. Namely, thedovetailed recesses 11a and thedovetailed projections 12a are individually and orderly constructed to corresponding side surfaces 13a in an alternate manner. In another language, if oneside surface 13a has the dovetailedprojection 12a, then the neighboringside surface 13a (on either the right or the left hand side) would have the dovetailedrecess 11a. Equivalently, if oneside surface 13a has the dovetailedrecess 11a, then the neighboringside surface 13a (on either the right or the left hand side) would have the dovetailedprojection 12a. - In this third embodiment, when the two block bodies 1a, 1a' are connected in the transverse (i.e., horizontal) direction (as shown in
FIG.9A ), thedovetailed projection 12a of one of the block body 1a engages the corresponding dovetailedrecess 11a' of another block body 1a' in the transverse direction in such a manner that, the top surfaces of the block bodies 1a, 1a' of these two building blocks are lying on the same plane. Further, thetop surface 100 of the block body 1a has apost 14a located at a center thereof, while thebottom surface 101 of the same block body 1a has acavity 15a located at a center thereof with an area corresponding to the area of therespective post 14a. When a plurality of the block bodies 1a are connected in the longitudinal (i.e., vertical) direction (as shown inFIG.9B ), then thepost 14a of the lower block body 1a would engage thecavity 15a of the upper block body 1a, such that these two block bodies 1a can be stacked together in the longitudinal direction. - In addition, the maximum thickness d1 of the
dovetailed projection 12a on thecorresponding side surface 13a can be equal to the height H1 of the major portion of the block body 1a (i.e. d1=H1). Also, the profile of thedovetailed projection 12a is substantially fit to the inner space provided by thedovetailed recess 11a. Namely, the maximum thickness d1 of thedovetailed projection 12a is about equal to the maximum width w1 of thedovetailed projection 12a (that is, the outer end-surface of thedovetailed projection 12a is shaped like a square; d1=w1), and the d1 is also equal to the maximum width W1 of the inner space provided by thedovetailed recess 11a (i.e. d1=w1= W1). Thus, as shown inFIG.9C , the block body 1a can be turned in a 90-degree manner so as to have the dovetailedprojection 12a to engage the corresponding dovetailedrecess 11a of another said block body 1a' in a 90-degree cross manner (i.e. a 90-degree adjustment angle). Namely, the two top surfaces of these two block bodies 1a, 1a' would present a perpendicular plane pair (i.e. two planes in a 90-degree cross manner). Nevertheless, even under the engagement in a 90-degree cross manner, thedovetailed projection 12a of one block body 1a can still firmly engage thedovetailed recess 11a' of another block body 1a'. Namely, in this third embodiment, thedovetailed projection 12a protruding evenly in a gradually increasing manner from a generation rectangle on theside surface 13a of the block body 1a out to finally formed as a dovetail. Which means, the maximum width W1 of the inner space provided by thedovetailed recess 11a will be the width of theinner surface 110 of thedovetailed recess 11a; in addition, the maximum width w1 of thedovetailed projection 12a will be the width of the outer end-surface 120 of thedovetailed projection 12a; and moreover, the maximum thickness d1 of thedovetailed projection 12a will be the height of the outer end-surface 120 of thedovetailed projection 12a. Because the maximum width w1 is equal to the maximum thickness d1, therefore, it is clearly noted that, the shape of the outer end-surface 120 of thedovetailed projection 12a is definitely a square in this embodiment. Through the mating between thedovetailed projection 12a and the corresponding dovetailedrecess 11a, the extension of the assembly of the block bodies 1a, 1a' can be possible; particularly in a 90-degree cross manner. Thereupon, variety of the assembly of the building blocks can be true. - Refer now to
FIGS.10-10C ; whereFIG. 10 is a perspective view showing a dove-shaped building block according to a fourth embodiment of the present invention,FIG. 10A shows schematically a connection of two building blocks ofFIG. 10 in a transverse direction,FIG. 10B shows schematically a connection of two building blocks ofFIG. 10 in a longitudinal direction, andFIG.10C shows schematically a connection of two building blocks ofFIG. 10 in a cross manner. The fourth embodiment of the dove-shaped building block as shown inFIGS.10-10C is largely similar to the third embodiment thereof as shown inFIGS.9-9C , and thus details for the same elements or structures will be omitted herein. - In the present invention, the major difference between the fourth and the third embodiments of the dove-shaped building block is that the main portion of the block body of the fourth embodiment of the dove-shaped
building block 1b has a height H2 larger than the thickness d2 of thedovetailed projection 12b (i.e. H2 > d2). Also, thedovetailed projection 12b is approximately located in a middle portion or a center of thecorresponding side surface 13b in viewing the height and the width of theside surface 13b. Namely, the fourth embodiment of the dove-shapedbuilding block 1b has a height H2 larger than the height H1 of the third embodiment of the dove-shaped building block 1a (i.e. H2 > H1). In this embodiment, when two of theblock bodies FIG. 10A , thedovetailed projection 12b of oneblock body 1b is engaged into the corresponding dovetailedrecess 11b of anotherblock body 1b' in the transverse direction. Also, since the height H2 of theblock body 1b is larger than the thickness d2 of thedovetailed projection 12b (i.e. H2>d2), thus thedovetailed projection 12b would be fit completely into thedovetailed recess 11b and spaces would exist beyond the top surface and the bottom surface of thedovetailed projection 12b in thedovetailed recess 11b. - As a plurality of
block bodies 1b are connected in the longitudinal direction as shown inFIG. 10B , the post 14b of oneblock body 1b is engaged with the corresponding cavity 15b of the neighboringblock body 1b in the longitudinal direction, such that the plurality of theblock bodies 1b can be stacked in the longitudinal direction. In addition, as shown inFIG. 10C , oneblock body 1b can be turned by 90 degrees to have the dovetailedprojection 12b thereof to engage the corresponding dovetailedrecess 11b' of anotherblock body 1b' so as to pose these twoblock bodies block bodies - Refer now to
FIGS. 11-11C ; whereFIG. 11 is a perspective view showing a dove-shaped building block according to a fifth embodiment of the present invention,FIG.11A shows schematically a connection of two building blocks ofFIG. 11 in a transverse direction,FIG. 11B shows schematically a connection of two building blocks ofFIG. 11 in a longitudinal direction, andFIG. 11C shows schematically a connection of two building blocks ofFIG. 11 in a cross manner. - Since the fifth embodiment of the dove-shaped building block as shown in
FIGS. 11-11C is largely similar to the third embodiment thereof as shown inFIGS.9-9C , thus details for the same elements or structures will be omitted herein. In the present invention, the major difference between the fifth and the third embodiments of the dove-shaped building block is that the fifth embodiment of the dove-shaped building block has a block body 1c formed as a regular hexagonal configuration totally different to the aforesaid configurations. The block body 1c has a top surface, a bottom surface opposite to the top surface, and sixside surfaces 13c connecting and being parallel to the top surface and the bottom surface. Each of the sixside surfaces 13c is orderly to include an arc-like recess 11c or a ball-like button 12c. With the arc-like recess 11c and the ball-like button 12c individually set to the side surfaces 13c in an alternate manner, the side surfaces 13c of the building block is then formed to have a bumpy surface. In this embodiment, the volume of ball-like button 12c is just fit into the arc-like recess 11c. Namely, when oneside surface 13c includes one ball-like button 12c, then the neighboringside surface 13c (either right or left) would definitely include the arc-like recess 11c, and vice versa. - In addition, a ball-
like button 14c is constructed on the top surface of the block body 1c, while a corresponding arc-like recess 15c is constructed on the bottom surface of the block body 1c. When the two block bodies 1c, 1c' are connected transversely as shown inFIG. 11C , the ball-like button 12c of one block body 1c is fit into the corresponding arc-like recess 11c' of another block body 1c' in the transverse direction. On the other hand, as a plurality of block bodies 1c are connected in the longitudinal direction as shown inFIG. 11B , then the ball-like button 14c of the lower block body 1c would fit into the arc-like recess 15c of the upper block body 1c, such that these block bodies 1c can be stacked in the longitudinal direction. Similarly, as shown inFIG. 11C , the block body 1c can be turned by 90 degrees so as to have its ball-like button 12c to angularly engage the arc-like recess 11c' of another horizontal block body 1c'. Thus, these two block bodies 1c, 1c' can be fixedly connected in a 90-degree cross manner, and thereby variety in three-dimensional configuration for stacking the building blocks can be achieved. - Referring now to
FIG. 12 , a perspective view showing a dove-shaped building block according to a sixth embodiment of the present invention is shown. Since the sixth embodiment of the dove-shaped building block as shown inFIG. 12 is largely similar to the third embodiment thereof as shown inFIGS.9-9C , and thus details for the same elements or structures will be omitted herein. In the present invention, the major difference between the sixth and the third embodiments of the dove-shaped building block is that, in this sixth embodiment, the dove-shaped building block 1d further includes a throughbore 18d located at a center of the block body 1d and penetrating from the top surface to the bottom surface of the block body 1d. In the present invention, the cross section of the throughbore 18d can be shaped as one of a circle, a triangle, a quadrangle, a pentagon, a hexagon, or any polygon the like. In this sixth embodiment, the throughbore 18d of the block body 1d is preferably embodied as a regular hexagonal bore. With this regular hexagonal bore as the throughbore 18d, theposts 14a of two block bodies 1a ofFIG.9 can be fit into the throughbore 18d of the block body 1d from the top and the bottom ends of the block body 1d, so as to form a longitudinal combination of the block bodies. Namely, one block body 1d is sandwiched by two block bodies 1a. Further, strip-like or column-like polygonal connection members can be introduced to penetrate the connected throughbores 18d of the stacked block bodies 1d, so as to make the connection of the block bodies 1a, 1 d more versatile. - In summary, the dove-shaped building block in accordance with the present invention mainly includes the
block body 1 having a plurality of the side surfaces 13. Thedovetailed recess 11 and thedovetailed projection 12 are alternately and individually arranged to the side surfaces 13. While in connecting a plurality of theblock bodies 1, different adjustment angles upon the side surfaces 12 can be applied to join theblock bodies 1 through the engagement of onedovetailed projection 12 of oneblock body 1 and thedovetailed recess 11 of anotherblock body 1. Thereupon, a specific curved three-dimensional configuration of the assembly of the building blocks can be achieved by manipulating the longitudinal connections, the transverse connections, the angular connections, the reverse connections and the cross connections of the block bodies. Thus, variety of three-dimensional configurations of the stacked dove-shaped building blocks can be obtained. - While the present invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the scope of the invention. The scope of the invention is defined by the appended claims.
