Description

A building block and a building block kit Technical Field

[0001] The utility model relates to the technical field of building block toys, in particular to an interlocking building block and a building block kit. Background Art

[0002] Building blocks are a type of connecting toy formed by combining multiple units. Interlocking building blocks are a common type of building block, primarily connected together using male and female buckles. One unit has at least one raised male buckle, and the other connected unit has at least one recessed female buckle, which are used to interlock the blocks. This type of connecting building block is limited by the male and female buckle connection structure. When the building block is suspended in a horizontal direction, the amount of expansion is limited, and the connection itself is prone to loosening, limiting the number of possible shapes. Furthermore, the raised male buckle is typically cylindrical, which makes it prone to unintended rotation of the surrounding components connected by the male and female buckles. This results in limited stability, portability, and playability.

[0003] Based on the male and female buckle design, many different building blocks have been developed. For example, a six-sided expandable building block features trapezoidal (cross-sectional) slot buckles on four sides, a raised small cylindrical buckle on the fifth side, and a concave interface (female buckle) on the sixth side. These matching male and female buckles on the fifth and sixth sides allow for a variety of stable shapes. However, these building blocks also have their drawbacks. The trapezoidal slot buckle connection is laborious to assemble, making it difficult to insert and assemble, potentially injuring children and even adults. Disassembly is also difficult, reducing the enjoyment of repeated assembly and disassembly.

[0004] To facilitate assembly and disassembly, people invented magnetic building blocks. These blocks rely on the force of magnets to expand in multiple directions. However, these blocks also have certain drawbacks, primarily high manufacturing costs; limited magnetic force limits the amount of expansion a magnetic block can achieve when suspended in a horizontal direction, restricting the number of possible shapes; and the blocks' magnetic connection limits stability, making them difficult to transport and play with. Technical issues

[0005] In view of the above shortcomings, the purpose of the present invention is to provide a building block and a building block kit that can solve the problems of the existing building blocks such as difficulty in repeated disassembly and assembly, poor extensibility on all sides, and poor stability.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure. Example

[0071] As shown in FIG. 1 to FIG. 20 , a preferred embodiment of the present invention provides a building block, which mainly includes a building block unit 10 and a connecting rod 20 .

[0072] Continuing with Figures 1 to 7, there are at least two building block units 10. Of course, the number of building block units 10 is not limited and is primarily selected based on the specific finished product being assembled. It is understandable that for smaller, simpler building blocks, a relatively small number of building block units 10 are used, while for larger, more complex building blocks, a relatively large number of building block units 10 are used. The building block units 10 are cubic structures, with through holes 11 perpendicular to the sides of each corresponding pair of building block units 10. Thus, a cubic building block unit 10 has three through holes 11, which are perpendicular to the connected sides, and are perpendicular to each other and do not intersect. The cross-section of the through hole 11 is polygonal and equal in size, preferably a regular polygon, such as an equilateral triangle, a square, a regular hexagon or a regular octagon. In this exemplary embodiment, the cross-section of the through hole 11 is a square, and the left and right sides of the through hole 11 of the square cross-section are parallel to the left and right sides of the side surface through which it passes. The opening of the through hole 11 is located near the corner of each side surface. Assuming that the side surface through which the through hole 11 passes is divided into four equal parts according to the four quadrants, the opening of the through hole 11 is located in one of the equal parts. At the same time, the side distance between each through hole 11 and the side corner is consistent. In this exemplary embodiment, the side length of the building block unit 10 of the cubic structure is L, the side length of the square opening of the through hole 11 is 1 / 8L, and the side distance between the through hole 11 and the side corner is 1 / 8L.

[0073] Continuing with reference to Figures 2 to 7, the cross-section of the connecting rod 20 is consistent with the cross-section of the through-hole 11, so that when the connecting rod 20 is inserted into the through-holes 11 of two or more building block units 10, the two or more building block units 10 can be connected. The cross-section of the connecting rod 20 is a square with a side length of 1 / 8L. The length of the connecting rod 20 is not limited and can be selected according to specific needs. It is generally 1 / 2L, an integer multiple of L, or an integer multiple of L plus 1 / 2L. Of course, other sizes can also be selected according to specific needs. The number of connecting rods 20 also depends on the number of building block units 10 that need to be assembled. For forms that require the use of multiple connecting rods 20, the lengths of the multiple connecting rods 20 can be different.

[0074] In this preferred embodiment, the building block units 10 and the connecting rods 20 are cast and formed using materials such as plastic or metal. The manufacturing materials and manufacturing difficulty of the building blocks of the present invention are not significantly different from those of existing products, and are easy to obtain materials and produce.

[0075] During implementation, the desired building block shape is overlapped according to the needs of the splicing. For example, in a simple implementation method, a building block shape arranged side by side in the shape of a "one" is overlapped. At this time, the splicing connection of the multiple building block units 10 can be achieved by extending the multiple building block units 10 side by side along one side, and inserting at least one connecting rod 20 between the multiple building block units 10. For example, please refer to Figures 4 and 5. In a specific splicing building block, in the splicing of four building block units 10 extending side by side in one direction, the splicing connection can be achieved by using two 1.5L and one 1L connecting rods 20. The two 1.5L connecting rods 20 are located at both ends, and the 1L connecting rod 20 is located in the middle. At this time, each connecting rod 20 is inserted into the through-holes 11 of at least two building block units 10 to achieve the splicing of four building block units 10 extending side by side in one direction. Of course, other sizes of connecting rods 20 may also be used to achieve the connection, such as using a 1.5L connecting rod 20 and a 2.5L connecting rod 20, or other achievable methods, which will not be elaborated on in detail here. In another specific exemplary embodiment, please refer to Figures 6 and 7. The building block is in an inverted L shape as a whole. In the splicing of 6 building block units 10 extending side by side in two directions, 4 building block units 10 in a row can be connected to each other by using two 1.5L connecting rods 20 and one 1L connecting rod 20. The two 1.5L connecting rods 20 are located at both ends, and the 1L connecting rod 20 is located in the middle. At this time, each connecting rod 20 is at least inserted into the through holes 11 of two building block units 10 to achieve the splicing of 4 building block units 10 extending side by side in one direction. The building block units 10 in a row of 3 can be connected to each other by using two 1.5L connecting rods 20. Each connecting rod 20 is at least inserted into the through holes 11 of two building block units 10 to achieve the splicing of 3 building block units 10 extending side by side in one direction, thereby realizing the splicing of the building block in an inverted L shape. It is understandable that a plurality of building block units 10 that are extended and spliced ​​side by side in one direction can be spliced ​​through the same connecting rod 20 .

[0076] In the interlocking building blocks of the present invention, the interlocking of the building block units 10 is achieved through the connecting rod 20. Since the connecting rod 20 and the through-hole 11 into which it is inserted are polygonal in structure, the building block units 10 and the connecting rod 20 will not rotate relative to each other, i.e., no unintended rotation will occur. This ensures the stability of the building block work, ensuring its portability and playability. Disassembly of the building block units 10 and the connecting rod 20 is also simple. The connecting rod 20 can be pushed out of the through-hole 11 of the building block unit 10 using a push member, thus achieving simple assembly and disassembly, ensuring a high level of entertainment through repeated assembly and disassembly.

[0077] It is understood that, in this exemplary embodiment, two adjacent building block units 10 are closely attached to each other and their sides are aligned, while in other embodiments, it is not required that the two building block units 10 be closely attached to each other and / or their sides are aligned.

[0078] The interlocking building blocks of the present invention utilize multiple cubical building block units 10, two perpendicular, non-intersecting through-holes 11, and a removable connecting rod 20 to facilitate expansion of the cubic building block units 10 in six spatial (lateral) directions. The square through-holes 11, combined with the removable connecting rod 20 and a pushing tool, solve the problem of difficult assembly and disassembly of some existing interlocking building blocks. The connecting rod 20 allows for the creation of shapes with longer suspension distances than ordinary building blocks, providing more possibilities for the design of building block creations and solving the problems of limited spatial design and poor stability of existing interlocking building blocks. The combination of the connecting rod 20 and the through-hole 11 ensures the stability of the building block connection, solving the problem of poor stability of some existing interlocking building blocks. The interlocking building blocks of the present invention are easy to repeatedly disassemble and disassemble, have good directional expandability, and are stable, ensuring the entertainment value of repeated disassembly and assembly, and are highly portable and playable.

[0079] In a preferred embodiment, referring to Figures 9 to 14 , the building block further includes a base plate 30 . The base plate 30 is a flat plate-like structure. In this exemplary embodiment, the base plate 30 is 7L long, 6L wide, and 1.5L thick. A lower groove 33 is defined at the bottom of the base plate 30 . The lower groove 33 is a square groove, and the length, width, and depth of the lower groove 33 are all L. An upper through hole 34 is defined between the lower groove 33 and the top surface of the base plate 30 . The upper through hole 34 is a square hole, located directly in the center of the bottom of the lower groove 33 , and its vertical projection is directly in the center of the lower groove 33 . The cross-section of the upper through hole 34 is square, the side length of the square opening of the upper through hole 34 is 1 / 8L, and the depth of the upper through hole 34 is 0.5L.

[0080] The building block further includes a bottom block 32, the shape of which is consistent with the shape of the lower groove 33 so that the bottom block 32 can be placed in the lower groove 33. In this exemplary embodiment, the side length of the bottom block 32 is L.

[0081] A vertical rod 31 is fixed to the bottom block 32. When the bottom block 32 is placed in the lower groove 33, the vertical rod 31 can extend upward through the upper through hole 34. The length of the vertical rod 31 is not limited and can be selected according to actual needs. In this exemplary embodiment, the length of the vertical rod 31 is 2L. The cross-section of the vertical rod 31 is consistent with the cross-section of the through hole 11, so that the through hole 11 of the building block 10 can be inserted into the vertical rod 31 to enable the building block 10 to be assembled on the bottom plate 30.

[0082] During implementation, in a specific embodiment, the bottom block 32 is placed in the lower groove 33 of the base plate 30. At this time, the vertical rod 31 extends upward and passes through the upper through hole 34. At this time, the vertical rod 31 protruding from the top surface of the base plate 30 can be inserted into the building block unit 10. Specifically, the building block unit 10 is inserted into the vertical rod 31 through the through hole 11, and the building block unit 10 is now fixedly inserted on the base plate 30. The bottom block 32 and the vertical rod 31 thereon can be used to build a high column perpendicular to the horizontal plane. The base plate 30 can serve as a base to ensure stable support. The length of the vertical rod 31 can be selected according to actual conditions to achieve an integrated high column structure. Of course, it is understood that the building block units 10 can extend upward or sideways, so the vertical rod 31 does not need to be completely consistent with the height of the upwardly extending building block unit 10.

[0083] When the vertical rod 31 is not in use, such as when disassembling building blocks, the vertical rod 31 can be removed from the base 30 by removing the bottom block 32 from the base 30. The vertical rod 31 is located in the middle of the top of the base 30. This structural arrangement has the advantage that the force on the vertical rod 31 can be symmetrically distributed during unloading or installation, which can prevent the relatively slender vertical rod 31 from breaking or disconnecting during unloading or installation.

[0084] To facilitate removal of the bottom block 32 and its vertical rod 31, as shown in Figures 10 to 13 , the bottom of the base plate 30 is provided with a discharge slot 35. The discharge slot 35 communicates with the lower slot 33 at the sidewall, directly connecting the two slots. The discharge slot 35 has a length of L, a width of 0.7L, and a depth of 0.8L. A side hole 321 is provided on the side of the base block 32, directly opposite the point where the discharge slot 35 communicates with the lower slot 33. A discharge hook 40 is also included. The discharge hook 40 has a hook head 41 that can be inserted into the side hole 321, allowing the discharge hook 40 to be pulled to remove the base block 32 from the lower slot 33. In operation, the base block 32 can be removed from the lower slot 33 by inserting the hook head 41 of the discharge hook 40 into the side hole 321 and pulling the discharge hook 40. In a preferred embodiment, referring to Figure 14 , the unloading hook 40 is formed by bending a round rod into two sections. The diameter of the rod is 1 / 4L. The unloading hook 40 includes a central connecting portion 42, and a hook head 41 and a handle portion 43 located on either side. The side hole 321 of the bottom block 32 has a diameter of 1 / 4L and extends vertically through the two opposing side surfaces. The hook head 41 is L long, the connecting portion 42 is 3L long, and the handle portion 43 is approximately 9 cm long (based on the width of an adult's palm). During operation, the user grasps the handle portion 43 and places the hook head 41 into the unloading slot 35. The hook head 41 can then be inserted into the side hole 321 of the bottom block 32 through the unloading slot 35. The bottom block 32 can then be removed from the lower slot 33 by pulling the unloading hook 40.

[0085] There are multiple bottom blocks 32, so that the bottom plate 30 has multiple vertical rods 31. Correspondingly, the bottom plate 30 is provided with lower grooves 33 and unloading grooves 35, which are the same number as the bottom blocks 32. The multiple vertical rods 31 are arranged in a distributed manner, and when two building blocks 10 are respectively inserted into two adjacent vertical rods 31 in the same row, the distance between the two building blocks 10 is equal to an integer multiple of the side length of the building blocks 10. In this case, an integer multiple of the building blocks 10 can be placed between the two building blocks 10 to maintain a tight connection between the building blocks 10. In this case, please refer to Figure 13.

[0086] In a preferred embodiment, the building blocks further include a rotating shaft 50, which includes rotating shaft ends 51 located at both ends of the rotating shaft 50 and a rotating shaft portion 52 located between the two rotating shaft ends 51. The cross-section of the rotating shaft ends 51 is consistent with the cross-section of the through-hole 11 of the building block unit 10, so that the rotating shaft ends 51 can be matched and inserted into the building block unit 10. The size of the rotating shaft portion 52 is smaller than the through-hole 11 of the building block unit 10, so that when the building block 10 is mounted on the rotating shaft portion 52 of the rotating shaft 50 through the through-hole 11, it can rotate about the rotating shaft portion 52. In this preferred exemplary embodiment, the length of the rotating shaft end 51 is 1 / 2L, and the length of the rotating shaft portion 52 is 2L. The rotating shaft portion 5 is a round rod with an outer diameter equal to the side length of the rotating shaft end 51. Referring to Figures 15 and 16, the two building block units 10 located in the middle can rotate about the rotating shaft 50 through the through-hole 11. By providing the rotating shaft 50 to realize the rotating structure, rotatable components such as doors and windows can be obtained in the building blocks.

[0087] In a preferred embodiment, the building block further includes a facing piece 60. This facing piece 60 includes a facing portion 61 and a latch portion 62 disposed on the facing portion 61. The cross-section of the latch portion 62 matches the cross-section of the through-hole 11 of the building block 10, allowing the latch portion 62 to be inserted into the building block 10. The shape and size of the facing portion 61 can be selected according to specific needs. The cross-section of the latch portion 62 matches the cross-section of the through-hole 11 of the building block 10. In this preferred embodiment, the length of the latch portion 62 is 1 / 2L. The facing piece 60 can be used to create a variety of shapes, such as architectural doors and windows, human figures, trees, and spatial geometric surfaces, enriching the shape of the building block or serving as a decorative element, as shown in Figures 17 to 20. Of course, facing pieces 60 with more than two latch portions 62 can be positioned in the through-holes 11 of different building blocks 10, allowing different building blocks 10 to be connected and enhanced stability, as shown in Figure 20.
