Embodiments for Carrying Out the Invention

[0019] Hereinafter, the present invention will be described in detail with reference to specific examples. The following examples are helpful for those skilled in the art to further understand the present invention, but do not limit the present invention in any form. Those skilled in the art can make some modifications and improvements on the premise of not departing from the concept of the present invention. All of these belong to the protection scope of the present invention.

[0020] Figure 1 is a schematic structural view of a joint part in a building block system according to the present invention. As shown in Figure 1, the building block system is an arm part in a humanoid building block system, and the arm has a shoulder joint 801, an elbow joint 802, and a wrist joint 803. The humanoid building block system may also include joints such as thighs, knees, and ankles. By using the assembled and disassembled building block structure according to the present invention, these joints can be assembled or disassembled by hand without the user using tools. That is, the user can assemble or disassemble the male head part 100 of the male head building block 1 and the female head part 200 of the female head building block 2 that constitute the joint by hand. After the joint is assembled, the coaxially provided male head part 100 and female head part 200 can rotate relative to each other around the central axis, thereby realizing the rotational freedom of the joint. Further, after the assembly of the male head part 100 and the female head part 200 is completed, the fitting of the boss 101 of the male head part 100 and the second hole diameter part 202 that forms the annular groove 2020 of the female head part 200 can limit the relative displacement in the axial direction between the male head part 100 and the female head part 200, and the male head part 100 and the female head part 200 will not separate from each other due to the influence of gravity, thus solving the problem of preventing detachment.

[0021] Furthermore, joints are often used particularly in humanoid building block toys, and humanoid building blocks include realistic or scientific biological shape building blocks such as humans, animals, and monsters. For humanoid building block toys, the visual effect is very important, and the simulation objects include, for example, skeletons, muscles, skin, armor, weapons, etc. In addition to simulating the overall shape, it is necessary to simulate the visual effect that the surfaces of these objects are smooth, so it is necessary to minimize the occurrence of seams in the building blocks.

[0022] The present invention solves the problem of joints by an assembly and disassembly block structure. As shown in Figures 2, 3, and 4, the assembly and disassembly block structure according to the present invention includes a female head block 2 and a male head block 1, the male head block 1 and the female head block 2 being integrally injection molded using a mold, the male head block 1 including a male head portion 100, the male head portion 100 including a rod portion 102 and a boss 101 located on the side of the rod portion 102, the female head block 2 including a female head portion 200, the female head portion 200 having a first hole diameter portion 201 and a second hole diameter portion 202 provided coaxially along the direction from the hole opening 209 toward the inside of the hole, after the male head portion 100 and the female head portion 200 are assembled, the boss 101 is housed in the second hole diameter portion 202 and the male head portion 100 is assembled from the hole opening 209 to the female head portion 200. In a preferred example, the first bore diameter portion 201 and the second bore diameter portion 202 are provided adjacent to each other, and the bore walls of the first bore diameter portion 201 and the bore walls of the second bore diameter portion 202 are not smoothly connected. Because the maximum outer diameter of the boss 101 of the male head portion 100 is larger than the inner diameter of the first bore diameter portion 201, the first bore diameter portion 201 interferes with the boss 101 during the assembly process of both the male head portion 100 and the female head portion 200.

[0023] Furthermore, the female head portion 200 is integrally injection molded using a mold, and the value obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 of the female head portion 200 is 0.2 mm or less. Specifically, as shown in Figure 5, the integrally molded building block members are manufactured using a mold, and for building blocks having a recessed structure, such as building blocks having a female head portion 200, in the manufacturing process, in addition to the front and rear molds, slider pins are used to occupy the housing space within the recessed structure and mold the shape of the inside of the recessed structure. For example, the space occupied by the slider pins forms the opening of the female head portion 200, and the shape of the hole wall of the opening is formed by the shape of the side surface of the slider pins, thereby forming the hole wall of the first hole portion 201 and the hole wall of the second hole portion 202. During demolding, the front and rear molds are removed from the building block and the slider pins are removed from the building block according to the forced demolding process of the mold. When removing the slider pin, the slider pin is pulled out of the recessed structure of the building block. However, normally, the maximum inner diameter of the second hole diameter portion 202 is larger than the inner diameter of the first hole diameter portion 201. That is, the maximum outer diameter of the projection A of the second hole diameter portion 202 formed by the slider pin is larger than the outer diameter of the part B of the first hole diameter portion 201 formed by the slider pin. Furthermore, the rigidity of the metal mold for the slider pin is higher than that of the building block product (unlike the case where the male-head building block and the female-head building block are made of the same type of material with the same rigidity). Therefore, when removing the slider pin, the projection A and part B interfere with each other, making it impossible to remove and demold the slider pin, or forcibly removing it damages the building block product, causing the first hole diameter portion 201 to break and its inner diameter to enlarge. As shown in Figures 6 and 7, a comparison reveals that damage occurred in Figure 7, the first hole diameter portion 201 was undesirably enlarged, an annular groove was not formed in the second hole diameter portion 202, it could not engage with the projection of the male head building block, and therefore a clicking sound and click sensation could not be produced.

[0024] In contrast, in the present invention, the value obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 of the female head portion 200 is 0.2 mm or less. When this value is 0.2 mm or less, the rigid slider pin is removed and demolded without damaging the building block product, and the integrally formed female head portion 200 is obtained by demolding. In a preferred example, the value obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 of the female head portion 200 is 0.19 mm, 0.18 mm, 0.17 mm, 0.16 mm, 0.15 mm, 0.14 mm, 0.13 mm, 0.12 mm, or 0.11 mm or less.

[0025] Furthermore, the value obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 is 0.1 mm or more. In a preferred example, the value obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 is 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, or 0.19 mm or more. In this way, the user is given feedback accompanied by a click sound and a click sensation. As long as the upper and lower limits of the difference obtained by subtracting the inner diameter of the first hole portion 201 from the maximum inner diameter of the second hole portion 202 of the female head portion 200 are not contradictory, a person skilled in the art can obtain embodiments corresponding to various different combinations of upper and lower limits based on combinations of the above preferred examples, and such explanations are omitted here.

[0026] The present invention will be described in more detail below with reference to more preferred examples.

[0027] The second bore diameter portion 202 is an annular groove 2020, and the maximum outer diameter of the boss 101 is less than or equal to the maximum inner diameter of the second bore diameter portion 202. In this way, rotation of the male head portion 100 and the female head portion 200 around the central axis is enabled, and rotation of the humanoid building block joint is realized with one degree of freedom. More preferably, the boss 101 includes a first projection 1011 and a second projection 1012 located at both ends in the radial direction. The first projection 1011 and the second projection 1012 are provided facing away from each other in the radial direction of the male head portion 100 and are uniformly distributed in the circumferential direction, so that the rotation of the humanoid building block joint becomes smoother. The maximum outer diameter of the boss 101 is the distance between the vertex of the first projection 1011 and the vertex of the second projection 1012, for example, size 1 shown in Figure 4. If the boss 101 includes four or more even-numbered projections, the distance between the vertices of each pair of projections arranged facing each other radially on the male head portion 100 is equal to the maximum outer diameter of the boss 101. In a modified example, the boss 101 extends continuously in the circumferential direction of the male head portion 100 and is annular, and accordingly, the annular groove 2020 of the female head portion 200 engages with the annular boss 101.

[0028] The female head portion 200 has a first hole diameter portion 201, a second hole diameter portion 202, and a third hole diameter portion 203 which are provided coaxially along the direction toward the inside of the hole from the hole opening 209. The inner diameter of the third bore portion 203 is greater than or equal to the outer diameter of the portion of the rod portion 102 located on the distal end side of the boss 101. After the male head portion 100 and the female head portion 200 are assembled, portion A of the rod portion 102 located on the distal end side of the boss 101 is housed in the third bore portion 203.

[0029] When the inner diameter of the third bore portion 203 is equal to the outer diameter of the portion of the rod portion 102 located on the distal end side of the boss 101, the third bore portion 203 forms a flat structure, and the bore wall of the third bore portion 203 contacts the portion of the rod portion 102 located on the distal end side of the boss 101, and then adheres tightly to that portion, providing damping force and helping to stabilize the user's assembly operation.

[0030] If the inner diameter of the third bore portion 203 is larger than the outer diameter of the portion of the rod portion 102 located on the distal end side of the boss 101, the third bore portion 203 will not form a flat structure, and the clicking sound will be louder.

[0031] In a modified example, the second bore diameter portion 202 includes a first groove and a second groove located at both radial ends, the first groove and the second groove engaging with the first projection 1011 and the second projection 1012, respectively, that is, the male head portion 100 and the female head portion 200 can be assembled at only two relative azimuth angles.

They do not indicate or suggest that the shown device or component has a specific direction, or that it must be composed of and operated in a specific direction, and therefore should not be understood as limiting this application.
