TECHNICAL FIELD

[0001] The present application relates to the technical field of toys, in particular to a jointed building block assembly and a toy. BACKGROUND

[0002] Building block toys are very popular among children and parents due to their interesting and intellectual nature.

[0060] The application will be described in detail below with specific examples. The following examples will help those skilled in the art to further understand the application, but do not limit the application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the application. These are within the scope of the present application.

[0061] Example 1:

[0062] The application provides a joint block assembly, as shown in Figure 1 、 Figure 2 、 Figure 3 The joint block assembly comprises a block body 1, an intermediate block 2 and a limb block 3. The block body 1 is provided with a first splicing structure 11 on each side. The intermediate block 2 is provided with a second splicing structure 21 which is matched with the first splicing structure 11. Therefore, the intermediate block 2 can be spliced on the first splicing structure 11 through the second splicing structure 21, so that the intermediate block 2 is spliced with the block body 1. The spliced intermediate block 2 can rotate relative to the block body 1. The first splicing structure 11 is preferably a support extending from each side of the bottom end of the block body 1. The support is provided with a first groove 111, a second groove 112 and a third groove 113 which are arranged at intervals from the end to the root. The second splicing structure 21 is preferably a splicing hole which is provided with a first boss 211 and a second boss 212 arranged at intervals on the inner wall. The first boss 211 is a ring boss or part of a ring boss. The second boss 212 is a ring boss or part of a ring boss.

[0063] It should be noted that the second splicing structure 21 spliced on the first splicing structure 11 can slide in the axial direction of the first splicing structure 11 under the driving of an external force, so that the second splicing structure 21 can slide between a first position and a second position. When the second splicing structure 21 is in the first position, the first boss 211 is located inside the first groove 111. When the second splicing structure 21 is in the second position, the second boss 212 is located inside the second groove 112.

[0064] Further, the limb block 3 is spliced outside the intermediate block 2 through a third splicing structure 31. During the process of switching between the upright state and the split state of the limb block 3 relative to the block body 1, the intermediate block 2 can move between the first position and the second position relative to the first splicing structure 11 under the extrusion force of the limb block 3. During the process of switching between the upright state and the leg lifting state of the limb block 3 relative to the block body 1, the limb block 3 rotates relative to the intermediate block 2 and / or the intermediate block 2 rotates relative to the block body 1. Therefore, the application can realize the action of large-angle leg swinging forward and backward, such as the action of leg swinging to 90°, as shown inFigure 11 As shown; it can also perform left and right splits, such as Figure 7 As shown.

[0065] Specifically, the external shape of the middle block 2 is preferably a second ball-head structure, and the third splicing structure 31 is a second ball-and-socket structure that matches the second ball-head structure. One side of the second ball-and-socket structure has an arc-shaped concave edge 311. When the middle block 2 is in the first position, such as Figure 4 As shown, the first boss 211 is located inside the first groove 111, and in its natural state, the first groove 111 limits the axial movement of the first boss 211; when the middle block 2 is in the second position, as... Figure 7 As shown, the second boss 212 is located inside the second groove 112, and the arc-shaped concave edge 311 contacts and abuts against the bottom of the third groove 113. When the arc-shaped concave edge 311 enters the third groove 113, the surface of the arc-shaped concave edge 311 extends to the outside of both sides of the bottom of the third groove 113. At this time, the limb block 3 is in a split state.

[0066] like Figure 2 As shown, the second groove 112 connects to the third groove 113, and the depth of the third groove 113 is greater than that of the second groove 112. During the movement of the limb block 3 from the upright state to the split state, the arc-shaped concave edge 311 gradually enters the third groove 113 until it contacts and abuts against the bottom of the third groove 113. At this time, the shape of the arc-shaped concave edge 311 can match and engage with the shape of the third groove 113. At the same time, the inner wall of the second ball socket structure squeezes the outer wall of the middle block 2, causing the middle block 2 to move from the first position to the second position. During this process, under the squeezing and pushing force of the limb block 3, the first boss 211 located in the first groove 111 is separated from the first groove 111 and moves away from the support until the arc-shaped concave edge 311 contacts and abuts against the bottom of the third groove 113. The second boss 212 slides into the second groove 112.

[0067] It should be noted that the inner diameter of the opening of the second ball socket structure is smaller than the outer diameter of the second ball head structure, and the second ball head structure can pass through the opening under the force of hand. The insertion and extraction force of the second ball head structure into or out of the second ball socket structure is required by manual splicing. Therefore, the middle block 2 and the leg block 3 can be stably kept together in a natural state, which increases the stability of the building block toy.

[0068] The maximum outer diameter of the support is greater than the minimum inner diameter of the splicing hole, and the splicing hole becomes more elastic under the force of hand, thus allowing the support to pass through. This means that the support needs to be manually inserted or removed from the splicing hole. Therefore, the middle block 2 and the block body 1 can be stably kept together in their natural state, increasing the stability of the building block toy.

[0069] The limb block 3 has sliding damping in the process of switching between the upright state and the split state, the sliding damping is from between the limb block 3 and the middle block 2 and / or from between the limb block 3 and the block body 1, and the blocks are spliced or deformed with damping feeling, the hand feeling of children when playing is improved, and the seniority of the toy is enhanced.

[0070] As shown in Figure 1 When viewed from the outside of the limb block 3, the limb block 3 can shield the middle block 2, so that the middle block 2 is hidden, and the outer surface of the end of the limb block 3 close to the middle block 2 is a smooth transition convex surface, so that only the smooth transition outer surface can be seen when the toy is viewed from the outside, and the aesthetic degree of the toy is increased.

[0071] The block body 1 is further provided with at least one fourth splicing structure 12, and the limb block 3 is further provided with at least one fifth splicing structure 32, the fourth splicing structure 12 and the fifth splicing structure 32 are used for splicing other blocks, for example, the fourth splicing structure 12 is used for splicing a torso of a toy person, and the fifth splicing structure 32 is used for splicing a lower leg or a foot of a toy person; the fourth splicing structure 12 can be a male head or a female head, and the fifth splicing structure 32 can be a male head or a female head.

[0072] The application further provides a toy comprising the joint block assembly, for example, the toy is a block person toy, and the joint block assembly is used for splicing a hip joint part of the block person.

[0073] Embodiment 2:

[0074] This embodiment is a variation of embodiment 1.

[0075] The embodiment provides a joint block assembly comprising a block body 1, a middle block 2 and a limb block 3, wherein the limb block 3 is designed as an upper limb shape of a toy person, the block body 1 is designed as a neck of a human body, the fourth splicing structure 12 can be used for splicing a head of the toy person, and the fifth splicing structure 32 is used for splicing an arm of the toy person; when the limb block 3 moves left or right relative to the block body 1, the limb block 3 can switch between an upright state and an arm stretching state, and in the process of switching from the upright state to the arm stretching state, the middle block 2 moves from a first position to a second position relative to the first splicing structure 11 under the extrusion of the limb block 3; when the limb block 3 moves forward or backward relative to the block body 1, the limb block 3 can switch between the upright state and an arm lifting state, and in the process of switching between the upright state and the arm lifting state, the limb block 3 rotates relative to the middle block 2 and / or the middle block 2 rotates relative to the block body 1.

[0076] In this embodiment, the first splicing structure 11 is a first ball head structure extending from the bottom end of the building block body 1, and the first ball head structure is sequentially and spacedly provided with a second groove 112 and a third groove 113 from the end to the root. Figure 15 、 Figure 16 The second splicing structure 21 is a first ball socket structure, and the inner wall of the first ball socket structure is spacedly provided with a first boss 211 and a second boss 212; when the intermediate building block 2 is located at the first position, the second boss 212 is located inside the second groove 112; when the intermediate building block 2 is located at the second position, the first boss 211 is located inside the second groove 112, and the first splicing structure 11 and the second splicing structure 21 can also achieve the effects in the application by adopting the matching ball head and ball socket structure.

[0077] Taking the embodiment 1 as an example, the action principle of the application is as follows:

[0078] When the intermediate building block 2 is located at the first position, as shown in Figure 4 , the first boss 211 is located inside the first groove 111 and is limited in the axial direction of the first boss 211 in the natural state, and the limb building block 3 is in the upright state; when the left limb building block 3 gradually splits legs to the left from the upright state and the right limb building block 3 gradually splits legs to the right from the upright state, the inner surface of the second ball socket structure slides relative to the outer surface of the second ball head structure; when the end of the second ball socket structure abuts against the outer surface of the building block body 1, as shown in Figure 5 、 Figure 12 , the inner surface of the second ball socket structure continues to slide relative to the outer surface of the second ball head structure; at this time, the inner surface of the second ball socket structure extrudes the outer surface of the second ball head structure to drive the intermediate building block 2 to slide towards one side of the outer end surface of the pillar, and the first boss 211 is separated from the first groove 111, as shown in Figure 6 、 Figure 13 , the intermediate building block 2 slides towards one side of the outer end surface of the pillar until the arc-shaped concave edge 311 contacts and abuts against the groove bottom of the third groove 113, as shown in Figure 7 、 Figure 14 , at this time, the second boss 212 is located inside the second groove 112, and the limb building block 3 is in the split state.

[0079] When the limb building block 3 in the upright state makes a leg lifting action forward relative to the building block body 1, as shown in Figure 8 、 Figure 9 , the limb building block 3 rotates relative to the intermediate building block 2 and / or the intermediate building block 2 rotates relative to the building block body 1 until the leg swinging action reaches 90°, as shown in Figure 10 、 Figure 11 , the side surface of the limb building block 3 is limited by the middle section 13 of the building block body 1.
