Description

Action Figures Technical Field

[0001] The present invention belongs to the field of toys, and in particular, relates to a humanoid doll. Background Art

[0002] The human-shaped doll is composed of a head, a torso, and limbs. The limbs include arms, hands, legs, and feet. These parts are connected by joints, and some joints use a ball head and socket structure.

[0003] Depending on the height of the human-shaped dolls, the ball heads of the joints of taller human-shaped dolls have larger diameters, while the ball heads of the joints of shorter human-shaped dolls have smaller diameters. The ball head diameters of human-shaped dolls of different heights are not standardized, which makes it impossible for users to assemble parts of human-shaped dolls of different heights using the standardized ball heads.

[0004] However, the standardization of the ball head diameter used to form the joint is not arbitrary. Inappropriate standardization of the ball head diameter will lead to a reduction in the degree of realism of the human-shaped doll. For example, a ball head with an overly large diameter is not suitable for a human-shaped doll with a shorter height. Summary of the Invention

[0054] The figure shows: DETAILED DESCRIPTION

[0055] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0056] The present invention provides a humanoid doll, wherein the shoulder joint and the hip joint of the humanoid doll both adopt a ball head and ball socket structure; the ball head is a universal ball head and adopts the same diameter.

[0057] The diameter x of the ball head is less than or equal to (0.618h-4) / 4.8 mm, where h represents the height of the humanoid doll. The ball head of the humanoid doll of a first height is adapted to fit into a joint socket at the same joint and / or at a different joint of a humanoid doll of a second height that is different from the first height. The insertion and removal force of the joints of the arm limb decreases from the shoulder joint along the direction extending from the arm limb to the palm; the insertion and removal force of the joints of the leg limb decreases from the hip joint along the direction extending from the leg limb to the sole of the foot.

[0058] For a human-shaped doll with a height of h mm, according to the ratio of the golden rectangle of 0.618, that is, width / length = 1 / 1.618, which is approximately equal to 0.618, the width of the human-shaped doll should be less than or equal to the product of h mm multiplied by 0.618, 0.618h mm. Otherwise, the proportions of the human-shaped doll will be seriously unbalanced, resulting in a reduction in the degree of simulation.

[0059] Let x be the diameter of the ball head and y be the wall thickness of the socket. In the structure of the human-shaped doll, the shoulder joint of the human-shaped doll adopts a ball head and socket structure, and the hip joint of the human-shaped doll adopts a ball head and socket structure. The diameter of the shoulder joint ball head is equal to the diameter of the hip joint ball head. Between the shoulder joint and hip joint located on the left or right side, the shoulder joint ball head is located on the outside of the hip joint ball head, and the center of the shoulder joint ball head is located at least x outside the center of the hip joint ball head, that is, one ball head diameter x; the gap width between the left and right hip joint ball heads is at least 1.8x, that is, 1.8 ball head diameters 1.8x. Among them, the gap width between the left and right hip joint ball heads must take into account the width occupied by the ball head itself and the crotch. The crotch is located between the root of the left leg and the root of the right leg of the human-shaped doll, separating the root of the left leg and the root of the right leg of the human-shaped doll.

[0060] As shown in Figure 1, the components on the left side of the humanoid doll are shown, including the left shoulder joint ball head 201, the left shoulder joint ball socket 301, the left hip joint ball head 203, and the left hip joint ball socket 303. Also shown are the components on the right side of the humanoid doll, including the right shoulder joint ball head 202, the right shoulder joint ball socket 302, the right hip joint ball head 204, and the right hip joint ball socket 304. The left shoulder joint ball head 201 is located outside the left hip joint ball head 203, with the center of the left shoulder joint ball head 201 located at a point x to the left and outward of the center of the left hip joint ball head 203. The right shoulder joint ball head 202 is located outside the right hip joint ball head 204, with the center of the right shoulder joint ball head 202 located at a point x to the right and outward of the center of the right hip joint ball head 204. The gap width between the left hip joint ball head 203 and the right hip joint ball head 204 is 1.8x.

[0061] The width gap between the left and right hip joints is 1.8x. The width gap between the left shoulder and hip joints is x. The width gap between the right shoulder and hip joints is x. The left shoulder socket and its wall thickness, outward from the left shoulder ball center, is 0.5x+y. The right shoulder socket and its wall thickness, outward from the right shoulder ball center, is 0.5x+y.

[0062] Therefore, in the present invention, for the human-shaped doll structure, the width of the human-shaped doll will occupy at least a width of 4.8x+2y, that is, 1.8x+x+x+0.5x+y+0.5x+y.

[0063] In the human-shaped doll structure, considering the stability of the ball socket, the ball socket wall thickness y is at least 2 mm, that is, 2y occupies at least 4 mm of width. Therefore, the width of the human-shaped doll will occupy at least 4.8x+4 mm.

[0064] In order to make 4.8x+4 mm smaller than or equal to the 0.618h mm, the joint ball head diameter x must be smaller than or equal to (0.618h-4) / 4.8 mm.

[0065] Next, the present invention will be described.

[0066] There is not necessarily any overlap between the diameter ranges of the joint ball heads suitable for humanoid dolls of different heights.

[0067] On the one hand, the joint ball head surface matches the inner wall of the socket. During injection molding, no injection port is provided at the ball head position, ensuring a smooth and uniform surface color. When the ball head diameter is greater than 18.6 mm, flow marks will form on the ball head surface. To ensure the quality of the ball head, the joint ball head diameter must be less than or equal to 18.6 mm. When the height h of the humanoid doll is 150.9 mm, the joint ball head diameter x must be less than or equal to (0.618h-4) / 4.8 mm, so the ball head diameter x must be less than or equal to 18.6 mm. When the height h of the human-shaped doll exceeds 150.9 mm, for example, when h is 200 mm, the diameter x of the joint ball head must be less than or equal to (0.618h-4) / 4.8 mm, and the diameter x of the ball head must be less than or equal to 24.9 mm. Furthermore, for a ball head with a diameter greater than 18.6 mm and less than or equal to 24.9 mm, although its size meets the width requirement of a human-shaped doll with a height h of 200 mm, the joint ball head cannot meet the requirement of no flow marks in terms of process. As a result, due to factors such as shape and proportion coordination, human-shaped doll products with a height h of 200 mm either use a joint ball head with a diameter greater than 18.6 mm, which is coordinated but has flow marks, or a joint ball head with a diameter less than or equal to 18.6 mm, but has some uncoordinated shape and proportions, which is not conducive to universalization. Therefore, the height h of the humanoid doll is limited to less than or equal to 150.9 mm, so that the proportion-coordinated joint ball head at a height of 150.9 mm meets the process requirement of no flow marks, avoiding the problem of not being able to take into account the process flow marks and the proportion coordination of the ball head joint.

[0068] On the other hand, the human-shaped doll is made of plastic, such as ABS plastic. The diameter of the ball head limits the diameter of the shaft, which is smaller than the diameter of the ball head. If the ball head diameter is too small, the shaft diameter will also be too small, resulting in the plastic shaft being easily broken when the taller human-shaped doll is assembled and disassembled. For a human-shaped doll with a height h of 150.9 mm, the joint ball head diameter x is greater than or equal to 3.4 mm, and the shaft diameter is greater than or equal to 2.5 mm. This ensures that the shaft is not easily broken when the user assembles the 150.9 mm tall human-shaped doll. At the same time, the damping force of the ball head and the ball socket can maintain the joint of the 150.9 mm tall human-shaped doll at a fixed rotation angle. Furthermore, the shaft diameter limits the range of motion of the joint. The larger the shaft diameter, the smaller the joint range of motion. Therefore, the upper limit of the shaft diameter is determined based on the ball head diameter and the required range of motion of the joint.

[0069] Considering further that the way to play with a human-shaped doll is to assemble and disassemble it, if the height h of the human-shaped doll is less than 50 mm, the parts are too small, making it difficult to hold with bare hands. When the height h of the human-shaped doll is 50 mm, according to the diameter x of the joint ball head, which must be less than or equal to (0.618h-4) / 4.8 mm, x must be less than or equal to 5.6 mm. Accordingly, in order to quantify the height of the human-shaped doll and the universality of the joint ball head, the diameter x of the joint ball head of the human-shaped doll is greater than or equal to 3.4 mm and less than or equal to 5.6 mm, so as to be suitable for human-shaped dolls with a height h greater than or equal to 50 mm and less than or equal to 150.9 mm. In other words, the diameter x of the ball head is made greater than or equal to 3.4 mm and less than or equal to 5.6 mm, so as to be universally applicable to two or more human-shaped dolls of different heights with a height h greater than or equal to 50 mm and less than or equal to 150.9 mm. For example, a standardized universal joint ball head diameter x is 4.9 mm. This 4.9 mm diameter joint ball head is suitable for human-shaped dolls with a height h greater than or equal to 50 mm and less than or equal to 150.9 mm. For example, the diameter x of the joint ball heads used in human-shaped dolls with heights of 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, and 150 mm are all the same, 4.9 mm, thereby enabling universal assembly of human-shaped dolls of different heights. The wall thickness of the joint ball socket that matches the joint ball head is the same within a human-shaped doll and between human-shaped dolls of different heights.

[0070] The interference between the ball head and the socket is 0.02-0.05 mm to provide appropriate rotation damping. The undercut between the ball head and the socket is 0.02-0.12 mm to provide appropriate insertion and extraction force.

[0071] The present invention is further described below.

[0072] As shown in Figure 5 , some joints of the humanoid doll utilize a hole-and-hole-column structure. A first column 502 is coaxially disposed within the hole, and a clearance hole 602 is defined within the hole column 601. When the hole column 601 is inserted into the hole, the first column 502 is positioned within the clearance hole 602. In the axial direction, the distance between the first column 502 and the hole opening is less than or equal to the radius of the ball head. This allows the user to easily remove the ball head if it is mistakenly inserted into the hole, without the ball head being deeply embedded in the hole, making it difficult to remove.

[0073] The joints with hole and hole-column structures are, for example, axial joints, i.e., the upper arm 500 of the humanoid doll has a hole structure, and the lower arm 600 has a hole-column structure. The diameters of the holes and columns are the same, 3.3-3.5 mm, to provide suitable structural strength.

[0074] The interference between the hole column and the hole is 0.04-0.12 mm to provide appropriate damping. The undercut between the hole column and the hole is 0.02-0.12 mm to provide appropriate insertion and extraction force.

[0075] The diameter of the ball head is equal to the diameter of the hole column, for example, both are 3.4 mm.

[0076] More preferred examples of the present invention are described below.

[0077] The diameter of the ball head is 3.4-5.6 mm, suitable for human-shaped dolls of various heights ranging from 50-150.9 mm. The diameter of the ball head is, for example, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, or 5.6 mm. The height from the soles of the feet to the top of the head of the human-shaped doll is the height of a human-shaped doll. The human-shaped doll has a human-like appearance, a human-like standing animal appearance, or a human-like standing monster appearance, and has a head, a torso, arms, palms, legs, and soles of the feet. These components are connected by joints, some of which use a ball-head and ball-socket structure. The hip portion of the torso has a crotch portion. Joints such as the neck, wrist, waist, knee, and ankle can use a ball-and-socket configuration or a hole-and-hole-post configuration. For the shoulder joint, the ball is located in the torso and the socket in the arm. For the hip joint, the ball is located in the hip and the socket in the leg.

[0078] The present invention will be described in more detail below with reference to more preferred examples.

[0079] The shoulder and hip joints of the second-height humanoid doll both utilize a ball head and socket structure; the ball head of the first-height humanoid doll is adapted to the joint socket and / or hole of the second-height humanoid doll, which is different from the first-height humanoid doll; the end of the part of the second-height humanoid doll with the hole, away from the hole, has a ball head with a diameter different from the diameter of the universal ball head, or has a socket that does not match the universal ball head. Taking Figure 3 as an example, the upper arm component of the humanoid doll shown in Figure 3 is the component with the hole, that is, the lower end of the upper arm component has a blind hole, and the upper end of the upper arm component has a socket. In one variation, the socket at this location of the second-height humanoid doll can be made into a socket that does not match the size of the universal ball head, thereby achieving the transition from ball heads of different sizes to the socket through the upper arm component of the second-height humanoid doll. In another variation, the ball socket of the second height humanoid doll can be replaced with a ball head with a diameter different from the universal ball head, so that the ball heads of different suitable sizes can be transferred to each other through the upper arm component of the second height humanoid doll.

[0080] In a preferred embodiment, the height of the human-shaped doll A is 50 mm, and the height of the human-shaped doll B is 100 or 150 mm.

[0081] The ball joints of Figure A's shoulders, hips, and waist all have a uniform diameter of 4.9mm, while the wrist, ankle, and neck joints all have a uniform diameter of 3.4mm, which differs from the diameters of the shoulder, hip, and waist joints. The elbow and knee joints utilize a hole-and-hole-column structure, with the inner diameter of the hole being 3.4mm, the same as the wrist, ankle, and neck joints. The upper portion of the upper arm features a socket that mates with the 4.9mm diameter ball, while the lower portion of the upper arm features a hole with an inner diameter of 3.4mm. The upper portion of the lower arm features a hole-and-column that inserts into the 3.4mm inner diameter hole of the upper arm, while the lower portion of the lower arm features a 3.4mm diameter wrist ball.

[0082] The diameter of the ball joints for Figure B's shoulders, hips, waist, wrists, ankles, and neck joints is consistent at 4.9mm, the same as the diameters of Figure A's shoulders, hips, and waist joints. The elbow and knee joints use a hole-and-hole-column structure, with a consistent inner diameter of 3.4mm. This differs from the 4.9mm diameter of the ball joints for the shoulders, hips, waist, wrists, ankles, and neck joints, but the inner diameter of the holes for the elbows and knees is 3.4mm, the same as Figure A's. The upper part of the thigh component is a socket that fits the 4.9mm diameter ball, while the lower part of the thigh component has a hole with an inner diameter of 3.4mm, the same as Figure A's wrist, ankle, and neck joints.

[0083] In humanoid figure A, joint ball heads with the same diameter can be interchanged and spliced ​​together, for example, a thigh joint with a 4.9mm diameter ball head can be spliced ​​to the shoulder joint. Joint head balls and holes of the same size can also be spliced ​​together, for example, a 3.4mm diameter ankle joint ball head can be spliced ​​to a 3.4mm inner diameter hole in the upper arm. Furthermore, because the upper part of the upper arm is a ball socket that matches the 4.9mm ball head, conversion between 3.4mm and 4.9mm diameter ball heads and ball-and-socket joints is possible.

[0084] Similarly, in the human-shaped doll B, the joint ball heads with the same diameter can be replaced and spliced.

[0085] For figure A and figure B, joint ball joints with the same diameter can be interchanged between figure A and figure B. For example, the thigh of figure B can be connected to the shoulder joint of figure A using a 4.9 mm diameter ball joint. Holes with the same inner diameter can be interchanged between figure A and figure B. For example, the hole column in the calf of figure B can be connected to the hole in the upper arm of figure A.

[0086] It is also possible to connect joint balls and holes of the same size. For example, the upper part of the forearm component of humanoid doll A is inserted into the hole with an inner diameter of 3.4 mm in the upper arm component, and then connected to the hole with an inner diameter of 3.4 mm in the lower part of the thigh component of humanoid doll B, so as to realize the conversion of the wrist joint ball head with a diameter of 3.4 mm at the lower part of the forearm component of humanoid doll A to the ball socket with a diameter of 4.9 mm at the upper part of the thigh component of humanoid doll B.

[0087] The plugging and unplugging sequence of the present invention is described below through preferred examples.

[0088] The arm limb part has an arm sequential plug-in and pull-out joint, which is an arm sequential plug-in and pull-out joint extending from the shoulder joint along the arm limb part to the palm, and has multiple joints including the shoulder joint and the wrist joint with the plug-in and pull-out forces decreasing successively; preferably, it has multiple joints including the shoulder joint, the elbow joint and the wrist joint with the plug-in and pull-out forces decreasing successively.

[0089] The leg limb part has a leg sequential plug-in joint, which is a direction extending from the hip joint along the leg limb part to the sole of the foot, and has multiple joints including the hip joint and the ankle joint with the plug-in force decreasing successively; preferably, it has multiple joints including the hip joint, the knee joint and the ankle joint with the plug-in force decreasing successively.

[0090] In the sequential insertion and extraction joints of the arms, the undercut amount of the ball socket decreases from the shoulder joint along the direction of the arm limb to the palm; in the sequential insertion and extraction joints of the legs, the undercut amount of the ball socket decreases from the hip joint along the direction of the leg limb to the sole. This achieves a sequential reduction in the insertion and extraction force of the joints. In one variation, the sequential reduction in the insertion and extraction force of the joints is achieved by sequentially reducing the amount of interference between the ball socket and the ball head. In another variation, the sequential reduction in the insertion and extraction force of the joints is achieved by sequentially reducing the sum of the effects of the interference and the undercut between the ball socket and the ball head.

[0091] The insertion and removal force of the ankle joint is smaller than that of the knee joint, the insertion and removal force of the knee joint is smaller than that of the hip joint, and the insertion and removal force of the hip joint is smaller than that of the waist joint; wherein, the two ends of the knee joint are respectively connected to the thigh and the calf, or, the two ends of the knee joint are respectively connected to the longer upper thigh and the shorter lower thigh, or, the two ends of the knee joint are respectively connected to the shorter upper calf and the longer lower calf.

[0092] The insertion and removal force of the wrist joint is smaller than that of the elbow joint, the insertion and removal force of the elbow joint is smaller than that of the shoulder joint, and the insertion and removal force of the shoulder joint is smaller than that of the waist joint; wherein, the two ends of the elbow joint are respectively connected to the upper arm and the forearm, or the two ends of the elbow joint are respectively connected to the longer upper arm and the shorter lower arm, or the two ends of the elbow joint are respectively connected to the shorter upper forearm and the longer lower forearm.

[0093] The insertion and extraction force of the neck joint is smaller than that of the ankle joint;.

[0094] In more preferred embodiments, the multiple joints of the arm limb components use ball heads with the same diameter; the undercut of the ball and socket of the joints of the arm limb components decreases from the shoulder joint along the direction extending from the arm limb component to the palm; the multiple joints of the leg limb components use ball heads with the same diameter; the undercut of the ball and socket of the joints of the leg limb components decreases from the hip joint along the direction extending from the leg limb component to the sole of the foot. In this way, when the user pulls off the palm component, only the palm component will be detached from the forearm component, and the palm component will not cause the forearm component to be detached from the upper arm component, nor will the palm component cause the forearm component or the upper arm component to be detached from the shoulder joint. Similarly, when the user pulls off the sole component, only the sole component will be detached from the calf component, and the sole component will not cause the calf component to be detached from the thigh component, nor will the sole component cause the calf component or the thigh component to be detached from the hip joint. Furthermore, when the user replaces parts, the assembled parts will not be accidentally disassembled. The joints of the arm limb parts include shoulder joints and wrist joints. The shoulder joints and wrist joints use universal ball heads with the same diameter, and the ball socket of the shoulder joint is larger than the ball socket of the wrist joint; the joints of the leg limb parts include hip joints and ankle joints. The hip joints and ankle joints use universal ball heads with the same diameter, and the ball socket of the hip joint is larger than the ball socket of the ankle joint.

[0095] When the sole of the human-shaped doll, for example, a sole in the shape of a shoe, is attached to the base, when the user removes the head of the human-shaped doll, the insertion and removal force of the neck joint is less than the insertion and removal force of the ankle joint. Therefore, the head of the human-shaped doll will be removed while the ankle joint remains attached, thereby preventing the calf component and the sole from being accidentally removed.

[0096] Regarding the insertion and extraction force of the ball head and socket, the present invention standardizes the size of the ball head, and obtains different joints with different insertion and extraction forces by making different undercut structures of the ball socket at different joints. Since the height of the human-shaped doll itself is relatively small, the ball head diameter and the undercut structure of the ball socket are both tiny structures, which are prone to errors in production. The errors in the ball head size and the errors in the undercut structure of the ball socket are superimposed, resulting in a large error in the insertion and extraction force. The present invention adopts a universal ball head, and only needs to meet the dimensional relationship between the undercut structures of the ball socket of different joints to achieve a sequential reduction in the insertion and extraction force, thereby reducing the requirements of the manufacturing process on the ball head error and the superimposed error between the ball head and the ball socket.

It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. The embodiments of this application and the features in the embodiments may be combined with each other in any manner unless there is a conflict.
