Bone-like construction for toy doll and the doll having the same construction
A toy doll has a bone-like construction, wherein the toy doll can freely take a yieldable attitude even if its arm or its leg is deeply bent on its joint. The toy doll is equipped with an intermediate and auxiliary joint in the upper arm and in the thigh which does not exist in a human being. The toy doll can obtain any curving attitude either for maintenance or for release because of the flexibility of the intermediate and auxiliary joint located in an arm or leg bone.

BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a bone-like construction for a toy doll and the doll having the same construction, wherein an arm which is devised to have an upper arm bone equipped with a joint on each end like a human being and a leg which is devised to also have a thigh bone with a joint on each end.
2. Description of the Prior Art
In the prior art, various kinds of toy dolls were assembled with bone-like materials having joints and skin-like materials. The skin-like materials covered the bone-like materials like a human being wherein the dolls were provided in deformable and yieldable forms by movement of the equipped joints.
Similarly, the dolls were provided with their covers constructed of flexible materials and with bone-like materials inside and pad materials there between, wherein deformable joints like a human being are equipped with the bone-like materials. At the same time, a figure doll was also marketed wherein a bone constructed of hard materials was covered with a soft skin while movable joint portions were equipped with the bone like a human being so that the joint portions were always arranged to remain at neutral positions.
SUMMARY OF THE INVENTIONBone-like constructions for an arm and a leg for a doll adopted by prior arts were composed of arm bones and leg bones with joints on both ends similar to the construction of a human being. Arm portions and leg portions for the doll were covered with outer covers composed of soft resin similar to human skin. When an elbow joint of the doll is gradually bent, each cover of an upper arm and a forearm approaches together in the vicinity of the elbow joint and friction power is caused thereon so that wrinkle is created on the friction point. Thus, this wrinkle creation prevents the doll from bending attitude and the required condition to keep bending cannot be maintained. At the same time, the above theory can be true of the leg portions of the doll. When a knee joint of the doll is bent, each cover of a thigh and a lower leg approaches together in the vicinity of the knee joint to invite the wrinkle creation on the knee joint by the friction power. Because of this result, maintenance of the knee bending is lost.
In view of above difficulty, the present invention has an object to provide the bone-like construction for the doll which maintains its attitude for the bending on the point of the elbow joint or that of the knee joint even if the doll is deeply bent on each joint point.
In order to overcome the difficulty, the present inventor has repeated many trials and errors through his various experiments by producing many models or samples for toy dolls. After these experiments, he discovered provision of a novel intermediate joint in the bone-like construction at each end of the upper arm bone or the thigh bone. Although the intermediate joint does not exist in a human being, this intermediate joint can soften some strong approach between each cover on the joint point, whereas the maintenance of bending attitude can be maintained.
The bone-like construction developed by the present invention has the arm bone and the log bone, and on each end of these bones the joints are prepared. On the middle of these bones are the intermediate and auxiliary joints which divide the bones for bending. These intermediate joints do not exist in a human being.
The intermediate joint comprises a joint surface which is established on the divided face of the bones with each other contacted, a pivot point about which operates the joint surface to be separated or to be contacted, and a holder which is set rotatably to the pivot point and suspends separation of the joint surface with a fixed angle.
The bones of the toy doll developed by this invention are produced in hard resin mold while the skin covers are produced by soft resin mold.
A toy doll having a bone-like construction wherein the doll has joints on both ends of arm portions or leg portions comprise a bone-like construction having an intermediate and auxiliary joint in a middle of the arm portions and/or leg portions so that the intermediate and auxiliary joint allows the bone to bend for yieldable poses, wherein the intermediate and auxiliary joint does not exist in a human being.
The bone-like construction according to claim 1, wherein the bone is produced similar to a human upper arm bone or a human thigh bone with the inclusion of the intermediate and auxiliary joint in the arm bone and the thigh bone.
The intermediate and auxiliary joint comprises a pair of joint surfaces which contact each other formed on parts of arm or leg bone portions; a pivot for said pair of joint surfaces wherein the surfaces are in contact or separated; and a holder rotatably fixed onto the pivot and adapted to hold separation of the two surfaces at a fixed angle.
The toy doll which has a bone-like construction where the toy doll can take poses in yieldable attitudes as desired, and the bone is a material selected from hard plastic resin while a skin cover wrapping the bone is a material selected from soft plastic resin.
