Abstract
Disclosed is a joint assembly for dolls for connecting two limb portions. A first joining surface and a second joining surface are disposed at a connecting position of the limbs and a first embedding hole and a second embedding hole are formed at the center of the first joining surface and second joining surface respectively, and an expanding portion is formed and extended inwardly along an opening of each of the embedding holes for inserting an embedding column with circular protrusions at both ends, so as to improve the convenience of installation. The circular protrusions and the expanding portions can improve the smoothness of movement and prevent the limb portions from falling out.
Claims18
A joint assembly for dolls, for connecting a plurality of limb portions and setting two adjacent limb portions at a movable state, comprising:
- a first joining surface, being a planar surface formed at a connecting position of one of the limb portions, and having a first embedding hole formed at the center of the first joining surface and having a diameter ø1, and a first expanding portion with a diameter ø2 being formed and extended inwardly along an opening of the first embedding hole to a bottom of the first embedding hole, and ø2>ø1;
- a second joining surface, being a planar surface formed at a connecting position of the other limb portion, and disposed opposite to the first joining surface, and having a second embedding hole with a diameter ø3 formed at the center of the second joining surface, and a second expanding portion with diameter ø4 being foimed and extended inwardly along an opening of the second embedding hole to a bottom of the second embedding hole, and ø4>ø3;
- and
- an embedding column, having a first circular protrusion and a second circular protrusion with a diameter ø5 of disposed at both ends of the embedding column respectively, and a column body with a diameter ø6 formed at the center of the embedding column and being substantially in a cylindrical shape, and ø5>ø6, and ø02=ø4≧ø5>ø1=ø3;
- during assembling, both ends of the embedding column are inserted into the first embedding hole and the second embedding hole respectively, such that the first circular protrusion and the second circular protrusion are movably snapped into the first expanding portion and the second expanding portion respectively, and the first joining surface and the second joining surface are attached with each other to provide a frictional force for the purpose of positioning after turning the limb portions.
