Description

Joint, snap device having the joint, and combination thereof

The present invention relates to a joint and a buckle device, and more particularly to a joint for a toy building block, a snap device having the joint, and an assembly thereof.

In combination toys, joints are often used to connect different blocks so that the blocks are connected to each other in various degrees. Referring to Figure 1, a joint is disclosed that includes a first pivot 11 and a second pivot 12. The first pivot shaft 11 includes a shaft portion 111. The second pivot 12 is pivotally coupled to the shaft portion 111 to enable the second pivot 12 to rotate relative to the first pivot 111. Such a joint can only adjust the angle between the first pivot 11 and the second pivot 12, and the degree of freedom of rotation is too small to meet the needs of various angles.

Referring to Fig. 2, in the conventional combination toy, if only various parts are simply connected, it is possible to use only one push-type snap group without using the joint. The push-on buckle set includes a female fastener 13 and a male fastener 114. The female fastener 13 includes a plurality of circular through holes 131. The male fastener 14 has a cylindrical body 140 and a rim 141 formed on the outer surface of the body 140. The rim 141 separates the body 140 from the insertion portion 142 extending from the rim 141 to both opposite ends. One of the insertion portions 142 can be inserted into the through hole 131 of the female fastener 13 to complete the fastening action, and the other The plug portion 142 is engageable by the other sub-part 10. However, since the insertion portion 142 engaged in the through hole 131 can be rotated, when the sub-assembly 10 is mounted on the other insertion portion 142, the sub-part 10 can be rotated around the through hole 131. The combination is less stable. Moreover, the volume of the male fastener 14 is relatively small. When the male fastener 14 is to be disassembled, it is difficult to find a suitable force application position, and the disassembly is relatively difficult.

With regard to the above-mentioned problem that the disassembly is not easy, a related solution has been proposed. Referring to FIG. 3, a groove 143 is formed on the male fastener 14. When the male fastener 14 is mounted on the female fastener 13, A wrench (not shown) is used to penetrate the slot, and the male fastener 14 is biased to pull off the female fastener 13. However, the aforementioned male fastener 14 is substantially cylindrical, so the stability of the joint still has room for improvement.

Therefore, the object of the present invention is to provide a joint that can rotate in multiple directions.

Thus, the novel joint includes: a ball seat, an inner ball shell, a pivot ball, and a shaft.

The tee includes an axis of rotation.

The inner spherical shell is rotatably disposed in the spherical seat and engages the spherical seat, and is rotatable relative to the spherical seat about the rotational axis.

The pivoting ball is rotatably disposed in the inner spherical shell and engages the inner spherical shell and includes a spin axis perpendicular to the rotation axis. The pivoting ball can drive the inner spherical shell to rotate together around the spin axis.

The shaft includes a first end connected to the pivoting ball, and a Extending along the spin axis, a second end of the ball seat, the shaft can drive the pivoting ball to rotate relative to the inner spherical shell about the spin axis, and can drive the pivoting ball and the inner spherical shell Rotate together about the axis of rotation.

The function of the present invention is that the shaft can rotate around the spin axis in the inner spherical shell, and the shaft can further rotate the inner spherical shell to rotate around the rotating axis through the pivoting ball, so that the shaft The rod exhibits multiple directions of rotation relative to the tee.

Another object of the present invention is to provide a snap device that combines stability and can be rotated in multiple directions.

Therefore, the novel buckle device comprises: a joint as described above, and a push-type buckle group.

The push-on buckle set includes a first female fastener and a male fastener.

The first female fastener is mounted on one of the shaft and the ball seat and has at least a consistent hole. The through hole has a first opening and a second opening which are opposite and polygonal, and a small aperture section connecting the first opening and the second opening. The aperture of the small aperture section is smaller than the first opening and the second opening. The first female fastener further has a first stop surface defining the first opening and a second stop surface defining the second opening.

The male fastener includes a body portion, a first ring edge and a second ring edge spaced apart from each other and surrounding the outer surface of the body portion. The first rim separates the body portion from a first fastening segment extending from the first rim to one end of the body portion. The first fastening segment can penetrate the small aperture segment from the first opening and limit the male fastener by the first annular edge abutting against the first blocking surface .

The effect of the present invention is that the first ring edge and the first opening are matched polygons, so that the first ring edge is engaged with the first opening edge and is restrained by the first blocking surface, thereby The male fastener cannot be rotated arbitrarily, and the combination is more stable.

A further object of the present invention is to provide an assembly snap device that is robust, easy to disassemble, and capable of multi-directional rotation.

Thus, the novel assembly includes a snap device as described above, and a seesaw.

The raft can be inserted between the first rim and the second rim, and can be applied to the second rim to disengage the male fastener from the first female fastener.

The utility model has the advantages that the first rim and the second rim are spaced apart to allow the sill to be inserted therebetween, and the second rim is easily biased to force the male fastener Since the first female fastener is detached, the disassembly is very easy.
