## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to toy model assembly kits, and more particularly to a planar-part-based toy assembly set composed of a plurality of planar parts that have different shapes and are made by stamping a planar material board using a stamping machine, wherein each of the planar parts can such couple with an adjacent planar part that the two coupled parts are allowed to swing with respect to each other or are fixed at a specific angle with respect to each other. In this manner, the planar parts can be assembled into a three-dimensional structure that can be posed to present different postures.
2. Description of Related Art
There are various toy model assembly kits available on the market, such as robot model assembly kits, animal model assembly kits and so on. For making these toys more interesting, the manufacturers usually provide parts of such a toy model assembly kit with joints that, when combined together, have their joining angle adjustable, thereby endowing the assembled models to change postures and thus be more realistic. However, since these existing posture-changeable model toys need structurally complicated parts, particularly the joint parts that allow their joining angle to be adjustable, the manufacturing costs are relatively high.
SUMMARY OF THE INVENTION
In view of this, the present invention provides an inexpensive, interesting and kaleidoscopic planar-part-based toy assembly set.
In other words, the primary objective of the present invention is to provide a planar-part-based toy assembly set composed of a plurality of planar parts that have different shapes and are made by stamping a planar material board using a stamping machine, wherein each of the planar parts can such engage with an adjacent planar part that the two engaged parts are allowed to swing with respect to each other or are fixed at a specific angle with respect to each other. In this manner, the planar parts can be assembled into a three-dimensional structure that can be posed to present different postures.
To achieve the foregoing objective, the present invention adopts the following technical means.
In the present invention, the planar-part-based toy assembly set comprises a plurality of planar parts that have different shapes and are made by stamping a planar material board using a stamping machine, and the planar parts includes at least one body piece and at least one limb piece.
The body piece is provided with at least one slotted ring that is configured to engage with the limb piece and connect the body piece and the limb piece together, wherein a cutting slot is provided at an outer side of the slotted ring, and the slotted ring has a circular enclosure including a narrow section and a wide section.
The limb piece is provided with at least one closed ring, or at least one slotted ring structurally similar to the slotted ring of the body piece.
The closed ring has an inner diameter greater than a width of the narrow section of the slotted ring and smaller than a width of the wide section of the slotted ring.
The closed ring of the limb piece can be mounted around the narrow section or the wide section of the slotted ring of the body piece through the cutting slot at the outer side of the slotted ring of the body piece, thereby connecting the limb piece and the body piece together.
The closed ring of the limb piece can be mounted around the narrow section or the wide section of another limb piece through the cutting slot at the outer side of the slotted ring of the second limb piece, thereby connecting the limb piece and the second limb piece together.
When the closed ring is mounted around the narrow section, the limb piece is allowed to swing. When the closed ring is mounted around the wide section, the limb piece is fixed at a specific angle, which can be later adjusted by the player as desired.
In manufacturing, the body piece may be provided with the closed rings, and the limb piece may be provided with both the slotted rings and the closed rings, so as to enhance the overall assembling variability of the toy.
When plural body pieces and plural limb pieces are assembled together, with the combination of the slotted rings and the closed rings as described previously, the joining angle between adjacent body piece and limb piece, or between the adjacent two limb pieces can be adjusted, allowing the assembled toy to be a posture-changeable three-dimensional structure, with each said limb piece angularly changeable, thereby significantly enhancing the assembling variability and fun.
