BACKGROUND OF THE INVENTION
Technical Field
The present invention relates to a dinosaur model with multi-joint assembly. More particularly, the present invention relates to a dinosaur model with multi-joint assembly that allows the user to grow his or her creative idea and pursue self-lead learning during the assemblage of relatively many parts into the finished article and which is designed to allow free modification of actions and to provide a definite anatomical structure of dinosaur during the sequential assembly of a skeletal frame having a joint structure and an integumental frame composed of separate a head, a neck, a trunk, legs, and a tail.
Background Art
Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, and were the dominant terrestrial vertebrates from the start of the Jurassic until the end of the Cretaceous. Also, the fossil record indicates the involvement of Pterosaurs and Ichthyosaur, which were flying reptiles, and large marine reptiles, respectively, as members of the clade Dinosauria.
The taxon Dinosauria, meaning ‘terrible reptile’, was formally coined by paleontologist Sir Richard Owen, who used it in August, 1841 in the Academic Research Development Meeting of England to express the great fossilized bones of Iguanodon found in 1825.
Collectively, dinosaurs as a clade are divided into two primary branches, Saurischia and Ornithischia, which are distinguished most noticeably by their pelvic structures, lizard- and bird-hipped joints, respectively. Saurischia includes the theropods, which are exclusively bipedal with a wide variety of carnivorous diets (e.g., tyrannosaurus, allosaurus, etc.), and sauropodomorphs, which are long-necked, quadrupedal herbivores (e.g., brachiosaurus, supersaurus, etc.). Ornithischia were primarily herbivores classified into four species including ornithopoda with long legs like birds, thyreophora with armor-like skins, ankylosauria with club-like tails, and ceratopsia with horns.
Such dinosaurian characteristics are very important factors by which dinosaurs can be distinguished from one another. Typically, students with an interest in dinosaurs learn the skill of distinguishing types of dinosaurs and widen their knowledge about dinosaurs through observation of fossilized bones.
Meanwhile, various models are fabricated and marketed for learning and studying skeletal structures of dinosaurs. Also, the models are prepared in the form of toys with the aim of arousing student interest, but conventional dinosaur models or toys have use limitations because they are provided as completely integrated forms.
Thus far, most dinosaurian models have been prepared as empty or latex-saturated figures that have rubber or plastic integuments or as wood or plastic puzzles, or limited to those composed of simple skeletal bones. Even though upgraded, those models are enabled only to do simple actions.
For example, Korean Patent Unexamined Application Publication No. 10-2003-0074580 (issued on 19 Sep. 2003) discloses a dinosaur toy having a skeletal frame composed of a spine, a tail, a head, forelegs and hind legs, a chest, a pelvis, and ribs. They are separate planar blocks, each having at least one concave fitting attachment, and can be assembled into or disassembled from the dinosaur model by fitting or detaching. Korean Utility No. 20-0434385 (issued 14 Dec. 2006) describes a dinosaur toy composed of blocks of main bones that can be assembled and move with the aid of motors and gears, thereby arousing an interest in dinosaurs and improving learning effects.
The conventional dinosaur models described above, however, have too small a number of assembly parts to allow the user to grow creative ideas and purse self-lead learning. In addition, the conventional models are limited in providing the user with accurate anatomical structures of dinosaurs because the parts have planar shapes and are designed to be simply fitted to each other for assembly.

Articulation between the pelvis member of the trunk skeleton unit 13 and the upper hind limb bone of the limb bone unit 15 is achieved by a ball and socket joint connection member (A; not in detail shown) that enables the bone members to move in all directions.
In addition, connection between the upper and the lower forelimb member of the limb bone unit 15 and between the upper and the lower hind limb member of the limb bone unit 15 is preferably accounted for by condylar joint connection member (E). Further, a hinge joint connection member (C′′) that permits motion in one direction accounts for connection between the lower forelimb bone member and the toe bone members in the limb bone unit 15. The hinge joint connection member (C′′) is also applied to the connection between the lower hind limbs bone member and the toe bone members in the limb bone unit 15.
As can be seen in FIG. 3, the skeletal frame 10 is preferably injection molded, together with the joint connection members described above, into a planar layer structure composed of many parts that is detachably integrated in a planar frame 10a. In addition, the skeletal frame 10 may be made of one synthetic resin selected from among a polypropylene resin, a polyethylene resin, and an ABS rein.

The integumental frame 20 is responsible for the general exterior of the dinosaur model, and includes a head integument unit 21 to be applied to the skull unit of the skeletal frame 10; a neck integument unit 22 to be applied to the cervical vertebra unit 12 of the skeletal frame 10; a trunk integument unit 23 to be applied to the trunk skeleton unit 13 of the skeletal frame 10; a tail integument unit 24 of the tail bone unit 14 of the skeletal frame 10; and a limb integument unit 25 to be applied to the limb bone unit 15 of the skeletal frame 10.
Moreover, the head integument unit 21 of the integumental frame 20 is composed of many separate head integument members that are preferably connected to each other by corresponding grooves and protrusions or by an engagement membrane. Likewise, the trunk integument unit 23 of the integumental frame 20 is composed of many separate trunk integument members that are preferably connected to each other by corresponding grooves and protrusions or by an engagement membrane. The tail integument unit 24 of the integumental frame 20 is composed of many separate tail integument members that are each of a conical frustum shape and which have such a curved end at rear region that they can move upon the fitting engagement of the cone. In addition, the limb integument unit 25 is composed of many separate leg integument members that are preferably connected to each other by corresponding grooves and protrusions or by an engagement membrane.
Particularly in the integumental frame 20, the integument members are preferably provided with groove and protrusion structures at sections thereof facing to each other so that they can be easily engaged and are not moved.
The integumental frame 20, as shown in FIG. 5, is preferably injection molded into a planar layer structure composed of many parts that is detachably integrated in a planar frame 20a. In addition, the integumental frame 20 may be made of one synthetic resin selected from among a polypropylene resin, a polyethylene resin, and an ABS rein. More preferred is a polypropylene resin because it is soft and suitable for painting.
When the dinosaur model with multi-joint assembly 1 is concerned with the flying reptile Pterosaur, preferably the limb bone unit 15 of the skeletal frame 10 comprises a wing bone part and the limb integument unit 25 of the integumental frame 20 comprises a wing part.
Between the skeletal frame 10 and the integumental frame 20 is positioned the connection member 30 that functions to connect the members of the skeletal frame 10 to those of the integumental frame 20. Preferably, the connection member has a rod shape with an “I” or “H” cross section, at opposite ends of which fitting protrusions are formed.
For connection therebetween by the above-described connection member 30, the members of the skeletal frame 10 and the integumental frame 20, as shown in FIGS. 6 and 8, are preferably provided with fitting grooves 16 and 26 to be fitted with fitting protrusions of the connection member 30.
As can be seen in FIG. 7, the connection member 30 is preferably injection molded into a planar layer structure composed of many parts that is detachably integrated in a planar frame 30a. In addition, the connection member 30 may be made of one synthetic resin selected from among a polypropylene resin, a polyethylene resin, and an ABS rein. More preferred is a polypropylene resin because of its high toughness and impact resistance.
In addition, the dinosaur model with multi-joint assembly 1 according to the present invention may further comprise an accessory or special ornament such as a horn, a cuirasse, a nail, a bump, etc. The accessory or ornament may be injection molded from a PC (polycarbonate) resin or a polystyrene resin. Preferred is a polystyrene resin in terms of injection process and cost.
For use in the injection molding into the skeletal frame 10, the integumental frame 20, and the connection member 30, the synthetic resins may preferably comprise 2 to 25 parts by weight of a far-infrared radiation-emitting and anion-generating ore powder per 100 parts by weight thereof respectively. The far-infrared radiation-emitting and anion-generating ore powder may be powdered from an ore selected from the group consisting of illite, sericite, mica, and muscovite.
When the far-infrared radiation-emitting and anion-generating ore powder is used in an amount of less than 2 parts by weight per 100 parts by weight of the resin, the emission of far-infrared radiation is minimal and the generation of anions is limited. On the other hand, more than 25 parts by weight of the far-infrared radiation-emitting and anion-generating ore powder may reduce the elasticity and ductility of the resin. Accordingly, the far-infrared radiation-emitting and anion-generating ore powder may be preferably used in an amount of 2 to 25 parts by weight per 100 parts by weight of the synthetic resin.
The far-infrared radiation-emitting and anion-generating ore powder improves the tensile strength and impact resistance of the injection molded products, that is, the skeletal frame 10, the integumental frame 20 and the connection member 30. Further, illite may bring about an effect of reducing the production cost when it is mixed with the expensive plastic resin.
The far-infrared radiation-emitting and anion-generating ore powder may range in particle size from 300 to 3,000 meshes, and preferably from 300 to 1,000 meshes in consideration of economical effects including production cost.
In another embodiment of the present invention, each of the skeletal frame 10, the integumental frame 20, and the connection member 30 is preferably injection molded from a composition comprising a weight part ratio of 100:2 ̃25:1 ̃3 of a synthetic resin:a far-infrared radiation-emitting and anion-generating ore powder:an inorganic ionic antibacterial agent. In this regard, so long as it exhibits inhibitory activity against E. coli and Pseudomonas aeruginosa, any inorganic ionic antibacterial agent can be used. Preferably, the antibacterial agent may be prepared by mixing 0.3 to 0.7 parts by weight of silver nitrate with 100 parts by weight of distilled water.
Before injection molding into the skeletal frame 10, the integumental frame 20 and the connection member 30 in an injector, chips of the selected synthetic resin material are loaded into an apparatus equipped with a stirrer, and melted at 200 to 250° C. and then stirred together with the far-infrared radiation-emitting and anion-generating ore powder with particle size from 300 to 1,000 meshes. If necessary, the organic ionic antibacterial agent may be added. In this context, the organic ionic antibacterial agent may be slowly added to the apparatus and stirred at a speed of 50 rpm for 5 min or longer.
Accordingly, while assembling into a miniature product the relatively many parts of the dinosaur model with multi-joint assembly 1 including parts constituting the skull unit 11, the cervical vertebra unit 12, the trunk skeleton unit 13, the tail bone unit 14, the limb bone unit 15 of the skeletal frame 10, the head integument unit 21, neck integument unit 22, trunk integument unit 23, tail integument unit 24, limb integument unit 25 of integumental frame 20, the connection members 30 for connecting the skeletal frame 10 and the integumental frame 20 to each other, and other joint connection members, users can stimulate their interest in dinosaurs and develop their spatial perception. Also, the user can grow creative ideas and pursue self-lead learning by coloring the integumental frame 20 to create a realistic model of a dinosaur.
Moreover, the dinosaur model with multi-joint assembly 1 according to the present invention is designed to allow free modification of actions and to provide a definite anatomical structure of dinosaur during the sequential assembly of the skeletal frame 10 having joint structures that enables various motions, and the integumental frame composed of separate body parts.
Being injection molded from a composition comprising a ratio of 100 wt parts:2 ̃25 wt parts of a synthetic resin:a far-infrared radiation-emitting and anion-generating ore powder, the dinosaur model with multi-joint assembly 1 of the present invention exerts various effects of far-infrared radiation. The dinosaur model with multi-joint assembly 1 prepared from a composition comprising a ratio of 100 wt parts:15 wt parts of a synthetic resin:a 300-mesh sericite powder of the present invention was measured for far-infrared emissivity and radiant energy, and the results are summarized in Table 1, below. The measurements were obtained relative to black mass using FT-IR spectrometer.
