The construction set includes various sizes of limbs, heads, joints and hubs which are useable to form life like arms, legs, wings, necks, spines and tails of creatures, the variety of which is limited only by the child&#39;s imagination.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to toy construction sets and specifically to toy construction sets suitable for modeling animal, bird, insect, dinosaur and humanoid figures. 
     Over the years many different types of toy construction sets comprising a multiplicity of parts have been produced. The parts of the set may be assembled by the child in a large variety of ways. One example of this type of construction set is &#34;Lego&#34; brick-like blocks which have interlocking pegs and holes and which may be assembled into large structures. Another popular construction set toy is the &#34;Tinker-Toy&#34; which consists of wooden rods which fit into hubs in a hub and spoke arrangement which may also be used to construct a wide variety of structures. The play value of such construction sets is greatly enhanced by the fact that the child can use his or her own imagination to construct structures in a number of different forms and thereafter reuse the components to construct something different. 
     A disadvantage of the above described construction sets is that the type of structure that can be built is limited by the geometry of the particular construction set. Indeed both the Lego and Tinker Toy construction sets are best suitable for the modeling of inanimate objects, such as buildings and Ferris wheels, and are not particularly suitable for the modeling of animal or humanoids because of their fixed joints. The present invention is directed to overcoming these disadvantages and to providing a toy construction set that is particularly suitable for the construction of animate objects such as animals, birds, insects, dinosaurs and humanoids (robots, monsters and people). 
     The present invention is directed to a construction set that is particularly adapted for the modeling of animate objects and particularly to objects having bones, joints and limbs (e.g. vertebrates). To this end the individual components of the construction set are analogous to bones and moveable joints. The construction set includes various sizes of limbs, joints and hubs which are useable to form life like necks, spines and tails of creatures whose design is limited only by the child&#39;s imagination.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 illustrates the first component of the construction set of the present invention. The first component is a long bone 10 which has an elongated shaft portion 11 and end flanges 12, 13. Extending from flange 12 is a connecting post 16 and extending into flange 13 is a connecting socket 17. The portions of shaft 11 proximate to flanges 12,13 include flares 18 which provides strength and stability as well as lending an attractive bone-like appearance to shaft 11. Connecting socket 17 is designed to receive, with a friction fit, the connecting post of another component and connecting post 16 is designed to fit into the connecting sockets of the other components with a friction fit. In this manner each of the components may be joined to each other as the connecting socket and connecting post dimensions are standardized. Preferably the dimensions of the connecting posts and connecting sockets of the present construction set are the same as the connecting posts and connecting sockets of Lego blocks, so that Lego blocks and accessories can be used in conjunction with the components of the present construction set. 
     Another component part shown in FIG. 2 is a short bone 20 which has a shaft 21 which is shorter than that of shaft 11 of bone 10. Short bone 20 includes flanges 22,23; a connecting post 26 and a connecting socket 27. Shaft 21 also has flares 28 leading to flanges 22,23. As with all of the components of the present construction set, connecting post 26 and connecting socket 27 are of the standard dimensions. A small bone 30 shown in FIG. 3 forms another bone like component. Small bone 30 includes a short, narrow shaft 31 and end portions 32,33. End portions 32,33 of small bone 30 are sized and configured to have the same dimensions as the standard connecting posts of the other components, thus end portions 32,33 can be inserted into any standard connecting socket. 
     In order to connect more than two components of the construction set together, as well as to connect components transversely, a small hub 35 shown in FIG. 4 and a large hub 40 shown in FIG. 5 are provided. Small hub 35 has a body portion 36 and three connecting sockets 37 extending radially outwardly. Connecting sockets 37 are of the standard size to receive the connecting posts of the other components. Small hub 35 may be used to provide a Y branching of the other components. Large hub 40 includes a body portion 41 and three radially extending connecting sockets 42. Body portion 41 of large hub 40 includes an opening 43 which will receive the inserts and connectors described below. 
     In order to provide connections and extensions to large hub 40 an insert connector 50 shown in FIG. 6 and a male connector 55 shown in FIG. 7 are provided. Insert 50 includes a cylindrical body portion 51 which is sized to be a friction fit in opening 43 of large hub 40. Extending from the upper part of body portion 51 of insert 50 is a connecting post 52 with a connecting socket 53 disposed in the lower surface. Male connector 55 has a cylindrical body portion 56 sized to be inserted in opening 43 of large hub 40. The connecting posts 57 and 58 extend from the upper and lower flat surfaces of body portion 56 of male connector 55. Male connector 55 can also serve as a female to male gender changer. Thus by the use of inserts 50, or male connectors 55, a series of large hubs 40 may be stacked together with other components inserted into its connecting sockets 42. 
     An essential requirement for modeling a vertebrate is to provide for moveable joints, to this end the present construction set provides a number of moveable joint components. The first such component is a large joint 60 shown in FIG. 8 which includes a cup portion 61 for movably receiving a ball portion 62. Cup portion 61 includes a semi spherical concave recess 63 and U-shaped notches 64 in its forward and rearward walls. Recess 63 is designed to extend around more than half of ball portion 62 so as to retain same. This configuration also makes it difficult, if not impossible, for a child to disassemble cup portion 61 from ball portion 62. U-shaped notches 64 provide clearance to permit large pivoting angles of more than 90° between cup portion 61 and ball portion 62 and to permit cup portion 61 to &#34;stretch&#34; to permit ball portion 62 to be inserted during manufacturing. 
     A flat surface 65 on cup portion 61 forms a flange from which a connecting post 66 extends. Ball portion 62 includes a flat surface 67 which has a connecting socket 68. Thus when large joint 60 is used to join two components the components may be pivoted with respect to one another in any desired plane. In this regard flat surface 67 is sized such that it is smaller than the distance between the arms of U-shaped notches 64. Preferably one or both of the abutting surfaces of ball portion 62 and cup portion 61 are roughened to assure a good friction fit, so that the angular position set by the user will not slip due to the weight of the attached components. 
     Another joint component is a small joint 70 shown in FIG. 9 which is comprised of a small cup portion 71 and a small bone portion 72 which has at one end a small ball 73. Ball 73 and cup portion 71 are similar to, but smaller in diameter, than large joint 60. The free end of cup portion 71 includes a connecting socket 74 and has U-shape openings 75 on each side which provides clearance to permit portion 72 to be pivoted more than 90° with respect to small cup portion 71. Small bone portion 72 has a connecting post 76 at its free end and a flared section 77 at the end proximate to ball 73. As was the case with large joint 60, cup portion 71 is constructed to surround more than half of ball 73 so as to retain it and to make it difficult for a child 10 to disassemble cup portion 71 from small bone 72. The confronting ball and cup surfaces may also be roughened so as to maintain a set position. 
     FIG. 10 shows a &#34;clawball 80&#34; which has a cup portion 81 and a claw portion 82 which has a ball 83 at one end. Cup portion 81 is basically the same as cup portion 71 and includes a connecting socket 84 and U-shaped openings 78 on each side which provides clearance to permit portion 82 to be pivoted more than 90°. Cup portion 81 is also constructed to surround more than half of ball 83 so as to retain it and to make it difficult for a child to disassemble. 
     FIG. 11 illustrates a toy &#34;head&#34; 85 which has an outer profile in the shape of an animal, dinosaur or other type of head. Head 85 includes a number of connecting sockets 86 to permit other components to be connected to it. A lateral edge of head 85 may also contain a connecting socket 87 to permit head 85 to be connected to other components forming a &#34;neck&#34;. Rather than connecting sockets 86, connecting posts could also be used on head 85, or a mixture of posts and sockets. The head component of course need not be made in the shape shown as it could be in a wide variety of shapes to model different creatures. Furthermore plates in other geometric shapes such as circles, squares and triangles could also be used with the present construction set. 
     FIGS. 12 and 13 illustrate another connector 90 which is pivotable in a single plane. Connector 90 includes a yoke portion 91 and a T-shaped pivoting portion 92. Yoke portion 91 includes a connecting socket 93 and loops 94 having circular openings 95 for pivotally receiving the cylindrical top part 96 of pivoting portion 92. Pivoting portion 92 also includes a connecting post 97 for connection to other components. 
     FIG. 14 shows certain of the components of the present construction set attached to a standard Lego building block 100. As can be seen the components of the present construction set which utilize connecting posts and sockets of the same diameter of the posts 102 of the Lego block 100 can directly connect to Lego pieces. In this manner Lego blocks can be used in creating the humanoid or animal figures, by way of example block 100 can form a &#34;foot&#34; for the figure. 
     FIG. 15 illustrates the above described components assembled to create a large insect like creature 110. As can be seen, the body segments of insect 110 are formed by large hubs 40 and large joints 60 with the eyes formed by large joints 60. The legs are formed from small joints 70, short bones 20, and large joints 60 joined by inserts 55. FIG. 16 shows a velociraptor 120 formed from the present construction set which utilizes head 85 and clawball 80. Velociraptor 120 illustrates how accurately a series of interconnected large joints 60 and large hubs 40 model the neck, spine and tail of the creature as they enable the modeling of life like curves. 
     The above described components may be made from many different types of materials. However, injection moldable relatively resilient plastics, such as polyethylene and polypropylene, are particularly suitable since they are inexpensive to manufacture. Furthermore a slight resilience also assures a good friction fit between the components. The use of resilient materials also permits to the dimension of the male components (such as connecting posts and the ball portions of joints) to be slightly larger than the female components (such as connecting sockets and the cup portions of joints). This will assure the components remain connected and in the set position while permitting removal and repositioning. Each component may also be molded in a different color to aid in assembly. 
     The invention has been described with respect to preferred embodiments. However, as those skilled in the art will recognize, modifications and variations in the specific details which have been described and illustrated may be resorted to without departing from the spirit and scope of the invention as defined in the appended claims.
