Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molecular structure model capable of visually and three-dimensionally producing a molecular structure.

[0002]

2. Description of the Related Art Generally, in order to visually understand a molecular structure model, there is a molecular structure model in which a plurality of atom models made of plastic are combined to represent a molecular structure in three dimensions. As shown in FIG. 9, for example, a conventional molecular structure model has a plurality of holes 2 on the surface of a polygon 1 such as a tetrahedron or an octahedron.
An atomic model 3 provided with a hole, an atomic model 5 provided with a hole 2 on the surface of a sphere 4, and a connecting rod 6 are combined to form a molecular structure model.

However, in this structure, the atomic model 3 does not correspond to a specific element, and has a constant size so as to be able to correspond to an arbitrary element. As shown in FIG. However, unlike the actual molecular structure, an accurate structure could not be represented. In addition, since the connecting portion between the atomic models 3 and 5 and the connecting rod 6 can rotate freely, the bond angle is not fixed and not only cannot reproduce the actual molecular structure but also a molecular structure that is theoretically impossible. There was also a problem of being created.

In addition, as shown in FIG. 11, an atomic model 10 having a projection 7 and a cylindrical portion 8 protruding at a predetermined angle on the surface of a sphere 4 and a cylindrical portion 8 on the surface of the sphere 4 are formed. In some cases, the atomic model 11 is combined and the protrusion 7 is inserted into the cylindrical portion 8 to form a molecular structure model as shown in FIG.

In this structure, the bond angle of the atomic model 10 is defined, but the rotation of the atomic models 10 and 11 connected to the atomic model 10 is free, so that an accurate structure cannot be represented and the bonding strength is weak. There is. The sphere 4 of the atomic models 10 and 11
Since the sizes are the same and do not correspond to the sizes of the elements, it was not possible to reproduce the actual molecular structure, and it was troublesome to create a molecular structure model of a protein or amino acid having a complex sequence.
