Abstract

A spheric puzzle includes a plurality of slidable members (12,14), and a plurality of rails (2). The slidable members form a hollow sphere. Each of the sides of each of the rails (2) is slidably mounted between the corresponding sides (222) of two adjacent slidable members (12,14).

Description

BACKGROUND

1. Field of the Invention

The present invention relates to magic cubes, and particularly to a spheric magic tube.

2. Background of the Invention

A puzzle device which is highly popular is that sold under the trademark RUBIK'S CUBE in which a main cube is divided into groups of minor cubes of nine cubes disposed three by three along each face of the main cube. Each of the groups of cubes is independently rotated about an axis perpendicular to the plane of the group. The axes of the groups being othorgonally related. The faces of the minor cubes are variously colored and it is the general object of the puzzle to successively rotate the groups about their respective axes from a random arrangement of the minor cubes to a condition wherein the minor cubes achieve a predetermined arrangement, for example with the faces of the minor cubes in a group being of the same color.
Currently, there're two types of Magic cubes. One is cubic, and the other is spheric. Groups of the cubic type of Magic cubes can rotate only in two directions. Groups of the spheric type of Magic cubes can rotate in three directions, such as Hungarian-Globes, Magic Balls, K-Ball, and so on. However, parts of each group of the Magic cubes could not disassembled. Thus, it is inconvenient in using the Magic cube.
What is needed is to provide a spheric magic tube which is convenient to be used.

SUMMARY

A exemplary spheric Magic cube includes a plurality of slidable members, and a plurality of rails. The slidable members form a hollow sphere. Each of sides of each of the rails is slidably mounted between corresponding sides of two adjacent slidable members.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an exploded, isometric view of a group of a spheric Magic cube in accordance with a preferred embodiment of the present invention, the Magic cube includes a plurality of groups of slidable members, rails, shafts, and decorating slices;
FIG. 2 is an isometric view of the slidable members of FIG. 1; and
FIG. 3 is an isometric view of the rails and the shafts of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGs. 1 to 3, a spheric Robik's cube in accordance with a preferred embodiment of the present invention includes eight triangular and cambered slidable members, twelve long and cambered rails 2, six shafts 3, and a plurality of decorating slices 4. The slidable members enclose a hollow sphere. The rails 2 are located between every two adjacent slidable members. The shafts 3 are located between corners of the slidable members. Three decorating slices 4 are mounted to each slidable member. The decorating slides 4 are colored.
Each slidable member includes an inner slidable member 12, an outer slidable member 14, and a bracket 16. The inner slidable member 12 and the outer slidable member 14 are mounted together via the bracket 6. The inner slidable member 12, the outer slidable member 14, and the mountable bracket 16 can be mounted together by screws or rivets. Each side of the inner slidable members 12 defines a slot 122 therein.
Each rail 2 has a T shape. The rail 2 includes a body 22, connecting portion 24 extending inwardly from a lengthwise center of the body 22, and a pair of hooks 222 extending downwardly from opposite lengthwise sides of the body 22. Each of the brackets 16 has three arms (not labeled) perpendicular to one another.
Each shaft 3 includes a pair of tabs 32 and 34 extending from a circumference of the shaft 3. A receiving slot 36 is defined between the tabs 32 and 34. Each decorating slice 4 includes a plurality of protrusions 42 extending inwardly therefrom for engaging with a corresponding outer slidable member 14.
In assembly, hooks 222 of the rails 2 are placed between inner slidable members 12 and the corresponding outer slidable members 14. The bracket 16 is placed to an inner surface of the inner slidable member 12. Each bracket 16, a corresponding inner slidable member 12, and a corresponding outer slidable member 14 are mounted together by screws or rivets (not shown). Edges of the rails 2 are slidably located between the inner slidable member 12 and the corresponding outer slidable members 14. The hooks 22 of the rails 22 are slidably engaged in the slots 122 of the inner slidable members 12. Ends of each of the bracket 16 are mounted to three rails 2 that are perpendicularly to one another. Each shaft 3 is located among ends of the corresponding rails 22. Thus, a hollow sphere is shaped. The decorating slices 4 can be mounted to an outer surface of the outer slidable members 14 to decorating the sphere. The Magic cube can slide along three rails. The rails are perpendicular to one another. In work, edges of the inner slidable members 12 can slide through the receiving slots 36 of the shafts 3.
Furthermore, the slidable members can be connected by ribs and dents between two adjacent slidable members. Numbers of the decorating slices can be 1, 2, or 4, and so on. And different colors of decorating slices can be replaced.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
