DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 a , 2 a , 3 , and 5 a , there is shown a double layer block structure constructed in accordance with the invention. The original structure is a disc. The structure comprises four single layer blocks 1 , two first double layer blocks 21 , two second double layer blocks 22 , four outer stickers 31 , and four inner stickers 32 . An upper layer section of the structure comprises two single layer blocks 1 , two upper layers 211 of two first double layer blocks 21 , and two upper layers 221 of two second double layer blocks 22 . A lower layer section of the structure comprises the other two single layer blocks 1 , two lower layers 212 of two first double layer blocks 21 , and two lower layers 222 of two second double layer blocks 22 . The outer stickers 31 are adhered to the top and bottom surfaces of the structure. The inner stickers 32 are adhered between the upper layer section and the lower layer section of the structure. FIG. 2 a is a perspective view of the assembled structure in the first shape. The structure is able to upwardly turn either about two parallel axes 4 on the top surface or about two axes 4 on the bottom surface (as detailed later) since the outer stickers 31 are adhered to the top and bottom surfaces of the structure. The single layer blocks 1 of the lower layer section turn from a folded line 5 perpendicular to the axes 4 to form as a second shape as the first double layer blocks 21 and the second double layer blocks 22 turn about axes 4 respectively (see FIG. 2 b ). The axes 4 of the upper layer section and the lower layer section can be seen in the second shape. However, it is impossible to divide the structure into two portions from the folded line 5 opposite the axes 4 if the structure is turned about the axis 4 in the lower layer section. That is, it is only allowed to turn about the axis 4 in the upper layer section to form as a third shape (see FIG. 2 c ). Next, it is possible to change the axis 4 to form as a fourth, fifth, sixth, seventh, or eighth shape (see FIGS. 2 d to 2 h ). The structure can change from the first shape to the eighth shape directly by turning. This is best illustrated in FIGS. 1 a to 1 h , which are exploded views of a first preferred embodiment of double layer block structure according to the invention.

In the first, third, fifth, or seventh shape, it is possible to change the axis 4 . In other words, it is possible to not only change into the second, fourth, sixth, and eighth shapes by turning but also to return to the eighth, second, fourth, and sixth shapes by turning. FIGS. 2 a and 6 show the structure in the first shape. The structure will form the second shape by turning about the axis 4 in FIG. 2 a . Alternatively, the structure will form the eighth shape by turning about the axis 4 in FIG. 6 .

Referring to FIGS. 4 a and 4 b , which are perspective views showing the sticker to be adhered to the blocks in the seventh and eighth shapes respectively. FIG. 4 c is a perspective view of the expanded sticker shown in FIG. 3 .

FIGS. 7 a to 7 d are perspective views of a second preferred embodiment of a double layer block structure according to the invention for illustrating first, second, third, and fourth shapes thereof respectively. In this embodiment, the original structure is a parallelepiped having a square shape viewed from either the top or the bottom. The turning direction of the second embodiment is opposite to that of the first embodiment. But both can turn repeatedly. Also, different combinations of the inner stickers and the outer stickers can be formed in different shapes by turning in either embodiment.

While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
