Abstract

The utility model provides a rhombus jig-saw puzzle, which comprises a plurality of rhombus jig-saw puzzles. The thickness of base splitting plates of each rhombus jig-saw puzzle is the same, the base splitting plates are diamond flat plates with the same side length, and the top angle is the integrative times that pi is divided by n and the n is equal to 3, 4, etc. The splitting methods have various changes to split vivid patterns to fit the body and mind and intelligent exercising requirements for adults and children with excellent intelligence.

Description

Rhombus jig-saw puzzle

The utility model relates to the planar jigsaw puzzle toy, and particularly the basic jigsaw of a class is shaped as the jigsaw puzzle of specific rhombus.

In the existing planar jigsaw puzzle toy, risk the jigsaw puzzle of color graphics with versicolor quadrangle jigsaw, the jigsaw shape that is adopted mainly is the identical squares of some sizes.During amalgamation, each square jigsaw is formed a grid square on basal plane, and the formation of figure only realizes by the change color of jigsaw, and does not have the variation of jigsaw spelling.The toy of for example common insertion plastics in the lattice eye of a square grid or wooden colored rectangular inserted block, or the picture mosaic of colored square ceramic tile etc.Because the outline line of figure is limited in changing in the grid square, so the amalgamation function is extremely limited, the figure that amalgamation goes out is not true to nature, lacks interest and challenge, and adult and the higher children of intelligence are not had attraction.

The purpose of this utility model provides a class combination method extremely changeableization, and the novel planar jigsaw puzzle toy that the amalgamation figure is more true to nature is to adapt to the needs of adult or the higher children's pleasant mental and body of intelligence and exercise intelligence.

The purpose of this utility model reaches by following technical proposals: this class rhombus jigsaw puzzle can have many kinds, the basic jigsaw of each rhombus picture mosaic is that the same length of side and identical thickness are arranged, and drift angle is π/n(n=3,4 ...) the rhombus flat board of integral multiple.They are placed on the smooth basal plane, or in flat assorted cold dishes, amalgamation mutually in a variety of forms, variation and color combinations by position between jigsaw form various figures.

N among above-mentioned π/n, be one more than or equal to 3 integer.For each value of n, just corresponding have a kind of rhombus jigsaw puzzle, and Integer n is called " denominator " of this a kind of rhombus jigsaw puzzle.Denominator is the rhombus jigsaw puzzle of n, and when n was even number, the shape of its basic jigsaw had the n/2 kind, and they are that drift angle is respectively π/n, 2 π/n ..., the rhombus of pi/2; When n is odd number, total (n-1)/2 of the shape of its basic jigsaw kind, they are that drift angle is respectively π/n, 2 π/n ... (n-1) rhombus of pi/2 n.

In a cover rhombus jigsaw puzzle, the piece number of various rhombus jigsaw is unqualified, and in general, the piece number is many more, and the composition ability of this cover rhombus jigsaw puzzle is strong more.According to my research, make a cover rhombus jigsaw puzzle have maximum spellings and change, then when denominator n was odd number, drift angle was π/n, 2 π/n ..., (n-1) the piece number of the various rhombus jigsaw of pi/2 n should equate; When n was even number, drift angle was π/n, 2 π/n ..., (n-1)/the piece number of the various rhombus jigsaw of 2n, all should be 2 times of square jigsaw piece number.

So-called assorted cold dishes are that the degree of depth of a sunk part equates or close flat chassis with jigsaw thickness, and the shape of sunk part is the shape that the rhombus jigsaw can be risked.The shape of assorted cold dishes depression should be able to make jigsaw that full this depression of different ways assembly is perhaps arranged.For denominator is the rhombus jigsaw puzzle of n, can guarantee the assorted cold dishes that jigsaw has maximum spellings to change in assorted cold dishes, the shape of its depression, should be a length of side be the rhombus jigsaw length of side m doubly (m=1,2 ...) positive 2n limit shape.

Below be example with n=7, and in conjunction with the accompanying drawings, the utility model will be further described.

Fig. 1, Fig. 2, the shape of the basic jigsaw of the utility model (1), (2), (3) when Fig. 3 is n=7, their drift angle is respectively π/7,2 π/7,3 π/7.

The utility model jigsaw figure that amalgamation goes out on the basal plane of plane when Fig. 4 is n=7.

The front view of a kind of positive 14 limit shape assorted cold dishes of the present utility model when Fig. 5 is n=7, part has been made section among the figure, with frame (4) and the assorted cold dishes depressions (5) that show projection.

The vertical view of a kind of positive 14 limit shape assorted cold dishes of the present utility model when Fig. 6 is n=7, the shape of demonstration assorted cold dishes depressions (5).

The jigsaw of the present utility model figure that amalgamation goes out in positive 14 limit shape assorted cold dishes when Fig. 7 is n=7.

The said basic jigsaw of the utility model can be made by the timber or the plastics of different colours.

Jigsaw is amalgamation on basal plane, is meant jigsaw is shakeout on basal plane one by one, is not superimposed between the jigsaw, and to fit mutually on the limit, by the different permutation and combination of jigsaw mutual alignment and color, risks various figures.Jigsaw is amalgamation in assorted cold dishes, should piece together full depression and not interspace.

The utility model has following beneficial effect:

1, spelling changes various.In assorted cold dishes, the spelling that same some jigsaw are pieced together full these assorted cold dishes is countless, adds the jigsaw change in color again, and more it is various for the figure of institute's energy amalgamation.Break away from the restriction amalgamation in the plane of assorted cold dishes, change more.

2, the figure of risking can extremely approach with common things.

3, the amalgamation of jigsaw will be followed certain rule, the intelligence of therefore can exercising by this.

Claims

1, a class rhombus jigsaw puzzle comprises many kinds of rhombus jigsaw puzzles, it is characterized in that, the basic jigsaw of each rhombus jigsaw puzzle is the identical flat board of thickness, and shape is that drift angle is π/n (n=3,4,) integral multiple, and various rhombuses that the length of side is equal to each other.

According to the rhombus jigsaw puzzle of claim 1 defined, it is characterized in that 2, when n was even number, the basic jigsaw kind number of this rhombus jigsaw puzzle had the n/2 kind, when n was odd number, the basic jigsaw kind number of this rhombus jigsaw puzzle had (n-1)/2 kind.
