Description

Seven-piece puzzle

The utility model has related to a kind of seven-piece puzzle, and it belongs to puzzle.

Through patent retrieval, the patent No. is the box-like plate of beggingging for cleverness of CN2045659U, and plate is 21, can risk the most of Chinese character and the Latin alphabet and various things figure.But this toy has following shortcoming: 1, plate is too many, and is too numerous and diverse, and the player is difficult for holding.2, be not suitable for developing the intelligence of youngsters and children with it.3, only lift several picture mosaic examples, do not provided the concrete pattern that to compose and lay out, can not satisfy player's needs far away.4, plate is too many, is difficult for being developed to product.

In order to overcome the shortcoming of original technology, the purpose of this utility model is to utilize seven-piece puzzle to design the piece pattern of the elementary, middle and high retaining of a cover.Comprising profile diagram (exercise question) and structure chart (answer).The plate of various colours made of plastic, and supporting profile diagram and structure chart are contained in the box, produce both artistic and practical seven-piece puzzle jack-in-a-box.

The purpose of this utility model realizes by following concrete measure.

A kind of seven-piece puzzle is characterized in that being made up of two big triangles, two little triangles, an intermediate cam shape, a square and a parallelogram.Comprising three kinds of areas, three kinds of angles and four kinds of length of sides.By the permutation and combination of their different modes, 1022 different patterns have been risked.According to the complexity of assembly group, form elementary, middle and high three ranks by two boards, three blocks of plates, four blocks of plates, five blocks of plates, six blocks of plates, seven blocks of plates.Elementary group 338,328 of middle rank groups, senior group 377.844 symmetric figures are wherein arranged.In 1022 patterns, design profile diagram (exercise question) and structure chart (answer) two covers.

The area of these plates has three kinds, and wherein the area of square, parallelogram and intermediate cam shape all equates, and equals 2 times of little triangle area, also equals 1/2nd of big triangle area.These plates have three kinds of angles, i.e. 45 degree, 90 degree and 135 degree.Plate has four kinds of length of sides: 1, the length of side of the length of side of parallelogram minor face, little triangle right-angle side and the foursquare length of side all equate, establishing its length is a.2, the length of side, the length of side of little triangle hypotenuse and the length of side of intermediate cam shape right-angle side on the long limit of parallelogram all equate, all equal $\sqrt{2}a$ 。3, the length of side of the length of side of intermediate cam shape hypotenuse and big triangle right-angle side equates, equals 2a.4, the length of side of big triangle hypotenuse equals $2\sqrt{2}a$ 。

The utility model has the advantages that: 1, plate is few, and the player holds easily, is convenient to popularize.2, be suitable for face width.Very suitablely be used for developing children and teen-age intelligence, suitable again adult and the elderly use.3, the picture mosaic example is many.1022 patterns, image is concrete lively, and as kitten, the big tree of Figure 35 picture etc. can excavate fully that the player thinks independently, the ability of creative thinking, in addition with answer, are convenient to cross-checked as Figure 22.4, plate is developed to product less easily, can obtain bigger society and economic benefit.

Accompanying drawings is as follows:

Fig. 1 is that the seven-piece puzzle plate is manufactured figure.

Fig. 2, Fig. 3, Fig. 4, Fig. 5 are the profile diagram and the structure charts of two boards assembly group.

Fig. 6, Fig. 7, Figure 10, Figure 11 are the profile diagram and the structure charts of three plate assembly groups.

Fig. 8, Fig. 9, Figure 12, Figure 13 are the profile diagram and the structure charts of four plate assembly groups.

Figure 14, Figure 15, Figure 18, Figure 19 are the profile diagram and the structure charts of five plate assembly groups.

Figure 22-Figure 49 is the profile diagram and the structure chart of seven plate assembly groups.

See Fig. 1, ABCD is a square, and E is the mid point of AB, and F is the mid point of BC, and G is the mid point of EF, EH  AC, GL ∥ BC.By each line divide cut the back seven-piece puzzle.

Claims (1)

1. seven-piece puzzle, it is characterized in that by two big gores (1), (7), two little gores (3) (6), an intermediate cam shape piece (5), a square block (4) and a parallelogram piece (2) are formed an ABCD square block, and E is the mid point of AB, F is the mid point of BC, G is the mid point of EF, EH  AC, GL ∥ BC.
