Description

The spheroid piece

Technical field

The utility model relates to education and instruction apparatus or toy, in teaching during geometric knowledge, the teacher is gained knowledge having a kind of effective instrument to make the student use institute after school, and use one's hands and brains.Through the memory capability of training of students, cultivate thinking in images, excite the potential innovation ability of people.

Background technology

Technology content is on the low side in the present like product, and they mainly are fit to the crowd below child and the middle school, and knowledge and technology content are higher and to be fit to the like products that great majority are grown up less; Particularly the people in modern living standard improves; Need be in the enterprising capable amusement of higher knowledge aspect, for adapting to this variation, the spheroid piece can address this problem; Provide a kind of student of making can use the geometric knowledge of learning, the object for appreciation apparatus is pieced together in the space of active again manually brain.

Summary of the invention

As everyone knows, the football surface can be the sphere that equal regular pentagon of the length of side and regular hexagon edge-to-edge are combined to form contiguously, and yes has dashed the sphere that forms after the gas.In order to solve the apparatus problem that people use one's hands and brains; The utility model can be that 12 regular pentagons and 20 regular hexagons that the length of side equates are formed according to the football surface; A kind of spheroid piece is provided, people are used one's hands and brains, the training memory capability; Cultivate thinking in images, make the brain balanced growth of the people left and right sides to improve intellectual level.

The scheme that the utility model adopted is:

The spheroid piece is made up of six kinds of pieces; First kind of piece is that the bottom surface length of side is 1 unit and incline length is the positive pentagonal pyramid of 2.4 units; Second kind of piece is that the bottom surface length of side is 1 unit and incline length is the positive hexagonal pyramid of 2.4 units; The third piece is by said positive pentagonal pyramid and said positive hexagonal pyramid side the side to be combined contiguously and formed; The 4th kind of piece is by said positive pentagonal pyramid and two said positive hexagonal pyramid sides the side to be combined contiguously and formed, and said the 4th kind of piece has two types, and the 5th kind of piece is by said positive pentagonal pyramid and three said positive hexagonal pyramid sides the side to be combined contiguously and formed; Said the 5th kind of piece has two types, and the 6th kind of piece is by said positive pentagonal pyramid and four said positive hexagonal pyramid sides the side to be combined contiguously and formed.

According to the spheroid relevant knowledge; Spherome surface can be that 12 regular pentagons and 20 regular hexagons that the length of side equates are formed; Promptly this spheroid can be made up of 12 positive pentagonal pyramids and 20 positive hexagonal pyramids, and the incline appearance of said positive pentagonal pyramid and positive hexagonal pyramid etc. also are the radiuses of this spheroid.Through calculating, when the said positive pentagonal pyramid and the said positive hexagonal pyramid bottom surface length of side were 1 unit, it was 2.469 units that its incline is about, the utility model get 2.4 units be for when piecing together object for appreciation, can piece together easily into.

Spherome surface has certain rule when being made up contiguously by 12 regular pentagons and 20 regular hexagon edge-to-edges, this is the basis of said six kinds of pieces design, also leaves people for and goes to observe and use one's hands and brains.

The beneficial effect of the utility model is:

Said spheroid piece is reasonable in design, can make the student utilize institute to gain knowledge and use one's hands and brains and observe life, and the different thought mode forms multiple different following the example of and spelling, piece together play interesting.

Fig. 8 is the spheroid schematic appearance that is combined into.

Among the figure, 1. base, 2. incline, 3. side.

Embodiment

Like Fig. 1 is said positive pentagonal pyramid synoptic diagram, and orthopyramid is meant that the bottom surface is a regular polygon, and each side all is the isosceles triangle that equates, said positive hexagonal pyramid is also like this.Said positive hexagonal pyramid and said positive pentagonal pyramid all are that the bottom surface length of side is 1 unit and incline length is 2.4 units, so their each side all is the isosceles triangle that equates, can the side be combined by side contiguously.The positive pentagonal pyramid of said Fig. 1 is said first kind of piece, and said positive hexagonal pyramid is said second kind of piece.

Like Fig. 2 is the stretch-out view of two bottom surfaces when by said positive pentagonal pyramid and said positive hexagonal pyramid side the side being combined contiguously.Said Fig. 2 is said the third piece.

Like Fig. 3, like the stretch-out view that Fig. 4 is three bottom surfaces when by said positive pentagonal pyramid and two said positive hexagonal pyramid sides the side being combined contiguously, two types of different combinations are arranged obviously.Said Fig. 3, Fig. 4 are said the 4th kind of piece.

Like Fig. 5, like the stretch-out view that Fig. 6 is four bottom surfaces when by said positive pentagonal pyramid and three said positive hexagonal pyramid sides the side being combined contiguously, two types of different combinations are arranged also.Said Fig. 5, Fig. 6 are said the 5th kind of piece.

Like Fig. 7 is the stretch-out view of five bottom surfaces when by said positive pentagonal pyramid and four said positive hexagonal pyramid sides the side being combined contiguously.Said Fig. 7 is said the 6th kind of piece.

Like Fig. 8 is the said spheroid schematic appearance that is combined into, and the easiest a kind of embodiment of being combined into is: get 12 of said first kind of pieces, get 20 of said second kind of pieces, be combined into said spheroid.Other are left people than difficult following the example of for spelling and start.
