A kind of three-layer stereo jigsaw
Technical field
The utility model relates to teaching aid or toy, particularly a kind ofly belongs to a kind of three-layer stereo jigsaw that space multistory piece together to be played type, 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 space thinking in images of training of students, excite the potential innovation ability of people.
Background technology
Technology content is on the low side in the present like product, and particularly the people in modern living standard improves, and need on higher knowledge aspect, carry out amusement; For adapting to this variation, said a kind of three-layer stereo jigsaw can address this problem, and seems simple; Piece together good and be not easy; Have only through making great efforts and having certain topological geometric knowledge, just can be combined into assignment graph, reach the purpose of training thinking simultaneously.
Summary of the invention
In order to solve the apparatus problem that people use one's hands and brains, the utility model provides a kind of three-layer stereo jigsaw according to topological geometric knowledge, pieces together the player and should consider that the upper strata takes middle lower floor again into account; Can make people through using one's hands and brains; Cultivate thinking in images, the training memory capability improves intellectual level.
The scheme that the utility model adopted is:
A kind of three-layer stereo jigsaw is made up of as base unit and assorted cold dishes six jigsaw; Said six jigsaw are formed by lower floor's jigsaw, middle level jigsaw and upper strata jigsaw; Said lower floor jigsaw, middle level jigsaw and upper strata jigsaw are isosceles trapezoid; Said isosceles trapezoid is that the equilateral triangle of 1 centimetre of 3 length of side, 0.5 centimetre of thickness is overlapped contiguously the side and is joined together to form in the side in the plane; Said isosceles trapezoid is made up of a upper base equilateral triangle and two equilateral triangles of going to the bottom; Proper one of them said equilateral triangle of going to the bottom of two said isosceles trapezoids is overlapped face-to-face the two-layer jigsaw that is connected to form a kind of combination contiguously, proper one of them said equilateral triangle of going to the bottom of a more said isosceles trapezoid is overlapped face-to-face contiguously and be connected on the said two-layer jigsaw and be formed with and only six jigsaw said six base units that jigsaw is said a kind of three-layer stereo jigsaw; Said assorted cold dishes are regular hexagon, and the length of side of said assorted cold dishes is integral multiples of 1 centimetre.
When taking 12 said base units, can be combined into the said assorted cold dishes of 6 centimetres of the length of sides; When taking 27 said base units, can be combined into the said assorted cold dishes of 9 centimetres of the length of sides; When taking 48 said base units, can be combined into the said assorted cold dishes of 12 centimetres of the length of sides.Piece together the player and should consider that the upper strata takes middle lower floor again into account, need certain topological geometric knowledge, bigger to primary grades child difficulty.Described: just one of them said equilateral triangle of going to the bottom overlaps contiguously face-to-face and connects, and keyword is whole rather than two or an arbitrarily connection, and what stress again is said equilateral triangle rather than the said upper base equilateral triangle of going to the bottom.According to said six objects that jigsaw is the utility model patent protection that said connected mode obtains, its structure has certainty, shape has uniqueness, and promptly said six jigsaw are two neither coincidences in the space.
The beneficial effect of the utility model is:
As if said a kind of three-layer stereo jigsaw simple structure cost is low, sees containing profundity among simple, pieces together the player and needs certain topological geometric knowledge, after turning round and look at again before should looking forward or upwards, through the cultivation thinking in images that uses one's hands and brains.
Description of drawings
Figure below in conjunction with the utility model further specifies:
Fig. 1 is said equilateral triangle plane;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is said isosceles trapezoid plane;
Fig. 4 is said two-layer jigsaw plane;
Fig. 5 to Figure 10 is said six jigsaw planes;
Figure 11 is an example of said assorted cold dishes.
Among the figure, 1. upper base equilateral triangle, the equilateral triangle of 2. going to the bottom, 3. lower floor's jigsaw, 4. middle level jigsaw, 5. upper strata jigsaw.
The specific embodiment
Like Fig. 1 is said equilateral triangle plane, is the vertical view of Fig. 2, and the said equilateral triangle length of side is 1 centimetre.
Like Fig. 2 is the upward view of Fig. 1, reflects said equilateral triangle side, and said equilateral triangle thickness is 0.5 centimetre.
Like Fig. 3 is said isosceles trapezoid plane, and said isosceles trapezoid is made up of a upper base equilateral triangle (1) and two equilateral triangles of going to the bottom (2).
Like Fig. 4 is said two-layer jigsaw plane, is the face-to-face a kind of combination that overlaps connection contiguously and form of proper one of them said equilateral triangle of going to the bottom with two said isosceles trapezoids (like Fig. 3), by lower floor's jigsaw (3) and middle level jigsaw (4) formation.
Like Fig. 5 to Figure 10 is said six jigsaw planes; Be that proper one of them said equilateral triangle of going to the bottom with a said isosceles trapezoid overlaps contiguously face-to-face and is connected on the said two-layer jigsaw (like Fig. 4) and is formed with and only said six jigsaw; Form said six base units that jigsaw is said a kind of three-layer stereo jigsaw by lower floor's jigsaw (3), middle level jigsaw (4) with upper strata jigsaw (5).
Described: just one of them said equilateral triangle of going to the bottom overlaps contiguously face-to-face and connects, and keyword is whole rather than two or an arbitrarily connection, and what stress again is said equilateral triangle rather than the said upper base equilateral triangle of going to the bottom.According to said six objects that jigsaw is the utility model patent protection that said connected mode obtains, its structure has certainty, shape has uniqueness, and promptly said six jigsaw are two neither coincidences in the space.
Narrating said six jigsaw again obtains like this: earlier the equilateral triangle (like Fig. 1) of 1 centimetre of 3 length of side, 0.5 centimetre of thickness is overlapped contiguously the side and is joined together to form isosceles trapezoid (like Fig. 3) in the side in the plane; Said isosceles trapezoid is made up of a upper base equilateral triangle (1) and two equilateral triangles of going to the bottom (2); Proper one of them said equilateral triangle of going to the bottom (2) of two said isosceles trapezoids is overlapped the two-layer jigsaw (like Fig. 4) that is connected to form a kind of combination face-to-face contiguously; Said two-layer jigsaw is made up of lower floor's jigsaw (3) and middle level jigsaw (4), proper one of them said equilateral triangle of going to the bottom of a more said isosceles trapezoid is overlapped face-to-face contiguously to be connected on the said two-layer jigsaw and to be formed with and only six jigsaw.
Like Figure 11 is an example of said assorted cold dishes; Said assorted cold dishes are regular hexagon, and the length of side of said assorted cold dishes is integral multiples of 1 centimetre, are that the length of side is 6 centimetres a said assorted cold dishes plane among the figure; Adopt 12 said base units can be combined into one as figure to have a regular hexagon of three layers three-dimensional; Piece together the player and should consider that the upper strata takes middle lower floor simultaneously again into account, need certain topological geometric knowledge, through the cultivation thinking in images that uses one's hands and brains.
