Abstract

The utility model relates to a teaching aid or a toy, in particular to a three-layer rectangular jointed boards which are formed by six jointed boards used as basic units and a jointed plate, wherein the six jointed boards are respectively formed by a lower layer rectangle, a middle layer rectangle and an upper layer rectangle; each rectangle is formed by two squares with one centimeter of side length and half a centimeter of thickness, and the two squares are overlapped and connected in a mode that a side face of one square corresponds to a side face the other square on one plane. Two-layer joint boards are formed by two rectangles which are perpendicularly arranged in a mode that a whole square of one rectangle and a whole square of the other rectangle are overlapped and connected in face-to-face mode, and then the only six jointed boards are formed by means of further arrangement of another rectangle in a mode that a whole square of the rectangle is overlapped and connected on the two-layer joint board face-to-faces in a contacting mode. The jointed plate is in a rectangle shape, and side length of the jointed plate is integral multiple of one centimeter. The three-layer rectangular jointed boards are simple in structure and low in cost, players need to know certain knowledge about topology and geometry so as to cultivate thinking in images by manual work and using of brain.

Description

A kind of three layers of rectangle jigsaw

Technical field

The utility model relates to teaching aid or toy, particularly a kind ofly belongs to a kind of three layers of rectangle 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 layers of rectangle jigsaw can address this problem, and seem 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 layers of rectangle 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 layers of rectangle jigsaw are made up of as base unit and assorted cold dishes six jigsaw; Said six jigsaw are formed by lower floor's rectangle, middle level rectangle and upper strata rectangle; Said six jigsaw obtain like this: earlier the square of 1 centimetre of 2 length of side, 0.5 centimetre of thickness is overlapped contiguously the side and is joined together to form rectangle in the side in the plane; With 2 said rectangles vertically just one of them said facing opposite overlap contiguously and be connected to form two-layer jigsaw; Said two-layer jigsaw is made up of lower floor's rectangle and middle level rectangle; Proper one of them said facing opposite of a said rectangle is overlapped contiguously again and be connected on the said two-layer jigsaw and be formed with and only six jigsaw, said assorted cold dishes are rectangle, and the length of side of said assorted cold dishes is 1 centimetre a integral multiple.Described: just one of them said facing opposite overlaps connection contiguously, and emphasical is lucky one whole rather than random connection.Said six base units that jigsaw is said a kind of three layers of rectangle jigsaw adopt 2 said base units can be combined into 3 * 8 square centimeters rectangle; Adopt 4 said base units can be combined into 6 * 8 square centimeters rectangle; Adopt 6 said base units can be combined into 8 * 9 square centimeters rectangle; Adopt 48 said base units can be combined into 24 * 24 square centimeters rectangle; Or the like; Piece together the player and should consider that the upper strata takes middle lower floor again into account, need certain topological geometric knowledge, different crowd can be selected the said assorted cold dishes of different area.

The beneficial effect of the utility model is:

As if said a kind of three layers of rectangle jigsaw simple structure cost are low, see containing profundity among simple.Also can select the said assorted cold dishes of different area according to different crowd, piece together the player and need certain topological geometric knowledge, the training memory capability is cultivated thinking in images.

Description of drawings

Figure below in conjunction with the utility model further specifies:

Fig. 1 is said square-shaped planar figure;

Fig. 2 is said square upward view;

Fig. 3 is said rectangle plane figure;

Fig. 4 is said two-layer jigsaw plane;

Fig. 5 is the upward view of Fig. 6;

Fig. 6 to Figure 11 is said six jigsaw planes;

Figure 12 is an example of said assorted cold dishes.

Among the figure, 1. lower floor's rectangle, 2. middle level rectangle, 3. upper strata rectangle.

The specific embodiment

Like Fig. 1 is said square-shaped planar figure, is the vertical view of Fig. 2,1 centimetre of the said square length of side.

Like Fig. 2 is said square upward view, reflects said square sides, 0.5 centimetre of said square thickness.

Like Fig. 3 is said rectangle plane figure, is 2 said squares are overlapped the rectangle that is joined together to form in the side in the plane contiguously to the side.

Like Fig. 4 is said two-layer jigsaw plane, vertically proper one of them the said facing opposite of 2 said rectangles (like Fig. 3) is overlapped contiguously be connected to form, and is made up of lower floor's rectangle (1) and middle level rectangle (2).

Like Fig. 5 is the upward view of Fig. 6, reflects three layers position relation.

Like Fig. 6 to Figure 11 is said six jigsaw planes; Be that proper one of them said facing opposite with a said rectangle overlaps contiguously and is connected in having and only six jigsaw of forming on the said two-layer jigsaw (like Fig. 4), said six jigsaw are formed with upper strata rectangle (3) by lower floor's rectangle (1), middle level rectangle (2).Described: just one of them said facing opposite overlaps connection contiguously, and emphasical is lucky one whole rather than random connection.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.

Like Figure 12 is an example of said assorted cold dishes; Said assorted cold dishes are rectangle, and the length of side of said assorted cold dishes is 1 centimetre a integral multiple, are one 3 * 8 square centimeters rectangle plane figure among the figure; Adopting 2 said base units can be combined into 3 * 8 square centimeters rectangle, is a solid with three layers after being combined into.Piece together the player and should consider that the upper strata takes middle lower floor again into account, can select the said assorted cold dishes and the corresponding said base unit of different area according to different crowd.

Claims (1)

1. three layers of rectangle jigsaw; It is characterized in that: said a kind of three layers of rectangle jigsaw are made up of as base unit and assorted cold dishes six jigsaw; Said six jigsaw are formed with upper strata rectangle (3) by lower floor's rectangle (1), middle level rectangle (2); Said rectangle is that the square of 1 centimetre of 2 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; With 2 said rectangles vertically just one of them said facing opposite overlap contiguously and be connected to form two-layer jigsaw; Proper one of them said facing opposite of a said rectangle is overlapped contiguously again and be connected on the said two-layer jigsaw and be formed with and only six jigsaw, said assorted cold dishes are rectangle, and the length of side of said assorted cold dishes is 1 centimetre a integral multiple.
