Abstract

The utility model discloses a polygonal building lock member. Each member has a unified edge length, and each edge of each member is provided with a locating surface (1) and hinges, wherein, the positioning surface (1) is positioned on the midpoint of the edge length, and the hinges which can hinged with each other are composed of elastic positioning pins (2) and positioning holes (3). The utility model not only can joint a conventional rule shape, but also can joint integrally irregular shapes and various ball shapes in a bending and stretching mode in space. The utility model can be used for manufacturing building block type toys, household displaying articles, teaching aids, various simple mobile buildings which can be disassembled and jointed conveniently, advertising mediums, urban decorative articles, etc.

Description

A kind of Block structural unit

The utility model is a kind of cordwood structural design.

The utility model is made up of one group of polygonal plane Block structural unit, on every limit of member all by the be hinged hinge of usefulness of the confession of forming by locating surface and elastic positioning pin and locating hole.In the market only by inlay the similar toy product that the square of location and triangle building blocks are formed by wide tooth limit.Because the shape kind of member is few, splicing relation each other is single, simultaneously, lacks the accurate localization means, so, limited the spatial modelling ability of product widely.In addition, this technology as when constructing mobile structure, also can't be applied in practical field.

The purpose of this utility model is by the accurate localization means are provided, realize splicing relation complicated between the various members, thereby opened up the spatial modelling ability of product greatly, except making the building block system toy, outside household arrangement and the teaching aid, after the exaggerated scale, also can be used for making the simple and easy mobile structure of various uses, advertising carrier and urban decoration etc.

On every limit of member, locating surface that is positioned at length of side mid point and elastic positioning pin and the locating hole that supplies hinged usefulness are all arranged, in the one side that guarantees member is under the prerequisite of outside, any both sides of any two members all can offset by both locating surfaces to make and piece together both sides mutually and accurately align, and realize hinged by separately elastic positioning pin and the other side's locating hole again.After hinged, these two members will be all the time in two elastic positioning pins under the acting in conjunction of two springs, common centreline along elastic positioning pin and locating hole pushes against on locating surface mutually, simultaneously, can also be axle with the common centreline of elastic positioning pin and locating hole each other, do swing relatively.Because all members all have the adjacent side of the equal length of side and every kind of member various angle are all arranged, therefore, as in the moulding that the part assembly is put up, when having the angle of two or more free margins just in time to equate in proper order with the angle of the adjacent side of a certain member, can with this member convenient piece together go into exactly to this part piece together in the moulding of having put up.In addition, also can piece together to go into to a main moulding with piecing together good sub-shape integral ground in advance.Final moulding can be opened wide, and also can seal.

The utility model has abundanter spatial modelling ability compared with prior art, can risk various ball with it, and casper can be at the irregular moulding and the various temporary building of space bending stretching, extension.Because the utility model has adopted locating surface location and elastic positioning pin and the hinged structure of locating hole, so fast assembling and disassembling, the location is reliable, and moulding is accurate, has greatly satisfied the needs of user's frequent changes moulding, has improved the service efficiency of product.

Fig. 6 is a kind of moulding that utilizes the utility model to construct.

Now in conjunction with the accompanying drawings to realizing that a kind of mode of the present utility model is described in further detail.In the present embodiment, earlier do base with hexagon member shown in Figure 1, assert that the hollow out face is the outside, the locating surface (1) on arbitrary limit of quadrangle member shown in Figure 2 is alignd with the locating surface (1) on arbitrary limit of hexagon member, make two members mutually hinged by means of elastic positioning pin (2) and locating hole (3), after hinged, under the acting in conjunction of two springs in two elastic positioning pins (2), two members push against mutually on locating surface (1) automatically.Common centreline with elastic positioning pin (2) and locating hole (3) is an axle, the quadrangle member is started, when the angle of these two adjacent two free margins of member by chance equals the angle of pentagon member two adjacent sides shown in Figure 3, with this pentagon member piece together into.Then, all the other four limits of hexagon member are pieced together in turn into quadrangle member and pentagon member, after end face is pieced together triangle member shown in Figure 4 and another kind of quadrangle member shown in Figure 5 in turn, just risked the moulding shown in Fig. 6 again.At last, can on remaining as shown in the figure free margins, continue moulding or directly bind.When the size of member is enough big, and after being used in combination certain seal, construct various simple and easy mobile structures, advertising carrier and urban decoration etc. with regard to available its.

Claims

1. Block structural unit, it is made up of one group of polygonal member, it is characterized in that various polygonal member all have the unified length of side, all have on every limit of every kind of member by the locating surface (1) that is positioned on the length of side mid point, elastic positioning pin (2) and locating hole (3) form for mutually hinged hinge.

2. according to right 1 described Block structural unit, when it is characterized in that amalgamation, the elastic positioning pin of a member (2) acts on the locating hole (3) of another member of piecing together mutually with it on the hinged limit, and these two members are adjacent on locating surface (1) mutually along the common centreline of elastic positioning pin (2) and locating hole (3).
