Abstract

A magnetic building block playing system has magnetic building blocks for building miniature models of imaginary or historic buildings and settlements. The basic element of the system is a magnetic building block with the following characteristics: (a) it has a cuboid shape quarter of brick size; (b) its base material is an ordinary plastic material (for example ABS) and its magnetic material is a magnetisable thermoplastic material; (c) its magnetic coupling points are shaped as squares or circles with axially symmetrical, overlapping inner and outer surfaces; and (d) it is magnetised so that the inner and outer surfaces of the coupling points are unlike, so that the coupling points of two surfaces to be coupled are oppositely poled.

Description

Magnetic building block playing system

The present invention relates to a kind of building puzzle of forming with the magnetic building blocks element, be mainly used in toy, also can make teaching aid and/or be used to illustrate the design of building category and can collude and make careless sample.

Based on magnetic force, the single building block of building blocks links together easily mutually, and can be under big reverse external force effect and separate, and these class building blocks are a kind of simple, the conventional toy that applicability is strong in the building category, have higher moral, and can bring a lot of enjoyment.

Existing magnetic playset is fixed on the carrier (as wood or plastics) with permanent magnet and/or magnetic paper tinsel and/or splint (as separated portions) and makes.Here permanent magnet generally is that axial magnetized is crossed (perhaps also using the ferromagnetic circuit sheet), and the magnetic paper tinsel generally is that one side is carried out the strip magnetization, makes north and south poles be strip and alternately changes (referring to Fig. 4).

The building block of existing magnetic building blocks and the block toy of existing mechanical (for example LEGO, Fischer technology) are compared, and the flexibility of its connection is very limited.The shape of this and its (a) building block, (b) magnetic material of Shi Yonging, (c) quantity of the effective tie point of magnetic, geometry and arrangement and (d) magnetization technology of tie point is relevant.Thus, they especially are not suitable for house, building and machine, plant, animal and human's class etc. truly dwindle moulding.Existing magnetic building blocks form is single-orientated, thereby the shape required to the actual building of moulding multiaspect (for example DIN-physical dimension standard) has been very little.

Permanent magnet is imperfect (referring to relevant P4306573.2 and G9304198.5 patent of invention file) with the magnetic paper tinsel at aspects such as its weight, geometry, manufacturing and mechanical strain or thermal strains.

In addition, the existing building block of making of permanent magnet generally has only a magnetic tie point on a contact surface.Because most surfaces is connected by magnetic, therefore almost be difficult to they displacements.

For the magnetic that reaches entire contact surface connects, generally adopt the magnetized metal forming of strip (referring to Fig. 4), so just can constitute " dislocation " building, but still not have vertical-horizontal connection of building block.

Connect the magnetization that variation depends primarily on geometric modelling and tie point (and joint face).

As adopting the following new magnetization technology of described tie point of the present invention, adopt the former axial or magnetized building block of strip, the possible mode of its connection seems still less.

A kind of building toy building blocks in patent DE2704204A1, have been introduced, in order to building construction.It is the building block of a kind of net grating system insertion capable of being combined.Here related is a kind of insertion system that does not have magnet.When having adopted magnetic force as connection power in front in the patent, as LEGO, DUPLO and Fischer technology, pure mechanical force is still adopted in its connection, provides another type (or partly) building puzzle and recreation building blocks thus.

Described a kind of magnetic building block playing system in patent DE-GM8023609, it " has a permanent magnet " at least, promptly on the surface of the plastics building blocks block (partly or entirely) of these class building blocks, is equipped with permanent magnet or magnetizable element.The arrangement feature of permanent magnetism is that they have the end scope that " end cap " inserts block, and can find out in the drawings.

There is not statement there about the axial symmetry arrangement of permanent magnet or about magnetized situation.And relevant magnetic tie point on parent (n * m) arranges (n, m is the number greater than 1) here, does not only have literal but also do not have figure to be illustrated, and this is crucial to " dislocation is constructed ".

In patent DE-OS1942333, describe a kind of " building blocks that are used for BUILDINGS MODELS ", be characterized in " in the plastic body of building block, imbedding a permanent magnet at least ".Here, " permanent magnet can be the fine particle that distributes in stock, same then direction magnetization ".

DE-GM8023609 is similar to patent, and the axially-aligned situation of permanent magnet is not described, or exactly, the magnetized accurate process of permanent magnet is not described.It is very little to go to construct " dislocation building " possibility that shape determines with building blocks described herein.

Analogue also has, and the absorption magnet system non-toy of being chatted in patent DE-GM1737900 and DE-GM1783302, industrial has adopted interior ring and outer shroud Magnitizing method.

Some difference is arranged certainly, and promptly overlap in the polar region in the DE-GM173790 patent, and in DE-GM1783302, r do not occur ₂＞r ₁Situation.

In patent US-PS3196579, show magnetic building blocks, they are made up of four parts: 1) rectangular six plastic bodies of center sky, and there is cell structure (4 * 2) its underpart, is standard-sized sheet above, 2) iron plate that 4 * 2 grids are housed, mechanical mating reaction is played in the bottom of it and building block; 3) little magnetic sheet, it is placed in the plastic grill of bottom, 4) thin splint, it is installed in the reverse edge of little magnetic sheet.

Because the magnetic building blocks piece has 4 * 2 cell structures that machinery cooperates, connect so can constitute dislocation on request.

The essential distinction of the present invention and patent US-PS3196579 is: latter's magnetic material is the top that is evenly distributed on long-pending piece-base, by the mechanical grille on iron plate and plastic body-base, thereby obtains the structure of 4 * 2 matrix.Be not aided with mechanical fixation if having, then just can not obtain the dislocation building of suitable shape.In contrast, among the present invention, magnetic material itself has been arranged in 4 * 2 matrix structures (concentric), thereby need not the mechanical fixed device, but building block just can be by means of magnetic force moulding and mutual dislocation.

Further difference is: magnet is adsorbed on the metal earlier in US-PS3196579, and the present invention is that magnet is directly to magnet.In addition, its magnetized pole arrangement is also inequality.

The task that the present invention solves is: get rid of existing shortcoming in the aforementioned patent, use simple method to construct to dwindle imaginative or real building as far as possible.

These targets are to realize by the method that claim 1 is indicated

In order to be fit to the aesthstic requirement and the sense of reality, suitable cooperation is important, for example the spot sandstone look building block of your ground wine and women-sensual pursuits of usage.

When moulding, adopt the ratio of reliable DIN building scale.Basic building block is selected rectangular parallelepiped for use, and the ratio L of its length and width height: B: H is 3: 1.5: 1.

By demultiplication and/or extraordinarily, be easy to obtain other building block (Fig. 2).Be used for moulding front, house such as window, door, roof and different-style (as classic, Rome type and hebephrenictype).With regard to material, on the one hand base material and packing material are arranged, also adopt different magnetic materials on the other hand.

Common plastics (for example coloured) can be used as base-material, and magnetic material recommend to adopt magnetic/magnetizable composite material, and it is by a) plastics; B) magnetic and magnetisable material c) may also have some additives (pigment) to form.

A kind of example: so-called " magnetizable thermoplastic " is commonly referred to " plastics magnetic material " or " plastic magnet ".

As what in the G9304198.5 patent, described, the plastics magnetic material be arranged with multiple possibility.Compare with common magnetic material, adopt the plastics magnetic material, people can more freely mould image.The mechanical stability and the heat endurance of this moulding for the magnetic tie point, building block are vital.Accomplish the variation of tie point, at first importantly the quantity of magnetic tie point is arranged and geometry.For can realize vertically/vertically and vertically/horizontal being connected, recommendation is with axial symmetry and rotational symmetric tie point, as square or circumferential plane.For mould " dislocation " and configuration clocklike, on the surface of building block, need a lot of equally distributed, axisymmetric tie points (Fig. 3 and Fig. 5).

The quantity of tie point is many more, can constitute " tiny dislocation " more, and magnetization technology is important here certainly.

Because homopolar-repulsion, heteropole are inhaled (the N-arctic, the S-South Pole) mutually, the N-S of the institute utmost point distributes and can not select arbitrarily.Illustrated among Fig. 6 by the arrangement most probably of Fig. 5 tie point North-south.Here as can be seen, adopt this magnetization technology, the variation of tie point is more much more than the magnetic playset known to so far, particularly can accomplish to connect in length and breadth.

When moulding, must note the correct upset of building block always, be also noted that tie point can only (repeat) respectively to connect with next point range again, because a bit repelling each other with it of being right after.

Otherwise, desirable building block, all tie points on the building blocks face of two needs connections attract each other, and so just need not to have considered the arctic and the South Pole when moulding.Fig. 1 illustrates a kind of solution, and in this embodiment, tie point is made up of four directions or circular intussusception magnetic companion.The direction of magnetization of their (Internal and external cycles) is inconsistent.Two need the tie point direction of magnetization of fillet opposite.

If magnetize according to Fig. 1 the top and the bottom surface of basic building block, it has just had and the same connection possibility of mechanical LEGO building block.If at hexahedral each face (6) all is such magnetization, the diversity of connection is just more much bigger than LEGO.The tie point of side is moulded special people, it is useful when getting on that the roofing building block with certain style is fixed to basic building block.

Firm as far as possible for adhering to, the magnetic field intensity of building block upper surface should be maximum.

Obtain required adhesion, the parameter d among Fig. 1 ₁, d ₂, d ₃Or r ₁, r ₂, r ₃To select appropriately with h.Here r ₁Be the inner ring radius, r ₂Be the outer ring inside radius, r ₃Be the outer ring outer radius, d ₁, d ₂And d ₃Be corresponding to tetragonal body.Parameter h is the height of magnetic tie point.Under special circumstances, d ₃=d ₂=d ₁＞0, or r ₃=r ₂=r ₁＞0, this just only has a square or circle as effective tie point (referring to Fig. 3 and Fig. 5).Say in principle, obtain such arrangement and magnetic, but be not the thermoplastic that has only with magnetic, all known magnetic materials all can adopt.

Fig. 1,2,3 and 5 show this inventive embodiment.

As follows in detail:

Fig. 1: the magnetic knot chalaza that axial symmetry is arranged: a) tetragonal a pair of south poles, b) south poles of circumferential is right, and its geometric parameter is d ₁, d ₂, d ₃Or r ₁, r ₂, r ₃And h.

Fig. 2: a) basic building block, b) building block of demultiplication and c) outside the building blocks extraordinarily.

Fig. 3: a) all face tie point that all is magnetic, b) have only on, following two faces tie point that is magnetic.

Fig. 4: strip magnetization, a) horizontal strip, b) longitudinal strip, the N=arctic, the S=South Pole.

Fig. 5: upper surface is a) square magnetic tie point, b) circumferential magnetic tie point.

Fig. 6: press Fig. 5, the N-S of two kinds of magnetic effects of square or circumferential magnetic tie point arranges.

One embodiment of the present of invention are: the magnetic building blocks toy, have of all kinds can interconnected building block, can truly, copy simple house, a building with them with dwindling.Except can copying a single single building family housing or shotgun house (garden is arranged or do not have the garden), also can copy private buildings thing or public building with cultural and historical meaning.Make the people interested especially as buildings such as Trifel castle, Hambacher palace, Ladwigschoehe villa, Arc deTriomphe and Alhambra.

The ratio L that basic building block adopts: B: H=3: 1.5: 1, i.e. the cubic hexahedron (see figure 2) of 30 * 15 * 10mm, the arris of building block also can be handled, and makes it slick and sly and make an amendment to obtain special effect such as shade seam.

The general plastics ABS of color (as contain) are selected as carrier material, and magnetizable thermoplastic is made magnetic material.

On the above and below of building block, can embed smoothly 8 have inner and outer ring, with axisymmetric circular magnetic tie point.

Circle is as the South Pole in the upper surface, and cylindrical is the arctic, difference unidirectional magnetiztion, and the just in time opposite (see figure 1) of lower surface.

For as far as possible truly copying the front, house, can correspondingly mould (being surface texture and color) from the outside of basic building block, perhaps on the lateral surface of basic building blocks, add the magnetic tie point is set, so just can fix special roofing building blocks with magnetic.A kind of scheme in back has following advantage, promptly can construct " study " simply with it, the effect of the positive style of different buildings of can having a try apace simultaneously.

The demultiplication piece of basic building block and extraordinarily piece (as making a door beam) be needs, need in addition other forms of building block (as making cylindrical cylinder, as window and construct building blocks).

One pair of such magnetic building blocks can progressively be extended to a kind of complete " the magnetic playset world ".

It has promoted creative, building structure and has deepened understanding, particularly architectural history and art history to art.Because the effect of magnetic force also can bring the happy of many recreation.
