Description

Title: A play and instruction means
The invention relates to a play and instruction means on the basis of spherical elements, each element being an assembly of a hollow, spherical envelope, made of a non- magnetizable material, in particular a synthetic plastics material, and a permanent bar-like magnet positioned within the envelope and having headfaces curved analogously to the spherical envelope.
Such a spherical elements-containing instruction means is disclosed in German Auslegeschrift 1,239,876. These known spherical elements having a magnetic field however are composed in such a way that compliance is made with the condition imposed that the magnetic flux is:distr±bu±.edover a maximally large portion of the sphere surface. The bar-like magnets are immovably secured within the elements. German Offenlegungsschrift 30 00 567 concerns
OMPI agnetic building blocks that can be used as play means for children or also as model building blocks for e.g. architects. No requirements are set to the building blocks in respect of shape and size, nor to the nature of the material from which these are made and which may e.g. be a synthetic plastics material. One or more magnets are embedded within the building blocks and consequently likewise secured immovably.
It is an object of the invention to provide a play and instruction means of the above described type having new improved spherical magnetic elements which enable a great many new applications, both as play means and as instruction means.
To this effect the invention is characterized in that the weight of the non-magnetic material processed in the spherical element is minimal relative to the magnetic strength of the bar-like magnet.
By minimizing according to the invention the weight of the envelope relative to the magnetic strength, it is achieved that the forces to be exerted under influence of the magnetic strength can continue to be strongly active. The envelope, apart from the fact that it serves as housing for the bar-like magnet, has substantially only a spatial orientation function within the total of coating spherical elements, ensuring the possibility of a rolling movement to be performed by the spherical elements.
These two properties of the spherical elements in combination, together with the strong polarization of the magnetic effect, caused in that according to the invention each spherical element is provided only with a single bar-lik magnet, ensure that in assembling a structure by means of the spherical elements, these are optimally oriented and position ed by automatic rotation according to the magnetic force fiel As a result, also the stability of the resulting structure is optimal. On increasing weight of the envelope relative to the magnetic strength, the possibility for the spheres to choose the proper position by automatic rotation decreases and finally even disappears possibly. In such a case the builder himself would have to choose the optimal position for each spherical element within the structure by manual rotation. The chance that he will be successful however is negligible, since on addition of each successive spherical element to a structure, the entire magnetic force field prevailing between the elements already present is affected and changed. It will be clear that the possibility offered by the spherical elements according to the invention to always choose the proper position within the structure again for all elements by automatic rotation, in particular for young children, who have insufficient knowledge of magnetism, is an important aid in building with the spherical elements.
Although partly depending on the diameter of the spherical element, it is of relevance to choose the ratio between the magnetic strength and the weight of the non- magnetic material in such a way that per 500 Gauss magnetic strength the weight of the mon-magnetic material is not more than about 1 g. In practice a ratio of about 900 Gauss magnetic strength to 1 g weight of the non-magnetic material of envelope and positioning means at a diameter of the envelope of about 17 mm has been found quite manageable. According to a preferred embodiment there are provided within the envelope positioning means for the bar-like magnet connected to the envelope in such a way that within the envelope the bar-like magnet is movable in axial and radial direction along a distance that is subsidiary to the diameter of the spherical envelope. Due to this mavability of the bar-like magnet within the spherical envelope, there is afforded an extra variability in respect of the magnetic force field within a group of co-acting spherical elements. As a result, the behaviour of the spherical elements within the group becomes less predictable still, which increases the surprise as play element on application of the elements as play means. According to a further embodiment, the envelope is formed of two interconnected semi-spherical portions, while within the spherical envelope, the positioning means constitute a chamber disposed in rotational symmetry about the axis right-angled to the plane of division of the semi- spherical portions.
Partly with a view to an effective manufacture, it is advantageous when the magnet is a straight circular cylinder and the chamber has an annular radial cross-section and is made of the synthetic plastics material used for the spherical envelope.
When assembling the spherical element, the two semi-spherical portions may be interconnected in any suitable manner, e.g. by ultrasonic welding along the circumference of the chamber to be formed preferably within the envelope. It is self-evident that the semi-spherical portions to be assembled may have different colours.
According to still another advantageous embodiment the play and instruction means according to the invention is an assembly of the spherical elements and of construction elements made of no -magnetizable sheet material, provided with recesses and/or holes at an interspace that is equal to or a multiple of the diameter of the spherical element, said holes having a diameter that is sufficiently small in order that the spherical elements positioned on either side of the strip-like or sheet-like element in the same hole do not touch each other. By means of said strip-like or sheet¬ like elements, structures of various shape can be made, which moreover may comprise hollow spaces, while due to the regular distribution of the recesses and holes, numbers play a role, as will be explained in the following.
Since the envelope is made of synthetic plastics material, there is obtained the practical advantage that such a material has a given resilience and as a result is sound- absorbing. When handled by children, there is moreover less chance of receiving or causing injuries when e.g. the spherical elements are thrown at each other. Furthermore, also other coating materials may be employed, e.g. ceramic material or wood.
The round form of the elements, in combination with the strongly polarized magnetic field, when used as a toy, offers excellent possibilities to assemble the elements to structures of varying external forms, e.g. a pyramid, cube, rectangle, tower, etc., and a substantially unlimited number of free forms.
In combination of 100 of the spherical elements, divided in ten groups of ten elements each, while per group the elements have the same colour, but the elements of the various groups a different colour, the instruction material is suitable for use as a so-called three-dimensional counting frame. Consequently, the instruction means in this form is an aid in teaching children arithmetic. The instruction means according to the invention is also suitable to make letters of figures and also in case of such an application is an educational appliance for children.
The elements associated with the play and instruc¬ tion means according to the invention are all actively magnetic and according to the choice of the nature of the material from which the coating of the magnetic core is made, may be designed as substantially "north pole", "south pole" or "north and south pole" elements.
The diameter of the spherical elements is not critical and may be 0.5-7 cm,depending on the purpose for which the elements are used. If desired, however, smaller or larger diameters can be maintained.
On embodiment of an element according to the invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Fig. 1 is a cross-section of the centre of a spherical element according to the invention which is arranged in such a way that the bar-like magnet is vertical;
( OMPI Fig«-2 is'an elevational view of a strip as construction element of Perspex, provided with means for interconnecting the strips through the spherical elements; Fig. 3 shows a structure with application- 1 of strips of different lengths of the type shown in Fig. 2. At 1 and 2 are shown two semi-spherical shells made of polyethylene, said two shells having the same or different colours.
The shells 1 and 2 carry internally annular projections:3and 4 being integral with the respective shells 1 and 2 and which, in assembling the shells 1 and 2 to the ready spherical element 5, guard in con unctiona chamber 6 within which the cylindrical bar-like magnet 7 is disposed. The transverse and height dimensions of chamber 6 are larger than the corresponding dimensions of the magnet.
The shells 1 and 2 are fixedly connected to each other via a joint ultrasonically applied along the circumference of the contacting edges of the annular projections 3 and 4. The strips 8 shown in Fig. 2 and 3 are made of
Perspex. For the purpose of interconnection of the strips 8 to structures, one example of which is shown in Fig. 3,the strips 8 are provided with recesses 9 on either side and in the corresponding places. In stead of recesses also holes may be applied, as indicated by way of example by 11, or the central portion of the recesses may have a continuous hole, as likewise shown.by 10 by way of example.
For the purpose of coupling the strips to structures by means of the magnetic spherical elements, these are positioned in the recesses 9 in the manner shown in Fig. 3 , while the strip is clamped by said elements under influence of the magnetic power of attraction active between the spherical elements.
As shown in Fig. 3, an identical radius of curvature has been chosen for a spherical element and a recess, thus counter-acting a lateral shift of the strips in a structure relatively to each other. This effect can be reinforced by roughening the external surface of the spherical elements and the surface of the recesses.
In order to realize corner joints in a simple manner, the strip-like or sheet-like elements can be provided with flanged edges, of sufficient widths for accommodating therein the coupling recesses 9, or they may have a curved form.
Saturally, modifications may be applied in the play and instruction means as discussed in the above and as shown in the drawings without departing from the scope of the invention.
