FIG. 1 shows a plan view of a preferred embodiment of the two-piece toy; -
FIG. 2 shows a side view of the first and second magnets and their respective pole orientations: -
FIG. 3 shows a more detailed plan view of the second part of the toy; -
FIG. 4 shows a side elevation corresponding toFIG. 2 ; -
FIG. 5 shows how the position of zero field strength varies with α; -
FIG. 6 defines an angular parameter (α); -
FIGS. 7( a) to 7(d) show alternative shapes (plan view) for the first part of the toy; and -
FIGS. 8( a) to 8(h) show various alternative configurations for the first and second magnets (without a cradle) for the second part of the toy. - A preferred embodiment of the invention will now be described by reference to
FIGS. 1-4 .FIG. 1 shows a magnetic toy (10) comprising a first part (12) with a single magnet, and a second part (14) comprising a plurality of magnets. In use, the first part of the toy (12) may be moved by means of the second part of the toy (14). One of both of these parts may be housed within or attached to a play article; such as an animal or vehicle. In use, the first part is moved (pulled or pushed) only by means of magnetic forces between the first and second part. Thus, in use there is no need for physical contact between the two parts. Thus, the two parts (12,14) attract or repel one-another merely as a result of varying the distance between the two parts. - The first part (12) may comprise simply a cylindrically shaped magnet.
- In this preferred embodiment, the second part (14) comprises a central cylindrically shaped magnet (16) with six smaller cylindrically shaped magnets (18) held in a fixed configuration around the central magnet; in this case equally spaced around the perimeter. As illustrated (see
FIG. 2 , where the depth of the second magnets has been reduced for clarity of illustration) the six smaller surrounding magnets each have their South-poles uppermost and the larger central magnet has its North-pole uppermost. Thus, the magnetic field produced by the central magnet (16) opposes the magnetic fields produced by the six smaller surrounding magnets (18). - The surrounding magnets (18) can be bonded to the central magnet (16). However; it is preferable for the magnets to be held in their desired fixed configuration by means of a cradle or the like.
FIGS. 2 and 3 show such a cradle (20). The cradle (20) comprises an inner hollow cylinder (22), surrounded by an outer hollow cylinder (24); the outer hollow cylinder (24) is held in a concentric position relative to the hollow cylinder (22) by means of six square frames (26). These frames are preferably spaced at equal intervals around the annulus formed between the inner cylinder (22) and the outer cylinder (24). The inner and outer cylinders may be attached to the six cradle frames (26) by any suitable means, such as adhesive, welds etc. The inner cylinder (22) is preferably sized such that the central magnet (16) is a tight push fit. Likewise, the six square cradle frames (26) and thus the outer cylinder (24) also are sized such that the six surrounding magnets (18) are also a tight push fit in the frames (26). Alternatively, the cradle frames may be circular or elliptical (plan view) in shape. Optionally, the cradle may have lower and upper disc-shaped covers attached thereto (not shown) that in use sandwich the above described (16, 18, 22, 24, 26) parts. Alternatively, the cradle and magnets may form the base portion of a figure or plaything. - The combination of magnets (16, 18) used in the second part (14) combined with their pole strengths; the orientation of their poles; and their relative placement results in the second part (14) producing an overall magnetic field that corresponds to a north-pole at a point in close proximity to the second part (14); the field strength rapidly decreasing to zero (at a point X mm from the second part) and at greater distances (than X) produces a magnetic field that corresponds to a south-pole.
- In an example according to the above all of the magnets are cylindrically shaped and 6 mm deep. The central magnet (16) is 20 mm diameter and the surrounding magnets are 6 mm diameter. They are all neodymium magnets; the central magnet has a maximum lift of ca 6.6 kg and the surrounding magnets each have a lift of ca 1.1 kg. The first part (12) comprises a 20 mm diameter, 6 mm deep cylindrical neodymium magnet. For the above configuration
FIG. 5 shows how the distance (measured from the centre of the central magnet) at which the field strength is zero varies with angular position (zero degrees corresponding to a straight line passing between the centre of the central magnet and the centre of a surrounding magnet). For clarity,FIG. 6 illustrates the above definition of angular position (α). -
FIGS. 7( a) to 7(d) shows alternative shapes (plan view) for the first part (12). -
FIGS. 8( a) to 8(h) show alternative configurations of the central magnet (16) and of the surrounding magnet (18) for the second part (14) according to further embodiments of the invention. Thus, a circular central magnet may be partially surrounded by 2, 5, 6, or 7 smaller cylindrical magnets (seeFIGS. 8( a) to 8(d) respectively). A circular magnet may also be surrounded by an annular-shaped magnet (seeFIG. 8( e)) or largely surrounded by a horseshoe-shaped magnet (seeFIG. 8( f)). Alternatively a circular magnet may be partially surrounded by a plurality of non-circular magnets (seeFIG. 8( g)). The central magnet need not be circular in cross section; for example it may be polygonal (seeFIG. 8( h)) and in such cases the surrounding magnets may be polygonal in shape (cross section). - The second part is normally configured such that the circular-shaped (or polygonal) base faces of the first and second magnets lie on substantially a single plane. The bases of the first part and the second part lie on single plane. In use, the bases of the first part and the second part will normally be placed on a substantially planar surface; often a horizontal surface.
- As the first part (12) is moved towards the second part (14) they will initially attract one-another, but eventually as they get closer (than distance X) they will repel one-another. Hence, when the two parts are on a flat surface, the first part can easily be used to move the first part in any direction without any danger of the two parts being pulled into contact with one-another as a result of their respective magnetic fields.
