Definitions

  • the present invention relates to the field of magnetic toys of the type comprising a plurality of constructional modular elements, for example of the type d isclosed in EP-A-1 .742.715, and more properly is d irected to a magnetic joint device, hereinafter referred to as "magnetic joint" for toys comprising modular constructional elements, said magnetic joint being suitable for enabl ing a greater assembling and anchoring freedom and capability between two or more constructional elements of a toy.
  • toy assemblies can be achieved in a very flexible manner, having two/three-dimensional geometric shapes, for example for reproducing monuments, castles, general buildings, static and/or dynamic toys and structurally simple or complex toy assemblies imitating real environments or environments of mere fantasy.
  • Meccano is characterised by a connecting system of point type, wherein planar metal bars are provided with a plurality of holes, spaced apart by a constant step, and wherein the connection between the bars is obtained by nut and bolt means in which the balls must be inserted into aligned holes of two or more partially overlapped bars.
  • this connecting system enables a relative rotation between the bars only, when bolts and nuts are not strongly tightened; in addition, the position, the orientation and the connection between the bars of a toy can be only adjusted in a plane, at the single holes.
  • “Lego” consists in turn of a plurality of small bricks of plastic material, suitable for being fixedly engaged with each other; each brick exhibits, on opposite sides, protrusions and/or cavities wherein the protrusions of a brick engage the cavities of one or more bricks; protrusions and cavities are allowed to fixedly engage each other only at two opposite sides preventing any relative movement.
  • Geomag is disclosed, in some possible embodiments and applications, in EP-A-1 .080.476 and E P-A-1 .742.71 5.
  • I n particu la r E P-A-1 .080.476 concerns a magnetic toy assembly comprising metal spheres and magnetic bars, that are suitable for enabl ing the construction of two- and three- dimensional structures, characterised by closed magnetic circuits, i.e. circuits such to remarkably increase the magnetic anchoring force.
  • the Geomag system although the spheres allow the magnetic bars of the toy assembly to be rotated and oriented, such rotation and orientation are only enabled around the spheres themselves.
  • EP-A-1 .742.715 that constitutes the State of the Art closer to the present invention, suggests in turn a different implementation and use of the spheres and the magnetic bars of EP-A-1 .080.476.
  • EP-A-1 .742.71 5 discloses a toy assembly comprising a plurality of constructional and modular elements of non-magnetic material, suitable for being composed, having both structural and aesthetical functions, in which the modular elements are conformed and suitable for being combined in order to obtain any type of structure, in the construction of a toy assembly, in relation to the aesthetical features and the geometrical shape of said elements, depending on the combination and the arrangement of said modular elements during the construction of a toy.
  • the constructional elements of the toy are held in an assembled condition by magnetically connected elements defining a support skeleton consisting of magnetic bars, removably inserted into through holes of the constructional elements of the toy, and metal spheres and/or ferromagnetic block elements, disposed between adjacent constructional elements of the toy.
  • the mag n etic connecting system provided by the bar sphere elements although on one hand enables the construction of different types of toy assemblies, provided with a suitable support magnetic skeleton for connection between the constructional elements, on the other hand restricts once again the modularity and the capability of freely varying the relative disposition and orientation of said constructional elements.
  • Other modular magnetic toys are disclosed for example in US-A-1 .236.234, US-A-3.998.004, US-A-6.626.727 and US-A-6.969.294.

  • WO2008/043535 discloses the use of constructional elements for toys of different shape and type, comprising magnets movable in appropriate cavities, arranged at specified contact regions.
  • the points or the regions for mutually contacting and magnetically anchoring the elements of the toy must always be pre-establ ished at the design ing stage, without any capabil ity of successively changing or modifying said anchoring points or regions in order to adapt said points or regions to the different assembling requirements during the construction of a toy.

  • a further object of the invention is to provide a magnetic joint device suitable for connecting constructional elements of a toy, as previously defined, by means of which the various elements of the toy can be differently positioned and/or oriented in an assembled condition, according to one or more directions and/or planes, as well as two or more elements of the toy can be anchored with each other, at one or more contact regions or points, by enabling at the same time a possible relative rotation of each constructional element of the toy, with respect to a longitudinal axis of the same constructional element.
  • a further object of the invention is to provide a constructional assembly for a composable toy comprising a plurality of modular constructional elements and a plurality of magnetic connecting elements, wherein the constructional elements of the toy are similarly and/or variously conformed or shaped, and suitable for being selectively combined with each other, so as to be securely held in an assembled condition by magnetic joint devices according to the invention.

Abstract

L'invention concerne un ensemble d'éléments de construction avec des éléments d'assemblage magnétiques pour former un ensemble de type jouet, chaque élément de construction (10) du jouet comportant un corps réalisé en un matériau non magnétique, ayant au moins une rainure longitudinale (16) sur au moins une surface latérale (11), et au moins un trou traversant (15) s'étendant entre des surfaces d'extrémité (12), de manière parallèle à un axe longitudinal de l'élément de construction (10). Une broche métallique coulissante dans le sens axial (18), réalisée en matériau magnétique conducteur, est insérable de manière amovible dans une rainure longitudinale (16) d'un premier élément de construction (10.1) ; une barre magnétique (19), insérée de manière amovible dans un trou traversant (15) d'un second élément de construction (10.2) du jouet, est ancrée de manière magnétique, au niveau d'une extrémité de celle-ci sur la broche métallique (18) se trouvant à l'intérieur de la rainure (16) du premier élément de construction (10.1) du jouet.
