Abstract

The recreational teaching toy has a light spherical core (1) forming an object composed of eight octant pieces (6). These pieces are mounted on a set of eight supports, each of which are provided with assembly parts. The core is sub-divided by three orthogonal and perpendicular axes which define six equi-distant points (11), eight hollow spherical triangles (12) and eight hollows (13). Seven supports are movable without rotation and the eighth is fixed. There are six guide parts fixed to the equi-distant points coupled to the core. These guides have shock absorbing springs and a retractable stop allowing redirecting the displacement of the movable pieces.

Description

The invention, as set out in the title, relates to a TRAINING APPARATUS WITH MULTI-COMBINABLE SKILLS, from type integrated by a regular dihedral body, preferably, a spherical or hexahedral block subdivided into fractions multiples that can move - move, by the action of hands around it, following the development of its coordinate axes, and independently of each of the planes of under division of the sphere or hexahedron.

The object of the invention is the simplification of the internal structure of the toy harmonizing a series of parts which invariably will be the same for different external expressions or manifestations of the toy. Indeed, all the interior parts of the set are unchangeable, and therefore only parts of covering, showing the visible side of the toy, will designed and molded with one part of the "puzzle or break - heads "configuring the assembly, depending on the version of the whole, character, animal or thing reproduced.

And, according to the invention, these covering parts, showing the visible side of the toy, will necessarily have a exact base portion, proportional to the spherical volume or hexahedral of the whole, more precisely one eighth of this one, with an equal and compulsory basic drawing, and, also necessarily, with the same means of support or anchoring in all cases.

STATE OF THE ART

The essential foundation of the invention is based on the PCT / ES92 / 00066, subsequently converted to EP 92918614.6, with international application number of WO 94/04235.

From US-A-4 405 131 (column 3, line 12 to column 4, line 27, figures 1 - 8) is known a recreational apparatus didactic, which consists of a nucleus (14) on which structure and assemble a set of eight pieces which include a base equivalent to one octant of sphere, seven of the pieces (22) being mobile and a fixed (28), all comprising means to receive eight cover pieces (11) forming the volume circumscribed at the nucleus (14), and defining a set reproducing a specific object, this device being characterized by the fact that the nucleus (14) is subdivided by three planes orthogonal to each other, and which define six equidistant points forming housings (17), six guide (19) fixing to the points forming housings (17); eight support pieces (22, 28), seven of which are movable (22) and a fixed (28), which are guided and held by the members guide (19) and its provided with male means (27, 32) for assembly, with eight external cover parts (11) each equivalent to one octant of the external body.

The starting point is the same concept: a nucleus internal spherical, with six shoring or fixing points, orthogonally perpendicular to each other.

A set of six identical pieces supported in the six The above points serve as a guide for the support pieces.

A set of eight equal support pieces composed of an exact portion of body subdivision (spherical - hexahedral) of the whole.

A set of eight support pieces, one of which is fixed, and the other seven, moving, the first of which serves as pivot for moving others into orbit.

And, eight pieces of cover, covered with means for anchors on the support parts, and which move at the same time time as these, and which also have an exact serving to the subdivision of the whole and each of which has an external part of the object reproduced by the volume.

The general concept of operation is the same.

The fractionation of the portions, proportional to the shape and volume of the nucleus, will be basically in shape and proportions equal to this.

The mechanisms, too, respond to the same idea functional.

Yet all the structural aspects of the parts, drawing and details of detail are original, according to the development of inventive step.

INVENTIVE ACTIVITY

One of the ideas of the invention is the proposal of a nucleus which, while respecting the original spherical format, has a much lighter structure is either conditioned for allow - on the one hand - to admit the means of shoring up guide parts, and, on the other, at various points, for the mounting of the support parts acting as a pivot for the rotation of the other support parts.

Another idea of the invention is that the organs of guide for moving the moving support parts are supported by elastic shock absorbers, thus providing these parts with a mounting in conditions floating thus facilitating rotational movement and now guiding the parts in question, preventing them from get out of its corridors or runways.

Another idea is that the fixed support pieces or pivoting can be immobilized in one of the sub octants division of the nucleus.

Another idea of the invention is to provide the nucleus in one of the octants (more precisely, the opposite or antagonistic at the front) of a wedge provided with retracting means for stopper and guide for sliding the supporting parts moving.

Another detail of the invention is that each of the movable (seven) and fixed (one) supports include means male studs for covering parts and formation of the external body of the whole, while being these in turn provided with female means adjustable to pressure and bayonet in such assembly means.

DESCRIPTION OF THE INVENTION

One of the characteristic details of the invention as defined in claim 1 is that the nucleus mentioned (spherical - hexahedral) is a body semi-hollow, light, subdivided orthogonally into six coordinated planes, perpendicular to each other, combined by groups of two, parallel and equidistant from each other, and delimiting six diametrically entering prismatic housings shoring opposites and eight triangle - spherical sectors (octants) with eight dead hollow spaces between them.

Another detail of the invention is that the six housings (females) prismatic - shoring entrants are partially filled, have a square section slightly truncated towards the bottom to which a blind hole has been provided for support, for example, of a screw, button o similar, threaded for fixing of said points of the guide members for the parts support frames.

A characteristic of said guide members is that it these are "T" pieces with square base and profile adjustable spherical to the surface of the nucleus and prismatic shaft cashable at the female prismatic points of the nucleus and axially fitted with a staggered through auger for housing a button that will attach from the far bottom to the hole blind of each prismatic housing of the nucleus.

A characteristic detail of the button or attachment means guide members is that it has a mixed profile ending in a mechanized (threaded) point for fixing to the plugged prismatic housing button and a seat between the head and this point for housing a spring acting in shock absorber so that the square head of the guide member walking on the skids (bases) of moving parts without make it more difficult or prevent his movements (sliding).

A feature of moving support parts is that they are constituted by a mixed one-piece body, having an equivalent triangle or spherical base or support to an eighth part of the sphere (hexahedron), hence (equicenter) projects a cylindrical pier with diameter decreasing staggered and provided with tangential nerves Equidistant generators acting as pins or recessed studs for mounting the outer cover parts.

Another feature of moving parts mentioned support is that their bases or support pads, by the lower plan, present three chains or radial and equal lowerings between them, directed in the center of their respective sides and open by their extremes, which allow the parts to be guided again in their displacement going beyond the retractable stopper, which is placed at an antagonistic point to the part acting as a pivot of rotation.

Another characteristic detail of the support piece fixed holding the role of rotary pivot is that it is made up equally of the moving support parts, the difference being that the bottom plane of the base or skate support does not have radial channels or lowering, but, on the other hand, a concentric salient with equal format and dimension as the triangular hollows of the nucleus and encrusted in one of them of immobilized form, constituting in organ pivot around which the other seven parts move moving support.

Another aspect specific to the invention is the incorporation of a retractable conditions buffer or retractable, located in an antagonically opposite point to the pivot or fixed support part, also located and cashed in the triangular hollow of the respective nucleus. This stopper allows the moving part to be stopped support in its displacement. But a slight pressure from push allows to go beyond the bumper which is hidden or retracts and emerges or rises when the pressure rises.

A characteristic detail of the stopper is the fact that it found constituted by a ball which undergoes the pressure of a spring and is housed in an auger with a flared mouth fitted with a small heel or wedge which has a format triangular and which adjusts to pressure in one of the hollows triangular of the nucleus, more precisely in the hollow antagonistic to the pivot of rotation. The pressure of the spring which is located below the ball and contained in said triangular hollow of the nucleus, permanently pushes the ball which, due to the flared mouth of its housing, a small spherical helmet emerges or comes out,

Another aspect which is specific to the invention is that eight external cover pieces are arranged or fixed by casing, by socket assembly (at bayonet or other) in the male piers of the seven pieces and the fixed support. These eight pieces include a octant of the whole body and, each, a portion proportional, regular or irregular, of the object reproduced or represented.

A characteristic detail of the cover pieces mentioned is that they are integrated by a shield triangular (hexahedral) of the toy), provided inside and axially of a cylindrical hoop suitably reinforced with a shaped female cut of star assembly with the profile of the male pier of moving parts - fixed support.

Obviously, the outer part of the shield presents the portion, suitably decorated, drawn or represented, of the estimated reproduction of the set, what whatever the object that it manifests.

A broader idea of the characteristics of the invention will be given later, when considering the blade of drawings which is part of this thesis, where, so slightly schematic and only as an example, show the preferred details of the invention.

DESCRIPTION OF THE DRAWINGS

With regard to these illustrations (fig. 4), the spherical nucleus is generally indicated with (1); the guide member (Figure 5) for the moving parts of support, and is flagged with (2); these moving parts (figure 6) with (3); the fixed support part / (FIG. 7) with (4); the heel or wedge for the retractable buffer with (5); a piece external cover (figure 9) with (6) and the fixing the guide members (2) (figure 10) with (7).

The nucleus (1) (figure 4) constituting the central organ for the development of the toy body is composed by a semi-hollow spherical body ballast of mass, subdivided by three parallel and equidistant double planes (10 - 10a - 10b) distributed orthogonally along their axes of coordinates, and configuring six prismatic housings (11) to support the guide members (2) (Figure 5); eight videos or hollow triangle - spherical (12) which serve as accommodation, at least, for the fixed support piece (4) (Figure 7) and the bumper heel or wedge (5) (figure 8) and eight spaces dead (13) in the intersection of others and others to allow decrease in body mass.

The prismatic housings (11) have a depth medium, and, at the bottom, a suitably threaded blind hole to allow the fixing of the button (7) (figure 10).

Said housings (11) count with the organs of guide (2) (figure 5) held by six buttons (7) (figure 10) and with the interposition of a spring (8) (figure 10) acting as a shock absorber according to Figure 2.

The guide member (2) (Figure 5) is a whole piece in (T) of square plant, spherical arc (20) with arc sides concaves (21) and a vertical prismatic barrel (23) with cross-section - square for its housing in (11) with cylindrical interior hollow (24) finished in a smaller diameter auger (25) passing for passage of the button (7) (figure 10) and a upper mouth with seat (22) for the button head mentioned (7).

The four sides (21) with the square head or plant (20) support the coincident dots of an equal number of bases moving parts - fixed support (3-4) (Figures 6-7), serving as guides to extend the movement of moving.

The eight moving support pieces - fixed (3-4) (figure 6-7) have a similar configuration, but a function different. Indeed, the seven moving parts (3) slide or move by manual action on the six planes moving of the sphere, and the remaining part (4) remains fixed, serving as an eccentric pivot for rotation to others.

The seven moving support parts (3) (Figure 6) are composed by a one-piece mixed body, base or support of equilateral triangle support (30) with convex sides (31) of bevelling in the chanfrain plane (36) descending or leaving towards the lower shot.

This plane less than three radial channels or lowering (32) projected towards the center on each side (31) and open by their respective extremes, and whose intersection coincides with the perpendicular external projection of a pier rising vertically (35) and staggered sections decreasing ascending (34) also counting with tangential and generative ribs (35) at 120 ° constituting the male means for assembly and support of the external parts of cover (6) (Figure 9).

The fixed support piece (4) (figure 7) offers parts identical (40 - 41 - 43 - 44 45 and 46) to the parts respective analogs (30 - 31 - 33 -34 -35 and 36) of the part anterior (3).

However, the bottom plane of your base (40) is covered by a concentric projection (42) forming a cane allowing to collect the coin in one of the triangle hollows - spherical (12) of the nucleus (1) (Figure 4).

The hollow (12) diametrically opposite or antagonistic to the mounting location (12) of the fixed support part (4) (figure 7) used to install the heel or retractable stopper cane (5) (Figure 8).

This heel (5) is composed of a simple equilateral triangle piece (50) with arc-convex sides (51)
chamfer plane bevel (52) entering or running inward, wedge-shaped, to adjust to the triangle-spherical hollow (12) of the core (1) being provided with a central hole (equicentric) (53) , with an upper mouth (54) bevelling in a chanfrain plan flared outwards.

This hole is used for housing the ball (9) which undergoes the spring pressure (90). The ball partially emerges in a portion equivalent to a spherical helmet by the flared ball (54).

The male jetties (33) of the seven moving moving parts (3) and the male jetty (43) of the fixed support piece (4) are used to mount the eight external cover parts (6) (figure 9) which will conform the external body of the assembly or the body of the toy itself.

The outer cover pieces (6) are basically equal. They are all composed of triangle - spherical fragments (60) corresponding to a octant of the external development of the (spherical) body of the toy. With its arc - convex sides (61) and the edges of this in beveled chamfer entering (62) and provided inside and centrally of an appendage (63) radially reinforced with 120 ° ribs (64) and internally provided a female notch (65) also with 120 ° grooves for assembly of the support pieces (3 and 4) at the jetties (33 - 43) (Figures 6 and 7). It is ultimately an assembly connected to bayonet.

The outer part of the part (6) comprises a portion external (66) of the object represented by the assembly. This shows the "ear" of an animal head, reproduced by all.

The button (7) (figure 10) serving as fixing for the guide member (2) (Figure 5) consists of a outgoing fitted with head (70) is finished in a blocked area mechanized (71), and between one and the other forms a neck (73) delimited by the head (70) and a seat (72) where a spring (8) (figure 10 - E) serving as cushioning for the head (20) of the guide member (2).

OPERATION

The whole unit is armed with the nucleus structure (1), the volume of the assembly can have the same spherical shape of the nucleus (1) or another equivalent polyhedral geometrically.

The housings (11) are used for mounting the six guidance (2) using buttons (7) with incorporation of spring (8) (figure 2). Each side (21) of the head (20) of the organ in question walk simultaneously on two summits contiguous bases (30 - 40) of the supports (3 - 4) moving and fixed.

The seven moving supports (3) are mounted on the surface of the nucleus (1) allowing movement by action manual.

One of the triangular hollows of the spherical nucleus is used for mounting of your fixed support piece (4) irremovably. The antagonic hollow (12) used for mounting the heel or door wedge - retractable stopper (5) with ball (9) and spring (90).

Once the internal skeleton of the toy is structured, the one - it overlaps with eight equal octants (6) assembled by connection by the jetties (33 - 43) of the support parts (3 - 4), forming the external body of the whole, obviously circumscribed to the nucleus.

a): la pièce (4) agit en pivot rotatif des pièces mouvantes restantes (3).

b): le butoir (9) permet le contrôle de la limite de tournée, et il est possible de varier le sens et le reconduire à l'aide des canaux radiaux (32) des pièces mouvantes (3). De tels déplacements permettent de placer chaque partie externe (6) au lieu correspondant pour former correctement l'objet que le jouet reproduit. Tout ceci demande évidemment une certaine habilité, vision et sens mathématique pour l'obtenir de manière rapide et efficace.

The mobile condition of the seven parts (3) allows it to move in three directions (10 - 10a - 10b) of the orthogonal division of the nucleus (1), thanks to the movement of the semi-spherical helmets delimited by these divisions or:

a): the part (4) acts as a rotary pivot of the remaining moving parts (3).

b): the stopper (9) allows control of the travel limit, and it is possible to vary the direction and extend it using the radial channels (32) of the moving parts (3). Such movements make it possible to place each external part (6) at the corresponding place to correctly form the object that the toy reproduces. All this obviously requires a certain skill, vision and mathematical sense to obtain it quickly and efficiently.

Once the nature of the invention has been properly described, it should be noted, with timely effects, that it is not limited to the exact details of this exhibit, but, on the other hand, it will allow the introduction of modifications deemed suitable, always on condition of not altering it the essential characteristics which are claimed below - below.
