Abstract

Self-braking marble, of the type that includes a spherical body, characterized in that it has a central hollow (2) with a plurality of lateral housings (3) and an internal ball (4), enabled for free movement between said housings (3) sides through the central hole (2), to define a variable center of gravity that causes the marble to brake during the movement of the marble and because the spherical body has ornamented areas (9) on the outside in a diametrically opposite arrangement to the accommodation (3).

Description

Self-braking marble.

Object of the invention

The present invention relates to a marble self-braking, usable as a toy for children.

Background of the invention

The game of marbles has been known since ancient times by children. These marbles are constituted generally by a spherical body of reduced dimensions, and preferably of rigid materials, such as glass, ceramics, metal and others, being able to present an ornamentation embedded in its interior, as is the case with transparent marbles or translucent

The games usually consist of crashing the different marbles of the players with each other, using the ground or any other more or less horizontal surface as a space of game.

However, the urban environment, in which Today's children usually move, it makes the surface of game stop being the traditional dirt floor, irregular and full of stones and mounds. Instead, it is currently played on paved ground, very smooth pavements or on tables and others surfaces of remarkable regularity or flatness; this makes the game as it is known, because the absence of irregularities and earth or loose sand causes marbles thrown or pushed roll without brake and without the possibility of stopping or being with obstacles that influence its progress, making the Marble movement is uniform and hard to control on the tour

Description of the invention

The self-braking marble, object of this invention, presents some technical peculiarities, destined to provide an irregular displacement when launched or pushed, even if such displacement occurs on a completely smooth and flat surface, thus allowing to introduce a complexity in the actions of the players and an action of braking during the movement of the marble.

The marble of this invention has a body spherical with a central hollow provided with a plurality of lateral housings and in which a ball is housed, with the possibility of free movement between the different lateral housings through the central hollow, defining a variable center of gravity of the marble.

This variable center of gravity allows the self-braking marble travels, once launched, a shorter distance than that of a conventional marble, especially when said marble is thrown on a smooth and regular surface. Thus it is possible to play with these self-braking marbles on very surfaces smooth and flat without excessive travel.

In an embodiment example the housings laterals are defined by emerging wall partitions inside the spherical body, which is constituted by a fine outer shell, for example. The central passage of the ball between the different housings is defined by the edges superiors of said partitions.

These side housings may present some inner stops at the bottom that prevent the ball from excessively enter them, which could make your change of position towards other attached accommodation. With these stops you get the inner ball to have a greater or lesser predisposition to change from one accommodation to another, and therefore The marble slows before.

In order to offer a more playful character of the marble, the spherical body has ornate areas outside it in an arrangement opposite to the housings. Thus, the marble has a greater utility, since the player can use it with other marbles, and can use it alone as a game by throwing it. In addition, these ornate areas allow the identification of different marbles and their use as collectible and interchangeable objects between
players.

In a preferred embodiment the spherical body it is constituted by two halves joined by means complementary of union. This construction from two hemispheres allows you to easily insert the inner ball and its subsequent closure. These complementary means of union are preferably a set of appendages and conjugated entrees arranged on the opposite faces of both halves, with which close the spherical body of the marble by simple pressure.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view of the marble.

- Figure 2 shows a plan view of a of the halves of the marble.

- Figure 3 shows an elevation view sectioned from both halves of the marble.

- Figure 4 shows a perspective view of the open marble.

Preferred Embodiment of the Invention

As can be seen in the referenced figures, the self-braking marble is constituted by a spherical body consisting of two halves (1a, 1b) between which a central hole (2) is defined, which has a plurality of lateral housings (3), in which a ball (4) of a heavy material is arranged freely movable, such as
ro.

The two halves (1a, 1b), of constitution hemispheric in this case, they present in their complementary faces complementary means of union, more specifically ones appendices (5) and conjugated starters (6).

The lateral housings (3) and the hollow central (2) are defined by emerging partitions (7) of the inner wall of the spherical body, the gap being defined central (2) of passage of the ball (4) between the different housings (3) by the edges of said partitions (7). At the bottom of the side housings (3) there are defined stops (8) which prevent excessive entry of the ball (4) into said accommodation.

On the outer face of the spherical body it they find defined ornate areas (9), available opposite to the housings (3) for its visible arrangement when the marble stops and the ball (4) is partially housed in the accommodation that occupies the lower position, determining a stable marble position.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.

Claims (5)

Self-braking marble, of the type comprising a spherical body, characterized in that it has a central hollow (2) with a plurality of lateral housings (3) and an inner ball (4), enabled for free movement between said housings (3 ) lateral through the central hollow (2), to define a center of variable gravity that produces the braking of the marble during the movement of the marble and because the spherical body presents in its exterior ornate areas (9) in diametrically opposite arrangement to the accommodations (3). 2. Marble according to claim 1, characterized in that the lateral housings (3) are defined by partitions (7) emerging from the inner wall of the spherical body, the central passage (2) of the ball passage (4) being defined between the different housings (3) by the edges of said partitions (7). 3. Marble according to claim 1, characterized in that the lateral housings (3) have inner stops (8) for introducing the ball (4). 4. Marble according to claim 1, characterized in that the spherical body is constituted by two open halves (1a, 1b) joined by complementary joining means. 5. Marble, according to claim 4, characterized in that the complementary joining means are a set of conjugated appendages (5) and inlets (6), defined on the opposite faces of the two halves (1a, 1b) of the spherical body
