TECHNICAL FIELD

The present invention is encompassed within the field of games of skill, and more specifically, it relates to a cylindrical labyrinth designed to lead a ball between an entry point into a labyrinthine path and an exit point therefrom.

BACKGROUND ART

There are several labyrinth-type games of skill that are currently known, where the user must lead a ball between an entry point and an exit point through a labyrinthine path arranged between said points.

The most usual of these include two-dimensional labyrinths, or 2D labyrinths, which may adopt different shapes, the most usual of which being rectangular or circular. These labyrinths comprise a fixed labyrinthine path that does not admit any modifications from the user. Once the game is solved the first few times, users acquire the necessary knowledge to complete it successively as often as they wish in a mechanical and repetitive manner, losing with it interest in the game.

Three-dimensional labyrinths or 3D labyrinths, which mainly adopt a cylindrical shape, are much less frequent. These labyrinths comprise a dynamic labyrinthine path that can be modified by the user in order to face a different challenge every time he or she plays the game. They are generally formed by a plurality of cylindrical bodies and a longitudinal shaft, where said longitudinal shaft is configured to pierce and align the cylindrical bodies and to allow the rotation thereof with respect to said shaft. Each cylindrical body presents an outer wall with a labyrinthine path configured to be traversed by a ball between an entry into the labyrinthine path and an exit therefrom. The individualized rotation of each body allows the user to modify the route of the ball during the game between a starting point and an ending point thereof.

However, existing cylindrical labyrinths present important inconveniences that affect the correct operation thereof and that dull the game. In that sense, the labyrinthine path of each body is constituted by a channel engraved in the outer wall thereof, partially embracing the ball to prevent it from flying out of the labyrinth. These channels make it difficult for the user to correctly see the ball during the game, cause the ball to often get stuck in any section, especially those comprising straight angles, accumulate dirt and complicate the manufacturing of the labyrinth.

The cylindrical labyrinth of the present invention solves the aforementioned problems by providing a transparent cover for each cylindrical body, which allows having wider channels through which the ball is able to pass more smoothly without flying out from the labyrinth. In addition, the labyrinth of the present invention presents an improved structural configuration that facilitates the mounting and usage thereof by the user.

SUMMARY OF THE INVENTION

The cylindrical labyrinth of the present invention comprises:

• • a plurality of cylindrical bodies, where each one of them presents an outer wall with a labyrinthine path configured to be traversed by a ball between an entry into the labyrinthine path and an exit from the labyrinthine path; and
  • a longitudinal shaft configured to pierce and align the cylindrical bodies and to allow the rotation thereof with respect to said shaft.

Said labyrinth is characterized in that each cylindrical body comprises a transparent cover configured to cover the outer wall of said body and to prevent the ball from falling out from the labyrinthine path thereof. This way, the channels of the labyrinthine path can be as wide as necessary in order for the ball to run smoothly. And therefore, the ball does not need to be partially embraced in order to prevent it from flying off, which reduces its mobility.

The interpretation of transparent extends to any type of material that allows seeing the ball through the same, in a more or less clear or even translucent manner.

Materials enabled for said purpose can be used to achieve the foregoing, which should preferably be plastic, tinted or non-tinted, partially covered with adhesives or any other type of decorative element that improves the aesthetic appearance of the labyrinth.

Preferably, the shaft comprises a first end that presents introducing and retaining means configured to facilitate the introduction of the shaft into the cylindrical bodies and to prevent the detachment thereof once pierced and aligned. The introducing and retaining means in turn comprise a truncated cone-shaped flange with a descending diameter according to the direction of introduction of the shaft into the cylindrical bodies, which works together with an axial empty space to facilitate said introduction and that presents a retaining wall configured to prevent the detachment of the shaft from the cylindrical bodies.

The cylindrical bodies can be mounted on the shaft in a direct or an indirect manner. According to an indirect mounting form, the labyrinth comprises an axial adapter configured to remain affixed to the interior of the cylindrical body and to be pierced by the shaft, allowing the rotation thereof. The axial adapter comprises an inner hollow cylinder presenting a through-hole configured to be pierced by the axis; a plurality of radial arms that present adaptation ends configured to fit in affixing slots arranged on an inner wall of the cylindrical body; and an intermediate hoop connected to said radial arms.

In order to prevent slacks between adjoining cylindrical bodies that could affect the correct development of the game, the labyrinth comprises a closing ring configured to be inserted in the shaft and to ensure an axial tightening on said cylindrical bodies. The closing ring comprises a V-shaped transversal tear that presents a corner aimed towards the interior of the closing ring and that extends along the length of an outer cylindrical sector thereof; and a protuberance in a frontal face of said closing ring in an angular position matching the larger opening of the transversal tear.

In turn, the shaft comprises a second end that presents auxiliary tightening means configured to work together with the closing ring and to favor the axial tightening on the cylindrical bodies. The auxiliary tightening means comprise a head configured to adjust the closing ring against, the cylindrical body.

In order to facilitate the mounting of the cover, the labyrinth preferably comprises connecting means between the cylindrical body and the cover configured to join the cover to the cylindrical body and to prevent a relative rotation between the same. The connecting means comprise a relief in the cover configured to be housed in a recess of the cylindrical body, where said recess is located between the outer wall and a frontal wall of the cylindrical body.

The labyrinth comprises a top that presents closing means configured to fit in the cylindrical body. Preferably, two tops are arranged, one at each end of the labyrinth, which independently constitute the starting point or the ending point of the game, given that the labyrinth is reversible and that the game can be played from either direction.

The top comprises a transparent closing cover that encloses a cavity configured to house the ball, through which said ball can enter and exit the labyrinthine path of the cylindrical body. The closing means comprise a plurality of tabs perpendicular to the closing wall, which ends present a truncated cone-shaped flange with a descending diameter according to the direction of introduction of the top into the cylindrical body, and which presents a fastening wall configured to prevent the detachment of the top from the cylindrical body. The fastening wall is configured to fit with the intermediate hoop of the axial adapter.
