(a) Field of the Invention
The present invention relates to a balance plate intelligent game apparatus that enables both feet to tread on a balance plate, and left and right swinging of the body causes a ball to continuously roll within two tiered helical tracks.
(b) Description of the Prior Art
A ball disk of a conventional balance plate game apparatus is only provided with a single tier structure and a helical groove track within the ball disk only enables a ball to roll within the single tier track, and is thus only provided with a simple balance function that lacks any other purpose.
A primary objective of the present invention is to provide a lower tier balance plate and an upper tier ball disk each with a helical groove, thereby forming upper and lower tier track grooves therein, with a hole forming an interlink between the upper and lower track grooves. With such a configuration, a ball is able to roll from the lower tier helical track to the upper helical track, and then drop into the hole of the upper tier and enter a falling ball area of the lower tier track. When a young child treads on the balance plate, a swinging movement of his body causes the ball to continuously roll within the upper and lower track grooves, thereby training movement of the limbs and trunk to control balance and eye and feet coordination.
To enable a further understanding of said objectives and the technological methods of the invention herein, brief description of the drawings is provided below followed by detailed description of the preferred embodiments.
Referring to
A transparent upper tier ball disk 20 is installed on the lower tier balance plate 10, and a helical groove 21 is formed on the ball disk 20. A hole 22 is defined at a center of the groove 21, and an inclined indentation 23 is formed in an outer side of the groove 21. A transparent top cover 30 further covers an upper portion of the ball disk 20, which prevents the ball 40 falling out from the ball disk 20. The transparent structural design of the top cover 30 and the ball disk 20 enables an operator to see the ball 40 for the purpose of controlling rolling of the ball 40.
Referring to
It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
