Abstract
A built-up spinning top is formed from a plurality of flat pieces, which are detachably connected to a flat board before being used to build up the top. The built-up spinning top mainly includes an elongate central shaft formed from two axially intersected shaft members to have a cross-shaped cross section, and a set of differently shaped and sized disc members sequentially mounted on the central shaft in a predetermined manner. The built-up spinning top may be spun with fingers or with the help of an ejecting platform and a push member. In the latter case, the disc members include two gear members to mesh with a toothed edge of a sliding way on the ejecting platform, so that the spinning top is rotated along the sliding way to finally eject therefrom to spin on a plane.
Claims7
A built-up spinning top system comprising a top including:
- (a) a central shaft including at least first and second axially extended shaft members, said first and second shaft members being engaged one with the other in crossed manner to collectively define for said central shaft a crossed sectional contour, said central shaft having a bottom spinning tip portion defined thereon;
- and,
- (b) a plurality of disc members coaxially disposed engaging said central shaft, said disc members including at least one large disc member and at least a first small disc member each having a cross-shaped opening receiving said central shaft therethrough;
- said shaft and disc members prior to assembly of said built-up spinning top respectively forming detachably delineated parts of a substantially planar unitary structure.
