Reference will now be made in detail to a preferred embodiment of the toy ball disclosed in the present application, examples of which are also provided in the following description. Exemplary embodiments of the toy ball disclosed in the present application are described in detail, although it will be apparent to those skilled in the relevant art that some features that are not particularly important to an understanding of the toy ball may not be shown for the sake of clarity.
Furthermore, it should be understood that the toy ball disclosed in the present application is not limited to the precise embodiments described below and that various changes and modifications thereof may be effected by one skilled in the art without departing from the scope of the appended claims. For example, elements and/or features of different illustrative embodiments may be combined with each other and/or substituted for each other within the scope of this disclosure and appended claims.
Referring now to the drawings, in which like reference numerals represent like parts throughout the drawings, Figure 1 is an exploded view of a toy ball according to a first embodiment of the present application. The toy ball includes a stack of corolla-like units 1 and a connector 2 for holding the stack of corolla-like units 1 together. The corolla-like units 1 are made of an elastic material or any other soft and flexible material. For example, the corolla-like units 1 may be made of thermoplastic rubber, thermoplastic elastomer, thermoplastic polyurethane resin, poly-carbamate or silicone. The corolla-like units 1 may be manufactured by injection molding, die-cast molding or any other suitable kind of molding.
Figure 2 is a top view of the corolla-like unit 1 of the toy ball of the first embodiment. Each corolla-like unit 1 may include a central portion 10 and a plurality of fins or petal-like portions 11 extending radially outwards from the central portion 10. The central portions 10 may be formed with two through-holes 101 allowing the connector 2 to pass therethrough. The two through-holes 101 can be formed by aligning holes 101 formed on the central portions 10 of the corolla-like units 1 when they are in the initial stacked configuration.
In the present embodiment, each stack may have eight corolla-like units 1 although it is understood that the number may vary according to the size of the toy ball to be made. Also, it can be seen that each corolla-like unit 1 has twelve petal-like portions 11 though the number may vary depending on the shape of the petal-like units 11 and the size of the toy ball to be manufactured.
According to the illustrated embodiment, the connector 2 can be in the form of a self-locking cable tie. The self-locking cable tie may be made of plastic or other suitable material. A tail portion 21 of the self-locking cable tie 2 can be adapted to pass through the two through-holes 101 formed on the central portions 10 and through a locking head portion 22 of the auto-locking cable tie 2, as illustrated in Figure 1, thereby tying the stack of corolla-like units 1 together.
When the auto-locking cable tie is tightened, the central portions 10 can be squeezed together inwards. The squeezing force can bend the plurality of petal-like portions 11 outwards around the squeezed central portions 10 due to elasticity and turn the plurality of petal-like portions 11 from the stacked configuration to a substantially spherical configuration. In this spherical configuration, the plurality of petal-like portions 11 radiates outwards from a core defined by the squeezed central portions 10. The substantially petal-like portions 11 in the substantially spherical configuration form a toy ball that can be played in children's games such as a catch-and-throw ball game.
In the illustrated embodiment, each of the petal-like portions 11 may be in the form of a flat plate having its width increasing outwards from the central portion 10. Although it has been shown and described that each petal-like portion 11 is in the form of a plate, it is understood that each petal-like portion 11 may be in any other possible form such as an elongated strip, a filament or a curled filament, etc.
Figure 3 is an exploded view of the toy ball according to a second embodiment of the present application. In this embodiment, the toy ball may further include a plug-and-socket fastener having a plug or first member 30 and a socket or second member 31. The second member 31 may be formed with two apertures 311; and the first member 30 may be formed with two stems 301. The two stems 301 of the first member 30 can be inserted through another two through-holes 101 formed on the central portions 10 and into the two apertures 311 of the second member 31.
One of the first and second members 30, 31 may be formed with a compartment 302 for accommodating therein the head portion 22 of the auto-locking cable tie 2. The first and second members 30, 31 of the plug-and-socket fastener may be made of rubber or plastic or any other suitable material.

Figure 4 is a cross sectional view of the second member 31 of the plug-and-socket fastener of the second embodiment of the toy ball. The first and second members 30, 31 may be semi-spherical in shape as shown in the illustrated embodiments or in any other appropriate shape.
Figures 5 and 6 are top and perspective views of the corolla-like unit 11 of the second embodiment of the toy ball respectively. The corolla-like unit 11 of the second embodiment of the toy ball is similar to the corolla-like unit 11 of the first embodiment. The difference is that the central portion 10 of the corolla-like unit 11 of the second embodiment has four through-holes 101, whereas the central portion 10 of the corolla-like unit 11 of the first embodiment has two through-holes 101 only for the auto-locking cable tie 2 to pass therethrough.
Figures 7 and 8 are bottom and exploded views of a toy ball respectively according to a third embodiment of the present application. The toy ball in this third embodiment is similar to the toy ball in the second embodiment except that it does not have the auto-locking cable tie 2. In the third embodiment, the toy ball may include only the plug-and-socket fastener having the first member 30 and the second member 31. The second member 31 may be formed with four apertures 311 and the first member 30 may be formed with four stems 301. The four stems 301 of the first member 30 can be inserted through four through-holes 101 formed on the central portions 10 and into the four apertures 311 of the second member 31 respectively. The central portions 10 of the stack of corolla-like units 1 can be squeezed and held together by the first and second members 30, 31. Since the toy ball does not have an auto-locking cable tie, the first and second members 30, 31 are not formed with any compartment 302. Again, the four apertures 311 of the second member 31 and the four stems 301 of the first member 30 may be coupled together by press-fitting, glue bonding, heat melting or any other possible method.
Although it has been shown and described that the plug-and-socket fastener has two or four stems and apertures, it is appreciated that the plug-and-socket fastener may have one, three or more than four stems and apertures depending on the size of the toy ball to be manufactured.
