  • FIG. 2 is a side view of the toy of FIG. 1; and
  • FIG. 3 shows an embodiment of the movement of the toy of FIG. 1 when it is being manipulated by a player.
  • DETAILED DESCRIPTION
  • Referring to FIG. 1, there is illustrated an embodiment of a toy 100 comprising a body 110 supported by a wheel arrangement 130 arranged to rotate about a rotating shaft 120 disposed at one end of the body 110, wherein the body 110 includes a ballast member 140 disposed adjacent to the rotating shaft 120 so as to allow the body 110 to incline about the rotating shaft 120 when the toy 100 is at rest.
  • As shown in FIG. 1, the toy 100 comprises a body 110, a rotating shaft 120, a wheel arrangement 130 and a ballast member 140. In the present embodiment, the body 110 is of an elongated cylindrical form. However, in some other embodiments, the body may resemble other shapes, configurations and forms without deviating from the scope of the present invention.
  • A rotating shaft 120 extending through the body 110 is provided in a lower portion of the body 110. Preferably, the wheel arrangement 130 is arranged to be connected to the shaft 120 so as to support the body 110 in an upright position, and to allow movement of the toy 100 along a surface when a force is applied to the toy by a player. In one embodiment, the wheel arrangement 130 of the present invention includes a plurality of wheels disposed on two sides of the cylindrical body 110. In the embodiment of FIG. 1, the wheel arrangement 130 includes two cylindrical wheels, each disposed on one side of the body 110. Alternatively, in other embodiments, the wheel arrangement 130 may include any number of wheels, and the wheels may resemble other shapes, configurations and forms without deviating from the scope of the present invention.
  • In the present embodiment, the wheels of the wheel arrangement 130 are rotatable about the rotating shaft 120 relative to the body 110 when a force is applied to the toy 100 such that the wheels roll along a surface to facilitate movement of the toy 100. Preferably in this embodiment, the body 110 is also rotatable about the rotating shaft 120 relative to the wheel arrangement 130 when a force is applied or transmitted to the body 110 such that the body 110 may pivot about the rotating shaft 120.
  • Preferably, the wheels of the wheel arrangement 130 in the present embodiment are fixedly connected with the rotating shaft 120 and the body 110 is rotatably mounted to the rotating shaft 120. This arrangement allows the wheels of the wheel arrangement 130 to rotate together with the rotating shaft 120, and the body 110 to pivot about the rotating shaft 120 that rotates with the wheels.
  • In an alternative embodiment, the body 110 is fixedly connected with the rotating shaft 120 and the wheels of the wheel arrangement 130 are rotatably mounted to the rotating shaft 120. In other words, in this arrangement the wheels of the wheel arrangement 130 do not rotate together with the rotating shaft 120, and the body 110 pivots about the rotating shaft 120 by rotating together with the rotating shaft 120.
  • Preferably, a ballast member 140 is arranged at the bottom portion of the body adjacent to the rotating shaft 120 to facilitate the movement of the toy 100 along a surface. In the present embodiment, the ballast member 140 is disposed below the rotating shaft 120. As shown in the side view of FIG. 2, the upper surface of the ballast member 140 is arranged to be substantially horizontal or flat when the toy 100 is at rest. Preferably, the ballast member 140 of the present invention is a weighted material that is generally heavier than the remaining of the body 110 of the toy 100. In the present embodiment, the ballast member 140 is an asymmetric counterweight as shown in FIG. 2. In one embodiment, the ballast member 140 is made of wood, plastic, metal or any combination of materials thereof.
  • FIG. 2 shows a side view of the toy 100 at rest/at an equilibrium position. As shown in FIG. 2, the body 110 is arranged to be “inclined” by tilting towards the heavier side of the asymmetric counterweight 140 when the toy 100 is at rest/at the equilibrium condition. In the present embodiment, the asymmetric counterweight 140 is arranged such that the body 110 is tilted backward with respect to the travelling direction of the toy 100 when the toy 100 is at rest. However, in one embodiment, the asymmetric counterweight 140 may be arranged such that the body 110 is tilted forward with respect to the travelling direction of the toy 100 when the toy 100 is at rest. In either case, the longitudinal axis A-A of the body 110 is at an angle α with vertical axis O-O perpendicular to the surface of which the toy 100 is resting on. Preferably, the angle α is 20 to 40 degrees. The arrangement of the counterweight 140 in the body 110 facilitates the linear movement of the toy 100 along the surface when a force is applied to the body 110.
  • FIG. 3 shows the movement of the toy 100 when it is being manipulated by a player. As shown in FIG. 3, the upper portion of the body 110 inclines backwards with respect to the travelling direction with angle α when the toy 100 is at rest. When a force is applied by a player's fingers or hand to press or push the upper portion of the body 110, the upper portion of the body 110 rotates further backwards (more than the inclination of the toy 100 at rest) about the rotating shaft 120 with respect to the travelling direction. As a result, the backward rotation of the upper portion of the body 110 propels the toy 100 forward such that the toy 100 moves away from the player's fingers or hand as indicated by an arrow in FIG. 3. Also, as the upper portion of the body 110 rotates further backwards, the lower portion of the body 110 with the ballast member 140 rotates forward about the rotating shaft 120 with respect to the travelling direction.
  • As a result of the forward rotation of the lower portion of the body 110 with the ballast member 140 about the rotating shaft 120, and the backward rotation of the upper portion of the body 110 about the rotating shaft 120, the center of gravity of the body 110 with the ballast member 140 and the center of the rotating shaft 120 do not lie on the same vertical plane. Particularly, during the initial movement of the toy 100 with the upper portion of the body 110 swinging backward with respect to the travelling direction, the center of gravity of the body 110 with the ballast member 140 is disposed forward to the center of the rotating shaft 120 with respect to the travelling direction. Due to the forward displacement of the center of gravity of the body 110 with the ballast member 140, the torque provided by the center of gravity of the body 110 with the ballast member 140 will act on the toy 100 such that the upper portion of the body 110 reverses its rotation and rotates forward about the rotating shaft 120 with respect to the travelling direction whereas the lower portion of the body 110 also reverses it direction of rotation and rotates backward about the rotating shaft 120 with respect to the travelling direction. The resultant effect is that the body 110 of the toy 100 will oscillate to and fro about the rotating shaft 120 with successive forward and backward inclination as the toy travels in the forward direction. Preferably, the amplitude of the oscillation of the body 110 gradually decreases due to damping and the toy 100 eventually stops due to the friction between the wheels and the surface.
  • In the present embodiment, the center of gravity of the body 110 with the ballast member 140 is disposed below the rotating shaft 120 so as to ensure the body 110 will not topple during the movement of the toy 100 whilst ensuring the movement of the toy 100 can be triggered smoothly. In other words, the body 110 is operable to oscillate to and fro about the rotating shaft 120 and returns to its initial position (with a backward inclination of angle α without toppling during movement of the toy 100 after a force has been applied to trigger the movement the toy 100. In the present embodiment, the positioning of the ballast member 140 below the rotating shaft 120 when the toy 100 is at rest is particularly advantageous in that it can ensure that the center of gravity of the body 110 with the ballast member 140 is arranged below the rotating shaft 120 such that the self-balancing of the toy 100 can be drastically improved.
  • The embodiment of the toy in the present invention is advantageous in that a player can experience more enjoyment with the toy by simply pressing onto or giving a slight push to the upper portion of the body so as to trigger the movement of the toy. Also as the toy moves, the body of the toy oscillates to and fro. This may enhance visual interest of the toy to the players. Other advantages of the toy of the present invention with regard to structure, function, and manufacturing ease and cost will be apparent to a person skilled in the art after referring to the above description.
  • It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
  • Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
