Abstract: The present invention relates to a mobile for an infant, and more particular, to a mobile available of both sides, comprising a mobile body including a lower face formed as a black and white face (11) and an upper face formed as a color face (12); rings (20, 20?) formed, respectively, on the centers of the black and white face (11) and the color face (12); and a rim (30) formed suturingly on an outer peripheral surface of the mobile body (10).

Abstract: The invention is an improved yo-yo that has a rotatable, outwardly-facing roller on each of its two sides. Each roller has an outwardly-facing opening that is sized and shaped to facilitate a non-slip engagement between a finger and the roller. The opening also provides access to an O-ring that functions to secure the roller to the yo-yo.

Abstract: Spin message toy with a rigid rectangular block member, a right side string loop and a left side string loop. The block member has a broad front surface and broad rear surface. The string loops are attached to the left and right sides of the block so that it is capable of spinning on a horizontal plane when a user pulls in opposing directions on the string loops that have been twisted by the user just before operation. The front surface has a first partial message printed upon it. The rear surface has a second partial message printed upon it. The first and second partial messages form the illusion of a complete message when the rectangular block member is spun by the user.

Abstract: A toy top includes a body portion including a circumferential slot thereabout adapted to receive wound therein a portion of a cord used to launch the top. The top spins about a spin axis and is configured so that the slot is at or adjacent the center of gravity of the top. The body portion includes an interior shaft portion extending within the body portion, and an exterior shaft portion extending from the body portion. The cord is attached to a collar attached to the top of the external shaft portion. The cord is rotatably attached relative to the body portion. A weapon may be attached to the body portion, and players may battle their tops using respective weapons.

Abstract: A device for amusing a cat or other pet is provided that has a housing having a top portion and a bottom portion, a motor disposed in the housing, a belt attached to the housing via an upper shaft and a lower shaft, a string having a first end attached to the belt and a second end extending freely from the belt, and means for activating the motor. In operation the motor rotates the belt causing the string to repeatedly fling outwardly from being hidden within the frame and amuse the cat. Methods for amusing a pet are also disclosed that comprise the steps of automating a string, whereby a free end of the string appears and disappears from view. These methods are preferably accomplished by attaching one end of the string to a rotating belt within a housing.

Abstract: The present invention relates to a self-generating wrist ball which includes a ball-shaped housing, a revolution ring, a flywheel and a generating and lighting mini-module. The ball-shaped housing has a plurality of protruding arched pieces to enhance the light-concentrating effect and to increase the stability when the fingers hold the wrist ball. The generating and lighting mini-module includes at least two rotor aggregates within flywheel and at least two stator aggregates corresponding to said rotor aggregates being fixed on the revolution ring. The wrist ball is self-generating in operational state by means of the impulse excitation created at the rotational moment of the wrist ball. In addition, the effect of magnetic field line can be enhanced by means of magnets and magnetic metal plates of the rotor aggregates and the stator aggregates. Furthermore, the same magnetic poles of both magnets are arranged in opposite way to prevent the flywheel from interference in rotation.

Abstract: A metal yo-yo embodies a construction in which each of the halves of the yo-yo body is formed from a disc and a hub that are made separately and secured to each other in an integral structure. The discs can be die cut from sheet material and may be deformed about the peripheral margin to define a dished configuration. The hub is inserted into the center hole of the disc and the two are assembled together in a swaging operation that constricts the metal of the disc about a portion of the hub. A pair of such yo-yo halves are connected together by an axle assembly that includes a bearing to facilitate extended spin time for the yo-yo. The yo-yo construction and method of fabrication provides substantial economies in the manufacture of metal yo-yos. In another aspect of the disclosure, the inwardly facing surfaces of the yo-yo halves may be formed to define an annular recess that cooperates with the yo-yo string in a manner that affects retrieval of the yo-yo.

Abstract: A yo-yo having a multi-image lenticular instruction system. The system is incorporated into at least one of the yo-yo's side members via a side cap that is secured to the side member and is readily visible. The instruction system functions by displaying sequential images showing how to perform a predetermined yo-yo trick. A user can manually manipulate the yo-yo to display the images in either a forward or reverse order and at any speed the user desires. By watching the images, the user can easily see how to perform the displayed yo-yo trick.

Abstract: A rotary drive mechanism for toys, kinetic sculptures, and the like, employs a pawl and ratchet mechanism to transmit driving torque between a driving wheel and a driven inertia wheel. The driving wheel may itself be driven by means of a drive string that may frictionally engage a circular drive surface to permit the driving wheel to be rotated independently with limited slippage between the string and the drive surface. A fixed and uniform amount of energy can be imparted to the driving wheel and the driven wheel through a spring that is connected to the drive string and preloaded by a predetermined amount. A second inertia wheel can be mounted coaxially of the one inertia wheel and both wheels may operate with random motion through an interference coupling. The pawl and ratchet mechanism in one embodiment forms an escapement to provide intermittent drive to the wheels. The inertia wheel is rotationally unbalanced with a weight offset from the axis of rotation.
