The present invention relates to a top generating a clear collision sound when the top collides with another top so as to make playing with a top more exciting, and having an improved fastening structure for a metal wheel on the top so as to allow the metal wheel to sufficiently vibrate when the top collides.

A four bar apparatus and method are provided for lifting, lowering, providing exercise and facilitating self-propelled transit. The apparatus includes an actuator and interconnected four-bar lifting mechanism, which includes a crank, a coupler, a rocker, and a frame. Each of the crank, coupler, rocker and frame are rotatably interconnected, and operation of the actuator moves a lift point of the coupler, with the lift point connectable to a vest-type garment or belt worn by a user of the apparatus, with the lift point following a J shape path or an S shape path to lift the user from a shoulder or hip area, respectively.

A toy top includes a body and a shaft unit. The body includes rotating components which are attached to be rotatable relative to each other. At least two of the rotating components include respective contact portions which come in contact with each other to regulate a rotation range between the two rotating components. The contact portions are configured such that contact between the contact portions gradually become loose as the contact portions repeatedly come in contact with each other due to relative rotation of the two rotating components, and capability of regulating rotation is eventually lost so that the rotation range is expanded.

A toy top includes a shaft portion, a body and an attacking member. The body is rotatable relative to the shaft portion in response to an impact applied to the body. The attacking member is movably connected to the body to move in a predetermined direction relative to the body between first and second positions. In the second position, the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion.

A spinning top includes a body, a shaft part, a first guide groove, and a weight member. The shaft part is arranged to be in contact with a floor when spinning, and is detachably attached to the body. The first guide groove is configured on the shaft part around a rotating shaft thereof and is extended from a first point to a second point, where a first distance between a center of the shaft part and the first point is larger than a second distance between the center and the second point. The weight member is configured inside the first guide groove and is configured to be moved in response to a rotation speed of the shaft part.

A spinning top toy includes a shaft part including a rotating shaft arranged to be in contact with a floor when spinning and a body being configured on the shaft part. The body includes a guide groove extending in a direction from the rotating shaft to an outer periphery of the body, the guide groove including a step, and a first spherical-shaped weight member being stored and movable in the guide groove.

A spinning top toy arranged to spin around an axis thereof includes a main part including a body main part, a shaft part detachably attached to the main part, where the shaft part being configured to be in contact with a floor when spinning, and first and second overhanging portions configured on the main part. The first overhanging portion is configured to be non-rotatable with respect to the body main part. The second overhanging portion is configured to be rotatable around the axis with respect to the body main part, and is configured to be engageable with the body main part at a first rotation position and a second rotation position being different from the first rotation position.
