Abstract: A kick scooter includes a deck, an upright tube, and a folding mechanism. The upright tube is mounted by the folding mechanism to the deck. The folding mechanism includes a mounting case mounted on the deck and two connecting arms attached to the upright tube. The mounting case is pivotally mounted to a rocking arm that is provided with a position-restoring preloading force and has a free end to which a moving bar is attached. The two connecting arms are respectively formed with arc guide slots opposite to each other and centered at a pivotal joint to receive a moving bar of the rocking arm to extend therethrough for being guided thereby to move. Each arc guide slot has two ends respectively formed with a folding positioning notch and an expanding positioning notch for selectively positioning the moving bar therein as being biased by the position-restoring preloading force.

Abstract: A scooter (5) includes a head tube (50); a riser tube (51) freely and rotatably pivoted with the head tube (50), the upper end of the riser tube being provided with a handle (511); a preceding runner (52) provided at the lower end of the riser tube (51); a left carrier (53) and a right carrier (53) both connected to the head tube (50); a left back runner (54) and a right back runner (54) provided at the left carrier (53) and the right carrier (53) respectively, which support the scooter (5) alone with the preceding runner (52); the front end of each carrier (53) is provided with a cantilever (533) respectively. The left cantilever (533) and the right cantilever (533) are both provided at the head tube (50) in a suspending form of swinging back and forth freely. Provided between the left cantilever, the right cantilever (533) and the head tube (50) is a holding means (55) enabling the left carrier and the right carrier to perform back and forth alternate swing and displacement action.

Abstract: A stepping exerciser includes a bracket, a rack, a pair of pedal holders rotatably mounted to an upper portion of the bracket, a pair of pedal holders rotatably mounted to an upper portion of the bracket, a pair of pedals, a beam pivoting the bracket to an upper portion of the rack, a pair of connecting levers respectively rotatably connected between the pedals and the rack, a pair of wheels and a pair of flexible pulling members. The wheels are rotatably installed on the rack. Each flexible pulling member is pivoted at one end thereof to the beam and at the other end thereof to a lower portion of the pedal holders. The flexible pulling members installed between the beam and the pedal holders enhance movement resistance to the pedals, for efficiently exercising multiple parts of a user.
