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.

Abstract: A locking mechanism adapted for locking a bicycle fork has a locking sheath and an adjusting rod. The locking sheath is adapted to be positioned within the bicycle fork. The adjusting rod is adapted to slidably engage the locking sheath. The adjusting rod is adapted to rotate with respect to the locking sheath between a locked configuration and an unlocked configuration. A first interlocking element of the adjusting rod lockingly engages with a second interlocking element of the locking sheath in the locked configuration, and the first and second interlocking elements are disengaged from each other when the adjusting rod is rotated to the unlocked configuration.

Abstract: An abdominal exercise machine includes a U-shaped base, a head member, two first mounting members, and two handles. The base includes a main portion, and two arm portions extending from opposite ends of the main portion. The head member is mounted to main portion of the base. The first mounting members are mounted to corresponding arm portions of the base. A plurality of locating portions is formed on each of the first mounting members. Each of the mounting members has an arc-shaped edge. The handles are rotatably mounted to the corresponding mounting members. The handles are selectively mounted to the location portions of the corresponding first mounting members.

The flexible pulling sheets installed between the beam and the pedal holders enhance movement resistance to the pedals, for efficiently exercising multiple parts of a user.

Abstract: A joint mechanism for use in a rod for bearing at least a portion of a user's weight and a corresponding flexible tip for contacting a substantially horizontal surface. The joint mechanism includes a spring mechanism, a first bushing, and a second bushing. The spring member has opposed first and second ends. The first bushing is adapted for positioning in a hole in an end of the rod and has a cavity adapted to receive the first end of the spring member. The second bushing is adapted for positioning in a hole in the flexible tip and has a cavity adapted to receive the second end of the spring member.

Abstract: An exercise machine has a swing structure mounted on a frame for both swinging and lateral movement. The frame has a top portion. A ring is pivotally connected to the top portion of the frame. The swing structure is rotatably coupled to the ring and adapted for engaging the feet of a user. A seat is attached to an upper surface of the swing structure.
