(a) Field of the Invention
The present invention is related to a fitness equipment, and more particularly, to an improved structure of a treadmill that simulates treading motion for its user to achieve treading and twisting exercise purposes at the same time.
(b) Description of the Prior Art
People today often use excuses such as poor weather, or tight schedule to lead a life with little or even no sports at all, and recognize the importance of keeping a proper amount of sports when they find their immunity is deteriorating and symptoms of chronic diseases. Even so, they are reluctant to spare certain time each day to work out at a specific site or purchase fitness equipment to work out in leisure time.
To cope with the particular needs of the modern people who needs proper amount of workout while leading a busy life, fitness equipment simulating its best the outdoor workout patterns and allowing easy operation have been developed such as the one illustrated in
However, the treadmill of the prior art gets too monotonous to encourage continuous use for its user. As a result, the fitness equipment winds up in storage room for good.
The primary purpose of the present invention is to provide a twisting treadmill of fitness equipment to allow the user to achieve the purpose of staying fit by twisting and treading at the same time. To achieve the purpose, the present invention is related to rhythmic rotation equipment comprised of a treading unit, a turning member, and a transmission unit. The treading unit reciprocally ups and down; the turning member supports the treading unit and engages in reciprocal rotation; and the transmission connects the motions between the treading unit and the turning member.
Referring to FIGS. 2(A), 2(B), 3, and 4, a preferred embodiment of the present invention includes a mechanical construction with a base 10 as the primary member, a treading unit 20, a turning member 30, and a transmission unit. The treading unit 20 for being subject to the force applied by both feet of the user to proceed vertical motion pattern by simulating the stepping and pacing movement up and down. Meanwhile, a rhythmic rotation device is comprised of the treading unit 20, the turning member 30 and the transmission unit 40. As the rhythmic rotation device is operating and both feet of the user are stepping onto the treading unit 20 to have vertical motions, the turning member 30 and the treading unit 20 are engaging in reciprocal rotation for the user to achieve fitness results of twisting and treading at the same time.
Within the rhythmic rotation device, the treading unit 20 serves as an active mechanism to provide vertical motions; the turning member 30 supports the treading unit 20 to become a passive member; and the transmission unit 40 converts kinetics from the treading unit 20 into that of a connection mechanism to drive the transmission 40 to engage in lateral rotation to secure the connected motions between the treading unit 20 and the turning member 30.
In the preferred embodiment, the turning member 30 is comprised of a turning table axially pivoted to the base 10. A pair of parallel connection rods 23 to relatively engage in vertical oscillation is axially pivoted to the peripheral of the axis of the turning member 30. Two pedals 21 are respectively provided at the distal ends of both parallel connection rods 23. Through the connection of the pair of the connection rods 23, the motion from the treading unit 20 when subject to the force applied by both feet of the user on both pedals 21 produces the motive results of alternatively vertical motion between two pedals 21 as illustrated in
In practice, the transmission unit 40 as illustrated in FIGS. 2(A), 2(B), 3, 4, and 5, is comprised of a segment gear 41 fixed to the axis at the middle of the pair of parallel connection rods 23, and a conical gear 42 fixed to the base 10. Wherein, the center of the conical gear 42 is where a vertical shaft 31 of the turning member 30 is provided. Both of the conical gear 42 and the segment gear 41 are engaged to each other. When both parallel connection rods 23 relatively oscillate up and down, the segment gear 41 laterally swings along with the axis and is forced to reciprocally roll along the surface of the teeth of the conical gear 42 since the conical gear 42 is dead thus to drive the turning member 30 and the treading unit 20 to engage in reciprocal movement.
As illustrated in
Furthermore, as illustrate din
The prevent invention provides an improvement structure of a twisting treadmill, and the application for a utility patent is duly filed accordingly. However, it is to be noted that that the preferred embodiments disclosed in the specification and the accompanying drawings are not limiting the present invention; and that any construction, installation, or characteristics that is same or similar to that of the present invention should fall within the scope of the purposes and claims of the present invention.
