Abstract
A treadmill comprised of two pedal assemblies for the user to tread alternatively with both feet up and down; each pedal assembly having at its base pivoted with a front and a rear dancer; the tails of both dancers being respectively pivoted to the front and the rear ends of a pedal; a linking member being disposed at where between both pedal assemblies; and both pedals normally maintaining horizontal status as both pedal assemblies alternatively move up and down to allow user to easily maintain balance and better mobility for both feet.
Description
- (a) Field of the Invention
- The present invention is related to fitness equipment, and more particularly to a treadmill that allows simple structure, easy maintenance of balance, and better mobility for both feet of its user.
- (b) Description of the Prior Art
- Whereas most fitness equipments generally available in the market simulate the motion patterns of outdoor sports, the user of the fitness equipment is able to work out within a confined room while achieving the equivalent fitness results in the open air. For example, a treadmill allows it user to alternatively tread on both pedals in simulating the walking pattern to achieve the purposes of sports and staying fit.
- The treadmill of the prior art is essentially comprised of two pedals having their front ends pivoted to a base and both pedals are connected to a hydraulic cylinder with a rope or a steel cable to alternatively move both pedals up and done by taking advantage of the damping from the hydraulic cylinder to maintain coordination between the motion of both pedals. Meanwhile, the hydraulic cylinder provides proper resistance to the motion of both pedals to demand more workout load from the user.
- However, the production cost of the prior art is higher and the construction of having the hydraulic cylinder to regulate the treading force is more complicated. The higher cost directly affects the market competition strength of the prior art. In practical use, as the pedal rises higher, the angle of forward inclination gets bigger to put the user to expose to sports injuries since the mobility of his both feet are restricted while having difficulties to keep balanced and failing to relax for managing to stay balanced.
- The primary purpose of the present invention is to provide a treadmill that allows easier maintenance of balance and better mobility for both feet of its user. To achieve the purpose, the present invention is essentially comprised of two pedal assemblies with each having at the base pivoted to a front and a rear dancers and the tail of each dancer being respectively pivoted to the front and the rear of a pedal. A linking member pivoted to a shaft is disposed at where between two pedal assemblies while two connection rods being respectively linked to where between the rear dancers and the linking member of both pedal assemblies.
- Accordingly, two rear dancers from both pedal assemblies that reciprocally swing relatively to each other to create the treading pattern due to the traction from both connection rods and the linking member. Both pedals in the process of the motion by both pedal assemblies are normally maintaining in horizontal status for the user to easily keep balanced and have better mobility for both feet.
- Another purpose of the present invention is to provide a treadmill that the force exerted on both pedal assemblies can be regulated. To achieve the purpose, an upper clamping plate and a lower clamping plate are respectively pivoted to the shaft at where above and below the linking member. A first bolt is installed to both clamping plates at where they are in relation to another end of the shaft. A resistance plate disposed to the linking member extends to the peripheral of the first bolt, and the resistance plate slides between both clamping plates as the linking member swings laterally in conjunction with the vertical motion executed by both pedal assemblies. Accordingly, by adjusting the spacing between the first bolt and both clamping plates, the sliding capability of the resistance plate is changed, thus to achieve the purpose of regulating the force applied by the user onto both pedal assemblies.

FIG. 1 is a perspective view of a preferred embodiment of the present invention. -
FIG. 2 is a bird's eye view of the preferred embodiment of the present invention. -
FIG. 3 is a schematic view showing the motion of the preferred embodiment of the present invention. -
FIG. 4 is a sectional view of a construction of peripheral elements to the linking members of the preferred embodiment of the present invention. -
FIG. 5 is a schematic view showing that the preferred embodiment is collapsed for storage. - Referring to
FIGS. 1 and 2 , a preferred embodiment for a treadmill of the present invention is essentially comprised of abase 10, and twopedal assemblies 20 adapted to thebase 10 for the user to tread on with both feet. Each pedal assembly includes apedal 23 and both pedals are laid out at a given included angle for the treading pattern to be even more close to that of the practical exercise. - Wherein, each
pedal assembly 20 has at thebase 10 pivoted with afront dancer 21 and arear dancer 22. Each tail of the front and therear dancers pedal 23. A linkingmember 30 pivoted to ashaft 41 is disposed at where between bothpedal assemblies 20. Twoconnection rods 32 are respectively coupled to where between both rear dancers and the linkingmember 30. Accordingly, while the user has both feet to tread on bothpedals 23, both pedal assemblies 20 alternatively move up and down through bothconnection rods 32 and traction from the linkingmember 30 to produce the fitness purpose by treading as illustrated inFIG. 3 . - In the process of the motion executed by both
pedal assemblies 20, bothpedals 23 normally maintain in horizontal status due to the linkage for motion by both front andrear dancers pedal 23 to alleviate the impact force produced as the pedal presses down. - Now referring to
FIG. 4 , anupper clamping plate 42 and alower clamping plate 43 are pivoted to the shaft respectively at where above and below the linkingmember 30. Afirst bolt 51 inserts through both of the upper and thelower clamping plates shaft 41, and aresistance 31 disposed to the linkingmember 30 extends to the peripheral of thefirst bolt 51. Theresistance plate 31 slides between both of the upper and thelower clamping plates member 30 swings laterally in conjunction with the vertical movement executed by bothpedal assemblies 20. Therefore, the spacing between both of the upper and thelower clamping plates first bolt 51 so to change the sliding capability of thefirst bolt 51, thus to regulate the force applied by the user onto bothpedals 23. Afriction plate 55 that contacts theresistance plate 31 is provided between both of the upper and thelower clamping plates resilient pad 56 made of rubber or similar material is disposed at where between thefirst bolt 51 and theupper clamping plate 42 to define a proper friction against theresistance plate 31 by both of thefriction plate 55 and theresilient pad 56. - Furthermore, a
base plate 55 is disposed to the base at where at the rear end of theshaft 41 and asecond bolt 52 is laterally mounted to thebase plate 55. The tail of thesecond bolt 52 and the lower end of theshaft 41 push against each other so to change the relative positions of the linkingmember 30 and both pedal assemblies 20 by changing the angle of theshaft 41 through thesecond bolt 52, and thus to regulate the height of thepedal 23. Ahexagonal nut 53 is each mounted to the top of thefirst bolt 51 and that of thesecond bolt 52 to allow the user to turn both of the first and thesecond bolts pedals 23 without relying upon any hand tool. - The prevent invention provides an improved construction of a 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.
