Latest Nautilus, Inc. Patents:
The present application is a broadening reissue application of and claiming priority to U.S. Pat. No. 6,461,279 titled “Treadmill Having Dual Treads For Stepping Exercises” issued on Oct. 8, 2002, application Ser. No. 09/912,664, filed Jul. 25, 2001, which is hereby incorporated by reference herein.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a treadmill apparatus, and more particularly to a treadmill apparatus having dual treads for conducting both jogging and stepping exercises.
2. Description of the Prior Art
U.S. Pat. No. 5,336,146 to Piaget et al. discloses one of the typical treadmills including dual treads that may be alternatively pivot up and down as a user walks thereon. However, Piaget et al. fail to disclose a coupling device for coupling the two treads together, due to the continuous treads.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional treadmills.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a treadmill apparatus including dual treads for conducting both jogging and stepping exercises.
In accordance with one aspect of the invention, there is provided a treadmill apparatus comprising a base including a first end, and including a second end having a shaft provided thereon, a pair of treadmills disposed above the base, and each including a platform having a roller provided on a first end thereof and attached to the shaft, and each including a tread supported around the platform, means for driving the shaft to actuate the treads, an arm including a middle portion pivotally supported on the base with a pivot axle, and including two ends located below the treadmills respectively, and means for coupling the ends of the arm to the treadmills to elevate a first of the treadmills when a second of the treadmills is lowered, and to elevate the second treadmill when the first treadmill is lowered. The treadmills may thus be moved up and down relative to each other by the arm, and may thus be actuated as a stepping exerciser.
The treadmills each includes a bar attached to the platform thereof and extended downward from the platform for coupling to the ends of the arm respectively.
The ends of the arm each includes a rod provided therein and perpendicular to the arm, and a column pivotally secured to the respective rod, the treadmills each includes a bar attached to the platform thereof and coupled to the column respectively.
A device may further be provided for locking the treadmills together.
A device is further provided for retaining the treads on the platforms respectively and for preventing the treads from being disengaged from the platforms.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
Referring to the drawings. and initially to
A pair of treadmills 20, 30 are identical in construction, and each preferably includes a rigid treadmill platform 21 having a front end and a rear end, rollers 22 rotatably mounted at each of the front end and the rear end of the platform 21, and a continuous tread 23 extended around the platform 21 and rotatably supported on or around the rollers 22. The rollers 22 may be secured on the shaft 13, such that the rollers 22 and thus the treads 23 may be rotated or driven by the motor 15, and such that the treadmills 20 pivotally mounted on the base 10 in side-by-side adjacent relation by the shaft 13. The rollers 22 may also be separately coupled or secured on the shaft 13 by gearing transmission or the like, for allowing the treads 23 of the two treadmills 20 to be driven separately by the motor 15. Two spring-return hydraulic cylinders or actuators 17 are coupled between the posts 11 and the treadmills 20 respectively for supporting the treadmills 20, such as the front ends of the treadmills 20 in an inclined position. The actuators 17, and/or the construction of the treadmills 20 is considered to be conventional in the art, and therefore no further description is thought to be necessary.
As shown in
Two columns 47 have the lower portions pivotally or rotatably secured onto the respective rods 43 with such as a universal joint or the like. The treadmills 20 each includes a bar 24 secured to the middle portion of the platform 21 thereof and extended downward therefrom and having a lower end pivotally or rotatably secured to the upper end of the column 47 with a rod 27 and a joint 28, such as a universal joint or the like. The treadmills 20 thus may be coupled to the ends of the arm 40 with the bars 24, the rods 27, the joints 28, the columns 47, the pivot rods 43, and the frames 42.
In operation, as shown in
