DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings. and initially to FIGS. 1-4, a treadmill apparatus in accordance with the present invention comprises a base 10 including one or more posts 11 extended upward therefrom, such as extended upward from the front portion thereof, and including one or more handles 12 provided on top of the posts 11, and including a shaft 13 rotatably provided on the middle or the rear portion thereof. A wheel 14 or the like is secured to the shaft 13 and rotated in concert with the shaft 13. A motor 15 is disposed on the base 10 and coupled to the wheel 14 and/or the shaft 13 with a transmission device 16, such as a pulley-and-belt or a sprocket-and-chain transmission device 16, such that the shaft 13 may be rotated and driven by the motor 15.

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 FIGS. 2-10, the treadmill apparatus in accordance with the present invention further comprises a coupling device for coupling the treadmills together and for allowing the treadmills to be conducted with a stepping exercise. The coupling device includes an arm 40 having an orifice 41 formed in the middle portion thereof (FIGS. 5, 7, 8), for receiving a pivot axle 18 which may rotatably or pivotally securing the arm 40 to the base 10, and for allowing the ends of the arm 40 to be moved; up and down and to be disposed below the treadmills 20, 30 respectively. The ends of the arm 40 each includes a frame 42 provided therein for supporting a rod 43 therein which is about parallel to the longitudinal direction of the base 10 and of the treadmills 20, 30 and which is perpendicular to the arm 40.

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 FIGS. 7 and 8, when one of the treadmills 20 is depressed downward by the user (FIG. 8), the other treadmill 30 will be moved upward by the arm 40. On the contrary, when the treadmill 30 is depressed downward by the user (FIG. 7), the other treadmill 20 will be moved upward by the arm 40, such that the treadmills 20, 30 may be actuated or operated as the stepping exercisers.

Referring next to FIGS. 1 and 11, the treadmills 20, 30 each includes one or more stops 31 attached to the side portions of the platforms 21 and engaged with the treads 23, for stably retaining the treads 23 within the platforms 21 respectively, and for preventing the treads 23 from being disengaged from the platforms 21 respectively.

Referring next to FIGS. 12 and 13, the treadmills 20, 30 each further includes an extension 33 extended downward therefrom, such as extended downward from the platform 21 thereof. The extensions 33 each includes a notch 34 formed therein. A retaining or locking or latching device 37 is pivotally coupled to or secured to the base 10 with a bracket 38 or the like, and includes a lock member or a latch 39 for engaging into the notches 34 of the extensions 33 and for locking the treadmills 20, 30 together, such that the treadmills 20, 30 may not be moved up and down relative to each other and may be used for conducting the treadmill exercises only.

Referring next to FIGS. 14-16, illustrated is another embodiment of the coupling device which also, includes an arm 70 rotatably secured to the base 10 with a pivot axle 71. However, the ends of the arm 70 may be moved forward and rearward, instead of being moved up and down as that shown in FIGS. 2-10. Two pairs of bolts 72, 73 are pivotally secured to the ends of the arm 70 and to the bars 24 with a joint, such as a universal joint 24 respectively. A longitudinal nut 74 is threaded onto the pair of bolts 72, 73 for moving or adjusting the bolts 72, 73 toward or away from each other and for adjusting the bars 24 relative to the arm 70, according to the configuration or the location of the treadmills 20, 30.

Accordingly, the treadmill apparatus in accordance with the present invention includes dual treads for conducting both jogging and stepping exercises.

Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
