The side plates 12 and the connecting bar 22 are inserted with two fasteners 23, e.g. screws, such that the supports are fixedly coupled with the frame 10 and the transverse bars 21 steadily stand on the ground. Additionally, the transverse bar 21 has a top side provided with two U-shaped hinged portions 211.
Each of the [0020] armrests 30, which are inverted U-shaped, includes two long rods 31 having bottoms respectively pivoted to the two hinged portions 211 and two elastic pieces (not shown) interconnected with the rods 31 and the hinged portions 211. The two long rods 31 are coupled with an inverted U-shaped handlebar 32 at free ends thereof and the handlebar 32 is installed with a soft pad thereon and is adjustable to move up and down for a user holding the armrests 30 in different height. The armrest 30 lies against a retaining portion of the hinged portion 211 so as to be pivoted toward one direction between a first position, in which the armrest 30 is positioned upright, and a second position, in which the armrest 30 is positioned slantingly. Additionally, the elastic pieces (not shown) can bring the armrest 30 back to the first position.
The [0021] elastic member 40 having high elastic coefficient includes a body 41 having two fixing ends 42 and is disposed below the slots 111. The fixing ends 42 are locked by screws on a bottom side of the top plate 11 and are located at two sides of the slot 111 such that the body 41 of the elastic members 40 stands across the slot 111.
Each of the sliding [0022] seats 50 is composed of a sliding member 51, a guiding post 52 having two screwed ends, and a footpad 53.
The sliding [0023] member 51, which is inverted U-shaped, includes a main plate 511 and two side plates 512 respectively vertically connected with two opposite sides of the main plate 511 and is mounted over the frame 10. The main plate 511 includes a through hole 513 for a top end of the guiding post 52 running through. The guiding post 52 has a bottom end running through a nut 54 and the slot 111 and locked with another nut 55. Two rollers 56 are respectively rotatably installed at the inner sides of the side plates 512 of sliding seats 50 and are respectively inserted in the rails 121. Accordingly, the sliding seats 50 are moved back and forth along the longitudinal axle of the frame 10. Additionally, when the guiding post 52 is moved along with the sliding seats 50, the body 41 of the elastic member 40 is pulled by the guiding post 52 to be extended and transformed.
