Abstract: A physical exercising apparatus, which includes a first transverse frame bar having a longitudinal center through hole, a second transverse frame bars, two wheels respectively mounted on the wheel holders for supporting the second transverse frame bar on the floor, and an elastic cord member inserted through the longitudinal center through hole on the first transverse frame bar and connected between the wheel holders for stretching by the user when the user holds the first transverse frame bar in place and moves the second transverse frame bar relative to the first transverse frame bar.

Abstract: A stepping exerciser including a base frame, an upper support, a stepping device, a front stem, a rear seat stem and a damper. When two pedal levers of the stepping device are alternately stepped up and down, the pushing arms under the pivot tubes of the pedal levers drive the linkages to alternately swing back and forth. At this time, the driving rods under two sides of the rotary discs are driven to rotate the rotary disc. Responsively, the handle bar connected with upper end of the front stem connected with the rotary disc are alternately swung left and right. Accordingly, the feet of a user alternately step on the pedals to a large extent and simultaneously, the waist and hands of the user correspondingly act to achieve an exercising effect.

Abstract: A stepping machine including a base frame having an upright stub tube and an upright shaft, the upright stub tube having two horizontal axles and two connecting plates respectively turned about the horizontal axles, an upright post revolvably mounted on the upright stub tube and having a transverse handlebar at the top, a pedal support revolvably mounted on the upright shaft and coupled to the upright support in a parallel relation, two pedals respectively turned about a respective horizontal axle on the pedal support, and two hydraulic cylinders bilaterally connected between the pedal support and the free ends of the pedals, each pedal having a downward rod at the fixed end and coupled to one connecting plate.

Abstract: A mounting device includes a trapezoidal plate with a tapered top edge and a bottom edge. A pair of ribs project from the bottom edge. Each of the ribs has a first portion and a second portion, the latter each having an engaging member at its end. The second portions are resilient and separated from the plate. The mounting device also has an attached body attached to a receptacle. The attached body includes a pair of attaching members, each of which has a channel and a guiding path formed in-between the channels. The trapezoidal plate can be inserted into the guiding path of the attached body to engage the same by the engaging members of the ribs.

Abstract: A front caster device for facilitating directing an infant stroller which comprises a bracket for mounting an axle along a transverse axis for rotatably mounting a ground supporting wheel thereto having a socket having an inner flange and a bushing adapted to be rotatably fitted and engaged in the socket by means of at least a flexible detent extending outwardly and upwardly from periphery of the bushing which is attached to a distal end of a front leg of an infant stroller.

Abstract: The present invention relates to an extendible rack assembly which comprises at least two bars with linking ends, a connector piece with two forked ends for connecting the two bars by engaging with the linking ends of the bars so as to extend the rack, a plurality of hook members with a mounting base, attached to the bars, which hook members are slideable along the extended bars, so that the user can extend the rack to any length needed and the hook members can slide to any location desired along the rack in practical use.
