Abstract

A walk simulating machine includes two pedal connect rods 40, a horizontal rod 31, two side connect rods 50 consisting of an upper 51 and a lower connect rod 52, and a stop member 73 in front of each upper connect rod 51. The lower connect rods 52 sway together with the pedal connect rods 40. The upper and the lower connect rods sway straight if the upper connect rods are not stopped by the stop member 73; the lower connect rods 52 solely sway if the upper connect rods 51 are stopped. So the walking orbit of the pedals may have different centers in the two different conditions. The front end portion of the walking orbit bends up, letting the heels land on the ground first for a user to stand stably (see Figures 7, 9, 11). Further, a slope adjuster is provided to adjust the angle of the stop members 73 relative to the upper connect rods 51 for making three modes of exercises, namely walking on the flat (Figure 6A and 7), walking uphill (Figures 6B and 9), and walking downhill (Figures 6C and 11).

Description

241 3094
WALK SIMULATING MACHINE
This invention relates to a walk simulating machine, particularly to one having pedals which move in an orbit a little different from the orbit of a known walk simulating machine which provides pedals which move in an egg-shaped oval.
Preferred embodiments of the present invention seek to prevent the body of a user from Inclining towards the front side as can arise when using the known walk simulating machine, so that a user may advantageously use the walk simulating machine for bodily exercise In a stable posture without falling off the machine.
In a previously proposed walk simulating machine the movement of the pedals when pushed by the feet of a user follows a generally egg-shaped oval orbit, as shown In Fig. 1. The front portion of the orbit is comparatively pointed and the circular rear portion of the orbit is comparatively dull (the front half portion of the walking orbit being Inclined downward.) When a user treads on the pedals to allow the pedal connecting rod to extend upward, the body of the user may incline forward and may become unstable because of the position of the user's center of gravity In order to avoid inclining forward, the user may put the (lean so as to shift his) center of gravity on the toes of the feet. This mode of walking, with the center of gravity placed on the toes is different from that of a common walking mode. Moreover, walking with the center of gravity on the toes for a certain period of time may harm the foot or produce cramp So the previously proposed walk simulating machine is not ideal for carrying out walking exercise from the viewpoint of ergonomics.
Preferred embodiments of the present invention seek to provide a walk simulating machine having pedals which move in such an orbit that a front end portion of the orbit bends up a bit (inclines upwards) so a user's heel may land on the ground first (with the center of gravity located at the heel) when a foot moves forward. Thus, a user can advantageously carry out walking exercise with the center of gravity substantially stable, and the walking orbit may advantageously conform to ergonomics.
Preferred embodiments of the invention comprise two pedal connect rods, and two side connecting rods fixed respectively at two sides of a horizontal rod and respectively consisting of an upper connect rod and a lower connect rod pivotally connected with each other Further, a stop member is preferably provided in front of each upper connect rod, and the lower ends of the lower connect rods are preferably pivotally connected with the pedal connect rods to advantageously sway back and forth together with the pedals fixed with the pedal connect rods The upper and the lower connect rods advantageously sway straight synchronously when the upper connect rod does not collide with the stop members. The lower connect rods preferably only sway solely when the upper connect rods collide with, and are stopped by, the stop members. Therefore, the walking orbit that the front ends of the pedal connecting rods form is different in the two conditions just mentioned so the walking orbit may advantageously have the front end portion bending up a little (inclining upwards), thereby allowing a user to conduct stable walking exercise, with the heels of the feet landing on the ground first, conforming to ergonomics.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made, by way of example to the accompanying drawings In which: Figure 1 Is a perspective view of a moving orbit generated by a previously proposed walk simulating machine, Figure 2 Is a perspective view of a walk simulating machine embodying the present invention, Figure 3 Is side horizontal view of the walk simulating machine embodying the present invention; Figure 4 Is a partial front view of the walk simulating machine embodying the present invention; Figure 5 Is an upper view of the front portion of the walk simulating machine embodying the present invention, Figure 6A is a front view of a slope adjuster in a horizontal condition embodying the present invention; figure 6B Is a front view of the slope adjuster in a slope-up condition embodying the present Invention, Figure 6C is a front view of the slope adjuster in a sloped-up condition embodying the present Invention; figure 7 Is a perspective view of a walking orbit generated by the walk simulating machine In the horizontal condition embodying the present invention; Figure 8 is side view of the walk smulabng machine with pedals moving In a sloping-up condition embodying the present invention; Figure 9 is a perspective view of walking orbit generated by the walk simulating machine in a sloping-up condition embodying the present invention; Figure 10 is a side view of the walk simulating machine with pedals moving In sloping-down condition embodying the present invention; and, Figure 11 Is a perspective view of a walking orbit generated by the walk simulating machine in a sloping-down condition embodying the present invention.
A preferred embodiment of a walk simulating machine in the present invention, as shown in Figs. 2 and 3, includes a base 10, a crank unit 2O, a front post 30, two pedal connecting rods 40, two side connect rods 50, two connect rods 60, and a slope adjuster 70 as main components combined together.
The base 10 is to be laid on the ground to support the other components just mentioned above.
The crank unit 20, as shown in Fig. 3, is located on a rear portion of the base 10, having two cranks 21 respectively connected pivotally at two sides. The two cranks 21 are positioned at 180 degrees'difference.
The front post 30 is fixed on a front end of the base 10 extending upward, having a horizontal rod 31 extending to two sides from the upper end as shown in Figs. 2 and 4 The front post 30 further has a hand slide member 32 respectively at two outer sides, and two slide rollers 33 respectively at the outer side of the side member 32 and forming an aperture 34 between them.
The two pedal connecting rods 40, as shown In Figs 3, are located respectively at two sides of the base 10, having the rear end connected pivotally to one end of each crank 21 and a pedal 41 fixed on an upper surface for a user's foot to tread on.
The two side connect rods 50, as shown in Figs. 2 and 3, are located vertcaily respectively at the two outer sides of the front post 30, respectively consisting of an upper connect rod 51 and a lower connect rod 52 pivotally connected with each other.
The upper connect rod 51 has its upper end pivotally connected to the horizontal rod 31, and the lower connect rod 52 has its lower end connected pivotally to the front end of the pedal connecting rod 40 The two hand gripping rods 60, as shown in Figs. 2 and 3, are located respectively at two sides of the front post 30, having their lower ends pivotally connected to the front ends of the pedal connecting rods 40, and the upper ends extending upward through the apertures 34 of the two slide rollers 33 as shown in Fig. 4, with their upper ends held by the hands of a user.
The slope adjuster 70, as shown in Figs 2 and 4, Is located below the horizontal rod 31, having a slope rod 71 laterally passing through the front post 30, having two ends located at two sides of the front post 30. Two cranks 72 is fixed respectively at two ends of the slope rod 71, having the other ends respectively connected pivotally to two stop members 73 located at the front of the upper connect rods 51. The slope adjuster 70 further has a position disk 74, as shown in Figs. 4 and 6A, having one side surface fixed with a left side of the front post 30, and the other side provided with a apluality projecting curved ribs 740, a plurality of recesses 741 respectively provided alternately with the ribs 74O, and an slender recess 742 formed in the curved ribs 740.
Further, the slope adjuster 70 has an L-shaped adjust rod 75, as shown in Figs. 4 and 5, and the adjust rod 75 has the upper end fixed vertically with the slope rod 71, and the lower end extending forward the front post 30, moving together with the slope rod 71 Further, the slope adjuster 70 has a locking tenon 76 provided with one end 760 laterally extending through the slope rod 75 and fitting in one of the recesses 741 and pushed by a spring therein to shift Moreover, the slope adjuster 70 has a push rod 77 with its intermediate section pivotally connected to the adjust rod 75, and one end fitting in the gap between the adjust rod 75 and the end 760 of the locking tenon 76.
When the push rod 77 is pulled to the adjust rod 75, the other end of the push rod 77 moves the end 760 of the locking tenon 76 to compress the spring therein, forcing the end 760 to separate from one of the recesses 741 as shown by the arrow in Fig. 5 In this way, the adjust rod 75 can move the slope rod 71 when pulled, with the stop rod 73 also shifted at the same hme and changing the stopping angle for swinging of the upper connect rod 51. The adjust rod 75 is manually handled, but it can also be controlled electrically, for example by a motor.
In using the walk smulabng machine, there are three modes described below, referring to Figs. 2 and 3.
l Using it in a horizontal condition. In this condition, the upper connect rod 51 is stopped by the slope adjuster 70 to position vertically as shown in Figs 3 and 6A. When two feet of a user stand on the pedals 41 with two hands gripping the upper ends of the hand gripping rods 60, the user moves hand gripping rods 60 to let the pedals 41 treaded by the feet move in a walking orbit shown In Fig. 7 The walking orbit is interrupted in case of the upper connect rod 51 coming to contact with the stop rod, so that the lower connect rod 52 swings together In a straight line with the upper connect rod 51 until the upper connect rod 51 contacts with the stop rod 73 At the moment the upper connect rod 51 Is stopped Immovable by the stop rod 73, the lower connect rod 52 may swing Independently with the function of the pivotal point of the upper and the lower connect rod 51 and 52 as an orbit center, forming the walking orbit shown in Fig. 7.
2. Using it in a sloping-up condition. In this condition, the stop rod 73 is moved rearward by handling the adjust rod 75 and fixed in that position. Then the walking orbit formed by the pedals 41 will be the one shown in Figs. 8 and 6B, with the front section of the orbit bending up as shown in Fig. 9. Thus, a user can get training as If walking up a slope.
3 Using it in a sloping-down. In this condition, the StOp rod 73 is moved forward and secured stably in that position as shown In Figs. 6C and 10. Then the walking orbit of the pedals 41 has its front end sloping down, as shown in Fig. 11, and a user can use the walking simulating machine for training of walking down a slope.
As the upper connect rod 51 has a stage of swaying and a stage of stopping by means of the stop rod 73 located in front of the upper connect rod 51, so the center of the walking orbit of the lower connect rod 52 during the straight movement is different from that during non- straght line movement. Therefore the walking orbit formed by the pedals 41 may have its front end portion bending up a little, forcing the user to land on the ground with his heels first when training walking in this condition, with the user's posture being in a stable condition conforming to ergonomics. Furthermore, in the slopng-up and the sloping-down condition of the walking simulating machine, the walking orbit formed by the pedals 41 is also the same as the horizontal condition, with the front end portion bending up a little, obtaining better function than the conventional walking simulating machine In addition, when the slopng-up angle is adjusted to the largest, the upper connect rod 51 has no swaying stage, while the lower connect rod 52 has a swaying stage On the contrary, when the slopng-down angle Is adjusted to the largest, the upper and the lower connect rod 51 and 52 sway synchronously in the whole orbit.
Lastly, referring to Fig 9, as the upper end of the hand connect rod 60 moves in an S shape In the walking orbit, it is easy for the user to use more manual force While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are Intended to cover all such modifications that may fall within the scope of the invention.
