Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention is related to a treadmill for skiing-like exercise, and especially to such a treadmill for skiing-like exercise which is provided on its base with a supporting column, and is provided on two lateral sides thereof with a left and a right linkage respectively; each linkage has a peddle of which one side is connected with a ski stick, each peddle is connected on its front end with a linking member pivotally connected to one side of the supporting column and controlled by a movable flexible member. The rear end of each peddle is connected with an up-bracing buffer to form impedance force to render a user to do treading exercise in a crossed way and in an inclining mode as if the user is skiing; the treadmill is suitable for plastic art on a waist, a hip and a thigh etc.
2. Description of the Prior Art
In the present society, people mostly are busy at their own businesses and works, their paces are quite fast, relatively, they leave very little time for them to do exercises outdoors; however, people are unable to fight in their vocational fields with long last if they do not have healthy bodies. In order to render people to also get the effect of exercising for attaining health indoors, various types of gymnastic instruments have been being developed.
Indoor gymnastic instruments available presently are variant, they include, for example, treadmills, indoor exercise bikes and tread exercising machines exercising frontwards and rearwards or leftwards and rightwards. The abovementioned indoor gymnastic instruments can render users to get the effect of exercising for attaining health, but they mostly are products individually with only a single function, and can only be used to exercise a part of a body, this inevitably misses some parts untreated in plastic works; and in use of the abovementioned indoor gymnastic instruments, the instruments are mostly for exercises with two feet of a man moving parallelly, there is no effect of exercise with two feet twisting in a crossed way. Therefore, they are unable to make plastic exercise on the muscles on the inner sides of thighs.
In view of the above defects to be solved, and for the purpose that a treadmill for skiing-like exercise can do treading exercise in a crossed way and in an inclining mode as is in skiing to thereby be suitable for plastic art on a waist, a hip and a thigh etc., the present invention is developed after nonstop studying and improvement based on professional experience of years of the inventor.

The central area of the front supporting rod 21 is provided with a square central supporting column 24 having therein a through hole 241 extending from its front side to its rear side; the front end of the through hole 241 is provided with an inner thread 242. The central supporting column 24 is provided on its top with a display 25 to display the distance of treading and the amount of heat consumed etc. during exercising of a user. The central supporting column 24 is provided further on two lateral sides with bearing pieces 26, 26′ respectively inclined downwards, the bearing pieces 26, 26′ are connected respectively on their bottoms with bracing rods 27, 27′.
The left and the right linkages 3, 3′ are symmetrically provided on the two lateral sides of the central supporting column 24, the linkages 3, 3′ each has a peddle 31 (31′) which is connected on its bottom with an elongate engaging block 32 (32′); the front end of the engaging block 32 (32′) is connected to a linking member 33 (33′) in the shape of a straight rod and able to be coaxially connected to the bracing rod 27 (27′). The two linking members 33, 33′ are symmetrically provided in inclined positions respectively on the two lateral sides of the central supporting column 24 to allow rotation of the two linking members 33, 33′. The linking member 33 (33′) is provided with a radially protruding sheet 34 (34′). The engaging block 32 (32′) is provided on the bottom of its rear end with an elongate fixed post 35 (35′) to connect to an end of a buffer 36 (36′); the other end of the buffer 36 (36′) is connected to the front supporting rod 21 to brace up the peddle 31 (31′) for forming a resistant force against treading.
The left and the right ski sticks 4, 4′ are provided respectively with fixed rods 41, 41′ and holding rods 42, 42′, the fixed rods 41, 41′ are both in the shape of “L” which each has an end of a transverse section connected to the fixed post 35 (35′) of the peddle 31 (31′), and which each has an upright section having a universal joint 43 (43′) and a reduced pipe 44 (44′); the reduced pipe 44 (44′) has a snap engaging member 45 (45′), the holding rod 42 (42′) is provided on its bottom with an engaging hole 46 (46′) to receive the snap engaging member 45 (45′) on the reduced pipe 44 (44′), thereby the fixed rod 41 (41′) can be connected with the holding rod 42 (42′).
The supporting rack 5 is a frame-like member having on one end thereof a cylindrical protruding portion 51 that can be inserted into the through hole 241 of the central supporting column 24 of the base 2 for connection. The upper and the lower ends of the supporting rack 5 are provided with positioning holes 52 for mounting thereon a wheel 53 connecting on its periphery with a flexible member 54; two ends of the flexible member 54 are respectively connected with the two the protruding sheet 34, 34′ of the left and the right linking members 33, 33′.
The housing 6 covers from above the base 2, and includes a front housing portion 61 and a rear housing portion 62; the front housing portion 61 has a round recess 63 having therein a through hole 64 for extending therethrough of a screw rod 71 of an adjustment screw 7 to connect with the inner thread 242 at the front end of the through hole 241 of the central supporting column 24.
Referring to FIGS. 4, 5, by virtue that the screw rod 71 of the adjustment screw 7 is coaxial with the protruding portion 51 of the supporting rack 5, when in rotating the adjustment screw 7, the screw rod 71 can be forwarded or retracted to push the protruding portion 51 of the supporting rack 5, this can link up with the supporting rack 5, the wheel 53 and the flexible member 54. By the fact that the two ends of the flexible member 54 are respectively connected with the two the protruding sheet 34, 34′ of the left and the right linking members 33, 33′, rotation of the two linking members 33, 33′ can allow height adjustment of the left and the right peddles 31, 31′.
Referring to FIGS. 2, 6, when the user treads on the right peddles 31, the rear end of the right peddle 31 is pressed down, the engaging block 32 beneath the right peddles 31 and the right linking member 33 rotate counterclockwise about the bracing rod 27 (as an axle) to pull one end of the flexible member 54 to move counterclockwise; meantime, the other end of the flexible member 54 links up with the left linking member 33′, so that the rear end of the left peddle 31′ moves upwardly (as shown in FIG. 7).
When the user treads on the left peddles 31′, its linking function goes in a contrary direction to that stated above, thereby the left and the right peddles 31, 31′ can move up and down in inclined positions respectively. And the user can allow two hands to respectively control the actions of pushing and pressing on the left and the right ski sticks 4, 4′ to do treading exercise in a crossed way and in an inclining mode as if the user is skiing in different directions respectively; the object of doing plastic art on a waist, a hip and a thigh etc. can thus be attained.
Accordingly, the present invention has the following advantages:

1. The present invention allows a user to do treading exercise in a crossed way and in an inclining mode; this allows plastic art on a waist, a hip and a thigh etc. of the user.
2. The present invention allows two peddles to move directions in a crossed way and in an inclining mode by using ski sticks rotatable in multiple; this can allow treading exercise as if the user is skiing, and can increase the effect of exercise and fin of using.
3. The rear ends of the peddles of the present invention are connected respectively with buffers that not only can brace the weight of the user, but also can form impedance force against treading to increase the effect of exercise.
4. The present invention can adjust the height of the peddles in pursuance of the requirement of the user to provide different effects of exercising in use.

In conclusion, according to the content disclosed above, the present invention can get the expected object thereof to provide a treadmill for skiing-like exercise that renders a user to do treading exercise in a crossed way and in an inclining mode as if the user is skiing; the treadmill is suitable for plastic art on a waist, a hip and a thigh etc.
