DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to sports fitness equipment, and more particularly to sports equipment that can assist a user in exercising his lower body on a ground. Standing in [previous technology] Today's aerobic exercise equipment, treadmill, treadmill, elliptical, stepper, slider, etc. ★ elliptical machine can be The director and the user's feet are circulated on an approximate closed trajectory, which is very close to the circular motion of walking or running, and the impact on the joint is small, so (4) the response is excellent, = several years There is a trend of continuous expansion in the market. In general, the elliptical machine provides the basic principle of an approximately elliptical motion trajectory. The simplest and most common way is to move the mid-end of the foot support bar on a circular track of a crank mechanism and limit the other end. Or another miscellaneous-line recording on the reciprocating god, subtraction, the specific part of the cutting rod 卩 month b produces an approximately elliptical motion obstruction, such as the number (4) structure disclosed in the No. 557 patent. ^ However, as shown in the above patent, most of the foot struts of the foot struts are usually pivoted and rolled and rolled back and forth on the pre-track. The disadvantage of this structure is that "Roller surface and road": The groove is easy to change the dirt, you must find the clean core to transfer money smoothly; ^ ^ ri users in the transport of the material 'rolling back and forth the roller is easy to issue; 200902119 Of course, the traditional skills are also unused The elliptical machine of the roller has a typical structure in which one end of each leg support rod is pivotally connected to the outer end of the crank to be constrained to a circular trajectory, and the other end is connected to a swingable swing. The bottom end of the arm is constrained to an arcuate track, such as the structure disclosed in U.S. Patent No. 5,423,729, issued to the First Publication No. 2007/0117684. However, the amplitude of the movement of the pedal in the front-rear direction (or the length of the long axis of the ellipse) in the previously disclosed structure roughly corresponds to the diameter of the outer end of the crank, in other words, if sufficient amount of motion is to be obtained in production. , you need to configure a longer crank and take up a lot of space. SUMMARY OF THE INVENTION The main object of the present invention is to provide a sports equipment that can assist a user to perform similar walking or running sports. The foregoing sports equipment does not use rollers and rails, and therefore does not generate the aforementioned dust deposits and needs frequent cleaning and maintenance. The problem, and, when used, is less likely to produce noise or abnormal sound. Another object of the present invention is to provide a sports apparatus that can assist a user in performing a similar walking or running motion, which can obtain a pedal movement amplitude sufficient for the front and rear length with a relatively short crank. In order to achieve the foregoing objective, the sports equipment provided by the present invention comprises: a skeleton having a driving rod, a swing arm, a supporting rod and a connecting rod on each of the left and right sides; each driving rod has a first driving And a second driving portion, the first driving portion is pivotally connected to a corresponding crank of a crank mechanism on the skeleton, and the second driving portion is pivotally connected to a specific portion (first connecting portion) of the corresponding supporting rod; each swing arm The utility model has a pivoting portion and a swinging portion, and the connecting portion is pivoted 200902119. On the skeleton, the swinging portion is pivotally connected to another portion (the _th and the connecting portion) of the corresponding supporting rod; the first end of each connecting rod is pivotally connected On the corresponding driving rod, the mountain is pivotally connected to the corresponding swing arm; each branch pole also has a supporting portion for the user's foot of the branch building, which can be moved along a closed track. [Embodiment] Hereinafter, the structure of the embodiment of the present invention will be described in detail with reference to the accompanying drawings, and the functions and characteristics of the essence can be obtained. As shown in the figure, a sports equipment according to a preferred embodiment of the present invention mainly comprises a frame (10) placed on the ground, a crank mechanism (20) disposed at the front end of the frame (1〇), and a crank mechanism (20). ) Connected left and right two-way levers (4〇), left and right two swing arms (5〇) located behind the crank mechanism (2〇), connected to the bottom of the driving rod (40) and the swing arm (5〇) The left and right support rods (6〇) of the end, and the left and right two links (7〇) connected to the middle of the driving rod (40) and the swing arm (50). The main components of the aforementioned sports equipment are arranged in a bilaterally symmetrical form. The aforementioned skeleton (10) is used as a mounting base for other members, and has a flat base (11). The front half of the base (11) is connected to an upright frame (12). The rear side of the frame (12) A pillar (14) is connected between the rear end of the left and right crossbars (13) and the rear end of each of the lower rails (11). The left and right two pillars (14) are connected. The left and right two crossbars (13) and the rear edge of the frame (12) substantially define a movement space, and the user can enter and exit the space from the rear end of the skeleton (10). An instrument pole is protruded from the top end of the frame (12). (15) The top of the instrument panel (15) is provided with a meter (16). The crank mechanism (2〇) is located at the top end of the frame (12), and the main package 200902119 is pivoted to the frame according to the left and right axis ( 12) The upper crankshaft (21) and the opposite two cranks (22) fixed vertically to the left and right ends of the crankshaft (21) respectively. In addition, the frame (12) is also provided with a crank mechanism (2〇) a resistance device (30) for rotating resistance 'which mainly includes a flywheel (31) and an eddy current brake (ECB) (in the figure) Shown), the right side of the flywheel (31) is coaxially fixed to a small pulley (32). In contrast, the crankshaft (21) is also coaxially fixed to a large pulley (23) 'the aforementioned two pulleys (23) (32) Between the transmission belt (33) (see Figure 2), the eddy current brake is controlled by the above instrument (16) 'magnetic resistance can be used to control the rotational resistance of the flywheel (31) and the crank mechanism (2〇) In addition, the 'flywheel (31) can provide the rotational inertia of the crank mechanism (20). The aforementioned resistance device (30) is a conventional technique commonly used in the related art, and will not be described in detail herein. Left and right sides of the crank mechanism (20) Each of the driving rods (40) is disposed in a longitudinal direction, and the top end and the bottom end respectively form a first driving portion (41) and a second driving portion (42), wherein the first portion The driving portion (41) is pivotally connected to the outer end of the corresponding crank (22), and can rotate around the crank shaft (22) with the left and right axial crank shafts (21) as an axis. In addition, the driving rod (40) is also It is pivotally connected to the crank (22) according to the left and right axial directions, so that the bottom end can swing back and forth with respect to the top end. In the crank mechanism (2〇) Rearward, each of the left and right sides of the aforementioned movement space is provided with a swing arm (50). Each swing arm (50) extends longitudinally, and the aforementioned -1 swing arm (5 〇) each has a 4 section of the middle section. The connecting portion (51) is coaxially pivotally connected to the left and right crossbars (13) of the bobbin (10) such that the bottom end of each swing arm (5〇) forms a swinging portion (52) that can swing forward and backward. In addition, the top end of each swing arm (50) 200902119 # forms a swingable catching portion (53) for the user to capture & the swing arm (50) of the same side and the bottom end of the driving rod (40) Between each, it is connected by a support rod (60). Each of the support rods (6G) extends forward and backward, and a front end portion (61) is formed at the front end, and is pivotally connected to the bottom end of the corresponding driving rod (40) through the left and right axial pivots (ie, the second driving portion (42) ). Each of the support rods (60) forms a second connecting portion (62) at a substantially central position, and is pivotally connected to the bottom end of the corresponding swing arm (10) through the left and right shafts (ie, the swing cover portion (52)), so that the second connecting portion ( 62) is restricted to move on an arcuate trajectory centered on the swing arm (5 〇) pivoting portion (51). The rear end of each support rod (6〇) is fixed to a stepped pedal (63) to form a support portion for supporting the user's foot. In addition to the support rod (60), the aforementioned connecting rod (7〇) is respectively coupled between the swing arm (5〇) and the driving rod (40) of the same side, and in the present embodiment, each link ( 70) The first end (front end) is pivotally connected to the first driving portion (4) of the driving rod (40) and the second driving portion (42) through the left and right shafts (four), and at the same time, the second connecting rod (10) The end (rear end) is pivotally connected between the pivoting portion (51) of the swing arm (50) and the swinging portion via a pivot of the left and right axial direction. As shown in Fig. 3 and Fig. 4, with the above structure, the rotation of the crank (22), the displacement of the driving rod (10) and the oscillating motion of the swing arm (10) will be implicated on each other, so that it is below the angle of the specific crank (22). (4) The position and angle of the application; vice versa. Since the connecting portion (62) of the C segment in the cutting rod (10) moves on the curved path, the first connecting portion (10) of the fulcrum of the branch rod (60) moves on the closed arching so that the supporting rod (10)) The pedal (10) at the rear end will move 200902119 along the predetermined closed trajectory. Through the 180-degree relative arrangement of the left and right cranks (22), the left and right pedals (63) will show opposite movements in opposite directions, while 'when a side pedal (63) moves forward/backward The catching portion (53) at the top of the swing arm (5〇) on the same side will move backward/forward. When using the sports equipment of the present invention, the user enters the aforementioned movement space from the rear of the equipment, steps his feet on the left and right pedals (63), and holds his hands in the left and right grip portions. (53), the active output of the hands and feet (resistance to the resistance of the aforementioned resistance device (30)) causes the pedal (63) and the catching portion (53) to respectively move along the respective motions to thereby achieve the coordinated whole body movement of the hands and feet. Of course, the present invention can also be provided with a fixed grip so that the user can perform only the lower body movement. Since the roller and the rail are not used in the present invention, the above-mentioned accumulated dust and the problem of frequent cleaning and maintenance are not generated, and noise or abnormal sound is less likely to be generated during use. Furthermore, it can be seen from the third and fourth figures that the bottom end of the driving rod (4 〇) (ie, the second driving portion (42)) can move to be more forward and rearward than the range of motion of the crank (22). Position, therefore, by this amplification, the pedal (63) at the rear end of the mast (60) will move in the front-rear direction more than the outer diameter of the crank (22), in other words, the present invention can be relatively The short crank (22), that is, the crank mechanism (2 〇) that takes up less space, gives a sufficient pedal movement amplitude of the front and rear length. The above detailed description merely discloses a preferred embodiment, but in the implementation of the present invention, it is possible to make a substantial change or replacement of several structures under the aforementioned inventive spirit and inventive features. 4〇) and pendulum 200902119 = even the aforementioned connecting rod (7 °), you can let the support rod (6 °) and the crank ^ 'however' the connecting rod (10) front end is not limited to the above as Γ = at:, (10) The driving portion (41) and the second driving portion, 5 may also be modified to be driven by the first rod and then extended upward or by the second driving portion (42), and the connecting rod is missing. (7G) The front end is pivotally connected above the first driving portion (8) or below the second belt 丄, 2). Similarly, the rear end of the connecting rod (10) does not limit the pivoting portion (51) pivotally connected to the pendulum #(50). Between the pendulum (52). In addition, because the pivotal position of the connecting rod (70) on the driving drought (40) or the swing arm (50) indirectly determines the shape of the pedal (10) movement (including the length and width and the inclination), so "we can also The driving rod (for example, and/or the swing arm (5〇) is preset with a plurality of turning positions, so that at least the end of the connecting rod (7) is on the side of the rod (4) or the pen f(10)) One of the Tingyi locations' allows the user to set the trajectory of the pedal (63) according to individual needs.
