New description: [New technical field] This creation is related to sports and fitness equipment, especially for an elliptical exercise machine (Elliptieal) that is convenient for the user to go up and down the pedal. [Prior Art] An elliptical exercise machine is a type of exercise body that can carry the user's feet with the left and right pedals, and then guide the feet to move on an elliptical track. Today's common elliptical exercise machines usually support two pedals, one left and one right, and the two support pedals, the support rods extend forward and backward, one of which is on the crank mechanism and can be wound around the circle, the other end Then, the back and forth reciprocating displacement on the predetermined trajectory can be performed, so that the pedal supported by the pedal can move on the elliptical obstruction. In addition, most of the elliptical movements today have a front and rear swinging grab bars, and the bottom end of the handrail bar is connected with the aforementioned support rods or pedals by hand and foot links, thereby achieving a 1" For the user to catch the front end, and the day ^ grab bar or solid grip) are located in the end of the exercise machine, if the rear end of the shaft machine is not equipped with the aforementioned crank mechanism, the user is " ί, The guide that can reciprocate and slide, so in general, when the elliptical exercise machine is made to the right side, most of the left side or side of the exercise machine will go down the left side Γ4 two pedals' when the movement ends, it is also On the side of the pedal, you can't think about it. When the user wants it, "the real type is not used by the side of the elliptical machine. ^__false M321309 is the right side - when the pedal is crossed, The above-mentioned branch poles, connecting rods and pedals on the right side of the exercise machine will hinder the user's left foot from being directly separated by the ground-segment distance_left_board' (four) is, #右_板 is unfortunately staying above When the position of the left pedal is used (the shirt may be used on the left side of the exercise machine), it will show a leap. It. [New content] The present invention aims to improve the above disadvantages, and the main object is to provide an expansion exercise machine which allows a user to step on or off conveniently and safely. In order to achieve the foregoing objectives, the elliptical exercise machine provided by the present invention comprises a skeleton; the left and right support rods are movably disposed on the skeleton; the left and right pedals are respectively directly connected by the two support rods or Indirect support, and guided by the support rod to move on a closed track; characterized in that: the rear end of the circular motion machine is opened > into an access space, allowing the user to step on the two pedals from the rear, or The two pedals are moved back and forth from the ground. The skeleton has left and right side portions respectively located on the left and right sides of the entrance and exit space, and a top portion of each side portion is provided with a catching portion for the user to step on.捉Catch when you leave the pedal. [Embodiment] Hereinafter, the structure of a preferred embodiment of the technical features of the present invention will be described in detail with reference to the accompanying drawings, and the functions and features which can be obtained. Please refer to the drawings. The elliptical motion of a preferred embodiment of the present invention includes: 匕M321309~skeleton (10), which mainly includes a bottom portion that can be stabilized on the ground), and the left and right sides of the left and right sides are known ( (8). As in the first and second sides, the left and right sides (13) form a front-to-back pass (=4), and the second half of the bottom of the skeleton (8) presents an open U-shaped shape. That is to say, the trailing edge is not connected to the left and right, and the bottom of the space (10) also exhibits a completely open shape. The struts (15) of each of the struts (the top end of the (5) are protruded from the bottom right. In addition, the foot support portion (16), in this embodiment, the catching portion (16) is a soft carcass 'capable for the user to grasp with the palm facing downward. A crank mechanism (30), located in the skeleton The left and right sides of the cover (π) of the front end portion (12) are exposed at opposite ends of the shaft (31). At the same time, the inside of the shell (17) is also provided with resistance to the crank mechanism (30). The device (not shown) causes the crank mechanism (3〇) to resist a predetermined resistance when it is rotated. However, this part is a well-known technique and will not be described in detail. Left and right The cantilever (40) is disposed at the rear end of the skeleton (1〇) and interposed between the one side portions (13), each extending longitudinally, and the top end is connected to the top end of the corresponding side of the strut (15), and the bottom end can be front and rear In detail, the top end of the cantilever (40) of the present embodiment is fixedly connected to the aforementioned catching portion (16), and the two (40) (16) are pivotally connected together at the top end of the strut (15), in other words, The catching portion (16) slightly changes the inclination of the top surface as the cantilever (40) oscillates. The left and right two support rods (50) each extend forward and backward, and the front end is pivotally connected to the corresponding side of the crank mechanism (30). The contact point forms a rewinding portion that can be rotated along a circular path; the rear end is pivotally connected to the bottom end of the cantilever (40) of the corresponding side, and the shape M321309 is oscillated back and forth along an arcuate path (T). The position (refer to Figure 3). The left and right handrail bars (60) are disposed at the front end of the skeleton (10), each extending longitudinally, and a predetermined portion of the intermediate section is spliced to the front end of the skeleton (10). (12) 'Make the top end (forming the movable grip (61)) and the bottom end swing back and forth. Left and right two pedals (70), respectively, left and right Supported by the support rod (50). In this embodiment, each pedal (7()) directly pivots its front end to the top surface of a selected position between the front and rear ends of the support rod (50), thereby The end can be deflected up and down with respect to the support rod (50). The front and rear ends of the support rod (5〇) are respectively guided on a circular trajectory and an arc-shaped trajectory, so that the pedal is interposed between the two ends of the support rod (50). (7〇) is guided to move on a closed elliptical trajectory. Left and right links (80), each extending forward and backward, the front end is pivotally connected to the bottom side of the corresponding side of the grab bar (60), the rear end Then, it is fixed with the corresponding side pedal (7〇), so that the handrail lever (70) can be driven together with the pedal (70) and the support rod (5〇), and the angle of the pedal (70) relative to the support rod (50) It can be cyclically changed during exercise to provide better ergonomics (known skills). In another conventional structure, the connecting rod is pivotally connected to the support rod at the proximal end thereof, and the pedal is fixed to the rear end of the connecting cup (not directly pivoted on the supporting rod), that is, the pedal is supported by the branch The rod is indirectly supported, but the aforementioned linkage effect is the same. With the above structure, the user can step on the left and right pedals (70) with both feet, and grasp the hands on the tops of the left and right handrails (6〇), and apply force to the pedals (70). And the grips (61) move along their respective tracks and lead M321309 to each other for joint movement. Of course, the user can also select the fixed grip (a) preset at the top end of the front end portion (12) of the skeleton (10) to perform only the lower body movement. Wherein, as shown in FIG. 2, in the present embodiment, the strut (15) for supporting the cantilever (40) is disposed on the skeleton in a controllable manner, and further, each The bottom end of the strut (15) is pivotally connected to the frame (19) of the side portion (13), and a driving rod (21) is continuously extended downward from the bottom end of the strut (15), and at the same time, in the aforementioned frame (19) The inside (usually covered by the cover (22)) is further provided with a driving device (9). The driving device (90) mainly comprises a motor (91) and a screw (92) which can be driven by the motor. The tail end of the rod (21) is screwed onto the screw (92), so that when the motor (91) is operated, the rod (15) can be driven to deflect the bottom end thereof. The change of the inclination of the strut (15) means that the top end of the cantilever (4〇) is displaced, so that the swinging of the bottom end of the cantilever (4〇) and the rear end of the support rod (50) is changed, thereby adjusting the pedal. (70) The movement is obsessed. In another embodiment of the present invention (not shown), the left and right sides of the skeleton each have a crossbar extending as a posterior, and the top end of the cantilever is suspended in a front-rear manner. On the crossbar. The aforementioned catching portion may be provided on the aforementioned crossbar. The main features and functions of the elliptical exercise machine provided by this creation are as follows: When the user wants to use the elliptical exercise machine, the left and right pedals can be stepped forward by the rear of the exercise machine via the seven entry and exit spaces (14). ), when the use is over, the pedal (70) can also be moved down the ground through the access space (14); and during the step of stepping on and off the pedal (70), the user can temporarily assist the left and right when M321309 The side of the catch (16) to maintain the stability of the footsteps.
