New description: [New technology field] In particular, it relates to a variable stride. The present invention relates to a sports equipment for sports equipment. [Prior Art] Elliptical exercise machine is a four-year leg exercise equipment in recent years. Generally, it can guide the left and right pedals along an approximately elliptical walking movement, so that the user can perform leg movements like walking and running. s installation. Most of the pedaling traces described above are flat and long closed curves which are wider in front and rear and narrower in upper and lower directions, and the length of the long axis is generally referred to as stride or stroke. It is conceivable that a longer or shorter pedal stroke would correspond to a larger or smaller leg movement and would generally be more suitable for taller or shorterer users. However, the pedaling of an elliptical exercise machine is almost always fixed, so that all users must move to a given movement. In contrast, there are also a small number of conventional elliptical exercise machines, such as those disclosed in U.S. Patent Nos. 6,719,666 and 6,994,656, which are available to the user for their personal height, habit, or time. The amount of exercise required 'moderately adjusts the pedal's motion stroke by setting the spatial relationship manually or electrically. Further, U.S. Patent No. 6,689,019 discloses an elliptical exercise machine in which the pedal stroke can be changed instantaneously as the user moves. Furthermore, there is a tendency in the industry to replace a part of the connecting rod with a flexible member. For example, an elliptical machine has at least one frame, a crank system and a connecting rod set on the frame, wherein the crank system includes two crank arms, and the connecting rod The group includes two swinging members, a yam and a two-flexible first end respectively pivotally connected with one end of the two rocking members quoted by the curved cylinder wall, and the front end is connected with the second end of the foot support respectively The first ends of the two flexible members are respectively connected to the frame, and the ==r'TM flexible member has the disadvantage of == two, such as ★ the addition of the aforementioned flexible member, so that =:: (the lateral swing generated by it) Affecting the effect of exercise. [New content] The main technical problem to be solved in this creation is the disadvantage of the relatively unstable technology in the prior art of applying the flexible core of the flexible part. The present invention solves the variable stride by the following technical solutions. The sports equipment comprises: a front and rear extended base surface extending upward from the base; a left link mechanism comprising a first-left link set and a third: said left-handed first-money material includes - The left swing member and the left foot branch member respectively The first connecting portion has a second connecting portion==the cow's first==the connecting portion is pivoted on the branch frame, and the first connecting portion of the left swinging left foot supporting member is pivotally connected to each other, where (4)::,,, The plane of motion consisting of at least two links and having at least a pivotal portion and a second connecting portion of the left foot support is two:

As can be seen from Fig. 6, they respectively protrude from the outer circumferential edge of the wobble plate 62. The connection end. Preferably, the first connecting rod and the second connecting rod are first fixed to a sleeve at an angle, and are sleeved on the second mounting shaft 1B and located on the right side of the wobble plate, and then the first connecting rod passes the screw Fixed with a swinging disc. Preferably, the angle between the above connecting rods is 120 degrees. Naturally, other alternatives can be readily conceived by those skilled in the art, such as directly welding the two connecting rods to the right side of the wobble plate at an angle, in such a way that the bushings described above can even be omitted. The synchronous reverse motion unit 60a further includes a left link set and a right link set, wherein the left link set is pivotally formed by the two links 64a and 65a and has a first end and a second end, the first end and the left swing The first connecting portion of the 11 M378001 piece is fixed, the second end is connected to the connecting end of the first connecting rod 63a, and the right connecting rod group is pivotally connected by the two connecting rods 64b, 65b and has the first end and the first: 3⁄43⁄4 First, the first connecting portion is fixed to the right swinging member, and the second end is fixed to the connecting end of the first connecting rod 63b. Referring to FIG. 8, the left and right swings are caused by the complexity of the creative structure. The first connecting portion of the piece is symmetrically spaced apart from the outer side of the vertical surface formed by the first connecting rod and the second connecting rod, respectively, and the ends of the connecting rod 64a and the connecting rod 64b are respectively fixed. The left end and the right swing member 'the second end are respectively connected to the connector 65a, 65b, so the link 64a and the link 64b must spatially form a vertical surface formed by the first connecting rod 63a and the second connecting rod 63b. The extension and movement of the strands 65a and 65b in a plane perpendicular to the mounting axis ΐβ. The present invention configures the links 64a and 64b such that a rod 64a-1, 64b-1 extends circumferentially outward from the first connection end of the left and right swing members and forms a fixed end; a rod 64a One ends of -2, 64b-2 are respectively fixed to the above-mentioned fixed end, and extend parallel to the mounting shaft 1A to form a vertical plane of φ formed by the first connecting rod and the second connecting rod and form a second fixed end; a rod 64a-3 One of the 64b-3s is respectively fixed to the second fixed end, and the other end is pivotally connected to the connecting rods 65a, 65b, respectively. A resistance unit 60b includes a reluctor wheel 66 rotatable about the mounting shaft 1C, and the reluctance wheel 66 forms a transmission wheel 67 to the right in the axial direction. The drive belt 61 is tensioned between the wobble plate 62 and the drive wheel 67. Preferably, the circumferential annular region of the wobble plate 62 has an opening, and a tensioning block 68 is locked at the opening of the wobble plate 62 by the locking bolt 69a, and rotates clockwise with the locking bolt 69a as a starting point. An angle, a adjusting nut 6% is fixed to the wobble plate 62. When the tensioning 12 M378001 block 68' is rotated counterclockwise by the adjusting nut, the transmission belt 61 is tensioned; when the transmission belt 61 is tensioned to a certain extent, the tensioning block 68 can be locked by the locking bolt 69a. The reaction force of the belt 61 is applied to the locking block 68 to lock the locking bolt 69a tighter. More preferably, the outer circumferential surface of the tensioning block 68 further has teeth, and the aforementioned belt 61 may be a timing belt, and the timing belt is intermeshing with the aforementioned teeth to make the transmission more reliable. Referring to FIG. 7, when the user swings the grip 54a forward or swings the swing grip 54b backward, since the left grip 54a and the right grip 54b are respectively coupled to the staggered links 64a, 64b to the left swing member 43a, The first connecting portion 'the north of the right swinging member 4 is freely rotatable relative to the first mounting shaft 1A, so that the staggered connecting rod 64a can be rotated clockwise or the connecting rod 6 can be rotated counterclockwise to respectively drive The links 65a, 65b are swung, such oscillations cause the wobble plate 62 to rotate clockwise, and due to the presence of the drive member φ 61, the drive wheel 67 causes the reluctance wheel 66 to also rotate clockwise. As shown in Fig. 6 9~1, a crank disk π is fixed on the first mounting shaft 1 ,, and the crank arms are fixed at a (10) degree angle to the mounting shaft __the aforementioned curved (four) symmetrical arrangement. The rotary resistance system 7 includes a pulley 71 and a generator flywheel 72. The pulley 71 is disposed on the first mounting shaft 1B, and is formed along the left and right axial directions - a large pulley 3 and a small pulley 74, the aforementioned generator flywheel 72 is disposed on the third mounting shaft ic, and the «^ wheel 72 is further formed on the left and right axial directions - a small pulley π. Between the aforementioned large leather π wheel 73 and the small pulley 74 and between the generator flywheel and the small pulley 75, it can be formed by casting, through the key connection between the large and small wheels, or by fixing the small wheel to the large wheel. Such as the prior art to the real 13 M378001 now. Referring to Figures 10 and 11, it can be seen that on the plane perpendicular to the mounting shaft, the small pulley 74 of the pulley 71 is disposed corresponding to the crank disk with a belt disposed therebetween; the small pulley 75 of the generator flywheel 72 and the large pulley 73 of the pulley 71 Corresponding to the setting, a belt is placed between them. Preferably, a 'sonic wheel 78 is provided on the auxiliary mounting shaft id, and the belt 76 is pressed against the outer side of the belt 76 so that the belt 76 is not loosened. The specific structure of the aforementioned generator flywheel 72 should belong to the prior art, and therefore will not be described herein. Because the crank arm and the crank disk are fixed to the first mounting shaft 1 所以, when the flexible member drives the crank arm to rotate, the crank arm drives the first mounting shaft to rotate to drive the crank disk to rotate accordingly, due to the belt 76 and the belt 77 The presence of the pulley 71 and the generator flywheel 72 will also rotate. In addition, since the diameter ratio of the crank wheel relative to the small pulley 74 of the pulley 71 and the large pulley 73 of the pulley 71 to the small pulley 75 of the generator flywheel 72 is greater than 1, the rotary resistance system has the function of speed amplification, that is, it is advantageous for the hair. The power generation of the motor. It can be seen from the above description that the synchronized motion system and the rotary resistance system of the present invention are independently moved, that is, the former is the front and rear swings of the grips 54a and 54b or the swinging members 43a and 43b around the mounting shaft 1A, and the synchronous reverse motion unit 60a. The driving resistance unit 60b is configured to perform a clockwise or counterclockwise movement, and the latter is a flexible member 55a and 55b. The cranking arms 35a and 35b of the crank system 34 are rotated circumferentially and the mounting shaft 1A for driving the same is also rotated. 1A drives the crank disk 37 to rotate synchronously so that the rotary resistance system 7 〇 operates. When the user uses the apparatus with both feet standing on the pedals 46a and 46b, if only 14 pairs of pedals 46a and 46b apply a vertical force, the crank system 34 will drive the rotary resistance system 70 to move while the rocking members 43 & and 43b basically Not participating in the exercise or just participating in a small part of the exercise, correspondingly, the synchronized motion system 60 is also substantially motionless; when the user's feet stand on the pedals 46a and 46b and the left and right hands also operate the grip 54a and respectively At 54b, since there is both up-and-down motion and front-rear movement at this time, the up-and-down motion causes the crank system 34 to drive the rotary resistance system 7 〇 working 'front-back direction movement causes the swing members 43a and 43b to drive the synchronous motion system 60 work' so the rotary resistance system 7〇 and the synchronized motion system 60 are all involved. In addition, with the design of the present creation, the user can continually change the force applied to the horizontal direction of the apparatus to obtain a varying stride 'more precisely, the user can change the force applied to the grips 54a and 5 The horizontal force applied to the pedals 46a and 46b by the feet is changed, and since the stride is varied due to the change in the horizontal force, the user can change the stride indefinitely 'well, ideally, the user usually chooses the fit Your own most comfortable step. 15 [Simple description of the drawings] Fig. 1 is a front view of the present invention. 2 is a left side perspective view of FIG. 1.
