M305687 Eight, new description: [New technology field] This new type is related to a kind of fitness equipment, in more detail, especially refers to a kind of one-way tightening effect that can produce double feet and increase the span motion effect. Belt electric treadmill (1). [Prior Art] Referring to FIG. 1, a conventional running exercise machine 10 mainly includes a base 11 , a front pole 12 extending upward from the base 11 , and a rocker with two movable shafts disposed on the front pole 12 . 13. An electric motor 14, X fixed in front of the base 11, a frame i 5 at the rear of the base 11, a pulley set 16 disposed at the front of the frame 15, and a rear portion of the frame 15 a crank wheel 17, a pressure wheel set 18 disposed above the machine wood 15, and two pedal sets disposed between the crank wheel set 17 and the rocker 13 for stepping on the human foot. The pulley set 16 has a Large and small pulleys 161, 162 and two belts 163, 164, the crank wheel set 17 has a crank wheel i7i and a crank i72 which is disposed at the center of the crank wheel and whose end is connected with the pedal group 19, the large pulley 161 is coupled with the electric motor 14 by the belt 163, and the small pulley 162 is coupled with the crank wheel m by the belt 164. After the electric motor 14 is started, the pulley set 16 and the crank wheel set 17 can be driven to operate. The pedal group 19 is driven to swing forward and backward, and the human foot can be made to run on the pedal group. Movement. The above-mentioned pressure wheel set 18 does have the effect of running, but there is still a need to improve in use. The front end of the pedal set 19 is pivotally connected to the lower end of the rocker 13 for 4 rear swinging motion, and the rear end is pivotally connected with the crank handle 72. The round back rotation M305687 is '^ a pedal group 19 is restricted by the rocker 13 and the crank i72 movement. The amount of movement of the rear distance is not large, when the human foot steps on the pedal group 19 for running. Only a small running style can be made, and the user can't increase the span to exercise. Therefore, the running fitness of this type can not meet the demand of the manufacturer. ^ [New content]

The upper and lower pressing wheels 322, 332 can just be broadcasted, and the upper and lower pressing wheels 322, 3 32 can be away from the limit position outside the second belt 27. M305687 Referring again to FIGS. 2 and 3, the armrest movement unit 40 includes a handrail frame 4, a rotating shaft 42 disposed above the armrest frame 41, a pulley block 43 drawn below the armrest frame 41, and two axles. A rocker group 44 that is swingable back and forth on the rotating shaft 42 is provided. The armrest frame 41 has two bracket rods 4U respectively disposed at the left and right sides, an electronic instrument panel 412 that is disposed at an upper end of the two bracket rods 411, and two armrests that are connected to the two sides of the electronic instrument panel 412. 413. The rotating shaft 42 is sleeved with two movable sleeves 421. The sleeves 421 are respectively welcomably coupled to the two rocker groups 44. The pulley block 43 has a pulley shaft 431 and two brackets. a locking screw 432 fixed to the outer side of the rod shaft 431 and screwed to both ends of the pulley shaft 431, and a pulley 433 disposed on the pulley shaft 431 for the pedal moving unit 5 () to cross, each rocker group 44 The utility model has a grip 441 which can be gripped by the user's hand t in the vicinity of the sleeve, a rocker cup 442 which can be rotated under the sleeve 421, and a sleeve 442 which can be set at the lower end of the rocker 442 a sliding rod 443 for telescopically moving up and down, and a locking knob 444 fixed to the rocking rod 442 can be locked to the sliding rod 443. The lower end of the rocking rod 442 is convexly disposed at the lower end of the rocker 442. The lower end of the sliding rod 443 is provided with a second ear portion, and the sliding rod 443 can be used for three stages at the shaking point 42 (can be designed by the operator) Reduced number of segments) of different ^ hunting in response to this user can adjust the size of its height Μ stride. The female-pedal motion units 5G each include a stepping lever 51 that is straddles the pulley block ^=the crank wheelset 25 for pivotal linkage, and a pedal that can slide back and forth on the sill of the rocker and the rocker group 44 = a link set 52, a slide on the pedal plate, and 53, and a μ μ » a pair of link sets 54 connected to the pedal set 53 and the M305687 rocker set 44. The long 椁-^ edge of the ^κ γ q θ θ + degree has a predetermined length for the cup 51 ,, and the concave side of the bone movement ^ is provided with a recess 511 for the pedal group 53 to be inserted into the π motion.苴前_ Extravagance into the club group 52 and * mountain, sighing and sighing - brother one lug 512, the first flail, and the two ends of the 52 just squat, the pedal electric 53 is Gutai + and The first ear 445 slide 531 I has a set of 532 which is arranged on the slide rail 511 for sliding back and forth, and a pedal m which is fixed on the slide 531 for the user to step on the foot. a second lug 533 at the front end, a second connecting cup, and 54 includes a main rod 541, a de-sliding slap 541 in front of the main cup 541, and a lockable sub-bar 542 is locked on the main rod 541, and the main rod 541 is pivotally connected to the second ear #446 of the rocker group 44. The auxiliary rod 542 is pivotally connected to the second lug 533 of the pedal unit 53. The sub-rod 542 can be adjusted in three stages (the number of telescoping sections can be designed by the operator) for different lengths f to adjust the distance between the pedal group 53 at the front and rear positions of the step 51, by changing the distance between the pedal 532 and the grip 441. Can adapt to different heights Users. ^ The above is an overview of the structure and shape of the new electric treadmill (1) which can be used for one-way pressing belt; then, the action of the new type and the expected effect can be stated as follows: See Figure 5, 6, when the rocker group 44 is swinging, the lower end of the rocker 442 is interlocked with the pedal 51 by the first link group 52, and the lower end of the slider 443 under the rocker 442 is connected by the second link. The rod group 54 is interlocked with the pedal group 53. The rocker 4 4 2 and the sliding cup 4 4 3 both swing forward and backward with the same rotating shaft 4 2 as the center, and the swing distance between the lower ends of the swing is the same angle. Because the upper and lower position differences are different, the slider 443 drives the pedal group 53 to move a distance of 10 M305687, and the rocker 442 drives the pedal lever 51 to move both the plate group 53 and the pedal lever 51 (four) 'due to the pedal lever—at the same time , step by step (four), "reverse, · and 53 more step-by-step hunting on the pedal 51, the pedal group 53 can achieve the effect of increasing the span of the span. Electric treadmill (a) main t good f know running fitness equipment 1G span is insufficient, 1 main solution is to use the rocker The group 44 is linked with the pedal group 51 by the first link group 52 and the pedal lever 51. The rocker group 44 swings at the same angle with the 4 axis 42 as the center, using the first ST self. 2: The swing amplitude of different heights of the upper and lower sides makes the pedal 51 and the pedal: =3, and has different moving distances. This distance difference allows the pedal group to further slide relative to each other, thereby allowing the user to run. The daily maintenance can achieve the effect of increasing the stride span. The above-mentioned ones are only a preferred embodiment of the present invention, and the scope of this new implementation is limited to the scope of this new type of application. The simple equivalent changes and modifications made by Liganwei and the new description are still within the scope of this new patent.
