Description
Technical field
The utility model relates to the exercycle field, mainly is that a kind of pedal is along the exercycle of track reciprocating mechanism.
Background technology
The pedal plate structure of traditional exercycle, as shown in Figure 5: it comprises the vehicle frame 101 that transmission system and resistance system are installed, crank 102, rotation seat 103, pedal connecting rod 104, adjusting rod 105, rocking bar 106 and turning cylinder 107 and the pedal 108 that transmits extraneous torsion moment; When user movement, at first driving crank 102 rotations of sporter, crank 102 drives pedal connecting rod 104 motions by rotation seat 103.Pedal connecting rod 104 is connected with rocking bar by adjusting rod 105 and is connected with turning cylinder 107; Pedal 108 is connected by screw and is fixed on the pedal connecting rod 104, and during user movement, hand drives rocking bar 106,102 motions of shank driving crank.By transmission system, make motion smooth and easy, can coordinate the motion of hand and shank, thereby make body building person reach preferably the purpose of body-building or rehabilitation.
Yet from the angle of ergonomics, in the exercise and rehabilitation of reality, because user's individual difference and health status is different, the user is also different to the strength demand of taking exercise.The pedal of traditional exercycle is fixed, and pedal 108 is certain to the distance of turning cylinder 107, and simultaneously pedal 108 also is certain to rocking bar 106 epimeres, so stride is fixed during user movement.For stride larger crowd or the less crowd of stride, it is impracticable then to seem.For example: when stride the greater was taken exercises at traditional exercycle, centre of body weight held rocking bar 106 epimeres with the motion reach, and pin is along with foot-driven lever moves reciprocatingly.Because sporter's stride is larger, the motion of hand and shank is inharmonious.In whole motion process, the stressed rather than whole sole of forefoot is stressed.Cause like this leg muscle tight tight, the motion persistence is not strong, does not reach the movement effects of expection.When the stride smaller takes exercises at traditional exercycle, move behind the centre of body weight, hold rocking bar 106 epimeres, pin is along with foot-operated panel seat moves back and forth, because sporter's stride is less, the motion of hand and foot also can be inharmonious, in whole motion process, can feel obviously that hand segment distance to the rocking bar 106 is bigger than normal, to lean forward in order to hold the whole health of rocking bar epimere, can cause like this hand muscle and chest, abdominal muscles to be tightened, the health each several part is inharmonious during motion.The adjustment that stride can not vary with each individual does not so reach the movement effects of expection yet.
The utility model content
The purpose of this utility model is just in order to overcome the deficiency of above-mentioned technology, and provide the exercycle of a kind of pedal along the track reciprocating mechanism, mainly solve the motion problem of disharmony that existing exercycle fixedly causes because of pedal, be not only applicable to exercycle, also be applicable to all exercise rehabilitation equipment.The exercycle pedal has increased the comfortableness that the user moves at exercycle along the track reciprocating mechanism.During user movement, the stride cyclically-varying all is significantly improved the harmony of the more smooth and easy health of motion and cardio-pulmonary function.
The utility model solves the technical scheme that its technical problem adopts: this pedal is along the exercycle of track reciprocating mechanism, and it mainly is included as motion provides adjusting rod, turning cylinder, the pedal of the crank of the mainframe of pedestal and transmission kinetic energy, adjustable distance and be connected to the track that the track that is synchronized with the movement is provided for sliding seat on the rotation seat; Crank connection of rotating seat, track is connected with rocking bar by second connecting rod, and turning cylinder is used for fixedly rocking bar, and rocking bar is moved along turning cylinder; Sliding seat is connected with adjusting rod by first connecting rod, and pedal is installed on the sliding seat; Under the driving of input torque, four-bar linkage by track, first connecting rod, second connecting rod and adjusting rod composition, convert the circular motion of crank to pedal reciprocating motion in orbit, thereby change sporter's stride, the change curve of stride is sine curve.
Further, described crank is Contiuum type or three-chip type.
Further, described rotation seat joining rails and crank are equipped with bearing in the rotation seat.
Further, described sliding seat comprises U-shaped sliding seat and roller, and sliding seat moves reciprocatingly roller by the motion of second connecting rod in orbit, makes user's stride be the variation of SIN function curve cycle.
Further, described adjusting rod connects first connecting rod and rocking bar, is used for regulating the distance of first connecting rod and second connecting rod, changes pedal and the angle on ground and sporter's step size.
The effect that the utility model is useful is: the four-bar linkage that the utility model mechanism is comprised of track and connecting rod, from Human Engineering Principle, consider the different of the individual difference of human body and health status, broken through the fixing limitation of traditional exercycle pedal.With pedal orbital motion winding machine periodically-varied stride, make human motion more suitable, more comfortable.Can improve body builder, rehabilitation clients's cardio-pulmonary function and the harmony of health etc.

Operation principle and the course of work:
The exercycle pedal moves back and forth structure along track, adopts Human Engineering Principle, considers the different of human body individual difference and health status.The user is moved along the track reciprocating mechanism at pedal realize that five drive synchronous variable stride, five drive synchronous variable stride change curve is sinusoidal form.And the mode that this structure adopts track and roller to cooperate, under the drive of transmission inertial flywheel system, five drive and can move back and forth in orbit synchronously and again, make motion more smooth and easy comfortable.The user also can select suitable exercise intensity by resistance system.
The user can select by the length of regulating adjusting rod 208 scope of stride change.See also Fig. 1 and Fig. 2, as shown in the figure, adjusting rod is adjusted to ultimate range, and motion of foot is during to the least limit position, and pedal is nearest from rotation seat 203 sizes.Under the drive of inertial flywheel, pedal 211 moves in orbit, when motion large greatest limit position, pedal 211 from rotation seat more away from.Thereby reach the purpose that changes stride.So when the user moved at exercycle, one-period was finished, realize the once change of stride, and step change is from small to large, then from big to small.The step change curve is the SIN function curve.See also simultaneously Fig. 3 and Fig. 4, when adjusting rod was adjusted to minimum range, it was that scope is wide that the scope of foot reciprocating motion does not have adjusting rod to be adjusted to maximum position, and namely adjusting rod 208 is longer, and the excursion of stride is larger.Adjusting rod 208 is shorter, and the step change scope is less.As aerobic exercise, body builder or rehabilitation clients can select to be fit to for the health of oneself motion mode of oneself.Body builder or rehabilitation clients at the volley, hand, chest abdominal muscles and leg muscle can obtain more effective exercise, cardio-pulmonary function also can obtain effectively enhancing, the every function of health reaches the most effective performance.The harmony of health, the continuation of motion is significantly improved, thereby reaches predetermined movement effects.
Should illustrate that at last above example is only in order to illustrating the technical solution of the utility model and not limit therewith, but on using, can extend to other modification, change, use, and think the modification that all are such, change, use, embodiment is all in spirit and scope of the present utility model.
