Abstract
The invention relates to fitness equipment, in particular to a curvilinear guide rail movement mechanism of an elliptical machine capable of adjusting foot motion trails of human body and motion feeling. By changing linear guide rails of the elliptical machine into curvilinear guide rails, the movement mechanism realizes the aim of simply and effectively adjusting the motion trail of pedals of the elliptical machine. Meanwhile, by adjusting the connection method of the pedals and a support bar, the movement mechanism further improves the stress and angle relation between soles and the pedals so as to reduce sport fatigue of foot and sport injury of lower limb. The curvilinear guide rail movement mechanism of the elliptical machine comprises the support bar, pedals, a roller, and the guide rail; when the support bar moves driven by the pedals, the roller arranged at the lower end of the support bar moves back and forth along the guide rail; and the movement mechanism is characterized in that the guide rail adopts partial or total smooth curves.
Description
Technical field
The present invention relates to a kind of body-building apparatus, the particularly a kind of curvilinear guide rail movement mechanism that can adjust human foot's movement locus and recipiomotor elliptical machine.
Background technology
Elliptical machine is a kind of exercise and fitness equipment that progressively comes into vogue, and common elliptical machine is by the orbiting motion of the pedal on two bracing frames about being connected along sub-elliptical, leg exercise such as walking that can the anthropomorphic dummy, the rank of jogging and go up on the stage.In 200610078954.X Chinese patent file, mentioned a kind of elliptical machine that adopts crank and guide rail structure.This elliptical machine can be saved and be taken up room, and enough foot motion strokes are provided, and the motion of foot mode that meets ergonomics in a way is provided simultaneously.
Human body is on walking, the rank of jogging and go up on the stage etc. during motion, the movement locus of foot is to approach oval curve, an important goal of elliptical machine design is exactly the foot motion track of anthropomorphic dummy when carrying out above-mentioned motion as far as possible exactly, simultaneously will be from the movement locus of the pedal of the angle adjustment elliptical machine of kinematics and athletic physiology, make human body when utilizing elliptical machine to take exercise, can either reasonably make each legs and feet portion muscle group obtain taking exercise, reduce injury gained in sports again as far as possible.
Summary of the invention
The present invention is by changing the shaped form guide rail at the linear pattern guide rail with elliptical machine, realized adjusting simply and effectively the purpose of movement locus of the pedal of elliptical machine.Further improve stressed and angular relationship between sole and the pedal by the method for attachment of adjusting pedal and support bar simultaneously, thereby reduced the injury gained in sports of foot motion fatigue and lower limb.
The curvilinear guide rail movement mechanism of elliptical machine of the present invention, comprise support bar, pedal, roller and guide rail, when moving under the drive of support bar at pedal, move the roller front and back on guide rail that are installed in the support bar lower end, it is characterized in that, described guide rail partly or entirely be level and smooth curve.
At different elliptical machine designs, also may adopt the mode of an end by moving before and after roller is on curvilinear guide of crank.
The said smoothed curve of the present invention is meant that the smoothness of this curve makes when human body moves on pedal, the sense of significantly not jolting not is level and smooth on the mathematical meaning.
Fig. 1 has shown the motion that adopts the elliptical machine of linear pattern guide rail.Fig. 3 is the simplified model of Fig. 1, and wherein the relation between the position of the contact A of the position a of pedal and support bar and driving wheel has determined the movement locus of pedal.Fig. 4 shows is the just path curves of pedal under the situation at the middle part of support bar of pedal, and dotted line wherein is in order to the elliptic curve of contrast reference, can see that this curve and elliptic curve are more approaching.When an end of support bar when driving wheel rotates a circle, four positions of A, B, C, D of process correspond to a, b, c, d 4 points on the path curves of pedal.Four line segment Aa, Bb, Cc, Dd in this schematic diagram equate fully.It should be noted that peak is a on this sub-elliptical geometric locus, minimum point is c, and pedal can obtain the power of pedaling of foot downwards in a to c section.
Above-mentioned curve is to obtain when the other end of support bar slides before and after line slideway, and when some part of this guide rail became curve, the path curves of pedal will correspondingly change.
Fig. 5 is the path curves schematic diagram with respect to the pedal of the curvilinear guide among Fig. 2.Can see that with respect to the geometric locus among Fig. 4 the track of ordering near d among this figure has all risen some, the part of ordering the closer to d rises manyly more.It should be noted that: the peak of this curve no longer is a, but after moved on to the M point, this means when motion of foot to the later power of pedaling downwards that just can begin to utilize foot of M point.Correspondingly, the rising that d is ordered means that another pedal can be climbed to than higher d point when a motion of foot during to the very big b point of the power of pedaling of foot downwards.
Can know through comparative analysis, when the peak M on the movement locus and d point relatively near the time, can effectively make the foot of human body pedal power distributions that be optimized downwards, thereby improve the experience of moving.

The specific embodiment
Followingly further specify technical characterictic of the present invention and beneficial effect according to preferred embodiment of the present invention and conjunction with figs..
Fig. 2 is one embodiment of the invention schematic diagram.The left side part of guide rail 1 progressively raises with level and smooth curve, when an end of support bar 6 during around driving wheel 7 rotations, move the roller 2 of other end front and back on guide rail 1, when roller moves to when having raise curved portion, can cause pedal 4 also relatively to raise, being meant relatively for the pedal position under the line slideway situation here.
When roller hoists when mobile, another pedal that is on the guide rail of another side is in the easiest position of exerting oneself.
In the present embodiment, the curved portion of guide rail 1 is tangent the connection with straight line portion, to avoid causing the sense of jolting, influence motion impression.
In the present embodiment, an end of pedal 4 is pivotally attached on the support bar 6 by connecting pivot 5, and the other end is connected with support bar 6 elasticity by spring 3.When motion of foot arrives diverse location, along with the firmly variation of size and angle of sole, spring can be correspondingly compacted or be upspring, thereby the angle of inclination of correspondingly having regulated pedal is adapting to the needs of sole, thereby reaches good ergonomics comfort level.
Fig. 6 is another embodiment of the present invention schematic diagram.In the present embodiment, the two ends of guide rail all are level and smooth curves.
Need to prove that the curvilinear guide that the present invention will protect is not limited to the situation of above-mentioned two embodiment, as long as guide rail is not the linear the scope of protection of the invention that just belongs to.
