Description

A kind of ellipse is ridden the rehabilitation structure

Technical field

The utility model relates to a kind of foot-operated structure, is meant a kind of foot-operated rehabilitation structure of ellipse that relates to motion or rehabilitation device class especially.

Background technology

The motion or the rehabilitation device of the foot motion track when generally walking as the simulation human body, as United States Patent (USP) No. 5242343, No. 5383829, No. 5518473, No. 5562574, No. 5577985, No. 5685804, No. 5788609 etc. with reference to case, structure according to these utensils, when the operator steps on its pedal with foot, the movement locus of pedal normally is similar oval in shape, so reaches the foot motion track of simulation human body when walking.

Find according to survey report, human body is when walking, its foot motion track is general most to be to be real oval in shape, but above-mentioned structure with reference to case, the movement locus of its pedal can only be finished similar oval in shape usually, can't really reach the foot motion track of simulation human body when walking.

Summary of the invention

The utility model provides a kind of pedal system of elliptic motion trace, the pedal travel track of this pedal system can really reach oval in shape, this system mainly includes fixed gear plate, reverse fluted disc, main shaft, reversing shaft, long crank, short crank and adjusting device, be combined with the structures that assembly was combined into such as a fixed plate body and a power transmission plate, wherein fixed gear plate cannot not be restricted to rotatablely or is driven in rotation.

By said structure, when the operator moves with foot pedal, the direction of rotation of the short crank that connects with pedal is opposite with the direction of rotation of long crank with causing, therefore can make pedal with real oval-shaped orbiting motion, that is the actual state of the pedal travel track of this system when more walking near human body.

Wherein 1 is fixed gear plate, and 10 is main shaft, and 11 is the fixed gear plate central hole, 2 for reversing fluted disc, and 20 is reversing shaft, and 3 are long crank, 30,31 is hole, and 4 are short crank, and 5 is adjusting device, 50 is the tension force fluted disc, 6 is fixed plate body, and 60 is fixed side, and 61 for welding flange up and down, 7 is the power transmission plate, and 8 is chain.

The specific embodiment

As shown in Figure 1 and Figure 2, this novel main body is made up of with chain 8 or belt etc. fixed gear plate 1, main shaft 10, reverse fluted disc 2, long crank 3, short crank 4, adjusting device 5, fixed plate body 6, power transmission plate 7.Wherein:

Fixed gear plate 1 is to be fixedly arranged in fixed side 60 outer rims, cannot not be rotatable, and fixed gear plate 1 center is provided with a fixed gear plate central hole 11;

Main shaft 10, be placed through fixed gear plate central hole 11, and can rotate freely on fixed gear plate central hole 11 inner edges, do not rotate and can not drive fixed gear plate 1, main shaft 10 is except that being placed through fixed gear plate central hole 11, also be placed through fixed side 60 and be extended down to fixed plate body 6 inner spaces, main shaft 10 connects an intrinsic power transmission plate 7 in fixed plate body 6 inner spaces, when main shaft 10 when fixed gear plate central hole 11 inner edges rotate freely, to be with 7 rotations of priming power transmission plate simultaneously, and power transmission plate 7 can connect a drag devices via power transmission means such as belt or chains 8, when using as the user outside power guiding;

Reverse fluted disc 2, be one to be set up in the disk body that can rotate freely on the reversing shaft 20, reversing the radius of fluted disc 2 and the radial design of fixed gear plate 1 is 1: 2, and reversing shaft 20 fastens respectively in reversing fluted disc 2 and short crank 4, and when reversing fluted disc 2 rotations, can drive reversing shaft 20 and rotate, order about short crank 4 rotations via the rotation of reversing shaft 20 again;

Long crank 3, long crank has been installed with main shaft 10 in the one stomidium hole 30, when long crank 3 when its long crank main shaft hole 30 is done rotation, can be with and draw main shaft 10 and rotate at fixed gear plate central hole 11 and fixed side 60 inner edges, and do not disturb fixed gear plate 1 and fixed side 60, and the rotation of long crank 3 drive main shaft 10 rotates, with 7 rotations of traction power transmission plate, via drag devices, reach the basic effect of motion and rehabilitation, long crank is equipped with reversing shaft 20 in the stomidium hole 31 in addition, and is being reversed between fluted disc 2 and the short crank 4 by reversing shaft 20 folders, and the rotation of reversing shaft 20 is not with any rotation of drawing long crank 3;

Short crank 4 one end interlocks are in reversing shaft 20, and the round end of short crank 4 is owing to reverse the rotation that the rotation of fluted disc 2 drives reversing shaft 20, and then making short crank 4 make rotation around the axle center of reversing shaft 20, the configurable pedal of the other end of short crank 4 is ridden the application of force to make things convenient for the user;

And for example shown in Figure 3, fixed gear plate 1 is connected in series interlock with a chain 8 or belt etc. with reversing between the fluted disc 2, cooperate the tension force fluted disc 50 (as Fig. 1) on the adjusting device 5, can adjust the angle of 3 on short crank 4 and long crank in advance, via the adjustment of this angle, can access the oval radian that is fit to user's figure feature;

Fixed plate body 6, its structure is that two fixed sides 60 cooperate two to weld flange 61 formations one inner space up and down, in order to put power transmission plate 7, and two fixed sides, 60 outer edge surfaces respectively symmetry be installed with fixed gear plate 1 and long crank 3 assemblies such as grade (for diagram concisely, all only the draw structure of a side of Fig. 1, Fig. 2), welding flange 61 up and down can be in welding other device as foot-operated car body up and down respectively, with the bridge that integrates with as the utility model and outer goods.

Again as shown in Figure 4, when following the A clockwise, the user depresses the application of force, to draw long crank 3 along making rotation around long crank main shaft hole 30 by the A clockwise, the rotating band of long crank 3 draws main shaft 10 and follows the A direction to rotate equally with whole chain 8, but when chain 8 whole when shifting by the A direction, because fixed gear plate 1 is fixed, so with chain 8 with the transmission of B direction, and chain 8 will order about reverse fluted disc 2 with the rotation of C clockwise with the transmission of B direction, this shows that the direction of rotation that reverses fluted disc is just opposite with long crank 3;

Please cooperate Fig. 5 and shown in Figure 6 again, because the radius of reverse fluted disc 2 and the radius of fixed gear plate 1 are through being designed to 1: 2, so when long crank 3 rotates an X angle along being made around long crank main shaft hole 30 by the A clockwise, the short crank 4 that then reverses fluted disc 2 drives also opposite spin goes out the X angle, a week is oval radian and step on to revolve.

In sum, of the present utility model simple in structure, be convenient to implement, and the movement locus when having near walking on the spot.
