wheel

51 and 52 is to adopt the same number of teeth, and gear 54 is and sprocket wheel 52 one rotations, and its number of teeth can be identical with the number of teeth of sprocket wheel 52, also can less than or greater than this number of teeth.Idler gear 56 can adopt any suitable number of teeth again, but it again can be for fixed gear 55 turnover because of rotation, so be pinion gear for gear 55.The number of teeth relation of two

gears

54,55 is the same number of teeth in principle, then which kind of number of teeth no matter idler gear 56 adopt, rotary disk 4 and the rotation relationship of spiral arm 3 will keep the direction of rotation relation of speed 1 to 1 on the contrary mutually, the number of teeth of only looking situation gear 54 also may be selected to be less than or greater than the number of teeth of fixed gear 55.When the number of teeth of two

gears

54,55 is identical, gear 54 is when circling, Jie also drives spiral arm 3 just with the transmission of gear 56 and circles with the opposite direction public affairs around gear 55, this will make rotary disk 4 all can keep certain direction when spiral arm 3 rotates to any angle, and make the sporter can keep the direction and the balance of health.If the number of teeth of gear 54 more after a little while, when for example being 1/2 number of teeth of gear 55, then gear 2 weeks of 54 rotations can circle to gear 55 public affairs, if the number of teeth more for a long time, for example 3/2 of gear 55 o'clock, then gear 54 rotations 1 all halfs were that public affairs circle.When both of these case, just can't keep the orientation of rotary disk 4 and sporter and by itself keeping balance, but be not to use as status.

Brake 6 is to be located between the fixed axis 14 of the cardinal extremity of spiral arm 3 and base 1, comprise above-mentioned brake drum 34 and expanding brake block 61, one end of this brake block 61 borrows steady pin 62 to be fixed near the fixed axis 14 of base 1, the other end then is fixed with and brake block 61 is outwards opened and connects airtight at brake drum 34 inner peripheral surfaces and then stop an end of the brake pull bar 63 of brake drum 34 (spiral arm 3), and the other end of brake pull bar 63 then borrows brake rope 64 to draw an end that is connected to the brake handgrip 65 that operationally is articulated on the guard bar 22 through the central straight vertical rod 21 of base 1 and guardrail.

Brake 6 in this embodiment is the patterns that adopt the expanding brake block, but obviously can adopt as can be known known as belt, external tough formula, other forms of brake such as clamp-type replaces.In addition, transmission mechanism 5 is to adopt the sprocket wheel bar group kind of drive in this embodiment, but also can use synchronous belt and synchromesh gear group instead, or gear row, or general V-shape belt and the belt pulley set kind of drive are for it, only, preferably adopt chain, chain wheel mode or synchronous belt, gear mode for making transmission certain and efficient.That shown in Figure 4 is another variation of the utility model, be that gear 55 directly meshes with gear 54, do not establish idler gear 56 between the two, when adopting this kind formation, rotary disk 4 is identical with the direction of rotation of spiral arm 3, usability is relatively poor, but both motions have certain linkage, can not produce indivedual irregular motions as commonly using device.Moreover above-mentioned

bearing resettlement section

32a, 36 all is set as the evagination formula, leaves enough height as the inner space of spiral arm 3, and then these resettlement sections can change the indent formula into, and makes outside the bearing concordant with upper and lower two planes of spiral arm 3 or in its two plane.In addition, two

countershaft

50a, 50b also can change into as coaxial 40 two ends and support into rotatable structure by bearing, and only this moment, sprocket wheel 52 should be separately fixed on countershaft 50a and the 50b with gear 54 and gear 56.

Below use situation and motion thereof to be described as follows with regard to the utility model:

During use, the user steps on rotary disk 4 with both feet, the two hand steered handrails (guard bar) 22 of holding, wherein gently grab brake handgrip 65 on the other hand and simultaneously and after standing firm, the twisting waist to the lower part of the body of both legs so that rotary disk 4 is that middle mind-set one direction (all can forward or backwards with axle 40, the direction that twists waist on the user is decided) rotation, sprocket wheel 51 promptly drives driven sprocket 52 via chain 53 and rotates with same direction, coaxial gear 54 just drives idler gear 56 around fixed gear 55 rotations, so driving spiral arm 3 does and rotary disk 4 reciprocal rotations around axle 14, at this moment, when adopting 1 to 1 as the number of teeth of

gear

54 and 55, then no matter rotary disk 4 all can keep certain orientation to which kind of angle for the rotation of spiral arm 3, for the user, can often keep, so keep the balance and the control of health easily towards positive movement.So continue the twisting waist and can make rotary disk 4, on one side rotation, borrow spiral arm 3 around axle 14 revolution on one side, but and torsional movement.When motion, more and more fast as rotary disk 4 or spiral arm 3 rotating speeds, the user is not easy to catch up with or when keeping balance, then can borrow the operation of brake handgrip 65 to control brake drums 34 and then the speed of spiral arm 3 is slowed down via brake rope 64, therefore the speed of rotary disk 4 also slow down, be the motion of feasible suitable user's oneself responsiveness, even brake drum 34 can be stopped fully, and entire machine is stopped.Make rotary disk 4 to the other direction rotation if the user changes the direction of motion that sways one's hips, spiral arm 3 is also and then towards different direction rotations.

Owing to the utlity model has as above-mentioned formation and action, when the user steps on when moving on rotary disk, spiral arm will be done rotatablely moving synchronously of the certain speed ratio of relevance via transmission mechanism, its speed can be borrowed brake and control arbitrarily by the user again simultaneously, so can get and can the person of being used to do the best and adjust, and more close the locomotory apparatus of practicality and security, can be as commonly using device because rotary disk and spiral arm are not done relevance and random rotation separately, the means of not having control rate again, thereby cause the user to be difficult to routing motion, the control of having no way of again be cannot say for sure balance, the situation of falling easily then.

Below only be illustrated, still can do all modifications and change not violating under the utility model spirit and the following claim with regard to a specific embodiment of the present utility model.
