It is characterized by the aim of improving.

[0002]

2. Description of the Related Art At present, the transmission system of a general motorcycle or a three-wheeled bicycle and a healthy indoor car is a crank rotation type transmission system and a lever type (lever) transmission system (for example, US Pat. No. 4,574,649). Reference)
And each has its advantages and disadvantages. Speaking of a crank-rotating car, when it is stepped on, it is relatively difficult to overblind (that is, when the crank pedal lowers the apex), it takes a lot of power, and circular stepping is too monotonous. Have. Next, the lever-type vehicle has no blind spots due to the vertical intersection movement, and can freely adjust the height of the stepping movement, so that it has few monotonous defects, but has a disadvantage of loss of inertial force at the vertical transition point.

[0003]

Means for Solving the Problems The inventor of the present invention continued research on the basis thereof, and as a result, in some bicycles (or in healthy indoor vehicles), a transmission system having three kinds of changes was used. The feature is that the pedal type is selected by pulling the control lever, thereby diversifying the maximum efficiency of the march and its movement method, and enhancing the movement effect so that it is not monotonous.

The transmission system of the present invention includes the following: 1. Lever type transmission, moving forward and downward by petaling, stepping up and down, if desired, freely convert and adjust freely, so that humans can walk. In addition, it is very pleasant and fun, and there is no blind spot and it is labor saving.

[0005] 2. Crank rotary transmission, a considerable vehicle speed,
It has the advantage of being advantageous for acceleration.

BRIEF DESCRIPTION OF THE DRAWINGS In order to better understand and understand the structure, functions and features of the present invention, an embodiment will now be described with reference to the drawings.

Referring to the drawings, the most different point of the present invention from a general bicycle or a lever-type bicycle is that the crank 1 of the present invention is provided with a unidirectional bearing 2.
By driving the crankshaft 1 and rotating the main shaft 3 in one fixed direction, the large chainwheel 4
Is fixed to the main shaft 3, rotates in one direction with the main shaft 3, and further drives and rotates the rear wheel shell by the chain 5.

Referring to the drawings, the main shaft 3 is mounted in a main shaft fitting tube 6 of a wheel frame, and the main shaft 3 is freely rotated by a bearing 7 provided thereon. Spindle 3
The chain wheel 4 is combined with a chain wheel fixing plate 9 on one side and fixed to the chain 5, and then combined with the chain 5, and then the rotation of the wheels is driven (same as a general bicycle). One fixed lock plate 10 is provided on the other side, and a convex pillar 11 is provided on the outside of the plate surface on the chain wheel fixed plate 9 and the fixed lock plate 10, respectively, and a square hole 12 and a nut at the center thereof are provided. When the main shaft 3 is rotated by locking the main shaft 3 on both sides of the main shaft 13 and rotating, the chain wheel fixing plate 9 and the fixed lock plate 10 rotate together. Separately, the main shaft 3 is crank-fixed on the main shaft fitting tube 6 by one left turning screw 14L and one right turning screw 14R.

The crank 1 (including the left crank and the right crank) in the present invention is provided with one one-way bearing (Cluteh bearing) 2 in the shaft hole at the joint between the main shaft 3 and the left and right cranks. 1 only has a function of driving and rotating the main shaft 3 in the slightly same direction. Further, one replacement disk 15 and one replacement disk sleeve 16 are inserted into each of the two cranks 1 for each procedure and screwed into the crank. The replacement disk 15 is rotated freely on the crank 1 and the convex disk 11 is also provided on the replacement disk 15;
Further, both axially oriented semicircular concave tanks 17A are provided on the outer diameter of the inner side of the joints of the two cranks 1, and the slide lock plates 18 of the corresponding semicircular concave tanks 17B are also provided on the inner diameter. The steel balls 19 are put in the two semicircular concave tanks 17 corresponding to the two phases, and the slide lock plate 18 is used. Instead, the lock holes 32 are separately provided on the slide lock plate 18 to form the convex columns 1 such as the replacement disk 15, the chain wheel fixed plate 9, the fixed lock plate 10, and the like.
Corresponding to 1; once the combined crank is fitted on the main shaft 3 (ie, on the screw 14 on the main shaft), it is snap-fixed by one washer 20 and a snap ring 21 or the like.

The present invention further includes a sub shaft fitting tube 22 provided below the main shaft fitting tube 6, and a single sub shaft 23 provided therein. The two chain wheels 24 are fixed, the two chain wheels 24 are rotated in synchronism with the countershaft 23, and one end of two chains 25 whose lengths have been calculated are respectively connected to the chain wheels 24.
The two chains 25 are fixed to the top end of a replacement disk 15 on the crank 1 in which the other ends of the two chain wheels 25 are respectively combined. As can be seen in FIG. The alternate disk 15 on both sides of the spindle 3 is connected (as indicated by the continuous axis), and once the left alternate disk 15 rotates in the counterclockwise direction, the right alternate disk 15 is rotated.
Is rotated counterclockwise by the interlocking of the chain 25 and the chain wheel 24 on the countershaft; the reverse is also the same, ie, forming an up-and-down alternating movement.

A separate control for the two crank arms 26 is provided so as to provide two
7 and fixed by pivotal connection of a pivot 28 and each fitted with a humanoid spring 29, thus providing a humanoid spring 29
Has one end approaching the control crank arm 26 and the other end on a lateral receiver 27, said control crank arms 26 retaining the force to compress their top ends inwardly; The top end of the control crank arm 26 is placed on the slide lock plate 18 so as to twist the slide lock plate 18 to effect the lateral (axial) movement. Is connected to a control lever 31 provided at the upper side of the vehicle at the same time, and is connected to a control lever 31. By twisting the control lever 31, the steel wire 30 is indexed, thereby controlling the control cranks on both sides. When the top end of the arm 26 is extended outward or the steel wire 30 is loosened, the force of the humanoid spring 29 is combined to condense the crank arm 26. And to control, to steer the purpose of lateral movement to the right and left by a slide lock plate 18.

According to the bicycle (or indoor healthy vehicle) having the above structure, once the control lever 31 is adjusted to the position 1, the steel wire 30 is strongly pulled upward, and the top ends of the control crank arms 26 on both sides are pulled. And let it extend outward,
The slide lock discs 18 on both cranks 1 are moved laterally outward, respectively, so that the slide lock discs 18 are locked by the lock holes 32 corresponding to the convex pillars 11 of the replacement disk 15, where the left and right cranks 1 are moved. When the pedal is depressed, the slide lock discs 18 and the replacement discs 15 are integrally connected in a timely manner; further petaling causes the chain wheels 24 and the chains 25 also disposed on both sides of the counter shaft 23 to be rotated.
Once the left-hand crank is stepped downward, the right-hand crank naturally rises upward by the relationship linked to the alternation disk 15 to achieve the transmission method of the lever-type alternation.
Thus, when petering, as in the case of a human running method, the vertical petering is relatively quick and there is no blind spot (the component force to be spent is relatively small), so it is relatively labor-saving, and at the time of fatigue,
You can peter at a relatively small angle. If you need to accelerate, it is also a great pleasure while marching at a relatively large angle.

Once the control lever 31 is adjusted to the position 3, the top ends of the two control crank arms 26 in the present invention are contracted by the action force of the humanoid spring 29 while the steel wire 30 is most loosened, and the two slide locks are formed. The disc 18 is moved toward the fixed lock disc 10 and the chain wheel fixed disc 9 respectively (at this time, the slide lock disc is completely separated from the replacement disc). Thus, the slide lock plate 18 is also fixedly connected to the lock hole 32 thereon, the fixed lock plate 10 and the convex pillar 11 on the chain wheel fixed plate 9 integrally with each other. At the time of the coupling operation, the crossing form of 180 degrees is maintained, and after the combination, the bicycle becomes a general crank rotation type transmission bicycle or a healthy indoor vehicle.

Once the control lever 31 is adjusted to the position 2, the two slide lock disks 18 are respectively turned
5 and between the fixed lock disc 10 and the chain wheel fixed disc 9 and rotate the crank 1 to become completely unrelated to the replacement disc 15 or the fixed lock disc 10, the chain wheel fixed disc 9, etc .; , Fixed toes 33
When the left and right cranks 1 are put on the palms, the left and right cranks 1 are independent and can be leveraged or crank-rotated, and the one-way bearing 2 in the crank makes full use of the large chain wheel 4 fixed on the main shaft. Then, it rotates in one direction, drives the rear wheel, and moves forward. However, the stepping method at that stage allows various formulas to be changed, for example: When the feet on both sides step on the same angular position, the circular crank rotations are performed simultaneously at the same time. , Two sides crank alternately, two sides upright petaling, rest one side, leverage petaling on the other side or crank rotary petaling, versatility, diversification We can take advantage.

[0017]

The effect of the invention is a kind of multi-purpose bicycle transmission groove, whose main structure includes a pair of one-way cranks,
It is composed of a set of control units, a set of alternating motion units, and a mechanism such as a chain wheel fixed plate that rotates with a set of main shafts. None, once the slide lock disc and the rotating disc of the moving part are combined, the lever (lever) moves up and down alternately; once the slide lock disc and the chain wheel fixed disc are combined, a general crank rotary motion is made; Then, once the slide lock board holds neutral,
When not combined with any one mechanism, when the pedals on both sides are in the same position, they rotate at the same time, move up and down at the same time, move up and down, two sides can be rotated alternately, two sides can be turned up and down I can do a lever type exercise, one side is resting,
One side rotates, one side rests, and one side plays the role of diversification movement such as leverage movement.
