In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

First, the terms used in the present invention are defined. The up-and-down reciprocating motion (up-and-down reciprocating motion) refers to rotational motion in both upward and downward directions at an angle within 180 degrees. The first and second pedals 1-1-1-2, the first and second indirect transfer wheels 20-1 and 20-2, and the first and second freewheels 30-1 and 30-2, do.

<Embodiment 1: First and second pedal indirect type>

As shown in FIG. 1, the driving system using the freewheel according to the present embodiment is connected to the first and second pedals 1-1 and 1-2, and the first and second pedals 1-1 and 1- The first and second leverage-type drive rods 10-1 and 10-2, the first and second leverage-type drive rods 10-1 and 10- 2, the first and second indirect transfer wheels 20-1 and 20-2, the first and second indirect transfer wheels 20-1 and 20-2 And the first and second levers (10-1, 10-2) are rotated in a reciprocating rotational motion by the first and second levers (10-1, 10-2) 30-1, 30-2), a driving wheel 40 rotating through the reciprocating rotational motion of the first and second free wheels 30-1, 30-2, and a rotational force of the driving wheel 40 to the driving wheels As shown in Fig.

The first and second leverage-type drive rods 10-1 and 10-2 are elongated along the front-rear direction of a traveling product such as a bicycle or a board, and the front end or the rear end of the first and second lever- 2 and the first and second pedals 1-1 and 1-2 are mounted on the opposite sides of the first and second pedals 1-1 and 1-2, The first and second pedals 1-1 and 1-2 are directly coupled to the axes of the first and second indirect transfer wheels 20-1 and 20-2 by moving the wheels 20-1 and 20-2 away from each other. Or the first and second indirect transfer wheels 20-1 and 20-2 can be rotated even by using less force than when the first and second indirect transfer wheels 20-1 and 20-2 are installed close to each other.

Although the first and second pedals 1-1 and 1-2 are shown protruding from the sides of the first and second lever driving rods 10-1 and 10-2 in the drawing, It is also possible that the two lever type driving rods 10-1 and 10-2 serve also as the functions of the first and second pedals.

The first and second indirect transfer wheels 20-1 and 20-2 are supported by the frame of the traveling product so as to be capable of reciprocating upward and downward rotation through an axis, 10-2 so as to be bi-directionally rotated within a predetermined angle by rotation (descending or raising in a certain angle range) of the first and second lever driving rods 10-1, 10-2, Respectively, to the first and second free wheels 30-1 and 30-2.

The first and second indirect transfer wheels 20-1 and 20-2 may be directly connected to the first and second freewheels 30-1 and 30-2 as shown in the figure, It is also possible to indirectly connect via a separate power transmitting member (belt, chain, etc.).

The first freewheel 30-1 is mounted on the frame of the traveling product via the shaft 41. The outer wheel is rotated at a predetermined angle (for example, within 180 degrees) through the first indirect transmission wheel 20-1 At this time, the inner ring is rotated by the first pedal 1-1 to generate a rotational force when the first lever-type driving rod 10-1 is lowered to rotate the driving wheel 40 And maintains the free state when the first leverage type driving rod 10-1 is lifted.

The second freewheel 30-2 is installed such that the inner wheel is installed coaxially with the first freewheel 30-1 and is rotated in a bidirectional manner at an angle (for example, within 180 degrees) through the second indirect transfer wheel 20-2 And the inner ring is rotated by the second pedal 1-2 when the second leverage type driving rod 10-2 is lowered to rotate the driving wheel 40 and to rotate the second leverage type driving rod 10-2 10-2), the free state is maintained.

The drive wheel 40 is preferably installed between the first and second freewheels 30-1 and 30-2 via the first and second free wheels 30-1 and 30-2 and the shaft 41, The first freewheel 30-1 and the second freewheel 30-2 alternately receive rotational force and rotate 360 degrees in the forward direction.

That is, when the first leverage type driving rod 10-1 is lowered, the rotational force of the first freewheel 30-1 is generated (the second free wheel 30-2 is in the free state) so that the driving wheel 40 rotates , The rotational force of the second free wheel 30-2 is generated when the second lever-type driving rod 10-2 is lowered (the first free wheel 30-1 is in the free state) and the driving wheel 40 is rotated , So that the driving wheel 40 is rotated 360 degrees only in the advancing direction.

The rotational force of the driving wheel 40 is transmitted to the driving wheels of the traveling product. For example, as shown in FIG. 1, the driving wheel 40 constitutes a wheel driving wheel 50 axially coupled with the driving wheel, The drive wheel 50 is connected to the chain 51 (the chain can be replaced by various products such as a belt).

The power transmitting means for transmitting the rotational force of the driving wheel 40 to the driving wheels may be configured as follows.

As shown in FIGS. 2 and 6, the power transmitting means includes a first power transmitting body 52 that is directly or indirectly connected to the driving wheel 40 (indicated by an indirect connection by a chain in the figure) A second power transmission body 53 having an outer diameter larger than that of the power transmission body 52 and formed coaxially with the first power transmission body 52 and a second power transmission body 53 having an outer diameter smaller than that of the second power transmission body 53, The third power transmission body 54 and the third power transmission body 54 are larger in outer diameter than the third power transmission body 54 and the wheel drive wheel 50, And a fourth power transmitting body 55 formed coaxially with the first power transmitting body 55 and rotating the wheel driving wheel 50. [ Of course, the power transmission means is not limited to a multi-stage, but may be a single stage, of course, and may be of two or more stages.

The power transmission members may be various products such as a pulley, a gear, and a chain wheel, but the fourth power transmission body 55 or the wheel driving wheel 50 is preferably a free wheel.

In the present invention, a combination of the above-described power transmission means and a ready-made derailleur can be used.

In the figure, reference numeral 2 denotes a frame of a traveling product (bicycle), and 3 denotes a driving wheel.

Further, the first and second lever driving rods 10-1 and 10-2 are connected through the interlocking member 60 (shown in FIG. 1) so that the upward and downward movements smoothly interlock with each other.

The interlocking member 60 can be used for various products such as a wire, a belt, a chain, and a link, and both longitudinal sides thereof are fixed to the first and second lever driving rods 10-1 and 10-2, The second lever-type driving rod 10-1 is connected to the second lever-type driving rod 10-1 through the interlocking member 60 when the first lever-type driving rod 10-1 is lowered by the user's pressing force, The first leverage type driving rod 10-1 rises through the interlocking member 60 when the second leverage type driving rod 10-2 is lowered, The leverage type drive rods 10-1 and 10-2 make the use of the first and second pedals 1-1 and 1-2 very convenient by setting the first and second pedals 1-1 and 1-2 to positions where the first and second pedals 1-1 and 1-2 can be easily pushed by the user.

According to the present embodiment, when the user presses the pedals 1-1 and 1-2 one by one while raising his / her feet on the first and second pedals 1-1 and 1-2, for example, if the first pedal 1-1 is first pressed, The lever drive rod 10-1 is lowered (rotated clockwise in FIG. 1) together with the axis of the first indirect delivery wheel 20-1 (the second lever drive rod 10-2 is rotated in the clockwise direction in FIG. 1) 60).

The first indirect transmission wheel 20-1 is rotated by the descent of the first leverage type driving rod 10-1 and the first free wheel 30-1 is rotated by the rotation of the first indirect transmission wheel 20-1, ).

More specifically, the rotation of the outer ring of the first freewheel 30-1 is transmitted as the rotation of the inner ring. The outer wheel of the first freewheel 30-1 is not rotated 360 degrees but is reciprocated in the vertical direction within 180 degrees. The inner wheel rotates the driving wheel 40 by rotating the shaft 41 by the outer ring.

The rotation of the driving wheel 40 is transmitted to the wheel side driving wheel 50 so that the driving wheel 3 rotates in the forward direction.

In this process, the second leverage drive rod 10-2 rises and the second indirect delivery wheel 20-2 rotates in the opposite direction to the first indirect delivery wheel 20-1, but the second freewheel 30- 2 is in the free state, the driving wheel 40 is rotated by the first freewheel 30-1 only.

On the contrary, when the second pedal 1-2 is depressed, the second leverage drive rod 10-2 is lowered and the second indirect transfer wheel 20-2 is reciprocally rotated in the vertical direction, and this rotation is transmitted to the second freewheel 30 -2) -axis 41 -Drive wheel 40 -Wheel side drive wheel 50 -Drive wheel 3

At this time, the first freewheel 30-1 maintains the free state and the drive wheel 3 rotates only by the second freewheel 30-2.

Accordingly, when the first pedal 1-1 and the second pedal 1-2 are alternately repeated, the driving wheel 3 continuously rotates in the forward direction.

In the present embodiment, the first and second lever driving rods 10-1 and 10-2, the first and second indirect transmission wheels 20-1 and 20-2, the first and second free wheels 30-1 and 30-2 -2, the driving wheel 40, and the like are not limited to those shown in the drawings and can be variously changed. For example, as shown in FIG. 5, the first and second lever driving rods 10-1 and 10-2 are disposed at the front side, and the driving wheel 40 is connected to the first and second free wheels 30-1 and 30- 2, but at one end thereof.

As shown in FIG. 3, the first and second lever-like driving rods 10-3 and 10-3 are provided in front of the first and second lever-type driving rods 10-1 and 10-2, 10-4, the first and second auxiliary pedals 1-3 and 1-4, and the first and second auxiliary indirect transmission wheels 20-3 and 20-4.
