In addition, the revolving frame f2 and the subframe f3 are fixed to each other by the locking unit 63 to maintain the folded state continuously.

That is, as shown in Figure 5, the main frame (f1) is provided with a locking pin 65, the sub-frame (f3) is provided with a receiving port 67 to which the locking pin 65 is coupled.

Therefore, when the first switching unit 7 is folded and the second switching unit 13 is folded, the engaging pin 65 of the main frame f1 is inserted into the receiving opening 67 of the subframe f3. It can keep you in a non-driving posture.

3, 6, and 7, the handle fixing part 70 may be fixed to the handle 9 by being coupled to the outside of the pivot frame f2 when the non-driving posture is changed.

In more detail, the handle fixing part 70 includes a clamp 71 surrounding the outer circumferential surface of the handle 9; Upper and lower bases 72a and 72b protruding laterally from the clamp 71; Fastening members (86,87) fastened to the upper and lower bases (72a, 72b) to pull the upper and lower bases (72a, 72b) from each other; And a fixing lever pivotally coupled to an upper portion of the fastening members 86 and 87 and being fixed to the pivot frame f2 when the pivot frame f2 is tilted in the direction of the pivot frame f2. (73).

In the handle fixing part having such a structure, the clamp 71 surrounds the outer circumferential surface of the handle 9 by having a cylindrical shape. Both ends of the clamp 71 are separated from each other by a predetermined distance, and the upper and lower bases 72a and 72b protrude laterally from each end.

The fastening members 86 and 87 may be inserted into the upper and lower bases 72a and 72b to pull each other to appropriately adjust the distance between the upper and lower bases 72a and 72b.

The fastening members 86 and 87 are screws 80 which sequentially pass through the upper and lower bases 72a and 72b, and heads which are fastened to the upper portions of the screws 80 and connected to the fixing lever 73. 76 and 77, a mounting table 79 provided on the upper surface of the upper base 72a, through which the screw 80 penetrates, and the eccentric cam 75 of the fixing lever 73 is in rolling contact, and the screw And a nut 82 fastened to the lower portion of the 80 to contact the bottom surface of the lower base 72b.

In the fastening member having such a structure, the heads 76 and 77 are pivotally connected to the eccentric cam 75 of the fixed lever 73.

Therefore, even if the fixing lever 73 rotates clockwise or counterclockwise around the handle 9, the heads 76 and 77 do not rotate together, and as described later, the rotation of the eccentric cam 75 is prevented. Only up and down movement.

The seat 79 is seated on the upper surface of the upper base (72a) and the upper portion is provided with an elastic member 78 having an elastic force. The eccentric cam 75 of the fixed lever 73 is in rolling contact with the upper surface of the elastic member 78.

Therefore, when the fixing lever 73 rotates clockwise or counterclockwise about the handle 9, the eccentric cam 75 contacts the upper surface of the elastic member 78 to prevent noise or vibration. have.

The nut 82 is fastened to the lower portion of the screw 80 and is in contact with the bottom surface of the lower base 72b.

As the nut 82 is tightened or released, the screw 80 moves up and down, and thus the gap between the upper base 72a and the lower base 72b is widened or narrowed.

As a result, the diameter of the clamp 71 can also be adjusted by appropriately adjusting the nut 82, so that the clamp 71 is engageable with handles 9 of various diameters.

On the other hand, the fixing lever 73 is protruded on one side of the plate 88 and the plate 88 and a pair of brackets (84,85) rotatably connected to the pair of fastening members (86,87), respectively And an eccentric cam (75) integrally formed with a pair of brackets (84, 85) and rolling contact with the seating plate (79), and formed on the other side of the plate (88). And a fixture 74 fixed in contact with the outer circumferential surface.

In the fixed lever having such a structure, the pair of brackets 84 and 85 are provided with a pair of eccentric cams 75 at their respective ends. That is, the pair of eccentric cams 75 are spaced apart from each other by a predetermined interval and the cam surface 89 having a constant curvature is formed on the outer circumferential surface.

At this time, the diameter (D) of the eccentric cam 75, that is, the distance connecting the center point of the cam surface 89 and the center point of the head (76, 77) is varied according to the position of the cam surface (89). That is, the diameter (D) of the eccentric cam 75 increases from a point located on the same line as the center line of the plate 88 to a point perpendicular to the center line of the plate 88.

The heads 76 and 77 of the fastening members 86 and 87 are pivotally inserted between the pair of eccentric cams 75.

At this time, the head (76,77) is a crossbar 76 that is pivotally coupled to the pair of eccentric cam (75), and a longitudinal bar 77 protruding from the crossbar 76 and connected to the screw 80 It is composed.

Therefore, when the plate 88 is rotated in the direction of the turning frame f2, the cam surface 89 of the eccentric cam 75 comes into contact with the upper surface of the seating table 79, and the plate 88 is clockwise. As the eccentric cam 75 rotates in the direction, the strength of pressing the seat 79 is gradually increased.

As a result, when the plate 88 is fully folded in the direction of the turning frame f2 and reaches the position where the fastener 74 is coupled to the turning frame f2, the eccentric cam 75 is seated 79 Since the pressing force becomes the greatest state, the plate 88 can be flipped to maintain the fixed state continuously.

The fixture 74 is formed on the other side of the plate 88 and has a concave groove shape. The curvature of the fastener 74 is equal to the curvature of the outer circumferential surface of the swing frame f2.

Therefore, when the plate 88 is flipped in the direction of the turning frame f2, the left and right flow of the handle 9 can be prevented by the fastener 74 contacting the outer circumferential surface of the turning frame f2.

On the other hand, the third switching unit 15 may be provided in the lower portion of the handle frame 47 of the second switching unit 13 can be turned in the rear wheel (5) direction.

The third switching unit 15 is pivotable by being connected to the upper inclined plate 90 disposed to be inclined to the lower portion of the handle frame 47 by a hinge shaft h at the lower portion of the upper inclined plate 90. The lower portion includes a lower inclined plate 92 to which the fork 72 fixing the front wheels 11 is connected.

In addition, the third switching unit 15 having such a structure may overlap the first switching unit 7 and the second switching unit 13 by the front wheel 11 being flipped backward.

On the other hand, the pedestal 100 is provided below the main frame f1. The pedestal 100 has a rectangular ring shape that protrudes downward and has a horizontal shape at the bottom.

Therefore, when the bicycle 1 is switched to the non-driving posture and then standing on the ground, the bicycle 1 can be raised even in the non-driving posture by bringing the pedestal 100 into contact with the ground.

Hereinafter, the handle fixing process of the bicycle according to the embodiment of the present invention will be described in more detail by the accompanying drawings.

As shown in FIGS. 1 to 6, first, the attitude of the bicycle 1 is changed to fix the handle 9 of the bicycle 1.

That is, when the posture of the bicycle 1 is changed from the running posture to the non-driving posture, the turning frame f2 of the first switching unit 7 is rotated clockwise around the hinge pin P.

When the pivot frame f2 rotates clockwise (rear wheel direction; a1), the first link 39 and the second link 43 of the first link member 25 are bent in the inward direction a3. .

Then, the subframe f3 of the second switching unit 13 is rotated in the clockwise direction a2 about the fourth hinge pin P4. As the subframe f3 approaches the first switching unit 7, the second link member 51 is bent in the outward direction a4.

As the second link member 51 is bent, the fourth link 61 is superimposed on the third link 59 to minimize the gap between the subframe f3 and the swing frame f2.

As the subframe f3 rotates clockwise a2 to approach the turning frame f2, the locking pin 67 of the subframe f3 also approaches the receiving opening 65 of the main frame f1. Can be combined.

Accordingly, the first and second switching parts 7 and 13 may be continuously maintained in the non-driving posture by the engagement of the locking pin 67 and the receiving opening 65.

As such, after the first and second switching units 7 and 13 are folded, the third switching unit 15 is folded, and the third switching unit 15 is folded in a state inclined downward.

As described above, the handle 9 is fixed by the handle fixing part 70 after folding all of the first to third switching parts 7, 13, and 15.

The fixing process of the handle 9 will be described in detail. When the plate 88 is rotated in the direction of the turning frame f2, the cam surface 89 of the eccentric cam 75 makes contact with the upper surface of the seat 79. do.

In addition, as the plate 88 rotates in the clockwise direction, the strength of the eccentric cam 75 pressing the upper portion of the seat 79 is gradually increased.

As a result, when the plate 88 is completely flipped to reach the position where the fixture 74 is coupled to the swing frame f2, the state in which the eccentric cam 75 presses the seat 79 is greatest. As a result, the plate 88 may be fixed in a folded state.

At this time, the outer circumferential surface of the revolving frame f2 is accommodated in a concave groove of the fastener 74 to come into contact with the groove.

Therefore, the left and right flow of the handle 9 can be prevented by fixing the handle 9 to the swing frame f2 by the handle fastener 74.

As the left and right flow of the handle 9 is prevented in this way, when the bicycle 1 having a changed posture is moved, only the front wheel 11 is brought into contact with the ground and pushed forward while the rear end of the bicycle 1 is raised. You can move it.

If the handle 9 is not fixed and left and right flow occurs, when the rear of the bicycle 1 is lifted and pushed forward as in the present invention, the handle 9 is swayed left and right and accordingly the front wheel 11 As the bicycle 1 moves forward in the zigzag direction by moving from side to side, the movement may be very inconvenient.
