DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a bicycle pedal according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a bicycle pedal 100 according to an embodiment of the present invention includes a pedal shaft 110 connected to a pedal crank, a pedal platform 120 supporting a foot of the operator, And a pivot joint 130 for coupling the pedal shaft 120 to the pedal shaft 110.

At this time, the pedal shaft 110 is inserted into the pedal platform 120 in the same manner as in the normal case, and the pedal platform 120 is rotated in the direction of 360 ° (in the first direction) forward or backward . Thus, the foot of the operator can maintain the same posture while the pedal is rotated.

Particularly, in the present invention, the end of the pedal shaft 110 is connected to the pivotal coupling 130, and the pivotal coupling 130 is rotated clockwise or counterclockwise when looking at the horizontal plane of the pedal platform 120 Direction. Therefore, as shown in FIGS. 6 to 8, the posture of the pedal platform 120 is rotated (rotated in the second direction) within a predetermined angle when the vehicle is running in a curve.

As described above, according to the present invention, since the pedal platform 120 rotates in the left and right direction at a predetermined angle (second direction rotation) with the outer end of the pedal shaft 110 as the origin of rotation, the performance in the straight running is not reduced, The pedal can be applied more effectively when driving.

Further, since the posture of the pedal platform 120 is also adjusted so as to match the foot posture of the operator at the time of corner driving as described above, the present invention prevents the foot of the operator from being injured and improves the corner driving ability by making the bicycle and the operator united.

More specifically, the pedal shaft 110 rotatably supports the pedal platform 120 in a state where one end is connected to the bicycle body (specifically, connected to the pedal crank). Typically, a spindle is used do.

As shown in FIG. 3A, for example, the pedal shaft 110 is shaped to have a smaller diameter toward the outer side because the outer side is the center of rotation.

At this time, the pedal shaft 110 has an inner engaging portion 111 formed at an inner side near the bicycle body. The inner engaging portion 111 is formed of, for example, a coupling having a female thread and is connected to the crankshaft of the bicycle.

Further, the pedal shaft 110 has an outer engaging portion 112 formed on the outer side of the bicycle body. The outer coupling portion 112 is connected to the rotation coupling hole 130, and for example, a fitting projection is used.

In addition, a tapered spring coupling portion 113 is provided at a portion of the pedal shaft 110 that is spaced outwardly from the inner coupling portion 111. The spring coupling member 113 serves to fix the posture return springs S-F and S-B to be described later.

3 (b) illustrates an example in which a sphere type pivot joint 130 'is integrally connected to the pedal shaft 110. The pedal shaft 110 is connected to the cylindrical pivot joint 130, Which is different from that of the first embodiment. The description will be described in detail below.

Next, as shown in FIG. 4, the pedal platform 120 is a portion of the bicycle operator's feet, and the operator steps the pedal platform 120 in a horizontal plane (i.e., a dorsal surface) to rotate the pedal crank.

The pedal platform 120 includes a stationary type fixed to the shoe of the operator and a non-stationary type that is not fixed. In the case of the non-stationary type, the pedal platform 120 protrudes the locking pin to prevent the shoe from slipping.

On the other hand, the pedal platform 120 is fitted with the pedal shaft 110. In general, the pedal platform 120 is fitted on the pedal platform 120 starting from the inner side center portion of the pedal platform 120 toward the outside. However, the present invention can be applied to various other methods.

The pedal platform 120 is formed with a posture adjusting movement path 121 that allows the pedal platform 120 to be rotated in the second direction with the outer end of the pedal shaft 110 as a rotation origin.

The posture adjusting and moving passage 121 is an empty space formed in a path (or range) in which the pedal platform 120 moves clockwise or counterclockwise with respect to the pedal shaft 110 at a predetermined angle.

4, the posture adjusting passage 121 may be formed in a part of the inner side surface of the pedal platform 120, or may be formed in the center of the pedal platform 120, Constitute a moving passage.

At this time, the entire shape of the posture adjusting and moving path 121 is shaped like a fan in correspondence with the movement path of the pedal platform 120, thereby guiding the movement of the pedal platform 120 and changing the excessive posture of the pedal platform 120 .

4, when the present invention is applied to a stationary pedal, the pedal platform 120 may further include a fixing portion (not shown) for fixing the footwear 120 along the rim.

Accordingly, in the case of the fixed pedal, the posture adjusting and moving passage 121 may be formed in the fixing portion as necessary. This makes it possible to apply the present invention to both fixed pedals and non-fixed pedals.

It is preferable that the pedal platform 120 is formed by vertically assembling the upper half platform 120a and the lower half platform 120b so as to facilitate the manufacture of the pedal platform 120. [

Therefore, the pedal shaft 110 and the pivot joint 130 are disposed between the upper and lower half platforms 120a and 120b, respectively, and then the upper half platform 120a and the lower half platform 120b Let them assemble together.

Since the pivotal coupling 130 is disposed in the pedal platform 120, the pivotal coupling holes 130a and 122b are formed on the inner side surfaces of the upper half platform 120a and the lower half platform 120b, respectively, (130) to be assembled.

For example, when a cylindrical pivot is used as the pivot 130, the upper half platform 120a is formed with an upper assembly groove 122a having a circular section and a depth corresponding to half the height of the cylinder, And similarly, the lower mounting platform 122b is formed in the lower half platform 120b.

Therefore, the upper and lower portions of the pivotal coupling pivot 130 are fitted into the upper fitting groove 122a and the lower fitting groove 122b, respectively, so that the pivot coupling fitting 130 To rotate in the second direction.

The pivot joint 130 then serves as a pivot for the pedal shaft 120 to pivotally couple the pedal shaft 120 to the pedal shaft 120. The pedal shaft 120 is rotatable within the pedal platform 120 .

The pedal shaft 110 is coupled to the pedal shaft 120 so that the pedal shaft 110 is coupled to the pedal shaft 120. The pedal shaft 110 is connected to the pedal shaft 120, Is rotated 360 ° in the 'first direction'.

Particularly, the pivot joint 130 is assembled to rotate clockwise or counterclockwise when looking at the horizontal response of the pedal platform 120, so that the pedal platform is rotated at a certain angle in the 'second direction'.

Accordingly, the pedal platform 120 is rotated in the left and right direction within a certain angle range with the outer end of the pedal shaft 110 as the turning origin during the curve running, and the posture thereof is adjusted.

However, the pivot joint 130 of the present invention can be used in any manner as long as it can rotate the pedal platform 120 in the second direction, and the pivot joint 130, which is typically applicable, Respectively.

For example, as shown in FIG. 5, the pivot coupling hole 130 has a cylindrical shape whose height is thinner than the thickness of the pedal platform 120, so that the pivot platform 120 can be pivoted in a circumferential direction It plays a role.

Of course, the height of the cylindrical pivot joint 130 is somewhat high, so that the upper and lower surfaces of the pivot joint 130 do not have any particular limitation such as being exposed to the outside through the upper and lower surfaces of the pedal platform 120.

The fitting hole 131 is formed in the pivot shaft 130 so that the pedal shaft 110 is inserted from the side of the pivot shaft 130. The outer engaging portion 112 at the outer end of the pedal shaft 110 is inserted into the pivot hole (Not shown).

As described above, the pedal shaft 110, which serves as a rotary shaft, is rotatably coupled to the fitting hole 131 of the rotary coupling member 130 so that the pedal platform 120 is rotated in the first direction. At the same time, the pivotal coupling 130 is rotated in the circumferential direction so that the pedal platform 120 is rotated in the second direction.

If the first and second directions are rotatable, there is no particular limitation on the type of the rotation coupling member 130. Thus, as shown in FIG. 3 (b), a spherical body integrally provided at the end of the pedal shaft 110 A ball may be used as the rotation coupling member 130 '.

When a ball-shaped pivot joint 130 'is integrally formed at the outer end of the pedal shaft 110, a pedal platform 120 is provided with a spherical fitting groove (not shown), and a ball- 130 ') in the spherical assembling groove to engage with the ball joint.

Accordingly, when the end portion of the pedal shaft 110 is coupled to the pedal platform 120 through the pivotal coupling 130 'in a ball joint manner, the pedal platform 120 rotates in the first direction, It becomes possible to rotate.

1 and 2, the posture return springs S-F and S-B are respectively provided on the left and right sides of the pedal shaft 110 with reference to the posture return springs S-F and S-B.

One end of each of the posture return springs S-F and S-B is supported by a pedal shaft 110 whose posture is fixed (rotatable), and the other end thereof exerts an elastic force on the pedal platform 120 whose posture is changed.

Specifically, a forward-side posture return spring SF is inserted into the posture adjusting and moving path 121 between the pedal shaft 110 and the front side of the pedal platform 120, and the pedal shaft 110 and the pedal platform 120 The posture adjusting return spring SB is inserted into the posture adjusting and moving path 121 between the rear sides of the rear side posture restricting passage 121. [

In addition, the pedal platform 120 is formed with a latching protrusion 121a, a pedal shaft 110 is formed with a tapered spring coupling 113, and the position return spring SF, Respectively.

Accordingly, the pedal platform 120, which has changed its posture during the curved traveling, can be restrained by the posture return springs SF and SB which exert an elastic force on both sides of the pedal shaft 110 when the pedal platform 120 is straight- A return to the center is made.

According to the above-described configuration, the present invention maintains the horizontal position without changing the attitude of the pedal in the straight line section while the bicycle is traveling, while the posture of the left and right pedals is changed to a certain angle at the curved section .

For example, as shown in FIG. 6, when the bicycle is traveling in a curve section, the left pedal 120-L approaches the bicycle body at the rear portion with the pedal shaft 110 as a boundary, and the right pedal 120- The posture is changed so that the front portion is closer to the bicycle body with the pedal shaft 110 as a boundary.

That is, the left pedal platform 120 and the right pedal platform 120 are also moved counterclockwise by a predetermined angle to change their posture when the vehicle is traveling in a counterclockwise or curved section. The posture change of the pedal platform 120 is made naturally as the force is transmitted.

Therefore, it is possible to apply force in the optimum direction against the centrifugal force which is supposed to be pushed outwardly when the bicycle is running, and also to direct the force applied to the pedal platform 120 toward the inside looking toward the bicycle body Thereby transmitting the force to the pedal more effectively when traveling in a curve.

In addition, since the posture of the pedal platform 120 is adjusted so as to match the foot of the operator at the time of running the curve, the foot of the operator is prevented from being injured, and the bike and the operator are integrated to improve the cornering ability.

The posture change of the pedal platform 120 is a clockwise change and a counterclockwise change. The counterclockwise posture change can be seen in more detail in FIG. 7, and the clockwise posture change can be found in detail in FIG. .

Of course, in the straight line section, the pedal platform 120 maintains its center without any deviation with respect to the pedal shaft 110, and such restoration is automatically performed by the above-described posture return springs SF and SB .

The specific embodiments of the present invention have been described above. It is to be understood, however, that the scope and spirit of the present invention is not limited to these specific embodiments, and that various modifications and changes may be made without departing from the spirit of the present invention. If you have, you will understand.

Therefore, it should be understood that the above-described embodiments are provided so that those skilled in the art can fully understand the scope of the present invention.
