Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bicycle pedal,

The present invention relates to a bicycle pedal for enhancing driving force for easy detachment. More specifically, the present invention can increase the driving force of a bicycle by generating a forward driving force over a 360-degree range at the time of a user's pedaling, Or separation of the bike pedal is simplified, thereby reducing the risk of accidental injuries.

Generally, a bicycle means a two-wheeled vehicle that can be moved through a wheel that is rotated by human power. The pedal of the bicycle is composed of a pair and is provided on a rotary crankshaft of a drive sprocket connected to a chain by a driven sprocket located on the rear wheel of the bicycle. More specifically, the pedal arm is connected to both ends of a pedal arm coupled to the rotary crankshaft 180 degrees apart.

In other words, by rolling one pedal downward, a forward driving force is transmitted to the rear wheel of the bicycle through the bicycle pedal-pedal arm-drive sprocket-chain-follower sprocket so that the bicycle can advance. At this time, as the pedal arm rotates, the pedal on the opposite side moves upward, and the user repeatedly rotates the both pedals to generate the driving force continuously. Such a conventional pedal can not generate the forward driving force of the bicycle when the pedal rotates upward when the user rolls the pedal and can generate the forward driving force only when the pedal rotates downward. The driving force can not be sufficiently increased, and the exercise effect is also unsatisfactory.

In order to solve such a problem, conventionally, a clip type pedal in which a clip is attached to a pedal and a shoe is pushed into a clip and a pedal and a shoe are tied to each other by hand is developed for a special bicycle such as a player's bicycle, In a more advanced form, a cleat pedal in which a cleat is fixed to the soles of a shoe and a cleat is fitted to a pedal is mainly developed. In the case of using the cleat pedal, the user can solve the above-mentioned problems by safely combining the shoe and the pedal without using the hand, thereby generating the forward driving force. However, since the cleat pedal can sufficiently perform the driving force improvement function, the user must separate the foot from the pedal by rotating the ankle by a certain angle when the bicycle is stopped, so that it is not only troublesome to use but also, The bicycle overturning accident occurs frequently, and there is a fatal problem that life of the bicycle user may be threatened.

Korean Patent Registration No. 10-0996988 (Registered on Nov. 22, 2010) discloses a bicycle pedal which is registered and applied by the applicant and is for easy detachment and driving force improvement. Rather than keeping the shoes upright in an 11-character form, normal bicyclists are actually pedaling to the extent that many people are not in full V-shape, but somehow in front of the shoe. As a result, the rocker having a straight shape contacts the point or the narrow area, causing an uneven wear, and the pedal and the shoe are unexpectedly detached.

FIG. 8 is a cross- Fig. 5 is a view showing a case where the bicycle pedal is rotated upward. As shown in FIG. 7, a bicycle user who wants to rotate the bicycle pedal downward to improve the driving force for easy detachment can downward rotate the bicycle pedal by applying a vertical pressure to the bicycle pedal, as in the case of using a normal bicycle pedal So that the forward driving force can be generated. However, when the bicycle pedal is used, the forward driving force can not be generated when the bicycle pedal is rotated upward, and the forward driving force must be generated by rotating the bicycle pedal on the opposite side. 8, when the bicycle pedal is to be rotated upward, the bicycle user lifts his / her foot while pulling back the bicycle pedal, so that the locking bracket member 300 is fastened to the rocker member 200, An operation of rotating the pedal is performed. That is, since the foot of the bicycle user is fixed to the pedal frame 100 through the lock bracket member 300 and the rocker member 200, both of the bicycle pedals according to the present invention have the forward driving force It is possible to increase the driving force of the bicycle and improve the exercise effect of the bicycle user. The bicycle user lifts the foot fixed to the pedal by pulling backward when it wants to generate the forward driving force over the entire 360 degree range. On the other hand, when the user wants to separate the foot from the pedal, So that it can be separated.
