Bicycle pedal

The present invention relates to a bicycle pedal.

The conventional bicycle pedal is made of a material such as metal or hard plastic, and has a hollow portion on the tread surface. Among them, the sole is often fitted with a rough surface or a rib structure to increase the slip resistance of the tread surface.

However, the tread surface of this type of structure is very hard, especially when riding on rough and uneven roads. When you step on it, the touch is very poor and it is easy to get tired. The hard material such as metal is easy to be slippery when it is rainy, and it is easy to slip off. , causing danger, on the other hand, the hard material does not have any elasticity, therefore, the pedal can not provide any feedback power of the sole, lifting the pedal is more difficult. On the contrary, in order to achieve better elasticity and use all-soft elastic parts, the force of the heavy-duty step will be greatly absorbed, and the riding speed can not be improved and the pedaling performance is doubled.

In this regard, the industry has developed an improved pedal, which forms a circumferential groove on the outer peripheral surface of the metal pedal, and then uses an outer peripheral surface of the injection molded gel cushion to form an inwardly projecting ring and the groove. The embossing and splicing makes the tread surface a cushion, thereby providing a more comfortable touch. However, this structure is nothing more than a metal pedal outer surface outer layer coated with a cushion pad instead of metal as a tread surface, although with a pedal touch The feeling is softer and more comfortable, but also lacks the carding and fitting effect provided by the metal pedal, and the anti-slip effect is not good. Even if the concave and convex structure is formed on the cushion to seek slippage, the effect is still limited, and the cushion is easy to be long-lasting. Deformed by use. Moreover, the combination of the cushion pad and the pedal is combined with the concave and convex sleeve, and the cushion pad and the pedal are easily separated due to the biasing direction of the pedal, and even the fitting effect between the sole and the pedal is better, and the outer surface of the metal pedal is used. The upper and lower ends of the periphery are formed with a concave-convex structure, and when the soft cushion covering the outer layer is subjected to external force for a long time, the hard pedal concave and convex structure is easily penetrated through the cushion, and the soft and comfortable pedaling provided by the cushion is lost.

Therefore, how to provide a bicycle pedal that has both anti-slip, easy to drive, does not reduce the output power when stepping on, does not reduce the tactile feel, and has the power of feedback and has a labor-saving effect becomes a very important issue.

The main object of the present invention is to provide a bicycle pedal having a soft feeling of being treaded, and when the bicycle is stomped, the shoe can surely grasp the pedal and is not easy to slip, and does not cause the pedaling force loss.

To achieve the above object, the present invention provides a bicycle pedal comprising a frame and a mat.

The frame body is substantially annular and includes an outer ring portion, and the outer ring portion surrounds at least one hollow portion. The outer ring portion of the frame outer ring portion is a first surface and a second surface, respectively. a first imaginary surface defined by a first surface of the outer ring portion farthest from the second surface, and a second imaginary surface defined by the second surface of the outer ring portion farthest from the first surface. The frame further includes a connecting portion for connecting to a bicycle.

The mat is made of a soft material and has a certain elasticity and is embedded in the hollow portion. The mat is opposite to the two sides, a third surface and a fourth surface, and the third surface is opposite to the outer ring portion. a first surface, the fourth surface of the fourth surface facing the outer ring portion is not pressed by the external force, the third surface is convex out of the first imaginary surface, and the fourth surface is protruded from the second surface Outside the imaginary face.

Therefore, the bicycle pedal provided by the present invention can normally provide a soft and elastic treading feeling, and when the force is pressed, the shoes can be fitted and fixed to the outer ring portions of the frame to avoid slipping.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIG. 1 to FIG. 4 , the present invention provides a bicycle pedal including a frame 10 and a mat 20 .

The frame body 10 is preferably made of metal (for example, aluminum alloy or aluminum-magnesium alloy) and is substantially annular and includes an outer ring portion 11 that surrounds at least one hollow portion. The opposite sides of the portion 11 are a first surface 101 and a second surface 102 respectively. The hollow portion extends through the first surface 101 and the second surface 102. The first surface 101 of the outer ring portion 11 is farthest from the second surface 102. A first imaginary plane is defined. The second surface 102 of the outer ring portion 11 defines a second imaginary surface farthest from the first surface 101. The frame 10 further includes a connecting portion 121 for connecting to the connecting portion 121. a bicycle. Preferably, the first surface 101 and the second surface 102 of the outer ring portion 11 are respectively spaced apart from the plurality of tooth portions 111, and the first imaginary surface and the second imaginary surface are respectively provided by the top portions of the tooth portions 111. definition.

The mat 20 is made of a soft material and has a certain elasticity and is embedded in the hollow portion. Preferably, the mat 20 is made of PU material, and the hardness of the material can be based on the rider's weight or riding. The method (for example, the sitting posture or the standing posture) is selected as appropriate; the opposite sides of the mat 20 are a third surface 201 and a fourth surface 202 respectively, and the third surface 201 corresponds to the first surface 101 of the outer ring portion. The fourth surface 202 corresponds to the second surface 102 of the outer ring portion, and is not pressed by an external force. The third surface 201 protrudes beyond the first imaginary surface, and the fourth surface 202 protrudes from the second surface 202. Outside the imaginary face.

Further, the frame 10 further includes a central shaft 12. Preferably, the central shaft 12 is made of a chrome molybdenum steel material having a better strength. The central shaft 12 runs parallel to the first surface 101 and the second surface 102. The outer ring portion 11 further extends outward to form the connecting portion 121. The central shaft 12 divides the area enclosed by the outer ring portion 11 into two hollow portions. The step 20 includes a first step 21 and a second mat 22, the first mat 21 and the second mat 22 are respectively embedded in the two hollow portions and respectively connected to the central shaft 12, preferably, the central shaft 12 is respectively opposite to the two hollow portions At least one supporting frame 122 is extended. The ends of the supporting frames 122 are respectively embedded in the first mat 21 and the second mat 22 to support the first mat 21 and the second mat 22 . On the other hand, a gap 13 is formed between the first step 21 and the second step 22 and the outer ring portion 11 to provide sufficient space for the step 20 to deform. In addition, the first mat 21 and the second mat 22 respectively form a plurality of spaced apart ribs 211 and 221 on the third surface 201 and the fourth surface 202, and each of the ribs 211 and 221 is adjacent to the outer surface. The ring portions 11 are parallel. Preferably, the outer ring portions 11 are substantially square, and each of the ribs 211 and 221 is substantially dome-shaped and parallel with the sides of the outer ring portion 11, whereby the spaced-arranged convex portions are arranged. The ribs 211, 221 can provide a multi-level anti-slip effect, so that the tread pad 20 has a better anti-slip effect.

In particular, the mat 20 and the frame 10 can be combined in the following manner, but are not limited thereto: after the metal frame is molded, the outer ring portion of the frame 10 is reserved at least A notch is formed by inserting the frame into the mold and injecting the soft plastic (rubber) material into the mold, thereby forming the mat 20 so that the mat 20 and the frame 10 are integrally formed.

When in use, as shown in FIG. 3, when the user is in the stage of pulling up the pedal 20 or in a sitting position without applying a large pedaling force (ie, generally easy riding state), the user's sole is mainly stepped on The mat 20 has a soft touch; as shown in FIG. 4, when the user is on an uphill section or in a standing position, a large force is applied to the pedal, and at this time, the mat 20 is caused by The force is slightly deformed, so that the third surface 201 is slightly downward and lower than the first imaginary plane of the frame 10. At this time, the sole of the user can step on the outer ring portion 11 of the frame 10, and the outer ring The part 11 produces a fitting and positioning effect, so that the force of the pedaling is directly and quickly transmitted to the transmission system, and the bicycle is riding faster, but at this time, most of the area of the sole is still in contact with the mat 20, and the pedal is touched. The feeling remains soft, and most importantly, when the force is reduced (for example, when the pedal is lifted), the sole moves upward, and the elastic feedback of the mat 20 gives the sole a force, which makes the sole easier to lift, achieving a labor-saving effect.

Furthermore, the tread pad 20 of the present invention is integrally formed with the frame body 10, so that there is no need to worry about the problem of the tread pad being separated from the frame body during the stepping process, and the tread pad 20 of the present invention is integrally formed and fitted. The hollow portion of the frame body forms a separate area with the outer ring portion 11 of the frame body. Therefore, the stepped seat which is depressed during the stepping force is not overlapped with the outer ring portion of the metal frame body. Maintain the integrity of the mat.

In summary, the bicycle pedal provided by the present invention has the advantages of comfort, slip resistance, good driving force, good feedback, etc., and can save labor and touch regardless of sitting or standing posture, uphill or downhill, stepping on or lifting. It has a good effect and is very effective.
