Abstract

The utility model relates to a horizontal pedal for bicycle. When the utility model is adopted, the inner plate, the outer plate or the pedal skin of the pedal is made into eccentricity type; the centers of the two rubber axle holes of the inner plate and the outer plate are not aligned with the centers of the axle holes of the left pedal and the right pedal; or the pedal skin is made from the rubber which is added with a balancing weight block. The barycenter of the pedals are not coincident with the centers of the left pedal axle and the right pedal axle. By adopting the method of the utility model, the pedals can always maintain horizontality, so a user is easy to get on the bicycle.

Description

Horizontal pedal for bicycles

The utility model relates to a kind of bicycle pedal, is made up of left and right pedal axle (1), rubber axle (2), nut (3), inner panel (4), footstep leather (5), pedal tube (6), cup (7), pedal retaining (8), outside plate (9), pedal nut (10), pedal packing ring (11), pedal steel ball (12).

For a long time, multi-form bicycle pedal adopts the center symmetrical expression always, and the center of gravity of this old-fashioned pedal overlaps with left and right pedal axle center, it is a neutral equilibrium, and under a lot of situations, the pedal plane can not remain on level attitude, sometimes be in vertical direction, be not easy to get on the bus.

The utility model can overcome above-mentioned weak point, and a kind of horizontal pedal product is provided.

The purpose of this utility model can reach (pedal structure such as Fig. 1,2) is made of the horizontal pedal (4) two rubber axles of inner panel (2), two nuts (3), two footstep leathers (5) of the outside plate (9) of a centering type, a centering type core by following measure.Dress up a complete pedal, also will use the original left and right pedal axle of old-fashioned pedal (1), pedal tube (5), cup (7), pedal nut (10), pedal packing ring (11), pedal steel ball (12).Footstep leather (5) in the horizontal pedal core, rubber axle (2), nut (3) be also available uses on the old-fashioned pedal original.

In order to make the horizontal pedal be applicable to various bicycle, adopt original part simultaneously as much as possible, the shape and size of centering type outside plate (9) and inner panel (4) can be determined according to actual conditions.For example: a kind of form of the present utility model is: centering type inner panel (4) and outside plate (9) do be in line with the smooth bonded assembly broad-mouthed receptacle for holding liquid of circular arc shape form referring to Fig. 3, Fig. 4, Fig. 5, Fig. 6.

After the assembling, two the rubber axis hole centers on pedal outside plate and the inner panel and the center of left and right pedal axle be in-line not, and the center of gravity of pedal does not overlap with left and right pedal axle center.Referring to Fig. 1.

Among Fig. 1, A represents the center of left and right pedal axle (1).

B represents the equivalent center of gravity of footstep leather (5), rubber axle (2), nut (3).

C represents the equivalent center of gravity of outside plate (9), inner panel (4).

D represents the equivalent eccentric throw of outside plate (9), inner panel (4).

E represents the equivalent eccentric throw of footstep leather (5), rubber axle (2), nut (3).

Owing to have eccentric throw D and E, so the center of gravity of horizontal pedal does not overlap with the center of left and right crank shaft (1). So under the gravity effect, the pedal plane is horizontal all the time.

The purpose of this utility model can also reach (referring to Fig. 7) by following measure: use interior plate and the outside plate of the Central Symmetric of old-fashioned pedal, and two footstep leathers are made eccentric formula. For example, when making footstep leather with rubber, close into the counterweight piece in its dough model, during assembling, allow the one side of pedal belt counterweight piece at same. Under the gravity effect, make the pedal plane remain on horizontal level.

The utility model has the following advantages compared to existing technology: it goes without doing, and too big change just can make pedal remain on horizontal level, and the cyclist is got on the bus conveniently.

The figure face of accompanying drawing is described as follows:

Fig. 1, Fig. 2: horizontal pedal. Fig. 2 is the top view of Fig. 1.

Fig. 3, Fig. 4: eccentric formula outside plate embodiment. Fig. 4 is the top view of Fig. 3.

Fig. 5, Fig. 6: plate embodiment in the eccentric formula. Fig. 6 is the top view of Fig. 5.

Fig. 7: pedal adds the schematic diagram (13 expression counterweight pieces among the figure) of counterweight piece.

Further narrate the utility model below in conjunction with (Fig. 3,4,5,6) embodiment: inner panel and outside plate are made centering type, and material is the deep draw cold rolled thin steel sheet

(B－1－GB708－65)/(08A1－Ⅲ－F－YB215－65)

Sunk part can with the welding method make, also can be made into a detachable recessed broad-mouthed receptacle for holding liquid and assemble up.The form of two apertures on outside plate and the inner panel and size can change according to the mating parts characteristic.

Concrete Details sees Fig. 3, Fig. 4, Fig. 5, Fig. 6.

Claims

1, bicycle horizontal pedal is made up of left and right pedal axle (1), rubber axle (2), nut (3), inner panel (4), footstep leather (5), pedal tube (6) cup (7), pedal retaining (8), outside plate (9), pedal nut (10) pedal packing ring (11), pedal steel ball (12);

Feature of the present utility model is that inner panel, outside plate or footstep leather are made centering type, makes pedal remain horizontality.

2,, it is characterized in that the center of gravity of pedal does not overlap with left and right pedal axle center according to the pedal of claim 1.

3,, it is characterized in that not in-line of two rubber axis hole centers on outside plate and the inner panel and left and right pedal axis hole center according to claim 1,2 pedal.

4, according to claim 1,2 pedal, it is characterized in that footstep leather is that the rubber that is added with clump weight is made, and is perhaps made by metallic material.
