Bicycle pedal with a self-adjustable retainer for fastening one foot of a rider to a foot-supporting portion

1. Field of the Invention

This invention relates to a bicycle pedal, and more particularly to a bicycle pedal that includes a self-adjustable retainer, which can fasten one foot of a rider to a foot-supporting portion.

2. Description of the Related Art

Referring to FIG. 1 , a first conventional bicycle pedal 10 is shown to include a pedal body 11 , two retaining bands 12 , 13 respectively extending from two opposite sides of the pedal body 11 , and a hook-and-loop band set 14 interconnecting the retaining bands 12 , 13 . As the relative position between the retaining bands 12 , 13 has to be adjusted manually, it is inconvenient to fasten one foot of the rider to the bicycle pedal 10 .

Referring to FIG. 2 , a second conventional bicycle pedal 20 is shown to include a pedal body 21 that is formed with two mushroom-shaped snap fasteners 22 , 23 at two opposite sides thereof, and a retaining band 24 that has first and second end portions 241 , 242 , each of which is formed with a row of positioning holes 2411 , 2421 . Each of the snap fasteners 22 , 23 is inserted into a selected one of the positioning holes 2411 , 2421 . In use, As the positions of the snap fasteners 22 , 23 relative to the positioning holes 2411 , 2421 have to be adjusted manually, it is also inconvenient to fasten one foot of the rider to the pedal body 20 .

The object of this invention is to provide a bicycle pedal that includes a self-adjustable retainer, which can fasten one foot of a rider to a foot-supporting portion.

According to this invention, a bicycle pedal has a foot-supporting portion and a retainer that includes flexible first and second retaining bands, an elongated resilient connecting member, and a flexible sleeve. The first and second retaining bands extend respectively from two opposite sides of the foot-supporting portion. The connecting member has two ends fastened respectively to the first and second retaining bands that engagement band portions of the first and second retaining bands are movable away from each other. The sleeve is disposed around the engagement band portions of the first and second retaining bands. When one foot of a rider is inserted into a space between the sleeve and the foot-supporting portion, the connecting member is stretched automatically to an extent corresponding to the size of the foot so as to clamp the foot between the sleeve and the foot-supporting portion. As such, there is no need to adjust manually the relative position between the first and second retaining bands.

These and other features and advantages of this invention will become apparent in the following detailed description of a preferred embodiment of this invention, with reference to the accompanying drawings, in which:

Referring to FIGS. 3 , 4 , and 5 , the preferred embodiment of a bicycle pedal according to this invention is adapted to support one foot of a rider thereon. The bicycle pedal is shown to include a pedal body 30 , an elongated resilient connecting member 40 , and a flexible sleeve 50 .

The pedal body 30 has a foot-supporting portion 31 and first and second retaining bands 32 , 33 extending respectively and integrally from two opposite sides 311 , 312 of the foot-supporting portion 31 . The first and second retaining bands 32 , 33 , the resilient connecting member 40 , and the sleeve 50 cooperatively constitute a self-adjustable retainer for fastening the foot of the rider to the foot-supporting portion 31 . Each of the first and second retaining bands 32 , 33 is generally U-shaped, and has a fixed end ( 32 F, 33 F) that is formed integrally with the foot-supporting portion 31 , a movable end ( 32 M, 33 M), a main band portion ( 320 M, 330 M) in proximity to the fixed end ( 32 F, 33 F), and an engagement band portion ( 32 E, 33 E) in proximity to the movable end ( 32 M, 33 M).

The resilient connecting member 40 has a first end 41 fastened to the first retaining band 32 , a second end 42 fastened to the second retaining band 33 so that the movable ends ( 32 M, 33 M) of the first and second retaining bands 32 , 33 abut against each other and so that the engagement band portions ( 32 E, 33 E) of the first and second retaining bands 32 , 33 are movable away from each other.

The sleeve 50 is disposed around the engagement band portions ( 32 E, 33 E) of the first and second retaining bands 32 , 33 and the resilient connecting member 40 , and has a first end 51 sleeved around the main band portion ( 320 M) of the first retaining band 32 , and a second end 52 sleeved around the main band portion ( 330 M) of the second retaining band 33 . When the foot is inserted into a space between the sleeve 50 and the foot-supporting portion 31 of the pedal body 30 , the resilient connecting member 40 is stretched automatically to an extent corresponding to the size of the foot so as to clamp the foot between the sleeve 50 and the foot-supporting portion 31 of the pedal body 30 , thereby retaining the foot on the pedal body 30 .

Each of the engagement band portions ( 32 E, 33 E) of the first and second retaining bands 32 , 33 includes two parallel branches ( 320 B, 330 B) that extend respectively from two opposite side portions of the main band portion ( 320 M, 330 M) of a corresponding one of the first and second retaining bands 32 , 33 to the movable end ( 32 M, 33 M) of the corresponding one of the first and second retaining bands 32 , 33 and that are formed respectively with aligned ribs 321 , 331 , which extend toward each other and which are spaced apart from each other and from the main band portion ( 320 M, 330 M) of the corresponding one of the first and second retaining bands 32 , 33 so as to define a T-shaped slot 323 , 333 among the branches ( 320 B, 330 B) and the corresponding main band portion ( 320 M, 330 M). Each of the T-shaped slots 323 , 333 has a longitudinal slot portion 3231 , 3331 that is formed between the ribs 321 , 331 of the corresponding one of the first and second retaining bands 32 , 33 , and a transverse slot portion 3232 , 3332 that is formed between the main band portion ( 320 M, 330 M) and the ribs 321 , 331 of the corresponding one of the first and second retaining bands 32 , 33 and that has a middle portion which is communicated with an end of the longitudinal slot portion 3231 , 3331 . The resilient connecting member 40 is configured as an annular band, and has two opposite side portions 44 , 45 , each of which is sleeved on a corresponding one of the ribs 321 of the first retaining band 32 and a corresponding one of the ribs 331 of the second retaining band 33 . The first end 41 of the resilient connecting member 40 is confined within the transverse slot portion 3232 of the T-shaped slot 323 in the first retaining band 32 . The second end 42 of the resilient connecting member 40 is confined within the transverse slot portion 3332 of the T-shaped slot 333 in the second retaining band 33 . The ribs 321 of the first retaining band 32 are spaced apart from the ribs 331 of the second retaining band 33 . As such, when the foot is inserted into the space between the sleeve 50 and the foot-supporting portion 31 of the pedal body 30 , the ribs 321 of the first retaining band 32 move away from the ribs 331 of the second retaining band 33 from the position shown in FIG. 5 to that shown in FIG. 6 , thereby stretching the resilient connecting member 40 .

The ribs 321 , 331 of the first and second retaining bands 32 , 33 are thinner than the branches ( 320 B, 330 B) of the first and second retaining bands 32 , 33 so as to define a shoulder 322 , 332 between each of the ribs 321 , 331 of the first and second retaining bands 32 , 33 and a corresponding one of the branches ( 320 B, 330 B) of the first and second retaining bands 32 , 33 , thereby confining the resilient connecting member 40 among the shoulders 322 , 332 of the first and second retaining bands 32 , 33 .

To enhance the comfort of the foot, a resilient cushion 60 is attached fixedly to the foot-supporting portion 31 of the pedal body 30 so as to support the foot thereon. The resilient cushion 60 is generally shaped as a plate. The foot-supporting portion 31 of the pedal body 30 has a horizontal top surface 313 that is formed with a depression 3131 for receiving the resilient cushion 60 fittingly.

With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated by the appended claims.
