Bicycle pedal having two surfaces for coupling to a bicycle shoe

A bicycle pedal which includes a pedal base, two fixed locating plates fixedly and reversely secured to the pedal base, two movable locating plates turned about respective locating bolts on the pedal base to act against the fixed locating plate for the coupling of the sole of a bicycle shoe, two stop plates moved in respective sliding slots on the pedal base, two springs respectively turned about the locating bolts and abutted against the stop plates and hung on the movable locating plates to force the movable locating plates toward the fixed locating plates, two socket head screws respectively threaded into respective countersunk screw holes on the pedal base and respective screw holes on the stop plates and turned to move the stop plates relative to the springs in adjusting the spring force of the springs.

BACKGROUND AND SUMMARY OF THE INVENTION 
The present invention relates to bicycle pedals, and relates more 
specifically to such a bicycle pedal designed for the coupling of the sole 
of a bicycle shoe. 
FIG. 1 shows a prior art bicycle pedal designed for the coupling of the 
sole of a bicycle shoe. This structure of bicycle pedal comprises two 
fixed locating plates and two movable locating plates for the coupling of 
the sole of a bicycle shoe. The movable locating plates are respectively 
forced toward the fixed locating plates by springs. The spring force of 
each spring is controlled by a respective stop plate and a respective 
screw bolt. This structure of bicycle pedal is complicated, and needs much 
installation space. When adjusting the spring force, the stop plate tends 
to fall out of place, causing the springs unable to be forced into place. 
The present invention has been accomplished to provide a bicycle pedal 
which eliminates the aforesaid drawbacks. It is one object of the present 
invention to provide a bicycle pedal which is easy to assemble. It is 
another object of the present invention to provide a bicycle pedal which 
needs less installation space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIGS. 2, 3, and 4, a bicycle pedal in accordance with the 
present invention is generally comprised of a pedal base 2, two stop 
plates 3, and two springs 4. The stop plates 3 and the springs 4 are 
symmetrically fastened to the pedal base 2 in reversed directions. 
The pedal base 2 comprises an outer thread 21 at one end for mounting, and 
a coupling block 22 at an opposite end. Two fixed locating plates 5 are 
fastened to two opposite sides of the coupling block 22 by countersunk 
screws 51. Each of the fixed locating plates 5 has a coupling flange 52 at 
one end. The coupling block 22 has two sliding slots 221 near two opposite 
ends, and two horizontal countersunk screw holes 222 at two opposite ends. 
The stop plates 3 are respectively and reversely mounted within the 
sliding slots 221 of the locating block 22 of the pedal base 2, each 
having a top projecting portion 31 moved in one sliding slot 221, and a 
screw hole 32 in alignment with one countersunk screw hole 222 of the 
coupling block 22 of the pedal base 2. Two socket head screws 6 are 
respectively threaded into the countersunk screw holes 222 of the coupling 
block 22 of the pedal base 2 and the screw holes 32 of the stop plates 3. 
The springs 4 are respectively mounted within two movable locating plates 
7 and coupled to two opposite ends of the coupling block 22 of the pedal 
base 2 in reversed directions by two locating bolts 8. Each of the movable 
locating plates 7 has two eyed lugs 71 bridging over one sliding slot 221 
of the coupling block 22 of the pedal base. The locating bolts 8 are 
respectively inserted through the eyed lugs 71 of the movable locating 
plates 7 and coiled opposite ends of springs 4, and then fixed to the 
transverse end wall 223 of the coupling block 22 of the pedal base 2. Each 
of the springs 4 has a middle retaining portion 41 hung on one movable 
locating plate 7 to force it toward the coupling flange 52 of the 
corresponding fixed locating plate 5. When assembled, the springs 4 are 
respectively abutted against the stop plates 3. By turning the socket head 
screws 6 to move the stop plates 3 inwards or outwards, the spring force 
of each spring 4 is relatively adjusted.
