Bicycle pedals

The invention relates to a bicycle pedal and in particular to a pedal that can be coupled to the sole of a bicycle shoe.

2Q Fig. 4 shows a conventional bicycle pedal designed to hold the sole of a bicycle shoe. This structure of the bicycle pedals comprises two fixed holding plates and two loose holding plates for coupling the sole of a bicycle shoe. The movable holding plates are each pressed towards the fixed holding plates by springs. The spring force of each spring is controlled by a corresponding stop plate and by a corresponding screw bolt. This structure of the bicycle pedals is complicated and takes up a large amount of space.

OQ installation space. When adjusting the spring force, the stop plate tends to fall out, making it impossible to press the springs into place.

gr This is where the invention aims to remedy the situation. The object of the invention is therefore to provide a bicycle pedal of the type mentioned at the beginning,

^ which, while eliminating the aforementioned disadvantages, is simple in design and easy to assemble. Furthermore, the bicycle pedals should require a small installation volume.

This object is achieved according to the invention by the features specified in the characterizing part of the main claim. With regard to preferred embodiments, reference is made to the features of the subclaims.

¹ ^ Further advantages, details and essential features of the invention emerge from the following description of a preferred embodiment of the invention with reference to the accompanying drawings. In particular:

As shown in Figs. 1, 2 and 3, the bicycle pedal according to the invention generally comprises a pedal base 2, two stop plates 3 and two springs 4. The stop plates 3 and the springs 4 are symmetrically attached to the pedal base 2 in opposite directions.

The pedal base 2 has an external thread 21 at one end for fastening and a coupling block 22 at the opposite end. Two fixed holding plates 5 are held on the two opposite sides of the coupling block 22 via countersunk screws 51. Each of the fixed holding plates 5 carries a coupling flange 52 at one

End. The coupling block 22 has two sliding slots 221 near the opposite ends and two horizontal countersunk threaded holes 222 on opposite ends. The stop plates 3 are each held inverted within the sliding slots 221 of the coupling block 22 of the pedal base 2, with an upper projecting part 31 being slidable in one of the sliding slots 221, while a threaded hole 32 is aligned with a countersunk threaded hole 222 of the coupling block 22 of the pedal base 2. Two cap screws 6 are each screwed into the threaded holes 222 of the coupling block 22 of the pedal base 2 and into the threaded holes 32 of the stop plates 3. The springs 4 are each mounted inside the two movable holding plates 7 and fastened to the two opposite ends of the coupling block 22 of the pedal base 2 in the opposite direction by two holding screws 8. Each of these movable holding plates 7 carries two perforated tabs 71 which overlap a sliding guard 221 of the coupling block 22 of the pedal base 2. The holding bolts 8 each pass through the perforated tabs 71 of the movable holding plates 7 and the twisted, opposite ends of the springs 4 and are then screwed into the transverse end wall 223 of the coupling block 22 of the pedal base 2. Each of the springs 4 carries a central holding area 41, which hangs on a movable holding plate 7 in order to press this in the direction of the coupling flange 52 of the corresponding fixed holding plate 5. In the assembled state, the springs 4 each rest against the stop plates 3. By turning the countersunk screws 6, the stop plates 3 can be moved inwards or outwards, which allows the spring force of each spring 4 to be relatively adjusted.

In summary, the bicycle pedals comprise a pedal base, two fixed holding plates attached to the pedal base in opposite directions, two movable holding plates

ten that pivot about respective retaining bolts on the pedal base to press against the fixed retaining plate to engage the sole of a cycling shoe. Two stop plates slide in two sliding slots on the pedal base, and two springs grip the retaining bolts and abut the stop plates, over-engaging the movable retaining plates to press the movable retaining plates against the fixed retaining plates. Two countersunk head screws are respectively screwed into corresponding countersunk threaded holes on the pedal base and corresponding threaded holes on the stop plates and are rotated to adjust the stop plates relative to the springs to adjust the spring force of the springs.

It should be expressly stated again at this point that the foregoing description is merely an exemplary one and that various changes and modifications are possible without departing from the scope of the invention.
