ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a foot cleat, more particularly to a foot cleat for securing a cyclist's shoe, to a bicycle pedal suitable for both racing bicycles and mountaineering bicycles.
2. Description of the Related Art
FIG. 1
shows a toe cleat
10
made of metal material for attaching fixedly the sole of a cyclist's shoe to a pedal body (not shown). The toe cleat
10
has front and rear engaging portions
12
,
13
for engagement with the pedal body, and an intermediate portion
11
having an elongate transverse slot
14
for receiving an elongate washer
15
and two lock holes into which two screws
16
may be inserted so as to fix the toe cleat
10
on the bottom surface
17
of the sole of the shoe.
Referring to
FIG. 2
, another form of a conventional toe cleat on the pedals for a racing bicycle is shown. The toe cleat
20
is made of plastic material, and also has front and rear engaging portions
22
,
23
for engagement with the pedal body (not shown), and three slots
24
arranged triangularly therein which, along with the washers
25
and screws
26
, fix the toe cleat
20
to the shoe sole
27
.
Since the above toe cleats
10
,
20
of the pedals have different shapes and sizes, and since the screw holes in the soles of the cyclist's shoes are located in different positions, the toe cleats
10
,
20
are not suitable for fastening to all types of shoes.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a foot cleat adapted to secure a cyclist's shoe to a bicycle pedal, suitable for both racing bicycles and mountaineering bicycles.
According to this invention, a foot cleat includes a foot cleat body with a second engaging major surface adapted for facing toward a first engaging surface of a petal body. The foot cleat body is formed with an elongate lock slot extending in a transverse direction, and two lock holes provided in two opposite sides relative to the elongate lock slot and aligned in a longitudinal direction. Two friction members are disposed in two lateral portions of the foot cleat body and extend outwardly of and extend outwardly of the second major engaging surface to abut against right and left tread walls of the pedal body so as to prevent slippage of the foot cleat body relative to the pedal body. Screw fasteners are inserted through the elongate lock slot and/or the lock holes in such a manner that the screw fasteners are adjustably positioned at the elongate lock slot which is adapted for registering with the screw holes in the bottom surface of the sole of a cyclist's shoe so as to be engaged selectively and threadedly in the corresponding ones of the screw holes.
