FR2888205A1 - Cleat support sole for e.g. cyclist shoe, has metal plate at which anti-skidding plate is twined, and two quick adjusting locking straps fixed on metal plate by rings, where sole is pierced of five rails for fixing cleat - Google Patents

Abstract

The sole has a metal plate (1) at which an anti-skidding plate (2) is twined. Two quick adjusting locking straps (6) are fixed on the metal plate by rings (5). Front and back of plate are pierced of two holes (9) sufficiently spaced from one another in which screws (10) of different sizes are inserted and fixed by nuts (11). The sole is pierced of five rails (7) for fixing a cleat (8).

Description

The present invention relates to a device for wedging the foot on a

bike pedal.

  Traditionally, the cyclist is obliged to buy "special" shoes if he wants to use the pedals (female) for cleat (male). These shoes are narrow, and the "rails" where the cleat (the wedge) is positioned are located 1 'front of the sole of the foot. This reduces the effectiveness of the muscular work provided.

  In addition, very often, the soles of these shoes are very hard plastic; they tend to slip (to skid) on the pedal when the cleat is not engaged. And finally, they are expensive, these shoes "special".

  They must be replaced every time the pedals are changed, each time the foot grows, and of course every time they are worn.

  The cleat-bearing sole comprises a metal plate (1). Is bonded under this plate (1) a plate (2) rubber (or polymer). Of course, wherever the plate (1) is pierced or crossed (by a screw for example), the plate (2) is also.

  At the four corners of this plate (1) are located four screws "holes" (3) which is fixed by means of nuts (4). - 2

  In the hole of these screws (3), a ring (5) is passed. The four rings (5) will be used to "attach" the two quick-release clamps (6). In the middle of this plate (1) are drilled five rails (7) which will be used to fix the cleat (8). These rails will be located on the left for the right foot, and on the right for the left foot.

  At the front and rear of the plate (1) are drilled two holes (9) sufficiently spaced from each other (and edges of the plate (1) too), in which we will insert screws (10) of different sizes. These screws (10) will be fixed with nuts (11). Everything will be securely attached to the foot shod (12). The quick couplers will be on the opposite side to the rails (7).

  The plate (1) (iron or stainless steel, for example) may have a length of about twelve centimeters, and a width of about ten centimeters.

  These sizes will fit most adult shoes. It will be necessary to envisage a size "teenager" and a size "child" It will have a thickness of at least two millimeters. It will not bend, and will be relatively light.

  The size and rigidity of this plate (1) will improve the foot sitting on the pedal, the leg muscles will work "better", and the rider will gain power (and balance too). The plate (2) will have a thickness of about one millimeter. It will have an anti-slip role.

  We can rotate the nuts (3) on themselves before tightening, we can adjust the orientation of the rings (5) and adjust the positioning of the straps (6) to the type of shoe used or the morphology of the foot .

  The rails (7) will be five in number and will have a length of about seven centimeters. Thus, the cyclist will have much more choice to find the position of the wedge (8) ideal; the proper position to his own way of pedaling.

  The first two rails will be located in the middle of the plate (1). The other three on the right, or on the left. Of course, they will be spaced so that they can all, coupled, welcome the cleat (8) (first and second rails, second and third, third and fourth, fourth and fifth). The screws (10), inserted into all (9), will be used to reduce the "sliding" between the plate (1) and the sole of the shoe. Thus, the forces exerted on the straps (6) will be less. We can choose, for example, three sizes of screws (10) (four times a centimeter, four times a centimeter five, or four times two centimeters). Or twice two centimeters in the front, and two times a centimeter in the back. - 4

  In fact, the length of the anti-slip screws (10) will be adapted to the type of shoe (sole) used; spiked sole, smooth sole, heels.

  The diameter of these screws will be about five millimeters.

  The number and the length of the rails (7), as well as these screws (10), will even allow this cleat-carrying sole to accommodate some orthopedic shoes.

  Finally, the quick-attaching straps (6) will press the cleat-bearing sole against the sole of the shoe. - 5 -

  The plates (1) and (2) can be cut and machined at the mayen of numerically controlled machines.

  Screws, nuts, straps and rings can easily be found at various suppliers.

  (The locking tabs (8) are sold with the pedals.)

Claims (3)

- 6 - CLAIMS   1) Device for using the locking cleats with any type of shoe, characterized in that it comprises a metal plate (1). -to which is coupled a non-slip plate (2) - to which are attached two clamping straps with quick coupler (6) - in which are inserted anti-slip screws (10) - in which are drilled five rails ( 7) with which is fixed a cleat (8). 2) Device according to claim 1 characterized in that the cleat-bearing sole adapts to any type of shoes.   3) Device according to claim 1 characterized in that.   the cleat-bearing sole improves the foot support on the pedal. The cleat-bearing sole increases the number of possibilities for positioning the foot on the pedal.   the cleat-holder sole necessarily slips less easily than a cleat-door shoe.   the cleat carrier is cheaper than the pote-cleat shoe.   the cleat-bearing sole is stronger than the cleat shoe.   the cleat carrier sole is simpler and less expensive to manufacture than the cleat shoe. 15
