Definitions
- the present invention relates to a device for connecting a shoe to a sporting article element such as cycle pedal, bicycle or similar device. It also relates to the parts of this device integral with the pedal as the shoe.
- the oldest system consists of a kind of cage associated with a belt, commonly called foot-block, which traps the front half of the shoe, once the belt tight and makes said shoe completely integral with the pedal.
- a device has the disadvantage of ensuring a permanent locking of the shoe on the pedal and not to allow a quick release thereof in case of need and in particular when there are risks of accident or fall, or during a stop when the cyclist must land on the ground.
- This type of automatic pedal nevertheless requires a certain amount of time for the user to learn the movement of rotation of the foot towards the outside if necessary, not being a natural movement.
- Such a construction has the disadvantage that the recess of the sole is very important and can be a housing for mud, pebbles, when walking.
- this recess is completely hidden because it is set back from the outer envelope of the walking surface and delimited by two kinds of step, especially at the front, which impede the placement of the soleplate on the pedal. In other words, the user must fumble before finding the exact match between the pedal and the recess of its sole.
- connection is made using elements of the sole, the crampons, which are subject to wear during walking and can make the connection unstable due to premature wear. Clearance when needed is also not easy.
- connection devices are the footrest or automatic cleat / pedal systems mentioned above.
- the foot should be positioned so that the axis of the metatarsophalangeal joint is approximately aligned with the axis of rotation of the pedal.
- connection / wedging / fixing devices described above.
- the user In the absence of such connecting devices / wedging, the user often misplaced his foot, for example too far back on the pedal, or the foot arranged in a fan with respect to the axis of the pedal.
- the object of the present invention is to provide a device for connecting a shoe to an element of a sports article such as a pedal that overcomes the disadvantages mentioned above.
- One goal is to facilitate the connection shoe / pedal even blind. Another goal is to ensure correct positioning of the foot relative to the pedal.
- Another goal is to have a connecting device that poses no risk of locking the sole when needed.
- the attachment members of the soleplate do not protrude beyond the external envelope surface of said soleplate and are therefore not subject to risks of inadvertent wear. They do not interfere with walking.
- the external envelope surface of the sole is raised upwards in front of the zone of the attachment members of the sole.
- This construction defines a ramp at the front of the attachment members and thus facilitates the engagement of the shoe on the pedal, even blind.
- FIG. 1 is an exploded perspective view of the sole of the shoe and the pedal before mutual connection
- FIG. 2 is a side view of the shoe / pedal assembly during engagement of the shoe on the pedal;
- FIG. 3 is a view similar to FIG. 2, the shoe being linked to the pedal;
- FIG. 4 is a perspective view of the pedal
- FIG. 5 is an end view of the pedal of FIG. 4,
- FIG. 6 is a view from above of the pedal of FIG. 4,
- FIG. 7 is a side view of the pedal of FIG. 4;
- FIG. 8 is a bottom view of the shoe sole;
- FIG. 9 is a sectional view along DC-DC of FIG. 8,
- FIG. 10 is a view similar to FIG. 8 according to another embodiment.
- FIG. 11 is a sectional view along XI-XI of Figure 10.
- Figures 1 to 3 illustrate the binding device of a shoe 1 to a bicycle pedal 10 during the various assembly steps.
- the shoe is constituted in a manner known per se of a rod 2, surmounting a sole 3 said step.
- the sole 3 comprises a series of step profiles 4, constituted in this case by reliefs 4 shaped waves or wavelets extending generally perpendicular to the longitudinal axis L of the shoe.
- wave-shaped reliefs 4 which are intended to facilitate the attachment of the sole 3 on different terrains, may have different shapes depending on the terrain on which the shoe is intended more particularly to be used.
- each of the waves or reliefs 4 is contained in an envelope surface S whose profile changes in the longitudinal direction of the shoe.
- the sole 3 of the shoe comprises a succession of hollow respectively 5, 6, 7, 8 and a shoulder 9 constituting the attachment members of the soleplate intended to cooperate with the bicycle pedal 10 as will be seen later.
- the bicycle pedal 10 comprises a hinge pin 11 on which is mounted a pedal body 12 having a cross shape 15 with branches 15a, and projections respectively 16, 17, intended to cooperate respectively with the recesses 5, 6 and 7 of the sole of the shoe.
- the branches 15a of the cross are connected two by two by two bars 18 carrying the projections 16, 17.
- the recesses 5, 6, 7, 8 are provided inside or recessed. relative to the external envelope surface S of the soleplate and therefore do not exceed with respect to said outsole 3.
- the shoulder 9 is defined by a cutout of the tread sole 3 and therefore does not exceed either with respect to the external envelope surface S thereof.
- the hollow 5 has a cross or X centered substantially on the axis of metatarsophalangeal articulation M, and complementary to the shape of the cross-shaped block 15 of the pedal.
- the recess 5 is also substantially centered in the transverse direction relative to the sole.
- each branch 5a of the cross-shaped recess ends with an inclined portion 5b.
- each branch 15a of the associated cross shape 15 of the pedal also ends with an inclined portion 15b.
- the dimensions of the crosses 5, 15 are complementary so as to allow mutual interlocking of these shapes with a slight clearance.
- the inclined portions 5b, 15b are intended to facilitate the mutual engagement of the sole and the pedal, particularly in the presence of earth, mud, pebbles.
- the projections and recesses respectively 16, 6 have a polygonal shape substantially chevron-shaped. Each branch 16a of the chevron 16 is inclined relative to the other in the manner of a roof.
- the recesses and projections respectively 7, 17 have substantially the shape of a double triangle. Each face 17a of the triangle 17 is inclined relative to the other in the manner of a roof.
- the dimensions of the recesses / projections 6, 7 and 16, 17 are provided so as to allow interlocking with a slight clearance.
- the bars 18 carrying the projections 16, 17 have in the example shown substantially in the form of a circular arc.
- the shoulder 9 of the sole has substantially the same shape of a circular arc so as to cooperate and serve as a rear stop with one or other of the bars 18 depending on the position of the pedal.
- the pedal body has a double symmetry with respect to its axis of rotation 11. Accordingly the pedal 10 has two symmetrical faces 10a, each having a double series of projections respectively 16, 17.
- Figure 5 also shows that the surface of each of the faces 1 Oa of the pedal has a slightly curvilinear profile intended to cooperate with the curvature 3a of the sole in the longitudinal direction (see Figure 3).
- the upper surface of the cross 15 is therefore slightly below the surfaces of the reliefs 16, 17.
- the recess or recess 8 of the sole 3 has a semi-cylindrical shape and extends from the medial side 3b of the sole on a part of said sole, substantially parallel to the metatarsophalangeal joint axis M (see Figure 8).
- This hollow 8 is intended to cooperate with the axis of articulation 11 of the pedal.
- This construction brings the pedal 10 closer to the foot of the user and is therefore interesting in terms of performance.
- the shoulder 9 ends on each side by a stop 9a, to facilitate the centering of the shoe.
- envelope surface S of the outer sole 3 is raised upwardly in 3c, with respect to the area comprising the recesses 5, 6, 7 and in front of said zone.
- the operation of the binding device of the shoe to a pedal, including a cycle is very simple. It suffices to engage the front end 3c, raised, of the soleplate on the pedal 10, as shown in FIG. 2, and to slide it forward with respect to the pedal until the shoulder 9 comes into abutment against one of the bars 18 of the pedal.
- the relative games between the hollows and the projections allow a certain adaptation to the morphology of the user.
- the X shape of the central connecting members 5, 15 prevents a relative rotation of the shoe relative to the pedal.
- the pedal 10 is in its form compatible with normal shoes since it produces supports by means of the raised surfaces 16, 17 higher relative to the surfaces of the cross 15.
- the crosses 15 are covered. a smooth coating such as POM DELRIN® or PE (polyethylene) or PTFE (Teflon) of the pedal on the sole, while the peripheral relief portions 16, 17 are of a rougher material, to facilitate the hangs on the sole 3.
- Figures 10 and 11 show an embodiment wherein similar or identical elements will be designated by the same references. The only difference with respect to the embodiments shown above is that the sole 3 consists of several materials depending on the different areas 31, 32, 33, 34 thereof.
- the material is made of a material which is harder than in the zones 31, 34 of the sole located on both sides of these areas.
- the material in the zones 31, 34 is made of rubber having a hardness of 65 shA, namely a low hard rubber, having high adhesion characteristics.
- this material may be replaced by a somewhat harder rubber or other material having good adhesion qualities such as TPU.
- the material of the zones 31, 34 may also be different and be for example a harder rubber.
- the material of the area around the protrusions 6, 7 is, in this example a TPU plate from 70 shA to 80 sliA, that is to say a plate of rather hard material and having a coefficient of friction lower than the rubber of the rest of the sole, to facilitate the sliding of the sole on the pedal in the front part of the clipping members.
- this TPU plate is about 2mm thick and is housed in an associated recess of the sole.
- the material of the zone 33 which is therefore the rear part of the zone of the attachment members of the sole, the material is for example a rubber having a hardness of about 80 to 85 shA.
- This zone 33 is therefore a little harder than that of the zones 31, 34 of the sole, while having similar adhesion characteristics.
- the material of this zone 33 may be overmolded with the remainder of the sole, since in the same type of material as that 31, 34 of the other zones thereof. Depending on the case it may be a plate.
- This greater hardness of the material in the zone 33 makes it possible to limit the wear and the deformations of the parts cooperating with the sole.
- the fact of keeping a rubber-like material in this zone is however interesting to keep a good attachment of the sole on the bike pedal.
