FR2645721A1 - SHOE WITH PLATE FIXED TO THE SOLE FOR BICYCLE SAFETY PEDAL - Google Patents

Abstract

A shoe with a plate attached to the sole for coupling with a safety bicycle pedal is described, which is provided with at least one support element in the area between the plate and the end of the shoe, improving comfort of walking, resp. stroke and at the same time having a plate protection.

Description

-1- 2645721

  The invention relates to a shoe with a plate fixed to the sole, arranged in the eminence area of the big toe, for releasable attachment to a bicycle pedal provided with a coupling and release device. Shoes of this kind are known and are used in

practice in large numbers.

  Because the plate exceeds the sole and, conditioned by its function, extends only over the area of the eminence of the big toe, such shoes do not have a full-surface pose for walking, so that , on the one hand, - they present a certain inconvenience for walking and, on the other hand, - there is above all the danger that the plate can be damaged by colliding with objects which would have a negative influence on its function coupling. The object of the invention is: to improve a shoe of the kind indicated above in a simple and economical manner so that the comfort of walking and at the same time the protection of the plate against damage

will be improved.

  This problem is' solved - mainly - in that between the plate and the toe of the shoe, at least one support element - is provided, whose diverted surface of the sole is at least mainly in the imaginary extension of the surface of the plate serving as a support plane. By this support element which represents an auxiliary for walking, a support surface of a large surface area and avoiding tilting is created, which allows normal operation of the shoe during walking and running, and that 'in addition this support element protects. first of all the coupling shoulder before the plate against damage, then an involuntary shock on this coupling shoulder will be avoided thanks to the function

  corresponding protective device exerted by the support element.

  In addition, this support element has a very favorable aerodynamic characteristic when the shoe is attached to the pedal, because it directs the air flow arriving around the place of front coupling between the pedal and the plate. effectively avoiding air turbulence. Finally, one could cite the advantage that this support element avoids unwanted fouling of the front coupling zone of the plate, when it is necessary to move under road conditions

unfavorable.

  Particularly favorable achievements of

  the invention are indicated in the claims

  secondary. An example of an embodiment of the invention is shown in the drawing; in this drawing: Figure 1 shows a schematic side view of a

  shoe executed according to the invention, -

  Figure 2 is a plan view of the sole of the shoe

of figure 1.

  Figure 1 shows -n. shoe of: sport.de -cyclisme with a plate 2 attached to the sole, dispersed in the eminence zone of the big toe and which has - at its front end a front coupling shoulder 6 and a recess 7. its rear end .'Plate 2 with its corresponding coupling members of a so-called safety pedal is detachably attached to this

  coupling shoulder. 6 and the recess 7.

  A support element 3 is provided in the area. between the toe of the shoe and the plate 2 which is attached

firmly to the sole 4.-

  This connection can be achieved by an execution. In one piece with the sole, but it is also possible to attach to the sole 4 a support element separated from. in a sustainable way and using fixing means

  appropri s, for example-by screwing. or gluing.

  According to another alternative embodiment, the plate 2 can be extended, so as to have a flat arch, towards the toe of the shoe and provided directly with '11 support element, so that the plate 2 and the support element 3 can be

mounted as a set.

  The surface 5 of the support element, serving as a laying plane. is located in the imaginary extension of the upper surface of the plate, serving as a laying surface and may still have a bevel towards the point of the

  lift, increasing the comfort of walking.

  The plan view of the sole 4 according to FIG. 2 'shows the basic shape of the plate 2, which can be provided with an elastic insert 8, and which has a rounded coupling shoulder. 6: from the side of the shoe tip, used to further improve walking comfort and protection of the plate._ This' support element 3 is fixed to the sole 4 opposite the coupling shoulder 6. -In its outer zone the support element 3 adapts mainly to the contour of the sole, and the zone opposite the coupling shoulder 6 is executed in a curved manner, the radius of curvature being greater than the radius of curvature of the shoulder

coupling 6.-.

  The effective free zone between the coupling shoulder 6 and the support element 3 allows easy engagement of a stirrup. of the body of. matching pedal clinging

  behind the attachment shoulder 6.

  Since the support element 3 does not have a coupling function, but only a support function, it can be made of a material which is different from that of the plate. A softer material is more comfortable for walking, compared to that used for the turntable, is preferably used, so that more particularly, the sliding effects during

  walking and running are avoided.

  In the case of an integrated execution of the support element 3 and of the plate 2 the upper surface of the support element is executed so as to make it rough, and, preferably, the element support is fixed to the extension of the plate, and in the latter case a softer material than that of the plate can be used for the support element.
