Definitions

  • the cleat is fastened in a sole recess of the profile directly to the outsole of the shoe. In this space only interact with the cleat interacting with holding devices. In this engages a typically hook or clamp-shaped holding ⁇ device, which is held by a spring in position.
  • the holding device projects relatively far beyond the rest of the pedal body upwards.
  • the spring yields and presses the holder from its rest position. It should be noted that the holding device can be pushed out of its rest position with this system, which may be undesirable.
  • the holding device can engage one or more projections of the cleat wherein it is driven by the spring snaps back to its rest position, "click” is heard by a charac ⁇ ULTRASONIC Therefore.
  • Such pedals are often called “clipless pedals”.
  • To release the shoe must be rotated. In this case, further projections of the cleat press the holding device against the spring force until the cleat and shoe are released.
  • a reduction in the height of a pedal allows a positive change in the geometry of the wheel by the saddle can be lowered by the value that has been saved on the height of the pedal over a conventional pedal. In this way, as a result, a lower center of gravity and a lower air resistance is achieved. Efforts to minimize building heights have so far only led to improvements in a rather marginal area. In addition, since well-known and proven techniques have been retained, the reductions in bearing dimensions and axle dimensions have resulted in a deterioration in function and durability.
  • a first major problem is the provision of a sturdy pedal system with good comfort and durable storage.
  • the holding devices In order to reduce the height, it has been proposed to displace the mechanism of the holding device from the pedal body into the cleat, e.g. in the case of the pedal of the company Bebop® and the pedal of the company Speedplay® (DE 695 22 925 T2) shown in the publication EP 0 515 542 B1.

  • the object of the present invention is therefore to provide a safety click pedal system, hereafter referred to as "system”, which avoids the disadvantages known from the prior art.
  • the system should have a low height and have a low weight, and the number of parts needed should be as low as possible, resulting in lower costs.
  • the storage should have a high durability, without this being at the expense of height and / or weight.
  • the system should be insensitive to soiling, both in mountain biking as well as in everyday life to allow safe operation.
  • the basis of the invention is the recognition that it is necessary to re-arrange any parts limiting the height in a suitable manner, without increasing the risk of pollution-related problems.
  • This refers specifically to the parts of the holding device and that part of the bearing which transmits the main part of the force.
  • a material must be used, which offers the highest possible strength at low volume.
  • the “sagittal plane” S is the plane that is perpendicular to the rotational axis D of the pedal body 1 and extends approximately through the center of the pedal body 1, the “transverse plane” T is the plane to which a viewer in a top / bottom plan view looks; the not shown "frontal plane” is perpendicular to the aforementioned levels.

This may be useful, since a relatively far outward rotation of the mounted on the cleat 3 shoe may be desired, while an inward ⁇ rotation should be limited due to the risk of collision with the pedal crank tight.

L'invention a trait au domaine des pédales pour véhicules mus par la force musculaire. L'invention concerne en particulier le domaine des pédales automatiques de sécurité. Le système de pédale automatique de sécurité pour vélos comprend un corps de pédale (1) pourvu d'au moins une partie arceau à déclenchement (9), un axe de pédale (2) solidarisé au corps de pédale (1) et une cale (3), la partie arceau à déclenchement (9) comportant au moins un élément de retenue (10) mobile réalisé sous forme de ressort à lame et pourvu d'au moins une zone de retenue (11), ledit au moins un élément de retenue (10) étant en outre agencé dans le corps de pédale (1) et ladite au moins une partie arceau à déclenchement (9) présentant une zone de pédalage (13) reliée au corps de pédale (1) à force et/ou par liaison de matière, laquelle zone de pédalage protège ledit au moins un élément de retenue (10). Le ressort à lame comporte une extrémité (18) présentant une géométrie appropriée pour recevoir un élément de fixation et pour coopérer avec celui-ci, et l'élément de retenue (10) est bloqué par la zone de pédalage (13), empêchant tout relèvement de celui-ci.
