Definitions

  • the invention relates to a bicycle pedal with a safety lock for locking a shoe to a bicycle pedal according to the preamble of claim 1.
  • a generic bicycle pedal with a corresponding safety lock has become known from FR-Al-2 648 104.
  • the associated coupling device has leading and trailing angular lugs which pass over legs which run more perpendicularly to the pedal plane into engagement sections which are aligned parallel to the pedal plane and point towards one another.
  • a coupling counter-device is provided on the underside of the shoe, which has engagement projections pointing forwards and backwards in the direction of the shoes. Since the angular, pedal-side engagement sections are designed to be resilient and the engagement projections formed on the underside of the shoe are provided with an inclined ramp on their underside, it is possible, by the occurrence of the Shoe on the pedal to ensure that the engaging projections engage behind the angular resilient engaging portions te locking. It is a kind of snap connection.
  • the engagement projections formed on the underside of the shoe have locking elements which run essentially parallel to the longitudinal direction of the pedal, that is to say parallel to the pedal axis, and which are comparatively wide.
  • a largely similar bicycle pedal for securing a shoe to a pedal has also become known from FR-Al-2 612 869.
  • resilient support legs protruding perpendicularly to the pedal plane and spaced apart in the longitudinal direction of the pedal are fastened and held on a pedal body, specifically by means of a quadra cross section which is separately fastened to the pedal body ⁇ table intermediate carrier.

  • On the underside of the shoe protruding engagement projections are again formed in the opposite direction to the front and back. Since these engagement projections are again provided with a flattened ramp on their underside in a leading and trailing manner, it can be ensured by fitting the shoe that the engagement projections snap behind the engagement sections held above them by widening the resilient support legs can.

  • These flange sections are material and / or shape urgent at least slightly resilient, so that the connection can be made or released according to a rotation and / or lowering or lifting movement by latching or unlocking.
  • the spring force is to be changed, then only a different plate-shaped coupling element has to be used, the opposite flange-shaped leg of which has slightly different elastic spring characteristics due to a different choice of material, different material thickness and / or different material shape.
  • the engagement sections are provided with engagement recesses into which the engagement projections provided on the underside of the shoe can be anchored in an engaging manner.
  • This connection between engagement projections and engagement recesses also ensures that a shoe secured to the bicycle pedal is optimally centered. This is because the solution according to the invention ensures that the shoe is fixed even when the force is applied in the direction of the pedal axis. Nevertheless, by turning the shoe, the locking position can be released at any time and the shoe can be released from the pedal.
  • two mounting plates are used instead of a single mounting plate. These are preferably attached to the leading and trailing area of the pedal in such a way that they have flange or engagement sections which project substantially in the vertical direction and which are provided with the engagement area already explained above.
  • the two essentially vertically extending mounting plates can be designed to protrude both upwards and downwards, so that the upper and lower sides of the pedal body are virtually identical and, depending on the position of the pedal, the locking on both sides can be made with a bottom of the shoe.

Abstract

Une pédale de bicyclette pourvue d'un verrouillage de sécurité permettant de bloquer une chaussure sur ladite pédale, comporte un dispositif d'accouplement situé côté pédale et un contre-dispositif d'accouplement situé côté semelle de la chaussure (11, 25). Le dispositif d'accouplement situé côté pédale (11) comprend, dans le sens de la marche de la pédale (1) de la bicyclette, des sections de contact (15', 15') espacées et des sections de montage (13, 113) qui soutiennent ces sections de contact (15', 15'). Les sections de contact (15', 15') comprennent des plaques sensiblement perpendiculaires au plan de la pédale et ces sections de contact (15', 15') en forme de plaques comprennent chacune une cavité de contact (17', 17'). Lorsque le système est verrouillé, les parties saillantes de contact (29, 31), qui débordent côté chaussure une fois vers l'avant et une fois vers l'arrière, s'engagent dans les cavités correspondantes (17' et 17') situées côté pédale.
