    Bicycle pedal that allows an ergonomic anchoring of the foot. The product described in the patent is a pedal indicated for conventional bicycles, since they allow a fixation of the correct pedaling position (recommended by ergonomic studies) with an elastic condition in order to facilitate the rapid response of the cyclist at times when it is needed of it. The geometry of the elements present in the body forces the foot to step properly always, adapting the conditions of the individual shapes to the size of the foot width and fixing the position with a system that, through the tightening applied by the user, prevents losing the chosen physical reference. All this mechanism moves in solidarity with the ends and being isolated from the outside to ensure proper operation during its half life.

    DESCRIPTION
    Bicycle pedal that allows ergonomic anchorage of the foot.
    Technology Sector
    The present invention relates to a pedal adaptable to the width of the human foot according to its variations in size stipulated by the UNE 59850 standard and the average, minimum and maximum sizes included in the UNE-EN ISO 7250-3 standard.
    It seeks to position the user pedal at all times correctly without restricting the necessary speed of response in harsh environments for the cyclist.
    State of the art
    Numerous inventions are known that aim, in one way or another, to position the cyclist's feet with systems that force the posture to be conditioned. However, in some of them there is a circumstance that, either, the raised tread area does not respond effectively to the ergonomic criteria that this invention requires; or they restrict too much the movements by anchors and fixings not very flexible with the geometric differences existing between different footwear.
    The first reference in the investigation is located in the patent ES 0125106, in which there is an invention in which there are two metal side pieces that prevent lateral sliding. The biggest difference is that these are straight, do not contemplate the curvatures existing in the soles of the shoes and do not exert any friction on the lateral surface in contact.
    An invention more similar to the model set forth in this document is patent number US 626125, since it seeks the support of the feet through a side pieces. However, the tightening is done in an incorrect area of tread and the variation of the system comes from both sides, without keeping one of them in a constant position. Therefore, the adjustment turns out to be more inaccurate and there is more ease of gaps during pedaling.
    The same relationship is found in example US 565788 although the difference with the previous model is found in the assembly of an arc similar to the current strips. Taking into account that in the new invention these supports have been suppressed in order to avoid attaching the limb to the pedal, the fall response of this prototype is much worse because it can cause damage to the user.
    There are inventions that seek total support of the foot regardless of the shoe to be used, naming as cases the utility models CN 2582672Y and ES 2540376. However, the position apart from being restricted by a tape in the area of the forefoot, this does not respond with a form adapted to the ergonomic criteria of a correct pedaling position.
    Regarding the application of a fixed side that forms part of the pedal structure there are similarities in US Patents 20080156142 and US 20110283829, whose main difference between them is in the assembly of these additive structures. In the case of this new invention, the supports close to the axis have a tubular structure and a slight frontal support. This geometry is dispensed with in the new design so as not to prevent a rapid separation of the foot with the pedal, the main objective in the development of the model.
    The correct pedaling position is also determined in the invention US 20090320641, although with two different ways of guaranteeing it: in this patent is the sole of a shoe

    special that manages to attach to a pedal body, being its fixation secured by the friction of the material. However, this proposal does not require specialized footwear, since it is the pedal itself with its geometry and the friction caused in the soles that forces the position. A similar case is found in document ES 2091485 since it also requires the use of special footwear, although in this case the anchoring is greater since the sliding backwards of the foot is prevented with the pedal structure.
    Brief Description of the Invention
    The product described is a pedal indicated for conventional bicycles, since they allow the correct pedaling position to be fixed (recommended by ergonomic studies) with an elastic condition in order to facilitate the rapid response of the cyclist in environments that require it. The geometry of the fins present in the body forces the foot to always step properly, and through its mobile end adapt this step to the size of the foot width. It also has a threaded bolt at the end, sliding inside the body and which allows to fix the position once the system is adapted to the width of the user's foot.

    Detailed description of the invention
    This invention aims to achieve a correct pedaling position by the user without the requirement of fixations that attach the foot to the pedal or that need special types of footwear. It seeks to condition the posture in order to achieve the indicated in various studies of the movement of the lower frame. For this, the pedal geometry adapts to the size and shape of conventional footwear. Its working range is independent of the length of the foot, since the whole adjustment is across its width. Variations of this dimension are limited to a specific longitudinal range in which all sizes of conventional shoes move.
    The main support of the pedal is provided by the body (1) and the mobile end (2), of ribbed geometries and manufactured with a material that combines high mechanical resistance with low specific weight. Each one has two lateral flanges (one for each side) with a wide radius that allows adaptability to the curvature of the soles, both on the ground and in its elevation, helping to position the cyclist's foot correctly. In order to improve the response even more, the lateral friction of the tires (10) and on the platform with the different grooves positioned in the critical pressure zones is available. The union of the rubbers is done with an adjustment in which part of these elements adapts to the existing through spaces on the sides. An adhesive is also applied between the surfaces in order to avoid its

    detachment The final objective of all these elements is to permanently fix the position, since what is sought is to avoid at all costs a restriction that prevents separation in the event of an accident, which inevitably forces a more open restriction.
    The working path of this pedal must be adapted to the foot sizes, but it is necessary to prevent the end from showing too much to the outside and causing accidental collisions with the footwear during use. This is why the sides of the body are emptied so that the adjustable end can be moved inwards, which allows the body and end dimensions to be reduced in length. The fixing system exerts its functions on these recesses, in particular on internal rails through which a head slides (6).
    In one of the lateral stops of the mobile end there is a threading through which the fixing bolt (7) is mounted. Its assembly is composed of the head mentioned above, a spring (15) housed inside the bolt and that its function is to ensure that the head always has contact with the body and, finally, the bolt that is threaded to the end of the pedal. To ensure the tightness of the rails and not to damage the fixing task, two small stops (12) are attached to the notches of the rail exit, fulfilling a closing function.
    This entire system exerts a tightening on these internal faces, in such a way that the end is prevented from moving from the position that the user desires unless the end suffers accidental efforts (difficult to apply during normal use) the system would slide in order to avoid reaching the deformation of the piece. The adjustment is made in such a way that when the user installs the system, he must find that the footwear must not be tight so that its separation is not possible by applying a little effort, since once the ideal position is achieved, the assembly does not It must move.
    The insulation of the fixation is done with some lateral covers (3), manufactured with a reflective component that helps the visibility of the piece. Its assembly has three points of union with the pedal body: Geometric union through a lateral projection, detachable union with a screw (13) and through a bushing (5) housed at one end of the cover and screwed to the body (14).
    This assembly is also raised in such a way that it serves as a limit of the movements of the end, since when it collides with its front faces the end reaches its minimum position, and when it bumps into the internal contact of the side cover it reaches its maximum position . In the cover that does not contain the fixing bolt a support (4) is mounted designed to house a commercial reflector (21) inside. Its union with the side cover is made with an adhesive, since what is intended is that the union between these two pieces is final.
