Definitions
- the invention relates to a pedal for a bicycle with a sleeve rotatably mounted on a pedal axle, which has a pedal forming a forefoot support and a metatarsal support attached to the pedal and inclined with respect to the forefoot support.
- the leg strength must be transferred richly to the pedal, which entails a corresponding foot load.
- the forefoot is angled relative to the midfoot, so that the force is transmitted to the pedal via the angled forefoot.
- the muscles that hold the forefoot in the angled position are therefore stressed accordingly, which leads to early fatigue for inexperienced cyclists.
- the invention has for its object to provide a pedal for a bicycle of the type described in such a way that an advantageous support of the angled forefoot is achieved with a simple, weight-saving construction and favorable structural conditions are created to make an additional adjustment of the foot posture with respect to To allow longitudinal axis of the foot.
- the invention solves this problem in that the pedal consists of a pedal bracket with two legs, of which the rear leg is extended in relation to the foot support to the metatarsal support.
- the midfoot bracket can consist of a support leg which is pivotally adjustable on an angled leg end of the pedal bracket and which thus determines the angular position of the metatarsus relative to the forefoot determined by the forefoot support.
- the radial distance of the swivel bearing of the rear leg of the forefoot support from the pedal axis can be smaller than that of the front Leg can be chosen.
- the pivoting of the pedal bracket about an axis running in the longitudinal direction of the foot should preferably take place against the force of a spring determining a central position for the pedal bracket.
- a constructive possibility of such a resilient support arises if, in particular, the rear leg of the forefoot support is at a distance from the bearing axis has a receiving opening for an elastic support ring arranged on a radial support shoulder of the sleeve.
- Another possibility is to support the pedal bracket on a bending rod that is clamped on the sleeve and runs in the direction of the pedal axis. If such a bending rod is not sufficient for the swivel limitation, the swiveling movement of the pedal bracket about the bearing axis running transversely to the pedal axis can also be limited by stops.
- Fig. 1 shows an inventive pedal for a bicycle in a side view
- Fig. 2 shows this pedal in a plan view
- Fig. 3 is a representation corresponding to FIG. 2 of a construction variant of a pedal according to the invention.
- the pedal according to the illustrated exemplary embodiments has a pedal axle 1 with a threaded attachment 2 for attachment to a pedal crank of a bicycle and a pedal bracket 3 for foot support.
- this pedal bracket 3 is not mounted directly on the pedal axis 1, but on a sleeve 4 which can be freely rotated about the pedal axis 1.
- the sleeve 4 is provided with radial projections 5 and 6 which have a bearing axis 7 extending transversely to the pedal axis 1 result in the pedal bracket 3.
- the pedal bracket 3 not only forms a forefoot support 8, but also a metatarsal support 9, which has an inclination angle with respect to the forefoot support 8, as can be seen in FIG. 1.
- the forefoot support 8 is formed by a front leg 10 with respect to the foot support and a rear leg 11 of the pedal bracket 3. These legs 10 and 11 are with the aid of screws 12 on the radial lugs 5 and 6 the sleeve 4 pivotally attached.
- the rear leg 11 of the forefoot support 8 is provided with a receiving opening 13 for a rubber-elastic ring 14 which is attached to a radial support shoulder 15 of the sleeve 4, so that the pedal bracket 3 against the restoring force of the elastic ring 14 rubber-elastic ring 14 can be pivoted about the bearing axis 7 in a limited manner.
- a spring rod 16 is provided for resilient support of the pedal bracket 3, which is rigidly attached to the end face of the sleeve 4 and engages in a bore 17 of the pedal bracket 3. Since the spring rod 16 extends transversely to the bearing axis 7, the pedal bracket 3 can only be pivoted about the bearing axis 7 by bending the bending rod 16. So that the pivoting movement of the pedal bracket 3 can be limited independently of the bending stiffness of the spring bar 16, the radial support projection 15 of the sleeve 4 serves as a pivot stop. For this purpose, the support projection 15 engages with a radial clearance in a recess 18 of the rear leg 11 of the pedal bracket 3.
- the metatarsal support 9 is adjustable with respect to the forefoot support 8 with respect to the angle of inclination.
- this adjustability of the angle of inclination is achieved in that a support leg 20 of the metatarsal support 9 is articulated on the end 19 of the rear leg 11 of the forefoot support 8 which is angled backwards.
- This articulation takes place via a preferably riveted axis 21, to which an elongated hole 22 is provided concentrically in the support leg 20 and through which a clamping screw 23 held in the leg end 19 passes.
- this clamping screw 23 By means of this clamping screw 23, the respectively set inclination of the support leg 20 with respect to the forefoot support 8 can be determined.
- the radial extension 6 of the sleeve 4 is shorter than the opposite extension 5, so that an eccentric position with respect to the pedal axis 1 results for the forefoot support 8.
- the resulting shift of the pedal bracket 3 to the front takes into account the different force ratios that result from the foot support in both the forefoot and midfoot area.
