Definitions

  • the invention relates to a bicycle pedal with a crank arm, at the radially outer end of which a pedal body is provided which can rotate freely with respect to the crank arm about a horizontal transverse axis which is perpendicular to the crank arm, the pedal body itself about a horizontal plane running in the direction of travel and the transverse axis intersecting the longitudinal axis is pivotable, and with a first connecting element which is releasably connectable to a complementary second connecting element which is provided on a user's shoe.
  • Such a bicycle pedal is known from DE 32 18 290 A I. It is a pedal training device that has several degrees of freedom of movement compared to its crank arm.
  • the pedal body is attached to a ball, which is mounted in a hollow bowl.
  • a bicycle pedal is also known from FR 2 509 249, in which the pedal body is pivoted about the axis that runs in the horizontal plane in the direction of travel and intersects the transverse axis. In this case, however, no swiveling is provided during use, because the pedals should be fixed once according to the needs of the user of the bicycle before it is put into operation.
  • the driver's feet are inclined via the fixed and rigid connection between shoe and pedal. Since the vertical alignment of the body is also carried out by the legs, it is the driver's ankles that are in an anatomically incorrect position and in which the tilt is transmitted. On the one hand, this leads to a considerable strain on this body area and on the other hand, this human transmission axis reduces the effectiveness of the driver's use of force.
  • the invention has for its object to provide a bicycle pedal of the type mentioned, which allows in a simple and inexpensive manner that it does not lead to anatomical malpositions of the lower extremities, in particular, even when using the rocking pedal in the ankle area, so that the forces used are implemented as completely as possible in the pedal drive.
  • the object is achieved with a bicycle pedal according to the preamble of claim 1 on the one hand in that the longitudinal axis allowing the pivoting of the pedal and extending in the direction of travel of the bicycle is arranged between the pedal body and the first connecting element.
  • the object is achieved with a bicycle pedal according to the preamble of claim 1 on the other hand in that the pivoting of the pedal and in the direction of travel of the bicycle extending longitudinal axis is arranged between the transverse axis and the pedal body.
  • the object is finally achieved with a bicycle pedal according to the preamble of claim 1 in that the pivoting of the pedal and extending in the direction of travel of the bicycle longitudinal axis is arranged between the second connecting element and the shoe of the user.
  • FIG. 1 is a schematic and partially sectioned rear view of a pedal with a shoe attached according to a first embodiment of the invention
  • Fig. 2 is a bottom view of a shoe for use with a
  • FIG. 3 shows a partially sectioned top view of a pedal with shoe latches according to a second exemplary embodiment of the invention
  • Fig. 4 is a cross-sectional view of one half of the central tube of the
  • Fig. 5 is a plan view of a pedal with shoe latches according to a third embodiment of the invention.
  • FIG. 1 shows in partial cross section a schematic representation of a pedal according to a first embodiment of the invention in the direction of travel.
  • Reference number 1 denotes the pedal axis, which is articulated in the usual way on the radially outer end of the crank arm, not shown in the drawings.
  • the pedal or transverse axis 1 runs perpendicular to the crank arm.
  • a bearing (not shown for the sake of simplification of the drawing) for the pedal body 2, which can rotate freely about the transverse axis 1.
  • the pedal body 2 corresponds to the known pedal bodies, i.e. it has two opposite symmetrical pedal surfaces 3, on which the cyclist can put his foot down.
  • the box device 4 consists of lateral rails, each having a lateral guide gap 5, into which a corresponding edge of a shoe element can be inserted in a positive fit.
  • the rails are advantageously L-shaped in plan view and thus have a front stop, so that the shoe is pushed into the rails from behind and is then also fixed in the direction of travel.
  • These rails can be interrupted and can be provided in several aligned rail parts.
  • Fig. 1 the sole of a shoe 6 is also shown schematically. It can be seen that the shoe 6 has a central recess 7, which is preferably located in the area under the front ball of the foot, as can be seen in FIG. 2, in the direction of the foot and thus when the shoe 6 is used in the direction of travel Central recess 7, an elongated pivot element 8 is provided, which is firmly connected to the sole of the shoe 6 and on which a shoe plate 9 is pivotally attached.
  • the shoe plate 9 has connecting elements, such as lugs or rails, which are complementary to the rails 4.
  • this cleat is a straight three-sided prism 9, which is connected at its tip to the swivel element 8.
  • the connection between the prism 9 and the shoe 6 can be realized as a shaft with the aid of a rod 12 shown in FIG. 2, which is guided through corresponding bores in the pivot element 8 and the prism 9.
  • any other connection method can also be used, in particular the sole 6 and the shoe plate 9 can also be produced in one piece from a plastic.
  • a further advantage in the illustrated embodiment results from the fact that the shoe plate 9 does not protrude beyond the sole 6, so that a user can easily move on foot without a bicycle.
  • the shoe plate 9 can also be designed differently, as long as it can be firmly but detachably connected to a Einkastvorrichtug 4 of the pedal and allows the shoe 6 to pivot laterally relative to the shoe plate 9.
  • the direction of the pivoting is indicated by the arrow 10, which indicates a possibility of pivoting the shoe about the plane 11 running vertically to the drawing plate.
  • FIG. 2 shows a view from below of a shoe 6 for use with a pedal according to FIG. 1. Identical features are provided with the same reference numerals.
  • the recess 7 can be clearly seen, in which two opposing abutments are shown by the pivot element 8.
  • the shoe plate 9 is inserted between them, the shoe plate 9 and the pivot element 8 being pivotally connected to one another via the rod 12.
  • this rod 12 can also be replaced in a simple manner if the connection e.g. should solve in the event of a fall.
  • the Pedalkö ⁇ er 2 has the treads 3, which act as stops when the shoes 6, only indicated schematically, settle on them when pivoted.
  • FIG 3 shows a partially sectioned top view of a pedal with shoe latches according to a second exemplary embodiment of the invention.
  • the pedal axis which is shown in FIG Usually articulated to the radially outer end of the crank arm, not shown in the drawings, the pedal axis 1 being rotatably connected to the crank arm.
  • the pedal or transverse axis 1 runs perpendicular to the crank arm.
  • a horizontal tube 21, shown here in the direction of travel is mounted with a bore 23 aligned with the transverse axis for receiving a ball bearing 22.
  • the central tube 21 can rotate freely about the transverse axis 1.
  • the pedal body 2 itself corresponds to the known pedal bodies, i.e. it has two opposing symmetrical treads 24 on which the cyclist can put his foot down. These are drawn as frames in FIG. 3 and have been omitted in FIG. 4 for simplification.
  • the treads 24 each have transverse strips 25 at their ends, on which a fastening device 26 is provided in the center of the central tube 21, which is described in more detail in connection with FIG. 4.
  • FIG. 4 shows a cross-sectional view of one half of this central tube 21 of the pedal according to FIG. 3.
  • the cross strips 25 have inner bearings 31 which protrude into the opposite bores of the central tube 21.
  • the pedal body 2 is rotatable about the axis in the direction of travel, which is indicated by the arrow 32.
  • the transverse strips 25 can be arranged at a distance from the central tube 21 or rest on the front edges of the central tube 21 as not shown in the drawings.
  • the fastening device now has, for example, a spindle 26 which is passed through a bore 33 in the cross bar 25 and on the inside of the tube one end 27 of a spring 28 is fastened.
  • This spring 28 runs inside the central tube 21, which is hollow up to the central bore 23, and is at the other end 29 of said end of the tube Central tube 21 attached.
  • a customary locking bracket 30 is provided, which is movable in the direction of travel via a bearing 34 and into which the heel of a shoe can thus snap.
  • a fixed catch 35 is arranged on the cross bar 25, which picks up the tip of the shoe, so that the pedal can also be used when the pedal is used rotated through 180 degrees.
  • the catches 30 and 35 are complementary to corresponding devices which are provided on the shoes of the user of the bicycle.
  • stops 36 and 37 are provided which limit the lateral pivoting movement of the pedal body 2. For simplification, these are only arranged at the upper end of the central tube 21 in the drawing in FIG. 3. This is sufficient, even if a symmetrical configuration is preferred.
  • the stop 36 prevents the pedal 2 from tilting too much in the direction of the crank arm and the stop 37 prevents the pedal 2 from tilting too far away from the bicycle and away from the crank arm.
  • the possible spring forces can be adjusted per se by selecting the springs 28. There is also the possibility of fine adjustment via said spindle 26 or another device which changes the spring travel.
  • the advantage of this pedal lies in the connection of two functions with few components, namely the functions of snapping a shoe in and resistance to pivoting of the pedals with only two springs opposite the pedal bearing, which can be adjusted with only one screw each.
  • a pedal is specified, whereby the foot can move freely and the driver can always transmit his power, as far as the body's own axes are concerned, perpendicularly to the pedal body and angling of the ankle or knee under load is avoided.
  • This elimination of the angled ankle prevents excessive strain on the knees and ligaments, which are particularly a cyclist problem.
  • the modern pedal systems comparable to a safety binding are difficult to adjust due to the flank tensile forces that arise, since the angulation required there and the resulting forces should not already trigger the binding.
  • the trigger point can now be set considerably more precisely when using the pedals according to the invention, since lateral twisting or pulling can only occur in the event of a fall or for deliberate triggering at a stop.
  • the detents 30 and 35 also referred to as connecting elements, which have been described in connection with the exemplary embodiments of FIGS. 3 to 5, can also be replaced in the embodiment of the invention, for example for trial sports, by, for example, transverse noses or other elevations, which then face complementary recesses in the soles of the shoes.
  • FIG. 5 shows a top view of a pedal with shoe latches according to a third exemplary embodiment of the invention.
  • This pedal is designed similarly to the pedal according to FIG. 3.
  • the cross shaft 1 itself is rotatably supported about its axis 40.
  • the cross shaft 1 has at its end an annular extension 41, through which a hollow tube 42 is inserted, and that is supported in the extension 41.
  • the hollow tube 42 can thus be pivoted about its axis in accordance with the double arrow 10.
  • the pedal strips 43 are fastened to the hollow tube 42, for example inserted into the hollow tube 42, and connected to a pedal surface via longitudinal members 44.
  • the longitudinal member 44 on the inside of the bicycle has a central thickening 45 with a transverse opening 46 in order to be able to pass the transverse shaft 1.
  • the opening 46 which is not directly recognizable in the plan view of FIG. 5, is oval, for example, in the vertical direction, so that the transverse shaft 1 can move in this slot relative to the axis of the hollow tube 42.
  • the thickening 45 forms two with the upper and lower edges of the opening Stops that prevent excessive rotation of the hollow tube 42 in the ring 41 and thus prevent the pedal from tilting too much.
  • the preferably adjustable but otherwise fixed front catch 35 is now placed on the pedals in the direction of travel 32.
  • the rear catch 30 is arranged, which can be tilted about an axis running parallel to the axis 40 via a bearing (not shown in FIG. 5).
  • the user of the pedal can insert his toe into the catch 35 and then the shoe with the aid of fix rear catch 30.
  • the rear catch 30 is fastened in a manner similar to FIG. 4 on a spring not shown in FIG. 5.
  • This embodiment of a pedal according to FIG. 5 has the manufacturing advantage that a single spring is sufficient to implement the function. This single spring extends through the entire hollow tube 21 and the two ends of the rear lever 30 opposite end of the latch lever is attached. The pedals can therefore be used on both sides.
  • the not-used notch 30 forms the abutment for the spring when the heel of a shoe is inserted into the other notch 30.
  • the adjustment of the spring force can be carried out with a single spindle, since this force is the same for the symmetrically arranged catches 30, regardless of a rotation of the pedal by 180 degrees.
