Definitions

  • the invention relates to a fitting part for the sole of a cycling race shoe, which can be fixed longitudinally on the sole by means of at least one screw which penetrates a hole in the fitting part and can be screwed into a threaded insert in the sole, and which has a transverse groove for engagement with the pedal bridge.
  • Fitting parts of the type specified above are firmly connected to the sole of the racing shoe and serve to connect the racing shoe to the pedal of the racing bike in such a way that the racing driver is too has firm contact with the pedal at all times. Since every cyclist maintains an individual foot position relative to the pedal for optimal power development, it is common to adjust the fitting parts on the sole of the racing shoe both lengthways and to a certain extent rotatable about an axis running perpendicular to the sole.
  • the well-known fittings that have such double adjustability enable are structurally relatively expensive because they require a twistable and displaceable intermediate piece and make a complex sole training necessary.
  • the invention is therefore based on the object of providing a fitting part of the type described which is of simpler design and does not have a disadvantageous effect on the performance even with a slight deviation from the optimal rotational position.
  • flanks of the transverse groove, with which the pedal web interacts are designed to be elastically flexible.
  • the elastic resilience of the transverse groove can be achieved in one embodiment in that the transverse groove is formed in an insert which is elastically resiliently mounted in a recess in the fitting part.
  • the transverse groove is formed in an insert which itself is made of an elastically flexible material, e.g. Rubber, is and is fixed in the fitting part.
  • the transverse groove does not rigidly maintain its alignment after being connected to the pedal bridge, but rather adapts to the forces that arise by pivoting about an axis that is approximately perpendicular to the sole, and therefore 1 automatically moves towards the optimal rotational position a. Therefore, even if the optimum rotational position is not exactly reached when the fitting part is fastened, it is not necessary to make a rotational correction for this because the deviation is due to the elastic flexibility the groove flanks is balanced. It is therefore possible to dispense with the fact that the fitting part can be largely rotated and the structurally complex design associated therewith and instead essentially only provides for longitudinal adjustability, which at most allows a slight rotation.
  • the solution according to the invention also has a significant advantage in connection with such fitting parts that are adjustable both lengthways and rotationally.
  • the cyclist's foot is not always held in the same position relative to the pedal, but is pivoted about an axis approximately perpendicular to the sole and the pedal axis. If the pedal bridge fits relatively precisely into the transverse groove of the fitting part, this pivoting is prevented, which in the same way as explained above has a performance-reducing and damaging effect on joints and ligaments.
  • the transverse groove is kept wider than the pedal bridge so that the mentioned pivoting is possible, the pedal bridge shakes in the transverse groove and the racing driver has the feeling that he is not firmly connected to the pedal.
  • the transverse groove is provided directly in the insert formed from an elastic material, which is fastened, for example embedded, in the fitting part, then it is expedient to cover the flanks of the transverse groove with a hard material so that the elastically flexible material is not subject to wear.
  • the insert can be directly connected to the fitting part and the metal protecting the groove flanks, for example vulcanized or vulcanized on.
  • the insert is interchangeably arranged in a recess in the fitting part.
  • the essentially rectangular fitting part 1 is adapted to the curved shape of the sole 2 with its contact surface with which it is intended to bear against a sole 2 of a cycling racing shoe (not shown) (cf. FIGS. 2, 3). It consists of a solid plastic, e.g. Polyamide or polystyrene.
  • a transverse recess 3 is formed, which has the shape of a dovetail groove in cross section and in which an insert 4 made of rubber or a similar elastic material is fastened by vulcanization.
  • the insert 4 has a transverse groove 5 running in its longitudinal direction and thus transversely to the longitudinal direction of the fitting part 1, which is formed by an essentially U-shaped profile 6 made of thin sheet steel.
  • the U-profile 6 also encompasses part of the underside of the insert 4, as can be seen in FIG. 2, with lateral lugs on its legs and is vulcanized directly with the insert 4.
  • the transverse groove 5 is open to the two sides of the fitting part 1 and, moreover, is adapted to the dimensions of a pedal web, not shown, so that it can engage properly.
  • two elongated holes 10 are formed symmetrically to the center line thereof, which are offset at 11 by screws 12 to support the head.
  • the screws 12 can be screwed into a threaded insert 13, which is embedded in the sole 2.
  • the width of the elongated holes 10 corresponds essentially to the diameter of the screws 12, but is adjusted so that there is a slight play, which allows a certain amount of rotation of the fitting part 1 before tightening the screws 12.
  • the fitting part 1 is immovably connected to the sole 2.
  • it can be considered to provide tips or the like in the contact surface towards the sole, which press into the sole material when the screws 12 are tightened and result in a positive fit.
  • the U-profile 6 forming the transverse groove 5 is elastically mounted in the fitting part 1 via the insert 4, it can be locally in one under the forces occurring when driving, in particular when pivoting about an axis approximately perpendicular to the drawing plane in FIG. 1 to yield to a certain extent.
  • the compliance is greater or less. It is therefore possible to firmly insert the pedal web (not shown) into the transverse groove 5, so that the driver always has close contact with the pedal, but nevertheless to give the foot a certain freedom of movement around the axis perpendicular to the sole 2, which is necessary for a crank revolution.
  • the fitting part 1 'according to FIGS. 3, 4 differs only with regard to the elastic mounting of the insert 4' forming the groove 5 'from the embodiment according to FIGS. 1, 2.
  • the insert 4' which here consists of a hard and relative unyielding material, e.g. Aluminum, consists, itself contains the transverse groove 5 'and is adapted in terms of its cross-sectional shape to the dovetail-shaped recess 3'. However, its cross-sectional size is selected so that between its two flanks and the flanks of the recess 3 'there are gaps 7', in which leaf springs 8 'are inserted with prestress.
  • the leaf springs 8 ' have corrugations near the ends of the recess 3', which are shown in more detail in FIG. 4.
  • the insert 4 ' can be prevented from slipping out laterally in the region of the ends of the recess 3' by holding elements, not shown, without its flexible storage caused by the leaf springs 8 'being hindered thereby.
