Definitions

  • the invention relates to a closure for a shoe, in particular a Sports shoe with a bottom part over which a sawtooth-like toothed belt can be guided and on which a clamping lever is pivotally articulated, a in the clamping lever Pawl piece is resiliently mounted so that it opens on a steep when opening the clamping lever Flank of the belt engages to transport it, and also on the bottom part Spring-loaded, two-armed backstop is pivotally articulated with one on one Arm provided locking lug attacks on a steep flank of the toothed belt, being by Pushing the other arm against the locking lug against spring force out of engagement with the toothed belt is feasible
  • the object of the invention is a safe and easy closing and / or opening the Shoes under various external influences, such as wetness, low temperatures or To ensure dirt.
  • the shoe usually for the purpose of sports
  • a toothed belt fastener according to the prior art is in EP-A1-400213 (SIDI) disclosed, wherein in the tensioning lever of the mechanism is displaceable by spring force, with the Row of teeth can be brought into engagement part which is elastically in by the clamping lever Is pushed towards the timing belt.
  • US-A-3 662435 (ALLSOP) describes in detail a similar locking mechanism, the one manually movable one-piece clamping lever or a clamping lever has that of a lever piece, a holding arm and an operation piece to one pivotable engagement or non-engagement is formed in the toothed belt.
  • the holding arm is arranged spring-loaded in the direction of the toothed belt and pivotally mounted on the tensioning lever.
  • this closure has a generic character a one-armed lever, by means of which the toothed belt when closing the tensioning lever is transported. In practice, this closure variant has therefore not proven itself.
  • a toothed belt lock has become known from EP-B1-259896 (Raichle), which contains a band-shaped holding element guided around a ski boot, at the end of the latter Notches are arranged, the closure part by a pivotable clamping lever, in which a slide engaging in the row of teeth is guided, which during the backward movement the clamping lever is returned to its rest position by spring force, and by a releasable backstop is formed.
  • the closure according to the invention has a bottom part 1 two correspondingly shaped side walls 1 'on which one of two side walls 4' ' and a back part 4 'of existing clamping lever 4 along an articulation axis 5 by means of two Rivets is pivotally articulated, which, as shown in FIG. 3, may have a recess 4 '' ', this bottom part 1 in the direction indicated by the arrow B.
  • Transport direction before and / or after the articulation axis 5 has a projection 2 to according to the invention, as shown in Figures 1 and 2, a space between one To produce timing belt 16 and this bottom part 1, and the bottom part 1 has a bore 3rd contains in order to fix it (e.g.
  • tension lever 4 can be in its Back part 4 'have a recess 4' '' and is in its closed position by means of locked on both side cheeks 4 '', inwardly directed knobs 6, which in last section of the closing movement of the tensioning lever 4 in curved grooves 6 ' engage, which are formed on both side walls 1 'of the bottom part 1 and on their End holes 6 '' are in which the corresponding knobs 6 when closed Engage the position of the clamping lever 4.
  • the tensioning lever 4 contains a two-armed pawl piece 7, which is at a distance from the articulation axis 5 in the tensioning lever 4 between its side cheeks 4 ′′ about a pivot axis 8 is pivoted and acts in a position controlled by a spring 9, which is arranged in a recessed seat on an arm 7 'of the jack piece 7 and acts between this arm and the inner surface of the back part 4 'of the clamping lever 4.
  • the Pawl piece 7 is from the position shown in Fig. 2 to one in the back part 4 'of Clamping lever 4 trained stop 10, as can be seen in Fig. 1, to a certain Angle rotatable and can by means of the second arm 7 '' on a steep flank 17 in the Engage toothed belt 16.
  • the spring 9 is then advantageously one Coil spring around the articulation axis 8 of the pawl piece 7 and this either with a shortened arm 7 'or one arm.
  • a two-armed backstop 11 is arranged on the base part 1 by means of a pin 12, which acts on this bottom part by means of a spring 14, so that on the in the transport direction B located after the pin 12 arm sperm 13, 13 'of the backstop 11 are pressed onto the toothed belt 16, this spring having an axial seat the backstop 11 is arranged and between the backstop 11 and one of the Side walls 1 'of the bottom part 1 acts.
  • the belt 16 is in the bottom part 1 between its base and the pawl piece 7 of the Tension lever 4 inserted until the toothed part of the belt 16 in the toothed part 13, 13 'of the backstop 11 engages. If the clamping lever 4 in the direction of arrow A around the Articulation axis 5 pivoted from the closed position to the maximum open position with this movement, which is simultaneously the arm 7 '' in the toothed belt 16 engaging pawl 7 until touching the stop 10 around Articulation axis 8 rotated, the toothed belt 16 transported in the direction of arrow B and thus the pivoting movement of the clamping lever 4 and the pawl piece 7 in a linear translation movement of the toothed belt 16 transformed.
  • the tensioning lever 4 can be closed in FIG. 3 seeing recess 4 '' ', which have access to release the backstop 11 without Opening the clamping lever 4 allowed.
  • the jack piece 7 with one arm in the direction of the work area and the spring 9 as a spiral spring around the axis 8 be formed, with which the mode of operation according to the invention is again achieved.
  • FIG. 1 A better engagement of the arm 7 ′′ in the teeth of the toothed belt 16 is shown in FIG the base part of the lying in the transport direction B before and / or after the tensioning lever Bottom part 1 formed a projection 2, over which the toothed belt 16 slides so that between the bottom part 1 and the belt 16 a space for springing back Cam of the pawl piece by bending the toothed belt 16, as well as to ensure positive engagement of the pawl arm 7 ′′ in the toothed belt 16 is generated, without the belt being damaged when the pawl piece 7 is actuated.
  • the spring piece 9 springs back after the end of each tensioning cycle supports or accelerates.
