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 to which a tensioning lever is pivotably articulated, a pawl piece being resiliently mounted in the tensioning lever so that it opens when it is opened of the tensioning lever engages on a steep flank of the belt in order to transport it, and a spring-loaded, two-armed backstop is also pivotally articulated on the bottom part and engages with a locking lug provided on one arm on a steep flank of the toothed belt, by pressure on the other arm, the locking lug can be brought out of engagement with the toothed belt against spring force
  • the object of the invention is to ensure safe and easy closing and / or opening of the shoe under a wide variety of external influences, such as wetness, low temperatures or dirt.
  • the shoe should be closed very tightly (usually for the purpose of doing sports). This leads to high tensions on the closure part and, in known embodiments, results in non-functioning and often damage to the same and / or the toothed belt.
  • a toothed belt fastener according to the prior art is disclosed in EP-A1400213 (SIDI), in which a spring-displaceable part which can be brought into engagement with the row of teeth and which is elastically urged by the tensioning lever in the direction of the toothed belt is arranged in the tensioning lever of the mechanism.
  • a further embodiment of such a closure is disclosed in EP-A2-387402, the toothed belt having at least two rows of teeth, one of which mainly cooperates with tensioning the belt (closing the shoe) and the other with the braking means (for opening the closure) .
  • the tensioning lever has a displaceable part in its working area, which represents the positive connection with the toothing of the toothed belt.
  • US-A-3 662435 (ALLSOP) describes in detail a similar locking mechanism, which is a manually movable one-piece cocking lever or a cocking lever has, which is formed from a lever piece, a holding arm and an operating piece for pivotable engagement or non-engagement in the toothed belt.
  • the holding arm is arranged spring-loaded in the direction of the toothed belt and is pivotably mounted on the tensioning lever.
  • this closure has a one-armed lever, by means of which the toothed belt is transported when the tensioning lever is closed. In practice, this closure variant has therefore not been retained.
  • a toothed belt lock has become known from EP-B1-259896 (Raichle), which contains a band-shaped holding element guided around a ski shoe, at the end of which locking notches are arranged, the locking part being pivoted by a pivoting lever, in which one engages in the row of teeth Slider is guided, which is returned to its rest position by spring force during the backward movement of the tensioning lever, and is formed by a releasable backstop.
  • the closure according to the invention has a base part 1 with two correspondingly shaped side walls 1 ', on which a clamping lever 4 consisting of two side walls 4' 'and a back part 4' is pivotably articulated along a pivot axis 5 by means of two rivets 3, which may have a recess 4 ′′′, as shown in FIG. 3, this base part 1 having a projection 2 in the transport direction indicated by the arrow B before and / or after the articulation axis 5 in order to, according to the invention, as in FIGS 2 is shown to create a gap between a toothed belt 16 and this bottom part 1, and the bottom part 1 contains a bore 3 in order to fasten it (eg by means of a rivet) to the shoe upper 23.
  • the tensioning lever 4 can have a recess 4 '' in its back part 4 'and is locked in its closed position by means of inwardly directed knobs 6' on both side cheeks 4 ', which in the last section of the closing movement of the tensioning lever 4 engage in curved grooves 6 ', which are formed on both side walls 1' of the bottom part 1 and at the end of which there are bores 6 "in which the corresponding knobs 6 engage when the tensioning lever 4 is in the closed position.
  • the tensioning lever 4 contains a two-armed pawl piece 7, which is pivoted at a distance from the articulation axis 5 in the tensioning lever 4 between its side cheeks 4 ′′ about a pivot axis 8 and acts in a position which is controlled by a spring 9 which is recessed in a Seat is arranged on an arm 7 'of the pawl piece 7 and acts between this arm and the inner surface of the back part 4' of the tensioning lever 4.
  • the pawl piece 7 is formed from the position shown in Fig. 2 to one in the back part 4 'of the tensioning lever 4 Stop 10, as can be seen in FIG. 1, can be rotated by a certain angle and can engage by means of the second arm 7 "on a steep flank 17 in the toothed belt 16.
  • the spring 9 is then advantageously a helical 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 by means of a pin 12, which acts on this bottom part by means of a spring 14, so that the sperm 13, 13 'of the backstop 11 located on the arm located in the transport direction B after the pin 12 on the toothed belt 16 are pressed, this spring being arranged on an axial seat of the backstop 11 and acting between the backstop 11 and one of the side walls 1 'of the bottom part 1.
  • a toothed belt 16 is guided through the base part 1, between its base and the backstop 11, and between the two side cheeks 4 ′′ of the tensioning lever 1, the teeth of which each have a steep 17 and a flat 17 ′ flank, this toothed belt 16 being on its end in the direction of the upper 23, as shown in FIGS. 4 to 8, can have different hooking means 18, 18 ', 19, 19', 20, 20 '21, 21' 22, 22 'assigned to one another and its direction of transport when closing the shoe in Figures 1 and 2 is indicated by the arrow B.
  • the belt 16 is inserted into the bottom part 1 between its base and the pawl piece 7 of the tensioning lever 4 until the toothed part of the belt 16 engages in the toothed part 13, 13 'of the backstop 11. If the tensioning lever 4 is pivoted in the direction of arrow A about the articulation axis 5 from the closed position to the maximum open position, this movement, in which at the same time the pawl piece 7 engaging with the arm 7 "in the toothed belt 16 until touching the Stop 10 rotated about the articulation axis 8, the toothed belt 16 transported in the direction of arrow B and thus transforming the pivoting movement of the tensioning lever 4 and the pawl piece 7 into a linear translation movement of the toothed belt 16.
  • tensioning lever 4 Such pivoting movements of the tensioning lever 4 are carried out until the shoe is firmly closed, the construction according to the invention ensuring that at least one tooth per opening and closing of the tensioning lever 4 is overcome when the belt 16 is moved.
  • the tensioning lever 4 is brought into its completely closed position, in the associated latching means 6, 6 ', 6 "preventing the tensioning lever 4 from being opened accidentally, and the tensioning lever 4 in this position covers the mechanism against ingress of foreign bodies a further embodiment, not shown here, the tensioning lever 4 can additionally by means of a clamp lying behind the closure in the transport direction B, which is movable in the longitudinal direction on the toothed belt 16 or fixedly attached to the bottom part 1, additionally secured against accidental opening.
  • the tensioning lever 4 can have a recess 4 ′′ 'shown in FIG. 3, which allows access to release the backstop 11 without opening the tensioning lever 4.
  • the pawl piece 7 can have one arm in the direction of the work area and the Spring 9 can be designed as a spiral spring around the axis 8, which again achieves the mode of operation according to the invention.
  • a projection 2 is formed, over which the toothed belt 16 slides so that between the base part 1 and the belt 16 there is a space for the cam piece of the pawl piece to spring back by bending the toothed belt 16, and to ensure a positive fit 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.
