Definitions

  • the invention relates to a screw cap for a shoe, in particular for a sports shoe, comprising: a housing attachable to the shoe, a rotatably mounted in the housing about an axis tensioning roller on which when tightening the shoe, a tensioning element can be wound, and a rotary knob to the the axle is rotatably mounted on the housing to rotate the tension roller. Furthermore, the invention relates to a shoe with such a rotary closure.
  • a generic rotary closure is for example from the DE 297 01 491 U1 known. Such a rotary closure should on the one hand at the tension of the clamping element (Schnürfaden or wire) by turning the knob with low torque and yet high clamping force allow the lacing of a shoe. On the other hand, a simple relaxation of the clamping element should be possible if the shoe is to be pulled out again.
  • the knob was already pivotally mounted or hinged to the housing, wherein after the pivoting or flaps of the knob a Entrastung the tension roller takes place, so that the tensioned clamping element is de-energized.
  • a push button can be operated to make the unlatching of the tension roller.
  • planetary gears are used to reduce the rotational movement of the rotary knob to achieve said objectives.
  • the invention has the object of providing a rotary closure of the generic type so that on the one hand a light yet strong tension of the clamping element is given when closing the rotary closure and on the other hand, a simple release or unlatching of the clamping element should be possible. At the same time a lightweight construction to be given and a cost-effective production can be realized with few components.
  • the housing preferably has a cylindrical shape.
  • the first locking toothing is preferably introduced on an inner circumference of the housing.
  • This inner circumference is preferably cylindrical.
  • the housing may be made of plastic, wherein the first locking toothing is formed in the material of the housing.
  • the second locking toothing and the tensioning roller are preferably designed as an integral part, in particular as an injection-molded component.
  • the axis of rotation for the relative to the housing movable or rotatably mounted parts is preferably formed by a bolt.
  • a bolt screw
  • the tensioning element is usually a tensioning wire.
  • the two controls are preferably formed as formed on the knob pin-shaped projections, in particular as cylindrically shaped projections.
  • the two controls can be arranged offset in the circumferential direction of the same diameter spaced from the axis lying.
  • the intermediate carrier preferably has two pawls, which are arranged with respect to the axis of rotation diametrically opposite to the intermediate carrier.
  • the at least one pawl can be arranged as radially to the axis of rotation resilient portion on the intermediate carrier.
  • the pawl may continue to extend as a substantially straight, tongue-shaped portion substantially in the circumferential direction of the intermediate carrier.
  • the intermediate carrier advantageously consists of a sheet metal part on which the pawls are formed from the material of the intermediate carrier.
  • the locking lever is preferably made of metal.
  • the locking lever can be arranged in the direction of the axis of rotation projecting bearing pin, which is mounted in a recess in the intermediate carrier.
  • only a single locking lever is preferably arranged on or in the intermediate carrier.
  • the knob can eccentrically at a peripheral point, d. H. spaced from the axis of a recess, in particular a circular recess, have; the intermediate carrier may have on its side facing the knob a mark, wherein the mark is visible through the recess when the knob with its second control in the second link portion of the locking lever and thus the locking lever is in the second pivot position.
  • the marker is preferably formed as a color point.
  • the invention relates to a shoe, in particular a sports shoe, with a rotary closure of the type described.
  • the tensioner roller is provided with a detent (second detent toothing), which allows a rotation in one direction of rotation, but this prevents the engagement of the locking lever.
  • the locking lever is rotatably mounted in the rotatably mounted about the central axis intermediate carrier (support member), namely about a central axis parallel to, but spaced therefrom pivot axis.
  • the intermediate carrier can - for the purpose of tension of the cable - be rotated about the central axis, but only in the clamping direction, which is achieved by pawls (spring tongues), which are arranged radially outwardly resiliently on the intermediate carrier and engage in the first locking toothing (locking profile), the the inside of the housing edge is incorporated.
  • the knob (cover), which is rotatably mounted about the central axis, has the two controls (driving cam).
  • the first control engages when tensioning the cable (rotation in the direction of R1) on the intermediate carrier and rotates this together with locking lever in the closing direction. A reverse rotation of the tension roller is prevented in this case, because the locking portion (hook portion) of the locking lever engages in the second locking teeth of the tension roller, thus preventing the tension roller from rotating backwards.
  • the second blocking element presses against the section-like section (second sliding section) of the blocking lever so that it is rotated about the pivot axis such that the locking section (FIG. Hook portion) is brought out of engagement with the second locking toothing (detent) of the tensioning roller; now The coiled cable can be pulled from the now freely rotatable tension pulley.
  • the geometric design of the parts makes it possible with low torques on the knob, a high tensile stress in the clamping element is achieved when the shoe or the clamping element are tensioned.
  • a screw cap 1 can be seen, which can be attached, for example, on the instep of a shoe to serve to stoke the shoe; but other locations are possible, for. B. in the side area or in the heel area of the shoe.
  • the rotary closure 1 has a cylindrical housing 2, which consists of plastic and is provided on an inner cylindrical surface with a first locking toothing 8.
  • a bolt 16 eg in the form of a screw with end-side closure by a nut
  • a central axis A is formed, by means of which various rotatable parts of the rotary closure 1 are mounted.
  • a tension roller 3 is freely rotatably mounted in the housing 2.
  • a tensioning cable or tensioning element 4 can be wound, in a known manner so that when winding the tightened shoe at the foot of the wearer is tensioned or laced.
  • the tension roller 3 On the upper side of the tension roller 3, a second locking toothing 11 is formed.
  • the tension roller 3 is also made of plastic, so that the locking toothing 11 is formed by the injection molding of the molded part.
  • an intermediate carrier 6 Placed on the tension roller 3 and also mounted about the axis A is an intermediate carrier 6, which consists of a stamped and formed sheet metal part.
  • the intermediate carrier 6 has two pawls 7 which are provided and designed to engage in the first ratchet teeth 8. Accordingly, the intermediate carrier 6 can rotate relative to the housing 2 only in one direction of rotation (namely in the direction of rotation R1, s. Fig. 2 ); the opposite rotation is prevented by the engaging in the first ratchet 8 pawls 7.
  • a locking lever 9 made of metal (steel) is arranged between the tension roller 3 and the intermediate carrier 6, a locking lever 9 made of metal (steel) is arranged.
  • the locking lever has a bearing pin 17, which fits into a recess 18 which is incorporated in the intermediate carrier 6.
  • the rotary knob 5 is rotatably arranged about the axis A.
  • the knob 5 has at its in Fig. 1 underneath underside two in the direction of the axis A and B protruding controls, namely a first control element 12 and a second control element 13.
  • a first control element 12 and a second control element 13 In the illustrations according to the Figures 2 and 3 is the Location of the two controls 12 and 13 to recognize. Both controls are - which is preferred - formed in the embodiment as a cylindrical in the direction of the axis A from the knob 5 projecting portions. They are provided alternatively cooperate with two slide sections 14 and 15 of the locking lever 9.
  • a recess 19 is provided on the intermediate carrier 6, a color marking 20 (s. Fig. 1 ). About these elements can be made immediately visible to the user, whether the rotary closure in the unlatched position, ie the locking lever 9 in the second pivot position II, is. If the color marking 20 visible in the recess 19, the user knows that he has turned the knob 5 far enough in the second direction of rotation R2, so that the unlatching position of the rotary closure is reached.
