Definitions

  • the present invention relates to a sports shoe and in particular a ski shoe.
  • the present invention is based on the object of creating a sports shoe, in particular a ski shoe, of this type, the closing device of which, with the simplest possible structure, enables the shoe to be closed and opened quickly.
  • Closing the shoe i.e. the strap or cable is tensioned by swiveling the tensioning lever back and forth, and thanks to the special design of the coupling between the tensioning lever and the drive shaft, practically continuous tensioning is possible.
  • the shoe is opened, ie the band or cable is loosened in a simple manner by moving the Housing, the displacement of which results in a release of the clutch and thus a release of the winding drum.
  • the two shaft parts can now be easily moved away from one another by unwinding the tape or cable from the winding drum.
  • Fig. 1 the rear part of a ski boot 1 is indicated by dashed lines, the shaft of which is designated by 2 and the sole of which is designated by 3.
  • the upper shaft region 4 is formed by a front shaft part 5 and a rear shaft part 6.
  • the rear shaft part 6 is connected in an articulated manner to the lower part of the shoe shell by means of two joints 7, 7 ′, which lie opposite one another with respect to the middle plane of the shoe.
  • the rear shaft part 6 spoker
  • the padded inner shoe arranged in the interior of the shoe shell is not shown in FIG. 1.
  • the two shaft parts 5 and 6 can be connected to one another by means of a closing device designated by 8.
  • This closing device 8 has a tensioning device 9 arranged on the rear shaft part 6 and a band 10 which can be tensioned by the latter and which is anchored at its ends to the front shaft part 5 at two points which lie opposite one another with respect to the center plane of the shoe.
  • the band 10 has at its ends (of which only one end 10a is visible in FIG. 1) a loop through which an anchoring pin 11 passes, which in a manner not shown in the manner of a snap connection to the front Shaft part 5 connected is.
  • the tensioning device 9 has an elongated housing 12 which in its longitudinal direction, i.e. in the direction of arrow A, is arranged displaceably on the rear shaft part 6.
  • a bellows 15 is arranged as a cover between the housing 12 and an anchoring plate 14 which is fastened to the rear shaft part 6.
  • a winding drum 16 for the tape 10 is arranged in the interior of the housing 12 and is rotatably mounted in the housing 12 by means of bearing parts 17, 17 '(FIGS. 4 and 6).
  • the winding drum 16 is secured against being moved along with the housing 12, as will be explained in more detail below.
  • This displacement of the housing 12 takes place against the action of a compression spring 18 which is arranged between the upper bearing part 17 and the housing cover 12a.
  • the take-up drum 16 is provided with a longitudinal slot 19 through which the band 10 extends.
  • the band 10 continues through lateral longitudinal slots 20 and 21 in the housing 12.
  • a hollow drive shaft 22 which is arranged coaxially with the winding drum 16 and below it.
  • This drive shaft 22 is rotatably mounted in the housing 12 and can also be displaced therewith.
  • the coupling between the drive shaft 22 and the winding drum 16 takes place via a switchable spline coupling 23 (also known in specialist circles as the Jaccard coupling).
  • the inner part 23a of this coupling 23 has an external toothing and is connected to the winding drum 16, ie to the lower bearing part thereof 17 'formed in one piece.
  • the other coupling part 23b which accordingly has internal teeth, sits on the drive shaft 22 and rotates with the latter.
  • a backstop 24 for the drive shaft 22 is arranged in the housing 12, which is designed as a clamping roller freewheel.
  • the non-rotatably connected to the housing 12 outer part of this backstop 24 is designated 24a, while the inner part seated on the drive shaft 22 is designated 24b.
  • the backstop 24 is preferably designed as an external freewheel.
  • a tensioning lever 25 is provided, which is displaceable with the housing 12.
  • This clamping lever the handle part of which is designated 25a, can be pivoted back and forth between two end positions in the direction of arrow B (FIG. 1).
  • the tensioning lever 25 rests on the outside of the rear shaft part 6, a spring (not shown) ensuring that the tensioning lever 25 remains in this rest position.
  • the other end position of the tensioning lever 25 is indicated by dash-dotted lines in FIG. 1 and designated 25 '.
  • the tensioning lever 25 is connected to the drive shaft 22 via a clamping roller one-way clutch 26.
  • this clamping roller freewheel clutch 26 which is preferably designed as an external freewheel, is designated by 26 a and is connected to the tensioning lever 25 in a rotationally fixed manner.
  • the inner part of this clutch, which sits on the drive shaft 22, is designated by 26b.
  • the backstop 24 designed as a pinch roller freewheel and the pinch roller freewheel clutch 26 are of a known type per se. For this reason, no further description of the structure and mode of operation of these two components is given.
  • a support bolt 27 extends through the hollow drive shaft 22 and is in contact at the upper end 27a with the winding drum 16 or the bearing part 17 '.
  • the support bolt 27 is fastened in the anchoring plate 14 at its lower end 27b.
  • the position of the support bolt 27 with respect to the anchoring plate 14 can be adjusted by means of an adjusting screw 28 which is screwed into a sleeve 14a inserted in the anchoring plate 14. The operation of this support bolt 27 will be explained.
  • An L-shaped release lever 29 is arranged above the housing 12 and is mounted in the rear shaft part 6 so that it can pivot about an axis 29a.
  • the pivot axis 29a extends substantially at right angles to the direction of displacement A of the housing 12.
  • the release lever 29 is in the direction of the arrow C (FIG. 1) between two end positions swiveling out.
  • the rest position which is shown in Fig. 1 with solid lines, the trigger lever 29 rests on the shoe.
  • the trigger lever 29 acts on the cover 12a of the housing 12 and displaces this housing 12 together with the drive shaft 22, the backstop 24, the tensioning lever 25 and the pinch roller overrunning clutch 26 against the action of the compression spring 18 down (in the direction of arrow A).
  • the release lever 29 is reset when the housing 12 is reset by the compression spring 18.
  • the starting point is the open ski boot 1.
  • the rear shaft part 6 is folded completely backwards and the band 10 is completely unwound from the winding drum 16.
  • the housing 12 is held in its upper end position by the compression spring 18 (FIGS. 1, 2 and 4). This means that the two parts 23a, 23b of the spline coupling 23 are in engagement with one another.
  • the winding of the band 10 on the winding drum 16 has the result that the band sections leading to the front shaft part 5 are shortened.
  • the rear shaft part 6 is now pulled evenly against the front shaft part 5 and placed against the lower leg of the wearer.
  • the pinch roller one-way clutch 26 enables a very fine adjustment of the tension in the belt 10.
  • the backstop 24 prevents the shaft 22 or the winding drum 16 from turning back.
  • the wearer If the wearer now wants to open the shoe in whole or in part, he presses the upper end 29b of the release lever 29 by hand or with the ski pole and presses it down in the direction of arrow C (FIG. 1) into the release position 29 '.
  • the housing 12 together with the drive shaft 22, the backstop 24, the tensioning lever 25 and the pinch roller overrunning clutch 26 are shifted downward in the direction of arrow A (FIGS. 1, 2 and 6).
  • the compression spring 18 is compressed (Fig. 3 and 6).
  • the support bolt 27 fastened to the rear shaft part 6 via the anchoring plate 14 and which, as already mentioned, acts on the unwinding drum 16 or its bearing part 17 'prevents the take-up drum 16 from being carried along during this downward movement of the housing 12.
  • the winding drum 16 remains in it Location.
  • This relative movement between the winding drum 16 and the housing 12 together with the components 22, 23b, 24, 25 and 26 which can also be displaced therewith has the result that the two parts 23a, 23b of the spline coupling 23 separate from one another (FIG. 6), ie the coupling 23 is disengaged.
  • the take-up drum 16 can now rotate freely, which enables the tape 10 to be unwound.
  • a movement of the rear shaft part 6 backwards is necessary, which is caused by hand or by a corresponding movement of the lower leg of the wearer.
  • the spring 18 also serves to hold the two parts 23a, 23b of the spline coupling 23 in engagement with one another in the tensioned state of the tensioning device 9.
  • FIGS. 7-9 show a second embodiment of the clamping device 9, the same reference numerals being used in those FIGS. 7-9 for those components which correspond to components of the embodiment according to FIGS. 4-6 as in FIGS. 4-6 .
  • the second embodiment according to FIGS. 7-9 differs from the embodiment shown in FIGS. 4-6 by a different type of backstop 24 for the shaft 22 and another coupling between the tensioning lever 25 and the shaft 22.
  • a backstop 30 is arranged between the shaft 22 and the housing 12, which has a part 30a which is non-rotatably connected to the housing and a part 30b which is non-rotatably connected to the shaft 22.
  • the latter is displaceable in the axial direction of the shaft 22 and is pressed against the coupling part 30a fixed to the housing by means of a compression spring 31.
  • the two coupling parts 30a and 30b have toothings 32 and 33 on their mutually opposite end faces, which engage in one another under the action of the compression spring 31. These toothings 32, 33 are designed such that when the coupling part 30b rotates in one direction they separate from one another (free-wheeling action), but prevent rotation in the opposite direction.
  • the backstop 30 prevents the shaft 22 from turning back when the tensioning lever 25, as already described earlier, is moved back from the end position 25 ′ shown in dashed lines in FIG. 1 to the rest position.
  • the backstop 30 is not effective, because in this direction of rotation the coupling part 30b which can be displaced in the axial direction of the shaft 22 is pushed back against the action of the compression spring 31 and the teeth 32, 33 do not have a blocking effect, but continue to work together.
  • the clutch 34 between the tensioning lever 25 and the shaft 22 is constructed in the same way as the backstop 30 just described.
  • the one coupling part 34a of the clutch 34 is rotatably mounted with the tensioning lever 25.
  • the other coupling part 34b is connected in a rotationally fixed manner to the shaft 22, but is mounted on the shaft 22 so as to be displaceable in its axial direction.
  • the coupling part 34b is pressed against the other coupling part 34a by a compression spring 35 which is supported on the housing 12.
  • the two coupling parts 34a and 34b are provided with toothings 32, 33 on their opposite ends.
  • the embodiments of the tensioning device 9 shown have the following advantages: When using a pinch roller one-way clutch 26 between tensioning lever 25 and drive shaft 22 (FIGS. 4-6), fine adjustment of the tension in band 10 is possible. Since the winding drum 16 always assumes the same position with respect to the shaft parts 5, 6 when winding and unwinding the tape 10, the tape travel 10 does not change when tensioning or releasing. As a result of the arrangement of the winding drum 16 above the tensioning lever 25 and the drive shaft 22, the winding drum 16 can be arranged as high as possible, ie as close as possible to the upper edge of the rear shaft part 6. The two shaft parts 5, 6 can thus be closed far up on the shaft.
