Definitions

  • the present invention relates to a central closure for shoes according to the preamble of claim 1.
  • Such a central lock designed as a rotary lock is known from EP-0 393 380 B1.
  • the limitation of the number of revolutions of the sheave to a little less than two full revolutions is there due to the application of the traction sheave principle.
  • One drag pulley is formed by the rope pulley. This has a driver which, after about one revolution, can strike a rotatable arm, which embodies the second drag disc, and which can strike a housing edge with a stop projection. Small structural dimensions are desirable, even if a long cable route is necessary to close the shoe.
  • the diameter of the rope sheave must be chosen according to the rope path and the possible, not quite two complete turns of the rope sheave. For large rope routes, the diameter of the rope sheave should therefore be chosen accordingly. In this known device, the freedom to choose the dimensions of this device is therefore greatly restricted.
  • the number of revolutions of the rope sheave could be increased by using additional drag disks, so that a larger rope path could be managed by increasing the number of turns on the rope sheave.
  • this would require a larger construction volume corresponding to the thickness of the additional drag disks.
  • EP-A-255 869 discloses a twist lock for a sports shoe, in particular a ski boot, in which the range of rotation of the rope pulley driven by a planetary gear is limited.
  • a not-closed circular groove in the housing base is provided for the limitation in a rotation range of not quite 360 °, in which a nipple engages.
  • a corresponding 1.5-turn spiral groove is provided in the housing base, in which the nipple engages.
  • the nipple in the sheave is held to be movable to a limited extent in the radial direction.
  • a relatively thick housing base must therefore be used in order to be able to produce the groove sufficiently deep, and a guide for the nipple must be able to be incorporated in the sheave.
  • the object of the present invention is to achieve a central lock of the type mentioned at the beginning, ie with a limitation of the number of revolutions of the rope sheave, to improve so that an increase in the number of revolutions of the rope sheave to be limited is made possible without increasing the construction volume.
  • the choice of the transmission ratio of the transmission and the arrangement of the stop (s) make it possible in a simple manner to make the number of revolutions of the sheave relatively large regardless of the external dimensions Ranges, for example in a ratio between 2: 1 to 10: 1.
  • a predetermined central lock can be produced with gear ratios adapted to the respective intended use, without any other structural changes being necessary.
  • Fig. 1 is a central closure for shoes, especially for sports, leisure or rehabilitation shoes, from the side in cross section - i.e. in a section through the central axis - shown, which has a housing part 1 formed as a flat housing shell with a circular recess 2 for receiving a rope pulley 3.
  • the rope sheave 3 can be driven via a gear mechanism which is provided between the rope sheave 3 and an externally actuatable rotary member 33 or another actuating member, for example a lever or lever system.
  • a transmission is preferably used, as described in the older patent DE 42 40 916 C1 of December 4, 1992.
  • the present embodiment according to the invention is not limited to the combination with this type of transmission.
  • a flat, disk-shaped cavity 40 is provided, into which an axial extension of the sheave 3 formed as a pinion 41 with teeth 41a projects.
  • the vertical housing inner wall of the cavity 40 is provided with a circular toothing 42a in the form of an internal ring gear 42.
  • a gear 43 meshing with these two gear parts 41, 42 is arranged with the same module as the other two gear parts 41, 42 and through the underside 44 of the pulley 3 and the inner bottom surface 45 of the bottom 8 guided freely.
  • a stop 46 for example a pin molded onto or inserted into the base 8, which protrudes into the circular path on which the gear 43 rotates and thus limits its range of motion in both directions of rotation.
  • the number of revolutions of the rope pulley 3 is predetermined or calculable in accordance with the gear ratio of the gear comprising pinion 41, internal ring gear 42 or toothing 42a and gear 43 as well as the arrangement of the stop 46 and can therefore be adapted to the given requirements.
  • the pitch circle diameter of the pinion 41 and the gear 43 and / or according to the length of the circular path blocked by the stop 46 for the gear 43 it is possible to determine the number of revolutions of the rope pulley 3 or to adapt it to specific requirements.
  • the pitch circle diameter of the pinion 41 or the gear 43 corresponds to the product of the module (measured for example in "mm") and the number of teeth.
  • the transmission according to the invention intended to limit the number of revolutions of the rope pulley 3, is in principle a planetary gear, the pinion 41 forming the sun gear and the freewheeling gear 43 forming the planet gear.
  • Fig. 3 shows the position of the transmission after rotation of the pinion 41 by 180 °.
  • Ü 1 + Number of teeth outer wheel Number of teeth inner wheel of 5 the gear 43 has moved further by 36 °.
  • the gear 43 When the pinion 41 continues to rotate, the gear 43 finally comes to the stop 46 after four full rotations, as shown in FIG. 4.
  • the gear 43 has moved 288 ° on its circular path.
  • the range of motion of the gear 43 can be further limited in a simple manner by as shown in dashed lines in FIGS. 2 to 4, a second stop 46 'is provided.
  • several plug openings can be present in the bottom 8 of the housing part 1 at different angular distances from one another, into which, depending on the desired limitation of the number of revolutions of the sheave 3, further pins 46 'can be inserted.
  • stops 46, 46 ' it is also possible to provide only one stop which extends over a desired angular range to be blocked, or a plurality of such stops are attached. In this way, by selecting the stops 46, 46 ', etc., a large range of possible rotation speeds of the pulley 3 can be set without changing the dimensions of the gear comprising the pinion 41, the internal ring gear 42 and the gear 43.
  • the pinion 41 is arranged in a fixed manner, for example by a part of the housing part 1 itself or non-rotatably attached to it.
  • the gear 43 is driven via the toothing 42b provided on the rope pulley 3 in the form of an internal ring gear 42.
  • the toothing 42b is not completely formed here and the non-toothed section 48 (FIG. 6) which has an inwardly projecting web 47 forms the stop 46 for limiting the path of the gear 43.
  • the size of the section 48 corresponds here to the blocking of a complete revolution of the rope sheave 3.
  • the relative path from the pinion 41 to the rope sheave 3 reaches 270 ° here.
  • the desired number of revolutions of the rope sheave 3 can thus be set to, for example, two to ten revolutions without increasing the overall volume of the central lock, which is achieved by inserting or providing stops 46, 46 'or the like and / or by changing the diameter of Pinion 41 and toothing 42a or 42b of the internal ring gear 42 is made possible with a corresponding adjustment of the gear 43.
  • the two embodiment variants of the invention are characterized in that at least one tooth groove of the toothing 42a of the immovable Part of the housing part 1 - or the toothing 42b of the movable part - rope pulley 3 - is closed or not, or at least not completely, as a tooth groove.
