Definitions

  • the present invention relates to a shoe with a lacing system comprising at least one shoelace, and a quick-tensioning device for tightening and holding the shoelace, which has a lace reel for winding and tightening the shoelace and a drive reel for driving the lace reel.
  • Such holding and/or clamping devices are known in various designs.
  • the shoelace can be guided through a clamping sleeve, which, after tightening, is slid along the shoelace until the clamping sleeve rests against the last lacing eyelet, from which the shoelace is pulled out.
  • Such clamping eyelets can include a spring-loaded cross slider that can reduce the opening of the clamping eyelet and clamp the shoelace there.
  • clamping clips or other holding devices can be attached to the upper of the shoe, to which the shoelace is clamped once it is tightened.
  • the cord storage for the tensioning cord that is pulled out when tightening the lacing is relatively bulky in order to wind up the required length of cord.
  • the laces must have a relatively long working length, meaning they must have enough extra length to loosen the lacing in the shaft area sufficiently for comfortable entry and exit. This then, conversely, means that when tightening the lacing, the laces must be pulled and taut a considerable distance or length to achieve a good fit. The laces must therefore be pulled out accordingly far and wound onto the cord storage, which makes the cord storage bulky.
  • a snowboard boot is known whose lacing is tightened by means of a lace drum, which is secured against accidental unwinding by a locking latch.
  • a separate pull drum is provided to drive the lace drum.
  • This pull drum has a freewheel opposite the lace drum and is spring-loaded in the freewheel direction, allowing the pull cord to be pulled out several times with a pumping motion to tighten the lacing. Between pumping motions, the spring return mechanism rewinds the pull cord.
  • a similar tensioning system for tightening the laces of a sports shoe is known from the document US 2006/0021204 A1 known, where the pull rope coil, which is a pull-out pull rope can be operated and is connected to the lace reel via a spur gear.
  • the present invention is based on the object of creating an improved shoe of the aforementioned type that avoids the disadvantages of the prior art and advantageously develops them further.
  • the aim is to create a lacing system that is easy to fix and allows for finely controlled tension, with a large or long adjustment range for the laces, without requiring bulky and visually disturbing mechanisms that require a lot of space.
  • the lace spool and the drive spool no longer be designed as a one-piece winch with two winding sections, but rather that they be separated from each other and arranged so that they can rotate relative to each other.
  • a driver device with a freewheel in one direction of rotation is provided between the lace spool and the drive spool. This driver device transmits a rotation of the drive spool in one tensioning direction to the lace spool and allows the drive spool to rotate freely relative to the lace spool in the opposite direction of rotation.
  • the drive spool can be rotated back and forth like a ratchet, in order to continuously twist the lace spool in the desired direction in the tensioning direction and thereby tighten the shoelace.
  • the drive spool can, so to speak, catch the lace. or re-engage, so that a relatively large rotational travel of the lace coil can be achieved with only a limited travel of the drive coil.
  • the lace spool continues to rotate in the same direction—the tensioning direction—while the drive spool rotates intermittently back and forth with a pump-like motion.
  • the lace spool can be held or secured against reversing to prevent the already achieved lace tension from being lost.
  • a flexible tensioning device for example in the form of a tensioning cable, a belt, or a chain, can be provided as the actuating means.
  • This device can be wound around the drive coil so that pulling the tensioning device rotates the drive coil in the tensioning direction.
  • the tensioning device is wound back onto the drive coil, so that the tensioning device can then be pulled off again, allowing the drive coil to rotate in the tensioning direction.
  • actuating means for rotationally driving the drive coil may also be provided, for example, an adjusting lever connected to the drive coil in a rotationally fixed manner, which protrudes outwards on the circumferential side and can be grasped and moved back and forth by a hand or fingers in order to rotate the drive coil back and forth in the manner mentioned or to actuate it intermittently in a rotationally rotating manner.
  • a manually accessible edge bar of the drive coil may also be provided with a knurling to allow the drive wheel to be rotated in the tensioning direction with the thumb or fingertip.
  • a pulling device such as a tensioning cable as the actuating means in order to be able to actuate the drive coil with sufficient force or torque.
  • the separate design of the drive spool and lace spool advantageously also allows for a modular design of the quick-release device and, accordingly, easy adaptability of the quick-release device to different shoe types that require different lacing tensions.
  • the drive spool and/or the lace spool can be easily exchanged to achieve different drum diameter ratios and thus different force transmission ratios.
  • the drive spool and the lace spool can have at least approximately the same drum diameter, so that the shoelace wound onto the lace spool, on the one hand, and the tensioning cable unwinding from the drive spool, on the other hand, have at least approximately the same lever arms, and thus the tensile force on the tensioning cable achieves an approximately equal tensile force on the shoelace.
  • a drive spool with a smaller drum diameter than the lace spool can be selected.
  • the tensioning cable or traction means has an upward direction of actuation - when the shoe is on the ground - or can be pulled upwards away from the shoe can be used to actuate the drive coil.
  • the aforementioned actuation direction of the tensioning cable or traction device can be aligned approximately parallel to the shaft axis of a boot or shoe shaft and/or approximately parallel to the longitudinal axis of the shinbone when the shoe is worn.
  • an outlet opening or removal guide for the traction means can be provided on an upper side of the quick-release device, through which the traction means exits from the drive coil or is held ready on an upper side of the quick-release device, so that a section of the traction means lying ready or standing on the upper side and accessible can be easily grasped by one hand of the shoe wearer.
  • an advantageous development of the invention can provide an elastic retraction device that attempts to rotate the drive spool relative to the lace spool in the freewheeling direction. If the actuating means—for example, the tensioning cable—is released or slackened, the retraction device rotates the drive spool relative to the lace spool, whereby the advantageously provided tensioning cable can be wound around the drive spool, so that the quick-action clamping device is ready for another clamping stroke.
  • the actuating means for example, the tensioning cable
  • the quick-release device can be easily actuated in a pump-like manner in several strokes by tightening and releasing the actuating means coupled to the drive coil in several strokes, whereby when the actuating means is tightened, the drive coil takes the lace coil along in the tensioning direction and when the actuating means is released, the return device turns the drive coil back relative to the lace coil.
  • Such an elastic return device can, for example, engage on the one hand the drive coil and on the other hand the lace coil, for example in the form of a spiral spring, which is suspended on the one hand the drive coil and on the other hand the lace coil.
  • the return device can also have a support point on a housing part in order to The drive coil can be rotated back by being supported on the housing or support part.
  • a spiral spring can be suspended or supported on the one hand on the drive coil and on the other hand on the housing or support part, so that the rotational movement in the freewheeling direction is generated by being supported on the housing or support part.
  • the lace spool is locked in the tensioned rotational position or secured against reversing in the direction of tension, so that the lace spool holds the taut lace in the taut position. Additionally, the taut lace running onto the lace spool can be held before or after the lace spool, blocked, or secured against reversing, allowing the drive spool to be easily reversed relative to the lace spool when the actuator is released or released.
  • a retaining device is assigned to the lace spool, which automatically blocks, fixes, or brakes the lace spool against the rotational tensioning direction and releases it in the rotational tensioning direction.
  • a retaining device is advantageously designed like a backstop brake, which automatically blocks or brakes in the release direction and automatically releases or is free to move in the tensioning direction.
  • the retrieval device has a backstop with free movement in the tensioning direction and a locking direction in the opposite direction of rotation.
  • the retaining device advantageously has a retaining wheel that can be coupled to the lace coil in a rotationally fixed manner and that has non-positive and/or positive retaining means in the area of its outer circumference, which can be brought into engagement with cooperating retaining means on a housing part surrounding the retaining wheel.
  • the retaining wheel can have locking teeth arranged on the circumference, which can be brought into locking engagement with a locking toothing, for example, on the inner circumference of a housing part.
  • a locking toothing must be provided on the outer circumference of the retaining wheel, into which one or more retaining teeth on the surrounding housing part can be brought into engagement.
  • the at least one retaining tooth can be elastically spring-mounted, for example on a spring arm, in order to automatically jump into the locking position and, on the other hand, to be able to slide over one or more locking projections when the lace spool is rotated in the tensioning direction.
  • axially effective retaining means may also be provided.
  • a surrounding housing part could be provided with a toothing on the end face, and the aforementioned retaining wheel could have one or more retaining teeth on an opposite end face section, which can axially engage with the aforementioned retaining toothing.
  • said retaining device is designed separately from the lace reel and can be coupled to the lace reel in a rotationally fixed manner.
  • a releasable coupling is provided between said retaining device and the lace reel to allow the taut shoelace to be released by disengaging the lace reel from the retaining device.
  • an axially operable or axially movable coupling is provided between said retaining wheel and the lace spool, wherein such an axially operable coupling can be designed, for example, in the form of a claw coupling, which can comprise axially projecting and recessed coupling projections and recesses on said retaining wheel on the one hand and an end face of the lace spool on the other hand.
  • spur gears on the retaining wheel and the lace coil which can be brought into engagement and disengaged by axially adjusting the lace coil and the retaining device relative to each other.
  • the retaining device can be released and the lace coil released in other ways.
  • the retaining device itself possibly together with the lace coil, can be axially adjusted relative to a support or housing part to disengage the locking pawls and the associated locking contours, allowing the retaining device to rotate together with the lace coil.
  • an axially adjustable decoupler for example in the form of a wedge, could disengage and/or engage a spring-loaded latch arm to unlock or lock the retaining device.
  • Such an actuator or decoupler could also have a different actuation direction, for example, be radially depressible to decouple or unlock and lock the retaining device.
  • a relatively large-surface actuating element for unlocking or uncoupling can be provided without requiring a bulky design of the quick-release device.
  • the actuating element can be mounted on the front side in front of the drive coil and/or the lace coil on an accessible front side of the quick-release device and, for example, can have a diameter substantially corresponding to the diameter of the lace coil and/or drive coil.
  • the actuating direction is approximately perpendicular to the surface of the upper shoe, in particular approximately perpendicular to the shinbone, making it intuitive for the user to operate or unlock the quick-release device.
  • Shinbone to be designed to be operable, for example to be designed to be pressed in like a release button or to be designed to be pulled out or swung out like a latch.
  • the backstop can also comprise a retaining unit that acts directly on the shoelace, for example in the form of a rope or lace clamp that allows the shoelace to pass through in the tensioning direction but blocks it from moving back in the opposite direction.
  • a retaining unit can comprise two clamping jaws that define a pull-through gap between them and can be provided with a tooth-like clamping profile on the facing flanks.
  • the clamping jaws can be rigidly arranged or, alternatively, can be movable towards and away from each other, for example in conjunction with a pre-tensioning device that presses the clamping jaws towards each other.
  • the movable clamping jaws can open, while in the opposite direction the friction of the lace and/or the pre-tension presses the clamping jaws together, thereby securing the rope.
  • the clamping jaws can be pivoted, preferably around pivot axes that are offset towards the inlet side, so that self-clamping occurs when the rope tries to run back due to the tension.
  • Such a backstop acting on the shoelace itself can relieve the lace reel when the lacing is fully laced, but also during the pumping movements of the drive reel, since the lace reel itself and the retaining device associated with it do not have to absorb the entire lace tension.
  • the unlocking device for unlocking the retaining device is designed to be axially actuated, i.e. actuation takes place approximately parallel to the axis of rotation the lace coil.
  • the release mechanism can have an actuation button that can be pressed in parallel to the rotational axis of the lace coil or pushed toward the shoe upper or upper shoe and/or pulled out in the opposite direction or pulled away from the upper or upper shoe to unlock the retention device.
  • Such an actuation button can also be actuated tangentially to the shoe upper or upper shoe, for example, horizontally in front of the instep or shin.
  • Such an actuation direction perpendicular to the shin or perpendicular to the foot allows intuitive operation of the quick-release device.
  • the shoe 1 comprises an upper shoe 2 which is arranged on a sole 3 and has a lacing 4.
  • Said lacing 4 can comprise a lacing section 4a, for example, in the area of an instep zone of the upper shoe 2. If the shoe 1 is designed in the form of a boot with a shaft 7, the lacing 4 can also comprise a lacing section 4b in the area of the shaft 2—alternatively or in addition to the lacing section 4a in the instep zone.
  • the lacing 4 can comprise a common lace 8 passing through all lacing sections 4a, 4b.
  • different lacing sections 4a, 4b can also be laced with separate laces, as is the case, for example, Figure 1 according to which a first lace 8a laces the lacing section 4a in the instep zone and a second lace 8b laces the lacing section 4b on the shaft 2.
  • a quick-tensioning device 9 is provided for tightening the lacing 4 and thus for narrowing the widening section 5, by means of which the lace(s) 8 of the lacing 4 can be tightened and also stowed away.
  • the quick-tensioning device 9 comprises a lace reel 10 onto which the lace(s) 8 can be wound and thus tensioned or tightened, cf. Fig. 3 and Fig. 4
  • the lace reel 10 can be designed like a cable drum and have a drum body defined at its axial end regions by two flanges to form a winding area for the shoelace(s) 8.
  • the shoelace 8 can be attached or fastened to the drum body or to the side flanges, for example, threaded through a hole and secured by a knot. Alternatively, a sufficient wrapping with several winding turns may be sufficient to hold the shoelace on the lace reel 10.
  • the said lace spool 10 can be held or mounted on a support part 12 of the quick-release device 9 so as to be rotatable about a rotation axis 11, wherein the said rotation axis 11 can extend approximately perpendicular to the surface of the upper shoe 2, cf. Figures 1 , 3 and 4 .
  • the axis of rotation 11 can be aligned approximately perpendicular to a shaft section or to a shin section surrounded by it, cf. Figures 1 , 3 and 4 in order to be able to operate the quick-release device 9 by pulling a tensioning cable 13 upwards, as will be explained later.
  • the quick-release device with the mentioned axis of rotation 11 can also be aligned tangentially to the surface of the upper shoe 2, in particular tangentially in front of a shaft section or a shin section surrounded by it, that is to say in comparison to the mentioned Figures 1 , 3 and 4 be positioned rotated by 90°.
  • Such a rotated arrangement of the quick-release device 9 shows the Figure 8 , whereby in this case too, the said axis of rotation 11 can be arranged horizontally in order to be able to actuate the quick-release device 9 by pulling up the tensioning cable 13.
  • Such a two-sided mounting arrangement is lighter in construction and can support the rotating spools or their rotational axes more stably, since, unlike a cantilevered suspension, bending moments do not have to be absorbed on one side. Furthermore, unlocking the lace spool is easier, as will be explained below.
  • the quick-release device 9 can - regardless of a radial or tangential orientation of the rotation axis 11 - be attached, for example, to the tongue 6 of the shoe 1 in the region of an upper end of the lacing 4, although depending on the lacing 4, the quick-release device 9 can also be provided, for example, on an inside or outside of the shaft of the upper shoe 2.

  • Said housing 16 can surround or accommodate the two coils 10, 14, so that the two coils 10, 14 are closed or covered.
  • Said housing 16 can have inlet and outlet openings 17 on its circumference, through which the lace(s) 8, on the one hand, and the tensioning cable 13, on the other hand, can run in and out when they are wound onto or unwound from the respective coil.
  • the inlet/outlet opening 17 for the tensioning cable 13 is advantageously provided on an upper side of the housing 16, so that the tensioning cable 13 can be pulled out upwards, in particular approximately along the shinbone or the shaft of the upper shoe, in order to tighten the lacing 4.
