Definitions

  • the invention relates to a ski boot, in particular an alpine ski boot, comprising an outer shell having a lower shell part designed for connection to a ski binding and intended for receiving a foot, and an upper shaft part which is hingedly connected to the lower shell part and is intended for receiving a lower leg, wherein a distal and a medial end section of the upper shaft part are arranged at least partially overlapping in a use position and, in the use position, the distal end section is arranged inwardly and the medial end section is arranged outwardly, and the upper shaft part has an upper tensioning device which comprises a linear tension element and an actuating element for tensioning the linear tension element, wherein one actuating element is arranged on the distal end section of the upper shaft part, wherein the linear tension element has at least one free end which is connected to the actuating element in such a way that it is moved upon activation of the actuating element, so that the tension element can be transferred between a tensioned state and a non-tensioned state of the
  • Ski boots are specially designed boots for alpine, touring, telemark, and cross-country skiing. They are constructed to provide a stable connection between skier and ski.
  • the closure system of ski boots has evolved over the years.
  • Most modern ski boots use buckles to close the outer shell.
  • the outer shell usually contains an inner bootie, which provides comfort, support, and thermal insulation within the outer shell.
  • Conventional alpine ski boots typically have one or two buckles, usually two, on the upper shaft and one to three buckles, usually two, on the lower shell. Such buckles work with a lever mechanism, allowing the skier to tighten the shell of the ski boot tightly around the foot and lower leg.
  • the lever arm of the buckle is opened, the buckle is inserted into a notch, and then the lever arm is closed to achieve the desired tension.
  • the A wide Velcro fastener may be provided at the top of the ski boot. Properly closing the ski boot is important for good power transfer to the ski and for the skier's safety. A well-fitting ski boot not only provides better control over the skis but also minimizes the risk of injury.
  • Ski boots are also already known which have twist locks instead of conventional buckles, over which a linear tension element, i.e. a rope or wire-shaped tension element, can be tightened.
  • a linear tension element i.e. a rope or wire-shaped tension element
  • Ski boots which have a closing device for an upper shaft section or a cuff with a rope and a rotary fastener for tensioning and releasing the rope.
  • Two different designs are shown here, whereby in the first variant the rope is fixedly attached to the cuff at one end and the other end can be tensioned and released using the rotary mechanism. In the second variant, however, the rope for tensioning and releasing is attached at both ends to the rotary wheel.
  • it is sometimes necessary to open the cuff completely i.e. to move the end sections which overlap in the use position into a non-overlapping position, which is why a relatively long rope is required.
  • the first design variant also has the disadvantage that the rotary wheel must be turned many times to tension the long rope accordingly.
  • one embodiment features two holding elements to which two guide elements can be attached. If a user now wants to get in or out of the shoe, these guide elements must be removed or picked up from the holding elements. However, especially when closing the shoe, when they are picked up, the user needs both hands to prevent tangling.
  • a ski boot according to claim 1 it is particularly provided that, in a non-tensioned state, the tension element can be removed from the upper shaft part without tools, so that the upper shaft part can be transferred from a use position into an open position in which the end sections can be transferred into a non-overlapping open position.
  • a particularly advantageous guidance of the linear tension element can be achieved, in which the guide element, together with the tension element accommodated therein, can be removed from the distal end, wherein, however, a permanent connection between the distal end section of the shaft part and the tension element remains via the connection between the actuating element and the tension element even after the guide element has been removed from the distal end section of the shaft part, so that the risk of a tension element that has been completely detached from the distal end section becoming tangled is significantly reduced.
  • a linear tension element is understood to mean, in particular, rope- or wire-shaped tension elements that have an elongated, particularly cylindrical shape and are suitable for transmitting a tensile or tensioning force and are flexible, so that they can be guided via rollers, Deflection pulleys or winches can be guided.
  • the tension element is particularly preferably a lightweight wire rope, in particular made of stainless steel or another durable fiber, as is usually used in BOA® twist fasteners.
  • the guide element is an element that is stiffer than the tension element and defines the course of the tension element in the connection area between the guide element and the tension element.
  • the guide element has an at least preferably partially closed guide channel in which the tension element is slidably received.
  • the guide element can advantageously be made of plastic, such as polyamide 6, glass fiber reinforced polyamide 6, polyoxymethylene or the like.
  • the risk of the tension element becoming tangled in the open position of the upper shaft part can be further reduced if at least one deflection device is provided, which is arranged at the medial end section of the upper shaft part and is designed such that the tension element is connected to the upper shaft part both in the tensioned state of the tension element and in the non-tensioned state.
  • the tension element is attached to both the medial and distal end sections of the upper shaft part, thereby providing a local connection of the tension element to the upper shaft part at at least two points, namely the actuating element and the deflection device, and thus reliably preventing the tension element from becoming tangled.
  • the guide element is removed from the distal end of the upper shaft part, it is also ensured that the guide of the pulling element is so loose that the two end sections of the shaft can be transferred from an overlapping use position to a non-overlapping open position and thus a comfortable entry and exit into the ski boot is possible.
  • the linear pulling element has two free ends, and the two ends are connected to the actuating element in such a way that the two ends are moved upon activation of the actuating element, wherein preferably away from the two free ends of the linear pulling element extending sections of the linear tension element are guided around two different deflection devices which are arranged on the medial end section of the upper shaft part.
  • Design variants in which a tension element is provided, of which both free ends are connected to the actuating element have the advantage that when the actuating element, preferably a rotary wheel, is moved, and thus with one movement of the actuating element, in particular per revolution of the rotary wheel, twice the length of the tension element is tensioned compared to designs in which one end is fixedly attached to the upper shaft part.
  • the two sections of the tension element which extend away from the two ends connected to the actuating element can be guided directly and in particular without further deflection to different deflection devices on the medial end section, thereby achieving particularly efficient power transmission and low friction losses.
  • a particularly efficient and compact guide for the traction element can be achieved if the removable guide element is designed such that, in the use position, the traction element is guided circumferentially around the outside of the actuating element.
  • the guide around the actuating element a relatively large portion of the length of the traction element is guided around the actuating element when the guide element is attached. This leaves a relatively large portion of the traction element free when the guide element is removed, thus ensuring that the upper shaft section can be transferred between a use position and an open position for entry and exit.
  • a holding device is provided in the distal end section of the upper shaft part, by means of which the guide element is attached to the upper shaft part in the position of use.
  • a common fastening element is provided, via which the actuating device and the A holding device is attached to the upper shaft part, wherein the holding device is preferably arranged partially below the actuating device and has an opening for the passage of the common fastening element, in particular a screw or a rivet. Accordingly, both the actuating device and the holding device can be attached to the upper shaft part with a single fastening element.
  • the holding device comprises a holding element that is positively connected to the guide element in the use position, wherein a hook-shaped connecting element, in particular a snap hook, is preferably provided, which is received in a corresponding receptacle of the guide element in a functional position.
  • the positive connection can be formed, for example, by a projecting projection that prevents easy detachment of the guide element from the holding element by means of a sliding movement perpendicular to the plane of extension of the upper shaft part.
  • the guide element can be additionally secured in its arrangement on the holding element, so that removal of the guide element from the upper shaft part is only possible after the snap hook has been removed from a receptacle, preferably provided in the guide element, in particular a receiving groove.
  • the holding device can comprise a holding element that is magnetically connected to the guide element in the use position.
  • the guide element can be reliably connected to the holding device via a magnetic connection in the use position and can be easily removed from the holding device once the magnetic attraction force is overcome.
  • the guide element has a protruding handle.
  • the holding device has a curved contact surface, in particular a circular arc-shaped one
  • the guide element has a correspondingly curved support surface, in particular a circular arc-shaped one.
  • the curved support surface rests on the curved contact surface, preferably movable in the direction of the curved surfaces. If the guide element rests on the holding element in a movable, i.e., in particular rotatable, manner, the tension element accommodated in the guide element can automatically straighten itself during tensioning, depending on the tension force and volume of the user's leg.
  • the deflection device has at least one through-opening through which the traction element is guided in the use position.
  • the through-opening advantageously has a larger clear cross-section than the cross-section of the traction element, so that the traction element can be guided through the through-opening with relatively low friction losses.
  • the deflection device has a base element on which a deflection element, in particular with a circular arc-shaped deflection surface, is fastened, wherein the base element preferably has the at least one through-opening.
  • the base element is advantageously made of plastic, such as polyamide 6, glass fiber reinforced polyamide 6, polyoxymethylene or the like.
  • the deflection element is preferably made of wear-resistant plastic, such as polyamide 6, glass fiber reinforced polyamide, polyoxymethylene or the like.
  • the deflection element preferably has a groove in which the tension element is guided.
  • a roller in particular made of plastic or metal, can also be provided as the deflection element in order to reduce the friction between Tension element and deflection element to be reduced.
  • the deflection device or each deflection device advantageously has two through-openings, each having a longitudinal axis of extension.
  • the longitudinal axes of extension are preferably arranged in a V-shape relative to one another such that the tension element, when tensioned, is guided between the deflection device and the actuating element without kinks. Due to different leg volumes of different users and the individual tension of the tension elements, the exact course of the tension element is not always exactly the same. However, with the design according to the invention, the tension element can independently align itself in a straight pulling direction, thereby reducing friction losses and the associated wear.
  • the through-holes are advantageously arranged in different planes, i.e., material of the deflection device, in particular plastic, is provided between the intersecting sections of the tension element in the intersection area.
  • the actuating element has a rotary wheel, which can preferably be moved between an actuated position and an open position.
  • the ends of the linear tension element are driven when the rotary wheel is turned.
  • the rotary wheel preferably automatically moves to a locked position, so that the desired tension force introduced via the tension element is maintained.
  • the open position the rotary wheel is arranged to rotate freely, so that the tension of the The tension element can be quickly released.
  • This can in particular be a rotary dial of a BOA ® dial. It is known to use such closure systems in sports and leisure shoes.
  • the BOA ® system uses a linear tension element, in particular a (wire) cable.
  • a linear tension element in particular a (wire) cable.
  • a closure system with a rotary dial as can be used in the present invention, is known, for example, from EP 2 805 639 B2 described in detail.
  • One or both ends of the tension element are attached to the dial or knob. Turning this dial or knob winds or unwinds the tension element. Turning the knob clockwise tightens the tension element, making the boot fit tighter and more secure on the lower leg. This allows for very precise adjustment of the fit, which is faster and more consistent than with conventional buckles.
  • Many well-known dial fasteners also have an open or quick-release function.
  • a key advantage of a tensioning device with a dial is that the applied tension force can be adjusted quickly and easily, and the applied tension force can even be adjusted with one hand.
  • Another particular advantage is that during short breaks while skiing, for example, when riding a lift, in a hut, etc., to release the tension on the traction element, simply turn the dial to its open position. This is usually done by pulling out the knob. However, the traction element remains in a guided position, and by simply moving the lower leg forward slightly, the upper section of the shaft can be released to the point where the user no longer feels any pressure, without running the risk of the traction element becoming tangled.

  • the tension element 7 is pulled tighter, whereby the fit of the boot 1 on the lower leg becomes firmer and more secure.
  • the rotary fastener also has a well-known quick-release function.
