Description

[0001] 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 to receive a foot, and an upper shaft part which is hingedly connected to the lower shell part and is intended to receive 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 the 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 pulling element can be transferred between a tensioned state and a non-tensioned state of the pulling element, wherein a guide element for the linear pulling element is provided on the distal section of the upper shaft part.

[0002] 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 typically houses 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. These buckles work with a lever mechanism, allowing the skier to tighten the shell of the ski boot tightly around the foot and lower leg.To fasten, the buckle lever is opened, the buckle is inserted into a notch, and then the lever is closed to achieve the desired tension. A wide Velcro fastener can be added above the top buckle at the top of the ski boot if desired. Properly fastening 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.

[0003] 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.

[0004] In particular, WO 2020 / 160421 A1 shows ski boots which have a closing device for an upper shaft part or a cuff with a cable and a rotary closure for tensioning and releasing the cable. This shows two different design variants, wherein in a first variant the cable 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 cable for tensioning and releasing is attached at both ends to the rotary wheel. In order to be able to get in or out of the ski boot, 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 cable is required.When the ski boot is in the open position, there is a considerable risk of the rope becoming tangled due to the long rope length. In addition, three hands are required when closing or tightening the rope to prevent the rope from getting caught on various parts of the cuff. The first design variant also has the disadvantage that the dial must be turned many times to tension the long rope accordingly. To alleviate this disadvantage, one embodiment (see Fig. 17) features two holding elements to which two guide elements can be hooked. If a user now wants to get in or out of the boot, these guide elements must be removed from or picked up from the holding elements. However, the user again needs both hands, especially when closing the boot and picking them up, to prevent tangling.

[0005] It is therefore an object of the present invention to alleviate or eliminate one or more disadvantages of the prior art. In particular, the object of the invention is to provide a ski boot that allows for comfortable tightening and loosening of the tension element of the upper tensioning device, or comfortable closing and opening of the upper shaft section, with the user preferably requiring only one hand.

[0006] This object is achieved by a ski boot according to claim 1. According to the invention, 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.By arranging both a guide element that can be removed without tools and the actuating element at the distal end section of the shaft part, a particularly advantageous guidance of the linear pulling element can be achieved, in which the guide element together with the pulling element accommodated therein can be removed from the distal end, but via the connection between the actuating element and the pulling element, a permanent connection between the distal end section of the shaft part and the pulling element remains even after the guide element has been removed from the distal end section of the shaft part, so that the risk of a pulling element that has been completely detached from the distal end section becoming tangled is significantly reduced.In addition, when tightening the tensioning device to transfer the upper shaft part from an open position to a use position, the user can first easily position the guide element at the distal end section of the shaft part with one hand and then, by activating the actuating element, preferably with the same hand, transfer the tension element from a relaxed or non-tensioned state to a tensioned state. A linear tension element is understood to mean, in particular, rope- or wire-shaped tension elements that have an elongated, particularly cylindrical shape, and that are suitable for transmitting a tensile or tensioning force, and that are flexible so that they can be guided via rollers, pulleys, or winches.The tension element is particularly preferably a lightweight wire rope, in particular made of stainless steel or another durable fiber, such as those commonly used in BOA®< twist fasteners. The guide element is provided as an element that is stiffer than the tension element and defines the path of the tension element in the connection area between the guide element and the tension element. In particular, 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.

[0007] 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. Thus, even in the open position, 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.If 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.

[0008] Furthermore, it is advantageous if the linear tension 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 sections of the linear tension element extending away from the two free ends of the linear tension element are preferably guided around two different deflection devices arranged on the medial end section of the upper shaft part. Design variants in which a tension element is provided, both free ends of which are connected to the actuating element, have the advantage that upon movement of the actuating element, preferably a rotary wheel, both ends are 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.In addition, the two sections of the pulling 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 at the medial end section, thereby achieving particularly efficient power transmission and low friction losses.

[0009] 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. By means of 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.

[0010] For a simple and reliable fastening of the guide element to the upper shaft part, it is advantageous if a holding device is provided in the distal end section of the upper shaft part, by means of which the guide element is fastened to the upper shaft part in the position of use.

[0011] For a compact, simple, and material-saving design, it is advantageous to provide a common fastening element by means of which the actuating device and the holding device are attached to the upper shaft part. Preferably, the holding device is arranged partially beneath the actuating device and has an opening for the passage of the common fastening element, in particular a screw or rivet. Accordingly, both the actuating device and the holding device can be attached to the upper shaft part with a single fastening element.

[0012] To ensure that the guide element does not accidentally detach from the holding device, it is advantageous if the holding device comprises a holding element that is positively connected to the guide element in the use position. Preferably, a hook-shaped connecting element, in particular a snap hook, is 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, which prevents simple 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.With the aid of the snap hook, 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, in particular a receptacle groove, preferably provided in the guide element.

[0013] Alternatively, in addition to a positive and optionally locking connection, the holding device can comprise a holding element that is magnetically connected to the guide element in the use position. Thus, 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.

[0014] For particularly user-friendly handling, it is advantageous if the guide element has a protruding handle.

[0015] For a compact design in which the guide and holding elements are connected to one another over comparatively large surfaces, it is advantageous if the holding device has a curved contact surface, in particular in the shape of a circular arc, and the guide element has a correspondingly curved support surface, in particular in the shape of a circular arc, wherein in the position of use 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 tensioning force and volume of the user's leg.

[0016] To ensure that the traction element is not completely detached from the upper shaft section in the open position, but rather held at the medial end section, thus avoiding unwanted tangling, which is useful for high ease of use, it is advantageous if 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.

[0017] For cost-effective and efficient production of the deflection device, it is advantageous if 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 the tension element and the deflection element.

[0018] 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 so that the tension element, when tensioned, is guided between the deflection device and the actuating element without kinks. Due to the 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.

[0019] As an alternative to a V-shaped arrangement of the two through-openings of a deflection device, it has proven particularly effective for a low-friction path of the tension element to provide two through-openings that are arranged in different planes in plan view and intersect each other. The intersecting arrangement allows the tension element to align even more rectilinearly during tensioning. To avoid friction losses at the intersection point, the through-openings 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.

[0020] For simple, reliable, and comfortable tensioning or releasing of the tension element, it is advantageous if the actuating element has a rotary dial that can preferably be moved between an actuated position and an open position. In the actuated position, the ends of the linear tension element are driven when the rotary dial is turned. As long as no more torque is exerted on the rotary dial by the user, the rotary dial preferably automatically moves to a locked position so that the desired tensioning force introduced via the tension element is maintained. In the open position, the rotary dial is arranged to rotate freely so that the tension of the tension element can be released quickly. This can in particular be a rotary dial of a BOA ®< rotary fastener. The use of such closure systems in sports and leisure shoes is known.Instead of traditional laces, the BOA® system uses a linear tension element, in particular a (wire) cable. Such a closure system with a dial, as can be used in the present invention, is described in detail in EP 2 805 639 B2, for example. 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 results in a very precise fit adjustment that is faster and more consistent than with conventional buckles. Many well-known dial closures also have an open or quick-release function. This is usually done by pulling out the dial, which immediately releases the tension element and allows the ski boot to be removed quickly and easily.A key advantage of a tensioning device such as this, which includes a rotary dial, is that the applied tension can be adjusted quickly and easily. The applied tension can even be adjusted with a single hand. A particular advantage is that during short breaks while skiing, e.g. when riding on the lift, in a hut, etc., to release the tension on the tensioning element you only need to turn the rotary dial to its open position, which is usually done by pulling out the knob. The tensioning element, however, remains in a guided position and just by moving the lower leg slightly forwards you can relax the upper section of the shaft to the point where the user no longer feels any pressure, without running the risk of the tensioning element getting tangled up somewhere.

[0021] In order to tighten the lower shell part and thus be able to adapt it tightly to the foot accommodated therein, it is advantageous to provide at least one buckle for tightening the lower shell part. However, an alternative tightening device, e.g., with a preferably rotatable actuating element and a linear tension element, can also be provided on the lower shell part.

[0022] The invention will be explained in more detail below using preferred embodiments, to which it is by no means limited. The drawings show: Fig. 1 an oblique view from above of a front side of a ski boot according to the invention with an upper shaft part which has a tensioning device with a linear tension element; Fig. 2 an oblique view from behind of the ski boot according to the invention according to Fig. 1 ; Fig. 3 an oblique view of the ski boot according to the invention according to Fig. 1 with a guide element for the linear pulling element removed from the upper shaft part; Fig. 4 in an oblique view, an exploded view of the ski boot according to the invention in the area of ​​the attachment of a holding device and the guide element on the upper shaft part; Fig. 5 an oblique view according to Fig. 4 with the ski boot according to the invention in the assembled state; Fig. 6 in oblique view an exploded view of a holding element of the holding device; Fig. 7 an oblique view of the guide element in a position connected to the holding element; Fig. 7a an exploded view of the actuating element in bottom view; Fig. 7b an exploded view of the actuating element in top view Fig. 8 a sectional view of a holding device with a magnet; Fig. 8a an exploded view of the holding device with a magnet according to Fig. 8 ; Fig. 9 und 10 Oblique views of the upper shaft part of the ski boot according to the invention with a rotatably mounted guide element; Fig. 11 an oblique view of the upper shaft part of the ski boot according to the invention with two deflection devices; Fig. 11a a plan view of a base element of a deflection device; Fig. 11b an oblique view of the base element according to Fig. 11a ; Fig. 12 an oblique view of a ski boot according to the invention with an alternative guide of the pulling element; Fig. 13 a plan view of a base element of a deflection device according to the embodiment according to Fig 12 ; Fig. 14 a cross-section of a base element of a deflection device according to the embodiment according to Fig 12 ;

[0023] In Fig. 1 An alpine ski boot 1 according to the invention is shown, which has an outer shell 1a with a lower shell part 2, which is designed for connection to a ski binding and is provided for receiving a foot. An upper shaft part 3 is connected to the lower shell part 2 via a joint 4. The upper shaft part 3 is provided for receiving a lower leg of a user and has a distal and a medial end section 3a, 3b, which in the Fig. 1 shown are arranged partially overlapping in the use position shown. In the overlapping use position shown, the distal end section 3a is arranged inward and the medial end section 3b is arranged outward, ie, the medial end section 3b partially rests on the distal end section 3a. A padded inner shoe 1b, which is relatively soft compared to the lower shell and upper shaft parts 2, 3, is accommodated in the outer shell 1a, ie, in the lower shell part 2 and the upper shaft part 3.

[0024] In order to be able to clamp a lower leg accommodated in the upper shaft part 3, an upper clamping device 5 is provided, which has a rotary wheel 6a as the actuating element 6. With the actuating element 6, a linear tension element 7 can be transferred between a tensioned and a non-tensioned, i.e., relaxed, state. When the rotary wheel 6a (often also called a rotary knob) is rotated, the tension element 7 is wound up or unwound; the rotary movement of the rotary knob is preferably implemented via a planetary gear 6b ​​(cf. Fig 7b By turning the rotary knob 6a clockwise, the tension element 7 is pulled tighter, whereby the fit of the boot 1 on the lower leg becomes firmer and more secure. This results in a very precise adjustment of the fit, which is faster and more even than with conventional buckles. The rotary fastener also has a well-known quick-release function. For this purpose, the rotary knob 6a is pulled out of its rotary socket, whereby the tension element 7 is immediately released and the ski boot can be removed quickly and easily. A significant advantage of a tensioning device 5 of this type comprising a rotary wheel 6a is that the applied tension force can be adjusted quickly and easily, whereby the applied tension force can even be adjusted with a single hand. Another particular advantage is that during short breaks while skiing, e.g. when riding the lift, in the hut, etc.To release the tension on the pulling element, the rotary wheel only needs to be moved into its open position using the quick-release function, which is done by pulling out the button. The pulling element 7, however, remains in a guided position and only by slightly moving the lower leg forwards can the upper shaft part 3 be released to such an extent that the user no longer feels any pressure, without running the risk of the pulling element getting caught somewhere. Rotary fasteners of this type comprising a rotary wheel are generally known and are used in particular in sports and leisure shoes. A fastening system of this type with a rotary wheel 6a, as can be used in the present invention, is described in detail, for example, in EP 2 805 639 B2.

[0025] In the Fig. 1 In the embodiment shown, both ends 7a, 7b of the tension element 7 are fastened to the rotary knob 6a via a connecting piece 6c, which is connected to the rotary knob 6a by means of a planetary gear 6b ​​(cf. Fig. 7a, Fig. 7b ); the end sections 7', 7" adjoining the two different ends are in Fig. 1 visible. When the rotary wheel or knob 6a is turned, both ends or both end sections 7', 7" are wound or unwound, so that even with a comparatively small rotation of the rotary wheel 6a, a noticeable adjustment of the tensioning force introduced via the tensioning device 5 is achieved.

[0026] How further in Fig. 1 As can be seen, two buckles 8 are assigned to the lower shell part 2 in a conventional manner in order to tighten the lower shell part 2 and thus be able to adapt it tightly to a foot accommodated therein. However, an alternative tightening device, e.g., with a preferably rotatable actuating element 6 and a linear tension element 7, as in the upper shaft part 3, can also be provided on the lower shell part 2.

[0027] As can be seen particularly from a summary of the Fig. 1 and 2The pulling element 7 has the following course: Starting from the two ends of the pulling element 7 fastened to the rotary wheel 6a, the adjoining end sections 7', 7" run from the distal end section 3a, on which the actuating device 6 is arranged, essentially in a straight line to the medial end section 3b of the upper shaft part 3. Two deflection devices 9 are fastened to the medial end section 3b, which are designed in such a way that the pulling element 7 can be guided in the tensioned state of the pulling element as well as in the non-tensioned state (cf. Fig 3 ) is connected to the upper shaft part 3. Thus, even in an open position, the tension element 7 is fastened to both the medial and distal end sections 3a, 3b of the upper shaft part 3, thereby providing a local connection of the tension element 7 on the upper shaft part 3, to the actuating element 6, and to the deflection devices 9. Tangling of the tension element 7, even in an open position of the upper shaft part 3, can thus be reliably prevented.

[0028] In the Fig. 11, 11a und 11b or Fig. 12 bis 14 Two alternative embodiments of the deflection device 9 are shown. In a first embodiment, a base element 10 is provided which has two through openings 11. As in Fig. 11a und 11b As can be seen, the tension element 7 in both deflection devices 9 is guided through circumferentially closed through-openings 11, so that even in the non-tensioned state of the tension element 7 and in particular in the open position of the upper shaft part 3, the tension element 7 remains connected to the medial end section 3b of the upper shaft part 3. The through-openings 11 have a larger clear cross-section than the cross-section of the tension element 7, whereby the tension element 7 can be guided through the through-openings 11 with relatively low friction losses.

[0029] As further particularly in Fig. 11 As can be seen, a deflection element 12 is arranged on the base element 10, each of which has a circular arc-shaped deflection surface. The base element 10 and the deflection element 12 are fastened to the upper shaft part 3 via a common fastening element 13, in particular a screw. Both the base element 10 and the deflection element 12 are preferably made of plastic, such as polyamide 6, glass fiber reinforced polyamide 6, polyoxymethylene or the like. As shown in Fig. 11 As can be seen, the deflecting element 12 has a groove 12a in which the tension element 7 is guided. Alternatively, a roller, particularly made of plastic or metal, can be provided as the deflecting element 12 in order to reduce the friction between the tension element 7 and the deflecting element 12.

[0030] As particularly in Fig. 11a in conjunction with Fig. 1 As can be seen, the two through-openings 11 of a base element 10 each have longitudinal extension axes 11a that are arranged in a V-shape relative to one another such that the tension element 7, when tensioned, is guided between the deflection device 9 and the actuating element 6 without kinks. Due to the different leg volumes of different users and the individual tension of the tension element 7, the exact course of the tension element 7 is not always exactly the same. However, with the V-shaped arrangement of the through-openings 11 relative to one another, the tension element 7 can independently arrange itself in a straight tension direction, whereby friction losses and the associated wear can be reduced.

[0031] As an alternative to a V-shaped arrangement of the two through openings 11, as shown in Fig. 12 bis 14 As can be seen, two through openings 11 are provided in the base element 10, which are arranged in different planes in plan view (cf. Fig. 14 ) and cross each other (cf. Fig. 13 ). The crossing arrangement allows the tension element 7 to align itself even more straightly during tensioning (cf. Fig. 12 ).

[0032] As again in Fig. 1 and 2 As can be seen, the pulling element 7, after being deflected via the deflection devices 9 at the medial end section 3b, is returned to the distal end section 3a, on which the actuating element 6 is fastened, and is deflected here via a guide element 14, so that - starting from the two ends arranged on the actuating element 6 - a closed course of the pulling element 7 results.

[0033] As particularly in Fig. 3 As can be seen, the guide element 14 can be arranged in the position of use on the upper shaft part 3 (cf. Fig. 1 and 2 ) from the distal end section 3a of the upper shaft part 3. As a result, the pulling element 7 remains connected to both end sections 3a, 3b via the actuating element 6 and the deflection devices 9, but at the same time it is ensured that the guidance of the pulling element 7 is so loose that the two end sections 3a, 3b of the upper shaft part 3 can be transferred from an overlapping use position into a non-overlapping open position, thus enabling comfortable entry and exit into the ski boot 1.

[0034] To transfer the upper shaft part 3 from an open position ( Fig. 3 ) into a use position ( Fig. 1 and 2), the guide element 14 is first positioned at the distal end portion of the upper shaft part. Subsequently, the tension element 7 is tensioned by rotating the rotary wheel 6a, and thus the tension element can be transferred from a relaxed or non-tensioned state to a tensioned state using the same hand with which the guide element was previously attached to the upper shaft part 3.

[0035] Due to the guidance of the pulling element 7 with the aid of the guide element 14 around the actuating element 6, a holding element 15a of the holding device 15, which is intended to hold the guide element 14 on the upper shaft part 3 in a use position, can be fastened together with the clamping device 5 on the upper shaft part 3. As shown in particular in Fig. 4 As can be seen, the holding element 15a is arranged partially below the actuating device 6. The upper shaft part 3 has a protrusion 16, which is received in a corresponding recess 16' when the holding element 15a is mounted. Due to the angular cross-sectional shape of the protrusion 16 and the recess 16', the holding element 15a is positively secured against rotation. The holding device 15 or the holding element 15a and the actuating device 6 are fastened to the upper shaft part 3 via fastening elements 17, in particular screws, whereby only one of the three screws is required for the holding element 15a.

[0036] As particularly in Fig. 4 As can be seen, the holding element 15a is preferably designed in a substantially Z-shaped manner in a side view, ie a curved contact surface 15'' is provided projecting from a fastening surface 15', to which a stop surface 15' in turn adjoins at an angle. The guide element 14 has a contact surface 14' curved in accordance with the contact surface 15'', wherein in the position of use the curved contact surface 14' rests on the curved contact surface 15''. As shown in the Fig. 9 und 10 As can be seen, the guide element 14 remains movable in its functional position arranged on the holding element 15a, ie a sliding movement between the support surface 14' and the contact surface 15'' is possible, so that the guide element 14 can perform a rotating movement about a center of curvature of the curved contact surface 15'' (cf. Figuren 9 und 10 ). Thus, the tension element accommodated in the guide element 14 can automatically align itself straight during tensioning, depending on the tensioning force and volume of the user's leg. The stop surface 15‴ holds the guide element in a form-fitting manner in the direction perpendicular to the plane of extension of the upper shaft part 3, so that in order to remove the guide element 14 from the holding element 15a, the guide element 14 must be removed from the holding element 15a against the pulling direction of the tension element 7, so that the support and contact surfaces 14', 15" are no longer in contact before the guide element 14 can be removed from the holding element 15a.

[0037] In the Fig. 5 and 7the guide element 14 is shown in a position fastened to the upper shaft part 3 via the holding device 15. In particular, it can also be seen that the holding device 15 has a hook-shaped connecting element 18 to secure the guide element 14 to the holding element 15a. In its functional position, the connecting element 18 is received in a corresponding receiving groove 19 in the guide element 14, so that the guide element 14 is secured to the holding element 15a in its functional position, but a sliding movement between the support surface 14' and the contact surface 15'' is still possible, so that the guide element 14 can perform a rotating movement in the direction of arrow 14'' around a center of curvature of the curved contact surface 15'' (cf. Figuren 9 und 10 ). The holding element 15a together with the hook-shaped connecting element 18 is usually made of a plastic material, so that the hook-shaped connecting element 18, after being pivoted out of its rest position, strives to return to the rest position. Thus, the hook-shaped connecting element 18 is designed as a snap hook. To increase the spring force of the snap hook, as shown in Fig. 6 und 7 visible - a spring element 18a, which is made of metal, for example, can be snapped onto the hook-shaped connecting element 18.

[0038] As an alternative to a positive and optionally locking connection between the holding element 15a and the guide element 14, the holding device 15 can comprise a magnetic holding element 15b, which is magnetically connected to a mutually polarized magnet 14b in the guide element 14 in the use position. The magnetic holding element 15b is preferably attached to the upper shaft part 3 via a rivet 15c. Thus, the guide element 14 can be reliably connected to the holding device 15 in the use position via a magnetic connection and can be easily removed from the holding device when the magnetic attraction force is overcome.

[0039] A particularly user-friendly handling of the guide element 14 is achieved if the guide element 14 has a protruding grip part 20. The grip part 20 can be formed, for example, by a tab that is connected to the guide element 14 in an articulated or flexible manner.
