Description

[0001] The present invention relates to a ski binding adapter designed for at least temporarily connecting an alpine ski boot to an alpine ski binding mounted on a ski.

[0002] It is known that various types of binding systems are used, such as alpine ski bindings for alpine skis, also known as downhill skis. These bindings are combined with alpine ski boots, also known as alpine ski boots, to enable downhill skiing, i.e., a controlled descent of a mountain slope. In this system, the alpine ski boot is fixed to the ski at both the front and back and cannot pivot relative to the ski. Also known are touring bindings, which are mounted on the ski and designed to allow for ascending on skis in mountainous terrain without the use of ski lifts. In this system, the alpine ski boot is essentially fixed to the ski at the front and can be lifted off the ski at the rear, allowing for a nearly natural movement when climbing a mountain slope.

[0003] In addition to these "classic" alpine and touring ski bindings, so-called hybrid bindings are known, in which a binding toe piece and a binding heel piece are fixed to the ski. In touring mode, such hybrid bindings allow a pivoting movement of the ski boot when climbing uphill. Before the descent, the binding is then switched to a downhill mode by fixing the ski boot to the binding heel piece, so that the boot can no longer pivot. Furthermore, adapters are known that are inserted into an existing alpine ski binding and are intended to allow movement of the rear part of the user's alpine ski boot.

[0004] A disadvantage of the current state of the art is that, for example, hybrid bindings represent only a compromise between the two binding systems and are not offered at a low price, as they usually require complex mechanics. With adapters, a particular problem arises because they are not adapted to an existing alpine ski binding already mounted on a ski and adjusted to the user's alpine ski boot, resulting in undesirable tolerances. Such tolerances negatively impact user safety. Since these adapters are typically length-adjustable in predetermined increments, they are mechanically complex and manufactured from multiple parts, which negatively affects their stability, robustness, flexural rigidity, and torsional stiffness along their longitudinal axis.Furthermore, such adapters are only offered in limited sizes and are therefore not available for use in the adult sector.

[0005] Against this background, an object of the invention is to provide a ski binding adapter that is particularly precise in its fit, robust and safe, and that can be manufactured inexpensively. Furthermore, the ski binding adapter should exhibit high stiffness values ​​at a low weight.

[0006] According to the invention, a ski binding adapter is provided for at least temporarily connecting an alpine ski boot to an alpine ski binding mounted on a ski.

[0007] The ski binding adapter includes: a longitudinally extended, one-piece clamping part, its length adapted to the sole length of the alpine ski boot and / or the binding width of the alpine ski binding, comprising a middle section, a front end section and a rear end section, as well as {a} a base plate and at least one pivotable fastening element arranged on the base plate, wherein the base plate is designed such that the alpine ski boot can be at least temporarily arranged and fastened on it, wherein the base plate is pivotably connected to the clamping part about a transverse axis of the clamping part, the transverse axis passing through the front end part of the clamping part, and wherein the fastening element is designed to at least temporarily fix the alpine ski boot on a top side of the pivotable base plate; and / or {b} a pin adapter arranged on the front end part (e.g. detachable or permanent) which is designed such that a pin insert of the alpine ski boot can be connected to the pin adapter at least temporarily for pivotable attachment of the alpine ski boot to the ski binding adapter.

[0008] The ski binding adapter according to the invention is designed to be inserted and locked, at least temporarily, into an alpine ski binding already mounted on a ski, in order to connect a user's alpine ski boot to the ski in a pivotable manner, at least temporarily. The insertion and locking of the clamping part of the ski binding adapter is analogous to the insertion and locking of an alpine ski boot sole into the alpine ski binding.

[0009] For example, when skiing downhill, the user's alpine ski boot is inserted into the alpine ski binding mounted on the ski, locked in place, and thus not pivotable. With the ski binding adapter according to the invention, the user's alpine ski boot is indirectly pivotably fixed in the alpine ski binding. "Indirectly" in this case means that the ski binding adapter according to the invention is arranged between the user's alpine ski boot and the ski, providing a pivotable and force-transmitting connection between the alpine ski boot and the ski. The pivotable and force-transmitting connection of the alpine ski boot provided by the ski binding adapter enables the user to ascend the mountain, for example, when no aid such as a ski lift can be used or when higher mountain regions above the ski lifts are to be accessed using the ski binding adapter.

[0010] A pivotable connection or fixation of this kind means that the user's alpine ski boot is pivotally fixed at the front of the boot on a pivot axis, also referred to here as the transverse axis, such that the rear of the boot, including the user's heel, can be raised and lowered within a predetermined range, while the front of the boot remains essentially stationary on the ski binding adapter. During this pivoting of the ski boot, the longitudinal axis of the user's ski boot is aligned with the longitudinal axis of the ski. This predetermined range can encompass a pivot angle of the ski boot relative to the horizontal of approximately 0 degrees to approximately 90 degrees.This swivel angle of the alpine boot is important for both the first and second versions of the ski binding adapter, which are explained in more detail below, to ensure a largely natural walking motion in mountainous terrain. Furthermore, this swivel angle of up to approximately 90 degrees is necessary for the so-called kick turn performed by ski tourers when ascending steep terrain, where one ski must be lifted and rotated while lifted.

[0011] The force generated by the user's foot movements is transferred to the ski via the pivoting connection or fixation of the user's alpine ski boot to the ski, essentially through the front part of the alpine ski boot and the front end of the ski binding adapter. A single transverse axis, or pivot axis, is used, designed to ensure optimal force transmission from the ski boot to the clamping part and thus to the alpine ski. This applies at least temporarily during ascents in off-piste terrain. This single transverse axis serves to simplify and thus robustly design the ski binding adapter, as well as to optimize weight. The position of this single transverse axis could also be chosen so that it is positioned approximately vertically below the ball of the user's foot, allowing for a largely natural rolling motion of the foot and leg.

[0012] In a first embodiment of the ski binding adapter, it comprises a longitudinally extended, one-piece clamping element, the length of which is adapted to the sole length of the alpine ski boot and / or the binding width of the alpine ski binding, having a middle section, a front end section and a rear end section, as well as a base plate and at least one pivotable fastening element arranged on the base plate, wherein the base plate is designed such that the alpine ski boot can be at least temporarily arranged and fastened on it, wherein the base plate is pivotably connected to the clamping element about a transverse axis of the clamping element, the transverse axis passing through the front end section of the clamping element, and wherein the fastening element is designed to at least temporarily fix the alpine ski boot on a top surface of the pivotable base plate.

[0013] In a second embodiment of the ski binding adapter, it comprises a longitudinally extended, one-piece clamping part, its length adapted to the sole length of the alpine ski boot and / or the binding width of the alpine ski binding, having a middle part, a front end part and a rear end part, as well as a pin adapter arranged on the front end part, which is designed in such a way that a pin insert of the alpine ski boot can be connected to the pin adapter at least temporarily for pivotable attachment of the alpine ski boot to the ski binding adapter.

[0014] Both versions can be achieved using an identical, one-piece clamping unit. This increases flexibility for the user while simultaneously reducing costs. It is conceivable that the ski binding adapter could be converted between the first and second versions by the user. For example, in the first version, the base plate could be detachably attached to the clamping unit, and / or the pin adapter could be detachably attached to the clamping unit in the second version. It is also conceivable that the pin adapter is permanently attached to the clamping unit, but the base plate can be detached. Alternatively, both the pin adapter and the base plate could be permanently attached to the clamping unit.It is conceivable that the base plate could be locked in place by the user relative to the clamping part, particularly if the user's ski boot is or is to be connected to the pin adapter. Other ways of converting the ski binding adapter between the first and second versions are also conceivable.

[0015] In both versions of the ski binding adapter, the clamping element is longitudinally oriented, meaning that its length is significantly greater than its width. For example, depending on the length of a user's foot, the length of the clamping element ranges from 15 cm to 40 cm, while the maximum width ranges from 6 cm to 8 cm. Due to the manufacturing processes for the clamping element according to the invention, virtually any length is possible and can be industrially produced, particularly for alpine ski boot sizes for children, teenagers, and adults of all ages and genders.

[0016] Typically, an alpine ski binding mounted on a ski is arranged or adjusted in such a way that it is optimally adapted to the sole length of the user's alpine ski boot to be placed in the alpine ski binding.

[0017] The essential feature of both embodiments of the ski binding adapter is that the length of the clamping part of the ski binding adapter is adapted to the sole length of the alpine ski boot and / or the binding width of the alpine ski binding to be used. In other words, the length of the clamping part of the ski binding adapter corresponds to the sole length of the user's alpine ski boot, which is easily determined by measuring the length. The binding width of the alpine ski binding is understood to be the clear inside dimension between the front and rear parts of the alpine ski binding, which is fixed to the ski and ideally corresponds to the sole length of the user's alpine ski boot and, according to the invention, to the length of the clamping part of the ski binding adapter.When the sole length or the length of the clamping part corresponds to the binding width of the alpine ski binding, tolerances occur, which are typically in the range of 2 mm or less, and especially in the range of 1 mm or less. Ideally, the length of the clamping part of the ski binding adapter is ≤ 0.5 mm shorter than the sole length of the alpine ski boot and / or the binding width of the alpine ski binding. In other words, the clamping part can be custom-made with a maximum deviation of less than 2 mm, especially less than 1 mm, and ideally less than 0.5 mm, from the sole length of the alpine ski boot of the individual skier. The clamping part, and thus the ski binding adapter, can therefore be used by the alpine skier for any alpine ski equipped with an alpine ski binding and adjusted to the alpine ski boot with its corresponding sole length.This creates greater variability and choice for alpine skiers and ski tourers, as neither a dedicated touring binding nor special touring skis are required for ascending the mountain. Any existing alpine ski can therefore be converted for ski touring or ascending, for example, using a ski binding adapter and climbing skins attached to the base of the alpine skis for climbing.

[0018] This precision, or rather the low tolerance occurring during the manufacturing of the clamping element with respect to the sole length of the alpine ski boot and / or the binding width of the alpine ski binding, increases user safety. The reason for this improved safety lies in the fact that the alpine ski binding attached to the ski is set to the exact sole length of the user's alpine ski boot and other user parameters, while the clamping element according to the invention precisely replicates the sole length of the alpine ski boot. Thus, in an emergency situation where the alpine ski binding is supposed to release, there is no significant difference between an alpine ski boot fixed directly in the alpine ski binding and the use of the ski binding adapter according to the invention in the alpine ski binding.

[0019] A further essential aspect of the invention is that the clamping element is manufactured in one piece. This one-piece design enables robust and dimensionally accurate manufacturing. The clamping element thus exhibits a predetermined flexural strength and a predetermined torsional stiffness, also known as twisting stiffness, for use in an alpine ski binding. Since the clamping element is manufactured in one piece and precisely to the required sole length of the user's alpine ski boot, a sometimes complex length adjustment mechanism, which can lead to instability, is unnecessary. This match between the length of the clamping element and the sole length of the alpine ski boot and / or the binding width of the alpine ski binding, combined with the robust, torsionally stiff, and one-piece design of the clamping element, ensures optimal power transmission from the user to the ski via the ski binding adapter.Furthermore, the user's perception of the ski's position and tilt, its grip, and the edge's traction in the snow—also known as ski feedback—is enhanced. Additionally, improved user safety is achieved, particularly in critical situations, as it prevents premature releases of the alpine ski bindings.

[0020] According to the present invention, the clamping element comprises a middle section, a front end section, and a rear end section. The three-section design of the clamping element allows for optimal adaptation of the clamping element for use in the alpine ski binding mounted on a ski. This ensures that the front and rear end sections are adapted to the inner contours of the front and rear sections of the alpine ski binding, respectively, while the middle section is robust, torsionally rigid, and yet material-efficient.

[0021] In the first embodiment of the ski binding adapter according to the invention, a pivotable fastening element is arranged on the base plate, the base plate being designed and configured such that the alpine ski boot can be at least temporarily positioned and secured on it. Thus, the alpine ski boot is securely held on the base plate and pivotably attached to the ski binding adapter using the fastening element, allowing the user to pivot with the alpine ski boot and thus enabling ascent in mountainous terrain without a ski lift. The pivotable fastening element is designed to position the alpine ski boot at least temporarily on the base plate and provides a detachable connection between the base plate and the alpine ski boot.

[0022] Another advantage is that the ski binding adapter can be quickly detached from the alpine ski binding. This detachment is achieved, for example, after completing the ascent on the mountain, by simply operating or opening the rear part of the alpine ski binding.

[0023] The base plate is pivotably connected to the clamping part about a transverse axis of the clamping part, with the transverse axis running through the front end section of the clamping part. Thus, the base plate and the alpine ski boot attached to the base plate are essentially fixed above the ski and at a defined distance from the ski in the front section of the ski binding adapter, where the front end section of the clamping part is inserted into the front part of the alpine ski binding. The distance of the base plate, and therefore the distance of the alpine ski boot, can be changed in the rear section of the ski binding adapter, where the rear end section of the clamping part is inserted into the rear part of the alpine ski binding, by pivoting the base plate with the alpine ski boot. This pivoting action raises or lowers the rear part of the alpine ski boot.

[0024] In the second embodiment of the ski binding adapter according to the invention, a pin adapter is arranged on the front end piece. This pin adapter is designed such that a pin insert of the alpine ski boot can be at least temporarily connected to the pin adapter for pivotable attachment of the alpine ski boot to the ski binding adapter. In this way, the distance of the alpine ski boot in the rear area of ​​the ski binding adapter, in which the rear end piece of the clamping part is inserted into a rear part of the alpine ski binding, can be changed, thus enabling the user to ascend in mountainous terrain without a ski lift.

[0025] The ski binding adapter can be designed such that the middle section is narrowed, while the front end section and / or the rear end section is widened and optionally rounded.

[0026] The fact that the middle section of the adapted one-piece clamping element is narrowed means that its width, measured horizontally and perpendicular to a longitudinal axis of the clamping element, is less than the width of the front end section and / or less than the width of the rear end section. The basic shape of the clamping element, viewed from above when installed in the alpine ski binding, is, for example, dumbbell-shaped or bone-shaped, with the clamping element positioned in the ski in a typical operating position, for example, essentially horizontal to a flat surface. The middle section, in particular, forms a connection between the front and rear end sections of the one-piece clamping element. A narrower or tapered middle section contributes to a reduction in the weight of the ski binding adapter.

[0027] The central section can be cuboid, hollow cuboid, or a 3D structure with cutouts. It can have an outer wall or be an outwardly open profile without an outer wall, such as an outwardly open 3D lattice structure with internal cavities. The central section can be designed to provide the required bending strength and torsional stiffness. In one example, the width of the central section ranges from 20 mm to 50 mm, while the widths of the front and rear end pieces range from 50 mm to 80 mm.

[0028] In one variant, the central section consists of one or more parallel cylindrical struts arranged between the front and rear end sections within the one-piece clamping element. In this variant, the central section can also be configured with straight or curved struts with open spaces between them. These variants ensure both the required bending strength and torsional stiffness while saving material and weight. In another variant, the central section is a hollow cuboid, with an opening preferably oriented downwards towards the ski.

[0029] The ski binding adapter can be designed such that the front end piece is formed in its outer contour, shape and / or geometry corresponding to an inner contour, shape and / or geometry of a front part of the alpine ski binding, and that the rear end piece is formed in its outer contour, shape and / or geometry corresponding to an inner contour, shape and / or geometry of a rear part of the alpine ski binding.

[0030] By designing the front end piece with an outer contour, shape, and / or geometry corresponding to an inner contour, shape, and / or geometry of the front part of the alpine ski binding, optimal alignment of the front end piece with the inner contour of the front part of the alpine ski binding is ensured when the mounting piece is positioned in the alpine ski binding. Furthermore, by designing the rear end piece with an outer contour, shape, and / or geometry corresponding to an inner contour, shape, and / or geometry of the rear part of the alpine ski binding, optimal alignment of the rear end piece with the inner contour of the rear part of the alpine ski binding is ensured when the mounting piece is positioned in the alpine ski binding.

[0031] Here, the terms "outer contour" and "inner contour" refer to an outer silhouette viewed from above or from the side of the front or rear end piece, or an inner silhouette viewed from above or from the side of the front or rear part of the alpine ski binding, respectively. It is understood to those skilled in the art that a view of the inner silhouette of the front and rear parts of the alpine ski binding is only possible to a limited extent through the binding's housing components. For example, the outer contour of the front and / or rear end piece may be trapezoidal or semicircular.

[0032] Furthermore, the term "shape" refers to a three-dimensional external design of the front or rear binding section, or a three-dimensional internal design of the front or rear binding section of the alpine ski binding. For example, the front and / or rear binding section may be designed as a trapezoidal prism or a half-cylinder. In the case of a three-dimensional design of the front binding section as a trapezoidal prism, the internal design of the front binding section is correspondingly designed and can optimally enclose the trapezoidal prism-shaped front binding section, thus fitting it snugly with minimal tolerance.

[0033] The term "geometry" also encompasses measurable parameters such as length, width, and height of the three-dimensional design, for example, of the front or rear binding. Measurable parameters also include the angles of corners or edges, such as in a trapezoidal prism design of the binding. Similarly, measurable parameters include the radii of curves on the front or rear binding. These measurable external parameters of the front and / or rear binding correspond to measurable internal parameters of the toe and / or heel of the alpine ski binding. Furthermore, these parameters also correspond to the sole geometry and sole height of an alpine ski boot.

[0034] It may be possible, for example, to scan the user's alpine ski boot, particularly the sole, using a 3D scan. This allows the outer contour, shape, and / or geometry of the sole to be determined. This scan can then form the basis for manufacturing the binding component, with the front end piece being manufactured to match the outer contour, shape, and / or geometry of the front part of the ski boot sole, and the rear end piece being manufactured to match the outer contour, shape, and / or geometry of the rear part of the ski boot sole. Thus, the binding component installed in the alpine ski binding exhibits extremely low deviations from the sole or sole geometry of the ski boot as mounted in the binding. This leads to improved user control over the ski and enhanced user safety by preventing accidental release of the ski binding.

[0035] Furthermore, an imprint on the user's alpine ski boot, which is located on the side of the heel part of the outer shell of the alpine ski boot by many manufacturers, can be read and specified as the sole length for the manufacture of the clamping part.

[0036] It may be provided that the front end part includes a raised section through which the transverse axis runs.

[0037] By means of such a raised section, attached to or positioned on the front end piece, it is possible to shift the transverse axis of the ski binding adapter further upwards. This raised section increases the distance between the horizontally oriented transverse axis and the ski, thus improving the position and horizontal alignment of the pivoting base plate of the ski binding adapter and, consequently, of the alpine ski boot temporarily mounted on the base plate. This also prevents the alpine ski boot, when fixed to the ski binding adapter, from colliding with the front or rear part of the alpine ski binding, whether stationary or during pivoting movements.

[0038] For example, it is provided that the front end piece and the rear end piece have a substantially flat underside and / or that the base plate has a substantially flat surface.

[0039] The essentially flat undersides of the front and rear binding sections provide defined contact surfaces comparable to the contact surfaces of an alpine ski boot's sole. This is a safety feature for the user, as, for example, a sports shop might require setting a so-called Z-value for the alpine ski binding's release. While this Z-value is set for downhill skiing with the ski boot, rather than the binding adapter, in the binding, the binding adapter allows experienced users to perform a telemark turn. Such a telemark turn requires a rotation angle of nearly 90 degrees between both ski boots and the ski's gliding surface, which can be achieved in all variations.The undersides of the end pieces, as just described, with their defined contact surfaces, ensure the safety of the user.

[0040] The base plate of the ski binding adapter is designed with a substantially flat surface. This allows the user's alpine ski boot, with its substantially flat underside, to be optimally and securely positioned on the flat surface of the base plate, at least temporarily. The user's alpine ski boot may extend beyond the front and / or rear end of the base plate.

[0041] According to another aspect of the invention, a vertical cross-section of the front end part along a longitudinal axis of the clamping part is designed as a trapezoid tapering towards the front part of the alpine ski binding.

[0042] This specially designed geometry enables optimal power transmission from the pivot axis of the alpine ski boot, through the mounting bracket, to the alpine ski binding. This ensures, among other things, that the alpine skis are securely edged during the ascent, with the corresponding power transfer from the legs to the edges of the skis. A rigid base plate, resistant to bending and torsional forces, along with a secure clamping of the alpine ski boot onto the base plate, guarantees this optimal power transmission from the user's legs, through the ski boot, to the mounting bracket and thus to the ski binding adapter.

[0043] The longitudinally extended, one-piece clamping element has a longitudinal axis. When the clamping element of the ski binding adapter is inserted into the alpine ski binding, the longitudinal axis of the clamping element runs parallel to a longitudinal axis of the ski. It is advantageous if a vertical cross-section of the front end of the clamping element is designed along its longitudinal axis as a trapezoid that tapers towards the front of the alpine ski binding, thus essentially replicating the front part of the alpine ski boot sole. This replica improves the robust fixation of the clamping element in the alpine ski binding and therefore increases the safety of the ski binding adapter user.

[0044] According to an additional aspect of the invention, a base is provided in the area of ​​the rear end part on an upper side of the clamping part, which is designed for at least temporary reception of a rear part of a sole of the alpine ski boot temporarily arranged on the ski binding adapter or as a lower stop for the pivoting base plate.

[0045] A base can be provided to ensure that the sole of the alpine ski boot mounted on the base plate is essentially horizontally aligned. This base is located, for example, on the upper side of the clamping part in the area of ​​the rear end section and extends away from the ski. The base forms a contact surface that is essentially parallel to a surface of the ski. The length of the base, and thus the distance of the contact surface from the ski, is preferably designed such that the sole of the alpine ski boot mounted on the base plate is almost horizontally aligned in a lower, non-pivoted position. A deviation from an almost horizontal position of up to 10 degrees can also be provided and does not impair the function of the ski binding adapter.

[0046] When ascending a mountain using the ski binding adapter, the rear lower part of the alpine ski boot sole rests at least temporarily on the base's contact surface with each step. In a particular embodiment where the pivoting base plate extends beyond the contact surface of the base, the base's contact surface serves as a lower stop for the pivoting base plate with each step.

[0047] For example, it is provided that an adjustable eccentric element is arranged on the clamping part, by means of which the height of a support surface of the base can be changed, whereby the adjustable eccentric element can be operated by a ski pole.

[0048] As explained above, when ascending a mountain using the ski binding adapter, the rear lower part of the alpine ski boot sole is at least temporarily picked up and placed down on the base's contact surface with each step. Advantageously, the distance between the base's contact surface and the ski's surface can be adjusted within a predetermined range using the adjustable eccentric element. This predetermined range can be between 10 mm and 50 mm, meaning the base's length can be increased by 10 mm to 50 mm. Increasing the base's length, while keeping the ski binding adapter's transverse axis in the same position, increases the angle Ν formed between the ski's surface and the lowest possible position of the alpine ski boot sole, which is pivotally mounted in the ski binding adapter.In this way, the ski binding adapter can be adjusted to the user's changing terrain steepness. For example, on relatively gentle slopes or flat sections, the angle ∝ between the sole of the ski boot and the ski's surface can be 0 degrees in the lowest position and 90 degrees in the highest position. On steeper slopes, the angle ∝ between the sole of the ski boot and the ski's surface can be 15 degrees in the lowest position and 90 degrees in the highest position. The highest position corresponds to the maximum rotation angle of the ski boot sole during a kick turn.In this kick turn, starting from a position with the alpine skis essentially parallel, one ski is lifted completely off the ground and rotated in the air to face the new direction of travel for the ascent. The second ski is then also lifted and rotated in the air so that, after completing the kick turn, it is again essentially parallel to the first ski. In contrast, during a normal walking motion while ascending, the highest lifted position typically does not exceed 70 degrees.

[0049] For example, the adjustable eccentric element, and thus the distance between the base's contact surface and the ski's surface, can be adjusted using the user's ski pole. This allows the user to easily adjust the distance while standing and during the ascent. For this purpose, the adjustable eccentric element can be equipped with an adjustment mechanism that protrudes from the ski binding adapter or folds out over the alpine ski boot (e.g., laterally), making it accessible with the user's ski pole.

[0050] As an alternative to the adjustable eccentric element, a folding lever, also operated with the user's ski pole, can be integrated into the ski binding adapter. This lever adjusts the distance between the base's contact surface and the ski's surface when folded from its resting position to its operating position. This increases the distance between the ski and the contact surface for the rear part of the ski boot's sole or the position of the lower stop for the pivoting base plate. This allows the angle Ν to be gradually increased, for example, to facilitate climbing on varying terrain. The power transmission from the ski boot via the ski binding adapter to the ski is not negatively affected, as the power transmission occurs primarily via the front pivot axis.

[0051] An electrical drive element, particularly one that can be remotely controlled, can be arranged on the adjustable eccentric element to adjust the position of the adjustable eccentric element and thus to adjust the height of the base's support surface.

[0052] It is particularly advantageous if the position of the adjustable eccentric element is adjusted by means of an electric drive unit integrated into the ski binding adapter. This allows the ski binding adapter to be adapted to changing terrain gradients without the need for any protruding or fold-out adjustment mechanisms. The electric drive unit is designed for remote control, for example, via a remote control included with the ski binding adapter. Alternatively, adjustment can be made using a mobile application, also known as an app. This allows for adjustment without the skier having to bend down or stop while climbing, and can also be voice-controlled via Bluetooth and an app.

[0053] In one embodiment of the invention, the clamping element is longitudinally symmetrical along its extension parallel to the ski. This means that, viewed from above, the clamping element is symmetrical along its longitudinal axis when viewed from the alpine ski binding. An advantage of such a symmetrical design is that the left clamping element is identical in form to the right clamping element and is therefore interchangeable between alpine skis. The clamping element is specifically designed to be mirror-symmetrical about its longitudinal axis. Since the clamping elements are generally always used in pairs on two alpine skis, there is no risk of confusion between a left and right clamping element on the left or right alpine ski.Another advantage of the identical design is the identical force transmission via the symmetrically designed clamping part to the respective, current uphill edge of the alpine skis when changing the direction of ascent in steeper terrain, with so-called turns and kick turns to change direction.

[0054] The swiveling base plate can have several front adjustment openings and several rear adjustment openings.

[0055] By incorporating a predetermined number of paired front adjustment openings for a locking bar and / or a predetermined number of paired rear adjustment openings for a locking bar into the pivoting base plate of the ski binding adapter, adjustments can be made to accommodate different sizes of alpine ski boots that can be temporarily positioned on the pivoting base plate using at least one locking bar. In particular, adjustments can be made to accommodate different sole lengths of alpine ski boots. These adjustment openings are arranged in pairs opposite each other, especially on the sides of the pivoting base plate. The total number of pairs of front adjustment openings and / or rear adjustment openings can range from one to ten pairs each.In particular, each adjustment opening is designed as an oval hole or as a longitudinal hole, which allows the curved ends of the locking brackets to be inserted.

[0056] In a further embodiment of the invention, it is provided that a first fastening element comprises a substantially U-shaped first locking bracket, which has first curved ends for insertion into the rear adjustment openings or the front adjustment openings and a clamping element arranged in a central area of ​​the first locking bracket, wherein the clamping element is designed to temporarily fix the alpine ski boot to a rear part of the alpine ski boot or a front part of the alpine ski boot.

[0057] The first fastening element of the ski binding adapter can be designed as a first locking bracket, which is essentially U-shaped and has inwardly curved ends at both of its terminations. These ends are designed to be inserted into the adjustment openings, i.e., the paired longitudinal holes arranged opposite each other, and fixed in place under tension. This tension is generated by the user pivoting the clamping element located in the middle of the first locking bracket, for example, onto the rear, upper, protruding part of the sole of the alpine ski boot, thus fixing the alpine ski boot to the base plate of the ski binding adapter. In this example, the front protruding part of the sole of the alpine ski boot is, for instance, positioned in a fixed front receptacle on the base plate.This mount, which is fixed to the base plate, can be modeled after the front part of the alpine ski binding to prevent the alpine ski boot from slipping on the base plate.

[0058] Furthermore, it may be provided that the first fastening element comprises several essentially U-shaped locking brackets, which are arranged on the pivotable base plate and can be operated by a ski pole.

[0059] To facilitate the temporary fixation of the alpine ski boot to the base plate of the ski binding adapter, the first fastening element can be designed with a locking bar and a tensioning element attached to it, such that the user can operate this mechanism to release the alpine ski boot with a ski pole. Release is achieved similarly to releasing an alpine ski boot from an alpine ski binding, by applying downward and backward pressure with the ski pole onto a corresponding contact surface in the tensioning element.

[0060] It is particularly advantageous if a second fastening element comprises a substantially U-shaped second locking bracket, which has second curved ends for insertion into the front adjustment openings or the rear adjustment openings and a central area, wherein the central area is designed to be temporarily fixed to a front part of the alpine ski boot or a rear part of the alpine ski boot.

[0061] The second fastening element of the ski binding adapter can be designed as a second locking bar, which is essentially U-shaped and has two inwardly curved ends at its two terminations. These ends are designed to be inserted into the adjustment openings, i.e., the paired longitudinal holes arranged opposite each other, and fixed in place under tension. This tension is created when the user pivots the middle section of the second U-shaped locking bar, for example, onto the front, upper, protruding part of the ski boot sole, thus fixing the ski boot to the base plate of the ski binding adapter. In this example, the rear protruding part of the ski boot sole is, for instance, positioned in a rear recess fixed to the base plate.

[0062] For example, the ski binding adapter further includes at least one sensor designed to wirelessly transmit data indicating step frequency and / or ski tilt angle to a mobile data processing device.

[0063] In this way, information such as a user's step frequency while climbing a mountain is recorded and made available to the user for immediate display or subsequent analysis. Such information can also include the ski tilt angle or slope angle, or other data such as GPS-based or GALILEO-based position data, altitude data, or heart rate.

[0064] In another variant, the ski binding adapter is designed such that the difference between (a) the sole length of the alpine ski boot and / or the binding width of the alpine ski binding and (b) the length of the clamping part is less than 3 mm, in particular equal to or less than 1 mm.

[0065] A particular advantage of the present invention is that the clamping element of the ski binding adapter is precisely adapted to the existing sole length of the alpine ski boot and / or the binding width of the alpine ski binding mounted on the ski and is manufactured with exacting tolerances. Such low tolerances as to be less than 3 mm can be achieved between (a) the sole length and / or the binding width of the alpine ski binding and (b) the length of the clamping element. In particular, these tolerances are equal to or less than 1 mm. Thus, the clamping element, which replicates the sole of the alpine ski boot as it would otherwise be arranged in the alpine ski binding, is manufactured with minimal tolerances, adapted to the sole length of the alpine ski boot and / or the binding width, and thereby ensures both a robust attachment of the ski binding adapter in the alpine ski binding and improved safety for the user.

[0066] Such an exact replica of the front and rear areas of the sole of the alpine ski boot, i.e., the areas with which the alpine ski boot is usually fixed in the alpine ski binding mounted on a ski, in contour, shape and geometry with the same sole length and sole thickness, allows the user to maintain the release values ​​set on the alpine ski binding, in particular the Z-value.

[0067] For example, the clamping part of the ski binding adapter is an additively manufactured component, especially one-piece manufactured using 3D printing.

[0068] The manufacturing of the one-piece clamping part of the ski binding adapter using an additive manufacturing process in 3D printing enables the replication of the sole length, sole thickness, and, in particular, the front and rear sections of the alpine ski boot's sole in terms of contour, shape, and / or geometry. This is achieved in the front and rear sections of the clamping part, with a length and shape individually adapted to the sole length of the alpine ski boot and / or the binding width, with extremely low tolerances of 1 mm or less. Due to the additive manufacturing process and the one-piece, or monolithic, design of the clamping part, it is produced with a predetermined flexural and torsional stiffness.These two parameters can be selected through different designs of the clamping part, in particular through the geometry, internal stiffening ribs, material selection, wall thicknesses and manufacturing processes, so that both the bending stiffness and the torsional stiffness of the clamping part reach or even exceed the values ​​of the alpine ski, in order to enable an optimized force transmission and an optimized force transmission from the alpine ski boot to the alpine ski.

[0069] The clamping element may be made of a metallic material such as aluminum or titanium, or of a plastic such as nylon or a polyamide such as PA6 or PA66 or PA11 or PA12 or polycarbonate (PC) or a hard plastic such as acrylonitrile butadiene styrene copolymer (ABS) or a polyetheretherketone (PEEK) or a fiber-reinforced variant of the aforementioned materials (e.g. using glass fibers or carbon fibers).

[0070] Certain plastics, such as PA11, can be produced in an environmentally friendly and sustainable way. For example, PA11 is a high-performance thermoplastic derived from renewable resources. Unlike conventional petroleum-based nylons, PA11 is made from castor oil, meaning that clamping components made from this material can be shredded and recycled.

[0071] Glass fibers or carbon fibers can be used for fiber reinforcement. In particular, for a component manufactured additively using 3D printing (AM: "Additive Manufacturing") in one piece, different materials are used depending on the 3D printing process (SLS: Selective Laser Sintering, SLA: Stereolithography, FDM / FFF: Fused Deposition Modeling / Fused Filament Fabrication, MJF: Multi Jet Fusion, or similar) to achieve specific technical parameters such as stiffness, increased fracture toughness, optimized impact resistance, ensured UV resistance, or minimized water absorption. The long-term behavior can also be improved by selecting the appropriate manufacturing process for the mounting part, keeping degradation and material fatigue within acceptable limits.

[0072] For example, the one-piece clamping element incorporates cavities for weight reduction. This one-piece clamping element can be manufactured using additive manufacturing with predefined cavities to reduce weight, save material, and optimize costs. In this case, the clamping element can essentially have a central cavity extending longitudinally within its interior. In one specific embodiment, the clamping element features several internally arranged, honeycomb-like cavities, designed as three-dimensionally curved ribs. Another embodiment features two-dimensional ribs or internal walls.

[0073] In another variant, the one-piece clamping part is designed as a three-dimensional, open lattice structure with multiple internal cavities, in order to achieve a certain weight optimization, particularly through a 3D printing process, while maintaining high bending stiffness and torsional stiffness, as well as for removing unsolidified material after 3D printing.

[0074] In one special variant, the clamping part of the ski binding adapter is a component manufactured in one piece using injection molding for plastics.

[0075] In another special variant, the clamping part of the ski binding adapter is manufactured as a single piece using a casting or injection molding process for aluminum. Here, liquid aluminum is injected into a steel mold, usually under high pressure, similar to plastic injection molding. This allows for high precision, high dimensional accuracy, and a high surface finish. This process offers cost advantages for high production volumes with specific sole lengths or shoe sizes, while simultaneously resulting in a low weight for the clamping part.

[0076] Regardless of the manufacturing process used for the one-piece clamping component, it can be advantageous if the ski binding adapter is suitable for both alpine ski bindings and GripWalk ski bindings. GripWalk ski bindings are compatible with both standard alpine ski boot soles and special GripWalk ski boot soles. Therefore, GripWalk ski boots with their GripWalk soles can be attached to the swiveling base plate, just like a standard alpine ski boot.

[0077] The ski binding adapter can also be designed to be compatible with so-called hybrid ski boots. Hybrid ski boots are ski boots that combine the features of alpine and touring ski boots. They are also known as "all-mountain ski boots" or "freeride ski boots." With this type of ski boot, the user can choose whether to use the ski binding adapter in the second version, i.e., with a pin adapter, or in the first version, i.e., with a swiveling base plate. Converting the ski binding adapter between these two versions can preferably be done without modifying the clamping part, for example, using replacement parts and existing mounting surfaces. This makes the ski binding adapter an attractive and versatile option for alpine skiers who ski both on and off-piste.

[0078] Exemplary embodiments of the invention are described below with reference to the figures, wherein Fig. 1 shows a ski binding adapter in a first embodiment of the invention in a side view; Fig. 2 shows a perspective view of the ski binding adapter from behind and above; Fig. 3 shows a view of the ski binding adapter from behind; Fig. 4 shows a side view of the clamping part; Fig. 5 shows a top view of the clamping part; Fig. 6 shows the ski binding adapter arranged in an alpine ski binding mounted on a ski; Fig. Figure 7 shows an alpine ski boot mounted on the ski binding adapter in a perspective view; Fig. Figure 8 shows a second version of the ski binding adapter with a pin adapter; Fig. Figure 9 shows a second version of the ski binding adapter with the alpine ski boot fixed in the pin adapter; Fig. 10 shows a sectional view of the additively manufactured clamping part in a first embodiment; Fig. 11 shows a sectional view of the additively manufactured clamping part in a second version; Fig. 12 shows a sectional view of the additively manufactured clamping part in a third embodiment; and Fig. Figure 13 shows an open lattice structure for the clamping part.

[0079] In the different figures, identical parts are always labeled with the same reference symbols, which is why they are generally described only once. The terms "first," "second," etc., used above and below, serve only for the purpose of differentiation. In particular, their use should not imply any order or priority of the objects mentioned in connection with these terms.

[0080] In the Fig. Figure 1 shows a ski binding adapter 1, which is designed for at least temporarily connecting an alpine ski boot 2 with an alpine ski binding 4 mounted on a ski 3, wherein the alpine ski boot 2, the ski 3 and the alpine ski binding 4 are in the Fig. 1 are not shown. Fig. Figure 1 shows the first embodiment of the invention.

[0081] The ski binding adapter 1 comprises a longitudinally extended, one-piece clamping part 6, the length 5 of which is adapted to a sole length of the alpine ski boot and / or a binding width of the alpine ski binding 4. This clamping part 6 has a middle section 7, a front end section 8 and a rear end section 9.

[0082] Furthermore, the ski binding adapter 1 in the Fig. In the first variant shown in Figure 1, a base plate 10 is mounted on which at least one pivotable fastening element 11 is arranged. In the example of the Fig. A first rear fastening element 11a and a second front fastening element 11b are arranged on the base plate 10. The first rear fastening element 11a has a substantially U-shaped first locking bracket, the first curved ends 12 of which are inserted into rear adjustment openings 13. A clamping element 14 is arranged in a central region of the first locking bracket of the fastening element 11a, which is designed to temporarily fix the alpine ski boot 2 (not shown) to a rear part of the alpine ski boot 2.

[0083] The second front fastening element 11b has a substantially U-shaped second locking bracket, the second curved ends 15 of which are inserted into front adjustment openings 16. The second front fastening element 11b has a central area designed to temporarily fix the alpine ski boot 2 (not shown) to a front part of the alpine ski boot 2.

[0084] Thus, the alpine ski boot 2 is positioned and fixed at least temporarily on the base plate 10 of the ski binding adapter 1 by means of the first rear fastening element 11a and by means of the second front fastening element 11b, in order to enable the user to ascend in mountainous terrain without a lift.

[0085] The base plate 10 is pivotably connected to the clamping part 6 about a transverse axis 17. This pivotability is described in the Fig. Figure 1 is represented by a double arrow. The transverse axis 17 is arranged running in the area of ​​the front end part 8 of the clamping part 6. In particular, the transverse axis 17 runs through a raised section 25 in the area of ​​the front end part 8 of the clamping part 6. By means of such a raised section 25, the distance of the horizontally oriented transverse axis 17 to the ski 3 is increased, which improves the position or horizontal alignment of the pivoting base plate 10 of the ski binding adapter 1 and thus of the alpine ski boot 2 temporarily arranged on the base plate 10.

[0086] On the clamping part 6, a base 19 is arranged on an upper surface 18 of the clamping part 6 in the area of ​​the rear end part 9. This base 19 has a bearing surface 20, which is designed to at least temporarily receive a rear part of a sole 21 of the alpine ski boot 2 temporarily arranged on the ski binding adapter 1. In a Fig. In the embodiment not shown, in which the base plate 10 is longer and extends into the area above the base 19, the support surface 20 is designed as a lower stop for the pivotable base plate 10.

[0087] In the example of the Fig. Figure 1 is the pivoting base plate 10, shown in the lower position when an alpine ski boot 2 is mounted on the base plate 10 of the ski binding adapter 1. As the user ascends the mountain, the base plate pivots between this lower position and an upper position (not shown). In one example, this pivoting occurs within an angle o c 22 between the sole 21 of the alpine ski boot 2 and a surface of the ski 3 (not shown) between 0 degrees in the lowest position and 90 degrees in the highest position.

[0088] The Fig. Figure 2 shows a perspective view of the ski binding adapter 1 from the rear and top. Fig. Figure 2 also shows the first version of the ski binding adapter 1. In the Fig. 2 are already for Fig. The components of the ski binding adapter 1 described above can be identified; therefore, reference can be made to the above description for the individual elements.

[0089] The Fig. Figure 2 shows that the base plate 10 has a U-shaped, downwardly open cross-section and is provided, for example, with a rectangular central recess 23, without impairing the bending strength and torsional stiffness of the base plate 10. The essentially U-shaped design of the second locking bracket or fastening element 11b in the front area of ​​the base plate 10 is also visible. The essentially U-shaped first locking bracket, i.e., the first fastening element 11a, is also shown in the Fig. Figure 2 shows the clamping element 14, wherein the clamping element 14 is pivotably arranged in the central area of ​​the fastening element 11a about a pivot axis 24, as indicated by the corresponding double arrow. This pivotability of the clamping element 14 enables the robust fastening of the alpine ski boot 2 to the base plate 10 of the ski binding adapter 1. For this purpose, the fastening element 11a, with its opposing first curved ends 12, is inserted into the penultimate longitudinal holes of the rear adjustment openings 13, which are arranged in the base plate 10 in a pair opposite each other. Fig. Only the front longitudinal holes of the paired, opposite each other, inserted into the base plate 10 are visible.

[0090] In the view of Fig. Figure 2 shows that the middle section 7 is narrowed, whereas the front end section 8 and the rear end section 9 are widened and rounded. It is further shown that the outer contour, shape, and geometry of the front end section 8 correspond to an inner contour, shape, and geometry of an unspecified front section of the alpine ski binding 4a, and that the rear end section 9 corresponds to an inner contour, shape, and geometry of an unspecified rear section of the alpine ski binding 4b.

[0091] On the one hand, the length 5 of the clamping part 6 precisely replicates the sole length of the alpine ski boot 2. Additionally, the front end piece 8 replicates the front section of the sole 21 of the alpine ski boot 2, and the rear end piece 9 replicates the rear section of the sole 21 of the alpine ski boot 2. Such a replica with the same sole length and thickness allows the user to maintain the release values ​​set on the alpine ski binding 4, particularly the Z-value.

[0092] Additionally, in the Fig. 2 to recognize that the base 19 is tapered in the direction of its bearing surface 20.

[0093] The Fig. Figure 3 shows a rear view of the ski binding adapter 1. In this view, the rear end piece 9 of the clamping part 6 can be seen in its design, which is adapted in outer contour, shape and geometry to the inner contour, shape and geometry of the rear part of the alpine ski binding 4b (not shown). Above the rear end piece 9, the base 19 with the bearing surface 20 is shown.

[0094] The first rear fastening element 11a is shown inserted with its first curved ends 12a and 12b into rear adjustment openings 13a and 13b. The second front fastening element 11b is shown inserted with its second curved ends 15a and 15b into front adjustment openings 16a and 16b. In the illustration of the Fig. 3 The transverse axis 17, about which the base plate 10 is pivotably arranged, and the rotation axis 24, about which the clamping element 14 is pivotably arranged, can also be seen.

[0095] In the Fig. Figure 4 is a side view of the clamping part 6 and in the Fig. Figure 5 shows a top view of the clamping part 6. In the Fig. 4 and Fig. Figure 5 shows the clamping part 6 of the ski binding adapter 1 without any other parts.

[0096] The sections front end piece 8, middle piece 7, and rear end piece 9 of the clamping part 6 are visible in both views. The raised section 25, through which the transverse axis 17 runs, is also shown in the area of ​​the front end piece 8. This raised section increases the distance between the horizontally oriented transverse axis 17 and the ski 3, thus improving the position and horizontal alignment of the pivoting base plate 10 of the ski binding adapter 1 and, consequently, of the alpine ski boot 2 temporarily mounted on the base plate 10. The ski 3, the pivoting base plate 10, and the alpine ski boot 2 are shown in the Fig. 4 and Fig. 5 not shown.

[0097] In the Fig. Figure 5 shows that the middle section 7 is narrowed, whereas the front end section 8 and the rear end section 9 are wider and rounded compared to the middle section 7. In particular, it is evident in the Fig. 5 to recognize that the front end part 8 is modeled on the front area of ​​the sole 21 of the alpine ski boot 2 and the rear end part 9 is modeled on the rear area of ​​the sole 21 of the alpine ski boot 2.

[0098] In the Fig. 5 On the raised section 25, four mounting openings 26 can be seen as examples, which allow for the optional mounting of a pin adapter 27 (not shown) on the clamping part 6 according to the second version of the ski binding adapter 1.

[0099] In the example of the Fig. Figure 5 further shows that the clamping part 6 shown is symmetrical in its longitudinal extension along a longitudinal axis 28 in a view from above.

[0100] The Fig. Figure 6 shows the ski binding adapter 1, according to the first embodiment, inserted into an alpine ski binding 4 mounted on a ski 3. Specifically, the clamping part 6 of the ski binding adapter 1 is inserted and fixed in the alpine ski binding 4 mounted on the ski 3. The alpine ski binding 4 has a front part 4a and a rear part 4b. The front end piece 8 of the clamping part 6 is inserted and fixed into the front part 4a of the alpine ski binding 4, and the rear end piece 9 of the clamping part 6 is inserted and fixed into the rear part 4b of the alpine ski binding 4. An alpine ski boot 2 is arranged on the base plate 10, which is pivotably mounted on the clamping part 6 about the transverse axis 17. To fix the alpine ski boot 2 to the base plate 10, the second fastening element 11b is provided in the front area of ​​the sole 21 of the alpine ski boot 2, which engages with its second curved ends 15 in a pair of the front adjustment openings 16.Furthermore, to fix the alpine ski boot 2 to the base plate 10 in the rear area of ​​the sole 21 of the alpine ski boot 2, the first fastening element 11a is provided, the first curved ends 12 of which engage with a pair of the rear adjustment openings 13. To fix the sole 21 of the alpine ski boot 2 in the rear area, the clamping element 14, pivotably arranged on the first fastening element 11a, is also provided, which exerts pressure on the rear area of ​​the sole 21 of the alpine ski boot 2 and thus presses the alpine ski boot 2 against the surface of the base plate 10.

[0101] In the Fig. Figure 6 shows the alpine ski boot 2 in the ski binding adapter 1 in the lower position, in which the sole 21 of the alpine ski boot 2 rests on the support surface 20 of the base 19. When ascending the mountain, the user pivots the base plate 10 with the alpine ski boot 2 to an upper position, which is in the Fig. 6 is not shown.

[0102] The Fig. Figure 7 shows the alpine ski boot 2 arranged on the ski binding adapter 1 in a perspective view. For a better understanding of the invention, the following is shown in the Fig. Figure 7 shows an alpine ski boot 2 arranged on the base plate 10 of the ski binding adapter 1 in a perspective view from a slightly rear angle, without the ski 3. In this view, the alpine ski boot 2 is also shown in the lower position in the ski binding adapter 1, in which the sole 21 of the alpine ski boot 2 rests on the support surface 20 of the base 19.

[0103] In the Fig. Figure 8 shows a second embodiment of the ski binding adapter 1 with a pin adapter 27. In this second embodiment of the ski binding adapter 1, a clamping element 6, already described for the first embodiment of the ski binding adapter 1, is provided. The pin adapter 27 is arranged on the raised section 25 of the clamping element 6, i.e., above the area of ​​the front end piece 8. In the example of the Fig. The pin adapter 27 comprises a U-shaped mounting plate 29 with pivotable side plates, the mounting plate 29 being fixed by means of several fastening elements 30, such as screws, inserted into the mounting openings 26 provided on the raised section 25. In this way, the mounting plate 29 of the pin adapter 27 is fixed to the clamping part 6. The provided mounting openings 26 are shown by way of example in the Fig. Figure 5 shows the pin adapter 27. It further comprises two bolt-like fixing means 31. To accommodate the alpine ski boot 2, the pin adapter 27 has fixing means receptacles, also referred to as pin inserts 32. These fixing means receptacles, or the pin insert 32, correspond to the fixing means 31 and are arranged in pairs opposite each other in the front area of ​​the sole 21 of the alpine ski boot 2.

[0104] The Fig. Figure 9 shows the second embodiment of the ski binding adapter 1 with an alpine ski boot 2 fixed to the ski binding adapter 1 by means of the pin adapter 27. In this illustration, the alpine ski boot 2 is pivotably fixed to the U-shaped mounting plate 29 of the pin adapter 27 by means of the bolt-like fixing means 31. Fig. Figure 9 shows the alpine ski boot 2 in the ski binding adapter 1 in a position that is at least raised, in which the sole 21 of the alpine ski boot 2 is spaced away from the contact surface 20 of the base 19.

[0105] The Fig. Figure 10 shows a sectional view of the additively manufactured clamping part 6 in a first version.

[0106] The Fig. Figure 11 shows a sectional view of the additively manufactured clamping part 6 in a second version.

[0107] The Fig. Figure 12 shows a sectional view of the additively manufactured clamping part 6 in a third version.

[0108] The clamping part 6, manufactured in one piece using an additive process, for example in 3D printing, is produced with predefined cavities 33 to reduce weight, save material and optimize costs. In a first variant, the clamping part 6 has several honeycomb-like cavities 33 distributed throughout its interior, as exemplified in the Fig. 10 and Fig. Figure 11 is shown. In a second variant, the clamping part 6 essentially has a central cavity 33 extending longitudinally inside the clamping part 6, which is shown in the Fig. Figure 12 shows that, in addition, two material extraction openings 34 are arranged on the clamping part 6, through which unsolidified powder material can be extracted during additive manufacturing or removed by a material irradiation process, as is common in additive manufacturing processes or 3D printing using powder material, for example in selective laser sintering (SLS).

[0109] The Fig. Figure 13 shows an embodiment or variant of the clamping part 6 with an open, three-dimensional lattice structure, manufactured using a 3D printing process, for further weight optimization while maintaining the stiffness values ​​of the clamping part 6.

[0110] It is understood that the described ski binding adapter 1 and its components can be modified by a specialist.
