Tension lever as a punched or cut part

Description

[0001] The invention relates to a toe piece for a touring ski binding, which has a clamping device for holding a ski boot in the touring ski binding, wherein the clamping device comprises a clamping lever which is at least partially a punched part punched out of a material plate.

[0002] Touring ski bindings are used not only for downhill skiing but also primarily for ascending slopes. In addition to the weight of the touring ski binding, price is also a factor that influences the customer's purchasing decision. Potential savings in manufacturing costs can be realized, for example, by reducing the production time for individual touring ski binding components. This time saving can be achieved, for example, by replacing a standard manufacturing process with a different, more cost-effective, simpler, and / or faster manufacturing process. This means that the manufacturer is tasked with reviewing the costs incurred at every manufacturing step of each touring ski binding component and seeking more cost-effective manufacturing methods.

[0003] This object is achieved by the subject matter of claim 1. Advantageous further developments are described in the claims dependent on claim 1.

[0004] The touring ski binding "Plum R150", for example, has a generic toe piece (URL: https: / / www.fixation-plum.com / de / our-bindings / 1210-race-150.html).

[0005] The subject matter of the invention is a toe piece for a touring ski binding, comprising a base and a bearing arrangement which is designed to pivotably hold a ski boot about a transverse ski axis running transversely to a ski binding longitudinal axis, so that the ski boot can be moved between a first pivoting position in which a heel section of the ski boot is closer to the ski, and a second pivoting position in which the heel section of the ski boot is away from the ski, wherein the toe piece has a clamping device with which the bearing arrangement can be locked in such a way that pivoting of the ski boot is possible, but release of the ski boot from the bearing arrangement is prevented even when a fall-triggering force is exerted, wherein the clamping device comprises a clamping element and a clamping lever, wherein the clamping lever can be connected to the base in a pivot joint.The tensioning lever has a free end in the longitudinal direction of the lever, which comprises a tensioning lever head with a tensioning lever mouth. The tensioning lever mouth is designed to be coupled to a mechanism of the toe piece, which tensions and releases the bearing arrangement of the toe piece.

[0006] According to the invention, the clamping lever, or at least a portion of the clamping lever, is punched out of a sheet of material as a stamped part. The stamped part can be single-layered or composed of multiple layers, each of which is manufactured as a stamped part. Two or more layers can be joined to form the aforementioned part of the clamping lever following the stamping process.

[0007] In addition to the touring ski binding, the touring ski binding also includes a heel piece, in which the ski boot is held at a rear end or heel end during downhill skiing. The heel piece can be moved linearly relative to the ski, for example, or pivoted about an axis that is directed upwards substantially perpendicular to a ski surface, in order to transfer the touring ski binding from downhill mode to touring mode. The heel piece can be a known heel piece, for example with an automatic mechanism that presses against a surface of a rear end of the ski boot sole, or a heel piece with at least one engagement element that engages with at least one counter-engagement element formed in the ski boot sole in the region of the heel end, or another known heel piece.In touring mode of the touring ski binding, the heel piece can form at least one climbing aid and / or comprise at least one climbing aid that is adjustable relative to the heel piece.

[0008] The bearing arrangement can consist of two engagement elements that are opposite one another with respect to a central longitudinal axis of the ski and are each connected in the region of a first free end of a first or second arm, wherein a second free end of the first and second arms is pivotally held in the toe piece. The first and second arms can be pivoted synchronously into a first position and into a second position by means of the mechanism. In the first position, the two engagement elements are spaced apart by a maximum distance such that a user can step into the toe piece with a ski boot. In the second position, the two engagement elements are spaced apart by a distance that is smaller than the maximum distance in the first position. In the second position, the two engagement elements define a pivot axis for the pivoting movement of the ski boot.In the second position, the engagement elements can engage with openings formed in the sole of the ski boot, thereby connecting the ski boot to the ski at the front end or toe end in touring mode. Ski bindings with this type of toe piece are also called pin bindings.

[0009] Most touring ski bindings have tensioning devices to lock the bearing assembly during ascent, allowing the ski boot to pivot, but preventing the ski boot from detaching from the bearing assembly even when a fall-triggering force is applied. The unlocked state of the bearing assembly is desirable during downhill skiing, allowing the touring ski binding to open when a fall-triggering force is sufficiently high, releasing the ski boot and thus preventing injury.

[0010] The release of the ski boot from the touring ski binding in the event of a fall, lateral load or load in or against the direction of travel above an adjustable limit can be achieved by the front piece and / or the rear piece.

[0011] The material of the material plate or plates can be a plastic, in particular a reinforced plastic, steel, aluminum, magnesium, or an alloy comprising at least one of these materials. Alternative materials are possible, as long as they have the necessary strength under the expected environmental conditions for a touring ski binding. This means that with a multi-layer construction, the aforementioned part of the tensioning lever can be formed from layers of one material or from layers of different materials. If several layers are bonded together, not all layers need to be fully bonded, which can save material and weight.For example, in a multi-layered construction of the clamping lever, at least one layer can be made of a solid material, in particular a metal, while at least one of the other layers, for example made of plastic, can have a skeleton structure, preferably with a closed outer side, which can form a lateral surface of the clamping lever. It can also be advantageous, for example, to arrange a corrosion-prone material between two layers where no corrosion problems are expected over the lifetime of the product.

[0012] The manufacturing technique chosen for producing the clamping lever, in particular the at least one solid material part, is punching out of the material plate by means of a punching device or punch.

[0013] In addition to the connection to the base in the swivel joint, the clamping lever can be connected to the clamping element in a further swivel joint, particularly in a captive manner. A rivet can form a rotation axis of the further swivel joint. The rivet can hold the clamping lever in the further swivel joint in a rotatable or pivotable manner and captive in the clamping element.

[0014] The tensioning lever can be elongated and has a free end in the tensioning lever or lever longitudinal direction, which encompasses the tensioning lever head with the tensioning lever mouth. A tensioning lever longitudinal axis can run parallel to the ski binding longitudinal axis, at least in one pivot position, possibly in a pivot position of the tensioning lever that is only theoretically achievable.

[0015] The clamping lever mouth is designed to be coupled to a mechanism of the toe piece or to engage with this mechanism. A pivoting movement of the clamping lever can preferably be transmitted to the mechanism. The mechanism can be designed to tension the bearing arrangement of the toe piece so that the ski boot is held in the bearing arrangement, and to relax it to release the ski boot from the bearing arrangement.

[0016] The clamping lever can be formed solely by the at least one stamped part. Alternatively, the clamping lever can be constructed in a sandwich design, wherein the stamped part is arranged between at least one first mold plate and at least one second mold plate, such that one of the mold plates forms a left outer side and another of the mold plates forms a right outer side of the clamping lever. The first mold plate and the second mold plate can be separate mold plates that are individually joined to the stamped part. Alternatively, the first mold plate and the second mold plate can be connected to one another, preferably molded in one piece, and form a clamping lever housing that at least partially encompasses the stamped part.

[0017] The first mold plate and the second mold plate, or the clamping lever housing, can be made of a plastic, preferably using a plastic injection molding or deep-drawing process. They can be three-dimensional, for example, as a hollow body with a molded reinforcement structure, and have a printable surface so that they can be adapted to any design. The mold plates can also be made of a clear or transparent material or plastic, which can be printed on its inside, for example. Finally, the mold plates can have sections made of different materials, for example, they can be manufactured using a two- or multi-component plastic injection molding process or they can include inserts that are overmolded with plastic.

[0018] Preferably, the first mold plate and the second mold plate are joined to the punched part, preferably by positive and / or material bonding. Material bonding can be understood, for example, as a connection by means of an adhesive. An outer peripheral shape of the support surface of the first and second mold plates, which bears against the punched part, can essentially correspond to the outer peripheral shape of the punched part.

[0019] The positive and / or material-locking connection connects the stamped part to the first mold plate and the second mold plate, preferably elastically, so that, for example, a temperature-dependent, different expansion between the stamped part can be compensated for by the elastic connection. It is preferred if the material of the stamped part and the material of the first and second mold plates, or of the clamping lever housing, have a similar, preferably essentially identical, coefficient of linear expansion in a temperature range between -30°C and +40°C, preferably between -25°C and +35°C, and particularly preferably -20°C and +30°C.

[0020] Preferably, the first mold plate and the second mold plate have a longitudinal extent that is smaller than a longitudinal extent of the punched part, so that the clamping lever mouth, or a tongue of the clamping lever mouth, protrudes at least partially beyond the first and the second mold plate in the direction of the mechanism for clamping and releasing the clamping device.

[0021] The stamped part is preferably positively connected to the tension lever housing. The stamped part can in particular be connected to the tension lever housing and secured to the tension lever housing by means of one or more riveted connections. The rivet can be part of the first pivot joint and / or the second pivot joint. In addition, the stamped part can be glued to the molded parts or the tension lever housing. Alternatively, the tension lever housing can be connected to the stamped part via a screw body and / or by means of an adhesive. Finally, one of the stamped part and the tension lever housing can comprise an engagement element that engages with a counter-engagement element of the other of the stamped part and the tension lever housing. The counter-engagement element can, for example, be a slot or a through-opening in the stamped part that is already created during the stamping process, so that no further processing step is necessary.However, the counter-engagement element can also be created in a subsequent machining step. Accordingly, the engagement element can be formed by the clamping lever housing.

[0022] The clamping element can be connected to the clamping lever in a pivot joint, preferably in a captive manner, and can be pivoted relative to the clamping lever in the pivot joint. The clamping lever can be located within the clamping element, at least in one pivot position, with one end facing away from the clamping lever head, meaning that it can be at least partially surrounded by the clamping element.

[0023] As already described, the clamping lever can be connected to the base via an additional pivot joint and can be pivoted relative to the base. The pivot joint, in which the clamping element is connected to the clamping lever, can be positioned after or behind the additional pivot joint in the longitudinal direction of the ski, i.e., closer to the tip of the ski. The base can be designed to be connected directly to a ski or via one or more intermediate elements.

[0024] The tensioning element can have a contact device which is brought into and out of contact with a contact surface of the base when the tensioning element is pivoted about the pivot joint that connects the tensioning element to the tensioning lever. The contact surface serves, for example, as a stop for the contact device of the tensioning element and limits the movement of the tensioning lever in the locked position, i.e. when there is contact between the contact device and the contact surface. The bearing arrangement is locked by the coupling of the tensioning lever to the bearing arrangement via a mechanism, so that a ski boot located in the toe piece cannot detach from the bearing arrangement even if a force is exerted that could trigger a fall. This state is desirable and advantageous when ascending with the touring ski binding.

[0025] The stamped part can have at least three clearly defined sections: a first section which comprises a receptacle or an opening for a joint axis of the rotary joint which connects the clamping lever to the clamping element, a second section which adjoins the first section and which can be designed in such a way that it enables the required mobility of the clamping lever in the front jaw and / or can form a locking mechanism for the contact device in at least one pivoting position of the contact device, and a third section which adjoins the second section and which comprises a receptacle or an opening for the joint axis of the rotary joint which preferably connects the stamped part to the base, and the clamping lever head with the clamping lever mouth.The mold plates or the clamping lever housing can also have these sections, with the exception that the clamping lever head with the clamping lever mouth is not covered or at least only partially covered by the mold plates or the clamping lever housing.

[0026] In other words, the first and / or second mold plate or the clamping lever housing can have at least three regions: a first region comprising a receptacle for the pivot joint that connects the clamping lever to the clamping element; a second region adjoining the first region and designed to form a latch for the contact device when the contact device is in a pivoting position; and a third region adjoining the second region and comprising a receptacle for a pivot joint that preferably connects the stamped part to the base. The stamped part comprises the clamping lever head with the clamping lever mouth; and at least one tongue or part of the tongue of the clamping lever mouth can protrude beyond one end of the first and second mold plates in the longitudinal direction of the front jaw.

[0027] The subject matter of the application is further explained below using an exemplary embodiment, without limiting the invention to the exemplary embodiment shown. Technical features that are essential to the invention and can only be gathered from the figures are part of the scope of the disclosure and can advantageously further develop the subject matter. The figures show in detail: Figure 1: Perspective view of a front jaw; Figure 2: Section along a longitudinal axis through the front jaw of the Figure 1 ; Figure 3: four detailed views of the clamping device of the front jaw of the Figure 1 ; Figure 4:Exploded view of the front jaw of the Figure 1 with clamping lever housing.

[0028] The Figure 1shows a toe piece 100 for a touring ski binding. The toe piece 100 comprises a base 103, via which the toe piece 100 can be connected to a ski (not shown). Furthermore, the toe piece 100 comprises a bearing arrangement 101, which in the exemplary embodiment consists of two pins designed to engage in receptacles of a ski boot (not shown). The bearing arrangement 101 or the pins firmly connect the toe piece 100 to the ski boot in a first position and form an axis that runs in a transverse direction Q to a longitudinal axis L of the toe piece 100. The ski boot can be pivoted about the axis from a first position, in which the ski boot sole runs substantially parallel to an upper side of the ski and the heel section of the ski boot is closer to the ski, to a second position, in which the ski boot sole forms an acute angle with the upper side of the ski and the heel section of the ski boot is further away from the ski.

[0029] In order to move the bearing arrangement from the first position to the second position and preferably to secure it in the respective position, the toe piece 100 comprises a clamping device 1 with a clamping element 10 and a clamping lever 20. The clamping element 10 and the clamping lever 20 are connected to one another at a pivot joint D1. The clamping lever 20 is connected to the base 103 at a pivot joint D2. The clamping lever 20 acts on a mechanism 102 that is connected to the bearing arrangement 101, or rather the pins, in order to move them into the first position, in which the bearing arrangement 101 is connected to the ski boot, and from the first position into a second position, in which the ski boot can be removed from the toe piece 100.

[0030] The clamping lever 20 consists of several parts that are joined together. In the exemplary embodiment, the clamping lever 20 consists of a central part or core that is punched out of a sheet material and is therefore also referred to as a punched part 21.

[0031] The stamped part 21 is preferably formed from a metal, for example, aluminum, steel, magnesium, another suitable metal, or an alloy comprising at least one of the aforementioned metals. However, the central part can also consist of more than one stamped part 21, which are joined together to form the central part. If the central part consists of more than one stamped part 21, the stamped parts 21 can be formed from different materials, for example, from different metals or metal alloys.

[0032] Two mold plates 24, 25 are joined to the stamped part 21, forming a right and a left side of the clamping lever 20. The mold plates 24, 25 can also be made of metal, but they are preferably plastic parts, which are produced, for example, by injection molding, deep-drawing, or another suitable manufacturing process. Suitable plastics include, without claiming to be exhaustive, polypropylene, polyethylene, polystyrene, PMMA, ABS, or ASA / ABS.

[0033] Since weight is always a factor that is taken into account in the development of new ski bindings, the punched part 21 can, for example, have a longitudinal slot in the central area to save weight. This slot is created during the punching process, for example, since this does not require additional time, unlike cutting, for example. Openings at other locations are conceivable, and their suitability can easily be verified by a specialist through testing.

[0034] The mold plates 24, 25 can be shell-shaped, partially shell-shaped, or made of solid material. Shell-shaped or partially shell-shaped mold plates 24, 25 can have integrated reinforcing structures, such as reinforcing ribs, reinforcing studs, etc., to prevent the shell from collapsing or being dented when subjected to force from the side. Finally, the mold plates 24, 25 can be made of different materials in certain areas, for example, different plastics or partially of natural materials, such as compostable natural fibers, to provide a further advantage for the application.

[0035] The Figure 2shows a section through the toe piece 100 along a ski binding longitudinal axis L. The stamped part 21 is clearly visible. The stamped part 21 has an opening or a receptacle 52, which is part of the pivot joint D1 or at least accommodates the pivot joint D1, in which the tensioning element 10 can be rotatably connected to the tensioning lever 20. Furthermore, an opening or a recess 53 is formed in the stamped part 21, which forms part of the pivot joint D2 or at least accommodates the pivot joint D2, in which the tensioning lever 20 can be rotatably connected to the base 103.

[0036] The stamped part 21 comprises, at its end facing the mechanism 102, a clamping lever head 22 with a clamping lever mouth 23. The clamping lever mouth 23 couples with the mechanism 102, so that a movement of the clamping lever 20 is transmitted directly to the mechanism 102. In the Figure 2the tensioning lever 20 presses the mechanism 102 downwards close to the base 103, whereby the contact device 11, or the pins, are pressed against the ski boot (not shown) or into recesses in the ski boot sole.

[0037] The clamping element 10 comprises a contact device 11, which interacts with a contact surface 104 and provides support and security for the clamping element 10, at least in the first position and in the second position. The contact surface 104 is connected to the base 103 or can be part of the base 103, for example, molded in one piece with the base 103. The clamping lever 20 has a recess 28 in a central region, viewed in the lever's longitudinal direction HL, on its side facing the ski. This recess forms a locking mechanism for the contact device 11 and thus also for the clamping element 10 when the clamping element 10 is in a pivoted position. However, the recess 28 can also be due solely to the design of the toe piece and enable the required mobility of the clamping lever 20 in the toe piece.

[0038] The Figure 3shows four detailed views of the clamping device 1 consisting of the clamping device 10 and the clamping lever 20 (Fig. a), a longitudinal section through the clamping device 1 (Fig. b), the clamping lever 20 (Fig. c) and a longitudinal section through the clamping lever 20 (Fig. d).

[0039] Fig. a) shows an embodiment of the clamping device 1 with a clamping element 10 and a clamping lever 20. The clamping element 10 is frame-shaped and comprises a part of the rotary joint D1 and the contact device 11, which in the illustration is located in the recess 28 of the clamping lever 20.

[0040] The clamping lever 20 comprises the stamped part 21 with the clamping lever head 22, the clamping lever mouth 23, and a tongue 27, which is an extension of a lower part of the clamping lever mouth 23 facing the base 103. Furthermore, the clamping lever 20 comprises the mold plate 24 and the mold plate 25, which form the outer sides of the clamping lever 20 and are joined to the stamped part 21. The mold plates 24, 25 can be releasably joined to the stamped part 21 so that they can be replaced, or they can be firmly joined so that they cannot be separated from the stamped part 21 without causing damage.

[0041] Fig. b) shows a longitudinal section through the clamping device of Fig. a). The punched part 21 contains the recess 52, in which the clamping element 10 and the clamping lever 20 are connected to each other in the pivot joint D1, and the recess 53, in which the clamping lever 20 can be connected to the base 103 in the pivot joint D2.

[0042] Fig. c) shows only the clamping lever 20, with the punched part 21 as the central part and the two mold plates 24, 25, which are joined to the punched part 21 on a right and left longitudinal side of the punched part 21, respectively, which are perpendicular to a lever longitudinal axis HL of the punched part 21. In Fig. c) it can be clearly seen that the punched part 21 forms a clamping lever head 22 and a clamping lever mouth 23 at one of its ends in the lever longitudinal direction HL, and the clamping lever mouth 23 comprises a tongue 27 on its side facing the base 103. In the exemplary embodiment, the mold plates 24, 25 cover the entire side surface of the punched part 21 with the exception of the tongue 27. This means that an outer peripheral shape of the mold plates 24, 25 corresponds to an outer peripheral shape of the punched part 21, but without the tongue 27. The tongue 27 protrudes forward beyond the mold plates 24, 25 in the exemplary embodiment.

[0043] Fig. d) shows a longitudinal section through the clamping lever of Fig. c). Fig. d) shows that the recesses 52 and 53 for the swivel joints D1 and D2 are through holes.

[0044] The Figure 4 is an exploded view of the clamping device 1, consisting of the clamping element 10 and the clamping lever 20 and a clamping lever housing 26.

[0045] The clamping element 10 is frame-shaped and includes an opening 52 through which an axle 30 can be inserted, forming part of the pivot joint D1 in which the clamping element 10 is rotatably connected to the clamping lever 20. The axle 30 can, for example, be a rivet that simultaneously connects the clamping element 10 to the clamping lever 20 in a captive manner.

[0046] The clamping element 10 further comprises the contact device 11, which in the exemplary embodiment comprises a contact device axis 11b and a contact device support 11a. The contact device axis 11b is inserted through the opening 54 and then through the contact device support 11a, so that the contact device support 11a is arranged between the two at least partially free ends of the clamping element arms 10a, 10b.

[0047] The stamped part 21 is divided into three sections A1, A2, and A3. The same applies, mutatis mutandis, to the mold plates 24, 25 and the clamping lever housing 26.

[0048] The first section A1 comprises the receptacle 52 and forms an end of the stamped part 21 facing away from the ski boot, which can be connected or is connected to the clamping element 10 in the pivot joint D1. Near its free end, the section A1 has an upwardly projecting nose that forms a first stop 29a for the clamping lever housing 26.

[0049] The second section A2 comprises the recess 28 and, in this embodiment, has a step on its upper side facing away from the base 103, which step forms a second stop 29b for the clamping lever housing 26.

[0050] The third section A3 comprises the receptacle 53, the clamping lever head 22 and the clamping lever mouth 23 with the tongue 27.

[0051] Finally, the Figure 4a clamping lever housing 26, which comprises the two mold plates 24, 25, wherein the two mold plates 24, 25 are connected to one another in a connecting region 26a and form a type of sleeve for the stamped part 21, which partially surrounds the stamped part 21 on the sides and on its upper side facing away from the base 103. In the exemplary embodiment, the connecting region 26a is designed such that its underside facing the base 103, with the first stop 29a and the second stop 29b, positively secures the clamping lever housing 26 at least in the lever longitudinal direction HL. Further connections of the clamping lever housing 26 to the stamped part 21 can be formed by the rotation axes D1, D2, or the axes 30 of these rotary joints D1, D2, which extend through the lever arm 20 or engage in the lever arm.
