Description

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, the clamping device comprising a clamping lever which is at least partially a stamped part or a cut part cut out of a material plate.

Touring ski bindings are primarily used to descend with a ski, as well as to ascend slopes with the ski. In addition to the weight of the touring ski binding, the price is also a factor that influences the customer's purchase decision. A saving potential in manufacturing costs can be realized, for example, by reducing the manufacturing time of individual parts of the touring ski binding. This time saving can be realized, for example, by replacing a manufacturing method accepted as a standard by another, more cost-effective, simpler and / or faster manufacturing method. This means that the manufacturer has the task of checking the costs incurred in every manufacturing step of each touring ski binding part and of looking for more cost-effective ways of manufacturing it.

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

One aspect of the invention relates to a toe piece for a touring ski binding, comprising a base and a bearing arrangement which is designed to hold a ski boot pivotably about a ski transverse axis running transversely to a ski binding longitudinal axis, so that the ski boot can be moved between a first pivot position in which a Heel portion of the ski boot is approximated to the ski, and a second pivot position in which the heel portion of the ski boot of the Ski is removed, wherein the front jaw has a clamping device with which the bearing arrangement can be locked so that pivoting of the ski boot is possible, but a loosening of the ski boot from the bearing arrangement is prevented even when a fall trigger force is exerted, the clamping device having a clamping element and a Comprises tensioning lever, wherein the tensioning lever can be connected to the base in a swivel joint, characterized in that the tensioning lever or at least a part of the tensioning lever is punched out of a sheet of material as a stamped part or cut out as a cut part. In this case, the punched part or the cut part can be a single layer, or it can be made up of several layers, each layer of which was produced as a punched part or as a cut part. Two or more layers can be added to the mentioned part of the clamping lever at the end of the punching or cutting

In addition to the toe piece, the touring ski binding also includes a heel piece in which the ski boot is held at a rear end or heel end during the descent. The rear jaw can be moved linearly relative to the ski, for example, or pivoted about an axis that is directed upwards essentially perpendicular to a ski surface in order to transfer the touring ski binding from the downhill mode to the touring mode. The buttock can be a known buttock, for example with a machine that presses on a surface of a rear end of the ski boot sole, or a heel with at least one engagement element that is in at least one counter-engagement element that is in the ski boot sole in the area of the heel end is formed, engages, or some other known buttock. In the touring mode of the touring ski binding, the buttock can form at least one climbing aid and / or comprise at least one climbing aid that is adjustable relative to the heel.

The bearing device can be two engagement elements opposite one another with respect to a ski center longitudinal axis, which are each connected in the area of a first free end of a first or second arm, a second free end of the first and second arms being held pivotably in the front jaw. The first and the second arm can be pivoted synchronously into a first position and into a second position by means of the mechanism. Point in the first position the two engagement elements are at a maximum distance from one another, so that a user can step into the toe piece with a ski boot. In the second position, the two engagement elements are spaced apart from one another which is smaller than the maximum spacing of 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 in openings which are formed in a ski boot sole of the ski boot and thereby connect 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 referred to as pin bindings.

Most touring ski bindings have tensioning devices in order to lock the bearing arrangement during an ascent with the ski, so that the ski boot can be pivoted, but the ski boot cannot be released from the bearing arrangement even when a fall-triggering force is exerted. The unlocked state of the bearing arrangement is desired when skiing down, so that the touring ski binding can open with a sufficiently high fall trigger force, release the ski boot and thus avoid injuries.

The loosening of the ski boot from the touring ski binding in the event of a fall, side loading or loading in or against the direction of travel above an adjustable limit value can be done through the toe and / or the heel.

The material of the material plate or the material plates can be a plastic, in particular a reinforced plastic, a steel, an aluminum, a magnesium or an alloy which comprises at least one of these materials. Alternative materials are possible as long as they have the necessary strength in the expected environmental conditions for a touring ski binding. This means that in the case of a structure made up of several layers, said part of the tensioning lever can be formed from layers of one material or from layers of different materials. If several layers are connected to one another, not all layers have to be full-surface, which saves material and weight. For example In the case of a multi-layer structure of the tensioning lever, at least one layer can consist of a solid material, in particular a metal, while at least one of the further layers, for example made of plastic, can have a skeletal structure, preferably with a closed outer side, which form a lateral surface of the tensioning lever can. It can also be advantageous, for example, to arrange a corrosion-prone material between two layers in which no corrosion problems are to be expected for the life of the product.

As manufacturing techniques for the manufacture of the clamping lever, in particular the at least one solid material part, punching out of the material plate by means of a punching device or punch, or the cutting out of the clamping lever from the material plate by laser cutting, water jet cutting, wire cutting or milling are not finally possible. Other manufacturing techniques or manufacturing processes that are not mentioned here but are considered by a person skilled in the art are not excluded.

In addition to the connection in the swivel joint with the base, the clamping lever can be connected or connected to the clamping element in a further swivel joint, in particular in a captive manner. A rivet can form an axis of rotation of the further swivel joint. The rivet can hold the tensioning lever in the further swivel joint so that it can rotate or pivot and cannot be lost in the tensioning element.

The tensioning lever can be elongated and have a first free end in the tensioning lever or the longitudinal direction of the lever, which comprises a tensioning lever head with a tensioning lever mouth. A longitudinal axis of the tensioning lever can run parallel to the longitudinal axis of the ski binding, at least in a pivot position, possibly in a pivot position of the tension lever that can only be achieved theoretically. In other words, at least the stamped part or the cut part, which forms at least part of the clamping lever, can be aligned along the longitudinal axis of the ski binding and / or arranged parallel to the longitudinal axis of the ski binding, the stamped part or the cutting part preferably comprising or forming the clamping lever head with the clamping lever jaw.

The clamping lever mouth can be designed to be coupled to a mechanism of the front jaw or to intervene in this mechanism. A pivoting movement of the clamping lever can preferably be transmitted to the mechanism. The mechanism can be provided to tension the bearing arrangement of the toe piece, so that the ski boot is held in the bearing arrangement, and to relax it, in order to release the ski boot from the bearing arrangement.

The clamping lever can be formed solely by the at least one stamped part or the at least one cut part. Alternatively, the clamping lever can be constructed in a sandwich construction, the stamped part or the cut part being arranged between at least one first mold plate and at least one second mold plate, so that one of the mold plates forms a left outside and another of the mold plates forms a right outside of the clamping lever. The first mold plate and the second mold plate can be separate mold plates that are joined individually to the punched part or the cut 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 which at least partially engages around the stamped part or the cut part.

The first mold plate and the second mold plate, or the clamping lever housing, can be produced from a plastic, preferably in a plastic injection molding or deep-drawing process. They can be designed three-dimensionally, for example as a hollow body with a reinforcing structure, and have a printable surface so that they can be adapted to any design. The mold plates can also be made of a transparent or transparent material or plastic that can be printed on, for example, on its inside. Finally, the mold plates can have sections of different materials, for example they can be produced in a two-component or multi-component plastic injection molding process or they can comprise insert parts which are overmolded with plastic.

The first mold plate and the second mold plate are preferably joined to the punched part or to the cut part, preferably joined in a form-fitting and / or cohesive manner. Under Cohesive connection can be understood, for example, as the connection by means of an adhesive. An outer circumferential shape of the support surface of the first and second mold plate, which rests against the punched part or the cut part, can essentially correspond to the outer circumferential shape of the punched part or the cut part.

The positive and / or cohesive connection connects the stamped part or the cut part with the first mold plate and the second mold plate, preferably elastically, so that, for example, a temperature-dependent, different expansion between the stamped part or the cut part can be compensated for by the elastic connection. It is preferred if the material of the stamped part or the cut part and the material of the first and second mold plate, respectively the clamping lever housing, are 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 has a similar, preferably essentially the same, coefficient of linear expansion.

The first mold plate and the second mold plate preferably have a longitudinal extension that is smaller than a longitudinal extension of the stamped part or the cut part, so that the clamping lever jaw or a tongue of the clamping lever jaw at least partially over the first and second mold plate in the direction of the mechanism protrudes for tensioning and releasing the tensioning device.

The stamped part or the cut part is preferably connected to the clamping lever housing in a form-fitting manner. The stamped part or the cut part can in particular be connected to the clamping lever housing by means of one or more rivet connections and secured to the clamping lever housing. The rivet can be part of the first rotary joint and / or the second rotary joint. In addition, the stamped part or the cut part can be glued to the molded parts or the clamping lever housing. Alternatively, the clamping lever housing can be connected to the stamped part or the cut part via a screw body and / or by means of an adhesive. Finally, one of the stamped part or cut part and the clamping lever housing can comprise an engagement element which engages in a counter-engaging element of the other of the stamped part or cut part and the clamping lever housing. The counter-engagement element For example, there can be a slot or a through opening in the punched part or cut part, which is already produced during the punching or cutting, so that no further processing step is necessary. The counter-engagement element can, however, also be generated in a subsequent machining step. Correspondingly, the engagement element can be formed by the tensioning lever housing.

The tensioning element can be connected to the tensioning lever, preferably in a captive manner, in a swivel joint and can be pivoted relative to the tensioning lever in the swivel joint. In this case, the tensioning lever can lie within the tensioning element at least in a pivoted position with an end facing away from the tensioning lever head, that is to say, be at least partially surrounded by the tensioning element.

As already described, the tensioning lever can be connected to the base in a further swivel joint and can be pivoted relative to the base. The swivel joint, in which the clamping element is connected to the clamping lever, can be arranged after or behind the further swivel joint, that is to say closer to the tip of the ski, as seen in the longitudinal direction of the ski. The base can be suitable for being connected directly to a ski or to be connected to the ski via one or more intermediate elements.

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 rotary joint which connects the tensioning element to the tensioning lever. The contact surface serves, for example, as a stop for the contact device of the clamping element and limits the movement of the clamping lever in the latched position, that is to say when there is contact between the contact device and the contact surface. The bearing arrangement is locked by coupling the clamping lever to the bearing arrangement via a mechanism, so that a ski boot located in the toe piece cannot detach itself from the bearing arrangement even when a fall-triggering force is exerted. This condition is desirable and advantageous when climbing with a touring ski binding.

The stamped part or the cut part can have at least three clearly delimited sections: a first section which comprises a receptacle or an opening for a hinge axis of the swivel joint, which connects the clamping lever to the clamping element, a second section adjoining the first section, which can be designed so that it enables the required mobility of the clamping lever in the front jaw and / or can form a latch for the contact device in at least one pivot position of the contact device, and a third section adjoining the second section, which is a receptacle or an opening for the joint axis of the swivel joint, which preferably connects the stamped part or the cut part to the base, and comprises 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 or at least only partially covered by the mold plates or the clamping lever housing.

In other words, the first and / or the second mold plate or the tensioning lever housing can have at least three areas, a first area which includes a receptacle for the swivel joint, which connects the tensioning lever to the tensioning element, and a second area adjoining the first area , which is designed so that it can form a latch for the contact device in a pivoted position of the contact device, and a third area adjoining the second area, which has a receptacle for a swivel joint, which preferably connects the stamped part or the cut part to the base, includes. The punched part or the cut part can comprise a clamping lever head with a clamping lever mouth, and at least one tongue or part of the tongue of the clamping lever mouth can protrude in the longitudinal direction of the front jaw over one end of the first and second mold plates.

In the following, the subject matter of the application is explained further using an exemplary embodiment, without the invention being restricted to the exemplary embodiment shown. Technical features that are essential to the invention and can only be found in the figures are part of the scope of the disclosure and can advantageously develop the subject matter further. The figures show in detail:

The Figure 1 shows 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 front jaw 100 comprises a bearing arrangement 101 which, in the exemplary embodiment, consists of two pins which are provided for engaging in receptacles of a ski boot (not shown). In a first position, the bearing arrangement 101 or the pins firmly connect the toe piece 100 to the ski boot and form an axis which runs in a transverse direction Q to a longitudinal axis L of the toe piece 100. The ski boot can move around the axis from a first position in which the ski boot sole runs essentially parallel to an upper side of the ski and the heel section of the ski boot is approached to the ski, into a second position in which the ski boot sole forms an acute angle with the upper side of the ski, the heel section of the ski boot is removed from the ski, can be pivoted.

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 front jaw 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 in a swivel joint D1 connected with each other. The tensioning lever 20 is connected to the base 103 in a swivel joint D2. The tensioning lever 20 acts on a mechanism 102 which is connected to the bearing arrangement 101 or the pins, respectively, in order to move the latter 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.

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 a core that is punched or cut out of a plate material and is therefore also referred to as a punched part 21 or a cut part 21. In order to keep reading the description simple, only the stamped part 21 is mentioned below, with what has been said about the stamped part 21 also always applies to the cut part 21, unless expressly stated otherwise.

The stamped part 21 is preferably formed from a metal, for example from aluminum, steel, magnesium, another suitable metal or from an alloy which comprises at least one of the metals mentioned. The middle part can, however, also consist of more than one stamped part 21 which are joined together in order to form the middle part. If the middle 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.

Two mold plates 24, 25, which form a right and a left side of the clamping lever 20, are joined to the punched part 21. The mold plates 24, 25 can also be formed from metal, but they are preferably plastic parts that are produced, for example, in an injection molding, deep-drawing or other suitable manufacturing process. Polypropylene, polyethylene, polystyrene, PMMA, ABS or ASA / ABS, for example, can be used as suitable plastics without claiming to be exhaustive.

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 in order to save weight, which, for example, is introduced at the same time as the punching, since this does not require any additional expenditure of time , different from, for example, cutting. Breakthroughs elsewhere are conceivable and their suitability can easily be checked by a person skilled in the art through experiments.

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 knobs, etc., in order to prevent the shell from collapsing or pressing in when force is applied from the side. Finally, the mold plates 24, 25 can consist of different materials in some areas, for example of different plastics or partly of natural materials, such as compostable natural fibers, in order to have a further argument for the application.

The Figure 2 shows a section through the toe piece 100 along a ski binding longitudinal axis L. The stamped part 21 can be clearly seen. The punched part 21 has an opening or a receptacle 52 which is part of the swivel joint D1 or at least receives the swivel joint D1, in which the clamping element 10 can be connected to the clamping lever 20 in a rotatable manner. Furthermore, an opening or a recess 53 is formed in the stamped part 21, which forms part of the swivel joint D2 or at least receives the swivel joint D2, in which the clamping lever 20 can be rotatably connected to the base 103.

At its end facing the mechanism 102, the punched part 21 comprises 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 2 the clamping 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 are pressed into recesses in the ski boot sole.

The clamping element 10 comprises a contact device 11 which interacts with a contact surface 104 and forms a support and securing 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 it can be molded in one piece with the base 103. The tensioning lever 20 has a central region on its side facing the ski, as seen in the longitudinal direction HL of the lever a recess 28 which, in a pivoted position of the clamping element 10, forms a latch for the contact device 11 and thus also for the clamping element 10. The recess 28 can also only be due to the structure of the front jaw and enable the required mobility of the clamping lever 20 in the front jaw.
