Description

Technical area

The present invention relates to a toe device for touring ski binding, comprising a buttock element, wherein the buttock element comprises a receiving tray for receiving the heel part of a ski boot and a biasing device for biasing the buttock device against a ski boot, and wherein the buttock device between a starting position for receiving or releasing the ski boot and a latching position for holding the ski boot is switchable.

State of the art

Ski bindings for touring skis are characterized in the first line by the fact that they can be switched in comparison to ordinary ski bindings between a climb mode and a downhill mode. In the ascent mode, only the front area of the ski boot is fixed on the ski, so that the rear area of the ski boot can be lifted off the ski and deposited thereon. The front area of the ski boot rotates about a horizontal, perpendicular to the ski longitudinal axis pronounced. In downhill mode, both the front and rear sections of the ski boot are firmly fixed to the ski.

The conventional touring binding systems can be divided into web binding systems and pin systems. In the pin systems, the bonds can be divided into a toe device and a buttock device. In the ascent mode, the ski boot is only rotatably supported by the toe device about a horizontal, perpendicular to the longitudinal direction of the ski pivot axis.

Touring binding systems usually have one or more climbing aids, by means of which it is possible to increase the walking comfort in steep terrain. The heel part of a ski boot can be used in ascent mode instead of on the ski surface, or a ski boot Base plate to be dropped on the climbing aid, resulting in a less steep stand and correspondingly more comfortable.

For example, shows DE 10 2012 206 879 A1 a lightweight ski binding with increased trigger safety. DE 10 2010 006 218 A1 concerns a ski binding with climbing aid. EP 0 199 098 A2 shows a touring ski binding. The EP 2 695 647 A1 describes a ski brake with lock. From the EP 2 762 209 A2 is a heel holder with auxiliary lever known.
The DE 10 2013 204065 A1 shows a buttock with a ski brake for a ski touring binding.

The activation and deactivation of the known from the prior art different climbing aids designed in the rule, however, quite expensive, since several handles are necessary. In changeable terrain, the constant activation and deactivation of the climbing aid proves to be extremely tedious. Often it is also necessary to lift the ski boot from the climbing aid in order to disable the climbing aid can. These necessary actions can be uncomfortable, especially on steep terrain.

Presentation of the invention

Starting from the known prior art, it is an object of the present invention to provide an improved buttock device, which allows easy activation and deactivation of a climbing aid.

This object is achieved by means of a device having the features of claim 1. Advantageous embodiments emerge from the subclaims.

Accordingly, there is provided a toe binding device for touring ski binding comprising a buttock member, the buttock member comprising a receiving tray for receiving the heel portion of a ski boot and a biasing apparatus for biasing the buttock apparatus against a ski boot, and wherein the buttock apparatus is disposed between a home position for receiving or releasing the ski boot and a latching position for holding the ski boot is switchable. According to the invention, the rear jaw device comprises a means for blocking, by means of which the buttock device can be locked in the starting position, wherein the means for blocking between a blocking position and a non-blocking position is switchable.

This makes it possible to prevent the buttock device from being set in the latching position. As a result, the heel part of a ski boot can be raised or lowered by the butt-end device, in particular by the receiving shell. The receiving tray serves as a climbing aid in this position. A ski boot rotatably mounted on a toe jaw about a horizontal transverse axis may be used in a climb function.

Accordingly, the means for blocking in the blocking position forms together with the buttock member a climbing aid, on which the heel part of a ski boot can be lowered. There are no additional components needed to provide a climbing aid for climbing in steep terrain. The buttock element and in particular the receiving shell are adapted to the geometry of the ski boot and can thus provide an ideal support function.

The fact that the buttock element is blocked in the starting position, a quick and convenient switching to the locking position is possible. If the blocking means is brought into the non-blocking position, the buttock element can yield to the pressure of a ski boot and assume the latching position. A lifting of the heel part of the ski boot is not required. Rather, the binding can switch directly from the provision of a climbing aid in the locking position.

Further, it is possible to provide the buttock device with a conventional buttock element. That is, it is possible to use a buttock member of a downhill binding for touring ski binding. With the blocking means in the non-blocking position, the buttock element, and thus the buttock device, can assume the latching position in which the ski boot is held on the ski. The means for blocking in the blocking position prevents a vertical downward movement of the buttock element, so that it can be held in its initial position. If the heel part of the ski boot is now lowered onto the buttock element, the buttock element retains its starting position, so that the heel part of the ski boot does not latch into the buttock device.

In a preferred embodiment, the means for blocking is slidably disposed relative to the buttock element. This makes it possible for the means to block to shift by a sliding movement between the blocking position and the non-blocking position.

In a development, the means for blocking is arranged on a base plate, wherein the base plate can be arranged on a ski surface. Conventional buttocks devices usually already have a base plate. Accordingly, it is sufficient to arrange the means for blocking on a conventional base plate, or to integrate into a conventional base plate. The base plate represents the interface of the buttock device to the ski.

In a further preferred development, the base plate and the means for blocking via a slot guide are slidably coupled relative to each other. The groove defines the displacement of the means for blocking relative to the base plate. In this case, the groove may be arranged in the means for blocking or in the base plate. When the groove is disposed in the means for blocking, the base plate has a complementary guide, for example a rail, which engages the groove. If the groove is arranged in the base plate, then the means for blocking the guide. The length of the groove guide allows the shifting of the means for blocking between the blocking position and the non-blocking position. The groove guide also allows a positionally accurate arranging or moving the means for blocking on the base plate.

A groove of the groove guide, which runs, for example, on the surface of the means for blocking, may have inclined walls, so that provided from the surface of the means for blocking from an undercut is provided. By a correspondingly complementary to this groove running guide on top of the base plate, the base plate can be securely held in the groove.

The groove may be made to completely pass through the blocking means, that is, the ends of the groove are open. In this way it is possible, by means of the guide in the groove residues, such as snow, push out of the groove.

In a further preferred development, the rear jaw device comprises means for latching in order to hold the means for blocking in the blocking position and / or the non-blocking position. This will prevent the agent from blocking during use the buttock device automatically releases from the blocking position or the non-blocking position. The latching means may be provided, for example, by a biased bracket on the guide of the blocking means, which interacts with a projection in a groove of a base plate in which the means for blocking is guided. At the level of the forms, the groove has a greater width, whereby the biased bow of the blocking agent can expand. In order to transfer the guidance of the means for blocking from the wide area, that is the area of the expression, of the groove into the narrower area of the groove, a manual intervention of the user is necessary.

In a further preferred embodiment, the means for blocking in the longitudinal direction of the ski is displaceable. In the ski longitudinal direction, sufficient space is provided to push the blocking means out of the range of motion of the buttock element. For example, the non-blocking position may be defined in an area behind the buttock member, such that the longitudinal-locking means is displaced behind the buttock member to allow engagement of the butt-cheek apparatus.

In a further preferred embodiment, the means for blocking in the blocking position can be positioned below the buttock element. Thereby, it is possible to suppress a vertical movement, that is, a downward movement, of the buttock member when a force pushes the buttock member downwards, that is, towards the ski surface. Such a force can originate, for example, from the heel part of a ski boot. If a touring ski binding is in the ascent position, in which a toe shoe rotatably supports the ski boot about the horizontal transverse axis, the heel part of the ski boot can be set down on the rear shoe element without the rear shoe element assuming the engagement position. Rather, the means for blocking, by positioning it below the buttock element, ensures that the buttock device is held in the home position.

According to the invention, the receiving cup comprises a flange, wherein the flange in the initial position of the buttock device is contactable with a ski boot, and wherein the flange rests in the blocking position on the means for blocking. In the non-blocking position, the flange is entrained by a downward movement of the heel part of the ski boot, thus triggering the engagement of the locking position. In the blocking position of the buttock device, the flange can serve as a climbing aid onto which the heel part of the ski boot is lowered or lifted by which the heel part of the ski boot can be when the touring ski binding is in the ascent position. Accordingly, no additional components are needed to provide a climbing aid for the ascent function of touring ski binding.

In a further preferred embodiment, the means for blocking on at least one holding element for holding down a stopper plate. This makes it possible that when the touring ski binding is in the ascent mode, the ski brake is not triggered. The stopper plate is biased by a torsion spring against the surface of the ski. From the stopper plate extend two arms which extend in the downhill mode almost parallel to the ski longitudinal direction. In the process, a ski boot clamped in the binding holds the stopper plate against the spring force on the surface of the ski. When the ski boot is released, the spring pushes the stopper plate away from the ski surface, thereby changing the orientation of the arms. The arms are down in this condition and protrude beyond the surface of the skis. In this way, a loose ski can be braked.

In the ascent mode of touring ski binding, the stopper plate is not contacted by the ski boot, so that the stopper plate is pressed together with the arms of the spring in the braking position. To prevent this, in the blocking position, the retaining elements of the blocking means are at least partially pushed over the stopper plate, so that the stopper plate is held on the ski surface and the braking function is not triggered, even if there is no ski boot on the stopper plate.

Detailed description of preferred embodiments

In the following, preferred embodiments will be described with reference to the figures. In this case, identical, similar or identically acting elements are denoted by identical reference numerals. In order to avoid redundancy, a repeated description of these elements will be omitted in the following description.

FIG. 1 shows a perspective view of a buttock device 1. The buttock device 1 comprises a base plate 30 which can be mounted on the surface of a ski. As a rule, the base plate 30 is screwed onto the surface of the ski. Alternatively, the base plate 30 may also be adhered to the surface of the ski.

On the base plate 30 by means of two brackets 18, a buttock element 10 is attached. The buttock element 10 serves to receive the heel part of a ski boot and to bias the ski boot against a toe-jaw device. Accordingly, the buttock element 10 comprises a receiving tray 12, which is adapted to receive the heel part of a ski boot. In the FIG. 1 illustrated butt device 1 is located in the Starting position in which the buttock element 10 is ready to receive the heel part of the ski boot.

At a lower edge of the receiving tray 12, a flange 16 is arranged, on which the heel part of the ski boot can be discontinued. A ski boot which is deposited on the flange 16, by a further downward movement, the butt cheek device 1 in the in FIG. 3 Transfer shown latching position. In this position, the ski boot is engaged in the touring ski binding, with the buttock element 10 biasing the ski boot against the toe device. The touring ski binding is then in downhill mode.

The buttock device 1 further comprises a blocking means 20, which is arranged on the base plate 30. The means for blocking 20 may be between the in FIG. 1 shown non-blocking position and the in FIG. 2 be moved shown blocking position. The displacement of the means for blocking 20 takes place in the ski longitudinal direction L. In the in FIG. 1 In the non-blocking position shown, the means for blocking 20 is inactive so that the butt-end device 1 can be moved away from the in-shoe device by receiving the heel part of a ski boot FIG. 1 shown starting position in the in FIG. 3 shown latching position can be transferred.

FIG. 2A shows the buttock device 1 from FIG. 1 with the difference that the means for blocking 20 is in the blocking position. The blocking means 20 is closer to the stopper plate 40 than the non-blocking position so as to be located immediately below the flange 16 of the buttock element 10. In this case, the flange 16 rests on a surface 24 of the means for blocking 20. The means for blocking 20 thereby prevents the flange 16 from moving toward the base plate 30 when a force acts on the flange 16, for example from the heel portion of a ski boot. Accordingly, the blocking means 20 in the blocking position prevents the buttock device from being transferred to the locking position. Consequently, a ski boot on the flange 16 can be discontinued without the buttock device 1 and thus the touring ski binding snaps.

The FIGS. 1 . 2A and 2 B further show a stopper plate 40, which is arranged in the front region of the base plate 30. The stopper plate 40 is biased by a torsion spring against the base plate 30. As FIG. 1 can be seen extending two stopper arms 42 almost perpendicular to the ski longitudinal direction L, when the stopper plate 40 unhindered by the spring force of the base plate 30 is pushed away. When a force is applied to the stopper plate 40 so that the stopper plate 40 is pressed onto the base plate, the coupling between the stopper plate 40 and the stopper arms 42 causes the stopper arms 42 to be nearly parallel to the longitudinal direction of the ski.

The FIGS. 1 , and 2A It can also be seen that the means for blocking comprises 20 holding elements 26. If the blocking means is in the blocking position, as in FIG FIG. 2 shown, the holding elements 26 are partially pushed over the stopper plate 40, and hold them against the force acting on the stopper plate spring force on the base plate 30. Accordingly, the holding elements 26 in the in FIG. 2 shown blocking position of the blocking means 20 that the stopper arms 42 are aligned almost parallel to the ski longitudinal direction L without a ski boot is on the stopper plate 40.

Is the blocking means 20 in the in the FIGS. 2A and 2 B shown blocking position, the receiving tray 12 can be charged together with the flange 16, wherein the buttock device 1 maintains the starting position. Thereby, the heel part of a ski boot can be lowered onto the flange 16 and lifted by the flange 16, so that the flange 16 serves as a climbing aid when the touring ski binding is in the ascent mode.

FIG. 2B shows a side view of the Hinterbackenvorrichung FIG. 2A , It can be clearly seen that the flange 16 of the buttock element 10 rests on the means 20 for blocking. As a result, the flange 16 provides a climbing aid to which the heel portion of a ski boot can be lowered and lifted therefrom. The climbing aid increases walking comfort in steep terrain.

FIG. 3 shows a perspective view of the Hinterbackenvorrichung 1 from FIG. 1 , The buttock device 1 assumes this position when the heel part of a ski boot is biased against the base plate 30. That is, the touring ski binding is in downhill mode, with a ski boot is firmly clamped in the touring ski binding. FIG. 3 shows the means for blocking 20 in a non-blocking position.

The stopper plate 40 is held in the adjacent position by the sole of a ski boot clamped in the touring ski binding. If the ski boot, for example, by a fall, out releases the binding, the stopper plate 40 can assume a protruding position because it is not blocked by the blocking means 20. As a result, the stopper arms 42 are moved in the direction of the road surface, so that the lost ski can be braked.

FIG. 4A shows the section BB FIG. 4B by a detailed view of a means for blocking 20 and a base plate 30. The means for blocking 20 can be moved in the longitudinal direction L. In this case, the means for blocking 20 has a groove 28 by means of which it can slide on a guide 32 of the base plate 30. Alternatively, the groove may also be arranged in the base plate and the guide in the means for blocking.

FIG. 4B shows the section AA FIG. 4A , The lateral walls of the groove 28 have seen from the base plate 30 from undercuts. The base plate includes a guide 32 complementary to the profile of the groove 28, which ensures that the blocking means 20 is retained on the base plate 30.

FIG. 5A shows the section DD FIG. 5B by a detailed view of a blocking means 20 and a base plate 30. FIG. 5B shows the section CC FIG. 5A , The means for locking 20 comprises a means for latching 22. The means for latching 22 comprises a bore on a base plate 30 facing surface of the blocking means 20. The means for latching 22 further comprises a spring-biased ball 23, which in the bore is arranged. The spring biases the ball 23 against the base plate 30.

The base plate 30 has forms 34, 35, in which the ball 23 can be pressed by means of the spring. The FIGS. 5A and 5B show the means for blocking 20 in a non-locked position. Latches the ball 23 in the expression 34, there is the means for blocking in the non-blocking position. Latches the ball 23 as in FIG. 5C shown in the expression 35, there is the means for blocking in the blocking position. The spring force defines the force needed to release the blocking means 20 from a locked position.

The individual components of the touring binding system are made of plastic and / or metal. In the plastic components, among other things, injection molded components are used. There are preferably lightweight materials used, which is why in particular fiber-reinforced plastics and / or aluminum are installed.

Where applicable, all individual features illustrated in the individual embodiments may be combined and / or interchanged without departing from the scope of the invention as defined by the appended claims.
