Description

The invention relates to a cross-country or touring ski binding for the articulated connection of a boot with a ski, with a binding base body which has a contact surface for a sole of the boot and a ski support surface for at least indirect support on the ski, with a holding device which has a receptacle for pivoting Arrangement of the shoe about a pivot axis running in the transverse direction of the binding base body and a holding element for holding the shoe on the receptacle, the holding element being displaceably mounted on the binding base body between a closed position holding the shoe on the receptacle and an open position releasing the shoe, with a Actuating element which has a rotary handle for transferring the holding element from the closed to the open position, the axis of rotation of which runs essentially perpendicular to the contact surface of the binding base body.

Such a ski binding is available from the applicant under the product name “Turnamic”. In the case of ski bindings of this type, it is known that the twist grip and the binding base body have interacting latching elements so that the twist grip is held in a latching manner in the closed position.

Another ski binding with a rotary handle for transferring the holding element from the closed to the open position with an axis of rotation that runs essentially perpendicular to the contact surface of the binding body is shown in FIG DE 9422308 U1 known. In this binding, the rotary handle or the holding element is not even held in a latching manner in the closed position.

From the FR 2526322 A1 Furthermore, a cross-country ski binding is known in which a sole projection can be connected to the cross-country ski binding with the aid of a pivotably mounted cam which has a lever element. To secure the cam in its holding position, the elastically deformable tongue element is provided, which in the holding position engages behind a cam projection with its front tongue section, so that - if no force is applied to the elastic tongue element in the area of the receptacle - held in its holding position will. EP 1 721 641 A1 discloses an adjusting device for a spring element of a restoring device, with which one end of the spring element can be arranged in two different positions, whereby the preload of the spring element can be adjusted. The connecting arm, on which one end of the spring element is arranged, can accordingly be brought into an advanced position via a control element, in which the arm strikes a lateral nose.

From the US 9,022,411 B2 a cross-country or touring ski binding with a base part for a rotary locking mechanism is known. The base part has a flat support section and one or more support sections which protrude from the plane of the flat support section. The support sections each have a shaft pin hole for receiving an axis of a part connected to the rotary locking mechanism. The rotary locking mechanism has an actuating element which is rotatably connected to the base part about an axis arranged parallel to the support section. Such widespread cross-country ski bindings thus have a pivot lever for opening or closing the binding, the pivot axis running essentially parallel to a fastening axis running on the shoe to be connected. In such ski bindings, too, it is already known to provide a latching projection which is designed to receive a front end of the pivot lever when the pivot lever is in the locked position.

Since in ski bindings of this type with a pivot axis arranged parallel to the contact surface, the pivot lever must be moved upwards against gravity into the open position, a locking connection is a connection which is easily released when a (low) elastic restoring force of a locking element is overcome can be sufficient to secure the pivot lever in such ski bindings.

A completely different situation is given with cross-country or touring ski bindings of the type mentioned at the outset, in which the rotary handle for transferring the holding element from the closed to the open position is not pivoted upwards at its free end, against gravity, but to open the binding the twist grip only has to be swiveled out to the side. Although this is extremely advantageous in terms of the handle for opening and closing the ski binding, it does, however, involve an increased risk that the twist grip is twisted inadvertently during use; ie around the perpendicular to the contact area The axis of rotation is pivoted laterally, so that the ski binding is opened inadvertently. So far it was only known in such ski bindings - as already mentioned above - to provide locking elements for fixing the position of the rotary handle in the closed position.

Due to the increased risk of unintentional opening of the ski binding, the object of the invention is to create a locking of the rotary handle in the closed position of the ski binding that goes beyond simply securing the rotary handle by means of a snap connection.

According to the invention, this is achieved in that a locking element that can be transferred between a locking position and a release position is provided, the rotary handle being held in the locking position in a non-rotatable manner relative to the binding body in a form-fitting manner, the locking element being designed in such a way that it cannot be removed from the form-fitting by means of elastic deformation Connection can be released, and the rotary handle is released in the release position for a pivoting movement about its axis of rotation.

By providing a positive connection in the locking position, the rotary handle is reliably secured against unintentional rotation in the use position of the ski binding. In the context of the invention, a form-fitting connection is accordingly understood to mean a connection in which - unlike known latching connections - the rotary handle cannot be released in a simple manner by elastic deformation of the locking element. In particular, the locking element is accordingly designed in such a way that the user cannot elastically deform it when operating the rotary handle, which is usually one-handed, ie cannot detach it from the form-fitting connection by means of an elastic deformation. Accordingly, a separate actuation of the locking element is first required, with which the user transfers the locking element from the locking position to its release position without moving or pivoting the rotary handle before the rotary handle is released for a pivoting movement about its axis of rotation.

With regard to user-friendly operability when locking or unlocking the rotary handle, it is advantageous if the locking element is mounted on the rotary handle or the binding body for transferring between the release position and the locking position. With the aid of the mounting of the locking element on the rotary handle, the locking element can be easily grasped by the user. In addition, the storage on the rotary handle also provides a reliable connection between the locking element and the rotary handle, so that only the locking element or a section of the locking element has to be brought into engagement with the element of the ski binding when the rotary handle is in the locked position.

A rotationally fixed arrangement of the rotary handle in the locking position is achieved in a particularly simple and reliable manner if, in the locking position, the locking element is positively connected to a binding base body in such a way that the rotary handle is non-rotatably connected to the binding base body via the locking element. To establish the locking position, it is therefore only necessary that a section of the locking element comes into positive engagement with the binding base body, so that a twisting of the rotary handle is reliably prevented.

Such a form-fitting connection can be achieved in a particularly simple manner in that, in the locking position, the locking element is positively connected to the binding base body in such a way that the rotary handle is non-rotatably connected to the binding base body. By means of the form-fitting connection between the locking element and the binding base body, the rotary handle on which the locking element is mounted is thus fixed in a rotationally fixed manner on the binding base body in a simple manner. In this position, the twist grip cannot be unintentionally released from the closed position, so that unintentional opening of the binding - as is quite possible in the case of a mere snap-in connection to secure the closed position when the appropriate force is applied - is reliably prevented.

A structurally simple embodiment for the positive connection between the locking element and the binding body is achieved if the locking element has a projection which, in the locking position, is received in a receiving opening in the binding body. By receiving the projection of the locking element in a receiving opening formed in the binding base body, it is therefore only necessary to move the locking element in order to transfer between the locking position and the release position in such a way that the projection is either received in the receiving opening or - if a release is desired - is removed from the receiving opening. The same essentially applies to the alternative configuration of a bearing on the binding body. If the locking element is in engagement with the rotary handle in the locking position, the rotary handle is reliably secured against rotation by the connection to the binding base body via the locking element.

In order to prevent an unintentional release of the locking element from the locking position, it is also advantageous if the locking element is secured in the locking position and / or the release position via a latching connection. With the aid of a latching connection, the locking element can thus be secured in its locking position and / or the release position in a simple manner. However, even if this locking connection is released from the locking position, this does not automatically lead to the transfer of the locking element into the release position. Accordingly, even in the event of an unintentional release of the latching connection of the locking element, the locking element can in principle still be arranged in its locking position.

With regard to simple operability when transferring the locking element between the locking and release positions, it is advantageous if the locking element is pivotably mounted between the locking position and the release position, the locking element in the locking position preferably being at least partially in a recess is received within the twist grip. With the help of the pivotable mounting of the locking element on the rotary handle, this can thus be easily grasped by the user from above and from a locking position pivoted downwards in the direction of the contact surface, in which the rotary handle is hardly accessible to the user, preferably due to its inclusion within the recess in the rotary handle is perceptible, be transferred into an upwardly pivoted release position.

For particularly simple operation and structurally simple mounting of the locking element in or on the rotary handle, it is advantageous if the locking element is pivotably connected to the rotary handle in a front end section and has the projection in a rear end section directed towards the holding element, which in the locking position in a receiving opening of the binding body is received.

As an alternative to the above-mentioned pivotable mounting of the locking element on the twist grip, it is also conceivable that the locking element is displaceably mounted in a recess in the twist grip or in the binding base body between the locking position and the release position. The locking element can also be transferred from the locking position into the release position in a simple manner with a sliding movement.

A high level of operating convenience can be achieved here if the locking element is mounted so as to be positively displaceable between the locking position and the release position essentially perpendicular to the contact surface. In this embodiment, the user can thus easily pull on the locking element, so that the latter is transferred from a locking position that has been shifted downward into an upwardly shifted release position.

A substantially linear displaceability of the locking element is achieved in a structurally simple manner in that the locking element preferably has an elastic expandable pocket at at least one end in which a pocket extending longitudinally essentially perpendicular to the contact surface Web is added, the longitudinal extent of the pocket is greater than the longitudinal extent of the web. Due to the design of the expandable pocket, when the locking element is first inserted in the ski binding, i.e. when the individual binding parts are joined together, it can be easily inserted into the recess in the rotary handle so that the locking element is then guided in a longitudinally displaceable manner via the sliding interaction of the web and pocket .

In a further alternative embodiment it is provided that the locking element is not movably mounted perpendicular to the contact surface, but the locking element is mounted forcibly displaceable between the locking position and the release position essentially parallel or perpendicular to the contact surface.

For a structurally simple guidance of the locking element in the direction of the contact surface, the rotary handle can have a guide recess, the longitudinal extent of which extends essentially parallel to the contact surface, the locking element having a web extending essentially parallel to the contact surface, which is at least partially received in the guide recess .

In order to secure the displaceably mounted locking element in its locking position, it is advantageous if the locking element has at least one locking element on the side which, in a secured locking position, interacts with a locking element provided on a side wall of the recess of the rotary handle or the binding base body.

In this case, the recess can have inwardly projecting guide webs in cross section perpendicular to the direction of displacement, which guide webs are received in corresponding guide grooves of the locking part. A positive guidance of the locking element is thus achieved in a simple, constructive manner.

The displaceability of the locking element in the direction of the contact surface can be achieved in a simple manner in that the longitudinal extension of the projection is essentially parallel to the Contact area runs. For a positive connection between the locking element and the binding base body carrying the twist grip, it is advantageous in this embodiment if the receiving opening is provided in a wall of the binding base body that is essentially perpendicular to the contact surface.

In Fig. 1 is a cross-country or touring ski binding 1 for the articulated connection of a boot (not shown) with a ski 2 (cf. Fig. 3 and 4th ) shown. The binding 1 has a binding base body 4, which has a contact surface 5a for a sole of the boot and a ski support surface 5b for at least indirect support on the ski 2.

The ski binding 1 comprises a holding device 7, which has a receptacle 8 for the swivelable arrangement of a swivel axis of the boot running in the transverse direction of the binding base body 4 and a holding element 9 for holding the swivel axis of the boot in the receptacle 8. The holding element 9 is between a closed position holding the shoe on the receptacle 8 (cf. Fig. 3a , 3b and 4a , 4b ) and an open position releasing the shoe, mounted displaceably on the binding base body 4 (cf. Fig. 5 ).

With an actuating element 13, which has a rotary handle 14, the holding element 9 can be transferred from the closed to the open position. An axis of rotation 15 of the rotary handle 14 runs essentially perpendicular to the contact surface 5a of the binding base body 4 and is received in an opening 15a of the binding base body 15.

In addition, a locking element 16 which can be transferred between a locking position and a release position can be seen. In the first exemplary embodiment, the locking element 16 is rotatably connected to the rotary handle 14 via pivot axes 17. For a compact, inconspicuous arrangement of the locking element 16, in particular in the locking position, the rotary handle 14 has a central recess or recess 18 in which the locking element 16 is received in the locking position, preferably almost entirely. In the locking position of the locking element 16, the rotary handle 14 is held non-rotatable with respect to the binding body 4, the locking element 16 being supported on or in the rotary handle 14 so that it can be transferred between the locking position and a release position.

As in Fig. 3a and 3b As can be seen, in the locking position the locking element 16 is positively connected to the binding base body 4 in such a way that the rotary handle 14 is connected non-rotatably to the binding base body 4. For this purpose, the locking element 16 has a projection 16a which in the locking position in a receiving opening 19 (cf. Fig. 2 ) of the binding body 4 is added.

In order to transfer from the locking position to the release position, the locking element 16 is mounted pivotably via the pivot axes 17. As in Figure 4a As can be seen, when the locking element 16 is pivoted, the projection 16a is moved in the direction of the arrow 22 and thus out of the receiving opening 19 (cf. Fig. 2 ) moved so that the rotary handle 14 for a rotary movement is released about the axis 15.

The locking element is secured in the locking position via a latching connection. For this purpose, a latching element 20a is provided on the locking element 16 on the rear side, i.e. facing in the direction of the shoe receptacle, and a latching element 20b is provided on a front side of a wall 21 of the ski binding 1 which is arranged essentially perpendicular to the contact surface 5a. The locking element 20b is preferably of raised and elastic design and, in the locking position, engages in the locking element 20a, designed as a corresponding recess, for securing the rotary handle 14 in the closed position. As an alternative or in addition to the latching element 20a, the locking element 16 can also have a further latching element, preferably designed as a notch 20c. The locking element 16 here preferably has a recess 17a on the underside, so that the locking element 16 essentially has the shape of an inverted U in a side view. On the rear leg of this U in a forward-facing wall, the notch 20c is then preferably formed, which engages with a corresponding projection on the binding body side (not shown) in the locking position of the locking element 16 to secure it in the locking position.

In Figure 3c an alternative embodiment of the locking element 16 of the first embodiment is shown, which has an additional notch 17b. The notch 17b extends upwards from an underside of the locking element, in particular perpendicular to the contact surface 5a, so that the locking element has reduced rigidity in this area and the locking element 16 thus has increased flexibility in the area of the notch 17b. Thus, the distance between the pivot axis 17 and the latching element 28 - for example due to different shrinkage values of the locking element 16 and the binding base body 4 - vary. With the help of the notch 17b, which increases the flexibility of the locking element 16, smooth locking and unlocking is ensured.

In the Figures 6 to 8 and the Figures 9 to 12 Two further exemplary embodiments are shown in which the locking element 16 in the recess 18 in the rotary handle 14 between the locking position and the release position is slidably mounted.

In the second embodiment according to the Figures 6 to 8 the locking element 16 is mounted so that it can be displaced between the locking position and the release position in the displacement direction 22a, essentially perpendicular to the contact surface 5a. For this purpose, the locking element 16 has a pocket 23 which is delimited by two lateral wall elements 24a, 24b, at least one of the two wall elements 24a, 24b having a latching hook 25 at its freely protruding end and being elastically deformable. In this way, under the elastic deformation, the locking element 16 can be pushed into the recess 18 in at least one of the two wall elements 24a, 24b. In this case, with elastic deformation, at least one of the two wall elements 24a, 24b and a web 26 of the rotary handle 14 extending essentially perpendicularly to the contact surface 5a are encompassed. In the relaxed state of the two wall elements 24a, 24b, the locking element 16 is guided essentially in the linear direction 22a by receiving the web 26 in the pocket 23, so that the locking element 16 is easily moved from a lower locking position in the direction of the contact surface 5a ( Fig. 8 ) in an upwardly shifted release position ( Fig. 7 ) can be transferred in the displacement direction 22a.

In order to define the displacement path of the locking element 16, the longitudinal extent of the pocket 23 is greater than the longitudinal extent of the web 26. As in FIG Fig. 7 As can be seen, in the upwardly displaced release position of the locking element 16, a lower end 26a of the web 26 strikes the latching hook 25 of the wall elements 24a, 24b delimiting the pocket, so that it is clear to the user that he has reached the release position. In addition, a latching projection 27 engages in the upper release position above a locking projection 28 on the rotating handle side, so that the locking element is held in the release position via the latching connection.

In Fig. 8 the locking element 16 is shown in its downwardly displaced locking position, in which a large part of the locking element 16 is received in the recess 18 in the rotary handle 14. As in Fig. 8 As can be seen, the lower locking position is defined on the one hand by the abutment of a lower surface 29a of an upper handle part 29, which rests on lateral walls 30 of the rotary handle 14, which laterally enclose the recess 18. In addition, the latching projection 28 latches in a correspondingly designed latching recess 31 on an elastically pivotable wall element 32 of the locking element 16. It can also be seen that the projection 16a of the locking element 16 thus projects downwards and thus in the locking position in a recess 19 correspondingly arranged in the binding base body 4 is recorded positively. In this position of the projection 16a received in the recess 19, rotation of the rotary handle 14 about its pivot axis 15 is therefore impossible, so that inadvertent opening of the holding elements 9 is reliably prevented.

In the third embodiment according to FIGS Figures 9 to 12 the locking element is mounted between the locking position and the release position in the displacement direction 22b, essentially parallel to the contact surface 5a, forcibly displaceable. For this purpose, the rotary handle 14 has a guide recess 33, the longitudinal extent of which extends essentially parallel to the contact surface 5a. The locking element 16 has a web 34 which extends essentially parallel to the contact surface 5a and which is at least partially received in the guide recess. With regard to simple operability, the locking element 16 has an upper projection 34a designed as a handle, via which the locking element 16 can be moved in a simple manner in the displacement direction 22b.

In order to guide the locking element essentially in the displacement direction 22b, the recess 18 has a cross section perpendicular to the displacement direction 22b (cf. Fig. 11 ) inwardly projecting guide webs 35, which are received in corresponding guide grooves 36 of the locking element 16.

To the locking element 16 in the locking position and to be locked in the release position, locking projections 38 are provided on the side walls, which interact with two locking recesses 39, which are offset from one another in the displacement direction 22b and which are each provided on a side wall of the recess 18 of the rotary handle 14. Of course, a reverse arrangement of the latching projections / recesses on the locking element 16 and the rotary handle 14 is also possible.

As in the in the Figures 10 and 12 The locking position of the locking element 16 shown in the figure, thus protrudes in the locking position with respect to the rear side of the walls 30 delimiting the recess 18 and can thus engage in the receiving opening 19 on the binding side.

Since the longitudinal extension of the projection 16a in this embodiment runs essentially parallel to the contact surface 5a, it is expedient if the receiving opening 19 in this embodiment is provided in a wall 21 of the binding base body 4 (not shown) that is essentially perpendicular to the contact surface 5a.

In Figures 13a, 13b and 14a, 14b Another exemplary embodiment is shown in which the locking element 16 is mounted in a front end region of the binding base body 4 so as to be pivotable about a pivot axis 41. For the formation of the pivot axis 41, the locking element has two laterally projecting axle stubs 42 which are arranged on resilient webs 43 at the ends. By means of elastic deformation of the resilient webs 43, the two axle stubs 42 can be brought closer to one another and received in corresponding receiving openings in the binding base body 4. The end of the locking element 16 opposite to the pivot axis 41 has a transverse handle 44 via which the user can easily grasp the locking element 16 and between the in Figures 13a and 13b Approval position shown and the in Figures 14a, 14b can pivot locking position shown. In the in Figures 14a, 14b Locking position shown, it can be seen that locking element 16 in sections in the Recess 18a is received in the rotary handle 14, which is laterally bounded by walls 18b. By arranging the locking element 16 in the recess 18a, the rotary handle 14 is thus locked against pivoting.

To secure the locking element 16 both in the release and in the locking position, the locking element 16 has lateral projections 45 on the resilient webs 43 (cf. Figures 15a, 15b ), which snap into corresponding recesses 46a, 46b on the binding base body 4 in the release or on the rotary handle 14 in the locking position and thus secure the locking element 16 in the respective position.

In the Figures 16 and 17 and FIGS. 18a, 18b show a fifth exemplary embodiment in which the locking element 16 is mounted in the front end region of the basic binding body 4, as in the previous exemplary embodiment. In contrast to the previous exemplary embodiment, however, in this exemplary embodiment the locking element 16 is mounted displaceably in the binding base body 4. As in Fig. 16 As shown, the basic binding body 4 has a recess 46a in which the locking element 16 is displaceably mounted. In the position shifted downwards in the direction of arrow 47, the upper end of the locking element 16 does not protrude into a recess 46b on the rotary handle side, so that the rotary handle 14 is supported in an unhindered manner. However, if - as in Fig. 17 shown - the locking element 16 is shifted upward in the direction of arrow 48, the locking element 16 engages with its upper end portion in the recess 46b in the rotary handle 14, so that a rotation of the rotary handle 14 is prevented.

In order to secure the locking element 16 again in the release and the locking position, the locking element 16 in this embodiment has notches 49 in spring-mounted webs which interact with corresponding projections in the recess 46a both in the release position and in the locking position.

For easy operation of the locking element 16 according to Figures 16, 17, 18a and 18b the locking element 16 has a handle part 50 which can be operated by hand without an additional tool in order to move the locking element in the direction of the arrows 47 and 48, respectively.

In the 19, 20 and FIGS. 21a to 21c show a further, sixth exemplary embodiment. In this case, a locking element 16 is provided, which is mounted on the binding base body so as to be displaceable essentially perpendicular to the contact surface 5a. In a release position shifted downward in the direction of arrow 47 (cf. Fig. 19 ) is the rotary handle 14 for pivoting from the in Fig. 19 position shown released.

However, if the locking element 16 - as in Fig. 20 shown - is shifted upward in the direction of arrow 48, the front end portion of the rotary handle 14 is encompassed by lateral legs of the locking element 16, which is essentially U-shaped in this exemplary embodiment. Accordingly, it is not possible to swivel out the rotary handle 14 to the side in its front end region and the rotary handle 14 is in its locking position.

For simple handling, the locking element 16 has a handle part 50 in the form of laterally protruding flanges, with which a movement in the direction of arrow 47 or 48 is possible in a simple manner. In order to define an upper end position, the locking element 16 - as in FIG Fig. 21 can be seen - a projection 51 which is attached to a corresponding projection 52 (cf. Fig. 20 ) the receiving opening 53 in the binding body 4 for the locking element 16 strikes in the still shifted position.

Furthermore, latching projections 54 are again provided, which each project laterally in walls 55 of the regulating element 16 that run essentially perpendicularly. In the release position shifted downwards, these projections 54 snap into depressions 55 a, which are formed in the binding base body 4. In the upwardly shifted position, on the other hand, the projections 54 snap into recesses 55b in the binding body 4, so that the locking element 16 is secured in a latching manner both in the release position which has been displaced downwards and in the locking position which has been displaced upwards.

However, it is only essential that a locking element 16 is provided, which interacts with the rotary handle 14 in such a way that the blocking connection in the locked position cannot be released in a simple manner via an elastic deformation of an element and the rotary handle 14 is released for rotation.
