Description

The invention relates to a cross-country or touring ski binding for the articulated connection of a shoe to a ski, with a binding base body, which has a footprint for a sole of the shoe 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 extending in the transverse direction of the binding base body and a holding element for holding the shoe on the receptacle, the holding element being slidably mounted on the binding base body between a closed position holding the shoe on the receptacle and an open position releasing the shoe 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 basic binding body.

Such a ski binding is available from the applicant under the product name Turnamic. With ski bindings of this type, it is known that the twist grip and the binding base body have cooperating locking elements, so that the twist grip is held in the closed position.

A cross-country or touring ski binding with a base part for a rotary locking mechanism is known from US 9,022,411 B2. 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 an axle pin hole for receiving an axle 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 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. Even with such ski bindings 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.

/ 37

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 the force of gravity into the open position, a snap connection, i.e. a connection, which can be released in a simple manner when overcoming a (low) elastic restoring force of a locking element, is sufficient for securing the pivot lever in such ski bindings.

A completely different situation exists 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 position into the open position is not pivoted upwards against the force of gravity, but to open the binding the rotary handle only has to be swung out to the side. Although this is extremely advantageous in the handle for opening or closing the ski binding, it entails an increased risk that the twist grip is inadvertently rotated during use; i.e. is pivoted laterally about the axis of rotation arranged perpendicular to the contact surface, so that the ski binding is opened unintentionally. So far it was only known with 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, it is now the object of the invention to provide a locking of the turning handle in the closed position of the ski binding that goes beyond a mere securing of the turning handle by means of a latching connection.

According to the invention, this is achieved in that a locking element which can be transferred between a locking position and a release position is provided, the rotary handle being held in a non-rotatable manner relative to the circular binding body in the locking position and the rotary handle being released in the release position for a pivoting movement about its axis of rotation.

/ 37

By providing a positive connection in the locking position, the twist grip is reliably secured against unintentional twisting in the use position of the ski binding. According to the invention, a positive connection is 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 deform it elastically during the usually one-handed operation of the rotary handle, i.e. cannot release from the positive 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 into 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 a user-friendly operability when Verbzw. Unlocking the twist grip, it is advantageous if the locking element is mounted on the twist grip or the binding round body for transferring between the release position and the locking position. With the storage of the locking element on the twist grip, the locking element is easily accessible to the user. In addition, a reliable connection between the locking element and the turning handle is provided by the mounting on the turning handle, so that only the locking element or a section of the locking element is to be engaged with the element of the ski binding when the locking position of the turning handle is produced.

In a particularly simple and reliable manner, a rotationally fixed arrangement of the rotary handle in the locking position is achieved if, in the locking position, the locking element is positively connected to a binding base body in such a way that the turning handle is connected in a rotationally fixed manner to the binding base body via the locking element. To produce the locking position, it is therefore only necessary / 37 that a section of the locking element engages with the binding base body in a form-fitting manner, so that rotation of the rotary handle is reliably prevented.

Such a positive 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 twist grip is connected in a rotationally fixed manner to the binding base body. By means of the positive connection between the locking element and the binding base body, the twist grip on which the locking element is mounted is thus fixed in a rotationally fixed manner on the binding base body. In this position, the twist grip cannot be unintentionally released from the closed position, so that an unintentional opening of the binding, as is quite possible in the case of a mere snap-in connection to secure the closed position with the appropriate application of force, is reliably prevented.

A structurally simple configuration for the positive connection between the locking element and the binding base body is achieved if the locking element has a projection which is received in a receiving opening of the binding base body in the locking position. 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 between the locking position and the release position to move the locking element in such a way that the projection is either received in the receiving opening or - if release is desired - is removed from the receiving opening. The same applies essentially to the alternative configuration of a mounting on the binding body. If the locking element engages with the twist grip in the locking position, the twist grip is reliably secured against twisting by the connection to the binding base body via the locking element.

In order to prevent an unwanted release of the locking element from the locking position, it is furthermore favorable 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 latching connection is released from the locking position, this does not automatically lead to the locking element being transferred to the release position. Accordingly, even if the locking connection of the locking element is unintentionally released, the locking element can in principle still be arranged in its locking position.

With regard to ease of use 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, wherein the locking element in the locking position is preferably received at least in sections in a recess within the rotary handle. With the help of the pivotable mounting of the locking element on the rotary handle, it 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 for the user, due to its inclusion within the recess in the rotary handle, is hardly possible is perceptible, be transferred into an upward pivoted release position.

For particularly simple operation and structurally simple storage of the locking element in or on the rotary handle, it is advantageous if the locking element is pivotally 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 basic binding body is received.

As an alternative to the above-mentioned pivotable mounting of the locking element on the rotary handle, it is also conceivable that the locking element is slidably mounted in a recess in the rotary handle or in the binding base body between the locking position and the release position. Even with a / 37

Sliding movement, the locking element can be easily transferred from the locking position to the release position.

A high level of operating convenience can be achieved here if the locking element between the locking position and the release position is mounted so that it can be displaced essentially perpendicularly to the contact surface. In this embodiment, the user can thus easily pull on the locking element, so that the locking element is moved from a downward shifted locking position to an upward shifted release position.

In a structurally simple manner, an essentially linear displaceability of the locking element is achieved in that the locking element preferably has an elastic expandable pocket at least at one end, in which a web that extends substantially perpendicular to the contact surface is accommodated, the longitudinal extension of the pocket being greater than the longitudinal extension of the web. The design of the expandable bag means that when the locking element is first inserted into the ski binding, i.e. when assembling the individual binding parts, are easily inserted into the recess in the twist grip, so that the locking element is then guided in a longitudinally displaceable manner via the sliding interplay of the web and the 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 between the locking position and the release position is mounted so that it can be displaced in a substantially parallel or perpendicular manner 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 extension of which extends essentially parallel to the contact surface, the locking element having a web extending essentially parallel to the contact surface, which at least in the guide recess is partially recorded.

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

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

The displaceability of the locking element in the direction of the contact surface can be achieved in a simple manner by the longitudinal extent of the projection running essentially parallel to the contact surface. 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 which runs essentially perpendicular to the contact surface.

1 shows a cross-country or touring ski binding 1 for the articulated connection of a shoe (not shown) to a ski 2 (cf. FIGS. 3 and 4). 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 pivotable arrangement of a pivot axis of the boot running in the transverse direction of the binding base body 4 and a holding element 9 for holding the pivot axis of the boot in the receptacle 8. The holding element 9 is slidably mounted on the binding base body 4 between a closed position holding the shoe on the receptacle 8 (see FIGS. 3a, 3b and 4a, 4b) and an open position releasing the shoe (see 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 that can be transferred between a locking position and a release position can be seen. In the first 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, preferably almost entirely, in the locking position. In the locking position of the locking element 16, the turning handle 14 is held non-rotatably with respect to the binding round body 4/37, the locking element 16 being mounted on or in the turning handle 14 between the locking position and a release position.

As can be seen in FIGS. 3a and 3b, in the locking position the locking element 16 is positively connected to the binding base body 4 in such a way that the twist grip 14 is connected to the binding base body 4 in a rotationally fixed manner. For this purpose, the locking element 16 has a projection 16a, which is received in the locking position in a receiving opening 19 (cf. FIG. 2) of the binding base body 4.

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

The locking element is secured in the locking position via a snap connection. For this is on the back, i.e. facing in the direction of the shoe holder, a locking element 20a is provided on the locking element 16 and a locking 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 latching element 20b is preferably raised and elastic and, in the locking position, engages in the latching element 20a designed as a corresponding depression to secure the rotary handle 14 in the closed position. As an alternative or in addition to the locking element 20a, the locking element 16 can also have a further locking element, preferably in the form of 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. The notch 20c is then preferably formed on the rear leg of this U's in a forward-facing wall, which notch is locked in the locking position of the locking element 16 to secure it / 37 in the locking position with a corresponding binding body-side projection (not shown).

3c shows an alternative embodiment of the locking element 16 of the first exemplary embodiment, which has an additional notch 17b. The notch 17b extends upward from an underside of the locking element, in particular perpendicularly to the contact surface 5a, so that the locking element has a 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 locking element 28 - e.g. - vary due to different shrinkage values of locking element 16 and binding base body 4. With the help of the notch 17b increasing the flexibility of the locking element 16, a smooth locking and unlocking is thus ensured.

6 to 8 and FIGS. 9 to 12 show two further exemplary embodiments in which the locking element 16 is displaceably mounted in the recess 18 in the rotary handle 14 between the locking position and the release position.

In the second exemplary embodiment according to FIGS. 6 to 8, the locking element 16 is mounted between the locking position and the release position in the direction of displacement 22a, essentially perpendicular to the contact surface 5a. For this purpose, the locking element 16 has a pocket 23 which is delimited by two side wall elements 24a, 24b, at least one of the two wall elements 24a, 24b having a latching hook 25 at its freely projecting end and being elastically deformable. In this way, the locking element 16 can be inserted into the recess 18 under the elastic deformation in at least one of the two wall elements 24a, 24b. Here, with elastic deformation, at least one of the two wall elements 24a, 24b and a web 26 of the twist grip 14 extending essentially perpendicular to the contact surface 5a is encompassed. In the relaxed state of the two wall elements 24a, 24b, the locking element 16 is guided essentially in a linear direction 22a by the accommodation of the web 26 in the pocket 23, so that the locking element 16 can be moved in a simple manner from a lower locking position displaced in the direction of the contact surface 5a / 37 (Fig. 8) in an upward shifted release position (Fig. 7) in the direction of displacement 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 can be seen in FIG. 7, in the released 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 above a latching projection 28 on the rotary handle side in the upper release position, so that the locking element is held in the release position via the latching connection.

8 shows the locking element 16 in its locking position which is shifted downwards and in which a large part of the locking element 16 is received in the recess 18 in the rotary handle 14. As can be seen in FIG. 8, 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 side walls 30 of the rotary handle 14, which laterally enclose the recess 18. In addition, the locking projection 28 latches in a correspondingly designed locking recess 31 on an elastically pivotable wall element 32 of the locking element 16. Furthermore, it can be seen that the projection 16a of the locking element 16 projects downward and thus in the locking position in a recess 19 arranged in the binding base body 4 is positively received. In this position of the projection 16a accommodated in the recess 19, rotation of the rotary handle 14 about its pivot axis 15 is thus impossible, so that the holding elements 9 are prevented from being opened unintentionally.

In the third embodiment according to FIGS. 9 to 12, the locking element between the locking position and the release position in the direction of displacement 22b is displaceably releasably guided essentially parallel to the contact surface 5a. 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 ease of use, 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 direction of displacement 22b.

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

In order to lock the locking element 16 in the locking position and in the release position, locking projections 38 are provided on the side walls, which cooperate with two locking recesses 39 which are offset from one another in the direction of displacement 22b and are each provided on a side wall of the recess 18 of the rotary handle 14. Of course, an inverted arrangement of the locking projections / recesses on the locking element 16 and the rotary handle 14 is also possible.

As can be seen in the locking position of the locking element 16 shown in FIGS. 10 and 12, the projection 16a thus projects in the locking position relative to the rear of the walls 30 delimiting the recess 18 and can thus engage in the receiving opening 19 on the binding side.

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

/ 37

FIGS. 13a, 13b and 14a, 14b show a further exemplary embodiment, in which the locking element 16 is pivotably mounted in a front end region of the binding base body 4 about a pivot axis 41. For the formation of the pivot axis 41, the locking element has two laterally projecting stub axles 42 which are arranged at the ends on resilient webs 43. By means of elastic deformation of the resilient webs 43, the two stub axles 42 can be brought closer to one another and can be accommodated in corresponding receiving openings in the binding base body 4. The end of the locking element 16 opposite the pivot axis 41 has a transverse handle 44, via which the user can easily grip the locking element 16 and between the release position shown in FIGS. 13a and 13b and the locking position shown in FIGS. 14a, 14b can pivot. In the locking position shown in FIGS. 14a, 14b, it can be seen that locking element 16 is accommodated in sections in the recess 18a in the rotary handle 14, which is delimited laterally 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 on the resilient webs 43 each has lateral projections 45 (see FIGS. 15a, 15b), which in corresponding recesses 46a, 46b on the binding base body 4 in the Snap release or on the rotary handle 14 in the locking position and thus secure the locking element 16 in the respective position.

16 and 17 and 18a, 18b show a fifth exemplary embodiment in which the locking element 16 is mounted in the front end region of the binding base body 4, as in the previous exemplary embodiment. In contrast to the previous exemplary embodiment, the locking element 16 in this exemplary embodiment is, however, displaceably mounted in the binding base body 4. As shown in Fig. 16, the binding base body 4 has a recess 46a / 37 in which the locking element 16 is slidably mounted. In the position shifted downward in the direction of arrow 47, the upper end of the locking element 16 does not protrude into a recess 46b on the side of the handle, so that the handle 14 is supported in an unobstructed manner. However, if - as in Fig.

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 twist grip 14, so that twisting of the twist grip 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 exemplary embodiment has locking 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 simple operation of the locking element 16 according to FIGS. 16, 17, 18a and 18b, the locking element 16 has a grip part 50 which can be actuated by hand without an additional tool in order to move the locking element in the direction of the arrows 47 and 48, respectively ,

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

If, however, the locking element 16 - as shown in FIG. 20 - is shifted upward in the direction of arrow 48, the front end section of the rotary handle 14 is encompassed by side legs of the locking element 16, which in this exemplary embodiment is essentially U-shaped. Accordingly, a lateral pivoting out of the rotary handle 14 in its front end area is not possible and the rotary handle 14 is in its locked position.

/ 37

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

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

It is only essential, however, 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 by means of an elastic deformation of an element and the rotary handle 14 is released for rotation.
