Description

The invention relates to a ski binding, in particular cross-country binding, with a binding element which is slidably mounted on a provided for arrangement on a ski slide and its arrangement seen in the longitudinal direction of the slide in different positions by means of a locking device can be fixed, the locking device in a blocking position binding - And skiseitig has interlocking locking elements and the binding-side locking element comprises a lever element which is pivotable such that in a displacement position, the locking elements are not engaged and the binding element is slidably mounted relative to the slide rail.

In the prior art a variety of slide rails or binding plates are already known, on which in particular a binding element of a cross-country binding is slidably mounted. In order to set the arrangement of the binding element on the ski or relative to the slide individually or adapt to the respective snow conditions, it is known to provide a locking device with which the binding element can be set in different positions on the slide.

For example, is from the WO 2015/140258 A1 already such a locking device for cross-country bindings, in which a pivotally mounted locking lever cooperates with a binding-side locking projection. Latching elements projecting from the latching lever are provided for receiving latching openings provided in the slide rail in order to position the binding element relative to the binding plate. Here, in a preferred embodiment, the lever element is arranged in a preloaded release position and can be converted by means of a slider in the locked position. The disadvantage here is in particular that the elastic bias of the plastic material is inter alia dependent on the temperature and the age of the binding element, so that a transfer is not ensured in the release position.

Furthermore, for example, from the EP 2 090 338 A1 a cross-country binding with a binding plate known on which a Binding element is slidably mounted. In order to determine the position of the binding element relative to the binding plate, the binding plate has a plurality of openings in which an end-side latching hook of the binding element can be accommodated. Here, however, a tool such as a screwdriver or the like is required for opening.

A similar cross-country binding, in which also a tool is required to bring a locking element of the binding element of a latched connection with a binding plate, is further from the US 2013/0241179 A1 known.

The aim of the invention is therefore to provide a ski binding of the type mentioned, in which the locking elements can be reliably transferred reliably and without tools in a release position in a simple and efficient manner, in which the binding element is variable in its position relative to the slide rail.

According to the invention, this is achieved in that the binding element has an operating element with an oblique contact surface, which can be transferred between an open position and a closed position, wherein the oblique contact surface of the operating element cooperates with an oblique contact surface of the lever element when transferring the operating element into the open position. the lever element is moved out of the blocking position.

With the help of the operating element according to the invention thus the lever element can be reliably moved from a locked position with the ski-side locking element, in particular lifted, and thus be ensured in a simple and reliable manner that by a simple displacement of the operating element of a closing in an open position, the lever element of the locking device is released from the locked position and is transferred to the displacement position, so that the binding element is released for displacement on the slide rail. Under skiseitigem locking element is a locking element to understand that connected either directly to the ski or with the slide is or is designed in one piece and thus to determine the position of the binding element relative to the slide rail or the ski, on which the slide is fixedly disposed in use, cooperates with a locking element of the binding element in the blocking position.

The oblique casserole and abutment surfaces of the operating element and the lever element can be configured either flat or curved. It is merely to be ensured that during the transfer of the operating element from the closed to the open position, the cooperating casserole and contact surfaces do not block each other when the lever element is released from the blocking position.

To ensure that the lever element is reliably arranged in a blocking position and thus to avoid accidental release of the locking connection during use - regardless of the ambient temperatures or by the creep behavior of the plastic material of the lever element - if possible, it is advantageous if the lever element so is formed so that it is arranged in a relaxed starting position in the blocking position. Accordingly, it is necessary for the transfer of the lever member in a locking position no separate locking element or the like., But the lever member is advantageously - if no external forces act on it - in its blocking position, so that a reliable locking connection is achieved.

In order to further increase the ease of use for the user, it is advantageous if the lever element does not have to be permanently held on the slide rail during the sliding operation of the binding element, but can be fixed in its open position in a simple manner. In this context, it is advantageous if the operating element and the lever element have cooperating displacement locking elements which snap into one another during the transfer of the operating element into the open position. With the help of these sliding locking elements thus the operating element when transferring into its open position in a simple manner by a preferably for the user also feel or audible snapping the cooperating displacement locking elements - Tool-free - be held in the open position, so that in a simple way the binding element can be moved relative to the slide rail. Accordingly, it is advantageously not necessary on the one hand to hold the lever element in its open position and at the same time to displace the binding element with respect to the slide rail, which sometimes requires a certain dexterity in the case of known ski bindings.

With regard to a structurally simple embodiment of the sliding latching elements for the purpose of latching connection between the operating element and the lever element in the open position of the operating element, it is advantageous if a preferably web-shaped latching lug and a recess for receiving the latching lug preferably linear locking groove are provided as sliding latching elements. Accordingly, advantageously only a projecting web, in particular on the operating element and a corresponding groove-shaped recess, preferably provided on the lever element, so that the two elements are brought in the transfer of the operating element in a latching connection, which can be solved in a simple manner again.

Likewise, it is advantageous for the ease of use of the user when he experiences a feel or audible feedback not only when transferring to the open position of the operating element that the operating element has now been successfully transferred to the open position, but the same for the transfer to the Closed position applies.

Accordingly, it is advantageous if the operating element and a substantially plate-shaped base element of the binding element have cooperating locking detent elements which snap into one another during the transfer of the operating element into the closed position. When transferring the operating element a latched position of the operating element is thus achieved when reaching the closed position, so that the user obtains security that the binding element is now arranged in the locked position.

With regard to a structurally simple embodiment of Locking latching elements, it is advantageous if the operating element has a resiliently deformable groove as a locking-latching element, in which in the closed position a with the plate-shaped base element connected, preferably pin-shaped, locking snap-in element snaps.

With regard to a compact construction of the binding element, it is further favorable if the operating element is movably received in a recess of the plate-shaped base element of the binding element. By providing a recess in the plate-shaped base member, the operating element can be integrated in a practical and elegant manner in the plate-shaped base element of the binding element and stored within this recess, in particular displaceable or pivotable, for transferring between the open and the closed position.

With regard to a structurally simple embodiment for the displaceable mounting of the operating element in the recess of the base member, it is advantageous if the operating element edge-side webs, which cooperate with the edge projecting into the recess guide webs of the plate-shaped base member.

To further increase the certainty that the lever element remains in the blocking position when the operating element is arranged in the closed position, it is furthermore advantageous if the operating element has a securing section which overlaps in the blocking position at least partially overlapping with at least one securing surface of the Lever element is arranged.

In this case, it is advantageous in terms of a structurally simple embodiment with a low overall height if, as a securing section at the free end of the lever element, projecting securing surfaces are provided laterally by a substantially rectangular lever arm whose upper side are arranged below the upper side of the lever arm.

The operating element therefore preferably comprises sections in the manner of a clamp the lever arm, wherein in the locked position of the operating element then an end-side securing portion of the lever member is covered by a portion of the operating element, so that pivoting of the lever element - contrary to its relaxed initial position - is additionally prevented; the lever arm is thus secured in its locked position.

In order to adjust the vertical position of the operating element, i. perpendicular to the direction of displacement of the operating element, set in the closed position and thus reliably avoid that the lever element in the locking position together with the operating element can be released from the locked position, it is advantageous if the operating element and the recess in the control element in its blocking position in a Has direction perpendicular to the direction of displacement of the operating element locking groove / spring connection.

In order to separate the snap connection with the ski of the sliding guide between the binding element and the slide rail and thus - due to the different stresses - e.g. the possibility to open for the locking element to provide a different material compared to the slide rail, it is advantageous if the at least one, provided on the ski side locking element in a separate rail of the slide engagement rail, which is preferably directly connected to the top of the ski, in particular glued, is, is educated.

With regard to a reliable latching connection in the blocking position, which reliably prevents unintentional release in both possible displacement directions, it is favorable if the ski-side latching element has at least one, in particular cylindrical, receiving opening preferably a plurality of receiving openings arranged at the same distance from one another.

In order to achieve an intimate latching connection, it is correspondingly advantageous if the binding-side latching element has at least one pin-shaped latching element, it being found to be advantageous if at least two pin-shaped latching elements are provided.

Of course, it is also possible to provide other different receiving openings or projecting locking elements, which provide an unintentional release at a force in one of the two possible displacement directions of the binding element.

In order to allow a particularly simple handling when transferring the operating element between the open and closed positions, it is furthermore advantageous if the operating element has at least one recess and / or recess on an upper side facing away from the slide rail.

The invention will be explained in more detail below with reference to preferred embodiments, to which, however, it should not be limited.

In Fig. 1 is a ski 1 can be seen, on which a slide or binding plate 2 is arranged. The slide rail 2 is in this case screwed to the ski 1 and / or glued or can also be integrally formed with an upper laminate of the ski 1.

In the exemplary embodiment shown, a locking element 3 designed separately from the slide rail or binding plate 2 is provided in the form of a latching or engagement rail 3 ', which has a multiplicity of essentially cylindrically configured receiving openings 4. The locking rail 3 'is in this case received in a recess of the slide rail 2 and - separately from the slide rail 2 - connected to the ski 1, in particular glued and / or screwed.

The slide rail 2 has in known manner at the longitudinal edges of projecting slide rails 2 ', which are accommodated for displaceable mounting of a binding element 5 in groove-shaped recesses 6 of the binding element 5 (see. Fig. 3 ), when the binding element 5 is pushed onto the slide rail 2.

In Fig. 2 the binding element 5 is then shown in a pushed-on on the slide 2 position, it can be seen that the binding element 5 has two viewing window 7, by which a review of a position indicator 8 on the top of the slide rail 2 is possible.

Furthermore, it can be seen that the binding element 5 for use as cross-country or Telemarkbindung in the front end portion has two hook-shaped holding elements 9, which are provided for receiving a pivot axis of a ski boot. In the position fastened to the binding element 2, a ski boot, in particular cross-country skiing or telemark boot, is thus pivotably mounted about the pivot axis received in the retaining elements 9.

In addition, in particular in 4 and 5 an operating element 10 can be seen, which is arranged in a closed position, in which an operable by the operating element 10 locking element 11 is arranged in its blocking position. The operating element 10 is in a recess 13 in a plate-shaped base member 17 of the binding element 5 between the closed position and an open position (see. Fig. 9 ) stored in particular displaceable. For this, the recess 13 has laterally projecting guide webs 13 ', on which the operating element with lateral webs 10''(see. Fig. 10b ) is slidably mounted, wherein - as also in Fig. 9 seen - the operating element 10 is also slightly pivoted in the open position of the elastic restoring force of the lever member 12.

As in particular in Fig. 6 it can be seen, as a connection-side locking element 11, a lever member 12 is provided which is arranged in a locking or locking position such that with a lever arm 12 'connected locking pins 12''in corresponding, in the embodiment shown, cylindrical receiving openings 4 in the locking rail. 3 'are included.

Here, the lever member 12 is positioned in its relaxed starting position such that for releasing the lever member 12 from the locking position, a pivoting of the lever member 12 is required from its relaxed starting position. For this purpose, the operating element 10 is provided, with which the lever element 12 can be deflected substantially about a pivot axis 14 (see, in particular, also FIG. 9 ).

In the sectional view according to Fig. 6 is further seen that the operating element 10 in the in Fig. 3 to 6 shown blocking position of the lever member 12 is arranged in a latched closed position. For this purpose locking detent elements 15, 16 are provided.

In the embodiment shown are as locking-latching elements 15, 16, a pin-shaped locking element 15 ', which is angordnet on the underside of the substantially plate-shaped base member 17 of the binding element 5, and a groove 16' in the operating element 10 is provided. In this case, the groove 16 'is tapered from an inlet opening to a constriction, to which a cylindrical detent opening 16 "adjoins the detent position in order to receive the pin-shaped detent element 15. When passing over the constriction, the groove 16' thus expands elastically, so that subsequently the pin-shaped catch element 15 'snaps into the latched position Fig. 5 apparent closing position is thus the acquisition of the closed position due to the Einschnappvorgangs audible and perceptible to the user; The same applies - as explained in more detail below - for the transfer of the operating element 10 in the open position.

In Fig. 4 is also apparent that the operating element 10 has a securing portion 18 in an end portion facing the lever element 12, which cooperates with a securing portion 19 of the lever element 12 (cf. Fig. 10b , Control element 10 and lever member 12 are formed such that the securing portion 18 of the operating element 10 in the in Fig. 6 shown blocking position in the securing portion 19 from the lever arm 12 'laterally projecting securing surfaces 19' (see also FIGS. 10b and 11 ) of the lever element 12. In this way, in the blocking position of the operating element 10 pivoting of the lever member 12 in a displacement position in which the or the locking pins 12 '' from the or the receiving opening (s) 4 are solved reliably prevented.

To the operating element 10 in the closed position in vertical Direction to fix, in the closed position is also a positive key / spring connection 25, 26 between the operating element 10 and base member 17 before. In the embodiment shown, the operating element 10 lateral grooves 25 and the recess 13 in the base member 17 over a portion of the longitudinal extent of the recess 13 laterally projecting springs or hold-down webs 26. When transferring the operating element 10 in the closed position, the retaining grooves 26 projecting laterally into the recess 13 are thus received in the grooves 25, so that the vertical position of the operating element 10 is defined in its closed position by the form-locking tongue and groove connections.

In the Fig. 7 to 9 It can be seen that with the aid of the operating element 10, in particular the lever element 12, can be converted into its displacement position.

For this purpose, the operating element 10 is displaced in the direction of the lever element 12, wherein the operating element 10 at its end facing the lever element 12 end portion 10 'oblique ramp surfaces 20 (see also Fig. 10a ), which cooperate with the lower inclined contact surface 21 of the lever member 12, so that the operating element 10 in the in 4 to 6 shown closed position is released and the lever member 12 is pivoted from the closed position upwards. For ease of handling, the operating element 10 has a recess 27, in which a finger of the user for the purpose of moving the operating element 10 can be accommodated.

After using the end ramp surface 20, the lever member 12 is pivoted upwardly from its substantially relaxed starting position, are in further moving - as in particular in the Fig. 11 shown intermediate position of the operating element 10 can be seen - brought by the accumulating on the ramp surface 20 of the operating element 10 contact surface 21 of the lever member 12, the locking pins 12 '' out of engagement with the receiving openings 4 of the locking rail 3 'until the operating element 10 in the in Fig. 9 shown end or open position passes.

When the operating element 10 has reached its end or open position, moreover, a web 22 ', which is provided on the underside of the front end section of the lever element 12, snaps into a groove-shaped depression 23' (cf. Fig. 10a ) of the operating element 10. About this latching connection between the formed as a sliding-locking elements 22, 23 web / groove connection 22 ', 23', thus the lever member 12 is held in its displacement position, so that the user can easily move the binding element 5 on the slide rail 2.

Here, the user can also take on the viewing window 7 mounted on the slide position indicator 8 insight and as soon as the desired position is achieved by moving the operating element 10 in the particular in Fig. 6 shown locking position, the lever member 12 in turn returned to its relaxed starting position, so that the locking pins 12 engage in corresponding cylindrical receiving openings 4 in the locking rail 3 ', so that a displacement of the binding element 5 relative to the slide rail in the then obtained locking position of the lever member 12 and closed position the operating element 10 is not possible.

Thus, a simple and tool-free to use ski binding is created with the device according to the invention, in which the position of the ski binding against the ski 1 and a slide rail 2 is changed in a simple and handy way.
