Description

ski binding

The invention relates to a ski binding, in particular cross-country binding ^¬ , with a binding element which is slidably mounted on an intended for arrangement on a ski slide rail and whose arrangement in the longitudinal direction of the slide seen in different positions by means of a locking device can be fixed, wherein the locking device in a Locking position binding and skiseitig interlocking locking elements on ^¬ has and the binding-side locking element has a lever element ^¬ , which is pivotable such that in a displacement ^¬ order 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 against the slide individually or adapt to the respective snow conditions, it is known to provide a Rastvorrich ^¬ tion, with which the binding element can be set in different ^¬ union positions on the slide.

For example, a derar ^¬ term locking device for cross-country bindings is already known from WO 2015/140258 AI, in which a pivotally mounted locking lever cooperates with a binding-side locking projection. Latching elements projecting from the latching lever are provided here for receiving in the sliding rail provided latching openings in order to positio ^¬ the binding element 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, a long ^¬ country binding with a binding plate is known for example from EP 2090338 Al, on which a binding element is displaceably mounted. In order to determine the position of the binding element with respect 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. However, this is to open a tool, such as a screwdriver or the like. , required.

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 known from US 2013/0241179 AI.

The aim of the invention is therefore to provide a ski binding of the initially mentioned type, in which the locking elements can be reliably reliably and werk ^¬ zeuglos reliably transferred to a release position in a simple and efficient manner in which the binding element is variable in its position relative to the slide rail.

This is achieved in that the Bindungsele ^¬ ment has an operating member with an oblique Auflaufläche on ^¬, which can be transferred between an open and a closed position, wherein the oblique Auflaufläche of Bedienungsele ^¬ ments during the transfer of the operating member into the open Stel ^¬ lung with the present invention, cooperates an oblique contact surface of the lever element in such a way that the lever element from the locked position be ^¬ is moved.

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 ensured in a simple and reliable manner that by a simple displacement of Bedienungsele ¬ with the help of cooperating casserole / contact surfaces ^¬ ment of a closed 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. U.N- ter skiseitigem locking element is a locking element to understand that is connected either with the ski directly or with the slide ^¬ is connected or is also designed in one piece and thus determining the position of the binding element relative to the

Sliding rail or the ski on which the slide is arranged fixed in Ge ^¬ use state, cooperating with a locking element of the binding element in the locking 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.

In order to ensure that the lever member 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 Kunststoffma- terials the lever element - as far as possible, it is advantageous if the Lever element is designed such that it is arranged in a relaxed starting position in the blocking position. Accordingly, it requires for the transfer of the lever member in a locking position no separate Sperrele ^¬ management or the like. but the lever element is located before ^¬ geous enough - if no external forces act on it - in its blocking position, so that a reliable locking connection is achieved.

To increase the ease of use for the user further, it is advantageous if the lever element during the displacement ^¬ gangs of the binding element on the rail must not be kept permanently, but can be fixed easily in its open position. In this context, it is advantageous if the operating element and the lever element have to ^¬ sammenwirkende displacement-locking elements which snap into each other when transferring the operating element in the open position. With the aid of these displacement locking elements, the operating element can thus be transferred to its open position. development in a simple manner by a preferably the user also tactile and audible snapping the cooperating encryption push-latching elements - are in the open position held ^¬ th, so that the binding element ge ^¬ genüber the slide can be moved easily - without tools. Accordingly, it is advantageously not necessary on the one hand to keep the Hebelele ^¬ element in its open position and at the same time to move the binding member relative to the guide rail, which the user sometimes demands a certain amount of dexterity in known ski bindings.

With regard to a structurally simple embodiment of the sliding latching elements for the purpose of locking connection between Bedienungs ^¬ element and lever element in the open position of Bedienungsele ^¬ ment, it is advantageous if provided as a sliding locking elements preferably a web-shaped locking lug and a preferably for receiving the locking lug locking groove are. Accordingly, advantageously only a projecting web, in particular ^¬ special on the operating element and a corresponding groove-shaped depression, 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 member of the binding element cooperating locking catch elements comprise at which snap over ^¬ result of the operation member in the closed position together. When transferring the operating element, a latched position of the operating element is thus achieved when reaching the closed position, so that the user safety he reached ^¬ that the binding element is now ^¬ in the locked position is arranged. With regard to a structurally simple embodiment of

Locking latching elements, it is advantageous if the Bedienungsele ^¬ ment as a locking-latching element has an elastically deformable groove ^¬ in which in the closed position a with the plate-shaped base element connected, preferably pin-shaped locking snap 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 element, the operating element can be integrated in a practical and elegant way in the plate-shaped base member of the binding element and stored within these off ^¬ 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 element, it is advantageous if the operating element edge-side webs, which cooperate with the edge projecting into the Ausneh ^¬ tion guide webs of the plate-shaped base member.

To further increase the certainty that the lever element remains in the locking position when the operating element is arranged in the closed position, it is further of advantage if the control element comprises a fuse portion which in the locked position at least partially overlap area ^¬ pend with at least one Secured surface of the lever element is arranged on ^¬ .

Here, it is advantageous in terms of a structurally simple design with a low overall height, when the locking portion at the free end of the lever member laterally of ei ^¬ nem substantially rectangular lever arm projecting locking surfaces are provided, whose top are arranged below the top of the lever arm. Preferably, the operating element comprises consequently from ^¬ cut in the manner of a clip the lever arm, whereby then an end securing portion of the lever member is covered by a portion of the operation member in the locking position of the operating member so that pivoting of the lever member - is additionally prevented - contrary to its relaxed initial position ; the lever arm is thus secured in its locked position.

In order to fix the vertical position of the operating element, ie perpendicular to the direction of displacement of the operating element in the closed ^¬ position and thus reliably avoid that the lever element in the locked position including Bedienungsele ^¬ ment can solve from the locked position, it is advantageous if the Operating element and the recess has a ^{Bedienungsele ¬} ment in its blocking position in a direction perpendicular to the direction of displacement of the operating element locking tongue and groove connection.

In order to separate the locking connection with the ski of the sliding guide between binding element and slide and thus - due to the different stresses - eg the possibility to open for the locking element a difference ^¬ liches material compared to the slide provide, it is advantageous if the at least one, on the ski side provided Ras ^¬ telement in a separate from the slide rail engagement ^¬ rail, which preferably ver ^¬ connected directly to the top of the ski, in particular glued, is formed.

With regard to a reliable snap connection in the locking position, which reliably prevents inadvertent release in both possible directions of displacement, it is favorable if the skiseitige locking element preferably has at least one, in particular Cylind ^¬ generic, receiving aperture a plurality of mutually equally spaced receiving apertures.

In order to achieve an intimate latching connection, it is correspondingly advantageous if the connection-side latching element has at least one pin-shaped latching element, whereby it can be used as a has partially proven if at least two pin-shaped locking elements are provided.

Of course, it is also possible to vorzuse ^¬ other types of receiving openings or projecting locking elements, which provide an unwanted release in a force in one of the two possible displacement directions of the binding element.

In order to enable a particularly simple handling when transferring the operatability ^¬ tion element between the open and closed position, it is also advantageous if the operating element has at least one recess and / or recess on an upper side remote from the slide rail top.

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

In detail, in the drawings:

FIG. 10b shows in detail a bottom view of the operating element according to FIG. 10A; FIG. and

Fig. 11 in detail a plan view of the ski binding with the Be ^¬ serving element in an intermediate position.

In Fig. 1, a ski 1 can be seen, on which a slide rail 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 embodiment shown, a separate executed by the slide rail or binding plate 2 locking element 3 in the form of a latching or engagement rail 3 'is provided, which egg ^¬ ne plurality of substantially cylindrically shaped receiving openings 4 has. The locking rail 3 'is in this case received in egg ^¬ ner 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 2 has in a conventional manner to the

Longitudinal edges projecting slide rails 2 ', which are accommodated for displaceable mounting of a binding element 5 in groove-shaped depressions 6 of the binding element 5 (see Fig. 3), when the binding element 5 is pushed onto the slide rail 2 ^¬ .

In Fig. 2 is then the binding element 5 in a on the Sliding rail 2 shown deferred position, wherein it is apparent ^¬ lich that the binding element 5 has two viewing window 7 ^¬ , through 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 attached to the Bin ^¬ dung element 2 position is thus a ski boot, in particular cross-country or telemark boot to the stored recorded in the Halteele ^¬ elements pivot axis 9 pivotable.

In addition, in particular in Fig. 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 Rastele ^¬ ment 11 is arranged in its blocking position. The Operation ^¬ element 10 is mounted displaceably in particular in a recess 13 in a plate-shaped base member 17 of the binding element 5 between the closed Stel ^¬ lung and an open position (see. Fig. 9). For this purpose, 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 shown in Fig. 9 - the operating element 10 in the Open position of the elastic restoring force of the lever member 12 is also slightly pivoted.

As can be seen in particular in FIG. 6, a lever element 12 is provided as a locking side locking element 11, which is arranged in a locking or detent position such that with a lever arm 12 'connected locking pins 12' 'in corresponding, in the embodiment shown, cylindrical Receiving openings 4 are received in the locking rail 3 '.

Here, the lever member 12 is positioned in its relaxed position output ^¬ such that for releasing the lever member 12 from the locking position pivoting of the lever member from its relaxed initial position is required 12th For this purpose, the operating element 10 is provided, with which the He- Belelement 12 can be deflected substantially about a pivot axis 14 (see, in particular, Fig. 9).

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

In the embodiment shown are as locking locking 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. The groove 16 'is in this case from ei ^¬ ner inlet opening to a constriction tapered ausgebil ^¬ det, to which a cylindrical latching opening 16''for receiving the pin-shaped locking element 15' in the latched position connects. When passing over the constriction, therefore, the groove 16 'expands elastically, so that subsequently the pin-shaped detent element 15' snaps into the latched position. When transferring the operating element 10 in the particular in Fig. 5 apparent closing position thus obtaining the closed position due to the Einschnappvorgangs is audible and palpable for the user; The same applies - as explained below in De ^¬ tail - for the transfer of the operating element 10 in the open position.

In FIG. 4 also Be ^¬ dienungselement can be seen that the operating member 10 has a securing portion 18 in a directed toward the lever member 12 end portion with a Sicherungsab ^¬ section 19 of the Hebelelments 12 cooperates (see Fig. 10b. 10 and lever member 12 are such formed so that the securing portion 18 of the operating member 10 covers as shown in Fig. 6 locking position in the locking section 19 from the lever arm 12 'laterally projecting securing surfaces 19' (see. also FIG 10b and FIG. 11) of the lever member 12. ^¬ is here in the locking position of the operating element 10, a 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. In order to fix the operating element 10 in the closed position in the vertical direction, in the closed position is also a positive tongue and groove connection 25, 26 between the operating ^¬ element 10 and base member 17 before. In the illustrated example exporting ^¬ approximately the operating member 10 has 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 retaining ribs 26. When transferring the Bedienungsele ^¬ ments 10 in the closing position respectively, the laterally projecting into the recess 13 hold-down bars 26 are thus received in the grooves 25 so that defines the vertical position of the operating element 10 in its closed position by the form ^¬ locking groove / spring connections is.

In Figs. 7 to 9 it is apparent that can be converted into its displacement position by means of the voltage Bedie ^¬ elements 10, in particular the lever element 12.

For this purpose, the operating element 10 is displaced in the direction of Hebelele ^¬ element 12, wherein the operating element 10 at its end facing the lever member 12 end portion 10 'inclined on ^¬ running surfaces 20 (see also Fig 10a), which with the lower inclined contact surface 21 of the lever member 12 cooperate, so that the operating element 10 is released in the closed position shown in Fig. 4 to 6 ^¬ and the lever member 12 is pivoted from the closed position upwards. For easy ^¬ ren 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 added.

After the Hebelele ^¬ element 12 from its substantially untensioned starting position pivoted upwards by means of the end-side run-up surface 20, when further displacement - seen in particular in the embodiment shown in Figure 11 intermediate position of the operating member 10 -. By on the on ^¬ tread 20 of the operating element 10 accumulating 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 'brought to the Be ^¬ serving element 10 in the end or in Fig. 9 shown. reached.

If the operating element has its end or open position reached 10 he ^¬, also snaps web 22 ', which is provided on the Untersei ^¬ te the front end portion of the lever member 12 in a groove-shaped recess 23' (see FIG. Fig. 10a) of the Be ^¬ dienelements 10 a. About this latching connection between the slide-locking elements 22, 23 formed 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 8 insight into the viewing window 7 mounted on the slide rail position indicator and once the desired position is achieved, is the lever member 12 is again relaxed in its by a Ver ^¬ push the operation member 10 in particular in Fig. 6 shown locking position Returned home position so that the locking pins 12 engage in corresponding cylindrical receiving openings 4 in the locking rail 3 'in engagement, so that a displacement of the binding member 5 relative to the slide in the then he ^¬ targeted locking position of the lever member 12 and the closed position of the operating element 10 is not possible.

Thus, a simple and tools to use the ski binding is provided with the inventive device in which in a simple and handy way the position of the ski binding ge ^¬ genüber the ski 1 and a slide 2 is variable.
