"Cross-country or telemark binding"

Description

The invention relates to a cross-country or telemark binding according to the preamble of claim 1.

Such a bond is well known. It comprises engagement elements which are engageable with complementary engagement elements on the sole of a ski boot in engagement such that the shoe heel is freely raised. In this regard, reference is made, by way of example only, to WO 01/93963 A1, which is based on the Applicant.

The present invention is also intended to refer to bindings which are longitudinally slidably mountable on top of a ski.

The object of the present invention is to further develop the known bonds in such a way that a high level of assembly friendliness is obtained with simple production. The binding should in particular be designed such that it can be mounted as a unit on a mounting plate or rail on the top of a ski without fastening screws or rivets.

This object is achieved by the characterizing features of claim 1, wherein further details and constructive embodiments are described in the subclaims.

A basic idea of the present invention is that the binding-side engaging elements associated bearing firmly anchored on a in the binding housing, in particular on the underside of a binding housing associated bottom plate Mounting plate, in particular metal plate, are held. The usually made of metal bearings are therefore part of a likewise made of metal mounting plate.

The binding housing including bottom plate is usually made of plastic. The mounting plate is bonded to either the binding housing or the bottom plate of the same, or alternatively cast in the binding housing or in the bottom plate. Preferably, the mounting of the mounting plate on the underside of the binding housing or the bottom plate of the same takes place such that the mounting plate with the bottom of the binding housing or the bottom plate is flush. This construction is particularly suitable for a binding which is displaceably mounted along a rail mounted on the upper side of a ski.

The bearings associated with the binding-side engagement member comprise pivot bearings having upstanding cheeks for receiving hinge axes, the aforementioned cheeks extending through the base plate of the binding housing into the shaft

Inner of the binding housing extend into it. The bottom plate of the binding housing naturally has corresponding passage openings. By the mounting plate, a high stability of the bottom plate and thus also of the binding housing is obtained even with thin-walled overall construction.

Preferably, two front, one front pivot bearing and two rear, a rear pivot bearing defining cheeks are held by a common mounting plate. Both the front pivot bearing and the rear pivot bearing each have a transverse to the ski or binding longitudinal direction extending horizontal axis. To the front pivot bearing associated horizontal axis an actuator, in particular actuating lever is pivotally mounted, while a sole engagement element, in particular Eirigriffshaken is pivotally mounted about the rear pivot bearing associated horizontal axis.

In a further concretization of the present invention, the sole-side engagement elements are arranged by a disposed within a sole recess transverse axis on the one hand and a arranged between the front and the sole end projection on the other hand, and the respective associated binding-side engagement elements by a the sole-side transverse axis engaging behind hooks one hand and a stop engageable in abutment with the sole-side projection on the other hand formed. The binding-side stop is mounted longitudinally displaceable and coupled to the binding-side actuating member such that it by this from a shoe release Position, ie a position out of engagement with the sole projection, in a shoe closing position, ie a position in contact with the sole projection, and vice versa brought, namely displaced.

In a further preferred constructive embodiment of the binding-side stop is an upwardly bent portion of a metal strip which is longitudinally displaceably mounted between the cheeks of the rear and front pivot bearing, and whose front end comprises a U-shaped bent, in particular downwardly open portion, in a cam pin of the actuator engages, so that upon actuation of the actuator by the mentioned driving pin the stop either forward (shoe release position) or to the rear (S chuhschUeß position) is moved.

In order to keep the binding-side abutment in position within the binding housing, the latter has a section with an elongated hole extending in the ski or binding longitudinal direction, through which the articulation axis or horizontal axis assigned to the front or, in particular, rear pivot bearing extends. Through this slot, the binding-side stop or the associated metal strip is held within the binding housing. At the same time, the aforementioned slot defines the limitation of the movement of the stop forward and backward.

In an advantageous embodiment, the slot-shaped section is formed by two lateral, upwardly curved cheeks of the metal strip which embraces the stop. The metal strip therefore has a U-shaped cross section, at least in the middle section. The rear part is defined by the upwardly bent portion and the front part by the U-shaped bent portion.

The binding housing, in particular its bottom plate, comprises at its underside at least one longitudinal rail profile which corresponds to a longitudinal rail at the top of the ski such that the binding housing is held longitudinally displaceable on the ski. Preferably, the two longitudinal edges of the binding housing or the bottom plate of the same on the underside of a U-shaped profiling, which is in each case open towards the inside. This profiling serves to accommodate corresponding rail sections or longitudinal webs. The bottom plate of the binding housing may be extended rearwardly beyond the housing to form a treading and rolling plate with sole longitudinal guide ribs and / or grooves.

A preferred embodiment of a binding formed according to the invention is explained in more detail below with reference to the attached drawing. Show it:

FIGS. 1, 2 and 4-7 show a cross-country or telemark binding 10 for a shoe 11 in side view (FIG. 2) and top view (FIG. 1) and in longitudinal section, which are on the top surface of a ski (not shown) can be mounted. With reference to Figures 4 and 5, the sole 12 of the shoe 11 at a distance from the front sole end 13, in particular in front of the so-called metatarsophalangeal zone 14, a sole-side engagement element in the form of a longitudinal recess arranged in a longitudinal horizontal axis 15, which with a complementary binding side Engagement element, in particular engaging hooks 16 cooperates such that the shoe heel is freely raised, as can be seen Fig. 5. The binding-side engagement element 16 is defined by a U-shaped rigid bracket made of light metal, stainless steel or plastic, whose forwardly projecting legs are pivotally mounted at their front free ends about a horizontal transverse axis 18. Accordingly, the connection-side engagement element 16 is pivotable about the axis 18. bar, against the action of an elastic element, here in the form of two each one leg 17 of the binding-side engagement elements 16 associated helical compression springs 19, which are arranged within a cylindrical housing. For this purpose, the two legs 17 of the binding-side engagement elements 16 (see also Fig. 1) each about the pivot axis 18 upwardly and forward protruding extensions 20, between which on the one hand and the binding housing on the other hand, the helical compression springs 19 are clamped. The projections 20 are in the illustrated imple mentation shape approximately L-shaped with the one leg about the pivot axis 18 upwardly projecting and with the other leg forward into the respective helical compression spring protruding (see, for example, also Figures 6 and 7).

The helical compression springs 19 are used to return the binding-side engagement element 16 in a position approximately parallel to the ski deck according to Figures 2, 4, 6 and 7. They replace the known "flexor" fertilize in conventional Cross-country between the front sole end on the one hand and The shoe 11 or its heel is thus raised counter to the action of the helical compression spring 19 according to FIG.

At the rear end, the connection-side engaging element 16 has an open towards the front engagement hook 21, the element with the sole side engagement 15, which is in the form of a transverse axis, according to the figures 4 and 5 can be brought into engagement. This engagement is made when entering the binding by the user when entering the transverse axis 15 pushes under the engagement hooks 21, and then make the fixation of the shoe, as will be explained below.

As shown in FIGS. 4 and 5, between the sole-side engagement element 15 and the front sole end 13 of the sole 12 there is formed on the sole side a jump 22 which can be brought into contact with a binding-side stop 23 (see FIGS. 4 and 5). that the shoe is held in engagement with the binding-side engagement element 15 and at the same time permits a rocking movement (see double-headed arrow 24 in FIG. 5) about an imaginary transverse axis behind the stop 23 or sole-side projection 22. The sole-side projection 22 comprises a transverse web which is embedded in the sole material and is preferably connected in one piece with the transverse axis 15.

According to FIGS. 6 and 7, the binding-side stop 23 is mounted so as to be longitudinally displaceable (see parts 27, 28) and can be moved, by means of an actuating device with actuating lever 25 and over-center mechanism 29, from a front shoe according to FIG. Freigäbe- or entry position in accordance with FIG. 6 rear closing position and vice versa movable.

The sole-side projection 22 associated abutment surface 30 of the binding-stop 23 is designed and dimensioned so that when lifting and lowering the shoe heel of the sole-side projection 22 without forcing along this stop surface up and is moved. 4, the sole-side projection 22 is at the upper end of the abutment surface 30, where there is still a rearwardly extending limiting lug 26, wherein when lifting the shoe heel this projection 22 along the abutment surface 30 moves down into a position accordingly Fig. 5. In order to reduce the friction between the projection 22 and stop surface 30, the stop surface 30 may be coated with a low-friction plastic (Teflon®). Alternatively, it is also conceivable that the sole-side projection 22 at the front end comprises a rotatably mounted sleeve. The abutment surface 30 of the binding-side stop 23 is in any case processed in a special way, in particular hardened.

The distance between the sole side engaging element or the transverse axis 15 and the sole side projection 22 and the front end thereof is about 15 to 25 mm, in particular about 20 mm. The distance between the front sole end 13 and the sole-side projection 22 is about 10 mm.

The binding 10 comprises a binding housing 31 which is usually made of plastic and in which the binding-side engagement elements 16, 23 which can be brought into operative engagement with the sole-side engagement elements 15, 20 of the boot 11 are movably mounted. The latter associated bearings are held on a fixed in the binding housing 31, in particular on the underside of a binding housing associated bottom plate 32 mounting plate 33, which is preferably a metal plate held. As already mentioned, the binding housing 31, at least its bottom plate 32 is made of plastic. The mounting plate is molded or embedded in the latter from the bottom of the bottom plate 32 and thus firmly anchored. The anchoring is carried out such that the mounting plate 33 with the underside of the binding housing 31 and the bottom plate 32 thereof is flush (see Figures 4 to 7). The above-mentioned bearings include pivot bearings 34, 35 having upstanding cheeks 36, 37, 38, 39 for receiving hinge shafts 18, 40, said cheeks extending through the bottom plate 32 of the binding housing 31 into the interior thereof. In the bottom plate 32 corresponding passage openings for the cheeks 36, 37, 38, 39 are formed, as shown in FIG. 3 reveals.

The mounting plate 33 may also be glued to the underside of the bottom plate 32. However, in terms of manufacture and also with regard to strength, it is preferred if the mounting plate 33 is embedded, in particular cast, within the bottom plate from the underside of the same in the material. An attachment of the mounting plate 13 together with pivot bearing cheeks 36-39 by means of screws or rivets deleted in the illustrated embodiment.

Two front, one front pivot bearing 34 and two rear, a rear pivot bearing 35 defining cheeks 36, 37 and 38, 39 are held in the illustrated embodiment by a common mounting plate 33. In principle, it is also conceivable to assign each of the front and rear cheeks a separate mounting plate.

Both the front pivot bearing 34 and the rear pivot bearing 35 comprises a transversely to the ski or binding longitudinal direction extending horizontal axis 40 and 18, wherein about the rear horizontal axis 18, the sole-engaging member 16 is pivotally mounted, while about the front horizontal axis 40 of Operating lever 25 is pivotally mounted. The binding-side actuator 25, which is pivotally mounted about the axis 40, is coupled to the binding-side stopper 23 such that by actuation of the actuating lever 25, the stop 23 in the direction of arrow 27 or arrow 28 can be moved according to the figures 6 and 7 , In Fig. 7, the stopper 23 is in shoe release position, i. in a position out of engagement with the sole projection 22. In Fig. 6, the stopper 23 is shown in the shoe closed position, i. in a position in contact with the sole projection 22. By the actuating lever 25, the stop 23 can be brought into these two positions.

The binding-side stopper 23 in the illustrated embodiment is an upwardly bent portion of a metal strip 41 which is slidably supported longitudinally between the cheeks 36, 37 and 38, 39 of the front and rear pivot bearings 34, 35 and whose front end is a U -shaped curved, downwardly open portion 42 includes, in which a driving pin 43 or a corresponding driving axis of the actuating lever 25 engages. In the closed position according to FIG. 6, the driving pin 43 is located in a position below the connecting line between the front

Joint axis 40 and rear hinge axis 18, and thus in an over-center position (over-center mechanism 29). Once by means of the operating lever 25 of Mitnehmerzapfen 43 exercises these connecting lines moved up wkd, the stop 23 can easily move into the shoe release position corresponding to Fig. 7.

The metal strip 41 comprises between the rear, the stop 23 defining part and the front U-shaped bent engagement member 42 has a central portion with two laterally upwardly bent longitudinal cheeks 44, in each of which an extending in ski or binding longitudinal slot 45 is formed through which the rear pivot bearing 35 associated hinge axis 18 extends therethrough. Thus, the metal strip 41 together with stop 23 is held in the binding housing 31. At the same time, the front and rear limits of the slots 45 serve as a stop for the longitudinal movement of the sole-side projection 22 associated stop 23rd

According to FIG. 3, the mounting plate 33 also has a plurality of circular recesses 46, which are filled with the material of the base plate, whereby the anchoring between the base plate and the mounting plate is increased.

The bottom plate 32 is extended according to the figures 1 to 7 on the binding housing 31 out to the rear and has on its surface two longitudinal guide ribs 47.

Furthermore, U-shaped profiled strips 48 are integrally formed on the two longitudinal edges of the bottom plate, engage in the complementary transverse webs of a binding mounting plate on the top of a ski such that the binding 10 is mounted longitudinally displaceable on the ski. The profiled strips 48 are each open at the mutually facing sides, so that corresponding longitudinal grooves are defined.
