Description

The invention relates to a touring, telemark or cross-country binding, with a mountable on a ski or the like Schneegleitgerät housing in which a with a sole side engaging element, in particular an engagement axis of a shoe, engageable in operative connection-side engagement member is movably mounted.

In addition, the present invention relates to a method for mounting a ski binding according to the aforementioned type.

Such a bond is well known. It comprises engagement elements which can be brought into engagement with complementary engagement elements on the sole of a ski boot in such a way that the heel of the shoe can be lifted freely. It is only exemplary in this respect to the DE 10 2005 026 725 A1 . DE 36343 203 A1 . WO 01/93963 A1 , or the EP 1 226 850 B1 partially attributed to the applicant. The present invention is also intended to refer to bindings which are longitudinally slidably mountable on top of a ski.

The invention is based on the cited prior art, the object to provide a bond available, which is characterized by the ease of manufacture and in particular by a simple assembly. In particular, the bond should be assembled without any screw and separate hinge axes. This object is achieved by the characterizing features of claim 1, wherein further details and constructive embodiments are described in the subclaims.

In particular, this object is thus achieved by a ski binding, in particular touring, telemark or cross-country binding, mounted with a mountable on a ski or the like Schneegleitgerät housing in which a with a sole side engaging element, in particular engagement axis of a shoe, engageable engageable binding side engagement member wherein the binding-side engagement member includes a longitudinally displaceably mounted in the housing and hineinbewegbaren in closed position in an upwardly open manhole for the sole side engaging member engaging hook or strap, wherein the engagement bracket opposite end of the binding-side engagement element via an insertable from the top of the binding housing coupling element with an actuating member, in particular actuating lever is connectable.

By insertable from the top of the binding housing coupling element is a very simple connection between the actuating lever and the longitudinally displaceably mounted in the housing connection-side engagement element is possible, which significantly reduces the assembly time. Also, the formation of this 3-component "locking mechanism" simplifies the binding structure, which reduces the susceptibility to errors and saves costs.

The engagement bow opposite facing, front of the manhole in the binding housing is formed by an insertable from the bottom of the binding housing ago bearing plate made of metal or the like abrasion resistant material. Since the binding housing is mounted on the ski or Schneegleitgerät after the final assembly of the binding, the above-described embodiment of the manhole by a insertable from the bottom of the binding housing forth bearing plate made of metal or the like abrasion resistant material guarantees a secure fixation thereof in the housing and beyond the very simple and especially on screws or similar fasteners waiving attachment.

Preferably, the bearing plate delimiting the front side of the manhole opening has a passage opening and in particular a transverse slot, through which the connection-side engagement element is longitudinally displaceably mounted. In this way, a fixation of the longitudinally displaceable binding-side engaging element is achieved substantially perpendicular to the binding housing, which in turn can be dispensed with additional fastening means. The transverse slot or the passage opening is preferably adapted to the cross-sectional dimension of the engagement element or designed to be complementary thereto. In particular, it is designed so that a longitudinal displacement ensured, but a displacement in the transverse direction or in a direction perpendicular to the housing is prevented. However, it is important to ensure that the transverse slot is formed so that the engaging element during assembly of the ski binding through the transverse slot can be "threaded" and also possibly and hereinafter described in more detail projections or projections through the transverse slot can be performed.

Preferably, the bearing plate limiting the front side of the manhole is part, in particular the upright middle web of a T-shaped profile. Since, as mentioned earlier, the bearing plate is inserted from the underside of the binding housing, this T-shaped design guarantees a secure fit of the bearing plate in the binding housing. In particular after assembly of the assembled ski binding on the snow gliding device, a secure fit within the ski binding is ensured by this T-shaped profile.

Preferably, the engagement bracket of the binding-side engagement member is part of a strip-shaped plate of metal or the like resistant material, the front, the engagement bracket opposite transverse edge has an upwardly bent portion to which the coupling element is plugged for the purpose of coupling, so that this together with the engagement bracket or to this comprehensive engagement element back and forth. This design guarantees a very inexpensive production and beyond the very simple installation of the coupling element on the binding side engagement element, without having to resort to additional fasteners, such as screws or adhesives. In principle, it is also possible, instead of the upwardly bent portion of the strip-shaped Plate of the binding-side engagement member to form a corresponding receptacle into which then a corresponding extension of the coupling element can be coupled, latched, etc. Here are all known from the prior art method for connecting or coupling two elements without the use of additional connecting means applicable.

Preferably, the coupling element has a recess extending transversely to the binding longitudinal direction, in particular transverse groove into which protrudes extending extension beyond a pivot axis of the actuating element facing the coupling element, so that by pivoting the actuating lever forward or rearward the coupling element together with coupled binding-side engagement element within the binding housing back and forth and is in and out of the closed position. In this case, this, in particular "eccentric" extension is formed so that preferably the actuating lever in the closed position, ie in the position in which he urges the coupling element and the coupling-side engaging element or its engagement bracket coupled to the bearing plate or a fixed fixation guaranteed between engaging bracket and bearing plate, aligned substantially horizontally and parallel to the binding housing. Of course, it is also possible to perform corresponding coupling recesses on the coupling element, in which then engages over the pivot axis of the actuating lever protruding extension by being formed with corresponding latching projections, which engage in the locking receptacles and allow simultaneous pivoting of the coupling element during pivoting.

Preferably, the pivot axis of the actuating lever is formed by two diametrically extending pivot pins which are held in the binding housing between the coupling element on the one hand and the housing, inwardly projecting housing projections on the other hand. The pivot pin or the housing projections are preferably formed integrally with the actuating lever or the housing. In particular, the housing protrusions are formed from an elastic material, so that a secure engagement of the pivot pin on the housing protrusions is possible. Since just the case is usually made of a plastic material is the formation of these integral housing protrusions very inexpensive and reliable.

Preferably, the free end faces of the pivot pin of the actuating lever are bevelled in the direction away from the handle end inwardly, so that they can be brought into pivoting position with relatively little effort under lateral spreading of the pivot pin cross housing projections to the outside. This design allows the simple Eisnetzen of the actuating lever in its holder on the housing and the simultaneous inexpensive formation of the pivot axis for pivoting the actuating lever without the use of additional screws or axle elements.

Preferably, the pivot projections cross housing projections are part of the housing side wall, which reduces the structure of the individual binding parts and their production and the space requirement of the entire bond.

In principle, therefore, a ski binding is presented by the present device, which can be assembled very easily and without any use of additional screws, rivets or similar fasteners and axle. This guarantees, among other things, a low-cost production, a very easy and quick installation and, moreover, a very user-friendly system in use. For example, it is possible for a cross-country skier to very easily disassemble and clean an iced or dirty bond. Since all the elements can be adapted to each other and coupled with each other by snap-in or plug-in connections, the weight is reduced, since no additional mounting elements are necessary.

The above object we solved in addition to a ski binding by a method for mounting a ski binding, in particular a ski binding according to one of the aforementioned embodiments, namely, starting from a binding housing first from below, especially the front of an upper manhole for a Sohlenseitiges engagement element of a shoe limiting bearing plate made of metal or the like abrasion resistant material is inserted, then from behind the binding side engagement member is inserted with engagement bracket so that it with its the engagement bracket opposite transverse edge through an opening in the Front side of the entry opening limiting bearing plate can be passed, so that the engagement bracket faces with its open end of the bearing plate, and that in turn inserted from above a coupling element between bondungsseitigem engagement element and an actuating lever, in particular attached to the binding side engagement member, wherein ultimately the coupling element is held within the binding housing by the latching into this actuating lever.

By previously mentioned method, it is possible to mount or assemble a ski binding so that no further fastening and mounting elements, such as screws, rivets, adhesives, etc., has to be resorted to. This reduces installation costs, assembly time and simplifies the assembly process.

Further embodiments of the invention will become apparent from the dependent claims.

In the following, the same reference numerals will be used for the same and the same parts, sometimes with reference to indicated reference numerals find their use.

Fig. 1 shows an exploded longitudinal section through an embodiment of the ski binding according to the invention, which is designed here as a cross-country binding 10. The same embodiment is also in the Fig. 2 to Fig. 4 shown as a longitudinal as well as a cross section and plan view. Shown are in addition to the individual components of the ski binding 10 and direction arrows that illustrate the insertion movement of the individual components of the ski binding 10 during their assembly. In addition, by the circled numbers 1 to 4 in Fig. 1 schematic of each assembly step 1-4 of this assembly process or assembly process shown.

The ski binding 10 has a housing 11, via which the ski binding 10 is mounted on a snow gliding device, here for example a cross-country ski (not shown), and which in turn receives the individual components of the ski binding 10. According to the invention, no additional connecting elements, such as screws, adhesives or additional axle elements are necessary in the completion of the individual components of the ski binding 10.

The housing 11 of the ski binding 10 is preferably made of a plastic material, which is produced in particular by means of injection molding. It also has corresponding grooves and receptacles to, as will be explained below, the individual components of the ski binding 10 record.

At the beginning of the assembly process (assembly step 1) of the ski binding 10 from the bottom 40 of the housing 11, a T-shaped profile 19 is inserted from below (arrow 34) into the housing 11 that it protrudes on a top 42 with a bearing plate 17 , This bearing plate 17 forms with mounted binding 10 part of a manhole 13, in which an engagement axis 50 or a similar engagement element of a cross-country boot (not shown) can be used (see in particular Fig. 2 ).

The bearing plate 17 has an opening or a transverse slot 18, through which in a further assembly step (assembly step 2) a binding-side engagement element 12 can subsequently be carried out from behind (arrow 35). This binding-side engaging element 12 is adapted to a corresponding guide on the housing 11, that it is mounted longitudinally displaceable in the housing 11. It comprises an engagement hook or engagement bow 14, which is designed such that it can be moved into the upwardly open access opening 13 by the longitudinal displacement along the direction of the arrow 35. On this way embraces, as in Fig. 2 shown, this engaging bracket 14, the engagement axis 50 of the shoe (not shown) and forms together with the position plate 17 a hinge bearing over which the shoe is pivotally fixed to the ski binding 10.

The binding-side engaging element 12 is here designed as a strip-shaped plate 20, on whose front transverse edge 21 opposite the engaging clip an upwardly bent section 22 is formed. In this upward bent portion 22, a coupling element 15 from above (arrow 36) is now placed and coupled in the assembly of the ski binding 10 in a third assembly step (assembly step 3). In this way, in a longitudinal displacement (arrow 35) of the binding-side engagement element 12 parallel to the housing 10 and the coupling element 15 moves.

In a fourth assembly step (assembly step 4), an actuating lever 16 from above (arrow 36) is now inserted into the ski binding 10. The storage necessary for insertion is provided by the housing 11 of the ski binding 10 available. For this purpose, in particular on the housing walls 32, 33 housing projections 27, 27 ', 27 "are provided, the correspondingly complementarily designed pivot pin 25, 26 engage around so that a stationary pivoting of the actuating lever 16 about an axis 24 thus formed is possible.

At the pivot pins 25, 26 of the actuating lever 16, free end faces 28, 29 are chamfered away from the handle end 30 in one direction, so that insertion into the bearing formed by the housing projections 27, 27 ', 27 "is facilitated by these chamfered end faces 28 29, the housing projections 27, 27 'are forced in a lateral direction (arrow 31) until they then engage around the pivot pins 25, 26.

The actuating lever 16 has, in addition to the pivot pins 25, 26 at least one extension 24a, which is formed eccentrically to the pivot axis 24. This extension 24 engages in a transverse groove 23 on the coupling element 15, so that this when reciprocating the actuating lever 16 and with this coupled thereto the engagement element 12 reciprocated. The coupling element 15 has in this case two detent positions within the transverse groove 23, the actuating lever 16 via the extension formed thereon 24a both in the closed position (see Fig. 2 ) as well as in the open position (see Fig. 3 ) lock in place.

As a result of the connection between the actuating lever 16, extension 24a, coupling element 15 and längsverschieblichem engagement member 12 so the gift of the operating lever 16 has an opening and closing of the manhole 13 result (see Fig. 2 and Fig. 3 ).

In order to additionally guarantee a fixation of the longitudinally displaceable engagement element 12, the housing 11 of the binding 10 further has a clamping extension 44. Between this clamping extension 44 and the longitudinally displaceable engagement element 12, a flexor 46 is used in this embodiment, which due to its elastic design u.a. guarantees a secure fixation of the binding elements.
