DETAILED DESCRIPTION

(14) A ski 1 can be seen in FIG. 1, on which a slide rail or binding plate 2 is arranged. Slide rail 2 is screwed and/or glued to ski 1 or can be constituted in one piece with an upper laminate of ski 1.

(15) In the example of embodiment shown, a latching element 3 constituted separate from slide rail or binding plate 2 is provided in the form of a latching rail or engagement rail 3′, which comprises a multiplicity of receiving openings 4 constituted essentially cylindrical. Latching rail 3′ is accommodated in a recess of slide rail 2 and—separate from slide rail 2—is connected, in particular glued and/or screwed, to ski 1.

(16) Slide rail 2 comprises slide rails 2′ which project at the longitudinal edges, in a manner known per se, and which, for the displaceable mounting of a binding element 5, are accommodated in groove-shaped depressions 6 of binding element 5 (see FIG. 3), when binding element 5 is pushed onto slide rail 2.

(17) Binding element 5 in a position pushed onto slide rail 2 is then shown in FIG. 2, wherein it can be seen that binding element 5 comprises two viewing windows 7, through which a view of a position indicator 8 on the upper side of the slide rail 2 is possible.

(18) Furthermore, it can be seen that binding element 5 comprises in the front end section two hook-shaped holding elements 9 for use as a cross-country binding or telemark binding, which holding elements are provided for receiving a pivot axle of a ski boot. In the position fastened on binding element 2, therefore, a ski boot, in particular a cross-country or telemark boot, is mounted pivotable about the pivot axle accommodated in holding elements 9.

(19) In particular in FIGS. 4 and 5, an operating element 10 can also be seen, which is arranged in a closed position, in which a latching element 11, which can be actuated by operating element 10, is arranged in its blocking position. Operating element 10 is mounted, in particular displaceably, between the closed position and an open position (see FIG. 9) in a recess 13 in a plate-shaped base element 17 of binding element 5. For this purpose, recess 13 comprises laterally projecting guide webs 13′, on which the operating element is mounted displaceably with lateral webs 10″ (see FIG. 10B), wherein—as can also be seen in FIG. 9—operating element 10 in the open position is also pivoted slightly by the elastic restoring force of lever element 12.

(20) As can be seen in particular in FIG. 6, a lever element 12 is provided as a binding-side latching element 11, which lever element 12 is arranged in a blocking position or latching position in such a way that latching pins 12″ connected to a lever arm 12′ are received in corresponding receiving openings 4 in latching rail 3′, said receiving openings being cylindrical in the example of embodiment shown.

(21) Lever element 12 is positioned here in its relaxed initial position, such that pivoting of lever element 12 out of its relaxed initial position is required for release of lever element 12 out of the blocking position. For this purpose, operating element 10 is provided, with which the lever element 12 can be deflected essentially about a pivot axis 14 (see in particular also FIG. 9).

(22) In the cross-sectional view according to FIG. 6, it can also be seen that operating element 10 is arranged in a latched closed position in the blocking position of lever element 12 shown in FIGS. 3 to 6. Blocking-latching elements 15, 16 are provided for this purpose.

(23) In the example of embodiment shown, a pin-shaped latching element 15′, which is arranged at the underside of essentially plate-shaped base element 17 of binding element 5, and a groove 16′ in operating element 10 are provided as blocking-latching elements 15, 16. Groove 16′ is constituted tapered from an entry opening to a narrow point, which is adjoined in the latched position by a cylindrical latching opening 16″ for receiving pin-shaped latching element 15′. At the transfer over the narrow point, groove 16′ therefore widens elastically, so that in the latching position pin-shaped latching element 15′ then snaps in. When operating element 10 is transferred into the closed position which can be seen in particular in FIG. 5, the reaching of the closed position is therefore audible or perceptible in a tactile manner to the user on account of the snap-in process; the same applies—as is also explained in detail below—to the transfer of operating element 10 into the open position.

(24) It can also be seen in FIG. 4 that operating element 10 comprises a securing section 18 in an end section directed towards lever element 12, which securing section cooperates with a securing section 19 of lever element 12 (see FIG. 10B). Operating element 10 and lever element 12 are constituted in such a way that securing section 18 of operating element 10, in the blocking position shown in FIG. 6, overlaps securing surfaces 19′ (see also FIG. 10B and FIG. 11) of lever element 12 which securing surfaces 19′ project laterally from lever arm 12′ in securing section 19. In the blocking position of operating element 10, therefore, pivoting of lever element 12 into a displacement position, in which latching pin or pins 12″ are released from receiving opening(s) 4, is reliably prevented.

(25) In order to fix operating element 10 in the vertical direction in the closed position, a form-fit groove/spring connection 25, 26 is also provided between operating element 10 and base element 17 in the closed position. In the example of embodiment shown, operating element 10 comprises lateral grooves 25 and recess 13 in base element 17 comprises springs or hold-down webs 26 projecting laterally over a part of the length extension of recess 13. When operating element 10 is transferred into the closed position, hold-down webs 26 projecting laterally into recess 13 are thus each received in grooves 25, so that the vertical position of operating element 10 in its closed position is defined by the form-fit groove/spring connections.

(26) It can be seen in FIGS. 7 to 9 that in particular lever element 12 can be transferred into its displacement position with the aid of operating element 10.

(27) For this purpose, operating element 10 is displaced in the direction of lever element 12, wherein the operating element 10 comprises oblique run-on surfaces 20 at its end section 10′ facing towards lever element 12 (see also FIG. 10A), which run-on surfaces cooperate with lower oblique contact surface 21 of lever element 12, so that operating element 10 in the closed position represented in FIGS. 4 to 6 is released and lever element 12 is pivoted upwards out of the closed position. For easier handling, operating element 10 comprises a depression 27, in which a finger of the user can be accommodated for the purpose of displacing operating element 10.

(28) After lever element 12 has been pivoted upwards out of its essentially relaxed initial position with the aid of end-side run-on surface 20, latching pins 12″ are brought out of engagement with receiving openings 4 of latching rail 3′ by contact surface 21 of lever element 12, the contact surface 21 running onto run-on surface 20 of operating element 10 with further displacement—as can be seen in particular in the intermediate position of operating element 10 shown in FIG. 11, until operating element 10 arrives in the end or open position represented in FIG. 9.

(29) When operating element 10 has reached its end or open position, a web 22′, which is provided at the underside of the front end section of lever element 12, also snaps into a groove-shaped depression 23′ (see FIG. 10A) of operating element 10. By means of this latching connection between web/groove connection 22′, 23′ constituted as displacement-latching elements 22, 23, lever element 12 is thus held in its displacement position, so that the user can easily displace binding element 5 on slide rail 2.

(30) The user can also view through viewing window 7 position indicator 8 fitted on the slide rail and, as soon as the desired position is reached, lever element 12 is again returned into its relaxed initial position by a displacement of operating element 10 into the blocking position shown in particular in FIG. 6, so that latching pins 12 engage in corresponding cylindrical receiving openings 4 in latching rail 3′, so that a displacement of binding element 5 with respect to the slide rail is not possible in the then reached blocking position of lever element 12 or the closed position of operating element 10.

(31) A ski binding that can be operated easily and without tools is thus created with the device according to the invention, with which the position of the ski binding with respect to ski 1 or a slide rail 2 can be changed in a straightforward and easy manner.
