Description

Description Binding arrangement for skis or snow gliding boards

The invention relates to a binding arrangement for ski or snow sliding boards with front or toe and rear or heel-side shoe holders and the shoe holder supporting or abutment parts, which are adjustable relative to a fixed to the ski or snow sliding board basic arrangement in the longitudinal direction of the binding arrangement are arranged.

According to US 3,857,186 can be provided in such binding arrangements that the shoe holder or their support or abutment parts are coupled to each other, such that they can be moved simultaneously in opposite directions to adapt the binding arrangement to shoes of different sizes ,

[003] According to US Pat. No. 3,857,186, the base arrangement is designed as a plate-like, flat, rectangular housing which is mounted on a ski with its closed underside. The top has a window extending in the longitudinal direction of the housing, which serves as a guide for the Tragbzw. Abutment parts of the shoe holder is used, the longitudinal edges of the window can engage in corresponding lateral grooves on the support or abutment parts. For the movement coupling and adjustment of the support or abutment parts or the shoe holder carried by them, a threaded spindle can be provided which is axially immovable but rotatably mounted within the base part and has two threaded sections with opposite thread sense, the one support or abutment part on the one threaded section and the other support or abutment part on the other threaded section is arranged so as to be screw-adjustable.

For the rest, in US 3,857,186 other means for the movement coupling of the shoe holder are specified, for example, rack and pinion gear.

[005] In a binding arrangement known from AT 402900 B with shoe holders that are coupled in a movement-related manner for simulator adjustment, the supporting parts of the shoe holders are designed as slides, which in turn are guided on base plates mounted in a ski-like manner, which for this purpose can have, for example, C-shaped longitudinal edges.

[006] EP 0 857498 B1 describes a binding arrangement primarily intended for snow gliding boards or snowboards. This has a stable base plate which is fastened in a middle section so as to be rotatably adjustable on the upper side of the snow sliding board or snowboard, such that the end regions of the base plate are spaced apart from the upper side of the snow sliding board or snowboard, ie these end areas extend freely above the top of the snowboard or snow gliding board.

On these end areas support or abutment parts are slidably arranged, which in turn serve to hold shoe holders. The support and abutment parts have a tubular configuration encompassing the base plate. According to an embodiment described in EP 0857 498 B1, the supporting or abutment parts can be displaced simultaneously in the longitudinal direction of the base plate by a rotating spindle.

The object of the invention is now to provide a particularly simple construction, in particular with regard to the sliding guide of the support and abutment parts in a binding arrangement of the type specified.

This object is achieved in that the base arrangement in the region of the support or abutment parts as a shell-shaped part open to the top of the ski or snow sliding board and each of the support or abutment parts as between the top of the ski or snow sliding board and the Basic arrangement is slidably arranged in the longitudinal direction, the Tragbzw. Abutment parts are preferably immovable in the transverse direction between the upper side of the ski or snow sliding board and laterally longitudinal edge sections of the base arrangement and immovable in the transverse direction by positive engagement in a guide profile extending in the longitudinal direction of the binding arrangement and directed to the upper side of the ski or snow sliding board.

The invention is based on the general idea of using the top of the ski or snow sliding board essentially directly as a guide element for the vertically immobile guidance of the supporting or abutment parts of the binding arrangement. Here the knowledge is used that skis or snow gliding boards regularly have a strong and resilient structure within the zones provided for the assembly of binding arrangements and accordingly can be used not only as a carrier of guides but also as a guide element.

Due to the open underside of the base arrangement, the support or abutment parts can easily be brought into engagement with the guide profile, so that the entire assembly of the binding arrangement is considerably simplified.

According to a preferred embodiment of the invention, the support or abutment parts can be coupled to one another simultaneously in mutually displaceable directions, preferably by means of a threaded spindle with a right-handed threaded section assigned to one support or abutment part and another to the other support or Left-handed thread section assigned to abutment part.

[013] It is particularly expedient here that the support or counter bearing parts screwed threaded spindle is essentially only radially supported in the threaded parts. This offers the possibility of inserting the threaded spindle after screwing into the threaded parts of the support and abutment parts from the open underside of the base arrangement in axial bearings on the base arrangement and securing them by snapping between two bending legs on the base arrangement in the axial bearings. So here the support or abutment parts with the threaded spindle form a preassembled module that can be completely inserted into the basic arrangement.

The connection between the threaded parts of the support or abutment parts and the threaded spindle is self-locking in conventional thread pitches, i. H. the supporting or abutment parts can only be adjusted on the spindle by means of torques exerted directly on the spindle, for example using a tool.

To avoid an unwanted adjustment can be provided in an advantageous embodiment of the invention that the threaded spindle has a locking wheel with a plurality of circumferential locking recesses which cooperate with a locking element arranged on the base arrangement, for example with a leaf spring-like locking element attached to the base arrangement.

One shoe holder is preferably designed as a C-shaped bracket, which overlaps and encompasses a front part or sole edge of the shoe, and whose C-ends encompass the lateral longitudinal edge sections of the base arrangement on a support or abutment part in the transverse direction and are rotatably supported in transverse grooves open to the longitudinal edge sections on a support or abutment part.

The other, arbitrarily lockable or unlockable shoe holder is preferably arranged on a cranked central region of a further C-bracket, the C-ends of which encompass the lateral longitudinal edge sections of the base arrangement on the other support or abutment part in the transverse direction and in to the aforementioned Longitudinal edge sections open transverse grooves are rotatably mounted on the other support or abutment part.

In these embodiments, the basic arrangement with its longitudinal edge sections also serves to hold the C-frame on the supporting or abutment parts. At the same time, assembly is much easier.

[019] The further shoe holder can have a part which is rotatably mounted on the further C-bar and which is provided with large openings for pushing through the further C-bar, which in an assembly position of the shoe holder part on the C-bar for play-free radial mounting of the shoe holder part on the C- Brackets can be downsized by insert or fitting.

In particular, it can be provided here that the adapters can be used on the inside of the large openings in the side cheeks of the shoe holder part and in the shoe holder's positions of use through the offset adjacent to the inner sides are secured.

For the rest, with regard to preferred features, reference is made to the claims and the drawing, on the basis of which particularly preferred variants of the invention are described in more detail. The scope of protection is not limited to the expressly described or illustrated combinations of features. Rather, protection is also claimed for basically any sub-combination of the features.

1, 2 and 4, a base plate arrangement 2 is fixedly arranged on a ski 1, in particular a short ski, which is only partially indicated in FIG. 2, wherein screws (not shown) which are screwed into the ski can serve for fastening, which are inserted into corresponding receiving holes 3 (see FIG. 1) of the base plate arrangement 2. The top of the base plate arrangement has front and rear treads 2 ′ and 2 ″, which serve as a contact surface for a front and rear sole area of a ski shoe 4 to be inserted into the binding arrangement, which is indicated by dashed lines in FIG. 2 The front shoe holder 5 and a lockable rear shoe holder 7 held on a further bracket 6 The front bow-shaped shoe holder 5 engages over the front sole edge, while at the same time engaging around the front shoe cap at the same time the sole edge and / or the grips the shells of the shoe. As will be shown below, the rear shoe holder 7 can be manually adjusted to exit the binding into the position of FIG. 3, from which the shoe holder 7 automatically turns into the locked use position of FIG. 2 when the shoe 4 is in the binding is used, that is, the rear shoe holder 7 has a so-called step-in locking. The bow-shaped front shoe holder 5 and the bracket 6 of the rear shoe holder 7 are each held on abutment parts 8 and 9, which are arranged to adjust the binding arrangement to different shoe sole lengths in the longitudinal direction of the ski 1 or the binding arrangement, as also more precisely below is pictured.

[036] The base plate arrangement 2 is designed as a shell arrangement which is open to the upper side of the ski 1, the edge of the shell resting firmly on the upper side of the ski when the base plate arrangement 2 is mounted on the ski 1. Front and rear windows 10 and 11 are recessed within the edge of the shell, through which the front and rear abutment parts 8 and 9, which are otherwise located below the base plate arrangement 2 in the interior of the shell, protrude laterally.

The longitudinal edges of the windows 10 and 11 together with the top of the ski form a vertical guide for the parts of the abutment parts 8 and 9 passing through the windows, so that the abutment parts 8 and 9 are held in the vertical direction.

On the inside of the shell formed by the base plate arrangement 2, parallel longitudinal webs 12 are arranged according to FIG. 7, which overlap cheeks 13 formed on the abutment parts 8 and 9 and parallel to the longitudinal webs 12, such that the abutment parts 8 and 9 also be held in the transverse direction of the ski 1 or the binding arrangement.

For the sliding adjustment of the abutment parts 8 and 9, a threaded spindle 14 visible in FIGS. 2 and 4 is used with a front threaded section which is assigned to the front abutment part 8 and a rear threaded section which is assigned to the abutment part 9. These thread sections have opposite thread sense, that is, one thread is right-handed and the other left-handed. With these threaded sections, the threaded spindle 14 is screwed into corresponding counter-threaded parts on the abutment parts 8 and 9. The arrangement or attachment of these counter-thread parts is explained below. The threaded spindle 17 has ring webs 15 arranged between the threaded sections, which cooperate with the transverse webs formed on the inner shell side of the base plate arrangement 2 for the axial mounting of the threaded spindle 14.

In order to be able to ensure that the threaded spindle 14 remains connected to the base plate arrangement 2 when it is separated from the ski 1, the left end of the threaded spindle 14 in FIGS. 2 and 4 projects into a pocket-like recess on Front area of the base plate arrangement 2. Otherwise, the threaded spindle 14 is locked with its central region between spring cheeks 16, which are integrally formed on the base plate arrangement 2 and encompass the circumference of the threaded spindle 14 in a resiliently spreading manner.

The radial bearing of the threaded spindle 14 is taken over by the counter-thread parts on the abutment parts 8 and 9.

A cross-head or the like is arranged at the right end of the threaded spindle 14 in FIGS. 2 and 4, into which a corresponding screwing tool can be inserted in order to be able to turn the threaded spindle, the abutment parts 8 and 9 each move towards or away from each other according to the direction of rotation of the spindle 14.

The threaded spindle 14 is held in the counter-threaded parts of the abutment parts 8 and 9 by self-locking in the respective rotational position. In addition, a locking wheel 17 is arranged or formed on the rotary spindle 14 in a rotationally fixed manner, which has a circumference with a large number of locking recesses which cooperate with a locking spring (not shown) on the base plate arrangement 2. This locking spring rod can have, for example, the shape of a leaf spring with a bead serving as a locking lug. Thus, the threaded spindle 14 is automatically locked in closely adjacent rotational positions.

The abutment parts 8 and 9 and the mounting of the brackets 5 and 6 on the abutment parts 8 and 9 are basically of the same design, wherein they are structurally essentially symmetrical with respect to a vertical transverse plane of the binding arrangement. In the following, only the abutment part 9 is explained in more detail with reference to FIGS. 5 to 8.

[045] sideways of the cheeks 13 has, the abutment member 9 relatively flat, resting on the ski upper side arms 18, is formed in plan view as Z _^ shaped trough 19 on the upper side, the central portion thereof is in each case extends in Queirichtung. One end section of each trough extends parallel to the facing flank 13. The other end section is formed parallel to the flanks 13 within the end region of the respective arm 18.

The central portions of the trough 19 extending in the transverse direction of the binding arrangement serve as a bearing bed for the transversely extending ends 6 'of the bracket 6 (cf. FIG. 9), with the end parts 6' of the bracket 6 emerging from the troughs 19 through the Longitudinal edges of the window 11 of the base plate assembly 2 is prevented, that is, between the longitudinal edges of the window 11 and the troughs 19, the end parts 6 'of the bracket 6 are held without radial play.

The end parts 6 'of the bracket 6 have angled free ends which bear resiliently on the cheeks 13 of the abutment part 9. If the bracket 6 between the in Fig. 2 and 4 pivoted positions, the angled ends on vertical, web-like projections 20, which are formed on the cheeks 13, slightly spread, so that a pressure point must be overcome during the pivoting movement of the bracket.

Otherwise, the swivel positions of the bracket 6 shown in FIGS. 2 and 4 are designed as end positions. This is achieved in that the legs of the bracket 6 in the position of FIG. 2 rest on ramps (cf. FIG. 2) which are formed at the ends of the arms 18 of the abutment part 9 in the region of the troughs 19 extending there in the longitudinal direction , The end position of FIG. 4 is predetermined in that the angled ends of the end parts 6 ′ rest on the bottom of the parts of the troughs 19 that extend along the cheeks 13.

On the abutment part 9, a downwardly open pocket 21 is formed, into which a nut 22 can be inserted from below (see FIG. 8), which serves as a counter-thread part for the associated threaded section of the threaded spindle 14 and can be rotated in the aforementioned pocket 21 and is held axially immovable.

[050] The bow 6 has a crank 6 "in its central section, to which sections 6 '" are connected. These serve as the bearing axis for the rear shoe holder 7.

2 and 3, the rear shoe holder 7 has a shoe holder part 7 'which interacts with the ski boot 4 and a handle part 7''pivotably connected to it about an axis 23. The axis 23 also supports a leg spring 24 which holds the handle part 7 "relative to the shoe holder part 7 ^* in FIG. 2 seeks to pivot counterclockwise.

[052] The shoe holder part 7 'is rotatably mounted at a distance from the axis 23 on the sections 6' "of the bracket 6. The handle part 7" interacts with the offset 6 "of the bracket 6. For this purpose there is a nose 25 on the handle part 7" 2, which overlaps the offset 6 "in the position of the shoe holder 7 shown in FIG. 2 such that the offset 6" is completely received in a bay 26 formed in the handle part 7 "next to the nose 25 2, the shoe holder part 7 'is locked, that is to say locked against rotation relative to the bracket 6 in a clockwise direction, because the handle part 7 "cannot be dragged along by the shoe holder part 7' in the sense of a clockwise rotation relative to the bracket 6. This is based on the fact that the nose 25 of the handle part 7 "in FIG. 2 assumes an over-center position with respect to the crank 6".

If the handle part 7 ″ is now manually adjusted clockwise from the position in FIG. 2, it can be tilted into the position in FIG. 3 in which the shoe holder part 7 ′ is taken into a position releasing the shoe 4 , The position of the shoe holder in Fig. 3 is self-retaining, because the nose 25 of the handle part 7 "of the Leg spring 24 is held in an over-center position with respect to the crank 6 ".

When the shoe holder 7 assumes the position of FIG. 3 and the shoe 4 is inserted into the binding, a step spur 27 formed on the shoe holder part T is depressed, so that the shoe holder part T is pivoted counterclockwise from the position of FIG. 3 is, the handle part 7 "is pivoted and snaps under the force of the leg spring 24 in the position of FIG. 2, in which the shoe holder part 7 'is locked and overlaps the rear edge of the sole of the ski shoe 4 with an edge 28.

[055] In order to be able to arrange the shoe holder part 7 on the bracket 6, large windows 29 are arranged on the shoe holder part 7 'for the passage of the bracket 6. 11 and 12, which is provided as a storage bed for the sections 6 '"of the bracket. In order to hold the sections 6'" of the bracket 6 in the above-mentioned bays of the windows 29, a bay is formed thereon insert fillers 30 into the windows 29, specifically from the inside of the side walls of the shoe holder part 7 '. After assembly of the handle part 7 "on the shoe holder part 7 ', these filler pieces are fixed captively by the handle part 7".

The bracket 5 is arranged in principle in the same way on the abutment part 8 as was described for the arrangement of the bracket 6 on the abutment part 9. Otherwise, the abutment part 8 also has a pocket for receiving a nut 22 serving as a counter-thread part. Unrecognized text
