In this way, the design is maintained flat and the spring travel is long and spring fore can be optimally adjusted. Insertion of the foot in the binding is also facilitated and the stability of the ski boot (9) around its vertical axis is good and the binding grips without and play. With this design numerous advantageous embodiments of the biding are possible.

Description

The invention relates to a ski binding-ski boot combination for cross-country skis, with a first binding unit permanently attached to the ski and a second binding unit which forms part of the ski boot, two axes being arranged parallel to one another and transversely to the longitudinal direction of the ski, one of which is at least in Direction perpendicular to the ski is held in an axle mount and the other is loaded by at least one spring element, so that the ski boot is held resiliently on the ski.

A ski binding of this type is known, for example, from DE-C-29 54 446 as well as from numerous specimens which act on a similar principle and are available from specialist dealers. What they have in common is that an axle molded onto the tip of the ski shoe is releasably inserted into an axle receptacle on the other binding unit, so that the ski boot is pivoted about this axis due to the cross-country movement. The desired springback of the ski boot on the ski is achieved in these ski bindings in that the force of a spring element above this axis and axle support presses on the front part, ie the tip of the ski boot. The shape of the tip of the ski boot is adapted to absorb the spring pressure. In order to avoid a direct action of the spring element or a body transmitting the spring force on the ski shoe, or its sole extension that runs out upwards, the axis of the ski shoe is provided with an upwardly directed offset according to DE-C-29 54 446 that there are two axes running at a short distance from one another, which run cross-offset along mutually parallel geometric axes. Accordingly, the spring element or the spring-loaded transmission body presses on the upper one Axle parts. Since both axle parts are held in the horizontal direction only by the force of the spring element, these can turn together so that the ski boot has little lateral stability to the ski. In addition, this ski binding can only be opened and closed by hand by operating the locking lever. Furthermore, the known spring elements of ski bindings, consisting for example of a rubber block or compressible wire brackets, are substantially limited in their spring travel and have an unfavorable spring characteristic.

The invention has for its object to find an improved ski binding that allows good lateral stability of the ski boot in the ski binding with easy entry and exit into and out of the binding. These and other objects are achieved on the basis of the characterizing features of patent claims 1 and 2. Numerous advantageous embodiments based on these features are the subject of the dependent patent claims.

To simplify the representations, the binding parts attached to the ski are mostly shown without hatching. The drawings show numerous basic embodiments of the invention and variants thereof, for example according to FIGS. 1 to 13, 14 to 22, 23 to 27, 28 to 38, 31, 32, 33 to 35, .36 to 38, Fig. 39 to 41, Fig. 42 to 44, Fig. 45 to 48, Fig. 49.50, Fig. 51 to 55, Fig. 56 to 58, Fig. 59 to 61, Fig. 62 to 67, Fig. 68 to 73, Fig. 74 to 77, Fig. 78 to 80, Fig. 81 to 85 and Fig. 86 to 89.

Many embodiments of the invention have in common the connection between the two binding units 1, 2 via two representable axes 3, 4, each of which is surrounded by an axis receptacle 5, 6 of the other binding unit to such an extent that the axis 3, 4 is still in the transverse direction of the axis 5, 6 can be detachably attached. In the illustrated exemplary embodiments, an axis 3 arranged closer to the shoe sole 7 serves to vertically fix the front area 8 of the ski boot 9, and an associated axle receptacle 5 has the shape of a slot, which is at least in the starting position of the ski binding or when the shoe is resting on the ski 9, runs parallel to the ski or its tread. Both axle mounts 5, 6 have a u-shaped cross section, which is thus directed parallel to the ski for the axle mount 5 of the axis 3. In contrast, for fixing both binding units 1, 2 in the longitudinal direction of the ski and for the lateral guide, the U-shaped cross section of the other axle holder 6 is directed perpendicular to the ski, from which in the Drawings only the surface 10 is indicated. Both axes 3, 4 have a circular cross section, so that they can be rotated in their associated axis receptacles like in a bearing shell. The slot-shaped design of the axle holder 5 enables a longitudinal displacement of the axle 3, which serves to compensate for the required distance between the axle holders 5, 6 when the other axle 4 moves on a circular path.

In the first basic embodiment according to FIGS. 1 to 13, one of the axis receptacles, i.e. the axle receptacle 5 for an axle 3 fastened to the binding unit 2 of the ski boot 9 closer to the sole of the shoe, rigidly molded onto the binding unit 1 permanently attached to the ski, and the second axle receptacle 6 is located either at the outer end of a resilient arm 12, i.e. if the second axis 4 is also attached to the binding unit 2 of the ski boot 9 or at a corresponding point on this binding unit 2, as the example of FIGS. 7 to 9 shows. In the latter case, an axis 4 'is provided on the resilient arm 12 instead of an axle receptacle 6.

In all embodiments of the invention, both the resilient arm or a corresponding spring element and the axes 3, 4, 4 'can consist of several parts arranged side by side in the transverse direction of the ski. For example, instead of an arm 12 in the form of a plate or spring tongue, several arm parts can run parallel to one another in the longitudinal direction of the ski at a distance. Instead of a continuous axis that is only held at its two ends, several axes can have the same geometric shape Axis pieces running transversely to the ski are present, whereby these can also be formed from one piece and are only partially enclosed by axle mounting parts. In such an embodiment, there is a hinge-like engagement between the axle pieces and the associated parts of an axle receptacle 5, 6.

A comparison between the four variants of the first basic embodiment with regard to the spring system, i.e. corresponding to Figures 1 to 6; 7 to 9; 10 and 11 and 12 and 13, shows that the resilient arm 12 can be made resilient in various ways, so that its free end, which carries the axle receptacle 6 or the axle 4 ', strives to be the counterpart of this axle connection 4, 6, 4 ', 6', ie to move the axis 4 on the ski boot or the binding unit 2 or the axle holder 6 'on the ski boot about the other axis 3 on a circular path. The spring force acting on the arm 12 consequently presses the ski boot 9 down onto the ski 10 about the axis 3, so that the ski boot 9 on the ski and side guide means attached to it, e.g. on a side guide rib 14 through a correspondingly shaped groove 15, it quickly finds its optimal side guidance and, moreover, in each pivoting position of the ski boot 9 relative to the ski 10 there is a secure and play-free connection between the two binding units 1, 2 that is under tension.

The variant according to FIGS. 1 to 6 has a binding unit 1 made in one piece from resilient plastic of high toughness, which in a side guide rib 14th bearing footplate 16 merges and is glued to the surface 10 of the ski. The modern adhesive technology enables a sufficiently strong bond to avoid additional screws. In addition, the binding unit 1 is also provided on the side facing away from the ski boot with a plate-shaped extension 18, so that a relatively large adhesive surface is available. The leaf spring-like binding arm 12 is integrally formed on the continuous binding or adhesive plate 20 via a base-shaped thickening 19 and extends in the longitudinal direction of the ski, so that a fork-shaped longitudinal cross section is present between the binding plate 20 and the binding arm 12. The opening width of this cross-section bifurcation enables a relatively large tilting movement of the ski boot 9, in that the upper axis 4 of the binding part 2 formed on the ski boot 9 can pivot downward correspondingly far about the lower axis 3. This tilting movement can be increased by a recess 22 provided at a suitable location in the binding plate 20, as illustrated in FIG. The variants according to FIGS. 5 and 6, 10 and 11 and 12 and 13 show how the mobility of the ski boot 9 can be increased by increasing the arrangement of the bearing receptacle on a bracket 23. 6 illustrates the resulting greater resilient bendability of the resilient binding arm 12.

In the variant according to FIGS. 7 to 9, a spring clip 25 is provided in the front binding unit 1, ie, permanently attached to the ski, one leg 26 of which is in the binding plate 20 'is positively inserted or cast in, while this fork-shaped other bracket leg 27 carries a housing plate 28 on which there is a recess 29 for the engagement of the tip of a ski pole to depress the axis 4' of the spring clip 25 to release the ski binding . Corresponding depressions 29 are also provided in the other embodiments of ski bindings according to the invention. The space between the binding plate 20 'and the housing plate 28 is filled, for example, by a rubber-like filler 30. The spring clip 25 consists, for example, of a closed, rectangular shape in the elongated form, the hairpin-shaped longitudinal legs of which are connected by the axis 4 'for the binding engagement and a transverse axis 31 as shown. The latter serves to anchor the spring clip 25 in the binding plate 20 '. The provided in the binding unit 2, ie on the ski boot 9 axle 6 'is formed in this embodiment in a correspondingly bent sheet metal part 32 which is fixed to the ski boot, for example by gluing, vulcanizing or otherwise.

The embodiment of Figures 10 and 11 shows that even with a ski binding according to the invention, the spring force can be generated by a rubber-elastic body 34 by this acting on the arm 12 ', at the free end of which the axle receptacle 6 is located.

The embodiment according to FIGS. 12 and 13 differs from that according to FIGS. 10 and 11 by the use of a compression spring 35 engaging the arm 12˝, the ends of which are held by bolts 36, 37 engaging in it.

The exemplary embodiments described below differ with the exception of the one according to FIGS. 33 to 35 from the previously described ones in that a part 3 .5 or 3 ', 5' of the rear axle connection in the longitudinal direction of the ski is provided on a binding part 39,39 ', 41,41', 42, 43,44,45,46 which can be moved upwards away from the ski against a spring force.

In the exemplary embodiments of FIGS. 14, 15 and 16 to 19 there is an axle receptacle 5 (FIG. 14, 15) or an axis 3 at the free end of a spring arm 39 or 39 ', which by its other end on Fastening base 47 of the binding plate 48 is rotatably attached. 14 and 15, the spring arm designed as a narrow plate extends between two outer and upper spring arms 40, which have the other axle receptacle 6 at the free end, so that it is bent upwards between them when the ski boot 9 according to FIG. 15 swings up when skiing. Both spring arms 39, 40 are formed from a piece of resilient plastic material on which there is a plate-shaped extension 49, via which the spring arms 39, 40 are firmly connected to the fastening base 47 by means of screws 50. According to Fig.16 to 19, the spring arms 39 ', 40' in one piece made of spring wire bow-shaped, so that the two cross pieces of the bracket form the axes 3 ', 4' of the binding unit 1. A mounting base 52, which encloses the connection areas 53 between the spring arms 39 ', 40' housing-like, holds them non-rotatably on the ski, so that the spring arm 39 'remains parallel to the ski surface 10 until the ski boot 9 is supported by its tip on the binding plate 54 55 pivots upwards. The connecting regions 53, which run in the shape of a circular arc, enclose on both sides inner pins 56, 57 which are formed on the fastening base and on which they have been placed against one another after being pressed transversely to the ski. The non-rotatable mounting of the connecting areas 53 is achieved, for example, by a bolt 59 which is guided transversely through the housing-like fastening base 52 including its side walls and thus the lower spring arm 39 '. The two upper, parallel to each other spring arms 40 'are interconnected by a short plastic plate 60 on which the recess 29 is for the engagement of the ski pole.

An upper and lower spring arm 40˝, 42 is also present in the exemplary embodiment according to FIGS. 20 to 22. The upper spring arm 40˝ is in one piece via a base part 62 the binding plate 63 is formed and is plate-shaped so that it can be bent out like a leaf spring. 21 shows it bent downwards by dashed lines, corresponding to a pivoting position of the ski boot 9, in which the lower spring arm 42, which is loaded by a compression spring 64, still rests on an elevation 65 of the binding plate 63 under the pressure of this spring 64. For example, there are two lower spring arms 42 running parallel to one another, which in the position according to FIG. 21 enclose the upper spring arm 40arm between them and are each loaded by a spring 64. The respective spring 64 is supported at a distance from the axle bearing 66 of the triangular spring arm 42 in side view and on the other hand on the base part 62.

The exemplary embodiments according to FIGS. 23 to 27 have a spring rocker 67, 67 ', which can be pivoted about an axis 71, 71' provided on the binding plate 69 or a base part 70, 70 'when the ski boot 9 is over the position shown in FIG. 24 or Fig. 26 pivot position further pivots upward. In the embodiment according to FIGS. 23 to 25, the spring rocker 67 is held in the position shown in FIGS. 23 and 24 by a tension spring 72 suspended in the base part 70, in which a rocker arm 41 with its axle receptacle 5 onto the binding plate 69 is depressed. In the embodiment according to Fig.26 and Fig.27 instead of above the axis 71 'on the spring rocker 67' engaging compression spring 73 is provided, which is on the other hand supports front elevation 74 of the binding plate 69. The other or upper rocker arm 75.75 'acts comparable to the upper spring arm 12.12', 12˝ of the embodiments of Figures 1 to 13 and is correspondingly resilient downward in the direction of the lower rocker arm 41.41 'to bend to counteract the upward pivoting movement of the ski boot 9 in the swivel range of the ski boot 9 between the positions of FIGS. 23 and 24. By arranging an extension 76, 76 'at the front outer end of the upper rocker arm 75.75', the pivoting range of the spring rocker 67.67 'can be limited to the front. The spring rocker 67.67 'with its rocker legs 41.75; 41', 75 'is formed, for example, from resilient plastic and has the width of the ski. The axes 3, 4 of the ski boot 9 are formed, for example, on both sides on a central web part 77, 77 'provided on the toe of the shoe, which engages in binding in a central slot running perpendicular to the binding plate 69 and in the longitudinal direction in the region of the axle receptacles 5, 6 .

According to the exemplary embodiment according to FIGS. 28 to 30, a rigid rocker 79 can be pivoted about an axis 81 provided on a base part 80 against the force of a compression spring 82, the two legs 43 and 83 of which have the axle receptacles 5, 6. The axis 81 is arranged only a short distance above the ski and when the ski boot is pivoted upward, the seesaw leg 83 dips into an elongated, in Ski countersunk arranged binding housing 84, in which the base part 80 is fastened and the compression spring 82 enclosing a guide shaft 85 is enclosed. If it is arranged in front of the base part 80, a tension spring can also be countersunk in the ski instead of the compression spring 82 in the ski. Above this housing 84, the known, for engagement with a groove of the shoe sole 7 certain side guide rib 14 'is formed. 30 shows the arrangement of two compression springs acting in parallel in the binding housing 84.

In the exemplary embodiment of FIGS. 31 and 32, axle receptacles 5, 6 are provided on two independently mounted and oppositely directed levers 44, 86, each of which is loaded by a spring 87, 88. The front lever 86 in the ski direction is mounted at the front end of a housing 89 recessed in the ski 10 about an axis 90 and is loaded upwards by a compression spring 87, so that the axle receptacle 6 strives to move the front axis 4 of the ski boot 9 upwards and thus Push shoe sole 9 down onto guide rail 91. The pivoting movement of the ski boot 9 that occurs during skiing presses the front lever 86 downward against the compression spring 87 and pulls the rear lever 44 upward against the force of the tension spring 88. The rear lever 44 pivots about an axis 92 provided at the front end of the guide rail 91 and at the same time pulls the displaceably guided guide rail 91 against the force of a second one Tension spring 93 to the front. Both tension springs 88, 93 act on the same extension 94 provided on the underside of the guide rail 91. For its slidable mounting on the ski, the guide rail 91 has, for example, a T-shaped cross section, the transverse web of which is guided in a channel.

In the embodiments of FIGS. 33 to 41, a more or less flatly extending bow made of spring steel is used, which has the shape of a rectangle oriented in the ski direction with two inner legs directed inwards, parallel to the longitudinal side bow legs, freely ending or angled at their ends 96, as shown in Figs. 35, 38 and 41. The inner legs 96 are each held flat in a central longitudinal channel 97 of the binding plate 98, 99, 100 to the ski surface 10, while the stirrup legs 101 form swivel arms which can be deflected in a spring-like manner. The bracket parts extending transversely between the bracket legs 101 and the inner legs 96 thus form torsion axes 102, and the bracket part connecting the bracket legs 101 forms an axis 3 ', 4' for engagement in an axle receptacle 5 ', 6' of the ski boot (Fig. 33- 35 and FIGS. 39-41) or for the mounting of an engagement body 106 connecting two such brackets 104, 105 according to FIGS. 36 to 38, on which the axle receptacles 5, 6 are located.

In the exemplary embodiment in FIGS. 33 to 35, there is only one rectangular bracket 107, which is held under the ski boot 9 by the binding plate 98. The axis 4 'forming bracket part is in engagement with the front axle receptacle 6' of the ski boot 9, which is formed in each case in two mutually parallel and perpendicular to the binding plate 98 web parts 109 which have between the bracket legs 101 and one having the axle receptacle 5 the binding plate 98 molded engagement bracket 110 engage, so that the axle receptacles 4 'include the axis 4' at points 111. The vertical to the ski fixed rear axle 5 is formed as a parallel to the ski surface slot, so that the extending between the two web parts 109 rear axle 5 in this axle 5 can perform a compensatory movement, which is necessary because the axis 4 'around the torsion axes 102 are moved on an arc when these are fixed in the ski direction between the channel 97 and stops 112 of the binding plate 98. As the exemplary embodiment in FIGS. 36 to 38 shows, instead of this the rectangular bracket 104 with its torsion axes 102 can also be displaceably guided in a longitudinal slot 113 of the channel 97. In order to be able to depress the axis 4 'for getting into the ski binding or for loosening, this is encompassed by a cross-section-shaped plate 114 shown by broken lines, on the leg 115 of which the recess 29 for the engagement of the ski pole is located. It reaches between the web parts 109 of the ski push 9. In order to be able to follow the pivoting movement of the ski boot 9, this plate 114, which also acts as a snow deflector, is held at its front end by integrally formed axle journals 116 in lateral slot bearings 117, in which it can also be displaced in the direction of the ski.

As in the embodiment according to FIGS. 36 to 38, two oppositely directed rectangular brackets 46, 118 are also present in the one according to FIGS. 39 to 41, the torsion axes 102 of which, however, are fixed in the ski direction. Since the bracket leg 101, or. the rectangular bracket 46,118, the axes 3 'and 4' change in distance from each other, has one of the axle mounts 5 'or 6' of the ski boot 9, in the example shown the rear, a slit-shaped cross-section, so that the associated axis 3 'in it a sliding movement can perform. This axle holder 6 'can advantageously be angled outwards, so that the axis 3' finds a stop when the ski boot swivels upwards. In the limit positions of the pivoting movement of the ski boot 9 shown in FIGS. 39 and 40, one of the axes 3 ', 4' of the rectangular bracket 46, 118 engages in a transverse groove 121 or 122 provided in an elevation 119 of the binding plate 120, so that this can support there under load from the ski boot 9. The elevation 119 also engages between the two, the axle receptacles 4 ', 5', parallel web parts 123, so that they for lateral guidance of the ski boot 9 contributes. For this side guide, the web parts 123 are also held between the stirrup legs 101. This embodiment of the invention, like those according to FIGS. 36 to 38, has a particularly flat construction, without binding parts being sunk in the ski.

The exemplary embodiment according to FIGS. 42 to 44 has, similar to that according to FIGS. 33 to 36, only one spring clip 125, which, however, is arranged in the opposite direction from the ski boot in the opposite direction to the front spring clip 118 of the exemplary embodiment according to FIGS. In contrast to the plate 114 serving as an entry aid, an opening in the form of an elongated hole 127 or a slot is provided as an entry aid in the engagement part 126 which projects forward in the shape of a nose and whose width is sufficient to accommodate the ski stick 128 in it. Bring engagement and the length of which is dimensioned for two engagement positions, which are indicated by FIGS. 42 and 43. The hole boundaries in the longitudinal direction are arranged relative to the front axis 4 'in the boarding position of the ski boot according to Fig. 42 and in its locking position according to Fig. 43 so that the tip of the stick or the ski pole 128 are supported on them laterally when pressure is applied to the axis 4' can and thus does not slide off the axis 4 '. If by entering the binding, the axis 4 'is already in the front part of the axle holder 5, a lever effect can be exercised with the ski pole in the space 129 between the axis 4' and the rear hole limitation 130, through which the ski boot with its axis 3 relative to the ski moves to the rear so that the axis 3 reaches the locking area of the axle receptacle 5 and the front axle 4 'engages in the front axle receptacle 6'. This means that there is no risk that the ski will slip when entering the ski binding. Even when getting out of the ski binding, the ski boot can be moved by lever action of the ski pole 128 in the corresponding front floor engagement space 131, ie forward, so that the axis 4 'moves out of the axle receptacle 6' again.

In a further development of the exemplary embodiment according to FIGS. 42 to 44, the exemplary embodiment according to FIGS. 45 to 48 allows the ski boot to be displaced relative to the ski by means of the ski pole into an additional latching position corresponding to the representation in FIG. 46, ie between three positions. For this purpose, in the protruding from the ski boot engaging part 126 'two longitudinally offset slots 132 and 133 are provided in the longitudinal direction of the ski, of which the front, shown in Fig. 45 in section, slot 133 by depressing the ski pole 128 in the indicated direction of the stick, the disengagement from the axle 6 'and subsequent moving by lever action of the ski pole in a second front axle 6˝ allowed. In this front running position of the ski boot there is a third axis 134 as a locking element in the locking position according to FIG. 46, in which it engages under a slot-like recess 135, which is designed similarly to one of the axle receptacles 5 described. This way the ski boot is full length attached to the ski, as is essential for the skating step. The skier can thus change the binding to a different type of use during a relatively short interruption of the journey without having to get out of the binding, depending on whether he wants to run with the usual cross-country skiing step or in the skating step. This binding is entered and released by stick-in-grip in the rear slot 132 in the same manner as previously described with reference to slot 127. It goes without saying that on the basis of this locking principle, a ski binding can also be implemented, by means of which locking is always carried out by means of a rear axle or an equivalent locking means, in which case the central axle 3 can then be dispensed with.

49 and 50 show an advantageous fastening system which can be used for numerous types of ski bindings. It is essential here to avoid fastening screws engaging directly in the ski. Instead, the binding continues downward in an elongated web 137 or 138, which is fastened in a correspondingly long groove 139 of the ski. The groove 139 can be formed by a U-profile 140 or 141 already embedded in the ski 10 during ski manufacture, the side walls of which are suitable for producing a firm connection to the web 137 or 138, either, for example, by a rough surface , for an adhesive connection according to Fig. 49 or for the intervention the spreading leg 142 of spreading parts 143 inserted in the web 138. For this purpose, the web 138 has a plurality of recesses 144 arranged one behind the other in the longitudinal direction of the ski, into each of which a spreading part 143 is inserted such that its transverse part 145 is in the recess 144 supported at the bottom. A threaded hole for an expanding screw 146 extends from above into the recesses and presses the inwardly angled expanding legs 142 outward so that they engage in the wall of the U-profile 141. In addition, the attachment of the binding to the ski can be reinforced by a plate 147 which is glued to the upper side of the ski and which adjoins the web 138 in one piece on the side. The web 137 or 138 inserted in the ski continues in the examples shown as a functional part of the binding upwards over the top of the ski, for example with the same width, and serves to guide the boot sideways by inserting it into a longitudinal groove 151 in the longitudinal groove 151 Shoe sole engages, as shown, for example, by the exemplary embodiments in FIGS. 42-44, 45-48 and 51 to 55. A web 137 or 138 can, however, be provided on each binding part to be fastened to the ski in order to enable a fast, accurate and firm binding assembly.

A cross-country ski binding is described in FIGS. 51 to 55, which differs from the previously described ones primarily in that the axle mount 156 preventing the transverse rotation of one of two axles 153, 154 is set back relative to the other axle mount 155, and because of this reversal According to the arrangement, the force of the right-hand spring on the axis 153, or the axle holder 156, acts downwards towards the ski in order to hold the boot down on the ski. A special mechanism is provided for locking the axle 153 in the axle receptacle 156, which is shown as an example in FIGS. 51-53. This mechanism has two locking slides 158 arranged in parallel, which are guided in sleeves 159 which are enclosed in the sole of the shoe. Both sliders 158 are connected to one another via a stiff wire bracket 159, and a part 160 projecting forward over the boot serves as an actuating part for the engagement of the ski pole 128 in order to counter the force 158 to a spring 161 in the release position according to FIG. 52 in each case move. To get into this ski binding, the locking slides 158 can also be pushed back by means of a bevel 162 provided on their underside when the shoe with the axle mount 156 is pressed onto the axle 153, which in turn is supported on the guide web 163 at the point 164. This web 163 has for engagement between the sleeves 159 at the front a narrower area 165 and there has an open towards the front, slit-shaped, parallel to the ski axle 155, the task of which corresponds to that of the axle mounts 5 and 5 'of the previously described embodiments , ie to transfer the vertical forces from the shoe to the ski without any spring travel. It goes without saying that the front axle connection 154/155 can be dispensed with if an occasional lifting of the boot from the ski accepts becomes. If lifted too far, however, the engagement between the web 163 and the groove 151 of the shoe would be lost.

In FIGS. 56, 57 and 58, two exemplary embodiments of entry aids are shown in addition to, for example, the exemplary embodiments in FIGS. 1 to 27, by means of which the pressing down of the spring arm 12 when entering and exiting is facilitated. In both cases, a depress lever 166.166 'is used. In the example according to FIGS. 56, 57, an actuating lever 167 is arranged opposite to the depressing lever 166 with respect to its pivot axis 168, so that the spring arm 12 is depressed by pivoting the actuating lever 167 upward. In this case, a lever movement of the ski stick 128 inserted into the opening 169 can advantageously be exercised. The equilateral with respect to the pivot axis 168 to the depress lever 166 'arranged operating lever 170 is depressed to depress the spring arm 12 at its end 171 by the tip of the ski pole.

59 to 61 show an embodiment of the invention corresponding to FIGS. 5 and 6, in which the spring arm 12 is divided into three mutually parallel spring legs 12a, 12b, 12c, of which the two outer ones are designed as working springs stronger than the middle one Spring leg 12c, which serves as a latching tongue when entering the ski binding. Its free end forms a half of the axle receptacle 6 through a fillet 173, the other half through the fillets 174 at the free end of the working springs 12a, 12b is formed. A bevel 175 on the latching tongue causes its deflection when the ski binding is entered, due to the pressure of the axle 4 until it engages in the axle receptacle 6. In this way, the working springs 12a, 12b only have to be depressed slightly when boarding, so that the desired spring preload is achieved. Getting into the ski binding requires a slight backward movement of the ski boot 9.

62 to 73 show two exemplary embodiments with a latching tongue 177, 178, which is arranged in an upward direction and has a bevel 179 controlling its deflection at its free end, so that the ski binding can be entered by putting the ski boot 9 on vertically. This results in a positive engagement between the two binding units 1, 2, which is locked by the latching tongue 177, 178. Both embodiments have an angular body 181, 182 which can be pivoted about an axis 180 fastened to the ski, the leg 183, 184 of which runs parallel to the ski has an axle receptacle 185, 186 for an axis 189 provided at the end of a spring clip 188, which presses it down onto the ski. Locking means and the latching tongue are located on the leg 190, 91 facing upwards.

In the exemplary embodiment according to FIGS. 62 to 67, on the leg 190 there are two axle receptacles 192, 193 arranged one above the other and open at the top, for axles 194, 195 or the same axis arranged on the ski boot 9 in a corresponding position Axle pieces provided. It goes without saying that the arrangement for a locking engagement can also be reversed, in that the locking element provided on the leg 190 or 191 is provided on the ski boot and that of the ski boot on the leg 190, 191. When entering the ski binding, the lower axis 194 of the ski shoe on the front of the leg 190 slides down into the axle receptacle 192, while the upward leg 190 is inserted between this axis 194 and the end face 196 of the ski shoe. The tip of the latching tongue 177 penetrates between the axes 194, 195 and is then deflected by its bevel 179 into contact with the upper axis 195 until its hook part 197 visibly engages over the upper axis 195. Fig. 66 shows the position of the latching tongue 177, which is formed in one piece with the angle body 181 made of plastic, with the greatest deflection. After complete locking, the end face 196 of the ski boot is supported on the back 198 of the leg 177. To open this ski binding, the tip of the ski pole 128 is inserted into a recess 197 at the tip of the latching tongue 177 directed obliquely upwards in order to resiliently bend it forward in the release position.

FIGS. 66 and 67 show a variant of the exemplary embodiment of FIGS. 62 to 65, in that the axis 189 of the spring clip 188 does not engage in an axle receptacle 185 which is elongate in cross section, but is encompassed on all sides by the axle receptacle 186. Instead, it is due to the swivel movement of the spring clip 188 required distance compensation achieved by the mounting of the spring clip 188 which is displaceable in a guide 199. However, a distance compensation is also possible by resilient deformation of the two legs of the spring clip 188, for which purpose these can be curved, as indicated by broken lines 200.

68 to 73, additional locking axes 194, 195 are dispensed with, so that only the axes 180 and 189 which are functional for the skiing movement are present. For the positive connection between the binding body 182 pivotable about the axis 180 and the ski boot 9, a receiving body 201 is provided on the tip of the shoe, which has a vertically directed receiving space 202 for the upward leg 191 of the pivoting binding body 182. This receiving body 201 is preferably made of a more rigid material than the body 203 forming the shoe sole, for example made of metal, and is firmly connected to it in a suitable manner, for example by gluing, vulcanizing or by means of non-illustrated, for example flexible extensions penetrating into the body. In order to facilitate a play-free placement of the receiving body over the divided leg 191, the leg 191 and correspondingly the receiving space 202 can be designed to taper slightly upwards. Between the two outer legs 191a and 191b, the latching tongue 178 is integrally formed on the resiliently pivotable binding body 182 as the leg 191c. When entering the receiving space 202, the Latching tongue 178, due to its upper bevel 179, returns to the position shown in FIG. 72 in order to then snap into the position shown in FIG. 73 above the upper edge 205 of the receiving body with its hook part 206. By engaging the recess 197 on the tip of the tongue or by hand, the latching tongue can be bent back into the release position. In order to ensure that ice that has not entered the receiving space 202, adjacent to the latching tongue, does not block the spring movement of the latching tongue 178, a cutout 208 is provided in the upper and middle region of the front boundary wall 207 of the receiving body 201.

In both of the above-described embodiments, the bearing block 210 for the fixed axis 180 is enclosed laterally from upwards in the outer legs 190a, 190b or 191a, 191b, parts 181a, 181b or 182a, 182b, and is in one piece with the elongated base plate 211 Ski binding formed, which is glued to the ski. Instead, however, a bearing block can also be provided on the edge of the ski in a manner not shown, between which the fixed axis 180 extends. These two pedestals for the lateral guidance of the ski boot can extend backwards in a rib-like manner on the ski edges.

In the exemplary embodiment of the invention according to FIGS. 74 to 76, the transverse stability of the ski boot and the resistance to its rotation about a vertical axis is complete a particularly large distance between the anchoring points in the longitudinal direction of the ski is further increased by the rear anchoring axis 212 engaging behind the axis 213 of the spring clip 214 on the binding unit 215 fastened to the ski. In this exemplary embodiment, too, there is a binding body 217 which can be pivoted resiliently about a fixedly mounted axis 216 and which has an angular longitudinal cross section. The leg of this binding body 217 which is directed upwards in the normal position according to FIG. 74 serves as an actuating lever 218 and has an engagement recess 219 in order to press it downward in order to get in or out into the position shown in FIG. When getting in, however, the binding body 217 can also be pivoted forward through the front anchoring axis 220 of the ski boot 9. In this position according to FIG. 75, the anchoring axes 212, 220 can easily be moved into their associated axis receptacles 221, 222. Due to the downward pressure on the axis 213 of the spring clip 214 engaging on the coupling arm 223, the binding body 217 and the coupling arm 223 move back into the position shown in FIG. 74, so that the anchoring axes 212, 220 are free of play from the axis receptacles with approximately 180 ° are enclosed. Since the axis 213 of the spring clip 214 continuously presses down between the anchoring axes 212, 220 in the axis receptacle 224, the parts which are coupled to one another in a scissor-like manner via the axis of rotation 225, ie the coupling arm 223 and the rear leg 226 of the pivotable binding body 217 into the Fig. 74 and 76 shown extended position spread like a toggle lever, so that the anchoring axles can be held in the axle receptacles 221 and 222 under prestress.

In this exemplary embodiment, the spring clip 214, which is formed from steel wire, but could also be molded from plastic, has three torsion axes 228, 228, 230 arranged one behind the other on both sides, by means of which the flexibility of the spring clip is increased. There are numerous options for the design of the spring clip, e.g. FIGS. 79 and 80 also show an embodiment of the invention that is comparable to that of FIGS. 42 to 44.

In this exemplary embodiment according to FIGS. 78 to 80, two axles 233, 234 and 235, 236 are formed by the spring clip 231, 232, the fixed axle 234 and 236 being held in a web 237, 238 fastened to the ski, which also supports the side of the ski boot 9 serves by engaging in a correspondingly shaped groove of the shoe sole. A housing 239, 239 'serves to support the front axle 240,240' and the lateral fixation of the spring clip 231,232 and thereby enables the pivoting movement of the spring arms 242 a, b and 243 a, b, which is guided in vertical grooves.

Fig. 81 to 85 show an embodiment of the invention, in which to achieve a very flat design of the binding unit attached to the ski when not in use, a manually operated locking lever 245 is provided is folded flat on the skin before getting into the ski binding or when transporting the skis, as indicated by the dashed lines in Fig. 81. When entering the ski binding, the locking axes 247, 248 arranged one behind the other reach under the ski boot 9 into the axle receptacles 249, 250, which are formed by receptacle recesses which are rectangular in cross section in the resiliently pivotable binding body 253. When the locking lever 245 is pivoted upward about its axis 254, which at the same time forms the pivot axis of the binding body 253, the rounded end 255 of the locking lever presses against the end face 256 of the ski boot and pushes it backwards, so that the locking axes 247, 248 in the U-shaped end region of the Axle supports 249, 250 are fixed vertically and horizontally to the rear. In the end position, the flat surface 257 bears on the flat end surface 256 of the ski boot 9, and, in this locking position, the locking lever 245 engages in the front axle receptacle 249. In addition, betrayal means, for example, can be provided between the locking lever 245 and the ski boot 9. As indicated by dashed lines at point 258, further locking points can be provided further back under the ski boot 9 in order to lock an engagement web 259 continuing from the binding body 253 to the rear with the ski boot 9. The mutual engagement at the locking points can also be achieved without an axis by means acting in an equivalent manner, such as, for example, helical teeth or mutual hooking and the like .. If the web 259 runs through to the rear of the ski boot to the rear, the locking between the locking axles 247, 248 and the axle receptacles 249, 250 can also take place on the heel of the shoe by means of this overlapping locking means, which can be caused by the ski pole or by Are unlockable by hand. For an engagement on the ski, a bottom web 261 with a triangular cross-section is formed on the base plate 260 and engages with a groove 262 of the web 259.

The exemplary embodiment according to FIGS. 81 to 85 further shows that, in contrast to those of FIGS. 62 to 73, the flat spring clip can also be arranged in front of the ski boot 9 instead of below it.

The exemplary embodiment according to FIGS. 86 to 89 has a functional similarity to that of FIGS. 62 to 73, with the essential difference that a separate, bow-shaped latching spring 265 is provided which, with an upward force on its latching axis 266, converts it into a downward direction brings open U-shaped recess 267 on the projecting part 268 of the toe snaps. There it can be actuated by the upwardly open recess 269 in the part 268 by means of the ski stick 128, similar to the exemplary embodiment according to FIGS. 42, 43. As shown in FIGS. 88 and 89, the latching axis 266 is held in two upwardly closed guides 270 by two side blocks 271, 272, between which the front part 268 of the ski boot 9 is guided.

The trestles 271, 272 also hold the toe on the binding body 274, which is resiliently pivotable about the axis 273, in the vertical direction, in that lateral webs 275 are inserted into horizontal slots 276 at the lower end of the guides 270, which at the same time serve to mount the bow-shaped latching spring 265. When pushing in, which can be carried out by the ski pole on the locking axis 266, a locking axis 277 provided under the ski boot 9 also enters an axially open rear axle receptacle 278 at the rear end of the binding body 274. The spring clip 279 forming the movement spring can also be used in this exemplary embodiment be attached to the base plate 280 of the ski binding in front of or behind the pivotable binding element 274, so that the binding element 247 is resiliently biased on the base plate 280 with its axis, ie the ski to hold down.

The above description shows that numerous embodiments are possible according to the basic principle of the invention, some of which have only been indicated schematically and cannot be complete. The use of a spring force directed at least approximately perpendicular to the ski or the ski boot, acting directly or via an intermediate body, on at least one axis securely held or guided in an axle mount, enabled a relatively large spring travel with a flat design and a freer design of the spring elements to achieve a more than the Optimal spring force distribution. The resilient axles or axle mounts enabled numerous advantageous embodiments for releasable engagement means in order to obtain an easy entry into and out of the binding. The predominantly shown application of spiral springs has proven to be particularly advantageous, the free end of which contains the axle or axle receptacle. The arrangement of the axes one behind the other in the longitudinal direction of the ski, combined with a spring force acting perpendicular to the ski, also gives the ski boot improved stability against rotation about a vertical axis. It goes without saying that the term axis is to be understood with regard to its axis effect around a geometrical axis oriented in the same direction, because a plurality of axis pieces provided at a distance from one another can effectively form an axis if they have the same axis.

In order to avoid having to provide an entire assortment of shoes for all foot sizes for different binding units 1 attached to the ski, in a further embodiment of the invention the second binding unit 2 'attached to the shoe is not, as usual, unsolvable, but as an adapter releasably attached to the shoe 9. This facilitates the variation between the numerous, previously described embodiments of a ski binding according to the invention. FIGS. 90 and 95 to 97 show examples of binding adapters which enable the use of different first binding units 1 in accordance with previously described exemplary embodiments with the same ski boot 9 'of known design.

The binding adapters 283 to 286 are form-fittingly adapted on the side facing the ski boot 9 Sk and also have a receiving slot 287 for the axle bracket 288, which is form-fittingly adapted to this, as also shown by the broken line in FIG. In the assembled state according to FIG. 94, two screw shafts 289, 290 engage behind the axle bracket 288 in its two angular regions with firm contact, which are screwed through threaded bores 291 that run transversely through the receiving slot 287.
