Description

SNOW SLIDER

The present invention relates to a snow glider with at least one device for fastening one of the shoes of the Schneeg Lei user to the green body of the snow glider.

Snow gliders of this type are already known. The bindings of these previously known snow gliders are firmly mounted on the glider body. When the snow glider is used, the driver's foot, which is supported on the base of the glider, assumes a position in which the longitudinal direction of the foot is almost perpendicular to the longitudinal direction of the snow glider. The longitudinal direction of the foot located on the front of the snow glider body, on the other hand, includes an acute angle with the longitudinal direction of the snow glider.

The size of these angles is individual. The permanently mounted bindings do not allow the individual differences in the angles mentioned to be taken into account.

The object of the present invention is to overcome the mentioned and still further disadvantages of the known snow gliders.

This object is achieved according to the invention in the snow glider of the type mentioned at the outset, as defined in the characterizing part of claim 1.

Exemplary embodiments of the present invention are explained in more detail below with reference to the accompanying drawings. It shows :

37 shows a front view and enlarges a section of the part of the snow glider shown in FIG. 36. The present snow glider has a base body 1, which is provided with at least one device 2 for fastening one of the shoes of the snow glider. The slider normally contains two such devices 2, which are arranged at a distance from one another. This distance is chosen so that the user of the snow glider does not find it annoying. However, since this distance also depends, among other things, on the physical proportions of the snow glider user, at least one of these devices 2 can be designed such that the distance between these devices 2 can be changed. For this purpose, it is sufficient if at least one of these two devices 2 is adjustably mounted on the base body 1. If the position of the two fastening devices 2 is adjustable, then another advantage is gained, namely that the position of the driver's center of gravity with respect to the longitudinal direction of the snow glider can be changed and optimally adjusted.

The fastening device 2 includes an anchoring plate 3, which in the example shown is incorporated in the base body 1 of the snow glider. This anchoring plate 3 can also be fastened to the surface of the base body 1 by means of suitable fastening means. The plate 1 embedded in the base body 1 according to FIGS. 1 and 2 is advantageously out of round so that it cannot rotate in the base body 1. The anchoring plate 3 has an approximately elliptical outer contour. In order to achieve an improved retention of the anchoring plate 3 in the base body 1, it has continuous openings 42 into which the material of the base body 1 can penetrate during the manufacture thereof. In order to keep the weight of the snow glider as small as possible, the anchoring plate 3 can have a variable thickness. In the middle, where a shaft 5 is connected, the thickness of the plate 3 is greatest and this thickness decreases in the direction of the plate edge. The fastening device 2 further comprises a base section 10 and an adjusting device 4, which is located between the base section 10 and the anchoring board 3. The adjusting device 4 includes the shaft 5, which is mounted approximately in the middle of the anchoring plate 3. The shaft 5 is surrounded by a through tube 6, which is firmly connected at one end to the anchoring plate 3. The outside of the jacket of this pipe section 6 is surrounded by the material of the base body 1, this material advantageously adhering to the pipe section 6. In the area of the upper side of the base body 1, a disk 7 is fastened to the raw pipe 6, the edge part of which is provided with a ring gear 8. This ring gear 8 is located on the top of the disc 7 and it has an internal toothing, so that this toothing is accessible from above and from the inside. The edge portion of the disk 7 also has radially extending and obliquely downward-extending tabs 9, which are incorporated in the material of the base body 1. These flaps 9 located far from the center of the disk 7 represent a means which is intended to prevent the disk 7 from rotating.

The fastening device 2 has the base part 10 already mentioned, on which one of the shoes 11 of the snow glider user can be located. Approximately in the middle of the underside of this base section 10, an essentially cup-shaped, low and hollow structure 12 is connected to the underside of the base section 10, which can also be referred to as a flat bell. The inner diameter of this bell 12 is selected so that the ring gear 8 just fits into this bell 12. The central region of the bell or pot 12 is provided with a round opening, the diameter of which is so large that the upper end part of the tube piece 6 fits into this opening. The bell 12, which is firmly connected to the base plate 10, is centered with respect to the ring gear 8 by means of this opening and the upper end part of the pipe section 6. In the area of the central opening in the bell 12 closes a cavity 13 in the base plate 10 to this opening, in which the upper end of the shaft 5 protruding from the slider base body 1 is located. The bottom of this cavity 13 is provided with a flat bearing sleeve 14, in which said shaft end is mounted.

The base section 10 is, as can be seen from FIGS. 1 and 3. Elongated, with a tapered area 15 in its center. The above-described mounting for the fastening device 2 is located in this central region 15. The wider end regions or end pieces 16 and 17 of the base part 10 are provided with means for holding the tip and the heel of the shoe 11. These funds are implemented as a security bond.

In the heel area 16 there is an automatic heel unit 18, the dimension of which in the longitudinal direction of the base plate 10 should be as small as possible. This is because the width of the base body 1 of a snow glider is comparable to the length of a shoe worn by an adult. Under certain circumstances, a long automatic heel unit 18 would protrude beyond the outline of the snow gliding body 1. Automatic heel devices 18 are already known which meet the above-mentioned requirement. These are those automatic heels which are mounted in the end area of the heel and which act on the heel section of the sole from above. Such an automatic heel unit is shown in FIG. 2. The yoke 19 of this machine 18 is pivotally mounted in the legs of an approximately U-shaped heel plate 20, the web connecting this leg 20 of this plate 20 being located under the heel in a recess 21 in the heel end piece 16. This depression 21 extends practically over the entire length of the heel area 16. In order to be able to adjust the automatic device 18, the slide plate 20 can be provided with laterally toothed strips, the corresponding paralaxed strips in the heel end piece 16 of the basic part ¬ comb 10. With the help of these toothed strips, the load ge of the heel plate 20 can be adjusted in the longitudinal direction of the base plate 10.

The underside of the base plate 10 at the end of the heel end piece 16 can be seen with a slide plate 22, which is made of a slidable material, e.g. is made of a plastic, and which should prevent damage to the surface of the base body 1 by the end edge of the base plate 10 when the fastening device 2 rotates about the center thereof.

The tip or toe end piece 17 of the base section 10, like the heel end piece 16, is designed with a recess 21 in which there are laterally toothed strips (not shown). In this recess 21, an automatically triggering hold-down device 24 for the sole of the ski boot 11 is mounted in a longitudinally displaceable and snap-in manner. This hold-down 24 acts on the sole in the area of the shoe tip or the shoe front part. The shoe front part automat - 24 uss should also be as short as possible for the reasons already explained. Since there were no such automatic security devices 24 on the market, it had to be designed for the present case.

The sole hold-down device 24 (FIG. 2 and enlarged in 18 and 19) has a sole plate 23 which is mounted in the recess 21 of the toe end piece 17 of the base part 10. The underside of this sole plate 23 is provided with toothed strips (not shown) which mesh with the toothed strips in the recess 21 of the toe end piece 17. With the help of these toothed strips, ^" the position of the sole hold-down can be

24 in the longitudinal direction of the base section 10. At the front end or edge of the sole plate 23 is a front plate

25 attached, which protrudes from the surface of the sole plate 23 and is advantageously perpendicular to this. The end of the front plate 25 remote from the sole plate 23 carries a 'housing 26 in which the mechanism of the trigger for the sole edge holder or jaw 27 of the sun holder 24 is accommodated. The housing 26 is designed such that it extends rearward from the front plate 25, so that it lies at least partially above the tip of the lap. The front plate 25 is advantageously made so long that the underside of the housing 26 does not touch the upper part of the front tip.

The sole sole edge holder 27 is essentially arcuate, one of the end parts of this holder 27 being fastened to a pivot shaft 43. The other part of this holder 27 is pivotable and can be brought into engagement with the sole 28 in the area of the toe. The cross section of at least the pivotable section of the holder 27 is practically L-shaped, although this profile is rotated by 180 degrees. This means that the horizontal bar of this profile is on top and comes to rest on the sole edge from above. That material section of the holder 27, which corresponds to the vertical bar, comes to rest on the side surface of the sole 28. The shoe sole 28 can be held between two such holders 27 not in the horizontal but also in the vertical direction. Of the jaws 27 mentioned, only the rear jaw is shown in FIGS. 2 and 18, since the cut passes through the front jaw 27.

The lower end of the pivot shaft 43 has a pin 44 which is mounted in the hollow plate 23. The upper end of the pivot shaft 43 is mounted in the housing 26. This upper end of the pivot shaft 43 is provided with means (not shown) which enable this shaft 43 to work together with the mechanism of the automatic security device. The mechanism of the automatic security device can be of a type known per se.

On the Söhlenplatte 23 is a sliding insert 29, which is a slight slip of the Schuh-Vordertei les from the front automatic safety device 24 enables if the situation requires this.

3 shows three of the possible positions of the fastening device with respect to the longitudinal direction of the slider base body 1. As can be seen, the binding 2 can even be adjusted so that the longitudinal axis thereof runs practically parallel to the longitudinal axis of the base body 1. This position of the binding 2 is indicated in Fig. 3 with a continuous line. The binding or fastening device 2 can be in this position when the user of the snow glider can be towed up a slope by a trolley. The oblique and dashed position of the binding 2 corresponds approximately to the position which the foot on the front of the snow glider normally has. The position of the binding 2, which is drawn practically perpendicular to the longitudinal direction of the base body 1, corresponds approximately to the position of the driver's foot located in the rear region of the base body 1.

So that the position of the fastening device 2 with respect to the base body 1 of the snow glider can be changed and then fixed, the adjusting device 4 also comprises a latching mechanism 30 (FIG. 4) which is normally in engagement with the ring gear 8 and for Adjustment of the position of the binding 2 is decoupled from the ring gear 8. This latching mechanism 30 is arranged in the narrow area 15 of the base section 10. In this area a housing 31 is formed, the purpose of which is to protect the intermeshing parts of this device from snow and dirt. The housing 31 has an outer wall 32 which extends approximately vertically and in this section represents the side wall of the base section 10. The housing 31 also has a top wall 33 which extends from the outer housing wall 32 into the interior of the bell 12, this top wall 33 being connected to the base plate 10 in a watertight manner. The mechanism is located under the top wall 33. In the upper region of the side wall 32 there is an opening through which an operating lever 35 of the latching mechanism 30 passes. The outer arm 36 of this lever 35 serves to actuate the latch mechanism 30, and it extends approximately perpendicular ^■ to the longitudinal direction of the base plate 10. In the aperture limiting walls is mounted an axis 37, which passes through the lever 35, so that the latter in the opening is pivotable around them. The other arm 38 of the lever 35 is located in the interior of the housing 31 and has a downwardly curved course. The lower end of this second arm 38 carries a toothed segment 39, the teeth of which are directed against the teeth of the ring 8 and can be in engagement therewith. With the help of a spring 40 pressing on the lower end of the inner arm 38 and having a flat cross section, the toothed segment 39 is held in engagement with the ring gear 8 when there is no action on the actuating arm 36. The spring 40 can be V-shaped, for example, one leg of such a spring 40 being supported on the end of the inner arm 38 and the other leg of the same being supported on the vertically extending portion of the top wall 33.

Fig. 5 shows schematically and in a-hori zonta len section a section of Fig. 4. In Fig. 5 you can see the outer arm 36 of the operating lever 35, which is approximately perpendicular to the longitudinal direction of the base section 10. The housing 31 can also be seen, in which the upper section thereof has been removed in order to gain an insight into the interior thereof. In this housing 31, a section from the ring gear 8 with inner teeth is shown. The toothed segment 39, which is carried by the inner arm 38 of the actuating lever 35, engages with the ring gear 8. Between this arm 38 and the inner wall of the housing 33 acts the V-shaped spring 40, which lies in a plane running parallel to the upper side of the slider base body 1. If the position of the fastening device 2 relative to the base body 1 of the snow glider is to be adjusted, then the operating arm 36 is pressed down, for example with the other foot. As a result, the toothed segment 39 attached to the end of the inner arm 38 is brought out of engagement with the toothed ring 8 fastened on the base body 1. The binding 2 is now free and can be pivoted around the shaft 5 as desired. After the desired position of the binding 2 has been reached, the operating arm 36 is released, the toothed segment 39 again engages with the ring gear 8 and the position of the binding 2 that has just been set is thereby fixed. It should be clear that in the present snow glider, the fastening devices 2 can even be adjusted to such an extent that the glider can be climbed once from the left and then after the devices 2 have been pivoted about 180 degrees from the right.

The present snow glider is equipped with a brake 50 (FIGS. 3 and 6), which takes effect automatically when the fastening device 2 is relieved. This can be the case, for example, if the driver falls after the safety bindings 18 and 24 are triggered. The brake 50 has an axis 51 which is rotatably mounted on the upper side of the slider base body 1 in bearing blocks 52 and 53 and which runs essentially at right angles to the longitudinal axis of the slider base body 1. The first bearing block 52 is fastened close to the upper lateral edge 54 of the base body 1. The end of the shaft 51 which extends further behind this bearing block 52 is bent approximately at a right angle and acts as the actual braking element 55. When braking, this braking element 55 is directed downwards, while in the unactuated state it is almost parallel to the surface of the base body 1. The second bearing block 53 is arranged close to the bell 12, which laterally protrudes the base section 10, as can best be seen from FIG. 3. This second bracket 53 is in the base plate 10 let in a little. A part 56 of the end part of the shaft 51 located in this area of the brake 50 is also bent at right angles and this part 56 forms a return lever of the brake 50. The return lever 56 and the braking element 55 lie practically in the same plane.

On the top of the base section 10, a plate 57 is pivotally mounted with the aid of a shaft 58. The shaft 58 is fastened in the upper side of the base section 10, this fastening point 58 being located in the front area 17 of the fastening device 2. The plate 57 has an elongated fastening section 59, to which a round plate section 60 adjoins. The diameter of this round plate section 60 is smaller than the diameter of the bell 12. Since the bell 12, which also protrudes laterally from the base plate 10, is very small, there is a cavity between the top of this bell 12 and the bottom of that of the Base plate 10 laterally protruding part of the round actuating plate 60 available. The return lever 56 is located in this cavity. In the second bearing block 53 there is a spring (not shown) which acts on the axis 51 in such a way that the brake element 55 is moved downward and the return lever 56 is moved upward when the actuating plate 57 is relieved. This relieved state of the actuating plate 57 and the return lever 56 is indicated in dashed lines in FIG. 6. The representation indicated by continuous lines, on the other hand, shows the plate 60 and the return lever 56 in the loaded state, that is to say: when the shoe 11 is in the binding 2. In this loaded state, the braking element 55 is also in a practically horizontal position.

As can be seen from FIG. 3, the top of the base body 1 is provided with two stops 62 and 63. The first stop 62 limits the swiveling movement of the front part 17 from the front to the rear in such a way that the binding 2 has a maximum position perpendicular to the longitudinal direction of the base body 1. lung can take. The second stop 63 limits the pivoting movement of the fastening device 2 in such a way that it can at most pass from its transverse position into its longitudinal position. If the device 2 moves within these limits, then the return lever 56 is constantly under the actuating plate 57. Consequently, the brake 50 can be actuated in any of the mentioned positions of the binding 2.

5, the ring gear has 8 teeth with inclined flanks. To achieve greater security when locking, the ring gear 8 can be designed as shown in Fig. 9. The teeth 81 of this ring gear 8 have flanks 82 and 83 which run practically parallel to one another. The segment 39 which engages with such a ring gear 8 has one or more teeth 84, the flanks of which likewise run practically parallel to one another. The distance between the flanks of the segment tooth 84 is smaller than the distance between the flanks 82 and 83 of the gaps which are present between the teeth 81 of the toothed crane 8. So that the segment tooth 84 can enter the respective gap between the ring gear teeth 81 more easily, the ring gear teeth 81 have chamfers 85. The segment tooth 84 can also be folded in this way. If the teeth 81 and 84 are designed in this way, then it is practically impossible to disengage them under the action of a lateral force.

While driving, the user of the snow glider is in the lateral grazing position. This position requires that the underside of the shoe sole 28 is at an angle to the surface of the base body 1. This can be achieved in the present glider (FIG. 10), for example, by arranging a wedge 41 between the base section 10 and the relevant part 18 or 24 of the binding. The inclination of the keel 41 extends perpendicular to the longitudinal direction of the base section 10. If necessary, such a wedge 41 can be exchangeably fastened in the binding.

During the journey, the user of the glider carries out movements which are necessary for controlling the glider. The wedges with a fixed inclination prevent the driver from freely executing these movements. In order to remedy this, the base section 10 is designed such that its end sections 16 and 17 can pivot relative to their central section 15.

In a first embodiment of the slider which solves this problem, the shaft 5 has a cylindrical section 71 (FIG. 7) which is rotatably mounted in the feed-through tube 6. This shaft section 71 is designed with a locking plate 72 which engages behind a circumferential shoulder 77. This shoulder 77 is formed on the inner wall of the feed-through tube 6 and it lies in a circumferential groove; which is executed in the outer wall of this shaft section 71. The bearing of the shaft 5 in the feed-through tube 6 can, however, also be carried out in another way. The end of the shaft 5 protruding from the feed-through tube 6 is provided with a horizontal crossbeam 73 which is connected approximately in the middle of its length to the cylindrical shaft section 71 and which extends practically perpendicularly to the latter. The cross section of this cross bar 73 is advantageously angular.

The elongated base section 10 is, for example, made of a castable mass which, in the hardened state, allows the central, narrow area 15 of the base section 10 to be twisted. If necessary, this mass can be reinforced with glass fibers, carbon fibers or the like. In this mass, the cross bar 73 and the section of the shaft 5 protruding from the bushing tube 6 above are cast in. As a result, the base section 10 is rotatably mounted on the base body 1, the central, narrow area 15 of this section 10 not having any movement. conditions around the longitudinal axis of this base section 10 can perform.

As has already been explained, wider end regions or end pieces 16 and 17 adjoin the central region 15 of the batch 10. The underside of these end pieces 16 and 17 has two walls 74 and 75 which are at an obtuse angle to one another (FIG. 8) and which are connected to one another at their lowest point by means of a practically round transition wall 76. This transition wall 76 rests on the top of the base body 1 and it can roll on this when the end pieces 18 and 24 are pivoted.

When the athlete executes swiveling movements falling in the direction of travel, the corresponding forces are transmitted via the machines 18 and 24 to the base section 10. Since this is twistable, the end pieces 16 and 17 can make the same torsion movements with respect to the middle section Execute 15 of this basic section 10. In order not to hinder the execution of these movements, the underside of the end pieces 16 and 17 is as shown. V-shaped. These end regions 16 and 17 can thus perform pivoting movements, the size of which is given by the angle between the walls 74 and 75. The rounded transition wall 76 rolls on the base body 1. So that the middle and immovable area 15 of the plate 10 cannot hinder the pivoting movements of the shoe 11, it is expedient to make the surface of this area 15 deeper than the surface of the end parts 16 and 17. The top of the central region 15 can, however, also be rounded for this purpose.

The base section 10 of the fastening device 2, which is shown in FIG. 11, functions similarly to the base section 10 shown in FIG. 7, because the end pieces 16 and 17 are also opposite the central area 15 in the base section 10 according to FIG. 11 the base section 10 rotatable. 11, the base section 10 contains torsion elements 88, with between one respective one of these torsion elements 88 extends from the respective end piece 16 or 24 and the central anchoring piece 5 of the base section 10 and connects these pieces of the base section 10 to one another. The torsion elements 88 have a hollow and essentially cylindrical body 89, the ends of which are closed by sleeves 90 and 91. The outer diameter of the sleeves 90 and 91 can be the same as the outer diameter of the fuselage 89. The sleeves 90 and 91 are provided with a continuous opening 92, the diameter of which is smaller than the inner diameter of the fuselage 89. The cross section of the opening 92 in the sleeves 90 and 91 is advantageously angular, in particular square. A vertical section through one of these sleeves 90 and 91 is shown in FIG. 14.

The anchoring piece 5 is practically T-shaped, the end of its vertical beam 71 being located in the base body 1 of the snow glider. Here the vertical bar 71 can either be rigidly attached or rotatably mounted. At least the end portions of the horizontal beam 73 on the anchoring piece 5 are also angular in cross section, so that one of the sleeves 91 of the torsion element 88 can be attached to them. Since the opening 92 in the sleeve 91 is also angular, the torsion element 88 sits non-rotatably on the anchoring piece 5.

One of the end pieces 16 and 17 is assigned to the end of the torsion element 88 remote from the anchoring piece 5. The respective end piece 16 or 17 has a base 95 on which one of the binding parts 18 or 24 is attached in the manner already described. Of one of the side walls of the base 95, a profile piece is from 94 whose external cross-section of the inner ^Q uerschnitt the opening 92 in the sleeve 90 corresponds. This profile piece 94 is inserted into the angular opening 92 of the sleeve 90 and fastened there in a known manner.

12 and 13 are two embodiments of the end pieces 16 and 17 shown in a rear view. The end piece with the base 95 according to FIG. 12 can be used with that fastening device 2 which is located on the front of the slider base body 1. The end piece with the base 95 according to FIG. 13 can represent one of the components of the rear fastening device 2. The bases 95 according to the two FIGS. 12 and 13 can be provided with one of the automats 18 and 24 as described above, as described above. At the bottom, the respective base 95 has the floor parts 74 and 75 which have also already been described and which are at an angle gamma which is different from 180 degrees to one another. The inclination of the bottom part of surfaces 74 and 75 runs perpendicular to the longitudinal direction of base part 10.

The first of the partial areas 74 mentioned lies on the side of the base 95 facing the front part of the slider base body 1. The second partial area 75 is on the side of the base 95 facing the rear part of the base body 1. The angle alpha between the first partial area 74 and the upper side of the base body 1 is relatively large and is between approximately 20 and 40 degrees. This is so that the forward movement of the driver can be carried out as freely as possible. The angle beta between the second partial surface 75 and the surface of the base body 1 is smaller and is between 5 and 25 degrees. This is because the driver's inclination to the rear is normally less great.

With the base 95 (FIG. 12) of the end pieces 16 and 17 for the front fastening device 2, the surface or the recess 21 in the end piece is practically parallel to the top of the base body 1. With the base 95 of the end pieces 16 and 17 for the rear fastening device 2, the surface of the base 95 is inclined with respect to the upper side of the base body 1. Here, the bottom of the recess 21 is inclined forward so that the driver's foot can assume the natural posture obliquely towards the front even in the rest position. This initial tendency The easiest way to reach the base 95 is that the profile piece 94 is attached to the base 95 in a rotated manner. With this base 95 for the rear fastening device 2, the partial surfaces 74 and 75 can be arranged asymmetrically with respect to the vertical central plane of the base 93. The angle between the second partial surface 75 and the side wall 96 of the base 94 can be the right, as shown in FIG. 13, so that the angle beta is smaller than the angle alpha.

If the ^Q uerbalken 73 of the anchoring piece 5 is to be rotatable, it can be placed on the center rail 71, it being possible for he may rely ab¬ on a shoulder 98 on the ittelbalken 71 (FIG. 11).

The torsion in the base section 10 can also be achieved in such a way that it has only a single torsion element 88 which extends between the end pieces 16 and 17. This embodiment is shown in FIGS. 15 to 17. In Fig. 15 only one half of such a base section 10 is shown because the other half of the same is of the same design. This base section 10 has a rigid shaft 100, the profile of which is angular, advantageously square, and the ends of which are fastened in bearing blocks 101. These bearing blocks 101 are fastened to the base body 1 with the aid of screws 102 (FIG. 16) and they are located in the region of the respective end piece 16 or 17. The torsion element 88 is tubular. Thereof in the central region, the cavity 92 in the element 88 over a certain distance 103 has a smaller diameter than usual, and during l resembles the shape of the cross section in this cavity 92 the ^Q uerschnitt the shaft 100. The diameter of the outside of this central portion 103 lying parts of the element 88 is larger than the diameter of the shaft 100, so that these parts of the element 88 can be rotated relative to the shaft 100. At these parts of the torsion element 88, the end pieces 16 and 17 are non-rotatably fastened. The rear section of the end pieces 16 and 17 has a Ni 104 in which the bearing block 101 is located, so that the fastening device 2 is as short as possible. The end pieces 16 and 17 can be of essentially the same design as shown in FIGS. 12 and 13. The only difference is that the end pieces of this embodiment do not have any profile pieces 94 at the base, but that they are joined through bores 105 are provided, through which the shaft 100 passes with play.

By means of the swivel mechanism described, the setting angle between the shoe and the slider base body can be changed quickly and as often and as often as desired. The snow slider body is not, as was previously the case, injured and weakened by drilling further holes for new adjustments of the binding. The binding can be adjusted according to the individual learning phases of the user as well as the respective snow and terrain conditions. On a drag lift, the front binding can easily be set parallel to the direction of travel, which enables convenient transportation using the drag lift. The distance of the bonds can be changed for different body sizes of the conductor users. Not only bindings can be used on the binding base plate which automatically trigger when overloaded, but also those which only use straps or the like.

The base section 10 can, as can be seen from FIG. 20, be designed as an elongated body with an essentially square cross section. Its central area 15 is connected to the actuating device 4. The end regions 16 and 17 of the base section 10 are provided with means 18 and 24 for holding the heel and the tip of a boot, advantageously an ordinary ski boot. The respective holding means 18 or 24 is attached to a sliding plate 20 or 23, which is displaceable along the base section 10. These sliding plates 20 and 23 are in the ^Q uerschnitt practically U-shaped. The legs 114 (FIG. 21 ^{) of} the respective slide plate 20 or 23 are relatively short. The length of the p-shaped web 115 connecting the legs 114 is somewhat larger than the width of the base section 10, so that the legs 114 of the sliding plate 20 or 23 can rest against the side surfaces of the base section 10. The free end portions 115 of the legs 114 are bent inwards and they engage behind the lateral edges of the base portion 10. This ensures that the sliding plates 20 and 23 are guided along the base portion 10.

So that the slide plates 20 and 23 can be moved easily and without play along the base section 10, there is a slide insert 29 between the top of the base section 10 and the web 115 of the slide plate 20 or 23 concerned. These slide inserts 29 are advantageously made of a plastic and the length of the latter is greater than the length of the web 115 in the longitudinal direction of the base section 10. Consequently, an extension of the inserts 29 extends towards the center 15 of the base section 10. The position of the sliding plates 20 and 23 along the base section 10 can be adjusted, for example, with the aid of spindles 117 (FIG. 21) known per se, which are mounted in the base section 10 and whose threaded parts are also fastened to the sliding plates 20 and 23 Nuts (not shown) are engaged.

In the heel area of the base section 10 there is a yoke or Strap 19, which can act on the heel section of the shoe sole from above. The yoke 19 is designed as a piece of rigid wire, vortei lhaft from spring steel, which is substantially U-shaped. The end portions 118 of the legs 111 and 112 of such a yoke 19 ... are bent inwards and they are pivotably mounted in the legs 114 of the heel sliding plate 20. The yoke 19 is angled approximately in the middle of the length of the limbs 111 and 112 transversely to the longitudinal direction of the latter, so that the respective bow limbs 111 and 112 send a first and adjoining the inwardly bent end parts 118 and extending obliquely upwards Section has when the bracket 19 rests on the top of the heel section of the shoe sole. This sloping section is then followed by a practically horizontal section of the leg 111 or 112 (not shown), these horizontal leg sections resting on the upper edge of the shoe sole. An arcuate web 113 extends between them and connects the ends of the legs 111 and 112 facing away from the heel plate 20.

The holding means 24 in the toe region have an essentially V-shaped bracket 120, the legs 121 and 12 of which likewise have end parts 118 which are bent inwards. These end portions 118 are pivotally mounted in the toe slide plate 23, this bearing being carried out practically the same as the bracket 19 of the heel Haltemi tel 18. The respective leg 121 or 122 of the bracket 120 has an outwardly curved course, so that the bracket 120 can be brought over the square sole in the toe area. The web 123, which the other ^'"s Endparti of the legs 121 and 122 connects, proceeds at this bracket 24, and a straight line on this web 123 is a ferrule 125 mounted pivotally tip portion of the sole in Schuh¬.

The clamp 125 has a substantially plate-shaped base body 126, in which a bore 127 with essentially lean smooth inner walls is executed. This bore 127 runs parallel to the larger surfaces of the base body 1 6 and the axis of this bore 127 is practically perpendicular to the narrower side surfaces 128 of the base body 126. The section 130 of the base body 126 located above this longitudinal bore 127 serves as an actuating lever for the Clamp 125 and it is provided with depressions or projections 131, which are intended to make it easier to grip this lever 130. The section 132 of the clamp 125 located below the longitudinal bore 127 serves as an active lever which acts on the upper side of that section of the shoe sole which is located in front of the shoe upper part in the area of the shoe seat. The base body 126 is widened in the region of the front edge 133 of the active lever 132 and the front edge 133 itself forms a concave arc. The front of the upper part in the area of the shoe tip is normally convex round and this round part comes to lie in the curved front edge 133 of the clamp 125 when this binding part 24 is closed. The front edge 133 shaped in this way prevents the tip of the shoe from shifting to the left and right during travel in the binding 24, which would impair the guidance of the glider.

A threaded bore is also made in the base body 126 of the clamp 125, in which a set screw 134 is screwed. The axis of this threaded bore extends almost perpendicular to the main surface of the ferrule 125. The screw 134 has the form of a grub screw, the _^ top of this set screw 124 tip against the heel section 18 of the binding and thus also against the Schuh¬ is directed towards. The tip of the set screw 134 can rest on the front of the shoe upper when the binding is closed. With the aid of the adjusting screw 134, it is possible to set the path which the clamp 125 can cover when the binding is closed.

Fastening device 2 (FIG. 20) includes an anchoring tion plate 3 (FIGS. 22 and 221), which in the example shown is attached to the top of the base body 1 of the snow glider. A rotor 135 (FIG. 23), which essentially has the shape of a flat ring, rests on this anchoring plate 3, the upper side of which, with the exception of its edge part, is essentially flat. On the rotor 135 is a plate-shaped intermediate disk 136 (FIGS. 26 and 27), the outer edge of which rests on the upper inner edge of the rotor 135 (FIG. 27) and which is advantageously made of a plastic. This washer 136 is covered with a retaining washer 137 (FIGS. 24 and 25), which is also made of a rigid material. Connecting means, for example rivets, are provided (not shown), the heads of which rest on the upper side of the holding disk 137, the bolts of which through openings in the holding disk 137 and in the intermediate disk 136, through the inner opening in the annular rotor 125 and through openings 142 pass through in the anchoring plate 3, the portions of the bolts projecting from the underside of the anchoring plate 3 being deformed into heads. The aforementioned constituents thus form a whole, which can be fastened to the slider base body 1 via the anchoring plate 3.

The anchor plate 3 is shown in FIGS. 22 and 221. In Fig. 22 this plate 3 is in plan view and in Fig. 221 it is shown in a vertical section II. It has a base body 140 which has the shape of an essentially flat ring. Foothills 143, 146, 148 and 149 adjoin the outer edge part of this ring 140. Bores 142 for the connecting means already mentioned are made in the vicinity of the central opening 141 in the ^" annular base body 140. The arrow L in FIG. 22 roughly shows the longitudinal direction of the slide body 1, this arrow pointing out - serdem also indicates the position of the tip of the slider body 1. The narrowest of all extensions 143 on the anchoring plate 3 is merely provided with an opening 144 through which one of the screws 145 (FIG. 20) passes, with the aid of which the anchoring plate 3 is fastened on the base body 1. This fastening screw .15 has a countersunk head and the fastening opening 144 is designed to receive such a countersunk screw 145 (FIG. 221).

A further extension 146 is located approximately diametrically to the narrowest extension 143 and is somewhat wider than the first extension 143 and also has a fastening opening 144. In addition to this fastening opening 144, however, a further opening 147 is made in this extension 146, which opening is intended for receiving a pin of the actuating device 4. The design of this adjusting device 4 will be described in more detail below. The position of the medium-wide extension 146 is selected with respect to the longitudinal direction L of the base body 1 such that the longitudinal axis of the base part 10, which is rotatably and snap-fitted on this anchoring plate 3 with respect to the base body 1, with the longitudinal axis of the slider - Basic body 1 collapses.

To the left and to the right of the middle-wide extension 146 there is a further, however, relatively wide extension 148 and 149. These extensions 148 and 149 are essentially of the same design. With regard to the position of these extensions 148 and 149, it can also be said that the respective wide extension 148 or 14 is located on the outer edge of the ring 140 between the narrowest extension 143 and the medium-wide extension 146.

Each of the broadest or widest runners 148 and 149 has one of the fastening openings 144 and next to it is also provided with a number of the latching openings 147 already mentioned. The latching openings 144 form a row at the respective extension 148 or 149, the course of which is curved. A such a row of latching openings 147 extends along a circular section. The center of this circular section coincides with the center of the central opening 141 in the anchoring plate 3. That portion of the respective broad extension 148 or 149, in which the latching openings 147 are made, faces the medium-wide extension 146, in which that latching opening 147 is made, which defines the longitudinal position of the base section 10. The fastening opening 144 in the respective broad extension 148 or 149 only follows this row of latching openings 147. This fastening opening 144 is thus made in that section of the wide extension 148 or 149 which faces the narrowest extension 143.

The base section 10 of the fastening device 2 can be pivoted out of its longitudinal position either to the left or to the right, so that it is at an angle to the longitudinal direction L of the slide base body 1. When swiveling to the right, the means 24 for holding the toe are located close to the right edge of the slider base body 1. When swiveling to the left, the toe is located close to the left glider edge. In this case, the already mentioned pin of the adjusting or latching device 4 can be brought into engagement with one of the latching openings 147 in the wide extension 148 or 149 concerned. As a result, the set position of the base section 10 is fixed until it is unlocked by a renewed actuation of the locking device 4 and is changed as desired. The wide runners 148 and 149 thus enable the base section 10 to be set obliquely with respect to the slider base body 1, in such a way that the slanted position of the base section 10 with respect to the base body 1 appears optimal to the user of the slider. The angular distance between the adjacent latching openings 147 of one of the rows of openings is advantageously 7 degrees, which should enable a sufficiently fine adjustment of the fastening device 2 relative to the slider base body 1. On the underside of the anchoring plate 3, material accumulations 150 (FIG. 221) are embodied which surround the lower openings of the openings 142, 144 and 147 and thereby extend them downwards. The opening mouths extended in this way are practically on the same level. The lower opening of the openings 142, through which the connecting means for the anchoring plate 3, the rotor 135, the intermediate disk 136 and the holding disk 137 pass, is provided with an extension 163 which is used to receive the end head of the connecting means, for example one Rivet, is determined. In the area of the upper mouth of the latching opening or latching openings 147, material accumulations 151 are implemented. One of these material accumulations 151 is also assigned to the latching opening 147 in the medium-wide extension 146. At the wide outlets 148 and 149, the upper material accumulations 151 assigned to the individual latching openings 147 form connected segments 152. One of these segments 152 is shown in a side view in FIG. 221 on the right.

The underside of the base body 140 is provided with flat recesses 153, from the bottom of which the lower material accumulations 150 and reinforcing ribs 154 rise (FIG. 221). The reinforcing ribs 154 also extend along the edge of the anchoring plate 3.

On the anchoring lath 3 is the rotor 135, which also has the shape of a flat ring and which is shown in Fig. 23 in a plan view. The ring 135 comprises two almost semi-ring-shaped segments 156 and 157, the end parts of which are connected to each other by means of a web 158. On the top of the end parts of the respective ring segment 156 and 157, a lower ring 155 is attached, which is intended to receive one of the ends of a spring to be described. Each web 158 has straight side edges which extend between the ends of the ring segments 156 and 157. Raised in the area of the respective web side edge a tab 159, which is practically perpendicular to the plane of the web 158. 231 shows that part of the rotor 135 which is located on the left in FIG. 23. Each web 158 thus has two lobes 159 projecting upwards. A continuous opening 160 is implemented in each tab 159, in such a way that the openings 160 in all four tabs 159 of the rotor 135 are aligned with one another.

The outer edge part of one of the ring segments 156 is provided with an extension 161 (FIGS. 23 and 231) which is designed to accommodate a locking mechanism 162 (FIG. 232). This locking mechanism 162 comprises the locking pin 164 already mentioned, which can be brought into engagement with one of the locking openings 147 in the anchoring plate 3. The extension 161 is designed as a material strip which is connected at one end to the ring segment 156 and which is bent such that it has an approximately U-shaped course. The U-shaped extension 161 lies on one of its legs 1 ^: 181, the free end of this leg 181 being connected to the ring segment 156. The other leg 182 of the U-shaped extension 161 also runs horizontally and is located at a distance from the first, lower leg 181. In the legs 181 and 182, openings 183 are made which are aligned with one another and through which the locking pin 164 passes .

The locking pin 164 has a lower part 184 and an upper part 185, the diameter of the upper pin part 185 being smaller than the diameter of the lower pin part 184. The diameter of the opening 183 in the lower leg 181 is accordingly larger than the diameter of the opening 183 im upper leg 182. The upper edge portion of the lower pin section 184 is located in that free space which is delimited at the top and bottom by the legs 181 and 182. That part of the thinner section 185 of the locking pin 164, which is located between the legs 181 and 182, is surrounded by a compression spring 186. The lower end of this coil spring 186 lies on the upper edge of the thicker section 184 of the pin 164. The upper end of the compression spring 186 lies on the underside of the upper leg 182. In the unactuated state, this spring 186 forces the locking pin 164 to remain in its lower position, which is shown in FIG.

The upper end of the locking pin 164 lies above the upper runner leg 182 and it is pivotably mounted in a lever 190 lying on the upper side of the upper runner leg 182. For this purpose, the lever 190 has a recess 191 which is located approximately in the middle thereof and which opens downwards. The upper end of the locking pin 164 lies in this recess 191 and a pin 192 passes through this pin end and through the wall sections of the lever recess 191 which laterally extend to this pin, by means of which the locking pin 164 is connected to the lever 190.

The lever 190 acts as a one-armed lever. The end part of the lifting ratchet 193 shown on the right is rounded and it lies on the upper runner leg 182. The section 194 of the lever 190 shown on the left is so long that its end portion protrudes laterally from the extension 161. If this lever section 194 is lifted by hand, the lower pin section 184 leaves the latching opening 147 in the anchoring plate 3 and the rotor 135 can be pivoted about its center.

The extension 161 for receiving the locking mechanism 162 is arranged on the circumference of the rotor 135 such that the longitudinal axis of the base section 10 runs parallel to the longitudinal axis of the slider base body 1 when the locking pin 164 in the locking opening 147 of the medium-wide extension 146 on the anchoring plate 3 is engaged.

The position of the rotor 135 on the anchoring plate 3 is not determined by the shape of the anchoring plate 3, because the loading Contact surfaces of these components 3 and 135 are essentially flat. The position and thus also the center of rotation of the rotor 135 relative to the anchoring plate 3 are determined with the aid of the holding plate 137 already mentioned (FIGS. 24 and 25). The base body 165 of the holding plate .137 is designed as a rigid disk, the edge part of which has a step-shaped circumferential shoulder 166. The offset edge portion 166 is higher than the remaining part 167 of the disc base body 165. The underside of the edge portion 166 thus has a circumferential and step-shaped free space in cross section, which is at the top through the underside 168 of the offset edge portion 166 and laterally through the inner Edge 169 of the paragraph is limited. The step 166 is designed such that the diameter of the inner flank 169 is somewhat smaller than the inner diameter of the annular rotor 135, so that the upper inner edge of the rotor 135 in the free space that is internally limited by the step 166 Can find space.

In the middle part 167 of the holding disc 137, four openings 142 for the passage of the connecting means already discussed are designed for this rotating mechanism. These openings 142 are arranged such that they can be aligned with the corresponding openings 142 in the anchoring plate 3 when the retaining washer 137 lies on the anchoring plate 3. In the underside of the holding disc 137 there are four approximately wart-shaped projections 170.

So that the friction between the retaining washer 137 and the anchoring plate 3 lying underneath is as small as possible, the intermediate washer 136 (FIGS. 26 and 27), which has also already been mentioned, is made between a suitable plastic. This intermediate disk 136 likewise has an elevated and step-shaped edge section 171 which lies between the upper inner edge of the rotor 135 and the offset edge section 166 of the holding disk 137. The rest, ie the inner part 172 of the intermediate disk 136 has openings 172, through which the connecting means can pass with play. In addition, the inner part 172 of the thin intermediate disk 136 has openings 173, the position of which corresponds to the position of the wart-shaped projections 170 on the holding disk 137. If the three parts 137, 136, 135 and 3 lie on one another, then the approximately semicircular wart-shaped projections 170 go through the smaller openings 173 in the intermediate plate 136 and lie on the top of the anchoring plate 3. These projections 170 prevent the intermediate disk 136, which is made of a soft material, from being crushed between the holding disk 137 and the rotor 135 when the connecting means are tightened.

As has already been said, the base section 10 of the fastening device 2 is essentially square in plan view (FIG. 28 ⁾ . It has a base plate 175 which is essentially square and elongated and whose cross section has the shape of a very wide open V. The cross section of this base plate 175 can be clearly seen, for example, from FIGS. 21 and 31. 29 and 30 show the base plate 175 in a side view, so that the longitudinal bend in the middle of the base plate 175 can also be seen from these figures. The kink line 166, which is located at the deepest point of the V-shaped cross section, runs in the longitudinal direction of the base plate 175 and is practically in the middle of the width of this plate 175. Bumps are in the base plate 175 177 pressed through, which serve as stiffening ribs of this plate 175.

Tabs 178 with openings 179 protrude from the underside of base plate 175 (FIGS. 28 and 29), which are practically identical to tabs 159 on rotor 135. In the assembled state, the tabs 178 on the base plate 175 are assigned to the tabs 159 on the rotor 135 such that the openings 160 and 179 are aligned with one another in these. A shaft 180 (FIGS. 21 and 231) passes through these openings 160 and 179 and with the help of this shaft 180, the base section 10 is connected to the rotor 135. The base section 10 can be pivoted about the axis of the shaft 180 relative to the rotor 135 within certain limits.

As can be seen above all from FIG. 28, the plate 175 of the base section 10 has several pairs of openings. The middle pair of openings 195 and 196 is designed to receive limiting screws 197 (FIG. 31). In the area of the respective opening 195 and 196, bushes 198 are inserted in the base plate 175, which have an internal thread. The limiting screws 197 are designed as grub screws which are screwed into the bushes 198. The upper end part of the grub screws 197 is provided with a slot for inserting a screwdriver so that it can be adjusted from above. The lower end faces of the screws 197 rest on a protruding and circumferential bead 199 which is carried out in the top of the holding plate 137. The more the Madensc rob 197 protrude from the base plate 175, the smaller the pivoting range of the base section 10 around the shaft 180. With the help of the screws 197, the pivoting range of the base section 10 can be adjusted.

If the grub screws 197 are not fully extended, the base plate 175 could be freely pivotable about the shaft 180 and could take any position relative to the slider base body 1. This would be especially when climbing the binding of Nachtei l. In order to give the base section 10 a defined starting position, zero position dampers 200 (FIGS. 28 and 32) are provided. The j ewei li ge ^"damper 200 is designed as a strip made of a flexible plastic, has which a et¬ wa quadrangular cross-section. The strip 201 is bent in the middle of its length, so it that also has the shape of a wide-open V. In its central area, the underside 202 of the strip 201 is flattened, so that here a flat and practically horizontal support surface 203 is present. A bush 205 with an internal thread is embedded in the respective arm of the V-shaped damper 200 from the top 204.

To the left and right of the middle pair of openings 195 and 196 in the base plate 175 there are further pairs of openings 206 and 207. The distance between the bushes 205 on the damper 200 is equal to the distance between the openings 206 and 207 of these further pairs. Screws (not shown) are passed through the openings 206 and 207 and screwed into the bushes 205. In this way, two dampers 200 are attached to the underside of the base plate 175. The height of the damper strips 201 is selected such that the mounted damper 200 rests with its base surface 203 on the upper side of the holding disc 137. Since the support surface 203 runs horizontally, the zero position of the base section 10 is practically in a horizontal plane.

The material of the dampers 200 is flexible and this could not hold the base section 10 in the desired position of the latter during the journey. For this purpose, springs 210, in particular helical springs, are provided, which are attached to the underside of the base plate 175 (FIGS. 21 and 28). For fixing the springs 210, opening pairs 211 and 212 are implemented in the base plate 175, the underside of which is reinforced with a material accumulation 213. At this material accumulation 213, one end of the respective spring 210 is attached, for example with the aid of a screw. The other end of spring 210 rests inside ring 155, which is attached to the top of rotor 135.

30 shows the base plate 175 in a side view, the front section of the base plate being removed in the central region thereof in order to be able to use the holding and guiding means for the spindle 117. The spindle 117 is indicated in FIG. 30 with a dash-dotted line. For guiding and holding the spindle 117 in the central region 15 of the Base plate 175 is provided with tabs 214 protruding from the base 176 of base plate 175, which are designed with incisions, openings or the like, in which the correspondingly grooved parts of spindle 21 are mounted. The ends of the spindle 117 which lie in the end region 16 or 17 of the base part 10 are in engagement with the binding parts 18 and 24 and as a result they are guided in these regions 16 and 17 of the base part 10.

On the elongated base body 10 there is a first pair of springs 210 in the area of the shoe tip and another pair in the area of the shoe heel (FIG. 33). There may be a desire that the base plate 10 not only be tiltable about the shaft 180 but also in a further direction which is perpendicular to the axis of the shaft 180. This wish can be accommodated in that the opening .160 in the rotor lobes 159 or / and the opening 179 in the round plates lapping 170 are not designed as round holes, but as elongated holes. In the example shown in FIG. 33, the opening 160 in the rotor lobe 159 is designed as an elongated hole. If the pressure on the base plate 10 is greater, for example, in the area of the shoe tip than in the area of the heel, then the spring 210 in the area of the shoe tip is compressed more than the rear pair of springs 210 and the shaft 180 moves accordingly in the slot 160 of the front rotor lobe 159 down.

In addition, the elongated holes 160 and 179 in the tabs 15 and 178 provide a kind of cushioning of the shoe bindings with respect to the base body of the snow glider, which makes the use of the snow glider more pleasant if, for example, jumps are made with the snow glider.

So that the base plate 10 can also be lowered unhindered in each of its inclined positions, the tabs 159 and 178 are designed such that the free edge parts 215 and 216 thereof are rounded. In addition, the respective edge 215 or 216 facing end of the elongated hole 160 or 179 are possible close to this edge.

Instead of the tabs 159, 178 and the shaft 180 described above, blocks 220 made of tough but resilient material are used for the connection of the base plate 10 to the base body 1 of the snow glider (FIGS. 34 and 35). These blocks 220 can be made of a suitable plastic, for example. A block 220 is expediently arranged in the region of the shoe tip and a further block 220 in the region of the shoe heel, so that the central region of the elongated base plate 10 remains free and can be used for further purposes.

The respective block 220 can be made of an elastomer and can advantageously have a round cross section (FIG. 34). Such a block 220 is arranged such that its outer surfaces 221 and 222 are assigned to the parts 10 and 135 to be connected to one another. In the present example, the lower base area 221 of the block 220 is assigned to the rotor 135. Since the top of the rotor 135 is substantially flat, the lower base 221 of the block 220 can also be flat. A threaded bushing 223 is embedded in the lower base surface 221 of the block 220. If the block 220 has a round cross section, then the threaded bushing 223 can be located in the middle of the base area 221. However, the block 220 can also be made elongated. In this case, the longitudinal direction of this will expediently coincide with the longitudinal direction of the base plate 10. So that the connection between the base plate 10 and the base body 1 of the snow glider is more secure, a plurality of threaded bushings 223 can be embedded in the block 220 in one or more rows. It goes without saying that the elongated block 220 can also be arranged practically perpendicular to the longitudinal direction of the base plate 10 (not shown). A fastening screw 225 is provided, the bolt of which

226 can be screwed into the threaded bush 223. The head

227 of this screw 225 should have the largest possible area. In the rotor 135 or in another, on the base body 1 of the snow glider not even ^: pivotally fastened plate 135 is a continuous opening through which the bolt 226 of the screw 225 is inserted when it is to be screwed into the threaded bush 223. The plate 135 is clamped and held between the head 227 of the screw 225 and the base 221 of the block 220. Such plates 135 are also made of sheet metal and so that these are not deformed in the area of the bolt opening, the screw head 227 should have a large area.

Since the base plate 10 has a V-shaped cross section, the upper base surface 222 of the block 220 has a correspondingly shaped depression. It goes without saying that the shape of the contact surfaces on the block 220 can be designed in accordance with the shape of the object to be connected to this block 220. In the deepest area of the upper base

222 of the block 220 is also at least one threaded bushing

223 let in. In Fig. -34 only a further screw 228 is indicated schematically, with the help of which the base plate 10 is connected to the upper base surface 222 of the block 220. It goes without saying that in the case of non-planar surfaces it is possible to use any of the known connection means which can be used in the given case.

The brake 50 shown in FIGS. 36 and 37 has a depressible threshold 230, which is located in the central region 15 of the base section 10 of the fastening device 2. A bolt 231 protrudes from the underside of this threshold 230 and is directed downward. This bolt 21 passes through the anchoring plate 3 and it is coupled to one of the end parts 245 of a connecting rod 232. The other end of Ve ^{'rbindungsstange} 232 is provided with a mecha- nism 250 coupled, which is designed to carry out the braking operation Idet.

The floor plan of the threshold 230 can advantageously be circular or square (FIG. 36). The longitudinal axis of the bolt 231 which adjoins the underside of the threshold 230 coincides with the axis of rotation of the fastening device 2 for one of the athlete's shoes, so that the actuation of the brake 50 is independent of the angular position of the base part 10 of this device 2 is possible.

A housing 233 in the central region 15 of the base section 10 is designed to accommodate the threshold 230. This housing 233 is embedded in the central section 15, so that the bottom 234 of the housing 233 lies below the surface 238 of the middle section 15. The threshold 230 itself has a base plate 235, which is made of sheet metal, for example, and which lies in the housing 233, specifically above the base 234 thereof. A block 236 made of a resilient material is located on the base plate 235, for example from a suitable plastic, such as made of an elastomer, which is connected to the top of the base plate 235. The upper side 237 of the block 236 lies above the upper side 238 of the middle half 15.

A tube piece 238 is connected to the underside of the housing base 234, the longitudinal axis of which is approximately perpendicular to the housing base 234 and in which the bolt 231 is mounted so as to be longitudinally displaceable. That section of the bolt 231, which is located between the housing base 234 and the base 239 of the base section 10, is surrounded by a spring 240, for example a helical spring. This spring 240 presses on the underside of the base plate 235 and thereby keeps the threshold 239 in its upper position when no weight acts on the threshold 230 from above. In order to limit the path of the threshold 230 caused by this spring 240, the section of the bolt 231 protruding from the tube piece 238 is provided with stop means 241 Mistake. In the example shown, a pin 242 serves as such a stop means, which passes through the bolt 231 and whose end parts protruding from the bolt 231 strike the lower edge of the tube piece 238. However, the stop means 242 can also be used, which is attached to the outside of the bolt 231 or the like.

The longitudinally displaceable connecting rod 232 lies (FIG. 37) on the upper side of the base body 1 of the snow glider and it passes in the area of the anchoring plate 3 through an elongated recess 244 in the anchoring plate 3. The cross section of this recess 244 corresponds to the cross section of the connecting rod 232, so that it is guided in the recess 244 as freely as possible, but with as little play as possible. The connecting rod 232 can, for example, have a square cross section, the longer side of this profile lying on the base body 1. In the area of the bolt 231, the connecting rod 232 has a widened end part 245, in which a continuous opening 246 is made. This opening 246 is designed in such a way that the lower end part 247 of the bolt 232 can find space in this opening 246. The side walls of the opening 246 are practically perpendicular to the surface of the connecting rod 232. In the region of the end edge of this end part 245 of the connecting rod 232, an inclined surface 248 is made. This inclined surface 248 begins at the underside of the rod end parts 245 and rises in the direction towards the opening 246. The end of this inclined surface 248 is at a distance from the hand of the opening 246, so that this part of the rod end 245 represents a "ramp" for the lower end 247 of the bolt 232. The cutting edge or the beginning 249 of the ramp is therefore below, i.e. practically on the base body 1.

37 shows the threshold 230 in its lower, ie actuated position, as if a shoe were in the fastening device 2. Hence the lower end portion 247 of the bolt 232 in the aforementioned opening 246. As soon as the weld 230 is relieved, the spring 240 presses the base plate 235 upward and the lower end 247 of the bolt is pulled out of the opening 246 in the connecting rod 232. This releases the rod 232 and moves it to the right under the action of the mechanism 250, so that the opening 246 no longer lies under the bolt 231. The path by which the rod 232 shifts to the right is so long that the cutting edge 249 at the rod end 245 lies under the bolt 231 or even a little to the right of it. When the braking element 55 is brought into its horizontal, ie ineffective position, the rod 232 simultaneously moves to the left again. The edge 249 of the ramp 248 is pushed under the lower bolt end 247 and then moves further into the position shown in FIG. 37. The athlete will now insert his shoe into the fastening device 2, whereby the threshold 230 is pressed down and the lower end 247 of the bolt 231 reaches the rod opening .246. As a result, the rod 232 and thus also the brake element 55 coupled to it are held in their stated position.

The mechanism 250 (FIG. 36) comprises a holding plate 251 which is fastened on the base body 1 with the aid of screws 145. One of the edges of the holding plate 251 is flush with one of the side edges 54 of the base body 1. The braking element 55 has an approximately S-shaped body 252, the middle part of which is pivotally mounted in an eye 52 on the holding plate 251. The inner leg of the brake body 252, which is located in the area of the holding plate 251, engages with a drive spring 253, which can bring the brake element 55 into its operative position when the brake is actuated. The other leg of the brake body 252 lies next to the side edge 54 of the base body 1 and it is designed and designed to penetrate the snow, if necessary, in order to brake the snow glider and thereby to prevent that this glides down the slope in an uncontrolled manner.

A locking pin 254 engages with the brake body 252, which is under the action of a spring 255 and which is also coupled to the outer end of the connecting rod 232. When the connecting rod 232 becomes free, this relieves the locking pin 254 and this pulls back under the action of the spring 255. The brake element 55 is thereby released for braking.
