Abstract

The binding for a winter sports device consists of a plate (32) which is attached to the shoe of the person performing the winter sports, and of locking elements (40) which engage in recesses (34) in the plate (32). The locking elements (40) are, for example, fixed to the top of a ski or to the base plate of a winter sports device, on which skids are arranged via a pivoting mechanism. The locking elements have preferably reinforced heads under which engage the heads of pins (54) spring-loaded (58) against the locking elements (40). When a triggering force occurs, the pins are pushed back and thereby free the locking elements, so that the plate can be released from the winter sports device. The spring force of the pins (54) can be adjusted.

Description

The invention relates to a binding for a winter sports device, such as skis or a device with a base plate which is attached to skids via a pivoting mechanism, the device being attached to the shoes of a sportsperson.

A large number of bindings and in particular self-triggering safety bindings for skis for alpine skiing are known. As a rule, the athlete's shoe is clamped onto the sole and heel piece. The release of the bond, i.e. the force at which the winter sports device is released from the shoe of the sports driver is adjustable via springs. False tripping can include due to snow or ice adhering to the binding.

In winter sports equipment with a base plate and runners which can be pivoted parallel to this base plate, as is known from DE-PS 27 07 364, no practically applicable safety binding is known. Normally, only holding straps are arranged on the stand board, through which the front end of the shoes is inserted, the user standing approximately transversely to the longitudinal axis of the winter sports device. A winter sports device equipped in this way is not permitted for drag lifts.

With single-skid gliders, it is known to attach relatively large-format shoes firmly to the top, and the user of the winter sports device climbs into these fastened shoes with other shoes. On the one hand, it is difficult to find a firm hold in these shoes and, on the other hand, such a device is not self-releasing, so that the device is not released from the feet when the winter sports enthusiast falls.

The invention has for its object to provide a universally applicable binding for winter sports equipment.

According to the invention, this object is achieved by at the top Side of the winter sports device lockable locking element by a plate attachable to the shoe with recesses for receiving the locking elements, and by at least one guided in the plate bolt, the head of which can be fixed to a locking element.

In the present invention bonding of a base plate provided with a two parallel runners comparable pivotable slider _/ only the Ver¬ are at the Wintersport¬ device, such as on the top side of a ski or on the top of lock-out elements without any moving parts other fixed. The plate is arranged on the underside of a shoe or integrated in the sole of a shoe. The sportsperson climbs onto the winter sports device, the locking elements being accommodated in the cutouts in the plate. The bolt or bolts which protrude into the recesses with their heads are pushed back, and after the locking elements have been completely received in the recesses in the plate, the bolt heads are pushed back into the recesses and thus in the direction of the locking elements. They then stand against the locking elements and prevent the plate from being removed under normal conditions.

According to a preferred embodiment, the plate is formed from both narrow sides with elongated recesses or recesses, the bolts are spring-loaded and their heads protrude opposite each other, and the locking elements are approximately keyhole-shaped with fastening edges in cross section.

The recesses or recesses are formed in the form of incisions in the entire plate thickness. This prevents snow or ice from getting stuck in it. The locking elements are spaced apart from one another, so that when the plate is placed on it, it cannot move in the direction of the locking elements. The locking elements thus serve to determine the Plate in all directions. This embodiment of the

Binding is self-releasing since the plate can be pulled off the locking devices when a sufficiently large force is applied, the spring-loaded bolts being pressed against the spring force. The release force can be adjusted depending on the size of the spring force.

According to a further embodiment of a transverse pin at one end of the plate arranged reasonable through the recess, which cooperates with the pin lock is ^¬ element a block, the recess in the longitudinal direction with a Aus¬ is formed, and in the other recess for engagement the plate has a block formed with a bore in which the head of a bolt guided in the plate engages.

This embodiment represents a very simple binding, but it is not self-triggering. For example, in the front area, the plate is held over the transversely directed pin which engages in the longitudinal direction, while the rear area of the plate is anchored via the bolt engaging in the bore of the locking block.

According to a further preferred embodiment, a recess for receiving a locking element is formed in the plate from a narrow side and an elongated hole is formed in the area of the other narrow side, which is longer than the locking element to be received, and in the plate there is a bolt or an axis through the elongated hole to rest on one end of the locking element or on a stop on the winter sports equipment in the locking position.

In this embodiment, the plate can be pushed in the longitudinal direction onto the locking elements, which requires less force than if the locking bolts are pushed against the spring force by pressing so that they can assume their locking position on the locking elements. The bolt or the axis guided in the plate through the elongated hole prevents after the arrangement a displacement of the plate in the longitudinal direction. The bolt or the axis of this embodiment is preferably provided with a handle which can be fixed in the locking position on the plate.

In a further development of the invention, in the area of a locking element, a pivotable trigger arm, which is formed with lugs and can be actuated by means of a handle lever, is arranged in the plate. With this trigger arm, the plate can be raised relative to the ski or the base plate, with the spring-loaded bolts opposing it _r be pushed back zu¬ the force of the spring to the locking elements freizugebe This allows an activation of the binding.

According to a further preferred embodiment, transversely arranged elongated holes for receiving locking elements and longitudinally arranged bolts for fixing to the locking elements are provided in the plate.

The spring-loaded bolts are preferably provided with unlocking levers which, in the form of an eccentric, enable the bolts to be withdrawn from the unlocking position.

The strength of the springs on the bolts is preferably adjustable so that the release force of the binding can be individually adjusted.

The locking elements are preferably made of bent sheets, so that their production is possible at low cost.

The springs are preferably arranged coaxially with the bolts

According to a further embodiment, the springs are arranged at an angle to the bolts and the spring force is transmitted via a wedge engaging on the bolts. The springs are in particular arranged perpendicular to the bolts. This embodiment enables, for example, the arrangement of relatively long springs in the longitudinal direction of the Plate so that a large spring force can be exerted on the bolts.

Rubber pads and / or spacers are preferably arranged on the top of the plate and / or on the underside of the plate. The spacers provide a relatively small contact area between the winter sports equipment and the plate, so that freezing of the plate is prevented.

The plate is preferably or the like via straps. on one

Attachable shoe. But it is also possible to integrate the plate in the sole of a shoe.

The locking elements are preferably attached to the base plate of a winter sports device, which is also known as a snow surfer. In this case, the base plate with the swivel mechanism can be removed from the runners, locking elements then being attached to the runners, so that both the device as a whole and the removed runners can be driven with the same binding. If the runners are attached separately to the winter sports wearer's shoes, they can use existing drag lifts that are not approved for all winter sports equipment.

According to a further preferred embodiment, there is a disk that can be attached to the top of the device with an undercut arranged at least in a region of the peripheral surface, a plate that can be attached to the shoe with a recess for receiving the disk, and at least one that is guided on the plate spring-loaded pin is provided, the head of which protrudes into the recess for abutment in the undercut of the disk. In this embodiment of a safety binding, only 5 the pane is fastened to the winter sports device, for example on the top of a ski or on the top of the base plate of a glider provided with two parallel pivotable runners, without any other movable parts. The plate is arranged on the underside of the shoe or integrated on the shoe. The sportsperson climbs onto the winter sports equipment, with the disc being received in the recess in the blade. The or the will

_10th spring-loaded bolts which protrude into the recess with the head pressed back and after the washer has been completely received in the recess in the plate, the bolt heads are pushed again in the direction of the recess and thus in the direction of the washer. They are in contact with the circumferential surface of the disk and, depending on the design of the undercut, the shape of the bolt head and the spring force exerted on the bolt, the desired release force can be set.

According to preferred embodiments, the undercut is designed as a groove or as an inclined surface. The disk is preferably circular, and the groove, which is in particular V-shaped with a shorter lower and a longer upper leg, is circumferentially provided on the circumferential surface of the disk.

25: see.

In order to facilitate the reception of the disc in the recess of the plate, the disc can preferably have at least one cut-off area which is arranged transversely to the main fixing direction of the plate on the winter sports device 30. After arranging the plate around the

Disc is rotated, the plate together with the foot, so that the heads of the bolts are arranged in the area of the undercut.

35 In order to be able to safely assume the correct position of the plate on the disc, detent seats for the bolt or bolts are preferably provided in the groove. According to a preferred embodiment, the plate is an elongated rectangle, the recess for the disc is arranged approximately in the middle and from each narrow end of the plate at least one bolt is directed towards the recess. The bolts are preloaded via a helical spring and an adjusting screw. The adjusting screw is preferably provided with a set value scale in order to be able to set the triggering force dependent on the user quickly and reliably.

10

Channels for the bolts, springs and adjusting screws are preferably formed in the plate. The bolts have a collar at their rear end, with which they abut against a stop surface in the plate, so that they cannot be pushed completely out of the plate. The bolts can be circular in cross section.

If there are no cut off areas on the disc

20 lighter arrangement of the plate are formed, the bolts can be rectangular in cross section for non-rotatable guidance, and the head of the bolts is V-shaped in side view. So that the bolts when arranging the plate on the disc through the top

25. Edge of the washer, which abuts the lower inclined surface of the bolt, be pushed slightly backwards so that the washer can be completely accommodated in the recess in the plate. When the plate is pushed all the way down, the bolts can extend out again

30 step out of their channels until they line up with the undercut on the pane. Depending on the formation of the bevel of the undercut as well as the bevel on the bolt head and the prestressing force, the force required to arrange the

35 plate on the disc and to release the binding is required. _First To fasten the shoes of winter sports enthusiasts, locking slits are preferably provided on the plate for inserting retaining brackets. A number of such slots are offered so that the plate

5 can be attached to shoes of different sizes.

In a development of the invention, the disc and the plate are made of reinforced plastic. But it is possible, in particular, the disc made of an aluminum alloy made of Q; to build,. there. due to the attack of the locking bolts of the plate: - there is some wear.

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

Locking elements 20, 22 and 24, 26 are fastened on the base plate 12. These locking elements 20 to 26 are used to attach binding plates 28 and 30, respectively. The plates 28 and 30 are or the like by means of suitable fastening means such as straps. attached to the feet of winter sports enthusiasts. The plates 28 and 30 can also be integrated in the soles of the shoes of winter sports enthusiasts. The plates 28 and 30 together with the locking elements 20 and 22 or 24 and 26 result in fixed or self-releasing bonds.

Fig. 2 shows a plan view of a plate 32 of a bond, wherein the left part represents the ^"plate from below, and the right part of the plate from the top. The elongate formed plate 32 is formed at their narrow sides with recesses or recesses 34. These recesses 34 are used to hold locking elements 40. As can be seen in particular from FIG. 4, the locking elements 40 are approximately keyhole-shaped in cross section and they have lateral fastening legs 42

and 44, with which they are fastened by screws 46, 48 to the sta plate of a winter sports device or on skis. The locking elements 40 are preferably bent from sheet metal. The double-walled narrow central web 50 is used to create heads of locking bolts 52 and 54 which are guided in the plate 32 so as to be displaceable. These bolts 52 and 54 lie under the relatively wide head 56 of the locking element 40, so that movement of the plate 32 upwards is hindered. This movement is only possible if the bolts 52 and 54 can be pushed back against the force of springs 58, which can be achieved by pulling the plate 32 upwards, weaving the bolts on the transition surfaces between the web 50 and the head 56 accumulate.

The bolts 52 and 54 are received in recesses 60, 62 of the plate 32, which are closed on the underside via cover plates 64, 66. The springs 58 are arranged coaxially with the bolts 52 and 54. The bolts 52 and 54 have a slot 68 at the outer end with which they can be rotated. Here, a washer 70, which is provided with an internal thread, slides on an external thread of the bolt 54, so that the length of the spring 58 can be adjusted, which results in an adjustment of the spring force. The A - cover plates 64 and 66 are fastened to the plate 32 by means of screws 72 and 74, respectively.

Blind holes 76 and 78 are provided in the plate from the side, in which suitable elements for fastening the plate 32 to the shoe of a winter sports enthusiast can be arranged. Such elements know belts or bands or the like. his. Corresponding bores are formed at the rear end of the plate. The plate 32 is formed on the underside with Abstar.dselemer.ten 80, so that the plate has only a small surface area on the winter sports device. This prevents the plate 32 from freezing to the winter sports device. On the top, the plate 32 is formed with gur.miaauflagen 82, which for a I better leg position may be elevated on one side.

To use the winter sports device 10, the plates 3 are attached to the shoes of the winter sports enthusiast. The 5 winter sports enthusiast then climbs the stand plate 12 of the

Winter sports device 10, in that the front locking device 20 or 24 is received in the wedge-shaped recess or recess 40 for better threading. The heads of the bolts 52 and 54 lie under the head 56 of the locking element and they slide on the narrow web 50 until the rear end of the locking element 20, 24 or 40 has reached the rear end of the recess 34. Now the winter sportsperson loads the rear end of the base plate with his weight, so that the bolts arranged in the area of the 5 rear recess or cutout rest on the head of the locking element and are pushed back by the head, after which the plate up to is exceeded after the widest point of the head has been exceeded is lowered to rest on the base plate. After passing over the head 56, the bolts can then move out of their recesses and rest with their heads on the narrow web 50, so that the locking of the plate is secured up to a certain size, which depends on the spring force. 5

4. On a plate 90 are starting from the narrow sides

Recesses 92 and 94 designed to receive locking elements, not shown. The plate 90 0 is held on the locking elements by means of bolts 96, the springs 98 in the direction of the locking elements, i.e. are biased towards the recesses 92 and 94. The release of the bolts 96 takes place via a lever 100 articulated at the outer end, which can be in the form of an eccentric 5, or which is used to retract the bolts 96

Approaches LC2 can support on the narrow sides of the Plat 90

Fig. 7 shows the plate 104 of a security tie in its front region as the plates 32 and 90 out ^¬ forms can be. In the rear area, the plate has an elongated hole 106 for receiving a locking element 108 instead of a recess extending from a narrow side. The elongated hole 106 has approximately twice the length of the locking element 108. In the slot 106 are locking bolts 110 and 112 with their heads. The locking ^¬ element 108 is formed as the locking elements 40. The slotted hole 106, a bolt 114 is performed, the

10 has a handle 116 bent at right angles. With the broken line, the handle 116 is shown in the position in which the bolt 114 does not penetrate the elongated hole 106. In this position, the front locking element can be received in the corresponding recess by placing the plate 104 on the winter sports device, the rear locking element 108 being arranged in the front region of the elongated hole 106. By pushing the plate 104 forward, the front locking element is received in the recess and the rear locking element 108 assumes the position shown in FIG. 7. The bolts slide

20 110 and 112 under the thickened head of the locking element 108 on its narrow web into the position shown in FIG. 7. After the plate 104 has assumed its end position, the bolt 114 is guided into the locking position, its inner end lying in front of the locking element 108

25 The handle 116 of the pin 114 is placed in a receptacle 118 formed in the plate.

Figure 9 shows binding with a plate 120 that is not a self-triggering binding. The plate 120 has in its front end a recess 122 with a conical insertion 124. A pin 126 is fastened in the plate through this recess 122. At the rear end the plate has a recess 128 which also widens conically towards the outside. The head 130 of a bolt 132, on which a spring 13 is arranged coaxially, engages in the rear recess 128. The bolt can be pulled out by wasting a lever 136 so that the Koof 1 0 di Recesses 128.

The locking elements 142 and 144, which are fastened on a base plate 140, for example, to lock the plate 120, are designed differently than the locking elements 40 according to FIG. 4. The locking element 142 consists of a block 146, preferably made of sheet metal, which has a recess 148 on the rear is formed, into which the pin 126, which is fixed in the plate 120, can be inserted. The rear locking element 144 likewise consists of a block 150 which is bent from a sheet metal and is formed with a through-bore 152 for receiving the head 130 of the bolt 132. The locking elements 142 and 144 have fastening tabs 154 and 156, arranged at right angles, through which screws 158 and 160 are guided. The top and bottom of plate 120 can be formed like plate 32.

11 shows a plate 170 with locking bolts, not shown in detail. In the area of the rear recess 172 of the plate 170, in which a locking element is received, a release arm 174 is articulated, which is designed with projections 176 and 178. Furthermore, the trigger arm has a handle lever 180 with which it can be pivoted in the clockwise direction. During the pivoting, the lugs 176 and 178 reach the upper side of the plate or a ski, whereby after further pivoting up to the maximum upper position of the lever 180, the lugs 176 and 178 lever the plate 170 from the locking elements. The bolts are pushed back until the reinforced head of the locking element brushes past the bolts. The handle lever 180 is preferably received in a recess 132 in the plate.

If the Mecnanik 14 together with the andtandplatte 12 can be removed from the runners 16 and 13 in the winter sports device according to FIG. 1 and if entsorecher.de on the runners Locking elements 20, 22 and 24, 26 are arranged, after loosening the plates 28, 30 from the base plate 12, these plates can be fastened to the runners with the aid of the locking elements arranged on the runners. It is thus possible to use a drag lift by fastening the runners 16, 18 to the feet of the winter sports enthusiast, the base plate 12 being taken uphill together with the mechanism 14 under the arm of the winter sports enthusiast. After leaving the lift, the plates can be detached from the runners and arranged on the mechanism, after which the device can be used again in the original sense after the binding plates have been reattached to the base plate.

To release the binding in the event of torsional loads, the locking elements in the fastening tabs are formed with elongated holes, through which fastening screws are guided, which allow the locking elements to be displaced. The plates have bevels on the underside of the edges, in particular in the areas in which the locking elements are arranged, and ramp wedges are arranged on the winter sports equipment, ie on the skis or the base plate, which, when the binding is in the normal position, sloping edges. If the leg is twisted in the event of a fall, the plate is taken along by the foot and swiveled, the chamfered edges running onto the wedges. This raises the plate and when a certain height is reached, the 3 bolts in the plate release the locking elements so that the foot is released from the winter sports equipment together with the plate. This reliably prevents twists and turns of winter sports enthusiasts. The elongated holes in the tabs of the locking elements preferably lie on arcs, the center of which coincides with the axis of the main rotary motion of the leg of the winter sports enthusiast. 23 "shows a further embodiment of a plate 184 of a binding. The plate 184 is designed as an elongated rectangle, with recesses being formed in the central region in order to save material. From the front narrow side 5. there is a recess 186 in the plate 184 The heads of bolts 188 to 194 protrude into this recess 186, which serves to receive a locking element (not shown). As in the embodiment shown with reference to FIG. 2, the bolts are loaded via springs 196 to 202 0 and slidable in blocks 204 and 206. In blocks 204 and 206, which are inserted into recesses on the underside of plate 184 and fastened by means of screws 208 and nuts 210, nuts 212 and 214 are guided, through which threaded sections 216 and 218 the bolt 5 The nuts 212 and 214 are displaced by turning the bolts, so that the force of the springs 196 to 202 can be adjusted. Washers 216, 218 are also arranged between the springs and the nuts.

0 ^A t the top of the plate 184 are rubber supports 220, 222 disposed, the nubs 224 have, so that a non-slip grip of the plate 184 is reached to a shoe. The supports 220 and 222 have recesses 226, 228 for receiving transparent plates 230, 232 provided with scales, through 5; which the nuts 212, 214 are visible so that the Feder¬ strength can be read.

An elongated hole 234 is provided in the rear area of the plate 184. The heads of bolts 236 protrude into this elongated hole, the design and arrangement of which are analogous to the bolts described in the front region. The elongated hole is approximately twice as long as a locking element which is arranged on the runner or on the base plate of a winter sports device. To attach the plate 184 to the winter sports equipment, the corresponding locking element is received in the front area in the elongated hole 234 5. After the plate 184 has been pushed forward, the locking elements on the winter sports device reach the area of the front and rear spring-loaded bolts. In this Position, an axis 238 is pivoted, which is arranged on the underside of the plate in front of the elongated hole 234. The axle is pivotably mounted in a recess 240 on the underside of the plate 184 and is held on the plate 184 by means of screws (not shown). In the middle of the axis 238 a formation 242 is formed, which is received in the unlocked position in a recess formed on the underside of the plate 184. After pivoting the: axis 238 counterclockwise by 90 °, the formation reaches a stop arranged on the upper side of the runners or on the base plate of the winter sports device, so that the plate 184 is locked in the longitudinal direction and neither to the rear nor to the rear can be moved forward. The axis 238 is formed with handles 244 and 246 protruding laterally next to the plate. With the help of these handles, the axis 238 can be pivoted. In this embodiment, the binding plate 184 can be attached to the winter sports equipment without any effort, so that the holding position can be assumed by placing and moving the plate 184. The pivoting of the axis 238 does not require much effort

The binding plate 184 is also formed in the rear area with rubber pads 248, 250 and scale plates 252, 254 in order to check the setting of the spring force acting on the bolts and to improve the slip resistance. In the rear area, laterally projecting hooks 256 are arranged on the plate, on which heel straps can be arranged to fasten the binding plate to the shoe of a winter sportsperson. In the front area of the plate, through holes 258, 260 are formed in the plate, through which hooks can be inserted, on which a strap for fastening the toe area of a shoe can be arranged. 14 shows a top view of a plate 310 which, together with a disc 312 shown in FIG. 19, forms a self-triggering safety binding for a winter sports device. The plate 310 is fastened to a shoe of a winter sports enthusiast, while the disc 312 is fastened on the top of skis or on the base plate of a winter sport device designed with parallel swiveling runners.

The plate 310 is in the form of an elongated rectangle with a front edge 314 and a rear edge 316 and 1 longitudinal side edges 318 and 320. A recess 322 is formed in the center of the plate 310, which is circular in the embodiment shown. It is thus possible to rotate the plate 310 in the recess 322 after the disk 312 has been received. This is particularly important, ^" since in the case of the winter sports device with parallel, pivotable runners, the winter sports person stands approximately transversely to the longitudinal axis of the device. By rotating the plate 310 around the disk 312, suitable body positions can be adopted in this winter sports device in order to steer the Device are required.

In the plate 312 channels 324 and 326 are each from the end face 314 or. the rear 316 formed ago. The channels can, as shown in Figure 17, rectangular or round in ^cross' be cut. As can be seen in particular from FIG. 15, which shows a longitudinal section through the channels 324 and 326, a spring 330 is arranged in the channel 326 and its front end

The side abuts against the rear surface of a bolt 332, and its rear side rests against the collar 334 of an adjusting screw 336 which is screwed into an internal thread 338. The adjusting screw 336 is to be provided with a setting scale, so that the force exerted on the bolt 332 via the spring 330 can be adjusted with a screwdriver inserted into a screw slot 340. The bolt has at its rear end a collar 342 which bears against a shoulder 344 in the

1 ^" 0- channel 326 ^" is pending. The head 346 of the bolt 332 is in the

Normally into the recess 322 in order to stand at an undercut 348 which is formed on the disk 312 (see FIG. 20). In the embodiment shown, the bolt 332 has a circular transverse

115- ^* cut open a rounded head 346.

As can be seen from FIGS. 14 and 16, the plate 310 has a cover 350 in the central area around the recess 322, which cover 35 is attached to the plate 310 by screws 352

20. is attached. This cover facilitates the manufacture of the plate 310, which preferably consists of a reinforced plastic, and the assembly of the bolts 332 in the channels 324 and 326, respectively. It is also possible to design the channels 324 _and 326 on the plate 310 as open channels

25; are closed by cover plates 354.

In the embodiment shown, two channels for two bolts each are arranged from each side 314 and 316 of the plate 310. But it is also possible to only have one at a time

30: Align bolts against recess 322 from each side. It is also possible to direct a pin against the recess 322 only from the rear end face 316. In this case, a suitable locking device would have to be used to ensure a symmetrical

35 opposite the bolt between the plate and the washer 1- For fastening the plate 310 to a shoe, locking slots 360 are formed in the course of the front region of the side edges 318 and 320, into which suitably shaped ends of stirrups are inserted, which are secured by a strap

5 are connected. So that the top one

Shoes are firmly connected to the plate 310. In the rear area of the side edges 318 and 320, bores 362 are formed, in which ends of locking bars can be anchored, with which the heel of the shoe is firmly connected to the 10th plate. However, it is also possible to arrange the plate 310 ^" integrated in the sole of a ski boot. In this case, locking slots or bores can be dispensed with.

15 The one attached to the top of the winter sports equipment

Disk 312, which is received in the recess 322 of the plate, is shown in Figures 19-21. The plate 312 is circular and is attached to the winter sports device by means of countersunk screws 366. As can be seen from Fig. 20,

20 the disk 312 is provided on its circumferential surface with an undercut 348 which is in the form of a V with a longer upper leg 368 and a shorter lower leg 370. To make it easier to arrange the plate 310 on the disk 312, it has cut off areas 372,

25 ^" 374, which can be seen in Fig. 21. When the plate 310 is placed on the disc 312, the heads of the locking or release bolts 332 slide on the inclined surfaces of the sections 372 and 374. When the disc 312 is completely in the recess 322 is received, the plate

30 ^" 310 rotated with the foot until the heads of the bolts 332 lie against the inclined surface of the undercut 348. In order to find the correct position of the plate 310 on the disk 312 more quickly, detent seats can be formed in the area of the undercut 348 so that the

35 ^" user is signaled by latching the bolt heads 346 that he has taken the exact position on the winter sports equipment: This is again particularly important for a winter sports device with base plate and swiveling

Runners. Two or three locking positions are then preferably formed, which correspond to the usual positions of the user on the device. When using the safety binding on a normal alpine ski, only two opposite locking positions on the longitudinal axis of the ski are required.

When using the self-triggering safety binding, the plate with its recess

322 arranged around the disc 312. In the event of a fall, i.e. If the winter sports device is to be released from the foot of the sports activity, a restoring force is exerted on the bolts 332 in every position between the plate 310 and the disc 312, so that when a preset force is exceeded, the plate 310 is released from the disc 312 he follows. The safety binding consists of only a few parts, which form a closed system, so that no contamination or faulty triggering from attached ice or attached snow can occur. A striking feature is that the security release can take place in all directions.
