"Device for attaching a ski boot to a ski"

The invention relates to a device for fastening a ski boot on a ski, consisting of a device with holes provided base plate, through which screws can be screwed into the surface of the ski.

There are already several types of such devices (front abutment, rear jaws) known, which generally have a base plate which is provided with holes is. These are used to ensure that screws' can be passed through the holes to facilitate the assembly and the fixing of the Device to allow on the surface of a ski.

In general, the fastening devices or bindings are supplied in appropriate packaging in which the fastening screws are packaged separately. When mounting the device on a ski, it is therefore necessary, "after careful drilling of VorXb'cbenj in Ski

'-individually And by hand the screws in the associated Insert holes and keep the screws aligned while screwing them in. Such a process offers no particular difficulty in the case where a single Binding must be mounted. However, this no longer applies if a large number of skis are equipped with bindings must become. Other major difficulties are the risk of one or more screws on the Get lost in transport or if the screws are twisted, as they are often different for the front abutment or the rear jaw.

It has already been proposed to deliver the fastening devices in the packaging so that the screws in their position are held by the fact that they have been wedged into the associated hole as a whole, namely with the help of a cardboard plate cheas. Me outer parts of the Screws that protrude from the base plate grip the cardboard plate and are held by it wel.cbe the screws h in. Such a solution proves however, it is not found to be completely satisfactory, since the assembly of the device requires to remove the cardboard plate beforehand, which is a little more convenient and simple process and involves the risk that

409824/0775

sieve the screws free undesirably so that they fall out of their holes and get lost.

It is an object of the present invention to overcome these various problems and to provide a device which is mono-, is economical to manufacture and can be held with the aid of the screws reliably in their place and the v / eiterbin much assembly work in the attachment the device on the ski facilitated.

This object is achieved according to the invention in that the base plate is provided with a deformable member with respect to each individual hole which presents a central bore of a diameter which is essentially the same as that of the screw, and in that the mounting screw engages in and in the bore is held, wherein the deformable member is fixed against rotation, such that it does not rotate _s when the screw is screwed into the member.

The organs made of deformable material ensure that the screw is reliably held zv ^ angled in the form of a disc or a bush made of plastic or sheet metal or some other

malleable material. The washers or bushings can be completely received in the holes. But you can only partially intervene in the holes. she but can also be arranged on the outside of the bores so that they come to lie coaxially with the bores.

The invention offers the advantage that the screws are reliable be held in their holes and caicht can loosen, even in the case of significant vibrations during transport. In addition, the deformable organs attack the screws partially and the Screws are held in such a way that their tips are below the base of the fastening device protrude so that they are in correct axial alignment can be engaged with the pre-drilled or prefabricated holes in the ski.

Due to the fact that the deformable organs that hold the screws are permanently connected to the base plate of the fastening device and do not form annoying protrusions on the underside of the base plate, the fastening device can then, when it is removed from its packaging, as it is be mounted on the ski, without any a3 &-% a * B. nian piece must decrease, a plaster board or the like., 'which offered during transport

"is needed. Once the screws are screwed into the ski are, the holding organs play from deformable Material also has the beneficial role of a brake to prevent the screws from loosening. So you wear contributes to the complete immobility and fixation of the screws.

The invention is explained in more detail below with reference to schematic drawings of several exemplary embodiments.

In Pig. 1 is a rear binding part 1 of known type shown, which is only indicated schematically and a Has base plate 2, with the help of which the binding part rests on the surface of a ski and is attached. Such a binding part is in the usual way on the ski with the help of four screws, d. n. two rear screws 3 and two front screws 4 attached, the front Screws are shorter than the rear ones. Each pair of front and rear screws is symmetrical, respectively with respect to the longitudinal plane of symmetry of the binding part 1 arranged.

Each rear screw 3 engages in a hole 5 which is provided in a side flange 6 which is integrally connected to the binding part. Each front bolt 4 engages through a hole 7 _S provided in a slider 8 which is provided under the front portion 9 of the binding element 1, v / hich region forms a sliding guide. Part of this area is placed under the heel of the ski boot. For this purpose, the screw 4 protrudes through an elongated window in the sliding guide 9, so that an adaptation to the length of the shoe is possible. According to the invention, holding members 11 are trad 12 made of a deformable Ißmaterial each inserted into the bores 5 and 7 to the fastening screws 3 and 4 in other position

It is seen in Fig. 1 that the Beiestigungsscbraub 3 or 4 partially in the stanchions 5 and 7 and the retaining bushes 11 and 12 engage in such a way that only the tips protrude under the base plate 2. This allows one raacne assembly and alignment on the ski. For this it is only necessary to blind the binding part or to have a special one iVufiuerkaasksit to put on the ski as the Tips of screws. That protrude, sieve automatically and immediately insert it into the pre-drilled stanchions of the ski, which are intended to accommodate the screws ". On the other hand can then, if the tip of a screw is guided, screwing is done with screw machines.

made of plastic UBd 'the base plate 16 is arranged «, Zuia difference of the known Yorricbtungen that a plate made of Kartor! have which must be removed prior to assembly , the plate 26 is arranged so that a single lial is mounted for the duration and remains after the attachment of the binding part. To. For this purpose, the screw 2 o is only partially inserted into the disk before screwing it tight so that the tip protrudes slightly downwards.

In order to prevent the bushing or washer from becoming dependent with the eye screw turns, for example if one screwing in the screw begins to get it into the Introduce the front hole of the ski "suitable means are provided the one rotation of the bushing or the washer with respect to the bore; in which it is inserted not to allow

For example, the frictional resistance of the eyelet in the wall of the bore in which it is inserted, selected be that even when screwing the screw into the bore of the socket, the socket opposite the wall of the Bore remains firm. In other words, the coefficient of friction of the bushing in relation to the end of the hole in the it is inserted must be higher than the coefficient of friction of the screw in the socket.

on the other hand, the socket can have a rectangular or rectangular shape non-circular), e.g. polygonal cross-section have 9 'of with a corresponding iOrm of the bore cooperates to prevent rotation of the bushing "

In general, the bushing may contain one or more Element®, bores or Torsprünge or the like having ₀ ;, with ent speaking elements in the base plate as ¥ orsprrägen ₉ holes, etc = cooperate.

In order to ensure that a holding element rotates in it, the arrangement can also be made so that the screw axis does not coincide with the axis of rotation of the holding element. In other words, the arrangement can be such that the screw axis is in relation to the axis of the Halt @ orgaa®s _? which coincides with the axis of the recess, is arranged eccentrically «,

Regardless of whether the holding organ is deformable in its own right, as in the case of the examples described above, 'each organ, which can also consist of a relatively rigid material, can present one or more recesses which offer the organ a certain possibility of deformation' _o example, may consist of one with! windowed cylinder collar or the holding member, which can yield aaßen when a screw wirdο out into the central channel
