Arrangement for fixing the fastening device for a boot on a ski

The invention relates to an arrangement for laying down the fastening device for a boot on a ski, "consisting of screws inserted into the ski surface, as well as one Base plate with openings to interact with the screws.

Methods have long been known for making certain accessories and even to temporarily attach the bindings to skis. With regard to these procedures, one can quote those one rail or a sliding guide for fixing the base plate for a heel part or for sliding protection devices like seal skins, with the fixing done transversely in relation to the ski, while the securing takes place lengthways must be produced by an auxiliary organ, which the complexity and expense in terms of the cost of the arrangement and its assembly and assembling

sert. In addition, with such a fastening device, the sliding guide mechanically strong forces perpendicular to the Ski must withstand so that they consist of a sufficiently rigid and therefore heavy piece and are intimately connected to the ski must be, which is generally achieved with the help of screws.

It can be seen that the use of such a part between the attachment and the screws introduced into the ski does not represent a rational solution, even if it provides a means of obtaining a longitudinal adjustment facility for adjustment which forms fastening devices on different shoe sizes.

It is the object of the present invention to further develop an arrangement of the type specified in the introduction in such a way that the aforementioned Difficulties can be eliminated and the arrangement can be designed particularly simply and easily attached φ and reliably fixes the fastening devices on the ski.

This object is achieved according to the invention in that the arranged in the base plate and for cooperation with certain openings for the screws are designed so that they can be attached to the base plate after it has been finally screwed in

During the assembly, the screws 3 can be in the position that is in the Pig. 1 and 3 is reproduced. The base plate 2 is then threaded with its opening sections 4A over the heads 6 of the screws 3 and pressed against the surface of the ski 1. Here, the edge areas 9 of the elastic plate 5 are raised. Due to a transverse movement, the base plate 2 can now slide to the right in the figures, the shaft sections 7 of the screws 3 entering the section 4B of the openings 4.

In the embodiment according to the Pig. 5 and 6 has the Base plate has two openings 4 in the form of a buttonhole, i.e. openings with a large section 4A and a narrower section 4B. A cutout or window 10 is provided at one end of the base plate 2, the width of which is substantially the same the width of the section 4B of the openings 4 is. This width is slightly larger than the diameter of the shaft 7 in the unthreaded area of the screw 3.

The end of the base plate 2 in which the recess 10 is provided has a reinforcement to form a shoulder 11 on its surface. Because of this arrangement, the in the usual Y / ice formed screws 3 with cylindrical Head first or from the start are fastened in the surface of the ski according to the arrangement of the openings 4B and the recess 10. The two screws 3, which are intended to engage in the openings 4B, are so far in the ski 1 screwed in that they are between the bottom of their Head 6 and the top 12 of the ski leave a distance essentially equal to the thickness of the base plate 2. The screw 3 ', which is intended to engage in the recess 10, is initially only screwed into the ski 1 as far as that of the thickness of the verctcrkten end 13 of the base plate 2 corresponds. To this Weirje i üt ca possible that subsequently the base plate 2 with the openings 4A is threaded over the heads 6 of the screws 3 and displaced in the longitudinal direction, specifically in the direction of the arrow P. When there is a relative shift in relation to ski 1, step the shafts 7 of the screws 3 in the narrowed portions 4B

the openings 4 of the base plate 2, while the screw 3 ^f at the same time reaches the end of the recess 10. It is then sufficient to screw in the screw 3 'so far that the head comes into contact with the upper side of the base plate 2 in order to lock the base plate on the ski 1. Here, the head 6 of the screw 3 ¹ interacts with the shoulder 11 and prevents any untimely displacement of the base plate 2.

In the two exemplary embodiments described above, it can be seen that a mounting template can be very practical for fixing the head 6 of the screws at the desired height. FIGS. 7 and 8 show such a thin plate 14 having the hollow cylindrical projections 15 yon the desired height, which are intended to partially serve as a guide for the tool for pre-drilling of holes for receiving the screws 3 in the ski 1. At the same time, however, they also have the task of limiting the screwing of the screws 3 into the ski 1 to the desired height, which corresponds to the thickness of the base plate 2. Such a contact plate 14 can also remain permanently attached to the top 12 of the ski 1, the section 4B of the openings 4 of the base plate must have a width that corresponds to the outer diameter of the guide lugs 15, which thus the function of the shaft of each screw 3 in Replace interaction with the openings 4 of the base plate.

FIGS. 9 and 10 illustrate a third embodiment at the base plate 2 in turn openings 4 in the form of button

has holes. The openings 4 have a section 4A with a diameter slightly larger than the diameter D of the head 6 of the screws, while the section 4B has a dimension slightly above the diameter d of the shaft 7 of the screws 3 is located.

During the assembly of the fastening device, washers 16 with a thickness which essentially corresponds to the thickness of the base plate 2 are arranged under the head 6 of the screws 3. Each disk 16 has a laterally or radially directed recess 17 which essentially corresponds exactly to the cross section of the shaft 7 of each screw 3 or is slightly wider. The washers 16 serve to limit the screw depth of the screws 3 to the desired value. Werew. on the other hand, the screws 3 are screwed into the ski 1 and if the base plate 2 with its opening sections 4A has then been threaded over the heads and the washers 16, it is possible to move the base plate 2 in the direction of arrow F due to the presence of the recess 17 to move so that the shafts 7 of the screws 3 enter the section 4B of the openings 4. The base plate 2 can then be locked in relation to the disks 3 by turning each disk 16, for example Be, by a quarter turn in order to prevent the shaft of the screws from sliding back into the recess 17 of the disk 16.

In Fig. 11 i-it shows an embodiment in which the Base plate has openings 4 which have a frustoconical

Open cross-section. The head 6 j el he screw 3, which is essentially is cylindrical, has a circumferential constriction 16 on, in which a spring ring 19 is inserted. The big diameter the frustoconical opening 4 corresponds to the diameter of the spring ring 19 in the expanded position, while the small diameter is the diameter of the head 6 of the screw "be 3 corresponds. The fastening of the base plate 2 takes place Ie.-by, that the frustoconical openings 4 are placed on the screw heads 6. This will put pressure on the Base plate 2 exercised in the direction of the top 12 of the ski 1, around the elastic retraction of the spring ring 19 in to reach the constriction 18. After that, the spring washer is the constricted Has passed section of opening 4, he can alch expand accordingly. In the embodiment shown ;. a recess 20 is provided in the upper region of each opening 4, which is intended to receive the spring ring 19 in the extended Position serves to fix the fastening on the: ^ l: i 1 to hold on.

This arrangement is installed by first screwing the T-piece 21 into a central area of the upper side 12 of the ski 1. The device for attaching the boot to the ski is then attached to the ski by placing the base plate 2 in a transverse position with respect to the ski 1 so that the section 23 of the T-piece 21 engages through the opening 24.

It is noted that the height of the foot section 22 is essentially exactly the same as the thickness of the base plate 2, the pufi section 22 having a circular cross-section with a diameter corresponding to the width of the opening 24. It can be seen that it is then sufficient to rotate the fastening device about the foot portion 22 by approximately 9C in order to fix the base plate 2 on the ski 1, specifically in the direction perpendicular to the surface 12 of the ski. One can subsequently the fastening device, which is represented by the base plate 2 in ■ Jen drawings, move on the ski 1 in the longitudinal direction and within the limits of the length of the opening?. 4 The final definition of the fastening device can a ;.
