Ski tie and ski boot ties

FIELD OF THE INVENTION

The subject of the invention is ski lacing and ski boot ties, in particular alpine skiing.

A technical problem

A technical problem solved by the invention is how to design such a ski binder and ski boot ties, which will provide a rigid base for the ski boot binding and at the same time suppress the transmission of the oscillations (vibrations) of the ski resulting from slips, especially on the hard and uneven snow and ice, with minimal impact on ski characteristics and easy and affordable.

The prior art

Several ski binders and ski boot ties are known. They differ in elastic elements that dampen the vibrations of the skis. However, they are similar in that the binders are fixed at both ends to the ski, while the shoe tie is screwed onto the upper plate of the binder. For the sake of value, we assume that only one type of such embroidery is made with regard to its length, that is, for all shoe sizes and ties. The distance between the screw attachment of the linker to the ski and the attachment of the shoe tie on the upper plate, which increases with decreasing shoe length, causes an additional bending effect on the upper plate of the linker, which reduces its desired rigidity. The rigidity of the top plate is

25576 / D16-lX-96.

desirable in order to provide equal force of shoe attachment in all conditions of the ski during skiing. Namely, when bending this plate, the head and the heel of the ligament break apart and approach, which reduce or increase the manually adjusted force at which the ligament is intended to release (open) the shoe.

Another major disadvantage of all the binders described in this regard, which arises from their length, which is intended for the largest shoes and therefore for the longest skis, is that it occupies a relatively long section in the middle and short skis, thereby shortening the section. free-swinging tips and tails of skis. The closer the point of attachment of the linker to the tip or the fifth ski, the more rigid the linker (despite the elastic inserts) influences the properties of the tip and tail of the ski not only in terms of the desired damping oscillation, but also in terms of the unwanted change in the elasticity of the ski, as intended by the manufacturer.

The obvious solution to this problem by creating a family of dimension-bound binders to each ski boot number and dimension-different bindings is too expensive. The technical advantages would not outweigh the higher price, which, in addition to the large number of midfielder sizes, is compounded by the increased costs due to increased inventory from dealers and repairers.

Therefore, it is the only sensible link that can be easily adjusted in terms of the shortest possible length with regard to the respective length of the shoe and ties so that the effect of the rigidity of the linker on the ski due to its points of attachment to the ski is significantly reduced.

The solution to a technical problem

The solution to the technical problem solved by the invention is that the binder is made of three-part, from the middle hollow flat profile, which is intended to install any bond for the shoe, and two, preferably identical fasteners, which also include inserts for damping oscillations ski. The flat profile of the midfielder is lengthwise adjusted to the respective length of the shoe and ligaments in the process of mounting the midfielder and ligaments to the ski. Only fasten the fasteners without tools or fasteners to the front and rear ends of the flat profile. We attach the completed embroidery to the ski. Then the embroidery is suitable for mounting the embroidery in a known manner.

25576 / D16-IX-96.

The flat profile is preferably hollow in order to reduce weight and to allow the cross sections of the brightness of the two ends to be directly attached to the fasteners without additional treatment.

In order to prevent the snow from entering the gap between the flat profile and the ski and to increase the rigidity of the profile, it can be made as a U-profile with a hollow cross-section having the same function as the previously described flat profile. The lateral free bands, which reinforce the profile, are pointing downwards and surrounding the lateral surfaces of the ski. The ski can be made on this side with the flat side recesses in which the side bands of the profile lie. This holistic design solution enhances the aesthetic appearance of the ski with the brackets and eliminates the unwanted resistance that can be caused by the side straps that pray from the plane of the ski's side surfaces in deep snow.

The fasteners include elastic interfaces through which the fasteners and the flat profile are connected to significantly reduce the transmission of the ski vibrations to the flat profile and thus to the shoe and the skier.

In this way, we produce only two semi-finished products: a flat profile and a fastener, which are available in hardwoods and repairers individually. When mounting the bindings, cut the flat profile to a size appropriate to the length of the shoe and the bindings, and insert the binder in the opening, thus making the binder ready for mounting on the ski and then suitable for fixing the binder.

The elastic bridging insert in the fastener has any damping characteristic. The multi-part design described here makes it easy to manufacture and optionally assemble a bond with different damping characteristics.

The invention will be explained in more detail by the description of two embodiments shown in the accompanying drawings, in which FIG. 1 perspective view of the midfielder after the first embodiment and in the spaced state;

FIG. 2 is a perspective view of the linker according to another embodiment and in a spaced state;

FIG. 3 is a longitudinal cross-sectional view of a portion of the linker along line III-III of FIG. 2; and FIG. 4 is a cross-section of a flat profile after the third embodiment mounted on a ski.

The first embodiment

According to the first embodiment, the ski and shoe linker consists of a flat profile 1 which is intended to be mounted on the pictures of the non-shown shoe bond and two fasteners 2 which are provided for mounting on the ski A, with profile 1 and the fastening elements 2 are jointly interconnected.

Flat profile 1 is preferably a hollow profile due to weight reduction of the entire object. The thickness of its wall is such that the screws of the bonds reach the prescribed breaking force. The openings 3 made at the front ends are provided as a bearing for the attachment elements 2 described below.

The fastening elements 2 are made as low short flat elements of at least three layers: the lower layer 4, which is intended to be supported and directly attached to the ski A by screws 5 lying in the holes 5 ', further to the middle damping layer 6, which is elastic and is designed to dampen the oscillations of the ski and the upper layer 7, which is extended to the side of the tongue 8, which is intended to be tightly seated into the front opening 3 of the flat profile 1. An elastic ring 9 is provided on the tongue 8 to ensure a close contact of the profile 1 and element 2.

The height of the fasteners 2 or their tongues 8 is such that it determines the prescribed maximum permitted distance between the sliding surface of the ski and the upper surface of the linker on which the tie or shoe is mounted. There is a free slot under the flat profile, which can be filled with a lightweight insert to prevent snow accumulation.

The middle damping layer 6 of the fasteners 2 is preferably rubber but may be made of any elastic material. The damping layer 6 is positioned between the lower layer 4 and the upper layer 7 so as to attenuate the oscillations of the ski regardless of the direction of action of the forces causing the oscillations. All three layers of fasteners 2 are bonded to one another by vulcanizing or bonding.

The fasteners 2 are designed to allow any exterior design without reducing the useful features described. Preferably, wedge designs are used to reduce snow accumulation on and before or after them.

Another embodiment

The second embodiment of the linker of the invention is made of the same flat profile 1 with front openings 3 as described in the first embodiment. The fastening elements 20, which are also provided for mounting the linker on the ski A, are made as a U-profile. The lower free lane 21 of the element 20 is provided for mounting and mounting to ski A. On the contrary, i.e. the upper free belt 22 is lengthened by the tongue 23, which is intended for installation in the opening 3 of profile 1. In the upper belt 22, larger holes 24 are made through which the fastening screws 25 are provided, which are located in the holes 26 made in the lower belt 21. .

On the tongue 23, an elastic element 27 is fitted, which fits into the opening 3 of profile 1. The element 27 is designed as a ring with an outer edge 28 lying between the profile 1 and the connecting element 20. This ensures contact between the flat profile 1 on which the shoe is fitted, and the fasteners 20 only via an elastic member 27 that dampens the oscillations of the ski regardless of the direction of the force causing the oscillations.

Only by changing the elastic element 27 with another that has a different oscillation damping characteristic can the tailor parts be adjusted to individual needs in a simple and inexpensive way. The other utility advantages of the second embodiment are the same as those of the above, i.e. easy and inexpensive shoe length adaptation of the shoe length, minimum number of different components in stock from both the manufacturer and the dealer and repairer.

Third embodiment

The third embodiment of the linker is made of fasteners 2 or 20 according to the first or second embodiment. Otherwise, a flat profile 30 is made in terms of a U-profile whose transverse belt 31 is hollow so that it can accommodate at its ends fasteners 2 or 20. The lateral bands 32, which increase the rigidity of the profile, are directed downwards to arm the middle one. part of ski A. Ski A may be made at this point by the lateral flat recesses B, in which the lateral belts 32 lie, give a preserved external lateral contour of the ski and do not represent additional resistance especially in deeper snow.

25576 / D16-IX-96.

Both described embodiments of the invention are practicable in a known technological manner. The flat profile is the simplest and cheapest in batch production as an aluminum or plastic extrusion profile. It is advisable to make fasteners or their metal parts from known profiles with additional processing. In the first embodiment, both metal parts are bonded to the rubber intermediate elastic layer by vulcanization, and in the second embodiment, a particularly elastic element is made in a known manner, which is manually mounted on the tongue of the fastener during ski mounting.

It will be appreciated that one skilled in the art can, with the knowledge of the disclosed essence of the invention, also conceive of other embodiments without departing from the features of the invention defined in the appended claims.
