Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an integral joint for cross-country skis. More precisely, the invention provides cross-country ski boots with cross-country ski boots.
Concerning an integral joint for connection to skis, which provides longitudinal and lateral guidance and fixation of the boot to the ski without the need for continuous attachment during lifting of the boot from the ski. It can be carried out.

[Prior Art] Suitable mounting joints with adjustment systems consisting of specially shaped soles and/or heels of cross-country ski boots are attached to or embedded in cross-country skis in cooperation with plates. things are known.

In particular, devices are known in which one or more longitudinally substantially parallel grooves in the soles of cross-country ski boots cooperate with corresponding ribs in their plates.

These known types of devices have been developed to keep pace with advances in cross-country ski technology and have been established with recent cross-country ski steps.

Among the cross-country ski steps that are of great interest to both amateurs and professionals, there is the so-called skating step, which has many advantages.

This step is carried out in such a way that directional movements on one ski are carried out alternately, while propulsive movements are carried out on the other ski, which extend at an angle to the direction of forward movement and between the skis. The apex of the angle is located at the rear end of the ski, and this step consists of a sliding body of a predetermined length directed toward the outside of the ski track.

The name of this so-called skate step is skating,
To be precise, it is derived primarily from the steps used in the propulsion phase, since the movements are similar.

However, in a skate step, by controlling the ski longitudinally and at the same time properly fixing the boot and ski, the angular lateral thrust is fully transmitted to the ski, thereby increasing stability and speed. It is necessary to be able to do so.

The embodiment described in Swiss Patent No. 619147 is neither able to completely and precisely transmit the thrust nor to precisely control the ski.

U.S. Patent No. 3.907.319, U.S. Patent No. 4,23
However, the joint embodiments disclosed in No. 452 and DE 26 26 309 are not sufficient on their own to provide lateral control of the ski, but are only sufficiently effective for alternating steps.

The joint disclosed in U.S. Pat. No. 4,082,312 provides lateral control of the ski only when the heel is on the ski and there is no snow between the boot and the ski. be able to.

The joints disclosed in West German Patent No. 2,937,347 and French Patent No. 2,443,853 are effective for lateral control of the ski, but they allow snow to get between the boot and the ski, thus causing the boot to stick to the protrusion of the ski. Problems occur when it is not fixed properly.

The fixing device for the sole of a cross-country ski boot disclosed in Italian patent application no. It consists of a groove and a corresponding inset projection provided in the plate which is part of the plate, the groove widening towards the heel of the boot, the apex of the groove being approximately at the bridge of the tip of the boot. It is located between the mounting part of the ski and the toes of the skier's foot. This embodiment provides good lateral control of the ski, but only when the boot is resting on the ski, and if the boot lifts due to a stepping motion, the guide is stationary on the ski. The boots are guided only at the connection points,
This is not done well because there is always a risk of snow getting between the sole of the shoe and the ski.

Italian Patent Application No. 83374 A/86 discloses a toe cap for a cross-country ski boot in which the sole of the boot is shaped as desired and a groove for receiving a replaceable elongated member is provided in the boot. It is located on the lower front part of the. The elongated member is mounted for swinging within the groove about a pivot that is located under the toe of the skier's foot. In this embodiment, the attachment is formed elastically and is able to pick up and return thrust while at the same time providing a good lateral fixation between the toe cap and the boot, so that it is suitable for cross-country skiing. I was able to improve the usage.

All of these examples are unsatisfactory for several reasons. They require the provision of several protrusions on the upper surface of the ski that cooperate with grooves in the sole of the boot. Such protrusions present a major problem, not only in terms of cost, installation and maintenance, but also in the fact that the sole of the shoe becomes disengaged from its guide when subjected to the strong lateral thrusts that occur in the case of skating steps; As the guides are fixed to the ski, they are useless when the boot is lifted off the ski.

In the case of Italian Patent Application No. 83374 A/86, the device proposed therein is not actually suitable for long-term use on skate steps, so lateral control has to be supplemented by other means. There is.

Even in cases other than those described in Italian Patent Application No. 83374 A/86, lateral control has to be supplemented by other means, since the ingress of snow causes problems in engagement and proper use.

In addition, conventional devices include weight, size and overall volume;
There are general and individual problems associated with installation and maintenance difficulties, replacement of fixtures and matching with desired steps.

Therefore, modern cross-country skis have a variety of devices consisting of boots and corresponding fittings, the characteristics of which perfectly combine athletic movements and effective operation of the equipment, improving overall performance. The aim is to

However, with the introduction of the skate step, motor skills have outpaced the device's response.

Although improvements and design changes have been made to the device to enable it to adapt to new requirements, it has not yet been able to fully respond to technological advances.

As a result, there are no products on the market designed based on new concepts that can adequately meet these new demands. The central problem to be solved is to be able to guide the boot in all states of athletic movement.

In all conventional joints, the boot is attached to the joint at the toe joint and is guided by a projection that is fixed to the ski and fitted into a corresponding groove in the sole.

These protrusions can only provide good guidance when the boot is pressed against the ski during sliding, and when the boot is lifted during propulsion or skating steps, a strong lateral thrust is generated that forces the foot to Torsional forces are applied, causing the sole to disengage from its guides and subjecting the joint and boot to strong stresses that deform and/or break them.

Furthermore, advances in materials tend to make skis increasingly lighter and therefore more prone to breakage, especially at the point where the joint is attached to the ski.

It is generally known that all joints are attached to skis with three screws, the screw holes of which are of standard size. If you want to replace the joint, you have to unscrew it and then retighten it, which weakens the ski by enlarging the screw hole in the location of the most stress.

A special adhesive must then be used to securely fix the joint to the ski.

There is also the fact that special joints are only effective for specific shoe soles, creating problems of incompatibility between existing devices.

Additionally, conventional joints and guides are for specific boot sizes. If the size of the boot changes, the problem arises of fitting guides to the boot or replacing them.

Therefore, there are no joints that would allow the sole to be adapted to various systems through special miniaturization.

Overall volume is another factor that cannot be overlooked. Since conventional joints protrude somewhat beyond the toe of the boot, and sometimes even to the sides of the ski, functional problems arise as the entire mechanism is susceptible to snow and ice intrusion. .

The applicant attempts to overcome all the drawbacks of the prior art and propose new advantages that will become apparent from the following description,
Accordingly, the invention has been designed, tested, and illustrated.

The integral joint for cross-country skiing according to the invention is characterized in that the solution concept is set out in the independent claim, while the dependent claims indicate modifications of the solution concept.

SUMMARY OF THE INVENTION In accordance with the present invention, the drawbacks associated with the prior art are overcome by allowing the joint to swing by extending a support portion to the lower front side of the sole of the boot. This support extends especially to the underside of the sole of the boot.1. It is housed in a hollow space in the sole of the shoe.

The support may be fixed to the ski or may be removable, for example by removing suitable attachment means.

The support is provided with two vertical side members in the longitudinal direction on the underside of the boot, which provide lateral guidance and support functions.

The side members have supporting rocking pivots that are generally parallel to the surface of the ski and perpendicular to the longitudinal axis of the ski.

The relative longitudinal position of the rocking pivot with respect to the tip portion of the boot determines the optimal placement for skating steps, alternating steps or something intermediate between these two contrasting steps.

The swing mounting portion is fitted to swing around the swing pivot. It is generally L-shaped and extends vertically at the front of the boot and horizontally at the underside of the boot, and is housed in a seat in the sole of the boot.

In front of the rocking pivot, the rocking mount has a front tip portion that supports the tip of the boot. This front support portion rises above the upper surface of the ski and forms a support for the sole of the boot.

On the front support part, the block is hinged,
This is elastically pressed and serves to hold between it and the front support part the main fixation pin which is in the front position of the boot and is integral with it.

Spring means cooperating with the surface of the ski or support and possibly also with the front support part are provided so as to be able to resiliently resist rocking of the rocking attachment.

The front support portion is the front end portion of the front member of the swing mounting portion.

At a rearward position of the rocking pivot, at least one rear member is provided which is hinged to and forms part of the front member of the rocker mounting. This rear member elastically resists rocking relative to the front member.

The rear member is provided with an inclined slit, and the seat at the end of the slit holds a secondary fixing pin that is fixed to the sole of the boot parallel to the main fixing pin, and the secondary fixing pin is fixed to the sole of the boot. It is successfully inserted into the seat section below.

The primary and secondary fixing pins may be connected to each other and their connecting portion may be embedded in the sole of the boot.

The slit is sloped away from the rocking pivot as it approaches the surface of the ski.

A rear member may be further provided after the rear member.

When the sole rotates the rocking attachment about the rocking pivot, the rear member rotates about its own pivot and forces the secondary fixation pin towards the primary fixation pin, thereby causing the boot and attachment to rotate. The fixation state of the is improved.

According to the modified example, the problems associated with application of the above embodiment are as follows:
The problem is solved by making it possible to swing the rear member relative to its inoperative position not only upwards but also downwards in a vertical plane. Its inoperative position can be secured by spring means.

By making the rear member swingable downward and by providing an inclined introduction surface in the inclined slit, if the main fixing pin is fitted first, then the secondary fixing pin can also be fitted by simply placing the boot on it.

According to a further variant, the inlet ramp is also provided in the inclined slit, but the elastic thrust member is provided in cooperation with the rocking pivot, and the straight or substantially straight slide of the rear part is provided. This ensures that the movement is within the range of elastic resistance.

In the case of the first embodiment, the rear member can swing downward during connection by overcoming the relative elastic thrust, but in the case of this modification, the rear member also slides backward during connection. can return elastically.

Taking into account the possible failure of the rear member due to the stresses that it has to undergo, the present invention provides for extending the front part of the rear member to be located between two wings formed on the front member. It has a structure that allows it to come out.

According to a further modification, the extension of the front part of the rear member is
The structure cooperates with an elastic member that elastically presses the rear member towards the ski.

In a further modification, the rear section of the rear member is configured to cooperate with a guide member that prevents lateral rotation of the rear section.

A suitable connection is provided between the rear part and the guide member to allow free vertical but not lateral movement of the rear part.

According to a further modification, an integral guide is provided by the invention which cooperates with the sole metal body. This body shape guide is
It may be fixed or adjustable in length to accommodate different sizes of ski boots.

The present invention will now be described in detail with reference to the accompanying drawings.

A joint 10 is mounted above the upper support surface 35 of the cross-country ski 34. joint 10
has a support 11 with a side member 36 located conveniently in a hollow 19 provided in the sole 18 of the boot on the underside of the boot.

A first swing pivot, that is, a main auxiliary pivot 12 is provided at the tip of the side member 36, and a swing mounting portion 2 is attached to this.
6 is attached so as to be able to swing on a vertical plane in the long direction of the ski 34. The side member 36 is attached to the swing mounting portion 2
It also serves as a lateral guide for 6.

The swing mounting portion 26 is substantially L-shaped, with the apex of the L substantially aligned with the axis of the main swing pivot 1-12.

In the illustrated embodiment, the pivoting mounting portion 26 comprises at least two members: a front member 27 mounted pivotably about the pivot pivot 12; At least one rear member 2 attached to the second or secondary pivot pivot 37
It consists of 9.

The front member 27 has a front portion 127 extending substantially perpendicular to the ski 34 and a lower portion 227 extending substantially parallel to the ski 34 .

The rear member 29 is attached at its terminal end to the lower portion 227 of the front member 27.

The rear member 29 has an inclined slit 3o on the upper side,
It moves away from the main auxiliary pivot 12 as it approaches the upper support surface 35 of the ski 34.

A seat portion 39 for receiving the sub-fixing pin 21 is formed at the inner end of the slit 3o.

A thrust spring 31 is arranged between the front member 27 and the rear member 29, which pushes the front and rear members 27.29 onto the ski 34.
and is intended to be held in position in alignment with and cooperation with the upper surface 35 of the.

Instead of providing the rear member 29, the front member 27 may be provided with an elastic extension, and the seat portion 39 for receiving the sub-fixing pin 2I may be formed in this extension. That is, the front member 27 and the rear member 29 may be formed of a single piece with an intermediate elastic portion that allows at least the rear member 29 to move vertically relative to the front member 27.

As mentioned above, the front member 27 is swingably supported by the swing pivot 12, and the side members 36 of the support section
The sides are guided by.

The longitudinal position of the rocking pivot 12 relative to the toe cap of the boot 17 determines the type of preferred step to be performed. Examples of various positional relationships are No. 13a and No. 13b.
and FIG. 13c.

The rocking pivot 12 can also be arranged further forward or backward depending on the particular step in which the particular assembly is preferred.

By exchanging the support 11 together with the corresponding rocking attachment 26 or just the rocking attachment 26, the preliminary arrangement of the skis 34 can be quickly changed.

In this way, the 13a with the swinging pivot I2 provided in the front
The arrangement shown is suitable for alternating steps, whereas the arrangement according to FIG. 13c, with the rocking pivot 12 rearwardly located substantially below the boot 7, is suitable for skating steps.

As described above, in this embodiment, the seat portions 19 are provided on the front and lower sides of the sole 18 so as to cooperate with the main fixing pin 20 and the sub fixing pin 21, respectively.

In this embodiment, both the main fixing pin 20 and the sub fixing pin 21 are inserted through the seat portion I9, and the boot 17 is attached to the joint 10.

A solid side connecting member is connected to the main fixing pin 20 and the sub fixing pin 21.
and the fixing pin 20 embedded in the sole of the shoe ■8.
．． 21 and the tip of the sole 18 can also be reinforced.

The front end portion of the front member 27 rises to form a front support portion 28, and a sole 18 on which a first seat portion 19 is provided.
The front part of is in contact.

Front part 1 of the front member 27 in which the front support part 28 is arranged
A second seat portion 25 for receiving the main fixing pin 21 is provided at a high position of 27, and a second seat portion 25 for receiving the main fixing pin 21 is provided at a high position of the second seat portion 27.
is fitted into an inclined slit 30 of the rear member 29 or, in the above-described variant, into an elastic extension of the lower part 227 of the front member 27. A portion of the second seat portion 25 is a front support portion 28
Also, it is partially formed by a block member 22.

The block member 22 is elastically pressed against the front support portion 28 by a second thrust spring 32, and the swing mounting portion 26
The front member 27 is supported by a front portion 127 of the front member 27 so as to be able to swing about the third swing pivot 23 .

The block member 22 is therefore supported by the front member 27 via the third catch pivot 23.

The actuation notch 24 provided in the block member 22 allows
The blocking member 22 can be rotated about the third catch pivot 23 to apply a force that opens the second seat portion 25 and releases the main fixation pin 20.

Spring means 33 are arranged at least on the front portion 127 of the front member 27.
and is arranged between the support part 11 and its front part 127. In the illustrated embodiment, these spring means 33 are thrust springs made of elastic material and rest on the bottom of the support 11. In this case, they act against the front member 27 and the block member 22.

The support part 11 has a fixed toe cap 1 at its distal end.
4, the toe cap 14 also serves to support the thrust spring 33 against it.

By removing the thrust spring 33, the screw 15 that fixes the toe cap 14 in this embodiment can be accessed.

If the toe cap 14 is removed, the support part 11 can be moved forward in the longitudinal direction and pulled out. In practice, the support part 11 has a coupling plate 16 at its rear part,
This is secured by screws or other means to the upper surface 3 of the ski 34.
5 is inserted into the third seat portion 38 formed by the positioning member 13 fixed to the positioning member 13 .

The connecting blade 16 can also be embedded into the ski 34 during manufacture of the ski to obtain the third seat portion 38.

In this embodiment, the side members 36 of the support portion 11 cooperate with the upper surface of the positioning member 13 when the entire body is attached and fixed.

The precise positioning of the third seat part 38 and the connecting blade 16 allows a very precise lateral mounting, while the longitudinal mounting can also be carried out with screws 15 tightening the fixed toe cap 14. .

The rear member 37 that can swing around the sub-swing pivot 37 is
As mentioned above, the thrust spring 31 is disposed on the rear side of the lower portion 227 of the front member 27, and the thrust spring 31 is disposed on the rear side of the lower portion 227 of the front member 27.
acting between.

When the boot 17 is on the ski 34 and is not operating in a vertical plane (see FIGS. 1 and 2), the front member 27 rests on the support 11 and the rear member 29 is in this case It rests on the upper surface 35 of 34.

The sole 18 with a seat or hollow part 19 rests on the front support part 28 and on the front and rear parts 27.29, while in this example the lateral parts also rest on the ski 34. (Figure 3).

The rear member 29 (the fourth
(see figure) increases slightly.

When the rear member 29 rises, the seat portion 39 moves and the second
Since the center-to-center distance between the seat portion 25 and the seat portion 39 in the slit 30 is to be reduced, the secondary fixing pin 21 is further tightened within the seat portion 39 in the slit 30.

In this manner, when the boot 17 rotates in the vertical direction, the seat portion 39 of the slit 30 that receives the secondary fixing pin 21 attempts to approach the second seat portion 25 that receives the main fixing pin 20.

In this way, the installation and fixation of the boot is better,
Furthermore, the front and side portions of the boot 17 are better engaged.

As the boot 17 continues to rotate vertically (see Figure 5)
, while the front member 27 also rises, the thrust spring means 33
In order to overcome the resistance force within the elastic range, the front support portion 27
goes down.

To remove the boot 17, remove the sole 18 from the ski 34.
By applying force to the actuating notch 24, the second seat part 25 is opened, and the boot 17 is pulled out in the vertical direction. Leaving 39.

If it is desired to remove the joint 10, in this embodiment, the thrust spring 33 is removed, the screw 15 is removed, the fixed toe cab 14 is removed, and the support part 11 is pulled out together with the swing mounting part 26 thereon.

Therefore, it is easy to replace the joint 10 with another joint in which the main rocking pivot 12 is located further forward or rearward than the previously used joint.

Attaching and detaching the thrust spring means 33 is a very simple and easy task.

For example, the rear member 29 is further provided with a rear member, each of which is fixed to the front rear member, each of which is provided with an inclined slit 30, and each corresponding sub fixing pin 21 is provided with an inclined slit 30.
By cooperating with the boots 17, the entire body can be assembled
Modifications are also possible that allow more control over the

As an example of a modification of the moving means, the rear member 29 may include a rear extending portion 46.
It is also possible to provide a ski 34 and keep it spaced from the upper surface 35 of the ski 34 (FIGS. 6, 7 and 8).

By providing an elastic member 45 on the extending portion 46 and placing it on the upper surface 35 of the ski 34, the extending portion 46
is held in the inoperative position.

Located on the rear upper side of the inclined slit 30, the sub fixing pin 21
causes the extension 46 to cooperate with an inclined surface 43 located substantially above its final position in the seat portion 39 of the inclined slit 30 .

With this improvement, the main fixing pin 20 is inserted into its seat, and then the boot 17 is placed on it and the secondary fixing pin 21 is pressed against the inclined surface 43, overcoming the elastic resistance of the elastic member 45 and extending the extension part 46. By rotating downward,
The sub-fixing pin 21 can be fitted.

When the secondary fixing pin 21 enters the seat portion 39 within the inclined slit 30, the extension portion 46 elastically returns to the inoperative position.

As a second refinement, the rear part 29 can be provided with a forward extension 44 that cooperates with the seat part 48 of the front part 27.

As a result, when a lateral torsional stress is applied to the rear member 29, only a portion of this stress is applied to the sub-swing pivot 37, and most of the stress is applied to the seat portion 48 of the front member 27.
and the forward extension 44 of the rear member 29 onto the lateral support surfaces.

The front extension 44 has a vertical shape so that the rear extension 46 of the rear member 29 can be moved upwardly as desired.

According to a further refinement, the front extension 44 is also provided with second elastic means 40 supported on the upper surface 35 of the ski 34. These second elastic means 40 can keep the rear member 29 inactive.

Another refinement that allows the integral joint 10 to be used also when lateral thrusts and therefore lateral torsional stresses are continuously applied to the rear member 29 in competitions is provided by the ski 3
The terminal end portion of the rear extending portion 46 is coupled to the engaging member 47 fixed to the rear portion 4 so as to be movable in the vertical direction.

The coupling part that allows vertical movement but not lateral movement is in the form of a vertical guide 49. That is, the vertical facing surface 50 is the rearward extending portion 4
6 and the front portion of the engaging member 47, and guides the rear member 29 substantially vertically through most of the vertical swinging of the rear member 29.

An alternative to modifications with elastic members 45 may be used to connect the rearward extension 46, if any, to the upper surface 35 of the ski 34.
In a further improvement, the seat part 42 holding the elastic member 41 is provided with a hole 51 through which the auxiliary swing pivot 37 arranged in the rear member 29 is inserted. located within the front part.

With this improvement, when the secondary fixing pin 21 is pressed against the inclined surface 43, the secondary swinging pivot 37 overcomes the elastic resistance of the elastic member 41, so that the rear member 29 moves rearward.

When the sub-fixing pin 21 is fitted into its seat portion 39, the elastic member 41 pushes the sub-swinging pivot 37 back into the hole 51, allowing the rear member 29 to be accurately returned to the front member 27.

These improvements may be provided alone or in combination of two or more as necessary.

In the integrated joint 10 according to the present invention, the ninth to twelfth
As shown, an adjustable integral guide means 52 may be provided which also functions as the engagement member 47.

These guide means 52 extend over the entire length of the boot 17 and are adjustable, so that one guide means can be used for boots 17 of all sizes.

The guide member 53 of the guide means 52 of the type shown in FIG. 9 is provided with one or more slots 54 for receiving fixing screws 55 for adjusting the longitudinal position. These slots 54 are fitted with a lid 56 such as a fixed type.
(Fig. 10b).

The guide means 52 is fitted into the hollow part 19 of the sole 18 of the boot 17. They may be straight with a raised rear part (Fig. 11), or they may have a diffused rear part, their upper part may be straight or arcuate, or they may have a corner or a long square pyramid.
A plurality of longitudinal protrusions can be provided.

These guide means 52 can therefore be of any useful shape. In front of them is provided an elastic member 45, which cooperates with the four parts 59 provided on the underside of the rearward extension 46 to provide lateral support.

In this embodiment, the elastic member 45 is supported and fixed on the front extending surface 57 of the guide member 53, and is attached to the guide body 53 at a portion 58.

The guide means 52 is positioned relative to the rear extension 46 by marking the front extension surface 57 or the elastic member 45 with marks of various sizes (for example, an even number from Dx, an odd number from SX), and then the guide means 52 is positioned relative to the rear extension 46. By fixing them with screws 55, accurate mutual positioning corresponding to the size of the boot 17 can be performed.

In this way, the entire length of the boot 17 is guided and the joints can provide adequate lateral support.

FIG. 11 shows yet another modification example. In this case as well, the elastic member 45 is fixed to the guide means 52, but it can also be fixed to the rear extending portion 46. In this embodiment, the guide means 52 comprises a longitudinally movable member 53 and a fixed member 153.

The fixed member 1534 is fastened to the ski 34 with a screw 61, and forms a guide notch 60 for sliding the front blade 62 of the movable member 53. This front blade 62 may be marked with various size symbols so that it can be adjusted to suit the size of the boot by longitudinally positioning the blade 62 relative to the edge of the securing member 153.

In this case too, at least one slot 54, a screw 55 and a lid 56 are provided.

Slots 54 may be replaced by a series of holes or one hole of each size. If there is only one hole, you will have to drill a hole in the ski each time you adjust the size.
