SUMMARY OF THE INVENTION In order to solve this problem, according to the present invention, the hardness of a sliding equipment for snow, such as an alpine ski or a snowboard, which has an archbend height pre-defined in a manufacturing plant. A device for changing elasticity or rigidity, wherein a curing device attachable to a sliding device is provided, and the action of the curing device on the sliding device is selectively applied in two directions using a handle. It is variable by means of an operable control mechanism, the curing device being configured transversely to its longitudinal direction and divided into two sections, both sections using a spring system at the division points. Coupled to one another, the spring system having at least one spring, the spring contacting the first section of the curing device at its first end section, The second end section is in contact with the second section and the value of the degree of action of the stiffening device is manually and continuously adjustable by means of a control mechanism, whereby the archbend height of the gliding device is increased. Is variable with respect to its unloading state, and furthermore both sections of the curing device are pressure-loaded during operation in one direction and the other by force-transmitting means assigned to the control mechanism and loaded by the handle. In a type in which a tensile load is applied when operating in the direction, the control mechanism is arranged as a force transmitting means so as to be rotatable around a centering pin supported by the base body and selectively 1 An eccentric device which is brought into one of the two inoperative positions or one of the two inoperative positions, the eccentric devices being viewed in the height direction and having It has three staggered sections, a protrusor, an eccentric body and an upper part, in which the eccentric device is arranged concentrically with a vertical centering pin, the eccentric body of the eccentric device being in front of the hardening device. In the inactive position of the control mechanism between the eccentric body and the longitudinal cutout limiting wall of the front section of the curing device, which is engaged in the longitudinal cutout of the section surrounded by the limiting wall. As can be seen, there is a space on each side forming one space, the space between the eccentric body and the longitudinal notch limiting wall even when the curing device is shifted in the longitudinal direction. At, it still forms a space, if reduced, and the eccentric device is loaded by a centering spring and kept in its inactive position.

[0005]

As constructed according to the invention, between the eccentric body of the control mechanism occupying the neutral position and the limiting wall of the longitudinal notch in the front section of the curing device: In both the position where the stiffening device is not operated and the position where the stiffening device is shifted in the longitudinal direction due to the flexure of the ski, it is reduced to both sides starting from the individual intervals (a), even during the longitudinal shift. No force is transmitted from the curing device to the control mechanism due to the remaining space, if at all. The control mechanism is then kept in its inoperative position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

A ski 1 is schematically shown in FIGS. 1 to 4, and a toe piece 2 and a heel piece 3 are fixed to an upper side surface 1a of the ski 1. Further mounted on the ski 1 is a stiffening device 4 divided by a spring system 5, the rear section 4b of which stiffens at its end, in the illustrated embodiment in the immediate vicinity of the heel piece 3. It is fixed to the plate upper side surface 1a. The front section 4a extends through the toe piece 2 and engages at its end section with a control mechanism 6 for fixing the ski.

As is well known, skis are manufactured according to their respective products.

The plates can be tailored as desired by the user.

The control mechanism 6 comprises a base body 7, as shown in FIGS. 5 to 8, which is fixed by means of screws 8 which are shown schematically on the ski upper surface 1a. In the base body 7, the front section 4a of the curing device 4 is guided under the cover 13 of the base body 7 so as to be slidable in the horizontal direction. Further, the control mechanism 6 has an eccentric device 9, and the eccentric device 9 is provided with a centering pin 12 concentrically passing through the eccentric device.
The centering pin 12 is supported by the base body 7. The eccentric devices 9 are offset from each other when viewed in the height direction.
One section, namely the protrusion 9e, the eccentric body 9b, and the upper portion 9a.
And The front section 4a of the curing device 4 is provided with a vertically elongated notch 4c surrounding the limiting wall 4c ', and the eccentric body 9b of the eccentric device 9 is engaged with this notch 4c. The upper part 9a of the eccentric device 9 is provided with a swivel bearing 10 for a handle which is swivelable about a transverse axis 10a and is designed as a swivel lever 11.

As is apparent from FIG. 6, in the neutral position of the control mechanism 6, in which the eccentric device 9 occupies its inactive position, between the eccentric body 9b and the limiting wall 4c 'of the longitudinal notch 4c. On both sides there is a space indicated as the spacing a. As a result, no force is transmitted to the control mechanism 6 by the movement of the curing device 4 in this position of the control mechanism 6. However, also in this position to avoid automatic pivoting of the eccentric device 9,
The eccentric device 9 has a protrusion 9e in a section adjacent to the base body 7, and the side walls 9f ₁ and 9f ₂ of the protrusion 9e are supported by an additional portion 7b protruding upward from the base body 7. Centering spring 1 which has a substantially U-shape in plan view
9 are engaged at their legs 19a, 19b. The pivoting of the eccentric device 9 to the working position is carried out against the closing force of the centering spring 19, as will be explained in more detail below.

When the ski runs on a bumpy slope, the ski is bent. This causes a relative movement of the stiffening device 4 with respect to the ski 1, and thus a relative movement of the stiffening device 4 with respect to the control mechanism 6 for fixing the ski. FIG. 7 shows the position in which the curing device 4 has been shifted towards the tip of the ski (to the left in the plane of the drawing). However, even in this case, the control mechanism 6 remains in the neutral position. This is because even during extreme longitudinal shifts of the curing device 4, between the eccentric body 9b and the limiting wall 4c 'of the longitudinal notch 4c of the front section 4a, even if reduced. This is because there is a space and the eccentric device 9 is kept in its inactive position by the centering spring 19.

In the outwardly swung state, the swiveling lever 11 can easily swivel the eccentric device 9 about the centering pin 12 selectively in two directions with respect to its inactive position. , Whereby the front section 4a of the stiffening device 4 uses its longitudinal notch 4c to formschluessig-engage with the eccentric 9b. As a result, the curing device 4 is pressed toward the rear end of the ski (to the right) or toward the front end of the ski (to the left), depending on the direction of rotation of the eccentric device 9. It is tensile loaded and shifted so that the ski has a corresponding arch bend height h ₂ or h.
₃ is produced. FIG. 8 shows the control mechanism 6 in the working position for applying the pressing force, in which case the stiffening device 4 is in the position shifted towards the rear end of the ski, that is to the right in the drawing plane. The result is that the archbend height of the ski 1 is changed as shown in FIG. In this position, the centering pin 19 supports the working position of the eccentric device 9, in which case one leg 19a of the centering spring 19 is supported on the flatly chamfered lateral wall 9g of the projection 9e.

The front section 4a of the curing device 4 is constructed in two parts in the illustrated embodiment, in which case the longitudinal cutout 4c is located in the extension section 4a '. This extension category 4
The a'is rigidly connected to the front section 4a, for example by means of rivets 14. With this configuration, manufacturing technical advantages are obtained due to the configuration of the vertically long notch 4a.
Thus, in this case, for example, if the front section 4a of the curing device 4 is integral, it is possible, if desired, to use an extension section 4a 'with longitudinally different notches 4c of different configurations. is there.

The configuration of the control mechanism 6 and the curing device 4 as described above further makes the use of the mounting adjustment device more versatile. That is, using the attachment adjustment device, the longitudinal cutout 4c in the front section 4a of the curing device 4
It becomes possible to define the adjustment of the eccentric body 9b with respect to, accurately and while compensating for manufacturing and assembly errors. The details of such an attachment adjusting device are shown in FIG. 9, and in FIG. 9, the toe piece 2 is shown by a dashed line to make the drawing easy to see.

As shown in FIG. 9, the base body 7 is composed of two spring-elastic tongues 7d and 7e, and the two tongues 7d and 7e are assembled one by one in the curing device 4. The notches 22a and 22b are detachably locked.
Due to this configuration, both the spacing a between the eccentric 9b and the limiting wall 4c 'of the longitudinal cutout 4c of the front section 4a of the stiffening device 4 is ensured to the desired value in each case. Can be equivalent. When the hardening device 4 moves relative to the ski 1, both spring-elastic tongues 7d, 7e
Are pushed out of the cutouts 22a, 22b associated with the tongue, so that the stiffening device 4 can slide in the longitudinal direction with little resistance.

In the section of the base body 7 which is penetrated by the screw 8 of the toe piece 2, vertically elongated notches 21a, 2
1b is provided, which makes it possible to compensate for differences in length when mounting the toe piece 2.

The invention is not limited to the embodiments shown and described, but various variants are possible within the framework of the invention. For example, the swivel lever, which acts as a handle, may be unter Reibschluss-bearing for holding in the closed position, or in each of its two end positions with a spring-loaded locking device. It may be adapted to engage with one locking position. Spring-loaded locking devices with balls or pins have been known for some time in ski binding constructions, and notches serving as locking points are also known. However, it is also possible to load the pivot lever with a light spring acting in the closing direction.

In particular, if the cover is made of a flexible plastic material so as not to interfere with the mounting of the eccentric device, it is possible to construct the cover integrally with the base body.

The centering spring may also have a different construction than described above or shown. For example, a spiral spring is arranged between the base body and the eccentric device,
The spiral spring may engage the base body at one end section and the eccentric device at the other end section. It is therefore advantageous if the spiral spring is adapted to be brought into contact with a correspondingly shaped section of the eccentric device. Because of this, the centering of the eccentric body or its sections is form-coupling (formal).
schlussig) That is because it is done by binding by shape.

In a further advantageous development of the invention, the spring system has two spring groups acting independently of one another, the first of which is formed from two springs. And the second spring group is formed from at least one spring, the springs belonging to the first spring group being able to be supported in the first section at their first end section and at the second end. The partial section can be supported by the second section and the first force-transmitting member belonging to the first section, and advantageously only one spring belonging to the second spring group has its first section. Of the second section and a second section and a second force transmitting member of the first section of the curing device.
